Abstract

Hitherto, owners of private service control points (SCP) have been unable to co-operate with existing service applications of a network SCP. The invention overcomes this problem.

Description

description

Network SCP of an IN network

The intelligent network (abbreviated IN) for example PSTN / ISDN is a known network architecture to provide telecommunications services.

FIG I shows a known IN rchitecture. The intelligent network is designed to enable a network operator, new services (services) introduce quickly and easily, without having to make it in each network node interventions in the Anlagenprograrπmsysteme.

The procedures described above are therefore limited in an IN to as few central network node, so-called service control point SCP, which are fitted in a central location with the appropriate application software for the new services, the so-called service applications, and then in a sort of "remote control "enable the individual network nodes in the network based in the art to practice the new services. the SCP of a (public or private) network operator will be referred to as a network SCP.

Said remote network nodes of the IN are also referred to as a service access nodes or service switching points SSP. They are either directly or via a signaling network connected to a service control point SCP.

A service management point SMP is used to administer the IN services by the network operator, the service provider and the service subscriber.

Network operator or service provider are keen to establish new services or improve existing services. For this, a Service Creation Environment (SCE) is used. The task of the SCE is service data and service logic (programs) to bring in the SCPs and SMPs without existing service applications or even the basic network in their functionality and integrity are concerned.

For these reasons, the status of SCE technique is now limited to the modification of existing service applications in the exactly appropriate functions (Service customization) or on building new services from function blocks with well-defined by the manufacturer functions (Service Independent Building blocks: SIB).

In both cases, only variants can by by

Manufacturers produced certain services or diene functions.

Really new diene functions can hardly be developed, in particular by the service provider, who otherwise have no access to the functions in the basic network and SCP / SMP. The opening of an SCP / SMP The Services development by third parties fails mainly due to the enormous security problems and side effects to existing services.

Such problems to cope with the known technique of "private" SCP (hereinafter referred to as the private SCP) has been developed, that of SCPs that a private service provider or even a customer (Customer), which uses its own service belong. the developed by a third party services are Associated in a physically separate, with the network SCP, run private SCP, wherein the centralized network SCP functions the necessary security (gateways) performs. the technique mentioned is known from document "Customers in Driver's Seat: private iN Control Point, R. Lüder, M. Sevcik "known hereafter as" referenced [1] ".

2 shows a to the connection of private SCPs Advanced IN architecture according to [1]. The main enhancements affect the following components:

l) Each service provider is developing its services in a private SCP computer node.

2) The private SCP (over a secure data communication network Wide Area Network: WAN) connected to the network SCP. The WAN is based on known

Industry standards, such as the Internet Protocol (IP).

3) The log messages with the basic network is exchanged via a secure gateway GW in the network SCP. The protocols (their application parts) are known and correspond to the int. Standards such as INAP, AIN or appropriate subsets thereof. The gateway GW prevents erroneous messages or unauthorized functions affect the basic network. The owner (operator) of the network SCP can specify, for example, which network functions (eg INAP operations) are released for private SCP. By refusing to disclose a specific sensitive network function by a private SCP can not be used (eg billing).

Due to the mentioned extensions of the service provider, as the owner of a private SCP, that is free to design its services and service data.

The disadvantage is that there is no cooperation (interworking) is possible with the existing service applications in the network SCP. This would be very useful and cost-saving because many service functions from the existing service applications are readily usable also for the services in the private SCP of a service provider. Examples:

- routing

- billing

- control an intelligent peripherals (for announcements etc.) Etc.

The invention has for its object to overcome this drawback.

The advantage of the invention lies in the possibility to use existing applications of the network SCP by private SCP or the Service Creation Environment private SCP.

An embodiment of the invention according to claim 8 has the advantage that the momentum is improved since the private SCP must use a logical address for calling the network SCP the advantage.

In the following, an embodiment of the invention will be described with reference to the drawing.

First, a service provider can develop as before any services in his private SCP using the SCE, which is the order specified by the gateway GW INAP, AIN

use protocol subset. The security of the base network remains ensured.

In addition, a service provider can now in his private SCP to existing single-service functions in the

Service applications in the network SCP (see Figure 2) to access and modify it, or replace it with their own developed in the private SCP functions. This is a win-win cooperation of the private SCP with the network SCP is the goal of reaching.

This can be implemented as follows:

The service applications in the network SCP are logical, ie, divided from the perspective of the private SCP, into isolated functional blocks, each representing a service function. Between the function blocks exit points (Point Call: PIC) is defined in which a diene function can be called in a private SCP.

Figure 3 and 4 show the principle of cooperation between the private SCP with the network SCP using function blocks and PICS:

In the examples shown, there is a service application in the network SCP of three functional blocks (screening, routing, charging) and four points in call (PIC 1..4) in which the withdrawal is possible in a service function in the private SCP.

Each PIC can be independent of the other PICs "disabled" or "enabled". With a disabled PIC ignores the

Control of a function block to another in just the same service application. An "enabled" PIC causes a function in the private SCP is invoked (eg via known methods such as Remote Procedure Call).

Each PIC to assign specific data of the service application corresponding to the current state of the call handling (such as the source area and the selected route in the network SCP, in the example in the figure 3). The gateway GW (see Figure 2) guarantees the integrity of these calls and their data. The PICs in the network SCP can service parameterization (customization) in the Service Creation Environment (SCE) as desired for each service provider "disabled" or "enabled" to be set, according to the private in the respective SCP service functions to be treated. Setting the PICs causes entries in a corresponding registration means (eg service application register) of the network SCP.

The supplier of the service applications (manufacturer of the network elements, SCP, etc.) tests all service applications with all meaningful combinations of PICs and the corresponding gateway GW functions. Thus, the integrity of the basic network and service applications is guaranteed.

The service provider can associate in his private SCP treatment of a service function freely with its specific data, data management functions or program software. in routing example, a customer database example, in Figure 3 with purchasing preferences of the calling customers

Basis for the choice of a route to be taken to a specialized for this account executive.

In FIG 3 a lying between two PICs function is added (the routing function between PIC2 and PIC3 here) through a service function in the private SCP.

In FIG 4 a lying between two PICs function is completely replaced (in this case the routing function between PIC2 and PIC3) by a service function in the private SCP. To this end, in an "enabled" PIC are given (here PIC 2) the return data (PIC return data) to the next PIC to the private service function, the invention offers the following advantages.:

1) The network operator can offer the service providers (customers) via the network SCP risk (no impairment of the basic network) an application that is via private SCP of the service provider individually expanded or modified.

2) service providers to expand functions quickly service applications or services and targeted offer, without having to completely re-develop complex service applications. The diene functions can be combined with other DV applications the service provider.

3) Little testing effort because the service applications are pre-tested by the supplier. Fast commissioning of specific service functions.
