LTE 1800 has highest priority in layering. All UE with supported LTE band will be pushed to camped in LTE layer.. Voice Service in LTE layer LTE will be served by CSFB to UMTS layer. layer. Data Service can be handover to UMTS after LTE out of coverage with good end user experience in DC HSDPA.
U900 : HSPA+R99
DCS1800 GSM900
UMTS2100 and UMTS900 are configured with total 4 carriers on co-lo sector. Traffic in all carriers will be balancing with Call setup re-direction via MBLB. Main capacity layer in UMTS is UMTS2100, while UMTS900 will be used for blanket coverage layer. UMTS2100 (F1) will be used for priority layer as CSFB from LTE. If U900 has become seamless coverage, CSFB from LTE will use U900 as highest priority. Spectrum re-farming on DCS1800 to introduce LTE. Aim to keep traffic in 3G as much as possible due to the reduction on 2G bandwidth. GSM900 can uses EGSM frequency after these spectrum clear from other operator ‘s interference.

Existing U2100 consist of 3 carrier with mixed voice and data service ( HS+R99) for each carrier
U900 will be used as similar service layer as U2100 with mixed voice and data service (HS+R99)

Power Offset Measurement in Idle Mode • U2100 -> U900 cell reselection
Interfrequency measurement is delayed until Ec/No < -14 dB (Qqualmin=-18 dB, Sintersearch=4 dB, Qrxlevmin=-115 dBm)
AdjiQoffset1 and AdjiQoffset2=0 since U900 is stronger
AdjiQrxlevmin=-101 dBm to prevent reselecting to U900 cell with good Ec/No but poor RSCP
• U900 -> U2100 cell reselection
Interfrequency measurement is triggered early at Ec/No < -6 dB (Qqualmin=-18 dB, Sintersearch=12 dB)
Measurement offset is used to favor U2100 (AdjiQoffset1 and AdjiQoffset2 = -10 dB)
Min quality is used to ensure target cell quality and to avoid pingpong at the edge of U2100 coverage (AdjiQqualmin = -18 dB, AdjiQrxlevmin = -115 dBm)
Redirection via Multi Band Load Balancing •
The Multi-Band Load Balancing (MBLB) feature includes 4 components: • Redirection during RAB setup: either first RAB, or AMR RAB for a UE which already has an NRT RAB blind handover • Redirection during the transition to CELL_DCH: state transitions from CELL_FACH, URA_PCH or CELL_PCH does not include transition from RRC Idle mode blind handover • Redirection after detecting inactivity in CELL_DCH: inactivity detected for last active PS NRT MAC-d flow inter-frequency handover with compressed mode measurements • Redirection due to Mobility: addition of cell to active set which has different preferred layer definitions inter-frequency handover with compressed mode measurements – –
