Method for operating a telecommunication system and telecommunication arrangement

## Abstract

The invention relates to a method for operating a telecommunication system, including in particular a mobile radio network (PLMN), to provide a service and to obtain information.

## Background
DESCRIPTION
The invention relates to a method for operating a telecommunications system, including in particular a mobile radio network, to provide a service and to obtain information, as well as an arrangement to implement this method.
The dramatic development of the technology and infrastructure underlying mobile radio equipment in recent years has caused mobile communication to become a characteristic element of daily life in the industrialized countries. Mobile telephones have now been established far beyond the realm of professional use, as a means of communication for the entire population from juveniles to pensioners. The users of mobile phones are thus largely representative of the population in industrialized countries as a whole.
One result is that information about the users of mobile phones is extremely valuable, for the manufacturers, retailers and servicers of consumer goods as well as for governmental and social agencies etc.
In addition, in view of the high production and hence purchasing costs, everyone involved in mobile radio systems needs to ensure that the mobile phone is not only employed as primarily intended, as a means for bilateral transfer of information for the user's professional and private purposes, but also becomes more useful by the provision of extra services. Towards this end, games are incorporated into the mobile phone, and information channels and service offers are provided by the network operators.
Linking of the mobile radio network to the internet has already been introduced—at present on the basis of the WAP (Wireless Application Protocol) and employing the simplified data communication language WML (Wireless Markup Language)—and in the near future will open up a great number of new possibilities and further increase the acceptance and utilization of mobile radio technology on one hand, and of the internet on the other hand.
The German patent DE 693 09 682 discloses a hotel communication facility with a PABX coupling network, which is capable of responding to a call originating in a guest room so as to deliver automatically information requested by the caller, or to provide another service. The operating procedure of this telecommunications installation comprises the storage of a plurality of terminal-device call numbers belonging to the system and the generation of primary and secondary (response) messages as well as evaluation of the primary message, which in this case originates from the terminals in the guest rooms. As the end result of working through a menu, a particular item of information is conveyed to the terminal from which the primary message was sent.
The patent DE 198 33 218 A1 describes a telephone game system, one feature of which is that the participants are counted. In connection with this counting, an identification is provided so that when the total calls made by a given participant reaches a prespecified number, that person can be identified as a winner of the game and notified accordingly. In this procedure, again, there are primary and, in response thereto, secondary messages, and depending on the result of evaluating the primary message transmission of a particular secondary message (i.e., notification of winning) can be initiated.
The patent U.S. Pat. No. 4,899,369 discloses a so-called audiotex service in which the items on offer are presented in a display resembling a radio station finder. By pressing particular keys on a telephone keyboard, the user can set memory markers and thus call up a selection of the information available. Here, too, a primary message is sent out by the user's terminal and in response, following evaluation of the primary message, a secondary message is produced and sent out by the system processor.
The patent DE 198 19 582 A1 presents a teaching about the location-dependent provision of services within a mobile radio network, in particular the location-dependent charges imposed or the performance of route- or region-related tasks. By evaluating information regarding the location of the participant, from a service plan that describes the location dependence of the services provided, a current service profile applicable to the participant is derived. From this there can be derived a message to be transmitted to the participant.
In this context, it is the objective of the invention to disclose a method for operating a telecommunications system, including in particular a mobile radio network, with which in an ingenious linkage that ensures a high degree of user acceptance an attractive service is offered, while on the other hand information can be collected about the person making use of this offer. A further objective of the invention is to disclose an arrangement suitable for implementing this method.
This objective is achieved with respect to its methodological aspect by a method with the characteristics given in Claim 1 and with respect to the apparatus by an arrangement with the characteristics given in Claim 13.
