Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the drawings and specific embodiments.
Referring to Fig. 2, the system construction drawing that Fig. 2 provides for the embodiment of the invention.As shown in Figure 2, this system can comprise: Operation and Maintenance entity (OM), ES management entity and an above radio access node.
In the said system structure, according to the present embodiment applied scene, its concrete structure is also different when specific implementation for the wireless access entity.Such as, if application scenarios is LTE, then the wireless access entity is Radio Access Network (RAN) node, if application scenarios is LTE-A, then this wireless access entity is eNB, if application scenarios is UTRAN, then this wireless access entity is RNC, if application scenarios is GERAN, then this wireless access entity is BSC.
In the said system structure, the ES management entity is a logic entity, can be independent of the OM and the wireless access entity of described system, also can be arranged in described OM or one of them the wireless access entity, and the embodiment of the invention does not specifically limit.It is mainly used in sets the ES attribute of each sub-district in the network.
Here, the ES attribute of sub-district mainly comprises at least one in " not allowing ES " attribute, " ES state " attribute and " covering the adjustment state " attribute.Comprise that with the ES attribute " not allowing ES " attribute, " ES state " attribute and " covering the adjustment state " attribute three are example below, respectively it is described one by one.
Wherein, " not allowing ES " attribute of sub-district is meant whether allow this sub-district to enter the ES state, as not allowing this sub-district to enter the ES state, then can not turn-off the radio frequency of this sub-district, as allow this sub-district to enter the ES state, then can turn-off the radio frequency of this sub-district, here, for ease of describing, first sign can be set represent not allow this sub-district to enter the ES state such as Y, second sign is set represents to allow this sub-district to enter the ES state such as N.Need to prove attribute just represents whether allow the sub-district to enter the ES state " not allow ES " here, and does not mean that this sub-district necessarily enters the ES state or enters the ES state scarcely.
" ES state " attribute of sub-district is meant the current ES state that whether enters in this sub-district.Usually, just meaningful effective " not allowing ES " attribute being provided with of being that second when sign should " ES state " attribute.Here,, the 3rd this sub-district of sign expression is set enters the ES state, promptly need to turn-off the radio frequency of this sub-district for ease of describing; The 4th this sub-district of sign expression is set does not enter the ES state, the promptly current radio frequency that does not need to turn-off this sub-district.Need to prove that above-mentioned the 3rd sign can equate that the 4th sign and remaining another identity equality specifically do not limit here with above-mentioned first sign and second one of them that identifies.
Whether " covering the adjustment state " attribute of sub-district is meant by the end of the covering of this sub-district being adjusted at present.Usually, after the sub-district entered the ES state, the RF of himself was closed, and had not also had the network coverage with regard to corresponding, and so, " covering the adjustment state " attribute of this sub-district is also just nonsensical.That is to say that " covering the adjustment state " attribute of sub-district is only just meaningful effective when " not allowing ES " attribute is first sign.Here, for ease of describing, the 5th sign expression is set the covering of this sub-district is adjusted, the 6th sign expression is not adjusted the covering of this sub-district.Need to prove that above-mentioned the 5th sign can equate that the 6th sign and remaining another identity equality specifically do not limit here with above-mentioned first sign and second one of them that identifies.
Consider that to make the present techniques scheme clearer, carry out visualization with the attribute of following table 1 pair sub-district and describe.Table 1
| Sub-district ID | Do not allow the ES attribute | The ES status attribute | Cover and adjust status attribute | Explain |
| Sub-district 1 | Second sign | Effectively, can be the 3rd sign or the 4th sign | NA (invalid) | If the ES status attribute is the 3rd sign, then turn-off the RF of sub-district 1, if be the 4th sign, then do not turn-off the RF of sub-district 1. |
| Sub-district 2 | First sign | NA (invalid) | Effectively, can be the 5th sign or the 6th sign | Not closing the RF of sub-district 2, is the 5th sign if cover the adjustment status attribute, has then adjusted covering of sub-district 2 |
| Lid if be the 6th sign, is not then adjusted the covering of sub-district 2 |
So far, finished description to the attribute of the sub-district that the present invention relates to.
