Abstract: A method includes: receiving session management information from a session management network element in a first network, where the session management information is used to request to establish a user plane tunnel of a voice service of a terminal device in the first network; and sending a handover request to a mobility management network element in the first network based on the session management information to indicate a handover of the terminal device from the first network to a second network that supports a circuit switched domain voice service. When the access network device in the first network receives the session management information to request to establish the user plane tunnel, the handover request is sent to the mobility management network element in the first network based on the session management information to establish a circuit switched domain voice service of the terminal device in the second network.

Abstract: This application provides a parameter determining method and a communications entity. The method includes: When a UE is in a system in which an evolved packet system (EPS) network and a 5GS network interwork, the UE is currently located in the 5GS network, and QoS parameters used include an authorized UE aggregate maximum bit rate (AMBR) and an authorized session AMBR of a session. Because of movement of the UE, the UE needs to be handed over to the EPS network, and QoS parameters that need to be used for the UE in the EPS network include an authorized UE AMBR and an authorized access point name (APN) AMBR. The authorized APN AMBR is determined by a first communications entity based on at least one of a subscribed APN AMBR or the authorized session AMBR of the PDU session, and the authorized UE AMBR is determined by a second communications entity based on the authorized APN AMBR.
