无线承载管理方法、装置及***Radio bearer management method, device and system

技术领域Technical field

本发明实施例涉及通信领域，特别涉及一种无线承载管理方法、装置及***。The embodiments of the present invention relate to the field of communications, and in particular, to a radio bearer management method, apparatus, and system.

背景技术Background technique

随着物联网的发展，智能仪表仪器类的终端设备可通过基于蜂窝的窄带物联网(Narrow Band Internet of Things,NB-IoT)接入基站。With the development of the Internet of Things, terminal devices of the smart instrumentation class can access the base station through a cellular-based Narrow Band Internet of Things (NB-IoT).

在终端设备与基站进行数据交互前，终端设备先与基站建立无线资源控制(Radio Resource Control，RRC)连接。在建立RRC连接之后，终端设备通过该RRC连接将数据发送给基站，或者，终端设备通过该RRC连接从基站接收数据。当终端设备和基站之间不需要进行数据交互时，终端设备和基站可以将该RRC连接暂时挂起。所谓“挂起该RRC连接”，是指终端设备和基站分别保存该RRC连接上下文并释放掉该RRC连接。之后，当终端设备和基站之间再次进行数据交互时，终端设备和基站可以恢复该RRC连接。所谓“恢复该RRC连接”，是指终端设备和基站根据之前保存的RRC连接的上下文信息，将已经释放掉的RRC连接进行重新建立。Before the terminal device performs data interaction with the base station, the terminal device first establishes a Radio Resource Control (RRC) connection with the base station. After establishing the RRC connection, the terminal device transmits data to the base station through the RRC connection, or the terminal device receives data from the base station through the RRC connection. When no data interaction is required between the terminal device and the base station, the terminal device and the base station may temporarily suspend the RRC connection. The phrase "suspend the RRC connection" means that the terminal device and the base station respectively save the RRC connection context and release the RRC connection. Thereafter, when data interaction is performed again between the terminal device and the base station, the terminal device and the base station can resume the RRC connection. The "recovering the RRC connection" means that the terminal device and the base station re-establish the RRC connection that has been released according to the previously saved context information of the RRC connection.

一个RRC连接中的无线承载通常包括多个无线承载，挂起该RRC连接时会挂起该RRC连接中的所有无线承载，恢复该RRC连接时也会恢复该RRC连接中的所有无线承载。然而，并不是每一个RRC连接被恢复后，该RRC连接上的所有无线承载都会被终端设备与基站所使用。A radio bearer in an RRC connection usually includes multiple radio bearers. When the RRC connection is suspended, all radio bearers in the RRC connection are suspended. When the RRC connection is resumed, all radio bearers in the RRC connection are also restored. However, not every RRC connection is restored, all radio bearers on the RRC connection are used by the terminal device and the base station.

The E-RAB identifier corresponding to the identifier is the E-RAB identifier requested to be released.

步骤302，MME接收接入网设备发送的终端设备上下文挂起请求消息。Step 302: The MME receives a terminal device context suspension request message sent by the access network device.

步骤303，MME向接入网设备发送终端设备上下文挂起响应消息，终端设备上下文挂起响应消息携带有：MME指示挂起和/或释放的E-RAB标识。Step 303: The MME sends a terminal device context suspension response message to the access network device, where the terminal device context suspension response message carries: the E-RAB identifier that the MME indicates to suspend and/or release.

当终端设备上下文挂起请求消息携带有接入网设备请求挂起的E-RAB标识时，MME根据终端设备上下文挂起请求消息确定指示挂起和/或释放的E-RAB标识：When the terminal device context suspension request message carries the E-RAB identifier that the access network device requests to suspend, the MME determines the E-RAB identifier indicating the suspension and/or release according to the terminal device context suspension request message:

MME根据终端设备上下文挂起请求消息中包括的接入网设备请求挂起的E-RAB标识，确定指示挂起的E-RAB标识，指示挂起的E-RAB标识与接入网设备请求挂起的E-RAB标识相同；或者，指示挂起的E-RAB标识是接入网设备请求挂起的E-RAB标识的子集。The MME requests the suspended E-RAB identifier according to the access network device included in the terminal device context suspension request message, and determines the suspended E-RAB identifier, indicating that the suspended E-RAB identifier and the access network device request to hang. The E-RAB identifier is the same; or the E-RAB identifier indicating the suspension is a subset of the E-RAB identifier that the access network device requests to suspend.

和/或，MME根据终端设备上下文挂起请求消息中包括的接入网设备请求释放的E-RAB标识，确定指示释放的E-RAB标识，指示释放的E-RAB标识与接入网设备请求释放的E-RAB标识相同；或者，指示释放的E-RAB标识是接入网设备请求释放的E-RAB标识的子集。And/or, the MME determines, according to the E-RAB identifier that is requested by the access network device that is included in the terminal device context suspension request message, to indicate the released E-RAB identifier, and indicates the released E-RAB identifier and the access network device request. The released E-RAB identifier is the same; or the E-RAB identifier indicating the release is a subset of the E-RAB identifier requested by the access network device to be released.

当接入网设备发送的终端设备上下文挂起请求消息中不携带接入网设备请求挂起和/或释放的E-RAB标识时，由MME自行确定指示挂起和/或释放的E-RAB标识。When the terminal device context suspension request message sent by the access network device does not carry the E-RAB identifier requested by the access network device to suspend and/or release, the MME determines the E-RAB indicating the suspension and/or release. Logo.
