Embodiment
For making the purpose, technical solutions and advantages of the present invention express clearlyer, the present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
In embodiments of the present invention, UE uses at least two sectorized antennas, and the reception signal of different sectorized antennas is measured respectively; If it is same BBU that the reception signal of the different sectorized antennas of UE belongs to same residential quarter, according to selecting a measurement result to report to the base station together with residential quarter ID at least two measurement results; If it is different BBU that the reception signal of the different sectorized antennas of UE belongs to different residential quarters, UE reports to the base station together with measurement result and the corresponding residential quarter ID of at least two residential quarters.The measurement result of at least two residential quarters that UE reports is received in the base station, determines by the base station whether this UE carries out the residential quarter and switch, if reach corresponding condition, notifies this UE to carry out the residential quarter and switches.
UE utilizes at least two sectorized antennas that the signal that receives is separately measured respectively, to obtain the signal measurement result of different directions, has increased selectivity and the accuracy of UE to different directions uplink link; Increased simultaneously the measurement number of times to neighbor cell, UE can complete Cell searching within the relatively long time, and then has increased the success rate of switching, and then has reduced the cutting off rate of UE conversation.
Need to prove: for the private network communication system of high-speed railway, UE can be the onboard system on train, and its sectorized antennas is the antenna that train exterior is installed.
Are method flow schematic diagrames of cell measurement and switching referring to accompanying drawing 2, specifically comprise the following steps:
In the present invention, UE uses at least two sectorized antennas, and the reception signal of different sectorized antennas is measured respectively.Because sectorized antennas has certain directivity, UE uses sectorized antennas only to measure the reception signal of certain direction.
It is same residential quarter that the reception signal of different sectorized antennas belongs to same BBU, the measurement result residential quarter ID corresponding with it in the measurement result in the measurement result of different sectorized antennas is reported to the base station.
When the reception signal of the different sectorized antennas of UE belongs to same residential quarter, get the sectorized antennas of maximum, transmitting uplink data or the sectorized antennas principle that downlink data receives according to different sectorized antennas, select a measurement result to report to the base station together with residential quarter ID at least two measurement results.
Different sectorized antennas are got maximum: the measurement result at least two sectorized antennas of UE compares, and gets wherein maximum measurement result and corresponding residential quarter ID reports together.
The sectorized antennas of transmitting uplink data: if the transmitting uplink data of UE is carried out a day line options, be also that UE is when uplink, select the some antennas at least two sectorized antennas to carry out the transmission of upstream data, the down-run survey result and the corresponding residential quarter ID that choose the antenna that carries out transmitting uplink data report together.
The sectorized antennas that downlink data receives: if UE carries out a day line options when downlink data receiving, be also that UE is when carrying out the downlink data reception ﹠ disposal, only select the downlink data of the some antennas at least two sectorized antennas to process, the down-run survey result and the corresponding residential quarter ID that choose the antenna that carries out downlink data transmission report together.
Referring to accompanying drawing 3, UE carries out respectively the reception of downlink data by sectorized antennas 1 and sectorized antennas 2.Two sectorized antennas receive respectively the signal of different directions, UE measures respectively, in two measurement results, get according to different sectorized antennas the sectorized antennas principle that the sectorized antennas of maximum, transmitting uplink data or downlink data receive and select a measurement result, with this measurement result together with residential quarter ID reporting base station.Because RRU0, RRU1, RRU2 and the RRU3 at UE place all belongs to same BBU, also namely belong to same residential quarter, so the measurement result of the different sectorized antennas of UE belongs to same residential quarter.The measurement result that the base station reports according to UE is carried out the adjustment of modulation coding mode (MCS) and credit rating indication (CQI).
It is different residential quarters that the reception signal of different sectorized antennas belongs to different BBU, the measurement result of different sectorized antennas is carried out following processing.
When the reception signal of the different sectorized antennas of UE belongs to different residential quarters, measurement result that will at least two residential quarters and the residential quarter ID of correspondence report to the base station together.Referring to accompanying drawing 4, UE carries out respectively the reception of downlink data by sectorized antennas 1 and sectorized antennas 2.Two sectorized antennas receive respectively the signal of different directions, and UE measures respectively, in two measurement results, with different measurement results together with corresponding residential quarter ID reporting base station together.RRU2, the RRU3 at UE place belong to BBU1, and the described RRU0 of UE and RRU1 belong to BBU2, so the measurement result of the different sectorized antennas of UE belongs to different residential quarters.
Wherein, also can utilize step 201 to 203 technical scheme to carry out cell measurement.
The measurement result that step 204, base station report according to UE determines whether UE switches.
The measurement result that the base station reports according to UE determines whether UE switches.Concrete, according to the measuring-signal of neighbor cell whether greater than the signal of certain threshold value, neighbor cell whether, measuring-signal this residential quarter better than the signal quality of this residential quarter whether be worse than the criterions such as certain threshold value, determine whether this UE carries out the residential quarter and switch.If reach corresponding condition, notify this UE to carry out the residential quarter and switch.Above-mentioned whether the switching according to criterion decision UE is prior art.
Because UE adopts sectorized antennas, the signal of different directions is measured respectively, cell measurement results is reported to the base station, determine the residential quarter switching by the base station.Adopt such scheme, increased the accuracy of measuring, extended the time that UE switches, increased the success rate that UE switches when further having lowered the conversation cutting off rate.
Are system configuration schematic diagrames of cell measurement and switching referring to accompanying drawing 5, comprise:
This system comprises device and the base station of cell measurement and switching.Wherein, the device of cell measurement and switching comprises: sectorized antennas 501, control module 502 and handover module 503.
Measuring unit 5021 is used for the signal of different sectorized antennas is measured, and measurement result is sent to corresponding cell ID reports unit 5022.
The above is only preferred embodiment of the present invention, is not for limiting protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
