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. The secure channel may enable the mobile terminal to communicate with the service provider network using messages not meeting the criterion.

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.

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.

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.

For use in a telecommunication node, a scalable call-processing system is provided to process signaling messages in a distributed processing environment. The call-processing system includes: (i) processing nodes operable to process signaling messages, each of the processing nodes configured to monitor a respective loading factor and produce respective real-time loading information; (ii) resource server nodes operable to provide resources to the processing nodes, each of the resource server nodes configured to monitor a respective loading factor and produce respective real-time loading information; and a load-sharing manager connected to receive the real-time loading information from each of the processing nodes and each of the resource server nodes, the load-sharing manager further connected to receive the signaling messages and distribute the signaling messages to the processing nodes for processing using the resource server nodes based on load-sharing rules generated using programmable policies and the real-time loading information.

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.
