Long Term Evolution (LTE) is a wireless communications standard defined by the 4th Generation Project (4G). The new standard provides low latency, high throughput packet data communication. The network uses the vital handover mechanism to facilitate efficient User Equipment (UE) movement across eNodeB (eNB) stations, forming an LTE system. Nevertheless, the handover scheme comprises disconnection when moving across cells because of traffic congestion in the LTE network; hence, in-progress calls might be interrupted for a short duration as the equipment moves from one cell to another, leading to potential packet loss and transmission latency challenges. Many researches had been investigated which aimed to control the traffic of cellular networks by assign a priority for handover calls. These priorities will be used to locate bandwidth for a call based on the bandwidth performance metric. This paper proposes new method called X2Bayes. This approach that facilitates the LTE system to prioritize calls based on levels. High-level calls (e.g., video calls), low-level calls (e.g., voice calls), and lastly, lowest-level calls (e.g., messages and emails) are prioritized, in this order when the bandwidth is insufficient based on fairness bandwidth that can provide high QoS, decrease call dropping in cellular networks. That helps to enhance the handover speed and handover latency by applying class call priorities during handover technique. This approach helps reduce denote call count corresponding to the handover process. The initial user equipment (UE) location is identified to determine the closest eNB station using GPS. Subsequently, the X2Bayes technique is employed to determine ToS for incoming calls. Next, the E-UTRAN NodeB (eNB) is identified for handover. Prior knowledge concerning the resource of the destination eNB allows for a prudent node selection decision, facilitating better network transmission quality.
