Study on service aspects for supporting the eMMTel Service
The present document studies the following aspects:
1) service aspects for supporting the eMMTel service based on requirements from stage 1, e.g. eMMTel specified in 3GPP TS 22.261 [2] and SA WG1 Rel-18 eMMTEL WID;
2) the service enabler layer capabilities exposure based on architecture and procedures specified in Annex AC.2 of 3GPP TS 23.228 [3] and SA WG2 Rel-18 NG_RTC WID; and
3) the necessary application layer architecture and procedures for enabling MMTel service enhanced with Data Channel usage in IMS network.
