Network-based adaptive streaming media parameter adjustment method and an apparatus

A network-based adaptive streaming media bit rate adjustment method, wherein the method comprises:

• receiving, by a session management network element, media network requirement information from a policy control network element, wherein the media network requirement information comprises at least two bit rate indicators and quality of service (QOS) information corresponding to each of the at least two bit rate indicators, each bit rate indicator indicates a respective bit rate supported by a video server, and the QoS information corresponding to each of the at least two bit rate indicators indicates a network requirement for transmitting streaming media data at a bit rate indicated by a corresponding bit rate indicator;
• and
• sending, by the session management network element, media QoS information to an access network device, wherein the media QoS information comprises the at least two bit rate indicators and QOS requirement information corresponding to each of the at least two bit rate indicators, wherein the at least two bit rate indicators are used for the access network device to determine a target bit rate indicator from the at least two bit rate indicators based on a current network condition and the media QoS information, the current network condition meets a network requirement for transmitting streaming media data at a bit rate indicated by the target bit rate indicator, and, in response to determining, a difference, within a target range, between a network bandwidth detected by the access network device and a target network bandwidth lasts for a target duration, the current network condition is determined to meet a network bandwidth requirement for transmitting the streaming media data at the bit rate.

A network-based adaptive streaming media bit rate adjustment method, wherein the method comprises:

• receiving, by a terminal, a target bit rate indicator from an access network device, wherein a current network condition meets a network requirement for transmitting streaming media data at a bit rate indicated by the target bit rate indicator, the target bit rate indicator is one of at least two bit rate indicators, each of the at least two bit rate indicators indicates a respective bit rate supported by a video server, the at least two bit rate indicators are used for the access network device to determine the target bit rate indicator from the at least two bit rate indicators based on the current network condition and media QoS information, and, in response to determining a difference, within a target range, between a network bandwidth detected by the access network device and a target network bandwidth lasts for a target duration, the current network condition is determined to meet a network bandwidth requirement for transmitting the streaming media data at the bit rate indicated by the target bit rate indicator;
• and
• sending, by the terminal, a streaming media data obtaining request to the video server based on the target bit rate indicator, wherein the streaming media data obtaining request comprises a streaming media data obtaining address corresponding to the target bit rate indicator.
