Another list of telephone numbers in the server is associated to the former list of numbers. The latter list is transmitted to a user through short message service. A communication is established with the correspondent via the telephone number related to the correspondent from the server.

Description

CARRIER SELECTION SOLUTION FROM TELEPHONE

  MOBILE FOR PREFERENTIAL COMMUNICATIONS.

  The present invention relates to the field of mobile telecommunications.

  The present invention relates more particularly to a method for making a call from a mobile telephone without using its mobile operator to bill the call, using a carrier different from its mobile operator.

  The prior art already knows many solutions for establishing calls from a mobile phone.

  For example, the prior art knows the GSM standard and more particularly the specifications of ETSI and 3GPP defining the call conditions from a mobile system.

  The prior art also knows, by various patents such as US A 5438616 and US A 5710809, callback based methods in which the user establishes a first connection to a server, then breaks the call. The server calls back the caller, prompts him to dial his correspondent's number, then establishes the second call and connects the two parties.

  Such solutions, although proven, have several major drawbacks: 1. the user must number twice, 2. the time to establish the call is lengthened accordingly, 3. the service is only unprofitable. for short calls because it imposes a communication established between the server and the user, to allow him to dial then wait for the establishment of the second call, and 4. the server will not succeed in all cases to reach the corresponding connected to a mobile network, and may see its call frequently routed to the voice mail of the user operated by its mobile operator, giving rise to an unnecessary call billed to the service provider that will pass through in its tariffs, and resulting in a drop in quality noticeable by the user could not be recalled quickly.

  There are also other solutions which partly remedy these disadvantages, which gave rise in particular to patents WO 0000 22863A1, EP 00 989719A2 and WO 00007391A1, processes in which the user establishes a packet connection (and not by circuit ) using the data transfer services (such as GPRS), the short message service (such as SMS) or the USSD supplementary service to transmit to the server the contact details of the called party, and allow him to simultaneously establish the call to the caller and the caller's callback, providing both time savings and savings in the price of the service that the service provider can pass on to user rates.

  Such methods, although proven, nevertheless have several major disadvantages: 1. the user must dial twice, 2. the ergonomics from a mobile phone to establish a data connection or send a short message is often less user-friendly that to make a call often resulting in additional loss of time for the user, 3. these connections to the server to transmit the requested n are billable by the operator, 4. for customers traveling abroad , the user is doubly penalized, both on the high price of the message from abroad and on the additional cost billed by the original operator to forward the call to the user abroad and 5 In any case, the server will not be able to reach the correspondent attached to a mobile network, and may see his call frequently routed to the user's voicemail operated by his mobile operator, giving rise to an unnecessary call billed to the service provider that will pass on in its rates, and resulting in a drop in service quality perceptible by the user could not be recalled quickly.

  The prior art also knows solutions of assisted call back proposed by the network of an operator, such as described by the patents EP 0 1124394 A1 or US 0 5943397 in which it is the network of the operator which is subscribed the applicant or the requested party who, at the request of a third party, or after agreement of the applicant, takes the initiative to establish the two calls and the connection. These methods are not relevant to the present invention.

  There are also other voice communication solutions from a mobile system using the GPRS network, in which the user establishes a data connection (eg GPRS) of a sufficient rate, and uses a specific encoding and compression algorithm the speech available in his phone not to establish his circuit-mode telephone communication on the network of the operator of which he is the subscriber, and benefit from a packet transport solution, the pricing may be more favorable on from the local loop access to the transit network. But such solutions, still very expensive in terms of GPRS access, require very powerful programs of coding and compression of speech that do not know how to host the current phones and especially require a guaranteed bandwidth on the GPRS connection (the order of 30 Kbit / sec) that mobile operators do not yet know how to guarantee.

  The prior art also knows carrier selection solutions described in numerous patents, standardized by ETSI, and implemented in many countries at the initiative of the public authorities or the national regulatory authority. These mechanisms are based on three families of processes, the first two on the initiative of the user (either by dialing a short number, waiting for a tone, then dialing the number requested, or by dialing a prefix attached to the number of the called party), the last to the initiative of the local network whose user is the subscriber following pre-registration (function of selective routing of certain calls to a carrier, and not invoicing by the local operator of these calls to the user but billing wholesale traffic to the carrier). Such mechanisms, while relevant, have not been provided or implemented on mobile networks, and are characteristic of fixed telecommunication networks.

  The present invention intends to overcome the disadvantages of the prior art by allowing a user or his mobile terminal to simply pass a single call to reach his correspondent, without necessarily having to use the operator of which he is the subscriber to provide the the entire service or charge the customer the full price of the service.

  To do this, the present invention is of the above type and it concerns in its broadest sense a communication method on a mobile telecommunications network with selection of the carrier, comprising at least one server and a user provided with a device mobile telephony, characterized in that it comprises at least the steps of: E Registering at the server a first list comprising at least a preferential correspondent number in a database; Associate with said first list, a second list of telephone numbers of the server; Transmitting said second list to said user; Establishing a communication with said preferential correspondent via the call number of the server associated with said correspondent.

  Preferably, said step of transmitting the second list to the user is done by SMS.

  According to a first embodiment, the step of recording at the server of said first list is done by a telephone call to said server.

  According to a second embodiment, the step of recording at the server of said first list is done by a website.

  According to a third embodiment, the step of recording at the server of said first list is done by a WAP connection on CSD or GPRS Advantageously, the step of recording at the server of said first list is done by sending SMS to the server.

  Preferably, said step of registering at the server of said first list is at the mobile equipment of the user, in the SIM or the terminal.

  According to one embodiment, said recording step is preceded by a step of downloading a software component in the SIM or the terminal for automatic registration of the preferential numbers.

  Preferably, said step of updating the number lists in the server is done at the initiative of the terminal or the SIM by sending SMS.

  Advantageously, said step of updating the number lists in the server is done at the initiative of the terminal or the SIM by WAP connection to CSD or GPRS.

  According to a last variant, said step of updating the number lists in the server is done at the initiative of the terminal or the SIM by telephone call.

  According to one embodiment, said first list of preferential correspondent numbers and said second list of call numbers of the server are in bijective correspondence.

  According to another mode of implementation, a server call number corresponds to at least one preferred addressee associated with at least one user of the service.

  Preferably, the method further comprises a step of analyzing the calling number.

  Advantageously, said step of establishing the communication with a preferential address is performed from a line different from that of the user having recorded by means of a call number to the server uniquely assigned to a user. .

  According to one embodiment, said step of establishing communication with a preferred recipient is performed from a prepaid mobile phone line whose credit is exhausted, thanks to a callback of the client on its main line by the server.

  According to one variant, the server's call number is a public plan call number. According to another variant, the call number of the server is a combination of the public plan's call numbers and the applicant's subaddress. .

  Preferably, the server decides, after analysis of the calling line number and the number dialed by the user to the server, whether he must put the caller and the correspondent directly in relation, or if he must call back the caller before linking.

  The innovative nature of the process is that the holder of the mobile line can issue telephone calls through a third party service provider without being obliged to use the services of the mobile operator of which he is the subscriber. , by composing only one billable call.

  The invention will be better understood from the following description, given purely for explanatory purposes, of one embodiment of the invention, with reference to the appended FIGURE: FIG. 15 numbers in the database as well as the step of direct appeal to a preferred recipient.

  Illustrated in Figure 1, according to a preferred embodiment, the client first connects to the server 1.

  Once connected to the server, it composes the code * 1 and the system offers him to declare for example his ten favorite numbers.

  The server then asks him to type 1, then the client types the number and then validates with #. The server then restates the dialed number and requests a new validation by #.

  The procedure is then repeated for subsequent numbers.

  The server then stores these numbers in a database (2).

  At the end of the entry, the server informs the customer that he will receive the call codes corresponding to each preferential correspondent.

  The mode of sending the call codes is for example made by SMS short messages.

  The SMS is written for example as follows: The service thanks you for your confidence: to reach the 0607060708, dial 0123456771, to dial 0123456772, etc. You can change these numbers at any time by dialing 0123456770 then typing * 1, or through our website.

  In case of a call from the client to the server on a preconfigured number of a preferential correspondent, the server then directly establishes the connection and connects the calls, as shown in FIG.

  According to another embodiment, in case of a call from the client on a preconfigured number of a preferential correspondent, the server breaks the call, then establishes the call to the correspondent and calls back the user. Once the call back has been obtained for communication to the requested party, the server connects the two calls.

  According to a particularly advantageous embodiment, the numbers preconfigured to join the server or the preferential correspondents are assigned uniquely to a client, and he can establish a connection to the server from another fixed or mobile telephone line. The server will recognize the caller, and will call him back on his main line, and join the caller to connect the two calls.

  According to another embodiment, after downloading a component in the mobile system (in the SIM card or in the terminal), the preferential list registration step can be done directly on the mobile system of the user. . This then allows the user to avoid the calling step to the server (1). It can of course in the same way modify the numbers, add, or delete. This can be achieved for example through a special low-cost phone menu created at the user's mobile system level when downloading the component. At each update by the user of his favorite correspondents in his mobile system, a connection is established to the server by any appropriate means (GPRS, SMS, etc.) to update the client parameters in the server and the table correspondence between server access numbers and correspondent numbers.

  According to one variant, the numbers assigned by the server are not in bijective correspondence with the preferential numbers. Thus, a server number may correspond to 2 or more preferred recipients associated with 2 or more users of the service.

  For example, if two persons A and B subscribe to the service implementing the above method, the preferred recipient of A, and the preferred recipient of B can be associated with the same server number 0123456771.

  For this reason, the step of registering the numbers may be accompanied by a step of registering the calling line number of the user of the service.

  At the time of the call, the step of placing in communication by the server is then accompanied by a step of analyzing the calling number.

  If the calling number is hidden by the user, the server can deliver a message of deterrence (non-billable) type: Your number is hidden: to unmask your number, dial before the n of your correspondent prefix XYZT from a mobile line , and XYZT from a fixed line.

  In the case of the use of the service with pre-paid coupon, with allocation of call credit to a calling line, the server also performs a validation step of the code associated with the coupon.

  In the case of using the service with a pre-paid credit, with credit to a calling line, the server checks permanently that the available credit balance is sufficient to establish or continue a conversation, and if the credit is completed during communication, the server interrupts the communication after hearing alerts broadcast to the caller.

  According to a particularly advantageous variant, for a predefined client, the number of the call to the server associated with a predefined correspondent may be a combination of a call number in the public dialing plan and an ISDN subaddress such as defined in the ISDN standard at ETSI. Such a variant making it possible to restrict the number of call numbers of the public plan to be allocated to the service.

  According to another very advantageous variant, the call number uniquely assigned to a caller to enable him to call the server or a correspondent from another line than his usual line may be a combination of a telephone number in a telephone number. the public numbering plan and an ISDN subaddress as defined in the ISDN standard at ETSI. Such a variant making it possible to restrict the number of call numbers of the public plan to be allocated to the service. The invention is described in the foregoing by way of example. It is understood that the skilled person is able to realize different variants of the invention without departing from the scope of the patent.
