Abstract

A user who desires to establish a temporary talk group first requests a temporary group identifier, then the user specifies the talk group membership and a validity period. The temporary talk group can be set up using a mobile communication device, or by use of a computer which connects with a service provider'"'"'s server over the Internet.

Claims

1. A method for establishing a temporary simplex talk group in a wireless communication system, comprising:

initiating a talk group call set-up mode at a mobile station;

requesting a temporary group identifier from a wireless communication infrastructure;

receiving the temporary group identifier at the mobile station;

creating a temporary group list comprised of a plurality of identifiers, each of the plurality of identifiers corresponding to a subscriber to be included in the temporary simplex call group;

affiliating the temporary group list with the temporary group identifier;

selecting a validity period for the temporary simplex call group; and

transmitting the validity period and the temporary group list to the wireless communication infrastructure;

wherein the wireless communication infrastructure maintains the temporary simplex call group for a period of time equal to the validity period.

2. A method for establishing a temporary conference call group as defined in claim 1, further comprising initiating a temporary simplex call using the temporary group identifier.

3. A method for establishing a temporary conference call group as defined in claim 1, further comprising transmitting the temporary talk group identifier to other mobile stations corresponding to the plurality of identifiers.

4. A method for establishing a temporary simplex talk group in a wireless communication system, comprising:

invoking a microbrowser on a mobile station;

establishing a client-server communication session with an account server using the microbrowser;

requesting a temporary talk group identifier from the account server with the micro browser;

receiving the temporary group identifier at the mobile station;

creating a temporary group list comprised of a plurality of identifiers, each of the plurality of identifiers corresponding to a subscriber to be included in the temporary simplex call group;

affiliating the temporary group list with the temporary group identifier;

selecting a validity period for the temporary simplex call group; and

transmitting the validity period and the temporary group list to the account server;

transmitting the validity period and the temporary group list to a wireless communication infrastructure;

wherein the wireless communication infrastructure maintains the temporary simplex call group for a period of time equal to the validity period.

5. A method for establishing a temporary conference call group as defined in claim 4, further comprising initiating a temporary simplex call using the temporary group identifier.

6. A method for establishing a temporary conference call group as defined in claim 4, further comprising transmitting the temporary talk group identifier to other mobile stations corresponding to the plurality of identifiers.
