Description

A kind ofly reduce method, system, the Access Network of call loss and access terminal
Technical field
The present invention relates to wireless communication technology, relate in particular to and a kind ofly reduce method, system, the Access Network of call loss and access terminal.
Background technology
In wireless communication system, access terminal (Access Terminal, AT) and Access Network (AccessNetwork, AN) Radio Link between mainly is divided into following several state: 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 may initiate at any time connects to set up.
AT under the idle condition generally has following several working method:
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 occurs in connection closed and enters idle condition, the connection closed message of being sent by AT (ConnectionClose) triggers, AN and AT enter slotted mode according to the temporary transient time (SuspendTime) of carrying in the message, promptly enter slotted mode in the time shown in the SuspendTime.Under temporary transient pattern, AN can send paging, and AT can monitor and respond paging, and this pattern is finally to enter 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 enter 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, this situation AT and AN enter dormancy be easy to synchronously control; But in some system, the dormancy period of AT and AN (Period) is variable, and generally is elongated gradually, in this case, AT and AN enter dormancy with time of waking up in case not synchronously on, the situation of call loss then may take place.
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 by reading SC message; Period is the parameter in the configuration attribute, select different Period for use according to different system's absolute times, the value of Period is determined by the value of the SlotCycle of correspondence, is mainly contained 3: the first dormancy period Periodl, the second dormancy period Period2 and the 3rd dormancy period Period3.The concrete value condition of Period is as follows:
Period = Period 1 , t < T 12 Period 2 , T 12 &le; t < T 23 , Period 3 , t &GreaterEqual; T 23
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 l 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 represents 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, 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.
As can be seen, for the specific user who is positioned at certain sub-district, promptly under the situation that Offset is certain and R determines, all of waking up have just been determined constantly basically, again with specific T from formula 1 12And T 23Cooperate, just determined all time slots that wakes up.As seen, AT and AN are to T 12And T 23Calculate can have influence on synchronously AT and AN enter dormancy with wake up synchronous, by T 12And T 23Computing formula as can be known, T 12And T 23Mainly be subjected to the influence of Tc, and T CMainly be subjected to the triggering of some primitive.
Such as, the connection closed message ConnectionClose that starts referring to AN shown in Figure 1 triggers schematic diagram to the primitive of AT and AN, and the issue that the ConnectionClosed indication of (ConnectionClosed) indication and AN is closed in the connection of AT is the driving that is subjected to the ConnectionClose message of AT transmission.AN is 1.5 seconds timer T with triggering duration that a monitoring AT replys after sending ConnectionClose message to AT 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.
The ConnectionClose message format is as shown in table 1, comprise 8 bits message identifier (MessageID), 3 bits close the temporary transient time (SuspendTime) that temporarily enables (SuspendEnable), 0 or 36 bits of reason (CloseReason), 1 bit and the reserved field of variable-length.Wherein, the value of CloseReason field has various ways, the different implication of various value representatives, such as, response (Close Reply) is closed in 001 expression, 010 expression connection error (Connection Error) etc.
For the connection closed that AN initiates, AN sends ConnectionClose message to AT, and the CloseReason field is set to the cause value of other permission except " 001 Close Reply " as the case may be; The SuspendEnable field is changed to 0; This moment, the SuspendTime field was invalid.The CloseReason field that AT replys to the ConnectionClose message of AN is set to " 001 CloseReply "; The SuspendEnable field is changed to 1; The SuspendTime field is made as the absolute time of 0 or 36 bits according to the value of CloseReason field, and the unit of value is 80ms.
Field Length (bit)
Message identifier (MessageID) 8
Close reason (CloseReason) 3
Temporarily enable (SuspendEnable) 1
The temporary transient time (SuspendTime) 0 or 36
Keep (Reserved) Variable
Table 1
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 23If the ConnectionClose message that AN initiates can normally arrive AT, and the ConnectionClose message that AT replys can normally arrive AN, thinks that then AT and AN can enter dormancy and wake-up states synchronously.
But, if deterioration or other reason owing to the wireless link channel quality, cause AT not receive the ConnectionClose message that AN initiates, AN is introduced into idle condition behind the timer expiry of monitoring AT to the ConnectionClose acknowledgement messaging, AT is at monitoring forward traffic channel (ForwardTraffic Channel, FTC) enter idle condition behind the timer expiry again, then AN will calculate T than early triggering of AT 12And T 23As shown in Figure 2, calculate T at AN than early triggering of AT 12And T 23, the dormancy of AN and AT with wake up can not be synchronous situation under, if AT is introduced into slotted mode than AN, so, AN just takes place probably when sending paging, AT is but in the situation of dormancy, thereby causes AT to lose paging.
