Embodiment

To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention Formula is described in further detail.

Various technologies described herein can be used for plurality of communication systems, such as current 2G, 3G communication system and the next generation Communication system, such as global system for mobile communications (GSM, global system for mobile communication), code Divide multiple access (CDMA, code division multiple access) system, time division multiple acess (TDMA, time division Multiple access) system, WCDMA (WCDMA, wideband code division multiple Access) system, Long Term Evolution (LTE, long term evolution) system and follow-up evolution system etc..

In the communication system of the embodiment of the present invention, base station equipment and user equipment can be included.Wherein, the base station equipment It can be used for being communicated with the user equipment.

Fig. 1 is a kind of base station equipment operative scenario schematic diagram.In Fig. 1, the base station equipment includes a base station control Device, the base station controller can manage at least one base station, base station 1, base station 2 and base station 3 as shown in Figure 1, each base station Data interaction between base station controller be present.Each base station can manage at least one cell, as base station 1- base stations 3 manage respectively One cell, i.e. cell 1, cell 2 and cell 3.Cell 1 includes user equipment 1, user equipment 2 and user equipment 3, when certain One user equipment is intended to move into connection status from idle condition, or is in cell forward access state, cell paging state or note The different conditions such as volume area paging state issue when serving row information, can be established and connected by random access procedure and base station 1, Obtain corresponding communication service.Each user equipment and the random access procedure of base station 1 are independently carried out, and base station can be simultaneously Handle the random access request that multiple user equipmenies are sent., then can be again when a certain user equipment is moved to other cells Establish and connect with other base stations, to ensure service quality.

In different wireless communication systems, the base station equipment, which can include, has different parts, for example, In GSM, CDMA or WCDMA system, the base station equipment can include base station and base station controller, and the base station can refer to connect The equipment to be communicated in the air on interface by one or more sectors with the user equipment in networking, for example, can be GSM or The base transceiver station (BTS, base transceiver station) of cdma system, or can also be in WCDMA system Node B (Node B)；Base station controller can be base station controller (BSC, the base station in GSM or cdma system Controller radio network controller (RNC, the radio network) or in WCDMA system controller).The base station can be connected with the base station controller by wired or wireless way, and the base station is by described Base station controller management controls.The user equipment can be the user equipment wirelessly carried out data transmission with base station, Such as mobile phone, possess personal computer of radio communication function etc..In the subsequently further evolution of LTE system and LTE In system, the base station equipment can include evolved node B (e-Node B, evolved Node B), the e-Node B Can have the partial function of base station control, such as the scheduled transmission including paging information；The scheduled transmission of broadcast message；And Set and provide e-Node B measurement etc..

With the quantity that user equipment is required data transmission service and quality more and more higher, intra-cell users equipment is in list It is more and more to the random access request of base station equipment initiation in the time of position, and the data transmission capacity of cell RACH It is limited, easily there is channel congestion, cause random access guiding to send unsuccessful, user equipment and then what is be repeated random connect Enter to attempt, cause the reduction of Stochastic accessing success rate, while further resulted in the deterioration of channel letter energy.

In embodiments of the present invention, the random access guiding that base station equipment is sent according to record to user equipment in cell Confirmation message number, to obtain the loading condition on cell RACH, so to used in user equipment with Machine access parameter carries out Reasonable adjustment.

By taking WCDMA system as an example, user equipment can send random access guiding to Node B, after Node B are received, Confirmation message is sent to user equipment, represents that this random access guiding is sent successfully, Node B record the confirmation message Number, and reported by the cycle to RNC, make comparisons, surpass with pre-determined threshold after being handled by RNC the number of the confirmation message Pre-determined threshold is crossed, adjusts random access parameter.

By taking LTE system as an example, user equipment can send random access guiding to e-Node B, and e-Node B are received Afterwards, confirmation message is sent to user equipment, represents that this random access guiding is sent successfully, e-Node B record the confirmation and disappeared The number of breath, and made comparisons with pre-determined threshold, more than pre-determined threshold, adjust random access parameter.

Before the user equipment can utilize the random access parameter after the adjustment to send Stochastic accessing to base station equipment Lead.Main random access parameter includes, initial power constant (Constantvalue), the Stochastic accessing of random access guiding Leading power ramp step-length (PowerRampStep), the maximum of random access guiding rise number (PreambleRetransMax) etc..User equipment sends random access guiding, the initial transmissions work(with Initial Trans Rate is directly proportional to the initial power constant；If Initial Trans fail to be detected by the network equipment, illustrate leading transmission Failure, the network equipment will not be sent to user equipment confirms instruction, and user equipment needs to start the corresponding leading climbing circulating cycle Phase, power is increased to certain power ramp step-length, through sending again after a period of time, until power is more than or equal to base station Value that equipment can detect simultaneously is confirmed, leading to send successfully.If user equipment, which retransmits leading number, exceedes the maximum Soaring number, base station equipment confirmation is not obtained yet, then sends failure.

