Machine to Machine ( M2M )狭义上的定义是机器到机器的通信。 广义 上的定义是以机器终端智能交互为核心的、 网络化的应用与服务。 M2M基 于智能机器终端, 以多种通信方式为接入手段, 为客户提供信息化解决方案, 以满足客户对监控、 指挥调度、 数据釆集和测量等方面的信息化需求。 无线技术的发展是 M2M市场发展的重要因素。 无线技术突破了传统通 信方式的时空限制和地域障碍, 使企业和公众摆脱了线缆束縛, 让客户更有 效地控制成本、 降低安装费用并且使用简单方便。 另外, 日益增长的需求推 动着 M2M不断向前发展。 与信息处理能力及网絡带宽不断增长相矛盾的是 信息获取的手段远远落后。 而 M2M很好的满足了人们的这一需求, 通过它 人们可以实时监测外部环境, 实现大范围、 自动化的信息采集。 因此, M2M 可以应用于行业应用、 家庭应用以及个人应用等。 行业应用如: 交通监控、 告警系统、 海上救援、 自动售货机及开车付费等。 家庭应用如: 自动抄表及 温度控制等。 个人应用如: 生命检测及远端诊断等。
M2M 的通信对象为机器对机器和人对机器。 一个或多个机器之间的数 据通信定义为机器类型通信 ( Machine Type Communication, MTC ) , 这种 情况下较少需要人机互动。 参与 MTC的机器, 定义为 MTC设备。 MTC设 备是 MTC 用户的终端, 可通过公共陆地移动网络 (Public Land Mobile Network, PLMN )网络与 MTC设备、 MTC服务器进行通信。用户设备( User Equipment, UE )为 MTC设备附带的功能块, 该功能块用于将 MTC设备接 入到移动通信系统。 MTC服务器( MTC Server )对 MTC设备进行管理和监 控。图 1、 2分别为现有技术中 MTC UE通过通用陆地无线接入网络( Universal
Terrestrial Radio Access Network, UT AN ) 、 演进的通用陆地无线接入网络 ( Evolved UTRAN , E-UT AN )接入核心网(Core Network , CN)的示意图。 由于 MTC设备大都为具体的应用设备, 如自动抄表与生命检测使用的 是不同的设备等。 不同应用的 MTC设备具有不同的特性, 如电梯等升降机 设备具有低移动性以及只有包交换(Packet Switch only, PS only ) 等属性, 而监视和警报设备除具有低移动性和 PS only特性外, 还具有低数据传输和 高可用性等属性。 因此针对不同应用的 MTC设备进行不同的系统优化, 可 有效的对 MTC设备进行管理、 监控和付费等。

