Abstract: A multi-procedure integrated automatic production line for hard alloy blades under robot control is provided. The production line includes a rail-guided robot. A cutter passivation device and a blade cleaning and drying device are arranged on one side of the rail-guided robot. A blade-coating transfer table, a blade coating device, a blade boxing transfer table, a blade-tooling dismounting device and a blade boxing device are sequentially arranged on another side of the rail-guided robot. The blade-tooling dismounting device is arranged on one side of the blade boxing transfer table. The production line further includes squirrel-cage toolings for carrying the blades. The squirrel-cage tooling that are loaded with the blades can run among the cutter passivation device, the blade cleaning and drying device, the blade-coating transfer table and the blade boxing transfer table. The blades after being treated through the blade-tooling dismounting device are sent to the blade boxing device.

Abstract: 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.

Abstract: A network node initiates a MBMS session providing a multimedia service through a RAN to UEs using a FEC operation providing an initial FEC level, where the multimedia service is concurrently provided through unicast sessions. Feedback reports received from the UEs identify UEs consuming the multimedia service through the MBMS session and identify UEs consuming the multimedia service through the unicast sessions. A ratio is determined of a number of the UEs identified as consuming the multimedia service through the MBMS session to a number of the UEs identified as consuming the multimedia service through the unicast sessions. Responsive to determining that the ratio is less than a target ratio, the FEC level provided by the FEC operation is increased. Responsive to determining that the ratio is greater than the target ratio by a defined margin value, the FEC level provided by the FEC operation is decreased.

Abstract: A method for delivering content. In some embodiments, the method includes a network node adding a first area identifier, AI, to a set of AIs and, after adding the first AI to the set of AIs, determining that an optimized set of AIs should be created. The network node then performs a process for producing the optimized set of AIs, where the process includes: removing from the set of AIs a certain subset of AIs and adding to the set of AIs a second AI. The network node transmits to a second network node a message comprising information identifying each AI included in the optimized set of AIs.

Abstract: It is presented a method for enabling transmission of streaming content in a point to multipoint delivery. The method is performed in a radio network node of a cellular network. The method comprises the steps of: receiving a donor indication message from a wireless device in response to the wireless device receiving a donor command from an application server, the donor indication message indicating that the wireless device requests to be a donor device; setting up a point to multipoint delivery session; obtaining downlink data of streaming content destined for the donor device in a unicast delivery; transmitting the downlink data in a unicast delivery to the donor device; and transmitting a copy of the downlink data using the point to multipoint session, such that the downlink data can be received by a plurality of wireless devices being recipient devices.

Abstract: There is provided mechanisms for allocating an application signalling session for transmitting Multimedia Broadcast Multicast Services (MBMS) data in an MBMS Single Frequency Network (MBSFN). A method is performed by a radio access network node. The method comprises obtaining information identifying the application signalling session from a broadcast multicast service center (BM-SC). The method comprises allocating the application signalling session to a subframe of a radio frame, in which subframe a signalling modulation and coding scheme (MCS) of the radio frame is used.
