    The Long Term Evolution provides a high data rate and can operate in different bandwidths ranging from 1.4MHz up to 20MHz. LTE sup-ports high peak data rates (100 Mb/s in the Down Link and 50 Mb/s in the Up Link), low latency (10ms round-trip delay) and Multiple Input Multiple Out-put (MIMO) which enhances the throughput and allows seamless integration with an existing systems. However, the resources on LTE network are lim-ited and it has to be allocated in such a way that the highest throughput is attained and fairness is maintained among all types of network connections. As a result of this, allocation of network resources over LTE network has been of major concern over the past few years, so many scheduling algorithms have been proposed. This paper evaluated various scheduling algorithms in Long-Term Evolution (LTE) network and proposed a new scheduling algo-rithm that improves on the limitation of existing algorithms by making use of Prioritized Deficit Round Robin. In this paper network connection types were categorized into Real-Time (RT) and Non Real-Time connection (NRT); NRT connection is further classified into Urgent NRT (UR) and Non Urgent NRT connections, so as to give fairness to all traffic types. Resource blocks were shared between traffic types using partial sharing system and the deficits (TTI) of old connections were added on to the incoming connections. Network Connection were prioritized such that RT has preemptive power over NRT and UR has preemptive power over Non-Urgent NRT
