Abstract: The present invention provides a communication terminal configured as a Mobile Node, MN, for use in network system that supports mobile Internet communication and has a plurality of Routers each having a unique communication address via which MNs communicate with the Internet via different Routers at different locations where 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 each such MN, the communication terminal characterized by: means for storing a unique host name and a home network identifier, HNI, that reflects an association with a home Router; and means for communicating to the terminal's home Router, when said terminal is moved from an old location where the terminal communicates with the Internet via one Router to a current location where the terminal communicates with the Internet via a different Router, the communication address of the different Router as the communication address corresponding to the terminal's current location whereby a data communication from a corresponding node, CN, to the terminal is communicated to the terminal using the terminal's HNI and unique host name by accessing the Mobile Node Location List of the terminal's home Router to determine the communication address corresponding to the terminal's current location and directing the data communication to that determined communication address.

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: The invention relates to establishing a wireless packet session between at least two users. At least one of the users is a wireless user. A first of the at least two users sends a reservation setup protocol (RSVP) PATH messag e to a second user of the two users. The RSVP PATH message includes informatio n for reserving resources for transmissions from only the first user to the second user; or from the first user to the second user and the second user to the first user, or only for transmissions from the second user to the first user. In response to receiving the RSVP PATH message, the second user transmits a RSVP reservation (RESV) message to the first user. Transmissions occur using the reserved resources.

Abstract: The invention relates to establishing a wireless packet session between at least two users ( USER A and USER B ). At least one ( USER A or USER B ) of the users is a wireless user. A first of the at least two users send a reservation setup protocol (RSVP)PATH message (30) to a second user of the t wo users. The RSVP PATH message (30) includes information for reserving resourc es for transmissions from only the first user to the second user; or from the first user to the second user and the second user to the first user, or only for transmissions from the second user to the first user. In response to receiving the RSVP PATH message (30), the second user transmits a RSVP reservation (RESV) message (32) to the first user. Transmissions occur using the reserved resources.

Abstract: A SYSTEM (10,12,20,40,42,50) AND METHOD FOR SUPPORTING MOBILE INTERNET COMMUNICATION IS PROVIDED WHICH EMPLOYS A PLURALITY OF REUTERS AND A PLURALITY OF MOBILE NODES (MNS) (30). 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 EACH 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 THE COMMUNICATION ADDRESS OF THE DIFFERENT AS THE COMMUNICATION ADDRESS CORRESPONDING TO THE MN’S CURRENT LOCATION. ACCORDINGLY, A DATA COMMUNICATION FROM A CORRESPONDING NODE (CN) TO A SELECTED MN IS COMMUNICATED TO THE SELECTED MN BY ACCESSING THE MOBILE NODE LOCATION LIST OF 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.

Abstract: An apparatus and method for DFT processing using prime factor algorithm (PFA) on a selected number P of midamble chip values received by a CDMA receiver, where P has a plurality M of relatively prime factors F, and the DFT process is divided into M successive F-point DFT processes. The P data values are retrieved from a single input port memory and selectively permuted by a controller into parallel caches to optimize factoring with associated twiddle factors stored in parallel registers. The permuted inputs are factored in two or more parallel PFA circuits that comprise adders and multipliers arranged to accommodate any size F-point DFT. The outputs of the PFA circuits are processed by consolidation circuitry in preparation for output permutation of the values which are sent to memory for subsequent DFT cycles.
