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 access bearer, 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 coverage and expand the capacity. The RRM includes:Radio measurement, access control (AC), load control (LC), power control (PC), packet scheduling (PS), handover control (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, data encryption, Mac-C and Mac-hs flow control. It provides the end-to-end data transmission for the users.

Key Description

RST Reset switch

RUB board is the control plane processing board of the RNC. Its main function is to

process the radio user plane protocols. RUB (VTCD physical board): provides 1 FE interface on the rear board user plane. RUB (VTCD/2 physical board): provides 1 FE interface and 1 GE interface on the rear

board user plane.

PWRD board is the power distribution board of the RNC. Its main functions include:

Provides -48 V power supply for the fans and shelves in the rack. Monitors the power supply and environment of the rack and sends

alarms. Monitors and controls the fans on the rack.

PWRD board reports the monitoring information to the ROMB board via the RS485 interface and gives indications via panel indicators of power distribution box.

Peripheral Monitoring Unit - ALB (Alarm Box)

ALB is the unified alarm box for the peripherals. Its main functions include: Sending alarm messages. Alarm sound prompt. Alarm indicator prompt. Showing the alarm on LCD. Querying the alarm statistics. Automatic mute.

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.

Network Management Networking Scheme

Suggestions for Usage: Ordinary users can use the NetNumen network management system. Advanced users can use the OMM network management system.

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.

RNC

ATM TDM

Node B

IP

IP UTRAN Networking Based on SDH Network

The RNS equipment is connected to the SDH network via the E1 or channelized STM-1 interface. The SDH network implements transparent transmission. 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 existing SDH network.

IP UTRAN Networking Based on IP MAN

The RNC and Node B are directly connected to the MAN via the edge router by GE/FE interface.

GE/FE

FE

IP MAN

The IP Man can be an IP backbone network that uses high-speed routers as the core equipment, or a MAN using MPLS technology, or a MAN uses the MSTP with embedded RPR technology.

In the future, the UTRAN services transmission via IP MAN will become the main IP UTRAN networking mode.

RNC Node B

Split Transmission of IP UTRAN

When bearing the traffic between the RNC and NodeB, the Iub interface assigns different physical mediums and bandwidths for the large-traffic NodeB according to the service types.

Data services (e.g. HSDPA) should be transmitted via high-speed interfaces (e.g. FE) in order to reduce the cost of networking, because they have huge peak traffic, large dynamic 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.