Adjustment random access parameter described in the embodiment of the present invention refers to the value for adjusting random random access parameter, that is, is based on The initial value of random access parameter is adjusted, the random access parameter after being adjusted, the random access parameter it is initial Value can be pre-configured in base station equipment.

The embodiments of the invention provide a kind of method for adjusting random access parameter, referring to Fig. 2, this method includes：

101：Base station equipment receives the random access guiding that user equipment is sent according to random access parameter.

The user equipment can be the base station equipment cell in any one or any number of user equipmenies.

When user equipment needs to carry out transmitting uplink data, RACH (RACH, random can be passed through Access channel) send random access guiding.

Further, if RACH in cell both be present, there is also enhancing RACH (E-RACH, enhanced- Random access channel), user equipment can also use E-RACH to send random access guiding to base station.

102：After the base station equipment receives the random access guiding, confirmation message is sent to the user equipment, The confirmation message represents that the base station equipment is successfully received the random access guiding.

103：Base station equipment records the number of the confirmation message.

Base station equipment can record the number for the confirmation message for being sent to the user equipment, the number of the confirmation message The loading condition that can reflect on RACH, load too high, then it can cause the risk for channel congestion occur；If random access request is protected Hold and increase, congestion will occurs in RACH, influence the success rate of Stochastic accessing.

If user equipment sends random access guiding by E-RACH, the user equipment is properly termed as E-RACH user. The base station equipment can record the number of the confirmation message of the random access guiding for being sent on E-RACH.In channel congestion The transmission situation of the confirmation number of E-RACH random access guiding, the Stochastic accessing ginseng of optimization E-RACH user are considered in judgement Number can also effectively reduce E-RACH loads, lift the success rate of E-RACH user's Stochastic accessing.

Therefore, the channel congestion described in the embodiment of the present invention can include RACH congestion；Or E-RACH congestion；Or There is congestion in RACH and E-RACH.

The base station equipment can be recorded the number of the confirmation message issued in the cycle to user equipment by predetermined period, And record the number of the confirmation message in multiple predetermined periods.The base station equipment can also be to remembering in the multiple predetermined period The number of the confirmation message of record is filtered processing, and the number of the confirmation message after being handled, the confirmation after the processing disappears The number of breath can use as the number of the confirmation message.The filtering process refers to multiple confirmation messages of record Number filters out too high and too low number.It is to prevent actual time of the confirmation message in special time to be filtered processing Existing anomaly peak is counted, causes the adjustment flow for unnecessarily triggering random access parameter.The time span of the predetermined period It can be set according to system requirements and actual network operation situation, if for example, system can carry larger load, in advance If the time span that the cycle can be set can be more than the time span of the smaller load of system bearing；If real network is runed, net User in network is more, then the time span of predetermined period can set shorter, if the user in network is less, presets week The time span of phase can set longer.Or base station equipment can also carry out integrated condition and be configured the predetermined period Time span.For example, selection is 1 second, to ensure the precision of channel congestion judgement.In embodiments of the present invention, to default week The time span of phase does not limit.

The obtained number of confirmation message will be recorded to handle after filtering, it is ensured that subsequently according to after the processing really The number for recognizing message judges the accuracy of channel congestion state.By taking the base station equipment comprising base station and base station controller as an example, institute Two ways can be had by stating filtering process：

First way is that the number of the confirmation message is recorded by base station, and will record obtained confirmation message Number report base station controller, base station controller is filtered processing to the number of the confirmation message.Such as in WCDMA In system, the number of confirmation message described in Node B periodic reports, by RNC calculate that Node B report N number of (N ＞ 1, N is whole Number) confirmation message number average value.In order to reduce the influence to RNC chains of command, Node B can report week using longer Phase, such as 10s~30s.For example, report cycle is 10s, N 5, then Node B report 1 time and described record to RNC every 10s The number of the confirmation message arrived, RNC can record the number to 5 confirmation messages reported, then by this 5 confirmation messages Number of the average of number as the confirmation message after processing.

