Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] as attached figure 1 , The mobile terminal is connected to multiple gateways at the same time. Generally, the mobile terminal supports both CMWAP and CMNET, and some also support WIFI. Since a single gateway alone has the disadvantages of poor stability and idle network resources and terminal resources, the use of multiple gateways can effectively improve resource utilization.

[0035] A thread is started on each successfully connected gateway, and the thread adopts different transport layer protocols according to different gateway characteristics and server characteristics.

[0036] Gateway: at the application layer, CMWAP only supports the HTTP protocol, while CMNET and WIFI support any protocol; at the transport layer, CMWAP supports the TCP protocol, while CMNET and WIFI support both TCP and UDP protocols. Server: Ordinary server refers to the general serv...

Abstract

The invention discloses a high speed downloading method of a mobile terminal connecting multiple gateways and starting multiple threads, which comprises the following steps of: 1. dividing a downloading task into N subtasks according to a certain rule; 2. simultaneously attempting to connecting a plurality of gateways by the mobile terminal and allocating the N subtasks to the connected gateways; 3. starting a plurality of threads for each successfully connected gateway by the mobile terminal and adopting different transport layer and application layer protocols by the threads according to gateway characteristics and server characteristics; and 4. combining the subfiles downloaded by each thread of each gateway connected with the mobile terminal into an object file. The step 3 comprises the following steps of: recording the downloading state parameter of one thread by the successfully connected gateway; using step length 1 to increase the corresponding downloading thread number step by step by each gateway and recording the total downloading speed of the gateway; and if the total downloading speed of the gateway increases along with the increase of the thread number, continuing to increase the thread number, and otherwise, keeping the original thread number.

Description

technical field [0001] The invention relates to improving the downloading speed in a mobile terminal, in particular to a high-speed mobile terminal downloading method for connecting multiple gateways and starting multiple threads. Background technique [0002] With the development of the mobile Internet, the demand for data services has increased significantly, especially the arrival of the 3G era, which has further promoted the development of data services. However, due to the limitations of mobile terminals (low CPU frequency, small memory, limited storage space) and the characteristics of mobile networks, the download speed is far from meeting user needs. The theoretical maximum speed of GPRS is 171.2Kbit / s, while the actual measured downlink bandwidth is about 35Kbps on average. 3G (taking TD-SCDMA as an example) theoretically has a peak downlink speed of 3.6Mbit / s (some say 2.8Mbit / s), but due to the shared bandwidth, the actual measured download speed of TD is around ...
