Method and system for controlling links in an integrated services digital network

摘要

The method of the invention consists mainly in the partial analysis of the HDLC frames interchanged between a local switching exchange (11) and a subscriber network terminal equipment (15-j). The HDLC frames are generated by means in the local exchange (11) for transporting the information in a call established in an ISDN network.;A first transfer unit (21) verifies the value of the service access point identifier SAPI contained in the HDLC frame. Depending on its value, it allocates an appropriate number of radio channels to the call to be established.;As a result of the foregoing, an optimum allocation of the radio channels is produced and, in addition, efficient management thereof takes place.
