Embodiment
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Under the framework of multi-operator share radio access network, according to the stock number that current terminal to be accessed need take, by the access control threshold value of overall access control threshold value and each operator, judge whether described terminal to be accessed can access Radio Access Network successively, to reach the optimal control of access; In addition, can also, according to the congestion control threshold value of global congestion control gate limit value and each operator, judge whether successively to occur congestion problems, and by the mode dynamic conditioning of releasing resource.Thus while the multiple operator of guarantee uses Radio Resource according to agreement, all right dynamically reasonable distribution wireless network resource, avoids the idle waste of wireless network resource, and prevents the overload of wireless network resource.
Below for LTE system, above-mentioned access control and congestion control procedure are described in detail, but the embodiment of the present invention is not limited to LTE system, is applicable to too in other wireless communication systems.
Describe the present invention below in conjunction with specific embodiment, but the present invention is not limited to following examples.
Embodiment one:
As shown in Figure 1, be connection control method flow chart in the embodiment of the present invention one, the method for the embodiment of the present invention one is applied in the system of multi-operator share radio access network, and connection control method mainly comprises the following steps:
Step 101: the stock number that terminal to be accessed need take, when receiving the access request of terminal to be accessed, is determined in base station.
In this step 101, the stock number that the business of terminal to be accessed request need take according to the traffic type information of carrying in access request, can be determined in base station.
The stock number that terminal to be accessed need take can characterize with the form of Resource Block (RB), also can characterize with other resource form, as with RRC linking number etc.The stock number that terminal to be accessed need take also can characterize with the form of the ratio (as 1%) of the stock number that need take and total resources.Stock number is characterized with RB in subsequent embodiment.
Step 102: base station judges whether the stock number that terminal to be accessed need take and the stock number sum that the current overall situation has taken are not more than overall access control threshold value, if so, then performs step 103; Otherwise, refusal terminal to be accessed access Radio Access Network.
Described overall access control threshold value is a default numerical value, for representing that the global resource total amount of Radio Access Network can occupied critical value, the stock number taken when the overall situation is greater than described overall access control threshold value, represents that Radio Access Network cannot access and holds the access of more terminal; Otherwise, represent that Radio Access Network can also hold the access of more multiple terminals.
The concrete manifestation form of described overall access control threshold value can be the numerical value (quantity as Resource Block) of stock number, also can be the ratio (as 95%) of stock number and the total resources taken in Radio Access Network.
Suppose: terminal to be accessed is the terminal a belonging to operator A, overall access control threshold value is 95%, and the stock number that the current overall situation has taken is 80%; If the stock number that terminal a need take is the stock number sum that 17%, the terminal a stock number that need take and the current overall situation have taken is 97%, be greater than overall access control threshold value 95%, then refusal terminal a in base station accesses Radio Access Network; If the stock number that the need of terminal a take is the stock number sum that 10%, the terminal a stock number that need take and the current overall situation have taken is 90%, be less than overall access control threshold value 95%, then the judgement performing step 103 can be continued in base station.
Step 103: base station judges the stock number that described terminal to be accessed need take and belongs to the current stock number sum taken of terminal of same operator with terminal to be accessed, whether be not more than the access control threshold value of terminal to be accessed operator, if so, terminal to be accessed is then allowed to access described Radio Access Network; Otherwise, perform step 104.
The access control threshold value of operator is a default numerical value, for representing that the Radio Resource distributing to operator can occupied critical value, the current stock number taken of terminal belonging to same operator is not more than the access control threshold value of this operator, represents that the terminal belonging to this operator can also access Radio Access Network; Otherwise, just need the judgement carrying out subsequent step, just can determine whether the terminal access Radio Access Network allowing to belong to this operator.
The concrete manifestation form of the access control threshold value of operator can be the numerical value (quantity as Resource Block) of stock number, also can be the ratio (as 40%) of the stock number that taken of the terminal belonging to this operator and total resources.
Suppose: terminal to be accessed is the terminal a belonging to operator A, the access control threshold value of operator A is 40%, and the current stock number taken of the terminal belonging to operator A accessed is 35%; If the stock number that terminal a need take is 10%, the stock number that terminal a need take is 45% with the current stock number sum taken of terminal belonging to operator A, be greater than the access control threshold value 40% of operator A, then the judgement operation of step 104 will be carried out in base station to terminal a; If the stock number that the need of terminal a take is 3%, the terminal a stock number that need take and the current stock number sum taken of terminal belonging to operator A is 38%, be less than the access control threshold value 40% of operator A, then base station allows terminal a access.
