A mobile phone card, including but not limited to SIM (subscriber identity module), USIM (universal subscriber identity module), RUIM (removable user identity module), UIM (user identity module), and the like.

Fig. 1 illustrates a wireless communication system, and the system illustrated in fig. 1 is merely an illustrative example. The wireless communication system comprises user equipment 11, a server 10 and a base station 13.

The user equipment 11 may communicate using one or more RATs. E.g., LTE, WCDMA, CDMA2000, TD-SCDMA, GSM, CDMA, etc.

The server 10 is used for providing a data statistics analysis service for the UE, and the server 10 may be provided by a producer or a seller of the UE, or may be provided by a developer of an operating system or an application installed in the UE.

The user equipment 11 may be connected to the Internet (Internet) through WIFI (WIreless Fidelity) or a data network, so as to establish a communication connection with the server 10 for data interaction. The user equipment 11 may access the mobile communications network through the base station 13.

In the embodiment of the invention, the UE monitors the character information loaded and displayed in the application program interface of the local machine and identifies one or more pieces of position information from the character information, and the shared PLMN list constructed by the server side is obtained according to the position information, so that the network access efficiency can be improved when the local machine enters a roaming state at the position information.

For the user equipment 11, an embodiment of the present invention provides a communication network access method, as shown in fig. 2, which includes the following steps.

And S20, acquiring the character information loaded and displayed in the local application program interface and identifying one or more position information from the character information.

And monitoring the character information loaded and displayed on the interface of the local application program through a preset program process, and identifying the position information from the character information.

The location information may be country, city, station, airport, etc. The location information may be the current location of the user equipment or a location that the user equipment will arrive at in a future period of time.

S21, uploading one or more position information to the server side so that the server side can construct a shared PLMN list; the shared PLMN list comprises PLMN identifications corresponding to one or more pieces of location information; the shared PLMN list is any one of an OPLMN list, a UPLMN list, a PPLMN list, an EPLMN list, and an EHPLMN list.

The position information can correspond to the PLMN, and the server builds a shared PLMN list related to the identified position information according to the corresponding relation.

The data in the shared PLMN list is obtained by the server side through statistical analysis of network access data uploaded by a plurality of UEs.

The network access data includes, but is not limited to, information such as operator (Carrier), PLMN, RAT, frequency point (Freq), location code (area code), Cell (Cell), MAC address, latitude and longitude.

The server collects network access data uploaded by a plurality of UE, and performs statistical analysis on communication network access information at different positions to obtain information such as PLMN, RAT, frequency point, cell and the like of the communication network accessible at each position. The shared PLMN lists are generated separately for different locations. For a location, the more network access data the server collects, the higher the accuracy of the shared PLMN list.

And S22, receiving the shared PLMN list returned by the server, and updating the PLMN list corresponding to the server.

After acquiring the shared PLMN list, the user equipment judges whether the PLMN identification in the shared PLMN list exists in the PLMN list corresponding to the local machine, adds the PLMN identification which does not exist in the PLMN list corresponding to the local machine to the PLMN list corresponding to the local machine, and completes the update of the PLMN list corresponding to the local machine.

The PLMN list updated by the ue corresponds to the shared PLMN list acquired from the server, and may be any one of an OPLMN list, a UPLMN list, a PPLMN list, an EPLMN list, and an EHPLMN list.

And S23, when the roaming state of the mobile phone is identified, searching the network according to the updated PLMN list and completing the network access.

The user equipment can identify whether the user equipment is in international roaming or not according to whether the MCC of the local communication network is changed or not, or identify whether the user equipment is in national roaming or not according to the position code.

For example, the non-access stratum (NAS) layer issues RPLMN high priority RAT registration; layer 1(Layer1, L1), i.e. the physical Layer, searches the RPLMN network according to the fast search frequency point table to generate an available network list, and if the MCC in the available network list is different from the MCC in the RPLMN, the network list indicates a roaming place; and informing the NAS, and the NAS acquires the PLMN registration corresponding to the new MCC in the updated PLMN list in the mobile phone card.

After the roaming state is identified, the network is not searched through the RPLMN in the memory any more, and the network search is carried out according to the updated PLMN list and the access is completed. Therefore, the process of scanning all frequency bands of various RATs stored in the RPLMN is skipped, unnecessary PLMN registration time is avoided, the speed of starting up and searching a registration network in a roaming state is increased, and the experience of a multi-mode terminal user is improved.

