| Abstract: | This poper discusses a design for using Low-Earth-Orbit(LEO)mobile satellite system to support the blocked handoffs of the ground celluar networks when they are overlaided.Normally, the users will try to communicate by the ground and take the LEO satellite system as back-up system or a emergency communication system. The correspondent mathematic model is deduced. And the numerical computation using eodneering data for the model is carried out.The resultS show that this design can effictently improve the traffic block of the ground networks. |
