Abstract
The present invention relates to data communication systems. In the disclosed method a data channel is first activated between a first and a second station. A timer function is started so as to control the state of the data channel. The data channel is maintained in a ready state at least until the timer function indicates an expiry of a predefined period. The arrangement is such that after a data transmission is initiated on the data channel the state of the data channel is prevented to be changed from the ready state to another state based on the timer function. The change is allowed only after a predefined event occurs. The system may be provided with a further timer that is implemented in a lower function layer than said timer function.

16. A communication system comprising:
-
a first station and a second station, wherein a data channel can be established for data communication between the stations;
a timer function for provision of an indication based on which the state of a data channel established between the two stations is changed from a ready state to another state; and
a control function responsive to said timer function and for controlling the state of the data channel, the arrangement being such that the data channel is prevented to change from the ready state to said other state based on the timer function until a predefined event has occurred.

28. A station for a communication system, said station comprising:
-
communication means for establishing a data channel for data communication between the station and another station;
a timer function for provision of an indication based on which the state of a data channel established between the station and said other station is to be changed from a ready state to another state, wherein the arrangement is such that the data channel is prevented to change from the ready state to said other state based on the timer function until occurrence of a predefined event.
