Network Operator’s Business Community aims to utilize their installed equipment as much as possible for efficiency reasons because each additional technology layer constitutes an important portion of total capex expenditures. A generic approach is to configure network parameters so that UEs that support both new and older radio access technology layers would camp on and use services from latest technology with 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 for areas where new technology is overlayed on top.

RRC connection usage per UE multi-mode/multi-RAT capability related measurement will be helpful for operators to identify how efficient they utilize their deployed radio access technology layers and perform corrective actions when needed.
