Embodiments of the present invention provide a method and device for blind detection and uplink access, a receiver, a transmitter, and a base station, wherein the blind detection method includes: demodulating and decoding data of each user serially from received symbols , wherein the process of serially demodulating and decoding each user data includes: using K L-long sequences generated according to preset conditions, and performing correlation operations with Q combined symbol sequences to generate Q×K symbol sequences, wherein, Each combined symbol sequence in the Q combined symbol sequence contains one or more user symbol sequences, and several symbol sequences that reach the preset demodulation threshold are selected from the Q combined symbol sequence for demodulation and decoding. The user's bit sequence generated by decoding is reconstructed, and the reconstructed symbol sequence is subtracted from the combined symbol sequence to obtain the updated combined symbol sequence, and the updated combined symbol data is used as the next round of demodulation and decoding User data of , where Q, K, and L are all positive integers.

The invention relates to an operator call handling method which comprises the following steps that: when a subsystem of a control center receives a call request from a calling terminal and a called number is an operator service number, the subsystem of the control center routes the call request to a visual queue machine; the subsystem of the control center transmits the related information of thecalling request to a server terminal of a visual traffic management subsystem, then the server transmits the information to a client terminal; the server receives the processing request returned fromthe client terminal, and transmits the related information of the client terminal to the visual queue machine; the visual queue machine establishes a communication link of audio-visual frequency between the visual terminal of the client terminal and the calling terminal. The invention also provides a visual call system of manual scheduling which comprises the subsystem of the control center, a visual call management subsystem and the visual queue machine. The invention carries out call queue management to calls accessing the system through the visual queue machine, and provides proper operator position services for the calls through the visual call management subsystem.

The invention discloses a salt-resistant fracturing fluid thickener and a preparation method thereof, belonging to the field of organic polymer compound preparation. The method includes the following steps: adding salt-resistant monomer, acrylamide, chelating agent, cosolvent, initiator and deionized water into a container for mixing and dissolving, adjusting the pH of the solution to 6.5-7.5; purging nitrogen and deoxygenating for 20-30 minutes; placing the solution in Irradiate under ultraviolet light for 50-80 minutes; take out the rubber block, granulate, dry, crush, and sieve. The invention uses salt-tolerant monomers, polymer stabilizers and acrylamide to initiate polymerization under ultraviolet light, with simple process, rapid response and convenient adjustment. The obtained product has high molecular weight (≥15 million), fast dissolution speed and strong salt resistance (resistant to 50,000 salinity), and has a good application effect in the field of fracturing fluid thickening.

The invention provides an intranet and extranet communication method and system, and the method is applied to an intranet and extranet communication system. The intranet and extranet communication system comprises a first gateway, a second gateway, a strong isolation device and an intranet database, and the intranet gateway is connected with the first address of the intranet database; and the extranet gateway is connected with the second address of the intranet database. Under the condition that the first gateway receives an HTTP request which is sent by the application and is used for indicating the access end to access an opposite end network, the HTTP request is stored in the intranet database; the second gateway writes the obtained request result of a to-be-processed HTTP request intothe intranet database under the condition that the to-be-processed HTTP request in the intranet database is queried; and the first gateway outputs a request result to the application when detecting that the request result of the HTTP request is stored in the intranet database. In the application, both the intranet application and the extranet application have no direct relationship with the intranet database, so that the intranet application and the extranet application are not influenced by database change, and the communication efficiency of the intranet and the extranet can be improved.

The present invention provides a channel allocation method and a central base station for security services in a power wireless private network. The method receives time slot application information sent by a terminal station in a security zone, and the time slot application information includes the services of the terminal station in the security zone. Priority; according to the service priority of the terminal station in the security zone, search for a free time slot in a channel divided into time slots; allocate the free time slot to the terminal station in the security zone that sends the application information for the time slot; The central base station is equipped with an application receiving module, a time slot query module and a time slot allocation information sending module. The present invention effectively reduces the occupation of channel capacity during service transmission, and improves the efficiency of wireless spectrum utilization. It has low cost, flexibility and strong scalability, and realizes independent and fast transmission of service data, thereby completing the transmission of different services. Air interface physical layer isolation improves the security and reliability of business data transmission.

The invention provides a data transmission method of robustness. The method comprises the following steps: generating a data block with the length of X bit by a first communication node, wherein the data block comprises cyclic redundancy check information, and generating N first type sub-data blocks containing X / N bits through the data block, and then generating a second type sub-data block containing X / N bits through a counterpoint bit or XOR mode based on N first type sub-data blocks; respectively forming N transmission sub-data block groups through the N first type sub-data blocks and the second type sub-data block, and transmitting N sub-data block groups at N sending beams. The received second type sub-data block can be used for attempting to recovering the first type sub-data block in error. Through the adoption of the method, device and system provided by the invention, the robustness of the data transmission can be effectively increased to adapt to the service demand of the fifth generation wireless communication system in comparison with the prior art.
