Mobility and Resource Management for S-PCN and Integration with Terrestrial Mobile Networks
This paper reviews the mobility and resource management techniques used in terrestrial mobile systems such as GSM and discusses their inefficiency if directly applied to Non-Geostationary Satellite PCN (S-PCN) For these, an alternative and novel mobility management technique is presented and fully evaluated for two representative LEO and MEO constellations such as the Globalstar and ICO-10 respectively. The technique is based on dynamic location area concept and is efficient in terms of required radio, power, and network resources for paging, location update and call routing to mobile users in S-PCN. The paper then presents two possible network integration architectures between GSM and S-PCN and the impacts of this new mobility management technique on the integrated network architectures are identified and solutions proposed.
