Description

The present invention relates to the field of communications, and in particular to a data transmission method and platform. BACKGROUND OF THE INVENTION The mobile internet service is an emerging service that combines the advantages of mobile networks and the Internet, and can provide users with various types of services such as voice, data, images, and multimedia through mobile terminals. A smart phone is an important part of the mobile Internet business. An application client program that can run a specific function on a smart phone can provide users with personalized, content-related and interactive work applications through interaction with the application server. risk. With the popularity of smart phones, more and more users are accustomed to using their mobile phones to use their daily life, the business they are used to at work, such as mobile QQ, mobile phone mailbox and so on. In the related art, there are long links between terminals, platforms, and application servers, and various signaling and data are transmitted through long links. When the data is large, it will occupy more bandwidth and affect the transmission of other data and signaling. The Always Online Gateway (AOG) platform provides unified messaging channels and simultaneous transmission channels for enterprise services, Internet services, home services, and content providers, facilitating applications and content in a variety of ways, safely and reliably. Extend to the user terminal. The AOG platform provides a unified access point for long-term mobile Internet-based applications, which can provide customers with high-performance, low-latency user experience services, increase user stickiness, and increase business revenue. However, with the massive use of data services in smart phones, some problems have gradually emerged: Compared with ordinary mobile phone users, the application of smart phones generates a large amount of data traffic, which has a great impact on the bandwidth of the entire mobile internet. For example, iPhone users account for only 3% of AT&T users, but consume up to 40% of bandwidth, resulting in poor voice quality services. The implementation of the intelligent terminal is an application to establish a long connection to the application server. Assuming that a smart terminal runs 10 applications, 10 long connections are made to the application server. Since the number of terminals is very large, and each terminal establishes multiple connections, the number of long connections in the mobile Internet is a very large number. This large number of long connections seriously affects the mobile Internet. Network performance. In addition, since each long connection will periodically initiate a link detection packet to detect, resulting in a large number of detection packets in the network. These additional signaling loads allow the mobile Internet network to do a lot of additional wireless channel allocation and creation for this, which can easily lead to dropped calls, inaccessibility, and network congestion. These two questions fully illustrate the current mobile Internet services have many large data transmission requirements, such as mobile phone accessories, video file downloads and so on. And the number of long links between the terminal and the application server is a super-large number. 1 is a schematic diagram of data transmission according to the related art AOG platform. As shown in FIG. 1, for an intelligent terminal (a plurality of application clients running on the terminal), the AOG platform provides a link (such as link 1 of FIG. 1). Transmitting; linking to the application provider (eg, QQ) and the AOG platform (such as link 3 in Figure 1) is provided for use by all smart terminals that use the application. In the related art, the AOG platform converges the number of long connections by installing middleware on the smart terminal. The AOG platform has one long link for each smart terminal, and multiple applications running on the smart terminal share this link. However, this also has problems. At this time, if one of the applications is downloading a large file, it will inevitably occupy a large amount of bandwidth and cause all services of the terminal to be affected.

Wherein, the predetermined threshold is 8k. Embodiment 2 In this embodiment, the implementation process of the embodiment of the present invention is described by taking the data transmission of the AOG platform as an example. In this embodiment, the data transmission process of the AOG platform is modified. When the application server or the intelligent terminal needs to send big data, the intelligent terminal applies for opening a new temporary channel for data transparent transmission by the AOG platform. Thereby ensuring the transmission of big data without affecting the use of existing smart terminal applications. In this embodiment, the structure of the AOG platform based on the big data transparent transmission channel is improved.

