A METHOD AND SYSTEM FOR PROVIDING ENHANCED PACKET DATA SERVICES TO A USER EQUIPMENT

摘要

A method and system for providing enhanced packet data services to user equipment (UE) is disclosed. The method disclosed herein provides the mechanism for bringing the UE to a LTE network from a UMTS network or 2G network for providing enhanced packet data services. Further, the method provides a mechanism for redirecting the UE to LTE network when it is determined the UE has left the LTE network to the UMTS network or 2G network for obtaining CS services. The UE is redirected or reselected to the LTE network, upon the completion of CS services. The method also provides the approaches that allow the UE to be in the LTE network during mobility of the UE across different radio access networks.
