METHOD FOR PROVIDING CALL PROCEDURE IN MOBILE COMMUNICATION SERVICE SYSTEM INTELLIGENT NETWORK SYSTEM AND ONLINE CHARGING SYSTEM FOR CALL PROCEDURE

摘要

The LTE (Long Term Evolution) network has a technical difference from a synchronous network (CDMA network) or an asynchronous network (WCDMA network) and is different in the network configuration. In addition, real-time billing and limit management are managed by a more advanced online charging system (OCS) than intelligent network systems. In other words, in the LTE network, since the role of the existing intelligent network system is played by the OCS, convergence of the existing network is not easy, so subscribers using the existing limit plan service already available can receive the same limit plan in the LTE network. There is no problem. Likewise, there are technical limitations when a subscriber applying the LTE limit plan wants to apply the same limit plan service in the existing network. Accordingly, in the embodiment of the present invention, regardless of the call connection of the LTE network or the CDMA/WCDMA network, the call processing service of the subscriber of the limit rate plan is processed in the same manner, thereby maintaining service continuity and improving user satisfaction. It is intended to propose a call processing technique in a communication service system.
