Enable PS Redirection from 3G to 4G in Huawei Network

In this sharing, I would like to share you about how to Enable PS Redirection from 3G to 4G in Huawei Network. In The beginning of new 4G network in my project this kind activity would be done in Optimization activity. Here are some parameter in 3G that need to be created in CR (Change Request) regarding enabling PS Redirection from 3G to 4G LTE in Huawei Network.
