Whether the maximum in signal strength threshold value when 202, the network equipment judges that UE reports 1a event and signal strength threshold value when reporting 1b event is greater than preset signal strength value, if be greater than, then performs step 203, otherwise performs step 204;
203, the network equipment is that UE configures a PO value;
When maximum in signal strength threshold value when UE reports 1a event and signal strength threshold value when reporting 1b event is greater than preset signal strength value, illustrate that the channel quality of main Serving cell and cooperation cell differs greatly, now the channel quality of possibility cooperation cell is very poor, the network equipment can configure a larger PO value for UE, an i.e. PO value, to ensure that main Serving cell and cooperation cell can receive and the HS-DPCCH that returns of demodulation UE smoothly.
204, the network equipment is that UE configures the 2nd PO value.
When maximum in signal strength threshold value when UE reports 1a event and signal strength threshold value when reporting 1b event is less than or equal to preset signal strength value, illustrate that main Serving cell differs very little with the channel quality of cooperation cell, the channel quality of main Serving cell and cooperation cell is all relatively good comparatively speaking, now the network equipment can configure a less PO value for UE, i.e. the 2nd PO value, like this under ensureing that main Serving cell and cooperation cell can receive the HS-DPCCH prerequisite that also demodulation UE returns smoothly, save the power consumption of UE.
Refer to Fig. 3 below, the method for the present embodiment comprises:
301, when UE is the multithread UE across base station, the network equipment obtains the scene information of UE;
In the present embodiment, can think that the scene information of the UE that the network equipment obtains is the Ec/No of Ec/No and the UE of UE in main Serving cell in cooperation cell, namely UE receives the signal quality that the signal quality of main Serving cell and UE receive cooperation cell.
302, the network equipment judges whether the difference of Ec/No and the UE of UE in main Serving cell between the Ec/No of cooperation cell is greater than preset difference value, if so, then performs step 303, otherwise, perform step 304;
303, the network equipment is that UE configures a PO value;
When Ec/No and the UE difference the Ec/No of cooperation cell between of UE in main Serving cell is greater than preset difference value, illustrate that the channel quality of main Serving cell and cooperation cell differs greatly, now the channel quality of possibility cooperation cell is very poor, the network equipment can configure a larger PO value for UE, an i.e. PO value, to ensure that main Serving cell and cooperation cell can receive and the HS-DPCCH that returns of demodulation UE smoothly.
304, the network equipment is that UE configures the 2nd PO value.
When Ec/No and the UE difference the Ec/No of cooperation cell between of UE in main Serving cell is less than or equal to preset difference value, illustrate that main Serving cell differs very little with the channel quality of cooperation cell, the channel quality of main Serving cell and cooperation cell is all relatively good comparatively speaking, now the network equipment can configure a less PO value for UE, i.e. the 2nd PO value, like this under ensureing that main Serving cell and cooperation cell can receive the HS-DPCCH prerequisite that also demodulation UE returns smoothly, save the power consumption of UE.
Refer to Fig. 4 below, the method for the present embodiment comprises:
401, when UE is the multithread UE across base station, the network equipment obtains the scene information of UE;
In the present embodiment, can think the scene information of the UE that the network equipment obtains is whether main Serving cell and cooperation cell have HS-DPCCH interference cancellation ability.
402, the network equipment judges whether main Serving cell and cooperation cell all have HS-DPCCH interference cancellation ability, if so, then performs step 403, otherwise, perform step 404;
403, the network equipment is that UE configures a PO value;
If main Serving cell and cooperation cell all have HS-DPCCH interference cancellation ability, then illustrate that the demodulation performance of main Serving cell and cooperation cell is all relatively good, therefore a less PO value can be configured for UE, i.e. the 2nd PO value, like this under ensureing that main Serving cell and cooperation cell can receive the prerequisite of the HS-DPCCH that also demodulation UE returns smoothly, save the power consumption of UE.
404, the network equipment is that UE configures the 2nd PO value.
If main Serving cell and/or cooperation cell do not have HS-DPCCH interference cancellation ability, then illustrating has at least the demodulation performance of a community bad, therefore need for UE configures a larger PO value, i.e. the 2nd PO value, to ensure that main Serving cell and cooperation cell can receive and the HS-DPCCH that returns of demodulation UE smoothly.
Refer to Fig. 5, another embodiment of HS-DPCCH PO collocation method of the present invention comprises:
501, when UE is the multithread UE across base station, the network equipment obtains the scene information of UE;
In the present embodiment, can think that the scene information of the UE that the network equipment obtains is the ascending load of main Serving cell and cooperation cell.
502, the network equipment judges whether the ascending load of main Serving cell and cooperation cell is all less than default load threshold, if so, then performs step 503, otherwise, perform step 504;
503, the network equipment is that UE configures a PO value;
The ascending load of main Serving cell and cooperation cell is all less than default load threshold, illustrate that the idling-resource of main Serving cell and cooperation cell is more, accordingly, UE can resource also many, now can configure a larger PO value for UE, i.e. the 2nd PO value, fully to ensure that main Serving cell and cooperation cell can receive and the HS-DPCCH that returns of demodulation UE smoothly.
504, the network equipment is that UE configures the 2nd PO value.
The ascending load of main Serving cell and/or cooperation cell is less than default load threshold, then illustrating has at least the idling-resource of a community less, accordingly, UE can resource also less, now can configure a less PO value for UE, i.e. the 2nd PO value, ensures that main Serving cell and cooperation cell can receive and the HS-DPCCH that returns of demodulation UE smoothly.
Above-mentioned several embodiment is for UE configures the method for PO value when being single a certain category information with the scene information of the UE of network equipment acquisition, in actual applications, above-mentioned a few category information can also be combined for UE configures PO value.
Particularly, when the scene information of UE meets any one condition following, or during any number of condition, for UE configures a PO value; When the scene information of UE does not all meet following condition, for UE configures the 2nd PO value; Described condition comprises:
