Description

Communication method and device Technical Field The present application relates to the field of communications, and in particular, to a communication method and apparatus. Background The environment internet of things (ambient internet of things, a-IoT) device is a low-power-consumption and low-complexity internet of things terminal device, and the a-IoT device performs random access with a reader-writer by receiving and responding to a paging message sent by the reader-writer to perform device-to-reader (D2R) data transmission and/or reader-to-device (D2R) data transmission, or performs D2R data transmission and D2R data transmission directly with the reader-writer. Wherein the paging message includes the requested service identification (e.g., session ID). Currently, in order to prevent the failure of the a-IoT device to receive the paging message, a paging retransmission scheme is introduced, that is, the same reader/writer may repeatedly send the paging message including the same session ID to the same a-IoT device, but in order to prevent the a-IoT device from repeatedly responding to multiple paging messages of the same service sent by the service request based on the core network, for example, the a-IoT device repeatedly performs random access due to repeated response, and after the a-IoT device responds to one paging message including the session ID and completes a service, the a-IoT device does not respond to receiving the paging message including the same session ID again. However, the response manner of the a-IoT device described above cannot be applied in some services or application scenarios that need to repeatedly respond to the paging message of the same service, such as a neighboring location service, or a pipeline scenario. Disclosure of Invention The application provides a communication method and a communication device, which can realize that an A-IoT device can determine whether to repeatedly respond to paging messages of the same service sent by the same reader-writer or different reader-writers, and flexibly adapt to the requirements of different services or application scenes. In order to achieve the above purpose, the application adopts the following technical scheme: In a first aspect, a communication method is provided, which may be performed by a first access device, or a component of the first access device, for example, a processor, a chip, or a system-on-chip of the first access device, or a logic module or software capable of implementing all or part of the first access device. Taking the first access device or the chip in the first access device as an example, the method comprises the steps of sending a first message, wherein the first message is associated with a first identifier, the first identifier is used for identifying first service, and the first message comprises a second identifier. The method includes communicating with a first device, the first device being a device that responds to a first message. In this aspect, the first access device may carry a second identity in the first message associated with the first service, the second identity being a different identity to the first identity identifying the first service, the second identity being available to the first apparatus to determine whether to respond to the first message. Therefore, under the condition that a plurality of access devices respectively send messages related to the same service, different access devices can determine different identifiers (or different second identifiers) with similar functions to the second identifiers, and any two access devices determine different identifiers with similar functions to the second identifiers, or under the condition that one access device sends a plurality of messages related to the same service, the access devices can also determine different identifiers with similar functions to the second identifiers and respectively bear a plurality of messages related to the same service, so that a first device can determine whether to respond to the messages related to the same service, such as paging messages, sent by the same access device or different access devices according to the second identifiers, and the requirements of different services or application scenes can be flexibly met. In one possible design, the communication method may further include receiving a first identifier and first indication information, where the first indication information is used to indicate that a first message and a second message need to be responded by the first device, the first message is a message related to a first service sent by the first access device, and the second message is a message related to the first service sent by the second access device. Thus, the first access device may receive the first identifier and the first indication information sent from the core network element or other access devices, so that the second identifier may be determined, so that the first
