Description
Technical field
The present invention relates to the communications field, relate in particular to lower electric control method, equipment and the system of a kind of BBU.
Background technology
Along with the increase gradually of mobile subscriber's quantity and the development of hardware technology, base station adopts distributed structure/architecture more, by RRU (Radio Remote Unit, radio frequency remoto module) and BBU (Base Band Unite, baseband processing unit) carry out the transmitting-receiving of signal, and the number of carriers of the upper carrying of each BBU is more and more.How effectively to manage the carrier resource on BBU, to reach the object of energy-saving and emission-reduction, become a concerned problem.
In prior art, generally realized carrier tank function on BBU, namely carrier resource does not belong to certain community, but is stored in carrier tank, distributes unitedly.So-called " pond " is a kind of mode that improves equipment operating efficiency, because when user uses carrier wave, therefore cause the existence of idle carrier wave, this idle carrier wave is put into carrier tank by BBU, and use this idle carrier wave that service is provided, and improves the service efficiency of carrier wave.For example, RNC (Radio Network Controller, radio network controller) by NBAP (Node-B Application Protocol, base station applies agreement) signaling is while setting up community, portion of carriers is distributed from carrier tank temporarily, when RNC is in the time deleting community by NBAP signaling, these interim carrier waves that distribute in the time setting up community reintegrate the unified management of carrier tank.
Meanwhile, base station is used carrier tank can realize the dynamic adjustment of cell carrier resource, as shown in Figure 1,
1, RNC detects that the number of users in community reduces;
2, RNC closes carrier wave unnecessary in this community by NBAP signaling base station;
In the time that number of users in community reduces, no longer need the carrier wave of original quantity, the number of users on the carrier wave having is 0, now, turn-offs this user and be 0 carrier wave, to economize on resources;
3, the carrier wave that whether has activation in BBU is detected in base station; If the testing result of base station is nothing, this BBU of electricity under base station;
4, RNC detects that the number of users in community increases;
5, RNC is opened or is increased the carrier wave in this community by NBAP signaling base station;
6, base station detects in BBU and has the carrier wave activating, for this BBU powers on.
In said process, RNC controls the distribution of BBU intercarrier flexibly by NBAP signaling, thisly can in the situation that not affecting the call of former community user, carry out the adjustment of BBU intercarrier, carrier wave be shifted, to reach the object of saving base-band resource from telephone traffic little community to telephone traffic great community.
In prior art, base station for the supply power mode of BBU is: no matter have how many carrier waves on this BBU, as long as have the carrier wave in state of activation on this BBU, base station is this BBU power supply.
The process that uses carrier tank dynamic community adjusting carrier resource according to above-mentioned base station, when base station detects the carrier wave not activating on BBU, base station stops powering to BBU.But base station generally includes multiple BBU, on each BBU, there are multiple carrier waves, and number of users on each carrier wave to be conventionally difficult to be 0 simultaneously, so just cause base station to detect not activating on BBU the situation probability of carrier wave very low; But the situation of scattered carrier wave probably appears in the carrier wave on BBU, the upper carrier number activating of BBU only has one to two, but now, base station still needs this BBU power supply.
Based on above-mentioned analysis, inventor thinks and has following shortcoming in prior art:

Concrete, the idle carrier wave Free_Frq of residue on described BBU BBU carrier number threshold value Min-N and other BBU of base station that above existing carrier number N, triggering carrier cycle are adjusted is set on described BBU;
Described regularization condition is specially:
N < Min-N, and Free_Freq>=Min-N.
Described base station also comprises after judging whether the upper carrier wave activating of described BBU meets regularization condition:
If the upper carrier wave activating of described BBU does not meet described regularization condition, described base station is continuously described BBU power supply.
Described base station sends request to described RNC, and to ask described RNC be zero by the adjustment of load of the upper described BBU carrier wave activating and turn-off the upper carrier wave activating of described BBU and be specially:
Described base station sends resource adjustment request to described RNC, asks described RNC to adjust the number of users of the upper carrier wave activating of described BBU;
Described base station structure resource status indication signaling, and send described resource status indication signaling to described RNC, indicates described RNC to turn-off the carrier wave that number of users is 0 after described adjustment.
Described base station, after described RNC sends request, also comprises:
Described RNC receives the resource adjustment request that described base station sends, and adjusts the number of users of described carrier wave according to described resource adjustment request, comprises the number of users of described carrier wave is adjusted into 0;
Described RNC receives the resource status indication signaling that described base station sends, and turn-offs according to described resource status indication signaling the carrier wave that number of users is 0.
