Problems solved by technology

[0018] Therefore, if the UE enables ISR (Idle mode Signaling Reduction, saving signaling or restriction signaling in idle mode) and camps on the SGSN side, when the MME side performs the Handover process to achieve MME load balancing, the MME side cannot page to the UE to turn it into a connected state, so the new GUTI allocated by the New MME cannot be notified to the UE, and the New MME cannot complete the registration to the HSS and other related problems

Embodiment 1

[0054] Embodiment 1: MME load balancing adopts the Handover processing method. UE enables ISR and resides on the SGSN side. The SGSN obtains the GUTI Reallocation Command message sent by the MME side, and the SGSN pages the UE to assign the new GUTI allocated by the New MME. Notify the UE by forwarding the GUTI Reallocation Command or RAU Accept message, and instruct the UE to return to the MME next time to actively initiate the TAU process to complete the registration from the New MME to the HSS.

Embodiment 2

[0055] Embodiment 2: MME load balancing adopts the Handover processing method, UE enables ISR and resides on the SGSN side, the SGSN obtains the GUTI Reallocation Command message sent by the MME side, the SGSN pages the UE, and forwards the new GUTI allocated by the New MME through the GUTI Reallocation The Command or RAU Accept message is notified to the UE, and the SGSN replies that the New MME has notified the UE of the New GUTI, and the New MME actively completes the registration with the HSS.

Embodiment 3

[0056] Embodiment 3: MME load balancing uses the GUTI Reallocation Command message to notify the UE and trigger the UE to initiate a TAU process. The UE enables ISR and resides on the SGSN side, and the SGSN obtains the MME side to send a specific message (such as a trigger message) to trigger the SGSN paging Idle state UE. The MME forwards the GUTI Reallocation Command message or the TAU Request message to the SGSN, and the SGSN notifies the UE of the new GUTI allocated by the New MME by forwarding the GUTI Reallocation Command or RAU Accept message or forwarding the TAU Accept message, and instructs the UE to return to the MME next time to initiate the TAU process to complete Registration of New MME to HSS.

Abstract

The invention discloses a method and equipment for realizing terminal migration in an ISR scene, and belongs to the communication field. The method includes: the terminal enables the ISR for saving signaling in the idle mode of the old-side network element on the first network side and the second network element on the second network side, and resides on the second network side, and the method includes: second The network element obtains the globally unique temporary identifier newly allocated by the new side network element on the first network side; paging the terminal, sends the globally unique temporary identifier to the paged terminal; replies with a completion message, and completes the signing of the new side network element with the home location Registration of User Server HSS. The equipment includes: an acquisition module, a paging module, a sending module and a reply module. No matter when the UE activates ISR to camp on the SGSN side, or when the UE activates ISR to camp on the MME side but the location area remains unchanged, the present invention ensures that the UE obtains the newly allocated GUTI identifier on the MME side, and ensures that the new side MME completes the registration of the HSS. Realize the migration of the ISR-enabled terminal, complete the MME load balancing processing, and similarly, also realize the SGSN load balancing processing.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for realizing terminal migration in an ISR scene. Background technique [0002] With the development of wireless communication technology, see figure 1 , provides a schematic diagram of a wireless evolution network architecture, wherein the core network of the current wireless evolution network mainly includes MME (Mobility Management Entity, mobile management entity), SGW (Serving Gateway, serving gateway), PGW (PDN Gateway, Packet DataNetwork Gateway , packet data network gateway) three logical functional bodies, among which, MME is the mobile management entity responsible for NAS (Non-Access-Stratum, non-access stratum) signaling and NAS signaling encryption, roaming, tracking and other functions, and assigns users temporary Identity identification, security functions, etc., the SGW is responsible for the local mobility anchor point and the mobility ancho...
