Embodiment
For above-mentioned purpose, the feature and advantage that make the application can become apparent more, below in conjunction with the drawings and specific embodiments the application is described in further detail.
When prior art was carried out the residential quarter switching at needs, subscriber equipment can be measured each adjacent area of residential quarter, place by neighborhood region correlation chart.But, because there is unbalanced phenomenon in the load of each residential quarter in the LTE network, resident subscriber equipment in a large number in some residential quarter, only resident subscriber equipment seldom in some residential quarter.This has just caused the unbalanced of resource distribution, the residential quarter possibility inadequate resource that resident subscriber equipment is too much, and a lot of resources have been wasted in the very few residential quarter of resident subscriber equipment.
Subscriber equipment is not paid close attention to the load of residential quarter, as long as described residential quarter is in the neighborhood region correlation chart of residential quarter, subscriber equipment place, subscriber equipment will be measured and report, if the too much residential quarter of base station selected resident subscriber equipment this moment is as Target cell, then subscriber equipment is when switching, because the inadequate resource of residential quarter, handoff failure possibly, the success rate of switching is lower.And, even handover success, because the inadequate resource of residential quarter, the quality of service of subscriber equipment also is difficult to be guaranteed.
Based on the problems referred to above, the preprocess method that the application provides a kind of residential quarter to switch, can from described neighborhood region correlation chart, delete the adjacent area that load is excessive, when subsequent user equipment is measured the adjacent area in the described neighborhood region correlation chart, can not measure the excessive adjacent area of load, then the excessive adjacent area of load can not become Target cell, thereby has improved the success rate of switching, and load that can balanced each residential quarter guarantees carrying out professional in the residential quarter.
With reference to Fig. 1, provided the preprocess method flow chart that switch the described a kind of residential quarter of the embodiment of the present application.
Because there is unbalanced phenomenon in the load of each residential quarter, resident subscriber equipment in a large number in some residential quarter, only resident subscriber equipment seldom in some residential quarter.For this kind phenomenon, in order to make the cell load in the network balanced as far as possible, guarantee the success rate when switch the residential quarter, the application has configured the load thresholding of adjacent area as Target cell, and can described load thresholding be become one of standard of Target cell as weighing the adjacent area.
Wherein, described load thresholding is the maximal workload of Target cell, and namely when the load of adjacent area surpassed described load thresholding, described adjacent area can not be as Target cell.
In the LTE network, there is neighborhood region correlation chart the base station, has identified the relation of LTE network small area in the described neighborhood region correlation chart, comprising: belong to the residential quarter of this base station, and the adjacent area of described residential quarter.Described is the residential quarter adjacent with this residential quarter, as adjacent on the geographical position.
Therefore, can then obtain the neighborhood region correlation chart of this base station for the base station of residential quarter, subscriber equipment place, then the base station obtains each adjacent area of the residential quarter of this base station from described neighborhood region correlation chart, then measures the information on load of described adjacent area.Wherein, described information on load comprises resource utilization and transmission load etc.
Whether step 103 detects the information on load of adjacent area greater than described load thresholding;
After obtaining the information on load of adjacent area, just the information on load of adjacent area can be compared in described load thresholding, can become Target cell to judge described adjacent area.
Therefore need whether to detect the information on load of adjacent area greater than described load thresholding, if not, the information on load that is the adjacent area is not more than described load thresholding, then the information on load of described adjacent area does not surpass the maximal workload of Target cell, described adjacent area can be used as Target cell, and need not carry out any operation this moment.
If namely the information on load of adjacent area is greater than described load thresholding, then the information on load of described adjacent area has surpassed the maximal workload of Target cell, and described adjacent area can not be as Target cell, follow-up execution in step 14.
Because the base station be measured and be reported to subscriber equipment need to each adjacent area in the neighborhood region correlation chart when carrying out the residential quarter switching, the base station further selects an adjacent area as Target cell according to preset rules again.After judging that the adjacent area can not be as Target cell, for the load of balanced each residential quarter, described adjacent area can be deleted from neighborhood region correlation chart, subsequent user equipment just can not measured described adjacent area carrying out the residential quarter when switching, and described adjacent area just can not become Target cell.
After above-mentioned measurement, detecting, can not be as the adjacent area of Target cell.From neighborhood region correlation chart, after the deletion, just consist of the neighborhood region correlation chart that upgrades this moment, do not comprised information on load in the neighborhood region correlation chart of described renewal greater than the adjacent area of load thresholding.
After having consisted of the neighborhood region correlation chart that upgrades, can be by the neighborhood region correlation chart of broadcast message issue renewal.Subscriber equipment during follow-up the switching, can not measured information on load greater than the adjacent area of load thresholding after receiving the neighborhood region correlation chart of renewal, thereby can be in the burden that increases the larger adjacent area of load.And then so that each cell load in the network is relatively balanced, deleted the adjacent area of information on load greater than the load thresholding in the neighborhood region correlation chart simultaneously after, has reduced the adjacent area that subscriber equipment will be measured, and has also just reduced simultaneously the waste of resource.
In sum, the application has configured the load thresholding of adjacent area as Target cell, and can described load thresholding be become one of standard of Target cell as weighing the adjacent area.Then obtain the information on load of each adjacent area in the neighborhood region correlation chart of residential quarter, subscriber equipment place, at the information on load of adjacent area during greater than described load thresholding, the described adjacent area of deletion from described neighborhood region correlation chart, and consist of the neighborhood region correlation chart that upgrades.Therefore do not comprise information on load greater than the adjacent area of load thresholding in the neighborhood region correlation chart that upgrades, subsequent user equipment is when measuring the neighborhood region correlation chart of the renewal by broadcast message issue, can not measure information on load greater than the adjacent area of load thresholding, thus can be in the burden that increases the larger adjacent area of load.And then so that each cell load in the network is relatively balanced, deleted the adjacent area of information on load greater than the load thresholding in the neighborhood region correlation chart simultaneously after, has reduced the adjacent area that subscriber equipment will be measured, and has also just reduced simultaneously the waste of resource.
Preferably, described information on load comprises: resource utilization and transmission load, wherein, described resource utilization is the resource utilization of residential quarter, comprises Physical Resource Block (Physical Resource Block, PRB) accounting, number of users etc.Described transmission load is the transmission load condition of residential quarter, such as S1 bandwidth occupancy ratio.Certainly, described information on load comprises that also hardware resource takies situation, CPU running rate etc., and the application does not do restriction to this.
Wherein, described PRB accounting can be divided into two kinds of uplink and downlink, and the radix of up PRB accounting is generally 96prb, if wherein take 10prb, then the PRB accounting is 10/96; The radix of descending PRB accounting is generally 100prb, even wherein take 10prb, then the PRB accounting is 10/100=10%.
Certainly, the radix of PRB accounting is variable, and in the implementation, the radix of described PRB accounting can be configured according to the resource of system.
Described S1 is the initial bandwidth of setting up, or is called the bandwidth of planning.
Because can described load thresholding be to weigh the adjacent area become one of standard of Target cell, therefore corresponding to the information on load of adjacent area, described load thresholding also comprises: based on the load thresholding of resource utilization and the load thresholding of loading based on transmission.
Adjacent area in the neighborhood region correlation chart can obtain by modes such as physics and logics, as, the adjacent area of residential quarter, subscriber equipment place may be the residential quarter geographically adjacent with residential quarter, subscriber equipment place, also may be the residential quarter of repeatedly communicating by letter with residential quarter, subscriber equipment place.Therefore, a residential quarter and his adjacent area may belong to same base station in the neighborhood region correlation chart, also may belong to different base station, and the below discusses in two kinds of situation:
