    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.

    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.

    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.

    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.

    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.
