Description
Technical field
The present invention relates to wireless communication technology field, particularly a kind of method of power self-optimizing, system and equipment.
Background technology
Reducing the complexity of operational administrative work, reduce operation maintenance cost, is an urgent demand of common carrier.In follow-on network, hope to reduce the manual work of the network planning and Operation and Maintenance and participate in through introducing the mechanism of self-organization of network, reduce the construction and the operation cost of network.Just under such background; E-UTRA (Evolved UMTS Terrestrial Radio Access; The UMTS terrestrial wireless access of evolution) SON (the Self Organizing Networks of system; Self-organizing network) characteristic is studied as a job of 3GPP (3rd Generation Partnership Project, 3G (Third Generation) Moblie standardization body) subject under discussion.The SON technology comprised self-configuring, self-optimizing and cured certainly, and self-optimizing is key property wherein.

Cell selecting has two kinds of processes, is respectively that initial cell is selected and the stored information cell selecting:
The stored information cell selecting needs the stored information of carrier frequency and optional cell parameter information.Parameter can be with coming from former measuring control information or former detected sub-district.If the discovery suitable cell, UE (terminal) is with resident.If do not find suitable cell, UE will start the initial cell selection course.
Initial cell selects need not the prior information of E-UTRA carrier wave RF (Radio Frequency, radio frequency) channel.UE will remove to find suitable cell according to all the RF channels in the ability scanning E-UTRA frequency band of oneself.On each carrier wave, UE only need search for the strongest sub-district.In case the discovery suitable cell, this sub-district is with selected.
The selection of sub-district need be satisfied the demand of signal strength signal intensity and signal quality simultaneously, when satisfying these demands, can choose this sub-district.Because possibly starting shooting, a MUE (grand terminal) gets into the cell selecting process in the stronger geographic area of HeNB (Home eNodeB) signal; Possibly cause selecting HeNB to attempt inserting immediately after the start; But this UE is not the member UE of this HeNB, and UE attempts will selecting other sub-districts to insert behind the access failure.
Cell reselection process need sort to the sub-district that UE measures, and UE carries out the gravity treatment to the best sub-district of signal strength signal intensity.When the best sub-district of this signal strength signal intensity is the non-member HeNB of UE, UE will not consider that this sub-district is the candidate cell of gravity treatment, and on frequently, continue to consider other sub-districts.If the CSG ID of HeNB (closing the group id with the contracted user) is not among the CSG of UE white list, UE will can normally not reside in this HeNB, but continue to consider that other sub-districts with on the frequency are the candidate cell of its gravity treatment.
For the situation of CSG (Close Subscriber Group closes and contracted user group), UE1 belongs to grand station, and Home eNodeB only can authorization of service CSG user, because UE2 is CSG user, so can the authentication access to family base station.When UE1 is positioned at the coverage of Home eNodeB; Because UE1 is different from UE2; Be not the CSG user who authorizes, even the Home eNodeB signal strength signal intensity is higher than the signal strength signal intensity at grand station far away, UE1 also can't switch to Home eNodeB and will receive the strong jamming from Home eNodeB.The non-constant of channel condition that so just might cause user UE1 produces call drop, or even can't work.Power distribution method in existing LTE (Long Term Evolution, the Long Term Evolution) agreement, the signal quality of this sub-district carries out power control owing to can not disturb perhaps through the adjacent area of reporting of user, can't solve the descending interference problem under the above-mentioned situation.