The second way is the record and filtering process for the number that confirmation message is completed by base station, after then handling really The number for recognizing message reports base station controller.Such as in WCDMA system, the confirmation is recorded in predetermined period by Node B The number of message, then the number of the confirmation message for recording to obtain in M predetermined period be average value processing, the M>1, M For integer.For example, the predetermined period is 10s, and M 5, the then 10s that Node B will recorded, 20s, 30s, 40s Average value processing is done with the number of 50s confirmation message, the number of the confirmation message after processing is reported into RNC.

Above two statistical is also applied for the 2G/3G communication systems such as GSM, CDMA.Only comprising base station LTE and subsequently Evolution system in, above-mentioned record and the processing confirmation message number can be completed by e-Node B.

104：Base station equipment makes comparisons the number of the confirmation message with the first thresholding, and first thresholding is used to indicate Channel congestion state.

Mapping relations be present with channel congestion state in first thresholding.The channel congestion state can pass through more seed ginsengs Count to represent, such as can be represented by congestion coefficient, it is assumed that the complete congestion of channel is that 100%, A is that (A's takes congestion coefficient It is worth between 0 to 1), then corresponding to A*100% congestion state, the first different thresholdings can be used to react.In order to embody to letter The prevention effect of road congestion, such as A could be arranged to reflect that channel congestion state is in the value of critical point, then corresponding first The ability that limit can handle random access request according to RACH or E-RACH determines, for A specific value in the present embodiment In can be not particularly limited.Therefore, different values can be taken corresponding to different channel congestion states, the first thresholding, for example, As shown in table 1, it is assumed that the number of confirmation message corresponding to the complete congestion of channel is 30 times per second.

First thresholding	Congestion coefficient	Congestion state
			15 times/per second	0.5	50%
9 times/per second	0.3	30%
			3 times/per second	0.1	10%

The thresholding of table 1 first and the mapping relations of channel congestion state are illustrated

It should be noted that the corresponding relation of the value of first thresholding and the congestion coefficient is only that one kind is shown Example, in actual applications, can set the mapping relations between the value of the first different thresholdings and different congestion coefficients, Mapping relations between the value of the first different thresholdings and the parameter of the expression channel congestion state, the present invention can be set Embodiment does not do any restriction herein.

Optionally, first thresholding can also reach cell according to same intra-cell users equipment random access request and expire Load determines that the cell represents the upper limit of base station equipment processing random access request at full capacity, can embody the channel Congestion state.The value of first thresholding is directly proportional to the ability of base station equipment processing random access request.Assuming that cell It is n times (N at full capacity>1, N is integer), then the first thresholding=N- △, △ can adjust according to method implementation effect dynamic.Example Such as, base station equipment is issued into 30 Stochastic accessing confirmation messages to user equipment in 1 second and be considered as cell at full capacity, then described first Thresholding can be by △ selection of 30-, such as can be 20 times to 25 times.First thresholding can be real according to network by base station equipment Border situation dynamic adjusts, and can also set with initial reference to empirical value, specifically be not construed as limiting in the present embodiment in advance.

When the number of the confirmation message is more than or equal to first thresholding, illustrate to need in current area it is to be processed with Machine access lead number is more, it is contemplated that the ability to bear of channel capacity, channel congestion risk be present.Can be random by reducing Access lead send frequency and quantity, alleviate channel pressure, avoid because there is channel congestion and caused by random access guiding send out Send failure.

If the number of the confirmation message is less than first thresholding, it is believed that the degree of current channel congestion also exists Within the tolerance range of the base station equipment, base station equipment can be successfully received random access guiding, not by channel congestion shadow Ring.

105：If the number of the confirmation message is more than or equal to first thresholding, the base station equipment adjustment connects at random Enter parameter, the random access parameter after being adjusted, and the random access parameter after the adjustment is sent to the user and set It is standby.

If the number of the confirmation message is more than or equal to first thresholding, illustrate the random access guiding of user equipment It is transmitted across more, it will the channel transmission quality of cell is adversely affected, can be by adjusting random access parameter, change connects Enter strategy, improve communication efficiency.

Optionally, if the number of the confirmation message is less than first thresholding, the base station equipment is without to random Access parameter is adjusted.

Optionally, the random access parameter that can be adjusted includes：It is the initial power constant of random access guiding, random Any two or three in the soaring number of power ramp step-length, the maximum of random access guiding of access lead.

Optionally, the adjustment mode of the random access parameter can be：Reduce the initial power constant and lift institute State power ramp step-length；Or reduce the initial power constant and increase the maximum soaring number；Or reduce the work( The soaring step-length of rate simultaneously increases the maximum soaring number；Or reduce the initial power constant, the lifting power ramp step Grow and increase the maximum soaring number.

