Embodiment two
With reference to Fig. 4, show the flow chart of steps of a kind of cell switching method according to the embodiment of the present application two.
The multicarrier of the present embodiment comprises the following steps with the cell switching method covered under layering networking scene:
Step S302: base station determines that UE initiates to switch from cell-of-origin to Target cell.
In the present embodiment, cell-of-origin and Target cell are multicarrier with the community covered in the communication network of layering networking, and cell-of-origin and Target cell include the same coverage cell of multiple multicarrier.
Step S304: base station obtains the measurements interference ratio of the multiple multicarriers in Target cell with coverage cell respectively.
Introduce " measurements interference ratio " this parameter, use in order to synthetic determination switching target small area in cell switch process, represent with SOI.In the present embodiment, the measurements interference of a community is than referring to the ratio that the RSRP of the adjacent cell (as same in multiple multicarriers in the present embodiment with cell-of-origin adjacent Target cell coverage cell) adjacent with this community measures relative value and is interfered, this value is larger, and to represent the resultant effect of nearby region measurement level and interference level better, such as RSRP signal is very strong, disturbs very little; Otherwise then meaning that the resultant effect of adjacent area is poor, be such as disturb very greatly, or RSRP signal is relatively weak.
In the present embodiment, obtain the measurements interference ratio of each multicarrier in Target cell with coverage cell by formula (1).That is:
SOI=RSRP_R/I formula (1)
Wherein, I is the interference value that adjacent area is subject to, and comprises uplink interference and descending interference, is measured and statistics obtains by eNB; RSRP_R is that adjacent area (the same coverage cell of each multicarrier as in Target cell in the present embodiment) RSRP that UE reports measures the relative value of level (representing with RSRP_N) relative to local area (the same coverage cell of each multicarrier as corresponding in cell-of-origin in the present embodiment) levels of service (representing with RSRP_S), that is:
RSRP_R=RSRP_N-RSRP_S formula (2)
LTE is the mutual EVAC (Evacuation Network Computer Model) in minizone, and during identical networking, interference is main from neighbor cell, as covered layering networking for 2 carrier waves are same, is equal to existence 2 LTE common-frequency networks.Situation is disturbed in order to what obtain Target cell, also be, obtain adjacent area interference value I, the mutual mode of X2 interface can be passed through, by Target cell, interfere information is sended over, that is, the base station of community, current place is by X2 interface, and each multicarrier in the Target cell that the base station obtaining Target cell sends is with the interference value of coverage cell.Though this mode can obtain interference value, need interactive interfacing, time delay is larger, can not react disturbed condition when switching in time.
For this reason, after switching according to the reciprocity of identical networking interference and UE in the present embodiment, former Serving cell will change the actual conditions of interfered cell into, adopting the interferometry information of sector, UE place (the Liang Ge community as covered) to substitute the interference of estimation adjacent cell, meeting the requirement that interfere information obtains promptness.Also namely, use each multicarrier in cell-of-origin with the interference value of coverage cell, as the interference value of each multicarrier corresponding in Target cell with coverage cell.
Still cover layering networking so that 2 carrier waves are same, according to same overlay network structure, the Liang Ge community (community 1 and community 2) of sector, UE place belongs to same base station, assuming that UE switches anteposition in community 1, so adjacent area (as the adjacent area A) disturbed condition obtained on the frequency of place, community 1 can directly be measured and add up in community 1; Adjacent area (as the adjacent area B) interference obtained on the frequency of place, community 2 can directly be measured and add up in community 2, and like this by base station communication, community 1 can obtain adjacent area (as adjacent area A and the B) disturbed condition of place, community 2 frequency.Formula is used to be expressed as: SOI
a=RSRP_R
a/ I
1; SOI
b=RSRP_R
b/ I
2; Wherein, SOI
arepresent the measurements interference ratio of adjacent area A, RSRP_R
arepresent that the RSRP of adjacent area A measures relative value, I
1then represent the interference value of community 1; Equally, SOI
brepresent the measurements interference ratio of adjacent area B, RSRP_R
brepresent that the RSRP of adjacent area B measures relative value, I
2then represent the interference value of community 2.
Step S306: the multiple multicarriers in comparison object community, base station, with the measurements interference ratio of coverage cell, determine that the maximum community of the ratio of wherein measurements interference ratio is target handover cell.
Still for 2 carrier waves with covering layering networking, in switch decision process, compare the SOI value on 2 target frequencies, the large community of selection SOI value, as target handover cell, completes handoff procedure.
But those skilled in the art should understand, in actual use, for the multicarrier more than 2 carrier waves with the situation covering layering networking, what also likely select is not the maximum community of the ratio of measurements interference ratio, but select suitable community according to actual conditions, as when measurements interference than maximum community do not meet other switch decision conditioned disjunction be rejected in target side time, the community etc. that the ratio of measurements interference ratio is time large can be selected.
Step S308: UE switches from cell-of-origin to the target handover cell determined by base station.
By the present embodiment, in cell switch process, consider the disturbed condition of Target cell, be conducive to UE and be directly switch on the relatively little target handover cell of interference, reduced the co-channel interference of system, promote handover success rate.

The multicarrier of the present embodiment comprises the following steps with the cell switching method covered under layering networking scene:
Step S402:UE reports handover measurement to report, wherein with 2 adjacent area RSRP measured values and the RSRP level of same covering.
Step S404: base station is compared the adjacent area RSRP level reported and whether met switching condition, if do not meet, does not then carry out hand-off process; If meet, then carry out step S406.
If adjacent area RSRP level meets switching condition, then base station can determine that UE initiates to switch from cell-of-origin to Target cell.
Step S406: the Target cell judgement of base station triggers handoff procedure.
Step S408: whether the frequency priority that adjacent area is compared in base station is identical, if different, then carries out step S410; If identical, then carry out step S412.
Step S410: hand-off process is carried out as target handover cell in the community that base station selected frequency priority is the highest, terminates this switching flow.
Step S412: the size of the measurements interference ratio of calculating adjacent area, base station, and comparative sorting.
Wherein, the calculating of measurements interference ratio can adopt the mode in previous embodiment, at this not in detailed description.
Step S414: hand-off process is carried out as target handover cell in the maximum community of base station selected measurements interference ratio.
Pass through the present embodiment, judge on basis at employing adjacent area RSRP, judgement and the switching of target handover cell is carried out with reference to adjacent area interference, consider adjacent area RSRP measured value and frequency disturbed condition to select to judge switching target small area, UE can be switched on the relatively little community, frequency place of interference.
