摘要： Systems and methods for auto creation of Multicast-Broadcast Single Frequency Network (MBSFN) areas are disclosed. In some embodiments, systems and methods are disclosed for providing different MBSFN area pattern types for different cell coverage and density conditions for better resource usage. In some embodiments, systems and methods are disclosed for providing tools to a customer to plan MBSFN broadcast areas and to automatically generate MBSFN Hexagon areas and allocate a proper MBSFN area pattern for the MBSFN Hexagon areas to avoid manual configuration of the MBSFN area for each cell. In some embodiments, systems and methods are disclosed for providing a solution to help network operators to remote set MBSFN areas' configuration to a network wide Radio Access Network (RAN). In some embodiments, systems and methods are disclosed for providing tools to present cells, cell range, MBSFN area locations, and configurations and enhanced or evolved Node Bs' (eNBs') relationship.

摘要： A SC informs a communication service (CS) node (e.g., GCS AS) of a data transfer start time for the bearer (i.e., the user plane ready time for the bearer). Additionally, in some embodiments, the SC informs the communication service node (e.g., GCS AS) as to a data transfer stop time for the bearer. This provides a distinct advantage because the CS node will now have information as to when it should start (and stop) data delivery, thereby leading to a higher quality of experience (QoE) of MBMS delivery.

摘要： The present disclosure relates to a method 100 performed in a broadcast multicast service center, BM-SC, node 10 for providing an on-request service to an end-user device 5. The method 100 comprises obtaining 101, from a content delivery node 4, the size of a file of the on-request service; determining (102), based on the obtained file size, one or more parameters related to encoding of the file, thereby establishing a virtual partitioning of the file into a number Z of source blocks; downloading 103, from the content delivery node 4, a source block of the file according to the determined one or more parameters; encoding 104 the source block of the file into encoding symbols according to the determined one or more parameters; and providing 105 the encoding symbols for delivery to the end-user device 5. The disclosure also relates to a BM-SC node 10, computer programs and computer program products.

摘要： There is provided a method in a wireless communications network, the method comprising: broadcasting a content stream as a broadcast service to at least one device using the wireless communications network; and sending to the at least one device a broadcast service status message, the broadcast service status message including the service areas for which the broadcast service will soon cease. By receiving an indication that the broadcast service will cease, before the broadcast service is stopped, the device can take steps to avoid buffer under-run, such as requesting and setting up a unicast service of the same content.

摘要： A method executed on a network node for providing a HTTP streaming service to a UE via broadcasting is suggested. Once it has been determined at the network node that runtime reception reporting is required from a UE for a determined HTTP streaming service, reporting parameters to be applicable for the runtime reception reporting is determined, and provided to the user equipment. At the UE a corresponding method is executed which can identify a request for runtime reception reporting for a certain session. Based on received reporting parameters, the reporting process is determined and initiated. A UE and a network node capable of executing the suggested method steps are also suggested.
