Description

A network data transmission method, system and client

technical field

The present invention relates to mobile communication technology, in particular to a network data transmission method, system and client.

Background technique

With the popularization of smart terminals, client applications have increasingly become the mainstream tool for information exchange between enterprise managers and ordinary employees. The choice of network in smart terminals and the interaction speed between clients and servers have become the main obstacles to enterprise information communication. .

Mobile wireless networks include General Packet Radio Service (GPRS, General Packet Radio Service), Enhanced Data Rate GSM Evolution (EDGE, Enhanced Data Rate for GSMEvolution), Time Division Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access), Wi-Fi, etc. When it comes to wireless networks, it has become a consensus that the connectivity and interconnectivity of various networks are poor. In today's fierce competition, good user experience is increasingly becoming a symbol of a successful software. If there are only functions of the software itself and a good interface, but without good data communication speed and customer demand response speed, it will be It is very likely that irreparable damage will be caused.

The communication between the client and the server is mainly the exchange and use of information. At present, the widely used communication methods between the client and the server mainly include socket (Socket) protocol based on TCP/UDP, hypertext transfer protocol (HTTP) or simple object access. protocol (SOAP), etc. Because GPRS and EDGE networks are relatively stable in mobile wireless network standards, but the network bandwidth is not large, TD-SCDMA and Wi-Fi network bandwidth is relatively large, but the network may not be stable, especially when the user is moving Not very stable. From the perspective of network implementation conditions and transmission advantages and disadvantages, Socket requires a specific port, with fast transmission speed, short time, strong real-time performance, high performance, encryption, and strong data security, but the amount of transmitted data is small and needs to be customized. The transmitted data format has relatively high technical requirements for developers. It needs to analyze the transmitted data and convert it into application-level data. Compared with application-level protocols, it increases the amount of development for developers; compared with Socket, HTTP The /SOAP protocol is an interface protocol based on the application level, which is easy to use and has strong fault tolerance, but the transmission speed is relatively slow, and the transmission data packet contains auxiliary application information.

At present, the mainstream android client and server data interaction method is in a single form, either by Socket communication, or by HTTP/SOAP communication, and does not consider the standard of the wireless network. In a large-scale application system, it may involve the transmission of small text, or the transmission of large amounts of data such as pictures, audio and video, etc., but the real-time performance may not be so strong, and many users of the enterprise client are field personnel. . For example, a Chinese patent application document with the application number "201110389055.2" discloses a method for sharing Socket communication services on android, wherein the method includes the following parts: creating a Socket management module, creating an independent thread to run Socket management module, encapsulate the Socket management module as a service component of the system, implement the external interface of the Socket service as an android IBinder object, use the android interface description language AIDL to realize the remote proxy of the IBinder object, and perform inter-process communication and analysis , the patent only uses a single Socket transmission mode, without taking into account the network standard.

A single communication protocol is used in the existing wireless network. In a system application, if only a single transmission method is used without considering the network standard, it is very likely that too much manpower will be invested in the development process of a system. , or in the process of user use, due to the slow information interaction speed between the client and the server and the large data traffic, the perception is not good, so that the business is difficult to promote.

detailed description

Here are the transmission protocols in the wireless network:

Socket protocol: Socket protocol is usually also called socket protocol. Applications usually send requests to the network or respond to network requests through sockets. The connection process between sockets can be divided into three steps: server monitoring, client request, connection confirmation, where,

Server monitoring means that the server-side socket does not locate the specific client socket, but is in the state of waiting for connection, and monitors the network status in real time;

The client request refers to the connection request made by the client's socket, and the target to be connected is the server's socket. For this reason, the client's socket must first describe the socket of the server it wants to connect to, indicating that the server The address and port number of the socket, and then make a connection request to the server-side socket;

Connection confirmation means that when the server-side socket monitors or receives the connection request of the client-side socket, it responds to the request of the client-side socket, creates a new thread, and sends the description of the server-side socket to For the client, once the client confirms this description, the connection is established, and the server-side socket continues to be in the listening state, and continues to receive connection requests from other client sockets.

HTTP protocol or SOAP protocol: HTTP protocol is a communication protocol that allows Hypertext Markup Language (HTML) documents to be transmitted from a Web server to a Web browser. The HTTP protocol is an object-oriented protocol belonging to the application layer. Because of its simplicity, A fast way, suitable for distributed hypermedia information systems; SOAP is a lightweight, simple, XML-based protocol designed to exchange structured and solidified information on the WEB.
