Abstract
When discussing the deployment, optimisation and operation of mobile radio networks three principal characteristics have to be addressed. The first flavor is related to the network coverage and is largely independent of the specific system.
A number of contributions within COST 2100 have been dedicated to these coverage related aspects and are discussed in Sect. 10.1. The second flavor deals with the optimisation of the network, which depends critically on the standard. Section 10.2 is dedicated to the 3GPP networks and includes optimisation Techniques mainly for UMTS and presented in COST 2100, whereas Sect. 10.3 deals with the IEEE 802.16 (WiMAX) and IEEE 802.11 (WLAN). It has to be noted that the optimisation techniques introduced in these two sections are based on classical approach using input data available in radio network planning tools and are different from the approaches described in the Sects. 10.4 to 10.6, where optimisation makes use of real measurement values.
Section 10.4 deals with off-line processing of measurement data applied to 3GPP standards and describes how this data can be fed back to the planning process. The main focus is on traffic and mobility-related issues of second generation networks based on GSM and GPRS and points out also standard independent issues like consistency and integrity of the collected measurement data. The next step in the evolution of measurement-based optimisation is subject to Sect. 10.5 and introduces auto-tuning concepts which are applied mainly to UMTS and HSPA. Although using a higher degree of automation, these concepts still rely on the traditional planning process. Finally, Sect. 10.6 deals with self-organising networks (SON), where the collection of measurement data in the live network as well as the optimisation and configuration tasks are intended to be performed by the network itself circumventing classical planning and optimisation in the final step of this evolution.
