[Cross-reference to related applications]
This application claims priority to Chinese Patent Application No. 201811602882.3 named "NETWORK SEARCH LIST GENERATION METHOD, NETWORK SEARCH METHOD, AND CORRESPONDING APPARATUS" filed with the China National Intellectual Property Office on December 26, 2018. However, the entire contents will be referred to.

[Technical field]
This application relates to the field of communication technology, specifically, a network search list generation method, a network search method, and a corresponding device.

The Public Land Mobile Network (PLMN) is a network that provides land mobile communication services to the public. This network is usually interconnected with the Public Switched Telephone Network (PSTN) to form a communication network for all regions, nationwide, etc. In this case, the user equipment (UE) may realize communication by using the PLMN provided by each operator.

With the development of communication technology, each operator can support multiple types of network standards. In some cases, device leasing may occur between operators, taking into account commercial factors, etc., that is, Operator A rents Operator B's device in some areas or for some standards, thereby. Operator A does not need to deploy the corresponding device in these areas or for these standards. For example, China Mobile has global system for mobile communication (GSM), time division-synchronous code division multiple access (TD-SCDMA) and time division long. It can support network standards such as time division long term evolution (TD-LTE), and China Unicom can support network standards such as GSM. In some areas, China Mobile can only deploy the devices required by TD-SCDMA and TD-LTE, and in these areas can rent the devices required by GSM deployed by China Unicom. As a result, China Mobile does not need to deploy the devices required by GSM.

When Operator A rents Operator B's device, usually to allow Operator A's subscriber identity module (SIM) to perform communication on the communication network corresponding to the leased device. Now, the network support information is set on the SIM card. The network support information indicates that the SIM card will use each of the network standard communication networks supported by Operator A and Operator B as an equivalent home public land mobile network (Equivalent HPLMN, EHPLMN) in the network discovery process. , UE can find a communication network corresponding to the leased device in order to realize communication by using the communication network.

However, in the research process of this application, the inventor in the prior art, if the UE using Operator A's SIM card camps in a communication network corresponding to the leased device, the network after network handover occurs. Because it camps on the communication network corresponding to the leased device provided by operator B prior to handover, the UE preferentially selects other network standards supported by operator B in the network discovery process and the UE. After determining that it cannot camp on another network standard supported by operator B, the UE explores the network in the network standard supported by operator A and communicates by using the network standard supported by operator A. I'm finding something to do. Since the network search process in other network standards supported by operator B takes a certain period of time, the period required by the network search process becomes longer. As a result, network exploration is relatively slow, network camp speed is further affected, and network camp efficiency is reduced. Therefore, the user experience is poor.

In the prior art, when Operator A's SIM card camps on the communication network corresponding to the leased device, network exploration is relatively slow, network camp speed is affected, and network camp efficiency is high after network handover occurs.

In the prior art, when Operator A's SIM card camps on the communication network corresponding to the leased device, network exploration is relatively slow, network camp speed is affected, and network camp efficiency is high after network handover occurs. It will be reduced. To solve the above problems, embodiments of this application disclose a network search list generation method, a network search method and a corresponding device.

The solutions disclosed in embodiments of this application apply to user devices capable of performing communication services, such as smartphones and watchphones. As shown in FIG. 1, which is a schematic diagram of the structure of the user device, the user device includes a non-access stratum (NAS) and an access layer (access stratum, AS), and the non-access layer is a core network. It is a functional layer that is located between and the user device and can support signaling and data transmission between the core network and the user device, and the access layer is usually user connection or access oriented and network the user device.

Further, the non-access layer can interact with the access layer, whereby the access layer can acquire the network search list, and the access layer can realize the network camp based on the network search list.

In order to clarify the solution disclosed in the embodiment of this application, the solution of this application is disclosed below by using the embodiment.

The first embodiment of this application discloses a method for generating a network search list. Referring to the schematic of the workflow shown in FIG. 2, the network search list generation method includes the following steps.

Step S11: The non-access layer in the user appliance UE acquires the network access information of the UE, and the network access information includes the UE's equivalent home public land mobile network EHPLMN and the network type corresponding to the EHPLMN.

