Embodiment 1
[0060] This embodiment provides a method for selecting a core network access management network element, such as Figure 4 shown, including:
[0061] Step 110, the network node obtains the virtualization attribute of the access management network element, and the virtualization attribute is used to indicate that the access management network element is a physical network element or a virtual network element;
[0062] Selecting the core network access management NE may be performed by the radio base station or the initial access management NE (the first access network management NE that receives the UE's NAS message).
[0063] In an example, the network node is a wireless base station, and the wireless base station obtains the virtualization attribute of the access management network element through at least one of the following methods:
[0064] The wireless base station obtains the virtualization attribute of the access management network element through the connection estab...
Embodiment 2
[0110] In this embodiment, the UE requests to access the network, and the wireless base station selects an access management network element for the UE.
[0111] Figure 6 It is the signaling process for the eNodeB to select the MME for the UE when the UE requests to access the 4G network in this embodiment, including:
[0112] 401. The UE initiates an RRC connection request to the eNodeB, which carries a NAS access request;
[0113] 402. The eNodeB selects an MME for the UE according to the acquired virtualization attribute of the MME and the network preference policy;
[0114] 403, the eNodeB sends an initial context request message to the selected MME, carrying a NAS access request;
[0115] 404, the MME sends a location update request to the HSS;
[0116] 405. The HSS returns a location update to the UE, wherein the subscription data of the UE is carried;
[0117] 406. The MME selects an SGW / PGW for the UE, and initiates a session establishment request to the SGW / PGW; ...
Embodiment 3
[0146] In this embodiment, the UE requests to access the network, and the initial MME reselects an MME for the UE.
[0147] Such as Figure 10 As shown, the present embodiment has the following steps:
[0148] 801. The UE initiates an RRC connection request to the eNodeB, which carries a NAS access request;
[0149] 802. The eNodeB selects an initial MME for the UE, that is, Figure 8 MME1 in , sends an initial context request message to MME1, carrying a NAS access request;
[0150] The initial MME is the first MME that receives the NAS access request. The initial MME can be a specific MME. This MME has information about other MMEs, and this MME can execute the redirection process. The initial MME may not be a specific MME, and multiple MMEs are equal, and can all complete the functions of the initial MME.
[0151] 803. MME1 sends an authentication request to the HSS;
[0152] 804. The HSS returns an authentication response to MME1, where the UE type information of the UE...
