Abstract: The present disclosure relates generally to systems and methods for providing secure network access in fixed mobile converged telecommunications systems. In one example, a method includes establishing, by a fixed access device, a connection with a mobile terminal over an air interface. The fixed access device may also establish a limited channel with a service provider network via a broadband interface. The limited channel is restricted to messages meeting one or more criterion. The mobile terminal may be authenticated with the service provider network via the limited channel using authentication information associated with the mobile terminal, and the service provider network has a preexisting relationship with the mobile terminal. A secure channel may be established between the fixed access device and the service provider network after the mobile terminal is authenticated.

Abstract: A test controller for use in a telecommunication system is provided for inexpensively and quickly testing a telecommunication device. The test controller receives a test call from an originating terminal and allocates a voice path within the telecommunication device for the test call to establish a call connection for the test call between the originating terminal and a destination terminal via the allocated voice path and a packet-switched network.

Abstract: A trunk gateway simulator for use in testing a telecommunications switch includes a message receiver, a message handler, and a message transmitter. Upon receipt of a message from a telecommunications switch, the trunk gateway simulator creates an instance of the message handler in a thread to generate a response message. Once generated, the response message is transmitted to the telecommunications switch. The trunk gateway simulator may operate as a stateless device, generating a response message in accordance with a received message without reference to previous received messages. The trunk gateway simulator may employ regular expressions in parsing received messages. The trunk gateway simulator may collect statistical information on one or more attributes of the received messages.

Abstract: For use in a telecommunication node, a scalable call-processing system is provided to process signaling messages in a distributed processing environment.

Abstract: A system for routing SIP (session initiation protocol) messages is provided. The system includes a first network element that is operable to send a message. The system also includes a second network element that is operable when overloaded and in response to receiving the message to send a reply message to the first network element indicating that the second network element is overloaded.

Abstract: A method for optimizing a network based on a performance knowledge base is provided. The network comprises a plurality of network elements. The method includes analyzing raw performance data for each of the network elements in real-time to generate processed data based on network policies and optimization rules stored in the performance knowledge base and optimizing the network based on the processed data.

Abstract: A switch for use in a telecommunication network is provided that includes a plurality of call control agent functions and a call control function. At least two of the call control agent functions are associated with different signaling protocols. The signaling protocols define a plurality of signaling control primitives. The call control function is operable to control routing of telephone calls through the switch. The call control function is accessed using an application programming interface (API). The API includes a plurality of classes defining objects representing the signaling control primitives.

Abstract: For use in a telecommunication network, a network node includes a sending entity associated with a first one of a plurality of subsystems, a receiving entity associated with a second one of the plurality of subsystems and a common interface handler in communication with the sending entity and the receiving entity. The common interface handler is operable to receive a message including identification information that is in a standard format capable of being utilized by each of the subsystems from the sending entity. The common interface handler is further operable to identify the receiving entity from the identification information and transmit the message to the receiving entity.

Abstract: A telecommunication node controls overload conditions in a distributed processing environment using processing nodes that include: (i) a load monitor configured to monitor a loading factor for the processing node and produce real-time loading factor information; and (ii) a call processor operable to process signaling messages. In addition, the telecommunication node uses signaling nodes that include: (i) a load information list including the real-time loading factor information received from each of the processing nodes; (ii) an overload policy list including programmable overload reaction policies for each of the processing nodes, in which the overload reaction policies control overload conditions of the processing nodes based on the real-time loading factor information; and (iii) a load distributor configured to select one of the processing nodes to process one of the signaling messages based on the real-time loading factor information and the overload reaction policies.
