Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] The ANDSF network device ("ANDSF server") and the ANDSF client work together to realize access network discovery and selection functions. The ANDSF client device is installed in the user equipment and communicates with the ANDSF server through the S14 interface. The invention expands the S14 interface, and transmits the WLAN access reference information in it for the ANDSF client to select and access the wireless local area network.

[0021] According to one embodiment of the present invention, figure 1 It shows a process in which an ANDSF network device assists a user equipment in accessing a wireless local area network.

[0022] In step S1, when the user equipment is within the coverage of the wireless local area network, the ANDSF network device acquires access reference information of the wireless local area network. Here, the access reference in...

Abstract

The invention aims to provide a method for accessing a wireless local area network for user equipment and a device thereof. When user equipment is within a coverage area of a wireless local area network, ANDSF network equipment acquires access reference information of the wireless local area network; and the access reference information is provided to the user equipment so as to determine whether to access the wireless local area network. In comparison with the prior art, free WLAN can be accessed by ANDSF clients according to the scheme provided by the invention. However, when a user enters a coverage area of charging WLAN, a window pops up on a mobile phone screen of the user to prompt that the WLAN charges, and it would be better that the user determines whether to access the WLAN.

Description

technical field [0001] The present invention relates to the field of mobile communication technologies, in particular to a technology for accessing a wireless local area network (WLAN, wireless local access network) for user equipment. Background technique [0002] The access network discovery and selection function ANDSF (Access Network Discovery and Selection Function) is a network element defined by 3GPP, which transfers the strategy formulated by the operator to the user equipment to select the 3GPP network and WLAN. If used properly, telecom operators can intelligently offload data from the 3GPP network to the WLAN. [0003] The ANDSF client will decide whether to access the WLAN based on the ISMP policy received from the ANDSF server via the S14 interface. However, the current S14 protocol does not include the relevant information of the WLAN, and the arbitration access of the ANDSF client to the WLAN is not suitable for the user. For example, some WLANs are charged ...
