Embodiments of the present disclosure provide methods and apparatus for group content delivery. A method in a communication network which comprises the content provider node and a broadcast-multicast service node, wherein the content provider node needs to deliver a message to a group of user equipments via the broadcast multicast service node. The method comprises obtaining one or more group identifiers. The method further comprises sending the one or more group identifiers to the broadcast-multicast service node.

Method and apparatus for group content delivery

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.

Enabling a dynamic adaptive streaming over HTTP player to fetch media segments from a network

A method of enabling a Dynamic Adaptive Streaming over HTTP, DASH, player to fetch media segments from a network, wherein said method comprises the steps of receiving, by a DASH Aware Network Element, DANE, middleware, from said network, a manifest, wherein said manifest comprises a representation base Uniform Resource Identifier, URI, for indicating a location to said DASH player for fetching said media segments, a default representation base URI which is available in a default mode for fetching said media segments from a default content delivery network, CDN, a secondary representation base URI which is available in a secondary mode for fetching said media segments from a secondary CDN, transmitting, by said DANE middleware, said manifest to said DASH player, transmitting, by said DANE middleware, to said DASH player, a ManifestModificationCommand message, wherein said ManifestModificationCommand message comprises one or more representation base URI's of any of said default representation base URI and said secondary representation base URI that are to modify a representation base URI in said manifest.

Method, a user equipment and a computer program product for enabling a dynamic adaptive streaming over HTTP, DASH, player to fetch media segments from a network

A method is described that is executed by a computer system implementing a hypertext transfer protocol (HTTP) to enable serving media files by streaming over HTTP. The method is constructed to enable serving media files that are segmented from multiple sources using switch access points defined in a switch access point (SAP) file. The SAP files define transition points in the serving of the media files between different media file sources. The method includes a set of steps such as determining a media meta file or media segment files for a SAP file. The requested media meta file or media segment files are sent to the client. A request for a SAP file is then received from the client. The SAP file request is redirected to a second HTTP server in response to the SAP file indicating the next media segment file identified by the SAP file is not local.

A user equipment node, upon determining that the data loss in a requested file is above, or likely to be above a threshold value, transmits a delivery missing report to a server node indicating that the data loss in the requested file is above the threshold value. The delivery missing report is used by the server node for determining whether or not a multicast file repair procedure should be enabled, based on the number of delivery missing reports it has received from other user equipment nodes. This enables a point-to-multipoint file repair procedure to be enabled sooner, and prevent a flood of point-to-point file repairs.
