Usually, UE historical informations include information about the respective cells accessed the UE, the respective cell refer to Before Target cell and UE is in the cell of connection (active) state wherein.UE historical informations further include:Past accesses Cell list (Last Visited Cell List) and in the past access cell information (Last Visited Cell Information), wherein it includes global cell identity (Global Cell ID), cell type that the past, which accesses cell information, The granularity enhancing of (Cell Type), UE residence time (Time UE stayed in Cell) in the cell, UE in the cell Change the residence time (Time UE stayed in Cell Enhanced Granularity) and causes switching value (HO Cause Value)。
In TS36.300, following mechanism is described:
As long as UE is located in one of source base station cell, source base station is just collected and stores the historical information of UE.Work as row Table has been used full, and when needing to delete some information, these information will be removed by the sequence of its position in lists, from most The cell early recorded starts.By interface S1 and X2 transmission history information, and by it in subsequent switching preparation, this to be mesh Mark base station provides the list of the cell previously accessed and relevant information.Switching preparation routine also triggers target BS and goes out Begin to collect and store UE historical informations, and therefore transmits collected information.
Above-mentioned technical proposal is only applicable to single connection system, and in doubly-linked welding system, UE is connected to master base station simultaneously (MeNB) and prothetic group station (SeNB), above-mentioned technical proposal record the letter of MeNB and SeNB cells there is no solution simultaneously Breath.If only the information of record MeNB cells, that will be unable to accurately estimate mobile status to configure systematic parameter, also It is to say in the prior art, the user history information of doubly-linked welding system is incomplete.
In order to completely record the user history information of doubly-linked welding system, it would be desirable to define in doubly-linked welding system The mechanism of UE historical informations.
In doubly-linked welding system, being connected to the historical information of SeNB and MeNB simultaneously about UE will be collected and be recorded in UE In historical information.As long as establishing connection in one of UE and source base station cell, source base station is just collected and stores the history of UE Information, so as to as in single connection scheme, obtain the historical information of complete UE, so as to be carried out to user velocity Accurately estimate.
In the present embodiment, using method identical with single connection transmission method to the UE historical informations in doubly-linked welding system into Row transmission.UE historical informations are included in switching request, which is sent to target BS by source base station, to ask resource to be cut The preparation changed.In addition, UE historical informations include not only about before Target cell, UE be wherein connection status MeNB The information of cell also includes the information of the cell about SeNB.
In the past in being contained in UE historical informations accesses cell list and accesses cell information in the past, by MeNB cells It is stored respectively with independent cell form information with the information of SeNB cells.The past accesses cell information:Entirely Office's cell ID, cell type, UE residence times in the cell, UE enhancing granularity residence time in the cell and cause Switching value.For SeNB, cause switching value that can increase for " prothetic group station (the SeNB in Dual in dual link Connectivity) ", so as to which SeNB is marked, convenient for record.
By aforementioned it is found that in doubly-linked welding system, accurately estimated in order to mobile status/speed to UE Meter, needs the information for recording the base station being connect with UE as completely as possible, that is, need the MeNB that was connect with UE of record and The information of SeNB.The historical information for how recording two kinds of eNB is illustrated individually below.
In the present embodiment, the process for recording the historical information of MeNB is consistent with recording process in single connection system, i.e., logical It crosses source base station (Source eNB) transmission and handovers request to target BS (Target eNB), start to search to trigger target BS Collect and store UE historical informations, and receives the historical information of the UE being included in switching request from source base station.
For SeNB, when MeNB successfully complete for UE by the cell of new SeNB increase for secondary cell when, or hair It send when increasing request to the SeNB to be added, MeNB starts to collect UE residence time and secondary cell in the SeNB cells ID.If MeNB determine discharge the SeNB, or receive from SeNB release request when, MeNB will complete for resting on The record of the time of the secondary cell, and will be in historical information of all packets contained in UE.If MeNB is determined to switch to Target cell (i.e. another MeNB), and the UE remains able to keep connecting with the SeNB currently connecting, and the target is small It will continue to collect the historical informations such as the residence times of cell of the UE in SeNB, directly after UE completes to switch to Target cell in area It is disconnected to UE and SeNB.
In order to it is apparent, visually illustrate present disclosure, please refer to Fig. 2-4.
Fig. 2 be according to the present invention embodiment in same master base station cell, UE switches auxiliary base station cell schematic diagram.
As shown in Fig. 2, UE is located in master base station MeNB1 cells, then MeNB1 will collect the historical information of UE, for example, global Cell ID, cell type, UE residence time in the cell, UE enhancing granularity residence time in the cell and cause Switching value.
When A points when UE is moved to the edge of prothetic group station SeNB1 cells, such as in figure, master base station MeNB1 will be prothetic group The cell of SeNB1 of standing will be added to the secondary cell of UE, and count relevant informations of the UE in the secondary cell.
