Abstract

The embodiment of the invention discloses a domain selection method and device for a called service and a storage medium, and belongs to the technical field of communication. The method comprises thefollowing steps: when a terminating service is processed, determining a domain where a called user is located; and selecting a call processing flow corresponding to the domain to process the terminating service, so that the terminating service directly completes the continuing and paging of the called user in the domain. By adopting the embodiment of the invention, if the called user resides in the CS domain, the terminating service can be directly processed in the CS domain, and the call does not need to be anchored to the IMS domain firstly, so that the signaling circuitous problem caused byanchoring the call to the IMS domain firstly and then returning the call to the CS domain when the called user is in the CS domain is avoided.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of communication, and in particular to a domain selection method, device and storage medium for a called service. Background technique [0002] VoLTE is Voice Over LTE, which is a voice service based on IMS (IP Multimedia Subsystem, multimedia subsystem). After VoLTE is deployed, in order to realize the called voice service of VoLTE users, a domain selection scheme needs to be deployed. [0003] The domain selection scheme in the prior art is the anchor domain selection scheme. This scheme anchors T-CSI (Terminating CAMEL Subscription Information, called user subscription information) for VoLTE user subscription, and the user is in the CS domain (Circuit Switching Domain, circuit switching domain ) triggered called services are anchored to the IMS (IP Multimedia Subsystem, multimedia subsystem) domain through the anchor SCP (Service Control Points, service control point), and all s...
