Abstract

A method of and apparatus for paging a wireless terminal in a wireless telecommunications system reduce standby mode power consumption. A minimally encoded quick paging channel is established over which short, quick page messages (30) are transmitted during one of a set of quick paging slots. The quick page message indicates that a communications request has been received, and that the receiving communication terminals should process a highly encoded full paging channel over which more detailed, full page messages (32) are transmitted during the next full paging slot. A terminal monitors full paging channel only after a quick page message has been received on the quick paging channel.

Claims (32)

1. A method for paging a wireless terminal in a wireless telecommunications system comprising:
transmitting a quick page message via a less encoded channel; and generating a full page message via a more encoded channel.
2. The method as set forth in claim 1 wherein said quick page message contains less information than said full page message.
3. The method as set forth in claim 1 or 2 wherein said quick page message is for notifying the wireless terminal to begin processing for said full page message.
4. The method as set forth in claim 1, 2 or 3 wherein said quick page message is comprised of a single bit of data.
5. A method for paging a wireless terminal from a set of wireless terminals comprising:
a) transmitting a quick page message directed to a subset of said set of wireless terminals that includes the wireless terminal; and b) generating a full page message identifying said wireless terminal.
6. The method as set forth in claim 5 wherein step a) is comprised of the step of transmitting said quick page message via a less encoded channel during a time slot assigned to the wireless terminal.
7. The method as set forth in claim 6 wherein step b) is comprised of the step of transmitted said full page message during a second time slot assigned to the wireless terminal that occurs after said first time slot.
8. The method as set forth in claim 5, 6 or 7 wherein said quick page message is transmitted over said less encoded channel and said full page message is transmitted over a more encoded channel.
9. The method as set forth in claims 8 wherein said first channel is established via direct sequence modulation with a first channel code, and said second channel is established via direct sequence modulation with a second channel code.
10. The method as set forth in claim 9 wherein said first channel code is a first Walsh code and said second channel code is a second Walsh code.
11. The method as set forth in any of claims 5 to 10 wherein said quick page message has less information than said full page message.
12. A method for paging a wireless terminal comprising:
a) generating a quick page message; and b) generating a full page message, wherein said quick page message contains substantially less data than said full page message.
13. The method as set forth in claim 12 wherein said quick page message is transmitted on less encoded channel, and said full page message is transmitted on a more encoded channel.
14. The method as set forth in claim 12 or 13 further comprising the steps of:
convolutionally encoding said full page message;
direct sequence spreading said full page message; and direct sequence spreading said quick page message.
15. The method as set forth in claim 12, 13 or 14 further comprising the steps of:
adding error detection information to said full page message;
direct sequence spreading said full page message; and direct sequence spreading said quick page message.
16. The method as set forth in claim 12, 13 or 14 further comprising the steps of:
interleaving said full page message;
direct sequence spreading said full page message; and direct sequence spreading said quick page message.
17. The method as set forth in any of claims 12 to 16 further comprising the steps of adding a time delay between when said quick page message is transmitted and when said full page message is transmitted. '
18. The method as set forth in any of claims 12 to 17 further comprising the steps of:
receiving said quick page message;
activating signal processing circuitry; and processing a full paging channel using said signal processing circuitry.
19. The method as set forth in claim 18 wherein said signal processing circuitry is comprised of a trellis decoding system.
20. The method as set forth in claim 18 or 19 wherein said signal processing circuitry is comprised of a deinterleaver.
21. The method as set forth in claim 18, 19 or 20 wherein said signal processing circuitry is comprised of a cyclical redundancy check circuit.
22. The method as set forth in any of claims 12 to 21 wherein said quick page message is transmitted during a quick paging slot within a paging channel, and said full page message is transmitted during a full paging slot within said paging channel.
23. The method as set forth in any of claims 12 to 22 further comprising the steps of:
c) calculating a quick paging slot via application of a first hashing function to a MOBILE ID of said wireless terminal;
d) calculating a full paging slot via application of a second hashing function to said MOBILE ID, wherein said quick page message is transmitted during said quick paging slot and said full page message is transmitted during said full paging slot.
24. The method as set forth in claim 23 wherein said MOBILE ID is XORed with a function of said system time.
25. The method as set forth in claim 23 or 24 wherein said step c) is performed via application of a said first hashing function to system time as well as said MOBILE ID.
26. A method of receiving a paging message comprising the steps of:
a) monitoring a quick paging channel for a quick page message;
and b) monitoring a full paging channel when a quick page message is received.
27. The method as set forth in claim 26 wherein said quick paging message is shorter is duration than said full page message.
28. The method as set forth in claim 26 or 27 wherein said quick paging channel is less encoded than said full paging channel.
29. The method as set forth in claim 26, 27 or 28 wherein said full paging channel is processed by modulation with a first channel code, and said quick paging channel is processed by modulation with a second channel code.
30. The method as set forth in claim 29 wherein said quick page message is monitored for on a paging channel during a quick paging slot, and said full page message is monitored for on said paging channel during a full paging slot.
31. The method as set forth in any of claims 26 to 30 further comprising the steps of:
activating signal processing circuitry when a quick page message is received, wherein step b) is performed using said signal processing circuitry.
32. An apparatus for paging a wireless terminal in a wireless telecommunications system, the apparatus comprising:
means for transmitting a quick page message via a less encoded channel; and means for generating a full page message via a more encoded channel.
