2 Overview of Satellite Transmission

Satellite transmission is a technology that provides satellite-based connections on the interfacebetween the network elements. For example, Iub satellite transmission is used to providesatellite-based connections on the Iub interface between the RNC and the NodeB. In general,the data between the RNC and the NodeB is transmitted on terrestrial transport networks throughcables, optical cables, or microwave. In some remote areas, coastal islands, deserts, anduninhabited areas where terrestrial transport networks are unavailable or difficult to deploy,satellite transmission is an ideal option for data transmission.

The advantages of satellite transmission are as follows:

l Wide coverage and insusceptible to terrainsl Good mobility for emergency communicationsl Easy link leasing or deployment, and easy to deployl Flexible bandwidth control

Satellite transmission, however, has disadvantages such as high costs of equipment and linkleasing, and high delay. Therefore, the satellite transmission is recommended only whenterrestrial transport is unavailable.

Huawei products support satellite transmission on the Iub interface and the Iu interface. In Iubsatellite transmission, the RNC and the NodeB are connected through satellite transmission links.In Iu satellite transmission, the RNC and the CN are connected through satellite transmissionlinks.

3 Technical Description

3.1 Satellite Transmission System

3.1.1 StructureSatellite transmission system consists of communications satellite and earth stations.

The geosynchronous satellite is usually adopted in satellite transmission. The satellite orbits ata distance of 36,000 km away from the earth and has an angular orbital velocity equal to theearth orbital velocity. A communications satellite consists of the control system,communications system (antennas and repeaters), telemeter system, power supply system, andtemperature control system.

An earth station consists of the antenna system, transceiver, channel terminal (modem),communication control system, and power supply system. The earth station can be a large-scaleor small-scale station:

l A large-scale earth station, such as a large-scale national or international communicationsstation, uses the large-aperture antenna to transmit high-speed data. The large-scale earthstation, however, has disadvantages. For example, a large-scale earth station costs morecompared with a small-scale one. And user data must be converged at the earth stationthrough terrestrial communication networks before being transferred through satellitecommunications.

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.

3.1.2 Network TopologyIub/Iu transmission links can be set up on the satellite network in the following three ways:

l Leasing existing large earth stations

If links provided by the existing earth stations are leased, it is not necessary to take intoaccount the network topology for satellite transmission or to manage satellite equipment.Service launch can be speeded up. The network topology, however, is restricted by thelocations of earth stations.

l Utilizing existing VSAT systemsNew sites are set up in the existing VSAT systems, which saves costs in routinemanagement and maintenance of the VSAT system. This method, however, is onlyapplicable to small-capacity networks due to limited bandwidth resources

l Setting up new VSAT systemsSetting up new VSAT systems brings clear network structures and easy capacity expansion.This method, however, increases investments.

In general, the NodeBs used in satellite transmission solution are usually deployed in remoteareas where no large earth stations nearby. In addition, the requirement of the remote base stationfor bandwidth is not very high. Consequently, the VSAT system becomes a suitable choice.

Figure 3-1 shows the VSAT system on the Iub interface.

Figure 3-1 VSAT system on the Iub interface

3.1.3 Bands for Satellite TransmissionTwo typical bands are available for satellite transmission. A proper band should be selected forsatellite transmission, depending on climatic conditions of the region and requirements forsatellite transport equipment.

Table 3-1 describes two typical bands for satellite transmission.

3.2 Iub Satellite TransmissionThis section describes the feature WRFD-050104 Satellite Transmission on Iub Interface.

3.2.1 StructureThe structure of Iub satellite transmission consists of the RNC, NodeB, earth station, andcommunications satellite.

Figure 3-2 shows the structure of Iub satellite transmission.

Figure 3-2 Structure of Iub satellite transmission



6

It is recommended that the star topology be applied in Iub satellite transmission to ensurereliability and reduce delay.

3.2.2 Impact on Protocol Stack Caused by Iub SatelliteTransmission

Figure 3-3 shows the protocol stack for the Iub interface.

Figure 3-3 Protocol stack for the Iub interface (based on ATM and IP)

Compared with terrestrial transmission, the value of the Round Trip Time (RTT) on the Iubinterface increases by 500 ms to 700 ms when the satellite transmission is used. Consequently,the RTT value on the Uu interface increases by 500 ms to 700 ms. To match with the increasedRTT, parameters on the Uu and Iub interfaces should be optimized.

For the NodeB using satellite transmission, the RNC adjusts the default values of the followingparameters:

l Load Monitor (LDM) parameter and Load Control (LDC) parameter

l Parameters related to the sliding window size and parameters related to the timer of theRLC at the data link layer

l Parameters of the FP transport synchronization timer

l Parameters of activation time of radio links

l Parameters of outer loop power control to protect voice and data quality from controlhysteresis



7

l Parameters for constraining the handover procedure (If the delay variation is out of the softcombination range during soft handover, only hard handover is allowed.)

If the Iub satellite transmission is disabled, the RNC will prohibit cell from setting up, and theNodeBs cannot use satellite transmission.

If flow control is required, run the ADD DLFLOWCTRLPARA command to set ITM toSATELLITE and set other parameters to correct values.

NOTE

The default parameters of the SSCOP/ALCAP/NBAP timers need not be reconfigured because they meetthe requirement of satellite transmission.

3.3 Iu Satellite TransmissionThis section describes/involves the feature "WRFD-050108 Satellite Transmission on IuInterface."

3.3.1 StructureIn Iu satellite transmission, the RNC and the CN are connected through satellite transmissionlinks.

Figure 3-4 shows the structure of Iu satellite transmission.

Figure 3-4 Structure of Iu satellite transmission.

The MGW which is directly connected with the RNC only forwards the data. The satellitetransport equipment between the RNC and the CN adds satellite delay for the transmissionbetween the RNC and the SGSN or between the RNC and the MSC.

3.3.2 Impact on Protocol Stack by Iu Satellite Transmission

Iu-CSFigure 3-5 shows the protocol stack for the Iu-CS interface.

Figure 3-5 Protocol stack for the Iu-CS interface (based on ATM and IP)

Generally, the default values of the timers of the control plane SAAL (SSCF/SSCOP/AAL5)/MTP3B range from hundreds of milliseconds to multiple seconds, and the increased RTT delaycaused by satellite transmission is about 500 ms to 700 ms. The default value of the timer mustbe increased because extra RTT delay is introduced. The timer length must be greater than theRTT delay caused by satellite transmission. Other timers defined in the protocol do not need tobe changed because their lengths are all greater than 1s.

The current value of the user plane IU-UP timer is 1s, which is greater than the RTT delay.

Iu-PSWhen the Iu satellite transmission is enabled, the increase of RTT delay affects the SAAL/MTP3B timers on the control plane. The adjustments of these timers are the same as those ofthe timers on the Iu-CS interface.

Iu-BC When the Iu satellite transmission is enabled, the timers are insensitive to the increase ofthe delay. Therefore, no adjustment is required.
