The instructor should briefly explain the different features and parameters. This must be up to the instructor’s “ear” to feel what features are particularly interesting for this course. Point also out that during the course the students will have access to all User Descriptions of the features. This information could be valuable for solving the radio tuning cases in the course. It is not possible, in the limited time available, to discuss all radio network features in detail. This must be referred to the Radio Network Feature course, LZU 108 3704. 3.3 Exercise Guide Exercise 3, 4, 5, 6 and 7 3.4 Case Guide Tuning Case 1, 2 and 3 There exist three tuning cases described in the case document. To collect cell parameter for the cases the BSC simulator can be used. The instructor may of course also use either training BSC or OSS/CNA to collect cell parameters. This requires that the instructor has defined all necessary data in either the BSC or OSS/CNA. During the tuning cases it is recommended to let the students work in groups of two to four students. Let all groups present their solution on the white board, discuss the different solutions and then try to agree on the best way of improving the problem situation described in the case study. A suggestion to solutions to the cases is to be find in the document 03815-LZU 108 3298. Before starting each of the tuning cases be sure that you have completed the teaching of the relevant subjects. 3.5 Summary This module treats a selection of the radio network features. It can be looked upon as a summary of the radio network features course. In particular locating is important to be able to understand parameter discussions that follow.

What are counters (software entities belonging to function blocks), what type of counters exist (event counters, level counters) and when are they activated? So, you collect data, store in a database, process it and present it, and although the last two activities are also possible using STS and measurement programs (OMS), external spreadsheets, such as those in OSS, give us much more options. Explain how counters are stored as peg counters and status counters, how they are collected in object types (show e.g. BSC object types and counters in the object type CELLTCH), and that you need to employ “user formulas” to get something useful from them (show e.g. user formulas for average TCH traffic level, TCH congestion, dropped TCH congestion, and successful handover rate). 4.2 Exercise Guide 4.2.1 Exercise Exercise 8 4.3 Cases Case 4 In this case the students will analyze counters data given in the “case_4.xls” data sheet. For part d) they shall use the BSC Simulator, case 4. Case 5 In this case the students will analyze counters data given in the “case_5.xls” data sheet. For part b) they shall use the BSC Simulator, case 5. 4.4 Summary This module is an introduction to counters, user-formulas and some of their interpretation.

It is a good idea for the instructor to be familiar with the User Description Radio Network Statistics where all formulas and counters can be found that are discussed in this chapter. Be sure to underline that STS is not the only tool available for tuning activites related to GPRS/EGPRS. In slide 55; there is an exercise that asks the students to get the formulas that is described in the table. Give the students a few minutes to figure out what they are and then analyse each cell to find out what might be wrong. 6.3 Exercise Guide Exercise 9 6.4 Summary This module discusses tuning and optimization of GPRS and EGPRS.
