All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The terms first, second and the like in the description and in the claims and in the above-described figures are used for distinguishing between different objects and not necessarily for describing a sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may 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 may be included in at least one embodiment of the application. The appearances of such phrases 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. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

The following description will first be made of the relevant terms that the present application relates to.

Subscriber identity card (Subscriber Identity Module, SIM): is an integrated circuit card held by a mobile subscriber of the global system for mobile communications (Global System for Mobile Communications, GSM) system, which enables the handset to connect to the global system for mobile communications network and enjoy various services provided by the network operator.

Dual card dual standby single pass (Dual Sim Dual Standby, DSDS): the mobile phone is provided with two user identification cards, and the two cards are kept in a standby state at the same time, but when one card is in a call state, all radio frequency resources of the mobile phone are completely exclusive, and the other card can only be disconnected and can not answer an incoming call.

Double-card double-standby double pass (Dual SIM Dual Active, DSDA): the mobile phone is provided with two user identification cards, and the two cards are kept in a standby state at the same time. When one card is in a call state, the other card network is kept connected continuously, and can make and receive calls.

User Equipment/terminal (UE): in 3G and 4G networks, a user terminal is called UE, and the UE in the 3G network corresponds to an MS in the 2G network and includes a mobile phone, an intelligent terminal, a multimedia device, a streaming media device, and so on.

Long term evolution technology (Long Term Evolution, LTE): is the evolution of 3G, is a transition between 3G and 4G technologies, and is a global standard for wireless data transmission by fourth-generation mobile network technology.

New air interface (NR): is mainly applied to the 5G field and is called 5G NR. The 5G NR is based on a global 5G standard of completely new air interface design of orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM).

The new air interface carries speech (Voice over New Radio, voNR): the voice service based on 5G is that the NR user can directly perform the voice service based on the NR network without falling back to the LTE network, so that higher-quality voice service experience and higher-rate data service experience are obtained. Before the application of the VoNR technology, the voice call can enable the mobile phone resident network to fall back from 5G to 4G, but the VoNR technology supports the concurrency of 5G data and voice.

Physical cell identity (Physical Cell Identifier, PCI): the terminal in LTE distinguishes the wireless signals of different cells by the method, and ensures that the same physical cell identification does not exist in the coverage range of the related cells.

Carrier frequency point number (E-UTRA Absolute Radio Frequency Channel Number, EARFCN): the absolute radio frequency channel number, i.e. the channel number corresponding to the carrier frequency used for mobile communication.

Tracking Area (TA): the tracking area is a new concept set up by the LTE system for location management of UEs, and is defined as a free mobile area where the UEs do not need to update location services. The UE informs the 4G mobile communication network core network (Evolved Packet Core, EPC) of own tracking area through the tracking area registration, when the UE is in an idle state, the core network can know the tracking area of the UE, and when the UE in the idle state needs to be paged, paging is required to be carried out on all cells of the tracking area registered by the UE. The TA is a configuration at a cell level, a plurality of cells can configure the same TA, and one cell can belong to only one TA.

Tracking area update request (Tracking area update request, TAU): when the position of the UE changes (i.e. the UE enters a new TA and its tracking area identifier is not in the tracking area list stored in the UE), the network side needs to be notified of the position update by a corresponding procedure (i.e. TAU) to register new user position information, otherwise, the network side cannot acquire the correct position of the UE, which results in paging failure.

In order to better understand the technical solutions of the embodiments of the present application, the following describes electronic devices that may be related to the embodiments of the present application.

Referring to fig. 1, fig. 1 is a block diagram of an electronic device according to an embodiment of the present application. As shown in fig. 1, the electronic device 100 may implement steps in a network searching control method, where the electronic device 100 includes a processor 110, a memory 120, a communication interface 130, and one or more programs 121, where the one or more programs 121 are stored in the memory 120 and configured to be executed by the processor 110, and the one or more programs 121 include instructions for performing any of the steps in the method embodiments described above.

