5G Service Indicator
GSMA progress on the 5G Service Indicator is captured in an LS RP-193053
RAN outlined the tasks to RAN2 to undertake the corresponding specification work
• Introduce signalling to enable a UE camped on an E-UTRA cell to be informed, with frequency band
granularity, of the NR frequency bands available for configuration of EN-DC operation
• For Idle (or Inactive), specify that the presence of the upperLayerIndication is only provided to upper layers
if the UE supports EN-DC operation for one or more of the indicated frequency bands.
• For Connected, specify that the presence or absence of the upperLayerIndication is provided to upper
layers depending on whether or not the UE is configured by RRC for EN-DC operation.
TSG RAN has decided that further 3GPP work related to the display of any user
interface indication, such as hysteresis to avoid toggling between displaying 4G and 5G
icon as mentioned in the GSMA LS, is not needed

TSDSI RIT aspects
RAN#86 provided information to TSDSI on aspects of compatibility
between 3GPP NR RAT and TSDSI RAT
• It is not possible for 3GPP to retroactively ensure compatibility with modifications which were
done outside of 3GPP. 3GPP have already made extensions to its RRC specifications that conflict
with modifications done by TSDSI.
• Great care has been taken to maximize efficiency of the RRC signalling. Any potential blanket
allocation of bits for the purpose of modifications done outside of 3GPP in the future (e.g. in
TSDSI) would severely compromise the efficiency of 3GPP’s RRC, and hence 3GPP will not do any
such blanket allocations.
• 3GPP RAN can only ensure forward- and backwards-compatibility for specifications maintained
inside 3GPP. 3GPP invites TSDSI to propose their modifications in 3GPP using its normal
processes
