The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

The embodiment of the present application provides a network search method. FIG. 1 is a flowchart of a network search method in an embodiment of the present application. As shown in FIG. 1, the method includes the following steps:

S101. Search the network in the full frequency band to determine the target MCC.

When the terminal enters other roaming countries, it needs to search and access the network at the roaming destination before it can communicate. An embodiment of the application provides a network search method, which provides a network search implementation method when a terminal enters a roaming country.

In the embodiment of this application, when the terminal arrives in some roaming countries or roaming destinations, it will first search the network from the historical MCC and PLMN. If the terminal can search for the network in the historical MCC and PLMN, it will use the searched network Determine the target MCC.

In the embodiment of the present application, when the system message of the network is not searched within a preset time, the network is searched in the entire frequency band, and the target MCC is searched.

Here, a preset time can be set in advance. If the terminal does not search for system messages about any network within the preset time, the terminal cannot confirm the current roaming destination. At this time, the terminal stops the current history. MCC and PLMN search the network, but start to search the network in the whole frequency band, and regard the first searched MCC as the target MCC. Conversely, if the terminal finds the system message of the network within the preset time, it decodes the system message of the network to obtain the target MCC, and then confirms the current roaming destination through the target MCC.

Among them, the preset time can be 1 minute. The preset time may be set based on actual network search conditions, which is not limited in the embodiment of the present application.

MCC is the mobile country code (Mobile Country Code, MCC). Illustratively, the country where each user currently enters can be distinguished through MCC. Among them, the resources of MCC are uniformly allocated by the International Telecommunication Union (ITU) And management, which uniquely identifies the country to which the mobile user belongs, with a total of 3 digits, for example, 460 for China and 525 for Singapore.

It should be noted that the terminal may be a mobile electronic device with a communication function, such as a smart phone or a tablet computer, which is not limited in the embodiment of the present application.

In the embodiment of this application, the terminal searches the network in the full frequency band, and in the process of searching for the target MCC, there is no need to specify the MCC or PLMN to search, as long as the system message can be searched in the shortest time, and the uniquely determined system message can be obtained from the system message. The MCC serves as the target MCC, so that the roaming destination (ie, the roaming country) is determined based on the target MCC.

It is understandable that if the terminal does not search the network successfully within the preset time, it will switch to the network search in the full frequency band. The useless search process is stopped in time, and the fastest MCC searched in the whole frequency band is the target MCC. The scope of the network is expanded, the success rate and speed of searching the network can be improved, and the fastest searched MCC is used as the target MCC, which effectively saves the time of searching the network.

Exemplarily, as shown in FIG. 2, a schematic diagram of a terminal searching for a target MCC in a full frequency band is shown. The terminal may include a non-access layer network search module and an access layer network search module. The non-access layer network search module stores historical MCCs previously searched or accessed by the terminal, and the terminal first searches the network through the non-access layer The module searches for historical MCC, and when the historical MCC is not searched for the preset time, it turns to inform the lower layer to search the network in the full frequency band, that is, the network search module of the access layer searches in the whole frequency band to quickly search for the MCC, that is, a new one is found MCC (target MCC), and the full frequency search network speeds up the update of the MCC. After the search and decoding of the target MCC is completed, the full frequency search network process can be stopped.

In some embodiments of the present application, since the roaming country where the terminal is located needs to be determined by the target MCC, the terminal searches the network in the full frequency band, and in the process of searching for the target MCC, the first searched PLMN can be decoded. Obtain the target MCC; the full-band scanning process is more hopping and flexible, and the terminal does not need to scan the full-band one by one, nor does it need to perform refined scanning, but preferentially search for system messages decoded by the cell in all supported frequency bands That is to say, when the terminal searches the network in the full frequency band, if it finds a system message, it can directly determine the target MCC through the system message, and then determine the roaming destination of the terminal. This process can speed up the acquisition of the target MCC.

In some embodiments of the present application, based on the target MCC, the terminal acquires the roaming target location information of the target object before acquiring the contracted network information corresponding to the target communication card; the terminal determines the target MCC based on the target location information.

