Abstract

本发明实施例提供一种数据包传输的方法和设备,涉及通信领域,以降低在数据传输过程中,对基站造成的存储负担。该方法包括:UE的服务基站获取小数据包的指示信息,该UE的服务基站在接收到该UE发送的无线资源控制消息后,根据该小数据包的指示信息从该核心网设备获取该小数据包,并将该小数据包发送至该UE。本发明实施例用于数据包的传输。

Description

一种数据包传输的方法和设备 技术领域
本发明涉及通信领域, 尤其涉及一种数据包传输的方法和设备。 背景技术
MTC ( Machine Type Communications, 机器类通信 ) 应用是指 一个或多个网元之间在不需要人为参与的情况下进行的数据传输, 现 有 技 术 中 , 当 核 心 网 设备接 收 到 MTC ( Machine Type Communications, 机器类通信) 服务器发送的小数据包时, 按照以 下步骤将该小数据包传输至 UE ( User Equipment, 用户设备), 其 中, 小数据包指的是数据包较小且发送的数据量较少, 往往通过一 个或几个包即可完成数据的传输。 由于小数据包的数据量比较小, 因此, 传输的时间也比较短, 没有必要为这些数据包建立数据通道。
51、 核心网设备向 UE的服务基站发送第一寻呼消息, 其中, 该 第一寻呼消息包括该小数据包, 该核心网设备可以是 MME( Mobility Management Entity, 移动性管理实体),
52、 该 UE的服务基站向该 UE发送第二寻呼消息, 以便该 UE根 据该第二寻呼消息向该 UE 的服务基站发送 RRC ( Radio Resource Control, 无线资源控制协议) 连接建立请求消息。
53、 该 UE的服务基站在接收到该送 RRC连接建立请求消息后, 向该 UE发送 RRC连接建立消息, 其中, 该连接建立消息包括该小数 据包。
由以上步骤可知, 核心网设备在发送至 UE的寻呼消息中包括小 数据包, 这样, 当 UE在根据第二呼叫请求消息进行 RRC连接建立的 过程中, UE 的服务基站将该小数据包发送至该 UE, 但是, 如果 UE 的服务基站在发送第二寻呼消息后, UE 长时间没有响应, 该 UE 的 服务基站会再次发送该第二寻呼消息, 这个过程会导致小数据包在 UE 的服务基站下保存较长的时间, 当该 UE 的服务基站需要发起多 个 U E 的小数据包的呼叫时, 緩存的小数据包太多会增加 UE 的服务 基站的存储负担, 从而影响服务基站数据的传输。 另外, 当核心网 设备发起寻呼时, 会向该 UE注册过的所有 TA ( T r a c k i n g A r e a ) 位 置区下的基站, 发送包括小数据包的第一寻呼消息, 接收到第一寻 呼消息的所有基站, 都会在自 己基站下的小区中去呼叫该 U E , 在呼 叫 U E 的过程中, 基站会緩存 UE 的小数据包。 因此, 緩存的小数据 包同样会增加 UE的非服务基站的存储负担。
发明内容
本发明提供一种数据包传输的方法和设备, 以降低在数据传输 过程中, 对基站造成的存储负担。
