Abstract: In a packet-based communications system where each packet includes a header and an associated data portion, message packets are communicated between entities on a radio communications network through a data gateway. The other network uses a standard internetwork protocol (IP). Predetermined fields in the standard IP header of each message packet are eliminated to obtain a modified radio network layer header before transmitting message packets over the radio network. Conversely, one or more predetermined fields are added to the modified header to convert that modified header into a corresponding standard IP header before transmission over the other network. Short and long versions of the modified radio network layer header are used with the short header version being used by radios to support network layer communications with minimal impact to the radios. Enough information is preserved in the reduced IP network header so that the standard IP header may be reassembled/reconstructed.

Abstract: A method and device are provided for encoding surperframe phase (SFP) and packer channel feedback (PCF) information into a coded superframe phase/packet channel feedback (CSFP/PCF) field. More particularly, the channel coding method is directed to distinguishing among a DCCH, a DTC and a packet data channel (PDCH). An exclusive-OR function may be performed on the logical value of the SFP before transmittal. In this way, transmitted SFP values exhibit a generally decreasing trend on a PDCH.

Abstract: A method for reassigning mobile stations a new phase within a channel is disclosed. In a communication system, a plurality of mobile stations attempt to communicate on a limited number of channels. The invention first uses a general allocation method to approximately evenly distribute the mobile stations on the available channels. After a mobile station begins active communication on the system, a second allocation method is used to change the phase of some mobile stations on a channel which has become heavily loaded. In addition, a message can also be sent to mobile stations assigned to but not yet actively communicating on the heavily loaded channel indicating that the mobile stations should change to a new channel.

Abstract: Orthogonalization techniques are disclosed which can be used, for example, to improve subtraction of CDMA signals from a composite spread spectrum signal or to improve detection of CDMA signals from the composite spread spectrum signal. According to exemplary embodiments, a Gram-Schmidt orthogonalization process is used to modify signature sequences which are each associated with a particular CDMA signal in the spread spectrum composite signal. These modified signature sequences can then be used to spread correlations of the original signature sequences in the subtraction process or in the detection process to improve performance. Pre-orthogonalization according to the present invention, eliminates or mitigates multiple access interference.

Abstract: A system and method for indicating to a user that an operable connection or non-operable connection has been made between a portable radio and a vehicle kit forming a mobile communication system. The system determines if an operable connection has been made by determining if a hands-free-request signal, an external power signal, and an external antenna signal are present. Detection of the hands-free-request signal, external power signal, and external antenna signal are indicative that the portable radio and vehicle kit are operably connected such that the mobile communication system is fully operational. An operable connection alert indicative of an operable connection between the portable radio and vehicle kit is generated by a radio display and an external speaker in response to a determination that the hands-free-signal, external power signal and external antenna signal are present. In the preferred embodiment, the external antenna signal is determined by either comparing a measured received signal strength indicating (RSSI) with a reference RSSI value or detecting an increase in RSSI after inserting the portable radio into the cradle of the vehicle kit.

Abstract: During handover of a cellular terminal (120) from a wide area cell station (102) to a base station (110), authentication messages (126a, 124a, 124b, 126b) are relayed between the wide area cell station (102) and the base station (110) via the cellular terminal (120). Communications between the cellular terminal (120) and the wire telephone network (108) via the base station (110) are prevented until after authentication takes place. Accordingly, the cellular terminal (120) relays authentication messages (126a, 124a, 124b, 126b) between the wide area cell station (102) and the base station (110). Use of the wire telephone network (108) for authentication between the cellular terminal (120) and the base station (110) is avoided. Secure handover is thereby provided without incurring excess overhead to the system and without adding unnecessary wire network charges to the cellular terminal user.

Abstract: A circuit is disclosed for switching power to a battery operated device, particularly a portable radio transceiver. The power control circuit uses an on/off switch that remains in a fixed "on" or "off" position instead of using a momentary push button switch. The circuit allows powering down the radio to prevent deep discharging of the battery even though the switch remains in the "on" position. Also, the circuit allows the radio to continue to be powered up under microprocessor control after the switch is placed in the "off" position.

Abstract: An echo canceling loudspeaker telephone includes a loudspeaker which produces a sound pressure wave in response to an input signal which is applied to an audio input thereof. This sound pressure wave includes a desired linear component which is a linear function of the input signal, and an undesired non-linear component which is a non-linear function of the input signal, and the sound pressure wave is transmitted along an acoustic path. A microphone is positioned in the acoustic path and converts the sound pressure wave into an output signal. An echo filter is responsive to the input signal and generates an estimated echo signal. This echo filter includes a loudspeaker model which generates an estimate of the sound pressure wave including an estimate of the linear component and an estimate of the non-linear component. This echo filter also includes an acoustic path model which generates an estimate of the acoustic path from the loudspeaker to the microphone. In addition, a subtractor subtracts the estimated echo signal from the output signal thereby reducing an echo portion of said sound signal.
