The present document captures the results of the study and evaluation of possible solutions for architectural enhancements to support Group Communication System Enablers for LTE (GCSE_LTE). The Stage 1 requirements for GCSE_LTE are defined in TS 22.468. Specifically, GCSE_LTE covers the following aspects:
  • Group Communication (GC) among entitled group members via E-UTRAN;
  • Group Communication (GC) among entitled group members using E-UTRAN and members of the same group using ProSe communication paths via a ProSe UE-to-Network Relay;
  • The relationship between ProSe and GCSE for GCs.
The functional descriptions of "ProSe communication paths via ProSe UE-to-Network Relay" and "ProSe GCs" have been defined in TR 23.703.
