Embodiment Construction

[0033] Figures 1, 2 and 3 show the possibilities known from the prior art how the functionality of a private branch exchange can be realized.

[0034] In FIG. 1 , the private branch exchange 13 is installed as a separate device at the customer and is connected via a connecting line 15 to a switching node 14 of the public network, which is not shown in more detail. The user terminal equipment is depicted as a telephone. The administration of the functional features of the private branch exchange subscribers takes place decentralized here by the customer, that is to say by the operator of the private branch exchange (PBX operator).

[0035] In Fig. 2, the functions of the private branch exchange are exchanged as software on the platform of the public switching center 14 (hosted PBX). Even in the case of such a PSTN-based Centrex, the Centrex subscribers are connected to the switching node 14 via a line 15 in a line connection. Subscriber-specific data are located on a central ...

Abstract

Disclosed is a method for administering functional Centrex characteristics which are made available to Centrex users (A, B, C) in a first communication network (1) of a Centrex client by a Centrex service provider on a network element (11) of a second, packet-oriented communication network (2), a transmission channel (3) establishing a connection between the Centrex users (A, B, C) and the network element (11). The inventive method is characterized in that the Centrex client obtains a user authorization from the Centrex service provider for an allotment of functional Centrex characteristics while a digital certificate containing an attribute with a Centrex profile in which an association between functional Centrex characteristics and a Centrex user is defined is issued to at least one Centrex user by a Centrex client's certification authority, and at least one functional Centrex characteristic is isolated in the network element in accordance with the certificate previously transmitted to the network element by the Centrex user via the transmission channel.

Description

technical field [0001] The invention relates to a method for managing Centrex functional features provided by a Centrex service provider to a Centrex user in a first communication network of a Centrex customer on a network element of a packet-switched second communication network, wherein the transmission channel Establish the connection between the Centrex user and the NE. Background technique [0002] In telecommunication technology, the concept Centrex (Central Office Exchange) is generally understood as the exchange of the function of the private branch exchange (Privat Branch Exchange PBX) to the public telephone network. The telephone provider or the Centrex service provider provides the Centrex function on the platform of the public exchange node or the Centrex server for the closed user group of Centrex customers. In both cases the Centrex functionality is installed on the client machine and is therefore also referred to as a "hosted PBX". [0003] Currently, the c...
