Description

一种初始上下文建立失败后业务恢复方法、终端及系统 One kind of initial context service recovery method, system and terminal after establishment fails

技术领域 FIELD

[0001] 本发明涉及无线通信领域,尤其涉及一种初始上下文建立失败后业务恢复方法、 终端及系统。 [0001] The present invention relates to wireless communications, and in particular, to a failure of an initial context setup service restoration method, a terminal and a system.

背景技术 Background technique

[0002] 随着无线通信技术的发展,人们对数据业务的需求日益提高。 [0002] With the development of wireless communication technology, the demand for data services is increasing. 长期演进(Long Term Resolved,LTE)技术因为其永久在线,业务数据速率,系统容量大等特点而得到大力发展。 Long Term Evolution (Long Term Resolved, LTE) technology because of its permanent online traffic data rate, system capacity and other characteristics have been actively developed. 在现有技术中,用户设备(User Equipment,UE)通过电子保障措施(Electronic Support Measures,ESM)过程建立默认的增强分组服务承载上下文(EPS BEARER CONTEXT),该承载上下文除了显示去激活或网络隐式去激活外,在S1连接和无限资源控制模块(Radio Resource Control,RRC)连接释放时用户体验(User Experience,UE)侧和移动管理实体(Mobile Managenment Entity,MME)侧上下文均不会释放,当连接释放后用户进入ECM-IDLE模式,后续若该用户需要传输缓存上行数据或信令或是网络有缓存下行数据发送时,可能通过Service Request过程或TAU过程来转换到ECM-CONNECTED模式,并在Service Request过程中或在TAU过程结束后通过初始上下文建立过程建立S1和空口承载, 从而进一步进行数据业务。 In the prior art, a user equipment (User Equipment, UE) to establish a default bearer context enhanced packet service (EPS BEARER CONTEXT), the bearer context deactivation or addition to the display of hidden electronic safeguards (Electronic Support Measures, ESM) process deactivation outside, and the S1 connection unlimited resource control module (Radio resource control, RRC) connected user experience (user experience, UE) side and a mobility management entity (mobile Managenment entity, MME) context release side are not released, when the connection is released by the user into the ECM-IDLE mode, if the user needs to follow the transmit buffer or the uplink data or signaling network has buffers downlink data transmission, may be converted into the ECM-cONNECTED mode Service Request procedure or TAU procedure, and service Request or established during the TAU procedure after the end of the process of establishing the initial context S1 and the carrier air interface, so that further data traffic.

[0003] 根据协议,若初始上下文建立过程中,若由于E-UTRAN无线接入控制或是终端重配失败或终端重配完成消息未成功发送到演进的基站(eNodeB)等原因,最终导致初始上下文过程建立失败,eNodeB和MME的行为协议未明确,eNodeB和MME两个节点分别进行各自的隐式释放或是Mffi发起的UE Context Release都可以接受,只要保证eNodeB侧的资源释放即可。 [0003] According to the agreement, if the initial context setup procedure, since if the E-UTRAN radio access control terminal, or a terminal or reconfiguration failed reconfiguration complete message is not sent to an evolved base station (eNodeB) success and other reasons, resulting in initial the context of the process of building failures, eNodeB and MME's behavior not expressly, eNodeB and MME two nodes were their implicit release or Mffi initiated UE context release are acceptable, as long as eNodeB side resources can be released.

[0004] 现有技术至少会存在以下问题: [0004] prior art, there will be at least the following questions:

[0005] (1)若是终端重配完成消息未成功发送,终端不断重传该消息,到达最大重传次数后,发起RRC连接重建,因为eNodeB侧UE上下文已经删除故重建不能成功。 After [0005] (1) If the terminal reconfiguration complete message was not successfully transmitted, the terminal continues retransmitting the message reaches the maximum number of retransmissions, initiate RRC connection reestablishment, because side eNodeB the UE context has been deleted so that the reconstruction can not be successful. 重建被网络拒绝后离开RRC_C0NNECTED态,并且底层指不' RRC connect ion fai lure '的RRC释放原语后,终端继续发起TAU过程以实现NAS信令连接恢复,而MME侧上下文已经释放,所以TAU Request 也会被网络以' Implicitly detached'原因拒绝。 Reconstruction is rejected by the network after leaving RRC_C0NNECTED state, and the bottom layer does not refer to the 'RRC connect ion fai lure' RRC release of primitives, the terminal initiates a TAU procedure to continue to achieve the NAS signaling connection restored, and the side MME context is already released, the Request TAU to the network will be rejected 'implicitly detached' reasons.

[0006] (2)若是Service Request过程中网络侧无线接入控制原语导致所有的无线承载均无法建立,UE不知道MME侧上下文已被去激活,只收到eNodeB的原因为' other '的RRC连接释放消息而结束本次Service Request过程,后续用户若重新发起Service Request请求业务恢复,均会因为MME侧找不到上下文而被网络以〃Implicitly detached〃原因拒绝。 [0006] (2) if the Service Request process control network radio access primitive causes all radio bearers are not established, the UE does not know the side MME context has been deactivated, the eNodeB received only reason for the 'other' of RRC connection release message and ends the process of service request, if a subsequent user request to reinitiate service request service restoration, because no context will be the network side MME 〃Implicitly detached〃 reason to reject.

[0007] 以上均会增加不必要的信令交互过程,浪费信令资源,同时延长了业务恢复时间。 [0007] above will add unnecessary signaling interaction process, signaling a waste of resources, while extending the service restoration time.
