Abstract:
An infrastructure for data transmission, comprising:a network (N) with connection points (11, 12) for subscribers (A, B); a service provider (SP) coupled to the network (N); in which the network (N) comprises a service switching function (SSFN) as well as a service control function (SCFN) for controlling the service switching function (SSFN); in which the service provider (SP) comprises a service switching function (SSFS) as well as a service control function (SCFS) for controlling the service switching function (SSFS); in which the service control function (SCFN) of the network (N) has at its disposal a set of generic instructions which are available to the service control function (SCFS) of the service provider (SP); in which the service provider (SP) comprises an inter-working unit (IWU), said inter-working unit (IWU): being connected, via a first functional interface (CM1), to a service switching function (SSFS) of the service provider (SP), said first functional interface (CM1) being such that the inter-working unit (IWU), in the communication with the service switching function (SSFS) of the service provider (SP), behaves as service control function (SCFS); being connected, via a second functional interface (CM2), to a service control function (SCFS) of the service provider (SP), said second functional interface (CM2) being such that the inter-working unit (IWU), in the communication with the service control function (SCFS) of the service provider (SP), behaves as service switching function; being connected, via a third functional interface (CM3), to a service control function (SCFN) of the network, and being connected, via a fourth functional interface (CM4), to a service switching function (SSFN) of the network, said third and fourth functional interfaces (CM3, CM4) being such that the inter-working unit (IWU), in the communication with the service control function (SCFN) and the service switching function (SSFN), behaves as special resource function (SRF).
