Abstract: An access network device determines to add, for a remote terminal device, a direct path for connecting a first cell. The remote terminal device is connected to a second cell through an indirect path. The access network device sends an RRC reconfiguration message to indicate the remote terminal device to switch to the direct path. The RRC reconfiguration message further indicate not to release the indirect path. When being indicated to switch to the direct path, the remote terminal device may further be indicated not to release the indirect path.

Abstract: A first network device receives first information from a second terminal device or a third network device, where the first information includes an identifier of a first terminal device, and the third network device is a network device on which the second terminal device camps. The first network device sends the identifier of the first terminal device to a second network device, where the identifier of the first terminal device is usable to determine whether the first terminal device is authorized to provide a relay service. The first network device receives second information from the second network device, where the second information indicates whether or not the first terminal device is authorized to provide a relay service.

Abstract: This application provides a data processing method and apparatus, and a computer storage medium. When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and the PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity. Data corresponding to the first SDU is redelivered, to avoid a data packet loss caused by preprocessing of the PDCP entity.

Abstract: A timer control method includes a receiving device that performs re-establishment or data recovery on a Packet Data Convergence Protocol (PDCP) layer of the receiving device. The PDCP layer stops the running of a reordering timer of the PDCP layer when the reordering timer is in a running state, where the reordering timer enables the PDCP layer to wait to receive a lost data packet. Because the reordering timer is stopped from running rather than expires, the PDCP layer does not update a value of RX_DELIV.

Abstract: A communication method includes that a first device deletes a first data packet. The first device sends first signaling to a second device, where the first signaling includes or indicates a first buffer, the first buffer is used to compress a second data packet or used to decompress a compressed second data packet, a serial number of the first data packet and a serial number of the second data packet are consecutive, the serial number of the second data packet follows the serial number of the first data packet, and the second device is a receiving device of the compressed second data packet.

Abstract: This application provides a pending SR cancellation method and an apparatus. In the method, when a specific condition is met, a terminal cancels a pending SR triggered by an uplink BSR, and when some other conditions are met, the terminal cancels a pending SR triggered by a sidelink BSR. In other words, the terminal may independently cancel the SR triggered by the uplink BSR and the SR triggered by the sidelink BSR. When canceling the SR triggered by the uplink BSR, the terminal may not cancel the SR triggered by the sidelink BSR, so that when sidelink data has a relatively high latency requirement.
