Description

Communication method and device Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and apparatus. Background The access network device may provide services for an augmented reality (eXtended Reality, XR) service based on at least one of a set (set) of protocol data units (protocol data unit, PDUs), or a data burst (data burst). For example, the access network device may configure discontinuous reception (discontinuous reception, DRX) according to the arrival and end times of the data burst, thereby assisting the terminal device in saving power. Also for example, the access network device may perform packet loss at PDU set granularity, e.g. when the application layer requires that all packets in a certain PDU set are to be transmitted correctly and that part of the packets in the PDU set have been lost, in order to save resources, the access network device may discard the packets of the PDU set. The access network device may acquire PDU set information and/or data burst information before providing the PDU set and/or data burst based service. Currently, after the core network sends a quality of service (quality of service, qoS) parameter of PDU set (may also be referred to as a PDU set QoS parameter) to the access network device, if the core network receives indication information from the access network device, the indication information indicates that the access network device supports PDU set-based processing (PDU set based handling), the core network may send PDU set information and data burst information to the access network device. The application range of the method is narrow, and the method cannot be suitable for more scenes. Disclosure of Invention The application provides a communication method and a communication device, which are used for enabling access network equipment to acquire PDU set information and/or data burst information according to requirements, so that the access network equipment can perform optimization processing according to the PDU set information and/or the data burst information, and the communication performance is improved. In a first aspect, an embodiment of the present application provides a communication method, where the method may be applied to a first access network device or a module in the first access network device. The module in the first access network device may be a communication module in the first access network device, a circuit or a chip responsible for communication functions (such as a modem (modem) chip, also called a baseband (baseband) chip, or a system on chip (SoC) chip or a system in package (SYSTEMIN PACKAGE, SIP) chip, a system on chip or a processor, or may be a logic node, a logic module or software capable of implementing all or part of the functions of the first access network device, for example. The following description will take an example of the application of the method to the first access network device. The method includes that a first access network device determines whether the first access network device needs first information, wherein the first information comprises at least one of partial or all information in PDU set information or partial or all information in data burst information. The first access network device sends first indication information to the first core network device, wherein the first indication information is used for indicating whether the first access network device needs the first information or not. The PDU set information illustratively includes at least one of a PDU set sequence number, a PDU sequence number within a PDU set, a PDU set size, a PDU set importance, or a PDU set end PDU. Illustratively, the data burst information includes at least one of a data burst end identification, a data burst size, or a next burst time. By the method, the first access network device can send the first indication information to the first core network device so as to inform the first core network device whether the first access network device needs part or all of PDU set information and/or data burst information. Therefore, the first access network device can acquire the PDU set information and/or the data burst information as required, so that the first access network device can perform optimization processing, such as scheduling optimization, according to the PDU set information and/or the data burst information, and the communication performance is improved. In addition, in the method, the operation of the first access network device for sending the first indication information does not depend on whether the first access network device acquires the QoS parameter of the PDU set or not and does not depend on whether the first access network device supports processing based on the PDU set, so that the first access network device can flexibly acquire part or all of the PDU set information and/or the data burst information, the appli
