摘要： According to one embodiment, a communication server is provided with a communication interface unit, a storage unit, a setting unit and a roaming unit. The storage unit stores terminal list containing terminal ID and position ID (pID) of a content output terminal on a network. The setting unit transmits an instruction to set a session for outputting a content on the terminal, upon receiving from the terminal a first message containing user ID (uID), user position ID (upID) and content information associated with the session. The roaming unit selects, when a second message containing the uID and the upID is received, and it is determined that the user moved, a terminal having a pID corresponding to the upID, and transmits, to devices associated with session roaming to the selected terminal, an instruction to perform the session roaming.

摘要： A semiconductor integrated circuit for a radio communication terminal sequentially uses a plurality of frequency channels by instructions from a hopping frequency decision unit to receive packet data by a reception unit. When the integrated circuit cannot detect the head of the packet data in reception operations, the integrated circuit cannot receive packet data should be received originally then assumes that the received packet data is a packet error. And the integrated circuit calculates packet error rates for each frequency channel on the basis of the number of times of reception operations performed for each frequency channel and of the number of times of packet errors to estimate channel qualities by using the packet error rates.

摘要： An ATM cell transmission route is formed by hierarchically connecting a plurality of buses for connecting at least one first device and a plurality of second devices, and an ATM cell is to be transmitted from a first device designed to transmit/receive ATM cells and connected to one of the plurality of buses. The first device generates an ATM cell transmission message by inserting the ATM cell into a message in a format depending on the bus, and outputs an address for designating a device as the destination of the ATM cell transmission message by using a bus identifier for identifying one of the plurality of buses and a device identifier for identifying one of the plurality of devices. The ATM cell transmission message is then written in the device designated by the address. With this operation, an ATM communication system having a simple arrangement can be provided. In addition, ATM communication can be performed, with the QOS (quality of service) being guaranteed by priority control of an arbiter connected to one of the plurality of buses.

摘要： The present invention is directed to a mobility management protocol for supporting real-time and non-real-time multimedia applications on mobile stations of third generation internet protocol (3G-IP) networks. The present invention utilizes as well as extends the session initiation protocol (SIP) to provide for domain hand-off (i.e., roaming) and subnet hand-off (i.e., macro-mobility) so that users can access the network from any location using their own mobile station as they roam across different 3G-IP networks. The present invention supports mobile transmission control protocol (TCP) applications without modifying TCP. More specifically, disclosed herein is: a novel use of the SIP INVITE method for IP address binding; a novel use of the SIP INFO method to provide a means of profile verification and IP address binding; a novel use of the SIP REGISTER method to allow a SIP registrar to obtain a new IP address from a Dynamic Host Configuration Protocol (DHCP) server on behalf of the mobile; and an inventive entity called a SIP_EYE Agent that maintains a record of ongoing TCP connections and releases within the mobile.
