Abstract: Embodiments of the present invention provide an RRC connection method and an apparatus. The method includes: receiving, by a terminal, a deactivation indication message sent by a first base station, where the deactivation indication message carries indication information relating to mobility control of the terminal, and the first base station is a serving base station of the terminal; and releasing, by the terminal, an RRC connection according to the deactivation indication message, reserving context information of the terminal, and entering an inactive state. In this solution, the context information of the terminal does not need to be released, so that when entering a connected state again, the terminal does not need to obtain the context information again, thereby reducing signaling overheads.

Abstract: This disclosure describes an IP address allocation method and apparatus, and a system. Specifically, when there is a relay device between an address request device and an address allocation device, and the address request device requests an IPv6 address, a request packet sent by the address request device to the address allocation device includes an interface identifier negotiated with the relay device. After receiving the request packet, the address allocation device may allocate the IPv6 address based on the interface identifier in the request packet, where the IPv6 address includes the interface identifier; and send the IPv6 address to the address request device by using a response packet.

Abstract: A first node sends, after determining that all data packets from a migrating IAB node are received, first indication information to a source IAB donor CU. The first node is an upstream IAB node of a source parent node of the migrating IAB node or is a source IAB donor DU, the source IAB donor CU is an IAB donor CU connected to the migrating IAB node before migration, and the source IAB donor DU is an IAB donor DU connected to the migrating IAB node before the migration. The first node receives second indication information from the source IAB donor CU. The first node updates or releases, based on the second indication information, backhaul configuration information that corresponds to the migrating IAB node and that is on a backhaul link between the first node and a child node of the first node.

Abstract: This application provides a communication method. The method includes: When a radio link failure RLF occurs on a first communication device connected to a first donor network device, the first communication device performs an RLF recovery process, and connects to a second donor network device. The first communication device determines that the first donor network device and the second donor network device are different network devices. The first communication device sends first information to a second communication device, where the first information indicates the second communication device to send a radio resource control RRC re-establishment request message, or indicates the second communication device to obtain system information sent by the first communication device.

Abstract: Example configuration methods and apparatus are described. An example communications system includes a master node and a secondary node that jointly provide a service for a terminal. One example method includes generating configuration information for a signaling radio bearer (SRB) by the secondary node, where the SRB is used to transmit a radio resource control (RRC) message between the secondary node and the terminal. The secondary node sends the configuration information for the SRB to the master node, so that the configuration information for the SRB is sent to the terminal through the master node. The secondary node receives a result of configuring the SRB by the terminal by using the configuration information for the SRB. In this way, the SRB can be established on the secondary node, and used for RRC message transmission between the secondary node and the terminal.
