Recent years have witnessed a new version of Internet protocol and concepts of new protocol are heavily relied on for transition from the traditional IPv4-based Internet to an IPv6-based Internet. As a result it is expected that mobile node is General Packet Radio Service (GPRS) with IPv6 support likely to use IPv4 services. Therefore great concerns to transition strategy planners is how to provide connectivity between IPv6-enabled end user to IPv4. As a result many interworking techniques in

... rms transition mechanisms are proposed by researchers. But their applicability between GPRS and Internet influences many factors such as end-to-end integrity of data, security of communication. Therefore paper mainly focuses on the applicability of transition mechanism where these factors are main concern from GPRS user point of view.
