    Abstract: An interleaved wireless mesh network is described where each mesh node always has at least two radios that have access to at least two parallel meshes, and where a packet stream may utilize either or both of these parallel meshes for any given hop, using the parallel (physical) meshes as a single (logical) mesh. Here, two sequentially adjacent packets in a particular packet stream may travel on the same mesh or on different meshes for any given hop, thereby enabling the performance of a specific sequential packet stream to be doubled. Dynamic frequency selection (DFS) operations can be performed by the parallel meshes upon sensing radar interference on a channel used by either mesh. While one mesh is performing the DFS, packets may continue to be propagated on the alternative mesh, thereby enabling continuous and uninterrupted data flow throughout the network.

The present invention is utilized in a network providing Voice over Internet Protocol (VOIP) by a service provider to a user using a VoIP phone. When a user originates an emergency 911 call from the VoIP phone, a gateway communicating with a digital class 5 switch within the network, analyzes the signaling packets received from the VoIP phone and determines if a VoIP call originated by the user is an emergency 911 call. If the call is an emergency 911 call, the gateway will also determine if the VoIP call originates from the user's listed location provided to the service provider. If the call is not originated from the listed home location, the call is handled in a manner to prevent sending emergency response teams to the wrong location. The call may be processed and transferred to a specialized emergency call center which is informed that the call is not originating from the user's listed location.

    Abstract: In a network which includes at least a transmission-side apparatus having a plurality of logical plugs and a reception-side apparatus having a plurality of logical plugs, correspondence between transmission-side logical plugs (e.g., P2 to P4) and reception-side logical plugs (e.g., P4 to P6) is established. The reception-side apparatus stores therein plug data Splug (P2) representing one of the transmission-side logical plugs, plug data Dplug representing a logical plug corresponding to the plug data Splug, among the plurality of reception-side logical plugs, and connection number Nconn representing the number of logical plugs to be connected. The transmission-side apparatus adds to control data a plug number PluNO (P3) representing the logical plug which has output the control data and transmits the control data.

    Abstract: A broadband service is provided by allocating air interface resources in a wireless network that conforms to the 1xEV-DO standard. The air interface resources are characterized by various quality of service (QoS) parameters, such as bandwidth, packet priority and error rate. Packetized information is transmitted in data flows between a base station and cell phones. A particular QoS level is reserved for each of the data flows that support the broadband service. An operating system on a cell phone monitors one data flow as well as another data flow in the opposite direction. When the base station runs out of an air interface resource, the base station suspends the QoS reservation of a data flow. The operating system determines that the QoS reservation in one direction has been suspended and sends an unsolicited message to the base station releasing the QoS reservation in the opposite direction, thereby conserving network resources.

    Abstract: A technique for reliable multicast involves identifying a client as an acknowledger of a wireless multicast packet, and having the acknowledger acknowledge receipt of the multicast packet. An example of a method according to the technique may include receiving a multicast packet, selecting a client associated with a destination of the multicast packet, identifying the client in the multicast packet, forwarding the multicast packet to wireless, and retrying forwarding the multicast packet with the client identified in the multicast packet if no acknowledgement is received from the client. An example of a system according to the technique may include a means for identifying a client, a means for putting the client mac in the header of a multicast packet, a means for sending the multicast packet with the client mac to a wireless multicast destination, and a means for receiving acknowledgement from the client associated with the client mac.

    Abstract: A terminal hand-off apparatus in a wireless broadband Internet system and a terminal hand-off method in the system includes a connection processor and a hand-off processor. The connection processor predicts a movement direction using a current position of the terminal in communication with a counterpart terminal using a predetermined Internet Protocol (IP) address, and requests an IP address to be assigned upon entering a coverage area of at least one of a plurality of Radio Access Stations (RASs) located near the predicted movement direction. The hand-off processor transmits at least one IP address assigned from the RAS whose coverage area has been entered to the counterpart terminal, and requests the counterpart terminal to transmit data to the IP address assigned by the RAS upon hand-off to one of the plurality of RASs assigning the at least one IP address.

  • Publication number: 20070160049
    Abstract: A communication system provides for an expedited Mobile Internet Protocol handoff by allowing a mobile station that is engaged in a communication session with a first access network to obtain Internet Protocol connectivity information associated with a second access network via the first access network. A tunnel is then established between the mobile station and the second access network via the first access network based on the Internet Protocol connectivity information and the mobile station obtains Internet Protocol configuration parameters from the second access network via the established tunnel. By obtaining the Internet Protocol configuration parameters associated with the second access network via the first access network instead of waiting until an air interface connection has been established with the second access network, the mobile station may be more expeditiously handed off to the second access network in the event that such a handoff determination is made.
