Abstract

A mechanism for notifying a mobile station of receipt of a packet-switched paging message in a GSM communication system. A base station controller (108) sends the packet-switched paging message to the mobile station (116) along a main dedicated control channel in response to the mobile station being capable of operating in a dual transfer mode and being currently engaged in circuit-switch voice interchange activity, resulting in a simultaneous voice and data transmission in dual transfer mode.

wherein said mobile station not having dual transfer capability is a Class C mobile station supporting only non-simultaneous attach on either circuit-switched voice or packet-switched data services.

5. The method of claim 1, wherein said packet-switched paging message is received via SAPI 0 of said dedicated control channel.

6. The method of claim 2, further comprising the step of creating a simultaneous voice and data transmission in dual transfer mode in response to said mobile station being capable of operating in a dual transfer mode and being currently engaged in circuit-switched voice interchange activity.

7. The method of claim 6, wherein the simultaneous voice and data transmission occurs along a channel that includes a one-half traffic channel and a one-half packet data channel.

8. The method of claim 7, wherein the simultaneous voice and data transmission occurs along a channel that includes a full traffic channel and one or more contiguous packet data channels.

9. The method of claim 8, wherein upon being notified of the packet-data, the mobile station is assigned the dedicated control channel as an access channel.

16. The method of claim 2, wherein said mobile station having dual transfer mode capability is a Class A mobile station which supports simultaneous attachment, monitoring, activation, invocation and traffic flow on both circuit-switched voice and packet-switched data services,

wherein said mobile station having dual transfer mode capability is a Class B mobile station which supports simultaneous attachment, monitoring and activation on both circuit-switched voice and packet-switched data services, with invocation and traffic flow possible on either service on a mutually exclusive basis, and

wherein said mobile station not having dual transfer capability is a Class C mobile station supporting only non-simultaneous attach on either circuit-switched voice or packet-switched data services.

10. A method of notifying a mobile station of a packet-switched page, comprising:

determining whether the mobile station is capable of operating in a dual transfer mode;

determining whether the mobile station is currently engaged in circuit-switched voice interchange activity; and

sending a packet-switched paging message on a dedicated control channel if the mobile station is capable of operating in a dual transfer mode and being currently engaged in circuit-switched voice interchange activity.

11. The method of claim 10, wherein the packet-switched paging message is sent via SAPI 0 on said dedicated control channel.

12. The method of claim 11, further comprising the step of creating a simultaneous voice and data transmission in dual transfer mode.

13. The method of claim 12, wherein the simultaneous voice and data transmission occurs along a channel that includes a one-half traffic channel and a one-half packet data channel.

14. The method of claim 12, wherein the simultaneous voice and data transmission occurs along a channel that includes a full traffic channel and one or more contiguous data channels.

15. The method of claim 10, further comprising the steps of:

sending the packet-switched paging message along a dedicated control channel in response to the mobile station being capable of operating in a dual transfer mode; and

sending the packet-switched paging message along the paging channel in response to the mobile station not being currently engaged in circuit-switched voice interchange activity.

17. A method in a portable wireless communication device comprising:

communicating over a traffic channel in a dedicated circuit-switched mode; and

receiving a packet-switched paging message at the device over a dedicated control channel (DCCH) while communicating over said traffic channel.
