Step 620:HeMS adopts remote call-in to download (Download Remote Procedure Call; Be called for short Download RPC) mode (even HeNB initiatively obtains the harmony messages line parameter configuration of going forward side by side); Indication HeNB through the designated storage location of Type1 management interface in HeMS (as; File server) downloads the CM data that comprise harmony messages, to realize telemanagement to HeNB.
Step 630:HeNB downloads the CM data through the designated storage location of Type1 management interface from HeMS, and from the CM data of downloading, obtains harmony messages, and returns the CM data to HeMS and download the completion indication.
At this moment, just HeNB can accomplish parameter configuration in this locality based on the harmony messages of downloading, as, carry out sub-frame configuration, carry out the frequency domain resource configuration, carry out power control or the like.
Being different from the foregoing description, consulting shown in Figure 7ly, in the embodiment of the invention, is HeMS with the NE management entity, and little base station is that HeNB is an example, and HeMS is elaborated to the second method flow process that HeNB issues harmony messages:
Step 700:HeMS obtains the preset harmony messages of corresponding HeNB.
In the present embodiment, above-mentioned harmony messages is included in download configuration management (CM) data.
Step 710:HeNB registers and sets up session connection in HeMS.
In the practical application, do not limit the execution sequence of above-mentioned steps 700 and step 710, also can first execution in step 710, execution in step 700 again, and perhaps both executed in parallel repeat no more at this.
In the embodiment of the invention, preferably, the communication unit 41 among the HeMS can be set to the TR-069 manager, and through this TR-069 manager set up and HeNB between session connection, and preset harmony messages is mail to HeNB through this TR-069 manager.
Step 720:HeMS adopts remote call-in parameter configuration (Set Parameter Value RPC) mode (be HeMS initiatively issue harmony messages and be configured); The CM data that will comprise harmony messages are sent to HeNB through the Type1 management interface, to realize the telemanagement to HeNB.
Step 730:HeNB receives the CM data that HeNB sends, and from these CM data, obtains harmony messages, and returns remote call-in parameter configuration response (SetParameterValueResponse) to HeMS.
At this moment, just HeMS can directly carry out parameter configuration based on the harmony messages that sends to HeNB to HeNB, as, carry out sub-frame configuration, carry out the frequency domain resource configuration, carry out power control or the like.
In the embodiment of the invention; Owing to set up the function of sending harmony messages through the Type1 management interface to HeNB for the NE management entity; Therefore; Need be the corresponding harmony messages of NE management physical arrangements, in the embodiment of the invention, harmony messages can comprise a kind of or combination in any in subframe configuration information, power control information, the frequency domain resource occupied information.Wherein,

2) MBSFN sub-frame property indication; This is designated as when using the MBSFN configuration; Be added on data division and whether transmit the differentiation indication of data, be used to represent that current MBSFN subframe is the real many ripples of multimedia broadcasting professional (Multimedia Broadcast Multicast Service, MB SFN subframe MBMS); Or the pseudo-MBSFN subframe of the free of data transmission in the time domain coordination, and the pseudo-MBSFN subframe that transfer of data is arranged.Wherein, its design in harmony messages of subframe service attribute indication is as shown in table 2 for example:
If only adopt the fake-MBSFN coordination mode, can multiplexing existing MBSFN subframe indicate form, the design of the harmony messages that newly adds is following:
Table 2
3), time domain coordinates subframe pattern (pattern) indication, the subframe form that is used to indicate HeNB on which subframe, to adopt low interference (as, data division has subframe and the fake-MBSFN subframe of CRS).Wherein, it is as shown in table 3 for example that time domain is coordinated the design of subframe pattern indication in harmony messages:
Table 3
Secondly, when power configuration information is set, can in subframe configuration information, comprise the descending power Control Parameter; Or/and uplink power control parameter; Be used to indicate whether to open descending power control, power controlled target signal to noise ratio, uplink power control parameters optimization etc.Wherein,
The design of descending power Control Parameter in harmony messages is as shown in table 4 for example:
Table 4
And the design of uplink power control parameter in harmony messages is as shown in table 5 for example:
Table 5
Once more, when the frequency domain resource occupied information is set, can in the frequency domain resource occupied information, comprise the carrier wave that HeNB takies, amount of bandwidth, bandwidth region or the like; Wherein, the design of frequency domain resource occupied information in harmony messages is as shown in table 6 for example:
Table 6
In sum, in the embodiment of the invention, for the NE management entity has been set up corresponding function; Make the NE management entity can pass through the Type1 management interface, the harmony messages of little base station is mail to this little base station, thereby make this little base station can in time obtain the harmony messages of self and accomplish parameter configuration; Like this, realized in Hierarchical Network that just time domain is coordinated and power control exactly, and need not increase the quantity of mutual harmony messages; Guarantee the performance of Hierarchical Network, particularly under the situation that does not have X2 interface, realized the timely transmission of harmony messages; Improve covering performance and the data rate in the Hierarchical Network, promoted the reliability and the service quality of Hierarchical Network.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, belong within the scope of claim of the present invention and equivalent technologies thereof if of the present invention these are revised with modification, then the present invention also is intended to comprise these changes and modification interior.
