Abstract: Interface device for interfacing between a PLMN network and a non-PLMN network, the PLMN network being configured to recognize cellular base stations as nodes thereof through which to mediate connections to cellular mobile devices, the non-PLMN networks each comprising a plurality of access points for mediating connections to network compatible mobile devices, and for which the network compatible mobile devices are not required to be cellular devices. The interface device is configured as a node of the PLMN network to appear to the PLMN network as a standard cellular base station, and comprises functionality to make non-cellular devices connecting to the non-PLMN network and attempting to access the PLMN network through the non-PLMN network appear as cellular devices to the PLMN network.

Abstract: The present invention provides a method and a system for handling content requests initiated by mobile wireless devices or content providers servers, implemented within a proxy server. Said method and system comprise of the steps: analyzing request type according to predefined business logic rules; identifying the relevant backend information server resources required for executing said request; connecting to the respective information servers; requesting and receiving the relevant information form the respective information servers; and forwarding the received information to content provider server.

Abstract: The present invention discloses a new method for identifying current content service visited by a mobile device user within a content server through a cellular network. According to this method the received content from the content provider server is parsed for identifying embedded hyperlinks and respective link titles. The parsed content is analyzed for identifying chosen hyperlinks of previous received content, recording thereof and identifying mobile device location within content server site according to the sequence of at least two successive hyperlinks titles.

Abstract: The present invention is a method and system of load balancing in a group of one or more servers connected to one or more subnetworks. Two or more independent servers are bound into a group, with one of the servers elected to serve as a leader. The leader acts as a load balancer for the group while the remaining servers act as slaves. This functionality eliminates the need for one or more dedicated load balancing devices and lowers the hardware requirements necessary for performing such load balancing.

Abstract: A multiple entity gateway for supporting cellular authentication from a non-cellular network, the gateway comprising a plurality of entities each located at a different one of a plurality of secure zones and having at least one gap between said entities across said secure zones, said gateway being configured to predefine communication signals allowed across said gap between said entities, thereby to filter out non-allowed signals, and provide secure cellular authentication for a communication originating from said non-cellular network. The gateway allows cellular users to connect to a cellular network via a wireless local area network such as a hotspot, use the services of the cellular network, the Internet and the hotspot at will, and be securely authenticated and charged through the cellular infrastructure.

Abstract: VPN tunnels are used to connect remote equipment to corporate intranets to create private connections over an ordinarily public network. Problems arise when multiple VPNs are being managed and when the connections exist of specific network segments, such as but not limited to wireless, satellite, cellular, and fiber optics. The disclosed invention allows the VPN tunnel to be broken and a Manipulated VPN to be established in the break. The Manipulated VPN allows for an improvement in efficiency in that manipulation equipment located at each side of the VPN break can emulate the destination equipment and thus, speed the data transfer. To accommodate the use of private IP addresses in this environment, bits of the time to live field are utilized to represent the particular VPN in which a destination private IP address resides.

Abstract: The communication between a remote email or application program and the server to which it interfaces, such as a mailbox exchange server, is improved. The present invention operates by tricking or controlling the application program in such away that the application program operates as thought it is on-line although in actuality it is off-line. This is accomplished by spoofing the application program and as a result, the application program operates off-line but the user has on-line type experience. More specifically, the present invention replaces the MAPI/RPC as the transport provider while the user is operating the application program in an off-line mode. The data transfer between the email application program and the email server is handled by the present invention in the background. On the server end of the connection, the present invention operates to spoof the server and thus causes the server to operate as though the remote customer is an interactive user presently connected to the domain.

Abstract: A method for proposing at least one transmission rate change including calculating a plurality of latency values, computing at least one derivative-based proposed change from the plurality of latency values, and proposing a rate change selected from the at least one derivative-based proposed change. Also provided is a system including a rate controller controlling the transmission rate of data between two stations over a network and a rate reporter in communication with the rate controller.

Abstract: A technique for downloading multiple objects from at least one server in an accelerated manner. Typically, in a TCP/IP environment, a client is limited in the number of sockets that can be opened for a single server. A spoofer (410) is utilized to intercept traffic between the server and the client and modify the traffic so that from the client's perspective, it appears as though objects from a single server are actually being sourced from multiple servers. Thus, the client is able to open additional sockets to receive objects from the server thereby allowing for a parallel download of the objects. This greatly reduces the amount of time necessary to download the objects.

Abstract: The transmission of image data through a network or other transmission medium is bandwidth intensive. To help reduce the amount of bandwidth utilized for the transmission of image data, compression algorithms are used. However, even once compressed, if a large amount of image data is being transferred, such as in a multimode network that shares graphic intensive information (i.e., the world wide web) bandwidth can be at a premium. The present invention provides a technique for receiving multiple image files from multiple sources and applying further compression, or recompression to help alleviate the bandwidth constraints. The present invention operates to further compress image files on-the-fly so that processing delays for the retransmission of the image files are limited. To effectuate the on-the-fly re-compression, image structures to indicate the status of re-compressing the various image files are maintained.

Abstract: The present invention provides a protocol and associated method for enhancing the throughput and response time performance of Transmission Control Protocol/Internet Protocol (TCP/IP) applications and services in Internet and Intranet environments that use the TCP/IP protocol suite, e.g., HTTP Internet browsers, HTTP servers, FTP servers, etc. The protocol of the present invention, termed Communication Enhancement Protocol (CEP), comprises a flow control method that functions to maximize the performance of IP communication links. The CEP is positioned in either Transport Layer 4 or Session Layer 5 of the OSI communications protocol stack. The CEP of the present invention optimizes the interactions between transport protocols and applications by utilizing novel flow control algorithms so as to reduce overhead and the use of the server's resources. Using the CEP of the present invention, data throughput and response time up to 2.5 times as fast as compared with conventional communication protocols.
