A method, an apparatus, and a system for capability negotiation, and a storage medium, and relates to the communication field. The method includes: a first network entity obtains a capability update message, where the capability update message includes capability update information, and the capability update information indicates at least one capability to be updated of the first network entity. The first network entity sends the capability update message to the second network entity based on a capability negotiation session established between the first network entity and a second network entity. The embodiments can simplify a process of capability negotiation, thereby improving efficiency of capability negotiation, achieving dynamic negotiation of a capability, and reducing load of a PCC and a PCE.

Method, apparatus, and system for dynamic capability negotiation for improving the efficiency of capability negotiation process

A service processing method includes that a first network device determines a second network device on a forwarding path of a packet based on a service requirement; the first network device sends a first message to the second network device, to establish a first connection to the second network device; and the first network device sends a second message to the second network device using the first connection, where the second message requests the second network device to assist in determining information related to the forwarding path. when determining the second network device is needed to assist the first network device for information related to the forwarding path of the packet, the first network device actively establishes a connection to the second network device, and requests, using the established connection, the second network device to assist the first network device in determining the information related to the forwarding path.