By the method that adopts embodiments of the invention to provide, in the time that base station detects that RNC turn-offs carrier wave, base station checks the carrier wave that whether has activation on BBU; If when the carrier wave that the upper existence of BBU activates meets regularization condition, the load of the carrier wave on BBU is adjusted in base station by RNC, and close and adjust the carrier wave that back loading is 0, thereby can there is scattered carrier wave on BBU time, turn-off scattered carrier wave by adjusting the load of this scattered carrier wave, and then lower electric BBU, improve resource utilization.
The lower electric control method of introducing the BBU that embodiments of the invention provide below in conjunction with concrete application scenarios, as shown in Figure 3, comprises the following steps:
Step s301, RNC detects that in community, number of users diminishes, and sends the carrier wave request of turn-offing to base station.
In RNC, store the corresponding relation of user ID and user place carrier wave in community, as shown in table 1:
Table 1
| User | Carrier wave |
| First | A |
| Second | B |
| Third | C |
| Fourth | D |
| Penta | E |
| Oneself | F |
RNC is responsible for distributing and safeguarding the corresponding relation of user's and user place carrier wave community in, for example user's first, the second, third in table 1, fourth, penta and ownly distinguish corresponding carrier wave A, B, C, D, E and F.In the time that the user in community changes, or the carrier wave at user place is while changing, and RNC is known this variation in real time, upgrades the user of storage and the corresponding relation of carrier wave.In the time that the number of users in community reduces, the carrier wave that was originally assigned user may current number of users be 0, i.e. the load of this carrier wave is 0, carrier wave A, B, C as shown in table 2.
Table 2
| User | Carrier wave |
| A | |
| B | |
| C | |
| Fourth | D |
| Penta | E |
| Oneself | F |
The corresponding relation of user and carrier wave, in table 1 for corresponding one by one.Due to user's mobility, for example go on business and know that other reasons, user leave the scope of this community, do not recycle corresponding carrier wave and communicate.Now, in table 1, the load of original corresponding with user carrier wave becomes 0.As shown in table 2, be original user first, user second and user the third, for a certain reason, the scope of leaving this community causes the load on carrier wave A, B, C to be 0.Now, in order to save Internet resources, RNC need to turn-off carrier wave A, B, C.Concrete, base station is as the medium of communicating by letter between RNC and user, and in the time that RNC determines to turn-off carrier wave A, B, C, RNC turn-offs order by carrier wave and sends to base station, and this carrier wave turn-offs the carrier identification information of carrying carrier wave A, B, C in order.
In this application scene, with carrier wave and user correspond to one by one example, certainly, same carrier wave also can corresponding multiple different users, as shown in table 3:
Table 3
On carrier wave A in table 3, be assigned user first, user second and user third, in the time that three does not all finish the load relationship of carrier wave A, for example be transferred to carrier wave A carrier wave in addition, the number of users of the upper load of carrier wave A is not 0, only have in the time that user first, user second and user third leave this community, load on carrier wave A is 0, and with respect to carrier wave D, E, F, the probability that carrier wave A load is 0 is much smaller.
While occurring that in RNC is known community load is 0 carrier wave, the identification information of the carrier wave that RNC is further 0 according to load, sends message to base station, and informing base station turn-offs this carrier wave.The form of this message can be selected as required flexibly, and for example RNC can send by the signaling of NBAP form the request of turn-offing carrier wave to base station.
Step s302, base station receives the shutoff carrier wave request that RNC sends, and sends and turn-offs carrier wave response, the carrier wave that switching off load is 0 to RNC.
Base station receives after the shutoff carrier request message of RNC transmission, finds the upper corresponding carrier wave of BBU, and turn-off this carrier wave according to the identification information of the carrier wave in this message request, stops transmitting and receiving of this carrier wave.In conjunction with the carrier wave described in above-mentioned table 2 and user's corresponding relation, because the load of carrier wave A, B, C all becomes 0, carrier wave A, B, C are turn-offed in base station.
Step s303, base station checks the carrier wave that whether has activation on BBU.
If the result checking is: turn-off after carrier wave when base station, still there is the carrier wave of activation on BBU, execution step s304; When turn-off after carrier wave base station, the carrier wave not activating on BBU, execution step s309.
This step is the result that step s302 triggers, and only has base station to carry out after the operation of turn-offing carrier wave, and base station need to check the carrier wave that whether has activation on BBU.
