the PDU (Protocol Data Unit) when the form arrives at the telecommunication system, the PDU is decoded and then perform a series of operations. After the PDU is decoded, the system usually extracts some data objects, which may be a subscriber record, this record is used to determine which operations should be performed in response to the received
There are three control modes for sending and receiving short messages: block mode, PDU mode, and text mode. To use the block mode, the mobile phone manufacturer must provide driver support. Currently, the PDU mode has replaced the block mode, while the text mode does not support Chinese characters. Therefore, for the system's versatility and compatibility with the sending and receiving of Short Messages in
The ddlogic framework focuses on the following points:
Task-Based Task Scheduling
Event subscription and Publishing
PDU communication protocol and package disassembly process
Network Asynchronous I/O TCP/IP persistent connection based on the wsaasyncselect Model
Service Module splitting and interaction between modules through interfaces
Persistent data and a layer of Data listening mechanism based on the data (similar to watch debugged by IDE t
The rules for sending and receiving short messages mainly include GSM 03.38, GSM 03.40, and GSM 07.05. The first two focuses on the technical implementation of SMS (including the encoding method), the latter sets out the DTE-DCE interface standard of SMS (AT command set ). Messages are sent and received in three minutes: Block, text, and PDU. Currently, block is rarely used. text is a plain text method and can use different character sets. Technically
There are some problems with the previous project, such as1 only one connector can handle HTTP requests, and another connector cannot be added to handle HTTPS.2 The closure of the container can only be rough closing the bootstrap.An instance of the server component Org.apache.catalina.Server interface is used to represent the entire servlet engine for Catalina.We use the server because it uses an elegant way to start/shut down the entire system.Here's how the start and stop mechanisms work.

interaction of LDP Hello messages, two LSR (LDP peer) can be used to establish LDP sessions to transmit tag/FEC binding information. when an LSR broadcasts multiple tag spaces to another LSR using LDP, it creates a session process for each tag space. LDP uses TCP to provide reliable transmission services. When multiple LDP sessions exist between two lsrs, each LDP session corresponds to a TCP connection.(2) LDP session maintenanceLDP regularly receives the data unit
Since the API for reading and writing messages is hidden, we need to use the reflection method mentioned in the "learning of Java reflection mechanism " article to get the hidden API.

A simple class library was completed some time ago. Although it can complete sending and receiving SMS messages, the class library is not perfect.For example, the USC2 encoding is used to send an English text message. Each text message can contain up to 70 characters. If 7-bit encoding is used, each message can send 160 characters. This article adds the PDU Encoding Based on the previous class.
Solution: Same as before, only partCode.The
text mode, and at command-based PDU mode encoding, the Siemens 6688 mobile phone supports PDU mode encoding. This encoding method sends the text message body after hexadecimal encoding. PDU encoding can be divided into 7-bit, 8-bit, and 16-bit encoding. 7-bit encoding can contain up to 160 characters, and 8-bit encoding can contain up to 140 characters, 16-bit e
