Inter-network signalling load analysis for GSM-satellite integration

The issue of selecting optimised integration level in a GSM and satellite integrated system is discussed. Criterion of performance evaluation is based on the estimation of inter-network signalling load, For signalling link dimensioning purpose, SS#7 signalling message length is estimated. The main factors to have impact on the signalling link dimensioning are identified. In particular, BSS level and MSC level integration are compared based on the proposed traffic model and analytical model. Services considered in the integrated system are call handling, location update and inter-network handover.
