Description
Technical field
The present invention relates to telecommunication technique field, a kind of GPRS data terminal for field telecommunication.
Background technology
For field work, the guarantee of work is not only in communication guarantee, is also safe guarantee simultaneously, the guarantee of life, and the communication product that therefore reliability is high, stability is strong becomes an indispensable instrument of field worker.
GPRS is the English abbreviation of GPRS (general packet radio service) (General Packet Radio Service), is a kind of new carrying business that developed on existing gsm system, it is therefore an objective to provide the data service of block form for GSM user.GPRS uses the tdma frame structure that wireless-modulated standard as GSM, same frequency band, same burst structure, same frame-skipping are regular and same, and this new Packet Data Channel is the most similar to current Circuit-switched voice service channel.Therefore, existing base station sub-system (BBS) can provide comprehensive GPRS to cover from the beginning.GPRS allows user send under end-to-end packet transfer mode and accept data, without the Internet resources utilizing circuit switched mode, thus provide a kind of efficiently, the wireless packet data service of low cost, be particularly well-suited to that be interrupted, paroxysmal, frequently, a small amount of data transmission.Common GPRS module some limitation in use, it does not has embedded ICP/IP protocol stack, user is needed to provide the support of TCP/IP, that is, need to embed TCP/IP in the master system using CPRS module, this is a complexity and loaded down with trivial details work, sometimes even over the workload of application itself.
Summary of the invention
