20080304458 | Inter-Working of Networks - In a heterogeneous network environment comprising a plurality of first wireless networks and a second wireless network, said plurality of first wireless network utilizing a first wireless communication protocol and said second wireless network utilizing a second wireless communication protocol different to said first, a method of gathering data from said plurality of first wireless networks, which method comprises the steps of: electronically extracting a network identifier from at least one of said first wireless networks; transmitting said network identifier to a remote server; and said remote server compiling a database of network identifiers received from said plurality of first wireless networks, storing of said database facilitating inter-working between one or more of said plurality of first wireless networks and said second wireless network. | 12-11-2008 |
20090052423 | Systems and Methods for Improved Mobility and Quality of Service in a Wireless Network - For a mobile node visiting a packet-switched wireless access network, said access network using a tunnelling-type micro-mobility protocol and a Quality of Service (QoS) routing protocol to route packet data to and from said mobile node, and comprising an access router to which said mobile node may attach, a mobility agent and a gateway, a method of configuring said access network to route packet data toward said mobile node which method comprises the steps of: (a) receiving in said access network a handover indication of said mobile node or a login request therefrom; (b) in response to said handover indication or login request computing a QoS route for said mobile node, which QoS route is useable to route packets between said mobility agent and said mobile node; (c) performing step (b) at a location in said access network remote from said mobility agent; and (d) transmitting said QoS route and said handover indication or login request from said remote location toward said mobility agent; whereby upon receipt of data transmitted in step (d) said mobility agent may handle both mobility configuration and QoS route configuration for said mobile node as part of said network layer handover. | 02-26-2009 |
20090252200 | ELECTRONIC DATA COMMUNICATION SYSTEMS - A method of transmitting data across an electronic data communication system comprising a plurality of terminals that can send and receive data in the form of electromagnetic waves to and from at least one of the terminals, which method comprises the steps of: (a) identifying at least one control terminal, at least one target terminal and at least two relaying terminals from the plurality of terminals; and (b) using the control terminal to instruct the at least two relaying terminals to receive and relay data intended for the at least one target terminal, so that the at least one target terminal can receive data directly from at least one terminal and from the at least two relaying terminals, thereby increasing capacity of the system. | 10-08-2009 |
20090279434 | Packet-Switched Access Networks - In a packet-switched access network using a tunnelling-type micro-mobility protocol whereby packets are caused to flow through at least one mobility agent located in said access network, a method of reducing congestion at and/or in routers near said mobility agent, which method comprises the steps of causing packet traffic of a first class to use said tunnelling-type micro mobility protocol and packet traffic of a second class to use another mobility protocol, whereby packet traffic of said second class is routed across said access network away from said mobility agent. | 11-12-2009 |
20100150107 | Inter-Access Network Handover - In a wireless network environment comprising first and second packet-switched access networks, each access network using a tunnelling-type micro-mobility protocol and a Quality of Service (QoS) routing protocol to route packet data to and from mobile nodes attached thereto, and each access network comprising an access router to which a mobile node may attach, a mobility agent with which said mobile node may register and a gateway, a method of facilitating network layer handover of said mobile node from said first access network to said second access network, said mobile node registered in said first access network with a serving mobility agent, which method comprises the steps of: said mobile node receiving a router advertisement from said second access network, which router advertisement comprises a network-layer address of a target mobility agent in said second access network with which said mobile node may register; and said mobile node forwarding said network-layer address to said serving mobility agent, whereby said serving mobility agent may communicate with said target mobility agent to facilitate network-layer handover of said mobile node to said second access network. | 06-17-2010 |
20100150108 | Network Mobility - In a wireless network environment comprising a mobile router serving a moving network, said mobile router for attaching to a packet-switched access network that uses a micro-mobility protocol and a Quality of Service (QoS) protocol to route packet data to and from said mobile router, wherein said mobile router has a QoS aggregate requirement generated by nodes attached thereto, a method of handover of said mobile router to a mobility agent in said access network, which method comprises the steps of: (i) said mobile router sends a QoS request message to said mobility agent, which QoS request message comprises a QoS parameter representing said QoS aggregate; (ii) upon receipt by said mobility agent, said access network takes a QoS admission decision on the basis of said QoS parameter; and (iii) said mobility agent sends a QoS acknowledgement to said mobile router whereby said mobility agent informs said mobile router of the outcome of said QoS admission decision; characterized by the step of (iv) if said QoS admission decision is that said mobility agent cannot handle all of said QoS aggregate, said QoS acknowledgement comprises an identity of one or more alternative mobility agent that might meet at least a part of said QoS aggregate that will not be provided by said mobility agent. | 06-17-2010 |
20110019608 | METHOD AND SYSTEM FOR FREQUENCY RELAYING - A method of transmitting data across an electronic data communication system comprising a plurality of terminals that can send and receive data in the form of electromagnetic waves to and from at least one of the terminals, which method comprises the steps of: (a) identifying at least one control terminal, at least one target terminal and at least two relaying terminals from the plurality of terminals; and (b) using the control terminal to instruct the at least two relaying terminals to receive and relay data intended for the at least one target terminal, so that the at least one target terminal can receive data directly from at least one terminal and from the at least two relaying terminals, thereby increasing capacity of the system. | 01-27-2011 |
20140254560 | NETWORK MOBILITY - In a wireless network environment comprising a mobile router serving a moving network, said mobile router for attaching to a packet-switched access network that uses a micro-mobility protocol and a Quality of Service (QoS) protocol to route packet data to and from said mobile router, wherein said mobile router has a QoS aggregate requirement generated by nodes attached thereto, a method of handover of said mobile router to a mobility agent in said access network, which method comprises the steps of: (i) said mobile router sends a QoS request message to said mobility agent, which QoS request message comprises a QoS parameter representing said QoS aggregate; (ii) upon receipt by said mobility agent, said access network takes a QoS admission decision on the basis of said QoS parameter; and (iii) said mobility agent sends a QoS acknowledgement to said mobile router whereby said mobility agent informs said mobile router of the outcome of said QoS admission decision; characterized by the step of (iv) if said QoS admission decision is that said mobility agent cannot handle all of said QoS aggregate, said QoS acknowledgement comprises an identity of one or more alternative mobility agent that might meet at least a part of said QoS aggregate that will not be provided by said mobility agent. | 09-11-2014 |
