A short message gateway may include signal transfer point (STP) functionality, mobile originating short message service center (SMSC) functionality, and short message delivery point-to-point (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 method of routing signalling information at a signalling transfer point of a telecommunication network. A Global Title Routing Case (GTRC) table is provided for mapping Global Titles to GTRCs, where each GTRC is allocated a primary and secondary destination signalling point. At least one peak time period is predefined, and said primary and secondary destination signalling points are swapped for a fraction of said GTRCs during said peak period to allow for load sharing during this period. For a signalling transfer request received at the signalling transfer point, the Global Title associated with the request is mapped to a GTRC using the GTRC table, and the destination signalling point is determined in dependence upon the primary and secondary destination signalling points allocated to the mapped GTRC and signalling point availability, and, in the case of said fraction of GTRCs, the time at which the request is received.

Migration of a circuit-based-switch to a packet-based-soft-switch in a SS7 telecommunications network is accomplished with no disruption to subscriber service and retains and reuses the assigned signaling point code (SPC) of the existing circuit-based-switch. The system and method inserts a new soft-switch between an SS7 signaling transfer point (STP) and the existing circuit-based-switch in a way where traffic is split incrementally off the circuit-based-switch to the soft-switch so that no administrative changes are required at either the STP or the existing circuit-based-switch. The soft-switch is gradually cutover to act as a proxy STP and tandem switch for the existing circuit-based-switch and routes all calls to and from the network on behalf of the existing switch. The system makes use of multiple internal networks of the soft-switch to accomplish the controlled routing of bi-directional traffic. The circuit-based-switch can eventually be removed from service after subscribers are migrated to the new soft-switch.

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.

Methods and systems for transmitting user part messages between signaling system seven (SS7) signaling points over an internet protocol (IP) network include receiving, at a signal transfer point, a first SS7 user part message. The first SS7 user part message can be received from a first SS7 signaling point, such as a service switching point (SSP). The first SS7 signaling point is encapsulated in a first IP packet. The first IP packet is transmitted to a second SS7 signaling point over an IP network.

Methods and systems for automatically bypassing a short message service center for short message service (SMS) messages destined for predetermined SMPP destinations are disclosed. A signal transfer point may receive SMS messages that are global title addressed to a short message service center. The signal transfer point may internally route such messages to a short message gateway. The short message gateway may identify SMS messages destined for predetermined SMPP destinations and forward those messages to the destinations in a manner that bypasses the SMSC. For other SMS messages, the short message gateway may forward these messages to the SMSC for delivery.
