Zusammenfassung:	A call service implementation method and apparatus, and an electronic device and a readable medium. The method comprises: determining whether a first state of a terminal in an eMSC is consistent with a second state of the terminal in an IMS; if the first state of the terminal in the eMSC is inconsistent with the second state of the terminal in the IMS, sending a registration request to the IMS, so that the terminal completes an initial call service, wherein the eMSC does not subscribe to registration state information in the IMS.
