Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The main solution of the embodiment of the application is as follows: when the mobile terminal selects a cell, determining a first frequency band of a first network, wherein the first frequency band is a network frequency band of the first network supported by a target operator, and the target operator is an operator to which a user identity identification card currently used by the mobile terminal belongs; and attempting a cell camping process on the first frequency band.

If the mobile terminal does not find a suitable cell to camp on in the matched and supported 5G frequency band, the mobile terminal is switched to the 4G/3G/2G system to try a cell selection process so as to ensure that the mobile terminal can camp on the network quickly and can provide normal service. Therefore, the time consumed by the mobile terminal to stay in the proper cell can be effectively reduced, the performance of the mobile terminal can be improved, and better use experience is provided for the user.

SIM (subscriber Identity Module) card, a client identification module, also called as a smart card and a user Identity identification card, which stores the information of the digital mobile phone client, the encrypted key, the telephone book of the user and other contents, can be used for the identification of the GSM network client and encrypting the voice information when the client calls.
A usim (universal Subscriber Identity module) card and a global Subscriber Identity Module (SIM) card refer to a third generation mobile phone card, also called a global Subscriber Identity module (usim) card and an upgraded SIM card. The USIM card not only has an authentication function, but also can support a plurality of application platforms, for example, an electronic wallet, an electronic credit card, an electronic ticket, and the like can be implemented on a mobile phone. Besides supporting multiple applications, the USIM card upgrades the algorithm in terms of security and adds the authentication function of the card to the network.
NAS (Non-access stratum) exists in a radio communication protocol stack of UMTS (Universal Mobile Telecommunications System), and serves as a functional layer between a core network and a user equipment, and supports signaling and data transmission between the core network and the user equipment.
Cell selection: when the mobile phone is powered on or enters the coverage area from the blind area, the mobile phone searches all frequency points allowed by the PLMN and selects a proper cell to reside, and the process is called as cell selection.
After a cell has determined a PLMN, cell selection is performed in order to find a suitable cell residence in the PLMN. After selecting a PLMN, the NAS can control under which RAT cell selection is performed by indicating a Radio Access Technology (RAT) associated with the selected PLMN, maintaining a list of forbidden registration areas, and an equivalent PLMN list. A UE (User Equipment, User terminal) performs idle mode measurements and then selects a suitable cell according to a cell selection criterion.
The cell selection includes initial cell selection and stored information cell selection (StoreList cell selection), wherein:
initial cell selection, this process does not require that the RF (Radio Frequency) channel information of the E-UTRA (Evolved-UMTS Terrestrial Radio Access) carrier Frequency be known in advance. The UE searches RF channels within all E-UTRA bandwidths to find a suitable cell. On each carrier frequency, the physical layer first searches for the strongest cell and reads the System Information (SI) of the cell according to a cell search procedure, the UE evaluates whether the cell is a suitable cell according to S criteria, and the cell selection procedure is terminated once a suitable cell is found. If the cell is not a suitable cell, RRC (Radio Resource Control) requires the physical layer to search for the second strongest cell, and so on, until a suitable cell is found and camped.
In the process, the UE needs to store previously received measurement control information or a list of cells to be searched, including carrier frequency information or optional cell parameters. And the UE searches a first cell in the cell list, the physical layer reads the system information of the cell through the cell searching process and judges whether the cell is a proper cell according to the S criterion, if so, the terminal selects the cell, and the cell selecting process is finished. If the cell is not a suitable cell, the next cell in the cell list is searched, and so on. If none of the cells in the list are suitable cells, an initial cell selection procedure is initiated.
The cell search procedure is used to read cell system messages whether for initial cell selection or stored information cell selection procedures. The cell search process is a process in which the UE and the cell acquire time and frequency synchronization and detect a cell ID. The main difference between the E-UTRA cell search process and the UTRA system is that it should be able to support different system bandwidths (1.4-20 MHz). Cell search is implemented through several downlink channels including a Primary Synchronization Channel (PSCH), a Secondary Synchronization Channel (SSCH), a Broadcast Channel (BCH), and a downlink Reference Signal (RS).
