Abstract: An inband signaling modem communicates digital data over a voice channel of a wireless telecommunications network. An input receives digital data. An encoder converts the digital data into audio tones that synthesize frequency characteristics of human speech. The digital data is also encoded to prevent voice encoding circuitry in the telecommunications network from corrupting the synthesized audio tones representing the digital data. An output then outputs the synthesized audio tones to a voice channel of a digital wireless telecommunications network.

Abstract: Systems and methods are disclosed for layered, secure data communications with a mobile unit over a variety of different communication links, such as in-band signalling, SMS, CDPD etc. A privilege control table determines permitted classes of messages. Content labeling is used to further manage communications without reading the payload of the message. The invention adds additional layers of security by varying content labels based on secure session key exchange seeded algorithms. The system also includes isolating the application program by providing a protocol manager for exclusive receipt of a communication service request from the application program; the protocol manager implementing a plurality of different message protocols. Another aspect of the invention includes link choose logic for effecting loosely-coupled, network loop communications to enable broadband delivery to a mobile unit, and can include parallel transmission of segmented messages over plural communication links.

Abstract: The invention provides for conversion of latitude and longitude to an addressing scheme that supports current TCP/IP (v4) and future addressing (v6/ng) requirements. More specifically, it allows a decentralization of the unicast point to device on the hosted network. Geographical Internet Protocol (GeoIP) addressing will facilitate anycast routing schemes where the nearest node has a statically assigned GeoIP. Geo routing, and network management become a function of the GeoIP address.

Abstract: In the case of a conventional radio telecommunication system for transmitting information between stationary transmitting/receiving units and mobile transmitting/receiving units it is proposed that the mobile units be additionally provided with a satellite navigation receiver for independently determining a position rough value. The stationary units are likewise provided with a satellite navigation receiver for independently determining a reference position rough value of a reference location of known exact geographical position as the reference position normal value, and with an error detection unit for detecting position determination errors by comparing the instantaneously determined reference position rough value with the reference position normal value.