Wherein, the target location information may be a description of longitude and latitude coordinate information, or a description of a country or region determined by the longitude and latitude coordinate information.

In some embodiments of the present application, the terminal can obtain the roaming target location information of the target object in the following manner: the terminal can perform satellite positioning through dedicated location information, such as GPS and Beidou positioning system to obtain the target location information corresponding to the terminal; The target location information corresponding to the terminal can be obtained through its own electronic itinerary, network order, and information records when passing through the customs location.

Exemplarily, the method for the terminal to determine the target MCC based on the target location information includes: after the terminal determines the target location information in the above manner, the terminal directly determines the roaming country according to the roaming target location information, and then determines the MCC corresponding to the roaming country (that is, the target MCC).

In some embodiments of the present application, the method for the terminal to determine the target MCC based on the target location information further includes: the terminal can preferentially search for the network information registered last time, if the registered network information is the network of the country where the terminal is currently roaming Information, the MCC corresponding to the roaming country can be determined directly through the network information, which can significantly shorten the time for the terminal to determine the target MCC.

S102. Obtain contracted network information corresponding to the target communication card based on the target MCC; the contracted network information includes contract information corresponding to the target MCC.

In the embodiment of the present application, the terminal determines the country information of the terminal roaming destination according to the target MCC, and then obtains the contracted network information of the target communication card in the country, so that the contracted information corresponding to the target MCC can be found through the contracted network information. Among them, the contract information includes contract data of countries that have contracted for international roaming.

Exemplarily, the target communication card is the communication card on the terminal, which is the medium through which the target object uses the terminal to communicate; among them, a target communication card can uniquely identify a target object, and the same target communication card can be used on different terminals A terminal can contain at least one target communication card, and only after the terminal is inserted into the target communication card, the target object can use the terminal to search the network.

In some embodiments of the application, by reading the operator information corresponding to the target communication card and the supported network standard, it can be determined whether the current terminal is in an international roaming state. If so, the terminal determines the terminal roaming country information according to the target MCC. According to the current roaming country, obtain the contracted network information corresponding to the target communication card.

Exemplarily, the target communication card may be a SIM card (Subscriber Identity Modula, SIM) supported by the Global System for Mobile Communications (GSM) or a UIM card (User Identity) supported by the CDMA system (Code Division Multiple Access, CDMA). Modula, UIM), and other identification cards for mobile communication, which are not limited in the embodiment of this application.

In the embodiments of this application, the contracted network information database refers to the network information database in the international roaming contract database, which can be: a network information form maintained by each operator for a communication network that has completed roaming agreement contracts in other countries Database, where each type of target communication card corresponds to the same type of contracted network information.

It is understandable that the contracted network information database includes contracted contracted network information corresponding to multiple operators, and the terminal needs to find the contracted network information consistent with the operator of the target communication card. For example, when the operator corresponding to the target communication card of the terminal is China Mobile, the contracted network information at this time includes the roaming network information of multiple countries contracted with China Mobile, that is, the terminal obtains the operation of the roaming country and issuance of the target communication card The contracted network information of the supplier is then automatically searched according to the network standard priority supported by the target communication card and the contracted network information of the target communication card in the country to achieve the purpose of searching the network.

In the embodiment of the present application, the contracted network information corresponding to the target communication card includes at least two of the following: at least one PLMN, the standard corresponding to each PLMN, the frequency information corresponding to each PLMN, and Corresponding frequency band information.

In the embodiment of this application, each PLMN in the contracted network information corresponds to different standard information, frequency band information, and frequency point information, which is not limited by the embodiment of this application.