In the embodiment of the present application, in the existing related scheme, in a network camping process in a mobile terminal 5G system, if there is no prior information of a StoreList (storage information) or a cell in the StoreList is not suitable for camping, the mobile terminal needs to perform a full-band network searching process. If the mobile terminal executes the full-band network searching process in the 5G system, the problem of too long network residence time of the mobile terminal is caused, which not only affects the user experience, but also affects the overall performance of the mobile terminal (e.g., power consumption of the mobile terminal).
In addition, the 5G frequency band deployed by a certain operator when deploying a 5G network in a certain country is limited, and not a certain operator supports all the 5G frequency bands in a certain country, that is, if the mobile terminal only tries to search for the 5G frequency band supported by the operator to which the (U) SIM card belongs, if no suitable cell is found in the supported 5G frequency band, the mobile terminal directly switches to the 2G/3G/4G network to try to camp, so that the network camping time of the mobile terminal is effectively shortened, the user experience is improved, and the overall performance of the mobile terminal is improved.
Therefore, the solution provided by the embodiment of the application can shorten the network residence time in the network residence process of the mobile terminal and improve the overall performance of the mobile terminal.

Based on the above terminal device architecture but not limited to the above architecture, embodiments of the method of the present application are provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating an exemplary embodiment of a web hosting method according to the present application. The network residing method comprises the following steps:
step S201, when a mobile terminal performs cell selection, determining a first frequency band of a first network, wherein the first frequency band is a network frequency band of the first network supported by a target operator, and the target operator is an operator to which a user identity identification card currently used by the mobile terminal belongs;
the execution main body of the method can be a network-residing device of the mobile terminal, and the network-residing device of the mobile terminal is used for controlling and managing the selected network-residing process of the mobile terminal cell. The network-residing device of the mobile terminal may be a device which is independent of the terminal equipment and can realize the cell selection flow processing control, and the device may be carried on the mobile terminal such as a mobile phone in the form of hardware or software. In addition, the execution main body of the method of the embodiment can also be directly a mobile terminal such as a mobile phone. This embodiment is exemplified by a mobile phone.
The mobile terminal is provided with a subscriber identity module card, which can be a SIM card or a USIM card.
Taking the cell selection camping process of the mobile terminal in the 5G network as an example, when the mobile terminal triggers power-on network selection or loses coverage and returns to the network (loses network in the cell camping process), the cell selection process is preferentially selected to be executed in the 5G network.
In the technical scheme of the embodiment, the mobile terminal under the 5G network can quickly reside in a proper cell when the mobile terminal is started to select the network or loses coverage and returns to the network.
Specifically, when a mobile terminal performs cell selection, a first frequency band of a first network is determined, where the first frequency band is a network frequency band of the first network supported by a target operator, and the target operator is an operator to which a subscriber identity module card (SIM card or USIM card) currently used by the mobile terminal belongs. Because it is considered that some mobile phones may be installed with two cards, for example, two SIM cards, in this scheme, the target operator supporting the first frequency band of the first network is an operator to which a subscriber identity module (SIM card or USIM card) currently used by the mobile terminal belongs, and the currently used SIM card or USIM card is an SIM card or USIM card currently used for searching, residing, and surfing.
When the mobile terminal performs cell selection, a first frequency band of a first network is determined, and a network frequency band of the first network can be supported by an operator to which a user identity identification card of the mobile terminal belongs by searching, wherein the first network can be a 5G network, and the network frequency band of the first network can be the 5G network frequency band.
As mentioned above, in the 5G system, two frequency ranges FR1(410 MHz-7125 MHz) and FR2(24250 MHz-52600 MHz) are defined, there are a total of forty working frequency bands, which is much more than the bandwidth and frequency band number of 2G/3G/4G, so it takes a long time to perform the synchronization of the full-band network search in the 5G system. In this embodiment, when the mobile terminal performs cell selection, only the 5G network frequency band supported by the operator to which the SIM card or USIM card of the mobile terminal belongs is searched.
The 5G network frequency bands supported by operators in various regions of various countries can be pre-configured for search and query.
For example, when configuring, the supported 5G band information supported by the corresponding operator in the corresponding country may be represented by support5 gBand. In a specific implementation, the support5 gbands may use bits of a 64-bit integer array to indicate whether a BAND (frequency BAND) is supported, for example, the configurations of bits _1_ 640 x0000010000000001 and bits _65_ 1280 x 00000000000000006000 indicate that BAND1, BAND41, BAND78 and BAND79 are supported.
