Embodiment Construction
[0031] An embodiment of the present invention provides a switching method for accessing a network. In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0032] Please refer to figure 1 , is a signaling flowchart of the first embodiment of the access network handover method of the present invention. In this embodiment, a mobile terminal (UE, User Equipment) switches from a non-3GPP access network to a 3GPP access network. The access network switching process includes:
[0033] Step 101: The mobile terminal detects the signal of the non-3GPP access network, and connects to the non-3GPP access network;
[0034] Step 102: The non-3GPP access gateway discovers that the mobile terminal needs to access the SAE core network, and sends a mobile terminal access authentication request to the HSS / AAA, and the non-3GPP access network obtains the...

The invention provides an access network switch method, a anchor point management equipment and a mobile access equipment. The method comprises: when a mobile terminal moves from a first network which using a first moving management protocol to a second network which using a second moving management protocol, the access gateway or MME acquires the anchor point address, which includes an anchor point address corresponding to the second moving management protocol indicating the anchor equipment used by the mobile terminal in the first network, corresponding to the moving management protocol from the anchor point management equipment, using the second moving management protocol according to the anchor point address corresponding to the second moving management protocol, establishing the connection of the access gateway or MME and the anchor point equipment indicated by the anchor point address corresponding to the second moving management protocol. Through the technical scheme in the invention, switching between the accessing networks adopting different moving management protocols can keep the continuity of data service.
Description
technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an access network switching method, an anchor point management device, and a mobile access device. Background technique [0002] At present, a typical wireless communication network defined by the 3rd Generation Partnership Project (3GPP, The 3rd Generation Partnership Project) standard organization is generally composed of a 3GPP radio access network and a 3GPP wireless core network. [0003] The 3GPP System Architecture Evolution (SAE, 3GPP System Architecture Evolution) network supports 3GPP access technology, non-3GPP (non-3GPP) access technology and mobility between heterogeneous access networks. In the SAE network, a Packet Data Network Gateway (PDN GW, Packet Data Network Gateway) assigns an IP address to a mobile terminal. In order to support the mobility of mobile terminals between heterogeneous wireless access networks, the SAE network uses the PDN...
