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 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: Un metodo y un aparato para ajustar el tamano de una ventana de busqueda por una unidad remota en un sistema de comunicacion inalambrico del modo de intervalos. En un sistema de comunicacion de modos de intervalos, la unidad remota esta en un "estado activo" durante su intervalo asignado. Mientras esta en el estado activo, el controlador en una unidad remota pasa los conjuntos seleccionados de parametros de busqueda a una maquina de busqueda. La maquina de busqueda efectua busquedas sobre estaciones base utilizando los conjuntos seleccionados de parametros de busqueda. Un parametro de busqueda, el tamano de la ventana de busqueda, es ajustado en respuesta a una fuerza de senal medida de una senal de la primera estacion base. El tamano de la ventana de busqueda ajustado es utilizado por la unidad remota cuando se buscan otras estaciones base.

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 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.

Abstract: A method and apparatus for improving the performance of a convolutional encoder used in a slotted mode communication system. In a typical slotted mo de communication system a stream of continuously convolutionally encoded symbol s 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 t he stream of symbols, the state metrics of a trellis within the decoder are initialized. Initialization of the state metrics may be such that the decodi ng process will be biased towards only valid states and away from invalid state s. In addition, the initialization may be such that there is not a bias towards any particular state within the trellis.
