Description
Technical field
The present invention relates to the mobile communication technology field, relate to the jamming control method in the mobile communication system or rather.
Background technology
Congested control is the prerequisite function of mobile communication system.Mobile communication system is passed through the periodically load condition and the congestion condition of monitoring system Radio Resource, and appropriate, rational congested processing scheme is provided, thereby makes system can keep normal load condition.We can say that congested control is the important means that improves wireless resource utility efficiency, optimizes network quality, the quality of congested control and treatment will directly influence the performance of system.
At present, the processing after the small area jam mainly is to carry out at current link itself.Such as, during small area jam, forbid inserting new link, reduce the transmission rate of non-real-time service, when the voice user supports multi-rate modes, reduce voice user's speed, the user cut out link of congested sub-district, cut-out certain user or the like.For example, present gsm system takes place in the sub-district when congested, just may trigger the switching based on load, promptly initiatively the user is cut out congested sub-district.
Above-mentioned mentioned congested processing scheme is all very effective, because changing down, switching/release link will directly cause the release of power resource in the sub-district, code channel resource, thereby make cell load can recover normal soon.
But there is following shortcoming in these congested processing schemes:
1) present congested processing scheme is all just considered current link to congested influence, and does not consider the influence of latency to cell load, and this just makes the sub-district congested ping-pong may occur.
Such as, in the 3G system,, can the user in the sub-district be divided into two big classes according to user's state of living in: idle pulley and connection mode from the angle of radio network controller (RNC).Wherein connection mode can be divided into four classes again: can only monitoring seek channel (PCH, Paging Channel) paging information, receiving system information broadcast, and positional precision is the URA_PCH state of universal mobile telecommunications system (UTRAN) registration zone (URA, UTRAN Registration Area) level; Can only monitor PCH paging information, receiving system information broadcast, and positional precision is cell paging channel (CELL_PCH) state of sub-district (CELL) level; Positional precision is the CELL level, and the user can use common signal channel RACH to send the CELL_FACH state of upstream data, use forward access channel (FACH, Forward AccessChannel) receiving subscriber data; Positional precision is the CELL level, and transmits the CELL_DCH state of up-downgoing data by the dedicated channel (DCH, Dedicated Channel) that network side distributes.Wherein, the user who is in the CELL_DCH state has the greatest impact to cell load, though it is little to be in the customer impact of other states, quantity is a lot, and when especially being in congestion state in the sub-district, these users' influence also can not be ignored.Such as, the user who is in idle condition may upgrade or initiates professional and initiate Radio Resource control (RRC in this sub-district owing to the position, Radio ResourceControl) connection request, the user who is in URA_PCH/CELL_PCH state then may or have data to transmit because of position change to initiate cell update, and the user who is in the CELL_FACH state is then detecting always and using the common signal channel of this sub-district.That is to say that the user who is in these situations needs to use common signal channel, and the power of common signal channel is generally bigger, so these users may be bigger to the influence of time slot power under soft congested situation.
In view of the foregoing, if just take measures at current link, then may produce such problem: the sub-district is recovered normal and has been removed congested after congested processing, but ask to insert because of some new users, or because of user's request data transfer of non-CELL _ DCH state, and cause the very fast congestion state that enters in sub-district, also be that congested ping-pong appears in the sub-district.Obvious this situation is that operator and mobile subscriber are unwilling to see.
2) present congested treatment measures are bigger to the influence of user link, and have certain blindness.
It is congested why the sub-district occurs, and its reason is often a lot, such as, system hardware is limited in one's ability, the sub-district temporarily is in the heavy traffic phase or some abnormal conditions etc.Wherein preceding two kinds of situations be in the network planning, optimize be just should consider, also avoidable.Therefore, in general small area jam is small probability event.
In case but congested generation, consider from active user's angle, especially consider that from the user's that sets up link angle congested processing should be accomplished seamless harmless as far as possible, promptly do not allow the user discover the sub-district as far as possible and taken place congestedly, and will make the suffered influence of user drop to minimum.When congested generation, if user chain quality is normal, then should avoid processing to this user link as far as possible, more should avoid interrupting this user link as far as possible.And when switching by congested triggering, existing user's selection mode is ranked according to quality, pilot frequency intensity or the User Priority of current link often, therefrom select the certain user to switch then, obviously, this direct switching mode by network-triggered causes the user to go offline probably, especially the link user that is in normal condition goes offline, and this also is that operator and mobile subscriber do not wish to see.
Summary of the invention
In view of this, subject matter to be solved by this invention is to provide a kind of jamming control method, with when system congestion is controlled, can not impact existing user.
For addressing the above problem, the invention provides following technical scheme:

Embodiment
The present invention mainly is in that definite sub-district is current when being in congestion state, modification is in user's the handoff threshold of CELL_DCH state to improve user's handover trigger probability, make the user initiatively initiate handoff request and switch to other sub-districts, thereby reduce the number of users of this sub-district from this sub-district; Or revise cell selecting/reselecting parameters of the user who is in idle pulley and/or non-CELL _ DCH state, improve the threshold that these users select this sub-district, thereby reduce the probability that these users insert this sub-district.Wherein, non-CELL _ DCH state is meant other state except that the CELL_DCH state under the connection mode, comprises CELL_PCH state, CELL_FACH state and URA_PCH state.
At above-mentioned two kinds of processing schemes that provide, reach specific embodiment below more in conjunction with the accompanying drawings it is described in further detail.
At first, before congested control is carried out in the sub-district, need to determine whether the sub-district is current congested.Specifically can adopt existing soft congested determination methods to judge, promptly judge whether congested according to gross power or load value; Can also adopt existing hard congested determination methods to judge, promptly judge according to employed code channel in the sub-district.
With soft congested determination methods is example.At first the state of sub-district can be divided into two kinds of normal condition and congestion states, and the cell status before the definition load monitoring is Cell_Status_Old; Cell status after the load monitoring is Cell_Status_New, also needs to be provided with two load threshold value Threshold_1 and Threshold_2, and Threshold_1 is used to judge whether congested, and Threshold_2 is used to judge whether to transfer to normally.
Cell_Status_New is determined by two factors: current load value and Cell_Status_Old.Specifically, if current load value, is then thought small area jam greater than Threshold_1, promptly Cell_Status_New is a congestion state; Otherwise the sub-district is normal, and promptly Cell_Status_New is a normal condition.If current load value, thinks then that cell recovery is normal less than Threshold_2, promptly Cell_Status_New reverts to normal condition; Otherwise, small area jam, promptly Cell_Status_New is a congestion state.
The accuracy of judging for guaranteeing, definite sub-district is current be in congestion state after, a timer can also be set, and behind this timer expiry, judge the current congestion state that whether still is in sub-district, if, the current congestion state that is in definite sub-district then.Equally, after the current recovery normal condition in definite sub-district, a timer is set also, and at this timer expiry and the sub-district is current still be in normal condition after, determine the current normal condition of having recovered in sub-district.This is judged specifically as shown in Figure 1.
Definite sub-district is current be in congestion state after, can adopt two kinds of processing schemes of the present invention to carry out congested control.At first to first kind of processing scheme, the relevant treatment scheme of promptly revising the user's who is in the CELL_DCH state handoff threshold is described below.
Definite sub-district is current be in congestion state after, the user's who is in the CELL_DCH state handoff threshold can be revised by system, makes the user initiatively initiate handoff request.This situation is similar to cell breathing, and the switching band around the promptly congested sub-district moves to congested sub-district, but for the user, then the same with the switching of under normal circumstances being initiated.And owing to be that the user initiatively initiates handoff request, than the switching of initiatively being initiated by network, initiatively select at random to switch the user such as network, its outage probability is much lower.
Definite sub-district is current be in congestion state and revised the user's who is in the CELL_DCH state handoff threshold after, if the sub-district transfers normal condition to by congestion state, then can more original handoff threshold be returned in these users' handoff threshold adjustment.
Certainly, if the current congestion state that still is in sub-district, then can further adjust the user who is in idle pulley and/or non-CELL _ DCH state, specifically can be cell selecting/reselecting parameters of revising these users, and with amended parameter by broadcasting to the user.Such as, in system information block 3/4, IE " Cell Barred " value is revised as " Barred ", and IE " Intra-frequencycell re-selection indicator " value is set for " not allowed "; Perhaps revise the cell selecting/gravity treatment thresholding in the system information block 3/4, to reduce this selecteed probability in congested sub-district.
After having adjusted handoff threshold and having revised cell selecting/reselecting parameters,, then can more original value be returned in user's handoff threshold and cell selecting/reselecting parameters adjustment if the sub-district transfers normal condition to by congestion state.Specifically, can be at first original value to be returned in cell selecting/reselecting parameters adjustment, judge again afterwards whether the sub-district still is in normal condition, if still be in normal condition, then further user's handoff threshold is also adjusted back original value.Certainly, also can simultaneously handoff threshold and cell selecting/reselecting parameters all be adjusted back original value; Can also earlier original value be returned in the handoff threshold adjustment, after definite sub-district still is in normal condition, more original value be returned in cell selecting/reselecting parameters adjustment; Can also only adjust in handoff threshold and the cell selecting/reselecting parameters.Wherein, system is being returned handoff threshold and cell selecting/reselecting parameters adjustment after in original value one adjusts, and before another is adjusted, timer can also be set earlier, at timer expiry and the sub-district is current when still being in normal condition, adjust accordingly again.
In addition, after having adjusted handoff threshold and having revised cell selecting/reselecting parameters, if the current congestion state that still is in sub-district, the then all right private resource that further discharges the user is further to alleviate the load of sub-district.
