Specific embodiment
Therefore for the cell in different frequency range, current UE is from the larger cell of coverage (macrocell) to coverage
When less cell (Microcell) switches, whether the wireless quality that UE does not have effective means to judge less cell meets wirelessly
Access and require, also with regard to there is no effective ways realizing the load balancing from low frequency cell to high frequency cell.Therefore, in prior art
Target cell quality cannot be now determined that in fact (especially current service cell is low frequency cell, and Target cell is high frequency cell)
In the case of the switching that carries out, do not ensure that the quality of service after switching yet.
In order to solve the above problems, embodiments of the invention propose a kind of according to Serving cell wireless quality judgement adjacent area
Target cell is covered, so really under current location Target cell radio signal quality cell switching method, the method can be with
Solve as radio network controller (Radio Resource Controller, RNC) cannot be judged in Serving cell
The problem that UE is switched over without normal direction adjacent area in the wireless coverage situation of adjacent area.
Embodiments of the invention are described in detail below in conjunction with accompanying drawing.It should be noted that not conflicting
In the case of, the feature in embodiment and embodiment in the application can mutual combination in any.
Accompanying drawing is combined first, and embodiments of the invention one are illustrated.
A kind of cell switching method is embodiments provided, and UE is completed using the method little from Serving cell to target
Area switching flow process as shown in figure 1, including：
Step 101, judge Serving cell and Target cell whether colocation site shared antenna, or Serving cell coverage is
The no coverage for completely including Target cell；
In the embodiment of the present invention, Serving cell that UE is currently accessed and Target cell adjacent area each other.When RNC is needed at judgement
When whether wireless qualities of certain UE in Serving cell in Target cell meets wireless access condition, adjudicated as follows：
Judge Serving cell and Target cell whether colocation site shared antenna, or whether Serving cell coverage wraps completely
Coverage containing Target cell.Whether whether co-sited shared antenna is the basic of network planning personnel with inclusion relation to multiple cell
Layout data；Whether minizone is also one of network planning data with inclusion relation, is marked typically by network management data.
If it is judged that being yes, step 102 is proceeded to；If it is judged that being no, step 103 is proceeded to.
Step 102, in the covering of the Serving cell and the Target cell colocation site shared antenna or the Serving cell
When scope completely includes the Target cell, wireless quality of the Serving cell in the UE present positions is obtained；
In this step, radio signal quality of the Serving cell in the UE present positions is obtained first.Realizing this
During invention, inventor has found in field of wireless communication that with the increase of frequency values the loss of wireless signal also increases,
The coverage of respective cell can reduce；But under identical wireless environment, the wireless fading channel of the cell of different frequency has one
Fixed corresponding relation, can measure in such as general commercial network, for cobasis station shared antenna identical transmission power U2100 and
U900 cells, the general 8dB higher than U2100 of wireless quality (RSCP) for covering edge U900 cells in U2100 or so.Therefore, it is right
In the cell of the identical transmission power but different frequency of cobasis station shared antenna, the wireless quality of low frequency cell well to a certain extent when
(such as when more than preset wireless quality thresholding), covers the wireless quality and the low frequency cell of the high frequency cell of same position
Relatively, thus the wireless quality of Target cell can be determined by obtaining the wireless quality of Serving cell that be currently accessed.
Specifically, wireless quality of the Serving cell in current location can be obtained by following either type：
Nothing between (Measured results on RACH), frequently interior or frequency is obtained in RACH measurement reported result
(MEASUREMENT REPORT) is obtained in line mass measurement report.
Serving cell is being obtained after the wireless quality of UE positions, step 104 is being proceeded to.
Step 103, in the Serving cell and the Target cell non-co- site shared antenna, and UE Serving cells
When coverage can not completely include the Target cell, abandon to the Target cell switching.
When step 104, the Serving cell wireless quality in the UE present positions reach preset handoff threshold, according to institute
The wireless quality incidence relation of Serving cell and the Target cell is stated, determines the Target cell in the UE present positions
Wireless quality meets wireless access condition；
In the embodiment of the present invention, it is first determined the incidence relation of Serving cell and Target cell wireless quality, then in advance
One handoff threshold is set.The principle for arranging handoff threshold is to ensure that the wireless quality in Serving cell reaches the handoff threshold
When, the wireless quality of Target cell disclosure satisfy that UE be handed over after service needed.
Preferably, the radio quality values that the Target cell covers the corresponding Serving cell of marginal position are set to cut
Change thresholding.
When Serving cell wireless quality in the UE present positions reaches preset handoff threshold, you can determine that target is little
The wireless quality in area meets the needs of UE current business enough, can switch over, into step 105.
If the Serving cell wireless quality not up to preset handoff threshold of the UE present positions, then it is assumed that target
The wireless quality of cell is also not sufficient to ensure that the business of UE, therefore stops the flow process of cell switching.
Step 105, the instruction UE initiate the switching from the Serving cell to the Target cell.

The index of signal quality), and compare with preset handoff threshold (Threshold1 or Threshold2)；If it find that little
The radio signal quality of area A reaches preset handoff threshold (such as RSCP ＞=- 92dBm or Ec/No ＞=- 10dB), then
Think：The wireless coverage quality of UE positions cell B can meet business demand (the RSCP ＞=- 100dBmor Ec/ of UE
No ＞=- 12dB)；
If step 303, RNC need for the UE to be switched to cell B (such as：UE and cell B all support dual carrier HSDPA,
Cell A does not support dual carrier HSDPA；Or cell A load is very high but cell B load is relatively low), then will be RRC connection establishments direct
It build Microcell B in.

Threshold2) compare；If it find that the radio signal quality of cell A higher than preset handoff threshold (such as RSCP ＞=-
92dBm or Ec/No ＞=- 10dB), then it is assumed that：The wireless coverage quality of UE positions cell B it is not poor yet (RSCP ＞=-
100dBm orEc/No ＞=- 12dB)；
Step 505, just whether can need for the UE to be switched to cell with decision-making when RNC receives the RAB assignment requests of CN
B：If necessary to switching (such as：Cell A supports voice-and-data business and load is higher, and cell B is only supported data service and born
