Problems solved by technology

[0034] The disadvantages of the prior art are: 1. It takes a long time to transfer the user. From the time when the SGSN decides to transfer the user to when the user transfers to the new SGSN, it takes at least one cycle time, such as 4 seconds; Releasing the signaling connection twice will lead to excessive network overhead. If there are many users transferred in a short period of time, the load on the device will increase.

Embodiment Construction

[0058] The idea of ​​the present invention is: when the user needs to be transferred, the serving MME / UPE transfers the attach request or tracking area update request from the UE to the target MME / UPE, and the target MME / UPE establishes a signaling connection with the E-RAN, and the target MME / UPE The UPE completes the attach or tracking area update process of the UE.

[0059]The following takes UE performing network attachment as an example to illustrate the user transfer process between MME / UPE in the present invention. Tracking area update is similar to it, the only difference is that UE and MME / UPE exchange tracking area update request and confirmation message, which will not be further described here.

[0060] FIG. 5 is a schematic diagram of the transfer process between MME / UPE when UE performs network attachment in an evolved network according to the present invention. Among them, k MME / UPE form an MME / UPE pool, where MME / UPE 1 is the serving MME / UPE of the UE. MME / U...

Abstract

The present invention discloses a method of transferring users between different core-network equipments, and includes: a serving core network equipment transfers the attachment request from user equipment or the updating request from tracking area to an aim core-network equipment; the aim core-network equipment establishes a signaling connection with the corresponding wireless access network; the aim core-network equipment is in charge of solving the attachment request from user equipment or the updating request from tracking area. By introducing the present invention, user equipments can be transferred to aim core-network equipment through the only process of user equipment attachment or tracking area update. The process is simple, effective and rapid.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for transferring users between different core network devices. Background technique [0002] The Universal Mobile Telecommunications System (UMTS) is a third generation wireless communication network defined by the 3GPP organization. A UMTS network consists of a core network, a radio access network and user equipment. The core network includes a circuit domain and a packet domain. The circuit domain provides services based on circuit switching (such as voice services), while the packet domain provides services based on packet switching (such as Internet access). The wireless access network provides a wireless air interface, and the user equipment is the terminal equipment used by the user. [0003] Referring to FIG. 1 , it is a schematic diagram of a UMTS network structure in the prior art. Since the present invention only involves the packet domain of the core n...
