and 102, selecting SNPN according to the associated information of the signed SNPN and the priority information of the associated information.

In order to enable the terminal to flexibly select the SNPN according to user preference (user preference) in the automatic SNPN selection mode, the embodiment of the invention sets the priority for the associated information of the signed SNPN, and the terminal selects the SNPN with the highest priority according to the priority of the associated information of each signed SNPN.

Alternatively, the priority of the associated information may be set by the terminal according to the user preference, and is not particularly limited herein.

a data network name DNN provided by the subscription SNPN;

connection Capability information (Connection Capability) provided by the subscribed SNPN; such as "ims", "mms", "internet", etc.;

and the information of the third party authentication entity supported by the signed SNPN.

When the associated information of the subscribed SNPN only includes any one of the above items of information, the target associated information of the subscribed SNPN is one item of information included in the associated information of the subscribed SNPN. For example, the association information of the subscribed SNPN includes: the target associated information of the signed SNPN is the identifier of the application provided by the signed SNPN; for another example, the association information of the subscribed SNPN includes: and if the address of the application server provided by the signed SNPN is the address of the application server provided by the signed SNPN, the target associated information of the signed SNPN is the address of the application server provided by the signed SNPN.

The step of performing SNPN selection according to the other available subscription SNPN associated information and the priority information of the associated information is the same as the step of performing SNPN selection in step 102 in the embodiment of the present invention, and detailed description thereof is not repeated here.

In order to more clearly describe the network selection method provided by the embodiment of the present invention, the following description is made with reference to several examples.

Example one: the related information of signed SNPN and the priority of the related information are stored in USIM

SNPN SELECTION information based on user intention is stored in the USIM, and a FILE name is assumed to be FILE _ SNPN _ SELECTION. The length of the FILE _ SNPN _ SELECTION is variable, and a maximum length, that is, the number of bytes, can be set.

For example, the FILE _ SNPN _ SELECTION content includes a plurality of primary directories, each of which includes:

SNPN association information, assuming name SNPN _ SELECTION _ IE. The associated information is used for SNPN selection according to the user intention.

SNPN ID lists, each SNPN ID list containing a plurality of secondary directories, i.e., SNPN IDs associated with SNPN _ SELECTION _ IE.

Table 1 shows the priority information of the association information of the subscribed SNPN.

Description of the invention	Status of state
		SNPN _ SELECTION _ IE1 (high priority)	M/O
SNPN1A (high priority)	M/O
		SNPN 1B	M/O
……	M/O
		SNPN_SELECTION_IE 2	O
SNPN 2A	O
		SNPN 2B	O
……	O
		SNPN _ SELECTION _ IE n (Low priority)	O
SNPN nA	O
		SNPN nB (Low priority)	O

TABLE 1

From top to bottom in table 1 indicates that the priority goes from high to low. For example, for SNPN _ SELECTION _ IE, SNPN _ SELECTION _ IE1 has the highest priority, SNPN _ SELECTION _ IEn has the lowest priority; for SNPN IDs in the same SNPN _ SELECTION _ IE, the first SNPN ID, i.e., SNPN aa, has the highest priority, and the priority gradually decreases from the first SNPN ID to the next SNPN ID.

As shown in fig. 2, when the terminal receives the SNPN ID from the air interface during network searching, that is, when a plurality of available subscribed SNPN networks are searched, the association information of the SNPN corresponding to the SNPN ID and the priority of the association information are queried from the USIM, and the SNPN with the highest priority is selected according to table 1.

When the SNPN _ SELECTION _ IE corresponding to the searched SNPN is different, for example, when the terminal searches SNPN1A and SNPN2B, the terminal selects to access SNPN1A according to the priority order in the table 1;

when the SNPN _ SELECTION _ IEs corresponding to the searched SNPNs are the same, for example, when the terminal searches SNPN1A and SNPN1B, the terminal selects access SNPN1A according to the priority order in table 1.

And when the USIM card signs with the operator, writing or updating the file corresponding to the table 1 into the USIM card.

Example two: the related information of the signed SNPN is stored in a user data list, and the priority information of the related information is stored in a USIM

The FILE _ SNPN _ SELECTION contains a list of association information with SNPN, assuming the name SNPN _ SELECTION _ IE. The associated information is used for SNPN selection according to the user intention. As shown in table 2.

Description of the invention	Status of state
		SNPN _ SELECTION _ IE1 (high priority)	M/O
SNPN_SELECTION_IE 2	O
		……	O
SNPN _ SELECTION _ IE n (Low priority)	O

TABLE 2

From top to bottom in table 2 indicates that the priority goes from high to low: for SNPN _ SELECTION _ IE, SNPN _ SELECTION _ IE1 has the highest priority and SNPN _ SELECTION _ IEn has the lowest priority.

The "user data list" includes the correlation information of a plurality of SNPNs, and for each SNPN, the correlation information of the SNPN is added to the "user data list", as shown in table 3.

TABLE 3

As shown in fig. 3, when the terminal receives the SNPN ID from the air interface in the network searching process, that is, when a plurality of available subscribed SNPN networks are searched, the correlation information of the searched SNPN is obtained according to table 3, and the SNPN corresponding to the highest priority is selected according to the priority of the correlation information in table 2.

For example, the SNPN IDs searched by the terminal are SNPN1 and SNPN2, the associated information corresponding to SNPN1 is SNPN _ SELECTION _ IE1 according to table 3, the associated information corresponding to SNPN2 is SNPN _ SELECTION _ IE2, and the terminal selects to access SNPN1 according to the priority order of SNPN _ SELECTION _ IEs in table 2 (the priority of SNPN _ SELECTION _ IE1 is higher).

And when the USIM card signs with the operator, writing or updating the file corresponding to the table 2 into the USIM card. The "user data list" may be updated by a registration acceptance, an in-vehicle universal communication unit UCU, or the like.

Example three: the priority of the related information of the signed SNPN is stored in USIM, and the related information of the SNPN is acquired from System Information (SIB)

The FILE _ SNPN _ SELECTION contains a list of association information with SNPN, assuming the name SNPN _ SELECTION _ IE. The associated information is used for SNPN selection according to the user intention. As shown in table 4.

TABLE 4

From top to bottom in table 4 indicates that the priority goes from high to low: for SNPN _ SELECTION _ IE, SNPN _ SELECTION _ IE1 has the highest priority and SNPN _ SELECTION _ IEn has the lowest priority.

As shown in fig. 4, in the network searching process of the terminal, the terminal receives the SNPN ID from the air interface, receives the association information of the SNPN from the system information (for example, the NG-RAN sends the association information of the SNPN to the terminal in the SIB), and the terminal selects the SNPN corresponding to the highest priority according to the received association information of the SNPN and the priority of the association information in table 4.

For example, when the terminal receives SNPN IDs of SNPN from the base station as SNPN1 and corresponding association information SNPN _ SELECTION _ IE1, SNPN2 and corresponding association information SNPN _ SELECTION _ IE2, the terminal selects to access SNPN1 according to the priority order of SNPN _ SELECTION _ IEs (SNPN _ SELECTION _ IE1) in table 4.

And when the USIM card signs with the operator, writing or updating the file corresponding to the table 4 into the USIM card.

In summary, in the embodiments of the present invention, when the terminal searches for a plurality of available subscribed SNPNs, the terminal performs SNPN selection according to the associated information of the subscribed SNPNs and the priority information of the associated information, so that the terminal can flexibly select the SNPN.
