Embodiment
At first, the term that relates among the application is made an explanation.
MUE (macro base station under subscriber equipment): the UE (User Equipment, subscriber equipment) of (Closed Subscriber Group, the closed user group) ability that refers to there is not CSG fully; For certain low power base station (as: Home eNodeB HNB/HeNB), be non-member's UE perhaps, the CSG ID (closed subscriber group identity) of this low-power Home eNodeB is not in the CSG of UE white list;
Low power base station, as: Home/Pico/Femto/Relay for ease of explanation, will be that example is described low power base station with Home eNodeB HNB/HeNB mainly among the application;
HNB: Home eNodeB Home Node B or Home eNode B;
MNB: macro base station.
The inventor notices in the invention process:
One, cell pattern is divided.
Three kinds of sub-district access modules under the HNB/HeNB are:
1, open mode (Open access mode): be used as normal cell (normal cell) and operate similar macrocell.
2, closed mode (Closed access mode): be used as the CSG sub-district and operate.
3, mixed mode (Hybrid access mode):, also allow non-CSG member to insert simultaneously though be the CSG sub-district.
HNB in this patent all refers to the sub-district/HNB of closed mode, and promptly non-member UE does not allow to insert.
Two, cell selecting.
Cell selecting has two kinds of processes, is respectively that initial cell is selected and the stored information cell selecting.
The stored information cell selecting: the selection of this process needs the stored information of carrier frequency and optional cell parameter information.Parameter can be with coming from former measuring control information or former detected sub-district.In this process, if find suitable cell, UE is with resident.If do not find suitable cell, UE will start the initial cell selection course.
Initial cell is selected: the selection of this process need not the prior information of E-UTRA (E-UTRAN:Evolution-Universal Terrestrial Radio Access, the global terrestrial wireless of evolution inserts) carrier wave RF (RadioFrequency, radio frequency) channel.UE will remove to find suitable cell according to all the RF channels in the ability scanning E-UTRA frequency band of oneself.On each carrier wave, UE only need search for the strongest sub-district.In case the discovery suitable cell, this sub-district is with selected.
Cell selecting in this process is read system information or dedicated signaling not, only judges through signal strength signal intensity and signal quality.In case UE finds the strongest sub-district on certain frequency and satisfies the S criterion, then attempts inserting.
The S criterion formulas, whether the signal strength signal intensity and the quality of a certain sub-district that assessment UE records satisfy certain condition simultaneously:
Because a MUE possibly start shooting in the stronger geographic area of HNB signal and get into the cell selecting process; This may cause selecting HNB to attempt inserting immediately after this UE start; If this UE is not the member UE of this HNB, then will attempt selecting other sub-districts to insert behind this UE access failure.
Three, district reselecting.
Cell reselection process need sort to the sub-district that UE measures, and UE carries out the gravity treatment to highest ranked (highest ranking, the former speech in the agreement is highest ranked, looks like to be meant that signal strength signal intensity is best) sub-district.When the best sub-district of this signal strength signal intensity is the non-member HNB of UE, UE will not consider that this sub-district is the candidate cell of gravity treatment, and on frequently, continue to consider other sub-districts.If the CSG ID of HNB is not among the CSG of UE white list, UE will can normally not reside in this HNB, but continue to consider that other sub-districts with on the frequency are the candidate cell of its gravity treatment.
Four, MUE gets into the covering cavity of HNB.
Fig. 1 gets into the covering cavity sketch map of HNB for MUE, and is as shown in the figure, for the situation of closed mode Home eNodeB, establishes UE1 and belongs to macro base station, and UE2 is CSG user, and HNB only can authorization of service CSG user; So because UE2 is CSG user, so can the authentication access to family base station.When UE1 is positioned at the coverage of HNB; Because UE1 is different from UE2; Be not the CSG user's (also being that UE1 is MUE) who authorizes, even the HNB signal strength signal intensity is higher than the signal strength signal intensity at grand station far away, UE1 also can't switch to HNB and will receive the strong jamming from HNB.The non-constant of channel condition that so just might cause user UE1 produces call drop, or even can't work.In existing LTE (Long TermEvolution, the Long Term Evolution) agreement,, therefore can't solve the descending interference problem under the above-mentioned situation owing to can not carry out power control through the adjacent area interference of reporting of user or the RST of this sub-district.
