SRVCC HANDOVER DECISION BASED ON STATISTICAL DATA ON TERMINAL BEHAVIOR

摘要

A technique for optimizing, based on information from an analytics engine, a decision concerning an SRVCC handover of a UE is disclosed. In a first method aspect, the method is performed in an IMS core and comprises the steps of inquiring, from the analytics engine, a recommendation on whether the PS domain or the CS domain is to be the access domain for an originating side for the UE, receiving the recommendation comprising a probability per UE that an SRVCC handover will occur after initiation of a voice call in VoLTE, and selecting, based on the probability, one of the PS domain and CS domain as the access domain for the originating side for the UE. In a second method aspect, the analytics engine has stored, per UE, a probability that an SRVCC handover will occur after initiation of a UE voice call in VoLTE. The engine transmits the recommendation comprising the probability per UE.
