Embodiment
Main thought of the present invention is: terminal inserts, and when the connecting terminal number is less than the maximum number of terminals of this sub-district in the sub-district that definite terminal inserted, according to for the relevant private resource situation of terminal distribution and this sub-district corresponding district state, determine whether terminal can insert described sub-district.Wherein, being provided with of cell status can be in the RNC side, also can be in Node B side.
Below, be described with reference to the accompanying drawings the realization of acceptance controlling method of the present invention and device by specific embodiment.
Acceptance controlling method provided by the present invention goes for shared channel, HSDPA, HSPA+ and 3GPP Long Term Evolution (LTE) system etc. of HSUPA system, R4.In following embodiment, be that example describes with low spreading rate (LCR) time division duplex (TDD) HSUPA system.
Acceptance controlling method schematic flow sheet when Fig. 1 is positioned at RNC for cell status setting of the present invention, as shown in Figure 1, this method comprises:
Step 101: when terminal inserted first or re-accesses, RNC judged the maximum number of terminals of the HSUPA the business whether number of terminals that connected in the sub-district that described terminal wishes to insert is supported less than this sub-district, if less than, then execution in step 102; Otherwise, execution in step 105.
The access procedure of being initiated when here, terminal inserts to the first access network of terminal first; Terminal re-access the access procedure of when a sub-district switches to another sub-district, being initiated for terminal.Wherein, how described maximum number of terminals is set specifically, and how carries out described judgement and belong to known technology, repeat no more here.
Step 102:RNC is the terminal distribution downlink dedicated channels, if downlink dedicated channels is allocated successfully, then execution in step 103; Otherwise, execution in step 105.
Wherein, RNC is that the resource of terminal distribution changes according to the applied system of acceptance controlling method of the present invention is different, for example, in HSDPA for user's distribution be the up-downgoing dedicated channel, in HSPA+, can not distribute private resource for the user.In the following description, above-mentioned situation is referred to as: RNC is the relevant private resource of terminal distribution.
Wherein, how RNC specifically distributes described relevant private resource to belong to known technology, repeats no more here.
Step 103:RNC differentiates cell status according to the cell status variable, if the cell status variable inserts for allowing, then execution in step 104, if the cell status variable inserts for refusal, then execution in step 105.
Wherein, RNC differentiates cell status and is specially: why the current concrete setting of cell status variable of differentiating corresponding expression cell status is worth, thereby obtains current cell status according to the current set point of cell status variable.The method to set up of described expression cell status variable can be used method as shown in Figure 3, will carry out the detailed description of cell status variable method to set up flow process in the explanation of Fig. 3, does not give unnecessary details here.
In addition, in the embodiment shown in fig. 1, the described differentiation cell status of the differentiation of cell status and cell status variable, and the method to set up of cell status also can be placed among the Node B and finishes, in the described embodiment of Fig. 2, will be elaborated, repeat no more here.
As shown in Figure 3, described cell status is divided into two kinds: allow to insert and the refusal access.
Step 104:RNC returns corresponding access success message to terminal, and current flow process finishes.
Step 105:RNC returns corresponding access failure message to terminal, and current flow process finishes.
Further, among the embodiment shown in Figure 1, step 102 can be put upside down with the order of step 103, and promptly step 102 and step 103 can respective change be:
Step 102 ': RNC differentiates cell status earlier, is example with the cell status method for expressing shown in Fig. 3, when cell status inserts for permission, execution in step 103 '; Otherwise, execution in step 105.
Step 103 ': RNC is the descending assigned with dedicated channel of HSUPA terminal, if downlink dedicated channels is allocated successfully, then execution in step 104; Otherwise, execution in step 105.
Acceptance controlling method schematic flow sheet when Fig. 2 is positioned at Node B for cell status setting of the present invention, as shown in Figure 2, this method comprises:
Step 201: when terminal inserted first or re-accesses, RNC judged that whether the HSUPA terminal that connected in certain sub-district support the maximum number of terminals of HSUPA business less than this sub-district, if less than, then execution in step 202; Otherwise, execution in step 210.
Wherein, how described maximum number of terminals is set specifically, and how carries out described judgement and belong to known technology, repeat no more here.
Step 202:RNC is this terminal distribution downlink dedicated channels, if downlink dedicated channels is allocated successfully, then execution in step 203; Otherwise, execution in step 210.
Wherein, how RNC specifically distributes described downlink dedicated channels to belong to known technology, repeats no more here.
Step 203:RNC sends Radio Link to Node B and sets up or reconfiguration request message, requires Node B to distribute resources such as control channel.
Wherein, for inserting first or re-accessing, RNC sets up or reconfiguration request message to the corresponding transmission Radio Link of Node B according to the terminal that inserts in the step 201.And, wish in the step 201 that the terminal insert need carry out shared channel when inserting, then Radio Link is set up and will be comprised shared channel in message or the reconfiguration request message and use indication information in this step.
