[0014] 根据不同的网络及网络架构,MTC服务器通过不同的方式与移动性管理单元连接。 [0014] Depending on the network architecture and network, MTC server connected to the mobility management unit in different ways.

[0015] EPS网络中,移动性管理单元为MME,MTC服务器与MME使用直连接口(如图1所示)相连或通过MTC中间网关与MME(如图2所示)相连;在3G网络中,移动性管理单元为SGSN (SERVICING GPRS SUPPORTNODE,GPRS服务支持节点),MTC服务器与SGSN使用直连接口)相连通过MTC中间网关与SGSN相连。 [0015] EPS network, mobility management unit for the MME, and the MME MTC server using a direct connection port (FIG. 1) is connected to or through an intermediate gateway MTC with the MME (FIG. 2); in the 3G network , the mobility management unit is a SGSN (SERVICING GPRS SUPPORTNODE, GPRS support node), SGSN server using MTC straight connecting port) is connected with the SGSN are connected by an intermediate gateway MTC.

[0017] 目前现有分组域网络中,核心网发起的寻呼是针对在线/注册状态的终端,寻呼范围是根据终端当前的移动性管理信息来确定。 [0017] Currently existing packet domain network, the core network initiates paging terminal is for the line / state register, the paging range is determined based on the current mobility management information terminal. 现有寻呼的作用有:核心网有下行数据需要传送到空闲态的终端,使用寻呼通知终端;核心网通过寻呼来广播系统信息变更或广播地震海嘯警报。 Existing paging action are: a core network has downlink data to be transmitted to the terminal in the idle state, the terminal using paging notification; core network to a paging or broadcast system information changes broadcast ETWS.

[0018] 现有技术条件下的分组域寻呼流程,如图4所示,包括以下步骤: [0018] The packet domain in the prior art paging process conditions, as shown in FIG. 4, comprising the steps of:

[0019] 步骤401,触发寻呼MTC终端条件产生时,移动性管理单元向MTC终端注册的基站发送寻呼请求消息,此消息包含终端的身份标识,和寻呼区域等参数; [0019] Step 401, the MTC terminal paging trigger condition occurs, a mobility management unit to register MTC terminal sends a paging request message to the base station, the message comprising terminal identity parameter, paging area, and the like;

[0020] 步骤402,基站按照移动性管理单元的指示对MTC终端进行寻呼; [0020] Step 402, the base station instructs the mobile management unit in accordance with the paging terminals of MTC;

[0021] 步骤403,收到寻呼之后MTC终端发起业务请求流程; [0021] Step 403, after receiving the paging terminal initiates a service request procedure MTC;

[0022] 在一段时间内如果没有收到终端的任何响应,移动性管理单元会尝试重新寻呼。 [0022] In a period of time if no response is received, the mobile terminal management unit will attempt to re-paging.

[0023] 现有技术的寻呼只适用于在线/注册状态的终端,如果终端处理离线/未注册状态,MTC服务器以及核心网网元因没有终端的移动性信息,无法触发移动性管理单元寻呼MTC终端。 [0023] The prior art paging only applicable to online / terminal registration state, if the terminal is offline processing / unregistered state, the MTC core network element and the server by the mobility information is not terminal, the mobility management unit can not trigger hunt call MTC terminal. 3G网络的寻呼过程以及限制与EPS网络基本一致,在此不再复述。 3G networks and paging procedure consistent with the EPS network limitations, not repeat it here.

[0024] 然而随着M2M产业的发展,新的M2M通信要求MTC服务器能够唤醒已经进入离线/未注册状态的MTC终端。 [0024] However, with the development of M2M industry, the new M2M communication requirements can wake MTC MTC server terminal has entered the offline / unregistered state. 而现有技术中的寻呼流程无法满足这样的要求。 The paging process in the prior art can not meet this requirement. 即使是MTC服务器或者MTC用户提供预设的MTC终端所在区域信息给小区广播中心来广播唤醒离线的MTC终端,也存在找不到移动的终端,需要网络运营商架设小区广播中心等弊端。 Even MTC MTC server or users with pre-MTC terminal area information to the cell broadcast center broadcasts wake offline MTC terminal, a mobile terminal can not find there, you need to set up the network operator malpractice cell broadcast center.
