Access network selection method, user equipment, system and network selection strategy unit

Abstract

The invention discloses an access network selection method, user equipment, a system and a network selection strategy unit. The method includes that the network selection strategy unit receives network selection strategy requests with access network information and sent by the user equipment, the network selection strategy unit obtains access network state information and user configuration information according to the network selection strategy requests, and the network selection strategy unit formulates network selection strategy information according to the access network state information and the user configuration information and sends the network selection strategy information to the user equipment. According to the access network selection method, the user equipment, the system and the network selection strategy unit, the network selection strategy unit can fully obtain the access network information of the position of user experience (UE), the UE detects an MAC address of a wireless local area network (WLAN) access point (AP) and reports to the network selection strategy unit, the UE lists the frequently accessed service set identifiers (SSID) and reports to a user information database unit in a certain time cycle, and the network selection strategy unit selects the best WLAN AP for the user according to the access network information provided by the UE.

Description

technical field [0001] The present invention relates to cellular network and wireless access network technology in the field of communication, in particular to an access network selection method, user equipment, system and network selection policy unit. Background technique [0002] With the deployment of a large number of WLAN hotspots, the same area may be covered by multiple WLAN access points and cellular base stations. It is becoming more and more important to choose a reasonable network for users according to their needs and network usage. At present, the use of the existing network and the existing network selection technical solutions have the following defects: [0003] 1) UE (User Equipment, user equipment) scans the AP (Access Point, access point) information of WLAN (Wireless Local Area Networks, wireless local area network), and is selected by the user according to the available SSID (Service Set Identifier, service set identifier) WLAN access requires users to...
