Short Message Platform System Design And Realization

With development of communication technology based on internet, the cell phones become widely to be used in daily life. SMS plays second most important role next to talk. Therefore, operators increase SMS services to make more profit.Cell phone users not only receive advisement, notes and information from operators, but also are able to send messages to order, apply the services that they need.The paper in detail describes the system design and the realization, and related background knowledge.The SMS platform system has experienced the developing process which grows out of nothing, gradually consummates, the overall system is from beginning to end independently designed, coded and realized by the author, and continues to consummate.The SMS platform system realizes to communicate with ISMG, dynamically treats with multiple operations received from service interfaces, by this way, the service interface can be used with high efficiency.This system is based on CMPP (China Mobile Peer to Peer) agreement 2.0 (which origins from TCP/IP), UNIX operation system, C language, ORACLE database, via IPC to manage operation process. It can deal with multiple connections with ISMG at same time, does not need to run an independent operation for a single ISMG. For dynamic operation, every received operation is run as an independent program.Embedded self probe system can minor operation system status in real time to make sure the stable run.System is also suitable for advisement to cell phone users via ISMG to provide information source service, which means it will have widely future application. The paper describes the short message information service development survey, the short message gateway system composition, and network structure of the net equipment in the entire short message information service system.The paper describes the SMS platform system design and the realization in the view point of SP (Service provider), favors to the software realization.First introduces the related background knowledge, including CMPP communication protocol, socket communication technique, asynchronous signal mechanism, and IPC (Interprocess Communication) mechanism.From the shallow to the deep, carefully outlined the SMS platform system each constitution element by the abundant way:Short Message PlatformInteracts with the short message gateway by asynchronous communication pattern, as the only interface with the gateway, it realizes the unified receiving and dispatching operation of up and down short message.Dispatch PlatformUnified dispatches multiple services which the service port accepts, realizes effective duplicate uses of the service port.Accept PlatformIn manner of long connection to the data pool, service accepting is accomplished together by dispatches platform and accept platform.Send PlatformReads records from the database, saves to message queue with the type of to be send, reads the reply from the queue, and logs in the table.Proxy PlatformIn order to realize the short message sending function (short message warning, broadcast and so on) on other hosts in the local network, we can deploy a set of proxy platform on the host with an authentication IP. All the constitution elements cooperate with each other, constitutes an organic overall short message platform system.The paper elaborates the related realization main point of each constitution element, has the very high application value.
