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: association information of subscription SNPN and priority of association information are stored in USIM

SNPN SELECTION information based on user will is stored in the USIM, and the FILE name is assumed to be FILE_SNPN_SELECTION. The file_snpn_select length is a variable length, and a maximum length, i.e., number of bytes, may be set.

For example, the contents of the file_snpn_select contain a plurality of primary directories, each primary directory containing:

the association information of SNPN is assumed to be named SNPN_SELECTION_IE. The association information is used for SNPN selection according to user wish.

SNPN ID lists, each containing a plurality of secondary directories, namely SNPN IDs associated with SNPN_SELECTION_IE.

The priority information of the association information of the contracted SNPN is shown in table 1.

Description of the invention	Status of
		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_IEn (Low priority)	O
SNPN nA	O
		SNPN nB (Low priority)	O

TABLE 1

The priority is shown from high to low from top to bottom in table 1. For example, for the SNPN_SELECTION_IE, SNPN_SELECTION_IE1 has the highest priority and SNPN_SELECTION_IEn has the lowest priority; for the SNPN IDs in the same SNPN_SELECTION_IE, the first SNPN ID, i.e., SNPN A, has the highest priority, and the backward priority gradually decreases.

As shown in fig. 2, when a terminal receives a SNPN ID from an air interface in the network searching process, that is, searches for a plurality of available subscribed SNPN networks, related information of the SNPN corresponding to the SNPN ID and the priority of the related 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, selecting to access SNPN1A according to the priority sequence in the table 1;

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

When signing up with the operator, the files corresponding to the table 1 are written into or updated in 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 the USIM

The FILE file_snpn_select contains a list of association information with SNPN, assuming the name snpn_select_ie. The association information is used for SNPN selection according to user wish. As shown in table 2.

Description of the invention	Status of
		SNPN_SELECTION_IE1 (high priority)	M/O
SNPN_SELECTION_IE 2	O
		……	O
SNPN_SELECTION_IEn (Low priority)	O

TABLE 2

Table 2 shows the priority from high to low from top to bottom: for the SNPN_SELECTION_IE, SNPN_SELECTION_IE1 has the highest priority and SNPN_SELECTION_IEn has the lowest priority.

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

TABLE 3 Table 3

As shown in fig. 3, when the terminal receives the SNPN IDs from the air interface in the network searching process, that is, searches for a plurality of available subscribed SNPN networks, the association information of the searched SNPNs is obtained according to table 3, and at the same time, the SNPN corresponding to the highest priority is selected according to the priority of the association information in table 2.

For example, the terminal searches for the SNPN IDs of SNPN1 and SNPN2, obtains the association information corresponding to the SNPN1 as snpn_selection_ie1 according to table 3, obtains the association information corresponding to the SNPN2 as snpn_selection_ie2, and selects to access the SNPN1 according to the priority order of the snpn_selection_ie in table 2 (the priority of the snpn_selection_ie1 is higher).

When signing up with the operator, the files corresponding to the table 2 are written into or updated in the USIM card. The "user data list" may be updated by registration acceptance, the in-vehicle universal communication unit UCU, or the like.

Example three: priority of association information of subscription SNPN is stored in USIM, and association information of SNPN is obtained from System Information (SIB)

The FILE file_snpn_select contains a list of association information with SNPN, assuming the name snpn_select_ie. The association information is used for SNPN selection according to user wish. As shown in table 4.

TABLE 4 Table 4

Table 4 shows the priority from high to low from top to bottom: for the 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 issues the association information of the SNPN to the terminal in the SIB), and 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 the ID of the SNPN from the base station as SNPN1 and corresponding association information snpn_selection_ie1, SNPN2 and corresponding association information snpn_selection_ie2, respectively, the terminal selects to access SNPN1 according to the priority order of the snpn_selection_ie (snpn_selection_ie1) in table 4.

When signing up with the operator, the files corresponding to table 4 are written or updated into the USIM card.

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