METHOD FOR PERFORMING INFORMATION TELEPHONE CALLS

The invention relates to téléphoné communication, in particular to methods for notification of the called subscriber in the communication networks, namely in the absence of the calîing party’s valid crédit account, and can be used in existing mobile télécommunications Systems, including GSM, 3GSM, 3G, CDMA, WCDMA, and others.

The widespread use of mobile communication is an undeniable evidence of its convenience to users and causes the ever-increasing need to expand services provided by mobile operators.

For example, of great importance in the implémentation of mobile communications is the ability to transfer a call from the callîng party to the called party.

As a rule, the need for such a service arises in standard situations, when the called party's phone is tumed off, is out of service or busy, for example, the subscriber answers another call.

However, in practice quite often the impossibilîty to establish a contact with the called subscriber is connected with the absence of a valid crédit account of the callîng subscriber, which can lead to the loss of an important call.

At présent, some methods are developed that prevent the loss of such calls by transferring them from the called subscriber, thanks to his notification of the held call, to the callîng subscriber. In such cases the burden of payment falls on the called party, which in this case acts as a callîng party.

It is known a method for announcement of a call from an insolvent callîng subscriber to transfer a call by dialîng a certain pre-determined set of digits and signs [1], According to provided information the diaied number is in the form of: *111* called subscriber’s phone number #ok. In this case the called subscriber receives an SMS with a request to call and the phone number for communication.

This method is inconvénient because the callîng subscriber must dial a new, often unfamiliar sequence of digits and signs that not everyone knows, and in critical situations of emergency call even knowing users cannot simply remember it.

In addition, this embodiment of call is valid only in the network of one offering it operator, which considerably limite the possibility of using the described method.

The closest by the technical essence to the claimed method is a method for managing the téléphoné communication, as set out in the Russian patent N 2361369 [2], X

According to the known method for the implémentation of calis in the mobile communication network each network subscriber is provided an opportunity to get network access for outgoing calls, regardless of the status of his/her account and accept the call and/or receive calling subscriber’s messages without the prepaid crédit account, at the same time the calling subscriber dials the phone number of the called subscriber, the operator of the calling subscriber détermines his solvency, for the called subscriber is created a notification about the missed call with the représentation of information about the calling subscriber.

In determining by the operator of the fact that the calling subscriber is a user who does not hâve a valid crédit account, it is send a cal! over the network to the operator serving the called subscriber. It is passed the call to the called subscriber. The unpaid outgoing calls past over the network are disconnect, after the predetermined number of rings, at the entrance of the called subscriber’s mobile phone. As stated in the patent, the used network is set up so that calls outgoing from a calling subscriber’s téléphoné are dîsconnected after one ring.

The system that implements this method represents a network configured with the possibility of getting network access for outgoing calls, regardless of the state of the subscriber’s account and receipt by the subscribers’ phones of calls and/or messages from calling subscribers. The call outgoing from a mobile phone passes through the operator of the calling subscriber, schematically shown by a base station, mobile communications switching center and relocation register, and goes directly to the operator of the called subscriber having a similar circuitry and associated with the mobile phone of his subscriber.

In accordance with the patented method and system over the network to the mobile phone of the called subscriber pass ail calls: paid and unpaid, the latter are automatically dîsconnected at the input ofthe calling subscriber’s phone, passing one ring. According to the invention, that is sufficient for a notification to appear in the phone about the missed call.

However, in the description of the invention there is no information on the action and, accordingly, the apparatus module in the proposed configuration of the network with which the network is dîsconnected at the input of the called subscriber’s mobile phone.

In reality, the hardware solution of the mobile communication network, providing for the disconnection of calls at the input of the called subscriber’s phone, is currently insuffïciently worked on. On the other hand, there may be a situation of technical failures in the network, as a resuit of which a connection is established in the passing call and the called subscriber answers. In this case, the burden of payment will be on the calling subscriber and he will receive a bond from his operator.

Thus, the expected resuit will not be achieved. q/

Ail this will considerably reduce the reliability of the method for managing the téléphoné communication described in the patent Ns> 2361369.

