Among them, the SIM card 103 stores the access parameters required by the user to access the interworking scenario 2 and the interworking scenario 3 under each PLMN that can be selected by the user, and set the identifier of each PLMN and each interworking mode The corresponding relationship table, as shown in Table 1: priority information field Intercommunication methods (in order of priority) pointer 1 Attribution PLMN ID scene 2 0x1111 2 Attribution PLMN ID Recommended interworking scenario: Scenario 3 0x2222 3 Recommended PLMN1 logo scene 3 0x1234 4 Recommended PLMN1 logo Recommended interworking scenario: Scenario 2 0x1248 5 Recommended PLMN2 logo scene 2 0x1256 6 Recommended PLMN2 logo Recommended interworking scenario: Scenario 3 0x1288

Table 1

The information stored in Table 1 includes: all PLMN identifiers and interworking mode identifiers that can be selected by the user, sorted according to the priority selected by the user or specified by the operator, and stored in the storage area of the SIM card indicated by the pointer.

The first and second entries in Table 1 are the relevant parameters required by the two interworking scenarios that the user can choose in the home PLMN, including: the identification of the user's home PLMN and the identification of interworking scenarios 2 and 3, where the user belongs to The identification of PLMN is represented by Mobile Country Code + Mobile Network Code (MCC+MNC). It is assumed here that interworking scenario 2 is the default interworking scenario specified by the user or network operator, so its priority is set to the highest, that is, 1, and the priority of interworking scenario 3 is set to 2.

The third and fourth entries are related parameters required by the user in one of the PLMNs recommended by the user, that is, the two interworking scenarios that can be selected in PLMN1, including: the identification of the user's home PLMN and the identification of interworking scenarios 2 and 3, wherein, The identity of the user's home PLMN is represented by the mobile country code + mobile network code (MCC+MNC).

Corresponding to Table 1, another table needs to be set in the SIM card for the user to choose the way to access the PDN. mode pointer 0 0x1111 0 0x2222 1 0x1248 1 0x1238 2 0x1256 2 0x1288

Table 2

Mode 0 in Table 2 indicates the home network, mode 1 indicates the recommended PLMN1, and mode 2 indicates the recommended PLMN2. The parameters stored in Table 2 can be manually modified by the user through the keyboard, or can be modified by the operator through the air interface, that is, WLAN TX/RX 104, in a short message (SMS) type 2, etc. mode.

For the selection of PLMN, it can be selected by the user through keyboard input, or when the mobile terminal accesses the PLMN, the mobile terminal can automatically select according to the set priority according to the information such as the network identification of the PLMN obtained from the air interface.

When the user enters mode 0 through the keyboard or automatically selects mode 0 through the mobile terminal, the mobile terminal will provide the user with two choices through the display screen: interworking scene 2 and interworking scene 3. In Table 1, the default interworking mode adopts scenario 2, and the recommended interworking mode adopts scenario 3. If the user does not intervene, according to the predefined default mode in Table 1, the CPU of the user's mobile terminal will automatically select scenario 2, and according to the access authentication parameters corresponding to the identifier, the WLAN TX/RX and WLAN interface in the mobile terminal will The network access sends an access authentication request message belonging to the interworking scenario 2 under the PLMN to the authentication center of the 3GPP network. The authentication request message includes authentication parameters such as user identification. If the authentication center successfully authenticates the user, it sends the mobile terminal The corresponding message of success is returned. After the mobile terminal receives the message through its own WLAN TX/RX, the user's mobile terminal can access the PDN through the interworking scenario 2. Users can also choose to use scenario 2 or scenario 3.

When the user is outside the coverage area of the home PLMN but in the area covered by PLMN1 and PLMN2, the user can reselect the PLMN to access, or the user's mobile terminal is detected by the WLAN TX/RX104, and according to the PLMN and intercommunication scenarios stored in the SIM card 103 The parameter automatically selects the interworking scenario 3 and interworking scenario 2 of the PLMN1 network with a higher recommended priority. If the user does not intervene, the default interworking scenario 3 will be automatically selected according to the user's mobile terminal. The user can also manually select interworking scenario 2 under PLMN1.

When the user's mobile terminal is not in PLMN1, the WLAN card of the user's mobile terminal will automatically select interworking scenario 2 and interworking scenario 3 of the recommended PLMN2 network according to the interworking scenario parameters stored in the SIM card 103 . If the user does not intervene, the default interworking scenario 2 will be automatically selected according to the user's mobile terminal. The user can also manually select interworking scenario 3 under PLMN2.