Need to prove, above-mentioned ES management entity is carried out by dynamic coordinate between this ES management entity, OM and the radio access node three the setting operation of each sub-district ES attribute, this operation can tentatively be built up the back at network (being designated as situation 1) taken place, also can be when this ES management entity receive the ES open command that OM issues, (being designated as situation 2) takes place behind the current ES attribute that does not have above-mentioned each sub-district that configures.Below how the ES management entity being carried out setting operation is described.
Referring to Fig. 3, the flow chart that Fig. 3 provides for the embodiment of the invention.This flow process is applied to system architecture shown in Figure 2.In this flow process, if be example with situation 1, then when first establishing network, OM closes the ES management entity, and " not allowing ES " attribute that disposes all sub-districts in the network of this construction is first sign.Afterwards, after network tentatively builds up, carry out flow process as shown in Figure 3 according to actual needs.If with situation 2 is example, promptly send the ES open command to the ES management entity at OM, when the ES management entity is judged the current cell RF configuration parameter set (being designated as the second following cell RF configuration parameter set) that does not have described ES open command needs that dynamically obtained by self, execution flow process as shown in Figure 3.Here, the set of RF configuration parameter mainly comprises the ES attribute of sub-district and the RF configuration parameter of sub-district correspondence.
Based on top description, as shown in Figure 3, this flow process can may further comprise the steps:
Here, the RF configuration parameter of sub-district is the transmitting power of sub-district, the inclination angle etc. of bursting at the seams.
Here, can carry out by operation shown in Figure 4 during the definite specific implementation of step 303.Referring to Fig. 4, the flow chart of step 303 correspondence that Fig. 4 provides for the embodiment of the invention.As shown in Figure 4, this flow process can may further comprise the steps:
The described ES that step 401, ES management entity send according to WAP (wireless access point) in the time period traffic volume measurement of each sub-district obtain each sub-district at the average traffic T of this ES in the time period.
Here, if the number of the sub-district of average traffic maximum greater than 1, is then chosen one wantonly from the sub-district of this average traffic maximum, perhaps select one of them according to actual conditions, present embodiment does not limit.
Whether step 405 is gone back existence and is the sub-district of set condition not in each adjacent adjacent cells of cells in the determining step 404, if, current candidate cell set is formed in the sub-district of this existence, return execution in step 403, if not, then execution in step 406.
Here, if the sub-district of selecting in the step 403 is the sub-district A shown in Fig. 5 a, all adjacent sub-districts of the sub-district A that then mentions in step 404 are that sub-district F is to sub-district K.So, when carrying out this step 405, each adjacent adjacent cells of cells is the adjacent sub-district of sub-district F to sub-district K in the mentioned step 404 of this step 405.
So far, by flow process shown in Figure 4, can determine that non-conterminous sub-district in the candidate cell set is first sign such as " not allowing ES " attribute of the sub-district A to E shown in Fig. 5 a, be that sub-district A to E does not enter the ES state, and " not allowing ES " attribute of other sub-districts be second the sign promptly enter the ES state, promptly other sub-districts are the sub-district that enters the ES state.
In this step 304, make this sub-district enter the ES state is just closed this sub-district by radio access node RF.
So far, can realize making the RF of part sub-district in the network to close, reach the purpose of saving resource by above-mentioned steps.
One skilled in the art will appreciate that if the sub-district enters the ES state in the network, promptly close the RF of sub-district, then may cause in the network some sub-district to exist and not cover a little, promptly occur covering leak, this covering leak can cause unstable networks.For avoiding this covering leak, then need to carry out following step 305.
Here, the detection in the step 305 can be regular execution, also can be executed in real time, and the embodiment of the invention does not specifically limit.How to detect whether there is the covering leak in the network as for WAP (wireless access point), it can adopt existing testing mechanism to detect fully, no longer describes in detail here.
If the sub-district A to E shown in Fig. 5 a does not enter the ES state, and other sub-districts enter the ES state, when then entering the ES state in other sub-districts, coverage in the network is shown in Fig. 5 b, and in Fig. 5 b, the coverage of sub-district A to E is respectively each circle shown in Fig. 5 b, so, as can be seen, the zone that belongs to sub-district F of Fig. 5 b arrow indication is the zone that the covering of sub-district A to E does not relate to, and has promptly occurred not covering a little among the F of sub-district.
