Optimum traffic channel in GSM network by using alternative call routing (international roaming analytic)

The increased demand of wireless mobile communications in circuit switching, and the finite resource lead to resource expansion corresponding to the demand of subscribers. This research proposed the alternative routing to optimize the traffic channel in case of mobile subscriber who is roaming in the international network. From the conventional routing of GSM network traffic channel must always return to their HPLMN for interrogation, consequently to the inefficiency routing and waste of traffic channel between the foreign network and Home-PLMN, we are assuming the alternative routing to setup direct connection to the terminating exchange, wherever the subscriber is roaming - in a foreign network or in their home network. The proposed method could implement in addition from the existing GSM network, and the relative performances for each scenario are investigated.
