Femtocells are low-power and low-cost base stations that provide residential cellular services, providing a coverage of roughly 10 m [1]. They can integrate with mobile operator through a broadband connection, typically ADSL. In General, femtocell makes that the traffic from the home cellular system, deviates through the broadband connection, releasing the resource consumption of the macrocell. The 3GPP has introduced the concept of Closed Subscriber Group (CSG), which essentially identifies a group of subscribers who have access permission to one or more cells. Femtocells basically have three different operating modes: open access, closed access and a combination of both named…

QoS managing An important point with regard to providing QoS is to reduce signaling and interference. With this, operators can properly manage resources without such problems, in order to improve the services provided to users. In this new scenario, the traffic generated from the UE to the eNodeB is deflected by an IP network before reaching the mobile network. The transmission of a information packet over an IP network is susceptible to delays, so the femto-cell may experience problems for obtaining an immune base time to jitter. Operators should ensure the concept of QoS in femto-cells, the parameters of these…

The telecommunications network of an ISP (Internet Service Provider) is actually an interaction of various networks types, within LTE (4G) can be highlighted as an access network to the end user. The information flow reaches to the user through several infrastructures, on which the ISP carries data traffic, from this perspective, some necessary points will be discussed in order to ensure the Quality of Service (QoS) in such environments. From the point of view of LTE management, it is permitted to define profiles and classes of services, which are key points when negotiating QoS mobile requirements during the communication establishment,…
