Embodiment Construction

[0019] As 4G (Long Term Evolution (LTE)) enters the large-scale commercial stage, the fifth-generation mobile communication (5G) for 2020 and the future has become a global research and development hotspot. There are many different voice solutions in 5G, which are related to different networking modes. Currently, the 3rd Generation Partnership Project (3GPP) defines two schemes for 5G new air interface (New Radio, NR, also known as new wireless) networking, which are independent networking (Standalone, SA) and Non-standalone networking (Non-Standalone, NSA). For the 5G non-independent networking mode, since the control plane is anchored on the 4G network, it is a natural choice to use the voice service (Voice over LTE, VoLTE) solution for voice services; for the 5G independent networking mode, 3GPP proposes a new wireless voice (Voice Over New Radio, VoNR) and EPS fallback (EPS Fallback) two schemes. The VoNR solution refers to the provision of voice services based on the IP...

Abstract

The embodiment of the invention discloses a method and device for initiating cell reselection, a terminal and a storage medium, and the method comprises the steps that UE determines the voice capability of the UE and a voice scheme supported by a current resident cell; and the UE initiates cell reselection according to the voice capability of the UE and the voice scheme supported by the current resident cell.

Description

technical field [0001] Embodiments of the present invention relate to, but are not limited to, electronic technologies, and in particular, relate to a method, device, terminal, and storage medium for initiating cell reselection. Background technique [0002] In the existing fourth generation (4 th Generation, 4G) network has the fifth generation (5 th Generation, 5G) network, the user equipment (UE) used by users will also be mixed, some UEs will support 5G networks, some UEs only support 4G networks, and some UEs may support both 4G and 5G. In the era of 5G arrival, for some legacy UEs, only 4G voice solutions (Voice Over New Radio (VoNR) and Evolved Packet System (EPS) fallback (EPS Fallback)) are supported, so when When it initiates a voice service through a 5G network, if the network can provide voice services, such as the network only supports EPS fallback, the UE will be switched or redirected to 4G to complete the voice service; if the network only supports VONR, ...
