The schematic diagram of the procedure of the detection uplink interference that Fig. 1 provides for the embodiment of the invention, as shown in Figure 1, this method may further comprise the steps:
S101: when the received power value when the base station on the specified upstream physical resource is not more than default received power threshold, determine the up signal interference ratio of each user terminal of use specified upstream physical resource;
S102: during less than the quantity of the user terminal of default up signal interference ratio threshold value, determine that described each user terminal is subjected to discontinuous uplink interference more than up signal interference ratio greater than the quantity of the user terminal of default up signal interference ratio threshold value at up signal interference ratio.
The received power value of base station can measure by the physical layer of base station.Such as, for the WCDMA system, can be the received power measured value of definition among the 5.2.1 joint Received total wide band power (reception total bandwidth power) among the 3GPP agreement TS25.215; For the TD-SCDMA system, can be the received power measured value that defines among the 5.2.3 joint Received total wide band power in the 3GPP agreement 25.225.
Up signal interference ratio can measure by the physical layer of base station.Such as, for the WCDMA system, can be 5.2.2 joint SIR(Signal to Interference Ratio among the 3GPP agreement TS25.215, signal interference ratio) the middle signal-to-interference ratio measurement value that defines; For the TD-SCDMA system, can be the signal-to-interference ratio measurement value that defines among the 5.2.4 joint SIR in the 3GPP agreement 25.225.Up signal interference ratio also can be by calculating, and obtains the up signal interference ratio of this user terminal divided by uplink interference intensity by the up reception signal strength signal intensity of user terminal that the base station is received.
The method of determining the received power value of the up signal interference ratio of user terminal and base station is not limited thereto, and only is example here.
When the method for passing through the measurement of base station physical layer obtained the received power value of base station, the received power value of base station was that the base station physical layer is measured the preceding measured value of decay.
Default received power threshold and default up signal interference ratio threshold value can and be decided according to system's realization.Preferably, default up signal interference ratio threshold value is the up signal interference ratio desired value in the uplink power control, and namely the transmitting power by uplink power control process adjustment user terminal makes the up signal interference ratio of user terminal reach this up signal interference ratio desired value.Under normal circumstances, uplink power control control effectively to the uplink transmission power of user terminal, so that the up signal interference ratio of user terminal equals up signal interference ratio desired value.Such as, when the uplink interference that is subjected to when user terminal is big, can pass through uplink power control, increase the uplink transmission power of user terminal, and then make the up signal interference ratio of user terminal equal up signal interference ratio desired value, the proper communication of assurance user terminal.
Discontinuous uplink interference refers to that to the uplink interference that each user terminal causes be discontinuous, the interference magnitude real-time change.Such as, when to the uplink interference of each user terminal during from the user terminal of other base stations, if the user terminal of these other base stations is carrying out discontinuous business, such as browsing page etc., it will cause discontinuous interference to each user terminal of this base station.Discontinuous interference can make the signal interference ratio of each user terminal of this base station occur than great fluctuation process, has a strong impact on communication quality.
When user terminal was subjected to stronger uplink interference or discontinuous uplink interference, uplink power control can't make the up signal interference ratio of user terminal equal up signal interference ratio desired value, and the up signal interference ratio that user terminal can occur departs from up signal interference ratio desired value.Such as, when user terminal is subjected to discontinuous uplink interference, the interference value fast rise, pass through uplink power control, the uplink transmission power of user terminal will promote, and when interference value descended fast subsequently, uplink power control did not also have enough time to reduce the uplink transmission power of user terminal, namely causes the up signal interference ratio of user terminal greater than up signal interference ratio desired value.
In the method that the embodiment of the invention provides, by more up signal interference ratio greater than the quantity of the user terminal of default up signal interference ratio threshold value and the up signal interference ratio quantity less than the user terminal of default up signal interference ratio threshold value, the disturbed condition that each user terminal of next definite use specified upstream physical resource is subjected to, when the former quantity during more than latter's quantity, confirm to use each user terminal of specified upstream physical resource to be subjected to discontinuous uplink interference.
