Definitions

  • the invention generally relates to the operation of a mobile radio network, and more particularly to a method and an arrangement for using certain information acquired during the registration of a mobile communication terminal at an exchange, in particular for generating traffic forecasts.
  • the detected data comprise at least one numerical identifier related to the person of the customer as well as the time and place of the registration at the exchange.
  • Aggregator receives certain data. To avoid movements and short-term stops, e.g. At service areas, it is important to be able to relate the location and time information as to when a communication terminal used in such a prediction method is located, at least over a certain period of time, to further location and time information via the same communication terminal can. It must therefore be ensured that information of the type "X is at Y2 o'clock at location Z2" can be related to information of the type "X is at Y1 o'clock at location Z1". On the other hand, it should be ensured from data protection law that the information where X has been when, are not easily accessible and in particular do not reach a company concerned with the preparation of traffic forecasts.
  • the document US2003 / 006983 describes the identification of mobile users using an encrypted identifier and changing the scheme to encrypt time to time.
  • the document DE10334140 describes the aspect of anonymous traffic data analysis.
  • the reference to the person of the customer identifier is replaced by a the mobile network operator or possibly an aggregator known assignment table by another identifier that the customer against. seemingly anonymous to the user, but at the same time makes it possible to relate the location and time information to other location and time information of the same customer.
  • the customer data is actually not anonymized, but it is assigned to each customer only a pseudonym, which can be easily and quickly determined by means of the assignment table, the actual customer.
  • the invention has for its object to provide a method and an arrangement of the type mentioned above, which make it possible to provide a user in particular for the preparation of traffic forecasts forwarded data of a customer of a mobile network operator on the one hand with an identifier that allows them, at least within on the other hand, but to ensure that the user from the identifier can not or at least not without significant effort on the identity of the customer inferring.
  • the object is achieved in terms of a method for the use of certain in the registration of a mobile communication terminal in an exchange detected information in particular for the preparation of traffic forecasts of a method with the features of claim 1 and with respect to a corresponding arrangement of an arrangement with the features of claim 13.
  • the respective subclaims relate to advantageous embodiments and implementation forms.
  • the invention is based on the idea of providing the data forwarded to a user with a unique identifier (a so-called identifier) which makes it possible to correlate it, at least within a certain period of time, to further data from the same customer of the mobile network operator
  • Function value of a one-way function is used as an identifier, so that the user from the identifier can not or at least not without substantial effort on the identity of the customer can infer.
  • the detected data comprise at least one numerical identifier related to the person of the customer as well as the time and place of the registration at the exchange.
  • VLR Visitor Location Register
  • the arrangement shown comprises a mobile services switching center MSC, which is associated with a database referred to in this application as a visitor location register VLR.
  • VLR Visit Location Register
  • a mobile communication terminal registers with the switching center MSC, which usually takes place automatically when it enters the reception area of the switching center
  • the visitor location register usually inquires with a further database, the so-called Home Location Register (HLR), certain data that is relevant for the Establishing a connection to and from the communication terminal are necessary and stores them temporarily.
  • HLR Home Location Register
  • the exact procedure of this procedure is usually defined in the standard specifications of the respective network.
  • VLR and HLR may be one and the same database in special cases.
  • FIG. 1 shown communication terminal MS, which may be, for example, a mobile phone, a "PDA" (Personal Digital Assistant) with mobile phone function or a built-in car phone, is owned by a customer of a mobile operator.
  • a subscriber identification module is arranged in the form of a SIM card SIM, wherein the SIM card is provided to the customer by the mobile service provider.
  • At least one subscriber identification number is stored in the SIM card.
  • IMSI International Mobile Subscriber Identity
  • MSISDN Mobile Subscriber ISDN Number
  • Each call number is assigned a specific subscriber profile in a manner known per se and therefore not further described here, wherein the subscriber profile of the customer considered here contains the information that certain data to a data-using unit USER, usually a complex data center, below briefly called users, for example, may be passed to the preparation of traffic forecasts.
  • the communication terminal MS logs on to a known, not shown here so-called base station subsystem (BSS) at the exchange MSC.
  • BSS base station subsystem
  • the exchange is handed over the IMSI.
  • step St 2 part of the transferred IMSI, namely the MSIN, is authenticated in the visitor location register VLR. If the visitor location register VLR finds a corresponding entry after the data comparison with the home location register HLR to the MSIN, it reports back to the switching center MSC in step St 3 about which service authorizations the user has or has subscribed to, so that then MSC the corresponding services can be started.
  • the above-mentioned fact that the customer has authorized the mobile network operator to transfer certain data to a user USER e.g. To pass on to the production of traffic forecasts, can be treated in a so-called intelligent network as a service or trigger a particular service.
  • the switching center MSC starts a dialog with a service center SCP in method step St 4 and transfers a data packet which consists of at least one numerical identifier related to the person of the customer as well as the time and place of the registration at the exchange.
  • a service center SCP in method step St 4 and transfers a data packet which consists of at least one numerical identifier related to the person of the customer as well as the time and place of the registration at the exchange.
  • the subscriber identification number or a terminal-specific identification number, the so-called IMEI are used as the personal identifier.
  • the one-way function used is a so-called. Strong, but at least a so-called. Weak one-way function, a strong eigenfunction by definition easy to calculate and difficult to invert, a weak one-way function is easy to calculate and something is difficult to invert.
  • the one-way function is a one-way drop door function.
  • this calculation of the function value does not have to take place in a service center or a suitable other location, eg in the MSC itself, on the part of the mobile network operator, but can, for example, an aggregator (see Fig. 2 ) to be transmitted by the mobile network operator, the data to be used, including the reference to the person of the customer identifier.
  • the service center in the exemplary embodiment shown forwards the data to be used, including the function value, which is assigned as the identifier to the data to be used, in particular the time and place of the registration at the exchange, but without the identifier to the data-using unit USER on.
  • Aggregator AGG is provided, which in this embodiment has the task of calculating the function value and the forwarding of the data to the user.
  • several aggregators can be provided, in which case those aggregators which forward data to the same user must calculate the function value at least within certain time windows in the same way in order to generate the same identifier and thereby ensure that the user identifies as originating from a mobile subscriber can (without, of course, get any clues about the identity of the mobile subscriber).
  • data transmitted after such a change can then no longer be assigned to data originating from the same customer on the part of the user, which, however, is unproblematic in the generation of traffic forecasts if the change takes place at times of weak traffic volume.
  • the switching center MSC If the switching center MSC has passed the data packet described above in method step St 4 of the service center SCP, it forwards it to the aggregator AGG in step St 5, whereby it can of course also be provided that the switching center communicates directly with the aggregator.
  • the service center SCP or the aggregator AGG evaluates the data to be used before forwarding to the USER using unit, if and, if so, with which speed and / or in which direction the mobile subscriber moves. To avoid unnecessary information transmission can then be further advantageous that the data to be used are forwarded to the using unit only when it is determined in the evaluation that the mobile subscriber is moving or that a previously detected movement has ended.
  • the one-way function and / or an additional key used with the one-way function and / or the numbers optionally added to the identifier according to predetermined criteria are changed at regular or irregular intervals.
  • service centers can be provided, which are addressed by the MSC before or after the service center SCP to perform more services.
  • the invention also enables a new business concept according to which it is possible for a mobile service provider to offer a customer an additional service with regard to traffic management and congestion avoidance.
  • This concept is hereby expressly designated as belonging to the invention and claimed to be eligible for protection in those countries whose national law permits this in principle.
