Abstract

Provided is a method for providing a service, and a method and an apparatus for allocating a resource in a wireless communication system. Services to be provided to users are divided into one of primary and secondary services based on priority in terms of frequency utilization. A service is provided using frequency channel remaining after being used in the primary service in a time zone when frequency utilization rate of the primary service is a threshold value or less. Accordingly, when service data corresponding to the secondary service are received, a user terminal stores the service data in a storage unit. Then, when the user requests provision of the corresponding service, the user terminal provides the stored service data to the user.

Claims

1. A method for a radio access apparatus to allocate a resource in a wireless communication system, comprising:

dividing services to be provided to users into one of first and second services;

searching a frequency utilization rate of a service divided as the first service; and

allocating the frequency channel remaining after being used in the first service to a service divided as the second service when the frequency utilization rate is a threshold value or less.

2. The method for allocating the resource of claim 1, wherein

the dividing includes

dividing the services to be provided to the users into one of first and second services based on service request information by the user.

3. The method for allocating the resource of claim 1, wherein

the dividing includes

dividing the services to be provided to the users into one of first and second services based on service identification information received from a corresponding contents provider through a control channel.

4. The method for allocating the resource of claim 2, wherein

the first service is a service of which service data is provided to the user in real time, and the second service is a remaining service except for the first service.

5. The method for allocating the resource of claim 4, wherein

the user terminal determines the start and end of reception of service data corresponding to the first service based on control commands from the user, and determines the start and end of reception of service data corresponding to the second service based on the start and end of transmission of service data of the radio access terminal.

6. A method for providing a service by a user terminal in a wireless communication system, comprising:

receiving resource allocation information from a radio access apparatus that allocates radio resources for each service in a manner such that frequency channel is preferentially allocated to a first service, and when frequency utilization rate of the first service is a threshold value or less, frequency channel remaining after being used in the first service is allocated to a second service;

when received service data corresponds to the second service, storing the received service data in a storage unit; and

when a user requests provision of the second service, providing the service data stored in the storage unit to the user.

7. The method for providing the service of claim 6, further comprising:

when the received service data corresponds to the first service, providing the received service data to the user.

8. The method for providing the service of claim 6, wherein

the start and end of reception of service data corresponding to the first service are determined by request of the user, and

the start and end of reception of service data corresponding to the second service are determined by resource allocation by the radio access apparatus.

9. An apparatus for allocating a resource in a wireless communication system, comprising:

a resource allocating unit that divides services to be provided to users into one of first and second services, preferentially allocates frequency channel to the service divided as the first service, and when a frequency utilization rate of the first service is a threshold value or less, allocates frequency channel remaining after being used in the first service to the service divided as the second service; and

a wireless communication module that provides service data to a user terminal based on radio resources allocated for each service in the resource allocating unit.

10. The apparatus for allocating the resource of claim 9, wherein

the first service is a service in which service data is provided to the user in real time, and the second service is a remaining service except for the first service.

11. The apparatus for allocating the resource of claim 10, wherein

the first service includes a mobile communication service and a Wibro service, and the second service includes a broadcasting and communication convergence service.
