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: This application provides a communication method and apparatus. The method includes: An EASDF receives an identifier of a target service from a first terminal; the EASDF obtains an address of a same target application server that needs to be accessed by a plurality of terminals including the first terminal to access the target service; and the EASDF sends the address of the target application server to the first terminal. Hence, the EASDF obtains, for a same target service, identifiers (referred to as a UE list) of a plurality of UEs that need to access a same EAS. After UE (for example, UE #1) in the UE list performs an EAS discovery procedure for the target service, the EASDF obtains an address of the target EAS, and sends, to another UE in the list, an address of the target EAS that is the same as an address of the UE #1.

Abstract: The present disclosure provides example traffic routing methods, apparatuses, and systems. One example method includes determining, by a session management network element, a routing rule, where the routing rule indicates a first traffic steering entity to send a first traffic to a first function entity, or send a second traffic to a second function entity or an access device, where the first traffic is a traffic on which first traffic steering control is to be performed, and the second traffic is a traffic on which the first traffic steering control has been performed. The routing rule is sent by the session management network element to the first traffic steering entity in a session management process.

Abstract: This application provides a communication method and apparatus. In the method, each URSP rule included in a URSP corresponds to an HPLMN or a VPLMN of a UE. When the UE accesses an application, based on existing URSP rule matching, the UE uses PLMN information in the URSP rule as one of criteria for the UE to match a URSP rule.

Abstract: This disclosure provides a communication method, and a corresponding apparatus. In the method, a terminal device obtains association information between first traffic description information and second traffic description information; determines the first traffic description information and the second traffic description information; and sends a first request message and a second request message that include same session pair information to establish redundant sessions. The first request message is used to request to establish a first session corresponding to the first traffic description information and the second request message is used to request to establish the second session corresponding to the second traffic description information.

Abstract: This application discloses a path processing method, an apparatus, and a related computer-readable storage medium. In the method, whether there is an existing communication connection for a service flow is determined, and a service feature indicator corresponding to the existing communication connection satisfies a service feature condition required by the service flow. In a case of determining that there is the existing communication connection, a service packet is sent in the existing communication connection. In a case of determining that there is no existing communication connection, a new communication connection is established for the service flow, and a service packet is sent in the new communication connection, and a service feature indicator corresponding to the new communication connection satisfies the service feature condition required by the service flow.
