Abstract: A method and system for time aligning a frame (60) in a communication network (10) involves the steps of: i) determining if a frame needs to be advanced at a BTS (14), and ii) sending a shortened synchronization pattern from the BSC (12). The BTS (14) then determines if a short or long synchronization pattern has been sent by determining (256) if the received data stream matches a long synchronization pattern and setting a first flag when they do match. If the received data stream does not match the long synchronization pattern and the first flag is set (264), the data stream is compared (266) to the short synchronization pattern. When they match a second flag is set (268).

Abstract: A method and apparatus for packet alignment in a simulcast system includes a communications controller (310) having a vocoder and an input/output (I/O) processor (313) controlling the vocoder (311), the I/O processor having a timing alignment control (315) and a packet counter (314) for inserting timing alignment tags in voice/data packets and adjusting packet numbering and timing based on alignment requests from a master radio communication unit. The communications controller is coupled to radio communication units (330, 340, 350), each having a packet buffer (331) and an alignment processor (332) which includes a packet number detector (333) for detecting the transmission timing tag and sending a request for a packet numbering adjustment to the communications controller and a timing alignment detector (334) for comparing a receive time of the first information packet and a predetermined preferential receive time and for sending a timing alignment request to the communications controller.

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: 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: 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: 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: Vocoder (200) bypass is provided using in-band signaling. In preferred embodiments of the present invention, three signaling channels (see the Figure) are arranged for transmission within the compressed speech. Each of the signaling channels is communicated at a preferred rate to permit fast, reliable detection of conditions indicating vocoder bypass mode of operations, to negotiate suitable vocoder type if necessary, and to synchronize and communicate compressed speech in a vocoder bypass mode of operation.
