Embodiment Construction

[0090] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0091] The present invention provides a paging optimization method, which mainly includes: MME receives downlink data arrival notification message from SGW, and obtains the identification information of eNodeB connected to UE according to the downlink data arrival notification message; MME paging the eNodeB connected to UE , or initiate establishment of a downlink user plane data transmission tunnel between the eNodeB connected to the UE and the SGW.

[0092] Wherein, the MME obtains the identification information of the eNodeB connected to the UE according to the downlink data arrival notification message, including:

[0093] Obtain the identification information of the eNodeB connected to the UE directly from the downlink data arrival notification message; or, the location information of the UE is carried in the do...

Abstract

The present invention discloses a paging optimization method, comprising: a mobility management entity MME receives a downlink data arrival notification message from a serving gateway SGW, and obtains identification information of a base station eNodeB connected to a user equipment UE according to the downlink data arrival notification message ; the MME paging the eNodeB connected to the UE, or initiates establishment of a downlink user plane data transmission tunnel between the eNodeB connected to the UE and the SGW. Through the present invention, the information transmission overhead in the process of establishing the fast path can be reduced, and the resource consumption when the UE is paging can be reduced.

Description

technical field [0001] The invention relates to fast path establishment technology in the communication field, in particular to a paging optimization method, device, system and fast path release method and device. Background technique [0002] With the sudden emergence of WIMAX (World Interoperability for MicrowaveAccess), the third-generation mobile communication system must improve its network performance and reduce network construction and operation in order to maintain its strong competitiveness in the field of mobile communication. the cost of. Therefore, the standardization working group of the 3rd Generation Partnership Project (3GPP, 3rdGeneration Partnership Project) is currently working on the study of the Packet Switching Core Network (PSCore, Packet Switch Core) and the Global System for Mobile Communications Radio Access Network (UTRAN, Universal MobileTelecommunication The evolution of System Radio Access Network), this research topic is called System Architec...
