The Research And Achievement Of Short Message Service In Private Coal Communication Network Based On TD-SCDMA

With the development of wireless communication technology,nowadays,the publicmobile communication network has adopted3G technology with smooth evolution to4G,however,most of coal mine, its underground communication dispatch system is still in thestate of wired communication dispatch and PHS（personal handy-phone system） wirelesscommunication dispatch at home. The communication system based on TD-SCDMA canprovide effectively voice with high quality, high rate data transmission services, remote videosurveillance service and so on. The system offers a great chance for the development ofcurrent coal communication system.According to the situation and problems in the development of private coalcommunication networks, the paper has analysed advantages of the TD-SCDMA applicationin private coal communication networks by comparing with main wireless communicationtechnology. A new designing solution of private coal communication network based onTD-SCDMA has referenced. Then, the paper has described overall and software architecturein private coal mine product.In order to realize TD-SCDMA private network SMS, the thesis proposes the solutionwhich integrates SMSC (short message service center) with core network CS domain inprivate coal mine product. Further research on SMS interface protocol stack hasimplemented.The paper has studied the achievement of SMS and analyzed it from the view ofapplication, protocol stack, and interface relationships. It is focused on the design of signalingprocedures of TD-SCDMA user’s SMS MO and MT, SIP user’s SMS, and mobile stationmemory available information. It is devised the control of SMSM procedures, MO proceduresand MT procedures in great detail, and completed TD-SCDMA user’s SMS programming.Atthe end, the article achieves prosperously softwares explanted，completes the combineddebugging of software and hardware.Experimental result has shown that the new private TD-SCDMA communication facility can achieve effectively TD-SCDMA user’s SMS after integrating the SMSC basic function,simplifying communication facilities and procotols, which provides the theory evidence andapplication solution for future enriching and improving function of the private coalcommunication network.
