Abstract
In a telecommunications network, an ATM Adaptation Layer 2 (AAL2) signaling protocol is employed independent of the signaling bearer service being used in transport signaling messages to and from various network entities, such as mobile switching centers, radio network controllers and cell base stations in, for example, a mobile telecommunications network. This is achieved by dividing the functionality of the AAL2 signaling protocol into a number of functional sublayers including an AAL2 Signaling Common Part (CAP), a Bearer Coordination Part (BCP) and a Bearer Adaptor Part (BAP), wherein the BAP adjusts incoming and outgoing messages so that they are compatible with the AAL2 signaling protocol or the underlying signaling bearer service respectively.