From the above, if MUE gos deep into the coverage of HNB, along with HNB strengthens the interference of MUE, MUE can't be under the coverage of macro base station operate as normal.But MUE does not possess the ability that inserts HNB again, and good HNB works on can't to insert signal quality.If the entering that HNB can not perception MUE then can't be adopted such as methods such as power controls to alleviate owing to cover the interference to MUE that cause in the cavity.
Therefore, the key issue of solution is: current do not have technical scheme can make the HNB can perception MUE as yet, just can't adopt such as methods such as power controls to alleviate owing to cover the interference to MUE that cause in the cavity yet.
Given this; In the technical scheme that the embodiment of the invention proposes; Proposed when non-Member Users gets into the covering cavity of being caused by low power base station, made the technical scheme of the existence that low power base station can the non-Member Users of perception, thereby can take measures (such as: power control) alleviate self interference to non-Member Users; Can keep non-Member Users's working signal as much as possible, improve non-Member Users and cover the user experience of empty situation at this.
Describe below in conjunction with the accompanying drawing specific embodiments of the invention.
In declarative procedure, the enforcement from UE and low power base station side describes at first respectively, for better understanding enforcement of the present invention; And then the cooperation of the two implemented to describe, but this and do not mean that the two must cooperate enforcement, in fact; When UE and low power base station are separated when implementing; Its UE side that also solves separately, the problem of base station side when just the two is used in combination, can obtain better technique effect.
Mobility under the IDLE state is by the UE Autonomous Control.Do not have between UE and the network and be connected, network can't be known the particular location of UE, only can know the general area at UE place, i.e. RA (routing area, route district)/LA (Location Area, lane place)/TA (tracking area, tracking area).Get into the coverage of HNB as MUE after; Take method such as power control to reduce in order to make HNB can perceive the entering of MUE and disturb, at first will solve and how make low power base station perceive the problem that in this base station signal coverage, has non-CSG member UE.Describe below.
Fig. 2 is the processing method implementing procedure sketch map of the non-CSG member UE of UE side, and is as shown in the figure, can comprise the steps: in the UE side
Step 201, UE confirm whether self is the CSG member UE of the affiliated low power base station of desire persistent district of current selection;
In the enforcement, the information of carrying the perception indication can adopt up RRC (Radio Resource Control, Radio Resource control) to connect and set up request message.
In the enforcement, can divide into the enforcement in the cell selecting process and in cell reselection process, describe below according to the state of UE.
1, in the cell selecting process, UE confirms that the desire persistent district of current selection is for selecting signal strength signal intensity sub-district best, that satisfy the S criterion on the frequency;
UE confirms according to this system information of subdistricts that the desire persistent district from current selection reads whether self is CSG member UE.
In the enforcement, after UE sends the information of carrying the perception indication to this low power base station, can further include:
UE continues to select other sub-districts of satisfying the S criterion to carry out access attempts.
In the enforcement, UE after receiving limit to surpass predetermined threshold value, sends the information of carrying the perception indication confirming behind the non-CSG member UE as this low power base station to this low power base station.
2, in cell reselection process, UE confirms that the desire persistent district of current selection is for selecting the best sub-district of highest ranked signal strength signal intensity on the frequency;
UE confirms according to this system information of subdistricts that the desire persistent district from current selection reads whether self is CSG member UE.
In the enforcement, UE after receiving limit to surpass predetermined threshold value, sends the information of carrying the perception indication confirming behind the non-CSG member UE as this low power base station to this low power base station.
In the practical implementation, in cell selecting process and cell reselection process, after realizing receiving limit to surpass predetermined threshold value when low power base station is sent the information of carrying the perception indication; Can a timer be set at UE; As MUE because the CSG ID of HNB broadcasting not self CSG white list former can not be normally resident, and after this limited resident state surpasses a period of time, also promptly surpass predetermined threshold value; UE can initiate RRC voluntarily and connect the process of setting up, and sends the perception indication to HNB.Wherein, " a period of time " can be the timer (informed by system broadcasts, perhaps provide in agreement) that the UE side is provided with, and perhaps realizes decision by UE.
