The invention relates to a method, system and computer program product for provisioning in a communications network. According to the method at least one request is received form a client system ( 11, 30 ) through an Application Program Interface (API, 12, 13 ) and Management User Interface ( 48, 49, 58, 59, 93 ) for defining measures relating to customers and/or services and/or network elements ( 18, 19, 20, 21, 72 ), each request is processed in functional layers ( 80, 81, 82, 83 ) of the provisioning system hosted by network operator ( 1, 2 ). Tasks are executed according to the results of the processing step, and the results are reported to the requesting entity. According to the invention service operators ( 3, 4 ) are allowed to use the provisioning system ( 15 ) through authenticated Application Program Interface (API, 40, 50 ) and authorisation function ( 43, 53 ) after the provisioning rules processing ( 94 ) where the rights for the use of the network elements ( 18, 19, 20, 21, 72 ) are controlled by the network operator, whereby the network operator is able to present and utilize one physical network in many logical views, each representing the portion accessible for virtual operator, and in this way controllable by network operator with limitations, authentication and authorization rules.