The network access information may be stored in advance in the UE's local cache space, for example, in the UE's non-volatile flash memory space, or in the UE's SIM card. In addition, network access information may also be located on the server. That is, the network access information storage module may be the UE's local cache space, SIM card and / or server. When the network access information is located on the server and the UE has not completed camping on the network, the UE may access the server by connecting to wireless network Wi-Fi etc., thereby the non-access layer. Gets network access information.

The network access information includes the UE's equivalent home public land mobile network EHPLMN and the network type corresponding to the EHPLMN. The EHPLMN indicates a list formed by a home PLMN (Home PLMN, HPLMN) or the like supported by the SIM card in the UE, and the HPLMN supported by the SIM card may be represented in the form of a network code. For example, HPLMNs supported by China Mobile SIM cards include 46000, 46002 and 46007, and HPLMNs supported by China Unicom SIM cards include 46001. However, the network type corresponding to EHPLMN indicates the network type corresponding to each home network supported by the SIM card in the UE, and the network type may be GSM, TD-SCDMA, TD-LTE, or the like.

If China Mobile deploys only the equipment required by the TD-SCDMA and TD-LTE networks in the area and rents the equipment required by the GSM network and deployed by China Unicom, use China Mobile's SIM card in this area. The UE EHPLMN used includes 46000, 46002, 46007 and 46001. In addition, the network types corresponding to 46000, 46002 and 46007 include various network types of China Mobile, namely GSM, TD-SCDMA and TD-LTE. The network type corresponding to 46001 is the network type supported by China Unicom's leased devices, namely GSM.

Step S12: The non-access layer determines the target network to be explored by the UE in the network discovery process when the UE performs communication by using each network type based on the network access information.

For example, the EHPLMN in the access information includes 46000, 46002, 46007 and 46001, and the network types corresponding to 46000, 46002 and 46007 are the various network types of China Mobile, namely GSM, TD-SCDMA and TD-LTE. The network type corresponding to 46001 is the network type supported by China Unicom's leased devices, ie GSM. In this case, when the UE is handed over to 2G, in other words, when the network type, i.e., GSM is used for communication, the target networks explored in the network discovery process include 46000, 46002, 46007 and 46001. When the UE is handed over to 3G, in other words, when the network type, ie TD-SCDMA, is used for communication, the target networks searched in the network discovery process include 46000, 46002 and 46007, and the UE is 4G. When handed over to, in other words, the network type, ie, when the TD-LTE is used for communication, the target networks searched in the network search process include 46000, 46002 and 46007.

Step S13: The non-access layer generates a network search list containing the correspondence between the network type and the target network based on the target network searched by the UE in the network search process.

After obtaining the network discovery list, the access layer can determine the corresponding target network based on the corresponding network type during the network camp and search for the target network.

In the network search list generation method disclosed in this embodiment of this application, the non-access layer in the UE acquires the network access information of the UE, and the network access information is the equivalent home public land mobile network EHPLMN of the UE. The non-access layer includes the network type corresponding to the EHPLMN, and then the non-access layer is the target searched by the UE in the network discovery process when the UE performs communication by using each network type based on the network access information. The network is determined and the non-access layer generates a network discovery list containing the correspondence between the network type and the target network based on the target network explored by the UE in the network discovery process.

In the prior art, when operator A rents operator B's device, the communication network supported by operator A and operator B is located on the SIM card's equivalent home land locomotive network EHPLMN. For example, China Mobile supports 2G GSM communication network, 3G TD-SCDMA communication network and 4G TD-LTE communication network, and China Unicom supports 2G GSM communication network, 3G wideband code split multiple connection (wideband). Supports code division multiple access (W-CDMA) communication networks and 4G frequency division duplexing long term evolution (FDD-LTE) communication networks. In this case, if China Mobile can place only the devices required by the TD-SCDMA and TD-LTE networks in the area and rent the devices required by the GSM network and placed by China Unicom in this area. , China Mobile SIM card EHPLMN includes 46000, 46002, 46007 and 46001.