Concrete, base station comprises multiple BBU, conventionally has the carrier wave of multiple activation on each BBU, the corresponding relation between base station stored BBU and carrier wave is as shown in table 4.
Table 4
In table 4, the corresponding carrier wave A of BBU1, B, C, D, the corresponding carrier wave E of BBU2, F, G, H.
When base station receives the shutoff carrier wave request that RNC sends, and turn-off after the one or more carrier waves on one of them BBU, upper scattered carrier wave or the upper carrier free situation of this BBU of just may occurring of this BBU, now, base station need to check the carrier case on BBU, checks on this BBU, whether also there are other carrier waves in state of activation.
In conjunction with the carrier wave described in above-mentioned table 2 and user's corresponding relation, and example in step s302, carrier wave A, B, C are turn-offed in base station, now only have the carrier wave D of an activation on BBU1, have carrier wave E, F, G, the H of activation, execution step s304 on BBU2.
If the carrier wave of the activation originally having on BBU1 is carrier wave A, B, C, now the upper carrier number activating of BBU1 is 0, execution step s309.
Step s304, base station checks whether the carrier wave on BBU meets regularization condition.
If base station detects the carrier wave on BBU and meets this regularization condition, performs step s305; Otherwise, if the carrier wave on BBU does not meet this regularization condition, perform step s310.
Base station sets in advance existing carrier number N on BBU on BBU, trigger the corresponding relation of the idle carrier wave Free_Frq of residue on BBU carrier number threshold value Min-N and other BBU of base station that carrier cycle adjusts;
The regularization condition of the upper carrier wave of BBU is specially:
In the time of N < Min-N, and
Free_Fre＞＝Min-N。
Concrete, in this application scene, in step s304, base station checks that whether the carrier wave on BBU meets the process of regularization condition, as shown in Figure 4, can comprise the following steps:
Step s3041, the regularization condition of the upper carrier wave of the default BBU in base station.
Concrete, the expression formula of the default regularization condition in base station is:
When N < Min-N, and Free_Freq>=Min-N;
Wherein, N is the upper current carrier number of BBU, and Min-N is the carrier number on the BBU that adjusts of the default triggering carrier cycle in base station, and Free_Freq is the idle carrier number of the residue on other BBU on base station.
In this application scene, N is introduced take 2 as example.
Step s3042, base station obtains the carrier number in current BBU, calculates and whether meets regularization condition.
Associative list 4, with the example that is described as to BBU in base station in step s303, base station obtains the carrier number in current BBU, learning on BBU1 only has 1 to activate carrier wave, on BBU2, there are 5 and activate carrier wave, and carrier wave G, the H of current BBU2, I are idle carrier wave, the implication of idle carrier wave is on this carrier wave, not have the number of users on user or this carrier wave not reach the maximum number of user that this carrier wave can carry.
Because activation carrier number 1 < of BBU1 triggers carrier number 2, and
Activation carrier number 3 > on BBU2 trigger carrier number 2,
So BBU1 meets regularization condition.
In this application scene, can be also other forms for the setting of regularization condition: for example regularization condition is set to:
N < Min-N; Wherein, N with the meaning of Min-N with identical described in step s3041.
In the time that carrier wave is turn-offed in base station, while checking the carrier wave on current BBU, know that carrier number on BBU1 is that 1 to be less than default Min-N be 2, base station judges that BBU1 meets regularization condition, and do not need to consider again Free_Freq on current BBU2 and the relation of Min-N, by RNC knowing that while there is idle carrier wave on BBU2, the user on upper BBU1 carrier wave is adjusted to the idle carrier wave on BBU2 by RNC informing base station.Concrete, the process that RNC informing base station carries out carrier wave adjustment by introducing in detail, does not repeat them here in following step s306.
Step s305, base station structure resource status indication signaling, and this signaling is sent to RNC, carrier resource adjustment need to be carried out in notice RNC base station.
In the resource status indication signaling that base station sends to RNC, carry solicited message, this solicited message is specially request RNC and meets other carrier wave of user assignment on the scattered carrier wave of BBU of regularization condition, and meets the carrier identification information of the scattered carrier wave on the BBU of regularization condition.
In this application scene, also carry the identification information of the target carrier of carrier resource adjustment in the resource status indication signaling that base station sends to RNC, this target carrier is the carrier wave on the BBU outside scattered carrier wave place BBU in base station.
Step s306, RNC receives after the resource status indication signaling of base station transmission, adjusts the relation of user and carrier wave according to this signaling.
