Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
Consult shown in Figure 1A, in the present embodiment, mobile communication system comprises at least one network side network element, and this network side network element is determined adjacent area to be deleted in each adjacent area of self administering the sub-district; Described network side network element is deleted isolating of adjacent area described waiting in the Neighboring Cell List of this locality, describedly waits to delete the adjacent area and is not chosen as Serving cell in confinement period.
In actual applications, the network side network element is satisfying is in radio network controller (RNC), base station controller (BSC) or the enhanced base station (eNB) any one.
Consult shown in Figure 1B, in the present embodiment, the network side network element comprises memory cell 100, determining unit 101, processing unit 102, wherein:
Memory cell 100 is used to preserve local Neighboring Cell List;
Determining unit 101 is used for determining adjacent area to be deleted in each adjacent area of present networks side network element administration sub-district;
Processing unit 102 is used at local Neighboring Cell List described waiting being deleted isolating of adjacent area.
In addition, as shown in Figure 1, can also comprise adjustment unit 103 and notification unit 104 in the network side network element, wherein:
Adjustment unit 103 is used at processing unit 102 readjusting the switching priority of other adjacent areas in this Neighboring Cell List after the Neighboring Cell List of this locality is treated deletion the adjacent area isolated;
Notification unit 104 is used at processing unit 102 after the Neighboring Cell List of this locality is treated deletion the adjacent area isolated, and each portable terminal in the notice present networks side network element compass of competency stops adjacent area described to be deleted is measured.
Based on above-mentioned network side network element, to consult shown in Figure 2ly, in the present embodiment, the network side network element is as follows to the detailed process that local Neighboring Cell List upgrades:
Step 200: the network side network element is determined adjacent area to be deleted in each adjacent area of self administering the sub-district;
In the present embodiment, it is multiple that portable terminal determines that the method for adjacent area to be deleted has, and comprising:
1, issues the handoff list that comprises number of handovers and handover success rate to portable terminal by operation maintenance center (OMC), network side network element (comprising RNC, BSC or eNB) carries out switch decision based on above-mentioned handoff list, for example, when threshold values that the number of handovers and the handover failure rate of certain adjacent area is lower than setting, classify it as adjacent area to be deleted.
2, the network side network element is measured statistics, it is the measurement that all portable terminals are carried out physical layer in the network side network element indication compass of competency, and add up the number of times that it carries out measuring operation, and classify the adjacent area that measured number of times is lower than setting threshold as adjacent area to be deleted according to the measurement result that portable terminal returns.
3, the network side network element is determined the load of certain adjacent area or disturbs to surpass when setting threshold values, classifies it as adjacent area to be deleted, so that control the scope that its traffic carrying capacity is being born.
Step 210: this adjacent area of network side network element is classified adjacent area to be deleted as, and readjusts in the Neighboring Cell List after the renewal the not switching priority of segregate other adjacent areas.
In the present embodiment, the network side network element comprises radio network controller (RNC), base station controller (BSC) or enhanced base station (eNB), and this adjacent area is deleted from the sorted lists of adjacent area.
Step 220: the network side network element [is for example revised corresponding system information, System information block (SIB4)] and radio resource control information is [(for example, Radio Resource connects reconfiguration message (ReconfigurationRequest, and notify each portable terminal under this sub-district to stop (as level measurement) measured in adjacent area segregate to be deleted RRC)].
According to the regulation of standard 3GPP 25.331 or 3GPP 36.331, when the network side network element indicated each portable terminal to stop certain adjacent area measured, a cell ID that only needs not carry this adjacent area in the message that issues can be realized.
Step 230: the network side network element is carried out follow-up associative operation according to the renewal result of Neighboring Cell List.
In the present embodiment, after the network side network element is treated deletion the adjacent area isolated, in confinement period, just no longer elect it as Serving cell; On the other hand, waiting to delete in the confinement period of adjacent area, the network side network element can also be carried out following any one associative operation:
1, in Neighboring Cell List, will wait to delete the cell ID deletion of adjacent area.
2, treat the deletion adjacent area and monitor, and when the wireless parameter value of determining to wait to delete the adjacent area rises to setting threshold, stop to isolate, again it is included into the row of optional Serving cell.
3, will not wait to delete the cell ID deletion of adjacent area, and no longer treat the deletion sub-district and monitor, and promptly stop self and wait to delete all information interactions between the sub-district.
In the above-described embodiments, the network side network element can regularly upgrade the Neighboring Cell List of this locality according to the cycle of setting, certain part trigger event also can take place after, the Neighboring Cell List of this locality is upgraded, for example, adjustment of the modification of network side parameter, service distribution and type etc.
In the embodiment of the invention, the network side network element is determined adjacent area to be deleted in each adjacent area of self administering the sub-district; Described network side network element is deleted isolating of adjacent area described waiting in the Neighboring Cell List of this locality, describedly waits to delete the adjacent area and is not chosen as Serving cell in confinement period.Like this, the network side network element is the shielded signal quality sub-district that can not satisfy demand for services automatically just, thereby has improved the execution efficient and the effect of switching judging to a great extent, and then has promoted user experience to a certain extent.
Obviously, those skilled in the art can carry out various changes and modification to the embodiment among the present invention and not break away from the spirit and scope of the present invention.Like this, if these in the embodiment of the invention are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the embodiment among the present invention also is intended to comprise these changes and modification interior.