In an exemplary application scenario, after determining the roaming destination of the terminal, the terminal obtains the contracted network information corresponding to the target communication card, and searches for the PLMN list in the contracted network information, where PLMN is a sorted list of at least one PLMN, and the terminal The system information can be searched for the PLMN with the highest network coverage in the PLMN list. Here, the network coverage is the description of the geographic location covered by the network. The search for the system information is in the order of priority from high to low. of. Standard information includes, but is not limited to, the fifth-generation mobile communication technology (5th-Generation, 5G), the fourth-generation mobile communication technology (4th-Generation, 4G), the third-generation mobile communication technology (3rd-Generation, 3G), and the second Generation mobile communication technology (2nd-Generation, 2G) and other network standards. Among them, the priority of the standard information from high to low is: 5G, 4G, 3G, 2G, the higher the priority of the standard information, the better the corresponding network information; if there is a sixth-generation mobile communication technology (6th-Generation, 6G) standard information, the priority corresponding to 6G is the highest, and so on, the embodiment of this application does not limit it.

In some embodiments of the present application, the terminal first searches for the standard information corresponding to the PLMN with the highest priority, and after finding the standard information, starts to scan the frequency point information and frequency band information under the PLMN.

Exemplarily, the contracted network information includes a PLMN list, where the order of the PLMN list is arranged according to the size of the network coverage, that is, the larger the network coverage, the higher the ranking.

In the embodiment of this application, the PLMN is composed of MCC and mobile network code MNC (Mobile Network Code, MNC). Once the MCC is set, it is not allowed to be changed. The MNC is generally assigned uniformly by the relevant telecommunications management department returning home. An operator can have one or more MNCs, but different operators cannot share the same MNC. Therefore, if there are multiple mobile network operators in the same country, they can be distinguished by MNC.

In some embodiments of the present application, based on the target MCC, the terminal obtains the contracted network information corresponding to the target communication card can be achieved by: statistic the historical network information of the target object; the terminal determines the network information related to the target object based on the historical network information. The target pass card and the contracted network information corresponding to the target MCC.

Exemplarily, when the target MCC has been determined, the current roaming destination of the terminal is known. If the historical network information that the terminal has registered before is counted, the target communication card corresponding to the roaming destination can be obtained. The contracted network information, when the terminal searches the network at the roaming destination, it directly searches for the corresponding contracted network information from the registered historical network information, and searches the network through the contracted network information.

It should be noted that, since the contracted network information obtained by the terminal through the above method is historical network information registered by the terminal, the terminal does not need to search one by one from the contracted network information database that includes multiple operators that is consistent with the operator of the target communication card. Sign up for network information, so you can quickly search the network.

In some embodiments of the present application, based on the target MCC, the terminal obtains the contracted network information corresponding to the target communication card can also be achieved by: the terminal receives the contracted network information database corresponding to different MCCs pushed by the network platform; from the contracted network information database , Determine the contracted network information corresponding to the target MCC and the target communication card.

Exemplarily, the receiving network platform can periodically push the contracted network information database corresponding to different MCCs to the terminal according to the user's needs. When the user performs a roaming search, it searches the contracted network information database for the contracted network information corresponding to the current roaming destination.

Exemplarily, as shown in Figure 3, to obtain a schematic diagram of contracted network information, the corresponding contracted network information can be pushed to the user terminal regularly or according to user needs through the network platform, or the user terminal can determine the corresponding contracted network information based on historical use of network information. The contracted network information, when the contracted network information is obtained, the corresponding PLMN, standard, frequency, and frequency band information are determined through the contracted network information.

Here, the network platform may be an operator or another information sending platform, which is not limited in the embodiment of the present application.

In the embodiment of this application, the contracted network information corresponding to the target communication card is obtained based on the target MCC; once the contracted network information corresponding to the target communication card is determined, only the PLMN list included in the contracted network information is searched, which can avoid all communications The PLMN under the network information of the network performs a traversal search, which can speed up the search speed of the PLMN.

S103: Determine the target PLMN based on the contracted network information.

S104: Perform network access according to the target PLMN.

In the embodiment of the present application, after obtaining the corresponding contracted network information, the terminal searches for the target PLMN from the PLMN list included in the contracted network information, and performs network access.

