Abstract
A system and method for reducing or eliminating the transference of mobile terminal mobility management information caused by temporary signal interferences blocking communications is disclosed. When the distance of a mobile terminal from a base station servicing a first network system exceeds a threshold value, the mobile terminal's distances from other base stations (servicing other network systems) are determined and the shortest distance, corresponding to a second network system, is selected and control transferred. The mobility management information for the mobile terminal, however, resident within the first network system, remains within the first network system after the control transference, the information being accessible by the second network system via a packet switch interconnecting the first and second network systems.