The communication interface may also be a transceiver, a transceiver circuit, etc. for supporting communication between the first electronic device and other devices. The memory is used for storing program codes and data of the terminal. The processor may also be a controller, such as a central processing unit (Central Processing Unit, CPU), a general purpose processor, a digital signal processor (Digital Signal Processor, DSP), an Application-specific integrated circuit (ASIC), a field programmable gate array (Field Programmable Gate Array, FPGA) or other programmable logic device, transistor logic device, hardware component, or any combination thereof. Which may implement or perform the various exemplary logic blocks, units and circuits described in connection with this disclosure. The processor may also be a combination that performs the function of a computation, e.g., a combination comprising one or more microprocessors, a combination of a DSP and a microprocessor, and the like.

The memory may be volatile memory or nonvolatile memory, or may include both volatile and nonvolatile memory. The nonvolatile memory may be a read-only memory (ROM), a Programmable ROM (PROM), an Erasable PROM (EPROM), an electrically Erasable EPROM (EEPROM), or a flash memory. The volatile memory may be random access memory (random access memory, RAM) which acts as an external cache. By way of example but not limitation, many forms of random access memory (random access memory, RAM) are available, such as Static RAM (SRAM), dynamic Random Access Memory (DRAM), synchronous Dynamic Random Access Memory (SDRAM), double data rate synchronous dynamic random access memory (DDR SDRAM), enhanced Synchronous Dynamic Random Access Memory (ESDRAM), synchronous Link DRAM (SLDRAM), and direct memory bus RAM (DR RAM).

In a specific implementation, the processor is configured to perform any step performed by the electronic device in the above method embodiment, and when performing data transmission such as sending, the communication interface is optionally invoked to complete a corresponding operation.

Currently, a dual-card type communication device may implement DSDA functions, so that a user may implement simultaneous use of multiple SIM cards without carrying multiple communication devices. However, the communication device can only support the DSDA function under the specific scenario, so that the network searching operation started by the subscriber identity module card of the non-executing service in the dual card under the non-specific scenario may take time and occupy the antenna radio frequency resource of the communication device, thereby causing that the subscriber identity module card of the executing service cannot normally perform the service, and making the user experience worse.

In order to solve the above-mentioned problems, the embodiments of the present application provide a method for controlling search and a related device, where the method is applied to an electronic device, the electronic device includes a first subscriber identity card and a second subscriber identity card, and the electronic device supports a dual-card dual-standby dual-pass function based on the first subscriber identity card and the second subscriber identity card. The method comprises the steps of obtaining a reference working frequency band of a first user identification card in a language service state and a double-channel frequency band set of a double-card double-channel function supported by electronic equipment, and judging that a target double-channel frequency band group containing the reference working frequency band can be inquired in the double-channel frequency band set, so that a second user identification card is controlled to reside in a target service cell based on a frequency band in the target double-channel frequency band group to support the double-card double-channel function of the electronic equipment. Therefore, the electronic equipment can avoid invalid network searching operation without the adaptive candidate working frequency band, reduces network searching complexity relative to the global network searching, and improves network searching success rate and efficiency.

The following describes the process of the network searching control method according to the embodiment of the present application from the perspective of the method embodiment.

Referring to fig. 2a, fig. 2a is a schematic process diagram of a network searching control method according to an embodiment of the present application, where the method includes the following steps:

step 2a01, acquiring a reference working frequency band of a first user identification card of the electronic equipment;

the electronic equipment supports a double-card double-pass function based on the first user identification card and the second user identification card;

alternatively, the network-resident mode of the dual card dual-pass function supported by the electronic device may be "dual 4G", "5g+4g", "3g+4g", or the like. Taking a combination of two SIM cards of the electronic device as a new wireless network residence mode and a long-term evolution network residence mode (i.e. "5g+4g"), in the network residence mode, when the electronic device can support DSDA on the N41+b3 band (N41 is the 5G band and B3 is the 4G band), after the SIM card of the new wireless network residence mode (i.e. card 1) has connected to the VoNR voice service on the N41 band (when the electronic device is in the DSDS mode), the SIM card of the long-term evolution network residence mode (i.e. card 2) preferentially tries to search for an LTE cell that can be combined with the N41 band of card 1 and support DSDA (when the electronic device is in the DSDS mode). When card 2 searches B3 cell (EARFCN 1300, PCI 196) because the electronic device is a band combination supporting n41+b3, card 2 will reside in B3 cell, at which time the electronic device has completed the DSDS mode switch to DSDA mode and card 1 can conduct VoNR call normally. The information processing process of the electronic device corresponding to the application scene is shown in table 1:

Table 1 information processing procedure of electronic device

Step 2a02, obtaining a double-pass frequency band set;

the double-pass frequency band set comprises at least one double-pass frequency band group, wherein a single double-pass frequency band group comprises a first type of working frequency band of a first user identification card supporting a double-card double-pass function and a second type of working frequency band of a second user identification card, and the working frequency bands in any two double-pass frequency band groups are different;

the timing of step 2a01 and step 2a02 is not limited to the same, and may be the first step 2a01 and then step 2a02, or may be the first step 2a02 and then step 2a01, or may be executed simultaneously.

Optionally, taking the combination of the network modes of the two SIM cards of the electronic device as a new wireless network mode (i.e. a 5G network mode) and a long-term playing network mode (i.e. a 4G network mode) as an example, currently, the mainly used 5G frequency bands in China have N1, N3, N28, N41, N77, etc., and the mainly used 4G frequency bands have B1, B3, B5, B8, B34, etc., and the network mode of the first subscriber identity module card is assumed to be the 5G network mode. The first type of operating frequency band of the first subscriber identity card supported By the electronic device with the dual-card dual-pass function may be denoted as Nx (where Nx is a certain frequency band existing currently), the second type of operating frequency band of the second subscriber identity card may be denoted as By (where By is a certain frequency band existing currently), and the single dual-pass frequency band group may be denoted as (Nx, by) to characterize the electronic device to support the DSDA function of the first subscriber identity card in the frequency band combination of Nx operating frequency band and the second subscriber identity card in the By operating frequency band, where the electronic device may implement the DSDA mode switching.

Optionally, a dual-card dual-pass detection module (the module should be functionally divided) is disposed in the electronic device to obtain and determine whether the electronic device includes a dual-pass band set, refer to fig. 2b, and fig. 2b is a schematic flow diagram of the dual-card dual-pass detection module according to the embodiment of the present application, as shown in fig. 2b, the flow is as follows:

step 2b01: and reading the radio frequency configuration of the electronic equipment.

The module is used for reading the radio frequency configuration of the electronic equipment, so that a detection result is obtained. According to whether the radio frequency configuration contains the double-pass band set or not, the detection result is divided into success and failure, if the radio frequency configuration contains the double-pass band set, the detection result is success; if the dual-channel set is not included, the detection result is failure.

Step 2b02: if the detection result is successful, returning to the dual-channel set, and if the detection result is failed, returning to a failure instruction.

Optionally, by setting a dual-card dual-pass detection module, the network searching control method of the present application may also be implemented, referring to fig. 2c, fig. 2c is a schematic flow chart of dual-card dual-pass detection provided by the embodiment of the present application, as shown in fig. 2c, the flow chart is as follows:

step 2c01, detecting that the electronic device performs a call service (i.e. one of the SIM cards is in a voice service state), and entering step 2c02.

Step 2c02, entering a detection flow of the double-card double-pass detection module, and entering step 2c03 or directly entering step 2c05 according to a detection result.

The entering into different steps according to the detection result specifically comprises three conditions: the first case is that the detection result is successful, the double-pass band set is returned, and the target double-pass band set containing the working band of the SIM card in the voice service state can be queried in the double-pass band set, and in this case, step 2c03 is entered; the second case is that the detection result is successful, and the dual-pass band set is returned, but the target dual-pass band set containing the working band of the SIM card in the voice service state cannot be queried in the dual-pass band set, and in this case, step 2c05 is entered; the third case is that the detection result is failure, and a failure instruction is returned, and the process proceeds directly to step 2c05.

Step 2c03, starting a network searching process (aiming at another SIM card), and entering step 2c04 after searching the target cell.

The network searching process is performed on another SIM card which is not in a voice call state, and the searched frequency band is determined according to the second type of working frequency band in the target double-pass frequency band group, so that the searched frequency band can be ensured to support the electronic equipment to be switched to the DSDA mode.

Step 2c04, camping on the target cell, and proceeding to step 2c05.

