Concrete, for access phase, terminal need be initiated random access procedure to the base station, and promptly terminal sends random access guiding to the base station; When the Initial Trans of this random access guiding satisfied the power requirement of base station, accidental access response was carried out to the random access guiding of terminal in the base station, otherwise the base station abandons this random access guiding.If terminal does not receive the accidental access response of base station, then need to strengthen the transmitting power (promptly promoting a transmitting power promotion step-length) of random access guiding, and continue to send this random access guiding to the base station with new transmitting power, and the like, until terminal receives the accidental access response from the base station, finish till the access phase.
Repeat to send in the process of random access guiding in terminal, the base station is provided with random access parameters such as the Initial Trans, power ascension step-length of maximum number of retransmissions, the random access guiding of permission for this terminal, and broadcasts in the sub-district; Terminal is initiated random access procedure according to this random access parameter to the base station after receiving the random access parameter of this broadcasting, and being provided with of this random access parameter will directly have influence on the performance that inserts at random; For example, cross when low, will cause the time delay that inserts at random excessive, the success rate that influence inserts at random when the Initial Trans of random access guiding and power ascension step-length; When the Initial Trans of random access guiding and power ascension step-length are too high, will cause interference to the link transmission process of adjacent sub-district, the power consumption of terminal also can be bigger.
In order to address the above problem, the repeating transmission number of times of a kind of base station according to the random access guiding of terminal to report proposed in the prior art, adjustment is carried out random access procedure by terminal according to new repeating transmission number of times and/or retransmission interval to the method for terminal broadcast retransmission number of times and/or retransmission interval; Be the repeating transmission number of times information of base station to terminal, carry out statistical analysis, and calculate the ratio that random access guiding reaches maximum number of retransmissions, the load condition of coupling system, adjust and retransmit number of times and/or retransmission interval, thereby realize the optimization that random access guiding is retransmitted number of times and/or retransmission interval in the sub-district.
In addition, a kind of random access procedure definition performance index that are have also been proposed in the prior art, and the method for random access procedure being estimated according to these performance index, be random access procedure definition AP (Access Probability, access probability), AD (Access Delay, access delay) and ADP (Access Delay Probability, the access delay probability) performance index such as, the base station is according to the relevant information of self statistic and terminal to report, calculate AP or ADP, if AP or ADP are lower than the numerical value of prior regulation, then random access parameter are optimized, and in broadcast channel, upgrade the random access parameter after optimizing.
In realizing process of the present invention, the inventor finds to exist in the prior art following problem:
When adopting the base station to adjust method to terminal broadcast retransmission number of times, the problem that exists comprises: when the ratio that reaches maximum number of retransmissions when random access guiding is higher than threshold value, the transmitting power of random access guiding is lower as can be known, if heighten maximum number of retransmissions, can cause that access delay is excessive at random, if turn down the retransmission interval, can increase the weight of system loading; And need when adopting this method terminal to send the repeating transmission number of times information of random access guiding in this random access procedure to the base station, realize complicated.
When being adopted as the method for random access procedure definition performance index, the problem of existence comprises: through performance evaluation index AP or ADP, be optimized when adjusting inserting relevant parameter at random, and can not optimize accurately and the relevant parameter of access at random; For example, when access performance is relatively poor at random, which utilizes index AP and ADP not to judge to be and insert relevant parameter at random and problem occurred, promptly can not be to carrying out adaptive adjustment with the parameter that access is relevant at random; And when using AP and ADP to carry out parameter optimization, in optimizing process, will be referred to more parameter, and need terminal to measure relevant parameter value, and send to the base station, implement more complicated.

As shown in Figure 2, in conjunction with a kind of concrete application scenarios, the random access parameter automatic optimization method that the embodiment of the invention is proposed is described in detail, and wherein, this random access parameter is the transmitting power Control Parameter that inserts at random; Include but not limited to: the Initial Trans of random access guiding (preambleInitialReceivedTargetPower), power ascension step-length (powerRampingStep), the maximum retransmission of random access guiding (preambleTransMax) etc., in above-mentioned parameter, the power information in the embodiment of the invention in the applied random access parameter is Initial Trans and power ascension step-length.Above-mentioned random access parameter automatic optimization method may further comprise the steps:
Step 201, network equipment are provided with too high threshold value of power and the too high probability threshold value of power.Wherein, this network equipment includes but not limited to RNC (Radio Network Controller; radio network controller), NB (Node B; Node B), base station, network management system (OAM) etc.; need to prove that this network equipment is not limited to the said equipment, all are positioned at the equipment of network side all within protection range of the present invention; for convenience of description, the network equipment in the embodiment of the invention is that example describes with the base station.
