Below in conjunction with accompanying drawing, method provided by the invention and device and corresponding system are described in detail with specific embodiment.

Embodiment 1:

The flow chart of the Home eNodeB power-economizing method that Fig. 3 provides for the embodiment of the present invention 1, specifically comprises following treatment step:

Step 301, centralized node send load information request according to default RQ cycle to the Home eNodeB under this centralized node.

Wherein, this default RQ cycle can and need to arrange flexibly according to practical experience.

Step 302, receive after load information request when the Home eNodeB under this centralized node, self present load and maximum load are sent to this centralized node by Home eNodeB.

The present load of all Home eNodeB that step 303, this centralized node connect according to self and with the maximum load of all Home eNodeB and ratio, determine current network idling-resource.

In this step, this ratio and current network idling-resource negative correlation, this ratio is larger, and current network idling-resource is less.This centralized node can specifically be determined this current network extra spare resource according to following formula:

$\mathrm{free}=1-\frac{\underset{i=1}{\overset{N}{\mathrm{\Σ}}}\mathrm{cell}\left(i\right).\mathrm{load}}{\underset{i=1}{\overset{N}{\mathrm{\Σ}}}\mathrm{cell}\left(i\right).\mathrm{load}\_\max };$

Wherein, free is current network idling-resource, the current load value that cell (i) .load is i base station, the maximum load value that cell (i) .load_max is i base station, the i.e. bearing capacity of i base station, N is the number of all Home eNodeB under this centralized node.

Home eNodeB under step 304, this centralized node obtains the load information of this current network extra spare resource and adjacent Home eNodeB according to predetermined period.

In this step, this Home eNodeB can send idling-resource solicited message and send load information request to adjacent Home eNodeB to this centralized node according to predetermined period, when this centralized node receives after this idling-resource solicited message, current network idling-resource is sent to this Home eNodeB by this centralized node, and when adjacent Home eNodeB receives after this load information request, the ratio of the present load of self and maximum load is sent to this Home eNodeB by adjacent Home eNodeB.

Step 305, this Home eNodeB, according to the load information of adjacent Home eNodeB, current network idling-resource and self load information, are determined the current low load-threshold of this Home eNodeB.

In this step, the load information of this current low load-threshold and the adjacent Home eNodeB relation that is inversely proportional to, proportional with the maximum load of this current network extra spare resource, this Home eNodeB.This current low load-threshold specifically can calculate according to following formula:

Wherein, the maximum load value that max_load is this Home eNodeB, mean () represents to average, neighbour_load _jfor the present load of adjacent Home eNodeB j and the ratio of maximum load, free is current network idling-resource, and loadL_threshold is current low load-threshold.

Step 306, this Home eNodeB determine whether present load is not more than this current low load-threshold, if so, enters step 307, if not, enters step 321.

Step 307, in the time that this Home eNodeB determines that present load is not more than this current low load-threshold, this Home eNodeB sends sleep request to this centralized node.

In this step, the present load of Home eNodeB is not more than this current low load-threshold, and this Home eNodeB not dormancy be that load is non-vanishing, this Home eNodeB is in low load condition.

Step 308, in the time that this centralized node receives this sleep request of this Home eNodeB, this centralized node determines that whether the load of the adjacent Home eNodeB of this Home eNodeB and this Home eNodeB meets the first default loading condition, if not, enters step 309, if so, enter step 310.

Wherein, it is little that the present load of the adjacent Home eNodeB in low load condition is compared in the present load that this first default loading condition can be this Home eNodeB, can be also that the quantity of the adjacent Home eNodeB in low load condition of this Home eNodeB is less than the quantity of the adjacent Home eNodeB in low load condition of other Home eNodeB under this centralized node.

Step 309, in the time that this centralized node determines that the load of the adjacent Home eNodeB of this Home eNodeB and this Home eNodeB does not meet the first default loading condition, centralized node sends and forbids dormancy response to this Home eNodeB.

Wherein, this forbids that dormancy response represents to forbid that this Home eNodeB starts dormancy.

Step 310, in the time that this centralized node determines that the load of the adjacent Home eNodeB of this Home eNodeB and this Home eNodeB meets the first default loading condition, centralized node sends and allows dormancy response to this Home eNodeB.

