Description
Technical field
The present invention relates to wireless communication technology field, more specifically under multicarrier environment, it is possible to efficient balance
The residence reselecting of cell load and terminal.
Background technology
In current LTE network (Release-12), after UE completes initial cell selection, receive the wide of community
Broadcast message, obtain the cell reselection priority information of current area frequency (i.e. servicing carrier frequency), obtain adjacent cell simultaneously
Cell-frequency list (be called for short adjacent frequency list), for each adjacent frequency in adjacent frequency list, system message comprises and it
Corresponding cell reselection priority information and corresponding cell reselection thresholding, UE carries out cell reselection according to information above.
In cell reselection process, if the cell reselection priority of adjacent frequency is higher than current area, as long as then certain is little in adjacent frequency
The RSRP (Reference Signal Received Power, Reference Signal Received Power) in district or RSRQ (Reference
Signal Received Quality, Reference Signal Received Quality) higher than cell reselection thresholding corresponding with this adjacent frequency
ThreshX, HighP or ThreshX, HighQ, and also UE is more than 1 second at the residence time of former Serving cell,
Then UE will be resident to this community by cell reselection process.
According to the real network statistical result of whole world Duo Jia LTE network operator, idle UE resident in community close
Positively related relation is there is between the data transfer loads of Du He community, and directly related with the access of community load, with
Upper cell re-selection mechanism is capable of idle UE equilibrium on different carrier cells under simple network design environment
Distribution, also therefore is able to successfully avoid cell data transmission load and the greatest differences of access load on different carrier frequency.
But, along with multi-transceiver technology and the development of small-cell (Small Cell) technology, the deployed environment of current network
Increasingly sophisticated, at the same area, it is understood that there may be three or even the frequency coverage of more than three, and different frequency is little
The coverage in district is also not quite similar (i.e. HetNet), under this network environment, above based on carrier frequency priority
In cell re-selection mechanism will cause a certain region, on the most resident carrier frequency the highest to priority of all of idle UE, from
And cause the data transfer loads being operated in the community of this carrier frequency and access overload, and the frequency that other priority are relatively low
Community in rate, loads the lightest, it is impossible to realize the purpose of load balancing.
Under the technological frame of current LTE system, for the community of overload, (Redirection) can be accessed by transfer
Or switching method part UE in community is transferred to adjacent frequency community, but, above two method is required to UE
Specific signaling instruction, this is by increasing the signaling traffic load of community, it addition, both approaches all can not fundamentally solve
The problem of load imbalance between different carrier frequency, because accessing by transfer or switched and transferred is to the UE of other communities, at it
After reentering idle condition, again by community corresponding for the resident carrier frequency the highest to priority, and these UE may weight
New initiation is accessed and data transfer request.Alternatively possible solution is by access barred (Access Barring)
Reduce the number of users accessed, and this method not only can not fundamentally solve the problem of load imbalance, also will cause using
The increase of family access delay, this is unacceptable for delay sensitive business.
Visible, under the network environment of multicarrier, sky cannot be realized according to the cell re-selection mechanism of carrier frequency priority at present
Not busy UE equiblibrium mass distribution between the community that different frequency is corresponding, and will further result in the data transmission of these communities
It is unbalance that load and access load, and ultimately results in the waste of Internet resources and the decline of Consumer's Experience.For this problem,
Still there is no preferable solution at present.

The restriction of the present invention.
The application is primarily directed to multicarrier network environment, and the cell re-selection mechanism defined due to current standard may
Too much idle UE can be caused to focus on the community being operated on the carrier wave that priority is the highest, cause on different districts
Load is unbalanced.In order to solve problem above, the present invention proposes the community under a kind of multicarrier network environment
Reselecting method, as it is shown in figure 1, this method enforcement step is as follows:
Step 110:UE obtains the load information of community, precedence information, and out of Memory.
Described community includes persistent district current for UE and adjacent cell, lower same.
Described load information includes access load information and the data transfer loads information of community of community.What is called connects
Entering load, embodiment is the number initiating the UE that RRC connection establishment is asked in community in certain time period；
So-called data transfer loads, embodiment be in community in certain time period the up and/or data ratio of downlink transfer
Special number, can be reflected as in community the utilization rate of up-downgoing running time-frequency resource in certain time period, or, community
RSRQ (Reference Signal Received Quality, Reference Signal Received Quality).Load is accessed for community
Can be defined by standard with the concrete calculation of cell data transmission load, or realize based on eNB.
UE can be by receiving eNB signaling or by measuring the load information obtaining community.If the former,
Then defined according to standard by eNB or cell load calculation that self implementation method determines calculate cell load,
And load information is mapped as respective value by signaling UE；If the latter, then UE is fixed according to standard
The calculation of justice, calculates the load information of community according to measurement result.
According to a kind of implementation of the application, described priority is corresponding with carrier frequency, is carrier frequency specific excellent
First level, the native region priority of same carrier is identical；According to the another kind of implementation of the application, described priority
The most corresponding with community, it is community certain priority, the native region priority of same carrier may be different.
Described priority can be relevant to UE ability, i.e. for same carrier frequency or community, if UE ability is different,
Then the priority in carrier frequency or community can be different.Such as, if MBMS is supported in a carrier frequency or community
(Multimedia Broadcast and Multicast Service, multimedia broadcast multi-broadcasting business), then for propping up
Holding the UE of MBMS function, priority corresponding to this carrier frequency or community is configurable to the highest, and for not propping up
Holding the UE of MBMS function, this carrier frequency or community are configurable to lower priority.
Out of Memory can include the gravity treatment probability P of communityi, gravity treatment probability can be that carrier frequency is specific or community is special
Fixed value, or all carrier frequency or community use identical gravity treatment probit, PiSpan be (0,1].

The specific priority in Tu2Wei community and gravity treatment probabilistic settings schematic diagram.Under configuration mode shown in Fig. 2,
Priority is all the most corresponding with community with gravity treatment probability, is the specific gravity treatment of community certain priority and community general
Rate, the native region priority of same carrier may be different, and gravity treatment probability is likely to difference.
Fig. 3 is the specific priority of carrier frequency and gravity treatment probabilistic settings schematic diagram.Under configuration mode shown in Fig. 3,
Priority is corresponding with carrier frequency with gravity treatment probability, is carrier frequency certain priority and carrier frequency is specific heavy
Selecting probability, the native region priority of same carrier is identical, and gravity treatment probability is the most identical.
Fig. 4 is carrier frequency certain priority and community specific gravity treatment probabilistic settings schematic diagram.In configuration side shown in Fig. 4
Under formula, priority is corresponding with carrier frequency, is carrier frequency certain priority, the cell preference of same carrier
Level is identical；And gravity treatment probability is corresponding with community, it is the specific gravity treatment in community probability, the weight of the community of same carrier
Select probability possible different.
Fig. 5 is UE ability certain priority and community specific gravity treatment probabilistic settings schematic diagram.Joining shown in Fig. 5
Putting under mode, priority is relevant to UE ability, i.e. for same carrier frequency or community, for the UE of different abilities
The priority that assignment configuration is different；And gravity treatment probability is corresponding with community, it is the specific gravity treatment in community probability, identical
The gravity treatment probability of the community of carrier frequency may be different.
