COMMUNICATION SYSTEM, CONTROL DEVICE, ROUTER USING NETWORK BASE IP MOBILITY PROTOCOL AND COMMUNICATION METHOD THEREOF

When a packet is delivered between LMA (3) and MN (1), routing is appropriately performed by adding an option header which can distinguish the MN (1) between routers (MAG) (2, 4) positioned between the LMA (3) and the MN (1). Moreover, when the MN (1) has moved, buffer transfer from the source MAGa (2) to the destination MAGb (4) is also performed by adding an option header for delivery to the MN (1). Thus, if the MN has moved when a packet is compressed by a mobile terminal (MN) or a control device (LMA) servicing as a compressor and a decompressor in the network base IP mobility protocol, it is possible to perform a fast handover so as to save the last one hop band which is the narrowest band.

Access router device, mobility control system, and mobility control method

In a network configuration in which a mobility control node is placed in the network, a packet is forwarded from a communication partner to the mobility control node by a basic IP mobility protocol for supporting movement in a local network managed by the mobility control node, a movement of a mobile terminal device across local networks formed by mobility control nodes is achieved without adding a function to the mobile terminal device. A mobility control node to be provided to the mobile terminal device is identified by a trigger reporting a movement has been performed to the network from the mobile terminal device, and, in the case of HO across between mobility control nodes, network information before the movement is reported instead of network information to be originally reported. Thus, the mobile terminal device determines that the movement is in the same network and can continue communication without performing an address generation procedure.

In an embodiment, when a device is leaving the air interface range of its home access point, it establishes a connection with an intermediary access point. In an embodiment, the communications from the network are directed to the original access point using the original IP address for the device, and forwarded to the device via the intermediary access point. Communications from the device are routed through the intermediary access point and then either directly to the network, or else through the home access point to the network. The IP address handoff is repeated between intermediary access points until the device either returns to the home access point or ceases communication with the network.

Parameterized recursive network architecture with topological addressing

A digital data communications network that supports efficient, scalable routing of data and use of network resources by combining a recursive division of the network into hierarchical sub-networks with repeating parameterized general purpose link communication protocols and an addressing methodology that reflects the physical structure of the underlying network hardware. The sub-division of the network enhances security by reducing the amount of the network visible to an attack and by insulating the network hardware itself from attack. The fixed bandwidth range at each sub-network level allows quality of service to be assured and controlled. The routing of data is aided by a topological addressing scheme that allows data packets to be forwarded towards their destination based on only local knowledge of the network structure, with automatic support for mobility and multicasting. The repeating structures in the network greatly simplify network management and reduce the effort to engineer new network capabilities

Seamless mobility in wireless networks

AP's associated with a communication network and any wireless devices desiring contact, operated according to a protocol in which each wireless device selects AP's with which to communicate. A system coordinator causes the AP's to operate so as to guide each wireless device to an AP selected by the system coordinator. This has the effect that, notwithstanding that the protocol involves having the wireless device make the selection of AP, functionally, the AP's make the selection for it. In a 1st technique, multiple AP's share an identifier, with the system coordinator directing one particular AP to respond to the wireless device, thus appearing to wireless devices as a “personal cell”. In a 2nd technique, AP's each maintain identifiers substantially unique to each wireless device, with the system coordinator directing only one particular AP to maintain any particular wireless device's identifier, thus appearing to wireless devices as a “personal AP”.

Route configuration in switching networks with mobile terminals

Predictive and nomadic roaming of wireless clients across different network subnets

Wireless access points detect neighboring wireless access points in different subnets. Upon connecting with a wireless client, a wireless access point determines predictive roaming information for the wireless client. Predictive roaming information identifies the wireless client; its home network subnet; and includes connection information associated with the wireless client. The wireless access point forwards the predictive roaming information associated with a wireless client to neighboring wireless access points while the wireless client is still connected with the wireless access point. Neighboring wireless access points store received predictive roaming information. Upon connecting with a wireless client, a neighboring wireless access point determines if the wireless client matches the stored predictive roaming information. If so, the neighboring wireless access point uses the predictive roaming information to quickly connect with the wireless client and to establish a tunnel to redirect network traffic associated with the wireless client through to its home subnet.

