AI Technical Summary
Technical Problem
In 5G network roaming scenarios, if the terminal device does not support the New Radio voice bearer mode, it cannot quickly fall back to the home operator's 4G network to carry out voice services, resulting in voice service failure.
Method used
By working together with access devices and mobility management network elements, a suitable target PLMN is determined based on the mapping relationship between the pre-configured PLMN identifier and access information, enabling rapid fallback of terminal devices.
Benefits of technology
When a terminal device initiates a voice request, it can quickly fall back to the appropriate home operator's 4G network to complete the voice service, thus solving the problem of voice service interruption.

Abstract
本申请实施例提供网络接入方法、装置及计算机可读存储介质，涉及通信技术领域，可以解决漫游场景中终端设备在建立语音业务时无法迅速回落到适合的网络的问题。该方法包括：接入设备接收来自移动管理网元的第一公共陆地移动网络PLMN的标识；接入设备根据第一PLMN的标识、以及预配置的PLMN的标识与接入信息的映射关系，确定与第一PLMN的标识对应的第一接入信息；在接入设备接收来自终端设备的第一消息之后，接入设备向终端设备发送第一接入信息；第一接入信息用于终端设备接入第二PLMN，其中，第一消息用于请求建立语音业务，第二PLMN的网络制式低于终端设备当前接入的PLMN的网络制式。
