Dual Cell Procedures



For internal use

2 © Nokia Siemens Networks Loh

Introduction

• Define procedure to define Dual Cell procedures

Objective

• UARFCN F1 (10622), F2 (10597), F3 (10572)

• Preferred service F1 (R99), F2 (HSPA), F3 (HSPA)

• Preferred layer F1 (non-data card UE), F2 (data card UE)

• Local Cell Group F1 (1), F2 (2), F3 (2)

• Inter-frequency handover F2 to F1 and F3 to F1. Define co-site F1 ADJI on F2 and F3 cells.

• Define co-site ADJG on F2 and F3

• RT FMCS on F2 and F3 to FMCS 11 (RSCP -70/-60, EcNo -10/-7)

Key Points



For internal use

•Local Cell Group should be F1 (LCG2), F2 (LCG1), F3 (LCG1)

•CE ratio should be LCG1 (70%), LCG2 (30%)

•WBTS license should be installed accordingly

•Transmission logical bandwidth for 42Mbps sites (90Mbps), 21Mbps sites (45Mbps)

•CE allocation 636 for 42Mbps sites and 492 for 21Mbps sites

3rd Carrier Strategy



For internal use


•Layer F1 is set to non-HSPA layer (F1 is the preferred overall layer)

•Layer F2 is set to HSPA layer (F2 is the preferred HSPA layer)

•Layer F3 is set to HSPA layer

F1 – R99

F3 - HSPA

F2 - HSPA

Carrier Layering

•User creates PDP session on F1

•DRRC HSDPA direct the call from F1 to F2 (or F3 if F3 is the more attractive cell)

•User will be camping in F2 or/and F3 based on HSPA layer load balancing and

dual cell feature

Zain Data Card User

•User creates PDP session on F1

•DRRC HSDPA direct the call from F1 to F2 (or F3 if F3 is the more attractive cell)

•User will be camping in F2 or F3 based on HSPA layer load balancing

•User will perform Inter-frequency handover from F2/F3 to F1 when voice call ismade (RSCP -70, EcNo -10)
