Embodiment Construction

[0061] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0062] The method for the ANDSF of the present invention to provide the access network protocol selection function is as follows: Image 6 shown, including:

[0063] Step 601, the ANDSF generates an access network list according to the access network request message sent by the UE;

[0064] Step 602, the UE selects an access network from the access network list according to the access network protocol type supported by itself;

[0065] In step 603, the UE initiates handover to the selected access network.

[0066] Figure 7 Shown is the method flow chart of the first embodiment of the ANDSF of the present invention providing the access network protocol selection function, the process includes:

[0067] 701. The UE accesses the EPS system.

[0068] The UE accesses the EPS system through the current access network...

Abstract

The invention discloses a method for providing an access network protocol selection function by an access network discovery and selection function (ANDSF), comprising: the ANDSF generates an access network list according to an access network request message sent by user equipment (UE); and the UE selects an access network from the access network list according to an access network protocol type supported by self and initiates switching to the selected access network. The invention also provides a system for providing an access network protocol selection function by an ANDSF. The method and the system can solve the problem of service interruption caused by inconsistent access network protocol types supported by the UE and the access network when the UE switches the access network.
