Abstract: The subject matter disclosed herein includes methods, systems, and computer program products for selecting among different global title translation modes based on a message originator and performing global title translation based on the selected mode. According to one method, a global title translation mode is selected based on a message originator. A global title translation lookup is performed in accordance with the selected mode. If the global title translation according to the selected mode fails, a lookup may be performed according to at least one additional mode in a global title translation mode hierarchy.

Abstract: Methods and systems for migrating between application layer mobile signaling protocols are disclosed. For subscribers of multiple protocols, the registration status is tracked in one or more of the protocols. When a location query message for a subscriber of multiple protocols is received, it is determined whether the subscriber is registered according to the tracked protocol. If the subscriber is registered according to the tracked protocol and the request originated from an MSC of the tracked protocol, the message is routed to an HLR of the tracked protocol. If the subscriber is not registered according to the tracked protocol, a response is formulated to the first message. The response optionally includes a prefix that directs the originating MSC to route the call to an MSC of the non-tracked protocol.

Abstract: Methods, systems, and computer program products for rerouting signaling message traffic in response to unavailability of one or more services are disclosed. According to one method, service signaling message traffic is received at a signaling message routing node that provides a plurality of different services. It is determined whether at least one of the services is unavailable. In response to determining that at least one of the services is unavailable, the signaling message traffic for the unavailable service is rerouted to an alternate destination. Signaling message traffic for the remaining services is received and processed.

Abstract: Methods, systems, and computer program products for providing fault-tolerant service interaction and mediation function in a communications network are disclosed. According to one aspect, the subject matter described herein includes a method for providing fault-tolerant service interaction and mediation capability. The method includes providing an active instance of a service capability interaction manager (SCIM) function for providing service interaction and mediation between entities that request network services and entities that provide network services in a communications network. The method also includes providing a standby instance of the SCIM function. The active instance of the SCIM function performs service interaction and mediation between the entities that request network services and the entities that provide network services.

Abstract: A short message gateway may include signal transfer point (STP) functionality, mobile originating short message service center (SMSC) functionality, and short message delivery peer-to-peer (SMPP) gateway functionality. The short message gateway may receive an SS7 message including a short message payload. The short message gateway may formulate an SMPP message including the short message payload and access one or more internal address resolution and/or number portability databases to determine the destination address for the SMPP message. The short message gateway may then forward the SMPP message to its destination.

Abstract: Methods and systems for universal, automatic service selection are disclosed. A method for universal, automatic service selection includes receiving signaling messages and identifying signaling connection control part (SCCP) messages from the signaling messages. The SCCP messages are decoded to extract SCCP parameters and application layer parameters from the messages. A routing address translation service is selected for each of the SCCP messages based on application identifiers that identify application layer message types alone or in combination with other parameters. Selecting the routing address translation service in this manner makes the service selection more robust and universally applicable, especially in networks where different or non-standard selector parameters are utilized.

Abstract: Methods, systems, and computer program products for flexible global title translation load sharing are disclosed. GTT load sharing groups are defined. Each GTT load sharing group may include one or more point codes. At least one of the point codes may appear in more than one of the GTT load sharing groups. When signaling messages requiring GTT are received, the signaling messages are load shared using the GTT load sharing groups.
