Abstract: The present disclosure relates to connection reestablishment methods and apparatus, in one example method, when a handover fails, a terminal reverts back to a source configuration, and obtains a selected cell. The terminal sends a connection reestablishment request to a selected radio access network device. The terminal receives a first message from the selected radio access network device, where the first message includes indication information used to indicate to derive an access network key based on a core network key. The terminal obtains a first core network key based on the indication information, and derives a first access network key based on the first core network key. The terminal communicates with the selected radio access network device by using the first access network key.

Abstract: The present disclosure relates to mode switching methods, data flow splitting methods, and apparatus. One example mode switching method includes generating, by a first device, first indication information, where a packet data control protocol (PDCP) entity in the first device is connected to at least two radio link control (RLC) entities in a second device, and sending, by the first device, the first indication information to the second device, where the first indication information is used to indicate that transmission between a first RLC entity in the at least two RLC entities and the PDCP entity in the first device is to be canceled. The second device stops the transmission between the first RLC entity and the PDCP entity based on the first indication information.

Abstract: A first access network device obtains voice service indication information and sends a first paging message including the voice service indication information to a first terminal. The first access network device receives, from the first terminal, a request message is usable to request to establish or resume an RRC connection. The request message includes indication information usable to indicate that the RRC connection is established or resumed based on a voice service. The first access network device determines, based on the indication information, to enable the first terminal to access a second access network. The first access network device is located in a first access network using a first radio access technology. The second access network uses a second radio access technology, and the second access network supports the first terminal in performing the voice service to reduce communication delay and improve communication quality.

Abstract: A communication method and apparatus are provided. The method includes: A terminal device sends first data to a network device through a first cell group in an activated state. The terminal device receives a first message from the network device, where the first message is used to deactivate the first cell group. The terminal device changes a state of the first cell group from the activated state to a deactivated state based on the first message of the network device. If the terminal device receives no success acknowledgment of the first data and/or there is second data that has not been transmitted in the first cell group, the terminal device retransmits the first data and/or sends the second data to the network device through a second cell group in an activated state.
