Description

离线通知的方法、系统和设备 Off-line notification, system and apparatus

技术领域 FIELD

[0001] 本发明涉及无线通信领域,尤其涉及一种离线通知的方法、系统和设备。 [0001] The present invention relates to wireless communications, and in particular relates to an offline notification method, system and apparatus.

背景技术 Background technique

[0002] 现有协议中,有以下两种终端在空闲(IDLE)态下链路可达性的判断方案: [0002] in the existing protocol, the following two terminal link reachability determination programs in the idle (IDLE) state:

[0003] 方案一:网络侧的移动性管理实体(MME) /服务GPRS支持节点(SGSN)主动发起区域内寻呼(paging): [0003] Scheme I: a mobility management entity in the network side (MME) / Serving GPRS Support Node (SGSN) within the region initiates paging (Paging):

[0004] 在机器类型通讯设备(MTC Device, MD)处于移动性管理注册(EMM-REGISTERED)态和EPS连接管理空闲(ECM-1DLE)态时,当服务网关(Serving Gateway)接收到机器类型通讯服务器(MTC server)发来的下行数据后,执行如下两个动作:动作一:保留下行数据;动作二:寻找与MD相关联的MME/SGSN的位置。 [0004] when the machine type communications device (MTC Device, MD) at a mobility management registration (EMM-REGISTERED) state and the EPS connection management idle (ECM-1DLE) state, when the serving gateway (Serving Gateway) receives the MTC after the downlink data sent by the server (MTC server), perform the following two actions: action a: reserved downlink data; action II: find the location associated with the MME MD / SGSN of. 该MME/SGSN主动在MD的注册域内寻呼MD,并且试图去建立用户面承载,如果MD接收到MME/SGSN的寻呼,则发起服务请求过程(Service Request procedure),以建立一个无线承载用于发送上行数据至MTC server。 The MME / SGSN registered active domain of paging MD MD, and try to establish a user plane bearer, if MD received MME / SGSN paging is initiated service request procedure (Service Request procedure), to establish a radio bearer with to transmit uplink data to the MTC server. 网络侧接收到MD发送的上行数据后,可以判断出MD在IDLE态的链路可达。 After the network side receiving the uplink data sent from the MD, the MD can be determined that the link up in the IDLE state. 反之,MME/SGSN在维护的寻呼时钟过期前MD对于MME/SGSN发起的寻呼无应答,MME/SGSN会认为此MD在IDLE态的链路不可达,并发送一个关于寻呼失败的下行数据通知拒绝消息(DownlinkDataNotification Reject message)到Serving Gateway。 On the contrary, MME / SGSN before the clock expired paging maintenance for MD MME / SGSN initiates paging no answer, MME / SGSN would think that in this MD unreachable link IDLE state, and sends a downlink on the paging failure data rejection notification message (DownlinkDataNotification reject message) to the Serving Gateway. 此时,Serving Gateway 执行如下两个动作:动作一:删除保存在缓存区(buffer)中的下行数据;动作二:限制控制面去寻呼这个MD。 At this point, Serving Gateway performs the following two actions: Action a: Delete stored in a buffer (buffer) downlink data; Action II: paging to limit the control plane MD.

[0005] 方案二:MD主动上报自己目前的连接状态: [0005] Option Two: MD initiative to report their current connection status:

[0006] 在现有机制中,MD处于EMM-REGISTERED态和EMM-1DLE态时,MD主动触发位置区域更新(TRACKING AREA UPDATE, TAU)过程,TAU的机制之一是,当周期性的位置区域更新时钟(TA update timer)过期时,MD可以主动发起一个TAU过程。 When [0006] In the conventional mechanism, MD in EMM-REGISTERED state and the state EMM-1DLE, MD active trigger location area update (TRACKING AREA UPDATE, TAU) procedure, one of the mechanisms TAU is, when the periodic location area update clock (TA update timer) expires, MD can initiate a TAU procedure. 对于低移动(low mobility)应用场景的MD会发起周期性的位置区域更新过程(tracking area updating procedure)以告知网络侧MD的链路可达。 For low mobility (low mobility) scenarios MD initiates periodic location area update procedure (tracking area updating procedure) to notify the network side of the link up to MD. 另外,对于有移动性需求的MD,当MD发现目前所处的位置区域(TA)不在其注册时网络侧提供的位置区域列表(list of TAs)中时,MD也会发起非周期性的TAU以告知网络侧MD的链路可达。 Further, there is the MD mobility demand, when the current MD discovered which location area (TA) is not in its list location registration area provided by the network (list of TAs) in, also initiates a non-periodic TAU MD to notify the network side of the link up to MD.

[0007] 在现有的TAU体制中,MD发起TAU过程来向MME/SGSN上报自己的链路状况的具体处理流程如下: [0007] In the conventional TAU regime, MD initiate a TAU procedure to report their status to the link MME / SGSN specific process is as follows:

[0008]步骤 1:MD 发起一个TAU 请求(TAU request)到新的MME(New MME)。 [0008] Step 1: MD initiate a TAU request (TAU Request) to the new MME (New MME).

[0009] 步骤2:New MME从原来的MME获取MD的移动性管理(MM)上下文,或MD向NewMME主动上报自己的MM上下文。 [0009] Step 2: New MME MD acquired from the original MME Mobility Management (MM) context, or MD own initiative to report to the MM context NewMME.

[0010] 步骤3:New MME根据丽上下文对MD进行鉴权。 [0010] Step 3: New MME performs authentication in accordance with the MD Li context.

[0011] 步骤4:New MME和Serving GW之间修改和重新建立承载。 [0011] Step 4: Review and New MME between the Serving GW and the re-established bearer.

[0012] 步骤5:New MME进行位置更新和注册过程。 [0012] Step 5: New MME for location updating and registration procedures.

[0013] 步骤6:New MME取消与原来的Serving GW (old Serving GW)之间的网络S1承载。 [0013] Step 6: New MME S1 between the network and the carrier canceled original Serving GW (old Serving GW).

[0014] 当周期性的TAU结束以后,网络侧可以判断MD的链路状态,当MD在IDLE态下链路可达的时候,可以向MD发起机器类型(MT)的网络服务请求(Service Request)并处理来自Serving Gateway的下行数据,同时MD也可以上报自己的上行数据。 [0014] When the end of the TAU periodically, based on the network-side link state MD, the MD when the link up in the IDLE state may be initiated machine type (MT) of the network service request (Service Request to MD ) and processes the downlink data from the Serving Gateway, while MD can report their uplink data.

[0015] 在实现本发明的过程中,发明人发现现有技术中存在以下技术问题: [0015] During the implementation of the present invention, the inventors found that the following technical problems in the prior art:

[0016] 在处于IDLE态的MD的链路不可达时,MTC server或MTC user无法获知该MD的链路不可达的信息,进而无法及时确定该MD是否处于可接受服务状态等。 [0016] When in IDLE state MD link is unreachable, MTC server or MTC user can not know the link is unreachable MD, the MD and thus can not promptly determine whether the service is in an acceptable state and the like.