In this case, if Operator A's SIM card camps on the communication network corresponding to the leased device, after the network handover occurs, the SIM card will be the leased device provided by Operator B before the network handover. In order to camp on the corresponding communication network, the SIM card preferentially selects other network standards supported by operator B in the network discovery process, and the SIM card in other network standards supported by operator B. After deciding that the camp cannot be achieved, the SIM card explores the network in the network standard supported by Operator A and performs communication by using the network standard supported by Operator A. The network discovery process in other network standards supported by operator B takes a certain period of time, which increases the period required by the network discovery process. As a result, network exploration is relatively slow, network camp speed is further affected, and network camp efficiency is reduced. Therefore, the user experience is poor.

For example, if the UE camps on a GSM network, after the network handover occurs, the UE is handed over to the 3G network, and if the UE previously camps on the GSM network, the UE should use China Unicom's device. The UE's EHPLMN includes communication networks supported by both China Mobile and China Unicom. In this case, after the UE is handed over to the 3G network, the UE first attempts to search and register the 3G network (ie, 46001) provided by China Unicom in the network search process. However, UE access is denied by China Unicom. In this case, it is shown that the network search fails after the network search period. The UE then explores the 3G networks provided by China Mobile (ie 46000, 46002 and 46007) based on the EHPLMN records. However, the process of exploring the 3G network provided by China Unicom takes a period of time. As a result, the duration required by the overall network exploration process is relatively long, which further reduces network camp speed and network camp efficiency, thereby impacting the user experience.

However, according to the solution disclosed in this embodiment of this application, the network search list generated by the non-access layer includes a correspondence between the network type and the target network. In this case, when performing a network discovery based on the network discovery list, the access layer can determine the target network that needs to be explored based on the network type used during the network discovery, thereby being supported. Avoid exploring open communication networks, reduce the time required by the network exploration process, and further accelerate network camps. This improves network camp efficiency and user experience.

For example, according to the solution in this embodiment of this application, the network type corresponding to EHPLMN can be represented in the network search list. In this case, after the UE has been handed over from 2G to 3G (in other words, the network type, ie TD-SCDMA needs to be used for communication), the target networks searched in the network search process are 46000, 46002. And 46007 may be determined to include. In other words, based on the network search list obtained in this embodiment of this application, the access layer will directly search for 46000, 46002 and 46007 instead of searching the 3G network (ie 46001) provided by China Unicom. Explore and thereby avoid exploring unsupported communication networks.

In the prior art, the EHPLMN supported by the SIM card is usually recorded on the EHPLMN list, and the SIM card's forbidden network (Forbidden PLMN, FPLMN) may also be recorded on the FPLMN list. Each communication network recorded in the EHPLMN list and the FPLMN list is usually represented by using 3 bytes.

For example, in the prior art, the EHPLMN list may be represented by using Table 1.

In Table 1, 1-3 bytes describe the first communication network in the EHPLMN, the description occupies a length of 3 bytes, 22-24 bytes describe the eighth communication network in the EHPLMN, and the description is 3. Indicates that it occupies the length of the byte.

However, in this embodiment of this application, two bytes may be added to the corresponding location of each communication network included in the EHPLMN list to indicate network access information. For example, the network access information of the UE may be represented by using Table 2.

In Table 2, 1-3 bytes describe the first communication network in the EHPLMN (eg 46000), the description occupies a length of 3 bytes, and 4-5 bytes correspond to the communication network (eg 46000). , GSM), the description occupies 2 bytes, 36-38 bytes describe the 8th communication network in EHPLMN, the description occupies the length of 3 bytes, 39-40 bytes in the communication network. Describe the corresponding network type and indicate that the description occupies a length of 2 bytes.

Obviously, network access information may be represented in other formats as an alternative. This is not limited to this embodiment of this application.

Further, in this embodiment of this application, the non-access layer acquiring the network access information of the UE is as follows, that is,
The non-access layer reads the storage space of the UE and acquires the network access information stored in the storage space in advance.
The non-access layer reads the subscriber identification module SIM card in the UE and acquires the network access information stored in advance in the SIM card.
This includes one or more of the non-access layer accessing the cloud through a wireless network and acquiring network access information pre-stored in the cloud.

The SIM card may be in multiple formats. For example, the SIM card may be a physical SIM card. Further, the SIM card may be an embedded SIM (Embedded-SIM, eSIM) card as an alternative. This is not limited to this embodiment of this application.

In addition, the network access information may change. For example, if the device lease relationship between operators changes, the network access information will change accordingly. The network access information may be further updated to avoid affecting the UE's network search results.

