  • Patent number: 6741854
    Abstract: A cordless telecommunications system (CTS) with a base station (CTS-FP) and with at least one mobile station (MS) initialised at the base station (CTS-FP), for carrying out a process for transmitting operating parameters from a control centre (Z) of a superimposed telecommunications network (PLMN; PSTN, ISDN), which transmits operating parameters initially to the base station (CTS-FP) or to one of the mobile stations (MS) of the cordless telecommunications system (CTS) and then relays the operating parameters to as far as possible all initialised mobile stations or to the base station (CTS-FP) as well as to as far as possible all other initialised mobile stations (MS) is proposed. Thus, new operating parameters can easily be distributed centrally to one or more limited cordless telecommunications systems and can be activated.

  • Patent number: 6359924
    Abstract: Wireless telecommunications systems with at least one base station and with mobile user terminals are known where radio signals are transmitted and received in different time and frequency states. Both on user channels as well as on signaling channels there are radio signals that are transmitted corresponding to the predicted frequency hopping sequence.

  • Patent number: 6311062
    Abstract: A method for establishing a telecommunications link utilizing bursts in a digital radio network having at least one other digital radio network superposed thereon. The bursts of the two digital radio networks have the same bit structure but differ in a specific bit training sequence, and this training sequence of a burst is checked during the establishment of the telecommunications link. By processing only bursts with the training sequences of the desired digital radio network, erroneously received other bursts are filtered out and discarded.
