  • Patent number: 7177624
    Abstract: A method and an arrangement are disclosed for a mobile station (111) of a cellular radio system to exchange capability information with the fixed parts (101) of the cellular radio system. The mobile station receives (513, 513?) capability information (103) from discussed parts (101) if the cellular radio system and compares (515, 516, 517, 517? 518, 518?, 519, 520) the received capability information (103) to a piece of capability information (112) describing the capability of the mobile station (111). The mobile station transmits (522, 522?) to the fixed parts (101) of the cellular radio system a comparison result (113) that indicates whether matches occurred between the received capability information (103) and said piece of capability information (112) describing the capability of the mobile station (111).

  • Patent number: 6987779
    Abstract: A method and an arrangement are provided for indicating the specific use of a packet-switched communication connection between a mobile station and a fixed packet-switched data transmission network. The activation of a new packet-switched communication connection involves the step of transmitting an activation request message with a service type indicator field for which a set of service type indicator values have been defined. An additional step is performed for transmitting within the activation request message an indicator value indicating the specific use, in more detail than the service type indicator values, of the packet-switched communication connection the activation of which is requested with the activation request message.

    Abstract: A method and an arrangement are disclosed for a mobile station (111) of a cellular radio system to exchange capability information with the fixed parts (101) of the cellular radio system. The mobile station receives (513, 513′) capability information (103) from discussed parts (101) if the cellular radio system and compares (515, 516, 517, 517′ 518, 518, 519, 520) the received capability information (103) to a piece of capability information (112) describing the capability of the mobile station (111). The mobile station transmits (522, 522′) to the fixed parts (101) of the cellular radio system a comparison result (113) that indicates whether matches occurred between the received capability information (103) and said piece of capability information (112) describing the capability of the mobile station (111).
