Methods and systems for load sharing and preserving sequencing of signaling connection control part (SCCP) messages are disclosed. According to one method, SCCP messages are received at an inbound interface module and assigned a sequence number. Each SCCP message is then transmitted using a load sharing algorithm to any one of a plurality of SCCP modules for SCCP processing. After the SCCP processing, the SCCP messages are returned to the inbound interface module and ordered based on the assigned sequence numbers the messages are then transmitted in order to an outbound interface module.

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.

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.

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. The signal transfer point decodes the response and uses the stateful processing module identifier to forward the response to the correct stateful processing module.

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.

A porting control routing (PCR) node () is adapted to efficiently route signaling messages associated with a mobile subscriber that has been either ported in to or out of a service provider's wireless communication network. The PCR node () includes both range- and exception based routing rule databases (and). These databases increase flexibility in allocating mobile identification numbers among multiple mobile service nodes. Furthermore, the association of a ported status indicator and related routing information with entries in the exception based database allows the PCR node () to more efficiently manage a service provider's mobile service resources.

Methods and systems for processing messages at a first network node in a mobile communications network are disclosed. A first message relating to a communication in a mobile communications network that includes a called directory number is received. A lookup is performed in a first database based on the called directory number to determine whether a called party has been ported out of a first network and to determine a migration status of the called party. In response to determining that the called party has been ported out of the first network, a first reply message is formulated including first routing information from the first database that indicates a second network to which the called party has been ported. If the called party has not been ported out, a second reply message is formulated including second routing information from the first database that corresponds to the determined migration status.

Methods, systems, and computer program products for post global title translation load sharing include receiving a plurality of signaling messages sent route on global title. Global title translation is performed for the signaling messages to result in multiple global title destinations for at least some of the signaling messages. One of the destination addresses is selected using the parameter in the signaling messages and the load sharing algorithm so that messages that are part of the same transaction are sent to the same destination address and messages related to different transactions are load shared among different destination addresses. Sequencing may also be performed so that sequenced messages are transmitted in the same order that they are received.

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.

Methods and systems for load sharing signaling messages among signaling links in a network utilizing an international signaling protocol are disclosed. A routing node receives a signaling message formatted according to an international signaling protocol. The routing node generates a signaling link selection parameter for the signaling message. The routing node selects an outbound signaling link based on the generated signaling link selection parameter. The number of bits in the generated SLS value is user-configurable, thus allowing load sharing among arbitrary numbers of signaling links.

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.

A flexible routing node for re-directing signaling messages in a communications network is disclosed. Re-direction or re-routing of signaling message packets is accomplished through the use of a range or block-based database in conjunction with an exception-based database. The range-based routing instruction databases incorporates a data structure that maps ranges or blocks of mobile identification numbers (MINs) to a single destination network address, while the exceptions database stores any exceptions to these range or block-based rules. The pair of routing databases is implemented such that, when a signaling message is received that requires re-direction, the exception-based database is queried first. If a match is found in the exceptions database, the signaling message is modified using the returned routing instructions and transmitted into an associated communication network. If no match is found in the exception-based database, a default query is performed against the range-based database. The signaling message is then modified using the routing instructions returned by the range-based database and transmitted into an associated communication network.
