Major challenges
Description
Handover Transparent
Ensure smooth and seamless transitions when moving from one network to another to avoid service interruptions and QoE disruptions
Handover decisions
Make handover decisions based on factors such as signal quality, network load, and user preferences while minimizing QoE impacts
Internetwork handover
Effectively manage handovers between different technologies and network types, such as switching from WiFi to cellular networks, while maintaining optimal QoE
Latency management
Reduce latency during handover transitions to avoid any user-perceivable delay
Energy optimization
Perform handovers in a way that minimizes the power consumption of mobile devices while maintaining satisfactory QoE
