Abstract: This application provides a QoS flow control method and an apparatus. An SMF network element receives first indication information sent by an access network apparatus, where the first indication information is used to indicate that a first QoS target of a QoS flow cannot be met; and the SMF network element does not process the QoS flow if the SMF network element receives second indication information in a first preset time; or the SMF network element deletes or modifies the QoS flow if the SMF network element does not receive second indication information in a first preset time, where the second indication information is used to indicate that the first QoS target can be met.

Abstract: Embodiments of the present application relate to the wireless communications field, and in particular, to a session management method and a session management network element. The session management method includes: receiving, by a first control plane network element, a user equipment UE context response message from a second control plane network element, where the UE context response message carries a first session message, and the first session message is a pending session message; and sending, by the first control plane network element, a second session message to user equipment according to the UE context response message. According to the session management method and the session management network element in the embodiments of the present application, a session can be managed in a scenario in which a control plane connection of user equipment changes.

Abstract: This application discloses a communications method and apparatus. The method includes: sending, by a session management network element, first indication information when the session management network element determines, based on first information, to establish a first low-latency service flow for a session; and the first indication information is used to indicate to set the session to an always-on session. According to solutions of this application, when determining, based on the local configuration information, the subscription data, and the QoS parameter, to establish the low-latency service flow, the session management network element flexibly indicates a terminal apparatus to set the session to the always-on session. This avoids a resource waste caused by setting the session to the always-on session all the time, and avoids a transmission latency caused when the session is not set to the always-on session in time, so that resource utilization and transmission efficiency are improved.

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.
