Abstract

A method and apparatus for a communication system provide for fast link setup for a mobile station by transmitting a request message, transmitting an assignment message from the base station to the mobile station, and transmitting a notification message from the base station to a base station controller. The mobile station transmits an indication message to the base station controller indicating a successful completion of acquiring the data packet channel. The base station controller processes the indication message for message integrity and security feature. A portion of the available communication resources at the base station is allocated for an immediate response to the request message for acquiring a data packet channel.

Claims

1. A method for a communication system comprising:

receiving a notification message from a base station, the notification message informing a base station controller of a mobile station in process of establishing a radio link with the base station;

starting a timer at the base station controller for measuring elapsed time after receiving the notification message indicating that the mobile station is in process of establishing a radio link; and

transmitting a radio link release message from the base station controller to the base station in response to detecting expiration of the timer with respect to a timer threshold, the timer expiration indicating failure of the mobile station to acquire a channel from the base station within the timer threshold.

2. The method as recited in claim 1 further comprising:

receiving an indication message from the mobile station at the base station controller indicating successful acquisition of a data packet channel by the mobile station.

3. The method as recited in claim 2 further comprising:

processing the indication message for message integrity at the base station controller.

4. The method as recited in claim 3 further comprising:

transmitting a radio link release message from the base station controller to the base station in response to detecting a failure of the mobile station in passing the processing for message integrity.

5. The method as recited in claim 2 further comprising:

processing the indication message for security feature at the base station controller.

6. The method as recited in claim 5 further comprising:

transmitting a radio link release message from the base station controller to the base station in response to detecting a failure of the mobile station in passing the processing for security feature.

7. An apparatus for a communication system comprising:

means for receiving a notification message from a base station, the notification message informing a base station controller of a mobile station in process of establishing a radio link with the base station;

means for starting a timer at the base station controller for measuring elapsed time after receiving the notification message indicating that the mobile station is in process of establishing a radio link; and

means for transmitting a radio link release message from the base station controller to the base station in response to detecting expiration of the timer with respect to a timer threshold, the timer expiration indicating failure of the mobile station to acquire a channel from the base station within the timer threshold.

8. The apparatus as recited in claim 7, further comprising:

means for receiving an indication message from the mobile station at the base station controller indicating successful acquisition of a data packet channel.

9. The apparatus as recited in claim 8 further comprising:

means for processing the indication message for message integrity at the base station controller.

10. The apparatus as recited in claim 9 further comprising:

means for transmitting a radio link release message from the base station controller to the base station in response to detecting a failure of the mobile station in passing the processing for message integrity.

11. The apparatus as recited in claim 8 further comprising:

means for processing the indication message for security feature at the base station controller; and

means for transmitting a radio link release message from the base station controller to the base station in response to detecting a failure of the mobile station in passing the processing for security feature.

12. An apparatus for a communication system, comprising:

at least one processor operative to receive a notification message from a base station, the notification message informing a base station controller of a mobile station in process of establishing a radio link with the base station, to start a tinier at the base station controller for measuring elapsed time after receiving the notification message indicating that the mobile station is in process of establishing a radio link, and to send a radio link release message from the base station controller to the base station in response to detecting expiration of the timer with respect to a timer threshold, the timer expiration indicating failure of the mobile station to acquire a channel from the base station within the timer threshold.

13. The apparatus as recited in claim 12, wherein the at least one processor is operative to receive an indication message from the mobile station at the base station controller indicating successful acquisition of a data packet channel.

14. The apparatus as recited in claim 13, wherein the at least one processor is operative to process the indication message for message integrity at the base station controller.

15. The apparatus as recited in claim 14, wherein the at least one processor is operative to send a radio link release message from the base station controller to the base station in response to detecting a failure of the mobile station in passing the processing for message integrity.

16. The apparatus as recited in claim 13, wherein the at least one processor is operative to process the indication message for security feature at the base station controller, and to send a radio link release message from the base station controller to the base station in response to detecting a failure of the mobile station in passing the processing for security feature.

17. The apparatus as recited in claim 12, further comprising:

a communication unit coupled to the at least one processor and operative to receive the notification message from the base station and to send the radio link release message to the base station.

18. A computer-readable medium encoded with a computer program for a communication system, comprising instructions for

receiving a notification message from a base station, the notification message informing a base station controller of a mobile station in process of establishing a radio link with the base station;

starting a timer at the base station controller for measuring elapsed time after receiving the notification message indicating that the mobile Station is in process of establishing a radio link; and

sending a radio link release message from the base station controller to the base station in response to detecting expiration of the timer with respect to a timer threshold, the timer expiration indicating failure of the mobile station to acquire a channel from the base station within the timer threshold.
