Abstract

Systems and techniques for automatically terminating a call in a communications system involve a first subscriber unit originating a call to a second subscriber unit and terminating the call when the second subscriber unit rings.

Claims

1. A method of communications, comprising:

originating a call and indicating termination of the call wherein originating the call includes sending a call message, the call message including indicating termination of the call and details of a media session type, wherein a determination to automatically terminate the call is made prior to the call origination; and

terminating automatically the call responsive to the indicated termination of the call wherein terminating automatically occurs once the originating call is received.

2. The method of claim 1, further comprising receiving a response message to the call, wherein terminating automatically the call is responsive to the indicated termination of the call and the received response message.

3. The method of claim 2, wherein the received response message indicates ringing.

4. The method of claim 1, wherein the method of communications is a method of Session Initiation Protocol communications, originating a call includes sending an invite message, and terminating automatically the call responsive to the indicated termination of the call includes sending a cancel message.

5. A method of communications, comprising:

sending a call message that initiates a call and includes details of a media session type;

sending a call notification message responsive to the call message, the call notification message providing notification of the call;

sending a confirmation message responsive to the call notification message, the confirmation message confirming receipt of the call notification message;

sending automatically a termination message responsive to the confirmation message, wherein a determination to automatically send the termination message is made prior to the call initiation.

6. The method of claim 5, further comprising allocating a communication channel.

7. The method of claim 5, wherein allocating a communication channel includes sending a channel assignment message responsive to the call message, the channel assignment message assigning the communication channel.

8. The method of claim 6, further comprising deallocating the communication channel responsive to receiving the termination message.

9. The method of claim 6, further comprising deallocating the communication channel responsive to receiving the confirmation message.

10. A method of communications, comprising:

receiving a message that initiates a call with an indication to terminate the call and details of a media session type; and

terminating the call responsive to receiving the message that initiates the call with an indication to terminate the call wherein the indication to terminate the call is automatically transmitted with the message that initiates the call, and further wherein a determination to automatically terminate the call is made prior to the call initiation.

11. A method of communications, comprising:

receiving a call message that initiates a call and includes details of a media session type;

receiving an indication that the call is a ring-only call;

sending a call notification message responsive to the call message, the call notification

message providing notification of the call; and

sending automatically a termination message responsive to the indication that the call is a ring-only call, the termination message terminating the call, wherein a determination to automatically terminate the call is made prior to the call initiation.

12. A subscriber station, comprising:

a call origination unit configured to originate a call, indicate termination of the call, and include details of a media session type; and

a terminating unit configured to terminate the call automatically wherein the originated call is automatically terminated once the originated call is received and the originated call includes and indication to terminate the call, wherein a determination to automatically terminate the call is made prior to the call initiation.

14. The subscriber station of claim 12, wherein the terminating unit is configured to terminate the call automatically responsive to an indicated termination of the call.

15. The subscriber station of claim 12, wherein the terminating unit is configured to terminate the call automatically responsive to an indication of ringing.

16. The subscriber station of claim 12, further comprising a receive unit configured to receive a response message to the call.

17. The subscriber station of claim 16, wherein the subscriber station is configured to terminate the call automatically responsive to receiving a response message to the call.

13. A subscriber station, comprising:

means for originating a call;

means for indicating termination of the call and details of a media session type; and

means for terminating the call automatically once the originated call is received by a subscriber station, wherein a determination to automatically terminate the call is made prior to the call initiation.

18. A subscriber station, comprising:

a receive unit that receives a message that initiates a call with an indication to terminate the call and details of a media session type;

a terminating unit that automatically terminates the call responsive to receiving the message that initiates the call with an indication to terminate the call, wherein a determination to automatically terminate the call is made prior to the call initiation.

19. A subscriber station, comprising:

means for receiving a message that initiates a call with an indication to automatically terminate the call and details of a media session type;

means for terminating the call responsive to receiving the message that initiates the call with an indication to automatically terminate the call, wherein a determination to automatically terminate the call is made prior to the call initiation.
