A telecommunications system wherein the dialing of a directory number which has been ported triggers an intelligent network signal which is directed to the Internet. The signal is transmitted through the Internet to a database in the Internet. The database returns call set up directions which are used by the originating switching system to establish a voice link from the calling station to the station having the ported number. The intelligent network signal may be transmitted from the originating switching system to a signal transfer point (STP) and to the Internet. Within the Internet the signal is directed to an Internet database where a real number for the ported number is obtained. This is transmitted back to the signal switching point, which then uses the real number to complete the connection. In another embodiment, where a number has been ported to a station that is connected only to the Internet, the Internet database may provide a domain name address. This address is then used to establish a link through the Internet between the calling and called station. In this instance the Internet handles both the signaling and the voice connections.

A method of negotiating a call capability between signalling points in a telecommunications system. The method comprises sending a capability preference or prioritised list of preferences from an originating signalling point to a terminating signalling point or signalling transfer point, at the Call Control level. A capability acceptance is returned from the terminating signalling point or signalling transfer point to the originating signalling point at the Call Control level, if the terminating signalling point or signalling transfer point accepts a preference sent by the originating signalling point.

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.

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 system and method for application location register routing at a signal transfer point (26) are provided. The signal transfer point (26) includes processor clusters (64, 66, 68) and databases (236, 238) for processing queries including global title translation, local number portability, and application location register routing. A query message is received by the signal transfer point (26), a first database residing in the signal transfer point (26) is accessed to determine the location of a second database (238) also residing in the signal transfer point for processing the query message. The second database (238) is then accessed to obtain the network address of a home location register or short message service center, which is then used to deliver the query message to the network node specified by the network address.

Disclosed is a mobility management routing (MMR) node that performs location management signaling operations associated with mobile subscribers. The MMR node may also perform the signaling message routing functionality typically provided by a network routing node, such as a signaling system 7 (SS7) signal transfer point (STP) or an SS7-over-Internet protocol signaling gateway (SG). The MMR node caches mobile subscriber information extracted from messages transmitted between an HLR and a VLR and responds to some of the messages using the cached information. As a result, signaling message traffic and call setup time in a mobile communications network are reduced.

A system for routing Signaling System 7 (SS7) signaling traffic over an Internet Protocol (IP) network includes two or more signaling points, each signaling point capable of sending and receiving SS7 signaling traffic over an SS7 network and a first Signaling Gateway (SG) adapted for receiving SS7 signaling traffic from a first signaling point over the SS7 network. The first SG is configured to convert SS7 signaling traffic into an IP message stream and to route the IP message stream on the IP network to a second SG. The second SG is configured to receive the IP message stream via peer-to-peer IP communications over said IP network with said first SG and to recover the SS7 signaling traffic from the IP message stream. Peer-to-peer communications between the first and second SG is supported by conversion layers within the SG, in the form of an SCTP and M3UA protocols that allows peer IP signaling between the two SGs.

A method and system for forwarding information, such as a message waiting indicator (MWI) message, to a telephone number corresponding to a foreign network (e.g., a wireless network) and a shared NPA/NXX. The invention evaluates individual telephone numbers of shared NPA/NXXs to determine to what networks to send messages. A representative embodiment of the invention uses a service control point and service package application to deliver an MWI message from a messaging service provider to a wireless (i.e., foreign network) telephone number of a shared NPA/NXX. Shared NPA/NXXs are marked as “portable” in a signal transfer point for forwarding to the service control point, which determines whether the shared NPA/NXX telephone numbers require local number portability global title translation or should be forwarded to an inter-switch voicemail routing (ISVMR) service package application. The ISVMR service package application determines the point code to which the MWI message should be routed.

Methods and systems for associating a plurality of different routes with the same destination and for routing signaling messages to the destination based on originating information associated with non-adjacent signaling nodes are disclosed. A routing database in a signal transfer point includes multiple routes to the same destination. The routes are distinguishable from each other in the routing database using message origination information associated with signaling nodes that are not adjacent to the signal transfer point. When a signaling message is received, origination and destination information in the signaling message are used in combination to select among multiple routes to a destination having a network address corresponding to the destination information in the signaling message. The signaling message is then routed over the route selected using the originating information. The selected route may be a high-speed route used to provide a particular quality of service.

The system is featured as the follows. At least one short message gateway is connected to two or above two signaling transfer points of mobile network as well as to two or above two short message centres. It can be made a spare gateway for some other short message centre gateway since the short message centre gateway is connected with above one signaling transfer points so that chaining to be switched to preset backup short message centre can be ensured by utilizing global code address varying function when certain short message centre signaling gateway if fault. The same as above, short message can be retransmitted to spare short message centre for processing when certain short message centre is fault since short message gate way is also connected with spare short message centre in addition to its mainly used short message centre.

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.

A method of providing SMS delivery to recipients migrated across different technology networks. The method includes receiving a short message service (SMS) text message from a sender at a short message service center (SMSC), wherein the SMS text message includes a destination number for a recipient of the SMS text message. A first routing request is sent to a database in a first network for SMS routing information for the destination number via a first signal transfer point (STP). The first STP determines whether the destination number is a migrated or a non-migrated destination number based on data received from the first database. An an error indication is provided to the SMSC if the destination number and the first routing request are for different communication networks. Finally, a second routing request is sent to a second database in a second network for SMS routing information for the destination number via a second STP.

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.
