Question: What are the different types of SRVCC? And which are supported by QCOM IMS solution?
Answer:
only rSRVCC is NOT supported by QCOM IMS solution.

All other SRVCC are supported:
aSRVCC = SRVCC during alerting stage
bSRVCC = SRVCC before alerting stage
eSRVCC = enhanced SRVCC, which is a network feature for reducing audio delay from SRVCC
rSRVCC = SRVCC in the reverse direction CS call to VoLTE call
mid-call SRVCC = SRVCC which allows both active and held calls to be transferred from VoLTE calls toCS calls
