A session management function entity selection method includes receiving a reselection indication and information about a first session of user equipment UE from a first session management function entity, where the reselection indication is used to instruct to reselect a session management function entity; saving a correspondence between the first session management function entity and the information about the first session according to the reselection indication; receiving a session establishment request message, where the session establishment request message carries the information about the first session; determining a second session management function entity different from the first session management function entity; and sending a session management request to the second session management function entity.

Session management function entity selection method, apparatus, and system

This application discloses a session management function entity selection method, apparatus, and system. The method includes: receiving a reselection indication and information about a first session of user equipment UE from a first session management function entity, where the reselection indication is used to instruct to reselect a session management function entity; saving a correspondence between the first session management function entity and the information about the first session according to the reselection indication; receiving a session establishment request message, where the session establishment request message carries the information about the first session; determining a second session management function entity different from the first session management function entity; and sending a session management request to the second session management function entity. In the foregoing solution, a prior-art problem of selecting an improper session management function entity is resolved.

Embodiments of the present disclosure provide a network slice management apparatus, a service capability exposure function apparatus, and a network slice management method. According to the network slice management apparatus and the service capability exposure function apparatus in the present disclosure, the service capability exposure function apparatus obtains, based on information provided in an application request, information corresponding to a network slice of a core network. The service capability exposure function apparatus further queries an address of a network element in the network slice and communicates with the network element.

Network slice management apparatus and network slice management method

Embodiments of the present disclosure disclose a service processing method, a PCRF, and a system. The method performed by the PCRF includes: obtaining service information of a service, where the service information includes a service identity; obtaining, according to user information and the service information, information indicating that the service requires QoS guarantee, and service chain information; when determining, according to the service chain information, that a network resource occupied by the service may be changed, sending the service identity and the information indicating that the service requires the QoS guarantee to a value-added service processor; receiving target service information, returned by the value-added service processor, of the service corresponding to the service identity; generating a first control policy according to the target service information; and sending the first control policy to a PCEF, so that the PCEF reserves a first network resource according to the first control policy.
