Mobile-to-Mobile Multimedia Service Provisioning in the IMS Using REST-Based Mobile Services

Abstract

 Abstract—With the merging of IP and TelCo networks, Mobile-to-Mobile (M2M) social networks are to be unfolded as an ultimate telecom business in the near future. By M2M, both service provider and service client are aimed to be mobile based. Hence considering mobile devices to be resource constrained and mobile networks as low-bandwidth networks, provisioning high-profile multimedia services is not somewhat straight forward. The Quality of Service (QoS) has always been a great concern in this scenario. Additionally in M2M service networks, the direct IP accessibility of mobile devices is a bottleneck in seamless communication. The cellular operators typically block every incoming http access to subscribers devices inside and outside the network due to huge traffic load and security reasons. The paper addresses the issues faced in M2M service networks and presents a solution based on the IP Multimedia Subsystem (IMS). Similar to SIP Application Servers (AS) in the IMS network, the concept of Mobile Application Servers (Mob-AS) is introduced in order to host and execute multimedia services from a mobile device. A comprehensive design of Mob-AS is presented based on the existing REST interfaced synchronous and asynchronous mobile server framework.
