Abstract: A method and circuit for adaptively determining a pilot signal reacquisition time. A searcher subsystem (55) measures a phase of the pilot signal. A control processor (62) measures a magnitude of a shift in the pilot signal phase, compares the measured magnitude to a shift threshold, and decreases the reacquisition time if the measured magnitude is not greater than the shift threshold. The control processor (62) also may compare the reacquisition time to a minimum reacquisition time, and decrease the reacquisition time only if the reacquisition time is greater than the minimum reacquisition time. Additionally, the control processor (62) may increase the reacquisition time to a maximum reacquisition time if the measured magnitude is greater than said shift threshold.

Abstract: 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 enters 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 order that the searches are performed is based on the measured signal strength and the age of the measurement. The search engine performs searches using the selected sets of search parameters. Searching continues as long as the remote unit is in the active state. When the remote unit enters the inactive state, searching ceases. While in the inactive state, the controller evaluates the results of the searches performed during the previous active state. During the next active state, the next sequence of searching is performed based on measured signal strength and the measurement age corresponding to the measurements made during the previous active state.

Abstract: The invention provides a system and method for testing signal transmission quality within a digital communication system and may be incorporated within a digital cellular communication system in which information is exchanged over spread spectrum communication channels. A test sequence of digital data transmitted over the communication channel is received at a receiving station, within which is also generated a replica of the test sequence of digital data. The accuracy of transmission over the communication channel is then determined by comparing the replica of the test sequence of digital data to the test sequence of data received over the communication channel. The invention allows the test sequence of digital data to be transmitted at one of a set of known data rates, with the received station being disposed to identify the data rate associated with each test sequence of digital data. In order to simulate the transmission of, for example, voice data, the system may be configured such that each test sequence of digital data is generated in accordance with a pseudorandom process.

Abstract: 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.

Abstract: 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.

Abstract: The virtual device architecture provides physical and logical device drivers for interfacing software programs executing on a microprocessor of the mobile telephone of a wireless communication system with any of a wide variety of hardware devices connectable within the mobile telephone. The logical device drivers convert commands received from the software applications to commands appropriate for use by selected hardware devices. The physical device drivers receive the converted commands from the logical device drivers and in response to the received commands directly control the selected hardware devices. In one example described herein, the logical device drivers provide translation of core commands necessary to control the selected hardware devices and extended commands for enhanced control of the hardware devices. The logical device drivers operate to convert the extended commands into core commands prior to forwarding the commands to the physical device drivers. By providing logical and physical drivers for use with peripheral devices, the need to provide different versions of software executing on the microprocessor to accommodate different types of peripheral devices is substantially eliminated resulting in a considerable reduction in time and cost associated with developing, maintaining and upgrading software. By providing logical device drivers capable of accommodating both core commands and extended commands, a rich set of peripheral commands can be accommodated thereby further reducing or eliminating the need to provide different versions of software executing on the processor, while nevertheless exploiting the full capabilities of a wide variety of peripheral devices, including state of the art hardware devices such as bit-mapped displays, pointer devices and the like. Method and apparatus embodiments are described.

Abstract: 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.

Abstract: 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.
