    Abstract: This application relates to the field of communications technologies, and in particular, to an auxiliary-link-based call compensation system and apparatus, and chip. The system includes: a first terminal, a second terminal, and a core network device. The first terminal and the second terminal establish a primary link in response to a dialing operation entered by a user. The first terminal and the second terminal establish at least one auxiliary link in response to an auxiliary link establishment condition. The first terminal transmits call data packets with the second terminal by using the primary link and the at least one auxiliary link. The first terminal and/or the second terminal performs post-processing and playing on the call data packets received by using the primary link and the at least one auxiliary link.

    IPC: H04M7/00

    Abstract: This application discloses a call method and system, and a related apparatus. When a specific condition is met (for example, a callee fails to be paged), a network device forwards, to a VoIP server, a first call request to a target number, where the first call request is a call request initiated by a calling terminal to the target number, and the target number has been subscribed to a call forwarding service. Then the VoIP server parses a forwarding message from the network device to obtain a called number, searches, based on the called number, for the called terminal associated with the called number, and initiates a VoIP call to the called terminal, so that the callee in an out-of-service state (for example, there is no signal of an operator network or the callee is in an airplane mode) can still receive the call request from the caller.

    Abstract: A cell selection method, related to the communications field, includes a terminal device sending a first request to a network device, where the first request is used to request to select a serving cell for the terminal device in an energy efficiency first manner. The terminal device sends first information to the network device, where the first information is used by the network device to select a cell in a first communications system or a cell in a second communications system for the terminal device. The terminal device receives configuration information of a serving cell from the network device, where the serving cell is selected by the network device from the cell in the first communications system or the cell in the second communications system in a manner that energy efficiency of the terminal device is first.