The invention includes the essential idea that in a multi-stage sequence of reaction and response steps, users of telecommunications terminals (in particular mobile telephones) are presented with a specific set of in particular recreation-oriented services, and in case of a positive response the recreation-oriented service is immediately provided to the user by way of his terminal, during which process particular items of information are obtained and stored. This information comprises in particular the (verified) user call number, the geographic region in which the user is located, and where appropriate information about the individual, his leisure interests, his requirements regarding goods and services, etc. There are many possible ways of accomplishing this, depending on the nature of the services (forms of recreation) on offer and the kinds of information transmitted in this connection. The provider using the proposed system can therefore satisfy the information requirements of customers in a differentiated manner, given that the method is suitably implemented. Moreover, advertisements can be incorporated into the transmitted information, which further enhance the economical value of the proposed invention.


In a first preferred embodiment, which can fundamentally be implemented in cooperation with network operators, as a first call-number database at least one home location register or a visitor location register of a cellular mobile radio network can be used. In this variant, therefore, the method starts with an already verified quantity of user call numbers. As an alternative—without making use of the information base of a network operator—the method can start on the basis of arbitrarily synthesized numbers, or prespecified ranges of call numbers can be “scanned out”.
For application with a mobile radio network, information regarding the current location of the user, based on the position of his terminal, can be obtained from his allocated place in the visitor location register of a special mobile switchboard or else from the connection status with respect to a special base station of the network. It is known that the dynamic cell structure of mobile radio networks allows a specific user to be located. Here again, however, an appropriate implementation of the method is possible only in collaboration with the network operator, who has the relevant information at his disposal and, where its use is concerned, is subject to both legal stipulations and rules anchored in the system standard. When the method is applied in a public land-based network, spatial information can relatively easily be generated on the basis of the geographical reference encoded by the telephone number.
The messages exchanged within the scope of the method can be transmitted in speech or text form—the latter according to the permitted standards, for example SMS (Short Message Service) and WAP (Wireless Application Protocol) in the GSM mobile network. The choice of a specific format will depend on the nature of the service on offer and the target group, but also on the further technical development with respect to the transmission and display of text messages.
In an embodiment of the method that comprises more than two stages, in particular the secondary messages—in addition to the primary messages—contain requests for a response, and in the server means are provided for evaluating the response message thus obtained and for storing the results of the evaluation.
In a preferred design of the method the recreational service being offered is a game or quiz or a service to pave the way for relationships between individual users of the telecommunications system (forming interest groups, making new acquaintances, etc.). Here the primary message gives the basic information and inquires whether the user being addressed is willing to participate. With the very first response message the service operator receives valuable information consisting at least in the verification of a previously arbitrarily generated telephone number and/or information about the location of the person involved, as well as in the fact that this individual is interested in the specified offer. Subsequently one or more secondary messages are used to provide the rules for the game or information as to its progress and—given a suitable internal structure of the game or knowledge contest, or of the criteria for initiating personal relationships—to derive additional information from the messages received in response and store it in the database for evaluation results.
In an advantageous design of the method this process generates individual user profiles, which on one hand, in the case of a service for creating personal relationships, are used to implement this service, and on the other hand represent valuable information for commercial clients of the service provider.
In an especially advantageous implementation of the method the database for evaluation results is used to filter the secondary messages in dependence on the items of information received along with the response messages. The progress of the game or contest or the initiation of relationships is thereby made dependent on the current status of the information in each case.
In another preferred embodiment the secondary messages—at least in some stages of the method—are produced by employing memory contents of the database for evaluation results. This also enables cross-connections between individual memory regions to be produced, such that for example—naturally after the affected person has presented an appropriate declaration of agreement—telephone numbers of unfamiliar subscribers to the telecommunications system are given to a participant in the game. On this basis it is also possible to organise partner games under the direction of the service provider, who also monitors the results and finally determines the ranking of the participants and assigns the prizes.
An arrangement for implementing the proposed method is distinguished in particular by the presence of a first and a second call-number database as well as a database for evaluation results, such that the second number database and the evaluation database accumulate the user-related information acquired as the execution of the method proceeds. A primary- and a secondary-message memory—the latter of which can store the secondary-messages in a hierarchically stacked arrangement—constitute the system-side database employed as the method proceeds, and a progress-control unit incorporated into the server as well as one or more server terminals are used to implement the method. The term “server terminal” should be understood, depending on the specific design of the arrangement, to mean a telecommunications terminal device or a data-communication terminal or a data-communication interface.
