Abstract

The method involves typing a single command by a user and billing a payer account (6), if a payer account identifier of the command is acknowledged in a payer account identifier database (32) and if a system management module (31) of a payer account billing system (3) detects authorization data associated to the identifier of a subscriber in the database. Data triggering a communication call, towards a destination number on a wireless telephony network, is sent to a mobile terminal, in case of billing authorization. Identification data of the account to be debited is sent to a billing unit. An independent claim is also included for an equipment for the selection of a payer account to bill for a transmitted telephonic call via a single command from a mobile terminal connected with a wireless telephony network, towards a recipient number.

Description

Method and equipment for selecting, from a mobile terminal, a

  The present invention relates to the field of telecommunications in a mobile radio network, and more particularly relates to a method and equipment for selecting a payer account of a telephone call, allowing a mode of selection. call by call of the account to debit.

  The current billing systems of customers used in consulting or service companies are based on the declaration of a customer code o before dialing from a fixed telephone, considered as the terminal of an enterprise PBX switch. These systems are unsuitable for billing calls from mobile terminals.

  When it comes to billing communications over a mobile terminal, current solutions can not manage different payment sources effectively. For example, a selection system on the terminal previously equipped with a specific software, to choose a payer of communications, offers only a limited selection of 2 accounts to load (at most).

  Other solutions exist, using billing data analyzed and then broken down after valuation of the tax tickets issued by the mobile switching central equipment MSC (Mobile Switching Center), according to various criteria that do not allow most of the time to manage a multitude of payer accounts.

  All these solutions have major disadvantages such as the requirement for the user to have a specialized terminal equipped with the specific software (incompatibility of the solution with all the terminals of the park) and the impossibility of managing multiple accounts of payers for a given number.

  Furthermore, existing radio networks do not have a feature that can easily manage the selection of accounts to debit.

  There is therefore a need to provide a billing service for directly debiting a third party account, call by call, from an ordinary mobile terminal (for example GSM type) to prevent users waiting for a billing which is the most of the time monthly.

  The present invention therefore aims to eliminate one or more of the disadvantages of the prior art by defining a method for placing a simple command to make a call-by-call selection of the payer account to be debited from a mobile terminal, without requiring any specific software on this terminal.

  Another object of the present invention is to propose a mode of support for all the calls of a mobile terminal by a paying account, activated by default during one or more determined time slots, this support being deactivated the rest of the time.

  To this end, the invention relates to a method of selecting a payer account of a telephone call from a mobile terminal in connection with a radiotelephone network, characterized in that it comprises a user input step, on an interface for entering and displaying the mobile terminal, a single order including a billing request by a payer account, an identifier of a payer account and a recipient number to be called, the method then comprising: a step validation of the order and sending from the mobile terminal data including representative of the billing request and the identifier of the payer account; an interpretation step using network-related decoding and switching means for interpreting data representative of the billing request from the data sent, and then routing data including the payer account identifier to a billing system of the billing account; paying accounts, a subscriber identifier corresponding to the mobile terminal being also transmitted by these means to the system; an identification step performed by a system management module to authorize billing on a payer account, only if the identifier of this payer account is recognized in a database of the system storing creditor account identifiers and if the management module detects authorization data associated with the subscriber identifier in the database; and - in the case of authorization, a step of sending to the mobile terminal the data making it possible to trigger on said network a call for communication towards the destination number, as well as a step of sending to billing means of the network of credentials of the payer account to debit.

  Unlike conventional polling commands addressed exclusively to the network, the single command used in the method of the invention allows the interrogation of a billing system. The network has new ways to interpret the single command, both to select the payer account and to route the call number to trigger a call.

  The invention thus makes it possible to effectively remedy the drawbacks of the prior art by proposing command recognition in the operator's network, ensuring full compatibility with the existing fleet of mobile terminals. The method of selecting a payer account leaves the possibility of choosing, for each new call, the payer of the communication to be issued, the latter having previously agreed.

  According to another particularity, the input step comprises an entry of a first control field of two alphanumeric characters preceded by ** and followed by *, intended to trigger the billing request 3o by a payer account.

  According to another particularity, the input step comprises - an entry of a first control field intended to trigger the billing request by a payer account; - after entering the first field, an entry of a first number assigned by the billing system to a paying account; and - after entering the first number, an entry of a second number representing the recipient number to be called.

