Abstract: A session management network element receives first information from a first anchor user plane network element anchored by a first session established by a first terminal device, where the first information includes address information of data transmitted between the first terminal device and a second terminal device. The session management network element determines, based on the first information, whether the first terminal device and the second terminal device use a same access network or a same backhaul network. The session management network element determines, when the first terminal device and the second terminal device use the same access network or the same backhaul network, a first network element configured to forward data of the first session.

Abstract: Embodiments of this application provide a positioning method and apparatus. The method includes: A first device receives, in a first system, a first trigger message for starting a positioning procedure. If the first device detects a first event, and the first device access a second system or moves to the second system, the first device sends a first message applicable to the second system. In addition, the first message includes location quality of service (QoS) applicable to the second system. According to this method, a device in the second system can recognize the first message and first location QoS, so that the device in the second system can continue a location service, to maintain continuity of the location service.

Abstract: This application provides a communication method and an apparatus. The communication method includes: A terminal device in a satellite service range receives first indication information indicating the terminal device to notify a network when the terminal device is in an idle state or a suspended state and is about to leave the satellite service range. The terminal device in the idle state or the suspended state determines that the terminal device is about to leave the satellite service range, and in this case, reports second indication information indicating that the terminal device is about to leave the satellite service range. In this way, a network side learns whether the terminal device in the idle state or the suspended state has left the satellite service range, thereby avoiding invalid paging.