When discharging user's private resource, the selection of user link can be carried out according to Different Strategies such as customer service priority or link-qualities.With the TD-SCDMA system is example, and the private resource quantity that needs to discharge can be weighed with basic resource unit (RU, the Resource Unit) number that is discharged, and wherein, RU is a radio resource units, corresponding to the code channel of a SF16.Such as, can be set to discharge the 6BRU/ sub-district.The parameter value of required release specifically can be by the Operation and Maintenance setting.
In addition, the release here refers to the release private resource.After discharging private resource, the release that the user of real time business may simultaneous RRC connects, this moment, the user entered idle pulley; And for the user of non-real-time service, RRC connects and then still can keep, this moment, the user did not enter idle pulley, but enter CELL_FACH, URA_PCH or CELL_PCH state, under these states, if network recovery is normal, the user link that discharges before can also recovering again, the link that therefore discharges the non-real-time service user is more much smaller than the real time business to the influence of customer service.In addition, in 3-G (Generation Three mobile communication system), non-real-time service is professional important component part, therefore when selecting to discharge user's private resource, under the identical situation of customer service priority, should preferentially discharge the user link of non-real-time service.
After the private resource that has discharged the user, if cell recovery normal condition, then cell selecting/reselecting parameters and handoff threshold adjustment can be returned original value equally.The concrete processing as hereinbefore do not repeat them here.
The basic handling flow process of above-mentioned first kind of scheme as shown in Figure 2.
Fig. 3 then is the detailed process flow process of this scheme.Corresponding with Fig. 3, at first to revise the user's be in the CELL_DCH state handoff threshold be step 1 to hypothesis, cell selecting/reselecting parameters of revising in the system information is a step 2, and the private resource that discharges the user is a step 3, and the corresponding sign Step_Flag of each step.If the step executed then identifies Step_Flag accordingly for true, otherwise is false.Under the situation that cell selecting/reselecting parameters was revised, adjusting back this parameter is step 1 ', under the situation that the sub-district handoff threshold was revised, the readjustment handoff threshold is a step 2 '.In addition, also be provided with timer T1 and T2, wherein T1 is after the small area jam, the minimum interval between adjacent two steps, T2 be cell recovery normal after, the minimum interval between the adjacent step.The concrete value of timer can be by the Operation and Maintenance setting.After having done above-mentioned setting, can realize the entire process of congested control by flow process shown in Figure 3.
Above-mentioned the scheme of at first carrying out the handoff threshold adjustment at the user who is in the CELL_DCH state is described, below again to second kind of processing, promptly at first carry out the scheme that cell selecting/reselecting parameters revises and describe at the user who is in idle pulley and/or non-CELL _ DCH state.
Definite sub-district is current be in congestion state after, cell selecting/reselecting parameters can be revised by system, to reduce the probability that user that this sub-district is in idle pulley and/or non-CELL _ DCH state selects.Such as, in system information block 3/4, IE " Cell Barred " value is revised as " Barred ", and IE " Intra-frequency cellre-selection indicator " value is set for " not allowed "; Perhaps revise the cell selecting/gravity treatment thresholding in the system information block 3/4.
Definite sub-district is current be in congestion state and revised cell selecting/reselecting parameters after, if the sub-district transfers normal condition to by congestion state, then can again cell selecting/reselecting parameters be adjusted into original value.
Certainly, if the current congestion state that still is in sub-district then can further be adjusted the user who is in the CELL_DCH state, such as, revise this class user's handoff threshold, switch to other sub-districts, thereby reduce the customer volume of this sub-district so that this class user is easier.
After having adjusted cell selecting/reselecting parameters and handoff threshold,, then can more original value be returned in user's cell selecting/reselecting parameters and handoff threshold adjustment if the sub-district transfers normal condition to by congestion state.Specifically, can be at first original value to be returned in user's handoff threshold adjustment, judge again afterwards whether the sub-district still is in normal condition, if then further original value is returned in cell selecting/reselecting parameters adjustment.Certainly, also can simultaneously handoff threshold and cell selecting/reselecting parameters all be adjusted back original value; Can also earlier original value be returned in cell selecting/reselecting parameters adjustment, after definite sub-district still is in normal condition, more original value be returned in the handoff threshold adjustment; Can also only adjust in handoff threshold and the cell selecting/reselecting parameters.Wherein, system is being returned handoff threshold and cell selecting/reselecting parameters adjustment after in original value one adjusts, and before another is adjusted, timer can also be set earlier, at timer expiry and the sub-district is current when still being in normal condition, adjust accordingly again.
In addition, after having adjusted handoff threshold and having revised cell selecting/reselecting parameters, if the current congestion state that still is in sub-district, the then all right private resource that further discharges the user is further to alleviate the load of sub-district.Here, identical to the release of user's private resource with the processing in first kind of scheme, therefore repeat no more.
Certainly, after the private resource that has discharged the user, if cell recovery normal condition, then cell selecting/reselecting parameters and handoff threshold adjustment can be returned original value equally.The concrete processing as hereinbefore do not repeat them here.
The complete process flow of above-mentioned second kind of scheme as shown in Figure 4.
The above only is the present invention program's preferred embodiment, not in order to limit protection scope of the present invention.
