Section: A.35 Monitoring of RRC connection usage per UE multi-RAT capability
Content: An objective for an operator is to utilize installed network functions as much as possible for efficiency reasons because each additional technology layer constitutes an important portion of total capex expenditures. A generic followed approach is to configure network parameters so that UEs that support both new and old radio access technology layers would camp on and use services from new radio access technology for better cost per bit characteristics. Therefore, it is of utmost importance for an operator to know if new technology capable UEs are served by old radio access technology in geographical areas where new technology is overlayed on top. RRC connection usage per UE multi-RAT capability related measurement is helpful for operators to identify how efficient they utilize their deployed radio access technology layers and perform corrective actions when needed.
