An antenna system includes: a radiating sheet provided with an elastic first fixing portion; an insulating bracket including a bracket body, and mounting portions, a second fixing portion and a first assembling portion; coupling circuit sheets, each of which is provided with a coupling circuit at a single side thereof and fixed in a slide rail of the mounting portion in such a manner that a feeding pin at a bottom of the coupling circuit sheet extends out of the one mounting portion; and a feeding network circuit board. In the antenna system and an assembly method thereof, and a base station array antenna, there is various one-time fixing structures, which makes the assembly to be simple and efficient, and there are few feeding welding points, which is suitable for automatic production.

Antenna system and assembly method thereof, and base-station array antenna

An antenna includes an antenna body, a feeding network board screw-connected to the antenna body, and a feeding spring pin connecting the coupling feeding branch with a feeding network of the feeding network board. The antenna body includes a plastic bracket, an antenna radiating sheet provided on a top of the plastic bracket, and a coupling feeding branch provided on a side portion of the plastic bracket. The plastic bracket is formed into one piece, the antenna radiating sheet and the coupling feeding branch are spaced apart from and coupled with each other. The antenna of the present invention has good consistency, high reliability, is easy to assemble without welding, and has a simple overall structure, low cost and small size, and can be used for 5G large-scale antenna array deployment.

Antenna

An antenna calibration network system, an antenna calibration network and a MIMO antenna are provided, and the antenna calibration network system includes a substrate, directional coupler groups provided on the substrate and arranged in a horizontal direction, and a multi-stage combiner network provided at front ends of the directional coupler groups. A parallel coupled line of each directional coupler extends along a horizontal direction. The multi-stage combiner network includes first-stage combiners arranged at one side of the directional coupler groups, and second-stage combiners cascaded with the first-stage combiner and passing between the two directional coupler groups corresponding to the two first-stage combiners to the other side of the plurality of the directional coupler groups. A space utilization rate of the calibration network board can be improved, a size of the calibration network board can be reduced, and antenna cost can be reduced.

Antenna calibration network system, antenna calibration network and MIMO antenna

A general charging method includes establishing a charging strategy and performing the charging according to the charging strategy. The charging strategy includes at least one priority each of which includes at least one time period and each of the time periods is provided at least one rate segment in each of which there is at least one rate. Performing the charging includes: matching with a corresponding charging strategy upon the time a subscriber uses a service and/or the subscriber's current resource, and determining a charging mode; searching for a corresponding priority; performing the charging according to the charging mode. With such a structure of general charging strategy, the method can satisfy various charging demands and provide generality and adequate expansibility. Also, the method enables subscribers to configure different charging methods as necessary.

General charging method

A method for realizing charging includes setting up mapping relation between service attribute and charging rule acquiring service attribute of the to-be-charged service when it is demanded to charge the to-be-charged service acquiring charging rule of the to-be-charged service according to service attribute of the to-be-charged service, and charging the to-be-charged service according to the acquired charging rule. Also disclosed is a charging system having an acquiring charging rule module and charging processing module. When it is demanded to develop new services or modify charging rules of original services, it can be fulfilled by modifying the service information provided for charging processing module accordingly, thus charging requirements of various services can be satisfied. Charging processing module of charging system is independent of services, so that cost of charging system is reduced, and stability, reliability and versatility of charging system are improved.

Method of implementing account charging and account charging system

The present invention provides a general charging method applicable to a charging system in the communication field, comprising steps of establishing a charging strategy and performing the charging based upon the charging strategy. The charging strategy comprises a plurality of priorities each of which comprises a plurality of periods of time, and each of the periods of time corresponds to a type of rate segmentation and is provided a plurality of rate segments in each of which there are a plurality of rates. The step of performing the charging comprises steps of: searching for the highest priority in the charging strategy; searching for a corresponding period of time in the priority based upon the time a subscriber uses a service, and if found, performing the charging based upon the rate segments in the period of time; when the charging has been completed or the priorities have been searched through, and if there is any usage quantity that can't be charged, recording it and terminating the charging. With such a structure of general charging strategy, the present invention can satisfy various charging demands and provide generality and adequate expansibility. Also, the present invention enables subscribers to configure different charging methods as needed.
