Description
Technical Field
The present invention relates to mobile communication technologies, and in particular, to a method, a system, and a client for transmitting network data.
Background
With the popularization of intelligent terminals, client applications have become more and more mainstream tools for information communication between enterprise managers and common employees, and network selection and interaction speed between a client and a server in the intelligent terminals become major obstacles for information communication of enterprises.
The mobile wireless network includes General Packet Radio Service (GPRS), enhanced data rate GSM evolution (EDGE), time division synchronous code division multiple access (TD-SCDMA), Wi-Fi, and when a wireless network is used, connectivity and connectivity of various networks are commonly known. In the fierce competition, the good user experience becomes more and more a sign of successful software, if only the function of the software and the good interface are available, but the good data communication speed and the good customer demand response speed are not available, the irretrievable loss is likely to be caused.
The communication between the client and the server is mainly the exchange and use of information, and at present, the widely used modes for the communication between the client and the server mainly include a Socket protocol (Socket) based on TCP/UDP, a hypertext transfer protocol (HTTP) or a Simple Object Access Protocol (SOAP), and the like. In a mobile wireless network system, GPRS and EDGE networks are relatively stable, but the network bandwidth is not large, and TD-SCDMA and Wi-Fi networks have relatively large bandwidth, but the networks are possibly not stable, and especially the users are not stable in the moving process. From the point of network implementation conditions and transmission advantages and disadvantages, Socket needs a specific port, has high transmission speed, short time, strong real-time performance, high performance, encryption capability and strong data security, but has small transmission data amount, needs to define a transmission data format by user, has higher technical requirements on developers, needs to analyze the transmitted data and convert the data into application-level data, and increases the development amount of developers relative to application-level protocols; compared with Socket, the HTTP/SOAP protocol is an interface protocol based on an application level, is convenient to use and strong in fault tolerance, but has a low transmission speed, and a transmission data packet contains auxiliary application information.
At present, the mainstream data interaction mode between the android client and the server is performed in a single form, namely, Socket communication or HTTP/SOAP communication, and is not considered from the aspect of the system of a wireless network. In a large application system, small text transmission may be involved, or transmission of large data volumes such as pictures, audios and videos may be involved, but real-time performance is not so strong, and many users using clients of enterprises are field staff. For example, a method for implementing Socket communication service sharing on android is disclosed in a chinese patent application with application number "201110389055.2", wherein the method includes the following parts: the method comprises the steps of creating a Socket management module, creating an independent thread to run the Socket management module, packaging the Socket management module into a service component of a system, realizing an external interface of a Socket service into an android IBinder object, realizing IBinder object remote proxy by adopting an android interface description language AIDL, and carrying out interprocess communication and analysis.
In a system application, if only a single transmission mode is used without considering a network system, too much manpower is likely to be invested in a system development process, or a user has poor perception due to low information interaction speed and large data flow of a client and a server in a user use process, so that the service is difficult to popularize.

socket protocol: socket protocol is also commonly called Socket protocol, application programs usually send requests to the network or respond to network requests through sockets, and the connection process between sockets can be divided into three steps: server listening, client request, connection confirmation, wherein,
the server monitoring is that the server socket does not locate the specific client socket, but is in a state of waiting for connection, and monitors the network state in real time;
the client request refers to that a socket of a client makes a connection request, and a target to be connected is a socket of a server, so that the socket of the client must describe the socket of the server to which the client needs to be connected firstly, indicate the address and the port number of the socket of the server, and then make the connection request to the socket of the server;
the connection confirmation means that when the server side socket monitors or receives the connection request of the client side socket, a new thread is established in response to the request of the client side socket, the description of the server side socket is sent to the client side, once the client side confirms the description, the connection is established, and the server side socket is continuously in a monitoring state and continuously receives the connection request of other client side sockets.
