    Abstract: A communication system that allows a soft handoff to be completed, even when the communications link between the active base station and the mobile station deteriorates before the mobile station (101) has received the handoff direction message. The mobile station maintains a list of base stations that the mobile station (101) is in communication with, referred to as an "Active Set". In addition, the mobile station (101) maintains another list of base stations (300) that are proximate to the base stations (300) in the active set. This list is referred to as the "Neighbor Set". A memory within the mobile station (101) includes information that would allow the mobile station (101) to demodulate information transmitted from those base stations (300) on the neighbor set. In accordance with the disclosed method and apparatus, the mobile station (101) places a base station (300) in the active set upon including the base station (300) in a pilot strength measurement message (PSMM).

    Abstract: A system provides wireless data service. The system includes a wireless modem configured to be coupled to a terminal equipment unit over a wireline broadcast medium. A network unit is coupled to the wireless modem over a wireless link connection. A network remote server is coupled to the network unit. The network remote server provides IP address information in response to terminal equipment unit address request messages for terminal equipment units coupled to the network unit. In addition, a local server is coupled to the wireless modem. The local server provides IP address information in response to terminal equipment unit address request messages from terminal equipment units coupled to the wireline broadcast medium.

    Abstract: A conference calling system for a wireless communications channel. The system is adapted for use with a channel having first, second and third participants communicating via first, second and third transmitters and receivers respectively. The system includes a circuit for receiving an encoded signal from at least one of the transmitters. A second circuit determines which of the participants is speaking from the received encoded signal. A third circuit is provided for re-transmitting an encoded signal received from the speaking participant to the other participants. In the illustrative implementation, the encoded signals are variable rate speech vocoded signals in which speech is vocoded at full rate, silence is vocoded at +E,fra 1/8+EE th rate and the +E,fra 1/2 +EE and +E,fra 1/4+EE rates are used as transitional rates. In the illustrative implementation, the speaker's signal is identified by examining the rate of the received vocoded signals. When the speaker's vocoded signal is identified, it is re-transmitted without de-vocoding to the non-speaking participants in the conference call. By re-transmitting the speaker's signal without de-vocoding, the quality of the received signal is preserved.

    Abstract: A method of invoking and canceling voice and data service between a mobile unit and a base station. Using a standard telephone system, the connection for a voice service and a data service is the same. With the introduction of the digital wireless link, the voice connection and the data connection are different. Therefore new dialing commands which indicate the intent of the connection are created. These commands can also be used to designate the intent of the call from a mobile unit capable of data and voice service but not capable of simultaneous voice and data service. They can also be used to invoke simultaneous voice and data services.

    Abstract: A conference calling system for a wireless communications channel. The system is adapted for use with a channel having first, second and third participants communicating via first (34), second (20) and third (20) transmitters and receivers respectively. The system includes a circuit for receiving an encoded signal (144) from at least one of the transmitters. A second circuit determines (62) which of the participants is speaking from the received encoded signal. A third circuit is provided for re-transmitting (66) an encoded signal received from the speaking participant to the other participants. In the illustrated implementation, the encoded signals are variable rate speech vocoded signals in which speech is vocoded at full rate, silence is vocoded at 1/8th rate and the 1/2 and 1/4 rates are used as transitional rates. In the illustrative implementation, the speaker's signal is identified by examining the rate of the receiving vocoded signals. When the speaker's vocoded signal is identified, it is re-transmitted without devocoding to the non-speaking participants in the conference call. By retransmitting the speaker's signal without de-vocoding, the quality of the received signal is preserved.
