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