Abstract: Various binding information techniques are provided for a telecommunications network (20) having separated call and connection layers. In a first embodiment of the invention, binding information is associated with connection endpoint information for a first connection end point (36A) at a first end node (22A) of the network. In a second embodiment, an ATM end system address (AESA) is associated with a first connection end point at the first end node and is transmitted in the call layer to the second end node, and included in connection layer signaling sent from the call layer to the connection layer. Upon receipt of the connection layer signaling at the first end node, the first end node uses the AESA to through connect the ATM switch in the physical layer to the first connection endpoint. In a third embodiment, a dynamic ATM end system address (AESA) is associated both with a first end node of the network and with a first connection end point at the first end node.

Abstract: AAL2 (ATM Adaptation Layer 2) paths are dynamically established and/or released in an ATM (Asynchronous Transfer Mode) network/system. For purposes of example, during network operation a determination(s) may be made as to whether AAL2 mux (i.e., multiplexor(s) and/or demultiplexor(s)) resources are lacking and/or excessive relating to a particular AAL2 signaling relation(s). When AAL2 mux resources are determined as lacking for the AAL2 signaling relation, then at least one AAL2 mux is added to the relation. However, when AAL2 mux resources are determined as excessive for the AAL2 signaling relation, then at least one AAL2 mux is removed or dropped from the relation. AAL2 paths may be selectively and dynamically added and/or dropped from an AAL2 signaling relation in response to the above determinations. In such a manner, ATM resources can be preserved and not wasted thereby resulting in a more efficient ATM AAL2 system/network.

Abstract: An ATM switching node has an ATM switch (30) to which at least one inter-node physical link (56) is connected. In addition, a cell handling unit (32) connected to the ATM switch has a centralized queuing resource (230) which queues ATM cells which are to be routed through the ATM switch for transmission from the node on the physical link. ATM cells destined for the physical link from the queuing resource are discharged from the queuing resource in accordance with a parameter of the physical link. The parameter is preferably the capacity (e.g., transmission rate) of the physical link. In the illustrated embodiment, the node is one of the following nodes of a cellular telecommunications network: a base station (42); a base station controller (44); a mobile switching center (46).

Abstract: An internal routing tag (82) is appended to a payload of a received ATM cell upon ingress of the ATM cell into a multi-stage ATM node (20). The routing tag comprises routing information for routing the payload of the received ATM cell through plural stages (22) of the multi-stage node. Preferably the routing information comprises a list of destination addresses, e.g., utopia address of physical units (26) in the multi-stage ATM node. Use of the internal routing tag streamlines connection setup, reduces the number of internal control paths required, and obviates VPI/VCI conversion at the plural stages of the multi-stage node.
