  • Publication number: 20030021248
    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.

  • Publication number: 20030004131
    Abstract: The invention provides medicaments comprising an oenothein, including topical formulations for use as free radical scavengers, or to treat irritation, or to treat inflammation. The oenothein for use in such formulations, such as oenothein-A or oenothein-B, may be purified from natural sources, such as plant material (e.g. Epilobium angustifolium).

  • Publication number: 20020186752
    Abstract: A spreader (216) comprises a code generator (301) and exclusive OR circuitry (303). In the preferred embodiment of the present invention the code generator (301) generates a code having a length and value dependent upon the current transmission rate. This code is then exclusive OR'd with the incoming data stream to produce spread data.

  • Patent number: 6249894
    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).

  • Patent number: 6169732
    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).