Described shared channel uses indication information, is used to indicate whether that needs use shared channel, for example comprises information element (IE): strengthen dedicated channel information (E-DCH information) or high speed descending sharing channel (HS-DSCH) information etc.
Step 204:Node B receive that Radio Link that RNC sends is set up or reconfiguration request message after, Node B judges that whether containing described shared channel in the message uses indication information, as if containing this information, then execution in step 205; Otherwise execution in step 207.
Wherein, how Node B specifically carries out the judgement of described message can be used correlation technique of the prior art to finish, and repeats no more here.
Wherein, adding described shared channel described in the step 203 in the message uses the execution of indication information and step 204 to be to have considered that the terminal that is inserted in the practical application is not the situation of carrying out the shared channel access.
In method provided by the present invention, the described message that sends in the step 203 can not add described shared channel and use indication information, and step 204 can be omitted.At this moment, after Node B receives described message, direct execution in step 205.
Step 205:Node B differentiates cell status according to the cell status variable, if the cell status variable inserts for refusal, then execution in step 206; If the cell status variable inserts for allowing, then execution in step 207.
Identical with the operation in the step 103, difference is that this operation finished by Node B, but not finishing by RNC described in the step 103.
Step 206:Node B returns Radio Link to RNC and sets up or reconfiguration failure message, afterwards, and execution in step 208.
Wherein, set up message or reconfiguration request message for Radio Link, return Radio Link accordingly and set up failed message or reconfiguration failure message according to what Node B received.Specifically how to generate described failed message and return RNC and belong to known technology, repeat no more here.
Step 207: according to the message that receives, Node B disposes related resource, and returns Radio Link to RNC and set up or reshuffle success message.
Wherein, the resource information of required configuration is set up in message or the reconfiguration request message at the described Radio Link that receives and is carried, and specifically how to carry out resource distribution according to described message and belongs to known technology, repeats no more here.And, described in step 204, be not the situation of shared channel owing to comprise the channel that terminal asks to insert in the embodiment shown in Figure 2, therefore, the resource that Node B disposed may not be a shared resource also here.
Wherein, set up message or reconfiguration request message for Radio Link, return Radio Link accordingly and set up success message or reshuffle success message according to what Node B received.
Step 208:RNC receives the described message that Node B returns, and differentiates type of message, if Radio Link set up or reshuffle success message, execution in step 209, if Radio Link is set up or reconfiguration failure message, then execution in step 210.
Step 209: return the access success message to terminal, insert corresponding sub-district to admit terminal, current flow process finishes.
Step 210: return access failure message to terminal, insert corresponding sub-district with the refusal terminal, current flow process finishes.
Fig. 3 is the method to set up schematic flow sheet of cell status variable of the present invention.Before the detailed description of carrying out step shown in Figure 3, at first introduce to give a definition:
Dispatch request: with Transmission Time Interval (TTI, Transmission Time Interval) is sweep spacing, and the cache information of all terminals is scanned, in case find have data to exist in the buffer memory of certain terminal, promptly thinks and triggers a dispatch request;
Scheduling allows: with TTI is sweep spacing, and every the transmission to terminal of scheduler once dispatched permission information, is a scheduling and allows.Described scheduling allows message for distributing transfer of data such as code channel or receiving necessary information.
As shown in Figure 3, cell status variable method to set up of the present invention comprises:
Step 301: it is 0 that initialization dispatch request variable M and scheduling allow the initial value of variable N, and cell status variable Cell_Access_State is initialized as and allows to insert, and the acceptance judging factor is α.
Described dispatch request variable is used to write down the dispatch request quantity in the TTI who is added up; Described scheduling allows variable, is used to write down the quantity that the scheduling in the TTI who is added up allows; Described cell status variable Cell_Access_State comprises two kinds of situations, is respectively: allow to insert and the refusal access; Described acceptance judging factor-alpha is a preset value, can independently set as the case may be, and it can obtain by modes such as emulation, specifically how to obtain the described acceptance judging factor by emulation and belongs to known technology, repeats no more here.
Step 302: the quantity that the dispatch request in the statistic period T, scheduling allow, charge to dispatch request variable M respectively and allow among the variable N with scheduling.
Wherein, step 302 continues to carry out described statistics in whole implementation.
Step 303: judge whether measurement period arrives, if arrive, then execution in step 304, otherwise, continue to judge, after measurement period arrives, execution in step 304.
Step 304: allow variable N according to dispatch request variable M with scheduling, calculate outputting measurement value η Measure, smoothly be η with it i, execution in step 305; And, allow variable N to be reset to 0, execution in step 302 dispatch request variable M and scheduling.
