Method, system and apparatus for messaging between wireless mobile terminals and networked computers
First Claim
1. A communication system comprising:
- a first wireless mobile terminal for operating on a first wireless carrier network to communicate using a push-to-talk (PTT) mode;
a second wireless mobile terminal for operating on a second wireless carrier network different than the first wireless carrier network to communicate using the PTT mode;
a networked computer for operating on a packet network to communicate using the PTT mode; and
a message server operating on the packet network, and residing outside of the first and second wireless carrier networks, to exchange PTT messages among the first wireless mobile terminal, the second wireless mobile terminal and the networked computer;
said message server is configured tostore a user identification (ID) and user password for logging into an external instant messaging (IM) system,log into the external IM system as a proxy on behalf of a PTT message sender using the stored user ID and user password,determine whether an intended recipient of a PTT message is an IM client located within the external IM system, andforward the PTT message using the message sender'"'"'s external IM service account.

Abstract
A system is disclosed for messaging between wireless mobile terminals operating on wireless carrier networks and networked computers. The mobile terminals and computers include client applications for communicating messages to one another using push-to-talk modality. A server, located on a packet network outside the wireless carrier networks, forwards messages between the mobile terminals and the computers. The messages consist of text or streaming voice. The server can also include gateways for forwarding messages from the mobile terminals and computers to external email and instant messaging (IM) users. By placing the server outside wireless carrier networks and using conventional packet network protocols such as the Internet protocol (IP), the system provides seamless inter-carrier push-to-talk and/or instant messaging between mobile terminal, networked computers, and users of third-party email and IM services.

19. A method for communication using first and second wireless mobile terminals on respective different first and second wireless carrier networks to communicate using a push-to-talk (PTT) mode, and a networked computer for communicating using the PTT mode via a packet network, the method comprising:
-
exchanging PTT messages among the first wireless mobile terminal, the second wireless mobile terminal and the networked computer using a message server operating on the packet network and, residing outside of the first and second wireless carrier networks; and using the message server to store a user identification (ID) and user password for logging into an external instant messaging (IM) system, log into the external IM system as a proxy on behalf of a PTT message sender using the stored user ID and user password, determine whether an intended recipient of a PTT message is an IM client located within the external IM system, and forward the PTT message using the message sender'"'"'s external IM service account. - View Dependent Claims (20, 21, 22, 23, 24, 25)
