Description

Dormancy with the method for synchronous that wakes up, access terminal and Access Network

Technical field

The present invention relates to wireless communication technology, relate in particular to and access terminal and Access Network dormancy and method for synchronous, a kind of the accessing terminal and a kind of Access Network of waking up.

Background technology

In wireless communication system, access terminal (Access Terminal, AT) and Access Network (AccessNetwork, the Radio Link between AN) mainly is divided into following several kinds of states: init state, idle condition and connection status.Init state refers to catch network and the synchronous process that goes up network after the AT start; Connection status refers to have the connection of opening between AT and the AN, can carry out forward direction and reverse data packet transceive; Idle condition refers to that AT goes up after the network synchronously, the state before connecting, and AN sends the beep-page message to AT under this state, and AT monitoring control channel message and paging etc. are prepared for the business that possibly initiate at any time connects foundation.

AT under the idle condition generally has following several kinds of working methods:

One, continue listen mode, AT is monitoring control channel message constantly, and under this pattern, AN can send the paging to AT, and AT monitors paging and responds paging.

Two, temporary transient (Suspended) pattern, AT is monitoring control channel message a period of time constantly, changes slotted mode afterwards over to.When this pattern generally occurred in connection closed entering idle condition, the connection closed message of being sent by AT (ConnectionClose) triggered, according to entering of temporary transient time (SuspendTime) slotted mode that carries in the message.Under temporary transient pattern, AN can send paging, and AT monitors and the response paging, and this pattern is finally to get into the preceding a kind of temporary transient pattern of slotted mode, and the mode of work and lasting listening mode are basic identical.

Three, slotted mode; Under this pattern, meet some requirements; AT and AN will get into resting state simultaneously, and behind the dormancy certain hour, wake up simultaneously at specific superframe according to respective algorithms, and periodically carry out state transitions in dormancy and between waking up; When AT initiated caller or AT response paging, dormancy and awakening mode just were interrupted.At wake-up states, if AN has the paging of AT, then AN sends paging, and AT monitors paging; If AN does not have the paging of AT, then AT monitoring control channel message.

When AT is operated in slotted mode, only when waking up, monitor paging, so AT and AN dormancy with wake up very important synchronously, to avoid AN and wake up when sending out paging AT in the situation of dormancy, if such AT will lose paging.In system with more, the cycle of AT and AN dormancy all is invariable, and what this situation AT and AN got into dormancy is easy to control synchronously; But in some system, the dormancy period of AT and AN (Period) is variable, and generally is elongated gradually, in this case, in a single day AT and AN entering dormancy do not have synchronously with the time of waking up, the situation of call loss possibly take place then.

Under slotted mode, wake time slot T up and satisfy:

[T+256×R]mod?Period＝Offset，

At all T time slots, AT and AN can wake up, if paging is arranged, then AN sends paging, and AT monitors paging.For ease of describing, the formula that above-mentioned T satisfied is called formula 1 here.

Wherein, R is a fixed value; Offset is the Offset field of the control channel Header of first synchronous packing (SC) of control channel medium access control (MAC) layer; Length is 2bit, and codomain is 0-3, and each sector of this parameter all has one; Generally can not change in case set, AT is known the value of Offset through reading SC message; Period is the parameter in the configuration attribute; System's absolute time according to different is selected different Period for use; The value of Period is confirmed by the value of the SlotCycle of correspondence, is mainly contained 3: the first dormancy period Period1, the second dormancy period Period2 and the 3rd dormancy period Period3.The concrete value condition of Period is following:

$\mathrm{Period}=\begin{array}{}\end{array}\left\{\begin{array}{cc}\mathrm{<figure-callout\; id="1"\; label="Period"\; filenames="H061F4175320060926E000021.png"\; state="\{\{state\}\}">Period</figure-callout>}1,& t<T_{12}\\ \mathrm{Period}2,& T_{12}\&le;t<T_{23}\\ \mathrm{Period}3,& t\&GreaterEqual;T_{23}\end{array}\right.,$

That is to say, at t less than T ₁₂In time, calculates as Period substitution formula 1 with Period1 and to wake time slot T up, promptly calculates according to Period1 and wakes time slot T up; At t more than or equal to T ₁₂And less than T ₂₃In time, calculates as Period substitution formula 1 with Period2 and to wake time slot T up; At t more than or equal to T ₂₃In time, calculates as Period substitution formula 1 with Period3 and to wake time slot T up.

Wherein, t representes system's absolute time, T ₁₂And T ₂₃For according to current system time T _CTwo reference times of calculating are called first reference time and second reference time respectively, and concrete value is as follows:

T ₁₂＝T _c+Period1-[(T _c+256×R)modPeriod1]+Period1×[24×(WakeCount1+1)-1]

T ₂₃＝T ₁₂+Period2-[(T ₁₂+256×R)modPeriod2]+Period2×[24×(WakeCount2+1)-1]，

Wherein, WakeCount1 and WakeCount2 are the parameters in the configuration attribute.

