Background technology
As the type of data service application is more and more extensive, user is traditional to the growing of data-rate requirements
The network architecture based on honeycomb covering can not fully meet new business property requirements, be mainly reflected in two aspects：（1）Pass
System cellular network is poor to indoor covering；（2）Capacity of the conventional cellular network in traffic hotspots area far can not meet need
Ask.
The reason for conventional cellular network is poor to in-door covering is that indoor penetration loss is larger, along with channel radio of future generation
The working frequency of letter system is higher, therefore the user of interior is difficult to obtain high-throughput.In addition, statistics shows, in future
Communication network in, the portfolio of 80%-90% will occur in indoor and traffic hotspots area.Therefore, legacy cellular " weight is outdoor,
Light interior ", the thought of " weight beehive net, light traffic hotspots " can not meet demand.Based on this, third generation affiliate counts
Draw（3GPP）Heterogeneous network is carried out（HetNet, Heterogeneous Network）Research, it is intended to improve gulping down for hot zones
The amount of telling, improves in-door covering.
So-called heterogeneous network, refers to overlap to deploy low power website in the coverage of macro base station, is covered for improving
Lid or lifting handling capacity.These network nodes often have different size of transmission power, different back haul link types.Typical case
Heterogeneous network node include：Macro base station（Macro）, micro-base station（Pico）, Home eNodeB（Femto）And relay base station
（Relay）.Wherein, macro base station cell is used to provide the covering of wide area；Micro-base station cell is used to improve the appearance in hot spot service area
Amount, alleviates the load pressure of macro base station cell；Home base station cells are used to provide more preferable service quality for domestic consumer；Relaying
Base station cell is used to extend the covering of macro base station cell edge, is typically deployed at and is inconvenient to the place for disposing wired backhaul.
Micro-base station, Home eNodeB and relay base station are referred to as low power nodes below（LPN, Low Power Node）.
Heterogeneous network changes the topological structure of conventional cellular network, is deployed simultaneously in system various with different transmitting work(
The website of rate and coverage so that network design is more flexible.But, it is new that heterogeneous network also brings some to system design
Challenge, a series of problems that new network structure is brought is required for solving, and is mainly manifested in the following aspects：
1st, in the case of macro base station cell and LPN cell identical networkings, interference problem can become very serious；
2nd, compared with homogenous networks, the performance of handoffs in heterogeneous network is remarkably decreased.
In order to improve the performance of handoffs in heterogeneous network, 3GPP has passed through special project verification isomery network mobility enhancing（“SI:
HetNet mobility enhancements”）, it is intended to the problem of mobile management presence in heterogeneous network is studied, and phase is provided
The solution answered.Simulation result in research shows, in heterogeneous network LPN cells to macro base station cell handover failure rate highest,
The reason for causing this phenomenon is that the coverage of LPN cells is smaller, and the terminal below LPN cells is easy for out of LPN
The coverage of cell, but but have little time to be switched to macro base station cell, cause handoff failure.

Specific embodiment
In LTE, the radio link quality that UE can be persistently to Serving cell is monitored, with find due to channel mutation or
Serving cell channel deterioration caused by mobility, specifically includes following steps：
When UE receives continuous N310 " step-out instruction ", start timer T310；
If during T310 timers run, UE is received continuous N311 " synchronizing indication ", and UE stops T310 regularly
Device, continues to monitor the channel quality of Serving cell；
If T310 timer expiries, there is Radio Link Failure in Serving cell, UE performs cell reselection process, while opening
Dynamic T311 timers.
" step-out instruction " refers to the Signal to Interference plus Noise Ratio of Serving cell（SINR）Less than the first threshold value Qout, " synchronizing indication " is
The SINR for referring to Serving cell is higher than the second threshold value Qin.Radio Link is monitored and Radio Link Failure process schematic such as Fig. 1 institutes
Show, the mechanism can intuitively be interpreted as：UE monitors the channel quality of Serving cell, when the channel quality of Serving cell is deteriorated
Afterwards, first attempt to recover the connection with Serving cell, in the regular hour（T310）If interior serving cell channel quality improves,
UE recovers the connection with Serving cell, if all not recovering the connection with Serving cell always before T310 time-out, then
UE selects the more preferable cell of other channel qualities to be accessed.Radio Link Failure（RLF）The effect of mechanism is that monitoring service is small
The variations in area, and support that channel quality recovers, to avoid unnecessary cell reselection and connection reconstruction process.
Radio Link monitoring and Radio Link Failure process in LTE have negative shadow for the switching in HetNet
Ring, it is specific as shown in Figure 2.UE current Serving cell is Pico cells, and UE is moved from Pico cells along the direction of arrow in the figure
Move Macro cells.With the movement of UE, the channel quality of Pico cells is gradually deteriorated, and when A points are moved to, UE is
Through continuously receiving N310 " step-out instruction ", now start T310 timers.Due to the limited coverage area of Pico cells,
When T310 timer expiries, UE has had moved out the coverage of Pico cells, it is impossible to recover the connection with Pico cells,
It is unnecessary that this connection re-establishes process.Therefore, existing RLF mechanism is no longer appropriate for heterogeneous network, it is necessary to be directed to heterogeneous network
The characteristics of optimize.
The application be directed to above-mentioned heterogeneous network the characteristics of, there is provided the method being monitored to Radio Link in, UE being capable of root
According to the difference of local environment, using the RLF parameters of different value sizes, the time of data-transmission interruptions is reduced, to adapt to difference
The demand switched under scene.If switching is more urgent, UE can earlier start RLF recovery processs, so as to capture earlier
The decline of serving cell channel quality.Correspondingly, UE can earlier the Serving cell good with channel quality adjacent cell set up
Connection.
