The invention proposes a method of controlling a network to which a communication device is connected, comprising the steps of obtaining (S) connection capability information from the network and evaluating (S) a connection service based on to the obtained connection capability information. The invention also proposes a correspondingly adapted communication device. Thus, network capabilities related failures may be eliminated since the communication device is aware of the relevant connection capabilities in the network etc.

Service and capability negotiation in a network using single numbering scheme

A method of setting a timer associated with a protocol supportinga data link in a digital mobile communication system in a connection section. At least one party (MSC/IWF, MS) to the connectionsection monitors if the need to change the timer value has arisen. Should such a need be detected, the timer value (S) is set to avalue deviating from the initial value. The need to change the timer value (S) is also determined during the connection, such asin handover, for example by measuring the propagation delay associated with the connection section. This may be implemented by either of the parties to the connection transmitting to the other party a frame (F) which is selected/formed such that the party receiving the frame sends an acknowledgement (Ack) to the transmitting party. The party which transmitted the frame measures the timefrom the moment of transmission of the frame (F) to the arrival of the acknowledgement (Ack) and deduces the propagation delay (D) therefrom.