Here, covering leak is to judge by detecting the covering that does not enter the sub-district of ES state in the network, that is to say that the sub-district that detects this covering leak in the step 306 is specially detected sub-district when judging this covering leak, the current ES state that is not in this sub-district.Shown in Fig. 5 b, sub-district F is in the ES state, and sub-district A is not in the ES state, if radio access node finds that by the covering of detected cells A sub-district F causes this sub-district F the covering leak to occur owing to being in the ES state in step 305.So, when carrying out this step 306, whether the RF configuration parameter that the ES management entity just needs to judge the sub-district A that is not in the ES state is adjusted to maximum.
Be example still with Fig. 5 b, if the zone of arrow points is when the RF of sub-district A configuration parameter is adjusted to maximum, still detect this zone for covering leak in step 305, so, when carrying out this step 307, the sub-district that the covering leak appears in artificial unlatching is the sub-district F shown in Fig. 5 b, here, opens the sub-district F that the covering leak occurs and is specially: make sub-district F no longer be in the ES state.
Step 308 makes radio access node increase the RF configuration parameter of this sub-district, and " the cover adjustment state " attribute that disposes this sub-district is the 5th sign.Cover leaks all after the judgement in the completing steps 306 at all, execution in step 305.
Here, step 308 further comprises: radio access node reports the controlled result of RF configuration parameter of sub-district to OM, so that OM upgrades the RF configuration parameter of this sub-district.
Need to prove that as a kind of expansion of the embodiment of the invention, step 308 specifically can comprise:
Step 3081 judges whether the RF configuration parameter that detects the sub-district that covers leak is adjusted, if then execution in step 3082; Otherwise, execution in step 3083.
Step 3082 makes radio access node open the sub-district that leak occurs covering.
Here, step 3082 is specially: making radio access node is described the 4th sign with " ES state " attribute modification of this sub-district, so that this sub-district no longer enters the ES state.
Need to prove that step 3082 further comprises: the result that reporting cell is opened is to OM, so that OM upgrades the ES state of sub-district.
Step 3083, determine to increase the RF configuration parameter that this detects the sub-district that covers leak, and be notified to radio access node, increase the RF configuration parameter of this sub-district by this radio access node, and five sign of " covering the adjustment state " attribute for the covering of this sub-district is adjusted that disposes this sub-district.
Here, step 3083 further comprises: the result that the RF configuration parameter of reporting cell is increased is to OM, so that OM upgrades the RF configuration parameter of sub-district.
Step 309 makes the current ES attribute in each sub-district in the ES management entity record network, and corresponding RF configuration parameter, forms second cell RF configuration parameter set.
That is to say, when carrying out this step 309, based on the purpose of saving resource, finished setting to the ES attribute and the corresponding RF configuration parameter of each sub-district in the network, this setting is that the dynamic coordinate between OM, radio access node and the ES management entity is finished fully.
If with situation 1 is example, then in the subsequent network running, it can followingly be operated: OM sends a command to the ES management entity according to current actual conditions, if this orders the open command into ES, then the ES management entity is configured each sub-district in the network according to second cell RF configuration parameter set, if order then is configured each sub-district in the network according to first cell RF configuration parameter set for the ES shutdown command.
If with situation 2 is example, then after executing above-mentioned steps 309, the ES management entity is configured each sub-district in the network according to second cell RF configuration parameter set.Certainly, if in the subsequent network running, receive the ES shutdown command, then each sub-district in the network is configured according to first cell RF configuration parameter set.
So far, by top description, realized the flow process of the method that the embodiment of the invention provides.
Need to prove that corresponding to method shown in Figure 3, in the system shown in Figure 2, described OM is used for sending the ES open command to described ES management entity; Described ES management entity is used to judge the current cell RF configuration parameter set (being designated as second cell RF configuration parameter set) that whether has the described ES open command needs that dynamically obtained by self, if not, dynamically obtain cell RF configuration parameter set, and according to the RF configuration parameter set configuration respective cell of obtaining, if, according to described RF configuration parameter set configuration respective cell.
