Method embodiment one
According to the embodiment of the invention, provide a kind of CSG cell selecting method.This method is used for handling under the user selects to reside in the situation of CSG sub-district.
Fig. 2 shows the flow process according to the CSG cell selecting method of the inventive method embodiment one, as shown in Figure 2, may further comprise the steps (step S202 is to step S204) according to the CSG cell selecting method of the inventive method embodiment one:
Step S202, the CSG sub-district that the UE search is available;
Step S204, if UE judges that the CSG sub-district search is preassigned CSG sub-district, and the signal quality of the CSG sub-district that searches satisfies pre-provisioning request, is persistent district with the CSG cell selecting that searches then.Preferably, pre-provisioning request can be minimum speech quality requirement.
Describe the process of above-mentioned processing below in detail.
If there is the CSG white list of non-NULL among the UE, in the invention process process, provide the cell selecting manual mode during cell selecting, the sub-district that can provide two types is selected for the user, and a kind of is the CSG sub-district, and a kind of is non-CSG sub-district.
Select to reside under the situation of CSG sub-district the user
Particularly, in step S204, judge that whether the CSG sub-district search is that the operation of preassigned CSG sub-district can specifically comprise: if can in the white list (or being called the CSG white list) of UE, find the identical cell ID of cell ID with the CSG sub-district that searches, judge that then the CSG sub-district that searches is preassigned CSG sub-district, wherein, white list is used to specify the CSG sub-district that this UE can use, and wherein stores the cell ID of at least one preassigned CSG sub-district in advance.
When the CSG sub-district that searches is sub-district in the CSG white list of UE, and the signal quality of this CSG sub-district that searches satisfies pre-provisioning request, then select to reside under the situation of CSG sub-district the user, and be persistent district with the CSG cell selecting that searches.
Wherein, the signal quality of CSG sub-district satisfies pre-provisioning request and can judge according to the signal strength signal intensity of this sub-district.
In addition, carry out above-mentioned steps S202 to the process of step S204, if judging the CSG sub-district search is not that the signal quality of preassigned CSG sub-district and/or the CSG sub-district that searches does not satisfy predetermined the requirement (promptly in the white list, minimum conversation requirement, also can be called the S standard), the available non-CSG sub-district of UE search then, the non-CSG cell selecting that signal quality is satisfied pre-provisioning request is a persistent district, and information that will this non-CSG sub-district reports Non-Access Stratum.
Select to reside under the situation of non-CSG sub-district the user
In this case, UE is according to the cell selecting process of routine, and is resident to non-CSG sub-district, because the CSG sub-district is to control the particular cell that UE inserts flexibly by operator, therefore, in this case, if UE is resident to the failure of non-CSG sub-district, then UE can be resident to any sub-district.
The method that provides by present embodiment, UE is in the available CSG sub-district that searches, select an appointment in advance and the satisfactory CSG of signal quality sub-district as persistent district, make UE can carry out effective CSG cell selecting, be convenient to the application of CSG business, filled up the blank in the correlation technique.
Based on above description, below the concrete process of implementing of present embodiment is described.
In the concrete process of using, if UE does not open CSG business (that is, the CSG white list of UE is empty), then can carry out cell selecting (gravity treatment) according to process as shown in Figure 1, resident to proper cell.In the process of carrying out cell selecting, if the sub-district that UE searches is the CSG sub-district, can not reside at this CSG sub-district, search for and select other suitable cell again.
