Volte Activation : SRVCC issue -- Vendor E ///

[karimos]

Hi experts

We did a trial for Volte activation on a cluster. we noticed that SRVCC to Utran dosent work.

After change the parameter : srvccCapability from PS_AND_CS_SUPPORTED to CS_ONLY_SUPPORTED, problem was resolved.


Can anyone support to check and expain why SRVCC works with srvccCapability=CS_ONLY_SUPPORTED and not with srvccCapability=PS_AND_CS_SUPPORTED ?.

Is there a related parameter or feature to double-check for RAN side or other setting from Core Side to check so that SRVCC become working with
rvccCapability=PS_AND_CS_SUPPORTED ?

Ericssson vendor.

Thanks in advance

Hi,

PS_AND_CS_SUPPORTED is not supported from your core network that's why you were getting failure . Nothing further from RAN can be done . Get in touch with your IMS team
