On GT800 Digital trunking technology

GT800 is an independent intellectual property rights in China, based on the division multiple access of professional digital trunking technology, through the TDMA and TD-SCDMA creative integration and innovation, for professional users with High-performance, high-capacity cluster business and functions, system stability, sustainable development capacity. Technological innovation embodies the realization and enhancement of cluster characteristics, and has formed dozens of core patents of cluster technology.

1. Group Business

GT800 through the channel sharing, realizes the group service, has greatly enhanced the network resources utilization rate, but also guaranteed other cluster characteristic to realize well, this design may form 3 core technology patents. GT800 group business involving thousands of users, simply by sharing a business channel implementation, calling the initiator to share the uplink channel, and the receiver to share the downlink channel.

2. Quick Call

GT800 's fast connection characteristic is outstanding, the initial call continuation speed is smaller than 1s,ptt speed is less than 500ms, has applied for 5 quick call patents. GT800 according to the specific requirements established by the rapid call, creative call process design, wireless interface enhancement, network optimization and so on, through a number of levels of innovation, to achieve a "through the" function, fully meet the professional users of the rapid call establishment requirements.

3, security enhancements

GT800 has a highly trusted security to meet the needs of public safety and special industries, has applied for 5 key security technology patents, and ultimately is expected to form 15 core patents. GT800 Digital Trunking series core chips and key algorithms are entirely designed by our country independently, the use of domestic independent end-to-end user encryption interface and flow, supporting a variety of terminal encryption module development and key management mechanism, and defined the system and terminal control signaling, to achieve the terminal remote/remote, and so on, for different users, Provide different levels of security.

4. Reliability Enhancement

GT800 provides clustering, fault weakening, and direct through a variety of working methods to ensure the reliability of the system business. GT800 has applied for 13 core technology patents in terms of reliability enhancement. GT800 fault weakening mode provides base station to provide basic group call and point-to-point business capability in the case of transmission broken chain or network equipment failure in the base station coverage area. GT800 is a great innovation in the aspects of Base station switching capability, base station configuration and fault-tolerant algorithm. GT800 the ability to communicate directly between terminals by means of a pass-through work. Even if the professional users leave the service area, can also provide the basic cluster business for professional users, not only improve the reliability of the GT800 to provide cluster business, but also expand the application of professional user cluster business.

5. Cluster Supplementary business

GT800 in the cluster replenishment business, has carried out the fruitful innovation, provides the rich cluster supplementary business, now has applied for the supplementary business Technology patent 5. GT800 defines the information interface and nch of the system and the terminal (including the dispatch station) in the dynamic reorganization, realizes the control Terminal group information and the dynamic reorganization function. GT800 's relay is legally monitored, environmental monitoring, meticulous monitoring, such as cluster business capabilities, involving call control, user priority management, terminal call process design, and other clusters of supplementary services are mainly focused on access management, access control, ground circuit, empty message orders and so on, is expected to eventually form 15 patented technology.

6, GT800 Technology integration

GT800 in TDMA and TD-SCDMA technology integration has made a lot of innovation to ensure the sustainable development of GT800 cluster technology, has applied for core technology patents 5, in the TD-SCDMA cluster capacity enhancement, made a number of breakthroughs, is expected to form the core technology patent 15.

GT800 successfully innovated the TDMA and TD-SCDMA technology in many aspects, formed dozens of patented technology in the cluster characteristic, technology fusion, all proprietary technology is open in the industrial chain, promotes the further expansion of the GT800 industry chain, and promotes the development of China's cluster application.
