Abstract: A method of adjusting a power control setpoint threshold (216) in a wireless communication system is provided. The method includes the steps of receiving at a receiver, a communication signal from a mobile communication unit to form a received communication signal, generating a first signal quality indicator (193) based on the received communication signal, generating a second signal quality indicator (194) based on the received communication signal, and generating an estimated signal-to-noise ratio (98). The method further includes setting a predetermined reference region (605) centered around a second signal quality indicator reference (206) where the second signal quality indicator reference (206) is related to the first signal quality indicator (193), and adjusting the power control setpoint threshold (216) based on a comparison between the second quality indicator (194) and the predetermined reference region (605).

Abstract: The present invention provides a method and apparatus for performing a multi-party communication in a communication system (100). The communication system (100) includes a first base unit (203) in communication with a first mobile unit (201) and a second base unit (204) in communication with a second mobile unit (202). The first base unit (203) and the second base unit (204) each include a decoder (213, 214), an encoder (223, 274) and a logic unit (233, 224). A communication is initiated between the first mobile unit (201) and the second mobile unit (202). The decoder (213) and the encoder 223 are bypassed in the first base unit (203) by the speech packets. A need is determined to include a third communication unit (239) in the communication. The third communication unit (239) is added to the communication, and the first mobile unit (201) and the second mobile unit (202) continue to transfer speech packets therebetween by bypassing the decoder (213) and the encoder (223) in the first base unit (203).

Abstract: To address the need for dispatch in a CDMA communication system, each mobile unit ( 309, 319 ) and CBSC ( 301, 311 ) involved in a call are allowed to establish an independent RLP session between them. Each session contains its own unique RLP sequence numbers that are not shared. Reverse link sequence numbers are passed from the source CBSC ( 301, 311 ) (serving the "talking" mobile) to the target CBSC(s) ( 301, 311 ) (serving the "listening" mobiles). However, instead of being directly used by the target CBSC(s) ( 301, 311 ) for its forward link RLP sequence number, the sequence numbers passed to the CBSC ( 301, 311 ) is translated to the existing target CBSCs ( 301, 311 ) current RLP sequence numbers.

Abstract: The present invention provides a method for determining a need to retransmit a message that includes a user frame from a base station (104) in a communication system (100). A signaling message is inserted into the user frame. The user frame is transmitted from the base station (104) and received at a mobile unit (102). The mobile unit (102) transmits an erasure indicator bit to indicate that the user frame was received by the mobile unit (102). The base station (104) receives the erasure indicator bit. It is then determined, based at least in part upon the erasure indicator bit, whether the signaling message was accurately transmitted by the base station (104) and received by the mobile unit (102). If the signaling message was not accurately transmitted and received, the base station (104) will retrieve the stored signaling message and retransmit the signaling message to the mobile unit (102).

Abstract: An apparatus (200) for providing a multi-party speech connection for use in a wireless communication system (10). The apparatus (200) comprises a first speech encoder (202) producing a first encoded speech signal, a second speech encoder (20) producing a second encoded speech signal, a conference circuit (22), and a speech decoder (208) responsive to the conference circuit (22). The conference circuit (22) receives the first and second speech encoded signals and produces a multiplexed encoded speech signal. The speech decoder (208) receives the multiplexed encoded speech signal and produces a decoded speech signal.

Abstract: A method and system for controlling an encoding rate in a communication system utilizes feedforward rate information (48) and/or rate desirability information (50) sent from each of a plurality of variable rate vocoders (34) to a communication link output controller (24), such as a network arbitor. The communication link output controller (24) then sends a feedback control signal (32) to a selected variable rate vocoder to change the encoding rate of the selected variable rate vocoder to facilitate re-encoding of the speech packet when a bottleneck is detected. In another embodiment, the network arbitor (134) may additionally and independently modify speech packet data when it determines that a bottleneck may occur. The network arbitor (134) also communicates a packet modification control signal (132) for the variable rate vocoder that generated the dropped packet so that the corresponding variable rate vocoder can adjust its filter states to maintain convergence.