Exemplarily, after the terminal determines the MCC of the roaming destination, it searches for the PLMN in the contracted network information. When the target PLMN is found, it searches for the corresponding standard information according to the target PLMN, and then obtains the frequency point information corresponding to the standard information ; If the corresponding frequency point information is not obtained, obtain the frequency band information corresponding to the standard information.

In some embodiments of this application, when the terminal obtains the frequency band information and frequency point information corresponding to the standard information, if the frequency point information with a certain energy is found during the scanning process, it means that the frequency point is probably the terminal that can realize the network. For the accessed frequency point, the frequency point information is decoded to obtain the network information under the frequency point information, and the terminal performs registration and network access on the network information.

Exemplarily, as shown in FIG. 4, a schematic diagram of a terminal searching the network based on the contracted network information. The terminal may include a non-access layer network search module and an access layer network search module. After the non-access layer network search module determines a new MCC, that is, the target MCC, the non-access layer network search module requests the lower layer according to the contracted network information Perform network search, that is, the access layer network search module searches for the target PLMN, and then returns the search result of the target PLMN to the non-access layer network search module. The non-access layer network search module performs network access based on the returned target PLMN. Enter, you can complete the terminal search process.

The network search method provided by the embodiment of the present application searches the network in the full frequency band to determine the target MCC; based on the target MCC, obtains the contracted network information corresponding to the target communication card; the contracted network information includes the contract information corresponding to the target MCC; Based on the contracted network information, the target PLMN is determined, and network access is performed according to the target PLMN. Using the technical implementation scheme of the embodiments of the present application, on the one hand, in the process of determining the target MCC, no MCC or PLMN is specified, but the first searched PLMN is decoded by searching the network in the full frequency band to obtain the target MCC Because the entire search process does not need to be traversed one by one to search, as long as the system message of the network is found, the target MCC is determined through the system message, and then the roaming destination of the terminal is determined. This process can speed up the acquisition of the target MCC; On the one hand, by acquiring the contracted network information corresponding to the target communication card and searching only the PLMN included in the contracted network information, it is possible to avoid traversal search of PLMNs under all network information, thereby speeding up the PLMN search. It can be seen that the network search method of the embodiment of the present application determines the roaming destination of the terminal by speeding up the search of the target MCC, and at the same time, speeds up the search speed of the PLMN through the contracted network information, thereby saving the time for searching the network when the terminal is roaming, and improving the efficiency of the network search. .

In some embodiments of the present application, as shown in FIG. 5, which is a schematic diagram of a process for acquiring a target PLMN, when at least one PLMN includes multiple PLMNs arranged in sequence, the implementation of S103 includes: S1031-S1034, as follows:

S1031. Perform network search based on the i-th PLMN in at least one PLMN to obtain the i-th signal; where i is a positive integer greater than or equal to 1 and less than N, and N is the total number of at least one PLMN.

In this embodiment of the application, the subscription network information includes a PLMN list, and the PLMN list includes at least one PLMN, that is, N PLMNs, where the sequence of the multiple PLMNs included in the PLMN list is determined, and the multiple PLMNs It is arranged according to the size of the network coverage area, and is sequential, that is, among all the PLMNs included in the PLMN list, which PLMN has the larger the network coverage area, the higher the ranking.

In the embodiment of this application, the terminal searches for the PLMN in the order of arrangement, that is, the network coverage from high to low, that is, the terminal searches for the i-th PLMN, where the value of i starts from 1, when When i=1, it indicates that the network coverage of the PLMN is the largest, and the PLMN is searched first to obtain the i-th signal. The signal here refers to the signal on the frequency under the standard supported by the PLMN. Among them, i is a positive integer greater than or equal to 1 and less than N, and N is a positive integer.

It should be noted that, in the embodiment of this application, when the terminal searches the network for the i-th PLMN, it first searches for the standard under the i-th PLMN, and then searches for the frequency point or frequency band information corresponding to the standard, and then Search for signals based on the frequency or frequency band information.

