Embodiment 1

Fig. 1 illustrates the flow chart that alien frequencies adjacent area according to an embodiment of the invention determines method.As shown in figure 1, the method Main inclusion:

Step 110, cell to be optimized UE RAB release after, before RRC Connection Release, RNC issues different to this UE Frequency measuring control signal, carries the potential adjacent area of at least one this cell to be optimized in this different-frequency measure control signal;

Step 120, RNC receive the different-frequency measure reporting of the different-frequency measure result carrying potential adjacent area of this UE return;

Step 130, RNC determine alien frequencies adjacent area according to different-frequency measure reporting for this cell to be optimized.

The present embodiment is carried out that is to say, that RAB releases after the RAB release of UE completes and before RRC Connection Release It is not immediately performed RRC release after one-tenth, be set with therebetween the time period of 20s-60s, execute above-mentioned within this time period Alien frequencies adjacent area determines method, does not have any impact to the normal service switchover of UE, it is to avoid UMTS alien frequencies adjacent area leakage leads to Call drop and alien frequencies handoff failure, reduce cutting off rate and improve alien frequencies handover success rate.

Embodiment 2

Fig. 2 illustrates the flow chart that alien frequencies adjacent area according to another embodiment of the present invention determines method and measuring method.As Fig. 2 Shown, the method includes:

Step S210, RNC is that each cell to be optimized determines the potential Neighboring Cell List needing detection.

Specifically, before the RAB release of UE completes, or after characteristic startup, calculate each immediately to be optimized The potential adjacent area of UMTS cell.Potential adjacent area refers in the range of certain distance, is likely to occur in the range of such as three rank adjacent areas Switch does not configure cell, namely miss-configured neighboring cells.This potential adjacent area can configure according to the engineering parameter of cell to be optimized and RNC Data is calculated.If certain cell to be optimized does not have engineering parameter, then can calculate potential only with RNC configuration data Adjacent area.

As shown in figure 3, this step S210 specifically includes:

Step S2101, RNC calculates the potential adjacent area of the first candidate according to the engineering parameter of cell to be optimized.

In this step, latitude and longitude information in utilizing works parameter, centered on the position of cell to be optimized, search radius For default leakage distance threshold (English:Distance Threshold) in the range of all cells, and little by find Area is designated as the potential adjacent area of the first candidate of this cell to be optimized, gathers { A };If certain cell to be optimized does not have engineering parameter, The set { A } then corresponding to cell to be optimized is sky.

For this leakage distance threshold, determined according to the environment that base station is located in the present embodiment.Such as base station is located at During city, the distance between base station is relatively near, and such leakage distance threshold can be set to 1 kilometer, and base station is located at during suburb at a distance of relatively Far, what corresponding leakage distance threshold can be arranged is larger, such as 2 or 3 kilometers.

Step S2102, RNC calculates the potential adjacent area of the second candidate according to the RNC configuration data of cell to be optimized.

Specifically, second order adjacent area and three ranks of each cell to be optimized using the neighboring BS information in RNC configuration data, are searched Adjacent area, and the adjacent area finding is designated as the potential adjacent area of the second candidate of this cell to be optimized, gather { B };

In the present embodiment, for UMTS alien frequencies adjacent area, the lookup algorithm of second order adjacent area and three rank adjacent areas includes:

Single order adjacent area is the alien frequencies adjacent area of cell to be optimized;

Second order adjacent area is the alien frequencies adjacent area of the homogeneous-frequency adjacent-domain of cell to be optimized;

Three rank adjacent areas are the alien frequencies adjacent area of the homogeneous-frequency adjacent-domain of homogeneous-frequency adjacent-domain of cell to be optimized.

The set of single order adjacent area, second order adjacent area and three rank adjacent areas constitutes set { B }.

Step S2103, will gather { A } and set { B } merge.

Potential for first candidate adjacent area set { A } and the second candidate potential adjacent area set { B } are merged, that is, take union, It is designated as gathering { C }.

Step S2104, RNC carries out screening to the candidate potential adjacent area set after merging and generates potential Neighboring Cell List.

According to RNC configuration information, screen out matched adjacent zone from set { C }, remaining adjacent area constitutes this cell to be optimized Potential Neighboring Cell List.

Step 220, UE RAB discharge after the completion of, RNC to the UE in cell to be optimized issue different-frequency measure control letter Number, this different-frequency measure control signal at least carries corresponding to the scrambler scope of measurement and frequency model required for the potential adjacent area of UE Enclose;

In the present embodiment, with prior art UE RAB release after discharge immediately RRC be connected except that, The RAB release business of UE, including circuit switching(English:Circuit Switch, abbreviation:CS)Domain RAB release or packet are handed over Change(English:Packet Switch, abbreviation:PS)After RAB release in domain completes, RNC not release RRC connection immediately, but prolong The RRC that a long time period discharges UE again connects, and the time range of this prolongation can be 20s-60s, is preferably 30 in the present embodiment Second.The method that the present invention provides executed within the period of this prolongation.

