Embodiment Construction

[0056] The present invention proposes a method for reselecting a serving MME / UPE by eNodeB according to the load status, route measurement or link status of the connected MME / UPE when UE initiates a Tracking Area (TA) update request. Specifically include:

[0057] When the eNodeB receives the tracking area update request message initiated by the UE, the eNodeB selects an MME / UPE that satisfies the best service quality among the MME / UPEs connected to itself as the target MME / UPE after reselection; and sends a message to the target MME / UPE sends an access request; the target MME / UPE makes an access decision to determine whether the eNodeB is allowed to access; the target MME / UPE interacts with the serving MME / UPE of the UE before reselection to obtain the mobility management context of the UE; the target MME The / UPE executes the location update registration process of the UE, and becomes the serving MME / UPE of the UE after reselection.

[0058] As shown in FIG. 7 , it is a sc...

Abstract

The invention is used in an evolution network. After eNodeB of the evolution network base station receives the request for updating the tracing area from a UE, the method comprises: a) said eNodeB selects a MME / UPE satisfying best QoS from the MME / UPEs connected to it as the destination MME / UPE after reselection; b) said eNodeB sends an access request to said destination MME / UPE; c) said MME / UPE interacts with the serving MME / UPE of said UE before reselection to get the mobility management context of said UE; d) said MME / UPE executes the location update registration process for said UE and becomes the serving MME / UPE of said UE after reselection.

Description

technical field [0001] The present invention relates to an evolved network, in particular to a method for reselecting a user equipment (User Equipment, UE) mobility management entity (Mobility Management Entity, MME) / user plane entity (User Plane Entity, UPE) in the evolved network. Background technique [0002] The Universal Mobile Telecommunications System (UMTS) is a third-generation mobile communication system using the WCDMA air interface technology, and the UMTS system is usually also called a WCDMA communication system. The UMTS system adopts a structure similar to that of the second generation mobile communication system, including a radio access network (Radio Access Network, RAN) and a core network (CoreNetwork, CN). Among them, the wireless access network is used to handle all wireless-related functions, while the CN handles all voice calls and data connections in the UMTS system, and realizes switching and routing functions with external networks. The CN is logi...
