AAL Switch isn't for commercial use. Compared with ATM Switch, AAL is more complex and less efficient. The
feature “WRFD-050106 AAL2 Switching Based Hub Node B” is not recommended for commercial use.

RNC
When the hub Node B transmission is applied, the RNC can be connected to more Node Bs with only
one physical port. In this case, the RNC may send out data with a high bit rate, and if all the data is
sending to one Node B, for example, Node B 3 in upper figure, congestion may happen at Node B 2 and
data will be lost accordingly.
all PVCs connected to one Node B are considered as one virtual port; if one Node B is a hub Node B, all
PVCs connected to it and PVCs connected to its leaf Node Bs are considered as one virtual port only.
The RNC monitors the buffer occupancy status of each virtual port to avoid data loss.

9. Fractional ATM Function on Iub Interface
This feature enables ATM cells to be transmitted on some timeslots of the E1/T1 bearer and other data
to be transmitted on other timeslots. It applies to the scenario where 2G and 3G data is transmitted
simultaneously.
Benefits :
Sharing of transmission links between 2G and 3G systems.
Reduced time in market at initial rollout.
Savings of transmission costs when co-site 2G and 3G.

12. Fractional IP Function on Iub Interface
In fractional IP, IP packages are transmitted using some of the 32 E1 timeslots. IP packages are mapped
to some of the E1 timeslots, instead of all of the timeslots. At the peer end, the IP package is recovered
from these E1 timeslots. The timeslots that don’t use for IP package transmission can transmit other
information.
Benefits :
Sharing of transmission links between 2G and 3G systems.
Reduced initial rollout Time in market at.
Savings on transmission costs when co-site 2G and 3G.

13. Hybrid Iub IP Transmission for Smooth
Evolution
SDH
In hybrid mode, the real-time services such as voice and streaming data services are transported on IP
over E1/STM-1, while non-real-time services such as interactive and background services are
transported on IP over Ethernet. Iub user plane traffic and Iub NBAP signaling can be carried over
hybrid networks on backup mode. When one path fails, all the new coming traffic is carried on another
path
Benefits :
This feature enables the transmission of real-time services and non-real-time services on different
paths to meet the requirements of UMTS services, it could save OPEX on Iub transmission, especially
when deploying HSDPA/HSUPA service.

14. ATM/IP Dual Stack Node B
RNC can support IP Node B and ATM Node B simultaneously
Node B can support ATM and IP dual protocol
Benefits :
This feature helps protect operator’s investment and provide flexible networking, smooth upgrading
from ATM transmission to IP transmission on Iub interface.

17. Dynamic Bandwidth Control of Iub IP
Applied to the following networking scenarios
1. ADSL and ADSL 2+
2. IP traffic convergence
Based on Huawei
PRIVATE protocol
The principle of IP PM : One end sends
FM (Forward Monitoring) message
periodically, the other end echoes PM
with BR (Backward Reporting) message
as soon as it receives FM message.
With FM and BR, packet loss rate of link and jitter could be calculated accordingly, When the packet loss
rate or jitter increases, the available bandwidth decreases. When the packet loss rate or jitter
decreases, the available bandwidth is increases.
