When detecting multiple cells for supporting NSA ability, priority is resident according to the NSA terminal frequency point and is stayed
It stays.
It describes in detail below to the method for cell selection of the invention:
(1) for the improvement of network side equipment
1) increase cell ability mark in system broadcast message
Since NSA terminal is to have new UE ability, it is specific need to consider that network side equipment increases newly in system broadcast message
Field, guidance UE is resident or gravity treatment.It is bright to increase setting field list newly in system broadcast message, cell support NSA ability.
The field information amount is smaller, can be new in MIB (Master Information Block, host system message block)
Increase, it can also be newly-increased in other SIB.It specifically, can be in MIB or SIB (System Information Block, system information
Block) new field shows the meaning, by taking MIB as an example, as follows, underscore is expressed as new field, is 1 in the new field
When, show that the cell supports NSA.
That is NSAcapability-R15 represents the cell for " 0 " and does not support NSA ability, and " 1 " is that the cell supports NSA energy
Power.
2) NSA terminal is guided to be resident to specific frequency range cell in system broadcast message
To realize the guidance to NSA terminal, also needs to increase priority indication in system broadcast message, may make NSA
Terminal is resolved to different priority from LTE terminal.Can specifically following several schemes be used:
Scheme one: newly-increased NSA is resident or gravity treatment field, original SIB3 for being related to gravity treatment SIB4 SIB5 system broadcasts
In message, the field read for NSA terminal is increased newly, such as:
NSAcellReselectionInfoCommon-R15, NSAcellReselectionServ can be increased newly in SIB3
IngFreqInfo-R15 (including Snonintrasearch, threshServingLow and cellReselectionPriority) word
Section；
Increase NSAintraFreqNeighborCellInfo-R15 and NSAintraFreqBlackCellLi newly in SIB4
St-R15 field；
Increase NSAinterFreqCarrierFreqList-R15 field newly in SIB5.
For terminal its according to itself UE ability, according in system broadcast message information executive resident and gravity treatment.For
It according to newly-increased field carries out resident and gravity treatment to NSA capable terminal, and to non-NSA terminal, it is executed according to original field.
Scheme two: newly-increased part field instruction NSA is resident or gravity treatment priority, distinguishes resident priority to provide entirety,
Such as distinguish TDD or FDD.
Can in system broadcast message (MIB/SIB) new field: NSA Resident-R15INTEGER, value range
For (0..3),
NSA Resident-R15 be " 00 " indicate UE to TDD/FDD without priority, " 01 " indicates that UE is preferentially resident TDD net
Network, " 10 " indicate that UE is preferentially resident FDD network.
Scheme three: newly-increased part field, it (can be absolute value or opposite that the instruction specific frequency point of NSA terminal, which is resident priority,
Value), can in system broadcast message (MIB/SIB) new field: NSAcellReselectionPriority-R15, it is preferential
Grade is the priority value for NSA terminal.
3) NSA cell is preferentially switched to connected state UE
Network side equipment is relied primarily under connected state switches over (or redirection) control.If UE reporting ability supports NSA,
If this cell does not support NSA, network side equipment that can preferentially issue the adjacent area LTE when determining mobility switching and support NSA function
Measurement UE is actively switched into corresponding NSA cell and when eligible.
4) to eNB interface
ENB increases the field whether cell supports NSA ability newly in X2 interface message, interacts, is related to other eNB
In X2setup request and X2setup response field > Served Cell Information.It is specific increased
Field can be as shown in the table:
(2) for the improvement of subscriber terminal side
1) for not supporting the user terminal of NSA ability
Still follow existing cell it is resident/thresholding of gravity treatment, i.e., referring to cell in original SIB3, SIB4 with frequency and alien frequencies
Reselection information as, cellReselectionInfoCommon, cellReselectionServingFreqInfo,
InterFreqCarrierFreqList etc. carries out gravity treatment and is resident.
2) for the user terminal of support NSA ability
The user terminal of NSA ability is supported preferentially to select the cell for having NSA to identify in system broadcast message, and selection MIB/
Include the preferentially resident or gravity treatment of NSA ability label in SIB message.
It supports the user terminal of NSA ability, if detecting the cell of multiple NSA marks, then is increased newly according in SIB message
NSA frequency point priority be resident.