After the electronic equipment resides in the target cell, the electronic equipment can select to start a tracking area position updating process in the cell according to actual conditions, so that the network equipment can record a new position updated by the electronic equipment in time, and the electronic equipment can be normally paged.

Step 2c05, maintaining the subsequent call.

In one possible embodiment, after the acquiring the two-pass band set, the method further includes:

and if the double-pass band group containing the reference working band is not inquired in the at least one double-pass band group, maintaining the current working band of the second user identification card.

The method does not change the working frequency band of the first user identification card, but only the working frequency band of the second user identification card. And whether the working frequency band of the second subscriber identity card needs to be changed is related to whether at least one double-pass frequency band group can inquire the double-pass frequency band group containing the reference working frequency band, if not, the fact that the reference working frequency band where the current first subscriber identity card is located is combined with any working frequency band of the second subscriber identity card can not enable the electronic equipment to realize the double-card double-pass function is indicated, and the electronic equipment does not need to control the second subscriber identity card to start subsequent network searching operation, so that the current working frequency band of the second subscriber identity card can be kept under the condition.

For example, in the specific application scenario of the prior art, the reference operating frequency band of the first subscriber identity card (i.e. the card 1) may be changed, for example, the electronic device enters the N28 cell, and the operating frequency band of the SIM1 is switched from N41 to N28. At this time, a two-channel set of the electronic device is obtained, wherein the two-channel sets supported By the electronic device include (N41, B3), (N41, B1), and neither of the two-channel sets includes the reference operating frequency band N28, which means that any combination of n28+by is not a frequency band combination that the electronic device can support the dual-card two-channel function. However, the second subscriber identity card (i.e. card 2) still performs cell search operation, traverses various frequency bands of LTE, such as frequency bands B3, B39, B40, etc., and since the electronic device cannot support dual-card dual-pass of N28, card 2 cannot reside on the LTE cell. For the application scenario that the reference working frequency band of the card 1 is switched to the working frequency band of the electronic device which does not support the DSDA function, the information processing procedure of the electronic device is shown in table 2:

table 2 information processing procedure of electronic device

Referring to table 3, table 3 is a data receiving process of the electronic device, as shown in table 3, in the scenario of the prior art, the current mobile phone is in DSDS mode, the SIM1 and the SIM2 use radio frequency resources of the electronic device in a time-sharing manner, and the operation of searching for LTE of the SIM2 occupies antenna radio frequency resources, and because of too many frequency bands and incapacity of residing, the SIM1 can receive discontinuous video packets in a part of time in executing a call service, thereby causing data missing, call interruption or abnormal situations such as blurring or mosaic of video call images, and poor user experience.

Table 3 data receiving procedure of electronic device

The present application does not avoid the above situation, and determines whether to perform the network searching operation of the second subscriber identity module card and the subsequent procedure through the query step, if the two-way frequency band group including the reference working frequency band cannot be queried (i.e. the electronic device does not support DSDA of the reference working frequency band), no meaningless network searching operation is required, and only the working frequency band of the second subscriber identity module card needs to be maintained.

It can be seen that in this example, for the case of the working frequency band of the second subscriber identity card not adapting to the voice service frequency band of the first subscriber identity card, the network searching operation for the second subscriber identity card and the subsequent cell-camping procedure will not be triggered any more. Therefore, invalid network searching operation can be avoided, power consumption is reduced, and stability and resource utilization rate are improved.

In one possible embodiment, after said maintaining the current operating frequency band of the second subscriber identity card, the method further comprises: after the first user identification card exits the voice service state, monitoring a first network state of the current environment of the first user identification card and a second network state of the current environment of the second user identification card; and confirming the first user identification card or the second user identification card as a target user identification card according to the first network state and the second network state.

The target user identification card is used for accessing a corresponding network to provide data service for the electronic equipment.

Alternatively, this embodiment may occur after the electronic device controls the second subscriber identity card to camp on the target serving cell to support the dual card dual pass function. The network status may be a variety of information that can reflect current network performance, and may include, for example, network response time, network delivery time, network stability, and network speed. The target user identification card is confirmed according to the first network state and the second network state, and obviously, the user identification card with better network state in the current environment is confirmed to be used as the target user identification card, so that more excellent data service is provided for the electronic equipment.

