Abstract

A method, and associated apparatus, for the selective transmission of packet data to a mobile terminal operable in a radio communication system. When packet data is to be terminated at the mobile terminal, an SMS (short message service) message is first transmitted to the mobile terminal. A determination is made at the mobile terminal whether to permit transmission of packet data thereto. The packet data is transmitted to the mobile terminal if permission is granted by the mobile terminal.

7. The method of claim 6 comprising the additional step of providing the packet data to the SMS-C.

8. The method of claim 7 wherein the cellular communication system further includes a GMSC (gateway mobile switching center) comprising the additional step of forwarding the short message forming the indication of the identity of the sending station to the GMSC.

9. The method of claim 8 comprising the additional step of interrogating the HLR by the GMSC to determine the area at which the mobile station is last-registered to be located.

10. The method of claim 9 wherein the cellular communication station further comprises a serving MSC (mobile switching center) other than the GMSC and wherein the method comprises the additional step of forwarding the short message forming the indication of the identity of the sending station to the serving MSC when the serving MSC is other than the GMSC.

11. The method of claim 1 comprising the additional step of acknowledging detection at the mobile receiving station of detection, during said step of detecting at the mobile receiving station, the indication of the identity of the sending station.

12. The method of claim 11 comprising the additional step, prior to said step of sending the packet data to the mobile receiving station, of registering the mobile receiving station with the network infrastructure if the mobile receiving station is in the standby state.

13. In a radio communication system for communicating packet data between a sending station and a mobile receiving station, the mobile receiving station coupled by way of a radio interface with network infrastructure, the radio interface including a short message channel and a packet channel, and the sending station coupled to the network infrastructure by way of a packet data connection, an improvement of apparatus for selectively permitting transmission of the packet data to the mobile receiving station, said apparatus comprising:
