Description
Technical field
The present invention relates to cell management of the user terminal under idle states in wireless communication technique, more particularly to a kind of LTE
Method and apparatus.
Background technology
The key activities of IDLE states are related to selection of the terminal for physical area in the access layer of LTE protocol, be resident and
Gravity treatment.The cell type of LTE includes：Acceptable cell, suitable cell, reserves cell, banned cell, is restricted cell.
● acceptable cell：It can be only resident by UE to obtain restricted service（Initiate urgent call and receive ETWS
Message）.
● suitable cell：It can be resident by UE and obtain normal service（Initiate calling and business etc.）.Such cell must
The PLMN or EPLMN of registration must be belonged to, and cannot be prohibited, belong to legal tracing area, and meet that cell selects
Condition.
● reserved cell：Only some particular UEs can be resident, and can not be resident for other UE.
● banned cell：UE is forbidden to be resident.
● it is restricted cell：It can be resident, but forbid UE to initiate multi-upstream access.
For terminal, first thing during start for air interface is just an attempt to reside in suitable cell.
Before resident, radio resource control RRC is by search mechanisms by physical layer to fixed or unfixed frequency point and physical area I
D is scanned for, and is measured and read apparatus information to searching for successful cell.If the result of measurement and read apparatus information meets
The resident condition of success, then be resident in the cell.On the basis of resident, terminal can initiate the process of various multi-upstream access
And down-going synchronous receives new system information and the process of paging.
The criterion of cell selection is referred to as S criterions.This criterion refer to according to terminal measure cell RSRP values and reading
System information calculates a S value.If the S values of a cell are more than 0, then it represents that terminal can select the cell.
The cell selection of start, there is following two processes：
1. initial cell selects：
This process does not know which is E-UTRA carrier frequency in RF channels for terminal.Terminal needs to be scanned according to its ability
All RF channels, to find a suitable cell.Specifically, terminal will search for one most on each carrier frequency frequency point
Strong cell.Once finding suitable cell, which will be selected for being resident.
2. selected using the initial cell of storage information：
This process needs terminal to preserve a frequency point information even information list of cell parameter, if terminal is in lists
Suitable cell cannot be found to be resident, " initial cell selection " will be started.
Cell reselection refers to after terminal is resident successfully, can ceaselessly measure current service cell and adjacent cell
RSRP values.Terminal can recalculate RSRP values according to the parameter in cell system information, then accurate by a set of gravity treatment
Then choose whether to reselect in new cell.
Cell searching is carried out in end side and during gravity treatment, it is possible to it is following it is several in the case of there is multiple gravity treatment and cause
Redundancy.
One adjacent cell ranked first under cell reselection criterion, i.e., is determined as according to the gravity treatment brigadier cell optimal small
Area, but the cell is a banned cell（Terminal can not learn this situation before read apparatus information）.Therefore, cell reselection machine
System can always search for and attempt to be resident the cell, but can not be resident success.
It is banned cell to have multiple cells in adjacent cell, and this unknown situation of terminal, and terminal repeatedly gravity treatment may arrive this
One of a little banned cells, but can not also be resident success.
Serving cell is banned suddenly, is notified by system pages.But in the case where terminal does not have checking mechanism, still may be used
Energy meeting gravity treatment is to banned cell, so as to cause the resident and unsuccessful situation of multiple gravity treatment.
The above situation result in time and energy expenditure caused by unnecessary cell searching.

Embodiment
Below by drawings and examples, technical scheme is described in further detail.
Fig. 1 is cell selection and the residence reselecting of idle states user terminal in LTE according to embodiments of the present invention
Flow chart.
In step 101, one group of cell information is obtained in cell selection or cell reselection.
In step 102, the user terminals of idle states takes out a cell information from its known one group of cell information, and one
It is sent to physical layer comprising one or more cell informations, the cell information in group cell information and carries out cell searching,
The cell information can include cell i d and subdistrict frequency point.
In step 103, check that the cell information of taking-up whether there is in banned list, banned list is to pre-establish
In user terminal, CellBarredList [] can be described as.There may be multiple cell quilts according to current network state, in system
Prohibit.Preferably, the size of list can be set to 6, this is because in systems terminal gravity treatment when at most safeguard 6 banned cells
Information burden is smaller.For each single item in list, in addition to the cell information with banned cell, also maintain
One timer construction.The timer construction can be described as CellBarredTimer, to record the time for finding that cell is banned,
And the time limit that banned cell is lifted a ban in end side.
If it is present flow proceeds to step 104, otherwise flow proceeds to step 105.
In step 104, the cell information of inspection is deleted from one group of cell information, then flow returns to step
102。
In step 105, the cell information checked is sent to physical layer to scan for.
It is well-known to those skilled in the art that cell searching and cell, which are resident process, in order to avoid fuzzy of the invention, because
This is repeated no more.
Fig. 2 be idle states user terminal in LTE according to embodiments of the present invention cell selection and cell reselection in it is banned
The maintenance strategy schematic diagram of list.
In the following, the maintenance strategy of banned list is described in detail.
In step 201, user terminal is started shooting or is restarted.
In step 201, after user terminal is started shooting or restarted, the initialization function of protocol stack RRC is to banned list
Initialize installation is carried out, i.e., timer is reset and is set off its state, and the cell information in delete list item.
