Hi Experts.

Anyone with idea how to implement Fast Return for SRVCC calls in UTRAN based on redirections only.

Vendor: Huawei

RWR from 3G to 4G is expected to be ON for all cases.
After SRVCC is done and the UE finishes the call, it will be in Idle Mode. Once in Idle Mode it will automatically RWR to LTE

Have you deployed in your Network for SRVCC calls? In my observation, RRC connection release is not received by test UEs neither the related counter is pegging. RRC connection release for CS fallback and normal 3g to 3g calls is seen in L3.

Yes SRVCC is deployed in our network and UE reselects back to 4G easily. Thanks!

Anyone else who can share how it’s deployed in Huawei?