It can be seen that, in this example, the selection step of the data service card is added in the dual-card dual-standby state of the electronic device. Therefore, after the voice service state of the first user identification card is finished, the electronic equipment can automatically use the user identification card with better network state as the data service card, so that the subsequent use experience of the user is improved and the stability is improved.

Step 2a03, if a target dual-channel band group containing a reference working frequency band is queried in the dual-channel band set, controlling the second subscriber identity card to reside in a target service cell so as to support a dual-card dual-channel function;

The target service cell is a service cell of a target working frequency band in a second class of working frequency bands of the target double-pass frequency band group.

In one possible embodiment, the controlling the second subscriber identity card to camp on a target serving cell to support the dual card dual pass function includes: performing cell search operation in a second class of working frequency band of the target double-pass frequency band group to obtain at least one candidate service cell; determining a target serving cell for camping on the network from the at least one candidate serving cell; camping on the target serving cell.

And controlling the second user identification card to execute cell search operation in a second type of working frequency band of the target double-pass frequency band group to obtain cells with frequency bands conforming to the second type of working frequency bands, wherein the cells are candidate service cells, and determining a target service cell for the second user identification card to reside in the network finally so as to realize the residence of the second user identification card and enable the second user identification card to be accessed to the network.

The determined target two-way frequency band groups are (N41, B3), (N41, B1), and the second type of working frequency band includes B3 and B1, and when the network searching operation is performed, only the frequency bands of B1 and B3 need to be searched for cells, so as to obtain a plurality of candidate serving cells, and then the target serving cells are determined through specific screening conditions, so that the second subscriber identity module card resides.

It can be seen that in this example, the cell network searching process for the second subscriber identity card is constrained by the target two-way band group including the first subscriber identity card, so that the network searching complexity is reduced and the network searching success rate and efficiency are improved relative to the global network searching in the prior art.

In one possible embodiment, the controlling the second subscriber identity card to camp on a target serving cell to support the dual card dual pass function includes: searching a second class of working frequency bands of the target double-pass frequency band group according to the historical network residence record of the second user identification card, and obtaining at least one candidate serving cell of which the frequency bands belong to the second class of working frequency bands; determining a target serving cell for camping on the network from the at least one candidate serving cell; camping on the target serving cell.

When the electronic device stores the historical network residence record, the candidate serving cells meeting the conditions can be directly searched in the historical network residence record, and the target serving cell for network residence is selected, so that the second user identification card resides in the target serving cell.

The SIM card may store relevant information of the cell after each time of residence of the cell, thereby generating a historical residence record of the SIM card, where the relevant information includes at least frequency band information of the cell.

In this example, it can be seen that, by searching the historical residence record of the SIM card stored in the electronic device for the cell meeting the conditions, the network searching process for the second subscriber identity card can be faster, so that the network searching efficiency is improved, and since the historical residence record can store information such as relevant identifiers of the cells, the subsequent residence process can be accelerated, and the network residence efficiency and success rate are improved.

In one possible embodiment, the camping on the target serving cell comprises: acquiring a cell identifier and a carrier frequency point number of the target service cell; and registering the cell according to the cell identification and the carrier frequency point number so as to reside in the target service cell.

The cell is used as the minimum service unit for UE access, and is composed of carriers and sectors, each sector uses one or more wireless carriers to complete wireless coverage, and each wireless carrier uses a certain carrier frequency point. The sector refers to a wireless coverage area covering a certain geographic area, the wireless coverage area is divided, and the carrier frequency point number is used for uniquely identifying the frequency range where a certain LTE system is located, and can be used for determining a specific cell as well as the cell identification. The registration and residence of the network cell can be realized by acquiring the cell identification and the carrier frequency point number of the target service cell.

After determining the target service cell, the electronic device acquires the cell identifier and carrier frequency point number (EARFCN 1300, PCI 196) of the target service cell, registers on the cell (EARFCN 1300, PCI 196) and resides in the target service cell, so that the electronic device can switch to DSDA mode, the first subscriber identity card can normally perform voice call, and the second subscriber identity card can also perform data service or voice service.

