The handover method of a communication signal (270) associated with a mobile communication unit (209) operates between a first wireless communication system (202) and a second wireless communication system (204). The first wireless communication system includes a landline switching element (211), a computing platform (212) and a first base station system element (206). The second wireless communication system includes a mobile switching element (216) and a second base station system element (208). The method includes establishing multiple circuit links between the first base station system element and the mobile switching element, and then detecting, by the first wireless communication system, that a handover of the communication signal is desired. The method further includes forwarding, by the computer platform, a message (260) from the computer platform to the mobile switching element, and selecting, by the first wireless communication system, a selected circuit link (250) from the multiple circuit links. Based on the message, allocating, by the second wireless communication system, a mobile communication resource and finally transferring the communication signal to the mobile communication resource via the selected circuit link (250).
