Background technique

At present, the commonly used WLAN access method is: first collect cellular network coverage information and WLAN local area network coverage information, wherein the above-mentioned cellular network mainly includes 2G (such as GSM, CDMA95, etc.), 3G (such as WCDMA, CDMA2000, TDSCDMA, etc.), 4G (such as LTE, WIMAX, UMB, etc.); after that, the terminal uses the cellular network information received in the current area to determine whether there is effective WLAN coverage in the current area according to the collected cellular network coverage information and WLAN coverage information. If so, Then, according to the WLAN signal strength of the current area, it is determined whether to access the station covered by the effective WLAN. In this method, the collection of cellular network coverage information and WLAN coverage information may be performed by the terminal itself alone, or may be simultaneously participated by multiple other terminals.

In the above method, although WLAN access can be discovered, since the above-mentioned cellular network coverage information and WLAN coverage information are collected by the terminal itself or other multiple terminals, this cannot guarantee the comprehensiveness and timely coverage of the cellular network and WLAN coverage information. reliability, because only operators can have complete and reliable cellular network coverage information and WLAN coverage information. In addition, due to the large coverage of the cellular network, usually hundreds of meters or even thousands of meters, and the relatively small coverage of the WLAN local area network, usually tens of meters, there is a big difference between the two. Judging whether there is effective WLAN coverage in the area based on the information of a cellular network will cause large judgment errors. In addition, the above method is to determine whether to access the site in the effective WLAN coverage according to the WLAN signal strength of the current area. When a terminal accesses a site with relatively good WLAN signal strength but does not have login permission, the access fails.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The method provided by the present invention includes the process shown in FIG. 1 .

Referring to FIG. 1 , FIG. 1 is a flowchart of a method provided by an embodiment of the present invention. The method is applied to a multi-mode terminal supporting a cellular network and a WLAN (referred to as a CELL/WLAN multi-mode terminal). As shown in Figure 1, the method may include the following steps:

Step 101, the CELL/WLAN multi-mode terminal acquires cellular network coverage information and WLAN coverage information from a service station, and associates the acquired cellular network coverage information with the WLAN coverage information.

The cellular network coverage information and WLAN coverage information in the service desk are set by the operator, which is usually responsible for updating and storing the cellular network coverage information and WLAN coverage information all over the country. Therefore, in this step 101, the CELL/WLAN multimode terminal starts from The service desk acquires cellular network coverage information and WLAN coverage information, which can ensure that the obtained cellular network coverage information and WLAN coverage information are comprehensive, timely and reliable.

In addition, since the service desk is responsible for updating and storing the cellular network coverage information and WLAN coverage information all over the country, in order to save storage space, the CELL/WLAN multimode terminal can only obtain the cellular network coverage information and WLAN coverage information under its location. When roaming to another place, the cellular network coverage information and WLAN coverage information of the roaming place can be obtained from the service station through OTA, which is described below.

Among them, the above-mentioned cellular network coverage information mainly includes: cell identification information (such as LAC+CELLID of GSM network), site type (such as outdoor macro site, cellular network indoor site, etc.) and site name, site GPS location information, base station identification Correspondence between etc.;

WLAN coverage information mainly includes: site (AP) name, GPS location information of the site, service set identifier (SSID) of the site, MAC address, and the like.

Based on the content contained in the cellular network coverage information and WLAN coverage information described above, it can be seen that the cellular network coverage information and the WLAN coverage information are associated, and at least one content contained in both can be used as a link to link the two. . For example, the present invention does not specifically limit the site name, site GPS geographic location information, building identification, coverage area having an equivalent relationship between the cellular network coverage information and the WLAN coverage information, and the like. Wherein, the link for associating the coverage information of the cellular network and the coverage information of the WLAN is referred to as association logic for short, which can be acquired by the CELL/WLAN multimode terminal from the service desk.

In this way, through step 101, the CELL/WLAN multi-mode terminal can obtain the cellular network coverage information and the WLAN coverage information from the operator, and can also associate the cellular network coverage information with the WLAN coverage information.

Step 102, the CELL/WLAN multi-mode terminal determines whether the current location is covered by an indoor station of the cellular network, and if so, executes step 103.

Because WLAN is mainly deployed according to site APs, it is generally deployed indoors, such as office buildings, commercial centers, hotels, stations, etc., while cellular networks are generally covered by indoor distribution systems. This indoor distribution system is different from outdoor macro stations. The coverage area is relatively small compared to the outdoor macro station, which can provide relatively high-precision positioning. Based on this, in order to realize the discovery of WLAN coverage, this step 102 only assumes that the current position of the CELL/WLAN multimode terminal is covered by the cellular network indoor station. example. As for the process when the current location of the multi-mode terminal is covered by the outdoor station, in order to achieve the purpose of discovering WLAN coverage, the process when the current location of the CELL/WLAN multi-mode terminal is covered by the indoor station can be used, and details will not be repeated here.

In addition, in this step 102, the CELL/WLAN multi-mode terminal determines whether the current location is covered by the cellular network indoor station mainly based on the acquired cellular network coverage information and the currently received cellular network information, wherein the cellular network information It includes: identification information of the cell currently located, identification information of the adjacent cell, at least one of the base station identifier of the cell currently located and the base station identifier of the adjacent cell. For example, the current cell identification information is cell 1, and the identification information of neighboring cells is cell 2 and cell 3. In this way, the CELL/WLAN multimode terminal obtains cell 1, cell 2, and The GPS geographic location information of the station corresponding to the cell 3 is used to determine the current address and location information of itself (that is, a certain location in the cell 1), and then the type of the station corresponding to the determined location information is obtained from the cellular network coverage information, such as If the station is an indoor station of a cellular network, it is determined that the current location is covered by an indoor station of a cellular network; otherwise, it is determined that the current location is covered by an outdoor macro station.

It should be noted that step 102 is executed when WLAN coverage discovery is triggered. Wherein, the WLAN coverage discovery trigger includes at least one of the following conditions:

Condition 1: The user opens and uses the service client supporting WLAN and cellular network in the multi-mode terminal;

Condition 2: The cellular network data link signal used by the user is attenuated;

Condition 3: The data transmission speed based on the cellular network is lower than the set threshold;

Condition 4: The preset WLAN coverage discovery timer expires.

Step 103, the multi-mode terminal determines whether the current location is within the effective coverage of the WLAN according to the association relationship between the cellular network coverage information and the WLAN coverage information, and if so, executes step 104.

The determination in this step 103 specifically includes: the CELL/WLAN multimode terminal determines the WLAN coverage information associated with the cellular network indoor station used to cover the current location, and determines whether the current location is in a valid WLAN based on the determined WLAN coverage information. Within the coverage, for example, if the distance between the current location and the GPS geographic location information of the station in the determined WLAN coverage information is less than the set distance, it is determined that the current location is covered by a valid WLANAP; otherwise, it is determined that the current location is not covered by a valid WLANAP cover.

Preferably, in step 103, if the determination result is no, the current process may end.

Step 104, obtain the SSID and/or MAC address of the station in the effective WLAN coverage information from the WLAN coverage information, turn on the WLAN switch configured by itself, and use the opened WLAN switch to identify and access the station with the SSID and/or MAC address. address of the site.

So far, the process shown in FIG. 1 is completed.

It should be noted that, in the above step 101, the cellular network coverage information and WLAN coverage information acquired by the CELL/WLAN multimode terminal from the service station, and the association logic for associating the cellular network coverage information and WLAN coverage information are actively provided by the service station. Pushed, and/or pushed when the service desk receives a request from a CELL/WLAN multimode terminal. Specifically as shown in Figure 2

Wherein, the service station actively pushes the cellular network coverage information and WLAN coverage information, and the operation of the associated logic is performed periodically, and/or the cellular network coverage information changes, and/or the associated logic changes, and/or the WLAN coverage information changes when executed.