Exemplified by reducing the initial power constant and lift the power ramp step-length, by reducing leading initial power Constant, the transmission power of first random access guiding in random access procedure can be reduced, ascending power is born so as to reduce The influence of load；By increasing the soaring step-length of pilot power, it is possible to reduce user equipment does the number of Stochastic accessing trial, and reduction connects Enter time delay, on the premise of the soaring number of maximum is constant, this time adjusts the emission maximum work(being likely to be breached to random access guiding Rate does not influence.

Above-mentioned random access parameter after adjustment is issued to user equipment in cell by base station equipment, and user equipment is afterwards In the random access request of initiation, the random access parameter after adjustment can be used to send random access guiding to base station equipment.

Optionally, base station equipment can be sent to user equipment in cell by way of Cell Broadcast CB.With WCDMA system Exemplified by, RNC can be by way of system message, for example, being believed by the system comprising cell public physic channel configuration parameter Block (SIB5) is ceased, the random access parameter after adjustment is issued to Node B, then the user is broadcast to by Node B and set It is standby.

Optionally, the initial value of random access parameter can be pre-set in base station equipment.The initial value is referred to Span as defined in agreement, it is configured by network practical operation situation.For example, according to initial power as defined in 3GPP agreements The optional scope of constant initial value is -35db~-10db, the optional scope of the power ramp step-length initial value for 1db~ 8db, the optional scope of the maximum soaring number initial value is 1 time~64 times.

Using method disclosed in the embodiment of the present invention, base station equipment according to record user equipment in cell is sent with The number of the confirmation message of machine access lead, to adjust random access parameter, what it is due to base station equipment record is confirmation message Number, then illustrate in current area, user equipment still can access network, and the channel condition of network does not deteriorate also, therefore According to the number of the confirmation message of the random access guiding, it can judge that user equipment is sent used in random access guiding in advance Channel whether there is congestion risk, if occurring the risk of channel congestion in current area, adjust random access parameter.Protect Before congestion occurs in RACH, user equipment can is sent and connect at random card using the random access parameter after optimization Enter leading, can prevent channel congestion occur, maintain Stochastic accessing success rate.

Optionally, the method described in the embodiment of the present invention is also applied for channel and congestion has occurred, before influenceing Stochastic accessing The situation of transmission is led, especially because random access guiding is transmitted across having aggravated channel congestion, is joined by adjusting Stochastic accessing more Number, pressure of the random access procedure to rach data capacity can be reduced, and then mitigate and even eliminate channel congestion.

In another embodiment, random access parameter after user equipment starts with adjustment is sent random After access lead, the random access channel congestion situation in cell can change therewith.Therefore, optionally, the present invention is real Apply in example, after step 105 has been carried out, step 106-1013 can also be included：

106：Base station equipment continues to the random access guiding that user equipment is sent in cell, the random access guiding Transmission process in used adjustment after random access parameter.

107：Base station equipment continues to send new confirmation message to the user equipment.

108：Base station equipment records the number of the new confirmation message, obtains the number of new confirmation message.

The obtained number one of confirmation message is recorded in the number and step 104 of the new confirmation message that the record obtains Sample, processing can also be filtered, using time of the new confirmation message obtained as record of the new confirmation message after processing herein Number, will not be repeated here.

109：The number of the new confirmation message is made comparisons with the first thresholding, if the number of the new confirmation message is still More than or equal to the first thresholding, step 1010 is transferred to；If the number of new confirmation message is less than the first thresholding, step 1011 is transferred to.

1010：Last adjustment result before issuing from this random access parameter adjustment flow to the user equipment or Person continues to adjust random access parameter.

If preceding once adjust in flow, through judgement, system is in channel congestion alert status, random access parameter is entered Adjustment is gone, then in this adjustment flow, can maintain to issue previous adjustment result to user equipment.It can continue to Random access parameter is adjusted, more effectively alleviates channel congestion state.

1011：The number of the new confirmation message is made comparisons with the second thresholding, second thresholding is less than described first Thresholding.Second thresholding is used to judge whether the random access guiding number that user equipment is sent is in normal scope.

Whether second thresholding can be used for weighing channel congestion state because random access guiding transmission subtracts Release less or base station is normal to random access request disposition, channel congestion do not occur, if the new confirmation message Number is less than second thresholding, illustrates before this judgement, and channel does not occur congestion or after user equipment is using adjustment Random access parameter send random access guiding, eliminated channel congestion.

If the number of the new confirmation message is less than or equal to second thresholding, step 1012 is transferred to；It is if described new true The number for recognizing message is more than the second thresholding, is transferred to step 1013.

1012：The base station equipment is recovered to issue the initial value of the random access parameter to user equipment.
