Definitions

  • the invention relates to a method for disseminating service information, a system and a service information center.
  • Service information from a service information provider that is transmitted via a radio network is usually only of regional importance.
  • Traffic information from a traffic information provider is generally only of importance for road users in a limited spatial area.
  • Traffic jam reports are, for example, on the road on which the traffic jam occurs, in the direction of the traffic jam propagation, and on access roads at a distance from which it can be expected that a road user located there can move to the end of the traffic jam in a certain time, for example two hours, significant.
  • Information about fog or black ice is also only of regional importance, namely where fog or black ice occurs. Therefore, regionally individualized information of a road user using service information with only the information that is important to him is desirable. However, individual identification of all road users for individual notification with service information that is important for them is too complex.
  • the object of the present invention is to create a method which enables a simple and effective notification of service information users, in particular road users, with service information locally relevant to them, in particular traffic information.
  • service information provider who provides the information in a service information center
  • radio network used to disseminate the information with the appropriate infrastructure and the associated control computers or control centers, since information providers and Communication providers can be different technical or organizational units.
  • Service information in the sense of claim 1 can in particular be traffic information. However, with a method according to claim 1, other only regionally important service information can also be transmitted to service information users.
  • the service information is distributed further to the service information user, in particular by radio via a mobile radio network to the mobile radio terminal of the service information user.
  • the service information center also transmits location information to a radio network center, which location information specifies the spatial area in which base stations of radio cells of the radio network are intended to distribute certain service information in each case.
  • the region of the radio network in which one or more new or changed service information is to be distributed by sending or one or more specific previously deleted information that has been sent should no longer be distributed, in that a specific group or groups of Radio cells in the region are prompted by the name of the group or groups to send a current page.
  • the radio network center and the service information center for example, define identical or definable which group designation contains which group of radio cells.
  • the method according to the invention enables the very inexpensive
  • a radio network can be the radio network of a single provider or a combination of radio networks of several providers, such as C, D1, D2, E1, E2 networks.
  • This method efficiently simplifies the dissemination of service information by a special arrangement of the service information in one or more pages, which can also be referred to as a data packet or a data string.
  • one or more service information of different lengths can be contained in each page.
  • the service information can be passed on identically, ie unchanged, or changed, for example with further standard information or access codes, from the radio network center of a radio network via intermediate stations to the desired radio cells of the radio network.
  • the standardization of the data structure by pages of constant page length also simplifies the processing of traffic information in the terminal of a service information user, that is to say, for example, in the mobile device of a road user.
  • the groups of radio cells (which can also be referred to as clusters) mentioned in claim 1 are preferably area-covering together.
  • the area coverage of the groups is limited by the area coverage of the radio network etc.
  • a base station can supply one or more radio cells.
  • An area is expediently defined as the radio cell, which is covered by one or possibly also several base stations with sufficient transmission power.
  • a transmission to a group of radio cells as defined in claim 1 can thus be the transmission of information to base stations located within this group of radio cells.
  • the area-wide definition of the groups of radio cells ensures complete operation of the large area covered by a radio network.
  • the groups define disjoint areas. This means that radio cells are not assigned to different groups. However, service information can still be disseminated in any region by specifying several regions by one or more differently defined groups.
  • the radio network is expediently designed according to the GSM standard, since most of the subscribers can be reached with it.
  • pages are sent from the radio cells, that is to say from the base stations located in the radio cells, at specific time intervals, in particular at 150-second intervals, in order to enable the service information users to obtain inexpensive, up-to-date information.

  • the spatial sub-areas assigned to individual groups do not overlap with regard to the assignment. Furthermore, it is expedient if, as in FIG. 2, the spatial partial areas assigned to the individual groups together cover the entire area covered by the radio network without gaps. Groups can also be of different sizes; a group can also include several of the hexagons shown.
