The technical solution of the present invention will be described below by way of more specific embodiments. 4 is a schematic flowchart of Embodiment 4 of a method for obtaining WiFi access point information according to the present invention. In this embodiment, a base station is assumed to be a BTS (Base Transceiver Station) in a CDMA network, and a WiFi access point is an AP (Access Point). ), the terminal is a dual mode terminal supporting CDMA network and WiFi network. The method of this embodiment specifically includes the following steps: Step 401: The terminal sends a registration request message to the BTS, where the registration request message includes a target of the terminal; Step 402: After receiving the registration request message of the terminal, the BTS searches for the identifier of the cell where the terminal is located according to the identifier of the terminal, for example, the Sector ID. Step 403: The BTS sends the identifier of the terminal and the discovered Sector ID to the core network device.

The BTS may send the identifier of the terminal and the found Sector ID to the BSC; or the BTS may send the identifier of the terminal and the found Sector ID to the BSC, and then

The BSC forwards it to the PDSN.

Step 404: The core network device acquires an AP of a cell where the terminal is located according to the Sector ID. The core network device stores the corresponding relationship between the sector ID of each cell and the AP in the cell. Therefore, the core network device can find the AP in the corresponding cell according to the Sector ID. There may be one or more APs existing in the cell corresponding to the Sector ID.

In step 404, the BSC may obtain the AP of the cell in which the terminal is located according to the Sector ID. If the BSC forwards the identifier of the terminal and the discovered Sector ID to the PDSN, the step 404 may also be performed by the PDSN according to the Sector. The ID acquires the AP of the cell where the terminal is located. Optionally, before performing step 404, the core network device may determine, according to the identifier of the terminal, whether the terminal is a dual-mode terminal supporting the CDMA network and the WiFi network, and if yes, performing step 404; if not, the terminal may terminate, Step 404 and subsequent steps are performed. Step 405: The core network device sends the information about the obtained AP to the BTS.

If the AP is the AP of the cell where the terminal is located, the BSC sends the information of the obtained AP to the BTS.

If it is the AP of the cell in the cell that is obtained by the PDSN, the PDSN sends the acquired AP information to the BSC, and then the BSC forwards it to the BTS.

When there are multiple APs, the core network device can send information of the multiple APs through a list. Send it to the above BTS.

Step 406: The BTS forwards the received AP information to the terminal. In step 405, the core network device may send an AP information to the BTS by sending an instruction to enable the WiFi function. The command may also be used to instruct the terminal to enable the WiFi function. . In step 406, the BTS sends an instruction to turn on the WiFi function to the terminal.

Step 407: The terminal establishes a connection with one of the APs according to the AP information, and accesses the core network device through the AP. After receiving the instruction to enable the WiFi function, the terminal starts the WiFi function of the terminal, and establishes a connection with one of the APs according to the received AP information. If the received AP information includes multiple APs, the terminal may try to establish a connection with each AP in sequence from the first AP. Once the connection with one of the APs is successfully established, the AP does not try to connect with other APs. establish connection. Optionally, when the core network device sends data to the terminal, after step 407, the method further includes:

Step 408: The core network device sends the data of the terminal to the terminal.

As shown in the solid line of FIG. 6 (b), if the load of the BTS is greater than the load of the AP, the core network device selects the AP, and sends data of the terminal to the AP through the AP. If the load of the BTS is equal to the load of the AP, the core network device randomly selects one of the BTS and the AP, and sends the data of the terminal to the randomly selected BTS or AP. The terminal.

In order to allow the core network device to obtain the load of the BTS and the AP in real time, the BTS or the AP can periodically report the load of the BTS or the AP to the core network device. The core network device in the embodiment of the present invention may be a BSC or a PDSN. Through the method provided in Embodiment 4 of the present invention, the terminal itself can obtain the WiFi access point information from the core network device by interacting with the core network device, thereby eliminating the need for the user to perform a complicated operation on the terminal to search.
