Mobile application design introduces opportunities in inter-layer protocol optimization. Intelligent balancing between mobile application speed and mobile terminal power consumption are implemented using smart design and optimization in radio and network layer protocols.
Inter-Layer Optimization Enhances User Experiences
With the massive proliferation of mobile devices such as tablets, smartphones, and advanced e-readers, it is increasingly necessary for mobile device developers and network operators to dynamically adapt to mobile application Quality of Service requirements. This reduces network signaling and mobile terminal power consumption. Intelligent inter-layer optimization and traffic pattern prediction enhance user experiences.
Optimizing Mobile Applications is Critical to Carrier Aggregation
Carrier aggregation technologies increase data rates and capacity. In general, power consumption increases as more carriers are activated and synchronized. New technologies can reduce this power consumption by timely activating and synchronizing secondary carriers based on application Quality of Service needs.
Quality of Service Introduce Implementation Opportunities
Most mobile devices can access multiple communication networks such as: 3G, 4G, 5G, WiFi, WiMAX, and wired networks. Performance of applications running on mobile devices can be increased by selecting networks that match the applications Quality of Service requirements. New intelligent adaptive Quality of Service algorithms select and aggregate radio access from multiple communication networks as a mobile device travels to maintain a high Quality of Service.
Predicting Application Needs Enhances Quality of Service
New technologies overcome the bursty nature of mobile application traffic patterns to provide a higher Quality of Service to mobile applications. Predicting future traffic flow based on user actions and behavior improves the performance of the applications Quality of Service.
CU-DC Architecture
The 5G functional split feature supports that a base station is divided into a central unit (CU) and distributed unit (DU). Upper layer functions, such as SDAP and PDCP, reside at the central unit and lower layer functions, such as RLC/MAC/PHY, reside at the distributed unit. A central unit controls multiple distributed units that covers wide area. The CU-DU based functional split architecture increases scalability and control efficiency of an access network.
