Method for operating a communication system and objects for such a system
First Claim
1. A method for operating a communication system for communication between a central station and a plurality of remote objects, the method comprising:
- operating said objects in a battery saving mode in which an object is switched alternately between a wake period for conducting communication between the object and the central station and a sleep period in which communication is inactive, wherein a predetermined first time (t0) and a predetermined time interval (Dt) is designated to each of the objects for initiating the wake periods at times t0+n (Dt), where n equals increasing integer numbers beginning from zero.

Abstract
Method and arrangement for operating a communication system for communication between a central station (10) and one or a plurality or remote objects (20 to 25), as well as such an object, wherein at least one object is operated in a battery saving mode in which it is switched alternatively between a wake period for conducting communication between the object and the central station and a sleep period in which communication is inactive. Each object is designated a predetermined first time (t0) and a time interval (Dt), wherein each object initiates the wake periods at times t0+n (Dt) with n=0, 1, 2, . . . and wherein the time interval is longer than the wake period.

16. A method for operating a communication system for communication between a central station and a plurality of remote objects, the method comprising:
- operating a system of a plurality of objects, said objects including at least one remotely traveling vehicle that carries electricity consuming devices on-board, in a battery saving mode in which each of the plurality of object is switched alternately between (1) a wake period during which communications are conducted between the object and a central station and (2) a sleep mode in which communication is inactive; and
wherein a predetermined first time (t0) and a predetermined time interval (Dt) is designated to each of the objects for initiating the wake periods at regular intervals at times t0+n (Dt), where n equals increasing integer numbers beginning from zero. - View Dependent Claims (17, 18, 19, 20)
- operating a system of a plurality of objects, said objects including at least one remotely traveling vehicle that carries electricity consuming devices on-board, in a battery saving mode in which each of the plurality of object is switched alternately between (1) a wake period during which communications are conducted between the object and a central station and (2) a sleep mode in which communication is inactive; and

21. A computer readable medium storing a computer program, comprising:
- computer program code means run on a programmable microprocessor means for operating a communication system for communication between a central station and a plurality of remote objects by operating the objects in a battery saving mode in which an object is switched alternately between a wake period for conducting communication between the object and the central station and a sleep period in which communication is inactive, a predetermined first time (t0) and a predetermined time interval (Dt) is designated to each of the objects for initiating the wake periods at times t0+n (Dt), where n equals increasing integer numbers beginning from zero when loaded into internal memory of the programmable microprocessor means.
