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 invention provide a method for setting an MCPTT group, a device, and a system. A first network device receives a group selection request, where the group selection request is used to instruct to set a first MCPTT group as a selected MCPTT group for a first MCPTT user; and the first network device sends, according to the group selection request, information about the first MCPTT group to first UE used by the first MCPTT user, so that the first network device can set the first MCPTT group as a selected MCPTT group for the first MCPTT user. In this way, a function of setting, by one MCPTT user or a network system, a selected MCPTT group for another MCPTT user is implemented.

Abstract: A communications method and apparatus, where 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, wherein 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 to establish the low-latency service flow, the session management network element flexibly indicates to 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, such that resource utilization and transmission efficiency are improved.