Concrete, the detection schematic diagram of random access guiding as shown in Figure 3, abscissa is represented the random access guiding of terminal, ordinate is that the power detection value (Power) that this random access guiding obtains is detected in the base station, or the base station detect the signal to noise ratio that this random access guiding obtains (Signal to Noise Ratio, SNR); This threshold (threshold value) A be for can detect the pairing detection threshold of random access guiding, and when promptly the power detection value that detects random access guiding when the base station was less than A, the base station can't detect this terminal, does not promptly send accidental access response to this terminal; When the power detection value of base station detection random access guiding was not less than A, the base station can detect this terminal, promptly sends accidental access response to this terminal.This threshold value B is the too high threshold value of power, when the power detection value of base station detection random access guiding is not less than B, illustrates that the transmitting power of this terminal will have influence on the transmission situation of adjacent sub-district, for example, the up channel generation of adjacent sub-district is disturbed.
In embodiments of the present invention, this threshold value A and too high threshold value B of power that can detect terminal can be the optional according to actual needs empirical value in base station, and the too high threshold value B of this power can detect the threshold value A of terminal greater than this; For example, A is set to 0.8, and B is set to 1.0.Certainly, be not limited to the base station in the embodiment of the invention and select empirical value according to actual needs arbitrarily, can also select empirical value according to actual needs arbitrarily for Network Management Equipment, and this empirical value is notified to the base station, carry out subsequent treatment by the base station according to this empirical value, repeat no more in the embodiment of the invention.Further, the B value can also be determined according to the A value in the base station, and for example, the B value is set to 1.1 times A value, when the A value is set to 0.8 by the base station, corresponding, this B value is 0.88.
Need to prove that the too high threshold value B of this power can also be adjusted according to the random access parameter of adjacent sub-district and the ambient environmental conditions of this sub-district in the base station; Wherein, above-mentioned process all is that threshold value A and the too high threshold value B of power with this sub-district are that example describes.In the process of the initial configuration or the network operation, by X2 interface random access parameter other sub-districts in network are shared between each sub-district, promptly this sub-district can obtain the random access parameter of adjacent sub-district.Wherein, the too high threshold value B of power of self is adjusted in the base station according to the ambient environmental conditions of the random access parameter of adjacent sub-district and this sub-district, be specially: because the network environment of this sub-district and adjacent sub-district is more or less the same, be that the set too high threshold value of power differs also not too large, what the too high threshold value of the too high threshold value of the power of this sub-district and the power of adjacent sub-district can be provided with is identical or similar, after the too high threshold value setting of the power of this sub-district is finished, after the information that receives from the too high threshold value of adjacent cell power, the base station can be according to the network condition of this sub-district and the parameter information of adjacent sub-district, adjust the too high threshold value of power of this this sub-district, it is identical or similar to make that the too high threshold value of the too high threshold value of power and the power of adjacent sub-district of this sub-district is provided with; No longer encyclopaedize in the embodiment of the invention.
In embodiments of the present invention, the base station need be according to the detection power detection value that random access guiding obtained (wherein, this power detection value can be the performance number of the detected random access guiding in base station, terminal is when the base station sends random access guiding, send with transmitting power, but because can be lossy in the transmission course, the power detection value that makes the base station obtain will be launched the transmitting power of random access guiding less than terminal) surpass the random access guiding number of B value, the random access guiding number that surpasses the A value with the power detection value determines that power crosses high probability, i.e. the too high probability P=N1/N of power; Wherein, N is illustrated in the number of detected all random access guidings in base station in the measurement period; N1 is illustrated in detected all random access guiding numbers that exceed thresholding B in base station in the measurement period.This measurement period is the time (for example, this default time is set to 10 minutes) of presetting on the base station according to the actual needs; Or this measurement period is the default according to actual needs number of times of access at random scope interior (for example, insert number of times at random and whenever reach 100 times, represent a time measurement period), and in addition, this measurement period also can be configured the base station by modes such as webmasters.
In addition, the base station can also be provided with the too high probability threshold value of power according to the actual needs, or is the too high probability threshold value of base station configuration power by modes such as webmasters.When power is crossed high probability greater than the too high probability threshold value of this power, then illustrate the Initial Trans of current random access guiding too high and/or, the power ascension step-length of current random access guiding is excessive; Need carry out optimizing and revising of random access parameter.
Step 202, the base station sends random access parameter with the terminal of mode in network of broadcasting.Wherein, in the use after the network initial configuration is finished, the base station sends random access parameter with all terminals in network, this random access parameter comprises Initial Trans, power ascension step-length, maximum retransmission etc., above-mentioned random access parameter is the optional according to actual needs numerical value in base station, and can adjust at any time.
Step 203, terminal is initiated random access procedure according to this random access parameter to the base station.
Concrete, this terminal is initiated random access procedure according to this random access parameter to the base station and is comprised:
(1) when terminal receives random access parameter from the base station, will send random access guiding to the base station with Initial Trans (carrying) at random access parameter; When the base station can detect this random access guiding (power detection value that this random access guiding obtains is detected greater than above-mentioned threshold value A in the base station), the base station will send response message to this terminal; Otherwise the base station can't detect this terminal, also just can't send response message to this terminal.
