Description

Network residing method, electronic equipment and system

Technical Field

The present application relates to the field of communications, and in particular, to a network residence method, an electronic device, and a system.

Background

With the development of communication technology, the electronic device may not use a conventional physical Subscriber Identity Module (SIM), but use a virtual SIM card to enable the electronic device to access a mobile communication network, and perform normal operations such as call, short message, and internet access based on the network.

When the location of the user changes, the electronic device carried by the user may change the location area, move to a new area, and disconnect a Public Land Mobile Network (PLMN) of the original area. At this time, the electronic device may preferentially attempt to camp on a network corresponding to a PLMN identity in an equivalent public land mobile network (EHPLMN) list based on the virtual SIM card. However, because the EHPLMN list has limited capacity, if there is no PLMN in the current area in the list, the time consumed for the electronic device to camp on the network may be too long or the network camping may fail, resulting in a problem of low network camping efficiency.

Detailed Description

The technical solution in the embodiments of the present application will be described in detail and removed with reference to the accompanying drawings. In the description of the embodiments herein, "/" means "or" unless otherwise specified, for example, a/B may mean a or B; "and/or" in the text is only an association relationship describing an associated object, and means that three relationships may exist, for example, a and/or B may mean: three cases of a alone, a and B both, and B alone exist, and in addition, "a plurality" means two or more than two in the description of the embodiments of the present application.

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as implying or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of embodiments of this application, a "plurality" means two or more unless indicated otherwise.

First, a network residence process provided by the present application is introduced.

The electronic device may reside in a network of region 1, and when the electronic device detects that the region where the electronic device is located moves from region 1 to region 2, the electronic device may obtain, from the cloud server, the virtual SIM card applicable only to region 2. After receiving the virtual SIM card, the electronic device may write an identifier corresponding to a supported PLMN of the area 2 into the EHPLMN list, write an identifier corresponding to a non-supported PLMN of the area 2 into the FPLMN list, and then, the electronic device may reside on a network corresponding to a PLMN identifier in the EHPLMN list.

It can be seen from the above flow that, each time the electronic device detects that the electronic device moves to a new region, the virtual SIM card only applicable to the current region is obtained from the cloud server again, and network residence is performed again based on the virtual SIM card, so that the electronic device has a long time to reside in the network in the new region, and the network residence efficiency is low.

Therefore, the application provides a method for residing in a network. The electronic device may acquire PLMN information corresponding to the specified region and PLMN information corresponding to a relevant region of the specified region (e.g., a neighborhood of the specified region) from the cloud server. When the electronic equipment moves to a designated area, the electronic equipment can use the PLMN information of the designated area to complete the network residence. When the electronic equipment moves from the designated area to the relevant area of the designated area, the electronic equipment can use the PLMN information of the relevant area to complete network residence. The designated area and the relevant area of the designated area may be a country or some areas in the country.

Therefore, when the electronic equipment detects that the area where the electronic equipment is located changes, the cloud server does not need to issue the virtual SIM card again, resources of the virtual SIM card are saved, meanwhile, the time that the electronic equipment resides in a network of a new area can be shortened, and the network residing efficiency of the electronic equipment is greatly improved.

S306, the electronic device 100 stores the parameter information of the virtual SIM card 1.

Specifically, the electronic device 100 may save the parameter information of the virtual SIM card 1 in a secure execution area (TA) of a specified application (e.g., a hua-shi skynebanking application) in a Trusted Execution Environment (TEE) based on data security considerations. The TA can protect the confidentiality and integrity of the virtual SIM card 1 parameter information.

S307, the electronic device 100 stores the supported PLMN in use area 1 (which may also be referred to as first supported PLMN information) and the supported PLMN id in the use area 1 corresponding to the relevant area in EHPLMN list 1 (which may also be referred to as first EHPLMN list), and stores the non-supported PLMN in use area 1 and the non-supported PLMN in the use area 1 corresponding to the relevant area in FPLMN list 1.

