摘要： The present disclosure generally discloses a scheduling granularity capability. The scheduling granularity capability is configured to improve scheduling granularity in a wireless communication system supporting transport of application flows via radio bearers. The scheduling granularity capability may be configured to support improved scheduling granularity by controlling scheduling at various levels of granularity, such as at the bearer level (e.g., for scheduling bearers with respect to each other), at the application flow level (e.g., for scheduling the application flow of a bearer when the bearer includes a single application flow, for scheduling application flows of a bearer with respect to each other when the bearer includes multiple application flows, or the like), or the like, as well as various combinations thereof. The scheduling granularity capability may be configured to support improved scheduling granularity by identifying application types of application flows supported by the bearers and controlling scheduling, at various layers of granularity, based on the application types of the application flows supported by the bearers.

摘要： The controlling of an operation of an application is implemented in a communication network by obtaining network identification and cell load information for a bearer in order to compute an actual transport block size per physical resource block (ATpP) slope for the bearer. A user equipment (UE) location corresponding to the bearer is associated with geographic pixel information in order to calculate an interference vector. The interference vector is used to compute a coverage map tuple that is used to control the operation of the application. Throughput can also be predicted using the coverage map tuple.

摘要： Fast congestion detection is implemented in a wireless radio access network (RAN) to mitigate congestion by classifying bearers into bearer types using bearer metrics and monitoring bearers for type specific anomalies to obtain anomaly data. Congestion is detected based on the anomaly data to obtain congestion information that is exported to a network node to mitigate network congestion. Bearer metrics include radio link protocol (RLC) buffer size information, physical resource block (PRB) utilization information, and transmission burst interval information. The transmission burst interval information includes information on time intervals between successive time periods when a RLC buffer is empty. The bearers are classified into Type I and Type II bearers. Type I bearers are bearers displaying bursty data transfer behavior, and Type II bearers are bearers displaying a continuous stream of data transfer behavior.

摘要： A smoothed transport block size is forecasted by predicting future value information based on historical time series data obtained at an e-Node B. The historical time series data includes historical transport block size information and historical modulation and coding scheme information. A mapping function is used to correlate the future value information with historical transport block size information. Once the mapping function is determined, the mapping function forecasts the average transport block sizes by inputting the future value information into the mapping function. The smoothed transport block sizes and the future value information is then transmitted to an application server and/or an application client at a user equipment to control an operation of an application.

摘要： Multicast/broadcast offload session (MBOS) anchor logic is provided to establish an offload session to an MBOS gateway to provide a multicast/broadcast stream to user equipment in response to the user equipment handing off from a first access point to a second access point. The MBOS anchor logic is to establish the offload session concurrently with providing the multicast/broadcast stream to the user equipment via the first access point. MBOS gateway logic is provided to terminate the offload session and forward content to the user equipment. User equipment including MBOS management logic is provided to trigger establishment of the offload session terminated by the MBOS gateway for providing a multicast/broadcast stream to the user equipment in response to the user equipment handing off from a first access point to a second access point. The trigger is provided concurrently with the user equipment receiving the multicast/broadcast stream via the first access point.

摘要： An application type of a bearer is classified by computing statistics vectors of bearer metrics and locating points on a label map corresponding to the statistics vectors to obtain application type information. The application type information is exported to a network node to control an operation of application. The bearer metrics include bearer identifier information and bearer condition information, where the bearer condition information includes channel condition information and cell congestion level information. The bearers are paired, such that uplink and downlink bearers for a same application are identified, so that paired bearers are classified together. The label map is produced using previously classified bearer information to calculate cluster centroids and cluster regions that define portions of the map for particular application types. The bearer is classified by determining which cluster region is closest to points on the label map that are associated with the statistics vectors for a particular bearer.

摘要： The present invention provides a method of data path switching. Embodiments of the method include transmitting a packet from a node in a communication system during hand off of a mobile node from a source access network to a target access network. The packet includes an end marker that indicates that the packet is the last packet to be transmitted during the hand off over a source link between the mobile node and an anchor node via the source access network during the hand off. Embodiments of the method also include switching, at the node, a transmission data path from the source link to a target link between the mobile node and the anchor node via the target access network following transmission of the packet including the end marker.