  According to another particularity, the information entered during said input step is included in a command of type starting with a star pair ** and ending with a hash #, the command being validated o by pressing a key d. sending the mobile terminal interface.

  According to another particularity, the interpretation step uses at least one table of the network to interpret the type of command validated.

  According to another particularity, the identification step comprises, beforehand, generation by the management module of a billing authorization request ts including the identifier of the payer account and the subscriber identifier.

  According to another particularity, the method comprises a step of storing in the database, by the management module of the system, authorization data associated with each subscriber identifier, the authorization data including time parameters of authorization associated with each subscriber ID.

  According to another particularity, a step of deactivating the billing by said payer account is executed in response to an entry and validation of an order ## XX # +, where XX represent two alphanumeric characters.

  According to another particularity, the management module triggers, in response to the identification step, sending to the mobile terminal: - or data to trigger said network a call to the recipient number, if a billing on the paying account is allowed 3o, these data sent to the terminal including an acknowledgment message; - or refusal data to trigger a call on the network to the recipient number, ignoring the billing request.

  According to another particularity, the step of sending the identification data of the payer account to be debited to the billing means comprises a step of transmission by an MSC device, a tax ticket to an equipment supervision center. , information contained in tax receipts being then transmitted by said center to a system for discriminating calls to bill.

  The object of the invention is also to propose an equipment for selecting a payer account for a call, enabling a calling-by-call selection mode of the account to be debited from a mobile terminal.

  For this purpose, the invention relates to a selection device for a payer account to be billed for a telephone call transmitted via a single command from a mobile terminal in connection with a radiotelephone network to a destination number, characterized in that it includes: - a paying account billing system including a database for storing paying account identifiers and a management module for authorizing billing on a payroll account referenced in the database and detecting associated authorization data a subscriber identifier in the database; network-connected decoding and routing means for interpreting data representing a billing request from a payer account from among data sent over the network in a single command from a mobile terminal, and for routing said data of a payment account; query and a subscriber identifier corresponding to the mobile terminal to the system; the management module being arranged to allow billing of the call on a payer account, in response to the recognition of the corresponding identifier and the detection of authorization data associated with the subscriber identifier of the terminal in the database, the management module being further provided to send to the mobile terminal data for triggering on said network a call to the recipient number specified in the single command, and to send to the billing means of the network of credentials of the payer account to be debited from the database.

  According to another particularity, the equipment comprises interpretation means using at least one table of the network to interpret a type of command validated from a mobile terminal as a billing request from a paying account.

  According to another feature, the equipment comprises means of storing in the database authorization data associated with a subscriber identifier, the authorization data including authorization time parameters associated with each identifier of the subscriber identifier. subscriber.

  The present invention also aims to provide a mobile terminal is specially adapted to very simply place an order directly requesting the network, before a call, billing by a third party account.

  For this purpose, the invention relates to a mobile radio terminal for implementing the method according to the invention, comprising an input and display interface and communication means with a mobile radio network, characterized in that it comprises in storage means a selection software interface enabling a user to select a paying account from among a plurality of paying accounts displayed in a menu and a recipient number to be called and then to trigger a command, the software interface comprising selection validation means arranged to trigger the sending of the command from the mobile terminal to a mobile radio network, the software interface being arranged to insert a billing request by a payer account, an identifier of the payer account selected and the recipient number selected in a type command starting with a stars ire ** and ending with a sharp #.

  The invention, with its features and advantages, will emerge more clearly on reading the description given with reference to the accompanying drawings given by way of non-limiting examples in which: FIG. 1 schematically represents an embodiment of FIG. an equipment according to the invention, by means of which a mobile terminal can select an account to be debited; FIG. 2 represents a logic diagram of the steps of the method according to one embodiment of the invention.

  In the following, although the present invention more specifically describes embodiments using a mobile communication terminal in a radiotelephone network, the term mobile terminal should be understood to refer to any type of portable or transportable equipment having remote communication functions, regardless of the mode of transmission of information between correspondent 1s (transmission via a wired network, radio, shortwave or medium wave or a combination of these modes of transmission).

  In order to issue a call paid by a paying account (6), for example a business account or any other account of third parties having previously agreed, the owner of a mobile terminal (1) may, according to the invention , enter a specific prefix to require a billing service different from the ordinary billing resulting from the subscription conditions of the terminal user (1). The method according to the invention proposes a selection mode, for example call by call, of the account to be debited for the call of a correspondent.

