#QOS PACKET SCHEDULER SERVICE FREE#

The goal of efficient scheduling approach is critical in meeting LTE targets because choosing a suitable scheduling mechanism is not well defined in the 3GPP specifications for LTE, but vendors are free to adopt, configure and implement their own algorithms depending on the problems of the system. To effectively support the present types of services, effective use of scarce shared spectrum resources is necessary. Each bearer has a corresponding QoS class identifier (QCI), and each QoS is categorised with the service type, priority, packet error rate (PER) and packet delay budget (PDB). A bearer is established amongst UE and packet data network gateway to show the use of data flow in the evolved packet system. QoS requirements should be met for each bearer. These schedulers are responsible for selecting good frequency and time resolutions, which are used in the allocation of resource blocks (RB) between different user equipment (UE) with consideration for channel conditions and QoS requirements thus, packet schedulers play an important role. Radio resource allocations have been extensively studied in OFDMA systems using packet schedulers. Radio resource allocation is needed to provide QoS requirements to many users. Allocation of resources to numerous users with different QoS requirements is challenging. Дespite the benefits of LTE, the resource allocation issue remains a significant problem. Furthermore, in only a decade, the amount of data handled by LTE networks has increased by a factor of 100 from under 3 exabytes in 2010, it is expected to exceed 190 and 500 exabytes by 20, respectively. To achieve high peak data rate, LTE adopts orthogonal frequency division multiple access (OFDMA) as the downlink access technology and exploits single-carrier frequency division multiple access for uplink transmission. LTE aims to support peak data rate, high spectral efficiency, high coverage area and improved latency. The Third Generation Partnership Project (3GPP) introduced Long Term Evolution (LTE) as an answer to the above challenges. These services, which normally have different delay constraints, bandwidth requirements and quality of service (QoS) requirements, cause network problems. With the emergence of advanced communication devices, networks now support such services as video streaming, web browsing and online gaming. Early mobile communication systems offered video services, data and voice. In the past decades, considerable development has been observed in communication networks. Simulation is used to evaluate the performance of the proposed algorithm, and results demonstrate that it performs better than do all other algorithms according to the measured metrics. The new algorithm is formulated as an optimisation problem where network resources are allocated according to usersвЂ™ priority, whereas the scheduling algorithm decides on the basis of usersвЂ™ channel status to satisfy the demands of QoS. In this work, a novel downlink resource allocation algorithm that uses quality of service (QoS) requirements and channel conditions to address performance degradation is proposed. Furthermore, the existing radio resource algorithm suffers from performance degradation under prioritised conditions because of the minimum data rate used to determine the transmission order. However, the scheduling algorithm problem of distributing radio resources to users is not well defined in the LTE standard and thus considerably affects transmission order. LTE networks implement resource allocation algorithms to distribute radio resource to satisfy the bandwidth and delay requirements of users. The increasing demand for network applications, such as teleconferencing, multimedia messaging and mobile TV, which have diverse requirements, has resulted in the introduction of Long Term Evolution (LTE) by the Third Generation Partnership Project (3GPP).
