SYSTEM FOR THE PROCESSING OF TELECOMMUNICATIONS subscriber data

The invention relates to a system as defined in the preamble of claim 1 for managing subscriber data in telecommunication networks.

The problem with the current services offered in various networks (eg GSM, Global System for Mobile Communications (PSTN), Public Switched Telephone Network (Internet)) is that they are designed to operate only in their target country. Each network has different policies for processing subscriber data. Location services are tied to the target network and the person's reach can only be processed within a specific network. A person may be on target, for example, via the Internet in a location where the paging network is down.

The object of the present invention is to eliminate the above problem. In particular, it is an object of the invention to provide a novel system 20 in which subscriber data and services are available between different networks, and in which the services can be targeted to the particular network used by the subscriber regardless of the network interface. The system enables, among other things, an accessibility service between different networks.

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

The system of the invention transmits and modifies subscriber data in connection with at least two bidirectional communication networks that handle different subscriber-30 data. The telecommunication network is, for example, a public telephone network, a multi-service digital network, ·, a public mobile network, a paging network, a messaging network, a telex network or an IP-based network 35 (IP, Internet Protocol). The system includes means for transparently connecting the system to the communications subscriber data elements of the telecommunications 112760 2 network. Transparent in this context means that the system does not require changes to the architecture of existing networks.

5 The system includes means for logically storing subscriber data of different telecommunication networks in the same database. Database data may be distributed in different elements, but belong to a substantially unified database interpreted as a whole.

The system comprises means for exchanging subscriber data between subscriber data elements of the telecommunications network and / or the subscriber database. The subscriber information to be exchanged may be, for example, the subscriber's location, where and at what time the subscriber is available, or the subscriber's service information, which includes the services available to the subscriber.

In a preferred embodiment of the invention, the system 20 comprises means for transmitting signaling between different telecommunication networks.

In a preferred embodiment of the invention, the system comprises means for converting data types such that the subscriber data data type is compatible with the system database and data elements of the network element of the telecommunication network associated with the system.

In a preferred embodiment of the invention, the system comprises means for a subscriber's service profile. 30 to form an Iin. The subscriber's service information can be used to deduce the network and service that the subscriber preferably uses.

; In a preferred embodiment of the invention, the system comprises means for verifying operation. The system is a critical component for network-independent services.

In a preferred embodiment of the invention, the system is implemented in a terminal. The services are then implemented and activated for each subscriber's terminal equipment separately and taking into account the characteristics of each of the 5 networks.

In a preferred embodiment of the invention, one of the means included in the system is implemented as part of a network element. The system means may be formed as a module to be connected to a network element of an existing information traffic network.

An advantage of the system according to the invention is a uniform external interface for the information of service users for use in, for example, customer management systems. The system enables the establishment of 15 more advanced accessibility services, where the subscriber can be reached through one connection from several different telecommunications networks. The system saves the capacity of the networks. Searching for a subscriber from other networks can be performed as a simple search from the directory 20, and the search service does not require the establishment of a complete telecommunication connection. In practice, subscriber data can be managed in real time when the system is placed in a subscriber information exchange system; mentions. In other words, the lookup service can be: 25 implemented as a simple character change.

In the following, the invention is described in the following. with reference to the following silicon; Fig. 1 schematically illustrates a system according to the invention, and Fig. 2 illustrates another embodiment of the invention as part of existing network elements.

Let us consider as an example the processing of the location data of a subscriber. When connecting the system according to the invention 2 to GSM network 3, it is connected to MSC / VLR 4 (Mobile Services Switching Center / Visitor Location Register) and HLR 5 (HLR, Home Location Register 112760 4 ter). ) between the means la. As MSC / VLR 4 exchanges information with HLR 5, communication goes through system 2 which extracts the information it needs from the traffic and forwards the traffic to HLR 5 without changing the messages between MSC 4 and HLR 5. Thus, the system 2 has obtained the subscriber's position information from the GSM network 3 by filtering the communication between the MSC / VLR and the HLR.

The position information is stored in the system 2 database 10 of the system 2 by means of the means 13. This information could be utilized, for example, in an Intelligent Network (IN) provided by the PSTN 6, where the Service Control Point 7 (SCP) requests subscriber information from the Service Data Point 15 (SDP). Instead of the service data point 8, the query is redirected to the system 2 by means of Ib, which can immediately return the subscriber data or redirect the original query to the service data point 8. After receiving the service data point 8 20, the system 2 can add the desired data to the service data point 8 and return the response

A similar policy can also be used in TCP / IP network 9 (TCP / IP, Transmission Control Protocol-25 inch / Internet Protocol), where system 2 can act as a server for various directory services. In one example, system 2 is connected to the gatekeeper 10 and terminal 11 defined by the ITU (International Telecommunications Union) standard family H.323, via means le. The terminal 11 registers with the ga-tech family 10 and inquires about call setup information. The communication passes through system 2, which filters the information it needs from the communication. The communication between the terminal 11 and the gatekeeper 10 operates as in a network which does not use the system 2 according to the invention.

For example, a much more advanced accessibility service can be implemented as described above. When reaching a subscriber, for example via the GSM network, a message may be left in the subscriber's answering machine 5. This message is transmitted according to the service profile of the subscriber formed by the means 15 to a network considered most suitable, for example the Internet, where the message left on the answering machine is converted into an email message. System 2 always has subscriber data for a network of ten, e.g.

The load of the system according to the invention is controlled because in existing networks, the subscribers can be divided into network components containing different subscriber data so that only the subscriber data and related search and processing operations using independent services are routed through the system using appropriate signaling. The system 2 is provided with means 14 for transmitting the character 20.

In system 2, it is essential to combine subscriber data, location and service information into the same system with signaling between different telecommunication networks. System 2 acts as a gateway between: 25 different networks. Since the subscriber data of all the networks connected to the system 2 are collected in the same database, communication between two different networks can be established directly between the networks without having to check the subscriber data through any of the third networks. System 2 also operates in real-time in practice, in contrast to known methods, which rarely process subscriber data in batch mode, while simultaneously collecting data from multiple subscribers.

Figure 2 illustrates a system according to the invention in which the means of system 2 are implemented as part of existing network elements. The system 2 of system 112760 6 is physically distributed as additional modules built into various network elements that perform the functions of system 2.

The invention is not limited to the above-described embodiments only, but many modifications are possible within the scope of the inventive idea defined by the claims.
