Abstract

A pager system which includes a base transceiver station (2) for the wireless transmission of data in conformity with the GSM standard, an SMS center (5) for the storage of pager short messages, which center is connected to the base transceiver station (2) so as to transmit data, and at least one pager device (9) which includes a transmit/receive unit (2) which operates in conformity with the GSM standard for the wireless reception of pager short messages from the base transceiver station (2), an output unit (15) which is connected to the transmit/receive unit (10) so as to transmit data for the display of the pager short messages received, and a power consumption control unit which is constructed in such a manner that it switches over the pager system (1) from a normal mode of operation to a power saving mode for selectable periods of time.

Claims

1. A pager system which includes

a) a base transceiver station (2) for the wireless transmission of data in conformity with the GSM standard,

b) an SMS center (5) for storing pager short messages which is connected to the base transceiver station (2) so as to transmit data, and

c) at least one pager device (9) which includes

i) a transmit/receive unit (10) which operates in conformity with the GSM standard for the wireless reception of pager short messages from the base transceiver station (2),

ii) an output unit (15) which is connected to the transmit/receive unit (10) so as to transmit data in order to display the received pager short messages, and

iii) a power consumption control unit which is constructed in such a manner that it switches over from a normal mode of operation to a power saving mode for predetermined periods of time.

2. A pager system as claimed in claim 1, characterized in that there is provided an input unit (7) which is connected to the SMS center (5) so as to transmit data for the input of pager short messages.

3. A pager system as claimed in claim 1 or 2, characterized in that there is provided a central data processing unit (12) which is connected to the transmit/receive unit (10) and the output unit (15) so as to transmit data.

4. A pager system as claimed in claim 3, characterized in that the power consumption control unit includes a clock control unit (17) for influencing the clock frequency.

5. A pager system as claimed in claim 3 or 4, characterized in that the power consumption control unit separates the transmit/receive unit (10) and/or the output unit (15) and/or the central data processing unit (12) from the power supply for selectable periods of time.

6. A pager system as claimed in one of the claims 3 to 5, characterized in that the central data processing unit (12) controls the transmit/receive unit (10) in such a manner that, in the case of the normal mode of operation, it interrogates the base transceiver station (2) as to whether pager short messages are stored in the SMS center (5), said messages being subsequently transmitted from the base transceiver station (2) to the transmit/receive unit (10).

7. A pager system as claimed in claim 3, characterized in that the power consumption control unit includes a power supply unit (17;

21).

8. A pager system as claimed in claim 7, characterized in that the power consumption control unit includes a switch-on/off control unit (23) which is electrically conductively connected to the power supply unit (21).

9. A pager system as claimed in claim 8, characterized in that the switch-on/off control unit (23) is constructed in such a manner that it ensures switching over from the normal mode of operation to the power saving mode and vice versa.

10. A pager system as claimed in one of the preceding claims, characterized in that there is provided a storage unit (16) which is connected to the central data processing unit (12) so as to transmit data for the storage of pager short messages.
