Tetra mobile phone integrating GIS and PDA functions and implementation method thereof

Abstract

The invention relates to a Tetra digit group mobile phone with GIS function and PDA function, used in group communication system, as traffic, etc, wherein it designs personal interface protocol stack program (T-Server) matched its own mobile phone; on one Tetra mobile phone with GIS function, it can realize PDA and Tetra functions; and it develops the GIS function with the integrality advantage of Tetra mobile phone, to guide queue position information share technique, to obtain two new function as displaying the queue member position in GIS geography diagram, and sharing the queue member position information, to real-time position the member; when operating GIS program, by pointing the member point in geography diagram, calling and messaging the member.

Description

Tetra mobile phone integrating GIS and PDA functions and its realization method technical field The invention relates to a Tetra cluster mobile phone embedded with GIS, more specifically, relates to a Tetra cluster mobile phone with GIS function and PDA advantages and its realization method. The handset is an integration between a Tetra trunking handset and a GIS-enabled PDA. Background technique At present, foreign countries are very mature in the construction and application of digital trunking communication systems. Large companies such as Nokia in Finland and Motorola in the United States have developed a large number of trunking communication system products, which have been used in government departments, industrial and mining enterprises, public safety, and rail transit systems in various countries. At home, the government has realized the important role of the digital trunking mobile communication system. On December 28, 2000, the Ministry of Information Industr...

Problems solved by technology

The traditional Tetra cluster mobile phone has a small display screen, simple call content, and monotonous user interface, and it cannot understand the location information of the members of the same group during the cluster call, and cannot locate the location of itself and other members.

And in PDA, can realize the function of basic handheld computer, some PDAs can also realize the function of geographical location information positioning, but most PDAs do not have the function that can make a call, and the PDAs that can make a call are also mostly on the GSM network. The PDA that communicates, but cannot communicate on the cluster network
