There is an increasing trend of accessing multimedia and web services embedded with Presence service over the mobile, which have driven the telecom operators to look for the new and better ways to provide such services. Presence service puts a lot of load on the IMS network and it can contribute 50% or more to the total signaling load which can increase end-to-end delay. In this paper we have analyzed...
Parlay is an efficient and flexible approach that enables telecom operators to efficiently wrap up their network services and capabilities and allows third parties to flexibly access those services for deployment of new applications that drive consumption of network services. This paper describes an Internet-mobile platform for telecom applications based on Parlay X. Our solution aggregates resources...
Based on the investigation on current convergent methods for IMS services and Web 2.0 services, a Component Based Convergent Services Architecture (CBCSA) is proposed. The architecture and the work mechanism of CBCSA are discussed in detail. By fully making use of COM characteristic, the Telecom services can be composited freely and the Web 2.0 services and Telecom services can cooperate efficiently...
Telecommunication networks are service centric and therefore benefit from service composition techniques in accordance to Service Oriented Architecture (SOA) principles. Furthermore, services in the telecommunication domain are subject to specific requirements such as support for end-to-end communication sessions and mechanisms for service interaction across technological borders including telecom,...
IP Multimedia Subsystem (IMS) is a platform for service provisioning over IP networks, standardized by 3GPP. One of the key concepts of this technology is service enablers. Enablers are reusable modules encapsulating certain network functions, in order to simplify the development of new network services. In this paper, we present GroupManager, an enabler for group management that provides improved...
TELCO operators are moving towards adopting the role of platform providers that enable developers or third parties to create new services for their platform. This is similar to the Web 2.0 application development paradigm where developers use existing frameworks and software development kits to create portable services through mashups (composition) and syndication. To attract a community that would...
In this paper we suggest an approach to quality of service based charging in Internet protocol multimedia subsystem (IMS) by the use of Parlay X Web services. The policy and charging control (PCC) functions are analyzed and their support by Parlay X interfaces is evaluated. The open access to application-driven quality of service and payment functions is investigated and mapped onto IMS control protocols...
A new mobile next generation network (mobile-NGN) architecture based on the REST (representational state transfer) concept is proposed. In this architecture, mobile communication services are established by combining distributed network resources such as access networks and consumer information management servers derived from REST technology the same as for Web services. This architecture is designed...
Major success factor for the futuristic IP Multimedia Subsystem (IMS) based network is dynamically delivering a blend of one or more services simultaneously to the end-users based on their preferences and context. Such blended services, can range from triple play to dynamic context based services. To deliver such services 3GPP introduces a functional block called SCIM (service capability interaction...
The evolution to IP-based next-generation networks, the widely adoption of IMS by both fixed and mobile service providers and the need to better integrate enterprise solutions with telecom services are expected to drive a new wave of enhanced services that will seamlessly combine IT and telecom technologies. Telecom service providers have great expectations from these new networks, helping them to...
