If in network side increase independently user profile collection, statistics and analysis module, the then multiple eNB of this model calling, the user profile collected is transferred to this module by each eNB, and this module in charge to comprehensive collection of user profile, and carries out statistics and analysis.As shown in Figure 1, this module through statistics and analysis can draw certain user regular in order through cell1-cell5, statistics also comprises the access times etc. of user to certain community.This module can such as, by relevant for statistics notice eNB, the eNB5 that eNB1 and cell5 that cell1 is corresponding is corresponding.Further, this module also can make rational prediction to the behavior of a certain strange user, such as, when taking the vehicles such as high ferro as user, its running route is fixed, and therefore, make a prediction in the community that this module can be about to arrive to the user taking high ferro, prediction according to comprising the now residing community of user, or a series of Serving cells etc. of process before.This module and can predict the outcome statistics and notify all relevant eNB, also only can notify in all relevant eNB one and several.
If between eNB the mutual switching historical information of UE or the historical information of cell configuration, eNB can record the community that user uses, and when community change occurs user, source eNB can pass to target eNB the historical information that the switching historical information of this UE or community use.As shown in Figure 1, when UE is altered to cell2 from cell1, the eNB1 that cell1 is corresponding notifies the historical information of cell1 Zeng Zuowei Serving cell the eNB2 that cell2 is corresponding, and eNB2 retains this information.By that analogy, when user moves to cell5, the information that corresponding eNB5 collected is: the Serving cell historical information of this UE is cell1-cell5, now, eNB5 carries out statistics and analysis to the behavioural information of this user, if often there is the Serving cell of cell1-cell5 in this user, then can draw certain user regular in order through cell1-cell5.ENB5 can by this statistics notice eNB1, or whole communities of notice cell1-cell4. further, if when user runs to cell3 from cell1, network side judges that this user takes high ferro, eNB3 can by notice eNB4, the eNB5 etc. of predicting the outcome.Particularly, can be that on user's traffic path, the switching historical information of UE or the historical information of cell configuration are collected in last base station, also can be specify what a base station to the historical information of the switching historical information or cell configuration of collecting UE in advance, this base station and can predict the outcome statistics and notify all relevant eNB, also only can notify in all relevant eNB one and several.
After UE current service eNB knows the community that UE will access, the cell access parameters of this community is issued UE by this eNB, such UE, after entering this community, need not carry out Signalling exchange with the eNB of this community, uses cell access parameters i.e. this community accessible stored.
Embodiment one
In the present embodiment, by RRC dedicated signaling, community carried out to UE by eNB pre-configured.
As shown in Figure 4, the mutual switching historical information of UE or the historical information of cell configuration between eNB, the switching historical information of UE or the historical information of cell configuration is collected by eNB1, when eNB1 obtain certain UE regular after the statistics of cell1-cell5, and when cell1 serves this UE again, cell access parameters cell1-cell5 is all sent to UE by the eNB1 belonging to cell1, and UE retains these cell access parameters after receiving these cell access parameters.
Cell management scene:
UE is when by cell1-cell5, and PCell (main plot) does not change all the time, for cell0, cell1-cell5 are all as the SCell (auxiliary community) of UE.
When UE select cell1 as Serving cell time (or, when UE enters the eNB0 belonging to cell0), eNB1 belonging to cell1 will pass through cell1-cell5 according to the Serving cell historical information of UE and/or traffic path prediction UE, the community configured information of cell1-cell5 is connected reallocation message by RRC and sends to UE, as wherein relevant to SCell configuration information, UE feeding back ACK/nack message is to eNB1; Also can be that the cell access parameters information of cell1-cell5 is sent to UE by RRC connection reallocation message by the eNB0 belonging to cell0, as wherein relevant to SCell configuration information, UE feeding back ACK/nack message be to eNB0.
After this, along with the movement of UE, give the correct time when UE triggers to measure, UE does not carry out Signalling exchange with eNB2, automatically bring into use the cell access parameters of the cell2 of storage to access cell2, for the cell access parameters of used cell1 before, UE can select to delete or continue to retain.When eNB1 receives the measurement report that UE reports, network side brings into use cell0+cell2 to carry out transfer of data to UE.
Cell merge scene:
Cell merge is there is in UE when passing through cell1-cell5.When UE selects cell1 as Serving cell, eNB1 belonging to cell1 will pass through cell1-cell5 according to the Serving cell historical information of UE and/or traffic path prediction UE, the community configured information of cell1-cell5 is connected reallocation message by RRC and sends to UE, as wherein relevant to cell merge configuration information, namely the information comprised in IEMobilityControlInfo, UE feeding back ACK/nack message is to eNB1.
After this, along with the movement of UE, give the correct time when UE triggers to measure, UE does not carry out Signalling exchange with eNB2, automatically bring into use the cell access parameters of the cell2 of storage to access cell2, for the cell access parameters of used cell1 before, UE can select to delete or continue to retain.When eNB1 receives the measurement report that UE reports, UEcontext (context) information is passed to eNB2 by eNB1, and the data be not transmitted is passed to eNB2 simultaneously, and after UE accesses eNB2, eNB2 starts to carry out transfer of data to this UE.
