Embodiment
GSM adjacent area adding method and the equipment of the TD-SCDMA residential quarter that the present invention is proposed below in conjunction with drawings and Examples illustrate in greater detail.
In embodiments of the invention, the GSM adjacent area adding method of a kind of TD-SCDMA residential quarter is provided, as shown in Figure 1, the 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) occurs;
As previously mentioned, in user terminal UE start access TD-SCDMA network development process, 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 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 coverage strength 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 configure 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 of configuration, 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, received signal strength indicator) etc., metrical information is reported network side; Whether network side indicates UE to GSM adjacent area switching according to metrical information; When network side indication UE switched to the GSM adjacent area, UE switched to the GSM adjacent area from current TD-SCDMA Serving cell; When network side indication UE did not switch to the GSM adjacent area, the UE occurrence cause was the cell update Cell Update message process of RLF.
As seen, UE be in cover poor environment in the time, do not configuring the GSM adjacent area, or disposing the GSM adjacent area and do not satisfy through the GSM nearby region measurement and switch when requiring, Radio Link Failure RLF occurs in UE, thereby 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 represents the coverage strength of this TD-SCDMA Serving cell.after the pilot frequency intensity value of the TD-SCDMA residential quarter of the UE that RLF to occur, in this enforcement, this pilot frequency intensity value and setting threshold (P+ δ) are compared, wherein P represents an absolute strength value, δ represents a surplus, if this value is less than this thresholding, just think that the current residing position TD-SCDMA of UE covers relatively poor, be judged as herein UE and should switch to certain GSM residential quarter, and add the GSM adjacent area because the TD-SCDMA Serving cell leaks, be currently there is no the GSM adjacent area that to switch and do not switch, cause the user in the TD-SCDMA network, RLF to occur and triggering cell renewal Cell Update process.
If in the present embodiment, the pilot frequency intensity value of TD-SCDMA Serving cell is not less than above-mentioned setting threshold, determine that the TD-SCDMA Serving cell does not have leakage to add the GSM adjacent area, but because RLF occurs 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 by the most recent layout information table that imports TD-SCDMA residential quarter and GSM network cell in the present embodiment.
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 according to some principles of the existing GSM adjacent area of determining the TD-SCDMA residential quarter the GSM adjacent area of above-mentioned TD-SCDMA Serving cell.
Step S104 adds the GSM adjacent area that redefines to described TD-SCDMA Serving cell.
Like this, in UE start next time access TD-SCDMA network development process, the TD-SCDMA Serving cell sends to UE with GSM neighbor cell configuration situation.After UE is linked into the TD-SCDMA network, UE be in cover poor environment in the time, can realize switching to the GSM adjacent area of new configuration, owing to being up-to-date and the actual GSM cell configuration that conforms to, so can successfully realize to the switching of GSM adjacent area.Utilize the present invention can find automatically at network side that the GSM adjacent area of TD-SCDMA residential quarter 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 send to the cell update Cell Update message of UTRAN (land radio access web) to obtain some information of UE (such as the residential quarter ID of access by UE, the pilot frequency information of residential quarter, the sign of UE, reason of cell update etc.).Based on this analysis result, can obtain some pilot frequency informations that RLF occurs and whether carry out occuring because adding the GSM adjacent area judgement of RLF, during concrete enforcement, obtain the pilot frequency intensity value of the TD-SCDMA Serving cell of the UE that RLF occurs at step S101, can adopt in following three kinds of modes any:
1) the 6A event report and/or the 5A event report that report before cell update according to the UE that RLF occurs, obtain the pilot frequency intensity value of TD-SCDMA Serving cell, wherein the 6A event report is the measurement report that the transmitted power of UE reports when setting thresholding, it is the measurement report of the additional pilots of the 6A that stipulates in standard, the 5A event report is the measurement report that the bLock error rate BLER (Block Error Ratio) of UE the transmission of data reports during greater than set point, the measurement report of the additional pilots of the 5A that namely stipulates in standard.The pilot frequency intensity value of the residing Serving cell of UE and all adjacent cells before this two classes measurement report all can reporting cell upgrades.Therefore, can obtain to occur the pilot frequency intensity value of TD-SCDMA Serving cell of the UE of RLF from this two classes measurement report.
2) the cell update message that reports in cell updating course according to the UE that RLF occurs is obtained the pilot frequency intensity value of described TD-SCDMA Serving cell.
Obtain from network side the Cell Update message that UE reports cell updating course, therefrom obtain the TD-SCDMA Serving cell No. ID, 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 occur, may be also that UE completes current TD-SCDMA Serving cell of communicating by letter after 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 occurs is carried out the back herein;
3) according to the UE that RLF occurs after the cell update success, receive the measurement report that reports after measuring control information in new residential quarter, obtain the pilot frequency intensity value of described TD-SCDMA Serving cell.
if UE cell update Cell Update success, (can only be at the TD-SCDMA network) can receive the measurement control message again in new residential quarter, if satisfy certain condition, commonly used such as the 1G/2A event, the neighbour pilot frequency intensity of distinguishing of pilot frequency intensity that just refers to current service cell is to a certain degree poor, 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 occurs is just protected around in the residential quarter, therefore can obtain to occur the pilot frequency intensity value that the TD-SCDMA Serving cell of the UE of RLF comes.
