METHOD AND SYSTEM FOR REMOVING SERVICE CROSS-CUTTING SERVICES

The invention relates to telecommunication systems. More particularly, the invention relates to a method and system for eliminating service conflicts in a telecommunication system. The field of application of the invention is, for example, an intelligent network service operating in a mobile communication network.

A separate intelligent network can be connected to the mobile communication network and thus a number of intelligent network services can be implemented in the mobile communication network. However, the additional services provided by the mobile network itself are capable of providing services similar to those of the intelligent network. These. the services do not receive information from each other, which may lead to incorrect services. The result is a conflict between two different networks, the intelligent network and the mobile network. For example, the GSM (Global System for Mobile Communications) GSM call forwarding services and the intelligent network availability services are based on 20 availability chains. In this way, call diverting can be done both in the GSM network switching center and in the intelligent network, whereby the services interfere with each other as the call is ·. the control information associated with the distribution is spread over two v positions.

:: 25 According to prior art, the problem is solved ·; | inter alia, by integrating a home location register of a mobile communication network, such as the Home Location Register (HLR) of a GSM network and a Service Control Point (SCP) into a single network component 30, so that their database can be interconnected; or «ii * ·· 'There is a manufacturer-specific interface between them, the format of information passing through V' is not limited. In this case, the | *. #> Service control point is free to retrieve information from the · ···. from the registry database. The solution is hardware-specific, and a relatively cumbersome way to implement interoperability between intelligent network and mobile network services.

Another known solution is a hardware-ready interface from the MSC / VLR (Mobile Services Switching Center) (MSC) to the control point of the intelligent network. The problem with these 5 solutions is specifically hardware-ready partitioning; the operator will only commit to systems supported by a particular manufacturer.

It is an object of the invention to provide a novel method and system for overcoming the above problems. In particular, it is an object of the invention to provide a new type of solution that can prevent the conflicting operation of services on different networks. An advantage of the invention is the standard independence of the device manufacturer.

As regards the characteristic features of the invention, reference is made to the claims.

The invention relates to a method for resolving operational conflicts of cellular network services in a telecommunication system comprising a cellular network, a home location register belonging to a cellular network, an intelligent network connected to a cellular network and an intelligent network; size control point for the service. According to the invention, · ·. the method of transmitting from the service control point 25 to the home location register a protocol between the home location and the mobile network visitor location register. • · «The home location register returns the subscriber data belonging to the visitor location register to the control point. In one embodiment, when a service is activated, an identifier identifying the subscriber's cellular network, such as IMSI (International Mobile Subscriber Identity), for example, is stored at a ·,! / · Control point of the service, for example a Service Data Point (SDP). '35 or equivalent.

In a preferred embodiment of the invention, the request is a RestoreData request according to the MAP protocol, 113432 3, which is used between the visitor location register and the home location register. Operation according to the Rest-Restore procedure is described in the Digital cellular telecommunications system (Phase 2); Mobile Application Part (MAP) 5 Specification, GSM 09.02, ETSI, Chapter 16.3. Advantageously, the service control point ensures the interoperability of the services based on the information transmitted by the home location register. In one embodiment, the service control point is replaced by a service node (SN, Service 10 Node), i.e., the functions of the method according to the invention are implemented by a service node.

The invention further relates to a system for eliminating operational conflicts in cellular network services in a communication system such as the one described above. In the system of the invention, the service control point includes means for transmitting a request according to the protocol between the home location register and the visitor location register for restoring space data, whereby the home location register returns the subscriber information belonging to the visitor location register to the control location. Preferably, the service control point includes means for identifying the subscriber in the cellular network, for example IMSI; to save the ID when the service is activated. The recording can be done, for example, at a service control point or at a separate service data point '*' ·. In one application, the request to send is V,! RestoreData request according to MAP protocol. Preferably, the service control point includes means 30, such as software logic, for ensuring interoperability of services based on information transmitted by the home location register.