Embodiment two:
In the present embodiment, by broadcast mode or multicast mode, community carried out to UE by eNB pre-configured.
As shown in Figure 5, if there is the consistent situation of a large number of users behavior, as a large number of users is all got on the bus at same station, and get off at same station, then can to carry out community by broadcast mode or multicast mode to corresponding UE pre-configured for network side.
Cell management scene (for broadcast mode):
UE is when by cell1-cell5, and PCell does not change all the time, is that cell0, cell1-cell5 are all as the SCell of UE.According to the traffic path of UE, eNB0 predicts that a large amount of UE will pass through cell1-cell5, the community configured information of cell1-cell5 is comprised in the broadcast of eNB0, when UE enters the eNB0 belonging to cell0, UE reads the cell access parameters of cell1-cell5 from the broadcast of eNB0.After this, along with the movement of UE, give the correct time when UE triggers to measure, when entering into cell2 from cell1, UE does not carry out Signalling exchange with eNB2, automatically bring into use the cell access parameters of the cell2 of storage to access cell2, for the cell access parameters of used cell1 before, UE can select to delete or continue to retain.When eNB1 receives the measurement report that UE reports, network side brings into use cell0+cell2 to carry out transfer of data to UE.
Cell merge scene (for multicast mode):
Cell merge is there is in UE when passing through cell1-cell5.ENB0 organizes into groups the UE with same routes in advance, when the UE of the identical marshalling having some enters the eNB0 belonging to cell0, the community configured information of cell1-cell5 sends to these UE, UE feeding back ACK/nack messages to eNB0 by with multicast mode by eNB0.After this, along with the movement of UE, give the correct time when UE triggers to measure, when entering into cell2 from cell1, UE does not carry out Signalling exchange with eNB2, automatically bring into use the cell access parameters of the cell2 of storage to access cell2, for the configuration of used cell1 before, UE can select to delete or continue to retain.When eNB1 receives the measurement report that UE reports, UEcontext information is passed to eNB2 by eNB1, and the data be not transmitted is passed to eNB2 simultaneously, and after UE accesses eNB2, eNB2 starts to carry out transfer of data to this UE.
Embodiment three
In the present embodiment, it is pre-configured that eNB carries out community according to the conventional community of UE to UE.
As shown in Figure 6, the switching historical information of eNB according to UE or the historical information of cell configuration, the conventional community that UE access number of times is greater than preset value can be obtained, for the cell access parameters of conventional community, UE can retain voluntarily, or, when eNB sends community configured information to UE, wherein which is conventional community to instruction UE, namely which cell access parameters of UE is indicated to need when finishing using and maybe wouldn't using to continue to retain, when after UE, community is commonly used in access like this, just need not carry out Signalling exchange with the eNB of conventional community again, directly can utilize the conventional community of community access of the conventional community of storage.
Such as, when user is ridden to cell5 by cell1 direction, when UE selects cell1 as Serving cell, eNB1 belonging to cell1 will pass through cell1-cell5 according to the traffic path prediction UE of UE, the community configured information of cell1-cell5 is sent to UE, and indicate cell1-cell5 to be conventional community, UE is after the cell access parameters using cell1-cell5, continue the cell access parameters retaining cell1-cell5, like this when user is ridden to cell1 by cell5 direction, network side does not need again for UE issues the cell access parameters of these communities, UE can use the cell access parameters of reservation to access these communities voluntarily.Like this, the signaling consumption of network side can be reduced further.
For cell management scene, UE is when by cell5-cell1, and PCell does not change all the time, and for cell0, cell5-cell1 are all as the SCell of UE, when UE selects cell5 as Serving cell, UE uses the cell5 cell access parameters prestored automatically.After this, along with the movement of UE, give the correct time when UE triggers to measure, when entering into cell4 from cell5, UE brings into use the cell access parameters of cell4 automatically, and for the configuration of used cell5 before, UE can judge to carry out deleting or retaining according to network side instruction or UE voluntarily.When eNB4 receives the measurement report that UE reports, network side brings into use cell0+cell4 to carry out transfer of data to UE.
The invention provides a kind of at network side, user behavior to be collected, statistics and analysis, thus according to the community that UE is about to use, pre-configured method is carried out to UE.Wherein, the cell access parameters that UE is about to use can notify UE by eNB by broadcast mode or multicast mode; UE measures and gives the correct time, and the measurement result of neighbouring UE together can be reported eNB, or the measurement reported result of a UE can characterize the measurement result of one or more UE near it.Technical scheme of the present invention effectively can reduce Transmission time or the poor throughput time of UE, reduces PDCCH scheduling times, reduces signaling consumption, reduces UE power consumption simultaneously.
