20080304454 | HETEROGENEOUS NETWORK AND METHOD FOR HANDOVER BETWEEN HETEROGENEOUS NETWORKS - A heterogeneous network includes a terminal side and a network side. The network side includes an original PoA and handover candidate PoAs. The terminal side is used to select the handover candidate PoAs, initiate a media independent handover request, terminate a connection with the original PoA, and establish a connection with the handover candidate PoAs. The original PoA is used to terminate the connection with the terminal side according to the media independent handover request initiated by the terminal side. The handover candidate PoAs is used to establish the connection with the terminal side according to the media independent handover request initiated by the terminal side. A method for handover between heterogeneous networks initiated by the terminal side and the network side based on the 802.21 architecture is also provided, which improves the processing of the handover process. | 12-11-2008 |
20080318580 | Method And Apparatus For Power Management In Handover Between Heterogeneous Networks - A method for power management in handover between heterogeneous networks comprising: an MIH layer obtains power information and provides it for an MIH user layer; the MIH user layer determines the handover policy according to the power information. In various embodiments of the disclosure, the MIH layer triggers an event so that the MIH user layer can obtain power information, and select a lower-layer network connection automatically according to the current power status, thus implementing handover; the MIH user layer sends a query request to the MIH layer to obtain power consumption parameters from the network, and selects a lower-layer network connection according to the power consumption and the current power status, thus implementing handover and making more accurate and effective decisions in the handover. | 12-25-2008 |
20090036132 | Method And System For Radio Network Environment Detection And Reporting, And Media Independent Handover Apparatus - A method and a system for radio network environment detection and reporting in a network handover and a media independent handover (MIH) apparatus are provided. The method includes the following: an MIH function (MIHF) at a terminal side initiates a network scan, and generates a parameter report on a radio network environment around the terminal including dynamic information and static information of a scanned point of access (PoA) after the scan is completed; the MIHF at the terminal side sends the parameter report on the radio network environment to an upper layer at the terminal side or to an MIHF at a network side. The method and system support homogeneous and heterogeneous network environments at the same time. | 02-05-2009 |
20090113539 | GATEWAY SYSTEM AND METHOD FOR IMPLEMENTING ACCESS TO VARIOUS MEDIA - A gateway system for implementing access to various media is provided in the invention, and the gateway system includes: a communication media access module, for establishing a communication link with the corresponding media access network; a Media Independent Handover Functions module, for seamless handover between accesses to various media; and a handover decision module, for selecting a target network for the seamless handover. The gateway system may also include an authentication module, for sharing the authentication information of the User Equipment. Two methods for implementing access to various media are further disclosed in the invention. By the provided gateway system and methods, the User Equipment can access various media via the gateway system, seamlessly hand over between accesses to various media and achieve the access to a service network using the shared authentication information. | 04-30-2009 |
20100005183 | Method, System and Apparatus for Converting Media Contents - A method, system and apparatus for converting media contents are disclosed. The method includes these steps: a media conversion apparatus receives a media conversion service request from a media application terminal, where the media conversion service request carries a media content ID and playing capability information of the media application terminal; the media conversion apparatus sends a media content transmission request carrying the media content ID to the content source device; and the media conversion apparatus receives a media content identified by the media content ID from the content source device, converts the received media content according to the playing capability information of the media application terminal, and sends the converted media content to the media application terminal. | 01-07-2010 |
20110063413 | Method and Media Player for Playing Images Synchronously with Audio File - A method and a media player for playing images synchronously with an audio file are provided. The method includes the following steps. Audio file associated parameters are read according to a preset time interval when an audio file is played. Stereoscopic image associated parameters corresponding to the read audio file associated parameters are generated according to a preset first corresponding relation between the audio file associated parameters and the stereoscopic image associated parameters. Stereoscopic images corresponding to the audio file are generated according to the stereoscopic image associated parameters, and the stereoscopic images are played. Through the method and media player, stereoscopic images can be played synchronously when an audio file is played. | 03-17-2011 |
