摘要:
The present invention relates to a method and a web engine. According to a first aspect of the present invention a web engine configured for an ITF (IPTV Terminal Function) such as a STB (set-top-box) comprising an application framework associated with an API enabling display of applications is provided. The application framework comprises a memory for storing at least two applications, wherein the applications are arranged in a hierarchical tree structure in relation to each other. The application framework further comprises an application manager comprising a receiving unit for receiving the event, e.g. a key press, and a controller for controlling the dispatching. The controller may comprise an event wrapper for wrapping and unwrapping the event and a dispatcher for transferring the wrapped event down through the application tree. For each application node (also the root node) the application manager is configured to determine if an event should be processed by the current application.

An access node (e.g., DSLAM) and method for optimizing the distribution of a multicast stream within a hybrid PPPoE/IPoE broadband assess network are described herein. In the preferred embodiment, the DSLAM snoops upstream IGMP messages encapsulated within PPPoE frames, and forwards them transparently towards a BRAS (located in an Ethernet aggregation network). In addition, the DSLAM duplicates the IGMP message and sends the duplicated IGMP message encapsulated within IPoE frames towards the standard Ethernet switches (located in the Ethernet aggregation network). The IPoE encapsulated IGMP message can be snooped by the standard Ethernet switches. This functionality of the DSLAM ensures the optimal multicast distribution by the Ethernet aggregation network.

Methods for scheduling downlink (DL) data on a downlink subframe from a base station directed to at least one wireless terminal in a wireless network are provided. The methods include selecting a control channel element (CCE) region for a physical downlink control channel (PDCCH) carried in a control region of the downlink subframe; determining whether a DL assignment corresponding to the DL data can be allocated on the selected CCE region based on a load imposed on a corresponding physical resource block (PRB) of a physical uplink control channel (PUCCH) of a future uplink subframe that will carry an ACK/NACK response corresponding to the DL assignment; and allocating the DL assignment on the selected CCE region when it is determined that the DL assignment can be allocated.
