Abstract: A method and apparatus for handling a call transfer from a circuit switched access network to a packet switched access network. A Mobile Switching Center Server receives a notification that a call for a terminal requires handover from a circuit switched access network to a packet switched access network. The MSC Server determines whether the terminal is currently registered in an IMS network and/or whether the MSC Server is registered such that it can perform handover from the circuit switched access network to the packet switched access network. If so, then return Single Radio Voice Call Continuity is invoked to perform a handover of the call from the circuit switched access network to the packet switched access network. If not then the MSC Server invokes error handling procedures.

Abstract: The invention proposes a method and an apparatus for reducing break duration in handover of a VoIP conversation from a packet switch domain to a circuit switch domain. The main idea is that a synchronization mechanism is introduced between the session handover procedure at IP multimedia subsystem IMS layer and a cell handover procedure at layer 2, so that enable the two handover procedures to start at or almost at the same time. When a Mobile Switching Center MSC server receives a request of handover from the source Mobility Management Entity MME, the time required from the time the MSC server transmitting a message to this message arriving at a remote end user equipment UE is computed first, and then is compared with a predetermined time required from the time the MSC server transmitting a message to this message arriving at the local UE.

Abstract: Techniques are described which provide mechanisms for dual-homing an access ring for virtual private wire service (VPWS) Ethernet line (E-Line) services. The mechanism may provide resiliency against access ring failures and offer a restoration time of 50 msec upon failure. A method to provide such resiliency may generally include determining, at a first ring port of an access node, a ring failure in an Ethernet ring. Upon determining the first ring port of the access node is not situated on a same side of the Ethernet ring as a node designated as a ring protection link (RPL) owner, a message is transmitted on a second ring port of the access node towards a provider edge (PE) node. The message is used to activate pseudowires (PWs) at the PE node for virtual local area networks (VLANs) of the access node.

Abstract: Described embodiments provide for restructuring a scheduling hierarchy of a network processor having a plurality of processing modules and a shared memory. The scheduling hierarchy schedules packets for transmission. The network processor generates tasks corresponding to each received packet associated with a data flow. A traffic manager receives tasks provided by one of the processing modules and determines a queue of the scheduling hierarchy corresponding to the task. The queue has a parent scheduler at each of one or more next levels of the scheduling hierarchy up to a root scheduler, forming a branch of the hierarchy. The traffic manager determines if the queue and one or more of the parent schedulers of the branch should be restructured. If so, the traffic manager drops subsequently received tasks for the branch, drains all tasks of the branch, and removes the corresponding nodes of the branch from the scheduling hierarchy.

Abstract: Disclosed is a method for transmitting channel quality indicator (CQI) during a sleep mode operation. The method for transmitting CQI includes: receiving a message including a CQI-related parameter indicating a transmission of a CQI before a listening window; transmitting a CQI during a sleep window before the listening window according to a CQI-related parameter in the message; transitioning to the listening window according to a listening window-related parameter after transmitting the CQI; and waiting for receiving a message indicating whether or not there is data or traffic transferred from the base station during the listening window.

Abstract: An Ethernet cable used with an Ethernet test-set allows a single connection to an Ethernet port of a network element while maintaining individual connections to separate ports on the test-set. The far-end of the signal path is a single Ethernet cable port having its transmit and receive pins interconnected. The far-end port interconnections cause a test signal which has traveled to the far-end port to be returned to the test-set and to be receive in a test-set port other than the originating port Two signal paths can be simultaneously tested with the same test-kit. Interconnections between the test-set ports by way of the cable maintain a “no-signal”alarm disabled, which otherwise would be energized because there is no signal being received in the port from which the test signal originated.

Abstract: Dynamic adjustment of offset between timebases of separated electronic circuits is provided based on an amount of time between synchronization events, wherein a synchronization event is an event involving communication across a separation between the separated electronic circuits in order to synchronize the timebases. The dynamic adjustment can be dynamically or adaptively adjusting a margin of error to account for drift that may have occurred since a prior synchronization event. Adjustments might be done by applying a learning sequence to quantify and adjust for static or slowly varying delays between the timebases and coordinating the timebases using output of the learning sequence.

Abstract: The invention concerns a method of performing an intra-segment handover (HO) of a mobile station (MS) from a source access point (AP1) of a tree-structured segment (S1) of an Ethernet-compliant telecommunication network to a target access point (AP2) of said segment (S1), as well as a switch (SW-123) to support the execution of this method. After establishing contact between the mobile station (MS) and the target access point (AP2), the mobile station (MS) sends an update entry request addressed to the segment gateway switch (GW). The update entry request is received by a switch (SW-123) positioned in the tree structure of the segment (S1) hierarchically above the source and target access points (AP1, AP2) and below the segment gateway switch (GW). The switch (SW-123) checks whether its forwarding database contains a first entry comprising an address of the mobile station (MS) received by means of the update entry request.

Abstract: Managing RF spectrum usage by secondary, or unlicensed, devices in portions of the RF spectrum where licensed, or primary, services operate is a requirement of cognitive radio systems. To perform the necessary spectrum scanning, a transition period, such as a TTG or RTG can be extended and the scanning performed during the extended period. The presence of a primary service signal can also detected by detecting an energy signature of the primary service signal in a known sequence. In both cases, there is no need to define quiet periods during which secondary devices scan the RF spectrum, thus resulting in saving of resources and improved QoS.

Abstract: A switch device includes a packet forwarding table for providing load balancing across servers in a server group. Each table entry maps a hash value to a server in the server group. A hash value can be computed from the destination MAC address, destination IP address, and destination service port in the header of a received packet. The packet forwarding table is searched to find an entry with a hash value that matches the computed hash value and to identify the server to which the matching hash value maps. The switch device forwards the packet to the identified server. Implementing load-balancing decisions in hardware enables packet switching at the line rate of the switch ports. In addition, the hardware-based load balancing performed by the switch device eliminates session tables and the memory to store them, enabling the switch device to handle an unlimited number of client connections.
