Characteristic Comparison Method to Identify Device Residential Gateway

Internet Service Provider (ISP) needs to get more details information about Customer Premises Equipment (CPE), especially the Residential Gateway (RG), before advice customer to self-troubleshooting. Moreover, the CPE information is not up to date in ISP inventory system due to firmware upgrading or CPE replacement without ISP's consent. If the customer failed to notify details of RG, then ISP has two options either send the truck roll or use self-service or remotely application. In this paper, we proposed a design and a develop characteristic comparison method implemented in android platform. We use five meta-data; string, object, media access control (MAC) address, Organizationally Unique Identifier (OUI) and URL, to describe the characteristic of the RG. The identification of 19,519 units of Device under Test (DUT) shows that 11 of 12 DUT have high rate accuracy more than 95%. Only 1.35% of DUT failed in identified. Therefore, the characteristic comparison will be used to identify the RG pre-owned by the customer via Wi-Fi android devices and will heel ISPs contact center to guide the customer to tackle down the problem.