In some embodiments of the present application, the terminal may not get the i-th signal, that is, the signal cannot be searched. At this time, if all the modes of the i-th PLMN cannot find the signal, it will start to check the i-th signal. +1 PLMN for network search processing.

S1032, parse out the i-th candidate PLMN from the i-th signal.

In the embodiment of this application, after the terminal obtains the i-th signal, the realization of analyzing the i-th candidate PLMN from the i-th signal may be: the terminal decodes the i-th signal obtained by searching the network to obtain network information-PLMN The number segment or label of, and the decoded PLMN is used as the i-th candidate PLMN.

It should be noted that if the terminal obtains the i-th signal by searching the network, the i-th signal carries information such as the PLMN number segment and frequency point information.

S1033. When the i-th candidate PLMN is inconsistent with the i-th PLMN, continue to search the network based on the i+1th PLMN until the i+Mth candidate PLMN consistent with the i+Mth PLMN is searched out, Take the i+Mth candidate PLMN as the target PLMN; where M is a positive integer greater than or equal to 1, and i+M is a positive integer less than N.

In the embodiment of the present application, after the terminal parses the i-th candidate PLMN, it compares the i-th candidate PLMN obtained by analyzing the i-th signal with the i-th PLMN to see whether the searched signal is correct. If the i-th candidate PLMN is inconsistent with the i-th PLMN, it means that the i-th candidate PLMN is not the required PLMN, and other PLMN signals are found under the i-th PLMN, indicating that the i-th signal is not intended to be searched That is, it is impossible to search the network in the i-th candidate PLMN.

In some embodiments of the present application, when the terminal does not search the network in the i-th PLMN, it needs to continue to search the network from the PLMN list for the i+1th PLMN whose network coverage is only lower than the i-th PLMN. First search for the standard under the i+1th PLMN, then search for the i+1th frequency point or i+1th frequency band information corresponding to the standard, and then search for the i+1th signal based on the frequency point or frequency band information. After analyzing the i+1th candidate PLMN, the terminal compares the i+1th candidate PLMN obtained by analyzing the i+1th signal with the i+1th PLMN to see if the searched signal is correct. The i+1th candidate PLMN is inconsistent with the i+1th PLMN, so it means that the i+1th candidate PLMN is not the required PLMN. The signals of other PLMNs are found under the i+1th PLMN, which represents the The i+1 signal is not the signal to be searched, that is, the network search cannot be realized in the i+1th candidate PLMN.

In the embodiment of this application, if the i+1th candidate PLMN decoded from the i+1th signal is not the required PLMN, the network coverage is only lower than the i+M-1th candidate PLMN from the PLMN list. The i+Mth PLMN of the PLMN is searched. If it is found that the i+Mth candidate PLMN is exactly the same as the i+Mth PLMN, it means that the i+Mth candidate PLMN is the required PLMN, that is, The signal of the corresponding PLMN is searched under the i+Mth PLMN, which indicates that the i+Mth signal is the signal that you want to search, that is, the network can be searched in the i+Mth candidate PLMN, and the i+Mth candidate PLMN can be searched. +M candidate PLMNs are used as target PLMNs.

It should be noted that when M=1, it means that the terminal has searched the network during the i+1th PLMN network search. M is greater than 1. The characterization end did not find the network when searching for the i+1th PLMN, and when continuing to search for the following PLMN, it found the network in the i+Mth PLMN.

S1034. When the i-th candidate PLMN is consistent with the i-th PLMN, use the i-th candidate PLMN as the target PLMN.

In the embodiment of this application, after the terminal parses the i-th candidate PLMN, it compares the i-th candidate PLMN decoded from the i-th signal with the i-th PLMN. If the i-th candidate PLMN happens to be the same as the i-th PLMN, The two PLMNs are completely consistent, indicating that the i-th candidate PLMN is the required PLMN, that is, the i-th candidate PLMN can enable the terminal to search the network and use the i-th candidate PLMN as the target PLMN.

