As an optional embodiment, the paging manner includes paging through an air interface message or paging through a relay terminal device having the subscription relationship and/or the connection relationship with the remote terminal device.

As an optional embodiment, the determination module 420 is configured to, if the state information indicates that the remote terminal device is within the coverage of the network, determine that the paging manner for the remote terminal device is the paging through the air interface message.

As an optional embodiment, the determination module 420 is further configured to, if the state information indicates that the remote terminal device has the subscription relationship and/or the connection relationship with the relay terminal device, determine that the paging manner for the remote terminal device is the paging through the relay terminal device.

As an optional embodiment, the determination module 420 is further configured to, if the state information indicates that the remote terminal device has the subscription relationship and/or the connection relationship with the relay terminal device and the remote terminal device is within the coverage of the network, determine that the paging manner for the remote terminal device is the paging through the relay terminal device.

As an optional embodiment, the determination module 420 is further configured to, if the state information indicates that the remote terminal device has no subscription relationship and/or connection relationship with the relay terminal device and the remote terminal device is out of the coverage of the network, determine that the paging manner for the remote terminal device is the paging through the relay terminal device.
