In Low Earth Orbit (LEO) satellite network Mobility management is one of the key technologies. The aim of mobility management is to track where the subscribers are, allowing calls, SMS and other mobile phone services to be delivered to them. In this paper, the authors have proposed an idea of controlling the frequency hops and hence controlled the mobility management cost of patHO-LEO and Mobile IP network. The trend in designing future global communication systems is to provide fast and low cost service to all users any time. Modern terrestrial wireless networks such as mobile networks provide communication to a limited geographical area. In order to provide global coverage satellite networks can be very useful with terrestrial networks.
