Method to identify voice over packet device capability and use it to make appropriate calls with other client devices
First Claim
1. A call processing method, for set-up of a voice over packet communication via a radio access network between a mobile station and one of a plurality of client devices, at least some of the client devices having a plurality of different communication capabilities, the method comprising steps of:
- receiving registration information from the one client device;
receiving and forwarding encoded voice packet information between the mobile station and the one client device, which has been communicated through the radio access network in a manner that is compatible with a default communication capability;
in response to the received registration information, identifying a communication capability of the one client device from among the different communication capabilities;
communicating information as to the identified communication capability of the one client device, to the mobile station, through the radio access network, wherein the communication of the information as to the communication capability of the one client device to the mobile station follows completion of the receiving and forwarding of voice packet information communicated in the manner compatible with the default communication capability;
receiving encoded voice packet information from the mobile station, wherein the voice packet information has been communicated through the radio access network in one manner that is compatible with the communication capability of the client device selected from among a plurality of manners compatible with the plurality of different communication capabilities of the client devices;
forwarding the encoded voice packet information to the one client device; and
wherein the receiving and forwarding of the encoded voice packet information supports a push-to-talk service offered through the radio access network to the mobile station and the one client device.

Abstract
A system provides push-to-talk (PTT) or similar communication service via a radio access network providing wireless mobile packet data communications for mobile stations. A server distributes packets of digitized audio received from a broadcasting mobile station to one or more client devices of other parties. The called client device(s), however, may not all have the same communications capabilities as the broadcasting mobile station. Signaling procedures are adapted to inform the broadcasting station of the capabilities of the other client device(s). This enables the broadcasting mobile station to configure its transmissions of digitized audio through the network for compatibility with the capabilities of the other client device(s). Proper configuration avoids loss of data at the destination, particularly at the start of a PTT transmission, due to transmission in a form or configuration that may be incompatible with one or more of the receiving stations.
