Abstract

A method of status enquiry between a plurality of subscriber communication units in a wireless communication system includes the step of transmitting (220) a status enquiry message from a first subscriber communication unit (100) to a second subscriber communication unit. The second subscriber communication unit receives said status enquiry message and transmits (240) a status response message back to said first subscriber communication unit in response to said status enquiry message. This provides an ability to a subscriber unit to determine the status of another subscriber unit without the need to initiate a full call set-up to that subscriber unit. This allows the user to automatically ascertain whether the destination subscriber unit is available before making the call. The destination subscriber unit may automatically respond without user input, and preferably without the need for the user to be informed.

Claims

1. A method of status enquiry between a plurality of subscriber communication units in a wireless communication system, the method comprising the steps of:

transmitting a status enquiry from a first subscriber communication unit to a second subscriber communication unit;

receiving said status enquiry at said second subscriber communication unit; and

transmitting a status response message back to said first subscriber communication unit in response to said status enquiry.

2. The method of status enquiry according to claim 1, wherein the step of transmitting a status response message is performed either automatically or in response to a second subscriber communication user input.

3. The method of status enquiry according to claim 1, the method further comprising the step of:

displaying at said first subscriber communication unit, upon receipt of the status response message, a status indication of said second subscriber communication unit.

4. The method of status enquiry according to claim 1, the method further comprising the step of:

displaying at said second subscriber communication unit, upon receipt of said status enquiry message, an indication that a status enquiry message has been received.

5. The method of status enquiry according to claim 1, the method further comprising the steps of:

transmitting said status enquiry message from said first subscriber communication unit via infrastructure in said wireless communication system to said second subscriber communication unit; and

/or

transmitting said status response message from said second subscriber communication unit via infrastructure in said wireless communication system to said first subscriber communication unit.

6. The method of status enquiry according to claim 1, the method further comprising the step of:

providing a user of said second subscriber communication unit with an ability to input status information to be included in a response to a status enquiry message.

7. The method of status enquiry according to claim 1, wherein said status enquiry message is transmitted in the form of a short message service message.

8. The method of status enquiry according to claim 7, the method further comprising the step of:

identifying said status enquiry message as being a status enquiry in a header portion of said short message service message.

9. The method of status enquiry according to claim 1, the method further comprising the step of:

making a number of features of said status enquiry message or said status response message user-configurable.

10. The method of status enquiry according to claim 9, wherein said user-configurable features include at least one of:

(i) an ability to transmit or receive status enquiry calls at a particular time of a day, or a particular day in a week,

(ii) whether a status enquiry message and/or a status enquiry response should be displayed to a user,

(iii) whether a subscriber communication unit is accepting calls,

(iv) whether a subscriber communication unit is accepting priority calls,

(v) when a subscriber communication unit will start accepting calls,

(vi) whether a subscriber communication unit is arranged to play, for example, a ring tone on receiving a call, or

(vii) whether a subscriber communication unit is muted.

11. The method of status enquiry according to claim 1, the method further comprising the step of:

storing said status enquiry message and/or said status response message in either an element in the infrastructure of said wireless communication system for subsequent re-transmittal to a requesting or destination subscriber unit or in said first or second subscriber communication unit for subsequent retrieval by a user.

12. The method of status enquiry according to claim 1, the method further comprising the step of:

tagging at least one phonebook entry or call register relating to said status enquiry message such that it can be transmitted at a time of a day, or periodically, to allow a user to be kept informed as to the availability of at least one other subscriber communication unit.

13. A wireless communication system adapted to facilitate the status enquiry method steps of claim 1.

14. A subscriber communication unit adapted to perform any of the method steps of claim 1.

26. A storage medium storing processor-implementable instructions for controlling a processor to carry out the method of claim 1.

15. A subscriber communication unit comprising:

a controller for controlling transmission or reception of a status enquiry message or a status response message; and

a transmitter circuit, operably coupled to said controller, transmitting a status enquiry message or a status response message to another wireless remote communication unit.

16. A subscriber communication unit according to claim 15, the subscriber communication unit further comprising:

a controller for controlling transmission or reception of a status enquiry message or a status response message; and

a receiver circuit, operably coupled to said controller, receiving said status enquiry message or a status response message from another wireless remote communication unit.

17. The subscriber communication unit according to claim 15, the subscriber communication unit further comprising:

a memory device storing status information relating to at least one other subscriber communication unit.

18. The subscriber communication unit according to claim 17, wherein the memory device stores a phone book feature or call register feature related to said or at least one other subscriber communication unit that a user of said subscriber communication unit may access.

19. The subscriber communication unit according to claim 17, wherein the memory device stores a list of options in a menu accessible from said memory device, wherein said list of options includes a status enquiry option to initiate said status enquiry message.

20. The subscriber communication unit according to claim 15, wherein the subscriber communication unit is one of:

a cellular phone, a portable or mobile radio, a personal digital assistant or a laptop computer.

21. A subscriber communication unit, comprising:

a controller for controlling transmission or reception of a status enquiry message or a status response message; and

a receiver circuit, operably coupled to said controller, receiving said status enquiry message or a status response message from another wireless remote communication unit.

22. he subscriber communication unit according to claim 21, the subscriber communication unit further comprising:

a memory device storing status information relating to at least one other subscriber communication unit.

23. The subscriber communication unit according to claim 22, wherein the memory device stores a phone book feature or call register feature related to said or at least one other subscriber communication unit that a user of said subscriber communication unit may access.

24. The subscriber communication unit according to claim 22, wherein the memory device stores a list of options in a menu accessible from said memory device, wherein said list of options includes a status enquiry option to initiate said status enquiry message.

25. The subscriber communication unit according to claim 21, wherein the subscriber communication unit is one of:

a cellular phone, a portable or mobile radio, a personal digital assistant or a laptop computer.
