release compatibility principles Multistandard Mixed Mode (MSMM)

EOM and EOS dates for MSMM in a certain RAN release combination is determined by the earliest RAN EOM and EOS date according to the GSM/LTE/WCDMA RAN Life Cycle Roadmaps

After the MSMM EOM date for a certain RAN release combination, new RAN correction packages do not support MSMM in that release combination

Example: G12B EOM Dec 2013 W13A EOM June 2014 EOM date for MSMM config with BTS G12B + RBS W13A Dec 2013 W13A correction packages between Dec 2013 and June 2014 do not support BTS G12B + RBS

W13A MSMM configurations Depending on market deployment per release combination, EOM/EOS dates can be set

to earlier dates Note that the MSMM release compatibility principles concerns compatibility between

GSM BTS SW, WCDMA RBS SW and LTE RAN SW in MSMM RNC-RBS, BSC-BTS and OSS-RC compatibility according to RAN internal compatibility

statements


MSMM, EOM dates per release combination BASED on 18 months RAN release maintenance

SYNCHRONIZATION OF DIGITAL UNITS


Synchronization overview

Synchronization between DUs required due to strict timing requirements on CPRI

Synchronization between DUs provided with two options: From a GPS02 receiver

2 DUs can be synchronized Using a synthesized GPS signal GPS Out

1 DUW or DUL/DUS can synchronize 1 DUG 1 DUW can synchronize 1 DUL/DUS In Dual DUW configurations 2 DUG/DUS can be synchronized

The RUS uses the DU connected to the CPRI Port 1 as the timing reference

If the RUS detects that port 1 is not usable while 2 is, port 2 is used instead

10/15/20 MHz LTE uses the capacity

of 2, 3 or 4 carriers of 5 MHz

4 carriers can only be configured as one GSM

carrier each

4 carriers can be configured as GSM carrier or 1.4, 3.0 or 5.0 MHz LTE carrier or 1 WCMDA

carrier each


flexible power configurations Output Power for each RAN is allocated independently of

each other If the total configured output power exceeds the RUS

capability the configuration will be rejected by the RUS Maximum 6 dB difference between GSM carrier output

power and WCDMA/LTE output power HW specific output power limitations described in CPI

(RBS Configurations, 24/1551-LZA 701 6001*)

*RUS02/RRUS12 information not complete, planned for CPI in March


Feature recommendations

To optimize EDGE performance, the following GSM features are strongly recommended

Dynamic BTS Power Control, DTX DL, Reduced Power Level After Handover

Voice output power is then reduced to an optimum level, leaving maximum power for EDGE

PS Downlink Power Control recommended to reduce GPRS/EDGE output power

FIELD EXPERIENCE


Summary of live network resultsGSM+WCDMAGSM+LTE

GSM, WCDMA and LTE Key Performance Indicators have been monitored, e.g.

Speech Quality Speech Drop Call Rate Traffic Volume Packet Data Performance Handover Performance

All KPIs show good results Activation of Mixed Mode had no negative impact on end-user performance In traffic situations with high load, some impact may be experienced for

EDGE packet data throughput


More 3g CAPACITY through traffic migration 28% increase in the share of 3G

voice traffic in three weeks

Enabled by GSM and WCDMA mixed-mode at 900 band

Migrates traffic from GSM to WCDMA

Speech quality maintained in both domains

More spectrum and capacity for WCDMA

Higher smartphone user-experience through continuous 3G access

900Mhz

2100Mhz


Double Ps traffic volume

PS traffic volume doubled in three months Increased usage of service = increase customer satisfaction Capture more revenue from capped monthly subscriptions Enabled by:
