Mobility management entity (MME) system and method to disable voice over LTE (VoLTE) service of a long term evolution (LTE) base station

摘要

A Mobility Management Entity (MME) system and method to disable Voice over LTE (VoLTE) service of a Long Term Evolution (LTE) base station (BS) are provided. The MME system in one example includes a data communication interface configured to receive VoLTE performance metrics and transmit and receive signaling messages over a communication network and a processing system configured to process VoLTE performance metrics obtained through the data communication interface to determine if VoLTE service on the LTE BS should be disabled, and if VoLTE should be disabled and if a create bearer request obtained through the data communication interface has a Quality-of-Service Class Identifier (QCI) value indicating a VoLTE session for a UE, transfer a reject message for delivery to the UE instructing the UE to use a different BS for voice service.
