Terminal access control method, device and system, terminal and electronic equipment

The invention discloses a terminal access control method, device and system, a terminal and electronic equipment, and relates to the technical field of wireless communication. The method comprises the following steps: receiving a registration request for acquiring network subscription data sent by a terminal; determining an abnormal reason that the terminal cannot acquire the network subscription data; sending the abnormal reason to the terminal, so that the terminal determines whether to re-initiate the registration request according to the abnormal reason. According to the invention, the problem of resource waste caused by frequent registration attempt of the terminal can be reduced, and the success rate of acquiring subscription data through a network by the terminal is improved. 本公开公开了一种终端接入控制方法、装置、系统、终端和电子设备，涉及无线通信技术领域。该方法包括：接收终端发送的获取网络签约数据的注册请求；确定终端无法获取网络签约数据的异常原因；以及将异常原因发送至终端，以使终端根据异常原因确定是否重新发起注册请求。本公开能够减少因终端频繁尝试注册导致资源浪费的问题，提高了终端通过网络获取签约数据的成功率。