  This account to be debited can be chosen on a case by case basis. In one embodiment of the invention, the signaling network specific to GSM networks, or similar network (CDMA), can decode such a prefix indicating that a selection operation of a third-party payer account is to be performed. . With reference to FIG. 1, a mobile terminal (1) equipped with input and display interface means, connected to the network (N), enables the user to enter a single command including a billing request by a user. Paying account (6). The command specifies for example, after the billing request by a payer account, an identifier of such a payer account (6) and the recipient number to call. The recipient's call may thus be billed by the specified account, and not in the usual manner in accordance with the conditions of subscription to the operator of the radiotelephone network. The process according to the invention makes it possible to dissociate more than one payment method by invoking, when entering the recipient number, the account (6) to be billed for the call of this number.

  The call request formulated from the terminal (1) notably involves the basic radio stations (BTS) associated in particular with the devices (20) necessary for the operation of the signaling network that supports the discrimination of the command type. requested by the applicant possessing the terminal (1), and the network (N) radiotelephone in charge of the routing of this order and the subscriber identifier of the applicant to a system (3) billing is accounts payers (6). This identifier can be, in a conventional manner, the 15-digit International Mobile Subscriber Identity (IMSI) number used to identify the subscriber of a mobile terminal (1).

  As illustrated in Figure 1, the base radio station (BTS) can be connected to a switching equipment (BSC) from one cell (C) to another of a GSM subscriber. The central switching device MSC (24) for mobile telephony connects the radio part of the network (N) to the terrestrial network, for example a network using Real-time Transfer Control Protocol (RTCP) type protocols.

  The equipment provided according to the invention for enabling the selection of the payer account (6) to be billed includes, as illustrated in FIG. 1, a paying account billing system (6) with a database ( 32) for storing creditor account identifiers (6) and a management module (31). This module (31) can consist of an application responsible for the formulation of the request and the management of the return codes 3o (authorization given to the requesting or refusing terminal) and provided for managing the database (32) containing the numbers third parties and IMSI subscriber identifiers allowed to use them.

  In a preferred embodiment of the invention, the management module (31) is arranged to accept or refuse the billing authorization on a payer account (6) referenced in the database (32), this module (31) ) detecting for it authorization data associated with a subscriber identifier in the database (32).

  As illustrated in FIG. 1, clecoding and switching means (20, 25) connected to the network (N) make it possible to interpret, among data sent (D1) on the network from the mobile terminal (1), data representative of a billing request from a payer account (6). They also make it possible to direct this request data, as well as a subscriber identifier corresponding to the mobile terminal (1), to the billing system (3).

  In one embodiment of the invention, the owner of the mobile terminal (1) enters a command by sequentially numbering the respective parts of the command, then validates this command by pressing a call sending key. The entry comprises an entry of a first control field of two alphanumeric characters, for example two numbers, preceded by two stars ** and followed by a star *. This first field is intended to trigger the request for billing by the payer account (6). After entering the first field, the user enters a first number assigned by the billing system (3) to the desired payer account (6). Then, after entering this first number, the user enters a second number representing the recipient number to call.

  The entry / numbering is carried out as indicated in

the following example:

  ** 27 * PQMCDU * OZABPQMCDU # + sending the call.

  In this example, the command ** 27 * represents the billing request of a third party, the first number PQMCDU the account number of the payer to be billed, referenced in the database (32), the sign * represents a separator, the last number represents the number to call and the last sign # closes the request. The information entered is therefore included in a command of type starting with a pair of stars ** and Io ending with a hash #, the command being validated by pressing a send key of the interface of the mobile terminal (1 ).

  By convention and according to the terminology of the GSM standard (Global System for Mobile Communications), commands of the type ** XX # + sending are interpreted by the signaling network according to a table specific to the network (N) of the operator, which indicates the type of operation to be performed according to the XX order code that is inserted. This is usually a command specific to the subscription data related to the services (call forwarding, number presentation, ...) available. The signaling network uses transfer means for transmitting said command to the nominal location register (20) also called HLR (Home Location Registrer). The transfer means include for example at least one routing switch (25) of the SSP (Service Switching Point) type used in intelligent telephone networks. These transfer means also comprise a network operator management system (N) having information on the accessibility of subscribers to specific services.