Step 104: base station is from the operator of share radio access network, judge in other operators, whether to there is the operator met the following conditions: the stock number that terminal to be accessed need take is not more than the access control threshold value of this operator with the current stock number sum taken of terminal belonging to this operator, if exist, terminal to be accessed is then allowed to access described Radio Access Network, if do not exist, then refuse terminal to be accessed and access described Radio Access Network.
Preferably, in order to ensure that the terminal belonging to the high operator of operator's priority can normally access, other operators that operator's priority is not more than operator's priority of terminal to be accessed operator can be selected in base station from the operator of share radio access network, and judge whether to exist the operator meeting described condition from other operators described in selecting.
Distinguishingly, if operator's priority of each operator is set to identical, then the terminal belonging to arbitrary operator all can rob the idling-resource with distributing to other operators, to make full use of Radio Resource.
Still to belong to the terminal a request access of operator A, in above-mentioned steps 103, although the stock number that terminal a need take and the current stock number sum taken of the terminal belonging to operator A accessed are greater than the access control threshold value of operator A, but the stock number sum that the stock number that need take due to terminal a and the current overall situation have taken is not more than overall access control threshold value, that is, also there is enough idling-resources and be supplied to terminal a in the overall situation, therefore, the access of terminal a directly need not be refused in base station, can from the operator of share radio access network, find out operator's priority other operators lower than operator A, suppose to find out operator B, base station can judge whether the stock number that terminal a need take and the current stock number sum taken of the terminal belonging to operator B accessed are not more than the access control threshold value of operator B further, if, then terminal a can take as the resource of operator B distribution is to access Radio Access Network, otherwise, refusal terminal a access.
In embodiments of the present invention, according to the stock number that current terminal to be accessed need take, by the access control threshold value of overall access control threshold value and each operator, judge whether described terminal to be accessed can access Radio Access Network successively, to reach the comparatively optimal control of access.Thus multiple operator uses Radio Resource according to agreement in guarantee, meanwhile, all right dynamically reasonable distribution wireless network resource, avoids the idle waste of wireless network resource.
The embodiment of the present invention two additionally provides a kind of jamming control method, it should be noted that, scheme involved by the present embodiment two is the control method implemented for produce congested of industry form of ownership, includes but not limited to access control mode in embodiment one and the congestion problems that produces.
Following congestion control can be triggered by event possible arbitrarily, and such as access-in resource is not enough, or cycle inspection etc.Embodiment two specifically describes the program below.
Embodiment two:
As shown in Figure 2, be jamming control method flow chart in the embodiment of the present invention two, mainly comprise the following steps:
Step 201: base station judges whether the stock number that the current overall situation has taken is not less than global congestion control gate limit value, if so, then performs step 202, otherwise, without the need to carrying out congestion control.
Described global congestion control gate limit value is a default numerical value, for representing that congested critical value appears in the whole wireless network resource of Radio Access Network, the stock number taken when the overall situation is not less than described global congestion control gate limit value, represents that Radio Access Network has occurred congested; Otherwise, represent that Radio Access Network does not occur congested.
The concrete manifestation form of described global congestion control gate limit value can be the numerical value (quantity as Resource Block) of stock number, also can be the ratio (as 90%) of maximum resource amount and the total resources that can take in Radio Access Network.
Suppose: in this step 201, because cycle inspection triggers congestion control, and global congestion control gate limit value is 90%.The stock number that the current overall situation has taken need be added up in base station, and compares with global congestion control gate limit value.If the stock number that the current overall situation has taken is 85%, be less than global congestion control gate limit value 90%, then without the need to carrying out congestion control; If the stock number that the current overall situation has taken is 97%, be greater than global congestion control gate limit value 90%, then base station needs to judge whether the resource occupation amount of each operator is greater than the congestion control threshold value of each operator further, resource occupation amount is greater than the release of the stock number shared by a terminal part for the congestion control threshold value of operator, to reduce the stock number that the overall situation has taken.
Step 202: determine to belong to same operator and the stock number taken is not less than the terminal of the congestion control threshold value of this operator.
The congestion control threshold value of operator is a default numerical value, for representing that congested critical value appears in the wireless network resource distributing to operator, the current stock number taken of terminal belonging to same operator is less than the congestion control threshold value of this operator, represents that the wireless network resource distributing to operator occurs congested; Otherwise, represent that the wireless network resource distributing to operator does not occur congested.
The concrete manifestation form of the congestion control threshold value of operator can be the numerical value (quantity as Resource Block) of stock number, also can be the ratio (as 40%) of the terminal belonging to this operator maximum resource amount that can take and total resources.