Wherein, the specified upstream physical resource can comprise a kind of in the following physical resource:
The one or more up frequency of a residential quarter of base station;
One or more ascending time slots of a frequency of a residential quarter of base station;
One or more code channels of an ascending time slot of a frequency of a residential quarter of base station;
One or more ascending physical signal Resource Block of a residential quarter of base station.
Such as, for the WCDMA system, specific ascending physical signal resource can be one or more up frequencies; For the TD-SCDMA system, specific ascending physical signal resource can be one or more code channels of an ascending time slot of a frequency of a residential quarter of one or more ascending time slots of a frequency of a residential quarter of base station or base station; For the LTE system, specific ascending physical signal resource can be a residential quarter of base station one or more ascending physical signal Resource Block (Physical Resource Block, PRB).The actual physical resource is not limited thereto, and is example only here, is not restricted.
Alternatively, when the up signal interference ratio of each user terminal that uses the specified upstream physical resource is equal to default up signal interference ratio threshold value, think that the uplink interference situation is normal, do not do any processing.
Preferably, the method for the detection uplink interference that provides of the embodiment of the invention also comprises:
When the received power value of base station on the specified upstream physical resource greater than default received power threshold, and the attenuation of base station receiver on the specified upstream physical resource increases the attenuation of base station receiver on the specified upstream physical resource during less than default base station receiver attenuation threshold value.
Usually, the received power value of base station on the specified upstream physical resource has two kinds to produce reason greater than default received power threshold:
The transmitting power of reason one, user terminal has reached the minimum emissive power restriction, and this user terminal is nearer from the reception antenna of base station, the received power value of the upward signal that this user terminal that makes the base station receive is launched is bigger, make the received power value of base station greater than default received power threshold, even cause base station receiver to overflow;
Reason two, there is the edge of overlay area of its described residential quarter of user terminal of non-this base station, in order to guarantee operate as normal, this user terminal transmits with bigger uplink transmission power, this base station receives the bigger upward signal of this user terminal emission, cause this base station received power value higher, make the received power value of base station greater than default received power threshold, even cause base station receiver to overflow.
Therefore, when the received power value of base station on the specified upstream physical resource during greater than default received power threshold, can judge roughly that the user terminal of the use specified upstream physical resource of this base station receives uplink interference, and then by increasing the attenuation of base station receiver on the specified upstream physical resource, suppress this uplink interference.The prerequisite that increases the attenuation of base station receiver on the specified upstream physical resource is that the attenuation of base station receiver on the specified upstream physical resource is less than default base station receiver attenuation threshold value.
In an embodiment of the present invention, the method for adjustment to the base station receiver attenuation includes but not limited to following several:
Method one, according to the received power value of present base station on the specified upstream physical resource, the adjusted value that default received power threshold is determined the base station receiver attenuation.
Such as: the received power value-100dBm of present base station on the specified upstream physical resource, default received power threshold is-95dBm, then the base station receiver attenuation can be reduced 5dB, make the received power threshold that the received power value of base station on the specified upstream physical resource equals to preset.
The attenuation adjustment amount of method two, base station receiver equals Δ ATT*n, and wherein, Δ ATT is that attenuation is adjusted step value, and n is that attenuation is adjusted multiple, n 〉=1, and n is integer.The value of n can be adjusted as required flexibly, such as when needs increase attenuation fast, can realize rapid adjustment by increasing n.Alternatively, n=1 namely only adjusts single attenuation at every turn and adjusts step value.
Preferably, the method for the detection uplink interference that the embodiment of the invention provides also comprises after definite each user terminal is subjected to discontinuous uplink interference:
If the attenuation of base station receiver on the specified upstream physical resource greater than 0, reduces the attenuation of base station receiver on the specified upstream physical resource.
