Embodiment 1

[0080] see Figure 6 , is a schematic flow chart of Embodiment 1 of the present invention, and the specific steps include:

[0081] 1. The source serving MME / UPE sends a paging request message to the eRAN, carrying Re-Attach indication information;

[0082] The Re-Attach indication is an indication bit that needs to be added in the Paging message to instruct the user terminal to reattach.

[0083] 2. The eRAN pages the specified user terminal through the Paging message, carrying the Re-Attach indication information;

[0084] 3. The user terminal being paged sends a Paging Response message to the source service MME / UPE;

[0085] 4. The user terminal sends an AttachRequest message to the target service MME / UPE according to the Re-Attach indication information;

[0086] 5. The remaining steps of the reattachment process are the same Figure 4 shown.

[0087] Embodiment 2: On the basis of Embodiment 1, the Attach Request message and the Paging Response message are combined to...

Embodiment 2

[0088] see Figure 7 , is a schematic flow chart of Embodiment 2 of the present invention, and the specific steps include:

[0089] 1. The source serving ME / UPE sends a paging request message to the eRAN, carrying Re-Attach indication information;

[0090] 2. The eRAN pages the specified user terminal through the Paging message, carrying the Re-Attach indication information;

[0091]3. The paged user terminal sends an Attach Request message to the target serving MME / UPE according to the Re-Attach indication information, and carries the Paging Response indication information at the same time;

[0092] The Paging Response indication is an indication bit that needs to be added in the Attach Request message as a response to the Paging message, and is forwarded by the target service MME / UPE to the source service MME / UPE.

[0093] 4. The target service MME / UPE sends a Paging Response message to the source service MME / UPE;

[0094] 5. The remaining steps of the reattachment proces...

Embodiment 3

[0097] see Figure 8 , which is one of the schematic flow diagrams of Embodiment 3 of the present invention. The flow process is based on Embodiment 2. The specific steps include:

[0098] 1. The source service MME / UPE acquires an identifier of the target service MME / UPE;

[0099] The identifier may be any identifier that can uniquely represent the MME / UPE, such as: Network Resource Identifier (Network Resource Identifier, NRI), MME / UPE number, and the like. The mechanism for obtaining the MME / UPE identifier of the target service is not limited, for example, the one with a lighter load can be selected according to the load condition.

[0100] 2. The source serving MME / UPE of the user terminal sends a paging request message to the eRAN, carrying Re-Attach indication information, and carrying the identity of the target serving MME / UPE;

[0101] 3. The eRAN pages the specified user terminal through the Paging message, and at the same time carries the Re-Attach indication inform...

Abstract

The invention discloses a method for adhering the network newly, which is used in anew adherence initiated by spare user terminal in evolution network, and it includes: the service core network of spare user terminal seeks the spare user terminal via accessing network, and takes the indicating information of anew adherence; the sought user terminal can initiate the requirement for anew adherence according to the indicating information, and adhere on the target service core network. Using the invention, it can reduce the exchange of signaling in anew adherence, and predigest the anew adherence, and reduce the delay of network.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for reattaching to a network initiated by a network for a user terminal in an idle state. Background technique [0002] Universal Mobile Telecommunications System (UMTS) is a third-generation mobile communication system that adopts Wideband Code Division Multiple Access (WCDMA) air interface technology, and UMTS system is usually called 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 (Core Network, 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. CN is logically divided into a circuit switched domain (Cir...
