Detailed ways

Embodiment one

This embodiment provides a method for generating a WLAN access state event, and the execution subject of the method in this embodiment may be a mobile terminal, such as a mobile phone, a tablet computer, and the like. The methods provided in this embodiment are all applied to a network architecture where WLAN and mobile network converged networking, that is, a network architecture of I-WLAN.

Before executing the method provided in this embodiment, it includes: obtaining the access state of the WLAN, and when the access state of the WLAN changes, execute the method provided in this embodiment, wherein FIG. 1 is the method provided in Embodiment 1 of the present invention The flowchart of the generation method of WLAN access state event, as shown in Figure 1, the generation method of this WLAN access state event comprises:

Step 101, obtain the specific identifier WSID (WLAN Specific Identifier, WSID for short) of the currently accessed WLAN and the WSID list information stored in the USIM card.

Specifically, the WSID list information is stored in a dedicated file DF (Dedicated File, DF for short) of the USIM card.

In addition, the terminal obtains the WSID list information stored in the USIM card through the interface between the terminal and the USIM card.

Step 102, judge whether the WSID list information stored in the USIM card contains an identifier consistent with the currently accessed WSID, and generate a first identifier result according to the judgment result.

Optionally, the WSID list information includes: any one or more of user WSID list information, operator WSID list information, and home WSID list information.

Generally speaking, the user and the operator can each maintain a list allowing access of the USIM card, that is, user WSID list information and operator WSID list information respectively.

In this embodiment, the WSID list information includes user WSID list information, operator WSID list information, and attribution WSID list information as an example for illustration. The first identification result should include identification bits representing the three comparison results. Specifically, the data object It should include the first identification bit, the second identification bit and the third identification bit.

Optionally, the first identification bit is used to identify whether the user WSID list includes an identification consistent with the WSID of the currently accessed WLAN, and the second identification bit is used to identify whether the operator WSID list includes an identification consistent with the currently accessed WLAN. An identifier of the same WSID, the third identifier bit is used to identify whether the attributable WSID list includes the identifier consistent with the WSID of the currently accessed WLAN.

For example, when the user WSID list includes an identifier consistent with the WSID of the currently accessed WLAN, the first identifier bit may be marked as 1; if the user WSID list does not include an identifier consistent with the WSID of the currently accessed WLAN, Then the first identification bit can be identified as 0;

A data object of the WLAN access state event is generated according to the second identification result for downloading by the USIM.

Among them, after the USIM downloads the data object, it can make corresponding decisions based on the information contained in the data object. For example, for the operator's WSID, it can be used to collect and count user access conditions and analyze user behavior. , or as a reference for WSID deployment, such as access management and policy control, requiring users to switch to allowed or specified WSIDs.

However, in the prior art, the terminal does not provide the above data to the USIM. In the method for generating the WLAN access state event provided in this embodiment, by judging whether the WSID list information stored in the USIM card contains the WSID consistent with the currently accessed WSID The first identification result is generated according to the judgment result, and the data object is generated according to the first identification result for downloading by the USIM, which can provide a basis for the development of subsequent services.
