Self-optimization of LTE networks utilizing Celnet Xplorer

Abstract: In order to meet demanding performance objectives in Long TermLong Term Evolution standard. Through its E-UTRAN, LTE is expected to substantially improve end-user throughputs and sector capacity and reduce user plane latency, bringing significantly improved user experience with full mobility.

“…Self-optimization have already been studied in 2G and 3G networks, typically with the objective of improving radio coverage and channel capacity, however in recent years, there has been an increasing interest in the SON paradigm applied to mobility and location management of wireless networks [9]. The authors in [15] present a self-organized TAL mechanism to reduce the signaling overhead of a network of femtocells.…”

“…Call intensity factor (probability that a UE has to be paged) In SON, there are software clients such as data collectors (DCs) which collect data to monitor network performance [9]. The optimization and new configuration decisions are based on the collected data, however no data is collected for the location and mobility behavior of idle UEs, which are the focus in the study of location management.…”

“…Alcatel‐Lucent has developed multiple commercial products based on IP packet capture data. Two such products are Celnet Xplorer [4] and Wireless Network Guardian (WNG) [1]. Both products use dedicated hardware placed within the IP network serving a switching system to continuously capture IP packet traffic.…”

“…In the daytime, base stations are usually in normal load and are not capable for on-off control frequently; on the contrary, in the night time, number of users that require data traffic are far more small than that in the daytime, so there exists the chance to shut down the idle base stations according to the actual status of the data traffic. This is the most effective method to reduce energy consumption due to the architecture of the wireless network [5, 6]. In cooperative networks, energy consumption in backhaul transmission becomes critical recently.…”
