3 G service control
نویسنده
چکیده
The huge investment in 3G mobile licences is an incentive to develop extra services above and beyond basic telephony and data services. Service control provides an infrastructure to deliver services, particularly those of a real-time nature. This paper focuses on the progress in developing service control in the context of the 3GPP Release 4/5 network. To achieve the objectives for service evolution, mass service development and cost-effective services, three technologies are being pursued for service control. These are CAMEL, APIs and SIP service extensions.

Optimization of M G 1 Queue with Vacation (TECHNICAL NOTE)
This paper reports on the minimization of the average waiting time of the customers in the M/G/1 queue with vacation. Explicit formula for the unknown service parameter of a particular customer has been obtained by considering the exhaustive service discipline in the case of multi-user with unlimited service system. Moreover, results in case of partially gated and gated service disciplines unde...
متن کاملOptimal Control of Service Rate in a Service Center with Lapse (Research Note)
The purpose of this paper is to analyze the effect of a particular control doctrine applied to the service mechanism of a queuing process with lapse. It is assumed that the service discipline is FCFS (first come, first served), arrival process is Poisson, service time distribution is exponential, service process is one phase and the capacity is infinite. It is also assumed that the customer may...
متن کاملSession-Based Service Discovery and Access Control in Peer-to-Peer Communications
Service Location Protocol (SLP) is a standard service discovery protocol proposed by IETF. SLP provides a flexible and scalable service discovery framework over IP networks. This paper presents an approach for service discovery and access control under session-based peer-to-peer communications. In other words, it is an approach providing mechanisms for restricting unauthorized discovery or acce...
متن کاملRouting and G-Networks to Optimise Energy and Quality of Service in Packet Networks
We formulate the problem of joint energy and quality of service (QoS) optimisation in packet networks and show how it can be formalised using the control capabilities inherent in G-network theory, which also includes the overhead due to control traffic. Using known energy consumption characteristics of network routers and of network link driver equipment, this approach leads to a polynomial tim...
متن کاملAn OGSA-Based Quality of Service Framework
Grid computing provides a robust paradigm to aggregate disparate resources in a secure and controlled environment. Grid architectures require an underpinning Quality of Service (QoS) support in order to manage complex data and computation intensive applications. However, QoS guarantees in the Grid context have not been given the attention they merit. In order to enhance the functionality offere...
