Abstract

The embodiment of the invention provides a calling method, a calling device and user equipment, and the method comprises the following steps: when the UE falls back from a first network to a second network to establish a voice call, measuring a signal of a pilot frequency adjacent cell based on a measurement configuration message; and if the call is abnormal, the UE records first cell information corresponding to a first target cell of the second network. And if the signal strength of the pilot frequency adjacent cell is greater than the signal strength of the first target cell, the UE records second cell information corresponding to the pilot frequency adjacent cell, and establishes a mapping relation table corresponding to the target frequency point and the second cell information. And the UE initiates a calling party or receives a called party in the source cell of the first network and / or in a preset time, judges whether the mapping relation table is recorded in the UE itself, and if the mapping relation table is recorded in the UE itself, determines a target cell to fall back according to a pilot frequency adjacent cell and / or a second target cell in the second cell information. The call service is ensured to be established in a cell with relatively high signal strength, and the call experience of a user is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a calling method, device, and user equipment. Background technique [0002] The fifth generation mobile network (5th generation mobile networks, 5G) is a new type of mobile communication technology. 3GPP has made it clear that the 5G standalone network (5G SA) will follow the voice architecture of the 4G mobile communication network and is still based on the IP multimedia subsystem (IP multimedia subsystem, IMS) provides voice services. The wireless access technology of the 4G mobile communication network is a long term evolution technology (long term evolution, LTE), and the voice call service carried on it is called VoLTE (Voice over LTE). The wireless access technology of the 5G mobile communication network is new radio (new radio, NR), and the voice call service carried on it is called VoNR (Voice over NR). After a user equipment (U...
