Method and apparatus for managing radio resources in mobile communication system

1. An apparatus for managing radio resources at a mobile terminal, comprising:

a communication module for receiving a radio resource availability level from a base station;

a controller for comparing the received radio resource availability level with an actual level of the mobile terminal to determine whether the radio resources are available to the mobile terminal; and

a display unit for displaying a possibility of a mobile origination call and a packet switching service depending on the determination results,

wherein the actual level of the mobile terminal is classified depending on types of service subscriptions, and

wherein the mobile terminal performs cell reselection when the availability level indicating an unavailability of radio resources is received continuously over a time specified by a network operator.

2. The apparatus of claim 1 , further comprising a voice processor for outputting a voice message informing the possibility of the mobile origination call and the packet switching service depending on the determination results.

3. The apparatus of claim 1 , wherein the radio resource availability level is included in a periodically-broadcasted system information message.

4. A mobile terminal for managing radio resources, comprising:

a communication module for receiving a radio resource availability level from a base station; and

a controller for comparing the received radio resource availability level with an actual level of the mobile terminal to determine whether the radio resources are available to the mobile terminal,

wherein the actual level of the mobile terminal is classified depending on types of service subscriptions, and

wherein the mobile terminal performs cell reselection when the availability level indicating an unavailability of radio resources is received continuously over a time specified by a network operator.

5. A non-transitory computer-readable recording medium having recorded thereon a program for executing a method for managing radio resources in a mobile terminal, the method comprising:

receiving, by a first code segment, a radio resource availability level from a base station; and

comparing, by a second code segment, the received radio resource availability level with an actual level of the mobile terminal to determine whether the radio resources are available to the mobile terminal,

wherein the actual level of the mobile terminal is classified depending on types of service subscriptions, and

wherein the mobile terminal performs cell reselection when the availability level indicating an unavailability of radio resources is received continuously over a time specified by a network operator.

6. A method for managing radio resources at a mobile terminal, comprising the steps of:

receiving a radio resource availability level from a base station;

comparing the radio resource availability level with an actual level of the mobile terminal to

determine whether the radio resources are available to the mobile terminal; and

informing a user of a possibility of a mobile origination call and a packet switching service depending on the availability of the radio resources,

wherein the actual level of the mobile terminal is classified depending on types of service subscriptions, and

wherein the mobile terminal performs cell reselection when the availability level indicating an unavailability of radio resources is received continuously over a time specified by a network operator.

7. The method of claim 6 , further comprising receiving an available radio resource amount from the base station, when the radio resource availability level received.

8. The method of claim 7 , wherein determining whether the radio resources are available to the mobile terminal further comprises:

detecting a pre-stored radio resource availability level of the mobile terminal based on the available radio resource amount; and

comparing the detected radio resource availability level with the actual level of the mobile terminal to determine whether the radio resources are available to the mobile terminal.

9. The method of claim 5 , wherein informing the user of the possibility of the mobile origination call and the packet switching service further comprises informing the user of the possibility of the mobile origination call and the packet switching service, when the radio resources are available to the mobile terminal.

10. The method of claim 9 , further comprising informing the user of a temporary impossibility of the mobile origination call and the packet switching service, when the radio resources are unavailable to the mobile terminal.

11. The method of claim 5 , wherein the radio resource availability level is included in a periodically-broadcasted system information message.
