Abstract
In a telecommunications system, in which a connection comprises a part with an interworking function at both ends, a channel is allocated to the connection between the interworking functions. The required channel capabilities may vary during the connection, whereby the channel capabilities should be changed. When the first interworking function detects that a channel capability must be changed, a first message, which indicates the desired capability change, is transmitted (2-1) to the second interworking function; and the channel capability is changed (2-3,2-5) into the desired one at both ends of the part.
Claims20
A method for use in a first interworking function for communicating with a second interworking function, the method comprising:
- detecting, at the first interworking function, that a channel capability change is desirable by monitoring a channel allocated to a connection;
- transmitting, to the second interworking function, a first message that indicates that the channel capability change is desirable;
- receiving a second message from the second interworking function indicating whether the channel capability change can or cannot be performed;
- and
- on a condition that the channel capability change cannot be performed, the first interworking function re-transmitting the first message after a predetermined time period, or the first interworking function receiving, from the second interworking function, an indication of a new desired capability change that can be performed at the second interworking function.
A first network device for communicating via a communication channel with a second network device that includes a second interworking function, the first network device comprising:
- a first interworking function configured to detect that a channel capability change is desirable by monitoring a channel allocated to a connection;
- a transmitter configured to transmit, to the second interworking function, a first message that indicates that the channel capability change is desirable;
- a receiver configured to receive a second message from the second interworking function indicating whether the channel capability change can or cannot be performed;
- and
- the first interworking function being further configured to, on a condition that the channel capability change cannot be performed, re-transmit the first message after a predetermined time period, or receive, from the second interworking function, an indication of a new desired capability change that can be performed at the second interworking function.