When user terminal is subjected to discontinuous uplink interference, the up signal interference ratio that causes user terminal is greater than default up signal interference ratio threshold value if uplink interference die-offs, at this moment, if the uplink power control to user terminal is not instant, or the uplink power control effect is bad, too small such as arranging of uplink power control step-length, do not have rapidly the uplink transmission power of user terminal to be adjusted to desired value when disturbing when reducing, make that the uplink transmission power of user terminal is still higher, may cause the received power value of base station excessive, receiver overflows easily, so will increase the attenuation of base station receiver.
Preferably, the method for the detection uplink interference that the embodiment of the invention provides also comprises after the up signal interference ratio of each user terminal of determining use specified upstream physical resource:
If up signal interference ratio is no less than up signal interference ratio greater than the quantity of the user terminal of default up signal interference ratio threshold value and non-vanishing less than the quantity of the user terminal of default up signal interference ratio threshold value, and the attenuation of base station receiver on the specified upstream physical resource increases the attenuation of base station receiver on the specified upstream physical resource less than default base station receiver attenuation threshold value.
If up signal interference ratio is no less than up signal interference ratio greater than the quantity of the user terminal of default up signal interference ratio threshold value and non-vanishing less than the quantity of the user terminal of default up signal interference ratio threshold value, can determine that each user terminal has been subjected to stronger uplink interference, and uplink power control can't improve up signal interference ratio, and reduce uplink interference by increasing the attenuation of base station receiver on the specified upstream physical resource this moment.When the attenuation that has increased base station receiver, the user terminal of the up signal interference ratio threshold value that up signal interference ratio equals to preset can be under the effect of uplink power control, increase the uplink transmission power of self, remedy the reduction of the user terminal upward signal that base station that the attenuation that increases base station receiver causes receives.The user terminal of the up signal interference ratio threshold value that the attenuation that therefore increases base station receiver can not equal to preset to up signal interference ratio exerts an influence.
Preferably, the method of the detection uplink interference that the embodiment of the invention provides also comprises: when the received power value of base station on the specified upstream physical resource greater than default received power threshold, and the attenuation of base station receiver on the specified upstream physical resource increases by the first attenuation steps value with the attenuation of base station receiver on the specified upstream physical resource during less than default base station receiver attenuation threshold value;
After the up signal interference ratio of each user terminal of determining use specified upstream physical resource, also comprise:
If up signal interference ratio is no less than up signal interference ratio greater than the quantity of the user terminal of default up signal interference ratio threshold value and non-vanishing less than the quantity of the user terminal of default up signal interference ratio threshold value, and the attenuation of base station receiver on the specified upstream physical resource increases by the second attenuation steps value less than default base station receiver attenuation threshold value with the attenuation of base station receiver on the specified upstream physical resource;
Determine that described each user terminal is subjected to also comprising after the discontinuous uplink interference:
If the attenuation of base station receiver on the specified upstream physical resource greater than 0, reduces by the 3rd attenuation steps value with the attenuation of base station receiver on the specified upstream physical resource;
Wherein, the 3rd attenuation steps value is less than in the first attenuation steps value and the second attenuation steps value any one.
Here, by adjusting the adjustment that single step value carries out the base station receiver attenuation.For different uplink interference situations, the attenuation steps value can be set respectively.For sake of clarity, disturbed condition is wherein sorted out following as shown in table 1:
Table 1
In the table 1, RP represents when the received power value of base station on the specified upstream physical resource, RP_TH represents the received power threshold preset, SIR represents the up signal interference ratio of user terminal, SIR_TH represents the up signal interference ratio threshold value preset, SIR〉SIR_TH represent to use up signal interference ratio SIR in each user terminal of specified upstream physical resource greater than the quantity of the user terminal of default up signal interference ratio threshold value SIR_TH more than the quantity of up signal interference ratio SIR less than the user terminal of default up signal interference ratio threshold value SIR_TH, SIR＜SIR_TH represents to use up signal interference ratio SIR in each user terminal of specified upstream physical resource to be no less than up signal interference ratio SIR greater than the quantity of the user terminal of default up signal interference ratio threshold value SIR_TH less than the quantity of the user terminal of default up signal interference ratio threshold value SIR_TH, ATT represents the base station receiver attenuation, and ATT1 represents the first attenuation steps value, ATT2 represents the second attenuation steps value, ATT3 represents the 3rd attenuation steps value.
