Problems solved by technology

However, for the transmission of the tightly coupled LTE offloaded to the WLAN network, the existing technology does not provide a calculation scheme for the delay time difference of the transmission between the networks, so the delay time difference of the transmission between the networks cannot be known

Abstract

A method and device for acquiring transmission delay between access technology networks. The method comprises: a terminal receives a data packet from a first access technology network and transmitted by a second access technology network, and acquires first time information when the data packet is added to the first access technology network from the received data packet; and calculate, according to the acquired first time information and second time information about the first access technology network when the terminal receives the data packet, information about transmission delay of the data packet. The technical solution of the present invention is capable of acquiring the transmission delay between access technology networks, thereby providing a technical guarantee for preventing the problem of transmission delay of data units and a queuing phenomenon.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for acquiring transmission time delay between access technology networks. Background technique [0002] With the continuous evolution of wireless communication technologies and standards, mobile packet services have been greatly developed, and the data throughput capability of a single terminal has been continuously improved. Taking the Long Term Evolution (LTE, Long Term Evolution) system as an example, it can support data transmission at a maximum downlink rate of 100 Mbps within a 20M broadband. In the subsequent enhanced LTE (LTE Advanced) system, the data transmission rate will be further improved, and can even reach 1Gbps. [0003] The expansive growth of terminal data traffic has made the existing network resources gradually overwhelmed, especially when the new generation of communication technologies (such as 3G, LTE) cannot be widely dep...
