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:
There is provided a method that allows adding complex dependency logic to an existing database for self organized system without having to modify the underlying structure of the database. The present invention provides a way to flexibly handle record state transitions by using an event model. In other embodiment of the present invention an event meta-model is instantiated to represent a number of different event models and the corresponding dependencies that inter-relate them. Hash algorithm approach may be implemented for building the self-organized communication system database.
Abstract:
A system for communication in a wireless backhaul environment having wireless mesh networks connected in part to the Internet comprising a communication topology. The communication topology comprises communication cells each having a relay station and mobile nodes communicating to each other using 802.16j wireless technology wherein the cells are arranged in a grid fabric within the communication topology.
Abstract:
A method (10) for embedded mesh path management in a wireless multi-hop relay network comprising a base station, at least one relay station and a mobile station, the method comprising assigning a connection identifier (CID) by said base station (12) as a super-ordinate station to said at least one relay station (13) as subordinate station with specified routing path of the connection based on said assigned CID, changing the unique assigned identifier of one of the relay stations upon connection to the another one of the at least one relay stations (21), and performing data transmission to said relay stations which are connected in mesh topology in accordance to the routing information embedded in said assigned connection identifier.

Abstract:
A method of scheduling and forwarding data messages to a plurality of relay stations (RS) from a base station (BS) in mesh topology in uplink and downlink direction is provided, the method includes the steps of detecting a neighboring RS by sending a measurement request message, broadcasting the neighboring RS information to a plurality of RS within radio range, checking packet destination for a plurality of RS, performing path calculation for a designated RS based on a shortest path calculation and forwarding traffic to RS from the BS.
Abstract:
A centralized VoIP network system (10) comprises a plurality of endpoints (12a-12f) and a SIP server (11) coupled to said endpoints (12a-12f) in said network (10), said server (11) operable to determine the codec bitrate from the network bandwidth availability based on the predetermined threshold values.
Abstract:
A method of distributing data traffic to predetermined destinations in wireless multi hop networks is provided, the method includes the steps of receiving data traffic from a source, breaking out received traffic and redistributing traffic to predetermined destinations which are configurable as recorded in a mapping table.
