Embodiment Construction

[0035] In one embodiment of the invention, the task of the feature-interaction-manager is to correctly assign events generated by the basic switching system BSN to live, activated or to-be-activated features (see figure 2 ).

[0036] If a certain functional feature has been activated or called, then the main task of the invention of the functional feature-interaction-manager FIM is to, in the presence of an additional functional feature-requirement (=activation) (FReq) Or perform a compatibility check when calling an event.

[0037] This means that a compatibility check is carried out between the requested functional feature and the already activated or active (=called) functional feature.

[0038] A further task of the feature-interaction manager is to ensure the user's requirements for feature coordination and thus to monitor the hold feature-performance.

[0039] Furthermore, the feature-interaction manager also ensures the coordination of coexisting features, ie avoids t...

Abstract

The invention concerns a method of resolving performance feature interactions (FI) in a communication system with decoupled network control (BSN) and performance feature control (FN) with a plurality of performance feature (LMi, LMj). The performance features (LMi, LMj), which each act differently on different user connection units (A, B, C, D; DeviceA, DeviceB, DeviceC), are correspondingly divided into a plurality of roles (Rollei1, Rollei2, Rollei3, Rollej1, Rollej2) which are transferred to individual user connection units (A, B, C, D; DeviceA, DeviceB, DeviceC) during the respective performance feature sequences. Thus, before a new role (Rollei1, Rollei2, Rollei3, Rollej1, Rollej2) is accepted, its compatibility with already accepted roles is checked. If necessary, special actions are also carried out in order to ensure that there is the specified interaction between the desired performance features (LMi, LMj), that all the roles accepted coexist and that stoppages in the operational sequence are avoided. A communication system suitable for performing a method of this type and having decoupled performance feature control (FN) and network control (BSN) which intercommunicate via an interface contains a performance feature interaction manager (FIM) which is associated with the performance features control (FN) and is disposed in the region of the interface for resolving the performance feature interactions (FI).

Description

technical field [0001] The invention relates to a method of decomposing the interaction of functional features in a communication system with exchange control and performance feature control decoupled from each other, that is to say in a so-called IN-style architecture (IN here means Intelligent Network). Method and a device. Background technique [0002] Today's switching systems support many features. They are some ancillary services of telecommunication such as [0003] - Call Forwarding CFU [0004] - Call forwarding CFBS when busy [0005] - Call forwarding CFNR when idle [0006] -Speed ​​Dial SD [0007] - Selective call protection TCS [0008] -Reply to CC, Relay to CA, Transfer to CT [0009] - insert CO, answer insert TCO [0010] - conference call CONF [0011] - Automatic call back to ARBS when busy [0012] There are two different types of functional characteristics. One is an explicitly activated (FReq) feature, wh...