In this case, when the network access information is stored in the storage space of the UE or stored in the SIM card, the method disclosed in this embodiment of this application is:
The non-access layer accesses the cloud at preset period intervals and acquires the network access information stored in the cloud.
The non-access layer further includes updating the network access information stored in the UE storage space or stored in the SIM card by using the network access information stored in the cloud.

According to the above steps, the non-access layer acquires the network access information stored in the cloud by accessing the cloud at preset period intervals, and the network access in the storage space of the UE or the SIM card. You may update the information.

The non-access layer may access the cloud when the network camp is realized, or the non-access layer may access the cloud by connecting to the wireless network.

Further, when network access information is stored in the UE's storage, update software may be further deployed in the UE. The update software updates the network access information in the UE's storage space by using the acquired update data packet. The update data packet may be a software package generated by the UE manufacturer and used for system upgrades.

Further, in this embodiment of this application, after the non-access layer has acquired the network search list, the access layer needs to perform a network search based on the network search list. In this case, after the non-access layer has generated a network discovery list containing the correspondence between the network type and the target network, the method is
The non-access layer further includes sending the network discovery list to the access layer in the UE.

According to the above steps, the access layer gets the network discovery list, gets the network discovery list, and then determines the target network of the current network discovery based on the current network discovery target network type and the network discovery list. Can make decisions and perform network exploration.

Alternatively, after the non-access layer has generated a network discovery list containing the correspondence between the network type and the target network, the method is
The non-access layer determines the target network type for current network exploration,
The non-access layer determines the target network corresponding to the target network type based on the correspondence between the network type and the target network included in the network discovery list.
The non-access layer splits the network discovery list and sends the split network discovery list to the access layer in the UE, which further includes including the target network corresponding to the target network type. ..

According to the above steps, the non-access layer divides the network discovery list based on the target network type of the current network discovery, and the divided network discovery list contains the target networks corresponding to the target network type and is non-accessible. The access layer sends a divided network search list to the access layer, whereby the access layer can realize a network search based on the divided network search list.

For example, the network discovery list shows that the networks supported by the SIM card include 46000, 46002, 46007 and 46001, 46000, 46002 and 46007 correspond to the GSM, TD-SCDMA and TD-LTE network types. When 46001 corresponds to the GSM network type, the network type, that is, the target network corresponding to GSM includes 46000, 46002, 46007 and 46001, and the target network corresponding to both TD-SCDMA and TD-LTE is. It may be determined to be 46000, 46002 and 46007. If the current network search target network type is TD-SCDMA, the target networks included in the split network search list include 46000, 46002 and 46007. In this case, after receiving the divided network search list, the access layer performs a network search based on the divided network search list.

To illustrate in detail how the non-access layer determines the target network type for current network exploration, this application discloses other embodiments. Referring to FIG. 3, in this embodiment, the non-access layer determining the target network type of the current network search includes the following steps.

Step S21: When the currently generated network discovery list is the first network discovery list generated after the UE powers up, the non-access layer queries the UE usage log for the previous power up process. Gets the network type of the communication network finally used by the UE in.

Step S22: The non-access layer determines the network type of the communication network that was ultimately used by the UE in the previous power-on process as the target network type for the current network exploration.

In other words, the target network type for the current network search may be determined based on the historical usage of the UE.

For example, the currently generated network discovery list is the first network discovery list generated after the UE powers up, and by querying the UE usage log, it is finally used by the UE in the previous power up process. If it is determined that the network type of the communication network is TD-SCDMA, the non-access layer determines that the target network type of the current network search is TD-SCDMA. In other words, when the currently generated network discovery list is the first network discovery list generated after the UE powers up, the current network discovery target network type is finalized by the UE in the previous power up process. Determined based on the communication network used for.

Alternatively, in other schemes, the non-access layer determines the target network type for the current network search, after receiving the first network handover operation, the non-access layer goes to the first network handover operation. Includes determining the target network type for the current network exploration based on.

The first network handover operation can indicate the target network type of the current network search. For example, the first network handover operation is used to allow the UE display to display multiple network types, and the non-access layer selects a network type from multiple network types as the target network type. .. After receiving the first network handover operation, the non-access layer determines the target network type of the current network search based on the first network handover operation.

