Method and arrangement for resolving performance feature interactions in a communication system

Abstract

A method is indicated for resolving performance feature interactions (FI) in a communication system with mutually decoupled switching control (BSN) and performance feature control (FN), having a plurality of performance features (LM.sub.i, LM.sub.j). The performance features (LM.sub.i, LM.sub.j) , which respectively act differently on different subscriber terminal units (A, B, C, D; Device.sub.A, Device.sub.B, Device.sub.C) are correspondingly divided into several roles (Rolle.sub.i1, Rolle.sub.i2, Rolle.sub.i3, Rolle.sub.j1, Rolle.sub.j2) that are taken on by individual subscriber terminal units (A, B, C, D; Device.sub.A, Device.sub.B and Device.sub.C.) in the course of the respective performance feature sequences. Before the taking on of a new role (Rolle.sub.i1, Rolle.sub.i2, Rolle.sub.i3, Rolle.sub.j1, Rolle.sub.j2), its compatibility with roles already taken on is hereby respectively tested. If warranted, specific actions are additionally carried out in order to ensure the specified interaction of the desired performance features (LM.sub.i, LM.sub.j) , the coexistence of all roles taken on and the avoidance of deadlocks of the functional sequence. A communication system suited for carrying out such a method, having mutually decoupled performance feature control (FN) and switching control (BSN) that communicate with one another via an interface, contains a performance feature interaction manager (FIM) for the resolution of the performance feature interactions (FI), which manager is allocated to the performance feature control (FN) and is arranged in the region of the interface.
