Configuring Transport over IPIub interface protocol


Configuring Transport over IP


Configuring Transport over IPConfigure the PPP, MP, PPPoE, and Ethernet IP In a single transport mode, configure one type of transport links. In hybrid transport mode, configure E1 and FE transport links.For E1 links, configure PPP or MP.For FE links, configure PPPoE or Ethernet IP. IP hybrid transmission


Configuring Transport over IPConfigure the IP routeIf the gateway type of the route is Ethernet, the next hop address and the gateway IP address must be in the same network segment If the NodeB and RNC are in layer 2 networking The IP addresses of the FE ports on the NodeB and RNC should be in the same subnetIf the NodeB and RNC are in layer 3 networking The next hop address is the IP address of the router that connects to the NodeB or the IP address of the port on a layer 3 switch.The destination address of packets has the corresponding route in the routing table.The corresponding link layer address can be found only when the router specifies the next hop IP address (gateway).Configure just one route to the same destination address.


Configuring Transport over IPConfigure the QoS To configure signaling and OM priorities IP Quality of Service (QoS) is an IP network capability to provide specific services over the IP network that uses mutiple bottom-layer network technologies such as MP, FR, ATM, Ethernet, SDH, and MPLSIP QoS supports the switching between the IP precedence and DSCPThe IP QoS configuration is flexible


Configuring Transport over IPConfigure the NBAPConfigure destination IP address & local IP interface The IP routes for destination addresses are availableOnly one NCP can be configured Several CCPs can be configuredThe destination IP address, local port number, and destination port number of the NCP/CCP on the same link should be differentWhen you choose one NCP/CCP on the NBAP tab page, the corresponding links are displayed in the middle part, and the corresponding routes are displayed in the lower part


Configuring Transport over IPConfigure the OMEnsure that the route from the LMT (or M2000) to the subnet is configuredOnly one OM channel can be configuredIf you choose an OM channel in the upper part of the OM tab page, the corresponding route is displayed in the lower part The destination IP address of the OM channel is the IP address of the NodeB LMT or M2000


Configuring Transport over IPConfigure the IP pathThe IP routes for destination addresses are availableThe IP path does not have bandwidth limit. Therefore, to configure the IP path is to differentiate service priorities. When the HSDPA service is transmitted, configure two IP paths with different path IDs. The two paths correspond to R99 service and HSDPA service. There is no service priority at the NodeB side. Therefore, configure one IP path at the NodeB sideIf you choose one path on the upper part of the IP path tab page, the corresponding links are displayed in the middle part and the corresponding route is displayed in the lower part

Parameter DescriptionIUB Clock Source: If the NodeB reference clock source is an Iub clock source, you need to determine from which link the 8 kHz clock signal is extracted.Parameter DescriptionRRU Chain No.: Unique number of the RRU chainChain Type: Value range: chain, ring Head Port No.: The number of the HBBU/HBOI CPRI port number where the RRU chain head is located.Break Position 1: Break position 1 for the new RRUIf it is set to OFF, the new RRU is located at the end of the chain. Tail Port No.: The number of the HBBU/HBOI CPRI port where the chain tail is located.This port number is valid only when it is an RRU ring. Break Position 2:Break position 2 for the new RRU.This break position is valid only when it is an RRU ring. A HBBU provides 8 E1/T1 PortsPort 0 and 1 support fractional ATM work modePort 0,2 and 3 support timeslot cross technique (port 0 is fixed to connect with RNC, while port 2 and 3 are connect with lower level NodeB)Port 0~7 support IMA and UNI work modeE1 ports are used to connect with the lower level equipment in CES

The UNI mode is an ATM transport mode in the TC sublayer of ATM physical layer. In UNI mode, ATM cells are directly mapped to the valid timeslots of a single E1/T1. This mode is a non-IMA E1/T1 mode for ATM cell transport.Figure A-4 shows the mapping of the ATM cells to E1 timeslots in UNI mode. As shown in the figure, the 53 bytes of an ATM cell are sequentially filled in 53 timeslots of an E1. Note: timeslots 0 and 16 of the E1 do not bear any ATM data. 125us=1/(2*4000)256bit=32*8bitThe Inverse Multiplex on ATM (IMA) mode is an ATM transport mode in the TC sublayer of ATM physical layer IMA flexibly combines several narrowband transport links to transport high-speed ATM cell streams, which is referred as inverse multiplex on ATM. By this way the existing narrowband transport links, especially two Mbit/s links, can serve broadband ATM transmission. IMA also enhances transmission reliability.

As shown in Figure, several ATM cells, IMA control protocol (ICP) cells and filler cells form an IMA frame. The length "m" of the frame is defined when IMA group is configured. In IMA mode, the mapping of cells to each physical link transmission frame, such as E1/T1 link, is similar to that implemented in UNI modeAn NDTI supports eight E1/T1 links. Each link can be configured as UNI link or IMA link. An IMA group contains up to eight E1/T1 links. The E1/T1 links in an IMA group must belong to the same NDTI. The Fractional ATM mode is an ATM transport mode in the TC sublayer of ATM physical layer. In fractional ATM, ATM cells are transmitted using some of the 32 E1/T1 timeslots. AMT cells are mapped to some of the E1/T1 timeslots, instead of all of the timeslots. At the peer end, the ATM cell stream is recovered from these E1/T1 timeslots. The timeslots that are unavailable for ATM cell transmission can transmit other information.NDTI No.0 E1 is directly connected to RNC or the upper level NodeB.No.2 or 3 E1 of the same NDTI is connected to 2G BTS or monitoring device Timeslot across channel affects the PM sublayer of ATM physical layer. Parts of the timeslots in BTS38XX NDTI E1/T1 port 2/3 are connected with those in E1/T1 port 0. The data transported on these timeslots of the NDTI E1/T1 port 2/3 are directly switched to the corresponding timeslots in NDTI E1/T1 port 0 and then sent out. On the receipt end, the data on the timeslots of the port corresponding to NDTI E1/T1 0 are switched to the port connecting with 2G BSC. The timeslot across channel serves to transport environment monitor data or 2G equipment data.
