Embodiment Construction

[0081] The idea of ​​the present invention is: when the serving MME / UPE requests the HSS to register, designate a standby MME / UPE for the MS; after the serving MME / UPE fails, the HSS obtains the notification of the failure of the MME / UPE and requests the standby MME / UPE to page The MS also instructs the MS to re-perform the network attach. After the MS attaches to the network again, all communication activities of the user can proceed normally.

[0082] When the mobile terminal performs network attachment, or initiates a tracking area update due to a tracking area change, the serving MME / UPE of the mobile terminal designates a standby MME / UPE for the mobile terminal. Taking the flow of the mobile terminal performing network attachment for the first time as an example, the process of designating the standby MME / UPE for the mobile terminal by the serving MME / UPE is described below. Since in the network attach process, the subsequent process after the MME / UPE registers with the ...

Abstract

The method comprises: when the serving core network equipment attached by a mobile terminal fails, the standby core network equipment previously appointed by the serving core network pagings the mobile terminal to indicate the mobile to re-execute a network attachment. By the invention, when the serving core network equipment fails, the mobile terminal attached to said serving core network equipment can be rapidly attached to the another core-network equipment.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for a mobile terminal to reattach to a network. 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] see figure 1 , 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 network, the circuit doma...