Suppose that the congestion control threshold value of operator A is 55%, the congestion control threshold value of operator B is 20%, and the congestion control threshold value of operator C is 8%; The stock number that all terminals that statistics obtains belonging to operator A have taken is 60%; The stock number that all terminals belonging to operator B have taken is 30%, and the stock number that all terminals belonging to operator C have taken is 5%.Can determine according to statistics, the stock number that the terminal belonging to operator A has taken is not less than the congestion control threshold value of operator A, represents that the wireless network resource distributing to operator A occurs congested; In like manner, the stock number that the terminal belonging to operator B has taken is not less than the congestion control threshold value of operator B, represents that the wireless network resource distributing to operator B occurs congested; And the stock number that the terminal belonging to operator C has taken is all less than the congestion control threshold value of operator C, represent that the wireless network resource distributing to operator C does not occur congested.Therefore, can determine to meet belong to same operator and the terminal that the stock number taken is not less than this condition of congestion control threshold value of this operator be: belong to the terminal of operator A and belong to the terminal of operator B.
Step 203: discharge the resource shared by described terminal determined, the stock number that the current overall situation has been taken is less than described global congestion control gate limit value.
Preferably, when the described terminal that step 202 is determined is the terminal belonging to different operators, in order to ensure that the terminal belonging to the high operator of operator's priority can maintain regular traffic, congestion control can be carried out in the following manner, specifically comprising:
According to operator's priority order from low to high of operator, the resource of release shared by terminal successively, when release belongs to the resource shared by the terminal of an operator at every turn, judge whether the stock number that the current overall situation has taken is not less than global congestion control gate limit value, if, then continue the resource shared by terminal that release belongs to the higher operator of operator's priority, otherwise, stop the resource of release shared by terminal.
Particularly, if the terminal determined in step 202. is belong to the terminal of operator A and belong to the terminal of operator B, and the priority of hypothesis operator A is higher than the priority of operator B, then in this step 203, first the resource shared by the terminal belonging to operator B can be discharged, if after release belongs to the resource shared by terminal of operator B, the stock number that the current overall situation has taken is less than global congestion control gate limit value, then no longer can discharge the resource shared by the terminal belonging to operator A, stop resource release operations; If after release belongs to the resource shared by terminal of operator B, the stock number that the current overall situation has taken is still not less than global congestion control gate limit value, then need to continue to discharge the resource shared by terminal belonging to operator A, until the stock number that the current overall situation has taken is less than described global congestion control gate limit value.
Preferably, discharge belong to same operator terminal shared by resource time, in order to ensure that the business that service priority is higher can be executed correctly, base station can according to service priority order releasing resource from low to high, particularly:
According to the service priority belonging to each terminal of same operator, reduce the service rate that service priority is less than the business of business-level threshold value, and whether the current shared stock number of the terminal judging to belong to this operator is not less than the congestion control threshold value of this operator;
If, then stop the business that service priority is less than business-level threshold value, and reduce the service rate that service priority is not less than the business of business-level threshold value, until the current shared stock number of the terminal belonging to this operator is less than the congestion control threshold value of this operator.
The terminal supposing to belong to operator B has these 5 terminals of terminal B1 to terminal B5, these 5 terminals have run 8 business (wherein the multiple business of some terminal operating) altogether, business-level threshold value is X, the service priority of 5 business is had to be less than X, the service priority of residue 3 business is not less than X, when release belongs to the resource of the terminal of operator B:
First reduce the service rate that service priority is less than 5 business of X, after then judging that the service rate of these 5 business reduces, whether the current shared stock number of terminal belonging to operator B is not less than the congestion control threshold value of operator B.
If not, then when the stock number that the current overall situation has taken is still not less than global congestion control gate limit value, continue the resource shared by terminal that release belongs to operator A, when the stock number that the current overall situation has taken is less than global congestion control gate limit value, stop the resource of release shared by terminal.
If, then stop 5 business that service priority is less than X, and reduce the service rate that service priority is not less than 3 business of X, until the current shared stock number of the terminal belonging to operator B is less than the congestion control threshold value of operator B, afterwards, continue to judge whether the stock number that the current overall situation has taken is still not less than global congestion control gate limit value, and continue to discharge the resource shared by the terminal belonging to operator A or the resource shared by stopping release terminal according to judged result.
In embodiments of the present invention, according to the congestion control threshold value of global congestion control gate limit value and each operator, judge whether successively to occur congestion problems, and pass through the mode dynamic conditioning of releasing resource, the stock number that the current overall situation has been taken is less than global congestion control gate limit value.Thus multiple operator uses Radio Resource according to agreement in guarantee, meanwhile, all right dynamically reasonable distribution wireless network resource, and prevent the overload of wireless network resource.
