本文的目的是展示使用通用软件无线电外设（软件定义无线电 (SDR) 的多用途主板）和个人计算机 (PC) 实现 GSM 基础收发器系统 (BTS) 的经验。 OpenBTS 项目提供了一个为 GNU Radio 环境创建的软件套件，能够模仿 GSM BTS 的行为。为了允许GSM用户拨打电话和发送短信，需要在SDR主板上进行一些硬件修改，设置会话发起协议(SIP)服务器，配置该服务器以提供移动设备和VoIP回程之间的连接。在本文中，我们将说明创建小型、廉价且自主的 GSM BTS 所需的软件和硬件以及必要的步骤。
The objective of this paper is to show the implementation experience of a GSM Base Transceiver System (BTS) by using Universal Software Radio Peripheral, which is a multipurpose motherboard for Software Defined Radio (SDR), and a Personal Computer (PC). The OpenBTS project provides a software suite, created for the GNU Radio environment, and able to mimic the behavior of a GSM BTS. In order to allow GSM users to make calls and send text messages, it is necessary to operate some hardware modifications on the SDR motherboard, to set up a Session Initiation Protocol (SIP) server, to configure the server for providing connectivity between the mobile devices and the VoIP backhaul. In this paper, we will illustrate the needed software and hardware, and the steps necessary to create a small, cheap and autonomous GSM BTS.