Concrete, in RNC, store the corresponding relation between user and carrier wave.RNC receives after the resource status indication signaling of base station transmission, find corresponding carrier wave according to the identification information of scattered carrier wave in this signaling, and the user of carrying on this carrier wave, find target carrier according to the identification information of target carrier in signaling, and be this target carrier of above-mentioned user assignment.
Concrete, as shown in Figure 5, in this step, the process that RNC carries out signaling adjustment can comprise the following steps:
Step s3061, RNC receives the resource status indication signaling that base station sends, and searches the scattered carrier wave that need to carry out state adjustment.
In this application scene, RNC obtains the mode that scattered carrier wave carries out the target carrier of resource adjustment and can be:
The identification information that carries target carrier in the resource status indication signaling that A, base station send to RNC, RNC obtains target carrier according to the identification information of this target carrier;
The identification information that only carries scattered carrier wave in the resource status indication signaling that B, base station send to RNC, RNC obtains scattered carrier wave according to the identification information of scattered carrier wave, and then, RNC selects carrier wave as target carrier according to the load state of community intercarrier.
For example, in community, the load state of each carrier wave is as shown in table 5:
Table 5
In table 5, have carrier wave A, B on BBU1, wherein, carrier wave A provides service to user's first, and carrier wave B provides service to user's second, third; On BBU2, have carrier wave D, E, carrier wave D, E be respective user fourth, penta respectively; On BBU3, have carrier wave F, respective user is own.
RNC receives the Carrier State indication signaling that base station sends, and knows that according to the identification information of scattered carrier wave wherein this scattered carrier wave is carrier wave F, respective user oneself.Now, RNC is known the load state of carrier wave A～E, and the load of carrier wave A, D, E is all 1 user, and the load of carrier wave B is 2 users, and RNC can preferentially select suitable carrier wave as target carrier from carrier wave A, D, E; Certainly, in order to save carrier resource, RNC also can be preferably the allocation of carriers user that load is large, for example, be preferably carrier wave B distributing user, until the number of users of carrier wave B is while reaching maximum, then is other allocation of carriers user; Or RNC also can carry out user assignment according to BBU, be for example preferably the many BBU distributing user of carrier number in state of activation, certainly, this user is by the carriers carry on this BBU; In above-mentioned table 5, because the activation carrier number on BBU1 and BBU2 is all 2, therefore can not select BBU1 or BBU2 according to this kind of method, if carrier wave A, B, C are on BBU1 in table 5, RNC can be preferably the allocation of carriers user on BBU1, and then selects a carrier wave to carry user as target carrier in carrier wave A, B in BBU1, C.
Step s3062, RNC sends synchronization message by target carrier to user.
Step s3063, user sends response message to RNC, sets up the relation between target carrier.
Base station sends data by target carrier to user, and user receives the data that base station sends by target carrier, sends response to base station, sets up the corresponding relation between user and target carrier, and RNC completes the process that signaling is adjusted.
Step s307, RNC knows that the load of carrier wave F is zero, sends carrier wave turn-off request to base station, this carrier wave is turn-offed in request.
After the adjustment of load in previous step, the load vanishing of carrier wave F.After RNC detects that the load of carrier wave F is zero, judgement need to be turn-offed this carrier wave, to save Internet resources, sends carrier wave turn-off request to base station, carries the identification information of carrier wave F in this request.
Step s308, base station receives the carrier wave shutoff request that RNC sends, and turn-offs corresponding carrier wave.
Concrete, base station receives carrier wave and turn-offs after request, obtains the identification information of carrier wave F from this request, turn-offs carrier wave F, and as shown in table 5, the activation carrier number on BBU3 is 0.
Step s309, base station is checked through the carrier wave not activating on BBU, closes the power supply of BBU.
Turn-off after carrier wave base station, checks on BBU whether have the carrier wave of activation, if do not had, the power supply of this BBU is closed in base station.
Still be depicted as example with above-mentioned table 5, now BBU is checked through the carrier wave not activating on BBU3, and the power supply of BBU3 is closed in base station.
Step s310, base station is BBU continued power.
By the method that adopts embodiments of the invention to provide, in the time that base station detects that RNC turn-offs carrier wave, base station checks the carrier wave that whether has activation on BBU; If when the carrier wave that the upper existence of BBU activates meets regularization condition, the load of the carrier wave on BBU is adjusted in base station by RNC, and close and adjust the carrier wave that back loading is 0, thereby can there is scattered carrier wave on BBU time, turn-off scattered carrier wave by adjusting the load of this scattered carrier wave, and then lower electric BBU, improve resource utilization.
