摘要： An enhanced frame relay access device (FRAD) capable of bidirectional interfacing between Signaling System No. 7 (SS7) protocol and Frame Relay protocol is utilized to economically transport SS7 signaling and link management information between SS7 networks via a Frame Relay protocol digital communications network. In an outgoing data transfer, the enhanced SS7 FRAD interface determines and eliminates redundant signaling unit information found in an SS7 data stream before packaging the essential information into a frame "payload" and introducing the frame into the Frame Relay network. For incoming data transfers, the SS7 FRAD extracts the frame payload data and regenerates the appropriate SS7 signaling units to maintain a continuous and synchronous data stream on the SS7 network. In the event communications with an SS7 facility is not possible (for example, an SS7 network or facility is down), the SS7 FRAD communicates its operational status to other SS7 FRADs by sending a proprietary coordination and status information frame across the Frame Relay network. A plurality of SS7 FRADs are configurable to provide multiple efficient links between different SS7 facilities over the Frame Relay network. In addition, each FRAD is individually customized to provide special functions such as encryption/decryption and data compression/decompression.

摘要： Methods and systems for identifying and mitigating telecommunications management message security threats are disclosed. A distributed security screening platform receives management messages from external sources. The distributed security screening platform identifies messages affecting the status of the same managed resource and applies a time-based security policy to these messages. If the messages are determined to violate the time-based security policy, a mitigating action is performed to protect the managed resource.

摘要： Methods, systems, and computer readable media for early media connection proxying are disclosed. According to one method, a call setup signaling message is received for establishing a call between a calling entity and a called entity. Based on at least one parameter in the call setup signaling message, it is determined whether an early media connection is required for the call.

摘要： Methods and systems for intelligent signaling-router-based surveillance are disclosed. A surveillance and signaling router receives call signaling messages, identifies call signaling messages associated with users under surveillance and determines a surveillance type for the call signaling messages. If the surveillance type is content-related, the surveillance and signaling router forwards the message to a call server. The call server replaces parameters in the message and in subsequent messages so that the call is transparently set up through a media proxy server. The media proxy server copies the media stream to a delivery function. If the surveillance type is non-content-related, the surveillance and signaling router sends a copy of the message or information extracted from the message to an external device.

摘要： A routing node for receiving, processing, and subsequently transmitting Signaling System 7 (SS7) signaling messages destined for a Media Gateway Controller (MGC) type network element is disclosed. A Circuit Identification Code (CIC) routing node is adapted to receive an ISUP message from an associated SS7 network and determine the routing destination of the message based, at least in part, on a CIC parameter value contained within the message. The ISUP message is subsequently encapsulated in an Internet Protocol (IP) envelope and transmitted to a destination node via an IP communication link. Such a CIC routing node also provides network service providers with a method of generally eliminating the need for the assignment of unique SS7 network point codes to each MGC node in a network. That is, a CIC routing node allows multiple MGC nodes to effectively correspond to a single SS7 network point code.