Specifically, taking thailand (which may also be referred to as using region 1) as an example, the cloud server 200 may transmit PLMN information of a corresponding relevant region (e.g., a neighborhood of thailand) of thailand in the virtual SIM card 1 to the electronic device 100 based on a format of the following code:

wherein the first "MCC" in the code indicates the MCC code of thailand and "520" indicates the value of the MCC code of thailand. The 'neighbourInfo' mark indicates that the code area after the mark comprises the value '457' of the MCC code of Laos in the neighborhood of Thailand, the PLMN information of Laos, the value '414' of the MCC code of Burma in the neighborhood, and the PLMN information of Burma.

The cloud server 200 may transmit PLMN information of a neighborhood of burmar, PLMN information of a neighborhood of laos, and PLMN information of a neighborhood of india to the electronic device 100 in the above-described code format.

In one possible implementation manner, the cloud server 200 may also send PLMN information of each usage area neighboring area to the electronic device 100 based on other formats, which is not limited in this application.

The electronic apparatus 100 may preferentially store the supported PLMNs of the usage area 1 (for example, thailand) in the EHPLMN list 1 and the non-supported PLMNs of the usage area 1 in the FPLMN list 1 based on the parameter information (for example, the supported PLMNs and the non-supported PLMNs of each usage area in table 2) sent to the virtual SIM card 1 of the electronic apparatus 100 by the cloud server 200 in the foregoing step S305, and when the capacity (for example, 16) of the EHPLMN list 1 and the capacity (for example, 36) of the FPLMN list 1 are not reached, the electronic apparatus 100 may write the supported PLMNs of the relevant area (for example, laos) corresponding to the usage area 1 in the EHPLMN list 1 and write the non-supported PLMNs of the relevant area (for example, laos and myma) corresponding to the usage area 1 in the FPLMN list 1. The electronic device 100 may then store the EHPLMN list 1 and the FPLMN list 1 in the TA.

Here, taking the use area 1 as thailand as an example, the EHPLMN list 1 may be shown in table 4, and the FPLMN list 1 may be shown in table 5:

				45711	45712	45713	45714

In the table, "52001", "52002", "52003", "52004", "52011", "52012", "52013" and "52014" are identifiers of support PLMNs in thailand. "45701", "45702", "45703", "45704", "45711", "45712", "45713", "45714" is an identification of a Laos-enabled PLMN.

Wherein, "52005", "52006", "52007", "52008", "52009", "52010", "52015", "52016", "52017", "52018", "52019", "52020" in the table is an identifier of a non-supported PLMN in thailand. "45705", "45706", "45707", "45708", "45709", "45710", "45715", "45716", "45717", "45718", "45719", "45720" are the identities of the non-supported PLMNs of Laos. "41405", "41406", "41407", "41408", "41409", "41410", "41415", "41416", "41417", "41418", "41419", "41420" are the identities of the non-supporting PLMNs of Burma.

It should be noted that the above tables 4 and 5 are only used for illustrating the present application and should not be construed as limiting the present application.

In one possible implementation, the cloud server 200 may transmit MCC codes of each usage region and each usage region corresponding to the relevant region (e.g., the neighboring region of each usage region) to the electronic device 100, as shown in table 6:

TABLE 6

The country corresponding to the MCC code value "520" is thailand, and the MCC codes in the neighboring areas may be 457 (laos) and 414 (burma). The MCC code value "457" corresponds to a country that is Laos and adjacent MCC codes that may be 520 (Thailand) and 414 (Burma). The country corresponding to the MCC code "414" is Mymar, and the MCC codes in the neighborhood can be 520 (Thailand), 457 (Laos) and 405 (India). The country corresponding to the MCC code value "405" is india and the MCC code in its neighborhood may be 414 (macadam).

The electronic device 100 may query the supported PLMNs and the non-supported PLMNs corresponding to the MCC codes of the usage regions and the relevant regions corresponding to the usage regions (e.g., the neighborhoods of the usage regions) from table 2 based on the MCC codes of the usage regions and the MCC codes of the relevant regions corresponding to the usage regions (e.g., the neighborhoods of the usage regions) in table 6. Then, the electronic apparatus 100 may write the supported PLMNs of the respective use areas and the respective relevant areas corresponding to the respective use areas (e.g., the vicinity of the respective use areas) into the EHPLMN list 1, and write the non-supported PLMNs of the respective use areas and the relevant areas corresponding to the respective use areas (e.g., the vicinity of the respective use areas) into the FPLMN list 1. This is not limited by the present application.

