Abstract: A method and apparatus for performing an inter-system soft handoff is described. In accordance with the present invention, when a subscriber unit crosses from a first cellular system to a second cellular system, a base station controller determines if sufficient network resources are available to conduct a inter-system soft handoff. If so, the base station controller generates a set of signaling messages that cause call processing resource to be allocated and for the call to be processed at the second cellular system. The base station controller then perform data-selection and data-broadcast for the call by transmitting data to the subscriber unit by way of the second cellular system as well as via one or more base stations to which the base station controller is directly coupled. The determination as to whether sufficient network resources are available to conduct the inter-system soft handoff is based on the type of connection that exists between the first cellular system and the second cellular system, the number of inter-system calls being conducted, and the frame offset of the call currently being processed.

Abstract: A novel and improved method of acquisition in a spread spectrum communicatio n system is presented. In the present invention, a large window of PN chip offset hypotheses are searched which are generated b y a PN sequence generator (20) under the control of a se archer controller (18). The energy of the despread sequence which is despread by a despreader (6) is found that might indicate the presence of the pilot signal in a threshold comparer (16) having one of the chip offsets of the large search window, then a search of a subset o f offset hypotheses, or small window, is searched under the control of searcher contr oller (18).

Abstract: First and second data sources transmit a data signal on a data connection and a transmit clock signal on a clock connection. The data signal is clocked into a FIFO resident in the network interface equipment in response to the transmit clock signal, and out of the FIFO to the network in response to a reference clock signal. The FIFO generates a signal indicating how full it is and a local clock generator which generates the transmit clock signal in response to this status indication signal. The first and second data sources hold the data signal and transmit clock signal high for longer than a single period of the reference clock signal when switching between them. The local clock generator alters an average rate of the transmit clock signal in response to the status indication signal from the FIFO in order to keep it half-full.

Abstract: Se presenta un método novedoso y mejorado para la adquisicion en un sistema de comunicacion de espectro difundido. En la presente invencion, se busca una ventana grande de hipotesis de desplazamiento del chip de PN, las cuales se generan mediante un generador de secuencia de PN (20) bajo el control de un controlador explorador (18). Se encuentra que la energía de la secuencia recolectada que se recolecta mediante un recolector (6) podría indicar la presencia de la señal piloto en un comparador de umbral (16) que tiene uno de los desplazamientos de chip de la ventana de busqueda grande, entonces se busca una busqueda de un subconjunto de hipotesis de desplazamiento, o de ventana pequeña, bajo el control del controlador explorador (18).
