Embodiment 1

[0051] Such as image 3 As shown, the processing method of the bearer suspension includes:

[0052] S301. Receive a notification to suspend the bearer initiated by a network element of the access network;

[0053] S302. Notify the S-GW to suspend the unilateral bearer of the SGSN or the MME, or suspend the bearer of both the SGSN and the MME;

[0054] S303. The suspension state of synchronizing the SGSN and the MME is unilaterally suspended by the SGSN or the MME, or bilaterally suspended by the SGSN and the MME.

[0055] Wherein, the order of the steps S302 and S303 can be interchanged, or the synchronization of the suspended state can be performed first, and then the notification of the bearer suspension can be issued.

[0056] In the bearer suspension processing method provided by the embodiment of the present invention, the MME / SGSN notifies the S-GW of suspending the bearer, and at the same time notifies the SGSN / MME that the S-GW has suspended the bearer, or the S-GW i...

Embodiment 2

[0058] Such as Figure 4 As shown, the processing method for bearer recovery includes:

[0059] S401. Receive a bearer restoration notification initiated by a user equipment or an access network element;

[0060] S402. Notify the S-GW to restore the unilateral bearer of the SGSN or the MME, or restore the bilateral bearer of the SGSN and the MME;

[0061] S403. The recovery status of the synchronous SGSN and MME is unilateral recovery of the SGSN or MME, or bilateral recovery of the SGSN and MME.

[0062] Wherein, the order of the steps S402 and S403 can be interchanged, and the synchronization of the recovery status can also be performed first, and then the notification of the bearer recovery can be issued.

[0063] In the method for processing the bearer recovery provided by the embodiment of the present invention, the MME / SGSN notifies the S-GW to restore the bearer while notifying the SGSN / MME that the S-GW has recovered the bearer, or the S-GW restores both sides at the...

Embodiment 3

[0065] The scenario provided in this embodiment is that after receiving the suspension message, the S-GW suspends both bearers of the MME and the SGSN on the premise of activating the ISR. While notifying the S-GW to suspend the bearers on both sides, the MME / SGSN also needs to notify the SGSN / MME through the interface S3 between the SGSN and the MME that the S-GW has suspended the bearers on both sides, and the SGSN / MME records two The side bearer has been suspended; or the S-GW notifies the other side that the S-GW has suspended both sides of the bearer while suspending both sides of the bearer.

[0066] During recovery, after receiving the recovery request message, the S-GW recovers the bearers of both the MME and the SGSN. While notifying the S-GW to restore the bearers on both sides, the MME / SGSN also needs to notify the SGSN / MME through the interface S3 between the SGSN and MME that the S-GW has restored the bearers on both sides, and the SGSN / MME records that the bearer...

Abstract

The invention discloses method and device for processing the hanging up and the recovery of load bearing. The method for processing the hanging up of the load bearing comprises the following steps of: receiving a notice of hanging up the load bearing, wherein the notice is sponsored by a network element of an access network; notifying S-GW to hang up the load bearing of the single side of SGSN (Service GPRS Supporting Node) or MME (Multi Media Extension) or the load bearing of both sides of the SGSN and the MME; and synchronizing the hanging-up states of the SGSN and the MME to the hanging-upstate of the single side of the SGSN or the MME or the hanging-up states of both sides of the SGSN and the MME. The method for processing the recovery of the load bearing comprises the following steps of: receiving a notice of recovering the load bearing, wherein the notice is sponsored by user equipment or the network element of the access network; notifying the S-G to recover the load bearing of the single side of the SGSN or the MME or the load bearing of both sides of the SGSN and the MME; and synchronizing the recovering states of the SGSN and the MME to the recovering state of the single side of the SGSN or the MME or the recovering states of both sides of the SGSN and the MME. The invention is suitable for unifying the hanging-up state and the recovering state of the load bearing.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a processing method and device for bearer suspension and recovery. Background technique [0002] GPRS / UMTS (General Packet Radio Service / Universal MobileTelecommunications System, General Packet Radio Service / Universal Mobile Telecommunications System) is a mobile communication network defined by 3GPP organization, including radio access network (Radio Access Network, RAN) and core network ( Core Network, CN) in two parts. The CN is logically divided into a circuit switched domain (Circuit Switched Domain, CS) and a packet switched domain (Packet Switched Domain, PS). [0003] Such as figure 1 As shown, SGSN (Serving GPRS Support Node, serving GPRS support node) is a PS domain control plane entity. When the UE accesses the SGSN through the A interface of the BSC to complete the PS service, it is a GPRS service; when the UE accesses the SGSN through the Iu interfa...
