Automation and Integration of SSI Test Cases for Abis and A-Interface in GSM Using Robot Framework

Mobile wireless communication has undergone vast advancements in the last few decades due to the growth of subscribers. There is a rapid growth in the number of features required by the users and the companies need to deliver products in a very short time. As the demands of users increasing the time required to release a product into the market also increases. Global System for Mobile Communication (GSM) is a second-generation mobile cellular system in cellular networks. Exchange Terminal for Packet Transport (ETP) is a plug-in-unit placed between Base Transceiver System (BTS)—Base Station Controller (BSC) and BSC—Media Gateway (MGW) in GSM to improve the bandwidth and is an important component to handle GSM and GPRS (General Packet Radio Services) calls. It is used in BSC to support the packet-based transmission of signaling and payload between the BTS and the BSC for Abis and A over IP (AoIP) interfaces. In this paper, to carry out automation testing, an automation tool called Robot Framework is used that helps to test ETP functionality. This framework allows execution of Sub-System Integration (SSI) Test cases for Continuous Integration and executes the test cases developed for ETP feature at one stretch without manual intervention.
