Problems solved by technology

[0018] After the UE receives the MME instruction to start the mobility management timer during the TAU process and starts it, how should the UE handle the situation that the length of the mobility management timer is longer than the length of the periodic tracking area update timer? no clear solution

Embodiment 1

[0051] In this embodiment, the mobility management procedure of the UE is an attach procedure ATTACH, and the mobility management accept message is an attach accept message.

[0052] Preferably, the network side sends a mobility management acceptance message to the UE according to whether the congestion control mechanism is enabled for different APNs, including: the first network entity determines the APN that the UE requests to connect during the attach process; Whether the APN enables the congestion control mechanism and sends an attach acceptance message to the UE.

[0053] When applied to the EPS system, the above-mentioned first network entity is the MME.

[0054] In this embodiment, the MME determines the APN that the UE requests to connect during the attach process, specifically including: determining that the APN is the APN that the UE requests to connect when the message sent by the UE during the attach process carries the APN; If the message sent during the process ...

Embodiment 2

[0073] The mobility management acceptance message described in this embodiment is a location update acceptance message. The location update process may involve scenarios where the SGW changes or does not change. In this embodiment, the SGW does not change, and the network entity that communicates with the UE on the network side When (MME / SGSN) is changed or not changed, a specific implementation will be given.

[0074] For the scenario where the network entity on the network side has not changed, the network side sends a mobility management acceptance message to the UE according to whether the APN enables the congestion control mechanism, including: the first network entity determines that the serving gateway SGW is in the process of updating the location of the UE When there is no change, determine the APN that has established a connection with the UE before the location update; when the first network entity determines that one of the APNs that has established a connection wit...

Embodiment 3

[0108] When the mobility management acceptance message described in the embodiment of the present invention is a location update acceptance message, the location update process may involve a scene where the SGW changes or does not change. In this embodiment, the SGW changes, and the communication between the network side and the UE When the network entity (MME / SGSN) changes or does not change, a specific implementation is given.

[0109] In this embodiment, the network side sends a mobility management acceptance message to the UE according to whether the APN has enabled the congestion control mechanism, including: when the network side determines that the serving gateway SGW changes during the location update process of the UE, it Whether there is an APN among the APNs that have established a connection to enable the congestion control mechanism, and send a location update acceptance message to the UE.

[0110] When the SGW changes, the network entity that receives the cell up...

Abstract

The present invention relates to wireless communication technology, and discloses a method for rejecting a mobility management process and a network side device. The method includes: the network side starts a congestion control mechanism according to different access point names (APNs) during the UE mobility management process , sending a mobility management accept message to the UE; the network side carries a mobility management backoff timer in the mobility management accept message. The present invention can further save resources of UE and network side, and achieve better network congestion control purpose.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for rejecting a mobility management process and a network side device. Background technique [0002] APN (Access Point Name, Access Point Name) is an important parameter used when a network entity selects a gateway node of a PDN (Packet Date Network, packet data network) in a mobile communication network. Different APNs correspond to different gateway nodes. A connection between the gateway nodes corresponding to an APN is used to establish a connection to the APN. [0003] For different application scenarios, the above-mentioned network entity is MME (Mobility Management Entity, mobility management entity) or SGSN (Serving GPRS Support Node, serving GPRS service node), and the gateway node is PGW (Packet Data Network Gateway, packet data gateway) or GGSN (Gateway GPRS Support Node, gateway GPRS supports node). [0004] For EPS (Evolved Packet Sy...
