Efficient periodic location reporting in a radio access network
A user equipment (UE) communicating with a radio access network (RAN) sends to a network entity (e.g., an MSC/SGSN) a request for periodic reporting of the UE location to a client entity. After the request is approved, the MSC/SGSN sends to the RAN signaling to initiate periodic location reporting for the UE. The RAN may request a positioning center (e.g., a SAS) to send assistance data to the UE. The RAN may coordinate and control the periodic location reporting or may pass the control over to the positioning center. For each location reporting, the UE sends location information (e.g., measurements made by the UE or a location estimate computed by the UE) to the RAN. The SAS computes a location estimate if the UE sends measurements. The RAN then sends the location estimate for the UE to the MSC/SGSN, which forwards the location estimate toward the client entity. |

Semiconductor device and method of manufacturing the same
A gate insulating film of a conventional semiconductor device is subjected to dielectric breakdown at a low electric field strength and thus its service life is short. This is because since the size of the asperity of at least one of a semiconductor layer-side interface and an electrode-side interface is large and, an electric field applied to the gate insulating film is locally concentrated and has a variation in its strength. This problem is solved by specifying the sizes of the asperities of both interfaces of the gate insulating film. |