Therefore, after the technical scheme is applied, the mobile terminal only tries to search and synchronize the 5G network frequency band supported by the operator to which the (U) SIM card belongs in the cell selection process such as power-on network selection or loss coverage network return and the like, and does not try to search and synchronize the full frequency band, so that the network residence time of the mobile terminal can be effectively shortened, the user experience is improved, and the overall performance of the mobile terminal is improved.
Step S202, a cell camping procedure is attempted on the first frequency band.
After the searched 5G network frequency band supported by the operator to which the user identity identification card of the mobile terminal belongs, a cell residence process is directly tried on the 5G network frequency band supported by the operator, so that the residence process of the 5G cell can be accelerated, frequency sweeping attempts are not performed on all forty or more frequency bands of a 5G system, the network residence time of the mobile terminal is effectively shortened, the user experience is improved, and the overall performance of the mobile terminal is improved.
Further, if the frequency band of the 5G network supported by the operator to which the user identification card of the mobile terminal belongs is not searched, a full-frequency-band search process may be performed to attempt cell camping.
In this embodiment, with the above scheme, when the mobile terminal performs cell selection, a first frequency band of a first network is determined, where the first frequency band is a network frequency band of the first network supported by a target operator, and the target operator is an operator to which a user identity card currently used by the mobile terminal belongs; and attempting a cell camping process on the first frequency band. By taking the 5G network as an example, after applying the technical scheme of the present application, the mobile terminal can directly try the cell residence process on the network frequency band supported by the operator in the cell selection processes such as power-on network selection or loss coverage back network, etc., so as to accelerate the residence process of the 5G cell, and do not perform frequency sweep attempts on all forty or more frequency bands of the 5G system. If the mobile terminal does not find a suitable cell to camp on in the matched and supported 5G frequency band, the mobile terminal is switched to the 4G/3G/2G system to try a cell selection process so as to ensure that the mobile terminal can camp on the network quickly and can provide normal service. Therefore, the time consumed by the mobile terminal to stay in the proper cell can be effectively reduced, the performance of the mobile terminal can be improved, and better use experience is provided for the user.
Further, as an implementation manner, taking the predetermined type of network frequency band as a 5G network frequency band as an example, the step S201: when the mobile terminal performs cell selection, determining the first frequency band of the first network may include:
in a 5G network, when the mobile terminal selects a cell, current network information is obtained;
and determining the 5G network frequency band supported by the target operator according to the current network information and a preset 5G network frequency band configuration table.
The method specifically comprises the following steps: step S2011, in a 5G network, when the mobile terminal performs cell selection, if the mobile terminal does not reside in a cell meeting a condition in a StoreList process of the cell selection, obtaining the current network information through a StoreList network searching process, and if the current network information is obtained through the StoreList network searching process, determining a 5G network frequency band supported by a target operator, that is, a 5G network frequency band supported by an operator to which a subscriber identity card of the mobile terminal belongs, according to the current network information and in combination with a preset 5G network frequency band configuration table.
The step S202 may include:
step S2020, a cell camping procedure is attempted on the determined 5G network frequency band.
The storeist process is a cell selection process for storing information, and in the process, the mobile terminal needs to store previously received measurement control information or a cell list which needs to be searched, including carrier frequency information or optional cell parameters and the like. The mobile terminal searches a first cell in the cell list, the physical layer reads the system information of the cell through the cell searching process and judges whether the cell is a proper cell according to the S criterion, if so, the mobile terminal selects the cell, and the cell selecting process is completed. If the cell is not a suitable cell, the next cell in the cell list is searched, and so on. If none of the cells in the list are suitable cells, an initial cell selection procedure is initiated.
In this embodiment, when the mobile terminal triggers power-on network selection or loses coverage and returns to the network (loses network during cell camping), the mobile terminal preferentially selects to execute the cell selection process in the 5G network.
