The embodiment of the invention provides a VOLTE service processing method, a device, an electronic device and a storage medium. The method comprises the following steps: the receiving end receives the VOLTE service registration message sent by the sending end. The VOLTE service registration message is used for requesting to register the VOLTE service in the cell accessed by the UE; and the methodcomprises the identification of the cell accessed by the UE. The VOLTE service registration message is used for requesting to register the VOLTE service in the cell accessed by the UE. If the receiving end judges that the obtained cell identifier matches with the pre-stored cell identifier data forbidding registration of VOLTE service, the receiving end returns a failure response to the sending end to forbid the UE from registering VOLTE service in the accessed cell. The receiving end determines that the received cell identifier matches the pre-stored cell identifier data forbidding registration of VOLTE service. The method pre-stores identification data of a cell prohibited from registering VOLTE service through a receiving end, After receiving the VOLTE service registration message, ifthe identification of the cell accessed by the UE matches the identification data of the cell prohibited from registering the VOLTE service stored in advance, the UE is prohibited from registering theVOLTE service in the cell currently accessed, thereby improving the processing accuracy of the prohibited VOLTE service to the cell level without affecting the user perception.
