Method for making available features for alternative connections of primary connections

A method for creating an alternative communication connection to a communication connection from a first gateway of a first subscriber via a primary network to a second gateway of a second subscriber, the communication connection having a data path and a signaling path, the method comprising:

• detecting a fault in the signaling path of the communication connection of the primary network;
• and
• in response to detecting the fault:
• creating an alternative communication connection having an alternative signaling path via an alternative network and a call processing server, the alternative signaling path created independently of the data path, the call processing server centrally controlling the first and second gateways;
• logically linking the signaling path of the primary network with the created signaling path of the alternative network;
• storing, in the call processing server, a feature of the communication connection of the primary network relating to connection data which is provided by the signaling path of the primary network such that the feature is available in the call processing server for the alternative signaling path of the alternative network,
• retrieving the stored data by the call processing server;
• and
• transferring the retrieved data by the call processing server directly via the alternate signaling path,
• wherein in the case of an invalid data path, between a calling terminal allocated to the first gateway and a called terminal allocated to the second gateway, the method further comprises:
• requesting the first gateway to reach the called terminal under an alternative call number for the alternative network;
• storing a feature of the invalid data path;
• linking an originally dialed call number and the alternative call number;
• recording an incoming connection request at the second gateway;
• identifying an incoming part of the alternative communication connection;
• requesting the stored feature of the invalid data path;
• and
• signaling the incoming connection request to the called terminal.

A call processing server for executing switching functions on the internet, wherein the server is adapted for performing a method for creating an alternative connection to a communication connection from a first subscriber via a primary network to a second subscriber, the communication connection having a data path and a signaling path, the method comprising:

• detecting a fault in the signaling path of the communication connection of the primary network;
• and
• in response to detecting the fault:
• creating an alternative signaling path via an alternative network, independently of the data path;
• logically linking the signaling path of the primary network with the created signaling path of the alternative network;
• storing a feature of the communication connection of the primary network relating to connection data which is provided by the signaling path of the primary network retrieving the stored data by the call processing server;
• and
• transferring the retrieved data by the call processing server directly via the alternate signaling path.

A method for creating an alternative connection comprising:

• providing a first communication connection between a first gateway for a first subscriber and a second gateway for a second subscriber, the first connection comprising
• a data path between the first and the-second gateways via a primary network, and
• a signaling path via the primary network and a call processing server;
• detecting a data path failure;
• detecting a signaling path failure;
• in response to the data path and signaling failures:
• creating an alternative communication connection comprising:
• a data path between the first and second gateways via a first alternative network, and
• a signaling path via a second alternative network and a call processing server;
• and
• storing a feature provided by the first connection such that the feature is available to the alternative connection.
