Radio Resource Management - Connection Mobility Control eNodeB Source Handover Strategies

Radio Resource Management (RRM) is an E-UTRAN Node B (eNodeB) application level function that ensures the efficient use of available radio resources. RRM manages the assignment, re-assignment and release of radio resources taking into account single and multi-cell aspects. Connection Mobility Control (CMC) is a sub-function of RRM. It is required in the idle as well as connected mode. In idle mode there will be cell selection and reselection. The connected mode will involve Handover procedures triggered on the basis of the outcome of CMC Algorithms. This paper primarily focuses on the connected mode of User Equipment (UE) at the Source eNodeB. We discuss a strategy for CMC, including a determination of Handover and the criteria for Target cell determination for Handover.
