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 With the development of communication technology, the third generation partnership project (3rd generation partnership project,3GPP) defines the environment internet of things (a-IoT). The a-IoT is also referred to as an environmental energy enabled IoT (active power-enabled IoT), or as a passive IoT (P-IoT). The a-IoT may be applied to a variety of traffic scenarios. Such as warehouse/transportation/materials, or fixed asset management, etc. In the a-IoT traffic scenario, a traffic requestor may send a traffic request to a core network to request a corresponding reader to perform a-IoT traffic, such as inventory, read/write, deactivate, etc. However, how to ensure that a-IoT traffic can be performed by the applicable reader is a matter of current research. Disclosure of Invention The embodiment of the application provides a communication method and a communication device, which are used for realizing that business-related operations can be executed by a suitable reader. In order to achieve the above purpose, the application adopts the following technical scheme: In a first aspect, a communication method is provided for a first network element, the method comprising receiving a first message and sending a second message to a first access and mobility management network element. The first message indicates a first service, the second message indicates a first operation, the first operation being related to the first service, the second message further comprises information indicating at least one reader for performing the first service, the at least one reader being connected to the first access and mobility management network element. It is known that, after receiving a request for the first service, such as the first message, the first network element can determine at least one reader capable of executing the first service, and send a second message to the first access and mobility management network element connected to the at least one reader, so as to instruct the at least one reader to execute an operation related to the first service, such as the first operation, that is, to implement the operation capable of being executed by the applicable reader. In a possible design, the method further includes determining the first access and mobility management network element according to the first message, i.e. the first network element may determine the corresponding access and mobility management network element according to the request of the first service, so as to implement the on-demand determination. Optionally, determining the first access and mobility management network element according to the first message includes determining N readers adapted to execute the first service according to the first message, and determining K access and mobility management network elements corresponding to the N readers. N is an integer greater than or equal to 1, N readers include at least one reader, K is an integer greater than or equal to 1, and K access and mobility management network elements include a first access and mobility management network element. That is, the first network can determine, according to the first service, the reader adapted to execute the first service, or all readers capable of executing the first service, and then determine access and mobility management network elements corresponding to the readers, so as to ensure that the information of the first service can be routed to all readers capable of executing the first service through the access and mobility management network elements, respectively, and ensure that the operation corresponding to the first service can be successfully executed. Optionally, the method further comprises the steps of receiving information of M readers from the X access and mobility management network elements, and acquiring corresponding relations between the X access and mobility management network elements and the M readers according to the information of the M readers. X and M are integers greater than or equal to 1, X access and mobility management network elements comprise K access and mobility management network elements, M readers comprise N readers, and the corresponding relation comprises the corresponding relation between the N readers and the K access and mobility management network elements. That is, the first network can dynamically establish the correspondence between the access and mobility management network elements and the readers in advance, so as to ensure that when the readers suitable for executing the operation corresponding to the first service are determined later, the access and mobility management network elements connected with the readers can be found according to the correspondence, so that the subsequent correct data routing is realized. In addition, th
