Business and the big data business of all users that low domestic consumer initiates；
Single-frequency point cell layer E：Capacity is small, and wireless frequency value is low, is mainly used to carry the general of VIP user
Logical business.
Understand that cell layer B is identical with cell layer C network carrying characteristic based on above-mentioned small area carrier strategy,
Cell layer A, cell layer B/C, cell layer D, cell layer E network carrying characteristic it is different.Such as
Shown in Fig. 3, cell layer B is identical with cell layer C network carrying characteristic, and the gravity treatment factor of cell is set
To be identical, for example, all it is 2；Cell layer A, cell layer B/C, cell layer D, cell layer E network are held
Load characteristic is different, and the gravity treatment factor is set to different.Therefore, the gravity treatment factor example of each cell layer
Such as set as follows：
Cell layer A cell：The gravity treatment factor=1；
Cell layer B cell：The gravity treatment factor=2；
Cell layer C cell：The gravity treatment factor=2；
Cell layer D cell：The gravity treatment factor=3；
Cell layer E cell：The gravity treatment factor=4.
Fig. 4 is the flow chart of the embodiment of the present invention one.As shown in figure 4, the cell choosing that the present embodiment is provided
Selection method, comprises the following steps：
Step 401：The network carrying characteristic and the carrying strategy of operator that eNodeB considers as needed are needed
The gravity treatment factor that cell is set is sought, wherein, the gravity treatment factor of the cell with identical network bearer properties is set
It is set to identical；The gravity treatment factor of cell with heterogeneous networks bearer properties is set to difference.
Network environment and desired carriers carry strategy based on the operator shown in Fig. 3 are it is assumed that have five
Layer cell, wherein, cell layer B is identical with cell layer C network carrying characteristic, cell layer A, cell
Layer B/C, cell layer D, cell layer E network carrying characteristic it is different, therefore, each cell layer
The gravity treatment factor sets as follows：

Step 402：ENodeB be broadcast to by being broadcast the message the gravity treatment factor of broadcast cell and adjacent area
UE。
Step 403：ENodeB sets the UE gravity treatment factor；
Specifically, eNodeB consider UE User Priority, UE abilities, UE covering grades,
The factors such as cell load, determine that UE tends to be carried on some carrier wave, then the gravity treatment factor of the UE is set
It is set to the gravity treatment factor of the corresponding cell of the carrier wave.
Step 404：The UE gravity treatment factor is sent to UE by eNodeB by dedicated signaling, wherein, hair
The dedicated signaling for sending the gravity treatment factor can be beep-page message (Paging message), RRC connection release message,
The downlink dedicated message such as RRC connection refused messages.
Step 405：UE matches to carry out cell weight according to the gravity treatment factor of oneself with the gravity treatment factor of cell
Choosing；Specifically, UE matches the gravity treatment factor of the gravity treatment factor of oneself and cell, prioritizing selection weight
The factor and UE gravity treatment factor identical cell is selected to select the Target cell with gravity treatment as cell；If not yet
There are the gravity treatment factor and UE gravity treatment factor identical cell, then select network carrying characteristic and this terminal
The cell that network carrying characteristic is most matched selects the Target cell with gravity treatment as cell.

Example based on Fig. 3, because the general service of VIP user is carried on cell layer E, so silent
The gravity treatment factor recognized is 4.
Step 501：When being downloaded to VIP user's pushing software and send beep-page message, due under software
The big data business such as load are carried on cell layer D, and the cell layer D gravity treatment factor is 3, therefore, by UE
The gravity treatment factor be set to 3；
Step 502：ENodeB carries the " information of the gravity treatment factor=3 " in beep-page message；
Step 503：UE receives carrying and " after the beep-page message of the gravity treatment factor=3 ", finds and oneself is current
Paging factor value it is different, triggering cell gravity treatment, in gravity treatment to cell layer D；
Step 504：UE sets up the big data biography that RRC is connected and carried out software download on cell layer D
It is defeated；
Step 505：After the completion of UE data transfers, eNodeB carries " weight by RRC connection release message
The information of the factor=4 " is selected, so that the VIP user resides at carrying VIP general servicies in idle pulley
On cell layer E；
Step 506：UE receive carrying " after the RRC connection release message of the gravity treatment factor=4 ", according to
The new gravity treatment factor carries out cell reselection, is resident on cell layer E.
Fig. 6 is the flow chart of the embodiment of the present invention three.As shown in fig. 6, present embodiments providing based on weight
Select the cell reselection rules of the factor and the example of other cell reselection rules.In this, cell layer refer to gravity treatment because
Sub- identical candidate set.
Step 601：UE judges whether current area layer is not present the cell for meeting resident condition；
If there is the cell for meeting resident condition, step 602 in current area layer：UE is judged whether
The closer cell layer of the gravity treatment factor of the gravity treatment factor and UE；
It is small in all candidates if there is the closer cell layer of the gravity treatment factor of the gravity treatment factor and UE
Cell reselection, and the closer cell of the gravity treatment factor of the prioritizing selection gravity treatment factor and UE are carried out in region layer
Layer in can persistent district as gravity treatment Target cell；
If the cell for meeting resident condition is not present in current area layer, enter in all candidate cell layers
Row cell reselection, and the prioritizing selection gravity treatment factor and staying in the closer cell layer of the UE gravity treatment factors
Cell is stayed as the Target cell of gravity treatment；
If there is the cell for meeting resident condition in current area layer, and in the absence of the gravity treatment factor and UE gravity treatments
The closer cell layer of the factor, then carried out in currently resident cell layer based on wireless quality sequence, frequency
The cell reselection of the rules such as point priority ranking.
In addition, the embodiment of the present invention also provides a kind of cell selecting apparatus, applied to terminal, including：Extensively
