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 (11)

1. A method for paging a wireless terminal comprising:

a) generating a quick page message;

b) generating a full page message, wherein said quick page message contains less data than said full page message;

transmitting said full page message via a first encoded channel and transmitting said quick page message via a second encoded channel, wherein an encoding level of said first encoded channel is more than an encoding level of said second encoded channel 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;

c) calculating said quick paging slot via application of a first hashing function to a MOBILE ID of said wireless terminal;

d) calculating said full paging slot via application of a second hashing function to said MOBILE ID.
2. The method as set forth in claim 1 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.
3. The method as set forth in claim 1 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.
4. The method as set forth in claim 1 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.
5. The method as set forth in claim 1 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.
6. The method as set forth in claim 1 wherein said MOBILE ID is XORed with a function of said system time.
7. The method as set forth in claim 1 wherein said step c) is performed via application of a said first hashing function to system time as well as said MOBILE ID.
8. The method as set forth in claim 1 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.
9. The method as set forth in claim 8 wherein said signal processing circuitry is comprised of a trellis decoding system.
10. The method as set forth in claim 8 wherein said signal processing circuitry is comprised of a deinterleaver.
11. The method as set forth in claim 8 wherein said signal processing circuitry is comprised of a cyclical redundancy check circuit.
