A kind of method for optimizing configuration of household base station that the embodiment of the invention provides improves to the workflow of Home eNodeB after the self-configuring process through prior art gets into normal operating conditions.Realize changing when causing abnormal conditions occurring when external environment condition, Home eNodeB can be timely and effectively reach through the change configuration parameter to be avoided because problem such as conversation loss, the delivery flow rate that interference causes be low.
A kind of method for optimizing configuration of household base station that the embodiment of the invention provides, as shown in Figure 2, comprising:
The interference level value of step S201, Home eNodeB period measurement common signal channel.
Get into the Home eNodeB of normal operating conditions, on the basis of existing operation flow, under the state of free time, periodically start and measure flow process, measure the interference level value of common signal channel; The interference level value includes but not limited to level value, carrier/interface ratio.The duration of a measuring period can be 1 hour or 2 hours.
Step S202, be not less than the time time-delay of setting, start and intercept flow process, obtain intercepted result when threshold value and duration that the interference level value that measures is not less than setting.
The result who intercepts that Home eNodeB gets access to comprises: on every side the cell id of each sub-district, frequency, scrambler, received signal code power (Received Signal Code Power, RSCP) value and Carrier interference ratio (Carrierto Interference, C/I) etc.
Step S203, Home eNodeB use the configuration parameter of determining according to intercepted result to carry out self-configuring again.
Home eNodeB carries out definite mode of the configuration parameter of self-configuring again; Can preestablish is directly according to the result who intercepts who gets access to and the algorithm of setting by Home eNodeB; Calculate and determine the mode of configuration parameter; Or intercepted result is reported the Home eNodeB management server by Home eNodeB, after calculating and determine configuration parameter by the Home eNodeB server, return to the mode of Home eNodeB again.
Certainly; Home eNodeB management server in the embodiment of the invention is the functional entity that can realize confirming configuration parameter; Its concrete title can also have other multiple form of presentations, and configuration server etc. for example is as long as can realize confirming the function of configuration parameter; Do not break away from protection scope of the present invention, the embodiment of the invention does not limit this.
To specify the process of calculating and definite configuration parameter, this process can directly be accomplished by Home eNodeB below, also can be accomplished according to the intercepted result that receives by the Home eNodeB management server.As shown in Figure 3, comprising:
Step S301, calculate that Home eNodeB listens to respectively around RSCP value and the weighting sum of C/I of each sub-district.
Step S302, the weighting sum of each sub-district of calculating is sorted.
Step S303, choose the frequency of the first maximum sub-district of the weighting sum of RSCP value and C/I, and choose the scrambler with different other sub-districts of the scrambler of first sub-district; Frequency of choosing and scrambler are confirmed as the configuration parameter that Home eNodeB carries out self-configuring again.
Data instance in the following table 1, table 1 are instances that calculates and sort according to the Home eNodeB intercepted result.Be that (RSCP C/I) is the weighting sum of RSCP value and C/I for the function f of parameter with RSCP and C/I in the table 1.
Table 1
Can find out that from last table 1 (RSCP, first C/I) the maximum sub-district is sub-district 5 to f, chooses the frequency of its frequency as the self-configuring again of Home eNodeB.The reason of choosing like this is that (RCSP C/I) shows that more greatly its interference level is more little because of f.
When selecting scrambler, the scrambler of choosing with different other sub-districts of the scrambler of first sub-district (sub-district 5) 23 gets final product, and for example chooses the scrambler that sub-district 18 employed No. 5 scramblers carry out self-configuring again in the table 1 as Home eNodeB.
In the embodiment of the invention, it is multiple to confirm that algorithm that family's Home eNodeB carries out frequency and the scrambler of self-configuring again can have, and that is to say that (RSCP, value C/I) comprises the weighting sum that is not limited to RSCP value and C/I to f.
Home eNodeB is accomplished after the process of self-configuring again, gets into operating state once more, continues periodically the interference level value to be measured.
When externally environment changed to Home eNodeB formation interference, the real-time service of this Home eNodeB and non-real time service also may take place unusually because of disturbing.Real-time service refers to the business that service attribute is conversation class (conversational) and stream type (streaming), for example business such as phone, visual telephone, Streaming Media.It is professional and conversational class (interactive) business of background classes (background) that non-real time service refers to service attribute, business such as for example FTP download, web page browsing.
When the real-time service of family base station and non-real time service take place when unusual; On the basis of abovementioned steps S101～step S103; The method for optimizing configuration of household base station that the embodiment of the invention provides also need start the self-configuring flow process of Home eNodeB monitoring these two types professional generations when unusual; Make Home eNodeB to remove and disturb that the handling process of Home eNodeB describes when unusual to taking place when real-time service and non-real time service respectively below through self-configuring again.

Step S402A, Home eNodeB use the configuration parameter of determining to carry out self-configuring again.
The unusual release concrete concept of real-time service be meant since objective factor discharge professional, rather than the user initiatively discharge should business, for example call drop etc. appears in the user.The Home eNodeB judgement receives and issues Radio Resource control (Radio Resource Control; When the Release Cause field of RRC) carrying in connection release (RRC Connection Release) message is Unspecified, just can confirms and unusual release to have taken place business.
When Home eNodeB monitors the situation of the unusual release of real time business generation; Preferably; When this Home eNodeB does not have other real-time services; Just beginning to carry out the flow process of self-configuring again, do not start when why being chosen in other real-time services of nothing, is in order to avoid implementing the influence of configuration optimization process to the original business of Home eNodeB as far as possible.
In step S401A, the detailed process that Home eNodeB calculated and determined configuration parameter is following: calculate in the last intercepted result of record the received signal code power value of each sub-district and the weighting sum of Carrier interference ratio and ordering respectively; Computational methods can be identical with the computational methods among the step S301.
Choose the frequency of weighting sum, and choose the scrambler with different other sub-districts of the scrambler of this second sub-district inferior to peaked second sub-district;
Frequency of choosing and scrambler are confirmed as the configuration parameter that this Home eNodeB carries out self-configuring again.
Still with the data instance explanation of table 1, (RSCP C/I) calculates according to the last intercepted result, so, from table 1, can find out, (RSCP is sub-district 6 inferior to peaked second sub-district C/I) to f to suppose f in the table 1.Choose the frequency of the frequency of sub-district 6 as Home eNodeB self-configuring again.
Choose the scrambler of other different sub-districts of the scrambler that uses with sub-district 6 simultaneously, for example sub-district 8 No. 10 scramblers scrambler of carrying out self-configuring as Home eNodeB again.
In the embodiment of the invention, to real-time service unusual situation about discharging appears, the method that Home eNodeB can also adopt fixing frequency to intercept, and idiographic flow comprises shown in Fig. 4 B:
Step S401B, when family's base station monitors when unusual release conditions appears in real-time service, the selected part frequency is intercepted, and determines configuration parameter according to the result who intercepts;

| Sub-district ID | Frequency | Scrambler | f(RSCP、C/I) |
| 6 | 5 | 13 | 68 |
| 8 | 3 | 10 | 63 |
| 10 | 1 | 3 | 58 |
