Call Processing Language (CPL): A Language for User Control of Internet Telephony Services

This thesis proposes a novel consumer-oriented Incoming Call Connection (ICC) service as an important enabling infrastructural component of the recently proposed ubiquitous consumer wireless world (UCWW), a new Consumer-centric Business Model (CBM) environment for wireless communications. The ICC solution proposed here will be offered by third-party providers who are autonomous of the access network providers. Compared to the present ICC service in the legacy subscriber-based networks, the consumeroriented ICC service will offer to mobile users greater flexibility and management control over incoming calls, enable users to receive incoming calls via multiple access networks/providers by means of a single identity, support user-driven, seamless, network-transparent Hot Access network Change (HAC), largely eliminate roaming charges and develop a new wireless networking business opportunity among other ben- Furthermore, the thesis elaborates a generic CBM-ICC service scenario, which shows how the CBM-ICC service offers to mobile users greater freedom and operation control over incoming calls, enables the novel attribute of users being empowered to receive incoming calls simultaneously, and otherwise, from various homogeneous and heterogeneous access networks, owned by the same or different providers, and enables user-driven HAC on active calls in keeping with, or matched to, user's Always Best Connected and Best Served (ABC&S) policies. A CBM-ICC proof-of-concept system-level testbed is implemented to perform experimental tests, probe different communications scenarios, evaluate the service performance, and further elaborate the service architecture. In this, approaches towards evaluating the performance of the CBM-ICC service based on designed testbed are elaborated, and sample numerical results are presented and analyzed.

“…We defined a service creation script language named Language for End System Services (LESS) [3]. LESS is extended from the Call Processing Language (CPL) [23], but with more emphasis on end system service creation. We choose to use LESS as the service creation language for SIPC because it is designed to be simple, easy to understand, and safe for end users to use.…”

Abstract. Integrating multiple functions into one communication user agent can introduce many innovative communication services. For example, with networked appliance control, a user agent can turn off the stereo when receiving an incoming call. With location sensing, a user agent can automatically reject a call if it knows the location preference is 'quiet'. Multi-function interactions enable services that are otherwise impossible. In this paper, we first present the new services introduced by the integration, then introduce our SIP user agent, SIPC, which handles these new services in a programmable way. SIPC integrates multimedia call setup, networked appliance control, presence handling, Internet TV, instant messaging, location sensing, networked resource discovery, third-party call control, real-time multimedia streaming, emergency call handling, and conference floor control into one application. We analyze the relationship among these functions and propose different approaches for function integration. SIPC uses the Session Initiation Protocol (SIP) for multimedia call setup and the Language for End System Services (LESS) for service programming.
