In order to enable those skilled in the art to be more clearly understood that technical solution provided in an embodiment of the present invention, lead to below
Specific embodiment two is crossed, a kind of switching method provided in an embodiment of the present invention is described in detail.In embodiment two, it is
Facilitate explanation, as illustrated in fig. 2, it is assumed that in heterogeneous network, the number of macro base station is 2, respectively macro base station A and macro base station B,
Macro base station A is the base station belonging to macrocell A, and macro base station A may also have other macrocells in addition to macrocell A, macrocell A to cover
It is the base station that Microcell C belongs to have micro-base station C, micro-base station C under lid range, and UE is to access the user equipment of macrocell A, and UE is simultaneously
Under coverage area in Microcell C and macrocell A.As shown in figure 3, this method includes：
301, macro base station obtains the speed parameter of the UE of access macrocell.
Illustratively, which can obtain according to the number for the cell that UE switched in the given time.
Macro base station A can obtain the historical record (UE History Information) of UE, and the speed to obtain UE is joined
Number.Wherein, which may include the cell information that UE switched, and be included in residence time and the cell of each cell
Type.Wherein, cell type includes verysmall (very small), small (small), medium (medium), large (big), here
The cell that type is very small and small can be determined as Microcell, type is true for the cell of medium and large
It is set to macrocell.
Specifically, the historical record of above-mentioned acquisition UE can include but is not limited to following acquisition modes：
(1), the macro base station A where UE receives the historical record that the upper serving BS that UE switches is sent, at this
In embodiment, if UE is switched to macro base station A from macro base station B, macro base station A can receive the historical record that macro base station B is sent.
(2), the macro base station A where UE receives the historical record that UE is sent.
According to the historical record of UE, the detailed process for obtaining the speed parameter of UE may include：
Specifically, macro base station A can be using macrocell number that UE in the predetermined time switched as switching in the predetermined time
The cell number crossed, i.e., will be including the Microcell statistics of UE switchings.Alternatively,
Macro base station A can obtain the number for the macrocell that UE switched in the predetermined time and the number of Microcell, and will be micro-
It after the number of cell is multiplied by coefficient, is added with the number of macrocell, generates the cell number that UE switched in the predetermined time, and will
The cell number is as speed parameter.Illustratively, following formula can be utilized：
Macrocell number+pre- the timings of coefficient * for the cell number switched in predetermined time=switched in the predetermined time
The interior Microcell number switched.Further according to the cell number acquisition speed parameter switched in the predetermined time, wherein this is
Number is less than 1, it is preferred that the coefficient can take 0.5.
Other than aforesaid way, macro base station A can also utilize other manner to obtain the speed parameter of UE, not limited herein
It is fixed.
302, macro base station judges the numerical relation of the speed parameter and first threshold and second threshold of UE, determines that control UE exists
Whether the switching in macro small section is carried out in heterogeneous network.
Optionally, if the speed parameter of UE be more than second threshold, judge UE for high speed, it is corresponding execute 303；If UE's
Speed parameter is more than first threshold, is less than or equal to second threshold, judgement UE is middling speed, corresponding to execute 304；If the speed of UE
It spends parameter and is less than or equal to first threshold, then judge that UE for low speed, accordingly executes 305.
Specifically, judging that the numerical relation whether speed parameter of UE is more than first threshold can be specifically：
The cell number switched in predetermined time is more than second threshold, determines that UE is high speed；
The cell number switched in predetermined time is more than first threshold, and is less than or equal to second threshold, determines that UE is
Middling speed；
The cell number switched in predetermined time is less than or equal to first threshold, determines that UE is low speed.
In addition, macro base station can also be by judging the speed parameter of UE and the numerical relation of first threshold, UE is different for control
Whether the switching in macro small section is carried out in network forming network.
If 303, judging UE for high speed, macro base station controls switchings of the UE in heterogeneous network without macro small section, knot
Beam.
Illustratively, it since before cell switches, user equipment measures multiple Microcells, obtains and meets switching
The Microcell of condition generates measurement report, which can be the threshold value of the mobility parameters of base station, so, small
When area switches, macro base station A can be able to be TTT (Time To by adjusting the mobility parameters of itself, the mobility parameters
Trigger, time of measuring), A3 thresholdings (A3threshold, A3 event thresholds value) and eICIC (enhanced Inter Cell
Interference Coordinator, the Inter-Cell Interference Coordination of enhancing) parameter, such as CRE (Cell Range
Extension, cell range extension) so that Microcell is unsatisfactory for switching condition, and only includes satisfaction in the measurement report of UE and cut
The Microcell for changing condition cannot trigger switching flow due to not meeting the Microcell of switching condition in the measurement report of UE, from
And make the UE that can not be switched to Microcell from macrocell.
If 304, judging UE for middling speed, macro base station controls switchings of the UE in heterogeneous network without macro small section, and
The first Protection parameters are adjusted, are terminated.
