Scenarios and Challenges
SuperDSS enhances 2G/3G user loyalty during 2G/3G declines and guarantees legacy voice service experience, improves 4G/5G user throughput by 40%, enables unified configuration in the entire network and implements simplified O&M with intelligent 2G/3G and 4G shutdown to meet the requirement of 5G development along with network evolution.
Advantages and Highlights
During the evolution process from FDD to NR, at least one UMTS carrier or GSM TRX is required for legacy terminals voice service, as a result, LTE/NR DSS can’t be delivered in the whole bandwidth which is not an optimal way of spectrum utilization. If all the spectrum is used for LTE/NR DSS, legacy voice service experience can’t be guaranteed. According to service requirement, multiple configurations will occurred which causes a hybrid networking. Each time extra network planning is required along with the evolution to target network, which poses great challenge to network O&M.
SuperDSS is the industry’s first 2G/4G/5G or 3G/4G/5G dynamic sharing solution, among which 2G/3G resource allocation based on traffic requirement, when low traffic load, less bandwidth to be allocated even shutdown when there’s a 2nd carrier to cover traffic requirement, as a result, more spectrum resource can be used for 4G and 5G. It implements fast 5G track without degradation to legacy voice service experience, so as to maximize spectrum gain.
