Facilitating reliable connection admission control for telecommunications system using AAL2 signaling

摘要

In a telecommunications network, for establishing or modifying a radio connection a node (N₁) prepares and sends an AAL2 signaling message (110) for use by a connection admission control function (106) of another node (N₂) of the telecommunications network. In accordance with the present invention, the AAL2 signaling message includes a timescale value (112) which represents a timescale over which at least one bit rate value characterizing the radio connection is defined. Including the timescale value (112) in the AAL2 signaling message (110) facilitates more efficient connection admission control by enabling, e.g., bandwidth requirements of radio connections to take into consideration delay requirements. In an illustrated example embodiment, the timescale value (112) is a burst inter-arrival time (BIT) bit value which is a time which elapses between a beginning of two subsequent bursts of AAL2 CPS (Common Part Sublayer) packets.
