    摘要: A method of and an apparatus for reducing the average power consumption in a remote unit in a wireless communication system. When a remote unit in a slotted mode communication system receives a general paging massage, it deinterleaves and decodes the raw data samples. Prior to parsing, it compares the decoded data samples with samples stored in a memory. Based on this comparison, the remote unit determines whether or not the message is empty. If the message is empty, the remote unit transitions to an inactive state. By comparing before parsing, the remote unit is able to conserve power by entering the inactive state sooner. If no samples are stored in the memory, instead of comparing, the remote unit parses the message and executes any instructions. If, upon parsing, the remote unit determines the message to be empty, at least a portion of the message is stored in the memory.

    摘要: A method of and an apparatus for reducing the average power consumption in a remote unit in a wireless communication system. When a remote unit in a slotted mode communication system enters an active state, it receives a sequence of messages. One element of this sequence is a general paging message that command the remote unit to return to the inactive state immediately, thus conserving battery power. The general paging message is followed by several additional elements in the sequence. When the remote unit operates in a poor signal-to-noise ratio environment, for example, it may not receive the general paging message and may, thus, unnecessarily remain in the active state until the end of its assigned slot, wasting battery power. The invention determines whether the element received by the remote unit is a general paging message. If so, the remote unit enters the inactive mode. If not, the invention determines whether the element occurs after a general paging message in the sequence of messages. If so, the remote unit enters the inactive mode without waiting for the end of the assigned slot.

    摘要: A novel and improved method and apparatus for signal acquisition in a wireless telecommunication system having large transmission delay uncertainty is described. A terminal first acquires the forward link signal from a hub and extracts timing information from that forward link signal. Using the timing information the terminal estimates the time at which a next search window takes place during an access slot, and the time and pseudorandom code state necessary to transmit an access probe so as to arrive at during the search window assuming the terminal is located a maximum distance from the hub. The terminal proceeds to transmit additional access probes at times occurring one access slot period plus a delta time interval after the previous transmission. The delta time interval has a duration less than that of a search window associated with each access slot. Each access probe is processed with various transmission codes the states of which are incremented by an access slot period for each access probe transmitted.

    摘要: A method and apparatus of adjusting a search window size by a remote unit in a slotted mode wireless communication system. In a slotted mode communication system, the remote unit is in an “active state” during its assigned slot. While in the active state the controller in a remote unit passes selected sets of search parameters to a search engine. The search engine performs searches on base stations using the selected sets of search parameters. One search parameter, the search window size, is adjusted in response to a measured signal strength of a first base station signal. The adjusted search window size is used by the remote unit when searching other base stations.

    摘要: A method and apparatus for improving the performance of a convolutional encoder used in a slotted mode communication system. In a typical slotted mode communication system a stream of continuously convolutionally encoded symbols is transmitted by a base station. A remote unit, comprising a convolutional decoder to decode the stream of symbols periodically transits between active and inactive states. While in the inactive state the remote unit misses a portion of the continuous stream of symbols. Following the interruption of the stream of symbols, the state metrics of a trellis within the decoder are initialized. Initialization of the state metrics may be such that the decoding process will be biased towards only valid states and away from invalid states. In addition, the initialization may be such that there is not a bias towards any particular state within the trellis.

    摘要: A method and apparatus for improving searching in a remote unit of a slotted mode, wireless, communication system. In a slotted mode communication system, the remote unit is in an “active state” during its assigned slot. While in the active state, a controller in the remote unit passes selected sets of search parameters to a search engine. The integration interval of the searches performed is based on the measured signal strength of another base station. The search engine performs searches using the integration interval. Searching continues as long as the remote unit is in the active state. When the remote unit enters the inactive state, searching ceases.

    摘要: 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.