本发明的较佳实施方式
本发明的发明构思是: 无线接入网和核心网初始化完成后, 由核心网发 起公共承载建立或由无线接入网请求建立公共承载, 所述无线接入网和核心 网建立两者之间的公共承载后 , 使用所述公共承载进行多个 MTC UE的上、 下行数据传输。 无线接入网和核心网可以在上电、 初始化完成后建立公共承载, 或者在 重启、 初始化完成后建立公共^ L载。 当 MTC UE请求进行上行数据传输时,无线接入网对 MTC UE要传输的 数据进行判断, 对于满足预定条件的数据使用已建立的公共承载进行数据传 输, 否则为该 MTC UE建立专用数据承载进行上行数据传输。 所述预定条件可以是数据量条件或者数据类型条件等数据属性条件, 例 如, 无线接入网根据所要传输的数据的数据量, 决定是否采用公共承载进行 数据传输, 如果数据量较大, 即数据量超过预定门限, 则为该 MTC UE建立 专用的数据承载, 如果数据量较小, 即数据量低于预定门限, 则直接使用已 经建立的公共承载进行数据传输。 具体过程参见图 3流程, 包括: 步骤 301, 无线网络控制器( Radio Network Controller, RNC )和核心网 ( Core Network , CN )之间建立公共承载; 本文所述公共承载是指供多个 MTC UE共同使用的承载, 并非针对某一 个 MTC UE的承载。 步骤 302, MTC UE发送数据传输请求, 请求进行数据传输; 步骤 303 , RNC根据经基站( Node B, B )转发的 UE需要传输的数据 的数据量判断是否需要建立专用地面承载, 如果是, 执行步骤 304, 如果否, 执行步骤 305; 步骤 304, NC建立专用的地面承载进行数据传输;
建立专用地面承载的过程可采用现有标准中规定的流程进行, 不是本发 明重点, 不做赘述。 步骤 305, NC用已建立的公共承载进行数据传输。 但也不排除无线接入网对于所有 MTC UE的数据均使用该公共承载进行 数据传输的情况, 此时, 上述预定条件可设为空。 为某 MTC UE建立专用数据承载进行上行数据传输后, 针对该 UE的下 行数据, 如果满足上述预定条件, 也可采用公共承载进行下行传输。
下面结合附图和具体实施例对本发明所述技术方案作进一步的详细描 述, 以使本领域的技术人员可以更好的理解本发明并能予以实施, 但所举实 施例不作为对本发明的限定。 实施例一 图 4是 MTC UE通过 UTRAN系统接入, RNC和 CN之间公共承载的建 立流程, 具体包括如下步骤: 步骤 401 : UTRAN和 CN分别上电, 完成初始化过程; 步骤 402: 初始化过程完成之后, CN向 UTRA 发送承载建立消息, 请 求 UTRAN建立和 CN之间的地面承载; 承载建立消息中, 需要携带所要建 立的承载的服务质量(Quality of Service, QoS )参数、 传输层信息 (例如传 输层地址)、 GPRS隧道协议隧道节点标识( GPRS Tunneling Protocol Tunnel End Point Identifier, GTP TEID )等;
UTRAN和 CN之间建立的地面承载可能为一个或多个, 如果建立多个, 则需要在承载建立消息中携带建立承载的个数。
本步骤可以在 CN初始化过程完成之后触发, 也可以在 CN第一次需要 发送相关的下行数据时触发。 步骤 403: UTRAN收到 CN发来的承载建立消息后, 根据其中携带的需 要建立的承载个数以及 QoS参数、 传输层地址和 GTP TEID等信息建立和
CN之间的地面承载;
上述地面承载不是为一个用户一次数据传输而建立的, 是所有 MTC设 备进行数据传输都可以使用的公共承载。 步骤 404: 承载建立完成之后, UTRAN向 CN返回承载建立完成消息。 如果同时建立了多个承载的话, 则需要在承载建立完成消息中分别指明 哪些承载建立成功, 哪些承载建立失败。
MTC设备需要进行数据传输时, RNC根据需要传输的数据量, 决定是 否需要建立专用的地面承载。 对于数据量较大的业务, 为用户建立专用的地 面承载; 数据量较小的业务, 不需建立专用的地面承载, 使用已有的公共承 载进行数据传输。

MME在承载建立消息中携带所要建立的承载的 QoS参数、 传输层信息 (例如传输层地址) 、 GTP TEID以及所建立的承载个数(可选) ; 步骤 503: eNodeB收到 MME发来的承载建立消息后, 根据其中携带的 信息建立和 MME之间的公共承载; 步骤 504: eNodeB向 MME返回承载建立完成消息。

步骤 604: CN根据 UTRAN的请求发起承载建立消息, 命令 UTRAN建 立相应的公共? 载; 步骤 605: UTRAN收到 CN发来的承载建立消息后, 根据其中携带的需 要建立的承载个数以及 QoS参数、 传输层地址和 GTP TEID等信息建立和 CN之间的公共承载; 步骤 606: 承载建立完成之后, UTRAN向 CN返回承载建立完成消息。

实施例五 图 8为 MTC UE通过 UTRAN系统接入, CN发起的公共承载释放的流 程, 具体包括如下步骤: 步骤 801 : CN判断其与 UTRAN之间的某条公共承载是否满足释放条件, 如果是, 向 UTRAN发送承载释放消息; 所述释放条件例如可以是是否到达公共承载的老化时间, 或者公共承载 是否出现故障, 或者公共承载的误码率是否到达预设门限等。 如果建立了多条公共承载, 且同时有多条公共满足释放条件, 则可以同 时释放多条公共承载。 步骤 802: UTRAN收到 CN的承载释放消息后, 执行释放操作, 释放
