Abstract: A method for multiple transaction capabilities application part (TCAP) operation code (opcode) screening includes receiving a first SS7 signaling message including multiple TCAP opcodes. The method further includes determining that the first SS7 signaling message requires further processing. The method further includes, in response to determining that the first SS7 signaling message requires further processing, decoding, from the first SS7 signaling message, N TCAP opcodes, where N is an integer of at least two. The method further includes, for each of the N TCAP opcodes, applying a filter and determining that one of the filters indicates that the opcode, alone or in combination with other parameters in the first SS7 signaling message, is not allowed. The method further includes, in response to determining that the one filter indicates that the opcode, alone or in combination with the other parameters is not allowed, performing an SS7 firewall action.

Abstract: Methods, systems, and computer program products for managing and selectively distributing routing information in a routing node are disclosed. In one implementation, a method for selectively distributing routing information in a routing node includes organizing internal signaling resources are organized so as to facilitate the efficient mapping of signaling system 7 (SS7) message transfer part (MTP) signaling protocol attributes to Internet protocol (IP)-based signaling resources. A routing status information sharing hierarchy is defined, which enables routing status information to be efficiently shared among members of a signaling mateset group. Members of a signaling mateset replicate and distribute SS7 MTP network management information across non-MTP signaling connections, such as IP connections.

Abstract: Methods, systems, and computer readable media for providing a multi-network equipment identity register are disclosed. According to one aspect, the subject matter described herein includes a system for providing a multi-network equipment identity register. A node in a telecommunications network receives from a requesting entity a request to check an identity of a user equipment, the request containing the identity of the user equipment, queries an EIR using the identity of the user equipment, receives a response from the EIR, and forwards the response to the requesting entity. The node includes first and second interfaces for receiving requests to check an identity of a user equipment in a first and second protocol, respectively, such that a user equipment that is blacklisted in a network that uses the first protocol is also blacklisted in a network that uses the second protocol.

Abstract: The present application describes a system and method for testing semiconductor devices and specifically for testing mixed signal semiconductor devices. The test systems are configured to test the semiconductor devices using overlapping test setups by configuring various test system elements. The various test system elements are programmed and prepared for subsequent tests concurrently with tests executing on the semiconductor devices. The test results are computed by various software computation modules configured to independently execute in parallel with the subsequent tests. The resultant test data of an executed test is shared among the various concurrently executing software computation modules using shared information storage. A tester user interface, executing on test system, provides an interface between user test scripts and software computation modules.

Abstract: Methods and systems for performing stateful signaling transactions in a distributed processing environment are disclosed. A method for performing stateful signaling transactions in a distributed processing environment includes receiving a signaling message at a routing node, such as a signal transfer point. The signaling message is distributed to one of the plurality of stateful processing modules. The receiving stateful processing module buffers the signaling message and initiates a stateful transaction based on the signaling message. Initiating the stateful transaction may include generating a query message and inserting a stateful processing module identifier in the query message. The query message is sent to an external node, such as an SCP, which formulates a response. The SCP may insert the stateful processing module in the response and send the response back to the signal transfer point.
