Abstract

Method and system integrating wireless/wireline and circuit/packet networks (to bypass GSM Memorandum of Understandings) for cellular/PCS services so that GSM subscribers roaming into CDMA networks can be provided with basic wireless call delivery services as long as the roamers can pay the bill with their valid credit card. This is achieved by integrating wireless and wireline networks as well as circuit and packet networks, using IP networks and protocols as an alternative to the existing telephony-based approach.
