| |
7d12b515375832bdb38ea519e14adcb0 | 23.700-56 | 6.1.0 High-level solution Principles
| This solution addresses Key Issue #1: DC establishment in alerting phase for early media.
The solution reuses Rel-19 TS 23.228 [2] with the addition that
- Based on the UE request (via a specific root URL) , the DSCF sends to the UE(s) an application list related with the alerting phase- The calling party receive BD... |
7d12b515375832bdb38ea519e14adcb0 | 23.700-56 | 6.1.1 Description
| This solution provides a procedure on how to establish a P2A ADC in alerting phase.
Editor's note: Current version of the solution supports P2A ADC establishment in alerting phase. it is FFS whether it can support other forms of ADC, i.e. P2A2P and P2P.
|
7d12b515375832bdb38ea519e14adcb0 | 23.700-56 | 6.1.2 Procedure
| The pre-condition of ADC establishment in alerting phase is the capability negotiation during the IMS registration phase on whether the UE supports the DC in alerting phase.
Based on the IMS DC capability negotiation defined in clause AC.7.0 of TS 23.228 [2], when the UE supporting DC in alerting phase and the UE is a... |
7d12b515375832bdb38ea519e14adcb0 | 23.700-56 | 6.1.3 Impacts on Services, Entities and Interfaces
| The solution has the following impacts:
UE:
- supporting retrieving DC application list and DC application for alerting phase; this includes providing a specific URL to get from DCSF the application list for alerting phase,
- supporting ADC establishment in alerting phase.
IMS AS:
- supporting negotiation of ADC i... |