In the cell selection process, the mobile terminal preferentially attempts to camp on the cell in the StoreList, wherein, whether valid 5G network StoreList cell information exists or not is firstly checked, namely prior information is related to the serving cell where the mobile terminal currently resides in the network and the adjacent cells, if the valid StoreList cell information exists, the StoreList network searching process is executed to camp on a proper cell, and the mobile terminal preferentially performs measurement synchronization on the cells, acquires system information and stores PLMN information (mainly MCC) of the current network, namely current network information.
If the mobile terminal resides in a suitable 5G cell in the StoreList network searching process, the cell selection process is ended; otherwise, it indicates that there is no suitable cell to camp on in StoreList. If the mobile terminal does not reside in a cell meeting the conditions in a StoreList process selected by the cell and the current network information is obtained through a StoreList network searching process, searching a 5G network frequency band supported by an operator to which a subscriber identity module card (SIM card or USIM card) of the mobile terminal belongs according to the current network information and by combining a preset 5G network frequency band configuration table.
The 5G network frequency band configuration table is arranged on the mobile terminal and maintained by the mobile terminal, the 5G network frequency band configuration table comprises 5G network frequency bands supported by operators in various regions of various countries, and information in the 5G network frequency band configuration table can be collected in advance and preset in the mobile terminal. When the mobile terminal executes a full-band cell selection process under a 5G system, a 5G frequency band configuration table is firstly inquired according to the current network environment where the mobile terminal is located so as to obtain a 5G network frequency band supported by an operator, then network searching trying residence is carried out aiming at the matched 5G frequency band, and a 5G network frequency band which is not supported by the operator is not tried in the cell selection process, so that the network residence time of the mobile terminal can be effectively shortened.
The format of a 5G network frequency band configuration table maintained by the mobile terminal is as follows:
table 1: 5G network frequency band configuration table
Wherein, the sequence number is the sequence number when adding into the table;
MCC is a mobile country number in PLMN and can uniquely represent the country of the mobile subscriber;
the MNC is a mobile network number in the PLMN and can uniquely represent a network in the country, namely operator information;
and the support5gBand is the 5G frequency band information supported by the corresponding operator of the corresponding country.
In a specific implementation, the support5 gbands may use bits of a 64-bit integer array to indicate whether a BAND supports, for example, the configuration of bits _1_ 640 x0000010000000001 and bits _65_ 1280 x 00000000000000006000 indicates that BAND1, BAND41, BAND78 and BAND79 are supported.
As another embodiment, the following scheme may be adopted for searching the 5G network frequency band supported by the operator to which the user identification card of the mobile terminal belongs according to the current network information and by combining a preset 5G network frequency band configuration table:
and searching the 5G network frequency band supported by the operator to which the user identity identification card of the mobile terminal belongs according to the current network information and by combining a preset 5G network frequency band configuration table and the user identity identification card information of the mobile terminal.
In this embodiment, through the above-mentioned scheme, if the mobile terminal does not reside in a suitable cell in the StoreList (cell selection) process, and the current network information is obtained through the StoreList network searching process (that is, the country and region where the current mobile terminal is located can be known through the PLMN of the current network), the 5G network frequency band currently supported by the operator to which the mobile terminal belongs can be obtained by combining the 5G network frequency band configuration table and the (U) SIM card information, and the network searching synchronization attempt network residence process is performed only on the supported 5G network frequency band, instead of performing the frequency sweep attempt on all forty or more frequency bands of the 5G system. Therefore, the time consumed by the mobile terminal to stay in the proper cell can be effectively reduced, the performance of the mobile terminal can be improved, and better use experience is provided for the user.

Because the 4G/3G/2G system is in the global ubiquitous department network, the frequency band and the frequency point are fewer, the PLMN information is in SI3/SI4 and the network broadcasting is frequent, the time consumed for acquiring only the PLMN information of the current network in the 4G/3G/2G system is very short. And after the PLMN information of the current network is acquired, terminating the subsequent flow of the 4G/3G/2G system, and quickly returning to the 5G system to continue to execute the frequency band network searching flow.
And after the mobile terminal is switched back to the 5G network, searching the 5G network frequency band supported by the operator to which the user identity identification card of the mobile terminal belongs according to the current network information and by combining a preset 5G network frequency band configuration table.

