smpp

The smpp protocol is an open industrial standard protocol. It provides flexible data communication interfaces for Information Centers and short message system application terminals during text message data transmission. The information center has short message center smsc gsm Unstructured Supplementary Service data. server ussd and other types of short message system applications include the WAP Proxy Server email gateway and some other information ga

, target number, and encoding method. In PDU mode, three types of codes can be used to send Short Messages: 7-bit, 8-bit, and 16-bit (ucs2. In the gsm_03.40 specification, the length of an SMS is defined: 140 characters: 8-bit encoding 160 characters: 7-bit encoding 70 characters: 16-bit encoding Generally, there are two solutions for ultra-long text messages: one is to send multiple separate text messages, so that the mobile phone will receive multiple messages, second, multiple messages are se

short message center (SMSC) and the service provider (SP). It provides a secure and fast channel for data exchange between the two entities. The gateway and the Short Message center use the SMPP protocol (Short Message Peer to Peer) and the SP use the CMPP protocol (China Mobile Peer to Peer, China Mobile Peer protocol ), therefore, the short message gateway must complete protocol conversion, billing, routing, security, network management, and other

The purpose of heartbeat detection is to confirm that the current link is available, that the other person is alive and can receive and send messages normally.

Preliminary knowledge has been rarely seen how many people use PHP socket module to do something, probably everyone positioning it in the context of scripting language, but in fact, PHP socket module can do a lot of things, including doing ftplist,http post submission, SMTP submission, Group packages and carry out special message interactions (e.g. SMPP protocol), WHOIS queries. These are the more common queries. In particular, the PHP socket ext

decoders have been described in detail, so let's learn about the last common decoder-lengthfieldbasedframedecoder.Most protocols (private or public), the protocol header carries a length field that identifies the body of the message or the length of the whole packet message, such as SMPP, HTTP protocol, and so on. Because of the universality based on the length decoding requirement, and in order to reduce the difficulty of the user's protocol develop

What is a socket? A socket is an intermediate software abstraction layer that the application layer communicates with the TCP/IP protocol family, which is a set of interfaces. In design mode, the socket is actually a façade mode, it is the complex TCP/IP protocol family hidden behind the socket interface, for the user, a set of simple interface is all, let the socket to organize data to meet the specified protocol. It has been very rare to see how many people use the PHP socket module to do so

significant threat to system reliability.From the technical aspect, to solve the link reliability problem, we must periodically check the validity of the link. At present, the most popular and common practice is heartbeat detection.The heartbeat detection mechanism is divided into three levels:1) The heartbeat detection at TCP level, that is TCP's keep-alive mechanism, its scope is the whole TCP protocol stack;2) The heartbeat detection of the protocol layer, mainly exists in the raised here co

PHP Socket Programming Detailed This article mainly introduces the PHP socket programming detailed, the need for friends can refer to the following 1. Pre-knowledge It has been very rare to see how many people use the PHP socket module to do something, probably everyone put it in the context of scripting language, but in fact, PHP socket module can do a lot of things, including do ftplist,http post submission, SMTP commit, Group packages and make special message interactions (such as the

and the connection needs to be closed and re-established.The specific Heartbeat message format, as well as the sending interval, and the number of times the Heartbeat message is not received, the link is considered abnormal, and whether the data department counts as a heartbeat message (if some systems receive a packet, the heartbeat timer is cleared, which is equivalent to a packet in the system as a heartbeat message). Both Ends Need to negotiate. For example, the

the token. For example, the customer can use the Web tracking tool to write messages and send messages to Domino everyplace SMS.The recipient selected in the user name list. Administrators can set up this website, and users can use it easily, featuring both privacy and convenience. Domino everyplace SMSSupports accept, TCP/IP, and X.25 packet forwarding. When the instance is confirmed, the information is sent to the data service, and main telephone channels (such as GSM, TDMA, CDMA, a

as a heartbeat message (if some systems receive a packet, the heartbeat timer is cleared, which is equivalent to a packet in the system as a heartbeat message). Both Ends Need to negotiate. For example, the smpp protocol used by GSM to connect Short Message Centers with other network entities requires a persistent connection. Therefore, short-and-short connections are just a concept of Short-and-short connections. They use common socket functions and
