In step 506,, and received comprising the calculating return information of selected character code in response to the transmission of computation requests information 402." reception " described herein be meant use a communication channel receive data with and/or use transceiver 214, processor 202 and internal memory 204 one or combination in any detecting this data, and this communication channel and the channel that transmits the first calculated solicited message can be identical or different passages.In addition, when carrying out repeatedly examination estimation, in an examination estimation in order to the communication channel that receives a computation requests information with in another examination estimation, can be identical or different passage in order to the communication channel that receives this computation requests information.
At some embodiment, can use one or repeatedly examination estimation to carry out the portable terminal quantity survey (surveying) in the target group.At other embodiment, can then carry out step 508, when this stops with the decision computation cycles, and in operation, step 508 can be made comparisons a present repetitive cycling value and a threshold value, whether has carried out predefined number of times with the decision computation cycles.At this embodiment, at present the repetitive cycling value can be stored in the internal memory that is associated with base station 102 with threshold value, comprises the private internal memory 204 that belongs to (local) or coupled with use input/output unit 208 or interface 210 carrying out long-range (remote) internal memory with base station 102 communications.Under the present situation of repetitive cycling value more than or equal to threshold value, computation cycles can stop.In addition, also can stop computation cycles by transmitting calculating termination message 410.Calculate termination message 410, as computation requests information 402, can comprise a target group identification code.At some embodiment, transmit and calculate after the termination message 410, still can continue to receive character code, in order to detect the selected character code that some portable terminal that does not receive calculating termination message 410 is sent out, it may be because transmit, receive or handle mistake that wherein above-mentioned portable terminal does not receive the reason of calculating termination message 410.At this, can continue to transmit and calculate termination message 410, till in examination estimation next time, not detecting any configuration ranging code.
In step 510, just can estimate the portable terminal quantity that obtains in the target group.At some embodiment, can according to one or repeatedly in the examination estimation received detecting character code quantity carry out this portable terminal quantity survey (surveying), for example: base station 102 will be carried out this step, can comprise r member by the decision target group, r representative be the maximum quantity of the ranging code that detects, can be expressed as:
r＝max(r
1，r
2，…，r
k) (1)
Wherein above-mentioned r
1, r
2..., r
kRepresent the character code quantity that is received in each examination estimation separately.
At other embodiment, can at above-mentioned one or repeatedly computation cycles in the character code that detected carry out maximum likelihood estimation and move, to finish above-mentioned terminal quantity estimation, for example in operation, as mentioned previously, base station 102 can dispose s quadrature ranging code at a calculation procedure, and in response to the computation requests information 402 that carries this s quadrature ranging code or the transmission of its equivalent, base station 102 can receive r respectively in k examination estimation
1, r
2..., r
kIf N represents the actual number of members in the target group, and R
iBe a stochastic variable, represent the ranging code quantity that is detected in the i time examination estimation, target group just can estimate to have n member so, and wherein parameter n can make the following formula maximization:
Pr[N＝n|R
1＝r
1，R
2＝r
2，…，R
k＝r
k] (2)
Be equal to the maximization following formula:
Pr[R
1＝r
1，R
2＝r
2，…，R
k＝r
k|N＝n]·Pr[N＝n](3)
In other words, aforementioned information about the target group number of members be under the condition of unknown or the possible number of members of target group between (meaning when having identical possibility, for each possible n, Pr[N=n] all be identical), the number of members of estimation target group then is equal to find out can make the maximized n of following formula:
Pr[R
1＝r
1，R
2＝r
2，…，R
k＝r
k|N＝n] (4)
Since the ranging code quantity that is detected in k examination estimation is independent of each other, expression formula (4) can be equal to:
C wherein
q pRepresent binomial coefficient
And the ε representative transmits a wrong probability of a ranging code, and for example: ε system is according to through-put power, transmission/reception mistake or other similar physical phenomenon.

Wherein p represents the probability factor of configuration, and by p is made as 1, expression formula (6) will be equal to expression formula (5).
Fig. 6 is the method exemplary flowchart 600 that shows according to the described response one computation requests information of some embodiment.As shown in Figure 6, in step 602, receive selected character code in response to computation requests information 402." reception " described herein be meant use a communication channel receive data with and/or use transceiver 314, processor 302 and internal memory 304 one of portable terminal 106 or combination in any to detect this data.
At some embodiment, be according to a configuration probability factor owing to whether want the decision of the character code that RESPONSE CALCULATION solicited message 402 provided, so can carry out a nonessential step 604 in the case.For example in certain embodiments, can receive a configuration probability factor via computation requests information 402.In operation, a portable terminal can be selected a random number between 0 and 1, then this random number and the probability factor that is received is made comparisons, and whether transmits a character code of selecting with decision.For example at some embodiment, if this random number disposes the probability factor less than this, portable terminal can send out selected character code so, otherwise portable terminal then suspends this examination estimation.
According to step 604,, then in step 606, select a character code that is associated with this code set in case receive a code set and/or determine the condition that this code set satisfy to transmit.The portable terminal of standby or communication mode all can be carried out this and select, and this execution of selecting can be used one or combination in any of processor 302, internal memory 304 and database 306.
In step 608, can see through a uplink resource and transmit computation requests information, for example: as previously mentioned, portable terminal 106a～d can see through the random access channel time slot, range finding passage or other can provide the similar communication channel of the uplink from the portable terminal to the base station, transmits respectively and calculates return information 404a～n.At other embodiment, can use computation requests information 402 contained information that the one uplink passage that substitutes is provided.In addition, transmit to calculate return information 404a～n and can use the through-put power identical, similar or different with computation requests information 402.At some embodiment, calculate termination message 410 if receive, then can finish this program in step 608 back.
In addition, can carry out extra examination estimation, arrive final examination estimation 408 as the second examination estimation 406.In certain embodiments, portable terminal 106a～d can carry out similar function means as shown in Figure 6 in follow-up examination estimation.At other embodiment, but portable terminal 106a～d execution in step 604 determines whether reply a character code with the decision according to last time examination estimation, for example: portable terminal 106a～d can reply one or more character code in previous because of portable terminal, and determined this examination estimation not reply a character code.
