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:
The present invention provides a method and system for handoff control in a wireless communication network. In an embodiment, a method for handoff control in an IP based wireless communication network, comprising (i) monitoring and obtaining movement information of a moving mobile node (ii) predicting the next point of network attachment for the client mobile node, and (iii) performing the handoff operation before the mobile node moves to a new location corresponding to next point of network attachment, wherein the interruption time during the handoff is substantially minimum.
Abstract:
The present invention relates to a method of maintaining mobile connectivity in a mixed protocol access environment and more particularly the present invention relates to a method of maintaining mobile IPv6 connectivity when a mobile node moves from one point to another by preventing the mobile node from attaching to an IPv4 network. The present invention includes a method by which a mobile IPv6 enabled MN would become intelligent enough to avoid other protocols. The present invention is also designed to restrict the mobility of the MN to be within the IPv6 domain. The present invention provides a model for Internet Service Providers (ISPs) who are interested in deploying mobile IPv6 and who do not want interference from existing IPv4 infrastructure. The present invention is also designed for mobility within an only IPv6 enabled network or it can also be used to move within an only IPv4 enabled network or to move between a selected list of APs.
