Limitations

Following are the known limitations for Packet Data Unit SessionsEstablishment from 4G-Only and Option 3x Capable Devices feature:

  • For PresenceAreaReporting (PRA) feature, only the PRA-ID will be sent in ‘Presence reporting area action’ IE on S5 interface, user location info won’t be sent.

  • For PresenceAreaReporting (PRA) feature, only the PRA-ID will be sent in ‘repPraInfos’’ IE on N7 interface, user location info won’t be sent.

  • For PRA feature, PRA Set is not supported, due to which “Additional PRA Information” sent on S5/N7 interfaces is also not supported.

  • Maximum of 4 PraIds will be processed in a single PCF update message, if any PCF update has more than 4 PraIds then the other PraIds are ignored.

  • PRA is applied only based on RAT from which device is connecting, not based on device type. So it is applied to both 4G and 5G devices, when connected from LTE

  • SecondaryRatDataUsage Report supports only Option3 and Option3x (NR secondary RAT) UEs on S5 interface.

  • SecondaryRatDataUsage Report isn’t supported on N2 interface for E-UTRAN Secondary RAT.

  • PresenceAreaReporting (PRA) feature is supported only towards PCF and not towards CHF.

  • Ultralow latency QCIs aren’t supported.
