Embodiment 1

[0030] In the SAE system architecture, the first network element on the network side is the MME, and the second network element on the network side is the ServingGW and the PDN GW. The MME sends a delete bearer request message to the Serving GW. The delete bearer request message carries an identifier, indicating that the Serving GW and PDN GW bearer deletion processing type: delete a single bearer / delete all bearers on an IP address / delete all bearers of a user.

[0031] Specifically, the delete type (Delete Type) identifier is added to the delete bearer request message sent by the MME to the Serving GW. The value of this type is 0, indicating that a single bearer is deleted; All bearers; the value of this type identifier is 2, indicating that all bearers on a user are deleted.

[0032] Or use the teardown indicator (Teardown Ind) in the delete bearer request message. If the indicator is 0, it means deleting a single bearer. When the indicator is 1, it means deleting all beare...

Embodiment 2

[0052] In the GERAN / UTRAN system, the first network element on the network side is the SGSN, and the second network element on the network side is the Serving GW and the PDN GW. The SGSN sends a Delete PDP Context Request (Delete PDP Context Request) message to the Serving GW. The request (Delete PDP Context Request) message carries an identifier, indicating the processing type of bearer deletion by the Serving GW and the PDN GW: delete a single bearer / delete all bearers on an IP address / delete all bearers of a user.

[0053] Specifically, the SGSN sends a Delete PDP Context Request (Delete PDP Context Request) message to the Serving GW to notify the Serving GW to delete the bearer, and adds the delete type (Delete PDP Context Request) message to the Serving GW. Type) identification or teardown indicator (Teardown Ind) or bearer identification information or user plane tunnel endpoint identifier information or control plane tunnel endpoint identifier information, the value of t...

Embodiment 3

[0072] In the SAE system architecture, the first network element on the network side is the MME, and the second network element on the network side is the Serving GW and the PDN GW. The MME sends a delete user bearer request message (Delete UE Bearer Request) to the Serving GW or does not carry any information elements. The delete bearer request message indicates that the Serving GW and the PDN GW delete all bearers of the user.

[0073] The system described in Embodiment 3 above includes UE, E-UTRAN, the first network element MME on the network side, gateway devices Serving GW and PDN GW, wherein:

[0074] The gateway device includes an analysis module and a bearer deletion module. The analysis module is used to analyze the received delete user bearer request message or the delete bearer request message without any cell, and instruct the bearer deletion module to delete all bearers of the user. The bearer deletion module is based on The instruction of the parsing module delet...

Abstract

The invention provides a method and a system for deleting loads. The method includes that a Serving GW (gateway) receives deleting loading request information transmitted by a mobility management entity (MME) to indicate all loads of users deleted by the Serving GW, wherein the deleting loading request information carries identification of loading types for requesting deleting, and the identifications are used for indicating all loads of the users deleted by the Serving GW. By the aid of the method and the system for deleting loads in the embodiment, when in need of deleting all the loads of the users, the MME can transmit a deleting request once to the Serving gateway so that for users with multiple IP (internet protocol) users, transmitting messages multiple times is omitted, and the messages of interfaces between the MME and the Serving GW are reduced.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, in particular to the technology related to bearer in mobile communication. Background technique [0002] A system architecture diagram of a new evolved network based on 3GPP figure 1 As shown, it includes: Evolved UMTS (Universal Mobile Telecommunications System Universal Mobile Communications System) Terrestrial Radio Access Network (E-UTRAN, Evolved UMTS Terrestrial Radio Access Network), which is used to realize all functions related to the evolved network wireless; mobility The management entity (MME, Mobility Management Entity) is responsible for the mobility management of the control plane, including the management of user context and mobility status, and the allocation of user temporary identities, etc.; the serving gateway entity (Serving GW, Serving Gateway) is the 3GPP access system The user plane anchor point, terminates the interface of E-TURAN; the packet data network g...
