Abstract
System and method for seamless switching between operator networks is disclosed. The present invention relates to communication networks and, more particularly, to switching between operators in communication networks. A network element termed as the service aggregator is provided that resides in the operator's network and acts as an intermediate between the mobile user and the operator. In addition, a switching module is provided on the mobile device of the user that interacts with the service aggregator to perform switching. Base station continuously broadcasts signaling information to the mobile device. Based on such signaling information received, the mobile device decides if it wishes to switch to another operator's network. The service aggregator establishes connection with the service gateway of the new network. Further, service aggregator sends handover signal and the mobile device switches seamlessly to the new operator's network.