It should be noted that table 6 is only used for illustrating the present application and should not be construed as limiting the present application.

In one possible implementation manner, the electronic device 100 may receive coordinate information corresponding to MCC codes of respective usage regions sent by the cloud server 200. When the electronic device 100 acquires the value of the MCC code of the designated use area and reaches the use area, the electronic device 100 may determine the MCC code of the relevant area of the use area (e.g., the vicinity of the use area determined by the electronic device 100) based on a preset condition (e.g., the distance from the use area is at a designated threshold). Then, the electronic device 100 may obtain the supported PLMN and the non-supported PLMN of the relevant area corresponding to the specified area based on the obtained MCC code of the relevant area corresponding to the specified area. Electronic device 100 may write the supported PLMN to EHPLMN list 1 and the non-supported PLMN to FPLMN list 1.

S308, the electronic device 100 resides in the use area 1 based on the EHPLMN list 1.

Specifically, the electronic device 100 may select a suitable PLMN according to a designated priority order (for example, according to a sequence order arranged in the list) based on the EHPLMN list 1, and then the electronic device 100 camps on the mobile network in the use area 1 based on the selected PLMN.

Specifically, the selected PLMN may include a plurality of areas, and each area may be referred to as a cell (cell). The electronic device 100 may determine a suitable cell (e.g., the cell with the strongest signal in the frequency band) based on the selected PLMN. The electronic device 100 may perform data interaction with a network in which the cell is located, so that the electronic device 100 may camp on the network corresponding to the cell.

For example, taking the use area 1 being thailand as an example, the electronic device 100 may select, based on the EHPLMN list 1, a supported PLMN corresponding to the supported PLMN identifier "52001" with the highest priority and the top ranking order according to the ranking order in the list. The electronic device 100 may then determine a suitable cell (e.g., the cell with the strongest signal in the frequency band) based on the selected supported PLMN to camp on the supported PLMN.

S309, when the electronic device 100 detects that the electronic device 100 moves to the use area 2 (may also be referred to as a third area), the electronic device 100 may camp on to the use area 2 based on the EHPLMN list 1.

Specifically, the use area 2 is a relevant area of the use area 1 (for example, the use area 2 is adjacent to the use area 1), and in the step S307, the supported PLMN (which may also be referred to as third supported PLMN information) of the use area 2 is already stored in the EHPLMN list 1, and the non-supported PLMN of the use area 2 is already stored in the FPLMN list 1. When the electronic device 100 detects that the electronic device 100 moves to the usage area 2 (for example, the electronic device 100 may acquire the MCC code value from the searched PLMN, where the MCC code value is the MCC code value corresponding to the usage area 2), the electronic device 100 may select a suitable PLMN from the EHPLMN list 1 according to a specified priority order (for example, according to a sequence arranged in the EHPLMN list 1) to search, and camp in the usage area 2. The network-residing procedure may be parameterized by the aforementioned step S308, and will not be described herein again.

For example, usage area 2 may be Laos, and the MCC code for Laos may be "457". When the electronic device 100 detects one or more PLMNs, the MCC code of the one or more PLMNs has a value of "457", and the MCC code has a value different from the MCC code of the PLMN where the electronic device 100 resides before "520", the electronic device 100 may determine that the electronic device 100 has moved to a new region. The electronic device 100 may select, from the EHPLMN list 1 according to the sequential order of the MCC code value "457", a PLMN "45701" with the MCC code value "457" and the most advanced sequential order, where the PLMN "45701" may include a plurality of regions, and each region may be referred to as a cell (cell). The electronic device 100 may determine a suitable cell (e.g., the cell with the strongest signal in the frequency band) based on the PLMN "45701". The electronic device 100 may perform data interaction with a network in which the cell is located, so that the electronic device 100 may camp on the network corresponding to the cell.