In one example, the display interface of the UE display may be that shown in FIG. The network list is displayed on the display interface and the network list includes multiple network standards such as 2G, 3G and 4G. When the user performs the first network handover operation, the display of the UE may show the interface, and the network type corresponding to the network standard selected by the user is used as the target network type.

For SIM cards provided by different operators, each network standard corresponds to the network type supported by the operator. For example, when the SIM card in the UE is a SIM card provided by China Mobile, 2G supports GSM, 3G supports TD-SCDMA, and 4G supports TD-LTE. In this case, when the user selects 3G, the network type TD-SCDMA corresponding to 3G is the target network type.

Further, if the display interface of the UE's display is that shown in FIG. 4, information such as the priority of each network standard may be further displayed in the block after the network standard.

In the process of using the UE, the user may perform a network handover operation on the UE, whereby the UE is subject to network handover, for example, the UE is handed over from TD-SCDMA to TD-LTE. In this case, according to the above description, the non-access layer can determine the target network type of the current network search based on the received network handover operation.

Alternatively, in other schemes, referring to the workflow schematic shown in FIG. 5, the non-access layer determining the target network type for the current network exploration includes the following steps.

Step S31: The non-access layer gets the preset priorities for each network type.

Step S32: The non-access layer determines the network type that currently has the highest priority as the target network type for the current network exploration.

Step S33: When network discovery is performed by using the network type with the highest priority and the network discovery fails, the non-access layer sequentially other networks based on the priority corresponding to each network type. Select the type as the target network type for the current network discovery.

In this embodiment of this application, the user may preset priorities corresponding to each network type. In this case, the non-access layer determines the target network type based on the specified priority. Specifically, the non-access layer determines the network type that currently has the highest priority as the target network type for the current network search. In this case, if the access layer fails to explore the network, the non-access layer selects the network type that has the second highest priority after the highest priority as the target network type for the current network exploration. That is, in this solution, the target network types are sequentially selected based on the preset priorities of each network type.

In addition, the priorities for each network type can be changed to meet diversifying user requirements. For example, at the beginning of each month, the UE's network traffic is relatively sufficient and users pay more attention to network speed. In this case, the network type, i.e., TD-LTE, may be set with the highest priority, whereby the access network preferentially searches the TD-LTE network during the network search. In addition, at the end of the month, the UE's network traffic is relatively low and users need to save traffic. In this case, the network type, i.e., the GSM, may be set with the highest priority, whereby the access network preferentially searches the GSM network during the network search.

If the display interface of the UE display is that shown in FIG. 4, the priority of each network standard may be further displayed in the block behind the network standard, and the user may further modify the information in the block. , The priority of each network standard may be changed. For SIM cards provided by different operators, each network standard corresponds to the network type supported by the operator. Therefore, the priority of each network type can be changed by changing the priority of each network standard.

For example, when the SIM card in the UE is a SIM card provided by China Mobile, 2G supports GSM, 3G supports TD-SCDMA, and 4G supports TD-LTE. In this case, when the user changes the 3G priority, the TD-SCDMA priority will change accordingly.

In addition, the non-access layer may further determine the target network type for current network exploration based on the UE's application parameters. In this case, referring to the schematic of the workflow shown in FIG. 6, the non-access layer determining the target network type of the current network search includes the following steps.

Step S41: After receiving the second network handover operation, the non-access layer acquires the application parameters of the UE, which includes the address and / or time.

The second network handover operation is used to indicate that the network handover currently needs to be performed, whereby the non-access layer determines the target network type for the current network exploration.

The UE usually has a built-in clock, and the non-access layer may acquire the time by using the built-in clock of the UE. Further, the UE may realize UE positioning through a wireless network, whereby the non-access layer acquires the address of the UE. For example, the UE may achieve positioning by connecting to Wi-Fi and using the Global Positioning System (GPS), whereby the non-access layer acquires the address of the UE. ..

Step S42: The non-access layer determines the priority of each network type based on the UE's application parameters and the preset correspondence between the application parameters and the network type's priority.

In this embodiment of this application, the correspondence between application parameters and network type priorities may be preset and the correspondence may be stored in the form of a table or the like. Further, the correspondence may be further modified according to the user's requirements.

