Network subscription data acquisition method, device and system

The invention discloses a network subscription data acquisition method, device and system, and relates to the technical field of wireless communication. The method comprises the following steps: receiving a first identifier and a second identifier sent by a terminal; determining a subscription information query server corresponding to the first identifier; sending the second identifier to a subscription information query server, so that the subscription information query server queries subscription network information of the terminal according to the second identifier; and sending network signing data obtained based on the signing network information to the terminal. According to the invention, the terminal can obtain the network signing data under the condition that the terminal does not need to provide the signed network information for the network. 本公开公开了一种网络签约数据获取方法、装置和系统，涉及无线通信技术领域。该方法包括：接收终端发送的第一标识符和第二标识符；确定与第一标识符对应的签约信息查询服务器；将第二标识符发送至签约信息查询服务器，以使签约信息查询服务器根据第二标识符查询终端的签约网络信息；以及将基于签约网络信息得到的网络签约数据发送至终端。本公开
