2 Introduction to Iub Satellite Transmission
Iub satellite transmission refers to the satellite-based connection on the Iub interface betweenthe RNC and the NodeB.
IntroductionDefinition
In general, the data between the RNC and the NodeB is transmitted on terrestrial transportnetworks that can be based on PDH, SDH, MSTP, ATM, or IP. In some remote areas, coastalislands, deserts, and uninhabited areas where terrestrial transport networks are unavailable ordifficult to deploy, satellite transmission can overcome this difficulty.
Purposes
Since satellite communication has many benefits such as larger coverage, minor influence bylandforms, good mobility for emergency communications, easy link leasing or deployment, andeasy bandwidth control, Iub satellite transmission makes the Iub interface easier to deploy.
Satellite communication, however, has demerits such as high costs in equipment and link leasing,and high delay. Therefore, the Iub satellite transmission is recommended only when terrestrialtransport is unavailable.

ImpactImpact on System Performance
The feature has the following impact on system performance.l Satellite transmission quality is liable to environmental conditions. Bit errors may lead to
bad quality in calls and data services, lower efficiency in transmission, or even call failures.l The delay of satellite transmission is higher than that of terrestrial transmission. Satellite
transmission usually brings about the Round Trip Time (RTT) in the range of 500 ms to700 ms. Long delay or RTT may cause slow call connections or voice delay and affect thedownloading of high-speed data services.
Impact on Other Features
None.
CapabilitiesNone.

Communications Satellite
The communications satellite usually refers to a geosynchronous satellite. The satellite orbits ata distance of 36,000 km from the earth and has an angular orbital velocity equal to the earthorbital velocity.
A communications satellite consists of the control system, communication system (antennas andrepeaters), telemeter system, power supply system, and temperature control system.
Earth Station
An earth station consists of the antenna system, transceiver, channel terminal (modem),communication control system, and power supply system.
NOTE
l The interface between an earth station and the RNC or NodeB should comply with the ITU-T G.703recommendations.
l The RNC or NodeB can communicate with the earth station through the E1 or channelized STM-1interface board. The E1 interface board is recommended.
l The RNC or NodeB and the earth station can transmit signals to each other in PDH or SDH ormicrowave mode.
l The RNC or NodeB supports fractional ATM or fractional IP technology for satellite communication.
The earth station can be a large- or small-scale station.
l A large-scale earth station, such as a large-scale national or international communicationstation, uses the large-aperture antenna to transmit high-speed data. A large-scale earthstation brings the high cost. User data should be converged on the earth station throughterrestrial communication networks before satellite communication.
l A small-scale earth station, such as a Very Small Aperture Terminal (VSAT), uses thesmall-aperture antenna. The equipment features low cost and easy deployment.

3.3 Networking for Iub Satellite TransmissionIn terms of reliability and delay, it is recommended that the star topology be applied to satellitetransmission on the Iub interface.
Iub transmission links can be set up in the satellite network in three ways.
Leasing Existing Large Earth StationsIf links provided by the existing earth stations are leased, it is not necessary to take into accountthe networking for satellite transmission or to manage satellite equipment. Therefore, servicelaunch can be speeded up, but the networking is restricted by the locations of earth stations.
Utilizing Existing VSAT SystemsNew sites are set up in the existing VSAT systems. This saves costs in routine management andmaintenance of the VSAT system, but the bandwidth is limited. This way is applicable to small-scale networks.
Setting Up New VSAT SystemsSetting up new VSAT systems enables clear network structures and easy capacity expansion,but it requires heavy investment on a lump-sum basis.
In general, NodeBs in satellite transmission mode are usually deployed in remote areas wherethere usually might be no large earth stations nearby. In addition, the bandwidth requirement ofthe remote base station is not very high. Consequently, the VSAT system is a suitable choice.Figure 3-2 shows the VSAT system on the Iub interface.
Figure 3-2 VSAT system on the Iub interface
3.4 Bands for Iub Satellite TransmissionThere are two typical bands for satellite transmission on the Iub interface. A proper band shouldbe selected for satellite transmission, depending on climates in different regions.

Compared with terrestrial transmission, the Round Trip Time (RTT) value on the Iub interfacein satellite transmission mode increases by 500 ms to 700 ms. Consequently, the Uu interfaceRTT value carried on the Iub interface increases by 500 ms to 700 ms. The optimum Uu and Iubparameters should be used in this environment.
If the Iub satellite transmission is enabled, the RNC provides default values of the followingparameters for the NodeB using satellite transmission:
l Load Monitor (LDM) and Load Control (LDC) parameters
l Optimum parameters related to the sliding window size and timer of the RLC at the datalink layer
l Optimum parameters of the FP transport synchronization timer
l Optimum activation time of radio links
l Optimum outer loop power control parameters (to prevent voice and data quality fromcontrol hysteresis)
l Constraining the handover procedure (If the delay variation is out of the soft combinationrange during soft handover, only hard handover is allowed.)
If the Iub satellite transmission is disabled, the RNC denies the NodeB using satellitetransmission.
The following parameters are associated with Iub satellite transmission.
NOTE
The default parameters of the SSCOP/ALCAP/NBAP timers can meet the requirement of satellitetransmission. They need not be reconfigured.

4.1 Enabling Iub Satellite TransmissionThis describes how to enable Iub satellite transmission through the satellite equipmentinstallation and some MML commands.
Procedurel Enabling Iub satellite transmission
1. Configure transport layer data according to the terrestrial transmission status.2. Run the ADD NODEB command to add a NodeB. Set the value of IUB Trans Delay
[ms], and set Satellite Trans Ind to TRUE.
l Verifying the enabled feature
Make calls on satellite-based NodeBs.
----End
Example
// Enable Iub satellite transmissionADD NODEB: TnlBearerType=ATM_TRANS, TRANSDELAY=10, SATELLITEIND=TRUE;
4.2 Reconfiguring the Iub Satellite TransmissionParameters
This describes how to reconfigure the Iub satellite transmission parameters through the MMLcommands.
ContextNOTE
The Load Monitor (LDM) parameters and the Load Control (LDC) parameters can either be set by defaultor be manually reconfigured through the MML commands.
Procedure
Step 1 Run the MOD NODEB command to reconfigure IUB Trans Delay[ms] of a satellite-basedNodeB.
Step 2 Run the SET SATLDM command to reconfigure the Load Monitor (LDM) parameters.
Step 3 Run the SET SATLDCPERIOD command to reconfigure the Load Control (LDC) parameters.
----End
4.3 Disabling Iub Satellite TransmissionThis describes how to disable Iub satellite transmission through the MML commands.