If UE has opened the CSG business (promptly, CSG white list non-NULL, include the cell ID of designated cell in advance in this white list), then UE is in the cell selecting process, can select resident as required to the CSG sub-district, perhaps select the resident non-CSG sub-district of arriving, and, can carry out cell selecting with manual selection or the mode of selecting automatically.Be that example describes with manual selection course below:
Step 1, whether selection is resident to the CSG sub-district, if resident to the CSG sub-district, handle and proceeds to step 2, if resident to non-CSG sub-district, processing proceeding to step 7;
Step 2, the CSG sub-district that the UE search is available if can search the CSG sub-district, handles proceeding to step 3, otherwise, handle proceeding to step 7; Step 2 is corresponding to above-mentioned steps S202;
Step 3 judges whether this CSG sub-district is the sub-district of appointment in the CSG white list, if the CSG sub-district of appointment is then handled and proceeded to step 4; If not the CSG sub-district of appointment, then handle and proceed to step 7;
Step 5, UE judges whether the signal quality of this sub-district satisfies the S standard,, judges whether the signal quality of this sub-district satisfies minimum conversation requirement that is, if satisfy, handles proceeding to step 6, otherwise, handle changing step 7 over to;
Step 7 is searched for available non-CSG sub-district;
Step 8 is measured the signal quality of this non-CSG sub-district;
Step 9 judges whether the signal quality of this non-CSG sub-district satisfies the S standard, proceeds to step 10 if satisfy to handle, otherwise, handle changing step 11 over to;
Step 10 should non-CSG cell selecting be a persistent district;
If in step 1, select to reside in the CSG sub-district, but do not search the CSG sub-district in the step 2, or the CSG sub-district that searches in the step 3 is not the CSG sub-district of appointment, or judge in the step 5 that the signal quality that searches the sub-district does not satisfy the S standard, thus it is resident to the CSG sub-district to cause UE not have, and reside in non-CSG sub-district, in this case, UE is resident when the non-CSG sub-district, needs the notice Non-Access Stratum, and the information of resident non-CSG sub-district is sent to Non-Access Stratum.
Step 11, the selection arbitrary cells is a persistent district.
Automatically select the process of CSG sub-district can comprise that above-mentioned step 2 to step 11, repeats no more here.
By the processing procedure of above-mentioned steps 1 to step 11, UE can select resident to CSG sub-district or non-CSG sub-district neatly, and, when selecting the failure of CSG sub-district, select non-CSG sub-district as persistent district automatically, perhaps when selecting the failure of non-CSG sub-district, the selection arbitrary cells is a persistent district.
Device embodiment one
According to the embodiment of the invention, a kind of CSG cell selecting apparatus is provided, preferably, the CSG cell selecting method that can on this device, provide among the implementation method embodiment one.
Fig. 3 shows the structure according to the CSG cell selecting apparatus of apparatus of the present invention embodiment one, as shown in Figure 3, the CSG cell selecting apparatus according to apparatus of the present invention embodiment one comprises search module 1, first judge module 3, second judge module 5, selects module 7.The following describes the function of above-mentioned module.

Method embodiment two
According to this method embodiment, provide a kind of CSG residence reselecting.
Before carrying out the CSG residence reselecting, present embodiment also provides UE to carry out two class trigger conditions of CSG sub-district reselection evaluation, this two classes condition is as follows: the first kind, the UE internal trigger specifically can include but not limited to: the current area signal quality does not meet the demands, predetermined cell gravity treatment periodicity timer expiry; Second class is when the CSG information in the system broadcast information changes.
Fig. 4 shows the flow process according to the CSG residence reselecting of the inventive method embodiment two, as shown in Figure 4, may further comprise the steps (step S402 is to step S404) according to the CSG residence reselecting of the inventive method embodiment two:
Step S402 starts under the situation of sub-district gravity treatment the CSG sub-district that the UE search is available at UE;
Step S404, if UE has surpassed the scheduled time at the residence time of current persistent district, and the CSG sub-district that searches is preassigned CSG sub-district, and the signal quality of CSG sub-district satisfies pre-provisioning request, and it is new persistent district that search is arrived the CSG cell selecting.Preferably, the scheduled time minimumly can be 1 second.
Describe the process of above-mentioned processing below in detail.
After searching available CSG sub-district, the process that UE carries out the sub-district gravity treatment can be divided into following four kinds of situations:
Situation one, if current persistent district is non-CSG sub-district, and the signal quality of the CSG sub-district that searches satisfies the S standard, with the CSG sub-district that searches as new persistent district;
Situation two, if current persistent district is the CSG sub-district, current persistent district is a co-frequency cell with the CSG sub-district that searches, and according to the R standard, the R index of the CSG sub-district that searches is higher than the R index of current persistent district, with the CSG sub-district that searches as new persistent district;
Situation three, if current persistent district is the CSG sub-district, current persistent district and the CSG sub-district that searches are alien-frequency district, and the priority of the CSG sub-district that searches is higher than the priority of current persistent district, with the CSG sub-district that searches as new persistent district.
