Presented work focuses on proposal of new service deliv-ery method based on innovative idea of sharing servicesamong operators and service providers. The proposal isaimed to extend architecture of IP Multimedia Subsystem(IMS) in order to enable service sharing. The extensionis named Service sharing System (SSS).IMS architecture supplement is defined as applicationserver, its structure, blocks, relationships and communi-cation among involved entities is proposed.The reason for such extension definition is that the IMSis for upcoming decade preferred communication technol-ogy focused on delivering multimedia services. With itsservice-oriented and layered architecture it enables pro-visioning of variety of services and adoption 3rd partyproviders’ services.However, communication network operators are loosingmarket share of service providers at expense of Apple’siPhone and Google’s Android. If they want to reversethe trend of becoming only Internet connection providers,they need to focus on customers’ satisfaction and offervariety of interesting services. Such requirement can befulfilled by changing their ”Walled garden” thinking andopening their environments to 3rd party service providers.For this purpose we propose mentioned Service SharingSystem.SSS offers listing and categorization of services, whichdoes not exist in any former nor current communicationnetwork. Compiled of services offered by home operatorand other service providers, the list of services is presented to customers, which can browse it, choose a service (e.g.TV stream) and use it regardless of who provides it.The solution is win-win for all involved parties while itbrings higher quality and variety of services to customerswhile producing higher income for operator and also forservice provider.
