22.1053GPPRelease 17Services and service capabilitiesTS
This section describes the features that will be dependent on the mode of radio access.
In general different access networks provide different capabilities with different QoS.
– Multicall, as specified in 3GPP TS 22.135 , is supported only via UTRAN.
– Packet switched traffic using GPRS over GERAN will have a maximum rate in the order of 384kb/sec.
– Packet switched traffic using UTRAN will have a maximum rate in the order of 2Mb/sec.
– Packet switched traffic using HSDPA provides very high speed downlink packet access over the air interface supporting streaming, interactive and background packet data services etc. HSDPA will support packet data services in urban environments and indoor environments. However HSDPA service support is not be limited to these environments. HSDPA will be optimised at speeds typical of urban environments but shall apply at other speeds also. Full mobility will be supported, i.e., mobility should be supported for high-speed cases also, but optimisation should be for low-speed to medium-speed scenarios.
– ASCI teleservices, 3GPP TS 22.003  are only available in GERAN A/Gb mode of operation.
– SoLSA feature is only available in GERAN A/Gb mode of operation.
– The accuracy of the determination of location may differ between the various access technologies.
– At GERAN reception of CBS messages for a UE is not supported if it is connected in the CS domain or in the PS domain when data is currently transmitted.
– Transparent (T) mode of facsimile , as specified in 3GPP TS 22.003 , is only supported by GERAN A/Gb mode of operation.
– Non-transparent (NT) mode of facsimile, as specified in 3GPP TS 22.003 , is only supported by UTRAN.
– There are some differences at data rates and interworking scenarios between GERAN and UTRAN support of circuit bearer services . For further details see 3GPP TS 22.002 .
