Abstract:
A method for completing a handover of a communication signal associated with a mobile communication unit from a first wireless communication system to a second wireless communication system, the first wireless communication system comprising a landline switching element, a computing platform and a first base station element, and the second wireless communication system comprising a mobile switching element and a second base station element, the method comprising:establishing a plurality of trunks between the landline switching element and the mobile switching element, the plurality of trunks, when selected, capable of carrying user data traffic; configuring a landline number routing table in the landline switching element, the landline number routing table automatically selecting the plurality of trunks upon receipt of a guide directory number (GDN); configuring a landline trunk group table in the landline switching element, the landline trunk group table having as input an identity of the plurality of trunks and providing as output an identity of one of the plurality of trunks and an associated signaling path to the computing platform; and establishing a message translation table in the computing platform, the message translation table capable of translating a ISUP signaling message from the landline switching element into an IS-41 signaling message suitable for receipt by the mobile switching element.
