20090274080 | Method for Unifying Operations of Boards by Using Logical Addresses Thereof - The present invention relates to a method or unifying operations of a plurality of boards in a CDMA communication system by using logical addresses of the boards. Conventionally, since a board with a physical slot ID must be attached to a slot of the system corresponding to the physical slot ID, the board cannot be recognized by the system if it is attached to another slot of the system. In the present invention, a board is attached to a slot of the system on the basis of a logical address of the board, which is stored in a board configuration information. According to the present invention, since a board can be attached to any slot of the system regardless of the physical slot ID of the board, the boards can be easily managed. | 11-05-2009 |

A transaction routing system operating on the method is also provided. | 10-01-2009 |
20090132715 | SYSTEM AND METHOD FOR CONDUCTING SECURE IP TRANSACTION SESSIONS WITH PERSISTENCE - A method for providing a persistent network session is disclosed. The method includes conducting a first session between a terminal and a server via a communication gateway. The first session includes a session between the communication gateway and the server. The method also includes issuing a notification to the communication gateway to continue a session between the terminal and the communication gateway upon closure of the first session. | 05-21-2009 |
20090119410 | MIDDLEWARE ARCHITECTURE FOR IPTV MULTIMEDIA STREAMING - A media content distribution system for distributed multimedia streaming communicates over a network and incorporates multiple independent media stations, each having a media director for control and a number of media engines for storage, retrieval and streaming of media content. A middleware system employing a execution engine for service platform middleware and a presentation engine for terminal middleware is provided for flexible interfacing with network transport and home network elements respectively and the IPTV applications supported. | 05-07-2009 |
20090100188 | METHOD AND SYSTEM FOR CLUSTER-WIDE PREDICTIVE AND SELECTIVE CACHING IN SCALABLE IPTV SYSTEMS - A method for caching of stream data is accomplished by assigning for each video segment in the system a likelihood rating of future showing and then determining for each node that contains a copy of the segment a second likelihood value that reflecting a probability that the node will be used to serve streams for the segment. The future cost value of a segment copy is then predicted and preload orders are issued to nodes for segments with the per-copy likelihood above a predefined threshold. | 04-16-2009 |
20090019493 | CACHE AFFILIATION IN IPTV EPG SERVER CLUSTERING - An EPG service architecture incorporates multiple EPG servers connected in a cluster. An active dispatcher is associated with at least one EPG server and multiple standby dispatchers are associated with the cluster. A plurality of STBs interfaced with the EPG server cluster issue requests for EPG service for which the active dispatcher employs an affiliation table as a portion of the cache for redirecting each request to a specific one of the EPG servers affiliated with the STB issuing the request. The active dispatcher multicasts the affiliation table to the multiple standby dispatchers for synchronization. | 01-15-2009 |
20090019161 | HYBRID EPG SERVER WITH SERVICE DISPATCHER TO BUILD A DISPATCHER REDUNDANCY CHAIN IN CLUSTERED IPTV EPG SERVICE - An EPG service architecture incorporates multiple EPG servers connected in a cluster with each EPG server having an EPG service module and a dispatcher. Each dispatcher has the capability for state determination as an active or standby dispatcher. A plurality of STBs interface with the EPG server cluster and issue requests for EPG service which are routed by the active dispatcher. The routing is accomplished by redirection of the request to an EPG service module selected from the multiple EPG servers in the cluster. Each EPG service module includes the capability for service connection to the STB upon receiving the redirection from the active dispatcher. Upon a determination that the current active dispatcher is not operating, the standby dispatchers vote for a replacement which then assumes the active dispatcher role. | 01-15-2009 |
20080319840 | METHOD AND APPARATUS FOR REAL-TIME TV ADVERTISEMENT AUCTION IN A TV-OVER-IP ENVIRONMENT - A system for real time auctioning of advertising timeslots for live TV transmission over IP networks incorates settop boxes interconnected to a searver to provide real time viewing statistics to an advertising management system which also receives subscriber information from a subscriber management system which also management system determines demographics responsive to the subscriber information and viewing statistics and publishes advertising timeslot information and the determined demongraphics. A management terminal is employed for creating user accounts, providing access information to users, inspecting and approving advertisements responsive to input the advertisements from the users. Bid parameters are defined using the management terminal and the publication by the system to the users is responsive to the bid parameters. User terminals are provided for uploading advertisements to the advertising management system and the advertising management system further assigns unique identification to the uploaded advertisements. The user terminals upload advertising parameters, receive the published time slots and demographics and submit bids to the advertising management system. The advertising management system receives the bids and inserts predefined advertisements responsive to a winning bid. | 12-25-2008 |
20080318556 | IP BASED LAWFUL INTERCEPTION ON LEGACY EQUIPMENT - A system and method for lawful intercept of call content receives subscriber information as a lawful intercept target and issues commands to initiate bridge endpoints in a lawful intercept media router (LIR) for transmitting RTP data. The LIR receives the bridge endpoint commands and provides duplicates of RTP data packets associated with the subscriber transmitted through the endpoint for transmission to a delivery function. | 12-25-2008 |
20080291869 | Routing Method for Mobile Wireless Nodes Having Overlapping Internet Protocol Home Addresses - In mobile IP wireless data networking, methods are described for correctly routing packets through a foreign agent to or from wireless nodes where the wireless nodes have the same home network IP address. Instead of using normal IP routing, the foreign agent uniquely identifies the wireless node's home network IP address and home agent IP address with a PPP link address associated with a PPP link between the foreign agent and the wireless node. This association between PPP link addresses, home agent IP addresses, and home network IP addresses, is preferably implemented in software as a table stored in the foreign agent. The routing of packets through the foreign agent to the mobile nodes is performed by reference to the table. The table allows the foreign agent to correctly and efficiently route packets in the situation where multiple wireless nodes are registered with the foreign agent, but more than one of the wireless nodes have the same home network IP address. | 11-27-2008 |
20080225767 | Device for Implementing a RNC Using LVDS - A device for implementing a RNC is provided with an interface interfacing between sub-systems of a system for the RNC.

In the device of the present invention, the data transmission between the sub-systems is performed in the form of LVDS signals converted from ATM UTOPIA data. Further, the active pass link of two interfaces is switched, while outputs are transmitted from the active pass link to two interfaces. | 09-18-2008 |
20080220754 | IP BASED LAWFUL INTERCEPTION AT THE SOURCE - A system and method for lawful intercept of call content incorporates a control element receiving subscriber information as a lawful intercept target and issuing a media forking command to a media transfer element transmitting RTP data. The media transfer element receives the media forking command and provides duplicates of RTP data packets associated with the subscriber transmitted through the media transfer element for transmission to a delivery function. The media forking command is an attribute in an SDP and includes definition of IP addresses for at least one delivery function. An acknowledgement of the forking command from the media transfer element to the control element is provided. | 09-11-2008 |
