Abstract

The invention relates to a calling method and device, and the method comprises the steps: initiating a call based on a CSFB (Circuit Switched Fallback) service in a first network; and initiating a call based on a non-CSFB service in the second network in response to the fact that the cell where the terminal is located in the second network executing the call does not support the CSFB service. According to the invention, the terminal can be compatible with the cell which does not support the CSFB service, thereby avoiding the call failure caused by the cell which does not support the CSFB service, and improving the call success rate.

Description

Technical field [0001] The present disclosure relates to the field of communication technology, in particular, to a calling method and apparatus, electronic devices and computer-readable storage media. Background [0002] Currently, networks such as LTE (Long Term Evolution) do not include the CS (CircuitSwitched, circuit-switched) domain, and voice calls cannot be made directly. In general, voice calls in LTE networks can be implemented using VOLTE (Voice overLong-Term Evolution) or CSFB (Circuit Switched Fallback) technologies. [0003] Among them, CSFB technology is suitable for environments where LTE and 2G / 3G wireless networks overlap coverage. Terminals connected to the LTE network can fall back to the CS domain of the 2G / 3G network to make voice calls. [0004] However, if the cell where the terminal is located in the 2G / 3G network does not support CSFB service, the call will fail. Contents of the Invention [0005] In view of this, embodiments of the present disclosure ...