In the practical implementation, if UE confirming behind non-CSG member UE as this low power base station, need to send the information that carry the perception indication to this low power base station immediately, then only need above-mentioned Preset Time threshold value to be set to " zero " and get final product.
In the enforcement, after UE sends the information of carrying the perception indication to this low power base station, further comprise:
UE continues to be chosen in the same best sub-district of highest ranked signal strength signal intensity frequently and carries out access attempts.
In the enforcement, UE is when confirming that from this system information of subdistricts that reads this low power base station is accepted to carry the information of perception indication, and UE just sends the information of carrying the perception indication to this low power base station.
This is that low power base station can be according to s own situation because not all low power base station all must receive this perception indication and adjust self power, and whether decision receives the perception indication, and whether carries out the subsequent power adjustment; And whether UE also can accept perception according to low power base station and indicate and determine whether to send the information of carrying perception indication.
Accordingly, after UE sent the information of carrying the perception indication to low power base station, the enforcement of low power base station side can be following:
Fig. 3 is the processing method implementing procedure sketch map of the non-CSG member UE of low power base station side, and is as shown in the figure, can comprise the steps:
In the enforcement, the information of carrying the perception indication can be that request message is set up in up RRC connection.
In the enforcement, cover the cavity, then after low power base station confirms in this base station signal coverage, to have non-member UE, can further include if UE gets into:
Low power base station reduces the interference to this UE.
Concrete, low power base station can adopt modes such as adjusting its power to reduce the interference to this MUE.
In the enforcement; Because the key of dealing with problems is to make the existence that low power base station can the non-CSG member UE of perception; Rather than it is carried out response process, therefore after low power base station confirms in this base station signal coverage, to have non-member UE, can further include:
Low power base station does not respond the information of carrying the perception indication that UE sends.
In the enforcement, can further include:
Low power base station notifies this base station whether to accept to carry the information of perception indication to the UE in this base station signal coverage in broadcast signaling.
In the enforcement, and do not require that all low power base station all must receive this perception indication and adjust self power, so low power base station can be according to s own situation, whether decision receives the perception indication, and whether carries out the subsequent power adjustment.
Be better to understand enforcement of the present invention, the enforcement that cooperates of UE and low power base station HNB is described with instance below.
Embodiment 1
Fig. 4 is the processing method implementing procedure sketch map of the non-CSG member UE of embodiment 1, and is as shown in the figure, can comprise the steps:
In the cell selecting process, owing to be not to select foundation with the system information, UE will select signal strength signal intensity sub-district best, that satisfy S criterion trial access on certain frequency.If this sub-district is HNB, UE read this system information of subdistricts and can know whether it is the member UE of this HNB this moment.If UE is not the member UE of this HNB, then this HNB is not the suitable cell (suitable cell) of UE.UE will attempt gravity treatment to other sub-districts as far as possible.If UE can gravity treatment, then carry out to other proper cell resident, if can't gravity treatment to other sub-districts, then will certainly stay HNB and be interfered.
Resident normally for this MUE can be obtained at MNB, HNB can adjust its power and reduce the interference to this MUE.Thereby, need MUE that the existence of self is informed to HNB and know in order to make HNB reduce interference by this MUE of perception.
Generally speaking, when UE, can't initiate general service and connect when state resides in certain sub-district with limited (not suitable/limited), only can send urgent call.In the technical scheme provided by the invention, then be to allow MUE to send up RRC connection to set up request message, and carry the perception indication of the existence of informing HNB self therein.
After HNB receives this indication, can need not, send to connect to UE and set up message, perhaps connect and set up failed message, only be used for power control to the indication of receiving and get final product according to existing RRC connection building process.
MUE also need not to wait for the answer message of HNB, if there is proper cell can directly carry out gravity treatment after sending and should indicating.
