摘要：There are several new multimedia applications are available now, so it becomes more important that wireless networks satisfy QoS requirements. While in the handover, blocking a new connection is more preferable than dropping the connection after it has already begun. One way to improve the cellular network performance is to use efficient handover prioritization schemes when user is switching between the cells. Some advance schemes are discussed that have common characteristic reducing the call dropping probability at the expense of increased call blocking probability. In the multilevel bandwidth allocation scheme, when an available bandwidth is low, the scheme releases some bandwidth from the already admitted non real time calls for handling new and handover calls. But the problem is that all the users are treated in the same way. So as a proposed work we extend the multilevel bandwidth allocation scheme with user priority. So mechanism proposes an order in which the bandwidth is taken from the user for giving to handover calls.
