The invention discloses a local scheduler-based multi-point cooperative transmission method, which comprises that: CoMP UE selects K cells from neighboring cells of a local cell as measurement cells and reports the channel state information (CSI) of the local cell and the measurement cells to the base station of the local cell according to MIMO modes and a CoMP types, which are supported by the local cell; the base station of the local cell performs UE scheduling and resource distribution according to the MIMO modes and CoMP types, which are supported by the local cell, and transmits the resources distributed to UE, the MIMO modes and CoMP types, which are supported by the local cell, as well as corresponding resources and CQI difference values, which are recommended to the corresponding measurement cells on the time-frequency resource occupied by the UE, to the cooperative cells; the measurement cells determine if to provide CoMP services and the CoMP types for the UE according to a cooperation message, wherein the measurement cells which provide CoMP services for the UE are cooperative cells; and the local cell and the cooperative cells transmit data for the UE according to the CoMP types.

A space-time-frequency domain based information feedback method, system, user equipment and base station for wireless transmission technical fields is provided. The user equipment measures and evaluates quality of wireless transmission downlinks in MIMO system, obtains rank, precoding matrix index and channel quality indicator information in the wireless transmission downlinks, processes information of the wireless transmission downlink respectively in space domain, frequency domain and time domain by using space selectivity, frequency selectivity and time selectivity characteristics of a channel, and feeds back downlink information to the base station through uplinks by using feedback schemes. The base station optimizes a transmitter according to feedback information from the user equipment.

A wireless device initially has simultaneous circuit switched (CS) and packet switched (PS) services with a non-UMTS network. With the CS and PS services ongoing, the non-UMTS network transmits a HANDOVER TO UTRAN COMMAND message to the wireless device to perform a handover to UTRAN procedure. The HANDOVER TO UTRAN COMMAND message excludes information used for handing over the PS signaling connections to the UTRAN so that only CS signaling connections are handed over. The wireless device receives and parses the HANDOVER TO UTRAN COMMAND message to determine what signaling connections are being handed over. Upon determining that only CS signaling connections are being handed over, a radio resource control (RRC) layer within the wireless device informs an upper layer within the wireless device that no PS radio access bearers or no PS signaling connections are present.

The invention discloses a method and a system for recognizing images, which relate to a method and a system for recognizing static target images by adopting the image recognition technology. The invention solves the problem that the recognition speed is relatively slower in the prior image recognition technology. The method and the system for recognizing the images are characterized in that image information in the identification area and characteristic information in the identification area are stored as template information, then the area to be recognized in the images to be recognized is confirmed by adopting the identification area, then the characteristic information in the identification area is compared with that in the area to be recognized, when the similarity of both characteristic information in the identification area and that in the area to be recognized is in the error range, users consider that the images to be recognized and the target images are mutually matched, so as to realize image recognition, in the recognition process, the characteristic information in the area to be recognized is just needed to compare, the data quantity is less, and the logical reasoning and the mathematical operation of the characteristic information are not required, thereby quickening the speed of image recognition. The invention is mainly used for searching matched images, for example, bill recognition, seal recognition and the like.

A server unit (400) recognizes a travel route search request together with a current position information and a destination information from a terminal unit (300) over a network (200) and searches for a travel route with use of a matching data of a map information. The server unit (400) sends a matching mesh information including a node and link that represent a road corresponding to the travel route and a display mesh information for areas other than the areas represented by the matching mesh information together with the information for the travel route to the terminal unit (300) over the network (200). The terminal unit (300) displays a road based on the matching mesh information and the information excluding the road based on the display mesh information on a terminal display. Thus, the information amount of the map information to be processed can be reduced thereby improving the processing efficiency.

A user request can be reflected in the degree of security of an updated key in quantum key distribution. A sender and a receiver are connected through optical fiber. A quantum transmitter in the sender and a quantum receiver in the receiver carry out basis reconciliation and error correction through a quantum channel, based on a source of a key sent from the quantum transmitter and on a raw key received by the quantum receiver. Under the control of security control sections in the sender and receiver, the amount of information with the possibility of being intercepted that is determined in accordance with a degree of security requested by a user, is removed from the key information after error correction, whereby a final cryptographic key is generated. Secret communication is performed between encryption / decryption sections in the sender and receiver by using the cryptographic key thus updated.
