Abstract

For multi-person voice chat on wireless mobile devices, existing market solutions are primarily expensive full-featured PDA's with group voice chat implemented as an afterthought. The goal of these offerings is to increase the carrier's revenue stream versus offering the customer independence from subscription to carrier services. PDA's rely on point-to-point calls in a high-investment client-server architecture versus a low-cost peer-to-peer or hotspot environment optimized for wireless devices. The chat services offered by carriers are incompatible with each other, and require a server back-end residing on the carrier (e.g. Togabi PacketCHAT).

For multi-person voice chat on wireless mobile devices, existing market solutions are primarily expensive full-featured PDA's with group voice chat implemented as an afterthought. The goal of these offerings is to increase the carrier's revenue stream versus offering the customer independence from subscription to carrier services. PDA's rely on point-to-point calls in a high-investment client-server architecture versus a low-cost peer-to-peer or hotspot environment optimized for wireless devices. The chat services offered by carriers are incompatible with each other, and require a server back-end residing on the carrier (e.g. Togabi PacketCHAT).

The invention is for the provision of dedicated multi-person voice chat capabilities over a local digital wireless network through an instant messaging interface on a dedicated mobile device. It is a low-cost solution specifically designed for convenient multi-person voice communication, with no additional features. It operates on a WiFi wireless network, and is completely independent of carrier service fees. The device permits the user to communicate with another user that has the same device, or is connected to a popular Internet-based chat service.

For long-distance calling, the user can communicate with any user subscribed to a popular instant-messaging chat service with voice capabilities, through an open architecture that integrates with third party services. The user's conversation is carrier as VoIP (voice over IP on a digital packet network). The conversation is encrypted to ensure privacy. The user can engage in a conversation with several parties simultaneously, in half-duplex mode (only one speaker at a time), to reduce bandwidth. The user of the mobile device connects through a hotspot, and can store a user name and password to authenticate with the router. An open-architecture chat platform is utilitized for interoporability with major instant messaging networks, and resides on a central server. The SIP (Session Initi...
