Description

Network access processing method and terminal equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a network access processing method and a terminal device.

Background

In 4 months 2014, the three-network dual-standby 3G smart internet phone is released by the china telecom in the first world, and can be compatible with a Code Division Multiple Access (CDMA) network, a GSM (Global System for Mobile Communication) network and a GSM network, which are called "all-network-through" phones. The series of mobile phone products with brand new marketing concept realizes the 'integration' of three operators on the mobile phone, is compatible with voice and data services of three networks of China telecom CDMA network, China Mobile GSM network and China Unicom GSM network, has the greatest characteristic of multiple functions, keeps two networks online at the same time, and means that users of China Mobile and China Unicom can use 3G network mobile phones of China telecom sky wings without replacing old numbers of the original operators. And keep both nets online at the same time. Namely, the basic definition of the mobile phone with full network communication is as follows: the 4G (the 4th Generation mobile communication)/3G (the 3th Generation mobile communication)/2G (the 4th Generation mobile communication) network of the mobile, telecom operator can be used, that is, the SIM card of the telecom operator can be used. The 4G includes two systems, namely Time Division Long Term Evolution (TD-LTE) and orthogonal Frequency Division multiple access (FDD-LTE), which may also be referred to as Long Term Evolution (LTE).

For the multimode terminal equipment supporting 4G, when a user identity identification card (such as a SIM card) of a user does not support 4G, when accessing an LTE network, the user is rejected by various cause values at the network side to move a user of a unified card, and a USIM card not signing 4G accesses LTE, and the user is rejected by the cause value of "# 7EPS service not allowed" at the network side, and for a user of a telecommunication card, the user is rejected by the cause value of "# 15No able cells in tracking area" at the network side. However, for a terminal device (a terminal device supporting multiple modes) communicating through the whole network, it is currently preferred to try to access an LTE network, that is, after the terminal device is powered on, LTE is preferentially searched. This results in the SIM card not subscribed to LTE being rejected by the network test only when attempting access after searching for an LTE network. That is, the terminal device will try other system networks only after the SIM card fails to try to access the LTE. Therefore, when the terminal device needs to be powered on and registered each time, the time for acquiring the service is increased, so that the waiting time of the user is prolonged, and the user experience is seriously influenced.

The terms "first," "second," "third," and "fourth," etc. in the description and claims of the invention and in the accompanying drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Hereinafter, some terms in the present application are explained to facilitate understanding by those skilled in the art.

1) A terminal device, also called a User Equipment (UE), is a device providing voice and/or data connectivity to a User, such as a handheld device with a wireless connection function, a vehicle-mounted device, and so on. Common terminal devices include, for example: a Mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device, an intelligent bracelet, a pedometer, an MP3 player (Moving Picture Experts group Audio Layer III, motion Picture Experts compression standard Audio Layer 3), an MP4 player (Moving Picture expert Audio Layer IV, motion Picture Experts compression standard Audio Layer 3), a Personal Digital Assistant (PDA), a laptop computer, and the like.

2) The SIM card includes, but is not limited to, a SIM (Subscriber Identity Module) card, a UIM (User Identity Module) card, and a USIM (Universal Subscriber Identity Module) card.

3) The International Mobile Subscriber Identity (IMSI) is a mark for distinguishing a Mobile Subscriber, is stored in the SIM card, and can be used for distinguishing effective information of the Mobile Subscriber. The total length of the device does not exceed 15 bits, and numbers ranging from 0 to 9 are also used. The MCC is the code number of the country to which the mobile subscriber belongs, occupies 3 digits, and is specified as 460 in China; the MNC is a mobile network number and consists of two digits or three digits, and the Mobile Network Code (MNC) of China Mobile is 00; the mobile communication network is used for identifying the mobile communication network to which the mobile user belongs; MSIN is a mobile subscriber identity used to identify a mobile subscriber in a mobile communications network.

4) Global System for Mobile Communication (GSM) is currently the most widely used Mobile phone standard. More than 200 countries and regions worldwide are using GSM phones for more than 10 billion people. The ubiquity of the GSM standard makes international roaming of users commonplace after signing a "roaming agreement" between mobile phone operators. GSM differs from its previous standard most in that its signaling and voice channels are digital, and is therefore considered a second generation (2G) mobile telephone system. This illustrates that digital communication has long been built into systems. GSM is an open standard currently developed by 3 GPP.

5) Universal Mobile Telecommunications System (UMTS) is a complete 3G Mobile communications technology standard, and UMTS is not limited to defining air interfaces. In addition to the continued sophistication of WCDMA as the preferred air interface technology, the UMTS has also introduced TD-SCDMA and HSDPA technologies in succession.