The basic fundamental design of the application is differences of the UE according to handoff scenario, is adaptively adjusted the related ginseng of RLF processes
Several sizes.Self-adaptative adjustment RLF process related parameters are based on cell type.RLF process related parameters include T310, N310,
Qout and Qin.
To make know-why, feature and the technique effect of technical scheme clearer, below in conjunction with specific reality
Example is applied to be described in detail technical scheme.
Embodiment one：Type adjustment RLF parameters based on Serving cell
In heterogeneous network, different types of cell has different coverages, and UE cuts between different types of cell
The urgency level changed is different.For example, the urgency of the switching between Pico-Macro is far longer than between Macro-Macro
Switching, reason is that the transmission power of Pico cells is smaller, and when UE is away from Pico cells, the channel quality of Pico cells can be rapid
Ground declines, if UE cannot set up with Macro cells be as soon as possible connected, it is easy to the disconnecting with Pico cells can be caused,
Cause handoff failure.
According to the size of coverage, cell type can be divided into two classes：First kind cell and Equations of The Second Kind cell, wherein
The transmission power and coverage of Equations of The Second Kind cell are more than first kind cell.Equations of The Second Kind cell is typically macro base station cell, first
Class cell is usually LPN cells.UE according to the difference of serving cell types, using Qout the and N310 parameters of different values.
The method flow being monitored to Radio Link that the embodiment of the present application one is provided is as shown in figure 1, the flow is based on
The method that the radio link quality of aforementioned service cell is monitored, i.e., when UE receives continuous N310 " step-out instruction ", open
Dynamic timer T310；If during T310 timers run, UE is received continuous N311 " synchronizing indication ", and UE stops T310
Timer, continues to monitor the channel quality of Serving cell；If T310 timer expiries, there is Radio Link and lose in Serving cell
Lose, UE performs cell reselection process, while starting T311 timers；Step-out instruction refers to that the Signal to Interference plus Noise Ratio SINR of Serving cell is low
In the first threshold value Qout, " synchronizing indication " refers to that the SINR of Serving cell is higher than the second threshold value Qin.What embodiment one was provided
Flow comprises the following steps：
Step 301：UE obtain this UE where Serving cell cell type；
Step 302：If the cell type of the Serving cell is first kind cell, the N310 is set to N310_
1, the Qout is set to Qout_1；If the cell type of the Serving cell is Equations of The Second Kind cell, the N310 is set
N310_2 is set to, the first threshold value Qout is set to Qout_2；Wherein, the transmission power of Equations of The Second Kind cell and covering model
Enclose more than first kind cell, N310_1<N310_2, Qout_1>Qout_2.
The N310 is set to N310_1, the Qout is set into Qout_1 can be：Serving cell is special using RRC
It is that UE configures parameter { N310_1, Qout_1 } and { N310_2, Qout_2 } that 2 groups of Radio Links monitor correlation with signaling, UE is adopted
With { N310_1, Qout_1 }, the N310 is set to N310_1, the Qout is set to Qout_1；
The N310 is set to N310_2, the first threshold value Qout is set into Qout can be with 2：Serving cell
Using RRC dedicated signalings be UE configure the related parameters { N310_1, Qout_1 } of 2 groups of Radio Links monitoring and N310_2,
Qout_2 }, UE uses { N310_2, Qout_2 }, and the N310 is set into N310_2, and the Qout is set into Qout_2.
Using the method for this self-adaptative adjustment RLF parameters, UE can control the Startup time of wireless link recovery, that is, work as
When Serving cell is first kind cell, wireless link recovery process is started earlier, when Serving cell is Equations of The Second Kind cell, compared with
Start wireless link recovery process lately.
The cell type of Serving cell where UE obtains this UE can be in the following way：Base station in service sector is sent out to UE
Send system message or dedicated radio resources the control RRC signaling of the cell type for carrying this cell, system messages of the UE from reception
Or the cell type of Serving cell is obtained in dedicated RRC signaling.Or, the system that base station broadcast carries the cell type of itself disappears
Breath；UE receives the system message of Serving cell, and the cell type of Serving cell is obtained from the system message.
Embodiment two：The type adjustment RLF parameters of the adjacent cell based on Serving cell and Serving cell
In addition to the type of Serving cell, the adjacent cell of Serving cell（The Target cell for switching）Type can also influence
To switching urgency level, such as Macro-Pico, Pico-Macro, Macro-Macro, Pico-Pico switching correspond to respectively
Different demands.Therefore, UE, can be using different values according to Serving cell and the difference of the adjacent cell type of Serving cell
Qout and N310 parameters.
Embodiment two further optimizes than embodiment one, and also ratio method 1 is big for cost, because being available for the parameter combination that UE is selected
Number is 4 groups, and only 2 groups in embodiment one.Specifically, when the Serving cell of UE is first kind cell, Serving cell it is adjacent small

Zoom factor, environmental selections of the UE according to residing for one group of zoom factor therein carries out computing to the RLF parameters of benchmark, is worked as
The RLF parameters of preceding use.For example, if benchmark RLF parameters are { N310, Qout }, zoom factor is { N310_
Coefficient, Qout_coefficient }, then the RLF parameters that UE is finally used are { N310*N310_
coefficient,Qout*Qout_coefficient}.Specific to the present processes, for embodiment one, network is matched somebody with somebody for UE
