Embodiment
The present invention is directed to the TD-SCDMA technology of not supporting that detected set is measured, under the prerequisite that is no more than the moving table measuring ability, how to find effectively that adjacent area leakage allocation problem has proposed a solution.Its basic ideas are following:
Because travelling carriage has restriction to measurable adjacent area maximum number, and which adjacent area travelling carriage is specifically measured and is decided through the neighboring BS information tabulation that measurement control message brings travelling carriage according to network side; The neighboring BS information tabulation of network side is provided by network planning personnel and disposes through network management system; And network planning personnel are difficult to obtain enough information at the network planning initial stage and confirm that which adjacent area should be measured, but which adjacent area possibly need measured according to a preliminary estimate.Therefore, in the Neighboring Cell List configuration information of network management system, increase a nearby region measurement type field, indicate this adjacent area " must be measured " or " maybe be measured "; If the nearby region measurement type field is configured to " must measured ", then this nearby region measurement must cover in the neighboring BS information tabulation of measurement control message and send to travelling carriage; If this field configuration is " maybe be measured ", then its measurement is done one's best.
If it is measured that network planning personnel confirm that certain adjacent area needs, then it is added in the corresponding Neighboring Cell List, its nearby region measurement types value is configured to " must be measured "; If it is measured to think that certain adjacent area possibly need, but uncertain, then it is added in the corresponding Neighboring Cell List, its nearby region measurement types value is configured to " maybe be measured "; If it is measured to confirm that certain adjacent area does not need, then it is not added in the corresponding Neighboring Cell List; Wherein neighbor cell configuration restriction: " nearby region measurement type " property value of same sub-district is no more than 32 for the homogeneous-frequency adjacent-domain number of " must be measured ", and alien frequencies adjacent area number is no more than 32, and the adjacent area number is no more than 32 between system.

When needs are sent out the different-frequency measure control messages to travelling carriage; At first the adjacent area (adjacent area number be designated as Nd) of nearby region measurement types value in the alien frequencies adjacent area in the Neighboring Cell List of this sub-district for " must be measured " is filled in the neighboring BS information tabulation in the measurement control message, 32-Nd adjacent area is filled in the neighboring BS information tabulation in the measurement control message before from " the alien frequencies nearby region measurement priority query " of current area, taking out then; And this 32-Nd adjacent area is inserted into " alien frequencies nearby region measurement priority query " end again according to going out advanced principle earlier.
When needs are sent out system's measurements control messages to travelling carriage; At first with in the Neighboring Cell List of this sub-district between system in the adjacent area nearby region measurement types value from " the nearby region measurement priority query between system " of current area, take out preceding 32-Nd adjacent area then and be filled into during neighboring BS information in the measurement control message tabulates for the adjacent area (the adjacent area number is designated as Nd) of " must measured " is filled in the neighboring BS information tabulation in the measurement control message; And this 32-Nd adjacent area is inserted into " nearby region measurement priority query between system " end again according to going out advanced principle earlier.
After measuring end, travelling carriage is given network side with reporting measuring result.
After network side is received the measurement report that travelling carriage reports, be the event measurement report that trigger the adjacent area of " must be measured ", carry out switch decision the nearby region measurement type; To the nearby region measurement type is the event measurement report of the adjacent area triggering of " maybe be measured "; Extract measurement result [" event id "; " current area ID: measured value "; " trigger the Target cell ID of measurement report: Target cell measured value "] message, and send to the backstage with the form of notice and preserve, supply that the network optimization personnel read, inquiry is so that carry out adjacent area configuration optimization; Carrying out switch decision then handles.
If the court verdict of network side is for switching, then send switching command to travelling carriage.
Travelling carriage carries out the Serving cell hand-off process after receiving switching command, sends handoff completion message then and gives network side, is carried out the processing of wireless network side by network side.
