Virtual Network Capacity Expansion through Service Outsourcing.
Conference: WCNC 2008, IEEE Wireless Communications & Networking Conference, March 31 2008 - April 3 2008, Las Vegas, Nevada, USA, Conference Proceedings
Roaming agreements in 3G and beyond 3G networks can greatly enhance the delivery of services to end users. The cost of service delivery to the user depends on the price charged on networks traversed by user traffic. In a QoS DiffServ environment, network resources may be sold in aggregate blocks at wholesale prices to competing ISPs. This can influence the cost of delivering services between two points using access networks owned by competing operators. Demand for network services by users varies over time and network capacities are finite; thus a fully loaded network would reject new service requests and an underutilized network will become less productive. In this paper we explore a service outsourcing scheme between competing operators that allows a custodian network operating at full capacity to outsource service provision to a candidate network. Outsourcing would be price-influenced enabling the home (custodian) operator to levy local predictable charges to the end users for services offered on the visited network. This will virtually expand the capacity of the custodian network and boost incomes for both operators.
Conference Paper: Service outsourcing to support virtual home environments (VHE)[Show abstract] [Hide abstract]
ABSTRACT: In a virtual home environment (VHE), mobile users may access all services available on their home network, in the same manner and with the same level of service performance. Interaction between users, their home networks and candidate visited networks should be planned for service discovery, and QoS and price negotiation. A further aspect for consideration is the use of networks owned by unaffiliated operators that are candidates for facilitating the VHE, when the affiliated visited does not support the requested service. In this paper we explore VHE aspects and scenarios with the aim of introducing service outsourcing. We extend our earlier work on service outsourcing to VHE where services are outsourced to a candidate network if the custodian visited network cannot meet critical VHE requirements for a user. Through numerical analysis we show that if agreed roaming prices are charged for services delivered on an unaffiliated candidate network wider service usage will occur in VHEs.LCN 2008, The 33rd IEEE Conference on Local Computer Networks, The Conference on Leading Edge and Practical Computer Networking, Hyatt Regency Montreal, Montreal, Quebec, Canada, 14-17 October 2008, Proceedings; 01/2008
Conference Paper: Real-time resource sharing through service outsourcing[Show abstract] [Hide abstract]
ABSTRACT: Service outsourcing is a mechanism that allows competing operators to share network capacity and provide services to their subscribers for mutual benefit. An operator (custodian) who is experiencing an overshoot in the peak demand for network resources can negotiate an SLA with a competing but federated network (candidate) to provide network access for users of arriving service requests. Two main categories of operators emerge on custodian and candidate sides. Optimistic operators are those who utilise any available opportunity to partake in outsourcing, whereas pessimistic operators would rather avoid outsourcing than risk the financial implications of outsourcing. In this paper we explore the features of service outsourcing and analyse the character of participating operators. Moreover, we present various test scenarios and results involving service outsourcing between two networks. The scenarios explore the profitability of operators who participate in outsourcing when compared to those who don't.Local Computer Networks (LCN), 2010 IEEE 35th Conference on; 11/2010
