Description
Technical field
The invention belongs to mobile communication technology fields, and in particular to suitable for the measuring method of UMTS network RRC state machine
And system.
Background technology
Mobile communication technology has obtained widest by feat of characteristics such as its high bandwidth, low time delays in worldwide
Using.As shown in Figure 1, in UMTS (Universal Mobile Communication System), it is (wireless that RRC (radio resource control) is embodied in RNC
Network controller) in, RRC agreements are responsible for the foundation and release of wireless data link between mobile terminal and base station, and each
Maintain a RRC state machine on a mobile terminal device, which is responsible for the state of physical link.Usually,
Mainly there are three states for UMTS mobile terminals：(1) IDLE state：There is no data link between terminal and base station, it is impossible to transmit
Data, and final energy is not consumed substantially；(2) FACH state：One shared data link is assigned to terminal, only props up
The data transmission of low rate is held, consumption energy consumption is relatively low；(3) DCH states：One dedicated data link is assigned to terminal, with
For the data transmission of high-speed.
Having switching between RRC different conditions, there are two types of types：It is that UE is switched from low energy consumption state to high power consumption state respectively
(Promotion) and UE switches (Demotion) from high power consumption state to low energy consumption state.Wherein, state Promotion (is moved
Rise) represent that network interface is transferred to high power consumption state from low energy consumption state, such as from IDLE → DCH or IDLE → FACH → DCH.Shape
State Promotion is triggered by data transfer demands, and the switching of this state is related to the request and distribution of dedicated link, can bring compared with
Big time delay；State Demotion (degradation) represent network interface be transferred to low energy consumption state from high power consumption state, such as from DCH →
FACH → IDLE or from DCH → IDLE.Demotion is triggered by inactivity timer, and any data are not observed in T time
Inactivity timer triggering Demotion is transmitted, wherein T time is otherwise known as the tail time.
The different RRC state machine of different UMTS network operator quotient's possible configurations and switching law and state machine are specific
Parameter is the state machine model of operator's possible configuration as shown in Figures 2 and 3.
In RRC state machine A, for promotion, when mobile terminal is in IDLE state, any data pass
It is defeated all state to be caused to be switched to DCH states.If in FACH state, uplink and downlink datalink queue is more than threshold value, just
DCH states can be switched to；For demotion, when terminal is in DCH states, in T1Do not observe that any data pass inside
It is defeated, mobile terminal state switching FACH state.When in FACH state, T2It is switched in time without data transmission, state
IDLE state.In RRC state machine B, for promotion, if mobile terminal is in IDLE state, there is a small amount of low speed
Data are transmitted, and are switched to FACH state；When the data for needing to transmit are more than wireless data link threshold value, FACH state switching
To DCH states；For demotion, when terminal is in DCH states, T3Interior not have data transmission, state is switched to IDLE
State.
Switching law and state machine design parameter between the RRC state of mobile terminal are configured by operator, can't be led
Dynamic to disclose these parameters, user equipment can not directly acquire above-mentioned parameter, and measure skill currently for mobile-terminal RRC state machine
Art research is less.QianFeng et al. proposes a kind of active measurement side for being suitable for mobile-terminal RRC state machine in a wcdma network
Method actively sends UDP message packet by terminal to server, and then server returns to a UDP message packet to mobile terminal,
Record round-trip delay is measured during this, undergoes certain dormancy time, repeat more than operation.This method can lead to
The changing rule of analysis round-trip delay is crossed, and then completes the measurement to mobile-terminal RRC state switching law.Inventor has found this
The problem of measuring method：(1) during round-trip delay is measured, do not account for send big byte data packet with it is small
Byte data packet causes when calculating mobile-terminal RRC state machine design parameter, meeting in otherness present on propagation delay time value
Cause certain measurement error.(2) such method is not switched to FACH state at the uplink and downlink data link door of DCH states
Limit value measures respectively, causes RRC state machine design parameter incomplete.
