Abstract: This application provides methods, devices, and systems. In an example method performed by a session management network element, the session management network element receives a first policy and charging control (PCC) rule from a policy control network element, wherein the first PCC rule comprises indication information, and the indication information indicates that a service corresponding to the first PCC rule is a time sensitive service. The session management network element binds the first PCC rule to a quality of service (QoS) flow, wherein no other PCC rule is bound to the QoS flow.

Abstract: A packet delay parameter obtaining method, apparatus, and system are provided. The method provides a session management network element determines whether a first QoS flow satisfying a parameter condition exists, where the first parameter indicates information corresponding to a PSA UPF transmitting the first QoS flow, the first parameter indicating information corresponding to a PSA UPF transmitting the first service flow. If no first QoS flow satisfying the parameter condition exists, a second QoS flow for the first service flow is established, and the session management network element sends a first message to an access network element, the first message including identification information of the second QoS flow and a packet delay parameter corresponding to the second QoS flow.

Abstract: In a method for configuring a policy for user equipment (UE), a PCF network element receives policy information of the UE from a first network element. The policy information of the UE indicates a current policy of the UE. The PCF network element sends configuration information to the UE based on the policy information of the UE, and the configuration information instructs the UE to update the policy of the UE. The policy control function network apparatus then sends to the first network apparatus update information that comprises either the configuration information or an identifier of the configuration information.

Abstract: Embodiments of the present invention relate to a method and an apparatus for presenting an indoor traffic map. The method includes: sending, by a near-end unit of an indoor distribution system, a pseudo carrier to a polled remote unit according to a pre-established polling routing table; receiving operating data collected by the remote unit and a measurement report reported by the terminal; determining traffic map data of the polled remote unit; determining whether the traffic map data meets a traffic map presenting condition, and presenting an indoor traffic map when the traffic map presenting condition is met. In the present invention, remote units are polled sequentially by using a pseudo carrier and a polling routing table, operating data of the remote unit and a measurement report of the terminal are obtained as traffic map data, to perform representation of a traffic map.

Abstract: Example methods, devices, and apparatuses are discussed. An example method includes determining that a condition associated with triggering a registration procedure is satisfied. The condition comprises that a second tracking area (TA) supports a first slice. The second TA belongs to a current registration area (RA) of the terminal device. The first slice is rejected in the current RA, wherein the terminal device is in the second TA. The example method further includes,n response to the determination, sending a second registration request message to a core network device. The second registration request message requests to access the first slice. The second registration request message comprises information about the first slice.
