In one embodiment, the present invention is a method and apparatus for DNS pre-fetching for multiple clients. In one embodiment, all packets coming into or going out of a local network are scanned for application protocol, domain names, and / or other information. If pre-defined criteria indicate that the network is interested in a particular domain name, a DNS lookup is performed and the corresponding IP address is cached by the local DNS server. The local DNS server is thereby able to quickly respond to future requests for the cached domain name. Moreover, because the IP address is cached at the local DNS server, any client connected to the local DNS server on the local network can request the cached domain name from the local DNS server and be quickly connected to the indicated domain name.

A system and method for providing Value-Added Services (VAS) in an integrated telecommunications network having a packet-switched network portion (PSN) operable with Session Initiation Protocol (SIP). The integrated telecommunications network includes a SIPext SSP server, a trigger server, and a service node having a Service Logic Program (SLP) that is operable with Intelligent Network Application Protocol (INAP). The SIPext SSP and service nodes are provided with the capability to communicate using SIP-compliant messaging. New header fields are provided that specify operations to be performed by the service node with respect to a service. INAP service parametric data is also provided in the header fields in a sequential form. When a call is received in the SIPext SSP server for a user having a subscription for a VAS, it queries the user profile stored in the trigger server. If the user is subscribed for a service, a SIP request message is formulated based on the user profile, wherein appropriate headers are populated with relevant parametric information and call context data. The service node launches the SLP based on the information provided in the request message and sends a SIP response message to the SIPext SSP server with an instruction concerning the provisioning of the VAS. The SIPext SSP server, thereafter, takes an appropriate action based on the response message and any parametric information contained therein.

The invention relates to methods for providing a network element 5 of a communications network with data, in particular HSDPA related data. In order to enable the transmission of user data, it is proposed that a controller 4 of the network uses a dedicated frame structure for assembling frames with said user data. The frames can then be transmitted from the controller 4 via an interface to the network element 5. In order to enable the transmission of control parameters, it is further proposed that an interface application protocol is employed which allows the controller 4 to add control parameters to control messages transmitted from the controller 4 to a network element 5 via the interface.

System and Method for detecting anomalous network application behavior. Network traffic between at least one client and one or more servers may be monitored. The client and the one or more servers may communicate using one or more application protocols. The network traffic may be analyzed at the application-protocol level to determine anomalous network application behavior. Analyzing the network traffic may include determining, for one or more communications involving the client, if the client has previously stored or received an identifier corresponding to the one or more communications. If no such identifier has been observed in a previous communication, then the one or more communications involving the client may be determined to be anomalous. A network monitoring device may perform one or more of the network monitoring, the information extraction, or the information analysis.

A common communication language that can address all the applications running in a multitude of set top boxes (STBs) or client devices and application servers. The present invention, DATP protocol encapsulates a meta language that provides a generic portable communication application programmer interface that requires light processor utilization and is well-suited for a typical STB possessing limited processing power. DATP requires relatively few processing cycles compared to typical Internet communication protocols. DATP reduces the overhead of the communication protocol handler at the STB and makes the communication protocol handler common for all STBs applications. The preferred DATP protocol is portable for all STBs since it is written in a native language that interfaces with the underlying operating system of the STB. A SGW (SGW) performs as a DATP server. The SGW translates between DATP messages and standard communication protocols. SGW enables SP clients at STBs utilizing DATP to communicate with service applications using a variety of communication protocols. A content converter is provided to convert standard Web content into content suitable for display on a client viewing device, e.g., a TV.

A system, apparatus, and method are directed to converting from a use of a HTTPS connection to a tunnel connection while maintaining an underlying connection between a client and a server. An HTTPS connection is employed to establish a network connection between a client device and a network device. A gateway is selected to receive a request from the client device. In one embodiment, selecting may comprise using load-balancing, cookie-persistence, or the like. Subsequently, the HTTPS connection is transitioned to another application layer communication protocol connection. Transitioning may comprise converting from a use of a first protocol stack configured to process a HTTP connection to a second protocol stack configured to process a non-HTTP based application protocol connection, and establishing a tunnel between the client device and a server through the selected gateway.

A system and unified method of address resolution in an IP-based network. A Resolver determines whether an input address is a URL / URI, and if so, extracts a domain name. If the input address is an E.164 number, the Resolver converts the E.164 number into a domain name in ENUM format. The Resolver then sends a domain name query to a DNS which, if able, returns the IP address for either a Global MGCF or a destination server along with a supported Application protocol. If the DNS is unable to perform the translation, or the Application protocol returned is not supported by the requesting application, the Resolver sends a domain name query to an extended Location Server (LS) to obtain an IP address of a gateway function capable of interfacing with the destination server.

If no such identifier has been observed in a previous communication, then the one or more communications involving the client may be determined to be anomalous. A network monitoring device may perform one or more of the network monitoring, the information extraction, or the information analysis.

A Voice over IP network having multiple signaling message transfer nodes (e.g., call agents, signaling gateways), communicate with switched circuit network nodes using a single point code. A signaling gateway, upon receiving an SS7 signaling message specifying a destination point code corresponding to its provisioned point code and carrying a signaling application protocol message, selects a destination call agent based on the originating point code in the SS7 signaling message and independent of the destination point code. The signaling gateway selectively outputs to the selected destination call agent an IP-based message carrying the signaling application protocol message according to a prescribed IP-based signaling message transport protocol, based on a determined availability of the selected destination call agent. The signaling gateway uses the User Part Unavailable message to inform the originating PSTN switch that the selected destination call agent is unavailable.

The present invention presents techniques for transmitting application specific instruction between a host and a memory card. The commands for the application specific protocol are embedded along with a signature in the data portion of a transmission protocol that is used to communicate between the host the memory card. This allows for the transmission of application specific commands that lack a corresponding command in the transmission protocol to still be transmitted in that protocol. The method can be implemented on the host side either at the device driver level or the file level. In order to implement a read command in the application specific protocol, a write command in the first protocol with an embedded read command is first sent to a logical address, followed by a second read command to the same logical address.
