Functions Implemented by RNC
Service function Besides the basic telecom services, ZXWR RNC can also implement the following
services: positioning service, R99, HSDPA, HSUPA, HSPA+ and MBMS service;
Interface signaling processing function The interface signaling processing function mainly refers to processing the control
planes of the interfaces, including: assigning and releasing of the radio accessbearer, security mode control, logical operation and maintenance of Node B,synchronization, sending and receiving NAS message, system message broadcast,paging support;
Radio Resources Management The Radio Resource Management (RRM) function can be used to assign the air
interface resources, guarantee the QoS of the system, obtain the planned coverageand expand the capacity. The RRM includes:Radio measurement, access control(AC), load control (LC), power control (PC), packet scheduling (PS), handovercontrol (HC) and dynamic radio bearer control (DRBC);
Data Transmission The data transmission function includes user data transmission and signaling data
transmission. It is used to complete the processing of Iuup/RLC/MAC/FP, dataencryption, Mac-C and Mac-hs flow control. It provides the end-to-end datatransmission for the users.

Resource Shelf: BUSN, BGSN
Control Shelf: BCTC
The resource shelf provides client processing pool and Iu interfaces
ZXWR RNC has two types of resource shelves: one is the 100M resource shelf based on BUSN, and the other
one is 1000M resource shelf based on BGSN.
The control shelf containing ROMB resides at layer 2 service junction box on rack 1,
and the rest of the control shelves can be put at any layer of the rack. The control shelf is responsible for
system signal processing,operation and maintenance processing, and clock.
Switch Shelf: BPSN
The switch shelf provides level 1 IP handover platform,
which is utilized by multi-resource shelf, interface shelf and user volume expansion .
Interface Shelf: BPSN
The interface shelf provides Iub interfaces for the system. The Service data are transmitted to the resource
shelf via the switch shelf.
ZXWR RNC has two types of interface shelves: one is the 100M interface shelf based on BUSN, and the
other one is 1000M interface shelf based on BGSN.

Configuration Rules for Boards on Resource
Shelf/Interface Shelf
Differences between the Iub access functions of the interface shelf and the
resource shelf: The interface shelf and resource shelf both can provide Iub access.
When the Iub access uses the high-speed IP interface (only Ethernet
interface is supported currently) , the Iub interface is directly connected to
the resource shelf.
When the Iub access uses ATM interface or low-speed IP interface, the
access is processed by the interface shelf, And the service data are sent
to the resource shelf via the switch shelf. Definition of 1000M Interface Shelf
The 1000M Interface Shelf is a type of shelf that is only used for Iub
access.
Functions of 1000M Interface Shelf Provides ATM access for the Iub interface.
Provide IP access (high speed IP interface) for the Iub interface.
Note: Low-speed IP access usually refers to that the physical layer uses E1/T1
or the CSTM-1 and the upper layer is IP layer.
High-speed IP access usually refers to IP Over Ethernet.

ZXTR RNC supports multiple IP UTRAN networking
modes. Based on the type of the
transmission network and
the interfaces, the IP
UTRAN can adopt the
following networking
modes:
IP UTRAN networking based
on the ATM network.
IP UTRAN networking based
on the SDH network. IP UTRAN networking based
on the IP MAN.
Hybrid mode, i.e. the split
transmission mode.

IP UTRAN Networking Based on SDH Network
The RNS equipment is connected to the SDH network via the E1 orchannelized STM-1 interface. The SDH network implements transparenttransmission. There is no need to add routers and switches.
Usually, the traditional operator has its own SDH network and rich resources,so it is suggested to construct the IP UTRAN network based on the existingSDH network.

Split Transmission of IP UTRAN
When bearing the traffic between the RNC and NodeB, the Iub interface assignsdifferent physical mediums and bandwidths for the large-traffic NodeB according to theservice types.
Data services (e.g. HSDPA) should be transmitted via high-speed interfaces (e.g. FE) inorder to reduce the cost of networking, because they have huge peak traffic, largedynamic range of peak-to-average ratio and frequent traffic burst,
Signaling, voice, operation & maintenance services should be transmitted via E1/T1 links,because they need to be processed in real time.

As for the transmission mode of ZXWR RNC, the Iub
transmission to each Node B can be configured
independently.
Based on the flexible configuration of the transmission
interfaces of ZXWR RNC, it is easy to implement
multiple IP UTRAN networking modes.
The site with rich TDM transmission resources
can choose to transmit all the services via the
TDM network.
The site with rich IP data network can choose
to transmit the services via IP network.
If the site has both transmission resources, it
can choose to transmit the session services via
the TNM network, and the other services via
the IP data network.
