Abstract: A wireless communication system using radio resources for transmission of backhaul data between one or more mobile stations and at least one network control node, a first backhaul transmission link (L_1) being used for transmission of backhaul data and at least one second backhaul transmission link (L_2) being used for transmission of backhaul data. The first backhaul transmission link (L_1) operates as a main backhaul transmission link and the second backhaul transmission link (L_2) operates as an auxiliary backhaul transmission link, and the second backhaul transmission link (L_2) uses at least a part of the radio resources for transmission of backhaul data when in operation.

Abstract: The present invention relates to a method for transmission of backhaul data in a wireless communication system, said wireless communication system being adapted to use radio resources for transmission between one or more mobile stations and at least one network control node, said method using a first backhaul transmission link (L1) for transmission of backhaul data and using at least one second backhaul transmission link (L2) for transmission of backhaul data, wherein: said first backhaul transmission link (L1) operates as a main backhaul transmission link and said second backhaul transmission link (L2) operates as an auxiliary backhaul transmission link, and said second backhaul transmission link (L2) uses at least a part of said radio resources for transmission of backhaul data when in operation. Furthermore, the invention also relates to a wireless communication system adapted for such transmissions, a control device, a computer program, and a computer program product thereof.

Abstract: A telecommunications platform has a cluster of processors which collectively perform a platform processing function. Plural processors of the cluster have Internet Protocol (IP) capabilities and respective plural IP interfaces. The plural processors of the cluster all have a same IP address. An Internet Protocol (IP) handler distributed throughout the cluster renders the IP interfaces of the plural processors of the cluster exchangeable so that knowledge of which one of the plural processors of the cluster is hosting an IP software application being accessed is unnecessary when selecting one of the plural IP interfaces for connecting to the cluster.

Abstract: 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).

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 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.

Abstract: To form internal control paths in an ATM node (20, 120), “half trails” (HF) are initially established and subsequently connected to form complete trails (FT). In an ATM node having plural node entities (30, 130) or device boards connected to a switch core (24, 124), for each node entity a main control path program (70) executed by a node main processor () initially forms both a listening half trail and a sending half trail extending from the node main processor and switch core. Separately and independently, i.e., without prior communication with the node main processor, an entity control path program (80) executed by an entity processor (50, 150) at each node entity establishes a listening half trail between itself and the switch core. For each node entity, the entity control path program establishes the same VPI/VCI as the listening half trail. The entity processor then receives on its independently established listening half trail (i.e., on the predetermined VPI/VCI) a handshaking request.
