Abstract: The invention relates to communication of information in fixed-length messages in mobile communication systems, particularly in association with positioning methods. In a method according to the invention information is transferred in a fixed-length message such that the payload portion of the message includes content information to define the contents of the payload portion of the message, and in accordance with the content information the payload portion of the message includes information elements defined by the content information.

Abstract: A Network Assisted Mobile Terminal GPS system includes a plurality of GPS-capable mobile terminals (10) each having a transceiver, and a wireless telecommunications network (32) having at least one base site transceiver (30) for transmitting GPS Assistance Data to individual ones of the plurality of GPS-capable mobile stations using a point-to-point signalling protocol. In the illustrative embodiment described herein the point-to-point signalling protocol is comprised of at least one of an IMSI (International Mobile Subscriber Identity) Attach, a Normal Location Update, or a Periodic Location Update signalling protocol.

Abstract: In a communications system, the subscriber data in a home network (HLR) of a subscriber (UE) is provided with a subscriber ciphering profile which indicates whether an unciphered call, session or data packet is to be rejected, accepted or handled in some other manner. A serving network (MSC/VLR, SGSN,UTRAN) checks the subscriber ciphering profile in one or more of the following cases: 1) for each setup of an unciphered call or connection, 2) for each unciphered packet switched data transmission session, or 3) for each packet data transmission originating from subscriber equipment, and rejects or accepts the unciphered call, connection, session, or data packet, respectively, according to the subscriber ciphering profile. As a result, unciphered calls, sessions, or packet data transmissions will be reliably rejected if the network operator or the user sets the subscriber ciphering profile accordingly.

Abstract: A method for transmitting connection setup parameters of a packet data network on broadcast control channels in a telecommunication system, which comprises at least one cell which uses a circuit-switched and a packet-switched broadcast/common control channel. At least one mobile station supports the packet data network, the mobile station being arranged to listen to at least one of said broadcast/common control channels. The connection setup parameters of the packet data network are transmitted to mobile stations in the cell on both broadcast control channels if the cell supports the transmission of the connection setup parameters of the packet data network on both broadcast control channels. The mobile station transmits a DCCM indication to the packet data network if the mobile station is able to receive control messages on both common control channels, and the telecommunication system is controlled to transmit control messages to the mobile station on one common control channel.

Abstract: A cellular radio system comprises terminals (401, 402) arranged to transmit a specific message of a predetermined form at least two times (408, 409; 413, 414), so that there is a predetermined time-out between the two successive messages of said form. A message of said form, which is received from a terminal, is attached (503, 507, 509) to a code representing the terminal in order to identify an illegal terminal. Such a terminal is regarded as identified (513, 514) for which the time between the reception of the two successive messages of said form attached to the code representing the terminal is shorter than said time-out.

Abstract: When a mobile station (10) is in a DCCH camping state it monitors its assigned page frame. After making RSSI and possibly also Bit Error Rate/Word Error Rate (BER/WER) measurements the mobile station monitors the rate of change of the RSSI. If the rate of change is small and remains so, the mobile station is assumed to be in a stationary state. After determining that it is stationary, the mobile station may give an audible alert and/or display a message to request the user to confirm that the mobile station is (and will remain) stationary. When in the stationary state the mobile station inhibits making neighbor channel measurements for DCCH reselection. The mobile station continues to monitor its assigned page frame within an assigned digital control channel and to measure its own channel RSSI and possibly also the BER/WER. If these values subsequently indicate that the mobile station is no longer stationary, the mobile station immediately resumes all neighbor channel measurements.

Abstract: The object of the invention is a method to realize discontinuous transmission (DTX) in a telecommunications network, e.g. in a GSM (Global System for Mobile Communications) mobile phone network, particularly on the downlink. The disadvantage of known methods is that dummy bursts transmitted on the frequency of the broadcasting channel cause disturbing responses in a mobile phone, when frequency hopping is used. In the solution according to the invention the bursts transmitted on the frequency of the broadcasting channel are encoded so that after decoding the mobile phone prevents information contained in a dummy burst to be interpreted as speech. In this way the mobile phone responds with noise on the dummy bursts transmitted on the broadcasting frequency.
