After the introduction of 5G networks, legacy 2G/3G/4G networks will exist for a long time. When operators deploy new networks, they have to face many operation pain points of the 5G era caused by the long-term multi-network coexistence and handover.
- Multi-network correlation, impacting the rapid commercialization of 5G new services: Massive services need to apply to 2G/3G/4G/5G/Fixed networks, and service consistency is required for interoperation. To rapidly develop 5G new services, it requires legacy networks also being equipped with fast collaborative deployment capabilities.
