As shown in Figure 1, one embodiment of the invention proposes a kind of processing method of intelligent antenna beam shaping weights, comprising:
Step S101, structure beam shape-endowing weight value storehouse;
The present embodiment method running environment realizes based on the EMS system, and the beam shape-endowing weight value storehouse is the set of the self-defined beam shape-endowing weight value of many covers standard beam shape-endowing weight value or equipment vendors.
Wherein, the self-defined beam shape-endowing weight value of equipment vendors is according to after antenna physical attribute and the satisfied covering requirement of pretest special scenes, cover broadcast wave bean shaping weights that provide.If this overlaps self-defined beam shape-endowing weight value confirm to be accepted by operator after, can be exchanged into standard smart antenna broadcast wave bean shaping weights.
As mentioned above, the physical attribute of smart antenna comprises at least: antenna producer, antenna type, antenna band, element number of array, array element distance, beamwidth, beam position, antenna gain etc., can in the beam shape-endowing weight value storehouse, determine one group of intelligence beam shape-endowing weight value (corresponding by indexed mode) after these physical attribute combinations of smart antenna.
The standard beam shape-endowing weight value then is according to unified template by operator, the broadcast wave bean shaping weights of each antenna producer of collecting and confirming, compare self-defined beam shape-endowing weight value, standard beam shape-endowing weight value many one " standard weight version number " can support the product standard to import corresponding weights data according to document template.
To the unified management of smart antenna broadcast wave bean shaping weights, need to be with the radio configuration data of the wireless subsystem basis of characterization as resource object.Wireless subsystem by with the interface of telephone traffic network resource management module, the interface of wireless network optimization platform RRM module, the network management interface mode of EMS, or in the mode of manual typing, obtain initialized radio resource data, set up resource model.In follow-up network change process, wireless subsystem is according to the resource changing process, regular update resource data, the consistency of keeping system basic resource data and existing network.
The present embodiment is realized by lower mode when structure beam shape-endowing weight value storehouse:
When the beam shape-endowing weight value storehouse in the EMS system is sky, can be by importing standard beam shape-endowing weight value and/or self-defined beam shape-endowing weight value, structure beam shape-endowing weight value storehouse.
Simultaneously, in this beam shape-endowing weight value storehouse, entirely show according to the full table of different systems configuration standard antenna weights and self-defined antenna weights, and the standard antenna weights are shown to be decomposed into standard weight version number and standard antenna weight table, antenna property table entirely; The full table of self-defined antenna weights is decomposed into self-defined antenna weight table and antenna property table; The antenna property table comprises the antenna property information of self-defined weights and standard weight.
Wherein, self-defined antenna weight table and standard antenna weight table are related with the antenna property table by antenna property ID.That is to say, in self-defined antenna weight table, standard antenna weight table and antenna property table, all include antenna property ID (Index, index) field, take the antenna property id field as index, go to inquire about related data in corresponding self-defined antenna weight table and the standard antenna weight table according to antenna physical attribute in the antenna property table.
In addition, when structure beam shape-endowing weight value storehouse, also be included in and import single mode or multimode weights data in the beam shape-endowing weight value storehouse; Perhaps; from the beam shape-endowing weight value storehouse, derive single mode or multimode weights data; perhaps import and export the weights data with standard weight version number, and by above-mentioned weights data generate that standard antenna weights in the beam shape-endowing weight value storehouse are shown entirely, self-defined antenna weights are shown entirely, standard antenna weight table, self-defined antenna weight table and antenna property table.Thereby finish different systems the antenna beam shape-endowing weight value import and export operation.By the two-way interactive of data message, the weighting parameter in the beam shape-endowing weight value document can be imported in the beam shape-endowing weight value storehouse, also the weights data in the beam shape-endowing weight value storehouse can be exported as the beam shape-endowing weight value data file; Also comprise according to standard weight version number mode and import and export the weights data.
Step S102 carries out the antenna data configuration management based on the beam shape-endowing weight value storehouse to wireless subsystem.
Behind the construction complete of beam shape-endowing weight value storehouse, then can carry out the antenna data configuration management to wireless subsystem based on this beam shape-endowing weight value storehouse, comprise the derivation of beam shape-endowing weight value in configuration to the radio configuration data of wireless subsystem, the radio configuration data, the operation such as synchronous.
Particularly, in the EMS configuration subsystem, when carrying out the wireless data configuration, can in the beam shape-endowing weight value storehouse, retrieve corresponding beam shape-endowing weight value, be applied in certain residential quarter with the beam shape-endowing weight value with correspondence.
At first select the antenna property parameter in the antenna property table from the beam shape-endowing weight value storehouse, such as antenna producer, antenna type, number of antennas, antenna gain, antenna distance etc.
Then according to the antenna property parameter of selecting, retrieval is judged in the self-defined antenna weight table in the beam shape-endowing weight value storehouse or the standard antenna weight table, and whether the antenna property parameter of selection exists; If exist, then retrieve the beam shape-endowing weight value corresponding with wireless subsystem in the self-defined antenna weight table in the beam shape-endowing weight value storehouse or the standard antenna weight table; The beam shape-endowing weight value of correspondence is incorporated in the wireless subsystem radio configuration data of configuration wireless subsystem.
The concrete configuration process is: increase " weights sign " field in the radio configuration subsystem, when selecting self-defined antenna weights or standard antenna weights, upgrade this field.
Behind selected self-defined antenna weights or standard antenna weights, need according to the antenna property parameter of above-mentioned selection and antenna band, antenna distance, antenna gain etc. as combined index, retrieval is judged in corresponding weight table, and whether corresponding antenna weights data (amplitude and phase place) exist.
Can generate data pattern file corresponding to foreground network element according to the radio configuration data at last, loading synchronous is carried out cell signal optimization by the foreground network element according to the beam shape-endowing weight value data and is covered to the foreground network element.
Take the TD-SCDMA standard as example, when physical antenna configures, the following attribute of option and installment successively: antenna producer, antenna model, antenna type, number of antennas, antenna distance, antenna gain.But the selected value of these 6 attributes is retrieved from the beam shape-endowing weight value storehouse when the initialization of interface; After the value of selected this corresponding attribute, need 6 parameters as the retrieval-by-unification condition, to judge the validity of corresponding physics antenna property.
When the configuration wireless area, needing to specify the beam shape-endowing weight value that adopts is standard antenna weights or self-defined antenna weights, behind selected corresponding beam shape-endowing weight value table, select again the wave beam forming parameter of smart antenna: beamwidth, beam direction, antenna band.The value of these three fields also physical attribute parameter of similar 6 smart antennas is the same, shows optional value during initialization.
When above-mentioned 9 parameters as the retrieval-by-unification condition after beam shape-endowing weight value library searching success, the wireless parameter of residential quarter together is saved in the radio configuration data together with 9 search arguments and corresponding beam shape-endowing weight value data (amplitude and phase place).Thereby finish the configuration of the radio configuration data of wireless subsystem.

When carrying out the switching of weights version, need to carry out validity checking, when switching to the standard weight version from self-defined weights version, also need to satisfy following condition: there are two or more standard weight versions in current system; The antenna figuration parameter that current network wireless subsystem configuration data is quoted must exist, and can retrieve corresponding antenna weights data in new weights version.
Take above-mentioned TD-SCDMA standard as example, namely 9 joint index parameters of the beam shape-endowing weight value in the radio configuration data must exist in the weights version before and after switching simultaneously, otherwise can not switch.
After switching the success of weights version, need to upgrade beam shape-endowing weight value amplitude and phase place in the radio configuration data, and upgrade " standard weight version number " and " weights version sign " field of radio configuration data.
