Abstract

In a wireless mobile communications system, a method for processing paging information allows the operations of a mobile terminal to be simplified and permits efficient use of resources for the mobile terminal. The network instructs in advance, the transmission of control information, such as a particular paging message, a notification message, system information and the like, via a single indicator channel. The mobile terminal receives this single indicator channel and uses the indicator information that was transmitted via the indicator channel in order to receive the control information.

Claims

1. A method of reception of paging information for a mobile terminal in a mobile communications system, the method comprising:

receiving control information in a periodic manner;

if the received control information is relevant to the mobile terminal, receiving paging information using scheduling information that indicates time and frequency information of the paging information.

2. The method of claim 1, wherein the control information includes either a mobile terminal identifier or a service identifier, or an indicator that indicates a mobile terminal identifier or service identifier.

3. The method of claim 1, wherein the received control information and paging information are in the same sub-frame.

4. The method of claim 1, further comprising:

receiving primary system information in a static manner, the primary system information containing the scheduling information that is used for receiving the paging information; and

receiving non-primary system information in a dynamic manner, the non-primary information containing the control information.

5. The method of claim 4, wherein the scheduling information indicates at least one of a time characteristic and a frequency characteristic of the non-primary system information.

6. The method of claim 5, wherein the time characteristic and the frequency characteristic indicate a location of the non-primary system information to be read by the particular terminal.

7. The method of claim 6, wherein the primary system information further comprises an indicator for indicating a particular terminal.

8. The method of claim 7, wherein the indicator comprises:

at least one of a terminal identifier, a service identifier, and a logical channel identifier.

9. The method of claim 5, wherein the time characteristic relates to symbols and the frequency characteristic relates to sub-carriers.

10. The method of claim 1, wherein the paging information is in the form of at least one resource block.

11. The method of claim 1, wherein the control information related to paging and notification, and other resource blocks are received via a center frequency among broadband frequencies used for a system bandwidth.

12. The method of claim 11, wherein the control information is for a mobile terminal in idle mode.

13. A method of downlink transmission of paging information for a mobile terminal in a mobile communications system, the method comprising:

transmitting control information in a dynamic manner to a group of cells,

wherein the control information comprises scheduling information that indicates time and frequency information; and

transmitting paging information according to the control information.

14. The method of claim 13, wherein the control information includes either a mobile terminal identifier or a service identifier, or an indicator that indicates a mobile terminal identifier or service identifier.

15. The method of claim 14, wherein the transmitted control information and paging information are in the same sub-frame.

16. The method of claim 13, wherein the group of cells is related to a tracking area.

17. The method of claim 13, further comprising:

receiving primary system information in a static manner, the primary system information containing the scheduling information that is used for receiving the paging information; and

receiving non-primary system information in a dynamic manner, the non-primary information containing the control information.

18. The method of claim 17, wherein the scheduling information indicates at least one of a time characteristic and a frequency characteristic of the non-primary system information.

19. The method of claim 18, wherein the time characteristic and the frequency characteristic indicate a location of the non-primary system information to be read by the particular terminal.

20. The method of claim 19, wherein the primary system information further comprises an indicator for indicating a particular terminal.

21. The method of claim 20, wherein the indicator comprises:

at least one of a terminal identifier, a service identifier, and a logical channel identifier.

22. The method of claim 18, wherein the time characteristic relates to symbols and the frequency characteristic relates to sub-carriers.

23. The method of claim 13, wherein the paging information is in the form of at least one resource block.

24. The method of claim 13, wherein the control information related to paging and notification, and other resource blocks are received via a center frequency among broadband frequencies used for a system bandwidth.

25. The method of claim 24, wherein the control information is for a mobile terminal in idle mode.

26. A method for processing system information for a mobile terminal, the method comprising:

receiving primary system information in a static manner;

receiving non-primary system information in a dynamic manner based on the primary system information, the non-primary system information comprising control information that includes separate information for idle mode and active mode; and

reading actual data by using the received control information according to whether the mobile terminal is operating in idle mode or active mode.

27. The method of claim 26, wherein the static primary system information includes scheduling information that indicates time and frequency information of the non-primary system information.

28. A method for processing system information for a network, the method comprising:

transmitting primary system information in a static manner;

transmitting non-primary system information in a dynamic manner based on the primary system information, the non-primary system information comprising control information that includes separate information for idle mode and active mode; and

transmitting actual data to be read by a mobile terminal that uses the control information according to its operation in idle mode or active mode.

29. The method of claim 28, wherein the static primary system information includes scheduling information that indicates time and frequency information of the non-primary system information.
