A Signal Transfer Point (STP) is a router that relays SS7 messages between signaling end-points (SEPs) and other signaling transfer points (STPs). Typical SEPs include service switching points (SSPs) and service control points (SCPs). The STP is connected to adjacent SEPs and STPs via signaling links. Based on the address fields of the SS7 messages, the STP routes the messages to the appropriate outgoing signaling link. Edge STPs can also route based upon message body content using deep packet inspection techniques, and can provide address translations and screen content to limit the transfer of messages with dubious content or sent from unreliable sources. To meet stringent reliability requirements, STPs are typically provisioned in mated pairs.
Telecommunication number portability
InactiveUS6021126AEfficient and economical number portabilityImprove comprehensive applicabilityInterconnection arrangementsSpecial service for subscribersDomain nameIntelligent Network
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.

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.

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 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.

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.

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.

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 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.
