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.

A network element provides service control point or database node front end processing functionality, as well as routing functionality for routing data packets through a network. The network element includes a first communication module for receiving data packets from a first communication network. A second communication module transmits data packets over a second communications network. A database access control (DAC) process queries a DAC database and modifies received packets to include information returned by the database lookup.

Methods and systems for interconnecting SS7 signaling points include connecting an edge device to a plurality of SS7 service switching points using fixed-bandwidth SS7 links. The edge device is connected to an SS7/IP gateway using a variable-bandwidth signaling link. The edge device multiplexes SS7 messages received over the fixed-bandwidth signaling links and transmits the message over the variable-bandwidth signaling link.

A routing node for receiving, processing, and subsequently transmitting Signaling System(SS) signaling messages destined for a Media Gateway Controller (MGC) type network element is disclosed. A Circuit Identification Code (CIC) routing node is adapted to receive an ISUP message from an associated SSnetwork and determine the routing destination of the message based, at least in part, on a CIC parameter value contained within the message. The ISUP message is subsequently encapsulated in an Internet Protocol (IP) envelope and transmitted to a destination node via an IP communication link. Such a CIC routing node also provides network service providers with a method of generally eliminating the need for the assignment of unique SSnetwork point codes to each MGC node in a network. That is, a CIC routing node allows multiple MGC nodes to effectively correspond to a single SSnetwork point code.

Seamless transport of messages is provided between SS7 network elements and Internet Protocol (IP) network elements using an STP as an intermediary. Thus, messages may be routed between a first SP and a second SP via an STP using IP. Messages may be routed between an SP and an IP node via an STP using IP. Messages also may be routed between a first IP node and a second IP node via an STP using IP. Thus, the STP can be used as a vehicle for message transport among nodes of an SS7 network, among nodes of an IP network and between SS7 and IP networks. SS7 messages are bidirectionally communicated between an STP and at least one other SP of an SS7 network using IP, preferably TCP/IP. Preferably, SS7 messages are bidirectionally communicated between an STP and at least one SCP using IP. In particular, a first SS7 message that is received from the STP includes an SS7 Message Transfer Part (MTP) layer, an SS7 Signaling Connection Control Part (SCCP) layer and an SS7 Transaction Capability Application Part (TCAP) layer. The MTP layer (SS7 levels 1-3) is stripped from the first SS7 message. An IP routing layer is added to the SSCP layer and the TCAP layer that remain in the first SS7 message, to create a first IP message. The IP routing layer includes an IP address. The first IP message is transmitted to the IP address over an IP network. A second IP message is received from the IP network. The second IP message includes an SS7 SCCP layer, an SS7 TCAP layer and an IP routing layer. The IP routing layer is stripped from the second IP message to create a second SS7 message including an SS7 SCCP layer and an SS7 TCAP layer. The second SS7 message is then transferred to the STP.
