Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, the Time Division-Synchronous Code Division Multiple Access access) GSM (Global System for Mobile Communication, global system for mobile communications) the adjacent area adding method and the equipment of sub-district.
Background technology
GSM (Global System for Mobile Communication, global mobile communication) is second generation mobile communication system (2G), the data service of this system's support voice and low rate, GSM network a lot of countries commercialization at present in the whole world, network coverage is wider.
TD-SCDMA (Time Division-Synchronous Code Division Multiple Access: Time Division-Synchronous Code Division Multiple Access inserts) is 3-G (Generation Three mobile communication system) (3G), with respect to the 2G system, higher service transmission rate can be provided, for the user provides abundanter service, this system has reached commercial level and has been widely used at present.
Because said GSM and TD-SCDMA network are network coexisted with TD-SCDMA network and GSM when the TD-SCDMA networking.In this case, can be in conjunction with the service rate of TD-SCDMA network the advantages such as wide coverage of advantage such as high and service-enriched and GSM network, for the user provides better mobile communication service.This just requires the network equipment and terminal to be supported in switching between TD-SCDMA and the GSM sub-district, and the terminal that can satisfy this requirement is called TD-SCDMA/GSM bimodulus (DualMode) terminal.
In existing TD-SCDMA network, opening the stage of network, dispose the GSM adjacent area of each TD-SCDMA sub-district according to TD-SCDMA cell information and GSM cell information, specifically obtain TD-SCDMA cell information and GSM cell information according to the network planning of TD-SCDMA network itself and the planning information of GSM, as obtaining the positional information of sub-district, some wireless parameters of sub-district are such as coverage condition of frequency and sub-district etc.
In the network opening stage, when being each TD-SCDMA cell configuration GSM adjacent area according to TD-SCDMA cell information and GSM cell information, because the radio configuration difference of each sub-district of diverse location need be carried out the data input of the GSM adjacent area of each TD-SCDMA sub-district respectively, configuration is complicated.
In the O﹠M stage of network, because geographical environment changes or GSM network optimization meeting causes the GSM neighboring BS information to change, such as the parameters such as frequency point information of revising the GSM sub-district owing to dilatation, at this moment upgrade the GSM neighbor cell configuration of TD-SCDMA sub-district with regard to the knowing this variation of the needs moment for the TD-SCDMA network.At present, the TD-SCDMA network obtains the method that the GSM cell information changes and realizes by irregular artificial drive test, finds untimelyly, and manually drive test is also more consuming time.
Insert in the TD-SCDMA network development process in user terminal UE start, the TD-SCDMA Serving cell sends to UE with GSM neighbor cell configuration situation.After UE is linked into the TD-SCDMA network, may be in constantly in the moving process, when UE was in the poor environment of covering, the measurement report that network side reports according to UE can determine that the covering intensity of UE present position does not meet the demands, and sent signaling message notice UE to UE; After UE received signaling message, when determining that according to GSM neighbor cell configuration situation the TD-SCDMA Serving cell does not dispose the GSM adjacent area, occurrence cause was the cell update Cell Update process of RLF (Radio Link Failure, Radio Link Failure); When UE determines that according to GSM neighbor cell configuration situation the TD-SCDMA Serving cell disposes the GSM adjacent area, according to the GSM neighboring BS information that disposes radio frequency is switched to the GSM frequency from the TD-SCDMA frequency GSM adjacent area is measured, metrical information is reported network side; Whether network side switches to the GSM adjacent area according to metrical information indication UE; When switched the GSM adjacent area, UE switched to the GSM adjacent area from current TD-SCDMA Serving cell at network side indication UE; Not when switch the GSM adjacent area, the UE occurrence cause is the cell update Cell Update message process of RLF at network side indication UE.
Because can not in time obtain the GSM cell information in the existing method changes, therefore the GSM adjacent area and the actual GSM cell information of the configuration of TD-SCDMA Serving cell are not inconsistent, perhaps no longer satisfy the GSM neighbor cell configuration of TD-SCDMA Serving cell configuration, the GSM adjacent area and the quilt leakage that perhaps have new GSM sub-district to can be used as the TD-SCDMA Serving cell add, and influence the interoperability performance of TD-SCDMA and GSM network.Under the situation about being added by leakage in the GSM adjacent area of TD-SCDMA Serving cell, UE can occurrence cause be the cell updating course of RLF still, and this cell updating course may also may be failed in success under the poor environment of TD-SCDMA covering, can cause the UE call drop when failure, influences the user and uses.

Embodiment
Illustrate in greater detail below in conjunction with the GSM adjacent area adding method and the equipment of drawings and Examples the TD-SCDMA sub-district of the present invention's proposition.
In embodiments of the invention, the GSM adjacent area adding method of a kind of TD-SCDMA sub-district is provided, as shown in Figure 1, this method comprises:
Step S101 obtains the pilot frequency intensity value of the TD-SCDMA Serving cell of the UE that Radio Link Failure RLF (Radio Link Failure) takes place;
As previously mentioned, insert in the TD-SCDMA network development process in user terminal UE start, the TD-SCDMA Serving cell sends to UE with GSM neighbor cell configuration situation.After UE is linked into the TD-SCDMA network, may be in constantly in the moving process, when UE is in the poor environment of covering, think relatively poor as TD-SCDMA network coverage pilot tone less than-90dBm, the measurement report that network side reports according to UE can determine that the covering intensity of UE present position does not meet the demands, and sends signaling message notice UE to UE; After UE received signaling message, when determining that according to GSM neighbor cell configuration situation the TD-SCDMA Serving cell does not dispose the GSM adjacent area, occurrence cause was the cell update Cell Update process of RLF (Radio Link Failure, Radio Link Failure); When UE determines that according to GSM neighbor cell configuration situation the TD-SCDMA Serving cell disposes the GSM adjacent area, according to the GSM neighboring BS information that disposes radio frequency being switched to the GSM frequency from the TD-SCDMA frequency measures the GSM adjacent area, some concrete measurements comprise that pilot frequency intensity is GSM carrier wave RSSI (Received Signal Strength Indicator, the indication of received signal intensity) or the like, metrical information is reported network side; Whether network side switches to the GSM adjacent area according to metrical information indication UE; When switched the GSM adjacent area, UE switched to the GSM adjacent area from current TD-SCDMA Serving cell at network side indication UE; Not when switch the GSM adjacent area, the UE occurrence cause is the cell update Cell Update message process of RLF at network side indication UE.
As seen, when UE is in the poor environment of covering, do not disposing the GSM adjacent area, or disposing the GSM adjacent area when the satisfied switching of GSM nearby region measurement requires, Radio Link Failure RLF takes place in UE, thus the triggering cell renewal process.
Step S102 according to the comparison of described pilot frequency intensity value and setting threshold, determines that the TD-SCDMA Serving cell leaks when adding the GSM adjacent area, obtains up-to-date TD-SCDMA cell information and GSM cell information;
Pilot signal is the Direct Sequence Spread Spectrum Signal that cell base station is launched non-modulated continuously, it makes UE can obtain the forward direction CDMA channel time limit, the correlation demodulation phase reference is provided, and for each base station provides signal strength signal intensity relatively, UE can determine when and switch, so the pilot frequency intensity value of TD-SCDMA Serving cell is represented the covering intensity of this TD-SCDMA Serving cell.After the pilot frequency intensity value of the TD-SCDMA sub-district of the UE that RLF to take place, in this enforcement this pilot frequency intensity value and setting threshold (P+ δ) are compared, wherein P represents an absolute strength value, δ then represents a surplus, if this value is less than this thresholding, it is relatively poor just to think that UE present located position TD-SCDMA covers, being judged as herein, UE should switch to certain GSM sub-district, and because the leakage of TD-SCDMA Serving cell adds the GSM adjacent area, be currently not have the GSM adjacent area that to switch and do not switch, cause the user in the TD-SCDMA network, RLF to take place and triggering cell is upgraded Cell Update process.
If the pilot frequency intensity value of TD-SCDMA Serving cell is not less than above-mentioned setting threshold in the present embodiment, determine that then the TD-SCDMA Serving cell does not have leakage to add the GSM adjacent area, but because RLF takes place in other reasons.
When definite TD-SCDMA Serving cell leakage adds the GSM adjacent area, specifically obtain up-to-date TD-SCDMA cell information and GSM cell information in the present embodiment by the most recent layout information table that imports TD-SCDMA sub-district and GSM network cell.
Step S103 according to described up-to-date TD-SCDMA cell information and GSM cell information, redefines the GSM adjacent area of described TD-SCDMA Serving cell;
Specifically can determine the GSM adjacent area of above-mentioned TD-SCDMA Serving cell according to some principles that have the GSM adjacent area of determining the TD-SCDMA sub-district now.
Step S104 adds the GSM adjacent area that redefines to described TD-SCDMA Serving cell.
