Description
Technical field
The present invention relates to Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, WCDMA) wireless telecommunication system, relate in particular to the method for a kind of adjacent area configuration optimization in the WCDMA wireless telecommunication system, the invention provides a kind of unusual method of this neighbor cell configuration of finding for network optimization personnel reference, and provide a kind of radio network controller when this neighbor cell configuration is unusual, to select the method for adjacent area to be measured.
Background technology
The service continuity that guarantees the mobile subscriber is a basic function of honeycomb mobile communcations system, and the switching of travelling carriage Serving cell is the main means that guarantee service continuity.
In the honeycomb mobile communcations system, travelling carriage will carry out the Serving cell switching and just need measure the wireless quality of Target cell.Because the restriction of moving table measuring ability and efficiency of measurement, 3GPP agreement regulation: travelling carriage can mostly be 32 most in the interior adjacent area of simultaneously-measured frequency in the WCDMA mobile communcations system, and the adjacent area mostly is 32 most between frequency, and the adjacent area is maximum 32 between system.Therefore, radio network controller need be a mobile station in selecting Target cell to be measured for the neighboring BS information of these cell configuration according to the sub-district in the current Active Set and network planning personnel.
Radio network controller generally is to select the adjacent area of current service cell as sub-district to be measured when selecting Target cell to be measured.Because the WCDMA system supports soft handover, so current service cell has the union that a plurality of, to be measured Target cells is generally the adjacent area of current service cell.
Network planning personnel dispose according to the sub-district when configuring adjacent cell information, network planning personnel or neighbor cell configuration instrument can guarantee that the adjacent area number of each sub-district is no more than the measurable maximum number of travelling carriage, but cannot guarantee that the adjacent area union number of sub-district in the Active Set is no more than the measurable maximum number of travelling carriage.
Chinese patent application number has been described the method for automatic maintenance neighborlist in a kind of cdma system for the patent of CN02110634.7, and this method just is used for handling the adjacent area and leaks allocation problem, and it is powerless to put problem for aforesaid adjacent area polygamy.
Chinese patent application number has been described a kind of method of monitoring pilot frequency contamination for the patent of CN02136993.3, this method is to measure a solution that has in the reported result that a plurality of cell quality are all fine may be to ready-made interference the each other the time at the sub-district wireless quality, the prerequisite that this patent realizes is that the sub-district neighbor cell configuration is normal, so foregoing problems is the prerequisite that this patent realizes.
Chinese patent application number has been described a kind of automatic optimization method of neighboring BS relationship for the patent of CN03134779.7, this patent mainly is the heavy and a kind of system Automatic Optimal strategy that proposes of workload when optimizing in the adjacent area at network optimization personnel, its limitation is that the sub-district wireless quality measurement report overwhelming majority adopts the mode of reporting events in the WCDMA wireless telecommunication system, and the pilot strength information of all sub-districts of needs when not comprising this patent working in the measurement report of reporting events, therefore can't solve aforementioned adjacent area polygamy puts problem.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of and finds method that neighbor cell configuration is unusual and the effective treating method of radio network controller when this neighbor cell configuration is unusual.
When supporting the WCDMA wireless telecommunication system neighbor cell configuration of soft handover, cannot determine which sub-district may be in the same Active Set, thereby just not know also whether the adjacent area union number that sub-district in the Active Set can or can not occur can surpass the measurable maximum number of travelling carriage; And these unknown quantitys are known when radio network controller is mobile station in selecting Target cell to be measured, whether the union number that can judge adjacent area in the Active Set this moment can surpass the measurable maximum number of travelling carriage, if surpass, then send a notification message and tell network optimization personnel that neighbor cell configuration is unusual, carry out adjacent area configuration optimization for network optimization personnel.
The method of the adjacent area configuration optimization in a kind of wireless network environment comprises:
1) radio network controller is a mobile station in selecting Target cell to be measured;
2) radio network controller carries out the wireless quality measurement by measuring control messages notice travelling carriage to Target cell;
3) travelling carriage reports radio network controller with measurement result;
4) radio network controller carries out switch decision, switches if desired then to send switching command to travelling carriage;
5) travelling carriage carries out the Serving cell hand-off process after receiving switching command, sends out handoff completion message then and gives radio network controller.
Wherein step 1) further comprises:
Step (1) judges whether the adjacent area union of sub-district in the Active Set has surpassed the measurable maximum number of travelling carriage, if the adjacent area union of sub-district has surpassed the measurable maximum number of travelling carriage in the Active Set, send then that announcement information---neighbor cell configuration is unusual, the adjacent area union of sub-district surpasses the measurable maximum number of UE (Active Set sub-district ID tabulation) in the Active Set;
Step (2) is selected Target cell to be measured from the adjacent area of Active Set.
Step (2) further comprises:
(a) if the adjacent area union of sub-district surpasses the measurable maximum number of travelling carriage in the Active Set, then sort according to each adjacent area number of times that each sub-district occurs in Active Set, the adjacent area that occurrence number is many is preferentially measured, as many for occurrence number, then select at random, till selecting the measurable maximum number of a travelling carriage adjacent area;
(b) if the adjacent area union of Active Set sub-district does not surpass the measurable maximum number of travelling carriage, then the adjacent area union of sub-district is Target cell to be measured in the Active Set.
Adopt the method for the invention, can improve the efficient of radio network optimization, improve the wireless performance of system
