Abstract
Devices and methods for handling phone calls. One device is a user equipment (UE) configured to establish a connection with a first evolved Node B (eNB). A method includes transmitting an invite signal to a further UE for a Voice over LTE (VoLTE) call, receiving an accept signal from the further UE, receiving a fail signal from the first eNB that a dedicated bearer is unavailable, generating a trigger signal in response to receiving the fail signal and transmitting the trigger signal to the first eNB. Another device is a base station (e.g., eNB) that receives a VoLTE call request from a UE, determines whether the eNB has sufficient resources to provide a dedicated bearer. When it is determined the eNB has insufficient resources, the eNB determines whether a further eNB has sufficient resources to provide the dedicated bearer, and determines whether the UE can connect to the further eNB.
