Abstract:
The present disclosure provides a method (200) in a network device for transmission of Narrow Band -Internet of Things (NB-IoT) data between a Radio Equipment Control (REC) node and a Radio Equipment (RE) node over Common Public Radio Interface (CPRI). The method (200) comprises: transmitting (210) the NB-IoT data from the REC node to the RE node or from the RE node to the REC node in a Control and Management (C&M) region of a CPRI frame. The NB-IoT data is frequency-domain data.
Abstract:
A receiver for combining multiple data streams at a destination device, where at least one of the multiple data streams may be a redundant data stream sent intermittently to a destination device. The redundant data stream may be sent intermittently depending on the availability of resources available to a source device. Based on monitoring of quality of service (QoS) parameters of an original data stream on the uplink, a base station functioning as an auxiliary receiver may be intermittently activated to intercept the data stream as a redundant data stream. The auxiliary receiver may then send the redundant data stream to the destination device to improve QoS for the original data stream. The receiver may receive the data stream alone, or receive both of the redundant second data stream and the original data stream simultaneously, on an intermittent basis to improve QoS for the original data stream.
Abstract:
A method for cross-domain service optimization is implemented on a computing device and includes defining at least one key quality indicator (KQI) target for at least one end-to-end (E2E) service, where the at least one E2E service crosses more than one domain of a communications network, receiving an indication of quality of experience (QoE) for the at least one E2E service, based on the indication of QoE, translating the at least one KQI target to at least one set of service optimization instructions for each domain from among the more than one domain, and for said each domain, applying the service optimization instructions.
Abstract:
Upon a determination that a relay backhaul link of a relay node is using excessive resources of a donor access node, wireless devices attached to the relay node are offloaded to other access nodes such as neighbor access nodes or to a different frequency band deployed by the donor access node or its neighbors. A donor access node transmits a congestion indicator to the relay node. The relay node transmits updated measurement parameters to end-user wireless devices connected thereto. An end-user wireless device reports back to the relay node in the event it measures a signal strength that is stronger than the current signal strength. This measurement event triggers a handoff of the end-user wireless device, thereby helping to alleviate the resource utilization of the air-interface of the donor access node.
