1. A method for processing an Internet protocol (IP) encapsulated signaling system seven (SS7) user part message utilizing a signal transfer point (STP), the method comprising:
- at a first STP;
(a) receiving an IP-encapsulated SS7 user part message transmitted from a first SS7 signaling point over a bi-directional IP signaling link, wherein the user part message excludes at least some message transfer part (MTP) level 1 and MTP level 2 information;
(b) removing an IP header from the message;
(c) adding at least some MTP level 1 and MTP level 2 information to the message;
(d) reading at least MTP level 3 information from the message; and
(e) routing the message from the bi-directional IP signaling link to a bi-directional SS7 signaling link based on at least the MTP level 3 information.

Abstract
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.
