Embodiment
In LTE, UE can continue the radio link quality of Serving cell to monitor, and with the Serving cell channel quality degrades of finding to cause due to channel sudden change or mobility, specifically comprises the steps:
When UE receives continuous N310 " step-out indication ", start timer T310;
If at T310 timer run duration, UE receives continuous N311 " synchronously indication ", and UE stops T310 timer, continues the channel quality of Monitoring Service community;
If T310 timer expiry, there is Radio Link Failure in Serving cell, and UE carries out cell reselection process, starts T311 timer simultaneously.
" step-out indication " refers to that the Signal to Interference plus Noise Ratio (SINR) of Serving cell is lower than the first threshold value Qout, and the SINR that " synchronously indication " refers to Serving cell is higher than the second threshold value Qin.Wireless link monitoring and Radio Link Failure process schematic diagram are as shown in Figure 1, this mechanism can be interpreted as intuitively: the channel quality of UE Monitoring Service community, when after the channel quality variation of Serving cell, first attempt recovering and being connected of Serving cell, in the regular hour (T310) if in Serving cell channel quality improve, UE recovery is connected with Serving cell, if all do not recovered before T310 is overtime and being connected of Serving cell always, UE selects the better community of other channel qualities to access so.The effect of Radio Link Failure (RLF) mechanism is the variations of Monitoring Service community, and supports channel quality to recover, to avoid unnecessary cell reselection and connection reconstruction process.
Wireless link monitoring in LTE and the switching of Radio Link Failure process in HetNet, there is negative effect, specifically as shown in Figure 2.The current Serving cell of UE is Pico community, and UE moves to Macro community from Pico community along the direction of arrow in the figure.Along with the movement of UE, the channel quality of Pico community variation gradually, in the time moving to A point, UE has received N310 " step-out indication " continuously, now starts T310 timer.Due to the limited coverage area of Pico community, in T310 timer expiry, UE has shifted out the coverage of Pico community, cannot recover and being connected of Pico community, and it is unnecessary that this connection re-establishes process.Therefore, existing RLF mechanism is no longer applicable to heterogeneous network, need to be optimized for the feature of heterogeneous network.
The application is for the feature of above-mentioned heterogeneous network, in the method that wireless link is monitored providing, UE can be according to the difference of environment of living in, adopts the RLF parameter of different value sizes, reduce the time that transfer of data is interrupted, with the demand that adapts to switch under different scenes.If switch more urgently, UE can start RLF recovery process earlier, thereby captures earlier the decline of Serving cell channel quality.Correspondingly, UE can be earlier connects with the adjacent cell of the good Serving cell of channel quality.
The application's basic fundamental design be UE according to the difference of handoff scenario, adjust adaptively the size of RLF process relevant parameter.Self adaptation is adjusted RLF process relevant parameter based on cell type.RLF process relevant parameter comprises T310, N310, Qout and Qin.
For making know-why, feature and the technique effect of present techniques scheme clearer, below in conjunction with specific embodiment, present techniques scheme is described in detail.
Embodiment mono-: the type based on Serving cell is adjusted RLF parameter
In heterogeneous network, dissimilar community has different coverages, and the urgency level that UE switches between dissimilar community is different.For example, the urgency of the switching between Pico-Macro is far longer than between Macro-Macro to be switched, reason is that the transmitting power of Pico community is less, when UE is during away from Pico community, the channel quality of Pico community can promptly decline, if UE cannot connect with Macro community as soon as possible, be easy to cause and the disconnecting of Pico community, cause handoff failure.
According to the size of coverage, cell type can be divided into two classes: first kind community and Equations of The Second Kind community, wherein the transmitting power of Equations of The Second Kind community and coverage are greater than first kind community.Equations of The Second Kind community is macro base station community normally, and first kind community is generally LPN community.UE, according to the difference of Serving cell type, adopts Qout and the N310 parameter of different values.
The method flow that wireless link is monitored that the embodiment of the present application one provides as shown in Figure 1, the method that the radio link quality of this flow process based on aforementioned Serving cell monitored, when UE receives continuous N310 " step-out indication ", start timer T310; If at T310 timer run duration, UE receives continuous N311 " synchronously indication ", and UE stops T310 timer, continues the channel quality of Monitoring Service community; If T310 timer expiry, there is Radio Link Failure in Serving cell, and UE carries out cell reselection process, starts T311 timer simultaneously; Step-out indicates the Signal to Interference plus Noise Ratio SINR that refers to Serving cell lower than the first threshold value Qout, and the SINR that " synchronously indication " refers to Serving cell is higher than the second threshold value Qin.The flow process that embodiment mono-provides comprises the steps:
Step 301:UE obtains the cell type of the Serving cell at this UE place;
Step 302: if the cell type of described Serving cell is first kind community, described N310 is set to N310_1, and described Qout is set to Qout_1; If the cell type of described Serving cell is Equations of The Second Kind community, described N310 is set to N310_2, and described the first threshold value Qout is set to Qout_2; Wherein, the transmitting power of Equations of The Second Kind community and coverage are greater than first kind community, N310_1<N310_2, Qout_1>Qout_2.