Situation four, if current persistent district is the CSG sub-district, and the satisfied predetermined minimum threshold of the signal quality of current persistent district, the then available sub-district of UE search.If search non-CSG sub-district, and this non-CSG sub-district satisfies cell selecting S standard, and the UE gravity treatment is to this non-CSG sub-district, and information that will this non-CSG sub-district reports Non-Access Stratum.
In addition, in above-mentioned process of carrying out the sub-district gravity treatment, if judge that the CSG sub-district that searches is not preassigned CSG sub-district, UE can not select or gravity treatment to this sub-district.When CSG relevant information in UE or the system information changed, Non-Access Stratum need notify UE to upgrade CSG sub-district candidate list information.
The method that provides by present embodiment, current area resident the UE of the scheduled time when needing re-selecting cell, in the available CSG sub-district that searches, select an appointment in advance and the satisfactory CSG of signal quality sub-district as persistent district, make UE can carry out effective CSG cell selecting.
Based on above description, below the concrete process of implementing of present embodiment is described.
As periodically triggering the gravity treatment of CSG sub-district, perhaps the CSG relevant information has taken place under the situation of change in the system information, UE triggering cell reselection evaluation process in the UE internal trigger.
If CSG white list non-NULL among the UE, after triggering CSG sub-district reselection evaluation process under these conditions, same frequency, different-frequency measure rule in the time of can be with reference to common sub-district reselection evaluation process be judged, measure rule if satisfy, and then carry out with frequently, alien-frequency district measures.According to UE current service cell and the cell conditions that measures, the gravity treatment of CSG sub-district is divided into following three kinds of modes:
Mode one, from non-CSG sub-district to the CSG sub-district: if the current persistent district of UE is non-CSG sub-district, cell selecting S standard is satisfied in the CSG sub-district that searches, and UE residence time on current persistent district surpasses 1 second, and gravity treatment is to the CSG sub-district; Mode one can be corresponding and above-mentioned situation one;
Mode two CSG minizone gravity treatments: if the current persistent district of UE is the CSG sub-district, cell selecting S standard is satisfied in the CSG sub-district that searches, and when UE surpasses 1 second at former CSG sub-district residence time, can handle according to the mode of co-frequency cell gravity treatment or alien-frequency district gravity treatment:
Co-frequency cell: if current persistent district is a co-frequency cell with the sub-district that searches, then according to the R standard of co-frequency cell gravity treatment, if the CSG sub-district that searches R value in the gravity treatment time is higher than the R value of former CSG sub-district, gravity treatment is to the CSG sub-district that searches; Gravity treatment can be corresponding and above-mentioned situation two between co-frequency cell;
Alien-frequency district:,, determine whether gravity treatment is to new CSG sub-district according to alien-frequency district priority in the E-UTRAN if current persistent district is an alien-frequency district with the sub-district that searches; Gravity treatment can be corresponding to above-mentioned situation three between alien-frequency district;
Mode three, if current persistent district is the CSG sub-district, and current resident CSG cell signal quality do not meet the demands, and (this threshold value can be specified in system message to be lower than default threshold value, also can be reduced to the S standard that does not satisfy cell selecting), UE can gravity treatment arrive non-CSG sub-district.At this moment, if the non-CSG cell signal that searches satisfies cell selecting S standard, then gravity treatment is to this non-CSG sub-district, and information that will this non-CSG sub-district reports Non-Access Stratum.
UE in cell reselection process, if the ID of the CSG sub-district that searches not in the CSG of UE white list, then UE can not reside in this CSG sub-district.When CSG relevant information in UE or the system information changed, Non-Access Stratum need notify UE to upgrade CSG sub-district candidate list information.
By above-mentioned processing, UE can carry out effectively, the CSG sub-district is again flexibly.
