Problems solved by technology

[0021] Although the above prior art can obtain streaming media services for mobile terminals, in actual 3G methods, different mobile terminals can have different maximum available bandwidths, such as 144Kbps, 256Kbps, 384Kbps, etc. There are files with different stream rates, such as 120Kbps, 240Kbps, 360Kbps, etc.
Therefore, when the mobile terminal uses the existing technology to use the streaming media service in the 3G network, a file with a code rate of 240Kbps may send a data file to a mobile terminal with a bandwidth of 144Kbps. Since the mobile terminal does not have enough bandwidth to receive the data file, the streaming media service Unable to play normally in the mobile terminal

Embodiment Construction

[0067] The core of the present invention is to report the maximum receiving bandwidth obtained by the mobile terminal through negotiation to the controller end by the wireless application protocol WAP gateway; the controller end determines the data that the server end can send to the mobile terminal according to the maximum receiving bandwidth; Select and load required data from the data determined by the controller to be sent to the mobile terminal.

[0068] Specifically speaking, the core of the present invention is that the wireless application protocol WAP gateway reports the maximum receiving bandwidth allocated to the mobile terminal to the controller; the controller determines the data that can be sent to the mobile terminal according to the maximum receiving bandwidth, and the mobile The terminal selects and loads the required data from the server through the controller; when the file is loaded, the bandwidth required for the code stream rate of the file sent by the ser...

Abstract

This invention provides a data transmission method and a system between mobile terminals and server ends including: a WAPGW reports to the control end that the radio network negotiates with the mobile terminal to get the largest receiving bandwidth, the controller end determines data to be sent to the mobile terminal based on the maximum receiving bandwidth and the mobile terminal selects from the data to be sent to the mobile terminal and loads the necessary data.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data transmission method and system between a mobile terminal and a server. Background technique [0002] The mobile streaming media service is an online audio and video dynamic multimedia content service provided by mobile operators to mobile terminal users through mobile networks and fixed broadband networks. Since this service needs to provide audio and video data services for mobile terminals, it requires high network bandwidth. [0003] With the advent of the 3G era, the 3G network can provide larger bandwidth for mobile terminals to meet the bandwidth requirements of streaming media services. [0004] The existing 3G mobile terminal accesses the mobile streaming media service, and its service implementation process can generally be divided into the following steps: [0005] Mobile terminal Packet Data Protocol (PDP) activation; [0006] The mobile termina...