In an arrangement constructed for an especially rational implementation of the method, a primary-message synthesis unit and/or a secondary-message synthesis unit is/are provided to automatically or semiautomatically synthesise the speech and text of the messages on the basis of information either programmed in or read out from a database. It is of course also possible to implement the method within the organisational framework of a call centre, in which case each of the agents makes use of the information stored in the message memories and the call-number databases.
Depending on the particular form taken by the method, the relevant databases also include a database for the rules of the game or for the answers to questions in a knowledge contest, etc. It has been pointed out above that in an advantageous embodiment of the method the database for evaluation results and the second call-number database are connected to the secondary-message synthesis unit, or can be accessed by an agent in the call centre in case the method is being carried out by a person.
An efficient means of implementing the method is to send out, at least phase-wise, a plurality of messages in parallel, in particular by means of the cell broadcast method. On this basis it is also possible to play games in which it is a matter of the quickness of the participants' responses or of concluding the game as a whole as rapidly as possible.
Other advantages and useful features of the invention will be evident in the subordinate claims and in the following description of a preferred exemplary embodiment of the invention with reference to the figure. The figure is a schematic drawing to show an arrangement for implementing the method by way of the Internet and, connected thereto, a GSM mobile radio network PLMN.
The structure of the mobile radio network PLMN is known per se and need not be explained in detail here. Mobile stations (mobile phones) MS are linked within a dynamic cell structure, each being connected by way of a base station BTS/BSC to a mobile switching centre MSC. To the mobile switching centre MSC are assigned a plurality of databases; those sketched in the figure are the equipment identity register EIR, the authentication centre AUC, the home location register HLR and the visitor location register VLR.
The mobile switching centre MSC is connected to other mobile radio networks PLMN—also at an international scale—by way of an international switching centre ISC. The mobile switching centre MSC also communicates, by way of a first gateway mobile switching centre GMSC, with the public switched telephone network PSTN or an ISDN telephone network ISDN, and by way of a second gateway mobile switching centre GMSC it is linked to the system belonging to the provider of a service in the framework of the present invention, as described below in-greater detail.
The service provider operates a server S, which by way of a server terminal SS—for example, a data interface of suitable capacity—is connected to the gateway mobile switching centre GMSC of the mobile radio network PLMN. The server S comprises a controller SC, by way of which the execution of the method proceeds.
To the server S is assigned a first call-number database CNDB1, which obtains its supply of data from the home location register and the visitor location register belonging to the mobile switching centre MSC. The server S also has access to a second call-number database CNDB2, the data content of which is gradually built up as the method is carried out. In a primary message store PMS is deposited a primary message or set of primary messages, which is/are generated on the basis of content prespecified in a primary-message synthesis unit PMG.
Also associated with the server S is a secondary-message store SMS, in which individually addressable memory regions contain a plurality of secondary messages that have been generated by a secondary-message synthesis unit SMG. In a special embodiment, in which the method is employed for the playing of a game, generation of the secondary messages by the secondary-message synthesis unit involves input of the game-rule data content of a game-rule database GDB, which is drawn in dashed outline to indicate that it is optionally provided.
On the output side the server S is connected to an evaluation unit EU to evaluate the response messages received by way of the server terminal SS, the output of which is connected to an evaluation-result database ERDB. This is accessible from outside—as symbolized by an arrow pointing outward—according to certain rules established with the service provider. The evaluation unit EU is additionally connected to an input of the secondary-message synthesis unit SMG, so that the evaluation results can be incorporated into the generation of secondary messages.
The way in which the illustrated arrangement functions will be evident from the above general discussion of the execution of the method.
The implementation of the invention is not restricted to the arrangement presented here as an example or to the method described and applications cited above, but is equally possible in a large number of modifications that are within the competence of a person skilled in the art.