The invention will now be described, by way of example, with reference to the accompanying drawing, in which Figure 1 illustrates a prior art interference situation; Figure 2 schematically shows a signaling according to the invention; and Figure 3 schematically shows a system according to the invention.

Figure 1 illustrates an intelligent network service control point SCP, which is connected via a control interface to an intelligent network service switching point SSP. The service switching point is connected to the GSM network switching center MSC. In addition, the pu-15 heposti VM (Voice Mail) is connected to the MSC, which is an e-mail containing voice recordings, for example, to an answering service application.

The intelligent network has activated the availability control service controlled by the service control point SCP. The goal-20 Call Completion service is based on a goal chain whereby a subscriber is chained to a plurality of terminals, which are attempted to alternate calls until a terminal responds. If no terminal is answered, the call is routed to the> 25 subscriber by the service. One possible order in the ·· 'availability chain is: 1. GSM network interface, broadband 040xxxxxxx, 2. NMT network interface, 3.

»· Fixed line subscription, 4. voicemail service.

1 The availability service establishes a call to the mobile station when the service switching point SSP, controlled by the service control point SCP, transmits to the MSC an ISUP signaling ISUP-IAM (040xxxxxxx); 1 * · (040xxxxxxx is an exemplary recipient access number; • ISUP, ISDN User Part; IAM, Initial Address · ... * 35 Message). In accordance with the Call Forwaring Ding of the GSM System Additional Mobile Subscriber Not Reachable, the exchange MSC redirects the call to the voicemail service VM because 113432 5 subscribers are offline or have closed their mobile phones. The answering service returns to the MSC the message ISUP-ANU (ANU, ANswer signal, Unqualified), which is forwarded to the service switching point SSP.

5 The availability service does not receive signaling information about the caller's answering service, but the first message carried to the accessibility service is the response message ISUP-ANU. The availability service deduces from this that the subscriber has answered the call and does not attempt to redirect the call to the NMT network subscriber, although the answering service was only the last number in the availability service.

Figure 2 illustrates the operation of the solution according to the invention. The service control point 'SCP and the home location register HLR of the mobile network 15 are connected to the standard operation of the mobile network MAP protocol or similar additional services and mobility management protocols. In the invention, the service control point SCP occurs as a visitor location register such as a database error, such as the VLR of the guest network visitor location register. The control point SCP sends a request to the home location register HLR to restore the MAP-RestoreData REQ subscriber data. The home location register HLR responds to 25 requests it has received by sending SCP all subscriber information (messages) to that subscriber's · · ·

InsertSubscriberData REQ, InsertSubscriberData ACK), · '/ _ ·' mm. information on call forwarding activity. The control point SCP uses this information in its own service logic 30 programs. Finally, the home location register HLR acknowledges the successful message exchange by saying MAP-RestoreData ACK.

Figure 3 schematically shows a system according to the invention. Mobile network 1:> 35 includes the home location register HLR. The mobile communication network 1 is connected to the intelligent network IN. The intelligent network IN includes a service control point SCP. In one embodiment, the service control point SCP and the home location register HLR 113432 6 are directly interconnected, in one embodiment a protocol between the intelligent network IN and the mobile network 1 is used. The service control point SCP 5 includes means 10 for transmitting a request according to the protocol between the home location register HLR of the mobile network 1 and the visitor location register (e.g. VLR in the GSM system) to the home location register. By means of means 10, the service control point SCP plays the visitor register-10 blades for the home location register HLR. The service control point SCP also includes means 11 for storing an identifier of the subscriber in the cellular network, whereby the control point SCP can subsequently utilize this information. By means of means 12, the control point SCP of the service 15 ensures that the service cooperates.

The method and system according to the invention can be advantageously implemented at the control point SCP of the intelligent network services, or alternatively at the service node SN. The control point preferably has access to both ΙΝΆΡ (Intelligent Network Application Part) and MAP protocols. The invention may be implemented in a variety of mobile networks, for example GSM, DCS, PCS or UMTS and IS-41 based network systems such as AMP, DAMP or IS-95.
