Abstract: Embodiments of this application provide methods, apparatuses, and systems for physical cell identifier (PCI) conflict detection and optimization. One method includes: receiving a PCI conflict detection notification message for triggering the control network element to perform PCI conflict detection; determining that a PCI conflict exists in at least two cells; determining whether the at least two cells are managed by the control network element; in response to determining that the at least two cells are cells managed by the control network element, performing PCI optimization on PCI conflicted cells managed by the control network element, wherein the PCI conflicted cells comprise the at least two cells; and in response to determining that at least one of the at least two cells is not a cell managed by the control network element, sending a PCI optimization request message to a first management network element, wherein the PCI optimization request message requests the first management network element to perform PCI optimization.

Abstract: Method for latency data obtaining and latency optimization in a data transmission process is provided. The method includes a first device sending a request message to a second device, where the request message is used to obtain latency data of a transmission subpath between the second device and a third device, and a transmission path can be directly established between the third device and the second device; the first device receives a response message sent by the second device, where the response message includes the latency data of the transmission subpath between the second device and the third device; and the first device stores a correspondence between the transmission subpath and the latency data, where the transmission subpath is represented based on a device identifier group including an identifier of the second device and an identifier of the third device. Latency data between devices that can directly establish transmission paths to each other is separately obtained, so that the latency data can be obtained by segment.

Abstract: This application discloses a communication method and a communications apparatus. A first radio network management function network element that can provide a service-based interface is introduced between an access network element and a core network element. In this way, service invocation may be performed with the access network element by invoking a service-based interface of the first radio network management function network element, and service invocation may also be performed with the core network element by invoking a service-based interface of the first radio network management function network element.

Abstract: In a method, a first network element obtains first information of an access network element, and obtains second information, where the first information is used to indicate a resource configuration level of the access network element, and the second information includes one or more of first priority information, second priority information, or third priority information. The first priority information is used to indicate a priority of a terminal device, the second priority information is used to indicate a service priority, and the third priority information is used to indicate a subscriber priority. The first network element determines, based on the first information and the second information, the access network element to provide a service for the terminal device.
