  • 1 Introduction 2 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Introduction  Radio Measurement Statistics (RMS) assisted frequency plan is a service introduced by Alcatel.  RMS feature is Introduced by B7 software Release.  It’s a powerful method for frequency planning as it’s based on real field measurements, not predicted model.  For this frequency planning method, users mobiles are acting as measurement equipment.  The RMS feature has also more benefits for optimization and network performance analysis, like voice quality. 3 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • 2 RMS Feature 4 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • RMS Feature  RMS feature added value: • Detection of interfered frequencies and interferers. • Assess quality of the cell coverage. • Assess radio link quality. • Evaluate the voice quality.  RMS results usage: • Frequency planning. • Optimization and detection of the radio origin of a bad QoS in order to optimize consequently the network parameters. 5 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • RMS Feature  RMS creates statistics on the network QOS: Based on field measurements. • Measurements are performed by each mobile during a call. •  Radio related statistics reported per TRX: • • • • • • • On neighbor cells (C/I). On downlink and uplink quality & level. On number of consecutive bad speech frames (BFI). On Radio Link Counter (Uplink only). On Path Balance and on Timing Advance. On Power and number of channel seizures. On Voice quality indicators. Used in FP  RMS Reporting period shall be provided from one hour up to 24 hours.  During the observation period, the BTS stores all the statistics results reported by the mobiles.  At the end of the observation period, the BTS builds a report (binary files) and sends it to the OMC-R through the BSC. 6 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • RMS Feature  The RMS feature reports on request a C/I vector between each cell and its neighbor cells.  Each C/I vector contains for user defined C/I intervals the number of measurement samples over a measurement period.  This information can be used to create a network wide interference matrix.  Interference matrix is one of the important inputs to the RNP tool.  RMS enters the frequency planning process through interference matrix.

  • 5 Dummy Neighbors Concept 17 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Dummy Neighbors Concept MS will measure only defined neighbor BCCHs  Cell close to serving cell but not using neighbor BCCHs are: Serving cell Neighbor cell  not reported  not contributing to overall interference matrix Other cells  RMS interference matrix is not reflecting the complete network interference Some interferer BCCH frequencies are not reported 18 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Dummy Neighbors Concept Problem:  Measurements are done only for declared neighbors in OMC-R. This leads to:  Interferer BCCH frequencies, which are not neighbors, are not measured.  RMS interference matrix is not reflecting the complete network interference:  Report only for declared neighbors.  Interference is existing but is not measured. Solution:  Generate Dummy neighbors for RMS measurements.  Dummy neighbors can be:  Real cells.  Logical cell with the BCCH frequency to be measured (Dummy Cells). 19 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Dummy Neighbors Concept Solution: Add ‘Dummy Neighbors’ !!! ? 20 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Dummy Neighbors Concept RMS measurements with dummy neighbors  All cells close to the serving cell are measured and reported to the OMC-R  Target is to measure as many different BCCH as possible  Dummy neighbors: Serving cell Neighbor cell Dummy neighbor cell  Not real neighbors  Different BCCH than:  Serving cell.  Neighbor Cells. 21 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • 6 Dummy Neighbors Algorithm 22 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Dummy Neighbors Algorithms Two main algorithms implemented and used by A9155v6 frequency planning tool.  The two algorithms are: • Narrow band BCCH algorithm. • Wide band BCCH algorithm.  Narrow band algorithm has two sub-cases: • BCCH with dedicated band. • No dedicated band for BCCH. The common idea is to make mobile measure many frequencies as possible. 23 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Dummy Neighbors Algorithms Narrow BCCH Band Approach ( BCCH band <= 32 )  Assumption: All BCCHs are from a specific dedicated Frequency Block  Goal: Measuring all BCCHs means measuring of all Cells possible  Method: Add External Cells with BCCH between B1 – B32 and create HO relations for them, but inhibit HO by parameter setting (i.e.. HO_MARGIN = 127 ) OMC External Dummy Cells and Dummy HOs BCCH B1 # External cells BCCH B2 BCCH B3 = BCCH B4 BCCH B5 # BCCH Frequencies BCCH B6 ... BCCH B32 24 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Dummy Neighbors Algorithms Wide BCCH Band Approach ( BCCH band >= 32 )  Assumption:  Goal:  Method: BCCHs are homogenous distributed over a band > 32 Measuring cells in consecutive packages starting with the most important  Setting up HO relations to real existing cells in the network.  Inhibiting HO execution by parameter setting ( for instance HO_MARGIN =127  Selection of important cells by using other criteria ( for instance Predicted IM). Basic RMS Measurments 25 | RMS Frequency Plan | December 2006 Basic RMS Measurments All Rights Reserved © Alcatel-Lucent 2006, December ).
  • Dummy Neighbors Algorithms  Interference probability for cells with the same BCCH  The RMS C/I statistics cannot be applied to neighbor cells using the same BCCH frequency as the serving cell  In this case, mobiles are not able to perform measurement of the neighbor cell received level and they cannot decode the BSIC information. Cell C Cell D Cell F Cell A Cell B Cell E Cell G Cell A & Cell B have the Same BCCH 26 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Dummy Neighbors Algorithms  If the Probability of interference is as follows: • Pint (A, F) = 0.5 • Pint (A, E) = 0.3 • Pint (A, C) = 0.1 • Pint (A, D) = 0.05 • Pint (A, G) = 0.05  The goal now is to evaluate the interference probability between cell A and cell B (Pint(A,B))  The principle is to recreate the list above not related to cell A itself, but to all the neighbor cells of cell A. • Average [Pint (All neighbors of cell A, C)] = 0.4 • Average [Pint (All neighbors of cell A, F)] = 0.3 • Average [Pint (All neighbors of cell A, B)] = 0.2 • Average [Pint (All neighbors of cell A, D)] = 0.1 • Average [Pint (All neighbors of cell A, E)] = 0.1 • Average [Pint (All neighbors of cell A, G)] = 0.05 27 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Dummy Neighbors Algorithms  So, in this list, cell B must be between cell F and cell D and its interference probability  It is estimated to be in the middle of the two others that is: Pint (A,B) = [Pint (A,F) + Pint (A,D)] /2 = 0.275  As a result, it is possible to obtain the complete list of interference probability related to cell A, as shown below: • Pint (A, F) = 0.5 • Pint (A, E) = 0.3 • Pint (A, B) = 0.275 • Pint (A, C) = 0.1 28 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • 7 Precautions 29 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Precautions  Before the RMS Data Collection.  Re-engineering is Recommended . • This step aims to minimize the overshooting as much as possible by adjusting the tilts & Azimuth.  Neighbor Cleaning. • In some cases (especially when having a dual band network) the number of HO relations per cell is found to be high. • Cleaning can be based on the T180 counters. • To ensure that there are vacant places for the creation of Dummy Neighbors. 30 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Precautions  During RMS Data collection.  Freeze Roll out of New Sites. • The network concerned areas should be assured to be Freezed (No roll out) through the entire period of the RMS data collection.  Total Freeze on the Network. • No BCCH frequency Change. • No addition or deletion of HO relations. 31 | RMS Frequency Plan | December 2006 All Rights Reserved © Alcatel-Lucent 2006, December
  • Precautions  Inhibition of the HO attempts towards Dummy Neighbors : Parameters per adjacency with a dummy neighbor : HO_MARGIN HO_MARGIN_DIST HO_MARGIN_QUAL HO_MARGIN_LEV L_RXLEV_CPT 32 | RMS Frequency Plan | December 2006 = = = = = 127 dB 127 dB 127 dB 127 dB -47 dBm All Rights Reserved © Alcatel-Lucent 2006, December
