Research in CRRM has many directions, e.g. policy translation and configuration, RAT selection, admission control, congestion control, horizontal handover, and packet scheduling. RAT selection algorithm is a key research area of CRRM at present. A suitable RAT selection algorithm can manage radio resources among multiple RATs more efficiently, enhance system performance, and provide better QoS to users. The RAT selection algorithm contains two parts: initial RAT selection and vertical handover (VHO). The former is used to allocate new calls to a suitable RAT and the latter is about transferring an ongoing call from its current serving RAT to a more suitable RAT.
