Abstract

A method for transmitting/receiving paging information in a mobile communication system includes transmitting information through a Broadcast Channel and then receiving paging information through a paging indicator channel based on the indicator transmitted through the Broadcast Channel. The indicator indicates whether or not paging information is transmitted through the paging indicator channel. Reception time point information and reception period information may also be transmitted to assist in receiving the paging information. By transmitting the indicator through the broadcast channel, the mobile terminal is able to save power because it only performs a “wake-up” function when the indicator has a predetermined value indicative of paging information being transmitted through the paging indicator channel.

Claims

1. A method for transmitting/receiving paging information in a mobile communication system, comprising:

transmitting information through a broadcast channel (BCH), said information including an indicator indicating whether or not paging information is transmitted to a mobile communication terminal through a paging indicator channel (PICH); and

receiving, in the mobile communication terminal, the paging information through the PICH based on the indicator received through the BCH.

2. The method of claim 1, wherein the indicator includes a single bit whose value indicates whether or not the paging information is transmitted to the mobile communication terminal through the PICH.

3. The method of claim 2, wherein the indicator is set to a value of ‘

1’

to indicate that the PICH paging information is transmitted, and is set to a value of ‘

0’

to indicate that PICH paging information is not transmitted.

4. The method of claim 2, wherein the indicator being set to ‘

0’

indicates that the PICH is transmitted, and the indicator being set to ‘

1’

indicates that the PICH is not transmitted.

5. The method of claim 1, wherein a UTRAN transmits the indicator through the BCH.

6. The method of claim 1, further comprising:

determining information about a reception time point of the PICH paging information, and transmitting the reception time point information through the BCH in association with the indicator.

7. The method of claim 6, wherein the information about the reception time point includes an offset value with respect to a System Frame Number included in the BCH.

8. The method of claim 1, further comprising

determining information about a reception period of the indicator in the BCH;

and transmitting the reception period information through the BCH in association with the indicator.

9. The method of claim 8, wherein the information about the reception period of the indicator is an offset value with respect to a reception time point of the indicator indicating whether the PICH paging information is transmitted or not.

10. The method of claim 9, wherein the information about the reception period of the indicator is a reception time point of the indicator indicating whether the next PICH paging information is transmitted or not.

11. The method of claim 1, further comprising:

determining information about a reception time point of the PICH paging information and information about a reception period of the indicator in the BCH.

12. The method of claim 1, wherein the transmitting comprises:

setting, by a UTRAN, an indicator in the BCH to indicate whether the PICH paging information is transmitted or not; and

transmitting, by the UTRAN, the BCH including the indicator indicating whether the PICH is transmitted or not to the mobile communication terminal.

13. The method of claim 11, wherein the transmitting comprises:

setting, by a UTRAN, information about a reception time point of the PICH paging information;

setting, by the UTRAN, information about a reception period of the indicator in the BCH; and

transmitting the reception time point information and the reception period information in association with the indicator to the terminal.

14. The method of claim 13, wherein receiving includes:

receiving the PICH paging information based on the reception time point information.

15. The method of claim 14, wherein receiving includes:

recognizing the reception time point of the indicator based on the reception period information.

16. The method of claim 1, wherein the receiving comprises:

checking that the indicator indicating whether the PICH paging information is transmitted is a predetermined value; and

receiving the PICH paging information when the indicator is the predetermined value.

17. The method of claim 16, wherein if the indicator is not the predetermined value, the mobile communication terminal does not receive the PICH paging information.

18. A method for transmitting paging information in a mobile communication system, the method comprising:

setting an indicator to indicate whether paging information is transmitted in a paging indicator channel; and

transmitting the indicator through a broadcast channel to a mobile communication terminal.

19. The method of claim 18, further comprising:

setting information related to a reception time point of the paging information transmitted in the paging indicator channel;

setting information related to a reception period of the indicator; and

transmitting the reception time point information and the reception period information to the mobile communication terminal through the broadcast channel.

20. A method for receiving paging information in a mobile communication system, comprising:

receiving an indicator from a broadcast channel; and

receiving paging information from a paging indicator channel based on the indicator received from the broadcast channel, the indicator indicating whether the paging information was transmitted through the paging indicator channel.

21. The method of claim 20, wherein the paging information is detected as being received through the paging indicator channel is received if the indicator corresponds to a predetermined value.

22. The method of claim 21, wherein the predetermined value is a single-bit value.