Step S43: The non-access layer determines the network type with the highest priority as the target network type for the current network search.

In this embodiment of this application, the non-access layer gets the application parameters of the UE and each network is based on the application parameters of the UE and the preset correspondence between the application parameters and the network type priority. Determine the priority of the type and use the network type with the highest priority as the target network type for the current network discovery.

According to the solution in this embodiment of this application, the non-access layer can determine the priority of each network type based on the application parameters and further determine the target network type of the current network exploration. For example, a user departs from location A to location B for work every day. The TD-LTE signal strength at location A is strong, and the GSM signal strength at location B is strong. In this case, the user may set that TD-LTE has the highest priority when the UE is located in location A and GSM has the highest priority when the UE is located in location B. good. In this case, when the non-access layer determines based on application parameters that the UE is located at location A, the network type, i.e., TD-LTE, may be determined as the target network type for the current network exploration. When the non-access layer determines that the UE is located at location B based on application parameters, the network type, ie GSM, may be determined as the target network type for the current network exploration.

Alternatively, in other schemes, referring to the workflow schematic shown in FIG. 7, the non-access layer determining the target network type for the current network exploration involves the following steps:

Step S51: After receiving the third network handover operation, the non-access layer acquires the application parameters of the UE, which includes the address and / or time.

A third network handover operation is used to indicate that a network handover currently needs to be performed, whereby the non-access layer determines the target network type for the current network exploration.

Further, the non-access layer may acquire the time by using the built-in clock of the UE. Further, the UE may realize UE positioning through a wireless network, whereby the non-access layer acquires the address of the UE. For example, the UE may realize positioning by connecting to Wi-Fi and using GPS, whereby the non-access layer acquires the address of the UE.

Step S52: When the UE is connected to a wireless network, the non-access layer acquires the signal strength sequence for each network type under application parameters by accessing the server.

When the UE is connected to a wireless network, the UE may access the server and, under the application parameters, obtain the signal strength sequence for each network type by accessing the server. For example, if the application parameter is a location, the signal strength sequence for each network type at that location may be obtained by accessing the server.

Step S53: The non-access layer determines the network type with the highest signal strength as the target network type for the current network search.

According to the solution in this embodiment of this application, the non-access layer obtains the signal strength sequence of each network type of UE under the current application parameters by accessing the server through the wireless network and signals. Based on the strength order, the network type with the highest signal strength can be determined as the target network type for the current network exploration.

In the network search list generation method disclosed in this embodiment of this application, the non-access layer is the UE in the network search process when the UE performs communication by using each network type based on the network access information. It is necessary to determine the target network to be searched by. This operation may be realized by a plurality of methods.

In one of the methods, the non-access layer determines the target network to be explored by the UE in the network discovery process when the UE performs communication by using each network type based on the network access information. teeth,
When the UE performs communication by using the first network type, the non-access layer finds the EHPLMN corresponding to the first network type in the network access information by the UE in the network discovery process. Including using as.

The network access information includes the UE's equivalent home public land mobile network EHPLMN and the network type corresponding to the EHPLMN, so that when communication is performed by using each network type, it is searched in the network discovery process. The target network can be determined based on the network access information.

For example, the EHPLMN in the access information of the UE includes 46000, 46002, 46007 and 46001, and the network types corresponding to 46000, 46002 and 46007 are the various network types of China Mobile, namely GSM, TD-SCDMA and TD. -The network type corresponding to 46001, including LTE, is the network type supported by China Unicom's leased devices, namely GSM. In this case, when the first network type is GSM and the UE performs communication by using the first network type, the target networks explored in the network discovery process are 46000, 46002, 46007 and 46001. Including, when the first network type is TD-SCDMA and the UE performs communication by using the first network type, the target networks explored in the network discovery process include 46000, 46002 and 46007. When the first network type is TD-LTE and the UE performs communication by using the first network type, the target networks searched in the network discovery process include 46000, 46002 and 46007.

Alternatively, in other schemes, the network access information further includes the UE's prohibited network FPLMN and the network type corresponding to the FPLMN, and the FPLMN and EHPLMN are usually set in a list. In this case, when the non-access layer decides that the UE will perform communication by using each network type based on the network access information, the non-access layer will search for the target network in the network discovery process. Normally, the FPLMN included in the list containing FPLMN and EHPLMN is removed, then the overlapping network of FPLMN and EHPLMN is determined, and when the UE performs communication by using each network type, the overlapping network and EHPLMN Is used as the target network that needs to be explored in the network discovery process.

