[...] Cellular base stations (BSs) are equipped with backup batteries to obtain the uninterruptible power supply (UPS) and maintain the power supply reliability. While maintaining the reliability, the backup batteries of 5G BSs have some spare capacity over time due to the traffic-sensitive characteristic of 5G BS electricity load.
In practice, the battery groups (either traditional lead-acid batteries or emerging lithium ones) are deployed as the backup power supply of BSs. In our scenario, one battery group could be shared by multiple BSs nearby to exploit the statistical multiplexing gain, and the multiple BSs sharing the same battery group form a virtual cell (VC).
Therefore, BS power backup is in great need to keep the reliability of future mobile networks, especially for the macro BSs with large areas of network coverage and small ones serving mission-critical mobile and edge services (e.g., connected and automated vehicles ).
In this chapter, we proposed an optimal backup power allocation framework for BSs, ShiftGuard, to help the mobile network operators reduce their backup power cost in shifting to the 5G network and beyond.
