Embodiment 1

[0069] Such as image 3 As shown, Embodiment 1 of the present invention provides a bearer release method, which can be applied to a mobility management entity MME, and the bearer release includes:

[0070] Step 31: When receiving the handover request sent by the source base station, judge whether to receive the bearer release request sent by the user plane functional entity gateway SAE-GW and carrying the cause value of the release initiation before receiving the handover request;

[0071] Step 32: If yes, send a notification message for indicating handover failure to the source base station, and a release instruction for the S1 bearer between the base station and the core network.

[0072] The bearer release method provided in Embodiment 1 of the present invention determines whether, before receiving the handover request sent by the source base station, whether the bearer release request sent by the user plane functional entity gateway SAE-GW and carrying the cause value for ...

Embodiment 2

[0076] Such as Figure 4 As shown, Embodiment 2 of the present invention provides a bearer release method, which can be applied to the user plane functional entity gateway SAE-GW, and the bearer release method includes:

[0077] Step 41: Receive a random access response RAR message that is sent by the charging policy control unit PCRF and carries a cause value for initiating release;

[0078] Step 42: According to the RAR message, obtain the bearer release request carrying the cause value of initiating release, and send it to the corresponding mobility management entity.

[0079] The bearer release method provided in Embodiment 2 of the present invention sends a bearer release request carrying a cause value for initiating release to the corresponding mobility management entity, so that the corresponding mobility management entity can, when receiving the handover request sent by the source base station, Sending a notification message indicating handover failure to the source b...

Embodiment 3

[0107] Such as Figure 7 As shown, Embodiment 3 of the present invention provides a bearer release device, which can be applied to a mobility management entity MME, and the bearer release device includes:

[0108] The judging module 71 is configured to, when receiving the handover request sent by the source base station, judge whether to receive the bearer release request sent by the user plane functional entity gateway SAE-GW and carrying the cause value of the release initiation before receiving the handover request;

[0109] The first sending module 72 is configured to, before receiving the handover request, when receiving a bearer release request sent by the user plane function entity gateway SAE-GW and carrying a cause value for initiating a release, send a handover instruction to the source base station A failure notification message, and a release instruction for the S1 bearer between the base station and the core network.

[0110] The bearer release device provided in...

Abstract

The invention provides a bearer release method and device, a mobility management entity (MME) and a serving gateway-packet data network gateway (SAE-GAW). The comprises the bearer release method stepsthat when a handover request sent by a source base station is received, whether a bearer release request which is sent by the SAE-GAW and carries a release cause value is received or not is judged before the handover request is received; and if the bearer release request is received, a notification message for indicating handover failure and a release command of S1 bearer between a base station and a core network to the source base station. According to the scheme, the condition that after the release command is received, if the handover request is received, the terminal is meaninglessly andrepeatedly required to carry out handover can be avoided, signal cost is reduced, and the problem that in the prior art, additional signal cost and meaningless handover exist when the handover conflicts with upper layer SIP release is solved well.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a bearer release method and device, a mobility management entity MME and a user plane functional entity gateway SAE-GW. Background technique [0002] The switching process of the existing voice service VoLTE eSRVCC (Enhanced Single Radio Voice Call Continuity, enhanced single radio voice call continuity) is shown in 1, including: [0003] Step 11: A VoLTE session has been established between terminal A and terminal B. Terminal A is an SRVCC (Single RadioVoice Call Continuity) terminal, and the call signaling is anchored on ATCF, and the media plane is anchored on ATGW Above; ATCF (Access Transfer Control Functionality, access transfer control function) and ATGW (Access Transfer Gateway, access transfer gateway), respectively as the anchor point of VoIP call in the control plane and user plane; [0004] Step 12: Terminal A measures neighboring cells according to eN...
