| 英文摘要: |
| Traffic characteristics of several typical instant messager services under certain scenarios are firstly analyzed, based on real-time data collected in the commercial mobile network. Then criteria for the evaluation of the efficiency of the mobile network for the transmission of packet services are proposed in both transport layer and physical layer over air interface. The transmission efficiency of IM services is evaluated and compared under the proposed criteria. Furthermore, a so-called smart resource adaptation algorithm is verified in the effectiveness of improving the wireless transmission efficiency. Finally, improvements to the smart resource adaptation are proposed to further improve the wireless transmission efficiency, and its effectiveness is verified by the calculations. |
