Network information-distribution method and device for transmitting information utilizing information-exchange relationships among users. Information is transmitted from user 1 to all or a portion of user 1's buddies, e.g., users 12 and 13. Next, having received the information, users 12 and 13 then forward the information to their respective buddies. The information is forwarded, for example, to users 211 and 212 registered on user 12's buddy list 21. Likewise, the information is also transmitted to the user group registered on user 13's buddy list 22. By repeating this, buddy lists expressing information-exchange relationships among users are utilized to distribute the information to great numbers of persons.

This is a technique storing and updating the data of electronic map. In accordance with the map factor ID, it can store map data and filter the date downloaded in order to accomplish the electronic map's download of dynamic increment and the update. The user can rapidly download the data of electronic map relevant to the course this time through data service end of map and get the convenience of dynamic navigation. The update of dynamic increment can make electronic map hold the newest mode all the time and can improve the accuracy of accounting navigation course greatly. As the map data during downloading and updating course is filtered, it can avoid the retransmit of data and abate the communicating quantity of updating and save the time and expense of communication.

The invention relates to the areas of internet technique and satellite broadcast technique. It is composed of master station, multi passive station, and communication unit used to connect the master station and the passive station. The master station is a computer having an integrated system, background database and firewall. The integrated system provides editing and sending functions of networking school. The passive station consists of multi computers connected each other through local area network. One of the said computer is as a server connected to communication unit. The management information system and database of the passive station, and firewall is installed on the server station. Other passive stations connected to the server of passive stations through local area network of passive stations provides for logging user to use the courseware resources from database of the passive stations. The information resources is transmitted and managed with quasi-synchronous, master-slave style. The invention makes larner living in area where the switch in condition of Internet is poor being able to study through local area network. Thus one side, more students can share the education resources provided through Internet, on the other hand, the provider of the resources realizes effective centralizing management.

The invention provides a shared link protection method, a node and a shared link protection system, which relate to networks with ring network structures and solve the problems of high data processing overhead, wasting of protection resources and low bandwidth reusability in a shared link protection process. The method comprises the following steps of: when a terminal node of a shared link detects the shared link fails, acquiring the priority of at least one currently available protection channel; selecting the protection channel with the highest priority from the at least one protection channel as a service protection channel; and switching service data on the current shared link onto the service protection channel for transmission. The technical scheme provided by the invention is applied to the networks with the ring network structures.

The invention relates to an engineering equipment information management system and method using a communication terminal installed on the engineering equipment. For this reason, the construction equipment information management system of the present invention is characterized in that it includes: a control server that manages information on construction equipment; a memory unit that stores operating information of construction equipment when the construction equipment is turned off; and if there is a request for prescribed information from the control server, Then the corresponding information is read from the memory unit and transmitted to the communication terminal of the control server.

The invention discloses a method and a system for reducing redundant message retransmission of a radio link control layer, which are used for solving the technical problem that after an RLC protocol entity is rebuilt, the transmitting end transmits the redundant message repeatedly which is confirmed to be received by the receiving end to cause the resource waste. By utilizing the characteristics that the RLC protocol layer can previously predict whether the rebuilt is happened or not, the receiving end RLC protocol entities which belongs to the confirming mode of the same terminal try to senda status message to the transmitting end before the RLC protocol entity receives the rebuilding instruction, the receiving end RLC protocol entity deletes the massage which is confirmed to be received by the receiving end according to the status report before the transmitting end RLC protocol entity receives the rebuilding request, and the message is not transmitted repeatedly after the rebuilding, so the retransmission of the redundant message can be reduced, and the empty expenditure can be reduced.

The invention relates to the technical field of database application, and discloses a distributed data synchronization system and method. In the invention, the distributed data synchronization system comprises a master server station and a plurality of sub server stations; all the sub server stations are respectively in communication connection with the master server station; the master server station is a data sending end; the sub server stations are data receiving ends; or, the master server station is the data receiving end; the sub server stations are data sending ends; the distributed data synchronization method comprises the following steps that the data sending end sends all data to be synchronized to the data receiving end in real time according to a pre-configured data format, wherein all the data to be synchronized include a plurality of data items; the data receiving end receives data from the data sending end in real time; the original data to be synchronized are covered by the received data; therefore, the data are updated in time; pressure balance is realized; requirements to the server are reduced; and the cost investment of the server is reduced.

The present invention provides a method and a system for reducing redundant message retransmission in the Radio Link Control (RLC) layer, which are utilized for solve the technical problem of air interface resource waste caused by repeatedly transmitting the redundant message that the receiving end has acknowledged after RLC protocol entity reestablishment. Before the RLC protocol entity receives a reestablishment instruction, every Data Radio Bear (DRB) belonging to the User Equipment (UE) attempts to send a status report to the transmitting end. The transmitting end deletes the messages that have been acknowledged before receiving a reestablishment request and does not retransmit these messages any more after reestablishment is completed to reduce the redundant message retransmission.
