Embodiment Construction

[0038] The basic idea of ​​the present invention is to use an indication parameter in the GTPv2 protocol, and perform different deletion operations according to different values ​​of the parameter, including: deleting all GTP-U addresses and TEIDs of the UE, deleting all GTP addresses and TEIDs of the UE , and delete all bearers of the UE, etc. This parameter can be used in many processes, as long as there is a demand for deletion, the embodiment of the present invention is not limited to a certain process; Carrying a large number of parameters indicating to be deleted improves the efficiency of bearer management.

[0039] In order to enable those skilled in the art to better understand the present invention, the method of the present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0040] Embodiment 1 of the present invention provides a method for deleting a bearer, such as figure 2As shown, the method includes:

Abstract

The invention provides a method for deleting a GTP tunnel, which comprises the steps of: receiving a deletion indication parameter; searching a preset deletion list according to a value of the received deletion indication parameter; and executing the operation of deleting a general packet radio service (GPRS) tunnel protocol (GTP) according to a search result. The invention also provides a device and a system for deleting the GTP tunnel. by defining the deletion indication parameter in a GTPv2 protocol and executing the corresponding operation of deleting the GTP tunnel according to the value of the deletion indication parameter, the method and the system avoid containing a large amount of bearing or GTP information in a request message, also avoid sending the request message for multiple times, simplify the operation flow in the system, and improve the efficiency of bearing management.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method, device and system for deleting a GTP tunnel. Background technique [0002] In order to support the new functions and features of the EPS (Evolved Packet System, Evolved Packet System) system, the traditional GTPv1 (General Packet Radio Service Tunneling Protocol, General Packet Radio Service Tunneling Protocol) protocol needs to be upgraded to GTPv2 to implement the bearer tunnel in the EPS system management and some mobility management functions. Among them, the tunnel management message of GTPv2 is used to establish, update and delete bearer tunnels between different functional nodes of EPC (Evolved Packet Core network). These tunnel management operations are currently specified in 3GPP TS23.401. It is respectively performed through GTPv2 Create Bearer Request and Response, Update Bearer Request and Response, and Delete Bearer Request and Response messag...
