  • Patent number: 7516473
    Abstract: The present invention relates generally to the field of signaling of information, and particularly to a method and a system for signaling information in transmission systems. Methods for signaling information in transmission systems do have certain disadvantages, like the use of an additional channel for signaling or the use of a large number of bits for signaling. The present invention facilitates highly protected and highly reliable signaling requiring only a minimum of bits by inserting an individual signaling information into individual frames and by additionally partitioning signaling information and inserting the partitioned signaling information into different frames, i. e. spreading the signaling information.

  • Patent number: 5809424
    Abstract: A process for locating mobile stations in a cellular mobile radio network with several spatially distributed fixed base stations associated each to several cells and several mobile stations. The network has storage devices which contain information about the identify of the mobile stations and about the cells in which the individual mobile stations were last signaled. In order to locate a mobile station in as flexible as possible a manner, but also if required as precisely as possible, the information in the storage devices is used for approximately locating the searched-for mobile station and at least one direction finding is carried out in order to more precisely locate the mobile station. A cellular mobile radio network for carrying out this process is characterized in that the individual stations are each in communication with a direction finder and that the mobile radio network has a locating central office in communication with all direction finders.