  In one embodiment of the invention, interpretation means are provided in the management system for using one or more tables of the network to interpret a type of command validated from a mobile terminal (1) as a billing request of a payer account (6). The decoding and switching means (20, 25), consisting in particular of the transfer means of the signaling network and the HLR recorder (20), thus ensure the interpretation of commands of the type * # XX # + sending. These commands make it possible to query the manager system, specific to a network operator (N), on the activation or deactivation state of the requested service in a specification table reporting service data for a plurality of subscribers.

  In an alternative embodiment of the present invention, this order formulation terminology may for example be used so that the user can know the account number, and possibly the wording of the account, the payer before making a call. For this purpose, the decoding and switching means (20, 25) interpret a given code XX as an information request on a payor account number (6) authorized for the calling party's terminal, and then convey data representative of this information request to the billing system (3). The management module (31) provides the requested information by extracting from the database (32) credentials of the payer account (6) associated with the identifier of the requesting subscriber.

  Commands of the type ## XX # + send can also serve to cancel the requested service, XX representing for example two alphanumeric characters. Thus, the user of the mobile terminal (1) can trigger a return to the initial state by disabling the use of a payer account (6). The mobile terminal (1) then goes back to a configuration that provides a conventional method of billing the call to the caller.

  The management module (31) is arranged to allow or refuse a billing of the call on the payer account (6) reported in the service request. In response to the recognition of the PQMCDU number or analogous information to identify this account and the detection of authorization data associated with the subscriber identifier of the terminal (1) in the database (32), the authorization is granted by the management module (31). The latter furthermore makes it possible to send acceptance data to the mobile terminal (1) in order to trigger on the network (N) a call towards the destination number. Meanwhile, the management module can also send to the billing means of the network (N) of the payer account identification data (6) to be debited from the database (32).

  It is thus understood that, if the identification elements of the order preceding the recipient number in the order entered by the applicant, correspond with the information contained in the database (32) of the billing system (3) of account of payor> o (6), the management module (31) can return to the signaling network an acknowledgment to the IMSI of the terminal (1). In one embodiment of the invention, this acknowledgment triggers the call transmission authorization to the requested number.

  Naturally, in the absence of correspondence of information or if the subscriber identifier is not recognized as an authorized IMSI identifier, the management module (31) does not trigger the sending to the mobile terminal (1) of data including the acknowledgment message, but simply transmits refusal data. This refusal data can trigger a call on the network (N) to the recipient number, ignoring the billing request. Alternatively, an error message lo may be returned to the mobile terminal (10) to signify the denial and cause the call to fail.

  If an agreement is given by the management module (31) linked to the database (32), the authorization is conveyed by the signaling network to the mobile terminal (10) to allow the launching of the call on the network (N). The billing data relating to the account to be debited are included in the tax receipt issued by the centralized device of the functional layer of the network (N). The sending by the module (31) to the billing means of the network of the identification data of the payer account (6) to be debited can thus include the transmission by the device MSC (24) of a tax receipt to a center (4) equipment supervision. The latter transfers the information contained by the tax receipts to the system (5) which is in charge of discriminating calls to bill. A RCP remote procedure call system (26) may be used to initiate the transmission of the tax receipt to the supervisory center (4).

  While the choice of the third party account to be loaded can advantageously be carried out call by call in the preferred embodiment of the invention, it is possible alternatively to determine time slots in which a payer account (6) is systematically used for each billed call. For this purpose, the equipment for selecting a 3o payer account (6) to be invoiced includes means for storing in the database (32) hourly authorization parameters associated with each subscriber identifier. The authorization data therefore include these authorization time parameters, to allow the use of the payer account only for calls started in a time slot provided by the time parameters. One can thus imagine that the calls of the terminal (1) are taken care of from 9h to 19h00 by the paying account (6) which can be the account (6) of his employer and that all the calls outside these time slots will be charged to the appellant.

  The selection equipment may also allow the owner of the terminal (1) to decide to initiate a personal call on the network while the billings are normally supported by a payer account (6) of a third party during this period. call schedule. This user can disable for this call, the mode of support of this communication by the employer. The transition from a third party support mode (6) to a conventional billing mode can be done by simple command ## XX # + sending. This code is intended to cancel a billing mode by paying account (6) and return to the conventional billing mode.

  In an equivalent variant embodiment, the information communicated in the single command can also be transmitted in a similar manner in the form of at least two successive commands (the second command being complementary to the first command).

