Method for finding radio local area network in mobile network

Abstract

The invention provides a method for finding a radio local area network in a mobile network, which comprises the following steps of: pre-storing information whether the radio local area network exists in the coverage area of each cell controlled by a radio network controller in the radio network controller, wherein the radio network controller carries the information whether the radio local area network exists in the coverage area of each cell in a system message of the corresponding cell; issuing the information whether the radio local area network exists in the coverage area of the cell wherein UE (User Equipment) locates to the UE through the system message or downlink signaling; activating the radio local area network function after the UE determines that the radio local area network exists in the coverage area of the cell where the UE locates, if the radio local area network function is otherwise activated at present through an instruction of the mobile network, deactivating the radio local area network function. Therefore, the purposes of saving end power and timely finding the radio local area network for switching are realized.

Description

technical field [0001] The invention relates to the fusion technology of a mobile network and a wireless local area network, in particular to a method for discovering a wireless local area network under a mobile network. Background technique [0002] In today's mainstream operators in the world, they all adopt 3G / 2G+WLAN as the main mode of full-service operators. In this way, on the basis of 3G / 2G providing better quality mobile phones, WLAN can be used as a supplementary technology for data domain services to increase the rate of data domain services. At present, there are 3G and WLAN shallow coupling and deep coupling solutions to realize the combination of 3G network and WLAN services. [0003] The representative method of shallow coupling is 3GPP, which stipulates the method of WLAN and 3G integration. In order to achieve the purpose of accessing mobile network value-added services from WLAN access, it is necessary to add a service gateway between the IP network and th...

Problems solved by technology

[0005] Due to the limitations of the network layout and coverage of the wireless LAN, the existing mobile network infrastructure of the mobile operator, the wireless LAN will not cover the entire network, and for the terminal, if the wireless LAN setting is turned on, it will continue to be in the search status, when there is no wireless LAN for camping, the power consumption of the terminal will be a big problem, and if the wireless LAN setting is turned off, the mobile network users will not be able to find the wireless LAN under the coverage of the wireless LAN, so they will not be able to Get high-speed bandwidth services
