Abstract: A method executed by an optical line terminal (OLT) in a passive optical network (PON). The PON includes a plurality of optical network units (ONUs) coupled with the OLT through an optical fiber, the ONUs sharing a bandwidth of the optical fiber. The method includes receiving, from the ONU, an energy conservation message indicating support for the reduced buffer memory size. The reduced buffer memory size is calculated based on the maximum committed transmission rate and the burst size limit for the downstream traffic intended for the ONU. A notification is transmitted to the ONU indicating that a portion of the buffer memory can be powered down such that only the reduced size of the buffer memory remains in operation, and downstream traffic intended for the ONU is transmitted at an average transmission rate and burst size not exceeding the maximum committed transmission rate and the burst size limit.

Abstract: The present invention relates to the field of communications technologies, and in particular, to an online charging method, apparatus, and system based on a number portability service. When a calling UE in an IMS network initiates a call to a called UE, after receiving an invite message sent by a CSCF entity in the IMS network, an AS in the IMS network queries number portability information corresponding to a number of the called UE and sends a number of the calling UE and the found number portability information to an OCS in the IMS network, so that the OCS is capable of performing charging authentication for the calling UE according to the number portability information and the number of the calling UE. When the called UE has changed a subscription network and subscribed to an NP service, the OCS is thus capable of correctly performing charging authentication.

Abstract: A wireless communication network system includes a first wireless communication device; and second wireless communication devices. The first wireless communication device selects a master unit from among the second wireless communication devices, on the basis of reception quality and storage battery remaining levels, and sends, to the selected master unit, a master unit request and a storage battery remaining level threshold for the master unit. The selected second wireless communication device operates as the master unit in accordance with the master unit request, and monitors the storage battery remaining level of the selected second wireless communication device on the basis of the storage battery remaining level threshold. When the storage battery remaining level of the selected second wireless communication device does not match the storage battery remaining level threshold, the selected second wireless communication device sends a master unit change request to the first wireless communication device.

Abstract: A system and method of scheduling communication in a wireless communication network are provided. A scheduling scheme comprising a first subframe and a second subframe can be determined to communicate data between a first access node and first wireless devices, and a second access node and second wireless devices. A resource request can be received from one of the first wireless devices. An interference indication can be determined based on the resource request. The first access node can be instructed to communicate with the first wireless devices during the first subframe and the one of the first wireless devices can be instructed to transmit data to the first access node during the second subframe when the interference indication meets an interference criteria. The second access node can be instructed to transmit data addressed to at least one of the second wireless devices during the second subframe.

Abstract: IP2 calibration efficiency can be improved by passing the calibration signal through the transceiver's duplexer instead of inserting the calibration signal directly onto transceivers receive circuit. Passing the calibration signal through the duplexer may reduce IP2 calibration periods for transceivers having less-permeable duplexers, or duplexers that provide better than average separation between the RX and TX circuits. IP2 calibration inefficiencies can also be reduced by using a binary-like search when computing the in-phase and quadrature-phase path correction coefficients of the IP2 correction code.

Abstract: The disclosure relates to test-capable pluggable transceivers and network systems and methods using such transceivers. A central test server generates a test request and communicates to a mediation sub-system, which uses a common management protocol to communicate with a plurality of transceivers in the network. The mediation sub-system translates the test request into sub-tests and generates sequences of test-control commands for executing by specific transceivers to configure test logic deployed within the transceivers for testing designated network services, to generate test frames, and/or to process received frames to collect test results.

Abstract: A communications network is operated by providing a plurality of redundant links between a first network node and a second network node. A first identifier is associated with a first one of the plurality of redundant links and a second identifier is associated with a second one of the plurality of redundant links. The first and second identifiers are associated with the regulatory constraint. Traffic that is marked with the first identifier is routed to the first one of the plurality of redundant links and traffic that is marked with the second identifier is routed to the second one of the plurality of redundant links so that operation of the communications network is in compliance with the regulatory constraint.

Abstract: The present disclosure presents a method and apparatus for dynamically configuring a cell update message at a user equipment (UE). For example, the method may include determining that a size of the cell update message at the UE is above a threshold value after a “measured results on random access channel (RACH)” information element (IE) is excluded from the cell update message. Furthermore, such an example method may include removing one or more IEs from the cell update message until the size of the cell update message is at or below the threshold value. As such, dynamic configuration of a cell update message at a UE is achieved.

Abstract: A method to facilitate late entry of a late entrant node into an ad-hoc radio network involves accessing from a memory at the late entrant node an initial frequency hopping sequence for the ad-hoc radio network. The late entrant node uses at least the initial frequency hopping sequence to determine a first frequency to monitor during a communication epoch corresponding to one of the frequency hops. The late entrant node thereafter monitors the first frequency to detect the presence of a beacon signal transmitted by a participating node of the network. Subsequently, the late entrant node determines a second frequency included in the current hopping sequence of the network based on information contained in the beacon signal.
