Embodiment
Below with reference to accompanying drawings preferred implementation of the present disclosure is described in more detail.Although show preferred implementation of the present disclosure in accompanying drawing, but should be appreciated that, the disclosure can be realized in a variety of manners and not should limit by the execution mode of setting forth here.On the contrary, provide these execution modes to be to make the disclosure more thorough and complete, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Usually, UE historical information comprises the information of the respective cell accessed about this UE, and this respective cell refers to that before Target cell and UE is in the community of connection (active) state wherein.UE historical information also comprises: past visited cell list (Last VisitedCell List) and in the past visited cell information (Last Visited Cell Information), wherein, past visited cell packets of information is containing global cell identity (Global Cell ID), cell type (Cell Type), the UE time of staying in the cell (Time UE stayed in Cell), UE granularity enhancingization time of staying in the cell (Time UE stayed in CellEnhanced Granularity) and cause switching value (HO Cause Value).
In TS36.300, describe following mechanism:
As long as UE is arranged in one of them community of source base station, source base station is just collected and is stored the historical information of UE.When list is with full, when needing to delete some information, the order by its position is in lists removed, from the community of recording the earliest by these information.By interface S1 and X2 transmission history information, and it is used in follow-up switching preparation, the list of this community previously accessed for target BS provides and relevant information.Switch preparation routine also to go to start to collect and store UE historical information in trigger target base station, and therefore transmit the information collected.
Technique scheme is only applicable to single connection system, in dual link system, UE is connected to dominant base (MeNB) and prothetic group station (SeNB) simultaneously, and technique scheme does not solve the information about how to record MeNB and SeNB community simultaneously.Iff the information of record MeNB community, that cannot estimate mobile status thus configuration-system parameter exactly, and that is in prior art, the user history information of dual link system is incomplete.
In order to intactly record the user history information of dual link system, we need the mechanism of the UE historical information defined in dual link system.
In dual link system, the historical information being simultaneously connected to SeNB and MeNB about UE will be collected and will be recorded in UE historical information.As long as connect in one of them community of UE and source base station, source base station is just collected and is stored the historical information of UE, thus as in single connection scheme, can obtain the historical information of complete UE, thus can estimate exactly user velocity.
In the present embodiment, the method identical with single connection transmission method is adopted to transmit the UE historical information in dual link system.Be included in handover request by UE historical information, this request is sent to target BS by source base station, the preparation switched with request resource.In addition, UE historical information not only comprise about before Target cell, UE is the information of community of the MeNB of connection status wherein, also comprises the information of the community about SeNB.
Be contained in the past visited cell list in UE historical information and in the past in the information of visited cell, the information of MeNB community and SeNB community is being stored with independently community form information respectively.This past visited cell information also comprises: global cell identity, cell type, the UE time of staying in the cell, UE enhancing granularity time of staying in the cell and cause switching value.For SeNB, cause switching value can increase at " the prothetic group station (SeNB in Dual Connectivity) in dual link ", thus can mark SeNB, be convenient to record.
By aforementioned known, in dual link system, in order to estimate exactly the mobile status/speed of UE, need the information as far as possible intactly recording the base station be connected with UE, namely need the information recording MeNB and SeNB be connected with UE.Below respectively the historical information how recording two kinds of eNB is set forth.
In the present embodiment, the process of the historical information of record MeNB is consistent with recording process in single connection system, namely sent by source base station (Source eNB) and handover request to target BS (Target eNB), thus trigger target base station starts to collect and stores UE historical information, and receive the historical information being included in the UE in handover request from source base station.
For SeNB, when MeNB successfully complete for UE the community of new SeNB increased be auxiliary community time, or send when increasing request to SeNB for adding, MeNB starts to collect the ID of time that UE stops in this SeNB community and this auxiliary community.If MeNB determines this SeNB of release, or when receiving the releasing request from SeNB, the record that MeNB will complete for the time resting on this auxiliary community, and all packets of information are contained in the historical information of UE.If MeNB determines to switch to Target cell (i.e. another one MeNB), and this UE still can keep connecting with the current SeNB be connected, this Target cell will after UE completes and switches to Target cell, continue the historical informations such as the time of staying of the collection community of UE in SeNB, until UE and SeNB disconnects.
In order to more clear, set forth content of the present invention visually, refer to Fig. 2-4.
Fig. 2 be according to the embodiment of the present invention in same dominant base community, UE switches auxiliary base station cell schematic diagram.
As shown in Figure 2, UE is arranged in dominant base MeNB1 community, then MeNB1 will collect the historical information of UE, such as, global cell identity, cell type, the UE time of staying in the cell, UE enhancing granularity time of staying in the cell and cause switching value.
When UE moves to the edge of SeNB1 community, prothetic group station, during such as, A point in figure, dominant base MeNB1 will be added to the auxiliary community of UE by the community of prothetic group station SeNB1, and add up the relevant information of UE in this auxiliary community.
Can be specifically, dominant base MeNB1 can send and add request to prothetic group station SeNB1, or dominant base MeNB1 completes when the community of prothetic group station SeNB1 being added to auxiliary community (namely receiving the feedback from prothetic group station SeNB1), dominant base MeNB1 starts to record the time of staying of UE in the community of prothetic group station SeNB1 and the mark of SeNB1 community, prothetic group station.In order to mark auxiliary community, can increase and cause switching value, such as can be " the prothetic group station in dual link ".
When UE moves to the cell edge of prothetic group station SeNB1 simultaneously in dominant base MeNB1 community the community of prothetic group station SeNB1 (be also), need to discharge prothetic group station SeNB1.For the process of release, when dominant base MeNB1 determines release prothetic group station SeNB1, or dominant base MeNB1 is when receiving the releasing request from prothetic group station SeNB1, the information of UE in auxiliary community by the stopping record time of staying of UE in SeNB1 community, prothetic group station, and is recorded in historical information by dominant base MeNB1.Be understandable that, releasing request is for disconnecting the connection of the community of UE and prothetic group station SeNB1.
