Patent number: 7230948Abstract: An AAL2 path group (60) comprises plural AAL2 paths (35). Bandwidth of an individual AAL2 path comprising the AAL2 path group is contributed to a total bandwidth of the AAL2 path group rather than to the individual AAL2 path exclusively. An admission decision regarding a connection seeking to use an AAL2 path belonging to the AAL2 path group is based on available bandwidth of the AAL2 path group rather than available bandwidth of an individual AAL2 path. ATM VCCs which comprise the AAL2 path group are transported on a virtual path (VP) together with ATM VCCs of a different type (e.g., a second type which differs from a first type of ATM VCC which comprise the AAL2 path group). The AAL2 path group also features quality of service (QoS) separation, e.g., differing treatment for differing AAL2 connections within the AAL2 path group based on the QoS requirements for the differing AAL2 connections.Type: GrantFiled: June 1, 2001Date of Patent: June 12, 2007Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Mikael Agnevik, Per Wollbrand, Bo Karlander

Publication number: 20060067355Abstract: 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.Type: ApplicationFiled: October 3, 2005Publication date: March 30, 2006Applicant: Telefonaktiebolaget LM Ericsson (publ)Inventors: Staffan Andersson, Mikael Agnevik, Ola Engstrom

Patent number: 6912390Abstract: In a radio access network of a telecommunications system, an end-to-end signaling protocol is utilized to establish plural distinct connection or link segments comprising a radio connection involving a user equipment unit (30). The plural distinct connection segments extend in series between a device (271) in a first radio network control node (SRNC 261) and a device at a base station (282-1) controlled by a second radio network control node (DRNC 262). An example end-to-end signaling protocol is AAL2. Provision of the plural distinct connection segments is advantageous when performing a SRNC relocation procedure to make the second radio network control node serve as the SRNC for the radio connection involving the user equipment unit. After performance of the SRNC relocation procedure, a retained one of the plural distinct connection segments (4001, 5001) can still be utilized, e.g.Type: GrantFiled: April 10, 2001Date of Patent: June 28, 2005Assignee: Telefonaktiebolaget LM EricssonInventors: Staffan Andersson, Mikael Agnevik

Patent number: 6760335Abstract: 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.Type: GrantFiled: January 9, 2001Date of Patent: July 6, 2004Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Staffan Andersson, Mikael Agnevik, Ola Engstrom, Anders Knuutinen

Patent number: 6738381Abstract: A queuing system (230) stores a package (246) derived from an ATM cell, the package including an internal interface header (IIH) and either an ATM cell payload or an AAL2 packet. The queuing system comprises a queue (312, 320) for storing the package, as well as a processor which executes plural functions. A time stamping function applies a time stamp upon storage of the package in the queue. The time stamping function can apply the time stamp to a package as replacement of the internal interface header. A time stamp checking function uses the time stamp to make a determination whether the tenure of the package in the queue is longer than permissible. The time stamp checking function can make the tenure determination in conjunction with a potential readout of the package from the queue. Alternatively, time stamp checking function can make the tenure determination when invoked by a queue monitoring function which monitors a fill level of the queue (e.g., when a queue fill level exceeds a threshold).Type: GrantFiled: November 9, 1998Date of Patent: May 18, 2004Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Johan Mikael Agnevik, Arne Lundbäck, Lars-Göran Petersen, Mattias Östman

Patent number: 6504845Abstract: An ATM switching node has a queuing resource (230) connected to an ATM switch core (30). The queuing resource provides centralized queuing for ATM cells destined for routing through the ATM switch core to plural output links. The ATM switch core routes an ATM cell destined for any output link requiring queuing to the centralized queuing resource. ATM cells for output links not requiring queuing are not directed to the queuing resource. The queuing resource has a link multiplexer (280) for each output link which is handled by the queuing resource. Each link multiplexer has both a first stage (304) and a second stage (302). The second stage comprises plural queues (312) for storing ATM packets and a second stage multiplexer (314) for selecting the ATM packets stored in the plural queues of the second stage for transmission to the first stage.Type: GrantFiled: November 9, 1998Date of Patent: January 7, 2003Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Lars-Göran Petersen, Arne Lundbäck, Johan Mikael Agnevik, Mattias Östman

Patent number: 6449275Abstract: 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.Type: GrantFiled: December 17, 1998Date of Patent: September 10, 2002Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Staffan Andersson, Mikael Agnevik, Ola Engstrom, Lars-Göran Peterssen
