Abstract

The present invention discloses a call switching method, vehicle terminal, and core network, relates to the field of vehicle networking technology, and is used for solving technical problem in the prior art that when a user is making phone calls with a mobile terminal while entering a vehicle, the user cannot perform seamless switch-over of voice calls between a mobile terminal and a vehicle terminal. The method includes: when the vehicle terminal detects that the mobile terminal is in a predetermined range, the vehicle terminal establishes a connection with the mobile terminal through a short-distance communication manner; the vehicle terminal detects whether the mobile terminal is in a call state; wherein the vehicle terminal is associated with the mobile terminal in the core network; ifdetection result is yes, the vehicle terminal sends a first call switch-over request carrying a first call switch-over identifier to the core network; the core network receives the first call switch-over request sent by the vehicle terminal, and switches calls of the mobile terminal to the vehicle terminal through the first call switch-over identifier. The method is used for call switching of thevehicle terminal.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of the Internet of Vehicles, and in particular to a call switching method, a vehicle terminal and a core network. Background technique [0002] With the continuous application and popularization of vehicle-mounted terminal voice call services, users' demand for vehicle-mounted terminal voice call services continues to increase. At present, when the user is using a mobile terminal to make a call and enters the vehicle, if the vehicle-mounted terminal is started at this time, the user often hopes that the vehicle-mounted terminal can automatically continue the ongoing mobile terminal call, so as to meet the user's call needs and facilitate the user's execution. driving action. [0003] However, in actual situations, when the above situation occurs, it is currently impossible to switch calls between the mobile terminal and the vehicle-mounted terminal, which makes it very inconvenient for...