Can find out that from formula 1 for the specific user who is positioned at certain sub-district, under the situation that promptly Offset is certain and R confirms, all of waking up have just been confirmed constantly basically, again with specific T ₁₂And T ₂₃Cooperate, just confirmed all time slots that wakes up.It is thus clear that AT and AN are to T ₁₂And T ₂₃Calculate can have influence on synchronously AT and AN get into dormancy with wake up synchronous, by T ₁₂And T ₂₃Computing formula can know T ₁₂And T ₂₃Mainly receive T _CInfluence, and T _CMainly receive the triggering of some primitive.

Such as; The connection closed message ConnectionClose that starts referring to AT shown in Figure 1 to the primitive of AT and AN trigger sketch map, and the connection closed message that starts of AN shown in Figure 2 the primitive of AT and AN is triggered sketch map, the issue that the ConnectionClosed indication of (ConnectionClosed) indication and AN is closed in the connection of AT is the driving that receives the ConnectionClose message of AT transmission.AN among Fig. 2 is after sending ConnectionClose message to AT, with triggering the timer T that a monitoring AT replys _CSPClose, and wait for that before timer expiry AT returns ConnectionClose message, if timer expiry is not received replying of AT yet, AN then issues the ConnectionClosed indication, changes idle condition automatically over to.

When AT issue ConnectionClosed indication, AT will be according to current system time T _CCalculate T ₁₂And T ₂₃When AN issue ConnectionClosed indication, AN will be according to current system time T _CCalculate T ₁₂And T ₂₃When AT and AN are in connection status,, think that then AT and AN can get into dormancy and wake-up states synchronously if the ConnectionClose message that AT initiates can normally arrive AN.

But, if owing to deterioration or other reason of wireless link channel quality, and cause AN not receive the ConnectionClose message that AT initiates, so, AT will trigger calculating T according to primitive ₁₂And T ₂₃And AN is not owing to receive the ConnectionClose message of AT; Can only be through periodically monitoring reverse traffic channel (Reverse Traffic Channel; RTC), and after the timer expiry of monitoring RTC finds that AT tears chain open, the forward traffic channel of dismantling again (Forward Traffic Channel; FTC) link is perhaps at T _CSPCloseFTC again dismantles after overtime.AN calculates T like this ₁₂And T ₂₃Time T _CTo calculate T than AT ₁₂And T ₂₃Time T _CLag behind.

The different T of following surface analysis _CHysteresis gets into the influence of dormancy and wake-up states to AT and AN.

Suppose Period1=64, Period2=128, Period3=256, R=3, WakeCount1=1, WakeCount2=2, calculate current system time T below respectively _CDifferent dormancy in=40,50,100,150,200 o'clock with wake figure up.

During Period=64, T={67,131,195,259,323,387,451..., 2883,2947,3011,3075,3139,3203...};

During Period=128, T={131,259,387,515,643,771,899,1027,1155,1283,1411,1539,1667,1795,1923,2051,2179,2307,2435,2563,2691,2819,2947,3075,3203,3331,3459,3587...};

During Period=256, T={259,515,771,1027,1283,1539,1795,2051,2307,2563,2819,3075,3331 ..., 11523,11779,12035,12291,12547,12803,13059,13315...}.

2) calculate T more respectively ₁₂And T ₂₃Value:

T ₁₂＝T _C+Period1-[(T _C+256×R)mod?Period1]+Period1×[24×(WakeCount1+1)-1]＝T _C-[(T _C+256×R)mod?Period1]+Period1×24×(WakeCount1+1)；

T ₂₃＝T ₁₂+Period2-[(T ₁₂+256×R)mod?Period2]+Period2×[24×(WakeCount2+1)-1]＝T ₁₂-[(T ₁₂+256×R)mod?Period2]+Period2×24×(WakeCount2+1)；

T _C=40 o'clock, T ₁₂=3072; T ₂₃=12288;

T _C=50 o'clock, T ₁₂=3072; T ₂₃=12288;

T _C=100 o'clock, T ₁₂=3136; T ₂₃=12352;

T _C=150 o'clock, T ₁₂=3200; T ₂₃=12416;

T _C=200 o'clock, T ₁₂=3264; T ₂₃=12480.

3) calculate T at last respectively _C, satisfy all T time slots of formula 1 accordingly at=40,50,100,150,200 o'clock:

T _C=40 o'clock, T={67,131,195,259,323,387...2947,3011,3075,3203,3331..., 12035,12163,12291,12547,12803,13059...};

T _C=50 o'clock, T={67,131,195,259,323,387...2947,3011,3075,3203,3331..., 12035,12163,12291,12547,12803,13059...};

T _C=100 o'clock, T={131,195,259,323,387...2947,3011,3075,3203,3331..., 12035,12163,12291,12547,12803,13059...};

T _C=150 o'clock, T={195,259,323,387...2947,3011,3075,3139,3203,3331..., 12035,12163,12291,12547,12803,13059...};