In one embodiment, the obtaining text information loaded and displayed in the local application program interface and identifying one or more position information from the text information includes:

identifying one or more position information from the text information of the mobile phone short message or the instant communication message; or identifying one or more position information from the character information loaded and displayed on the schedule application program interface; or identifying one or more position information from the character information loaded and displayed by the ticket class application program interface. The position information is recognized from the text information displayed on the application program interface so as to acquire the shared PLMN list.

In the above embodiment, the identification of one or more position information may be a rough identification, i.e. the position information of the occurrence in the text information is identified.

In yet another embodiment, the obtaining text information loaded and displayed in the local application program interface and identifying one or more location information from the text information includes: the method comprises the steps of obtaining character information loaded and displayed in a local application program interface and identifying destination information or travel information from the character information.

Here, the text information is more accurately recognized, and the destination of the user, or the travel information (including a plurality of destinations) in a future period of time, and the like can be recognized through semantic analysis. The method and the device realize more accurate identification of the position information, and can improve the speed of accessing the local communication network by utilizing the matched shared PLMN list when the identified position of the UE enters a roaming state.

In the above embodiments of the present invention, the shared PLMN list may include PLMN identifications of one or more countries, for example, as shown in the following table:

PLMN
	45403
45404
	……
46000

different PLMN identities are from different operators locally, and in order to further improve the hit rate of PLMN identities, in another embodiment the shared PLMN list comprises PLMN identities of visited operators that have signed roaming agreements with the operator to which the handset card of the user equipment belongs. The shared PLMN list is obtained by the server side through statistical analysis according to network access data uploaded by a plurality of UEs.

In the international roaming state, the user equipment directly inquires the PLMN identification of the visited operator signing a roaming agreement with the operator to which the mobile phone card belongs from the shared PLMN list through the MCC in the available network list and completes network access, so that the process of respectively trying the PLMN identifications of different operators under the same MCC is omitted, and the speed of starting up and searching for a registered network in the roaming state is further improved.

After determining the accessed PLMN, the UE continues to attempt registration according to RAT priorities, and rejects a certain number of times before attempting a RAT of lower priority, in order to further improve the access efficiency of the communication network, in another embodiment, the shared PLMN list further includes one or more RATs corresponding to each PLMN identifier, where the one or more RATs are obtained by the service end after performing statistical processing on network access data uploaded by the plurality of terminals and are RATs that have opened roaming service under corresponding PLMN identifiers.

Sometimes, some operators do not subscribe to roaming services of high priority RATs, e.g., LTE and WCDMA do not subscribe to roaming services, and GSM subscribes to roaming services. Then, LTE and WCDMA with high priority are not recorded under PLMN identity, and only GSM that opens roaming service is recorded. When the UE tries to access the RAT, the UE directly tries GSM and does not try to register LTE and WCDMA which do not open roaming service, thereby reducing unnecessary searching and time for trying to register. If the priority of the RAT signing the roaming service is improved by the subsequent operator, the shared PLMN list can be updated by the server through the collection of the network access data of each UE, and the RAT with the higher priority newly signed is added. The shared PLMN list in this embodiment is shown in the following table:

PLMN	RAT
		45403	LTE
	WCDMA
		45404	GSM
……	……
		46000	TD-SCDMA
	GSM
		46001	GSM

the shared PLMN list comprises one or more RATs corresponding to each PLMN identification, wherein the one or more RATs are obtained by the server through statistical processing of network access data uploaded by a plurality of terminals and are the RATs of which roaming services have been opened under the corresponding PLMN identification.

After determining the RAT attempting to access, the UE may scan each frequency Band (Band) corresponding to the RAT, where frequency points under each frequency Band are very many, and it takes much time to scan each frequency point. Therefore, in another embodiment, in order to further improve the communication network access efficiency, the shared PLMN list further includes one or more pieces of frequency point information corresponding to each RAT, where the one or more pieces of frequency point information are obtained by the server through statistical processing of network access data uploaded by the plurality of terminals, and are the pieces of frequency point information whose access probability under the corresponding RAT is greater than or equal to the preset threshold.

When the server side carries out statistical analysis on network access data, the server side carries out statistics on the information of the frequency points accessed by the UE in the roaming state at each position, the probability of the UE successfully accessing the frequency points is determined to be higher, the frequency points with the access probability larger than a preset threshold (for example, 50%) are recorded under the corresponding RAT in the shared PLMN list, and the information of the frequency points can be further sequenced from high to low according to the access probability. The shared PLMN list in this embodiment is shown in the following table:

PLMN	RAT	Freq
			45403	LTE	1750
		1825
					100
45403	WCDMA	10633
					10713
45404	GSM	935
			……	……	……
46000	TD-SCDMA	1889
					2011
46000	GSM	945
			46001	GSM	910
