Abstract: A communication method and apparatus are provided to improve a power saving effect of the terminal device and service experience. After obtaining traffic characteristic information of a service, an access network device determines power saving configuration information based on the traffic characteristic information, and then sends the power saving configuration information to the terminal device. The power saving configuration information is used to determine that the terminal device is in an active state or a sleep state when the service is performed. In this way, the access network device can sense the traffic characteristic information of the service, to determine the power saving configuration information matching the service, and to improve the power saving effect of the terminal device and the service experience.

Abstract: Example network-based adaptive streaming media parameter adjustment methods and apparatuses are disclosed. One example method includes receiving, by an access network device, media QoS information from a session management network element, where the media QoS information includes at least two bit rate indicators and QoS requirement information corresponding to each of the bit rate indicators. The access network device determines, based on a current network condition and the media QoS information, a target bit rate indicator from the at least two bit rate indicators. The target bit rate indicator is sent to a terminal or a video server, where the current network condition meets a network requirement for transmitting streaming media data at a bit rate indicated by the target bit rate indicator.

Abstract: A transmission method and a communication apparatus provide a source access network device receives first data and a first identifier. The first identifier indicates a last data packet of the first data, and the first data is data in a first periodicity of a periodic service. The source access network device sends a handover command to a terminal device in a first time period. A start moment of the first time period is a moment at which the last data packet is sent, an end moment of the first time period is an end moment of the first periodicity, and the handover command instructs the terminal device to perform a handover to a target access network device. This avoids interruption of sending the first data by the source access network device due to the handover and improves transmission reliability of the periodic service.

Abstract: This application provides a method and an apparatus for determining an air interface latency and relates to the field of communications technologies. In the method, an access network device obtains an air interface latency of a downlink data packet and schedules the downlink data packet based on the air interface latency of the downlink data packet. The air interface latency of the downlink data packet is calculated based on a round-trip latency, and the round-trip latency is a latency from when a terminal sends an uplink data packet to when the terminal receives the downlink data packet corresponding to the uplink data packet. In the method, the access network device may schedule the downlink data packet based on the air interface latency of the downlink data packet, so as to precisely control a latency in uplink and downlink data transmission.