RNC carries in different-frequency measure control signal scrambler scope and frequency point ranges so that UE can be according to this scrambler Scope and frequency point ranges carry out proprietary measurement to potential adjacent area accordingly.Every different-frequency measure control signal at most issues 32 and dives Scrambler and frequency in adjacent area.In addition every chip energy can also be carried in different-frequency measure control signal make an uproar with Carrier To Noise Power Density Acoustic ratio Ec/N0 and RSCP.The potential adjacent area carrying is chosen in the neighbor list from latent, as shown in figure 4, specifically, for each UE from the latent method selecting potential adjacent area is in the neighbor list:

Step 2201, RNC judge whether latent potential adjacent area in the neighbor list is not more than 32, are then execution steps 2206;Otherwise RNC enters road wheel according to the frequency range that priority of adjacent domain, each UE support to latent all potential adjacent area in the neighbor list Ask, select the potential adjacent area measuring for UE, concrete execution step 2202 for each UE;

Latent all potential adjacent area in the neighbor list is defined as the potential adjacent area of each UE by step 2206, RNC;

Step 2202, RNC are ranked up to latent all potential adjacent area in the neighbor list according to priority of adjacent domain;Adjacent area Priority refers to cell-of-origin(I.e. cell to be optimized)The far and near order of distance and potential adjacent area between, distance is nearer, and priority is higher, Sequence more forward it is also possible to referred to as neighbor cell configuration order.

Step 2203, RNC screen to the above-mentioned potential adjacent area after sequence according to the frequency range that each UE supports, will not support The potential adjacent area of the frequency range of this UE screens out, and obtains the potential adjacent area corresponding to each UE, if the number of potential adjacent area is more than 32 Individual, then at most carry 32 due in every different-frequency measure control signal, the different-frequency measure control signal therefore this UE being issued Can more than one.

Further, in the case that across PLMN switching switch of UE cuts out, can also include:

Step 2204, RNC can also enter advance to the above-mentioned potential adjacent area after frequency range screening according to the PLMN that this UE supports One step screening, is not supported that the potential adjacent area of the PLMN of this UE screens out;If across PLMN switching switch of UE is opened, do not execute This step.

Further, when UE is located at UMTS alien frequencies adjacent area, can also include:

Step 2205, RNC are screened always according to the covering priority of potential adjacent area, screen out cover priority be 0 latent In adjacent area.

This covering priority is to pre-set, and the priority of priority ratio other frequency of such as some frequencies is high, needs First send the higher frequency of priority to UE to measure, the covering priority of such cell is just higher.Cover priority Higher alien frequencies adjacent area is easier, and as covering, measurement object issues and UE is more easily switched to this cell.Priority is 0 representative Do not issue, cover priority be 1 cell be handed down to UE priority be higher than priority be 2 cell it is easier to conduct cover Lid measurement object issues, and UE is easier to be switched to and covers the cell that priority is 1.And, when sending measuring controls, if many Individual alien frequencies adjacent area is same frequency, then the priority of these alien frequencies adjacent areas is all processed by limit priority therein, works as alien frequencies When adjacent area quantity is more than 32, covering the low adjacent area of priority will not issue in measurement control list.

In aforementioned four condition, the frequency range that range information that priority of adjacent domain is based on, UE are supported asks to set up in UE RRC will carry when connection, the information acquisition that RNC is carried in being asked by RRC.Range information is by UE according to engineering parameter Latitude and longitude information in information is calculated, mobile national number(English:Mobile Country Code, abbreviation:MCC)+ move Dynamic network number(English:Mobile Network Code, abbreviation:MNC), i.e. PLMN, according to the configuration of engineering parameter and RNC Parameter can obtain.It is not limited to according to the order that aforementioned four condition is screened to latent potential adjacent area in the neighbor list Said sequence.

Because the frequency ability of each UE is different, frequency range that is supporting is different or affiliated PLMN is variant, therefore RNC is each The potential adjacent area that UE selects is not necessarily identical.

Additionally, needing to record the order currently chosen after selecting potential adjacent area to be measured for certain UE, next When secondary selection, directly a potential adjacent area after this order starts poll.When remaining adjacent area is less than 32, then from Head starts poll, i.e. circulation issues different-frequency measure control signal.

Step 230, UE according to the different-frequency measure control signal receiving, to the potential neighbour in this different-frequency measure control signal Area carries out different-frequency measure, and different-frequency measure result is carried in different-frequency measure reporting(English:Measurement Report)In Return to RNC.

Specifically, after UE receives different-frequency measure control signal, to the scrambler of each potential adjacent area, frequency, Ec/N0 with And RSCP is detected.

Additionally, before or after step 230 or synchronously, this method can also include:

Step 240, record the latent number of times that each potential adjacent area is issued in the neighbor list in RNC daily record.

Specifically, RNC increases the chunk that a potential adjacent area issues in RNC daily record, to each potential adjacent area by under The number of times sent out is counted.

Step 250, RNC are that each cell to be optimized selects alien frequencies adjacent area according to the different-frequency measure reporting receiving.

Specifically, RNC or SON master issues number of times, signal quality, scrambler, frequency, Ec/N0 according to potential adjacent area And RSCP potential adjacent area is ranked up, and it is set to respectively with reference to the spare bits in the alien frequencies Neighboring Cell List of this cell to be optimized Cell to be optimized selects alien frequencies adjacent area, and for example, the spare bits in the alien frequencies Neighboring Cell List of certain cell to be optimized are set to 5, then RNC is This cell selected and sorted to be optimized is the potential adjacent area of first 5 as alien frequencies adjacent area.

During step 210-250 determines alien frequencies adjacent area for cell to be optimized, if this cell to be optimized has UE Initiate calling, or called, then suspend current different-frequency measure, RNC starts normal RAB request and connects, and in end of calling Afterwards, the step recalculating the different-frequency measure time of this prolongation and restarting different-frequency measure.

And, in above-mentioned steps, if currently cell to be optimized has a UE to complete RAB release, can allow preferential This UE is allowed to measure potential adjacent area.

It is possible to release RRC connects after RNC selects alien frequencies adjacent area for cell to be optimized, or when default Between after section timing terminates, release RRC connects.
