Abstract
A method and apparatus for indicating an expected level of quality in a private Push To Talk (PTT) network are disclosed. The method and apparatus receive at least one of an affiliation message and a talkgroup call request for a first subscriber unit of the private PTT network wherein a talkgroup is associated with at least one of the private PTT network, another PTT network, and a public network. The method and system determine an expected level of quality for the talkgroup and send the determined expected level of quality to the subscriber unit.

A method for indicating an expected level of quality in a private Push To Talk (PTT) network, the method comprising the steps of:
- at a PTT controller of the private PTT network:
- receiving an affiliation message for a first subscriber unit of the private PTT network wherein the affiliation message identifies a talkgroup for the first subscriber unit, wherein the talkgroup is associated with at least one of the private PTT network, another PTT network, and a public network;
- determining an expected level of quality for the affiliated talkgroup prior to a talkgroup call taking place for the affiliated talkgroup;
- and
- sending the determined expected level of quality to the subscriber unit.
In a private Push To Talk (PTT) network having a PTT controller and a plurality of subscriber units affiliated with a talkgroup, a method for indicating an expected level of quality, the method comprising the steps of:
- at a subscriber unit in the private PTT network:
- sending an affiliation message by the subscriber unit to the PTT controller wherein the affiliation message identifies a talkgroup for the subscriber unit, wherein the talkgroup is associated with at least one of the private PTT network, another PTT network, and a public network;
- receiving a message by the PTT controller with an expected level of quality for the affiliated talkgroup, wherein the expected level of quality is determined prior to a talkgroup call taking place for the affiliated talkgroup;
- and
- indicating the expected level of quality for the affiliated talkgroup to a user of the subscriber unit.
A system for indicating an expected level of quality for a talkgroup call in a private Push To Talk (PTT) network comprising:
- a receiver for receiving messages which communicate information about an expected level of quality for a talkgroup call in the private PTT network, wherein the expected level of quality is determined before placing the talkgroup call;
- a selector which chooses a talkgroup of the talkgroup call by locking onto a specific frequency in the private PTT network;
- a transmitter to communicate the selected talkgroup to a PTT controller of the private PTT network;
- and
- an indicator which signals the information about the expected level of quality to a user of the system,
- wherein the operation of the receiver, the selector, the transmitter, and the indicator are controlled by a processor of the processor.