The problem, to be solved by the proposed invention, is to create a reliable and userfriendly method for performing information téléphoné calls, realizing the possibility for the calling subscriber, in the absence of a valid crédit account to pay for a call, to inform the called subscriber of the calling attempt in real time in various mobile télécommunication Systems.

The problem is solved by the fact that the in the method for performing information téléphoné calls, performed in a mobile communication network, in which each subscriber of the network is provided with an opportunity to get network access for outgoing calls, regardless of the status of his/her account, and to accept the call and/or receive the calling subscriber’s messages without the pre-paid crédit account, the calling subscriber dials the phone number of the called subscriber, the operator of the calling subscriber détermines his solvency, a notification about the missed call is created for the called subscriber, providing information about the calling subscriber, upon initiation of a call by the calling subscriber, who does not hâve a valid crédit account, for its transmission to the called subscriber the outgoing call is directed through the operator serving the calling subscriber to a forwarding and controlling server and at its command disconnects the calling subscriber, the forwarding and controlling server processes the obtained information and forms a transit call, by the transit call through the operator serving the calling subscriber is transferred an outgoing call to the operator’s network serving the called subscriber as an information call, notifying of the missed call, the information call is disconnected after its receipt by the called subscriber.

At the same time, upon disconnection the operator servicing the calling subscriber sends him a notification of the absence of the valid crédit account.

The resuit, obtained by means of the claimed method, consiste in increasing the reliability and ease of communication between subscribers in an irregular situation, namely upon insolvency of the calling subscriber.

This resuit is ensured by the fact that the proposed method, unlike the prototype, is based on a different ideological approach to the implémentation of the communication. According to the known method over the network to the phone of the called subscriber pass both the paid and unpaid call, whereas in the proposed invention the paid call passes over the network, and the unpaid call is disconnected. At the same time an information call is sent to the called subscriber as a signal to feedback.

In the proposed method are elimînated the random connections of the calling and called subscribers for unpaid calls, as such a call from the operator enters the forwarding and controliing server. Introduced into the architecture of the télécommunications network the new node - server - monitors and routes both incoming and outgoing calls.

Over the network from the forwarding and control server through one operator to another is directed the transit call formed in the server, transmitting to the called subscriber an outgoing call as an information one, containing the data of the calling subscriber, at the same time the calling subscriber is disconnected.

As a resuit, the information call incoming to the called subscriber cannot connect him with the calling subscriber, and, therefore, are excluded the conversations that must be paid by the insolvent network user. The called subscriber, receiving the information about calling him person calls back, thus taking on the burden of payment.

The implémentation of this method will allow not only reliably connect subscribers in a created irregular situation, but also establish a connection using the familiar operation of dialing the desired number.

Thus, the proposed method for performing information téléphoné calls is reliable and convenient in operation, which ultimately improves the quality of mobile communication services.

Summary of the invention is explained in the foliowing description and drawings.

The claimed method is implemented as follows.

Each network subscriber ïs provided with an opportunity to get network access for outgoing calls, regardless of the status of his account and accept the call and/or receive the calling subscriber’s messages without the prepaid crédit account. The calling subscriber dials the phone number of the called subscriber; the operator of the calling subscriber détermines his solvency; upon initiation of a call by the calling subscriber who does not hâve a valid crédit account, for its transmission to the called subscriber the outgoing call is directed through the operator serving the calling subscriber to a forwarding and controliing server and at its command disconnects the calling subscriber; the forwarding and controliing server processes the information and forms a transit call; by the transit call through the operator serving the calling subscriber is transferred an outgoing call to the network operator serving the called subscriber as an information call notifying of the missed call; for the calling subscriber is created a notification of the missed call, providing information about the calling subscriber; the information call is disconnected after its receipt by the called party.

Upon disconnection the operator servicing the calling subscriber sends him a notification of the absence of the valid crédit account.

The above steps of the method are carried out by means of a hardware support.

The drawing schematically illustrâtes the téléphoné network, through which the proposed method is carried out.