S310, when the electronic device 100 detects that the electronic device 100 moves to the use region 3 (which may also be referred to as a second region) and no PLMN in the use region 3 is supported in the EHPLMN list 1, the electronic device 100 camps on the searched PLMN (which may also be referred to as a first PLMN).

Specifically, the use area 3 is a relevant area of the use area 2 (for example, the use area 3 is adjacent to the use area 2). When the electronic device 100 detects that the electronic device 100 moves to the usage area 3 (for example, the electronic device 100 may acquire the value of the MCC code from the searched PLMN, and the value of the MCC code uses the value of the MCC code corresponding to the usage area 3), since the capacity of the EHPLMN list 1 is limited, the supported PLMN of the usage area 3 is not stored in the foregoing step S307, and the supported PLMN of the usage area 3 is not stored in the EHPLMN list 1, so that the electronic device 100 cannot camp on the EHPLMN list 1. At this time, the electronic device 100 may exclude the non-supported PLMNs of the use area 3 stored in the FPLMN table based on the searched PLMNs, and then the electronic device 100 may select a suitable PLMN (e.g., the PLMN with the strongest signal) from the remaining searched PLMNs and select a suitable cell (e.g., the cell with the strongest signal in the frequency band) based on the PLMN. The electronic device 100 may perform data interaction with the network in which the cell is located, so as to camp on the network corresponding to the cell.

For example, region of use 3 may be Mymar, and the MCC code of Mymar may have a value of "414". When the electronic device 100 detects one or more PLMNs, the MCC code of the one or more PLMNs has a value of "414", and the MCC code has a value different from the value "457" of the MCC code of the PLMN where the electronic device 100 resides, the electronic device 100 may determine that the electronic device 100 has moved to a new region. The electronic device 100 cannot query the EHPLMN list 1 for a PLMN having an MCC code value of "414". Therefore, the electronic device 100 may exclude the non-supported PLMNs "41405" to "41410" and "41415" to "41420" having the MCC code value of "414" stored in the FPLMN table based on the searched PLMNs, and then the electronic device 100 may select the PLMN "41421" having the strongest signal from the remaining searched PLMNs and select the cell having the strongest signal in the frequency band based on the PLMN. The electronic device 100 may perform data interaction with the network in which the cell is located, so as to camp on the network corresponding to the cell.

S311, based on the parameter information of the virtual SIM card 1, when the electronic device 100 confirms that the PLMN residing in step 310 is not the supported PLMN of the use area 3, updating the EHPLMN list 1 and the FPLMN list 1, and obtaining an EHPLMN list 2 (which may also be referred to as a second EHPLMN list) and an FPLMN list 2.

Specifically, after the electronic device 100 receives the instruction of successful network camping, the electronic device 100 may determine whether the PLMN hosted by the electronic device 100 in step 310 is the supported PLMN of the usage area 3 based on the parameter information (for example, the supported PLMNs of the usage areas and the supported PLMNs of the relevant usage areas) of the virtual SIM card 1 stored in the TA. When the electronic device 100 confirms that the PLMN is not a supported PLMN for use region 3, the electronic device 100 updates EHPLMN list 1 and FPLMN list 1 to obtain EHPLMN list 2 and FPLMN list 2.

When the electronic device 100 updates the EHPLMN list 1 and the FPLMN list 1, the electronic device 100 may preferentially store the supported PLMNs (also may be referred to as second supported PLMN information) using the region 3 (e.g., from mamar) in the EHPLMN list 1, store the non-supported PLMNs using the region 3 (e.g., from mamar) in the FPLMN list 1, when a capacity (e.g., 16) of the EHPLMN list 1 and a capacity (e.g., 36) of the FPLMN list 1 are not reached, the electronic device 100 may store the supported PLMNs using the region 3 neighboring region (e.g., india) in the EHPLMN list 1, store the non-supported PLMNs using the region 3 neighboring region (e.g., india and thailand) in the FPLMN list 1, and obtain the EHPLMN list 2 and the FPLMN list 2. The electronic device 100 may then store the EHPLMN list 2 and the FPLMN list 2 in the TA. In this process, the electronic device 100 disconnects from the PLMN where the step S310 resides.

