Abstract: In a communication method, a base station may use a wake-up signal (WUS) to carry an indication indicating a cell managed by the base station. A terminal device in a non-connected state receives the WUS, and this indicates that the terminal device is in a coverage area of the cell indicated by the indication. Then, the terminal device may listen to paging or initiate random access in the cell. According to the method, the terminal device in the non-connected state may determine, by using the WUS, whether the terminal device is still in a coverage area of a cell on which the terminal device previously camps, to implement mobility management. Further, after receiving the WUS, the terminal device in the coverage area of the cell indicated by the indication included in the WUS may listen to paging or initiate random access in the cell.

Abstract: This application discloses a gateway configuration method and a gateway device, so as to resolve problems of a relatively heavy configuration workload, update inflexibility, and low configuration efficiency that exist when an OM entity is used to uniformly configure gateways in an LTE system. The method includes: configuring, by a control plane gateway, a parameter for a user plane gateway, and sending, by the control plane gateway, a configuration message to the user plane gateway, where the configuration message carries the configuration parameter configured by the control plane gateway for the user plane gateway. In this application, the control plane gateway configures the parameter for the user plane gateway, so that the control plane gateway implements configuration of the user plane gateway, and configuration flexibility and configuration efficiency are improved.

Abstract: The present disclosure relates to a QoS guarantee method. In one example method, a control plane gateway obtains a QoS parameter. The QoS parameter comprises an allocation/retention priority (ARP) and a QoS class identifier (QCI). The control plane gateway maps the QoS parameter to QoS guarantee information. The QoS guarantee information comprises a differentiated services code point (DSCP) parameter. The control plane gateway sends the QoS guarantee information to a user plane gateway. The QoS guarantee information is to be used by the user plane gateway for QoS marking.
