摘要： A secure communication method and a core network node are provided. In the method, a first core network node in a home public land mobile network HPLMN receives a first data authentication request sent by a core network node in a visited public land mobile network VPLMN, and sends a second data authentication request to a home location register HLR or a home subscriber server HSS; the HLR or the HSS generates an end-to-end security key; the first core network node in the HPLMN sends the end-to-end security key to a second core network node in the HPLMN; and the second core network node in the HPLMN performs, based on the end-to-end security key, secure communication with a terminal that has roamed to the VPLMN. This can ensure that a key used in the HPLMN network is not obtained by the VPLMN network.

摘要： This application provides an information transmission method, an apparatus, and a system. The method includes: A sensing network element receives location information of a first area from a first network element. The sensing network element receives first sensing data from a first device, where a sensing area corresponding to the first sensing data includes the first area, and the first device is configured to perform sensing. The sensing network element determines first information based on the location information of the first area and the first sensing data, where the first information indicates that a first terminal device is located in the first area. The sensing network element sends the first information to the first network element. Therefore, whether a terminal device is in the first area may be determined based on sensing data. This reduces signaling overheads.

摘要： This application provides a method for selecting a network element in a communication sensing service and a communication apparatus. In the method, a RAN network element, an AMF network element, and a sensing network element each having a sensing capability can register the sensing capability with an NRF network element. After receiving a sensing service request, an NEF network element, the AMF network element, or the sensing network element selects an appropriate network element based on the sensing capability of each network element (for example, the RAN network element, the AMF network element, or the sensing network element) registered with the NRF network element, to select the appropriate network element for a sensing service, to support the sensing service in an end-to-end manner.

摘要： This application provides a method for providing a communication sensing service. In the method, a first sensing network element in a wireless communication network sends a sensing control request message to a second sensing network element, and controls the second sensing network element to detect and/or collect sensing data. After obtaining the sensing data through detection, the second sensing network element provides the sensing data to the first sensing network element, and the first sensing network element provides a sensing service based on the sensing data, to provide an end-to-end sensing service.

摘要： This application relates to the field of communication technologies, and discloses a communication method and apparatus, to resolve a problem that excessive power is consumed by a receiving terminal device because a transmitting terminal device always sends to-be-sent data during PC5 communication of a V2X service and the receiving terminal device needs to continuously listen to to-be-received data. The method includes: A first terminal device determines a first DRX parameter based on a transmission requirement of a first V2X service, where the transmission requirement includes a service requirement and/or a message pattern; and the first terminal device sends the first DRX parameter to a second terminal device, where the first DRX parameter is used for PC5 communication of the first V2X service between the first terminal device and the second terminal device.

摘要： This application provides a communication method and apparatus, applicable to a 5G system, a V2X system, and the like, to ensure reliability and efficiency of receiving a multicast service by a terminal device in a process in which the terminal device moves from a source access network device to a target access network device. The method includes: The source access network device determines that the target access network device is located within a third sub-service area of a second multicast service to which the source access network device belongs. The source access network device sends forwarding indication information to the target access network device, where the forwarding indication information indicates the target access network device to establish a second forwarding path, and the second forwarding path is used by the source access network device to send third data of the second multicast service to the target access network device.

摘要： This application discloses a deterministic transmission method, a communication apparatus, and a storage medium, and relates to the communication field. In the method, a radio access network device may generate deterministic transmission capability information of a first switching node, and send the deterministic transmission capability information to a first network element. The first switching node includes the radio access network device and a terminal. Then, the radio access network device may receive a first scheduling policy that is delivered by the first network element based on the deterministic transmission capability information of the first switching node, so that deterministic transmission can be performed according to the first scheduling policy. This reduces a delay variation of a QoS flow carrying a TSN flow in a 5GS, and can avoid a need to select a QoS flow whose delay indicator is excessively high for the TSN flow.
