Control functions processing: Mandatory for centralized functions, one card in two modules (2N)
External interface processing: Min. two per configuration for transport (SN+)
Cell specific services processing: Number depends on the coverage/connectivity, (N+M)
User specific services processing: The rest of the processors (violet colour) are shared between user specific UP and CP by SW, (SN+)

direct IP/Eth interfaces in mcRNC front panels in each module
IP transport over PDH/TDM networks efficiently over E1/T1/JT1
Multilink-PPP (RAN1878)
support in BTS in RU30, aggregation in the IP router
improved transport efficiency for packet traffic over E1/T1/JT1
Efficient transport for small IP packets in RU30 (RAN1886)
Multiple IP interfaces from BTS in RU30 (RAN1317)
load sharing, traffic separation
Multicontroller_RNC_0707909.ppt
Solution consists of Flexi WCDMA BTS using features
RAN74: IP based Iub
and IP router terminating TDM layer and ML-PPP
Operator benefits
IP is the single transport technology
Protects previous investment in TDM infrastructure (e.g. microwave radios)
End-to-End solution for decoupling cost from capacity Enabling cost-efficient backhaul of HSPA peak rates
Ethernet
RNC
Feature ID(s): RAN1886
With 3GPP compliant Iub/IP protocol stack each voice frame is transported in its individual UDP/IP packet, resulting in low transport efficiency with a voice dominated traffic mix
This feature introduces a multiplexing scheme in BTS and RNC, which allows transporting multiple voice frames within the same IP packet on Iub & Iur
The multiplexing itself is transparent to the traversed transport network, i.e. intermediate routers see only a normal UDP/IP packet
This allows to improve transport efficiency by up to 50%, leading to reduced bandwidth needs and thus lower costs
Transport bandwidth optimization for small IP packets,
e.g. in case of voice frames
