How to maintain an end-to-end QoS is a critical issue when the user is in the heterogeneous network environment. It needs time to rebuild or re-negotiate the user QoS profile when the mobile user hands over in the wireless networks. Because network resources may change by time, it’s hard to maintain users’ QoS demands. As user being through IMS using IMS Services and need to handover service network. After authentication and authorization success, user connect with new access network but still unable to continue using the service on IMS. It needs to delay the authentication and authorization of IMS and keeps resource reservation with QoS. They can just continue the previous service. Therefore they has waited for long time. It’so influential that IMS is mostly all prompt services. So we propose an adaptive end-to-end QoS procedure where the address getting PDF & P-CSCF first with MIIS Server of MIH. Advance finishes inserting IMS authorization and QoS procedure of IMS, which can deal with accessing the authentication and authorization network at the same time, reducing the handover waiting time. The results of our simulation show that the proposed mechanism is better both in handover times and dropping rate than old handover procedure.