Embodiment 2
Fig. 5 is the processing method implementing procedure sketch map of the non-CSG member UE of embodiment 2, and is as shown in the figure, can comprise the steps:
Step 501, UE gravity treatment are to the CSG sub-district;
Step 502, read selected system information of subdistricts;
Step 503, judge that whether selected sub-district is the non-member HNB of UE, is then to change step 505 over to, otherwise changes step 504 over to;
Step 504, normally resident is initiated registration;
Step 505, limited resident is considered other reeligible candidate cells;
Step 506, judge and gravity treatment to have taken place in a period of time, be then to change step 507 over to, otherwise change step 508 over to other sub-districts;
Step 507, carry out resident to other suitable sub-districts;
Step 508, initiate to connect the process of setting up, with the existence notice HNB of self MUE.
In the cell reselection process, UE selects the best sub-district trial gravity treatment of highest ranked signal strength signal intensity on the high priority frequency.Generally speaking, when UE finds that the Target cell of gravity treatment is the non-member HNB of UE, UE will not consider that this sub-district is the candidate cell of gravity treatment, and on frequently, continue to consider other sub-districts.
In the technical scheme that the embodiment of the invention provides; UE considers that after carrying out the gravity treatment behavior gravity treatment is to other sub-districts on the frequency; If could gravity treatment would carry out to other proper cell resident, if can't gravity treatment to other sub-districts, then will certainly stay HNB and be interfered; Then will utilize RRC to connect to set up request message and carry the perception indication of informing that HNB self exists, and make the HNB can perception.
In the practical implementation; Can a timer be set at UE, as MUE because the CSGID of HNB broadcasting not self CSG white list former can not be normally resident, and after this limited resident state surpasses a period of time; UE initiates RRC voluntarily and connects the process of setting up, and sends the perception indication to HNB.Wherein, " a period of time " can be the timer (being informed that by system broadcasts perhaps agreement provides) that the UE side is provided with, and perhaps realizes decision by UE.
The HNB perception should indication after, can collect the measurement result that HUE reports through the HUE it under being sent measurement control order, thereby and carry out corresponding power and control, to reduce interference effect to MUE.
Embodiment 3:
In broadcast signaling, notify this base station whether to accept to carry the situation of the information of perception indication to low power base station to the UE in this base station signal coverage; Accordingly; UE is when confirming that from this system information of subdistricts that reads this low power base station is accepted to carry the information of perception indication, and UE sends the information of carrying the perception indication to this low power base station.
In the enforcement, can in the broadcast signaling of HNB, notify this HNB of UE whether to accept the perception indication and carry out power control.
In the present embodiment, do not require that all HNB must receive this perception indication adjustment self power, HNB can be according to s own situation, and whether decision receives the perception indication, and whether carries out the subsequent power adjustment.
For example, possible scene is following:
1, many as the user of HNB access, when the power adjustment may impact these users who has inserted, HNB can oneself not hope to accept perception indication adjustment power through other UE of broadcast announcement;
2, relatively idle or when not having the user to insert fully as HNB; Adjustment power can not impact large-scale user, and then HNB can broadcast it and can accept the perception indication, when MUE gets into the HNB scope, carries out corresponding power control; To reduce interference, keep the operate as normal of MUE to MUE.
The signaling aspect; Can be at certain system information block (SIB1 of system information; SIB2 or other SIB (System Information Block, system information block)) middle interpolation 1bit indication, when (perhaps being true) appears in this indication; Expression HNB can carry out power control when having MUE to get into its scope knowing.
HNB receive inform RRC that non-member MUE exists connect set up request message after, can send RRC not according to normal flow and connect and set up message or RRC and connect and set up failed message, send but reply signaling.The UE side also can not waited for this answer message, but when searching suitable cell, initiates the gravity treatment flow process.
Adopting HNB in the above-described embodiments is that example is because HNB is comparatively common also comparatively representative in low power base station; But; The technical scheme that the embodiment of the invention provides is equally applicable to other low power base station; HNB only is used to instruct specifically embodiment of the present invention how of those skilled in the art; But do not mean and only can use HNB base station, can combine demand in practice to be directed against corresponding low power base station in the implementation process and confirm corresponding execution mode.
