embodiment 1
Fig. 1 illustrates the flow chart that method is determined in alien frequencies adjacent area according to an embodiment of the invention.As shown in Figure 1, the method mainly comprises:
The present embodiment carries out after the RAB of UE has discharged He before RRC Connection Release, that is to say, after RAB has discharged, not carrying out immediately RRC discharges, between the two, be set with the time period of 20s-60s, within this time period, carry out above-mentioned alien frequencies adjacent area and determine method, the normal service switchover of UE, without any impact, has been avoided UMTS alien frequencies adjacent area to leak and joined call drop and the alien frequencies handoff failure causing, reduced cutting off rate and improved alien frequencies handover success rate.
embodiment 2
Fig. 2 illustrates the flow chart that method and method of measurement are determined in alien frequencies adjacent area according to another embodiment of the present invention.As shown in Figure 2, the method comprises:
Step S210, RNC are that the potential Neighboring Cell List that needs detection is determined in each community to be optimized.
Particularly, before the RAB of UE has discharged, or after characteristic startup, calculate immediately the potential adjacent area of each UMTS community to be optimized.Potential adjacent area refers within the scope of certain distance, such as the ，Ye Ji miss-configured neighboring cells, not allocating cell that likely switch within the scope of three adjacent areas, rank.This potential adjacent area can calculate according to the engineering parameter of community to be optimized and RNC configuration data.If certain community to be optimized does not have engineering parameter, can only adopt so RNC configuration data to calculate potential adjacent area.
As shown in Figure 3, this step S210 specifically comprises:
Step S2101, RNC calculate the first potential adjacent area of candidate according to the engineering parameter of community to be optimized.
In this step, utilize the latitude and longitude information in engineering parameter, centered by the position of community to be optimized, searching radius is that distance threshold (English: Distance Threshold) all communities in scope is joined in default leakage, and the community finding is designated as to the first potential adjacent area of candidate of this community to be optimized, set { A}; If certain community to be optimized does not have engineering parameter, corresponding to the set of community to be optimized, { A} is empty.
For this leakage, join distance threshold, the environment being positioned at according to base station in the present embodiment is determined.Such as base station close together between base station when the city, leak like this and join distance threshold and can be made as 1 kilometer, apart from each other when base station is positioned at suburb, corresponding leakage joined larger that distance threshold can arrange, for example 2 or 3 kilometers.
Step S2102, RNC calculate the second potential adjacent area of candidate according to the RNC configuration data of community to be optimized.
Particularly, utilize the neighboring BS information in RNC configuration data, search second order adjacent area and three adjacent areas, rank of each community to be optimized, and the adjacent area finding is designated as to the second potential adjacent area of candidate of this community to be optimized, set { B};
In the present embodiment, for UMTS alien frequencies adjacent area, the algorithm of searching of second order adjacent area and three adjacent areas, rank comprises:
Single order adjacent area is the alien frequencies adjacent area of community to be optimized;
Second order adjacent area is the alien frequencies adjacent area of the homogeneous-frequency adjacent-domain of community to be optimized;
The alien frequencies adjacent area of the homogeneous-frequency adjacent-domain of the homogeneous-frequency adjacent-domain that three adjacent area, rank are community to be optimized.
The set of single order adjacent area, adjacent area, ,Ji San rank, second order adjacent area forms set { B}.
Step S2103, will gather that { { B} merges for A} and set.
By first candidate's potential adjacent area set, { { B} merges, and gets union, is designated as set { C} in A} and the second candidate potential adjacent area set.
Candidate's potential adjacent area set after step S2104, RNC are combined is screened and is generated potential Neighboring Cell List.
According to RNC configuration information, from set, { C}, screen out matched adjacent zone, remaining adjacent area has formed the potential Neighboring Cell List of this community to be optimized.
In the present embodiment, with in prior art, after the RAB of UE discharges, discharge immediately RRC and be connected difference and be, RAB at UE discharges business, comprise circuit switching (English: Circuit Switch, abbreviation: CS) territory RAB discharges or packet switching (English: Packet Switch, abbreviation: PS) after territory RAB has discharged, RNC does not discharge immediately RRC and connects, but extend the RRC that a time period discharges UE again, connect, the time range of this prolongation can be 20s-60s, is preferably 30 seconds in the present embodiment.Method provided by the invention is carried out within the period of this prolongation.
RNC is carried at scrambler scope and frequency point ranges in different-frequency measure control signal, makes UE to corresponding potential adjacent area, to carry out proprietary measurement according to this scrambler scope and frequency point ranges.Every different-frequency measure control signal issues at most scrambler and the frequency of 32 potential adjacent areas.In addition in different-frequency measure control signal, can also carry every chip energy and Carrier To Noise Power Density noise ratio Ec/N0 and RSCP.The potential adjacent area of carrying is chosen from potential Neighboring Cell List, and as shown in Figure 4, particularly, the method for selecting potential adjacent area for each UE from potential Neighboring Cell List is:
The frequency range that step 2203, RNC support according to each UE is screened the above-mentioned potential adjacent area after sorting, to not support the potential adjacent area of the frequency range of this UE to screen out, obtain the potential adjacent area corresponding to each UE, if the number of potential adjacent area is more than 32,, owing to carrying at most 32 in every different-frequency measure control signal, the different-frequency measure control signal therefore this UE being issued is understood more than one.
Further, in the situation that closing across PLMN diverter switch of UE can also comprise:
Further screen above-mentioned potential adjacent area after the PLMN that step 2204, RNC can also support according to this UE screens frequency range, will not support the potential adjacent area of the PLMN of this UE to screen out; If UE opens across PLMN diverter switch, do not carry out this step.
Further, when UE is positioned at UMTS alien frequencies adjacent area, can also comprise:
This priority covering level is for setting in advance, and for example the priority of other frequency of priority ratio of some frequency is high, needs first to UE, to send the higher frequency of priority and measures, and the priority covering level of such community is just higher.More easily as covering, measuring object issues the higher alien frequencies adjacent area of priority covering level and UE is more easily switched to this community.Priority is that 0 representative does not issue, and the community that the priority of UE is 2 higher than priority is handed down in the community that priority covering level is 1, more easily as covering measuring object, issue, and UE to be more easily switched to priority covering level be 1 community.And, when sending measuring is controlled, if a plurality of alien frequencies adjacent area is same frequency, the priority of these alien frequencies adjacent areas is all processed by limit priority wherein, when alien frequencies adjacent area quantity is greater than 32, the adjacent area that priority covering level is low can not controlled in list and issue in measurement.
In above-mentioned four conditions, priority of adjacent domain based on range information, frequency range that UE supports in UE request, set up when RRC connects and will carry, the information acquisition that RNC carries in asking by RRC.Range information is calculated according to the latitude and longitude information in engineering parameter information by UE, mobile national number (English: Mobile Country Code, abbreviation: MCC)+mobile network code (English: Mobile Network Code, abbreviation: MNC), be PLMN, according to the configuration parameter of engineering parameter and RNC, can obtain.The order of the potential adjacent area in potential Neighboring Cell List being screened according to above-mentioned four conditions is not limited to said sequence.
Frequency ranges different due to the frequency ability of each UE, that support are different or affiliated PLMN are variant, thus RNC for the potential adjacent area of each UE selection not necessarily identical.
In addition, after selecting potential adjacent area to be measured for certain UE, need to record the current order of choosing, when selecting, directly from a potential adjacent area after this order, start poll next time.When 32 of remaining adjacent area less thaies, then the poll that starts anew, i.e. circulation issues different-frequency measure control signal.
Particularly, after UE receives different-frequency measure control signal, the scrambler of each potential adjacent area, frequency, Ec/N0 and RSCP are detected.
In addition, before or after step 230 or synchronously, this method can also comprise:
Particularly, RNC increases the block of information that a potential adjacent area issues in RNC daily record, and the number of times that each potential adjacent area is issued is added up.
Particularly, RNC or SON master sort to potential adjacent area according to issue number of times, signal quality, scrambler, frequency, Ec/N0 and the RSCP of potential adjacent area, and be set to each selection alien frequencies adjacent area, community to be optimized in conjunction with the spare bits in the alien frequencies Neighboring Cell List of this community to be optimized, for example, spare bits in the alien frequencies Neighboring Cell List of certain community to be optimized is set to 5, and RNC is that this community to be optimized selects potential adjacent area that sequence is first 5 as alien frequencies adjacent area.
At determining in the process of alien frequencies adjacent area for community to be optimized of step 210-250, if this community to be optimized has UE to make a call, or called, suspend current different-frequency measure, RNC starts normal RAB request and connects, and after end of calling, recalculate the different-frequency measure time of this prolongation and restart the step of different-frequency measure.
And, in above-mentioned steps, if current community to be optimized has a UE to complete RAB release, can allow and preferentially allow this UE measure potential adjacent area.
RNC is after alien frequencies adjacent area is selected in community to be optimized, just can discharge RRC and connect, or after waiting until that default time period timing finishes, discharge RRC and connect.
