Abstract: Se divulgan un método y aparato de desintercalar bloques de datos intercalados expandidos, particularmente para usar en un sistema de telecomunicaciones inalámbrico tal como el provisto por la norma del Third Generation Partnership Project (3G). Los datos se procesan en base a un elemento secuencial, donde cada elemento tiene una cantidad predeterminada de bits M, bits que están contenidos en un bloque de palabras de datos secuenciales W'. Los elementos se extraen del bloque de palabras W' en orden secuencial, extrayéndose cada elemento de una o dos palabras secuenciales intercaladas dentro del conjunto de palabras W'. Los elementos se almacenan en un lugar selectivo dentro de un conjunto de palabras W de una memoria desintercaladora de forma que al completarse la extraccion y escritura de todos los elementos, las palabras W de la memoria de la de la desintercaladora pueden leerse secuencialmente de modo de corresponder a un bloque de bits de datos original a partir del cual se creo el bloque de elementos intercalados. El procedimiento convencional adicional da como resultado la contraccion de las palabras expandidas desintercaladas para reproducir el bloque de bits de datos en un receptor tal como originalmente disenado para transmision en un transmisor.

Abstract: A method and apparatus are disclosed for deinterleaving expanded interleaved data blocks, particularly for use in a wireless telecommunications system such as provided by the Third Generation Partnership Project (3G) standard. The data is processed on a sequential element basis where each element has a pre-determined number of bits M which bits are contained in a block of sequential data words W'. The elements are extracted from the block of words W' in sequential order, each element being extracted from either a single or two sequential interleaved words within the set of words W'. The elements are stored in selective location within a set of words W of a deinterleaver memory such that upon completion of the extraction and writing of all the elements, the words W from the deinterleaver memory can be sequentially read out to correspond to an original data block of bits from which the block of interleaved elements was created. Additional conventional processing results in the contraction of the deinterleaved expanded words to reproduce the data block of bits in a receiver as originally designated for transmission in a transmitter.

Abstract: A system and method for supporting mobile Internet communication is provided which employs a plurality of Routers and a plurality of Mobile Nodes (MNs). Each Router has a unique communication address. Each MN is associated with a home Retour. Each Router has an associated Mobile Node Location List identifying each MN for which the Router is the home Router and the communication address of a Router corresponding to a current location of eac h such MN. Each MN is movable from an old location where the MN communicates with the Internet via one Router to a current location where the MN communicates with the Internet via a different Router. Communication at the current location via the different Router is established by communicating to the MN's home Router the communication address of the different Router as th e communication address corresponding to the MN's current location. Accordingl y, a data communication from a corersponding node (CN) to a selected MN is communicated to the selected MN by accessing the Mobile Node Location List o f the selected MN's home Router to determine the communication address corresponding to the selected MN's current location and directing the data communication to that determined communication address.