Local mobility anchor relocation and route optimization during handover of a mobile node to another network area

The invention relates to a method for managing the mobility of a mobile node that moves to a different network, but keeps the same IP address. It is proposed to perform route optimization by a Proxy MIP agent on behalf of the MN, thereby shortening the data-path while allowing network-based mobility.

Routing in a data communication network

A method of supporting mobility (400, 500) in an Internet Protocol (IP)-based data network. The method comprises the steps of generating a first stateful IP autoconfiguration message at a mobile node, whereby the message includes an address capable of use for routing maintenance. The mobile node transmits, the generated message to a first access node (240), which incorporates its address and forwards the message to a dynamic host configuration protocol (DHCP) Server.

Pmipv6 mag restoration

A mechanism to permit an LMA to perform some specific handling once MAG restart is detected is disclosed. If a MAG restart is detected by the LMA, the LMA preferably will not release all corresponding binding in its cache. The LMA may select an alternative MAG which is servicing the same. Then the LMA can send a mobility message to the selected MAG. The mobility message can be triggered by the restart detection or by the received downlink data on one or more valid binding. The mobility message can contains all UE identity that has a valid binding in the LMA and the restarted MAG.

Traffic offload in multi-access mobile communication systems supporting network-based IP mobility

Communication system using network base ip mobility protocol, control device, router, and its communication method

Provided are a communication system, a control device, a router, and its communication method which eliminates a packet loss in handover and effectively release router resource in a network base IP mobility protocol which can be moved without requiring a mobile terminal to mount a special protocol. When a mobile terminal MN1 moves, a router and a mobile access gateway (MAG) (b3) of the movement destination which has received a router solicitation from MN1 transmits a location registration to a control device and a local mobility anchor (LMA) (4). When the LMA4 judges that a handover is present, LMA4 instructs the router movement source and MAGa2 or MAGb3 to transfer buffer from MAGa2 to MAGb3.

Lightweight mobility architecture

Local mobility management in mobile Internet protocol network

The invention relates to mobility management in a mobile Internet protocol network. The network comprises a local mobility domain access router and a wireless access point operationally connected to the local mobility domain router, where the wireless access point is proxying a mobile node. Data packets destined to the mobile node and entering the local mobility domain router hold a proxy care-of address assigned to the mobile node as a routing address. The proxy care-of address is replaced with a local address assigned to the wireless access point, where the local address is invisible to the mobile node. With the procedure of the invention, the local mobility domain router acts as a wireless attachment point for the mobile node, thus decreasing signalling over the air interface when the mobile node moves in the network.

Telecommunications routing

In a mobile packet network, data is transmitted concurrently from two base stations to a mobile node, for example during handover.

Seamless roaming among multiple networks

The present invention relates to wireless communication systems involving multiple local area networks. A communication system according to the present invention includes a plurality of local area networks (LANs). Each of the LANs includes: a network backbone; and at least one access point coupled to the network backbone which, when a mobile terminal is registered to the access point, enables the mobile terminal to communicate wirelessly with a device on the network backbone via the at least one access point. When the mobile terminal is registered to at least one access point in one of the plurality of LANs the mobile terminal is assigned a first network address, and when the mobile terminal is registered to at least one access point in another of the plurality of LANs the mobile terminal is assigned a second network address in place of the first network address, the second network address being different from the first network address. The mobile communication system also includes a system backbone interconnecting the plurality of LANs for permitting communications between the plurality of LANs. Furthermore, the system includes a gateway controller, operatively coupled to one of the plurality of LANs, for serving as an intermediary for communications between the mobile terminal and a device on one of the system backbones in order that in the event the mobile terminal is assigned a different network address by virtue of registering with an access point in another of the LANs, the device is able to maintain communications with the mobile terminal without requiring knowledge of a change in the network address of the mobile terminal.

Global virtual local area network for voice communication sessions in a wireless local area network

A communication network has a first wireless access point (AP) in a first subnet segment and a second wireless AP in a second subnet segment, and provides a virtual local area network (VLAN) which spans the first and the second subnet segments. A mobile device associates with the first wireless AP using a first extended set service identifier (ESSID). In response to identifying a request to establish a communication session, the mobile device reassociates with the first wireless AP using a second ESSID, for accessing the VLAN to establish and maintain the communication session.