Compared with the embodiment shown in fig. 3, this embodiment further includes a specific implementation scheme that, when the mobile terminal performs cell selection, the mobile terminal searches a network frequency band of a predetermined type supported by an operator to which the user identity card of the mobile terminal belongs, so as to determine the first frequency band of the first network.
Specifically, when the mobile terminal triggers power-on network selection or loses coverage and returns to the network, the cell selection process is preferentially selected to be executed in the 5G network.
In the cell selection process, the mobile terminal preferentially attempts to camp on the cell in the StoreList, wherein whether valid 5G network StoreList cell information exists or not is checked, that is, prior information is related to the serving cell where the mobile terminal last resided in the camping network and the neighboring cells thereof.
If the cell information of the 5G network StoreList does not exist, judging that the mobile terminal does not pass through the StoreList process; if the valid StoreList cell information exists, executing a StoreList network searching process to reside in a proper cell, and the mobile terminal preferentially performs measurement synchronization on the cells, acquires system information and stores the PLMN information (mainly MCC) of the current network, namely the current network information.
If the mobile terminal resides in a suitable 5G cell in the StoreList network searching process, the cell selection process is ended; otherwise, it indicates that there is no suitable cell to camp on in StoreList. If the mobile terminal does not reside in a cell meeting the conditions in a StoreList process selected by the cell and the current network information is obtained through a StoreList network searching process, searching a 5G network frequency band supported by an operator to which a subscriber identity module card (SIM card or USIM card) of the mobile terminal belongs according to the current network information and by combining a preset 5G network frequency band configuration table.
In this embodiment, with the above scheme, when the mobile terminal performs cell selection, a first frequency band of a first network is determined, where the first frequency band is a network frequency band of the first network supported by a target operator, and the target operator is an operator to which a user identity card currently used by the mobile terminal belongs; and attempting a cell camping process on the first frequency band. By taking the 5G network as an example, after the technical scheme of the application is applied, the cell residence process can be directly tried on the network frequency band supported by an operator in the cell selection process of starting up network selection or losing coverage and returning network and the like of the mobile terminal, the residence process of the 5G cell is accelerated, and the frequency sweep attempt is not performed on all frequency bands of the 5G system, so that the mobile terminal can rapidly reside in the network, the time consumed by the mobile terminal to reside in a proper cell is effectively reduced, the performance of the mobile terminal can be improved, and better use experience is provided for users.
The following describes the cell selection procedure under the 5G system in this embodiment in detail with reference to fig. 6:
in the technical scheme, the mobile terminal under the 5G system can quickly reside in a proper cell in the process of starting up network selection or losing coverage and returning to the network; the process is as follows:
1. when the mobile terminal triggers startup network selection or loses coverage and returns to the network, in step S100, the mobile terminal preferentially executes a cell selection process under a 5G system, and then executes step S101 to check whether StoreList cell information exists;
2. in step S101, in the network camping process of the mobile terminal, the cell that is camped in the StoreList is tried preferentially, and if the cell in the StoreList is not suitable for camping, the frequency sweeping process of the partial frequency band in the present technical solution is adopted. Therefore, in this step, it is checked whether there is valid storeist cell information of the 5G network, and if there is valid storeist cell information, step S102 is executed next to try to camp on the cell in the storeist; otherwise, executing step S105, and obtaining the PLMN information of the current network under 2G;
3. in step S102, a StoreList network searching procedure is executed, where the cell information in the StoreList is the serving cell where the mobile terminal is currently camped on the network last time and the information related to the neighboring cells, and the mobile terminal preferentially performs measurement synchronization on these cells, acquires system information, and stores PLMN (mainly MCC) information of the current network. Next, step S103 is executed to further check whether a suitable cell is camped in the StoreLis network searching process;
4. in step S103, if the mobile terminal resides in a suitable 5G cell in the StoreList network searching process, then step S108 is executed, and the process is ended; otherwise, it indicates that there is no suitable cell for residing in the StoreList, then step S104 is executed, and it is further checked whether PLMN information of the current network is obtained in the StoreList network searching process;
