The mobile communication network number is a number allocated to a mobile communication operator for identifying a mobile communication network operated by the mobile communication operator, for example, the mobile communication network number of china mobile is 46000, the mobile communication network number of china unicom is 46001, a base station broadcasts the mobile communication network number through a wireless interface, when a terminal needs to connect to a network, available mobile communication network numbers broadcasted by surrounding base stations are searched, and then a network access with the highest priority is selected from all available mobile communication network numbers according to the network priority built in the SIM card, if all the searched available mobile communication network numbers are not included in the network priority built in the SIM card, the terminal sequentially attempts to access each available mobile communication network until an accessible network is found (suitable for a roaming state), after the terminal accesses the mobile communication network, and displaying the corresponding operator name by inquiring the corresponding relation database of the mobile communication network number and the operator name stored by the mobile communication network number and the operator name.
With the gradual maturity of 5G technology, the use of 5G mobile communication networks gradually enters the head track, because the construction cost of 5G networks is high, in some areas, operators directly broadcast the mobile communication network number corresponding to the 5G network on the original base station without broadcasting the mobile communication network number corresponding to the 2/3/4G network, in some areas, the operators do not deploy their own network base stations but share the base stations of other operators, in addition, most existing users have fixed-use SIM cards and do not want to change, in this case, in the same place, the user's terminal often searches for more than two mobile communication network numbers, including the old mobile communication network number of the 4G network and the new mobile communication network number of the 5G network, because the mobile communication network number of the 4G is set as the highest priority in the original SIM card, the mobile communication network number of 5G is not configured in the priority list set by the original SIM card, so that the terminal can be preferentially logged in the 4G network and cannot be smoothly accessed to the 5G network, and the user experience is poor; in addition, in a region where networks of other operators are shared, after a user accesses a mobile communication network of the other operator, the name of the other operator is displayed on a mobile phone of the user, but the name of the home operator is not displayed, which is also disadvantageous to brand construction of the operators and affects user experience.

Example two
The present embodiment provides a method for a terminal to access a mobile communication network, as shown in fig. 2, the method includes:
step S201, searching for a first mobile communication network number of an accessible mobile communication network.
When a terminal needs to access a Mobile communication Network, the terminal searches for a currently available Mobile communication Network, specifically, the terminal searches for a currently available Mobile communication Network number, it should be noted that the Mobile communication Network number described in the present invention refers to a PLMN (Public Land Mobile Network) number, and each Mobile communication Network provided by an operator has a different Mobile communication Network number, that is, each of the 3G, 4G and 5G Mobile communication networks has a different Mobile communication Network number.
Step S202, judging whether the mobile communication network number corresponding to the 5G mobile communication network exists in all the first mobile communication network numbers.
In the invention, after all available mobile communication network numbers (first mobile communication network numbers) are obtained by searching, whether all the first mobile communication network numbers include the mobile communication network number corresponding to the 5G mobile communication network is judged so that the terminal can be preferentially considered to access the 5G mobile communication network.
In step S202, when it is determined that the mobile communication network number corresponding to the 5G mobile communication network does not exist in all the first mobile communication network numbers, the process proceeds to step S203'; when it is determined that the mobile communication network number corresponding to the 5G mobile communication network exists in all the first mobile communication network numbers, the process proceeds to step S203.
Step S203', detecting whether the priority list built in the SIM card contains at least one first mobile communication network number.
When detecting that the priority list includes at least one first mobile communication network number, executing step S204'; when it is detected that the first mobile communication network number is not included in the priority list, step S205' is performed.
Step S204', selecting the mobile communication network number with the highest priority from the at least one first mobile communication network number included in the priority list as the target mobile communication network number, so as to access the mobile communication network corresponding to the target mobile communication network number.
Step S205', sequentially try to access the network corresponding to each first mobile communication network number until a network corresponding to an accessible first mobile communication network number is found.
Steps S203 '-S205' are measures taken when the terminal determines that the mobile communication network number corresponding to the 5G mobile communication network does not exist in all the first mobile communication network numbers, specifically, when it determines that the mobile communication network number corresponding to the 5G mobile communication network does not exist in all the first mobile communication network numbers, it indicates that the terminal does not currently have an available 5G mobile communication network to access, at this time, the terminal selects a mobile communication network to access according to a conventional procedure for accessing the mobile communication network by the terminal, that is, the terminal selects a mobile communication network to access from the first mobile communication network numbers by referring to a priority list built in the SIM card.
In step S203, the mobile communication network number corresponding to the 5G mobile communication network in all the first mobile communication network numbers is identified as the second mobile communication network number.
Step S204, whether the priority list built in the SIM card contains at least one second mobile communication network number is detected.
When detecting that the second mobile communication network number is included in the priority list, executing step S205; when detecting that the second mobile communication network number is not included in the priority list, executing step S206;
step S205, according to the priority relationship of the priority list, selecting a second mobile communication network number with the highest priority from at least one second mobile communication network number included in the priority list as the target mobile communication network number, so as to access the mobile communication network corresponding to the target mobile communication network number.
Step S206, whether the pre-stored first peer-to-peer public mobile network list contains at least one second mobile communication network number is detected.
When detecting that the first peer-to-peer public mobile network list includes at least one second mobile communication network number, executing step S207; if it is detected that the first peer-to-peer public mobile network list does not include the second mobile communication network number, step S203' is further performed.
Step S207, selecting one of the at least one second mobile communication network number included in the first peer-to-peer public mobile network list as a target mobile communication network number to access the mobile communication network corresponding to the target mobile communication network number.
In this embodiment, when the terminal determines that the mobile communication network number corresponding to the 5G mobile communication network exists in all the first mobile communication network numbers, it first detects whether the priority list built in the SIM includes the searched 5G mobile communication network number (second mobile communication network number), if the priority list includes at least one second mobile communication network number, it selects an access from the at least one second mobile communication network number directly according to the priority relationship of the priority list, and if the priority list does not include the second mobile communication network number, it further detects a first equivalent public mobile network list stored in the terminal, where the first equivalent public mobile network list stores the mobile communication network provided by the operator to which the terminal belongs and the mobile communication networks provided by other sharable operators, when it is detected that the first peer-to-peer public mobile network list includes at least one second mobile communication network number, it indicates that the 5G mobile communication network number (second mobile communication network number) searched by the terminal includes a mobile communication network accessible by the user, and at this time, one second mobile communication network number may be selected to access.
In this embodiment, the first peer to peer public mobile network list stored in the terminal is issued by the operator network to which the terminal belongs, and is updated aperiodically, and in this embodiment, the first peer to peer public mobile network list is updated according to the following method:
(1) and when accessing the 3G or 4G network provided by the home operator, receiving a second peer-to-peer public mobile network list sent by the home operator network.
(2) And comparing whether the second peer public mobile network list is consistent with the stored first peer public mobile network list or not, if so, replacing the first peer public mobile network list with the second peer public mobile network list to complete the updating of the first peer public mobile network list, and if not, not updating the first peer public mobile network list.
The embodiment can ensure that the peer-to-peer public mobile network list stored in the terminal is up-to-date by updating the first peer-to-peer public mobile network list at irregular time, thereby ensuring that the terminal can be correctly and smoothly accessed into a legal 5G mobile communication network.
It should be noted that, in this embodiment, the manner of storing the first peer-to-peer public mobile network list in the terminal may be non-volatile storage (data is not lost after the terminal is powered off and restarted), or volatile storage (data is lost after the terminal is powered off and restarted), and when the storage manner is volatile storage, the terminal is firstly accessed to a 3G or 4G network provided by an affiliated operator to receive and store the peer-to-peer public mobile network list issued by the operator network at each time of powering on.
In this embodiment, when determining that the mobile communication network number corresponding to the 5G mobile communication network exists in all the first mobile communication network numbers, the method for accessing the mobile communication network by the terminal according to the second mobile communication network number can enable a user who has replaced a SIM card (for example, a SIM card replaced with a 5G SIM card) to quickly access the 5G mobile communication network according to a conventional procedure for accessing the mobile communication network (according to the priority list built in the SIM card) by first detecting whether the mobile communication network number includes at least one second mobile communication network number in the priority list built in the SIM card, and further search for whether the second mobile communication network number includes at least one second mobile communication network number from the stored first peer public mobile network list when the second mobile communication network number does not include the priority list built in the SIM card, so as to ensure that the user who does not replace the SIM card can smoothly access the 5G mobile communication network in time Under the condition that the 3G, 4G and 5G networks coexist, the 5G network is accessed in priority smoothly, so that the user experience is higher.
Step S208, inquiring the first peer-to-peer public mobile network list according to the target mobile communication network number to determine whether the first peer-to-peer public mobile network list contains the target mobile communication network number.
When it is determined that the first peer-to-peer public mobile network list includes the target mobile communication network number, step S209 is executed; when it is determined that the first peer to peer public mobile network list does not include the target mobile communication network number, step S210 is performed.
Step S209 displays the operator name of the operator to which the mobile terminal belongs.
Step S210, according to the target mobile communication network number, querying from the mobile communication network database of the mobile communication network to determine a target operator name corresponding to the target mobile communication network number, and displaying the target operator name.
Steps S208 to S210 are steps of displaying the name of the operator after the terminal accesses the mobile communication network.
In this embodiment, when displaying the name of the operator, first determining whether the target Mobile communication network number of the accessed target Mobile communication network exists in a first equivalent public Mobile network list stored in the terminal, and when querying that the first equivalent public Mobile network list contains the target Mobile communication network number, it indicates that the target Mobile communication network accessed by the terminal is a 5G Mobile communication network, and at this time, the target Mobile communication network is either a 5G Mobile communication network provided by the operator to which the terminal belongs or a 5G Mobile communication network of another operator shared by the operators to which the terminal belongs, and at this time, to enhance brand construction, the terminal should display the name of the operator to which the terminal belongs, specifically, the terminal first obtains the Mobile communication network number (IMSI number (International Mobile Subscriber Identity, international mobile subscriber identity), and further performs query from a mobile communication network database stored in the mobile communication network database according to the acquired mobile communication network number of the home operator to acquire the name of the home operator, and further displays the name of the home operator, wherein the mobile communication network database stores the corresponding relationship between the global mobile communication network number and the name of the operator, and the mobile communication network number and the name of the operator are stored in advance by the terminal.
And when the first equivalent public mobile network list is inquired to contain no target mobile communication network number, the target mobile communication network number is accessed to the mobile communication network according to the conventional mobile communication network access process, and at the moment, the mobile communication network database stored by the target mobile communication network number is directly inquired according to the target mobile communication network number, so that the correct operator name corresponding to the target mobile communication network can be obtained.
