Service flow control procedure in telecommunication networks. Object of the invention

The following invention, as expressed in the statement of the present specification, refers to a procedure for controlling the flow of services in telecommunication networks, with the essential purpose of ensuring that the connections of the flow of services provided are made through operators with a valid telecommunications network license to offer the services and know the complete path followed by the flow of connections established by the subscribers for the different services.

Likewise, another objective of the invention is to be able to establish quality metrics or controls parallel to the traditional systems of telecommunication network operators. Scope

This document describes a procedure for controlling the flow of services in telecommunication networks, which is applicable by all telecommunications network operators and is especially applicable in international telecommunications. Background of the invention

As is known, when a subscriber uses a service offered by a telecommunications network operator, a logical link is established between the device of the person who requires the service and the entity that offers it.

Examples of this entity would be a server that provides information, music or data, a telephone in the case of a telephone call, etc.

Thus, the network operator (of the subscriber that requires the service) will search for the entity that will satisfy the service, so that the way to do it varies greatly by service and technological implementation. Thus, in the case of a data connection, this will be done with the server's IP address, in a phone call it will analyze the dialed number, etc.

When the entities to be connected are in different operators, the latter must have one

or several points of interconnection between them so that the communication takes place.

In the case of an international connection, it is common that there are multiple operators involved by whom the connection will transit through its interconnection points.

In either case, this process is known as "routing."

On the other hand, in all cases, the operators of the different telecommunication networks will have previously reached a commercial agreement that will include the billing mode of the services between them.

To be able to do this, the devices used by the operators keep records for each of the connections, keeping the necessary details to be able to invoice the service.

In addition, due to the multitude of different paths that a connection can take especially in the international case, it is very difficult to establish which was the complete path followed to connect both entities, since each operator in the chain followed to connect has “visibility” on what transits in your network but does not have "visibility" connect.

Thus, it may happen that in the destination country fraudulently, an intruder has a device connected to international and national networks at the same time without having a valid license to do so, so that he picks up international calls and transmits them as national, It has a direct impact on the national operator in loss of income due to international fees and for the State in cases where there is a tax for international termination. Description of the invention

This report describes a procedure for controlling the flow of services in telecommunication networks, with the essential purpose of ensuring that the connections of the flow of services provided by telecommunication networks are made through operators with a valid license to offer the different services and, in addition, to know the complete path followed in the connections established by the subscribers, so that the procedure is based on:

•

a system of continuous generation of service connections that are monitored and made from the place of establishment (country of origin) of the connections to the target network, said service connections being injected with known parameters to the "gateway" where they are recorded, said parameters, in a first memory;

•

a collection system based on probes that capture the interconnections produced between international operators and operators of the destination (country of destination) and record the individual messages of each connection in a second memory, and;

•

a mediation and correlation system that compares the recorded information of the individual messages in the second memory of the collection system with the service connections injected and monitored by the generation system,

so that if any of the individual messages recorded in the second memory of the collection system is not in the service connections injected and monitored from the place of establishment of the service connections, it is indicative that not all interconnections are being monitored with the national operators of destination.

In this way, by means of the process object of the invention, it is a question of solving the inconveniences related to the existing difficulty in knowing the complete path followed, mainly, when it comes to international communications, to connect a subscriber.

The combination of the three systems mentioned above identifies the connections of the service fl ow that pass through the interconnection points of the probes and those that are monitored generated by the generator system that reach the gateway and have been detected by The probes

The connections that arrive at the gateway and have not been detected by the probes are registered individually and investigated by the national operator to detect the entry point.

To complement the description that is going to be made below, and in order to help a better understanding of the characteristics of the invention, the present descriptive report is accompanied by a set of drawings, in which the figures are illustrative and not limiting , the most characteristic details of the invention are represented. Brief description of the designs

Figure 1. It shows a view of a scheme related to the road followed by a series of international connections, being able to observe how one of the connections, at the destination, is not interconnected through a valid licensed operator.

Figure 2. It shows a view of a scheme related to the road followed by a series of international connections, being able to observe how through the system object of the invention is located that connection that is not interconnected, at the destination, to a licensed operator valid. Description of a preferred embodiment

In view of the aforementioned figures and according to the numbering adopted, we can observe how in Figure 1 of the designs a scheme is represented on the path followed by a series of service connections in international telecommunications networks, being able to observe as one of The connections, in the place (country) of destination, are not interconnected through a valid licensed operator, but through a computer connected to international and national networks.

Thus, starting from a user 1 who initiates a communication in a country P1 to destination 2 in another country P3 and having traveled through a third country P2, the said communication can follow, one of the paths, 3, 4 or 5 according to different operators (a1 , a2 and a3), (b1 and b2) or (c1, c2 and c3), so that the roads3 and 4 get to interconnect with an operator IC1 and IC2, respectively, of the country of destination of the connection, with a valid license, through which the connection arrives at destination 2, while on route 5 it is interconnected to an “X” device connected to international and national networks at the same time and without having a valid license for it, captures the international connection and Send to destination 2 as if it were a national call.

In order to solve this problem, a procedure is described by means of which it is possible to have all the information related to the flows of service connections established within a telecommunication network, for which all the entry points are controlled with a check mechanism to cause an alert when some point is not controlled, so that the procedure is based on the conjunction of the following three systems:

• Generation system 6.-This system is responsible for establishing continuous connections 7 of the service or services that you want to monitor from the place of establishment of the connections to the target network, that is, the destination network 2 of the subscriber connections , injecting these connections 7 with known parameters, such as IPs or subscriber number, recorded in a memory 8 of the "gateway" 9. In this way, there will be a universe of known communications between the generator 6 and the "gateway" 9 that later they will be contrasted with those detected by the collection systems at the international interconnection points.

• Collection system.-This system is based on 10 probes installed in the interconnections between international and national operators of the destination of the connection and whose system records individual messages in a second memory 11.

Thus, this system can take different forms depending on both the service in question and the technology used, although its principle is always the same, to capture the necessary signaling to establish the service.

Typically, to establish a single session, several messages are exchanged between two or more network entities (subscriber and service), having some element that allows the messages belonging to the same session to be related to each other.

This system captures and records in a second memory 11 the individual messages with the level of detail necessary to later be able to reconstruct the session with the necessary information.

• Mediation and correlation system.-This system is responsible for collecting the individual messages recorded in the second memory 11 by the capture system and correlating the individual messages that make up a session to be able to reconstruct the succession of events by reconstructing the communications made in each point.

Once the information of the individual sessions is available at the international interconnection points, the connections (communications) 7 of the sessions injected by the generation system 6 are searched to be sure that all the information in the network is available. If any of these communications is missing, it must be reviewed that the collection system is monitoring all possible points of entry to the network.

The combined use of the three systems allows to have the necessary information to identify the connections (sessions) that passed through the interconnection points and those that were generated by the generation system 6 and arriving at our “gateway” 9 do not appear in the probes 10, allowing to know and control the flow of service connections that occur.

These communications are registered individually and are investigated in the national operator's equipment to detect the illegal entry point into the network, so that the way to detect the exact point varies depending on the equipment and technology used.

Also, by having sessions with known parameters injected into the network, you can quickly see the reliability of the information and take the appropriate measures in case it is not appropriate.
