Embodiment Construction

[0059] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0060] The invention discloses a bandwidth allocation method for fast buffering of streaming media applications with a single base station and multiple users, aiming at minimizing the average buffering time of mobile terminals in a mobile cellular network. The agent of the streaming media application fast buffering bandwidth allocation algorithm is deployed between the base station and the core network of the cellular network. By collecting parameters such as the amount of data requested by the mobile terminal, signal strength, and user streaming data consumption rate, the bandwidth resources of the base station are allocated. Allocation, under the premise of ensuring fairness and improving bandwidth utilization, decides the bandwidth that each terminal should obtain. Its specific deployment and operation methods are as follows: figure 1 As sho...

Abstract

The invention discloses a bandwidth allocation method for stream media application rapid buffering, which is used for a scene with a single base station and multiple users in a mobile cellular network. In the scene, channel competition occurs among multiple users to result in data transmission waiting and video standstill. According to the invention, a bandwidth allocation agency is deployed between the base station and a core network of the cellular network, and the bandwidth allocation agency collects information periodically such as service bandwidth of the network stream media application, signal intensity information of each user, video playing speed of each user and stream media data size requested by users; when mobile users in the network request for stream media data, the agency runs a bandwidth allocation algorithm of the stream media application rapid buffering, and performs allocation of the stream media bandwidth for stream media users in the cellular network. Therefore, all the users can play videos smoothly, buffering time and standstill of the videos is reduced, and user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of bandwidth resource allocation of streaming media applications in mobile cellular networks, and in particular relates to a bandwidth allocation method for fast buffering of streaming media applications. Background technique [0002] At present, streaming media applications such as PPLive and Youku are becoming more and more popular. With the rapid development of wireless access technologies such as 3G and LTE, users are more and more fond of watching online videos on buses and subways. According to the Cisco Network Index Research Report in 2014, the traffic of streaming media applications has already accounted for 53% of the total network traffic, and it is expected to reach about 69% by 2018. Therefore, it is very necessary and urgent to improve the user experience of the user when watching streaming video. [0003] In the mobile cellular network, the index to measure the application of mobile streaming...
