Publication number: 20100074105Abstract: Some embodiments of the invention provide an implementation for a multi-hop wireless backhaul network. These embodiments can advantageously be deployed in dense urban areas and/or co-located with wireless access nodes, such as base-stations of a cellular wireless communication system. Preferably wireless links between constituent network nodes are set-up hierarchically. A basic result of this is that peer-to-peer (child-to-child) communication is generally prohibited and circuits are forced to conform to a topology. The multi-hop wireless backhaul network may be used to carry delay sensitive, high-density last mile circuit traffic over Non-Line-Of-Sight (NLOS) broadband radio links. Moreover, some embodiments of the invention provide a method of path-healing for re-routing of circuit traffic from circuits that have experienced catastrophic failures.Type: ApplicationFiled: November 24, 2009Publication date: March 25, 2010Inventors: Shalini Periyalwar, Hang Zhang, Glenn Algie, Peiying Zhu, Robert Matyas, Claude Royer, Bill Gage, James Mark Naden, Alauddin Javed

Patent number: 7583632Abstract: The present invention facilitates a handoff between cellular and wireless local area networks (WLANs). To facilitate a WLAN interface with the cellular network, a proxy packet control function (P-PCF) establishes a data tunnel to a packet data serving node (PDSN), as well as a WLAN association with a mobile terminal. The WLAN association is a tunnel, and is preferably implemented via an Access Router acting as a liaison between the proxy PCF and an Access Point. The Access Router and the proxy PCF establish an IP tunnel, which carries the WLAN user's PPP traffic. Handoffs between the cellular and WLAN networks are facilitated by effecting a same-PDSN, inter-PCF handoff wherein the communication session with the mobile terminal is effectively changed from between the PDSN and the proxy PCF to between the PDSN and a PCF associated with a base station controller facilitating the cellular access, and vice versa.Type: GrantFiled: December 20, 2002Date of Patent: September 1, 2009Assignee: Nortel Networks LimitedInventors: Goran Janevski, Hamid Syed, Bill Gage

Publication number: 20090185522Abstract: The present invention allows content to be delivered to a mobile terminal over different types of networks in order to efficiently use network resources. Content can be delivered using a select delivery method over a cellular network, a local wireless network, or a broadcast network. Within any of the networks, the content may be unicast to individual mobile terminals using individual content flows, multicast to a group of mobile terminals, or broadcast to any or all of the mobile terminals. Content can be multicast or broadcast to mobile terminals via different ones of the disparate networks. During a content flow, the network through which the content flow is delivered may be changed to allow the mobile terminal to receive the content through a different network. Further, the delivery method used to deliver the content may dynamically change as the number of mobile terminals receiving or requesting the content changes.Type: ApplicationFiled: December 23, 2005Publication date: July 23, 2009Applicant: NORTEL NETWORKS LIMITEDInventors: Shalini Periyalwar, Bill Gage

Publication number: 20080285507Abstract: The present invention provides a scheduling technique that allows individual nodes in a wireless communication network to independently determine their own communication schedules. The communication nodes in the wireless communication network are associated with one or more compatible communication nodes through substantially non-contending communication links, wherein the communication links within a group of compatible communication nodes are substantially non-interfering. Each node will exchange scheduling information with the various compatible communication nodes, and determine the communication schedule for future communications with those compatible communication nodes. This communication schedule may dictate when information is received from or sent to a compatible communication node during a given transmission opportunity.Type: ApplicationFiled: April 28, 2005Publication date: November 20, 2008Applicant: NORTEL NETWORKS LIMITEDInventors: Biswaroop Mukherjee, Bill Gage, Jerry Chow

Publication number: 20080268907Abstract: The present invention provides conversion between SDUs transmitted between a central network controller and base stations and PDUs transmitted between the base stations and mobile terminals. For downlink communications, SDUs are transmitted from the central network controller and forwarded to the base stations in an active set. One base station will break down the SDUs to create PDUs to transmit to the mobile terminal. For uplink communications, the base station will receive PDUs from the mobile terminal, create SDUs from the PDUs, and transmit the SDUs to the central network controller. During switching events, continuity information received from a previously serving base station is processed by the mobile terminal and used to create continuity information to send to the currently serving base station and used to determine the appropriate PDU from which to start transmissions to the mobile terminal after the switching event.Type: ApplicationFiled: June 3, 2005Publication date: October 30, 2008Applicant: NORTEL NETWORKS LIMITEDInventors: Gamini Senarath, Shalini Periyalwar, Hang Zhang, Bill Gage, Mo-Han Fong

Patent number: 6859440Abstract: A technique for prioritization of access and paging in cellular communications systems. In the downlink direction, where a single Paging Channel is configured, a plurality of queues are created corresponding to individual services or groups of services with the same priority. Page attempts are assigned to the appropriate queue according to a pre-determined service-to-queue mapping. Pages from the queues are sent on the Paging Channel in accordance with a pre-determined dequeuing algorithm. Where multiple Paging Channels are used, page attempts are assigned to the appropriate Paging Channel according to a pre-determined service-to-Paging Channel mapping. In the uplink direction, where a single Access Channel is configured, each mobile station includes in the Access Message a parameter representing the number of consecutive unsuccessful access attempts which have been initiated by the mobile station.Type: GrantFiled: June 13, 2000Date of Patent: February 22, 2005Assignee: Nortel Networks LimitedInventors: Jagdish V.