In some embodiments of the present application, when the i-th candidate PLMN is consistent with the i-th PLMN, it means that the decoded network information of the i-th candidate PLMN corresponds to the network information required by the terminal to access the network, that is, The terminal can search the network through the i-th candidate candidate PLMN.

In the embodiment of this application, if the i-th candidate PLMN is inconsistent with the i-th PLMN, continue to search the network based on the i+1th PLMN until the i+Mth candidate consistent with the i+Mth PLMN is searched out PLMN, the i+M-th candidate PLMN is used as the target PLMN. At this time, the i+M-th PLMN in the PLMN list is used for network access; if the i-th candidate PLMN is consistent with the i-th PLMN, the If i candidate PLMNs are used as target PLMNs, the i-th PLMN in the PLMN list is used for network access.

In some embodiments of the present application, at least one PLMN includes a plurality of PLMNs arranged in sequence; based on the contracted network information, the target PLMN is determined, and according to the target PLMN, the realization of network access may be: the terminal is based on the at least one PLMN Search the network for the i-th PLMN of, and when the i-th signal is not obtained, continue to search the network based on the i+1th PLMN until the i+Mth candidate PLMN consistent with the i+Mth PLMN is searched , Take the i+Mth candidate PLMN as the target PLMN; where i is a positive integer greater than or equal to 1 and less than N, N is the total number of at least one PLMN; M is a positive integer greater than or equal to 1.

In the embodiment of this application, the terminal obtains the corresponding PLMN list based on the contracted network information, where the order of the multiple PLMNs included in the PLMN list is determined, and the PLMN list is arranged in descending order of network coverage , If the i-th PLMN is searched and the i-th signal is not obtained, the network will be searched based on the i+1-th PLMN according to the determined arrangement order. When the i+M-th PLMN is searched from the PLMN list The i+Mth candidate PLMN with the same PLMN, the i+Mth candidate PLMN is the target PLMN.

It should be noted that the PLMN list can also be arranged from small to large according to the network coverage. If it is arranged from small to large, the terminal determines the PLMN based on the contracted network information, and according to the target PLMN, the implementation process of network access can be Including: search the network based on the i-th PLMN in at least one PLMN to obtain the i-th signal; where i is a positive integer less than or equal to N, and N is the total number of at least one PLMN; and parse out the i-th signal from the i-th signal i candidate PLMN; when the i-th candidate PLMN is inconsistent with the i-th PLMN, continue to search the network based on the i-1th PLMN until the iM-th candidate PLMN consistent with the iM-th PLMN is searched, and The iMth candidate PLMN is used as the target PLMN; where M is a positive integer less than or equal to N-1, and iM is a positive integer greater than or equal to 1; finally, network access is performed according to the target PLMN.

Exemplarily, the fact that the i-th signal is not obtained indicates that the i-th PLMN in the PLMN list is not a target PLMN required by the terminal to search the network. For example, the network identifier of the PLMN of operator A is 33010, and the network identifier of the PLMN of operator B is 33020. Since the network coverage of operator A is larger than that of operator A, PLMN33010 is ranked before PLMN33020 in the PLMN list. When searching the network, the terminal first searches for PLMN33010, then the terminal searches for the system corresponding to PLMN33010, and obtains the frequency point information and frequency band information corresponding to the system; the terminal decodes the frequency point information, and the decoded network information corresponds to PLMN33010 Inconsistent, then PLMN33010 is not the target PLMN required by the terminal to search the network.

It should be noted that S1033 and S1034 are two optional implementations after S1032, which can be executed according to the actual implementation situation, and this application does not limit the execution order.

In some embodiments of the present application, as shown in FIG. 6, a flow chart of the i-th signal obtained by the terminal searching the i-th PLMN, the implementation of S1031 includes: S10311-S10315, as follows:

S10311: Search based on the standard corresponding to the i-th PLMN in at least one PLMN, and search for the target standard.

