In the embodiments of the present disclosure, these operations or steps can be performed in series; these operations or steps can also be performed in parallel; or some of these operations or steps can be performed.

[0053] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only for illustrative purposes and are not used to limit the scope of these messages or information. It is understandable that before using the technical solutions disclosed in the embodiments of the present disclosure, the types, scope of use, usage scenarios, etc. of the personal information involved in the present disclosure should be informed to the user in an appropriate manner in accordance with relevant laws and regulations and the user's authorization should be obtained. The present disclosure is described below in conjunction with specific embodiments.

[0054] First, the application scenario of the present disclosure is described. In the current related technology, the general process of terminal network registration is as follows:

[0055] Step 1: After the UE is turned on, it will first use the RPLMN (Registered PLMN) to search for the network. PLMN (Public Land Mobile Network) refers to the public land mobile network.

[0056] Step 2: Unable to find the network corresponding to RPLMN, and full band scan failed.

[0057] Step 3: In NSA network, EHPLMN (Equivalent Home PLMN) is a local PLMN with the same status as the PLMN currently selected by the terminal. Or OPLMN (Operator Controlled PLMN). When the operator burns the card, the operator PLMN that has signed a roaming agreement with the operator will be written into the USIM card as OPLMN as a suggestion for the user to select a network later. Or UPLMN (User Controlled PLMN) is the PLMN selected by the terminal when the user manually selects the network, and the USIM card will store it. Or PPLMN (Prefer PLMN) is used to search the network.

[0058] Step 4: Find a suitable roaming network to register.

[0059] 5G (5th-Generation, fifth-generation mobile communication technology) SA (Standalone Architecture, independent networking) international roaming means that under the SA mode, users of the home network use 5G services in the roaming area by accessing the 5GSA network of the visited network. The applicant found that in the above-mentioned related technologies, it can be seen that since the roaming network has no historical frequency information, the terminal will perform a full band search, which will increase the network search time and thus reduce the user experience; on the other hand, the terminal will not give priority to 5G SA network registration judgment in the roaming PLMN selection, which may result in registration on a non-5G SA network, which will cause the user data service rate to decrease, thereby further reducing the user experience.

[0060] The disclosed embodiment obtains and updates the 5G SA network frequency information of the roaming location, preferentially scans the 5G SA network frequency, speeds up the network search speed (without full-band network search), and resides in the 5G SA network of the roaming location after a successful network search, thereby providing users with a better data usage experience and improving user satisfaction.

[0061] Figure 1 FIG. 1 is a flow chart of a communication method according to an exemplary embodiment. Figure 1 As shown, the present disclosure provides a communication method, which may include the following steps:

[0062] In step S10, it is determined that the terminal is in a roaming state and that the terminal supports 5G independent networking services.

[0063] In this step, it is determined that the terminal is in a roaming state and that the terminal supports 5G independent networking services. For example, after the terminal fails to register with the public land mobile network, a designated system information block message of the visited network can be obtained through a full-band search; then, according to the designated system information block message, it is determined that the visited network is a roaming network, thereby determining that the terminal is in a roaming state.

[0064] In step S20, according to the country code of the roaming network in which the terminal is located, network-related information of the roaming area to which the roaming network belongs that supports 5G independent networking is obtained, and the network-related information includes the network code and the frequency information of the network corresponding to the network code.

[0065] In this step, according to the country code of the roaming network where the terminal is located, the network-related information of the roaming area supporting 5G independent networking is obtained, and the network-related information includes the network code and the frequency information of the network corresponding to the network code. Exemplarily, according to the country code of the roaming network, the network-related information of the roaming area supporting 5G independent networking can be obtained through the cloud server.

[0066] In step S30, network search and network access are performed according to the network related information.

[0067] In this step, the network is searched and resident according to the network-related information. For example, the network search can be performed according to the frequency information in the network-related information, and the frequency of the 5G SA network is searched first to reduce the network search time, and the network is resident after the network search is successful to enjoy higher-speed data service.