6) The 4th Generation mobile communication standard (4G) refers to a fourth Generation mobile communication technology, which includes two systems of TD-LTE and FDD-LTE (LTE is only 3.9G in strict sense, and although advertised as a 4G wireless standard, it is not actually recognized by 3GPP as the next Generation wireless communication standard IMT-Advanced described by the international telecommunications union, and thus it has not yet reached the 4G standard in strict sense. Only the upgraded LTE Advanced meets the requirements of the international telecommunications union for 4G).

7) "plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Embodiments of the present application are described below with reference to the drawings.

In order to facilitate understanding of the embodiments of the present invention, a communication network architecture on which the embodiments of the present invention are based is described below. Referring to fig. 1, fig. 1 is a communication network architecture diagram provided in an embodiment of the present invention, where the network architecture includes a total network access terminal device and a plurality of base stations that provide communication service support for the total network access terminal device, and the base stations are provided by a plurality of operators respectively, so that a requirement that the total network access terminal device can support different network systems can be met. In fig. 1, services of multiple communication network systems provided by different base stations may include GSM, UTMS, eHRPD, LTE, and the like, and when the terminal device is a telecommunication terminal device, it mainly supports a CL mode; when the terminal equipment is mobile or connected terminal equipment, the GUL mode is mainly supported. Specifically, the CL mode may be understood as a mode in which the chinese telecommunication terminal device supports one of LTE access and CDMA access (e.g., eHRPD access), that is, one of 1X/HRPD access modes supported by the user configuring the terminal through an AT command syscfvex; the GUL mode can be understood as a mode that China Mobile and China Unicom terminal equipment supports one of GSM, UTMS and LTE, namely an access mode that a user configures the terminal by AT command SYSCFGEX and does not support 1X and HRPD.

It is to be understood that the base Station in the communication system in fig. 1 may be a Base Transceiver Station (BTS) in GSM or CDMA, a base Station (NodeB) in WCDMA, an evolved Node B (eNB or eNodeB) in LTE, or a base Station device in a future 5G network, and the like, which is not limited in this disclosure. In addition, the communication system may further include a core network device and the like, and the core network provides data support and related services for the communication process between the base station and the terminal device. It is understood that the above network architecture in fig. 1 is only one implementation manner in the embodiment of the present invention, and the network architecture in the embodiment of the present invention includes, but is not limited to, the above network architecture.

Referring to fig. 2, fig. 2 is a schematic flowchart of a network access processing method according to an embodiment of the present invention, and the network access processing method according to the embodiment of the present invention will be described in detail from the terminal device side with reference to fig. 2. As shown in fig. 2, the method may include the following steps S201 to S202.

Step S401: before the terminal equipment is started and registered, reading an International Mobile Subscriber Identity (IMSI) list stored in the terminal equipment.

Specifically, under normal conditions, the mobile phone will execute the following steps in sequence after being turned on: after the three processes are executed, the mobile phone is already attached to the mobile communication network, and normal service can be carried out. The PLMN selection is mainly to select a suitable PLMN according to the signal strength of the measured cell, and the cell selection is to select a suitable (non-restricted) cell according to the broadcast information of the cell and the IMSI information of the subscriber identity card, and to camp the mobile phone in the cell. After the mobile phone completes PLMN and cell selection, a location registration procedure is generally initiated, and the location of the mobile phone is reported to the mobile network, where the currently existing location registration procedure includes LAU (normal LAU/IMSI attach), GPRS attach, and EPS attach, and in a broad sense, RAU/TAU and other procedures also belong to the location registration procedure. In the registration process, the mobile communication network may also reject the registration of the mobile phone, and possible situations include that the current location area is unavailable, the current PLMN is unavailable, the mobile phone is illegal, the IMSI is illegal, and the like. If the registration fails, the mobile phone will reinitiate cell reselection, even PLMN reselection, etc. according to the reject cause value.

For the multimode terminal equipment supporting 4G, when a user identity identification card (such as a SIM card) of a user does not support 4G, when accessing an LTE network, the user is rejected by various cause values at the network side to move a user of a unified card, and a USIM card not signing 4G accesses LTE, and the user is rejected by the cause value of "# 7EPS service not allowed" at the network side, and for a user of a telecommunication card, the user is rejected by the cause value of "# 15No able cells in tracking area" at the network side. However, for a terminal device (a terminal device supporting multiple modes) which is connected to the whole network, it is currently preferred to try to access an LTE network, that is, after the terminal device is powered on, LTE is preferentially searched, which results in that for an SIM card which does not sign LTE, the SIM card is rejected by network test only when trying to access after searching for an LTE network. That is, the terminal device will try other system networks only after the SIM card fails to try to access the LTE. Therefore, when the terminal device needs to be powered on and registered each time, the time for acquiring the service is increased, so that the waiting time of the user is prolonged, and the user experience is seriously influenced.