Specifically, due to when UE is under the coverage area of Microcell, but is serviced by macro base station, Microcell can cause UE
Larger interference, so, macro base station A is except through adjusting the mobility parameters of itself, to control user equipment in heterogeneous network
In network without the switching in macro small section except, in order to protect middling speed UE not interfered by Microcell, reduce link down
Rate, macro base station also need to the micro-base station belonging to notice Microcell and the first Protection parameters are arranged, i.e. macro base station notifies micro-base station UE tune
The subframe position of degree, instruction Microcell does not dispatch these subframes, to reduce interference of the Microcell to middling speed UE.Specifically,
First Protection parameters can be blank frame position, the blank frame position may be used ABS (Almost BlankSubframe,
Empty frame) technology determination, by leaving a blank in advance in the up channel of Microcell or down channel or uplink and down channel
White frame ensures communication quality to reduce interference of the Microcell to the UE.
It is worth noting that, 303 steps and 304 steps are all to control user equipment in heterogeneous network without macro small
The switching in section, in addition to above-mentioned macro base station is by adjusting the mobility parameters of itself, control user equipment is in heterogeneous network
Without the switching in macro small section, following methods can also be used to control user equipment in heterogeneous network without macro small
The switching in section：
Macro base station A issues Microcell list to UE, and instruction UE does not measure the Microcell in the list of Microcell, to touch
It is dealt into the switching flow of these Microcells, switching of the control user equipment in heterogeneous network without macro small section.Or
If including Microcell in when the UE measurement reports that macro base station A is received, macro base station A ignores the Microcell in measurement report, selects
Macrocell is selected as Target cell, if there was only Microcell in measurement report, without switching, is existed to control user equipment
Switching in heterogeneous network without macro small section.Macro base station A can also utilize other manner to control user equipment in isomery
Switching in network without macro small section, is not limited herein.
Due in macro and micro networks, when move UE with middling speed by Microcell when, if UE is switched to Microcell, because
For middling speed UE in Microcell the residence time it is short, higher soldier pang rate (Ping-Pong Rate, PPR), radio chains can be caused
Road mortality (Radio Link Failure, RLF) and handover failure (Handover Failure, HOF).So the present invention is real
It applies example and uses the switchover policy that the UE of middling speed is not switched to Microcell, and pass through the up channel or downlink in Microcell
Reserve blank frame in channel or uplink and down channel, reduce interference of the Microcell to UE, to ensure UE and network it
Between communication quality.
If 305, judging UE for low speed, macro base station selection target Microcell, and control UE from macrocell to be switched to target micro-
Cell adjusts the second Protection parameters, terminates.
Specifically, macro base station is configured to the handoff parameter of Microcell for low speed UE, it is preferred that A3=2dB can be configured,
TTT=320ms so that UE can report qualified Microcell, when macro base station A receives the measurement report of UE transmissions,
Macro base station A determines that target is small according to the signal parameter of at least one Microcell in measurement report from least one Microcell
Area, and UE is switched into the target Microcell.Illustratively, which can be RSRP (Reference Signal
Received Power, Reference Signal Received Power).Macro base station A can select the highest Microcells RSRP for target Microcell.
Include only macrocell if not including Microcell in the measurement report that UE is reported, then macro base station selects suitable macrocell to carry out
Switching.
In order to ensure to reduce the interference of Microcell after UE is switched to target Microcell from macrocell, macro base station A can be with
The second Protection parameters of itself are adjusted, which can be blank frame position, and send message informing Microcell, refer to
Show that blank frame position of the Microcell by UE scheduling in macro base station after UE is switched to Microcell can specifically prepare in switching
It asks to send the information in (Handover Request).
Due to movement UE with low speed by Microcell when, if not cutting Microcell, can because of UE covering in Microcell
The lid range lower time is too long, and causes the communication between Microcell interference UE and macro base station, leads to UE signal interruptions, so using
The embodiment of the present invention takes the switchover policy that UE is switched to the preferable Microcell of signal quality from macrocell so that UE passes through micro-
Cell is communicated with network side, to ensure the communication quality between UE and network.
The embodiment of the present invention provides a kind of switching method, and the speed parameter of the UE of macro base station is accessed by acquisition；Secondly root
According to the numerical relation between the speed parameter and First Speed threshold value of UE, the switchover policy of UE is determined；It is finally based on determining cut
Strategy is changed, UE is switched into target Microcell from macrocell, for the UE of friction speed parameter, takes different switchover policy,
The UE that movement velocity is low speed is switched into Microcell from macrocell, not by UE that speed parameter is middling speed or high speed from macro small
Area switches to Microcell, and the interference to UE is reduced by the way of Protection parameters are arranged, to increase UE with it is internetwork
Communication quality improves the communication performance of network.
