Title: [FS_ULBC] Updates of the permanent document based on 3GPP TR 23.700-19
Agenda item: 7.8
Agenda item description: FS_ULBC (Study on Ultra Low Bitrate Speech Codec)
Doc type: pCR
For action: Agreement
Abstract: SA2 has reached conclusions on Key Issue #1 regarding the support of IMS voice call over NB-IoT via GEO satellite connecting to EPC, as documented in TR 23.700-19. It has been agreed that voice packets shall be transported over the NB-IoT (GEO) user plane (UP) using DRB and S1-U, and that a single PDN connection shall be used for both IMS signaling and IMS voice. Furthermore, the TR specifies that the voice data transport mechanism of IP packets is mandatory (UP/IP, recommended with RoHC), whereas the mechanism involving the removal and restoration of parts of RTP/UDP/IP headers is optional (UP/non-IP). This contribution updates the FS_ULBC Permanent Document to align the transport path assumptions and solution details with these agreements.