In summary, for the card not subscribing to 4G, no matter in CL or gil mode, every time the user starts the phone, the user tries in LTE for a period of time, and then goes to try in other modes, which affects the time for the user to start the phone to obtain the service. In the embodiment of the invention, a target user identity identification card runs in terminal equipment, the terminal equipment supports a full network communication mode, the terminal equipment does not immediately perform network registration after being started, but reads an International Mobile Subscriber Identity (IMSI) list stored in the terminal equipment before starting registration, the IMSI list stores IMSI of the user identity identification card which does not support the LTE mode, and particularly stores the IMSI which does not support the LTE mode into a related list by which mode, the IMSI can be actively stored by a user; or the relevant IMSI information which does not support the LTE system and is provided by the operator when the SIM card is issued can be provided, so that the terminal equipment can download the IMSI information by the network; or whether all the user identification cards which are operated by the terminal device per se support the LTE system or not is recorded, and the like.

Step S402: and if the IMSI of the target user identity identification card is judged to be stored in the IMSI list, the terminal equipment is forbidden to search or try to access the LTE network.

Specifically, if the terminal device finds the IMSI of the currently operating subscriber identity card in the IMSI list stored in the terminal device, it may be determined that the currently multi-operating subscriber identity card does not support the LTE standard, and therefore if the current multi-operating subscriber identity card is preferentially searched or attempted to access the LTE network, time and resources may be wasted, and the power-on and network-access efficiency of the user is greatly affected. It can be understood that the target user identification card no-sign-on 4G is mainly in the following scenario:

a) the user does not change the 4G card or the 3G card, and the mobile phone supports 4G;

b) the user changes the 4G card into the non-activated 4G card, and the mobile phone supports 4G;

c) the user changes into a 4G card, the card is activated, the mobile phone supports local 4G, but the 4G is not opened when the mobile phone is accessed to other operators.

In a possible implementation manner, the determining whether the target user identity card supports an LTE standard includes: and judging whether the target user identity identification card supports the LTE system or not according to the LTE network access success response fed back by the network side or the rejection reason value of the LTE network for rejecting access. For a 4G-supporting multimode terminal, when receiving an access success response fed back by a network side, judging that a target user identity identification card operating in the terminal equipment supports an LTE system; for the multimode terminal supporting 4G, when all cards of the user do not support 4G, the network side rejects the LTE access with various cause values, taking a mobile or a unicom card user as an example, the USIM card not signing for 4G accesses the LTE access, the network side rejects with a cause value of "# 7 epservice not allowed" and the network side rejects with a cause value of "# 15 nosable cells in tracking area" for the telecom card user. The 3gpp 24301 protocol specifies that when TAU, ATTACH and SERVICE flows are performed under LTE, if the terminal is rejected by a network side with a #15 enable cells in tracking area cause value and carries an extension cause value, the terminal needs to forbid access to LTE for a period of time. The 3gpp 24301R13 protocol is explained for the case of ATTACH or TAU rejected #15 under LTE as follows: #15(No able cells interleaving area) (No available cell in the current tracking area); if the ATTACH REJECT message carries an extended cause value IE entry, and its value is "E-UTRAN not allowed", and in addition, the UE supports a "disable LTE rejected by #15 cause value" procedure, the UE shall behave as forbidden to access LTE and search for available cells in other systems. As can be seen from the above, for a terminal supporting 4G, when the terminal is rejected by the network side with the #15 cause value during access, if the terminal is required to prohibit LTE from trying other systems while carrying the extended cause value, it can be seen that, for the SIM card not signing 4G, the network side will notify the terminal with the above cause value.

Referring to fig. 3, fig. 3 is a schematic flowchart of another network access processing method according to an embodiment of the present invention. The network access processing method in the embodiment of the present invention will be described in detail below with reference to fig. 3 from the terminal device side. The method may comprise the following steps S301-S308.

Step S301: and when the target user identity identification card is inserted into the terminal equipment, judging whether the target user identity identification card supports an LTE system.

Specifically, the judging method may refer to the related description in the embodiment of fig. 2 for a detailed description according to the network access success response fed back by the network side or the rejection reason value for rejecting network access. Because there are various ways to judge whether the target user identity card supports the LTE network, the embodiment of the present invention adopts a way of judging by the terminal device itself. That is, when the target subscriber identity card is inserted into a certain all-network-connected terminal device for the first time, and when the target subscriber identity card does not support the LTE system, the IMSI of the card may not appear in the IMSI list, but after the first network access (LTE) is rejected, the IMSI of the card may be stored in the IMSI list after the card is determined to not support the LTE, so that the search or registration of the LTE network may be skipped when the network access registration is required again next time.

