[0088] The first embodiment: when the MME / UPE is merged, the service MME / UPE migration triggering condition parameter delivery process and specific migration process.

[0089] Referring to Fig. 6, the first embodiment of the present invention includes the following steps:

[0090] In step 101, the S-eNodeB initiates a normal Intra-LTE handover process. The handover process is the same as that of the prior art, and will not be repeated here.

[0091] Step 102, after successfully accessing the target cell, the UE sends a handover completion message to the T-eNodeB to indicate that the handover is complete.

[0092] Step 103, after receiving the handover completion message, the T-eNodeB may select T-MME / UPE or not select T-MME / UPE. The process of selecting T-MME / UPE is as follows: According to the configured MME / UPE list of the primary pool and the MME / UPE list information of the neighboring pool, it is judged that the current serving MME / UPE, that is, the S-MME / UPE, is in the ...

no. 2 example

[0107] The second embodiment: the MME / UPE is separated, a handover completion message is sent to the MME, and the MME / UPE migrates at the same time.

[0108] Referring to Fig. 7, the flow process of the second embodiment is as follows:

[0109] In step 201, the S-eNodeB initiates a normal Intra-LTE handover procedure. The handover process is the same as that of the prior art, and will not be repeated here.

[0110] In step 202, after receiving the handover completion message, the T-eNodeB may select T-MME / UPE or not select T-MME / UPE. The process of selecting the T-MME / UPE is similar to step 102 in the first embodiment, and will not be repeated here.

[0111]T-eNodeB sends a handover completion message to S-MME. If T-MME / UPE is not selected, the message contains the MME / UPE list of the primary pool to which T-eNodeB belongs and the MME / UPE list information of the neighboring pool; If T-MME / UPE is selected, the message contains the selected T-MME / UPE information. The message...

[0137] Embodiment 3: MME / UPE is separated, a handover completion message is sent to the MME, and only the UPE is migrated.

[0138] Referring to Fig. 8, the process of the third embodiment of the present invention is as follows:

[0139] In step 301, the S-eNodeB initiates a normal Intra-LTE handover process. The handover process is the same as that of the prior art, and will not be repeated here.

[0140] In step 302, after receiving the handover completion message, the T-eNodeB may select T- / UPE or not select T-UPE. The process of selecting a T-UPE is as follows: According to the configured UPE list of the primary pool and the UPE list information of the neighboring pool, it is judged that the current serving UPE is in the neighboring pool list, and a UPE is selected from the UPE list of the primary pool as the serving UPE to migrate T-UPE.

[0141] T-eNodeB sends a handover completion message to S-MME. If T-UPE is not selected, the message contains the UPE list of the pr...

Abstract

This invention discloses a migration method for network entity of a packet core network including: A, T-eNodeB informs a UE to a source packet core network entity to finish switching from S-eNodeB to T-eNodeB and carries with a migration parameter in the notification, B, the source packet core network entity triggers migration according to said migration parameter and transmits context of the UE to a target packet core network entity, C, the source entity sends the address information of the target entity to the T-eNodeB and informs it to exchange service packet core network eitity, D, the T-eNodeB asks the target one to provide service, which carries out route update between anchor points with the access system.

Description

technical field [0001] The invention relates to the field of packet core network technology, in particular to a migration method of a packet core network network entity. Background technique [0002] The Universal Mobile Telecommunications System (UMTS) is a third-generation mobile communication system that adopts Wideband Code Division Multiple Access (WCDMA) air interface technology, and the UMTS system is usually called a WCDMA communication system. Referring to Fig. 1, the UMTS system adopts a structure similar to that of the second generation mobile communication system, including user equipment (UE), terrestrial radio access network (UTRAN) and core network (CN). Among them, UTRAN is used to handle all wireless-related functions, while CN is used to handle all voice calls and data connections in the UMTS system, and realize the switching and routing functions with external networks. CN is logically divided into circuit switched domain (CS) and packet switched domain (...
