Abstract: In a telecommunications system, in which a connection comprises a part with an interworking function at both ends, a channel is allocated to the connection between the interworking functions. The required channel capabilities may vary during the connection, whereby the channel capabilities should be changed. When the first interworking function detects that a channel capability must be changed, a first message, which indicates the desired capability change, is transmitted (2-1) to the second interworking function; and the channel capability is changed (2-3,2-5) into the desired one at both ends of the part.

Abstract: An egress network device of a point-to-point (P2P) tunnel can receive an LSP Ping message via the P2P tunnel from an ingress network device of the P2P LSP, wherein the LSP Ping message specifies a label that the egress network device associates with a service provided to the egress network device via the P2P tunnel. In response to receiving the LSP Ping message, the egress network device can store an association between the label and the P2P tunnel. The egress network device also uses a fault detection network protocol session over the P2P tunnel to monitor a state of the P2P tunnel. In response to detecting based on the fault detection network protocol session that the state of the P2P tunnel is down, the egress network device determines the service is unavailable from the ingress network device via the P2P tunnel, and selects a new source to provide the service.

Abstract: A network configuration capable of using a paging activity sink to aggregate and analyze flood of paging messages during an idle mode is disclosed. In one embodiment, a process using the paging activity sink is able to detect an idle mode of end user (“EU”) equipment in a communication network. Upon detecting a downstream push data such as push mail addressing to the EU equipment indicating a pending message, a predefined portion of data from the first downstream push data is copied or duplicated to form a copy of paging announcement. While sending the downstream push data to the EU equipment, the process forwards the copy of paging announcement to a network element (“NE”) such as a paging activity server for analyzing paging activities.

Abstract: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting acknowledgement/negative ACK (ACK/NACK) in a wireless communication system which supports carrier aggregation, and to an apparatus for the method. A method in which a terminal transmits ACK/NACK in a wireless communication system that supports carrier aggregation comprises the following steps: receiving a physical downlink control channel (PDCCH); receiving a physical downlink shared channel (PDSCH) indicated by the PDCCH; and transmitting ACK/NACK for the PDSCH via a physical uplink control channel (PUCCH). A PUCCH format for transmitting ACK/NACK is selected by taking the number of aggregated carriers into account.

Abstract: The present disclosure discloses a network device and/or method for preventing loops in routing paths of network frames in a wireless digital network. The disclosed network device at a network node receives a frame from a wired network. The frame includes a site identifier uniquely corresponding to the wired network, a source physical address, and a destination physical address. If the network node is selected as a representative portal node, the network device forwards the frame. Otherwise, if another network node is selected as the representative portal node, the network device drops the received frame to prevent forming a loop in a routing path corresponding to the frame. If not other network is selected as the representative portal node, the network device floods the frame to other network nodes in the wireless network.

Abstract: In general, techniques for facilitating a distributed network (L3) subnet by which multiple independent control planes of network devices connected to physically separate L2 networks provide L2 reachability to/from a single L3 subnet. In some examples, a shared L2 network physically situated to connect a plurality of physically separate L2 networks “stitches” the L2 networks together within the respective, independent control planes of switches such that the control planes bridge L2 traffic for a single bridge domain for the separate L2 networks to the shared L2 network and visa-versa. Each of the independent control planes may be configured with a virtual IRB instance associated with the bridge domain and with a common network subnet. Each of the virtual IRBs provides a functionally similar routing interface for the single bridge domain for the separate L2 networks and allows the shared network subnet to be distributed among the independent control planes.

Abstract: A network device receives initial policer limits for a plurality of over-subscribing ingress ports, where the initial policer limits are based on existing bandwidth limits for an over-subscribed egress port associated with the over-subscribing ingress ports. The network device receives a high threshold watermark and a low threshold watermark for bandwidth usage of the over-subscribed egress port, and identifies a queue, associated with the over-subscribed egress port, with values outside the high threshold watermark or the low threshold watermark. The network device reduces the initial policer limits for the plurality of over-subscribing ingress ports when the queue has values above the high threshold watermark, and increases the initial policer limits for the plurality of over-subscribing ingress ports when the queue has values below the low threshold watermark.

Abstract: A controller connected to a node configured for processing a packet received in accordance with a processing rule that stipulates a matching rule and processing for a packet matching to the matching rule includes a removal request history management unit, a processing rule search unit and a processing rule setting unit. The removal request history management unit retains record(s) of requests made to the node(s) in connection with removing the processing rule.
