Abstract:
1. A method for resetting a communication connection between a first communication device and a second communication device in a cellular radio system, comprising: detecting the need for resetting the communication connection, transmitting from the first communication device to the second communication device a first piece of information indicating the need for resetting the communication connection, said first piece of information having an indicator value representing using higher priority for transmitting said first piece of information than for transmitting ordinary data in said communication connection; performing a resetting procedure at the second communication device, transmitting from the second communication device to the first communication device a second piece of information indicating the completion of the resetting procedure with respect to the second communication device and using higher priority for transmitting said second piece of information than for transmitting ordinary data in said communication connection, and inserting into a certain piece of information transmitted between the first communication device and the second communication device an indication of an effective number of certain resetting operations associated with a certain detected need for resetting the communication connection; and inserting into a certain piece of information, which is transmitted from the first communication device to the second communication device and indicates the need for resetting the communication connection, a sequence number the value of which remains the same—after the need for resetting the communication connection has been detected—from the first step of transmitting from the first communication device to the second communication device a first piece of information indicating the need for resetting the communication connection to the next step of faultlessly receiving, at the first communication device, from the second communication device a second piece of information indicating the completion of the resetting procedure with respect to the second communication device.
