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). 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 Initiation Protocol) is used for call control and user authentication, allowing a unique phone numberto be assigned to the device so that it can be called by remote parties. Wired Equivalent Privacy (WEP) or one of its successor protocols can be used for encryption of all communication. For local calling, the device operates within a peer-to-peer mesh network in which co-operative packet forwarding occurs along nodes in a dynamically updated routing map based on battery and signal strength. The user initiates connections to other nodes based on an automatically populated buddy list displayed on the device, with status indicia that contains presence information. The only necessary user interface is a simple display panel and roller wheel for selection of chat partners, to reduce the device cost. No on-site server is required to administer. The device offers seamless group voice chat connections between users of wireless devices and land-based PC's, such that users on the peer-to-peer mesh network are fully integrated with those connected to an external chat server, as long as a node in the mesh network that is a party to the conversation is connected to the Internet through a WiFi hotspot. The parties on the local mesh network will be populated on the chat server, if accessible, so that external users can reach them. This is in contrast to carriers that sell expensive full-featured cell phones that tie a subscriber into a usage contract for a specific service and charge for data transfer. The device is designed for use by a community of users within a small geographic region, or where the user makes frequent use of wireless hotspots providing Internet connectivity such that no usage charges are incurred. The device is appropriate for enterprises that desire a low-cost out-of-the-box and simple-to-use solution for instant communication. Plus, the ability to place free international calls is attractive for global firms. International business units can set up wireless access points that serve all local mobile units, with the units themselves interconnected through the Internet.