Step S302: and if not, writing the IMSI of the target user identity identification card into the IMSI list and storing the IMSI into the IMSI list.

Specifically, the IMSI list in the terminal device is used for the terminal device to know which subscriber identity cards do not support LTE, and then the IMSI corresponding to the subscriber identity card is stored in the IMSI list.

Step S303: and under the condition that the IMSI of the target user identity identification card is written and stored into the IMSI list, triggering a timer to be started for timing, wherein the timer is used for timing so that the terminal equipment is forbidden to search or attempt to access an LTE network only within the time period counted by the timer.

Specifically, under the condition that it is determined that the target user identity card does not support the LTE network, the corresponding IMSI is stored in the IMSI list, and meanwhile, a related timer is triggered to be started for timing, so that the timing is performed, and the terminal device is only prohibited from searching or attempting to access the LTE network within a time period timed by the timer. Namely, after a fixed time interval (timer is overtime), the function of searching or attempting to access the LTE network by the target subscriber identity card is reactivated, because, assuming that there is a misjudgment in the foregoing steps, that is, the target subscriber identity card is misjudged as not supporting LTE only because of poor current signal or poor network service state, or in some cases, the user activates the LTE function of the target subscriber identity card, if the LTE searching and accessing function of the target subscriber identity card is prohibited all the time, it may result in that the user cannot normally use the target subscriber identity card, therefore, at every fixed time interval, the LTE function of the target subscriber identity card is reactivated to allow the user to normally search for and attempt to access the LTE network, and if the network can be normally accessed, it is better to assume that the network cannot be accessed, the timer is started again, so that a large amount of network resources can be saved and the communication efficiency of the user is improved by the periodic circulation.

Step S304: before the terminal equipment is started to register, reading an International Mobile Subscriber Identity (IMSI) list stored in the terminal equipment, wherein a target user identity identification card runs in the terminal equipment, the terminal equipment supports a whole network communication mode, and the IMSI list stores IMSI of the user identity identification card which does not support a Long Term Evolution (LTE) mode.

Specifically, step S304 may refer to step S201 in the embodiment provided in fig. 2 correspondingly, and details of implementation are not described here again.

Step S305: and if the IMSI of the target user identity identification card is judged to be stored in the IMSI list and the timer is not overtime, the terminal equipment is forbidden to search or try to access the LTE network.

Specifically, the terminal device may be prohibited from searching or attempting to access the LTE network not only if the IMSI is present in the IMSI re-IMSI list, but also if the time counted by the started timer is not exceeded, that is, the timer is not expired.

Step S306: and when the timer is overtime, attempting to access the LTE network.

Specifically, if the timing time of the timer has been exceeded, the LTE network is attempted to be accessed according to the normal network access procedure.

Step S307: and if the LTE network is successfully accessed, removing the IMSI of the target user identity identification card from the IMSI list.

Specifically, if the target subscriber identity module card is successfully accessed to the LTE network at this time, it indicates that the card currently supports the 4G function, and removes the IMSI of the card from the IMSI list, so that the next time the registration process is started, the card may still search for a limited number of times or try to access the LTE network, that is, a normal network access process is implemented.

Step S308: and if the LTE network is failed to be accessed and the user identity identification card is judged not to support the LTE system, the timer is triggered again to start to time.

Specifically, if the target user identity card still fails to access the LTE network at this time, it indicates that the card still does not support the 4G function or does not activate the 4G function, obviously, the IMSI of the card is not cleared from the IMSI list, and the timer is triggered again to perform timing, so that the terminal device is prohibited from searching for or attempting to access the LTE network within the time period timed by the timer, and this is performed periodically.

In one possible implementation, the terminal device supports a GUL mode; the terminal device attempts to search for or access a global system for mobile communications GSM or universal mobile telecommunications system UMTS network after prohibiting the terminal device from searching for or attempting to access an LTE network.

In one possible implementation, the terminal device supports the CL mode; the terminal device attempts to search for or access a code division multiple access CDMA or evolved high speed packet network eHRPD network after prohibiting the terminal device from searching for or attempting to access an LTE network.

In a possible implementation, the IMSI list is stored in a non-volatile Flash memory NV Flash in the terminal device. That is, the IMSI list may be stored in a Flash space opened in a Non-Volatile Memory (Non-Volatile Memory) of the terminal device, so that the terminal device may be powered off or not powered off after writing the IMSI into the IMSI list.
