Mobile Communication Case Study

I. INTRODUCTION
Mobile communications has played a very important role in the economic and social development of most countries as shown in studies by the Broadband Commission. Increasing number of mobile users has given rise to the need of high speed, reliable and seamless network connectivity. With this high pace of innovations in smart mobile devices and applications, there is an ever increasing demand for better coverage and higher data rates. It is worth noting that most data traffic is generated indoors as in homes, offices or in other public hot spots like shopping malls, airports, stations etc.

However, mobile signals in these environments suffer from multipath fading, penetration and scattering effects and other losses. Many solutions

Many of these services like Web surfing, downloading emails, video streaming and video calls require high speed connections and generate large amounts of data traffic to the network. The customer expectations are rising and soon the mobile terminals will have to achieve the same bitrates as the current fixed internet connections. However, many surveys show that many mobile and internet users at home and certain medium enterprises experience a poor indoor coverage problem primarily caused by wall attenuations, multipath losses, scattering etc. It has been identified that poor coverage is the main reason for churn, which is very costly for operators in saturated markets. Providing good indoor coverage in a cost effective manner is thus a demanding challenge for operators. Coverage has always been an important issue in mobile telecom networks. It has traditionally been a problem in rural areas due to the long distance between base stations apart from the indoor environment as discussed above. The vendors have to constantly come up with solutions to make the best of the limited radio resources that are available at their disposal to improve the

Workorder is XML (eXtensible Markup Language) file, which contains the femto cluster Id, software version, geographical location, serial number etc of the femto. After workorder is created by WPS, it should be uploaded into Wireless Management System (WMS). Now, an entity called femto is created in the WMS. Once this is done, it means that femto is pre-provisioned. Then a femto cluster is created on WMS. That is an icon is created representing a mimic of femto.

B. Send Registration events from Small Cell to HDM
To simulate the functionality of femto, Customer Premise Equipment (CPE) simulator is used. CPE simulators consists of group of files, templates, scripts related to femto. The CPE simulator and HDM should be connected to send the registration requests. The simulator should know for which HDM the request has to be sent. So, IP address of HDM should be mentioned. Femto has an unique serial number. By running the scripts using the serial number of femto, from the simulator a request is sent to HDM. The communication between simulator and HDM is through TR-069 protocol.