In step 203, when the SIB1 of system information is read, it is necessary to call the function of GC with check cell whether by
Prohibit.System information SIB1 can be read in the case of two kinds below.First, in cell searching flow, system information can be read
SIB1.Second, terminal receives paging in I DLE states, which is that prompt terminal system information changes, at this time
It is also required to re-read system information SIB1.
The cell or current service cell arrived in step 204, discovery cell current search is banned.
In step 206, traversal of lists scans for, and finds timer of the state for closing.
In step 208, a timer state is found in search procedure to close.
In step 210, the cell information of banned cell is written in this list items, and opens the timing in this
Device, sets banned cell to lift a ban the time limit in end side for timer.The timer opening time is the discovery cell banned time,
Lifting a ban the time limit could be provided as 300 seconds（The time span of protocol requirement）.If in short, do not have in lifting a ban in the time limit for timer
There is system information proactive notification, it may be considered that the corresponding cell of the timer remains in banned state.Timer-type can
Think disposable timer, that is to say, that be automatically closed more than timer after lifting a ban the time limit.
In step 212, when being automatically closed when the timer times out, i.e., cell is banned exceedes the timer predetermined banned phase
Limit, end side by the cell be considered as release it is banned.At this time, the cell information of this in banned list is deleted.
In step 209, find that the timer of all list items in banned list is completely in opening state in search procedure
State.
In step 211, the information of banned cell is not stored and is abandoned.Because being said from probability, while have more than 6
The banned situation in adjacent cell is fewer, and the cell information for abandoning banned cell has substantially no effect on system effectiveness.
In step 205, when system information SIB1 is read, it is necessary to call the function of GC with check cell whether by
Prohibit.When inspection result does not have banned for the cell, find that cell i d and subdistrict frequency point are deposited by searching for banned list
In some state is one of unlatching in banned list.
In step 207, delete the information of the banned cell of this and close corresponding timer.
No matter for which kind of reason, cell information is deleted and the corresponding pent list items of timer can be considered can
With item, i.e., when there is new banned cell information to need to write banned list, can be operated using this.Above-mentioned is banned
The actual purpose of list is to tell RRC, current time which adjacent cell for user terminal be banned, i.e., cannot stay
Stay.The function of banned list is the idle states for RRC, because connection（connected）The cell switching of state is by network
Side controls, and network side will not allow terminal to be switched to a banned cell.So only carried out in idle states user terminal
Cell just uses this list when selecting with cell reselection.In short, by using the banned list, can be by the quilt in the list
Prohibit cell filtering to fall, i.e., physical layer does not have to search for the banned cell in subsequent step.
Fig. 3 is the flow chart of the cell selecting method of idle states user terminal in LTE according to embodiments of the present invention.
After step 301, starting up of terminal, the process for reading SIM card is booted up in Non-Access Stratum NAS.
In step 302, search for and select PLMN.By reading SIM card, if it find that terminal does not preserve prior information, then
Full frequency band search is carried out, the cell information of most strong cell is searched on each carrier frequency frequency point and is reported to NAS layers, by NAS
Layer decides whether to continue PLMN search；If it find that terminal preserves prior information, then NAS layers of instruction access layer AS according to
The parameter of prior information carries out PLMN search.Then, the PLMN of high quality is therefrom selected according to the search result of PLMN.
In step 303, NAS sends the cell searching request of selected PLMN to RRC and the cell of some cells to be searched is believed
Breath.In the case where terminal does not store cell information, full frequency band search is carried out, most strong cell is searched on each frequency point,
And the cell information searched is sent to RRC；In the case where terminal storage has cell information, the cell information of storage is sent out
It is sent to RRC.Being sent to one group of cell information of RRC includes cell i d and subdistrict frequency point, and the cell information of these selections is used to treat
Physical layer scans for.
In step 304, RRC takes out the cell letter of a cell to be searched from the cell information of one group of cell to be searched
Breath.
In step 305, RRC checks that the cell information for the cell to be searched taken out whether there is in banned list.If
In the presence of then flow proceeds to 106；If it does not exist, then flow proceeds to step 307.
In step 306, the cell information of the generation search cell of taking-up is removed from the cell information of some cells to be searched,
Then flow returns to step 304.
In step 307, the cell information of cell to be searched is sent to physical layer to scan for.
Fig. 4 is the flow chart of the residence reselecting of idle states user terminal in LTE according to embodiments of the present invention.
In step 401, RRC receives the cell of current persistent district and some adjacent cells after gravity treatment triggering from physical layer
Measurement result.RRC can send the measurement request of serving cell when gravity treatment triggers, by interacting for MC in RRC and physical layer,
The measurement result of current persistent district and some adjacent cells is finally received from physical layer.
In step 402, cell is screened according to cell measurement results and system information, selects and meets the small of S criterions
Area.
In step 403, the cell measurement results after screening are ranked up according to the native region priority in system information.
In step 404, a cell information is taken out from the corresponding one group of cell information of measurement result after sequence.
In step 405, check that the cell information of taking-up whether there is in banned list.If it is present flow carries out
To step 406, otherwise flow proceeds to step 407.
In step 406, the cell information of the taking-up is deleted from one group of cell information, then flow returns to step
Rapid 404.
In step 407, priority judgement is carried out according to the native region priority of the cell information of the taking-up.
In step 408, the cell information and its priority court verdict are sent to physical layer to scan for.
