The high quality of high-speed communication services is now a requirement for LTE (Long Term Evolution) users, resulting in high traffic capacity requirements. Jombang Rawa area is one area that has a high traffic capacity. To overcome this problem, X operator rolled out a mobile network project called roll out project that aims to provide sufficient LTE network capacity for operator X customers. In the project, the capacity of the transport network is done using a microwave backhaul which aims to support the new LTE site so that there is no bandwidth shortage in the new site path. The method used to obtain the appropriate traffic for the new site path is the overbooking calculation method. Based on Overbooking calculations of 102 sites, there are 22 sites that require a propose bandwidth capacity solution. Using the overbooking method there is a configuration upgrade as a solution to deal with trafficked paths.

This paper discusses the mobility management for high-speed users, which is a crucial challenge for all mobile operators, especially when users are moving vertically across different network technologies. Mobility, also known as seamless connectivity, is directly influencing the quality of service (QoS). Mobility management-Handover (HO) performance was evaluated by field measurements of a Long Term Evolution (LTE) network of a mobile operator in the Middle East. Drive test measurements were used to analyze the results of different high-speed scenarios. User Equipment (UE) with high speed of 80-140km/h causes a high risk of failure of seamless connectivity as the HO procedure timing is longer than for UE with smaller speed. HO failure and call drop may occur when UE is moving with high speed across two adjacent cells in highways. During measurements, HO failure occurred when UE speed was 140km/h, and HO preparation timing increased when UE speed increased.

In the last years, the video content consumed by mobile users has increased exponentially. Since mobile network capacity cannot be increased as fast as required, it is crucial to develop intelligent schedulers that allocate radio resources very efficiently and are able to provide a high Quality of Experience (QoE) to most of the users. This paper proposes a new and effective scheduling solution—the Maximum Buffer Filling (MBF) algorithm—which aims to increase the number of satisfied users in video streaming services provided by wireless networks. The MBF algorithm uses the current buffer level at the client side and the radio channel conditions, which are reported to the network by the client, as well as the bitrate of the requested video segment. The proposed scheduling strategy can also fulfill different satisfaction criteria, since it can be tuned to maximize the numbers of users with high QoE levels or to minimize the number of users with low QoE levels. A simulation framework was developed, considering a Long Term Evolution (LTE) scenario, in order to assess the performance of the proposed scheduling scheme and to compare it with other well-known scheduling solutions. The results show the superior performance achieved by the proposed technique, in terms of the number of satisfied and unsatisfied users.

The LTE Long Term Evolution highly developed Technology, Handover is the essential function of the mobility of user in cellular networks in Time Division Duplex as well as Frequency Division Duplex. Handover is one of the essential that can affect the [QoS] Quality of Service with Capacity of Mobile Broadband Networks. Within mobile cellular network communication systems, a (spectrum) limited shared resource needs to be shared with all the users, so full duplex communication is achieved. This paper involves studying diverse Hand over delay parameters and also focus on reducing “Hard Handover delay” by minimizing interruption time, activation time, wireless channel accesses time as well as the wireless link transmission delay. Technique is developed in order to reduce the handover delay time in Time Division Duplex network which too reduces the wireless channel access time and the wireless link transmission delay. A novel handover algorithm is developed which would decreases the handover delay time and access time inside mobile network environment.Additional work may be conceded on to obtain enhanced performance and Quality of service in Time Division Duplex mobile network.

Quality of service (QoS) and network capacity are being insisted as the two dominant factors for the utmost network satisfaction within any mobile network contracts. On the other hand, the heterogeneous network (HetNets), which are constructed based on sub-network layers' cooperation between macrocell and shorter-range applications like micro, femto and relay nodes, are also introduced as an open door to the recent researches towards the desired network satisfaction for the recently upgraded networks like LTE-Advanced (LTE-A). Nevertheless, since any network cooperation is expected to include a number of challenges; this cooperation is not excluded of dealing with degrading effects, such as interference, among the sub-network elements. This chapter presents a detailed discussion in self-organizing network (SON) methodology, as a novel solution to deal with network challenges, e.g. inter-cell interference coordination (ICIC), mobility, power control, etc. to improve the network quality and capacity.

This work focuses on providing enhanced capacity planning and resource management for 5G networks through bridging data science concepts with usual network planning processes. For this purpose, we propose using a subscriber-centric clustering approach, based on subscribers’ behavior, leading to the concept of intelligent 5G networks, ultimately resulting in relevant advantages and improvements to the cellular planning process. Such advanced data-science-related techniques provide powerful insights into subscribers’ characteristics that can be extremely useful for mobile network operators. We demonstrate the advantages of using such techniques, focusing on the particular case of subscribers’ behavior, which has not yet been the subject of relevant studies. In this sense, we extend previously developed work, contributing further by showing that by applying advanced clustering, two new behavioral clusters appear, whose traffic generation and capacity demand profiles are very relevant for network planning and resource management and, therefore, should be taken into account by mobile network operators. As far as we are aware, for network, capacity, and resource management planning processes, it is the first time that such groups have been considered. We also contribute by demonstrating that there are extensive advantages for both operators and subscribers by performing advanced subscriber clustering and analytics.

The work proposes and investigates an intelligent method and algorithms for on-line assessment of the state of network elements to ensure the required quality indicators of provided communication services in corporate high-speed multiservice communication networks. The developed method and algorithms operate in a mode close to real time. One of the features of corporate multiservice communication networks is the high dynamics of changes in their state. The main task of the automated control system, which is an integral part of the corporate multiservice communication network, is to ensure the specified quality of the provided communication services to the consumer. Thus, the relevance of the research presented in the work is due to the fact that most of the management processes in corporate high-speed multiservice communication networks must be implemented in a mode close to real time with a given quality. The basis of the method for operational assessment of the state of network elements is the concept of creating and using intelligent agents. In the proposed approach, intelligent agents are created as hierarchical fuzzy situational networks, in which control solutions, in contrast to known methods based on the use of reference situations, are applied based on solving a hierarchical set of optimization problems using fuzzy mathematical programming methods. The main paradigm of their functioning is “situation -action”.

3Rd Generation Partnership Project

The mobile service was globally popularized with the ease of internet access enabled with the 3rd generation of networks and the broadband wireless speeds enabled with the 4th generation known as the long-term evolution (LTE). LTE became the most popular architecture with around 600 commercially launched networks worldwide. This prompted further advancements for hundreds of gigabits per second speeds and connect tens of billions of devices worldwide. The LTE-advanced and LTE-advanced-pro were introduced as intermediary network enhancements towards the future 5th network generation. For the first time, the 3rd generation partnership project (3GPP) architectures included built-in features for conducting mobile network forensics so investigators can structure and coordinate the investigation with maximum safeguards for the quality of the evidence, users' privacy, and network performance. To fully capitalize on the forensics features, this chapter details all the infrastructural, security, and forensics-related aspects of the modern 3GPP networks.

Coverage Planning

Long-Term Evolution (LTE) planning is considered as one of the most important processes in the process of establishment mobile network. The planning process includes coverage planning and capacity planning. There are many parameters, which affect the network coverage planning, such as neighbor cell load, frequency range, bandwidth, e.t.c. By tuning these parameters, the network will provide the best performance from the view of coverage and capacity requirements. In this paper, the effect of changing different parameters on the maximum allowable path loss (MAPL) and cell range is presented. The results show that the cell limit increases when the network operates on 700 MHz range and on 20 MHz BW. Furthermore, it is shown that the load of neighbor eNB has a large effect on MAPL. Finally, it shows that there is a large difference between the cell limit in different clutter type.
