Abstract:
This application provides a communication method and a communication apparatus. The communication method includes: An access stratum of a terminal device receives a quality of experience QoE measurement result and first indication information from an upper layer of the access stratum. The access stratum of the terminal device determines, based on the first indication information, to send the QoE measurement result to a master node or a secondary node of the terminal device. Therefore, in this application, the upper layer of the access stratum of the terminal device sends, to the access stratum, the QoE measurement result and the first indication information corresponding to the QoE measurement result, so that the terminal device in the MR-DC architecture can send the QoE measurement result to the correct access network device.
Abstract:
A first terminal obtains a plurality of first relative positions. Each of the plurality of first relative positions is determined based on a second relative position and a third relative position. The first relative position is an initial relative position between the first terminal and a second terminal, the second relative position is a relative position between the first terminal and a reference point, and the third relative position is a relative position between the second terminal and the reference point. The first terminal processes the plurality of first relative positions, to obtain a relative position between the first terminal and the second terminal.
Abstract:
This application provides a reflective QoS flow characteristic-based communications method and apparatus. In the method, an access-network network element sends first information to a core-network network element, where the first information is used to indicate whether a data packet has a reflective QoS flow characteristic; and the access-network network element determines, based on the first information, whether there is a need to send a QoS flow identifier to a terminal. In this way, signaling overheads are reduced.
Abstract:
The present disclosure relates to communication methods and apparatus. On one example method, a terminal device obtains measurement results of N cells, where the N cells include M non-public network cells, where N is an integer greater than or equal to 1, and where M is an integer greater than or equal to 0. The terminal device determines, based on the measurement results of the N cells and measurement result offset values corresponding to H first cells in the N cells, a target cell on which the terminal device is to camp, where H is an integer greater than or equal to 1, and where H≤N.

Embodiments of the present invention provide a communication method and a communications device. The method includes: sending, by a base station, a message including measurement configuration to UE, where the measurement configuration is used to request the UE to report a cell global identifier of a cell; obtaining, by the base station, a measurement report reported by the UE, where the measurement report corresponds to the measurement configuration and includes the cell global identifier of the cell and band information of the cell; and performing, by the base station, cell handover based on the band information and the cell global identifier of the cell. By means of the present invention, the base station obtains complete and accurate band information of the cell, so that the base station can perform accurate handover decision, thereby avoiding handover failure.
Abstract:
The present disclosure relates to a notification method. In one example method, a first base station configures a first cell identity for a first cell. The first cell identity comprises a first identifier field and a second identifier field. A reserved bit in the second identifier field and the first identifier field identify the first base station. A remaining bit in the second identifier field identifies the first cell. The first base station notifies a second base station or a core network device of a part of the first cell identity that identifies the first base station.
Abstract:
A radio release control (RRC) connection release method includes: sending, by user equipment (UE), a first message to a base station, where the first message carries a preset RRC release time determining parameter or a first RRC release time; if the UE adds the first RRC release time to the first message, setting, by the UE, timing duration of a first timer based on the first RRC release time, and starting the first timer; and releasing, by the UE, an RRC connection when the first timer expires.
