The present document studies and identifies the changes to the LI architecture, function and protocols for inbound roamers in the VPLMN when S8HR is employed which is equivalent to the LI service level for Local Breakout (LBO) in the VPLMN for VoLTE services. Covered by the present document includes:
  • Potential enhancements to the LI service architecture to accommodate the S8HR roaming architecture in the VPLMN to meet all the current LI regulatory requirements applicable to voice and other IMS service roaming are considered and compared.
  • Considerations on maximizing re-use of existing 3GPP defined capabilities such as PCC is considered.
  • Exploration of the changes that may be needed to TS 33.107 and TS 33.108. Finally, the present document provides recommendations for proceeding with implementing the selected approach.
This study item takes into account GSMA related activities.
