Embodiment 1

[0081] The user equipment sends a handover request to the handover server in the WiMAX access network to obtain the target node AP; if the user equipment is a WiMAX and WiFi dual-mode user equipment with single reception and single transmission, the handover request sent to the handover server carries its own Location information, so that the switching server queries the server that saves the AP location information, so as to obtain the target AP; if the user equipment is a WiMAX and WiFi dual-mode user equipment with dual reception and single transmission, the target AP is obtained by listening. For specific procedures, see Embodiment 1;

[0082] Step 202, establishing a tunnel with the switching server to transmit the data frame of the wireless local area network WLAN, so that the switching server simulates the AP of the WLAN to complete the access authentication of the WLAN access network;

Abstract

The invention discloses a method, equipment and a system for switching user equipment between access networks, and relates to the technical field of communication, in particular to the technology of wireless communication. The method comprises the following steps of: sending a switching request to a switching server in a WiMAX access network, acquiring a target access point (AP), establishing a tunnel with the switching server to transmit a data frame of a wireless local area network (WLAN), simulating an AP of the WLAN by the switching server to finish access authentication of a WLAN access network, and switching the WiMAX access network to the WLAN access network according to the target AP. The invention also provides the corresponding equipment and the corresponding system. The method, the equipment and the system can solve the problem of shortening the switching time when the user equipment is switched to the WLAN access network from the WiMAX access network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to wireless communication technology. Background technique [0002] WiFi is an important WLAN (Wireless Local Area Network, wireless local area network) technology, and it is also used for wireless broadband access. At present, there are a large number of WiFi hotspots in operation around the world, providing free or Paid wireless Internet service. WiMAX (Worldwide Interoperability for Microwave Access) is a wireless broadband access technology and one of the third-generation wireless communication technology international standards. Many operators around the world use WiMAX technology to build wireless broadband access networks . Both WiFi and WiMAX are important wireless broadband access technologies, but each has its own advantages and disadvantages. WiFi network deployment is fast, low in cost, higher in bandwidth, and does not require authorization to use spec...
