A measurement system and method suitable for TD-LTE network RRC state machine

Abstract

The invention discloses a measurement system and method suitable for a TD-LTE network RRC state machine and belongs to the technical field of mobile communications. The measurement method comprises the steps of presetting the rule of a server sending a data packet to a mobile terminal, recording the one-way time delay of the data packet and calculating the RRC state switching time parameter of the mobile terminal. The measurement system comprises the mobile terminal and the server both for measuring the time delay; TCP connection is established between the mobile terminal and the server side, and the clock of the mobile terminal and the server side is calibrated by virtue of GPS or NTP clock synchronization. According to the measurement system and the measurement method, network design and resource distribution are optimized and a good use platform is provided for the user of the mobile terminal. Furthermore, the measurement system and the measurement method are capable of providing reliable theoretical support for mobile terminal application developers and finding out the influence of applications on the energy consumption of the terminal in the data transmission process, thus assisting to optimize the data interaction process in the development process; as a result, the network transmission quality can be improved better.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a measurement method and system suitable for RRC state machines in TD-LTE networks. Background technique [0002] TD-LTE is the English abbreviation of Time Division Long Term Evolution (Time Division Long Term Evolution), which is a communication technology and standard based on 3GPP LTE (Third Generation Partnership Project Long Term Evolution technology). Such as figure 1 As shown, in the flat TD-LTE network, the eNodeB (evolved NodeB) network element integrates the NodeB and RNC (Radio Network Controller) of the UMTS network. Among them, RRC (Radio Resource Control Protocol) is implemented in the RNC. The RRC protocol is responsible for the establishment and release of the wireless data link between the mobile terminal and the base station, and maintains an RRC state machine on each mobile terminal device. The state The machine is responsible for managing the state of ...

Problems solved by technology

[0007] However, the inventors have found that the existing measurement methods have the following problems: (1) Compared with the 3G network, the LTE network, because of the existence of the discontinuous reception mechanism, causes this method of actively measuring the round-trip delay from the mobile terminal to be Causes the RRC state to promote to the connected state, unable to measure the discontinuous period of the downlink monitoring channel in the idle state in the LTE network and the size of the activation period in the discontinuous period

(2) In the process of measuring round-trip delay, this method does not take into account the difference in transmission delay between large-byte data packets and small-byte data packets, which will lead to inaccurate RRC state machine parameter measurement results
