Abstract: A system, method and node for unambiguous encoding of Physical Downlink Control Channel (PDCCH) channels in a Long Term Evolution (LTE) telecommunications system to remove detection errors. The method includes the step of modifying a size of a circular buffer by excluding at least one coded bit from the circular buffer. The circular buffer collects interleaved bits from a PDCCH payload having a plurality of bits. The PDCCH payload is encoded with a convolutional code. The bits of the PDCCH payload are then interleaved. The interleaved bits are collected into the modified circular buffer. The bits are then selected from the modified circular buffer for transmission.

Abstract: Apparatus and Method for transmitting control message related to a packet call service in an IP multimedia subsystem (IMS) that transmits/receives an IMS control message using a control plane to reduce a delay caused by setting of a user plane in a packet call setup process.

Abstract: A system and a method for secure distribution of digital media content through a packet-based network such as the Internet. The security of the present invention does not require one-to-one key exchange, but rather enables keys, and/or information required in order to build the key, to be broadcast through the packet-based network. The digital media content is then also preferably broadcast, but cannot be accessed without the proper key. However, preferably only authorized end-user devices are able to access the digital media content, by receiving and/or being able to access the proper key. Thus, the present invention is useful for other types of networks in which digital media content is more easily broadcast rather than unicast, in addition to packet-based networks.
