چکیده

In this paper, new features of satellite configuration, Such as IP network  based infrastructure and separated signaling and media  are considered to propose a variety of satellite configurations in different orbits. Because of their  different altitude in space such as Low Earth Orbit(LEO) and Geostationary orbit (GEO). A test bed used to test call setup delay in a one space link to process the Media Gateway Control protocol calls was reviewed.  Furthermore, three different call flows is presented by M/M/1 queuing model that can be used for deploying and evaluating Next Generation Network for satellite configurations. These call flows help to verify Media Gateway Controller protocol and also allow testing and evaluating  in various call set up delay time for different satellite configurations . In these simulations, a satellite is a Media Gateway Controller node for receiving and transmitting IP messages in a Space link  and a ground stations is Media Gateway node.
