In this way, the network device can learn that the terminal device needs to release the radio resource control connection based on the above information. , thereby sending the first message to the terminal device.
S202、终端设备从业务载波切换到锚点载波，接收网络设备发送的星历信息相关的系统消息。S202. The terminal device switches from the service carrier to the anchor carrier, and receives system messages related to ephemeris information sent by the network device.
其中，终端设备可在接收第一消息时，从业务载波切换到锚点载波(即释放无线资源控制连接，从连接态切换到空闲态)，以接收网络设备发送的星历信息相关的系统消息。Wherein, when receiving the first message, the terminal device may switch from the service carrier to the anchor carrier (ie, release the radio resource control connection and switch from the connected state to the idle state) to receive the system message related to the ephemeris information sent by the network device. .
可选地，星历信息相关的系统消息是网络设备周期性的向小区内的终端设备广播的。Optionally, system messages related to ephemeris information are periodically broadcast by the network device to the terminal devices in the cell.

在另一种可选的实施方式中，终端设备在执行步骤S201之前，即接收来自网络设备的第一消息之前，且该终端设备处于空闲态时，还包括：接收包括定时器的定时时长配置信息的系统消息，该定时器用于在接收第一消息后启动，以确定在定时器超时之前是否完成接收星历信息相关的系统消息；相应的，网络设备发送包括定时器的定时时长配置信息的系统消息，该定时器用于发送第一消息后启动，以确定在定时器超时之前是否接收到终端设备发送的回复无线资源控制连接的请求消息。In another optional implementation, before the terminal device performs step S201, that is, before receiving the first message from the network device, and when the terminal device is in an idle state, the terminal device further includes: receiving a timing duration configuration including a timer. Information system message, the timer is used to start after receiving the first message to determine whether the system message related to the ephemeris information has been received before the timer times out; accordingly, the network device sends a timer including the timing duration configuration information of the timer. System message. This timer is used to start after sending the first message to determine whether a request message sent by the terminal device to reply to the radio resource control connection is received before the timer times out.
终端设备在接收第一消息后，可启动定时器，并从业务载波切换到锚点载波，接收星历信息相关的系统消息。可选地，在定时器超时之前，若完成接收星历信息相关的系统消息，则恢复无线资源控制连接；若未完成接收星历信息相关的系统消息，则向网络设备发起无线资源控制连接的连接建立。相应的，在定时器超时之前，若网络设备接收到终端设备发送的恢复无线资源控制连接的请求消息，则确定恢复无线资源控制连接；否则，网络设备将释放终端设备的上下文信息、预留的无线资源。After receiving the first message, the terminal device can start the timer, switch from the service carrier to the anchor carrier, and receive system messages related to ephemeris information. Optionally, before the timer times out, if the reception of the system message related to the ephemeris information is completed, the radio resource control connection is restored; if the reception of the system message related to the ephemeris information is not completed, the radio resource control connection is initiated to the network device. The connection is established. Correspondingly, before the timer times out, if the network device receives the request message sent by the terminal device to restore the radio resource control connection, it will determine to restore the radio resource control connection; otherwise, the network device will release the context information of the terminal device and the reserved Wireless resources.
需要说明的是，在定时器超时之前，若终端设备完成接收星历信息相关的系统消息，则可恢复无线资源控制连接的原因是：定时器超时之前，网络设备会保留之前分配给终端设备的无线资源，同时维持终端设备的上下文信息，从而当终端设备需要收发数据时，可根据上下文信息快速恢复无线资源控制连接(即恢复到连接态)。若终端设备未完成接收星历信息相关的系统消息，则向网络设备发起无线资源控制连接的连接建立的原因是：定时器超时之后，网络设备会释放预留给终端设备的无线资源以及终端设备的上下文信息，因此，当终端设备需要收发数据时，需重新建立无线资源控制连接(即向网络设备发起无线资源控制连接的连接建立)。It should be noted that before the timer times out, if the terminal device completes receiving system messages related to ephemeris information, the reason why the radio resource control connection can be restored is: before the timer times out, the network device will retain the information previously allocated to the terminal device. Wireless resources, while maintaining the context information of the terminal device, so that when the terminal device needs to send and receive data, it can quickly restore the wireless resource control connection (ie, restore to the connected state) based on the context information. If the terminal device has not completed receiving the system messages related to the ephemeris information, the reason for initiating the connection establishment of the wireless resource control connection to the network device is that after the timer times out, the network device will release the wireless resources reserved for the terminal device and the terminal device. Therefore, when the terminal device needs to send and receive data, it needs to re-establish the radio resource control connection (that is, initiate the connection establishment of the radio resource control connection to the network device).
可选地，终端设备若确定需要收发数据，则可执行该实施方式，根据定时器是否超时以及是否完成该系统消息的接收，确定恢复或重新建立无线资源控制连接，以收发数据；若确定不需要收发数据，则可继续处于空闲态。 Optionally, if the terminal device determines that it needs to send and receive data, it can execute this embodiment and determine to restore or re-establish the radio resource control connection to send and receive data according to whether the timer times out and whether the reception of the system message is completed; if it is determined that it does not If you need to send and receive data, you can continue to be in the idle state.

The first message is used to instruct the terminal device to release the radio resource control connection; the terminal device responds to the first message, switches from the service carrier to the anchor carrier, and receives the satellite. System messages related to historical information. It can be seen that when the terminal device receives the first message, it can switch from the service carrier to the anchor carrier, that is, it is in an idle state, so as to receive system messages related to ephemeris information.
