20100002696 | Broadcast Content Encapsulation - Components of a transmitted service delivering multiple versions of content are mapped to streams carrying data for those multiple versions. The data streams are encapsulated into User Datagram Protocol (UDP) packets; the UDP destination port fields of the packets are given component-identifying values. A user equipment (UE) receiving the transmitted service identifies desired components based on the UDP destination port field values. The UE further encapsulates desired component UDP packets into Internet Protocol (IP) packets, and may assign component-identifying values to fields of the IP packets (e.g., the IP source address and/or IP destination address). | 01-07-2010 |

20100113021 | Association of Network Cells with Location Information - Aspects of the invention provide methods, apparatuses and computer media for providing cell location information in a digital broadcasting system. A mobile terminal uses the cell location information to form a preliminary handover candidate list. A mobile terminal receives reference coordinates for a reference cell, displacement coordinates for a current cell, and displacement coordinates for neighboring cells over a wireless channel. The mobile terminal consequently determines the locations of the current cell and the neighbor cells based on the coordinates. The mobile terminal determines a range distance for the current cell and includes a neighboring cell in a handover candidate list when the neighboring cell is within the range distance, where the range distance is based on an estimated maximum radius of the current cell and optionally on a cell coverage offset. The handover candidate list is further sorted based on distances of the handover candidates from the current cell. | 05-06-2010 |
