In some implementation, after the operation that the remote terminal device sends the state information to the network device, the method further includes an operation as follows. The remote terminal device receives a paging message sent by the first access network device based on the state information.
In some implementation, the operation that the remote terminal device receives the paging message sent by the first access network device based on the state information includes an operation as follows. If the state information indicates that the remote terminal device is within the coverage of the network, the remote terminal device monitors an air interface message and receives the paging message sent by the first access network device through the air interface message.
In some implementation, the operation that the remote terminal device receives the paging message sent by the first access network device based on the state information includes an operation as follows. If the state information indicates that the remote terminal device has the subscription relationship and/or the connection relationship with the relay terminal device, the remote terminal device receives the paging message sent by the first access network device through the relay terminal device.