In the embodiment of the present application, when the terminal performs signal search or network search for the i-th PLMN in at least one PLMN, the search priority order is standard-frequency point information-frequency band information. The terminal first searches for the system corresponding to the i-th PLMN. The search is performed according to the priority of the system to obtain the target system, and then searches for the frequency information corresponding to the target system. If the frequency information cannot be found, Search for frequency band information corresponding to the target standard.

It should be noted that the contracted network information corresponding to the target communication card obtained by the terminal includes at least one PLMN, and at least one standard information, at least one frequency point information, and at least one frequency band information corresponding to the at least one PLMN. Therefore, the terminal is in After the target standard is determined, the frequency point information and frequency band information of the target standard can be determined from the contracted network information.

In the embodiment of the present application, when performing a network search, searching for the system corresponding to the i-th PLMN also needs to be searched in the order of the system search priority from high to low, where the system search priority is from high to low The order is: 4G (including frequency division duplex LTE (Frequency Division Duplexing LTE, FDD LTE) and time division duplex LTE (Time Division Long TERM, TD-LTE) two standards), 3G (including broadband code division multiple access) (Wideband Code Division Multiple Access, WCDMA) and Time Division-Synchronous Code Division Multiple Access (Time Division-Synchronous Code Division Multiple Access, TDSCDMA) two standards), 2G (including GSM and CDMA two standards).

In some embodiments of the present application, if the system corresponding to the PLMN is found to be 4G during the network search process, 4G is given priority as the target system corresponding to the i-th PLMN. If 4G is not found, 3G is found If this is the case, 3G will be prioritized as the target standard corresponding to the i-th PLMN.

It should be noted that different PLMNs correspond to different standards. For example, some PLMNs only have 5G, 4G, and 2G, but not 3G, while some PLMNs only have 5G and 3G, and 2G does not have 4G, and so on. Among them, the priority of the system corresponding to the same PLMN is sorted from high to low. If there is no 3G, the order of priority is: 5G, 4G, 2G; if there is no 4G, the order of priority is: 5G, 3G, 2G, the embodiment of this application does not limit it.

In some embodiments of the present application, if the terminal searches for the i-th PLMN according to the priority of the system, and no network or signal is found in the system with the highest priority, it continues to search for the system with the second highest priority until Search out the target system. However, if the standard is not found in the i-th PLMN, then the search for the next PLMN in the PLMN list is directly performed.

In the embodiment of the present application, after the target standard corresponding to the i-th PLMN is searched according to the priority order, the target frequency information corresponding to the target standard is further searched, where the target frequency information refers to a plurality of commonly used target standards corresponding to the target standard. Frequency information.

It should be noted that after the terminal determines the target standard according to the target PLMN, it needs to obtain frequency information corresponding to the target standard. Among them, different standards correspond to different frequency information, and there are multiple commonly used frequency information under the same target standard. .

Exemplarily, if the target standard of the i-th PLMN is 4G searched in the order of priority, the search is performed on the common frequency point corresponding to 4G. If the target standard of the i-th PLMN is 3G, then the common frequency corresponding to the i-th PLMN is 3G. The search is performed on the frequency point. Therefore, the priority search order of the frequency point information depends on the priority order of the target system.

S10313: If the network signal is searched from the target frequency point information, and the network signal is found, the network signal is taken as the i-th signal.

In the embodiment of the present application, if the target frequency point information under the target standard corresponding to the i-th PLMN is found, the target frequency point is scanned, and the scanned network signal is used as the i-th signal corresponding to the i-th PLMN.

Exemplarily, during the frequency point scanning process, the terminal will sort according to the energy value (ie power value) of each frequency point, and preferentially decode the frequency point with high energy value to obtain the decoded network information. Including: PLMN, frequency point number information, cell priority information and other basic network information.

In some embodiments of the present application, when the terminal determines the target frequency point information according to the target standard, it first scans the common frequency points under the target standard, then measures the power value of each common frequency point, and compares the common frequency points Sort the power values of, select the frequency point with the largest power value as the target frequency point information, and search the target frequency point information for the network signal. If the network signal is found, the network signal is taken as the i-th signal.

