Abstract

The invention relates to a mobile communication system including mobile stations comprising transmission means for sending data over the radio path, at least one mobile exchange, and base stations having a data transmission connection with the mobile exchange, traffic channels being allocated to be used by transceiver units of the base stations for providing calls to the mobile stations, the base stations also comprising means for receiving the data sent by the mobile stations over the radio path and for forwarding said data to other parts of the system. In order for the mobile stations to be able to send data more efficiently, at least one predetermined data channel is allocated for the mobile stations to send data. In addition the system includes at least one mobile station comprising control means that independently at predetermined moments control the transmission means of the mobile station to move over to said predetermined data channel for the time the data is sent, in which case the mobile station sends said data on said data channel without a preceding channel allocation.

Claims

1. A method for transmitting data from mobile stations to other parts of a mobile communication system in the mobile communication system comprising base stations having a data transmission connection with a mobile exchange and mobile stations comprising transmission means for sending data, characterized by comprising the steps of

allocating at least one predetermined data channel from the system for sending said data over the radio path from the mobile stations to the base stations,

providing at least one mobile station with control means that independently at predetermined moments control the mobile station to send data on said data channel without a channel allocation preceding the transmission, and

providing at least one of the base stations in the system with means for receiving the data sent on said data channel and for forwarding said data to the other parts of the system.

2. A method as claimed in

claim 1

, characterized by

providing at least one of said mobile stations belonging to the system with means for producing data describing the location thereof, whereby the data sent by said mobile station at said predetermined moments includes the data describing the location of the mobile station,

arranging an application having a data transmission connection with said mobile exchange to the mobile communication system for processing the location data of the mobile stations, and

providing said at least one base station of the system with means for sending the data received from said at least one mobile station through the mobile exchange to said application.

3. A method as claimed in

claim 1

, characterized by connecting at least one mobile station belonging to the system to means for providing telemetry data, whereby the data sent by said mobile station at said predetermined moments includes the telemetry data provided by said means.

4. A method as claimed in any one of

claims 1

to

3

, characterized in that the control means of the mobile station control the mobile station to move at regular intervals onto said data channel for sending data.

5. A method as claimed in any one of

claims 1

to

3

, characterized by

dividing the mobile stations of the system into groups, and

determining a time period recurring at predetermined regular intervals for the mobile station groups, during which time period the control means of the mobile stations in the mobile station group control the mobile stations to move onto said data channel for sending said data.

6. A mobile communication system including:

mobile stations (MS1) comprising transmission means (TRX) for sending data over the radio path,

at least one mobile exchange (MX), and

base stations (BS, BS1) having a data transmission connection with the mobile exchange (MX), traffic channels being allocated to be used by transceiver units (TRX1-TRX5) of the base stations for providing calls to the mobile stations (MS, MS1), the base stations also comprising means for receiving data sent by the mobile stations over the radio path and for forwarding said data to other parts of the system, characterized in that

at least one predetermined data channel is allocated in the system for the mobile stations (MS, MS1) to send data, and in that

the system includes at least one mobile station (MS1) comprising control means (8) that independently at predetermined moments control the transmission means (TRX) of the mobile station to move to said predetermined data channel for the time data is sent, in which case the mobile station (MS1) sends said data on said data channel without a preceding channel allocation.

7. A mobile communication system as claimed in

claim 6

, characterized by

said mobile station (MS1) comprising means (7) for providing data describing the location of the mobile station and feeding said data to said transmission means (TRX), whereby the data sent on said data channel of the mobile station describes the location of the mobile station,

the system comprising an application (AVL) having a data transmission connection with the mobile exchange for processing the location data of the mobile station and

the base stations (BS, BS1) of the system being arranged to send the data received from the mobile stations through the mobile exchange (MX) to said application (AVL).

8. A mobile communication system as claimed in

claim 7

, characterized in that said means (7) for providing the data describing the location of the mobile station comprise a GPS receiver.

9. A mobile communication system as claimed in

claim 8

10. A mobile communication system as claimed in

claim 6

, characterized by said mobile station (MS1) comprising means (9) for receiving telemetry data from means providing telemetry data, and means for feeding the received telemetry data to said transmission means (TRX) for forwarding the telemetry data on the data channel, whereby the data sent on the data channel by said mobile station (MS1) consists of said telemetry data.

11. A mobile communication system as claimed in any one of

claims 6