5. in step S104, it is checked whether the mobile terminal has obtained PLMN information of the current network in the StoreList network searching process (the country and region where the current mobile terminal is located can be known through MCC in the PLMN of the current network), if the mobile terminal has obtained PLMN information of the current network, then step S106 is executed, and supported 5G network frequency band information is obtained in combination with the PLMN of the current network, HPLMN in USIM (E), and 5G frequency band configuration table; otherwise, executing step S105, and obtaining the PLMN information of the current network under the 2G system;
6. in step S105, it indicates that the mobile terminal performs the network selection process under the 5G system to check that there is no StoreList prior information, or that there is no suitable network to camp on in the StoreList process and no PLMN information of the current network is acquired, at this time, the mobile terminal may quickly acquire the current network information under the 2G system. Because the 2G system has a small number of frequency bands and frequency points in the global ubiquitous network, the PLMN information is in SI3/SI4, and the network broadcasts frequently, the time consumed for acquiring only the PLMN information of the current network in the 2G system is very short. The process of rapidly acquiring the PLMN of the current network in the 2G system is not described in detail herein, and the process may be a network selection resident process in the 2G system, and only after acquiring the PLMN information of the current network, the subsequent process of the 2G system is terminated, and the 5G system is rapidly returned to continue to execute the frequency band network searching process. Next, step S106 is executed, and the supported 5G frequency band information is acquired by combining the PLMN of the current network, the HPLMN in USIM (E), and the 5G frequency band configuration table;
7. in step S106, it indicates that the mobile terminal is to execute a frequency band search procedure to camp on a suitable cell in the 5G system, so that the plmn (MCC), the HPLMN (MCC & MNC) in the USIM, and the MCC & MNC in the 5G network frequency band configuration table of the current network can be combined to obtain the 5G network frequency band information supported by the corresponding operator in the corresponding region from the 5G network frequency band configuration table, and then step S107 is executed to perform a cell selection procedure for the 5G network frequency band supported by the operator;
8. in step S107, the mobile terminal only needs to perform searching, synchronizing, and trying to camp in a suitable cell on the 5G network frequency band supported by the specific operator, and does not perform full-band search synchronization on all 5G frequency bands, so that the network camping duration of the mobile terminal can be effectively reduced, and the user experience is improved. If no valid 5G network frequency band information is acquired in step S106, only the full frequency band search process can be performed in this process to attempt cell camping. The specific cell selection process is not described in detail herein, and step S108 is executed next;
9. in step S108, if the mobile terminal has resided in a suitable cell, the process is ended; if the mobile terminal does not reside in a suitable cell in the matched and supported 5G frequency band, the mobile terminal switches to the 4G/3G/2G system to try a cell selection process to ensure that the mobile terminal can rapidly reside in the network and can provide normal service, and a network selection process under the 4G/3G/2G system is not described in detail herein.
Compared with the prior art, in the technical scheme, if the mobile terminal does not reside in a proper cell in the StoreList process and the current network information is obtained through the StoreList network searching process (namely the country and the region where the current mobile terminal is located can be known through the PLMN of the current network), the 5G network frequency band supported by the operator to which the mobile terminal belongs can be obtained by combining the 5G network frequency band configuration table and the (U) SIM card information, and the network searching synchronous network trying network residing process is only performed on the supported network frequency band; if no StoreList process exists or no current network information is acquired in the StoreList network searching process, the mobile terminal quickly acquires the current network information under 2G, and quickly returns to 5G after acquiring the current network PLMN under 2G to try to search the synchronously matched 5G network frequency band. If the mobile terminal does not find a suitable resident cell in the 5G network frequency band matched and supported by the mobile terminal, switching to a 4G/3G/2G system, and trying a cell selection process to ensure that the mobile terminal can be quickly resident in the network and can provide normal service.
The technical solution is explained in detail by the following specific examples:
take the example that the USIM card moving in China is started and parked in the China network:
the information of the 5G network frequency band configuration table maintained by the mobile terminal is assumed to be as shown in the following table:
table 2: 5G network frequency band configuration table (example)
Assuming that no StoreList prior information is detected after the mobile terminal is powered on, the current network environment, that is, PLMN information, is quickly acquired in the 2G system, for example, a china unicom signal in the current 2G network environment is strongest, and the acquired PLMN information is 46001.
Since the mobile terminal uses the USIM card of china mobile, 46000, 46002 and 46007 exist for (E) HPLMN in the card.
According to the prior art scheme, the mobile terminal does not have StoreList prior information under a 5G system, so that a full-BAND search process is performed, that is, from the sequence of N1, N2, N3 and N5 … N41 … N79, the mobile terminal sequentially tries until a suitable cell is found in N41 or N79, and if no suitable cell is found on N41 and N79, the mobile terminal still wants to try other BAND residences (since none of the BANDs are supported by the chinese movement, no suitable cell is found), so that the mobile terminal in the process necessarily consumes a long time to try to camp on the BAND of the suitable cell at all, and the overall performance of the mobile terminal is necessarily affected.
If the method according to the present technical solution is adopted, the mobile terminal obtains PLMN information of the current network in the 2G system first according to the cell selection procedure in the 5G system shown in fig. 6, because there is no storeist prior information, and then obtains the frequency band information of the 5G network as N41 and N79 by combining with (E) HPLMN in the USIM card and information in the 5G network frequency band configuration table. Therefore, the mobile terminal only tries the 5G cell residence process on the two frequency bands of N41 and N79, no more tries other thirty-few frequency bands, and if the N41 and N79 do not find a suitable cell, the mobile terminal directly tries the cell selection process under the 4G/3G/2G system, so as to ensure that the mobile terminal can rapidly camp on the network and can provide normal service.
Therefore, the technical scheme can enable the mobile terminal to directly try the cell residence process on the frequency BAND supported by an operator in the cell selection processes such as startup network selection, loss coverage network return and the like as much as possible, and does not perform frequency sweeping attempts on all forty or more BANDs of the 5G system, so that the time consumed by the mobile terminal to reside in a proper cell can be effectively reduced, the overall performance of the mobile terminal can be improved, and better use experience can be provided for users.
Further, as an extension of the present technical solution, in other embodiments, if it is detected that the USIM card identifier can be checked in a test card laboratory environment, and if the USIM card identifier is detected in an instrument test (a test performed in a laboratory network), the procedure in the present technical solution is not executed. In addition, in the roaming scene that the mobile terminal exits the HPLMN area, the RPLMN stored in the USIM card can be used to replace (E) the HPLMN to perform the process in the technical scheme again to obtain the supported 5G network frequency band information, so that the mobile terminal can be quickly resided in a proper cell.
In this embodiment, with the above scheme, when the mobile terminal performs cell selection, a first frequency band of a first network is determined, where the first frequency band is a network frequency band of the first network supported by a target operator, and the target operator is an operator to which a user identity card currently used by the mobile terminal belongs; and attempting a cell camping process on the first frequency band. By taking the 5G network as an example, after applying the technical scheme of the present application, the mobile terminal can directly try the cell residence process on the network frequency band supported by the operator in the cell selection processes such as power-on network selection or loss coverage back network, etc., so as to accelerate the residence process of the 5G cell, and do not perform frequency sweep attempts on all forty or more frequency bands of the 5G system. If the mobile terminal does not find a suitable cell to camp on in the matched and supported 5G frequency band, the mobile terminal is switched to the 4G/3G/2G system to try a cell selection process so as to ensure that the mobile terminal can camp on the network quickly and can provide normal service. Therefore, the time consumed by the mobile terminal to stay in the proper cell can be effectively reduced, the performance of the mobile terminal can be improved, and better use experience is provided for the user.
In addition, an embodiment of the present application further provides a network residence device, where the network residence device includes:
a search module, configured to determine a first frequency band of a first network when the mobile terminal performs cell selection, where the first frequency band is a network frequency band of the first network supported by a target operator, and the target operator is an operator to which a user identity card currently used by the mobile terminal belongs;
and the residing module is used for trying a cell residing process on the first frequency band.

By taking the 5G network as an example, after applying the technical scheme of the present application, the mobile terminal can directly try the cell residence process on the network frequency band supported by the operator in the cell selection processes such as power-on network selection or loss coverage back network, etc., so as to accelerate the residence process of the 5G cell, and do not perform frequency sweep attempts on all forty or more frequency bands of the 5G system. If the mobile terminal does not find a suitable cell to camp on in the matched and supported 5G frequency band, the mobile terminal is switched to the 4G/3G/2G system to try a cell selection process so as to ensure that the mobile terminal can camp on the network quickly and can provide normal service.