According to the above solution, the overlapping network of FPLMN and EHPLMN may be used as the target network that needs to be searched in the network search process.

Correspondingly, this application discloses other embodiments. With reference to the schematic of the workflow shown in FIG. 8, this embodiment of this application discloses a network exploration method. The network search method includes the following steps.

Step S61: The access layer in the user equipment UE gets a network discovery list, the network discovery list contains the correspondence between the network type and the target network, and the target network is the target network where the UE uses each network type. Thereby, when performing communication, it is a network that needs to be searched in the network search process.

The access layer may acquire the network search list generated by the non-access layer by interacting with the non-access layer.

The network discovery list contains the correspondence between the network type and the target network, and the target network is the network that needs to be explored in the network discovery process when the UE performs communication by using each network type. Is. For example, when the UE performs communication by using the network type, ie GSM, the target networks explored in the network discovery process include 46000, 46002, 46007 and 46001, and the UE is the network type, ie, TD. -When performing communication by using SCDMA, the target networks searched in the network search process include 46000, 46002 and 46007, and the UE performs communication by using the network type, ie TD-LTE. When doing so, the target networks explored in the network discovery process include 46000, 46002 and 46007. In this case, the network search list shows the correspondence between GSM and 46000, 46002, 46007 and 46001, the correspondence between TD-SCDMA and 46000, 46002 and 46007, and the correspondence between TD-LTE and 46000, 46002 and Includes correspondence with 46007.

Step S62: The access layer determines the target network type for the current network exploration.

The method by which the access layer determines the target network type of the current network search may be the same as the method by which the non-access layer determines the target network type.

Specifically, when the network discovery list currently acquired by the access layer is the first network discovery list acquired after the UE powers up, the access layer previously by querying the UE usage log. Gets the network type of the communication network that was finally used by the UE in the power-on process of, and the network type of the communication network that was finally used by the UE in the previous startup process, the target network type of the current network discovery. May be used as.

In other words, the target network type for the current network search may be determined based on the historical usage of the UE. For example, the currently generated network discovery list is the first network discovery list generated after the UE powers up, and by querying the UE usage log, it is finally used by the UE in the previous power up process. If it is determined that the network type of the communication network is TD-SCDMA, the non-access layer determines that the target network type of the current network search is TD-SCDMA. In other words, when the currently generated network discovery list is the first network discovery list generated after the UE powers up, the current network discovery target network type is finalized by the UE in the previous power up process. Determined based on the communication network used for.

Alternatively, the access layer may determine the target network type for the current network search based on the received network handover operation.

The network handover operation received by the access layer can indicate the target network type of the current network search. For example, a network handover operation is used to allow a UE display to display multiple network types, and the access layer selects a network type from multiple network types as the target network type. After receiving the network handover operation, the access layer determines the target network type of the current network search in the network handover operation.

Alternatively, the access layer acquires a preset priority corresponding to each network type, and then determines the network type with the currently highest priority as the target network type for the current network exploration. When network discovery is performed by using the network type with the highest priority and the network discovery fails, the access layer will sequentially select other network types, currently, based on the priority corresponding to each network type. Further select as the target network type for network exploration.

In this method, the user may preset the priority corresponding to each network type. In this case, the non-access layer determines the target network type based on the specified priority. Specifically, the non-access layer determines the network type that currently has the highest priority as the target network type for the current network search. In this case, if the access layer fails to explore the network, the non-access layer selects the network type that has the second highest priority after the highest priority as the target network type for the current network exploration. That is, in this solution, the target network types are sequentially selected based on the preset priorities of each network type.

Alternatively, after receiving the network handover operation, the access layer gets the application parameters of the UE, the application parameters include the address and / or time, and then the access layer is the application parameters of the UE and the network with the application parameters. The priority of each network type is determined based on the preset correspondence with the priority of the type, and finally, the access layer determines the network type having the highest priority in the current network exploration. Determine as the target network type.

