Abstract
The disclosure relates to a method for Internet Protocol based Multimedia Subsystem (IMS) registration and device, a communication device, and a storage medium. The method for IMS registration includes determining whether a network side supports an IMS service; acquiring, based on an IMS Access Point Name (APN), an address for the IMS registration when the network side supports the IMS service; performing the IMS registration based on the acquired address for the IMS registration; and initiating an IMS re-registration when the IMS registration fails.