[0068] In summary, the disclosed embodiment provides a communication method, the method comprising: determining that a terminal is in a roaming state and that the terminal supports 5G independent networking services; obtaining network-related information that supports 5G independent networking in the roaming area to which the roaming network belongs according to the country code of the roaming network where the terminal is located, the network-related information including the network code and the frequency information of the network corresponding to the network code; searching for and staying in the network according to the network-related information. The disclosed embodiment can solve the problem in the related art that when a terminal moves from a non-5G independent networking network where it resides to an area where a 5G independent networking network exists, it cannot quickly register with a 5G independent networking network. By preferentially scanning the preset 5G SA frequency information, the scanning time is reduced, the registration speed of the terminal roaming to the 5G independent networking network is increased, and the user experience and satisfaction are improved.

[0069] Figure 2 FIG. 1 is a flow chart of a communication method according to an exemplary embodiment. Figure 2 As shown, the step of determining that the terminal is in a roaming state may include the following steps:

[0070] In step S101, after the terminal fails to register with the public land mobile network, a designated system information block message of the visited network is obtained through a full-band search.

[0071] In this step, after the terminal fails to register with the public land mobile network, the designated system information block message of the visited network is obtained through a full-band search. Exemplarily, after the terminal fails to register with the public land mobile network (PLMN), the terminal can obtain the designated system information block (System Information Block) message of the visited network through a full-band search. For example, the designated system information block message can be a SIB1 message of the 5G network, which includes NAS (Network Attached Storage) information and timers and counters when the UE is in idle mode and connected mode.

[0072] In step S102, according to the designated system information block message, it is determined that the visited network is a roaming network and the terminal is in a roaming state.

[0073] In this step, according to the specified system information block message, it is determined that the visited network is a roaming network and the terminal is in a roaming state. Exemplarily, the terminal can determine that the visited network is a roaming network and the terminal is in a roaming state according to the country code and network code information in the specified system information block message.

[0074] Figure 3 FIG. 1 is a flow chart of a communication method according to an exemplary embodiment. Figure 3 As shown, the designated system information block message is a SIB1 message, and determining, according to the designated system information block message, that the visited network is a roaming network and the terminal is in a roaming state may include the following steps:

[0075] In step S1021, the first country code and the first network code in the SIB1 message are obtained.

[0076] In this step, the first country code and the first network code in the SIB1 message are obtained. Exemplarily, in 5GNR (New Radio), SIB1 usually carries information related to whether the UE is allowed to access the cell and defines the scheduling of other system information; in addition, it also provides radio resource configuration information shared by all UEs and prohibition information required for unified access control. The terminal can obtain the MCC and MNC codes of the visited network based on the NAS information in the SIB1 message. The MCC of the visited network is the first country code, and the MNC of the visited network is the first network code.

[0077] In step S1022, a second country code and a second network code in the SIM card of the terminal are obtained.

[0078] In this step, the second country code and the second network code in the SIM card of the terminal are obtained. Exemplarily, the terminal can read the MCC and MNC codes stored in the SIM card, that is, the second country code and the second network code.

[0079] In step S1023, when the first country code is different from the second country code and the first network code is different from the second network code, it is determined that the visited network is a roaming network and the terminal is in a roaming state.

[0080] In this step, when the first country code is different from the second country code, and the first network code is different from the second network code, it is determined that the visited network is a roaming network and the terminal is in a roaming state. Exemplarily, by comparing the first country code and the second country code, and comparing the first network code and the second network code, it is determined whether the visited network is a roaming network and whether the terminal is in a roaming state. If the first country code and the second country code are the same, and the first network code and the second network code are different, it can be determined that the terminal is in a domestic roaming state. If the first country code and the second country code are different, it can be determined that the terminal is in an international roaming state.