The service processing module is mainly responsible for the contract relationship management and authentication of the AOG platform; the link management module is mainly responsible for establishing, maintaining, and deleting links of the AOG platform and the external network element; the message receiving module is mainly responsible for the AOG platform for other network elements. The message receiving, parsing and sending the message to the service processing module; the message sending module is mainly responsible for the message transmission of the AOG platform to other network elements; the configuration management module is mainly responsible for the system external network element configuration and the contract relationship configuration management; the PROXY service processing module is mainly responsible for The link to establish the correct link to the lower-level network element and the link selection when forwarding the message; the PROXY message receiving module is mainly responsible for receiving the large data file of the external network element; the PROXY message sending module is mainly responsible for sending the large data file of the external network element. The PROXY Link Management Module is primarily responsible for the establishment, maintenance, and deletion of links. The PROXY service processing module interfaces with the configuration module interface, the PROXY message sending module, the PROXY message receiving module, and the PROXY link management module; the PROXY link management module interfaces with the PROXY message receiving module and the PROXY message sending module; the service processing module and configuration The management module, the message receiving module and the message sending module interface; the link management module interfaces with the message receiving module and the message sending module. In the embodiment, the data transmission is performed by the following method: Step A: The configuration management module first configures account information of each external network element (including: Internet Protocol (IP), port, etc.), service Information, etc.; each external network element has established a normal service link with the AOG platform; Step B, when the server application end needs to send large file data, send a downlink message to the AOG gateway, and notify the intelligent terminal to initiate a temporary link; Step C, AOG Gateway After receiving the message, the message receiving module sends the message to the service module for routing, and forwards the message to the corresponding intelligent terminal through the message sending module; Step D, after receiving the message that the temporary link needs to be established, the intelligent terminal receives the message Initiating a link establishment request message to the PROXY link management module of the AOG platform; Step E, the AOG link management module forwards the received link establishment request message to the PROXY service processing module; Step F, the PROXY service processing module performs the APPID (application server Marked) business After the authentication, the lower-level network element account is selected according to the APPID route, and the IP and port number information is extracted from the lower-level network element account information to establish a link request to the lower-level network element, and the correspondence between the intelligent terminal link and the lower-level network element link is recorded.

And the 4 bar data stream is forwarded to the PROXY message sending module; Step J, the PROXY message sending module forwards the big data file to the lower level network element; Step K, the application server (smart terminal/independent AOG gateway), after sending the file, The PROXY message receiving module sends a broken link request (ie, a disconnect request;); Step L, after receiving the broken link request, the PROXY message receiving module forwards the request to the PROXY service management module; Step M, the PROXY service management module disconnects the application The server (smart terminal) side link finds and disconnects the smart terminal (application server) side link corresponding to the link, and the temporary transmission big data channel is all closed. In the above method, if the application scenario is that the smart terminal needs to send a big data file, the method may start from step D, and the following process is similar to the process in which the application server needs to send a big data file, but the direction is opposite, and After the big data file is sent, the smart terminal initiates the unlinking. In this embodiment, the big data transmission efficiency is improved, and while the big data file is transmitted through the temporary link, the long link between the original application server, the AOG platform, and the intelligent terminal is used to transmit the other. Services (for example, packets and signaling that do not exceed a predetermined threshold), thereby avoiding the impact of big data transmissions on existing business functions. Embodiment 3 FIG. 3 is a schematic diagram of a system and an external networking according to an embodiment of the present invention. As shown in FIG. 3, the PROXY processing module is newly added to the macro data transparent transmission in this embodiment. The intelligent terminal and the AOG platform still have only one link (such as link A1 of FIG. 3) for performing messaging of multiple application client programs. A link to the AOG platform (such as link A of Figure 3) for the application provider (e.g., QQ) is also provided for use by all smart terminals that use the application. However, for the transmission of big data, this embodiment can transmit by adding a temporary transparent transmission channel (link 1 of FIG. 3) through the PROXY module. Thereby avoiding the impact of big data transmission on existing services. The following describes the process of data transmission in the embodiment of the present invention by taking an application provider server to send a big data file as an example. 4 is a flow chart of a method for establishing a link of a big data transparent transmission channel in an embodiment of the present invention. As shown in FIG. 4, the method includes: Step S401: The application provider sends a notification message (notifying the smart terminal to apply to establish a temporary transparent transmission channel) to the AOG platform. Step S402: The AOG platform receives the request message through the message receiving module, and forwards the request message to the service processing module. Step S403: The service processing module searches the routing table for the link between the smart terminal corresponding to the destination number and the AOG platform by using the destination number in the message; if the matching is successful, the process proceeds to step S405; otherwise, the process proceeds to step S404. Step S404: The smart terminal is not online, and the file cannot be transmitted to the terminal, and the process ends. Step S405: The AOG platform forwards the request for establishing the temporary channel by the application server to the smart terminal through the link; (If the smart phone needs to send big data, it may start directly from step S406;). Step S406: The smart terminal establishes a link to the PROXY link management module of the AOG platform, and sends a link establishment request, where the request carries an application server ID (APPID). Step S407: The PROXY message receiving module receives the request message and forwards the message to the PROXY service processing module. Step S408: The service processing module performs route search through the APPID, and obtains information such as an IP address and a port number of the application provider server corresponding to the APPID; if the route search fails, the process proceeds to the step. S409, the search succeeds in step 4 to gather S410. Step S409: The application does not exist, and the process ends. Step S410: The PROXY service processing module establishes a link to the application corresponding to the APPID and initiates a link establishment request; if the link establishment fails, the process proceeds to step S411, and if the link establishment is successful, the process proceeds to S412. Step S411: The link establishment fails, the PROXY service processing module deletes the link between the AOG and the application server, and the corresponding link between the AOG and the smart terminal, and the process ends. Step S412: The link is successfully established, and the AOG service processing module records the link correspondence between the "AOG and the application server" and the "AOG and the smart terminal". FIG. 5 is a flowchart of a method for implementing big data transparent transmission and link deletion according to an embodiment of the present invention. As shown in FIG. 5, the method includes: the temporary channel link is successfully established, and the application provider server and/or the smartphone application client/AOG heterogeneous platform send a big data file on the established link. Step S501: The PROXY message receiving module receives data from the established link and forwards the received message to the PROXY service processing module. Step S502: The PROXY service processing module searches for the forwarding link number corresponding to the link that receives the data. If the search succeeds, the process proceeds to step S504. If the search fails, the process proceeds to step S503. Step S503: The temporary link is abnormal, the PROXY link management module closes the temporary link that receives the data, the message is sent, and the process ends. Step S504: The PROXY message sending module forwards the data through the found link. Step S505: determining whether the transmission data is a temporary link clear message, if it is a clear message, proceeding to step S506; otherwise, proceeding to step S501. Step S506: The PROXY link management module deletes the sending data link and the forwarding message link corresponding to the link. In the fourth embodiment, in the application process of transmitting the big data file to the end user through the transparent transmission channel (temporary link), the system completes the message processing as follows: In this embodiment, the system networking structure shown in FIG. 3 is still used.

