Abstract: Embodiments of the present invention disclose a method, a related apparatus, and a system for recovering a called service of a terminal. The method includes: when a called request of a user terminal is received, querying an initial proxy-call session control function (P-CSCF) entity with which the user terminal currently registers; if it is detected that the initial P-CSCF is faulty, selecting an available P-CSCF and sending, to the available P-CSCF, a notification message that carries a redundancy identifier, where the redundancy identifier is used to instruct the available P-CSCF to trigger the user terminal to re-register with the P-CSCF; and when a registration complete message sent by the P-CSCF with which the user terminal re-registers is received, delivering the called request to the re-registered P-CSCF to bear a called service of the user terminal.

Abstract: This application provides a call processing system, a call processing method, and a communications apparatus. The system includes a call processing device and an event manager. The call processing device is configured to perform a connection and routing processing for a call initiated by calling user equipment, and is further configured to perform event detection for the call to obtain a detected event set, and report the detected event set to the event manager. The detected event set requests to trigger an update processing for the call. The event manager is configured to manage the update processing for the call based on the detected event set reported by the call processing device.

Abstract: A video transmission method includes: A first media gateway receives an uplink media packet sent by a first terminal, where the uplink media packet carries information indicating that the first terminal supports an uplink-downlink resolution asymmetry capability and an uplink media stream of a first resolution of the first terminal. The first media gateway sends a first downlink media packet to the first terminal, where the first downlink media packet carries a downlink media stream of a second resolution of the first terminal, and the first resolution is different from the second resolution. The solution is applicable to the following case: In a video call process, a terminal that supports different resolutions in a sending direction and a receiving direction can lower a resolution based on channel quality to deliver a video packet, and can raise a resolution when network resources are sufficient.

Abstract: A cell handover method is disclosed. A terminal obtains a signal attenuation observation instruction, detects, in response to the signal attenuation observation instruction, signal strength and a signal attenuation parameter of a first cell, and sends the signal strength and the signal attenuation parameter to a network side device. Then, the network side device determines, based on the signal strength and the signal attenuation parameter, whether a cell handover is to be performed by the terminal. After performing a cell handover for the terminal is determined, the terminal is triggered to perform the cell handover from the first cell to a second cell. The first cell is a serving cell of the terminal, and the second cell is a neighboring cell of the first cell.
