Abstract
A method and system for the routing and transmission of data to a mobile station. Upon receiving a request to deliver data addressed to the mobile station, a node in a circuit-switched network of a mobile telecommunications system identifies whether the mobile station is capable of receiving data via a packet data bearer. If so, the node further determines whether the data addressed to the mobile station should be sent via a packet data bearer in a packet-switched network instead of sending the data via a circuit-switched bearer. If it is determined that the data should be sent via a packet data bearer, then the data is transmitted to the mobile station using a selected packet data bearer. Alternatively, if the request to deliver data addressed to the mobile station is received by a node in the packet-switched network, that node determines whether the data should be sent via a circuit-switched bearer in the circuit-switched network. If so, then the data is rerouted and transmitted to the mobile station using a circuit-switched bearer.