In this example, the cell identifier and the carrier frequency point number of the target serving cell are obtained, so that the electronic device can determine the specific target cell to realize cell registration and residence, thus ensuring that the electronic device can smoothly and rapidly perform cell registration and residence, and improving the stability and efficiency of residence cell flow.

In one possible embodiment, the determining a target serving cell for camping on from the at least one candidate serving cell includes: acquiring a current signal strength value and a paging cycle of the at least one candidate serving cell; respectively calculating the priority value of each candidate service cell according to the current signal strength value and the paging cycle; and taking the candidate serving cell with the largest priority value as the target serving cell.

Wherein, the larger the priority value is, the more suitable for the second user identification card to reside on the network, and the network service with better quality than other candidate service cells can be provided. The current signal strength value of the candidate serving cell is used for representing the signal strength of the cell at the current moment, and preferably, the cell with the largest current signal strength is selected, so that the electronic equipment is facilitated to receive signals, and the stability of processing services is improved. The problem of too long connection delay caused by too long paging interval may occur in the case of too long paging period, and the power consumption of the electronic device may be increased if too short paging period, so that the length of the paging period is not too long or too short.

Optionally, a priority value calculating function is preset in the electronic device, and an optimal paging cycle is preset, where the calculating function is proportional to the magnitude of the current signal strength value of the candidate serving cell, and is inversely proportional to the absolute value of the difference between the paging cycle of the candidate serving cell and the optimal paging cycle. The priority value of each candidate service cell is calculated through the priority value calculation function, so that the candidate service cell with the largest priority value is selected as a target service cell, and the service cell with the highest quality of network service can be selected for network residence operation.

It can be seen that, in this example, by acquiring the current signal strength value and the paging cycle of at least one candidate serving cell, and calculating the priority value of each candidate serving cell according to the current signal strength value and the paging cycle, the candidate serving cell with the largest priority value is taken as the target serving cell. Therefore, the attributes of the cells can be quantized into numerical values, the advantages and disadvantages of the candidate service cells are ordered according to the priority values through corresponding calculation functions, and the most suitable and best-quality cell in the candidate service cells can be selected as the object of second user identification card network residence through selecting the cell with the largest priority value, so that user experience, network residence efficiency and network service stability are improved.

In one possible embodiment, after said controlling said second subscriber identity card to camp on a target serving cell to support said dual card dual pass function, said method further comprises: acquiring a tracking area list pre-stored by the electronic equipment and a target tracking area where the target service cell is located; judging whether the tracking area list contains the target tracking area or not: if yes, the tracking area position updating flow is not required to be executed; if not, the tracking area location updating flow is initiated to the network equipment to update the location.

The tracking area list contains a plurality of tracking areas, the network device is MME (Mobility Management Entity), the MME is a key control node of the LTE access network and is responsible for positioning the UE in an idle mode, the paging process comprises a relay, and the MME is simply responsible for a signaling processing part.

Optionally, instead of initiating a TAU procedure after camping on a new cell, periodic tracking area location updates may be performed by timing the location of the tracking area within the electronic device to locate it in time, or when the electronic device returns from other systems (i.e., from other camping modes back to LTE camping modes, such as from GSM back to LTE). The network device can timely obtain the position of the electronic device and the tracking area where the electronic device is located through TAU updating, so that the electronic device can be normally paged and information can be obtained.

In the LTE network, in order to confirm the location of the communication device, an LTE network coverage Area is divided into a plurality of Tracking Areas (TAs), and a TA is defined as a free mobile Area where the UE does not need to update a location service. However, since the TA is a physical space configuration of the base station and is not suitable for frequent updating, a concept of a tracking area list (tarist) appears, that is, a group of TAs are combined into a list, the UE receives a tracking area list allocated by the network device, and the TA updating is not required when the UE moves in the tracking area list, so that frequent interaction with the network can be reduced. If the UE enters a new tracking area that is not in its registered tracking area list, an initiate TAU procedure needs to be performed to let the MME reassign the new tracking area list to the UE.

In this example, whether the tracking area position update process needs to be initiated to the network device to perform the position update is judged by acquiring the tracking area list pre-stored by the electronic device and the target tracking area where the target serving cell is located, so that the position recorded by the electronic device in the network side can be ensured to be updated in time, and the normal paging and information issuing by the network can be ensured.
