Patent number: 7184418Abstract: 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.Type: GrantFiled: October 20, 2000Date of Patent: February 27, 2007Assignees: Telcordia Technologies, Inc., Toshiba America Research, Inc.Inventors: Shinichi Baba, Jyh-Cheng Chen, Ashutosh Dutta, Yasuro Shobatake, Faramak Vakil

Publication number: 20060265339Abstract: A Secure Virtual Point of Service (SVPOS) that coordinates the authentication, authorization, and identity, settlement, arbitration and non-repudiation for an electronic commercial transaction. For each commercial transaction, both the buyer and merchant authenticate itself to the SVPOS and create two unique transaction encryption keys, one for the buyer and one for the merchant. The merchant uses both encryption keys to encrypt a package that include at least product identification. The merchant and buyer calculate a hash of the package and transmit the calculated hash to the SVPOS for comparison to prevent repudiation. If the calculated hash is identical the buyer receives the merchants encryption key and decrypts the package. Payment is released by the SVPOS if the buyer is satisfied with the package via a Parlay system. If the buyer is not satisfied, said SVPOS performs arbitration between the buyer and merchant to determine if the package is correct.Type: ApplicationFiled: May 16, 2006Publication date: November 23, 2006Inventors: Faramak Vakil, Vijay Varma, Raquel Morera Sempere, Giovanni Di Crescenzo

Patent number: 7072317Abstract: A Virtual Soft-Hand-off method for wireless IP-centric CDMA networks whose routers, hosts, and mobile stations have small group multicast (SGM) capability comprises setting up an explicit synchronous multicast session among a small group of participants with dynamic group membership. Packets transmitted over the multicast session are time stamped to help maintain synchronization, and the receivers recover multiple packet flows from the multiple received signals concurrently and combine them to create a single packet flow at higher layers.Type: GrantFiled: March 22, 2002Date of Patent: July 4, 2006Assignees: Telcordia Technologies, Inc., Toshiba America Research, Inc.Inventors: Faramak Vakil, David Famolari, Shinichi Baba, Tadahiko Maeda

Patent number: 6965584Abstract: A method and system for dynamic forward assignment of IP addresses in a wireless network wherein a serving base station requests IP addresses of it neighboring cells. The serving base station then provides the requested IP addresses to the mobile stations it serves based on whether the mobile station will be entering a particular neighboring cell. Immediately upon entering the neighboring cell the mobile station establishes over the air communications with the neighboring cell's base station using one of the requested addresses. In another embodiment of the present invention each mobile unit is responsible for attaining IP addresses from the base stations of neighboring cells. Accordingly, the base stations serve as relay points for the IP address requests from the mobile unit to an address server.Type: GrantFiled: February 27, 2001Date of Patent: November 15, 2005Assignees: Telcordia Technologies, Inc., Toshiba America Research, Inc.Inventors: Prathima Agrawal, Toshikazu Kodama, Faramak Vakil, Tao Zhang

Publication number: 20050060390Abstract: A system and method are provided for adding network entities and appliances to a mobile wireless Internet. A graphical user interface on a user appliance or network entity is used to start a plug and play process. In the plug and play process a temporary IP address is assigned to the entity or appliance. The temporary address is tested for uniqueness. A search mechanism identifies and contacts a plug server that uses information from the user/operator to authenticate the user and/or validate subscription information. Upon authentication or validation the plug server dispatches an inspector agent to determine the software needs of the new entity or appliance. The plug server obtains the requested software from the software inventory and the inspector agent downloads the software onto the new entity or appliance and installs it therein. The element then uses the DRCP/DHCP client to obtain a new IP address.Type: ApplicationFiled: September 15, 2003Publication date: March 17, 2005Inventors: Faramak Vakil, Byungsuk Kim, Sunil Madhani, Eric Berg, Shinichi Baba

Publication number: 20030061351Abstract: A system and method are provided by which a wireless network service provider is able to provide and maintain a high level of quality of service for terminals in the corresponding network, by overcoming problems that result in a diminished quality of service, including handoff delays as terminals move between cells in a network and the uncertainly as to which cell the individual terminals are moving to as they roam within the network. Providing and maintaining a high level of quality of service in a wireless network includes recording a history of movements of a terminal within the wireless network, analyzing the movements of the terminal within the wireless network to compute a probability distribution of the terminal's target location, and allocating network resources, including bandwidth and priority scheme, to the terminal based on the probability distribution for the terminal.Type: ApplicationFiled: September 6, 2001Publication date: March 27, 2003Inventors: Agrawal Prathima, Baba Shinichi, Faramak Vakil

Publication number: 20030045270Abstract: A system and method are provided by which a network operator is able to detect fraudulent use of a subscriber's terminal, regardless of whether or not the subscriber is aware of the fraudulent use of her terminal. Detecting unauthorized terminal use in a wireless network includes recording a history of terminal location and registration patterns, analyzing the recorded history of location and registration patterns of the terminal, monitoring current location and registration patterns of the terminal, and requesting clarification when a deviation between said statistical analysis of the location and registration patterns of said terminal and said current location and registration patterns of said terminal is detected.Type: ApplicationFiled: September 6, 2001Publication date: March 6, 2003Inventors: Prathima Agrawal, Nobuyasu Nakjima, Yoshihiro Ohba, Faramak Vakil