Described N310 is set to N310_1, described Qout is set to Qout_1: Serving cell utilizes RRC dedicated signaling to monitor relevant parameter { N310_1 for UE configures 2 groups of wireless links, Qout_1} and { N310_2, Qout_2}, UE adopts { N310_1, Qout_1}, described N310 is set to N310_1, and described Qout is set to Qout_1;
Described N310 is set to N310_2, described the first threshold value Qout is set to Qout: Serving cell utilizes RRC dedicated signaling to monitor relevant parameter { N310_1 for UE configures 2 groups of wireless links, Qout_1} and { N310_2, Qout_2}, UE adopts { N310_2, Qout_2}, described N310 is set to N310_2, and described Qout is set to Qout_2.
Utilize this self adaptation to adjust the method for RLF parameter, UE can control the Startup time of wireless link recovery,, in the time that Serving cell is first kind community, starts earlier wireless link recovery process, in the time that Serving cell is Equations of The Second Kind community, start wireless link recovery process more lately.
UE obtains the cell type of the Serving cell at this UE place can be in the following way: base station in service sector sends system message or the dedicated radio resources control RRC signaling of the cell type that carries this community to UE, and UE obtains the cell type of Serving cell from the system message that receives or special RRC signaling.Or base station broadcast carries the system message of the cell type of self; UE receives the system message of Serving cell, obtains the cell type of Serving cell from described system message.
Embodiment bis-: the type of the adjacent cell based on Serving cell and Serving cell is adjusted RLF parameter
Except the type of Serving cell, the type of the adjacent cell of Serving cell (Target cell of switching) also can have influence on the urgency level of switching, for example Macro-Pico, and Pico-Macro, Macro-Macro, Pico-Pico switches corresponding different respectively demands.Therefore, UE, according to the difference of the adjacent cell type of Serving cell and Serving cell, can adopt Qout and the N310 parameter of different values.
Embodiment bis-further optimizes than embodiment mono-, and cost also ratio method 1 is large, because the parameter combinations number that can select for UE is 4 groups, and in embodiment mono-, only has 2 groups.Particularly, when the Serving cell of UE is first kind community, when the adjacent cell of Serving cell is Equations of The Second Kind community, UE adopts parameter { N310_1, Qout_1}; When the Serving cell of UE is first kind community, when the adjacent cell of Serving cell is also first kind community, UE adopts parameter { N310_2, Qout_2}; When the Serving cell of UE is Equations of The Second Kind community, when the adjacent cell of Serving cell is first kind community, UE adopts parameter { N310_3, Qout_3}; When the Serving cell of UE is Equations of The Second Kind community, when the adjacent cell of Serving cell is also Equations of The Second Kind community, UE adopts parameter { N310_4, Qout_4}.The relativeness of parameter value is as follows: N310_1<N310_2<N310_3LEssT.LTss T.LTN310_4, Qout_1>Qout_2>Qout_3GreatT.G reaT.GTQout_4.
Except the different RLF parameter value of direct configuration, another kind of implementation is that network is the zoom factor of the many groups of UE configuration RLF parameter, UE carries out computing according to residing environmental selection one group of zoom factor wherein to the RLF parameter of benchmark, obtains the RLF parameter of current employing.For example,, if benchmark RLF parameter is that { zoom factor is that { the final RLF parameter adopting of UE is { N310*N310_coefficient, Qout*Qout_coefficient} so for N310_coefficient, Qout_coefficient} for N310, Qout}.Specific to the application's method, for embodiment mono-, network is that UE configures 2 groups of RLF parameter zoom factors, in the time that UE Serving cell is first kind community, UE adopts RLF parameter zoom factor 1 to carry out convergent-divergent to RLF parameter, in the time that Serving cell is Equations of The Second Kind community, UE adopts RLF parameter zoom factor 2 to carry out convergent-divergent to RLF parameter.In embodiment mono-, the relativeness of RLF parameter zoom factor value is as follows: N310_coefficient1<N310_coefficient2, Qout_coefficient1>Qout_coefficient2.For embodiment bis-, network is that UE configures 4 groups of RLF parameter zoom factors, and when the adjacent cell that is first kind community, Serving cell when Serving cell is Equations of The Second Kind community, UE adopts RLF parameter zoom factor 1 to carry out convergent-divergent to RLF parameter; When the adjacent cell that is first kind community, Serving cell when Serving cell is also first kind community, UE adopts RLF parameter zoom factor 2 to carry out convergent-divergent to RLF parameter; When the adjacent cell that is Equations of The Second Kind community, Serving cell when Serving cell is first kind community, UE adopts RLF parameter zoom factor 3 to carry out convergent-divergent to RLF parameter; When the adjacent cell that is Equations of The Second Kind community, Serving cell when Serving cell is Equations of The Second Kind community, UE adopts RLF parameter zoom factor 4 to carry out convergent-divergent to RLF parameter.In embodiment bis-, the relativeness of RLF parameter zoom factor value is as follows: N310_coefficient1<N310_coefficient2LEssT.LT ssT.LTN310_coefficient3<N310_coefficient4, Qout_coefficient1>Qout_coefficient2GreatT.