Like this, insert in the TD-SCDMA network development process in UE start next time, the TD-SCDMA Serving cell sends to UE with GSM neighbor cell configuration situation.After UE is linked into the TD-SCDMA network, be in when covering in the poor environment at UE, can realize switching to the GSM adjacent area of new configuration, owing to be up-to-date and the actual GSM cell configuration that conforms to, can successfully realize switching to the GSM adjacent area.Utilize the present invention can find automatically at network side that the GSM adjacent area of TD-SCDMA sub-district is leaked and join problem, and the automatic interpolation of carrying out the GSM adjacent area realizes self-optimization function, optimize the TD-SCDMA network quality, improve the interoperability of TD-SCDMA network and GSM.
Because TD-SCDMA manufacturer can't obtain the situation that actual business terminal is in the GSM network, therefore, can only obtain some information of UE (such as the sub-district ID that inserts by the cell update Cell Update message that UE sends to UTRAN (land radio access web), the pilot frequency information of sub-district, the sign of UE, reason of cell update or the like).Based on this analysis result, can obtain some pilot frequency informations that RLF takes place and carry out whether because of adding the judgement that RLF takes place in the GSM adjacent area, during concrete enforcement, obtain the pilot frequency intensity value of the TD-SCDMA Serving cell of the UE that RLF takes place at step S101, can adopt in following three kinds of modes any:
1) 6A event report and/or the 5A event report that before cell update, reports according to the UE that RLF takes place, obtain the pilot frequency intensity value of TD-SCDMA Serving cell, wherein the 6A event report is that the transmitted power of UE is higher than the measurement report that reports when setting thresholding, it is the measurement report of the additional pilots of the 6A that stipulates in the standard, the 5A event report is the measurement report that the bLock error rate BLER (Block Error Ratio) of UE transmission data reports during greater than set point, the i.e. measurement report of the additional pilots of the 5A that stipulates in the standard.The pilot frequency intensity value of the residing Serving cell of UE and all adjacent sub-districts before this two classes measurement report all can reporting cell upgrades.Therefore, can from this two classes measurement report, obtain to take place the pilot frequency intensity value of TD-SCDMA Serving cell of the UE of RLF.
2) the cell update message that reports in cell updating course according to the UE that RLF takes place is obtained the pilot frequency intensity value of described TD-SCDMA Serving cell.
Obtain the Cell Update message that UE reports from network side cell updating course, therefrom obtain the TD-SCDMA Serving cell ID number, and know the pilot frequency intensity value of this TD-SCDMA Serving cell, need to prove, the pilot frequency intensity value of TD-SCDMA Serving cell may be to make UE that the TD-SCDMA Serving cell of RLF take place, also may be that UE finishes current TD-SCDMA Serving cell of communicating by letter behind the cell update, but can use the step that pilot frequency intensity value that this pilot value comes as the TD-SCDMA Serving cell of the UE that RLF takes place is carried out the back herein;
3) according to the UE that RLF takes place after the cell update success, receive the measurement report that reports after the measuring control information in new sub-district, obtain the pilot frequency intensity value of described TD-SCDMA Serving cell.
If UE cell update Cell Update success; then (can only be at the TD-SCDMA network) can receive the measurement control messages again in new sub-district; if satisfy certain condition; commonly used such as the 1G/2A incident; just be meant current service cell the neighbour district of pilot frequency intensity the pilot frequency intensity difference to a certain degree; and keep a period of time; UE will send measurement report to UTRAN so; also can know the pilot frequency intensity value of the peripheral cell of UE this moment; and the TD-SCDMA Serving cell that the UE of RLF takes place is just protected around in the sub-district, therefore can obtain to take place the pilot frequency intensity value that the TD-SCDMA Serving cell of the UE of RLF comes.
Because triggering cell was upgraded after RLF took place UE, network side utilizes the Cell Update message context that sends in the cell updating course to obtain the TD-SCDMA Serving cell ID (Identification that the UE of RLF takes place the user in the present embodiment, sign), also can utilize wherein locating information to obtain the positional information of UE simultaneously.In step S103, when redefining the GSM adjacent area of TD-SCDMA Serving cell, the GSM sub-district that sign UE position, UE the TD-SCDMA Serving cell position of RLF take place and exist on every side, the sub-district ID of above-mentioned situation etc. takes place in record, preferably, determine that the leakage of TD-SCDMA Serving cell adds the GSM adjacent area, specifically comprise: in described pilot frequency intensity value less than setting threshold, and when UE RLF and described pilot frequency intensity value take place reaches set point number less than the number of times of setting threshold in the setting-up time section, determine that described TD-SCDMA Serving cell leaks and add the GSM adjacent area.Promptly according to the accumulation judged result of a period of time, be specially certain section time the inside of statistics, it is more that the number of times of above-mentioned situation takes place in certain sub-district, determines then that the TD-SCDMA Serving cell leaks to add the GSM adjacent area and need redefine the GSM adjacent area.
