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 for receiving information in a mobile terminal of a mobile communication system, the method comprising:

receiving, on a first downlink channel, control information and scheduling information, the control information indicating to the mobile terminal whether paging information is to be received, wherein the scheduling information comprises time information and frequency information, the time information indicating a time for which the paging information can be received and the frequency information indicating a frequency at which the paging information can be received, and wherein the scheduling information is for receiving the paging information if the control information indicates the existence of the paging information to be received by the mobile terminal; and

receiving the paging information on a second downlink channel according to the received scheduling information, wherein the control information, the scheduling information, and the paging information are received during a same sub-frame.

2. The method of claim 1, wherein the first downlink channel is a channel on which control information for a corresponding frame is transmitted.

3. The method of claim 1, wherein the control information comprises a mobile terminal identifier or a service identifier.

4. The method of claim 1, wherein the mobile terminal receives the control information on the first downlink channel in a periodic manner.

5. A method for transmitting information from a network in a mobile communication system, the method comprising:

transmitting, on a first downlink channel, control information and scheduling information, wherein the scheduling information comprises time information and frequency information, the time information indicating a time for which the paging information can be received by a mobile terminal and the frequency information indicating a frequency at which the paging information can be received by the mobile terminal, the control information indicating whether paging information is to be received by the mobile terminal and the scheduling information is for receiving the paging information by the mobile terminal if the control information indicates the existence of the paging information to be received by the mobile terminal; and

transmitting the paging information on a second downlink channel according to the scheduling information, wherein the control information, the scheduling information, and the paging information are transmitted during a same sub-frame.

6. The method of claim 5, wherein the first control downlink channel is a channel on which control information for a corresponding frame is transmitted.

7. The method of claim 5, wherein the control information comprises a mobile terminal identifier or a service identifier.

8. The method of claim 5, wherein the control information is transmitted on the first downlink channel in a periodic manner.
