To provide “transparent” broadcast services for a multi-mode wireless device capable of communicating with multiple wireless communication networks, a composite set of pertinent parameters for broadcast messages used by the multiple networks is defined. The parameters of the broadcast message for each network are mapped to corresponding parameters in the composite set. The composite set of parameters is used for processing and displaying broadcast messages received from the multiple networks. A broadcast message for each network (e.g., a CBS message in GSM or a broadcast SMS message in CDMA) is received and processed in accordance with the parameters of the message and filtering configurations applicable for the network. The parameters of the broadcast message are mapped to corresponding parameters in the composite set. The broadcast message is further processed and displayed based on the parameters in the composite set.
