OMA DM based remote RF signal monitoring of mobile devices for QoS improvement

Abstract

As mobile devices and functionalities have increased and become intelligent, many related problems have occurred. Especially, the degraded quality of service caused by the shadow area has given the end-users much inconvenience. In addition, the credibility of the service providers, the network operators, and the manufacturers of the mobile devices have also decreased. In order to solve these problems, we need to monitor the radio frequency (RF) signal related information such as me received signal strength (RSS) for finding the shadow areas. So far, no appropriate method has been given. In oris paper, we propose a RF signal monitoring method for the quality of service (QoS) improvement based on the Open Mobile Alliance (OMA) Device Management (DM) standard. We have defined the management objects (MOs) for finding the shadow areas and design the management operations for collecting the MOs at the central server. We have developed based on MOs and the management operations. We also present the result of the performance evaluation of our proposed management operations. © IFIP International Federation for Information Processing 2007.
