Abstract:
A method of providing a multicast service announcement using a hypertext transfer protocol for sending a service announcement from an announcement server to at least one receiving node, the receiving node communicating only with said announcement server to access said service announcement. The announcement server periodically checks for said signaling message from said sending node. The said hypertext transfer protocol announcement is able to communicate with a real-time transport protocol associated with multimedia streams.
Abstract:
A method (200) and system (100) for encapsulating multicast packets into unicast packets, the system comprises a TCP/TP communication stack having means for receiving a plurality of incoming multicast packets from an incoming wireless module (102), a first translation module (106) having means for translating the plurality of incoming multicast packets to a recognizable format for mapping, an intelligent hashing table (110) comprises means for storing a extracted subscriber IP address, a subscriber MAC address and a TTL period, a second translation module (114) comprises means for translating the unicast packets to a format recognizable for transmission, means for transmitting the unicast packets into an outgoing wireless module (116) and mapping modules comprises of a first mapping module (108) and a second mapping module (112). The mapping modules (108, 112) comprises the method of extracting the subscriber IP address, the subscriber MAC address and the TTL period from a plurality of incoming multicast packets (302), storing the subscriber IP address, the subscriber MAC address and the TTL period in an intelligent hashing table (304); encapsulating the plurality of incoming multicast packets into a plurality of unicast packets (306), forwarding the unicast packets for mapping (308) and multiplying the unicast packets in the presence of multiple subscribers (310).
Abstract:
A system (10) for power management with optimized connectivity in handoff of mobile device (11) between heterogeneous network (12, 13, 14) said mobile device (11) comprising a power management module which obtains power state information of said mobile device (11), and a network interface management module which includes a prioritized set of network interfaces (12, 13, 14) to enable said mobile device (11) to select for optimum quality of connection according to the power state of said mobile device (11).
Abstract:
The present invention relates to a system (100) and a method for facilitating mobile Internet Protocol (IP) communication. The system (100) comprises an IP address updating component (310) residing in a mobile destination terminal (30), an IP communication connecting component (320) residing in a transit terminal (20), an access requesting component (330) residing in a source terminal (10), and a session verifying component (340) residing in the mobile destination terminal. The system (100) and the method revolves around keeping track of the mobile destination terminal (30), keeping track of the communication session between the mobile destination terminal (30) and the source terminal (10). The system (100) and the method revolve around the authentication and mobility purposes.
Abstract:
The present invention relates to a system and method for differentiating backhaul traffic of wireless network. Accordingly, the present invention aims at introducing a queuing, scheduling and de-multiplexing mechanism coupled with virtual interfaces to provide dedicated and prioritized connectivity to backhaul traffic for multi tired wireless network system.
Abstract:
The present invention relates to a method and system for use in providing multiple gateways within a network. A plurality of border routers (100, 200, and 300) is added preferably in between the mobile router (150) of the respective network and foreign routers so as to enable consistent connection. The border routers, among others are (100, 200, 300) suitably configured to serve as proxy advertisers for foreign routers (500), and to send out notifications with respect to their active or inactive status to the mobile router (150) of the network so as to enable the mobile router (150) to select the preeminent border router (100, 200, 300) for forwarding packets within the network.
Abstract:
A method of optimizing the quality of multicast services over a wireless network by dynamically controlling a broadcast rate, comprising: suppressing an automatic rate fallback protocol so that a broadcast data rate is not limited to the base data rate; transmitting a multicast data stream from an access point to a plurality of nodes; detecting if there is any data loss in the said multicast data stream; and lowering the data rate for each node incrementally if there is any data loss, until the data loss reaches an acceptable level or until the said minimum rate is reached, whichever happens first.
