Overview 5G Architecture Options from Deutsche Telekom

  1. 1. 5G architecture options – full set Joint RAN/SA meeting |June 14th 2016, Busan Deutsche Telekom AG RP-161266
  2. 2. Outline of architecture options in the light of 5G and “acceleration” discussion 2  Two radio technologies have to be considered in the 5G discussions  LTE (in its Rel-15 version) aka “eLTE” in sa2  Next generation Radio (“nr”)  plus radio level aggregation of both radio technologies in 2 variants  Two Core Network concepts have to be considered in the 5G discussions  EPC (with potential evolutions)  Next Generation Core („nGcn“)  This results in 12 options (next slides) 15.06.20165G architectureoptions | RAN/SA meeting, June 2016 RP-161266 S1_C S1_U NG2 (Controlplane) NG3 (Userplane)
  3. 3. 5G scenarios in 3GPP NR & NextGenCore (1/6) 15.06.2016 3 LTE EPC 1) Standalone LTE, EPC connected - legacy 2) Standalone NR, NGCN connected 5G architectureoptions | RAN/SA meeting, June 2016 RP-161266 NR NextGen Core
  4. 4. 5G scenarios in 3GPP NR & NextGenCore (2/6) 4 LTE NR EPC NextGen Core 3) Non-Standalone/”LTE assisted”, EPC connected 15.06.20165G architectureoptions | RAN/SA meeting, June 2016 RP-161266 LTE NR EPC NextGen Core 3a) Non-Standalone/”LTE assisted”, EPC connected „1a“
  5. 5. 5G scenarios in 3GPP NR & NextGenCore (3/6) 5 4a) Non-Standalone/”NR assisted”,NGCN connected LTE NR EPC NextGen Core 15.06.20165G architectureoptions | RAN/SA meeting, June 2016 RP-161266 „1a-like“ 4) Non-Standalone/”NR assisted”, NGCN connected LTE NR EPC NextGen Core
  6. 6. 5G scenarios in 3GPP NR & NextGenCore (4/6) 6 LTE 5) Standalone LTE Rel-15, NGCN connected 6) Standalone 5GNR, EPC connected NextGen Core EPC 15.06.20165G architectureoptions | RAN/SA meeting, June 2016 RP-161266 NR
  7. 7. 5G scenarios in 3GPP NR & NextGenCore (5/6) 7 LTE NR EPC NextGen Core 7) Non-Standalone/”LTE assisted”, NGCN connected 15.06.20165G architectureoptions | RAN/SA meeting, June 2016 RP-161266 LTE NR EPC NextGen Core 7a) Non-Standalone/”LTE assisted”, NGCN connected „1a-like“
  8. 8. 5G scenarios in 3GPP NR & NextGenCore (6/6) 8 8a) Non-Standalone/”NR assisted”, EPC connected LTE NR EPC NextGen Core 15.06.20165G architectureoptions | RAN/SA meeting, June 2016 RP-161266 „1a-like“ 8) Non-Standalone/”NR assisted”, EPC connected LTE NR EPC NextGen Core
  9. 9. Questions and conclusions 9  scenario 1) is legacy  11 options remain  Does 3GPP need to support all remaining 11 architecture options ?  Is there a phasing possible / desirable ?  How to ensure forward compatibility in order to avoid global fragmentation, especially considering roaming ? 15.06.20165G architectureoptions | RAN/SA meeting, June 2016 RP-161266
  10. 10. Status of RAN2 / RAN3 discussions per option (kindly provided by Hideaki-san) 1015.06.20165G architectureoptions | RAN/SA meeting, June 2016 RP-161266 --Scenario 1 RAN2 RAN3 YESYESScenario 2 YESYESScenario 3 / 3a YESYESScenario 4 / 4a YESNOScenario 5 NO ?NOScenario 6 YESYESScenario 7 / 7a NONOScenario 8 / 8a