The mobile phone 1 of the calling subscriber A maintains contact with the switch 2 of the operator serving the given subscriber. The switch 2 is made with the possibility to redirect a call coming from the subscriber A. The switch 2 is connected to a service forwarding and controlling server 3, made with the possibility of receiving the outgoing call of the subscriber A, processing the received information and forming the transit call signal. The switch 2 is also connected to the switch 4 of the operator serving the called subscriber B, having a mobile phone 5. The switch 4 is made with the possibility of receiving and transferring calls to the mobile phone 5.

In the process of implémentation of this method for performing information téléphoné calls subscriber A the crédit account of which is not valid and outgoing calls are restricted, from his mobile phone makes a call, entering the switch 2. The switch 2 receives the call of subscriber A and vérifiés his solvency. In the case of establishing the fact of insolvency of the subscriber A the switch 2 redirects the outgoing call to the forwarding and controlling server 3. The server 3 processes the received information, generates a command for the switch 2 to disconnect the mobile phone 1 and forms a transit call, which it sends to the switch 2. The switch 2 détermines the received signal as a transit call, serving as an information call, and transfers it to the switch 4 in the network of the called subscriber B. The server 3 controls the passage of the information call and disconnects it after its entry into the mobile phone 5. At the same time the called subscriber B receives a message about the missed call, providing details of the calling subscriber A.

The communication between the switch 2 and the server 3 can be arranged both through a protocol such as IN (Intelligent Network) and a protocol ISUP (Integrated Services User Part).

The described method, impiemented by the scheme shown in the drawing, refers to a situation when subscriber A and subscriber B are served by different operators.

In the case where subscribers A and B are served by one operator, the transit call goes directly to the subscriber B.

In the process of implémentation of the method are used conventional for mobile communication, widely described in the spécial literature and well known to those skilled in the art hardware and software tools.

Exemplary embodiment

The proposed method has been used in the process of experimental communication between two subscribers A and B, the first of which had no money on the crédit account. Both subscribers were the owners of mobile phones Nokia X3.

In the formation of a télécommunication network, implementing this method, as a switch serving the subscriber A and a switch serving the subscriber B, has been used a switch of the type MSC (Mobile Service Switching Center) with a node GMSSC (Gateway Mobile Service Switching Center) included therein, executed on the module Ericsson AXE10. At the same time GMSSC is the gateway mobile service switching center and configures the routing of téléphoné connections.

As a forwarding and control server was used the Beep SCS server (Service Controlling Server) graded Giness BSCS vl .4.

Initiated by the subscriber A the call of subscriber B enters the MSC, which checks the type of subscriber and requests through the protocol INAP (Intelligent Network Application Protocol) in the IN SCP (Service Control Point) an authorization for the service. In the absence of the valid crédit account of the subscriber A SCP rejects the call, sending the corresponding disconnection code. By using the MSC/SSF service switching function, MSC redirects the call initial address message (ISUP_IAM) - through GMSSC in Beep SCS (Service Controlling Server).

In this server from the message is extracted the phone numbers of the calling and called subscribers, and the call is disconnected, using a pre-configured code. Call processîng is complété and the GMSSC at the Beep SCS command disconnects the call received from the MSC/SSF, and the MSC/SSF, in turn, in accordance with the service switching function disconnects the calling subscriber A.

Then Beep SCS forms a call in accordance with the initial address message, using the numbers of previousiy registered calling and called subscribers. Thus, in the network is created an outgoing call, formed in Beep SCS (service forwarding and controlling server) and performing the function of information call. Beep SCS sends this call through the GMSC of MSC switch, serving the calling subscriber A, by appointment, in accordance with the phone number of subscriber B, to the MSC switch, serving the called subscriber B.

In turn, this switch through the GMSC sends to Beep SCS (ISUP ACM) or (ISUP_CPG) a message on the receipt by subscriber B téléphoné of the complété number of subscriber A. In response to the received message Beep SCS instantly disconnects the information call, so that the called subscriber receives only a short call and an information missed call message on the mobile phone screen.

As seen from the process for performing in a mobile network an information téléphoné call minutely described in the exemplary embodiment, in the forwarding and controlling server the outgoing call ends and the information call is formed. pÇ

The direct communication between the subscriber A and subscriber B is absent and consequently excluded even the casual possibility of conversation at the expense of the insolvent calling subscriber, which confirms the solution in the invention of the undertaken task. c/