And the mobile QQ and the mobile phone mailbox send and receive messages through the link A1 and the AOG platform; the smart terminal B runs the mobile QQ and the mobile phone normally, and sends and receives messages through the link A2 and the AOG platform; configures the QQ application server account as the QQserver on the AOG platform. , IP is IP1, port number is 6524, and APPID is 13. It is assumed that the QQ server needs to send a QQ to send a large file to the intelligent terminal A. The QQ server sends a temporary channel request message through the link A. After receiving the request message, the AOG gateway routes the terminal number, and sends a temporary channel request to the intelligent terminal A through the link A1. The QQ application on the intelligent terminal A After receiving the message, the link 1 is established to the PROXY link management module of the AOG platform, and a request for establishing a temporary link message is sent; the PROXY message receiving module of the AOG sends the received request to the PROXY service processing module; the PROXY service processing module Through the APPID in the request message is 13, matching to the application server QQserver; and sending a link establishment request to IP1, port 6524; the temporary channel link 1 is successfully established. The QQ server sends a big data file through link 1, and sends a link clear message after the file is transmitted. The link management module of PROXY receives the link clear message and deletes the link 1 sent this time. In the whole process application example in which the end user sends the big data file to the application server through the transparent transmission channel, the process of completing the message processing by the system is as follows: In this embodiment, the system networking structure shown in FIG. 3 is still used, if the smart The QQ application on terminal B needs to send a big data file. The QQ application on the intelligent terminal B establishes a link 2 to the PROXY link management module of the AOG platform, and sends a request to establish a temporary link message; the PROXY message receiving module of the AOG sends the received request to the PROXY service processing module; the PROXY service processing module The APPID is 13 in the request message, and the application server is exposed to the QQserver; and the establishment link request is sent to the IP1 port 6524; the temporary channel link 2 is successfully established. The QQ application on the intelligent terminal B sends a big data file through the link 2, and sends a link clear message after the file is transmitted.
