In order to improve the perception of Internet services

this paper proposes a cross-layer optimization method based on TCP.And the TCP establishment delay is divided into two independent processes:wireless TCP delay and core TCP delay.Taking TCP service in a province as a sample

the function relationship between wireless TCP delay and number of users is obtained by polynomial regression algorithm.It is proved that when the number of users is less than 200 and the network performance is stable

the wireless TCP delay is strongly related to waiting schedule time and is not related to the business type.By quantitative analysis

modeling simulation and experimental verification

the paper realizes the optimal allocation strategy of wireless TCP delay is given under the wireless resource management mechanism of the SR scheduling data quantity

DRX Inactive Timer and IBLER.The conclusion has high practical value.