Wherein, η MeasureComputing formula can for:
η measure = N + b M + a , 0≤b≤a, and a ≠ 0.
Wherein, 0＜η Measure≤ 1, and, at η MeasureComputing formula in add constant a and b reason be the situation that prevents that denominator equals 0, therefore, the value of a, b in general should be as far as possible little, for example, the value that can get a and b is all smaller or equal to 1; But when statistic period T is bigger, and then the statistical value of M and N is when big, and for example the value of M and N may be 100, even bigger, at this moment, and at η MeasureCalculate according to M and N, and do not influence η MeasureUnder the principle of computational accuracy, a, b also can get the value greater than 1, do not limit here.
Perhaps, when establishing period T and being n TTI, then also can try to achieve the ratio of the quantity of scheduling permission in each TTI and dispatch request earlier respectively, carry out the calculating of outputting measurement value again, formula is:
η measure = 1 n Σ j = 1 n N j + b M j + a , Wherein, 0≤b≤a, and a ≠ 0;
Wherein, j represents the sequence number of each TTI in the measurement period, N jJ the interior scheduling of TTI allows quantity, M in the expression measurement period jJ dispatch request quantity that TTI is interior in the expression measurement period.
Further, with above-mentioned first η MeasureIn the computing formula, identical for the principle of a, b value, the value of generally getting a and b is all smaller or equal to 1, and still, when M in a TTI and N value were big, the value of also not getting rid of a and b was greater than 1 situation.
In addition, state outputting measurement value in realization, the outputting measurement value η of counting statistics period T correspondence according to each TTI correspondence MeasureThe time, can use the method flow of step 301～step 307 equally, difference only is, in the step 302, preserves the scheduling permission of statistics in each TTI and the quantity N of dispatch request respectively jAnd M jAccordingly, in the step 304, when each statistic period T arrived, all N resetted jAnd M j
Certainly, in actual applications, also may exist other to realize this Calculation Method, for example: use the method flow of step 301～step 307 equally, and in step 302, the N of each the TTI correspondence that obtains according to statistics jAnd M j, directly calculate the outputting measurement value and the preservation of this TTI correspondence; Accordingly, in step 304,, try to achieve the mean value of above-mentioned outputting measurement value, be the pairing outputting measurement value η of this measurement period directly according to the outputting measurement value of each TTI correspondence in the statistic period T of preserving MeasureAt this moment, that need reset no longer is M and N, but preserves the variable of the corresponding outputting measurement value of each TTI.
With η MeasureLevel and smooth is η iComputing formula be: η i=f η I-1+ (1-f) η Measure, wherein, f is a smoothing factor, η 0=0, establishing current measurement period sequence number is i, then η iRepresent the outputting measurement value after the pairing smoothing processing of current measurement period; η I-1Represent the outputting measurement value after the pairing smoothing processing of previous measurement period of current measurement period, also i.e. outputting measurement value after i-1 pairing smoothing processing of measurement period.Because i represents the sequence number of measurement period, therefore, the value of i is to be not less than 1 integer.
Wherein, the outputting measurement value η that also can use initial calculation to go out MeasureAs the criterion in the step 305, that is: directly judge η in the step 305 MeasureWhether＞=α sets up.
Wherein, how to realize specifically that in actual applications described calculating belongs to known technology, repeats no more here.
Step 305: judge η iDoes＞=α set up? if set up, then execution in step 306; If be false, then execution in step 307.
Step 306: cell status variable Cell_Access_State is set to allow to insert, and current flow process finishes.
Wherein, setting specifically how to carry out described variable belongs to known technology, repeats no more here.
Step 307: cell status variable Cell_Access_State is set to refusal and inserts.
Wherein, in method to set up shown in Figure 3, though the cell status variable use to allow inserts and refusal inserts the expression cell status,, not limiting the concrete method for expressing of cell status here, in actual applications, can independently set.
Fig. 4 realizes admitting the apparatus structure schematic diagram of control for the present invention, this device can be used as RNC and is applied in the acceptance controlling method of the present invention, as shown in Figure 4, this device comprises: number of terminals judge module 410, access judge module 420, cell status are provided with module 430, message generating module 440 and data transmission blocks 450; Wherein,
Number of terminals judge module 410, when being used for the terminal request access, judge the maximum the number of terminals whether number of terminals that connects in self corresponding device corresponding district is supported less than this sub-district, if, then send and judge that signal is to inserting judge module 420, if not, then failed message is generated signal and send to message generating module 440.
Insert judge module 420, after being used to receive described judgement signal, be the relevant private resource of terminal distribution, and to cell status module 430 is set and searches cell status, when be correlated with for terminal distribution private resource success and cell status insert for permission, success message is generated signal send to message generating module 440, otherwise, failed message is generated signal send to message generating module 440.