Therefore, the historical information of UE now comprises: the information of (1) dominant base MeNB1 community; (2) information of prothetic group station SeNB1 community.
Along with UE moves in dominant base community, UE moves to the cell edge of prothetic group station SeNB2, such as B point, and dominant base MeNB1 performs aforementioned process again, and the community of namely adding prothetic group station SeNB2 is Xin Fu community, and is recorded in the historical information of UE in auxiliary community.
Equally, when UE moves to the cell edge of prothetic group station SeNB2 simultaneously in dominant base MeNB1 community the community of prothetic group station SeNB2 (be also), need to discharge prothetic group station SeNB2.When dominant base MeNB1 determines release prothetic group station SeNB2, or dominant base MeNB1 is when receiving the releasing request from prothetic group station SeNB2, the information of UE in auxiliary community by the stopping recording user time of staying of equipment in auxiliary community, and is recorded in historical information by dominant base MeNB1.Be understandable that, releasing request is for disconnecting the connection of the community of UE and prothetic group station SeNB2.
Now, the historical information of UE comprises: the information of (1) dominant base MeNB1 community; (2) information of prothetic group station SeNB1 community; (3) information of prothetic group station SeNB2 community.
In some occasion, may there is the phenomenon of overlapping (overlap) as shown in Figure 3 in the community at prothetic group station.Fig. 3 be according to the embodiment of the present invention in same dominant base community, UE is in the schematic diagram of the overlapping region of auxiliary base station cell.
Now, UE is positioned at overlapping position, the community of prothetic group station SeNB1 and prothetic group station SeNB3, such as C point.For dual link system, UE can only select one and connect as prothetic group station in base station SeNB1, SeNB3.Therefore, for SeNB1, SeNB3 community, overlapping situation occurs, dominant base MeNB1 can make last decision and add which base station (SeNB1 or SeNB3) for prothetic group station.Such as select SeNB1 as prothetic group station, dominant base MeNB1 performs aforementioned process again, and the community of namely adding prothetic group station SeNB1 is Xin Fu community, and is recorded in the historical information of UE in auxiliary community.When UE moves to the cell edge of prothetic group station SeNB1 simultaneously in dominant base MeNB1 community the community of prothetic group station SeNB1 (be also), need to discharge prothetic group station SeNB1.When dominant base MeNB1 determines release prothetic group station SeNB1, or dominant base MeNB1 is when receiving the releasing request from prothetic group station SeNB1, the information of UE in auxiliary community by the stopping recording user time of staying of equipment in auxiliary community, and is recorded in historical information by dominant base MeNB1.Be understandable that, releasing request is used for the connection of the community by disconnecting UE and prothetic group station SeNB1.
Fig. 4 is the schematic diagram of UE at dominant base handover between cells of the foundation embodiment of the present invention.
When UE is by during from the cell merge of dominant base MeNB1 to the community of dominant base MeNB2, the Information Statistics of UE that dominant base MeNB1 will terminate the community being arranged in dominant base MeNB1, and send comprise UE historical information handover request to target dominant base MeNB2, the preparation switched with request resource.
In order to allow dominant base MeNB2 can obtain complete UE historical information, the UE historical information that the community of dominant base MeNB1 sends comprises: the information of (1) dominant base MeNB1 community; (2) information of prothetic group station SeNB1 community; (3) information of prothetic group station SeNB2 community; (4) information of prothetic group station SeNB4 community.
If UE now still can keep with current auxiliary community being connected, when for example UE will move to the overlapping region of SeNB4 community, prothetic group station and target BS (i.e. dominant base MeNB2) community, dominant base MeNB1 will determine that the main plot of UE will switch to the community of dominant base MeNB2, and therefore transmission is handovered request to dominant base MeNB2 by dominant base MeNB1.This handover request comprises the historical information of above-mentioned UE.After UE completes the process switching main plot (namely UE is formed with dominant base MeNB2 and is connected), because it is still in the community of prothetic group station SeNB4, D point for example in figure, that now carry out dual link with UE is dominant base MeNB2 and prothetic group station SeNB4, the community of prothetic group station SeNB4 is still the auxiliary community of UE, therefore continuation is collected the time of staying of UE in SeNB4 community, prothetic group station, until UE and prothetic group station SeNB4 disconnects by dominant base MeNB2.
By above-mentioned method, the link information of the prothetic group station SeNB4 community of UE in dominant base MeNB1 community, also received by dominant base MeNB2, thus can ensure that the integrality of the historical information of UE.
The present invention proposes a kind of mechanism that UE historical information is provided in dual link system.By this mechanism, communication network can intactly record " cell information of the work in dual link and the information of MeNB and SeNB ", thus effectively can perform MSE, and the parameter configuration of optimized network.
Be understandable that, foregoing also goes for the system that two or more connects.In addition, Fig. 2-4 only lists comparatively common scene, but method of the present invention is also applicable to other unlisted scene, such as the situation that plural MeNB and/or SeNB community overlaps etc.
In the present invention, the historical information of UE comprises its all community (no matter be single connection state or dual link state, comprise dominant base community and auxiliary base station cell) stopped, and therefore, network can carry out optimized configuration.By method of the present invention, the community of all connections will be recorded, and enough information can be provided to supply moving speed estimation.In addition, for low background traffic business, mobile message will indicate (PPI:Power PreferenceIndication) conbined usage with power preference.Consider that the business shunted by SeNB is (best effort) business of doing one's best substantially, these information are very useful to the resource distribution of network side.
