Abstract: A communication method and device determines information of a data packet that fails to be transmitted in a first QoS flow. Some or all of the data packet that fails to be transmitted is discarded, and a sequence number is reset for an unsent data packet, so that the sequence number of the unsent data packet and a sequence number of a successfully sent data packet are consecutive. If the first QoS flow includes a data packet that fails to be transmitted, some or all of the data packet may be discarded. This is equivalent to skipping retransmitting a discarded data packet.

Abstract: A wireless communication method is applied to a communications system including a UE, a RAN, a first core network entity, and at least one network slice. The wireless communication method includes: establishing, by the first core network entity, a signaling connection to the UE; receiving, by the first core network entity and from the UE via the signaling connection, network slice information and a non-access stratum NAS message; determining, by the first core network entity and based on the network slice information, a target network slice from the at least one network slice, where the target network slice includes a second core network entity, and the UE performs NAS communication with the second core network entity using the RAN and the first core network entity; and sending, by the first core network entity, the NAS message to the second core network entity.

Abstract: A circuit switched fallback (CSFB) method and apparatus, where a user equipment (UE) initiates a calling process, receives a first request from a first communications system, and after the UE is transferred to a second communications system and before the UE receives a first message from the second communications system, the UE determines that a voice call bearer cannot be set up in the second communications system, and initiates a CSFB in the second communications system, where the first message is used by the UE to determine that a call request has failed.

Abstract: A data transmission method includes obtaining a user equipment route selection policy (USRP) rule parameter of a started application, establishing a first protocol data unit (PDU) session corresponding to the started application with a network device through the modem module when no PDU session parameter matching the URSP rule parameter exists in the mapping table, adding an interface name of the first PDU session to the routing table adding a mapping relationship between the session parameter of the first PDU session and the interface name of the first PDU session to the mapping table, and routing to-be-transmitted data of the started application to the first PDU session by using the interface name of the first PDU session.

Abstract: Methods, systems, and apparatus for call prompting when a call initiated by a terminal is unconnected during a call between two other terminals. In one example method, a first interface, indicating that the first terminal is in a call with a second terminal, is displayed on the first terminal. If a third terminal initiates a call to the first terminal, a second interface, indicating the call initiated by the third terminal, is displayed on the first terminal, and a sound, which includes a call voice and a prompt tone of the initiated call, is output. If the third terminal's initiated call is rejected, the call voice is output on the first terminal, and the prompt tone stops being output. If the third terminal stops initiating the call, the first interface is displayed on the first terminal, and the call voice between the first terminal and the terminal continues being output.

Abstract: The present disclosure describes methods, devices, and systems for signal strength measurement. An example method includes: broadcasting, by a first relay device, a first message, wherein the first message is used by a first remote device to discover the first relay device; establishing, by the first relay device, a connection to the first remote device; and sending, by the first relay device, a second message, wherein the second message is used by the first remote device to measure signal strength of a link between the first remote device and the first relay device.

Abstract: Embodiments provide a core network selection method, an apparatus, and a system. The method includes the following steps: obtaining first dedicated core network (DCN) information from an access network device, where the first DCN information includes information about at least one DCN that can be accessed by the access network device. The method also includes selecting a to-be-accessed DCN from the at least one DCN according to the first DCN information, and sending information about the to-be-accessed DCN to the access network device, so that the access network device determines a core network device according to the information about the to-be-accessed DCN.
