Based on an MNO project in Africa that IPLOOK is actually delivering, we have summarized some experiences and steps on how a UE can successfully use VoLTE services with the help of GSMA, which we share with you for free as follows:
Step 1: A mobile device power-on
Step:2: Scan all supported frequency band
Step 3: Try to register on scanned MNO networks
Step 4: Try to attach with default bear QCI=9 for Internet service
Step 5: Try to attach with dedicate bear QCI=1 for VoLTE service
As a crucial role in this process, a mobile network operator (MNO) is a telecoms entity that controls all the elements including radio spectrum allocation, wireless network infrastructure and other necessary components, providing wireless voice and data services to mobile phone subscribers.
A new MNO needs to become a GSMA member before launch.The application documents include IR.21, IR.85..etc. The MNO must apply and pass GSMA testing for certificate of VoLTE capability. The baseline document is GSMA IR. 25.
PS: GSMA will update membership list globally.
IPLOOK can provide fully virtualized MNO solution for operators to simplify the network structure and reduce the O&M costs, helping TIER 1, medium and small-sized operators to achieve network modernization.