In this method, the access layer gets the application parameters of the UE and sets the priority of each network type based on the application parameters of the UE and the preset correspondence between the application parameters and the network type priority. The network type that is determined and has the highest priority is used as the target network type for the current network exploration.

Alternatively, after receiving the network handover operation, the access layer gets the application parameters of the UE, the application parameters include the address and / or time, and when the UE is connected to the wireless network, the access layer is By accessing the server, the signal strength sequence of each network type is acquired under the application parameters, and the access layer determines the network type with the highest signal strength as the target network type for the current network search.

In this method, the access layer can obtain the signal strength sequence of each network type of UE under the current application parameters by accessing the server through the wireless network, and based on the signal strength sequence, the highest signal strength. Can be determined as the target network type for the current network exploration.

Obviously, the access layer may otherwise determine the target network type for the current network search. This is not limited to this embodiment of this application.

Step S63: The access layer determines the target network for the current network search based on the target network type and the network search list, and performs the network search.

According to the solution according to this embodiment of this application, the network discovery list obtained by the access layer includes the correspondence between the network type and the target network, and the target network is such that the UE uses each network type. Thus, when performing communication, it is the network that needs to be explored in the network discovery process, the access layer determines the target network type for the current network discovery, and then based on the target network type and the network discovery list. , The target network of the current network search may be determined and the network search may be performed.

In this case, when performing a network discovery based on the network discovery list, the access layer can determine the target network that needs to be explored based on the network type used during the network discovery, thereby being supported. Avoid exploring open communication networks, reduce the time required by the network exploration process, and further accelerate network camps. This improves network camp efficiency and user experience.

Further, in this embodiment of this application, the method is performed after the access layer determines the target network for the current network search and performs the network search.
When a network search is performed m times against the target network of the current network search and the network search performed each time fails, the access layer redetermines the target network type of the current network search. Is a preset positive integer, and
The access layer further includes redetermining the target network for the current network search and performing the network search based on the redetermined target network type and network search list.

m is a preset positive integer. For example, m may be set to 5. In this case, all the network searches executed five times in a row fail, and the access layer may execute the network search by redetermining the target network and using the redetermined target network.

For example, if the access layer determines that the target network type is TD-LTE, but all network searches performed m times for each network corresponding to TD-LTE fail, the access layer is the target network. May redetermine that it is TD-SCDMA and use the network search list to determine the target network corresponding to TD-SCDMA and perform the corresponding network search.

Other embodiments of this application disclose a network search method. With reference to the schematic of the workflow shown in FIG. 9, the network search method disclosed in this embodiment of this application comprises the following steps:

Step S71: The access layer in the user equipment UE gets a network discovery list, which includes the target network corresponding to the target network type of the current network discovery.

In this case, the non-access layer determines the target network type for the current network exploration and obtains the partitioned network exploration list, which contains the target networks corresponding to the target network type. The access layer acquires a divided network search list by interacting with the non-access layer.

For example, if the non-access layer determines that the current network search target network type is TD-SCDMA, then the network search list obtained by the access layer is the network type, ie, the target network corresponding to TD-SCDMA. including.

Step S72: The access layer performs a network search based on the network search list.

According to the solution disclosed in this embodiment of this application, when performing a network search based on a network search list, the access layer can determine the target network corresponding to the target network type of the current network search. This avoids exploring unsupported communication networks, reduces the time required by the network exploration process, and further accelerates network camps. This improves network camp efficiency and user experience.

Further, in this embodiment of this application, the method is performed after the access layer performs a network search based on the network search list.
When the network search is performed n times and the network search performed each time fails, the access layer reacquires the network search list, and the reacquired network search list is the redetermined target network type. Containing the target network corresponding to, n is a preset positive integer, and
The access layer further includes performing a network search based on the reacquired network search list.

n is a preset positive integer. For example, n may be set to 5.

For example, if the current network search target network type is TD-LTE, but the network search performed n times for each network corresponding to TD-LTE fails, this was acquired in step S71. The network discovery performed by using the network discovery list indicates that it is impossible to succeed, and the access layer may reacquire the network discovery list by interacting with the non-access layer. For example, a network search list including each network corresponding to TD-SCDMA may be acquired, and the access layer re-executes the network search.

According to the above solution, the access layer can reacquire the network search list and perform a network search based on the reacquired network search list.
