A.4 SRVCC from GERAN / UTRAN to E-UTRAN / UTRAN (HSPA)
23.2163GPPRelease 16Single Radio Voice Call Continuity (SRVCC)Stage 2TS
GERAN/UTRAN may determine the NCL, as well as the need to signal a CS to PS SRVCC indication, as follows:
– If the "CS to PS SRVCC operation possible" indication is set to "true" (i.e. both the network and UE are CS to PS SRVCC capable, and a valid IMS registration via PS still exists), and the UE has indicated in Radio Access Capabilities support for CS to PS SRVCC to this RAT, then VoIP-capable cells may be included as candidate target cells in the NCL, regardless of the presence of an established TS 11 bearer for this UE. Moreover:
– if there is an established TS 11 bearer for this UE and the selected target cell is VoIP-incapable, then GERAN/UTRAN does not indicate that the handover is for CS to PS in the Handover Required message;
– if there is an established TS 11 bearer for this UE and the selected target cell is VoIP-capable, then GERAN/UTRAN indicates that the handover is for CS to PS in the Handover Required message;
– if there is no established TS 11 bearer for this UE, then GERAN/UTRAN does not indicate that the handover is for CS to PS in the Handover Required message;
– If the "CS to PS SRVCC operation possible" indication is not set (i.e. either the network or UE is not CS to PS SRVCC capable, and a valid IMS registration via PS still exists), or the UE has not indicated in Radio Access Capabilities support for CS to PS SRVCC to this RAT, then GERAN/UTRAN does not indicate that the handover for CS to PS in the Handover Required message. Moreover:
– if there is an established TS 11 bearer for this UE, then VoIP-capable cells are not be included in the NCL;
– if there is no established TS 11 bearer for this UE, then VoIP-capable cells may be included in the NCL.
