RAN5 – Mobile Terminal Conformance Testing

Image

Within the 3GPP Technical Specification Group Radio Access Network (TSG RAN), the 3GPP TSG RAN WG5 (RAN5) is the Conformance Testing Group for User Equipment (UE).

The main objective of RAN5 is the development of UE conformance test specifications at the Radio Interface dealing with GERAN, UTRA, Evolved UTRA(E-UTRA), 5G NR and beyond based on 3GPP core specifications.

The test specifications are mainly based on the requirements defined by other groups such as RAN WG4 for the radio test cases and RAN WG2 and CT WG1 for the protocol test cases. RAN WG5 is organised in two subgroups, RF subgroup and Signalling (SIG) subgroup.

RAN WG5 is currently responsible for:

  • RF conformance tests in coordination with the other relevant RAN working groups.
  • RRM conformance tests in coordination with the other relevant RAN working groups.
  • Positioning conformance tests in coordination with the other relevant RAN working groups.
  • GERAN, UTRA, E-UTRA, 5G NR and beyond; IMS, NAS, EPC, 5GC and Positioning protocol tests in coordination with the other relevant RAN, CT and SA working groups.
  • Mission Critical Services client (UE) and server (UE or network) protocol tests in coordination with the other relevant RAN, CT and SA working groups.
  • Tests to cover Inter RAT procedures (GERAN, UTRA, E-UTRA and 5G NR).
  • The formal description (prose) of protocol test cases for UTRA, E-UTRA, 5G NR and beyond; Inter RAT, IMS, NAS, EPC, 5GC, Positioning and Mission Critical Services using TTCN in coordination with MCC TF160.
