Description

小数据包的传输方法、 基站和用户设备 技术领域
本发明实施例涉及通信技术领域, 尤其涉及一种小数据包的传输方法、 基站和用户设备。 背景技术
长期演进 (Long Term Evolution , LTE)是第 3代合作伙伴计划主导的通 用移动通信系统技术的长期演进, 它能够为用户提供更高的数据传输速 率。 这一优势使它更适用于大数据包的传输。 用户设备 (User Device, UE) 在 LTE发起业务传输数据的大致流程为:先建立信令无线承载 l(Signaling Radio Bearer, SRB1) , 进入无线资源控制(Radio Resource Control, RRC) 连接状态, 再建立 SRB2和数据无线承载 (Data Radio Bearer, DRB;)。 由 于 SRB1和 SRB2都属于信令无线承载, 其中 SRB1用于传输 RRC消息, SRB2用于传输非接入层 (Non-Access Stratum, NAS)消息; 由于 DRB属 于数据无线承载, 所以 DRB用于传输 UE的业务数据。
在多媒体电话通信 (Multimedia Telephone Communication, MTC)类型 通信中, 由于传输的数据包的数量或大小比较小, 如果还使用现有 LTE 系统中的业务建立流程, 会导致大量的信令开销, 而实际传输了少量小的 数据包。
为了节省 LTE系统中业务建立流程带来的信令开销,现有技术中,将 小数据包封装在非接入层 (Non-Access Stratum, NAS)消息中, 通过信令无 线承载 (Signaling Radio Bearer, SRB)传输 NAS消息。 然而, 基站无法区 分用户设备 (User Equipment, UE)传输的是 NAS消息还是小数据包, 从而 降低了基站调度 UE传输的准确性, 影响系统性能。 发明内容

歩骤 101, 基站接收用户设备发送的无线资源控制 RRC连接请求, 该 RRC 连接请求包含第一指示信息,该第一指示信息用于向基站指示小数据包传输。 本发明实施例中,用户设备需要传输小数据包的场景下,可以通过在 RRC 连接请求中携带第一指示信息来指示基站用户设备需要进行小数据包的传 输。其中所述第一指示信息具体可以是在 RRC连接请求消息中的建立原因中, 增加的一个原因值, 来指示小数据包传输, 或者在 RRC连接请求消息中增加 的新的信息元素, 来指示小数据包传输, 或者在 RRC连接请求消息所封装的 媒体接入控制层协议数据单元(Media Access Control Protocol Data Unit, MAC PDU) 增加的新的控制单元, 来指示小数据包传输, 或者在 RRC连接请求消 息所封装的 MAC PDU中的预留比特,来指示小数据包传输。本发明不作限制。 歩骤 102, 基站向该用户设备发送 RRC连接建立消息, 该 RRC连接建立消 息中携带为传输 RRC消息所分配的第一无线承载 RB的配置信息, 以及为小数 据包传输所分配的第二无线承载 RB的配置信息,该第二 RB是根据第一指示信 息为小数据包传输建立的第二 RB,第二 RB的配置信息用于为用户设备建立第 二 RB提供参数。
