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: In one disclosed embodiment, communication between a mobile unit and a base station is performed at a data transfer rate selected from, for example, a finite set of HDR data transfer rates. Meanwhile, the mobile unit continually computes a moving average of the data transfer rates. The mobile unit also ascertains a supportable data rate for receiving data. The supportable data rate can be selected from a finite set of HDR data transfer rates. In order to maintain the moving average of the data transfer rate within a specified range, the mobile unit transmits maximum data rate requests or null data requests to the base station. The maximum data rates requested by the mobile unit are equal to or lower than the supportable data rate.

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 mobile user terminal 402 accesses a packet data network 450 through one or more of several network access points 404-412. One or more control points 432-440 determines which network access point or points the user terminal is to access. Control may be retained in the current control point, or transferred to another control point, whenever it is convenient. There are preferably several routers, each having an associated home agent 418-420 which determines which foreign agents need to be accessed on behalf of each user terminal. There are several foreign agents 422-430, which forward packets received from a user terminal's home agent to the control point currently controlling communications with the user terminal.