  In an alternative embodiment, the manipulations necessary for the establishment of a communication on behalf of third parties (** 27 * ...) can be performed directly from a software interface to be installed on the mobile or the SIM card (Subscriber Identity Module). This interface comes for example from a SIMTOOLKIT Applet downloaded OTA ("Over The Air"). Such a software interface facilitates the entry of the billing request by a third party account, using menus and / or display elements (icons) equivalent for selection. For example, it proposes the last 10 third-party accounts solicited and / or stored. A label for each 3o accounts (the name of the client for a law firm for example) can appear on the screen of the mobile terminal (1) and the user can select the corresponding account using the navigation keys of the terminal (1) or navigational means. The software interface thus provides a choice to the user who has the ability to fetch the number to call in the SIM directory or that of the mobile terminal (1). The information to be communicated in the order remains naturally the same: billing request by a paying account, the payer account number and the recipient number.

  In one embodiment of the invention, it is understood that the user may have the choice of entering the command either via the interface or by composing directly the command ** 27 * PQMCDU * OZABPQMCDU # + sending of the call.

  The selection process according to the invention will now be described with reference to FIG. 2.

  The method comprises a step (51) of input by the user, on an interface of input and display of his mobile terminal (1), a 1s single command including the request for billing by a payer account (6) , the identifier of this payer account (6) and the recipient number. As soon as the user has finished typing, the step (52) for validating and sending the command makes it possible to transmit from the mobile terminal (1) data (D1), in particular, representative of the billing request and the billing request. payer account identifier (6). These data (D1) transmitted to the network are received by the decoding and switching means (20, 25) to be analyzed during an interpretation step (53). Data representative of the billing request are extracted and interpreted from the data sent (D1) and data extraction (D2) including the identifier of the payer account (6) are routed by the decoding and referral means (20, 25) to the payor billing system (3) (6).

  Among the data transmitted from the mobile terminal (1), an IMSI type subscriber identifier or equivalent is transmitted by the decoding and routing means (20, 25) to the billing system (3). The management module (31) executes an identification step (55) to possibly authorize a billing on a paying account (6). This module checks during this step (55) whether the identifier of the payer account (6) provided by the extraction data (D2) is recognized in the database (32) of the system (3) and detects data. of authorization associated with the subscriber identifier in this database (32). The identification step (55) may comprise prior to a generation by the module (31) of management of a billing authorization request including the identifier of the payer account (6) and the subscriber identifier .

  If authorized, the billing system (3) initiates a step (56) of sending to the mobile terminal (1) data for triggering on said network a call to the recipient number to establish a communication, and a step (57) of sending to billing means of the network of identification data of the payer account (6) to be debit. In case of refusal, a step (58) for sending refusal data is then performed by the system (3). This refusal data is, for example, used by the terminal to trigger a call on the network to the recipient number, ignoring the facolation request.

  The billing system management module (31) (3) stores the authorization data associated with the subscriber identifiers in the database (32) during a storage step (500). Updates of the authorization information are made in the database (32) by the management module (31).

  An example of application of the equipment according to the invention is the possibility offered to companies such as law firms to bill their customers for past mobile communications, whereas the current billing system of the law firms is based on the declaration of a customer code before dialing from a fixed telephone, considered as terminal of an enterprise PBX switch. The contribution of mobility while allowing to continue to bill precisely the accounts of third parties is an undeniable asset. One can also consider the common case of company lines entrusted to employees, for example to manage personal calls or spent outside working hours (combination of the time variant and preferred embodiment call by call). If, on the other hand, the employee is a member of an association and wishes that the calls relating to this activity be billed to the association's account (which will receive the detailed invoice for control), this also becomes possible. With a single number, several payers are possible.

  An advantageous application of the method according to the invention can also be mentioned; the case of a user of a Rechargeable Blocked Account type of formula or a Prepaid who, for lack of credit, can no longer make calls, but whose calls could then be supported by a third party ( parents for a child for example).

  One of the advantages of the invention is to propose a service easily accessible from a mobile terminal via a simple numbering. A request for authorization to use a paying account can be formulated by a simple prefix of a call number, the authorization being automatically provided or refused by the network according to the result of is the consultation of the base data containing account permissions for the requested throughput.

  It should be obvious to those skilled in the art that the present invention allows embodiments in many other specific forms without departing from the scope of the invention as claimed. Therefore, the present embodiments should be considered by way of illustration, but may be modified within the scope defined by the scope of the appended claims and the invention should not be limited to the details given above.
