Abstract: A portable communication device, method, and system enable temporary access to private user information by a venue communication system. The temporary access to the private information is based on a registration that includes user selectable privacy thresholds and predetermined venue conditions. The temporary access by the venue communication system can be adjusted and limited by the portable communication device. The usage of the private data by the venue communication system may be limited to anonymous analytics and/or extended to non-anonymous analytics and notifications based on user input to the communication device.

Abstract: The invention provides a method of retransmitting a speech packet. In one embodiment, the method includes receiving (S702) at a transmitting device (140) a first negative acknowledgement (NACK) from a receiving device (120). The NAK indicates a corrupted first speech packet transmission. The transmitting device then retrieves (S706) a first speech packet associated with the first NACK and compresses (S714-S720) the speech packet to form a replacement speech packet. Next, a current segment of speech is encoded (S808) to form a current speech packet and current speech packet is combined with the replacements speech packet. The combined speech packet is then transmitted (S814) to the receiving device.

Abstract: A method, apparatus and system for accurately identifying discontinuous transmissions (DTX) and enabling the utilization of a dedicated control channel (DCCH) by determining if the frame satisfies a quality check, analyzing at least a portion of bits within the frame if the frame does not satisfy the quality check, determining if the bits analyzed exceed a threshold and identifying the frame as a DTX if the bits fail to exceed the threshold. Some embodiments further count a number of zero bits in a tail end of the frame, determine if the number of zero values exceed the threshold, determine if the frame includes an expected sequence of bits if the number of the zero bits does not exceed the threshold, and identify the frame as the DTX if the frame does not include the expected sequence.

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: In a data transmitter having a data encoder, an encoder mode is detected. Thereafter, an excluded codeword output by the encoder operating in the encoder mode is identified. Next, a selected bit in the excluded codeword caused to have a predetermined value to produce a non-excluded codeword. Finally, the excluded codeword is substituted with the non-excluded codeword, wherein the non-excluded codeword is selected to mitigate effects of a decoding error in a receiver associated with the excluded codeword.

Abstract: A remote unit's (113) volume level is controlled locally through a user interface (105). The user interface (105) converts volume-up and volume-down instructions to an appropriate volume-up or volume-down command signal which is passed through a controller (107) to a local amplifier (111). When the local amplifier (111) is operating at a maximum gain level, and a user still perceives the audio output as being inadequate, an increase in volume results in the controller (107) sending a volume-up message via transmit circuitry (103) to infrastructure equipment (115). Upon receiving the volume-up message an amplifier (125) existing within the infrastructure equipment (115) increases its gain.

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 and apparatus for determining the transmission time of packets of information in a communication system includes a temporal offset processor (330) which receives transmission delay information from a delay analyzer (315) and soft handoff state information from a control processor (320). This information is used to determine a temporal offset for packets of information. The temporal offset is used by a network arbiter (350) to determine when the associated packet should be transferred in time.

Abstract: A method and apparatus in a communication system includes establishing a communication link between a first and second mobile communication resources (111, 114) via a series of land-based communication resources (121, 131, 132, 124) which have a first and last ((121,131), (132, 125)) land-based communication resources. The first and second mobiles (111, 114) have a first and last wireless connection (161, 164) respectively. The first mobile (111) transmits in sequence sequentially numbered packets of data via the first wireless connection (161) to the first land-based communication resource (121, 131). A detecting communication resource, including one of the land-based communication resources (121, 131, 132, 124), detects reception of out of sequence packets of data, and transmits out of sequence the sequentially numbered packets of data to communication resources subsequent in series to the detecting communication resource including the second mobile (114) via the last wireless connection (164).

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 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 determining the order of transmission of packets of information in a communication system includes a priority assignment processor (330) which receives transmission delay information from a delay analyzer (315) and soft handoff state information from a control processor (320). This information is used to determine a priority level for packets of information. The priority level is used by a network arbiter (350) to determine when the associated packet should be transferred relative to other packets of information.

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).