S10314. If the network signal is searched from the target frequency point information, and the network signal is not found, obtain the target frequency band information corresponding to the target standard from the frequency band information corresponding to the i-th PLMN.

In the embodiment of this application, in the process of searching the target frequency point information for the network signal, if none of the common frequency points included in the target frequency point has searched for energy information, that is, the received power information of the target frequency point is not searched, it is required Search for corresponding network signals in the frequency band information corresponding to the i-th PLMN.

Exemplarily, the search order of frequency band information is searched according to the search priority of the target standard of the i-th PLMN, that is, if the target standard is 4G, the frequency band information of 4G is searched first, and if the target standard is 3G, then 3G is correspondingly searched. Therefore, the priority search order of the frequency band information depends on the priority order of the target system.

In the embodiment of the present application, if the corresponding target frequency band information is obtained in the frequency band information corresponding to the i-th PLMN, the target frequency band information represents part of the frequency band information of the frequency band information corresponding to the i-th PLMN.

Exemplarily, when scanning the common frequency points included in the target frequency band information, if the corresponding frequency point information is not scanned, the frequency band information is selected from the frequency band information corresponding to the i-th PLMN as the target frequency band information, and Scan all frequency points included in the target frequency band information to search for network signals.

S10315. Search for network signals based on the target frequency band information, so as to obtain the i-th signal searched on the candidate target frequency point information, where the candidate target frequency point information is the frequency point information in the target frequency band information.

In the embodiment of the present application, all frequency points contained in the target frequency band information are scanned. If a frequency point with energy information is found during the scanning process, a network signal search is performed on this frequency point to obtain the i-th signal .

In some embodiments of the present application, the network information is obtained by decoding the i-th signal, and the network information includes basic information such as the network number PLMN, frequency point number, cell priority, etc., which is obtained by decoding the i-th signal PLMN is compared with the i-th PLMN. If the comparison results are consistent, it means that the network can be accessed at this frequency. On the contrary, if the comparison results are inconsistent, it means that the network cannot be accessed at this frequency and needs to be re-networked on other frequency bands. Signal search.

Exemplarily, suppose the target standard is 3G, and the supported frequency bands are B1, B2, B3, and other frequency bands. If all frequency points in the frequency band B1 do not have frequency points with energy information, that is, the corresponding network is not searched. Signal; in the next network search process, search for network signals in frequency bands that have not been searched except for frequency band B1, and use the searched network signal as the i-th signal.

It should be noted that S10313 and S10314 are the two optional implementations after S10312 and before S10315, which can be executed according to actual implementation conditions, and this application does not limit the execution order.

In the embodiment of the present application, a search is performed based on the standard corresponding to the i-th PLMN in at least one PLMN, and the target standard is searched; from the frequency information corresponding to the i-th PLMN, the target frequency information corresponding to the target standard is obtained; If the network signal is searched from the target frequency information, and the network signal is found, the network signal is regarded as the i-th signal; if the network signal is searched from the target frequency information and the network signal is not found, the i-th signal In the frequency band information corresponding to each PLMN, obtain the target frequency band information corresponding to the target standard; search for network signals based on the target frequency band information to obtain the i-th signal searched on the candidate target frequency point information, where the candidate target frequency point information Is the frequency point information in the target frequency band information. It can be seen that by searching the PLMN list included in the contracted network information, it is possible to avoid traversal search of PLMNs under all network information. At the same time, the target standard in the PLMN list is searched according to the priority, and the common frequency corresponding to the target standard Scanning does not need to scan all frequency points corresponding to the target standard, which can improve the search efficiency of the target PLMN, thereby shortening the network search time.

In the embodiment of this application, when the terminal does not search any network within a preset time as a system message, the terminal stops the current network search of MCC and PLMN, and the terminal searches for system messages in all supported frequency bands, and uses the searched system messages Determine the target MCC of the roaming destination, and the terminal can search for the target PLMN in a targeted manner through the contracted network information in the contracted network information database.