Wherein, this permission dormancy response represents to allow this Home eNodeB to start dormancy.

Step 311, receive after this permission dormancy response when this Home eNodeB, this Home eNodeB is determined the adjacent Home eNodeB identical with self access module that meets the second default loading condition.

Wherein, this second default loading condition is that load is 0, or load is greater than current low load-threshold and is less than default overload threshold, and this default overload threshold can and need to arrange flexibly according to practical experience, for example, this default overload threshold can be maximum load value.This Home eNodeB is recorded in the adjacent home base station access mode that can be connected with self in station list.

Subscriber equipment (the UE that step 312, this Home eNodeB access according to self, User Equipment) on the each adjacent Home eNodeB that carries of detectable signal information send signal to noise ratio corresponding to detectable signal, in the adjacent Home eNodeB of determining, select the maximum corresponding adjacent Home eNodeB of signal to noise ratio, as target Home eNodeB.

In this step, this Home eNodeB is in the time preparing to start dormancy, send triggering signal to adjacent Home eNodeB, this triggering signal sends downlink detecting signal for triggering adjacent Home eNodeB near UE, when the UE under this Home eNodeB receives after detectable signal, this UE sends this detectable signal information to this Home eNodeB, and this detectable signal information is carried the signal to noise ratio size of this detectable signal.This Home eNodeB can be selected the maximum corresponding adjacent Home eNodeB of signal to noise ratio in adjacent base station definite in step 311, and as target Home eNodeB, the UE that self can be accessed for follow-up this Home eNodeB is switched to this target Home eNodeB.

Step 313, in the time that the load of this target Home eNodeB of determining is 0, this Home eNodeB sends the information of waking up that target Home eNodeB is waken up to centralized node.

In this step, the load of this target Home eNodeB be 0 this target Home eNodeB in resting state.

Step 314, wake up after information when centralized node receives this, this centralized node determines whether current network idling-resource free is not more than default network extra spare resource, if not, enters step 315, if so, enters step 316.

Wherein, this default network extra spare resource can and need to arrange flexibly according to practical experience.

Step 315, in the time that definite current network idling-resource is greater than default network extra spare resource, this centralized node forbids forwarding to this target Home eNodeB the information of waking up.

Step 316, in the time that definite current network idling-resource is not more than default network extra spare resource, this centralized node forwards to this target Home eNodeB the information of waking up.

Current network idling-resource is not more than default network extra spare resource, illustrates that network is busier, now allows wake up target Home eNodeB.

Step 317, wake up after information when target Home eNodeB receives this, stop dormancy and send and waken response up to this Home eNodeB by this centralized node.

Step 318, wake up after response when this Home eNodeB receives this, sent UE handover request to this target Home eNodeB.

Wherein, this handover request is carried the UE that this Home eNodeB will switch, concrete, the signal to noise ratio that UE in this Home eNodeB can be sent to upward signal is arranged from small to large, before selecting, the UE of default number of handovers is as the UE that will switch, this default number of handovers can and need to arrange flexibly according to practical experience, makes except the UE that will switch, and the remaining UE of Home eNodeB is greater than current low load-threshold and is less than default overload threshold.

Step 319, this target Home eNodeB are processed the UE switching, and are the UE service of switching.

Step 320, in the time that the load of this target Home eNodeB of determining is greater than current low load-threshold and be less than default overload threshold, Home eNodeB sends UE handover request to this target Home eNodeB, and enters step 319.

Between above-mentioned steps 313-319 and step 320, there is no strict sequencing.

Step 321, in the time that this Home eNodeB determines that present load is greater than this current low load-threshold and present load and is greater than default overload threshold, be identified for the target Home eNodeB of the UE that will switch the away service of this Home eNodeB.

In this step, specifically can adopt the mode in step 311-312 to determine this target Home eNodeB, not repeat them here.Default overload threshold is greater than current low load-threshold.

Step 322, in the time that the load of this target Home eNodeB of determining is 0, this Home eNodeB is determined the whether all dormancy of adjacent Home eNodeB, if so, execution step 313-319, if not, execution step 320.