Wherein ATT3＜ATT1, and ATT3＜ATT2, the purpose of She Dinging is like this: when each user terminal is subjected to discontinuous uplink interference, mean that the variable quantity of uplink interference value in the unit interval that each user terminal is subjected to is bigger.At this moment, should not adjust the attenuation of base station receiver very little, this be because, though at current time, the signal interference ratio of user terminal is greater than default signal interference ratio threshold value, but next is constantly probably, uplink interference rises sharply, if significantly reduce suddenly in the attenuation of current time with receiver, then at next when constantly uplink interference rises sharply, owing to there be not the inhibition of receiver decay to disturbing, the uplink interference that rises sharply may cause that the up signal interference ratio of user terminal die-offs, influence the communication quality of user terminal, even may cause call drop.For fear of the influence of discontinuous interference to the user terminal signal interference ratio, therefore consider to reduce attenuation with less attenuation steps, but and not exclusively be reduced to 0, the self adaptation adjustment of attenuation can better suppress discontinuous interference, when uplink interference rises sharply, attenuation still exists, and can be used for suppressing to disturb.
In addition, need to prove, when RP＜=RP_TH and SIR=SIR_TH(are that the up signal interference ratio SIR of each user terminal is equal to default up signal interference ratio threshold value SIR_TH) time, can determine that the uplink interference situation is normal, need not adjust this moment to the attenuation of base station receiver.
Preferably, compare with the up signal interference ratio threshold value of presetting according to the up signal interference ratio of the following step with user terminal:
At a user terminal, determine the up signal interference ratio threshold value of the type of service corresponding preset of this user terminal;
The up signal interference ratio threshold value of the type of service corresponding preset of the up signal interference ratio of this user terminal and this user terminal is compared.
For different types of service, the up signal interference ratio threshold value of corresponding preset can be set.Such as, for speech business, it is had relatively high expectations to up signal interference ratio, default up signal interference ratio threshold value that can this type of service is set to bigger value, such as 7dB, for the data service of background classes, its requirement to up signal interference ratio is lower, default up signal interference ratio threshold value that can this type of service is set to less value, such as 5dB.In the practical application, the method that default up signal interference ratio threshold value is set has a lot, gives unnecessary details no longer one by one here.
The uplink interference sense cycle T that the process of the uplink interference detection method that the embodiment of the invention provides can be preset carries out, and perhaps carries out during at least one in satisfying following condition:
Condition one, base station are measured threshold value at the uplink interference measured value that the specified upstream physical resource is subjected to greater than default uplink interference;
The user terminal of condition two, use specified upstream physical resource inserts success rate and is lower than default access success rate threshold value;
The user terminal cutting off rate of condition three, use specified upstream physical resource is greater than default cutting off rate threshold value.
Wherein, for the TD-SCDMA system, uplink interference measured value in the condition one can be the slot interfering signal of time sign indicating number performance number (Timeslot Interference Signal Code Power, Timeslot ISCP) that defines in the 5.2.2 joint of 3GPP agreement TS25.225.
Condition two, the 3rd determines whether to carry out the procedure of the detection uplink interference that the embodiment of the invention provides by the traffic statistic result.Higher and/or insert success rate when low when the cutting off rate of the user terminal that uses the specified upstream physical resource, but the uplink interference situation that the preliminary judgement user terminal is subjected to is unusual, at this moment, the method for the detection uplink interference that the execution embodiment of the invention provides is accurately to determine the uplink interference situation.