For example, taking Burma as an example of using region 3, the EHPLMN list 2 may be shown in Table 7, and the FPLMN list 2 may be shown in Table 8:

TABLE 7

41401	41402	41403	41404
				41411	41412	41413	41414

				40511	40512	405013	405014

Wherein "41401", "41402", "41403", "41404", "41411", "41412", "41413" and "41414" in the table are the identities of the supporting PLMNs of burma. "40501", "40502", "40503", "40504", "40511", "40512", "40513" and "40514" are indian identifiers of supported PLMNs.

Wherein "41405", "41406", "41407", "41408", "41409", "41410", "41415", "41416", "41417", "41418", "41419" and "41420" in the table are the identities of the non-supporting PLMNs of Burma. "40505", "40506", "40507", "40508", "40509", "40510", "40515", "40516", "40517", "40518", "40519", "40520" are the indian identification of non-supported PLMNs. "52005", "52006", "52007", "52008", "52009", "52010", "52015", "52016", "52017", "52018", "52019", "52020" is an identifier of a non-supported PLMN in thailand.

S312, the electronic device 100 relocates to the use area 3 based on the PLMNs in the EHPLMN list 2.

Specifically, the electronic device 100 may perform network camping again based on the EHPLMN list 2 in step S311. The step S308 may be referred to in the network residence process, and is not described herein again.

For example, burma is taken as an example of the usage area 3. The electronic device 100 has resided in the exemplary PLMN "41421" shown in step 311 above. When the electronic device 100 detects that the PLMN "41421" is not a supported PLMN of burma based on the parameter information of the virtual SIM card 1 already stored in the TA, the electronic device 100 may update the EHPLMN list 1 and the FPLMN list 1 as described in the previous step S311, obtain the EHPLMN list 2 and the FPLMN list 2, and disconnect from the PLMN "41421". The electronic device 100 may re-camp to burma based on the EHPLMN list 2 (e.g., table 7). The network residence process may refer to the aforementioned step S308, which is not described herein again.

In some embodiments, after the electronic device 100 resumes the network camping based on the EHPLMN list 2 in step S312 and successfully camps on the network, the electronic device 100 may display a notification message (which may also be referred to as a second notification message) indicating that the network camping is successful in the use area 3.

In some embodiments, when the electronic device 100 detects that the PLMN residing in step 311 is a supported PLMN for use in region 3 (e.g., burma), on which the electronic device 100 may continue to reside, the electronic device 100 may display a notification of successful network residing for notifying the user of successful network residing in region 3.

In some embodiments, when the electronic device 100 performs network camping based on the EHPLMN list 1 in the use area 1, and successfully camps on the network, the electronic device 100 may display a network camping success notification message (which may also be referred to as a first notification message) to prompt the user that network camping is successful in the use area 1.

In some embodiments, when the electronic device 100 camps on the network in the usage area 2 based on the EHPLMN list 1, after successfully camping on the network, the electronic device 100 may display a notification message (which may also be referred to as a third notification message) indicating that network camping is successful in the usage area 2, so as to prompt the user that network camping is successful in the usage area 2.

In some embodiments, when the electronic device 100 detects that the PLMN residing in step 311 is a supported PLMN using region 3 (e.g., burma), the electronic device 100 may continue to reside on the PLMN.

In some embodiments, usage zone 3 may not be a corresponding relevant region of usage zone 1 (e.g., usage zone 3 is not a neighborhood of usage zone 1). Therefore, in step S307, EHPLMN list 1 does not use the supported PLMN information of region 3. When the electronic apparatus 100 reaches the use area 3, the aforementioned steps S310 to S311 may be executed.

In some embodiments, electronic device 100 may detect that electronic device 100 has moved to use region 2 or use region 3 by other means. For example, the electronic device 100 may acquire current coordinate information of the electronic device 100 through a Global Navigation Satellite System (GNSS), and the electronic device 100 may detect that the electronic device 100 has moved to the use area 2 or the use area 3 based on the coordinate information and map data stored in the electronic device 100. This is not limited by the present application.
