Step 12, the most cell of antenna amount is retained in the list of target handover cell, and updates target handover cell
List.
In one embodiment of the invention, the most cell of antenna amount at least one.Which base station is known that
Antenna in cell quantity is most, also, each producer can be there are many different implementations.
In one embodiment of the invention, updated target handover cell list is original target handover cell list
Subset.
In one embodiment of the invention, in target handover cell list in the updated only comprising antenna amount most
More target handover cells.For example, based in the target handover cell list generated under existing switchover policy comprising 6 small
Area, wherein 2 antenna cells have 3,4 antenna cells have 1, and 8 antenna cells have 2；So, retain most small of antenna amount
Area, updated target handover cell list only have the cell of 28 antennas.
Step 13, by original switchover policy, a cell is selected to execute in target handover cell list in the updated
Switching.
It is subsequent completely in accordance with original switching plan since updated target handover cell list is the subset of original list
Cell is slightly chosen to switch over.According to original switchover policy, it is bound to select a Target cell.
The present invention proposes that one kind preferentially judges target handover cell antenna amount for the multiaerial system in LTE network
Optimized switching method, give full play to network capabilities, maximization network performance promotes user's perception.
Below in conjunction with the drawings and specific embodiments, method flow of the invention is described further.Art technology
Personnel are to be understood that embodiment here is only intended to illustrate, and should not be construed as limiting the invention.
Fig. 2 show the flow diagram of one of another embodiment of the present invention optimized switching method.This method includes

List update unit retains the most cell of antenna amount in the list of target handover cell, and more fresh target is cut
Changing district list.Wherein, the most cell of antenna amount at least one.
Switch unit selects a cell to hold by original switchover policy in target handover cell list in the updated
Row switching.In one embodiment, updated target handover cell list is the subset of original target handover cell list.?
In one embodiment, updated target handover cell list only includes the most target handover cell of antenna amount.
As shown in figure 4, terminal includes measuring unit and feedback unit.Wherein:
Measuring unit measures neighboring community's reference signal strength, i.e. RSRP, unit dBm.
Neighboring community's reference signal strength is sent to base station by feedback unit.
Wherein, RSRP is the linear averaging power for seeking the cell special reference carried in measurement frequency bandwidth.RSRP
It is the key parameter that wireless signal strength can be represented in LTE network.