[0081] Figure 4 FIG. 1 is a flow chart of a communication method according to an exemplary embodiment. Figure 4 As shown, obtaining network-related information that supports 5G independent networking in the roaming area to which the roaming network belongs according to the country code of the roaming network in which the terminal is located may include the following steps:

[0082] In step S201, the network related information is obtained through a cloud server according to the country code of the roaming network.

[0083] In this step, the cloud server obtains network-related information of the roaming location according to the country code MCC of the roaming network. Exemplarily, the cloud server may store network configuration information of the roaming location, which may include information such as the number of networks, network types, network frequencies, network operators, and network charges.

[0084] Figure 5 FIG. 1 is a flow chart of a communication method according to an exemplary embodiment. Figure 5 As shown, obtaining the network related information through a cloud server according to the country code of the roaming network may include the following steps:

[0085] In step S2011, after the terminal is turned on, it is connected to the cloud server via a WIFI network.

[0086] In this step, after the terminal is turned on, it connects to the cloud server through the WIFI network to obtain network related information. For example, after the terminal is turned on, since it may not have registered on the local network, or in order to avoid high roaming data communication charges, it can choose to connect to the cloud server through the WIFI network to obtain network related information.

[0087] In step S2012, after the terminal is connected to the server, the network related information is obtained from the server according to the country code of the roaming network.

[0088] In this step, after the terminal is connected to the server, the roaming network related information corresponding to the country code MCC is obtained from the server according to the country code MCC of the roaming network.

[0089] Figure 6 FIG. 1 is a flow chart of a communication method according to an exemplary embodiment. Figure 6 As shown, the obtaining of the network related information through the cloud server according to the country code of the roaming network may also include the following steps:

[0090] In step S2013, the network related information is obtained from the server, and the network related information stored in the terminal is updated.

[0091] In this step, the network-related information of the roaming location is obtained from the server, and the network-related information stored in the terminal is updated. Exemplarily, the terminal can obtain the network-related information corresponding to the country code MCC of the roaming network through the cloud server, and then update the network-related information stored in the terminal. For example, the network-related information of the roaming location can be stored in the SIM card of the terminal. In this way, the network search speed can be accelerated when registering with the roaming location network next time.

[0092] Figure 7 FIG. 1 is a flow chart of a communication method according to an exemplary embodiment. Figure 7 As shown, updating the network related information stored in the terminal may include the following steps:

[0093] In step S20131, the terminal may also update the network related information stored in the modem of the terminal based on the network related information obtained from the server, so as to facilitate the rapid network registration in the roaming area in the future.

[0094] Figure 8 FIG. 1 is a flow chart of a communication method according to an exemplary embodiment. Figure 8As shown, searching the network and staying on the network according to the network related information may include the following steps:

[0095] In step S301, a network search is performed according to the frequency information in the network related information, and after the network search is successful, the searched target network is resident.

[0096] In this step, the network search is performed according to the frequency information in the network-related information, and the searched target network is resident after the network search is successful. Exemplarily, the terminal can preferentially scan and search for network frequencies that support 5GSA according to the frequency information in the network-related information, instead of adopting a blind full-band network search strategy, so as to speed up the network search speed and network search success rate, improve user experience, and reside in the 5G SA network after the network search is successful to enjoy higher-speed data service services, further improving user experience and satisfaction.

[0097] In summary, the disclosed embodiment provides a communication method, the method comprising: determining that a terminal is in a roaming state and that the terminal supports 5G independent networking services; obtaining network-related information that supports 5G independent networking in the roaming area to which the roaming network belongs according to the country code of the roaming network where the terminal is located, the network-related information including the network code and the frequency information of the network corresponding to the network code; searching for and staying in the network according to the network-related information. The disclosed embodiment can solve the problem in the related art that when a terminal moves from a non-5G independent networking network where it resides to an area where a 5G independent networking network exists, it cannot quickly register with a 5G independent networking network. By preferentially scanning the preset 5G SA frequency information, the scanning time is reduced, the registration speed of the terminal roaming to the 5G independent networking network is increased, and the user experience and satisfaction are improved.
