TCP Service Differentiation | Solution for High Congested Cells where resource addition delay

With this functionality enabled, Packet Data Convergence Protocol (PDCP) layer is monitored for TCP traffic. From the moment it is detected, the BTS starts measuring volume of TCP data (only TCP packet with size equal or bigger than the LNCEL Minimum TCP packet size (minTcpPacketSize) parameter are considered for this measurement). Two thresholds are defined Lower and Upper for UL and DL both After reaching lower threshold, the scheduling bias is applied, resulting in a boost of data transfer. After reaching upper threshold, the bias application is stopped, and data transfer is not boosted anymore

Trial Result 

1. Data Traffic Increased by 1%

2. Volte Traffic Increased by 8%

3. %Cells CQI<8 reduced by 6%

4. %Cells RRC SR>98% increased by 5%

5. %Cells RAB SR>98% Increased by 3%

6. %Cells PS Drop>0.9% reduced by 31%

7. %Cells with DL User Throughput<2Mbps reduced by 17%

Pa Pb in LTE and its impact on User Throughput

Downlink signals are  made up of many different components. For example, Reference Signal, PDCCH, PDSCH etc. The RS power and the SCH powers are key RF optimization parameters that influences the cell coverage. It is set according to the cell size. The higher the setting, the larger the cell coverage  on the downlink, but leaves smaller power headroom available for other downlink signals  and channels. The relation between RS power and power on PDSCH symbols (includes type A and type B symbols), has to be defined and reported to the UE, in order for the UE to demodulate 16QAM and 64QAM.1 PDSCH type A symbols has only PDSCH RE’s, PDSCH type B symbols has mixed RS and PDSCH REs. Parameter PA sets the power of PDSCH type A RE relative to cell‐specific RS, PB sets the power relation between PDSCH type B RE, and PDSCH type A RE (ρB/ρA in 3GPP). The ratio of PDSCH EPRE to cell‐specific RS EPRE among PDSCH REs for each OFDM  symbol is denoted by either ρA or ρB according to the OFD

LTE Layer management Strategy and basic working [LMS] Unlock

LMS Insight Layer Management Parameter Optimization is important aspect & it is triggered when all possible optimization techniques for ensuring best experience to customers is exhausted in the current layer For Example in a typical 3 Layered cellular network, we have LTE layer (with a mix of TDD(2.5GHz) and FDD(1.8GHz)), followed by WDCMA Layer (WCDMA2100) & then the GSM layer (1800 MHz Before actually working on Layer Management Parameter Optimization, we need to ensure Traffic Balancing within the layers is proper & as per recommendations to give desired customer experience Pre-requisite Actions Ensure below checks before moving to optimize the Layer Management Thresholds for a cell. Traffic balancing within layers should be optimal -  if network has 2 layers of LTE i.e. both TDD-20 MHz & FDD-5 MHz, Traffic distribution for collocated cells with TDD/FDD should be 75:25 (TDD: FDD) or better. This is applicable to networks with 2 carriers of WCDMA as well where the tra
