Definitions
- Switching centers in telephone networks are typically closed systems, i.e. both the implementation of the supported functions, such as Structure of calls, charging, statistics, as well as the hardware basis are manufacturer-specific.
- Network operator of the supported functions such as Structure of calls, charging, statistics, as well as the hardware basis are manufacturer-specific.
- Telecommunications networks must therefore coordinate their specific requirements for switching center functions with the manufacturers, who then implement these on behalf of the network operators.

- a classic switching center with an additional platform based on commercial hardware (HW) and software (SW), e.g. the standard operating system UNIX, on which special modules (application blocks) are implemented, whose functions can be controlled externally via open APIs.
- This platform allows the network operator to develop their own telephone value-added services in a commercial software environment based on application programming interfaces (API) for switching center functions.
- API application programming interfaces
- the exchange and the commercial platform communicate via an internal interface, which is not standardized and whose functionality depends on the requirements of the software modules to be supported on the commercial platform.
- Different applications can be implemented on the commercial platform: protocol conversion applications that can offer the standardized APIs and other applications that can offer non-standardized APIs.
- a difference and advantage of the method according to the invention compared to existing IN SCEs and other systems that only have standardized protocol interfaces to switching centers is the possibility of basically having free access to all switching center functions via the internal interface between the commercial platform and switching center to be able to use for the implementation of the applications according to the invention on the commercial platform.
- a second difference between the method according to the invention and existing IN SCEs and other systems that only provide standardized APIs lies in the idea of non-standardized APIs for higher-quality service functionality
- Each of these service application blocks has access to the call processing functions of the exchange via the internal interface.
- the basic function of a service application block is fixed, e.g. Establishing a connection in the PSTN between two subscribers that can be reached via an E.164 address, including creating a greeting or initializing fee tickets for each subscriber in the exchange.
- open APIs enable the activation of the respective service functions as well as the control of individual performance features.
- the service application block "Automatic establishment of a connection between two PSTN subscribers" which of the two subscribers takes over the fees, whether a standard announcement or a personal announcement is to be played as a greeting (requires transmission of the address and identification of the personal announcement ) or whether status information about the connection should be reported back via the API (e.g. subscriber busy)
- the method according to the invention therefore includes the approach of not opening the call processing functions of a switching center directly to the outside via APIs, but first of all to define service application blocks on the commercial platform belonging to the switching center, in which the service-specific interworking with the existing network functions and their functions are solved can be controlled via open APIs.
- Network operators can activate and combine these service application blocks as desired and thus create new value-added services.
- the actual service logic of the one created by the network operator Value-added service on any server in the network.
- the service application blocks with their defined APIs serve the network operator as building blocks for implementing their own value-added services (see exemplary embodiment under 5.)
- the interworking of the service application blocks with each other is supported by a so-called session manager application block. All application blocks that process active service requests via their API make a registration for every active service user in Session Manager.
- the Session Manager offers an internal API for this. If a service request is ended, a deregistration takes place.
- the session manager thus always has a current image of all active service requests. Its data can be read by any application and thus support interworking between different service application blocks.
- a major advantage of this method is that the user of the APIs for service application blocks does not have to have detailed knowledge of existing network functions. In particular, all details of the respective signaling system of the basic network are completely transparent at the level of the API user, and the internal interaction between the switching center and application block covers all possible interworking cases.
- This method allows the definition of robust and easy-to-use APIs, since the defined scope of each service application block or API limits possible errors and can be tested by the manufacturer.
- the standardized APIs PARLAY, JAIN, 3GPP, etc.
- These APIs are very complex and require the transfer or control of a great deal of control information.
- the figure shows the basic division of functions between the switching center with an integrated commercial platform that offers open APIs (backend server) and the external application servers that use these APIs (front end server).
- the commercial platform contains several application blocks with a defined range of functions that can be controlled using open APIs.
- the functions of the application blocks use the core call control functions of the underlying exchange via an internal interface.
- the network operator's value-added services are implemented on separate application servers in the network. They use the open APIs of the commercial platform to initiate actions in the basic network (eg establishing a connection between two participants) or via events in the basic network to be informed (e.g. subscriber busy, incoming call).
- the open APIs are used on the basis of CORBA - this means that the implementation of the software on the application server and its hardware is independent of the software and hardware of the commercial platform.
