A package is configured to hold an information carrying card. The package includes a first panel connected to a second panel via a first fold line. The first panel includes a first opening. A third panel is connected to the second panel via a second fold line, the third panel includes a second opening. In a state where the first panel has been folded to overlap the second panel via the first fold line and the second panel has been folded to overlap the third panel via the second fold line, the first opening at least partially overlaps the second opening. The package may include a card on which data is stored. The data is exposed through the first and second opening to an environment outside the package.
摘要:
In a satellite mobile telecommunications system based on the GSM standard, and using a TDMA frame structure, discontinuous transmission (DTX) mode is used to take advantage of the substantial silences which occur during normal speech. In this mode, traffic channel (TCH) data is not sent, but control of the link between a ground station and a user terminal is maintained by sending control channel data bursts (SACCH) together with silence descriptor (SID) frames. To avoid high peak to mean values of transmission power at the satellite, the emission time of the bursts is controlled so as to be uniform over the available sending opportunities. Conventional techniques for doing this cannot be used in a system which includes diversity operation. Therefore, the burst transmission time at the ground station is set in dependence on a reference provided by the user terminal which is a modified version of the reference generated for contention resolution of random access requests.

In a satellite mobile telecommunication system, TDMF traffic is transmitted from a SAN 1 via a satellite 3 to a mobile user terminal UT1, over a duplex link 1, 2. The SAN 1 instructs the satellite 3a to transmit signals over link 1 to UT 1 at a power level dependent upon the quality of signal received by UT 1, so as to adaptively control the power to an efficient level. Similarly, the power level of signals transmitted by UT 1 to the satellite is controlled depending on the error rate. The power level required is computed as a function of the average of easured areas determined during a given measurement period together with a margin which is computed as an adaptive function of a deviation of the errors bout the average value.

摘要:
A mobile communication system has a plurality of satellites and mobile stations. A mobile station is capable of communicating with more than one satellite. A satellite transmits a set of neighboring cell data to one of the mobile stations. The data set comprises first and second portions related to communication with a first and a second satellite of the plurality of satellites, respectively. When the data set is received the first time by the mobile station, it decodes both first and second data portions to establish a neighboring cell list, which is stored within the mobile station. When the mobile station receives subsequent transmissions of neighboring cell data, it need only decode either the first data portion or the second data portion based on the presence or absence of an alert message.

In a cellular satellite mobile telecommunication system, cell reception measurements for cell broadcast channels (BCCH) at a user terminal (UT 1) are made in an idle mode when no call is being made. At the commencement of a call, the measurement information (31, FIG. 8) relating to the measurement made in the idle mode is encoded onto a slow control channel (SACCH up) associated with a speech channel (TCH) for speech communication from the user terminal to a remote ground station (SAN 1) via a satellite (3a), and the power of the speech channel transmitted to the user terminal from the satellite, and from the UT to the satellite, for the call, is set in dependence upon the report. The reported data can also be used to determine whether to make a cell or satellite handover.
