A Common Channel Signaling Network such as the SS7 network is configured as a virtual signaling network, such that the network is shared in common among several users. Each user, which may be a private network operator, an ICO, a RBOC, a cellular mobile carrier, or an interexchange carrier, appears to control the signaling network and is enabled to use a wide variety of its capabilities to transmit and receive both trunk signaling messages and database messages to and from other networks connected to the virtual signaling network. The invention is implemented by interconnecting signal transfer points (STPs) within the virtual signaling network that operate in accordance with our invention with the SS7 switches and/or signal transfer points of other networks. Signaling messages presented to the STPs in the virtual signaling network are screened to insure security, translated in accordance with stored translation tables so as to allow message transport between the user's network and the appropriate destination network, and then addressed and routed to the proper destinations.
In a shared signaling network, a method of processing signaling messages generated in one of a plurality of interconnected telecommunications networks, each of said signaling messages containing information used to control the routing of corresponding telecommunications traffic originating and/or terminating in said one of a plurality of interconnected telecommunications networks, said method comprising the steps of
A method of processing signaling messages originated in a first telecommunications network in a signaling network associated with a second telecommunications network, each of said signaling messages containing information used for routing associated telecommunications traffic, said processing method including the steps of:
A method of transmitting signaling messages between interconnected signal transfer points (STPs), said signaling messages including information for controlling the flow of telecommunications messages between associated interconnected telecommunications networks, said method comprising the steps of:
A method for transmitting signaling messages including routing messages and/or data base queries between a plurality of interconnected signal transfer points (STPs) in a shared CCS7 signaling system, said method including the steps of
A method for transmitting signaling messages and data base queries between a plurality of interconnected telecommunications networks, said networks each arranged to originate and/or terminate calls that begin in or are destined for others of said telecommunications networks, said signaling messages including encoded information describing the origin and destination of said calls and the type of encoding used to encode said signaling messages, said method comprising
A method for processing signaling messages in a signal transfer point (STP), said signaling messages controlling the transport of calls in an associated telecommunications network, said method including:
