The specific embodiment introduction of the present invention is given below.
Embodiment 1：RRC is idle（idle）State, the UE of D2D functions is supported to carry out D2D cell selections.
The corresponding instruction of eNB broadcast, informs whether UE current base stations support the D2D functions of correlation；Support D2D functions
UE, if current persistent district does not support the D2D functions of correlation, the UE starts D2D cell selection functions, and UE passes through D2D cells
After the cell for supporting related D2D functions is resident in selection, the frequency where the cell is set to limit priority, and carry out
D2D cell reselections.
Network side：
Pass through system message（Such as SIB1 or new SIB）, eNB broadcast the cell support D2D functions；Because D2D is serviced
It is divided into again close to service discovery and close to communication for service, therefore can further indicate that support close to service hair in system message
Show function and/or support close to communication for service function.
UE sides：
The RRC idle state UE of D2D functions are supported, if current persistent district does not support D2D functions, it is small that the UE starts D2D
Area's selection course or D2D cell reselection process.
D2D cell selection procedures are specially：Do not consider cell reselection priority, but according to all around the search of its ability
Available E-UTRA frequencies, and system information at least is read to signal quality optimum subdistrict on each E-UTRA frequencies, confirm it
Whether D2D function is supported, if signal quality is optimal on certain frequency（Or sequence highest）Cell supports D2D functions, and meets
Properly（suitable）The condition of cell, then UE choose the cell, the frequency where the cell is set to limit priority, and
Stop D2D cell selection functions, carry out D2D cell reselection process；If not finding suitable D2D cells, UE can be regular
Carry out D2D cell selection functions, its cycle may depend on UE realization.
If network side will support D2D functions to be further designated as supporting close to service discovery function and/or support close
Communication for service function, then UE lateral roots are according to itself possessed function and network side possessed D2D functions, startup D2D cell choosings
Select and/or the condition of D2D cell reselection functions and process some changes.For example, possessing the UE close to service discovery ability, then exist
When persistent district is not supported close to service discovery function, start the selection of D2D cells and/or D2D cell reselection functions；D2D cells
In selection course, it is also desirable to which the D2D cells close to service discovery function are supported in selection, can just stop D2D cell selection functions.Tool
The standby UE close to communication for service ability, the condition and process for starting D2D selections and/or D2D cell reselections also have similar change；Such as
Fruit UE had both possessed close to service discovery ability or possessed close to communication for service ability, then UE, which only needs to choose, supports close to service
Discovery feature or support close to communication for service function cell.
D2D cell reselection process can have two kinds of implementations：
The first：In D2D cell reselection process, UE only carries out cell reselection judgement, cell to the D2D cells searched
Gravity treatment judgment rule is as existing cell reselection rules；Only when currently without suitable D2D cells, just perform general
Logical cell selection or reuse adoption process, and above-mentioned D2D cell selection procedures are carried out simultaneously；
Second：In D2D cell reselection process, if serving cell or adjacent cell are D2D cells, meeting during cell reselection
Increase special D2D parameters, so as to allow UE longer time, be easier to choose D2D cells, specific embodiment can be found in embodiment
3（Note：During this, including D2D cells and normal cells）.
Embodiment 2：RRC idle states, the UE for opening D2D functions carry out D2D cell selections.
Except that, when supporting the UE of D2D functions to open D2D functions, or/and D2D functions are set to by UE with embodiment 1
During limit priority, if current persistent district does not support the D2D functions of correlation, the UE just start D2D cells selection function or
D2D cell reselection process.
Network side：
Pass through system message（Such as SIB1 or new SIB）, eNB broadcast the cell support D2D functions；Or to broadcast this small
Support close to service discovery function and/or support close to communication for service function in area.
UE sides：
The RRC idle state UE of D2D functions are supported, if D2D functions are not opened, or/and D2D functions are not set to highest by UE
During priority, then UE only carries out normal cell reselection；When UE opens D2D functions, or/and that D2D functions are set into highest is excellent by UE
During first level, if current persistent district does not support the D2D functions of correlation, the UE just starts D2D cells selection function or D2D is small
Area's reuse adoption process, D2D cell selection procedures are same as Example 1, and possible difference is that now D2D cell selection periods can
To be realized depending on UE, or informed by D2D Service application layers；It is small subsequently also to carry out D2D after D2D cells are chosen by UE
Area's gravity treatment, with embodiment 1.
When UE closes D2D functions, or when D2D functions are no longer set to limit priority by UE, then UE is closed accordingly
D2D cell selection procedures or D2D cell reselection process（If carry out at that time）, also no longer by the D2D cells institute of correlation
Frequency be set to limit priority.
If network side will support D2D functions to be further designated as supporting close to service discovery function and/or support close
Communication for service function, then start the condition and process of D2D cells selection function or D2D cell reselections some changes, such as have
The standby UE close to service discovery ability, it will be set to when UE is opened close to service discovery function, or/and UE close to service discovery function
During limit priority, D2D cells selection function or D2D cell reselections can be just opened；D2D cell selection procedures are also for seeking
Look for the D2D cells supported close to service discovery function.
Embodiment 3：ENB is for supporting D2D functions to broadcast special cell reselection parameters.
ENB be D2D cell reselections broadcast some special cell reselection parameters, so as to allow possess D2D functions UE, open
The UE of D2D functions or/and D2D functions are set to limit priority（It is or interested）UE, it is earlier or longer resident
In D2D cells；After above-mentioned UE is resident D2D cells, if the frequency where the cell is not limit priority, by the frequency
It is set to limit priority.
Such as：Increase the offset of D2D cells, UE is when carrying out the cell reselection with frequency or same priority alien frequencies, more
Easily choose D2D cells.
Network side：
In addition to broadcasting existing cell reselection parameters, if eNB possesses D2D functions, one extra service of broadcast is small
The hysteresis Q of area's priority parametershyst_D2D；If possessing the adjacent area of D2D functions, an extra neighbour is broadcasted for the adjacent area
The deviant of native region priority parameter（offset）, i.e. Qoffsets,n_D2D。
UE sides：
Currently, Idle states UE is carried out small when carrying out the cell reselection with frequency or same priority alien frequencies by R criterions
Area's gravity treatment.In R criterions, Rs represents serving cell priority parameters, and Rn represents neighbor cell priority parameter, is defined as follows:
Rs=Qmeas,s+QHyst
Rn=Qmeas,n-Qoffset
Wherein：Qmeas represents Reference Signal Received Power in cell reselection（Reference signal received
Power, RSRP）Measured value.QHyst represents hysteresis, is set for serving cell, it can be understood as certain cell is as clothes
