Abstract

A method and apparatus for reregistering a communication device in a net within a group communication network provides for receiving an indication from a controller that the communication device has been unregistered from a net. The method and apparatus allows for reregistering the communication device to become a participant in the net. In one aspect of the invention, the indication follows a lack of response from the communication device to a request from the controller inquiring whether the communication device wishes to stay a participant in the net. In another aspect, the communication device is a push-to-talk (PTT) device.

Claims

1. In a communication device, a method for reregistering in a net within a group communication network, the method comprising:

receiving an indication from a controller that the communication device has been unregistered from a net; and

reregistering the communication device to become a participant in the net.

2. The method of claim 1, wherein receiving the indication follows a lack of response from the communication device to a request from the controller inquiring whether the communication device wishes to stay a participant in the net.

3. In a communication device, a method for reregistering in a net within a group communication network, the method comprising:

receiving an indication that a user wishes to engage in a point-to-point call, the communication device being registered in a net;

un-registering the communication device from the net;

allowing the user to engage in the point-to-point call;

receiving an indication that the point-to-point call is terminated; and

reregistering the communication device to become a participant in the net;

4. In a communication device, a computer-readable medium embodying a method for reregistering in a net within a group communication network, the method comprising:

receiving an indication from a controller that the communication device has been unregistered from a net; and

reregistering the communication device to become a participant in the net.

5. In a communication device, a computer-readable medium embodying a method for reregistering in a net within a group communication network, the method comprising:

receiving an indication that a user wishes to engage in a point-to-point call, the communication device being registered in a net;

un-registering the communication device from the net;

allowing the user to engage in the point-to-point call;

receiving an indication that the point-to-point call is terminated; and

reregistering the communication device to become a participant in the net.

6. A communication device for reregistering in a net within a group communication network, comprising:

means for receiving an indication from a controller that the communication device has been unregistered from a net; and

means for reregistering the communication device to become a participant in the net.

7. A communication device for reregistering in a net within a group communication network, comprising:

means for receiving an indication that a user wishes to engage in a point-to-point call, the communication device being registered in a net;

means for un-registering the communication device from the net;

means for allowing the user to engage in the point-to-point call;

means for receiving an indication that the point-to-point call is terminated; and

means for reregistering the communication device to become a participant in the net.

8. A communication device for reregistering in a net within a group communication network, the communication device comprising:

a memory unit;

a transmitter to send a message to a controller;

a receiver to receive a response from the controller; and

a processor communicatively coupled to the receiver, the transmitter, and the memory unit, the processor being capable of;

receiving an indication from a controller that the communication device has been unregistered from a net; and

reregistering the communication device to become a participant in the net.

9. The communication device of claim 8, wherein the communication device is a push-to-talk (PTT) device.

10. A communication device for reregistering in a net within a group communication network, the communication device comprising:

a memory unit;

a transmitter to send a message to a controller;

a receiver to receive a response from the controller; and

a processor communicatively coupled to the receiver, the transmitter, and the memory unit, the processor being capable of;

receiving an indication that a user wishes to engage in a point-to-point call, the communication device being registered in a net;

un-registering the communication device from the net;

allowing the user to engage in the point-to-point call;

receiving an indication that the point-to-point call is terminated; and

reregistering the communication device to become a participant in the net.

11. The communication device of claim 10, wherein the communication device is a push-to-talk (PTT) device.