(2) whether terminal judges in Preset Time (this Preset Time for optional numerical value) according to actual needs receives the response message from the base station, when the response message that receives in Preset Time from the base station, forwards to (4); Otherwise, forward (3) to;
(3) whether terminal judges has reached maximum retransmission (carrying at random access parameter), when not reaching maximum retransmission, this terminal increases a power ascension step-length (carrying at random access parameter) with Initial Trans, and send random access guiding to the base station with the transmitting power after increasing, continue to carry out (2); Otherwise the random access procedure failure of terminal and this base station repeats no more in the subsequent process embodiment of the invention.
(4) terminal is finished follow-up random access procedure with this transmitting power and base station.
Step 204, the base station is write down respectively and is detected power detection value that random access guiding obtained and surpass the random access guiding number of B value and the power detection value random access guiding number above the A value, and judges whether to arrive measurement period, when arriving measurement period, forward step 205 to; Otherwise, when not arriving measurement period, forward step 203 to, continue to initiate random access procedure according to random access parameter by terminal to the base station.Wherein, this A value, B value and measurement period are all described in detail in step 201, are not giving unnecessary details in this step.
In the embodiment of the invention, the base station can get access to the power detection value that detects this random access guiding, relatively the magnitude relationship of this power detection value and detection threshold value A and the too high threshold value B of power after receiving the random access guiding of self terminal.When this power detection value greater than detection threshold value A, and during less than the too high threshold value B of power, the random access guiding number that then the power detection value is surpassed the A value adds 1; When this power detection value during greater than the too high threshold value B of this power, the random access guiding number that then the power detection value is surpassed the B value adds 1, the random access guiding number that simultaneously the power detection value is surpassed the A value adds 1 (owing to can detect the terminal of this power detection value correspondence, as can be known, this power detection value is greater than the A value).
Step 205, after arriving default measurement period, the base station will surpass the random access guiding number of B value according to the power detection value, and the power detection value surpasses the random access guiding number of A value, obtain power and cross high probability, and judge that whether this power cross high probability greater than the too high probability threshold value of power, when judged result when being, forward step 206 to.Wherein, power is crossed high probability and is that the power detection value surpasses the random access guiding number of B value, and the power detection value is above the merchant between the random access guiding number of A value, and the too high probability threshold value of this power is optional numerical value according to actual needs; Described this power in the above in the step 201 in detail and crossed high probability and the too high probability threshold value of power, no longer encyclopaedized in this step.
Step 206, the power information in the random access parameter is adjusted in the base station, to realize the Automatic Optimal of random access parameter.Wherein, when power is crossed high probability greater than the too high probability threshold value of power, as can be known, Initial Trans in this random access parameter is excessive, and/or the power ascension step-length in this random access parameter is excessive, at this moment, terminal in this sub-district may produce the transmission course of adjacent sub-district and disturb, and the power consumption of terminal itself also can be bigger when the base station sends random access guiding; Be that the base station need be adjusted automatically to the power information in the random access parameter, reducing interference, and reduce the power consumption of terminal adjacent sub-district.
Concrete, the power information that the base station is adjusted in the random access parameter comprises: the base station reduces the Initial Trans of random access guiding; And/or the base station reduces the power ascension step-length of random access guiding.
Further, the base station reduces the Initial Trans of random access guiding, is specially the base station according to the actual needs, and suitable reduction Initial Trans for example, reduces 10% etc. with this Initial Trans; The power ascension step-length that the base station reduces random access guiding is specially the base station according to the actual needs, and suitable reduction power ascension step-length for example, reduces 10% etc. with this power ascension step-length.
Step 207, the base station is broadcast to terminal again with adjusted random access parameter, forwards in the step 203, initiates random access procedure according to this adjusted random access parameter to the base station by terminal.
Wherein, the inventive method can be adjusted each sequence of steps according to actual needs.
As seen, the method that the application of the invention provides, in random access procedure, the random access guiding number that surpasses the B value by the base station record detection power detection value that random access guiding obtained, with the random access guiding number of power detection value above the A value, and when arriving measurement period, surpass the random access guiding number of B value and power detection value according to the power detection value and obtain power above the random access guiding number of A value and cross high probability; And cross at this power that (Initial Trans in the random access parameter was too high, and/or the power ascension step-length is excessive when high probability surpassed the too high probability threshold value of power; Thereby cause interference) to adjacent sub-district, power information in the random access parameter of Automatic Optimal adjustment random access guiding (for example, reduce Initial Trans, and/or, reduce the power ascension step-length), and should be broadcast to terminal again by adjusted random access parameter, initiate random access procedure by terminal according to this random access parameter of having adjusted power information, thereby reduced interference, also reduced the power consumption of terminal adjacent sub-district.
