Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of handoff trigger method, system, test console, decoder and controller.
Background technology
Handover is portable terminal requisite process when communicating in mobile communication system, and the performance index of handover are one of key factors of the whole performance of mobile communication system quality of decision.
Handover be meant portable terminal from mobile communication system one or several base station communicate, carry out the transition to mobile communication system in another or the process that communicates of several base stations in addition, in the communications of Mobile Terminals process, handover can take place one time, also repeatedly handover can take place.Quantity according to the base station that communicates with portable terminal before and after switching is divided into different switching types with handover, below different switching types is elaborated.
As shown in Figure 1, comprise 7 zones in the overlay area of base station 1, base station 2 and base station 3, these 7 zones are called Zone switched, wherein, the signal that in Zone switched P1, only has base station 1, the signal that in Zone switched P2, only has base station 2, the signal that in Zone switched P3, has base station 1 and base station 2 simultaneously, the signal that only has base station 3 among the Zone switched P4, the signal that has base station 1 and base station 3 among the Zone switched P5 simultaneously, there is the signal of base station 1, base station 2 and base station 3 simultaneously in the signal that has base station 2 and base station 3 among the Zone switched P6 simultaneously among the Zone switched P7.
If portable terminal moves to Zone switched P3 from Zone switched P1, the switching type of the switching that portable terminal carried out is " one-plus-one switching " so, be to receive a signal of base station before portable terminal switches, not only original signal of base station can be received after the switching, a newly-increased signal of base station can also be received; If portable terminal moves to Zone switched P7 from Zone switched P3, the switching type of the switching that portable terminal carried out is " two add a switching " so, be to receive two signal of base station before portable terminal switches, not only can receive original two signal of base station after the switching, can also receive a newly-increased signal of base station; If portable terminal moves to Zone switched P7 from Zone switched P1, the switching type of the switching that portable terminal carried out is " one adds two switchings " so, be to receive a signal of base station before portable terminal switches, not only original signal of base station can be received after the switching, two newly-increased signal of base station can also be received; If portable terminal moves to Zone switched P5 from Zone switched P7, the switching type of the switching that portable terminal carried out is " three go a switching " so, be to receive three signal of base station before portable terminal switches, can only receive wherein two signal of base station after the switching; If portable terminal moves to Zone switched P1 from Zone switched P7, the switching type of the switching that portable terminal carried out is " three go two switchings " so, be to receive three signal of base station before portable terminal switches, can only receive one of them signal of base station after the switching; If portable terminal moves to Zone switched P6 from Zone switched P5, the switching type of the switching that portable terminal carried out is " two add a switching " so, be to receive two signal of base station before portable terminal switches, not only can receive original two signal of base station in the switching, a newly-increased signal of base station can also be received, wherein two signal of base station can only be received after the switching.
Above-mentioned switching type is basic switching type, these basic switching types can also be made up, obtain making up switching type, wherein, secondary combination switching type is the secondary combination of basic switching type, for example, portable terminal moves to Zone switched P3 from Zone switched P1, and then move to Zone switched P7, portable terminal has just carried out once " two after the one-plus-one switching adds a switching " so, this secondary combination switching type is the secondary combination of " one-plus-one switching " and " two add a switching " these two basic switching types, equally, portable terminal moves to Zone switched P3 from Zone switched P1, move to Zone switched P2 again, portable terminal has just carried out once " switching is gone in two after the one-plus-one switching " so, and this secondary combination switching type is the secondary combination of " one-plus-one switching " and " two go a switching " these two basic switching types.
When portable terminal switched between three base stations, switching type was very many, if base station number increases, it is long that switching type will be the index multiplication so.
As if the portable terminal handoff failure, then can improve the possibility of call drop, influenced user's subjective feeling, therefore, for mobile communication system, the test of handover success rate is most important.At present, the method of the handover success rate of test mobile communication system is generally: keep mobile terminal locations constant, the manual transmitting power of each base station of lifting repeatedly of tester, switch at each Zone switched with triggering mobile terminals, thereby obtain the handover success rate of mobile communication system.
Therefore, prior art is when the handover success rate of test mobile communication system, come triggering mobile terminals to carry out handover by the manual transmitting power of each base station of lifting repeatedly of tester, this method is very quick, efficient is extremely low but the manual repeatable operation of tester makes triggering, can't realize that the transmitting power of a plurality of base stations changes simultaneously by tester's manual operation, and the switching type of handover is very many, a lot of switching types need the transmitting power of a plurality of base stations to change simultaneously, therefore the switching type of the handover of prior art triggering is less, can not obtain accurately, comprehensive handover success rate.

More preferably, decoder 22 specifically is used for, according to default decoding rule, when the switching controls word that receives is deciphered, according to default decoding rule, the switching controls word that receives is deciphered, obtain corresponding encoded control word, then according to the encoded control word that obtains, determine the control command that the transmitting power of each base station that portable terminal is switched is controlled.
Preferably, decoder 22 specifically is used for, and at each base station, respectively the control corresponding instruction is sent to the base station transmitting power controller 23 of this base station.
Preferably, the handoff trigger system also comprises data acquisition unit, is used for when described portable terminal switches at every turn, from operation maintenance center (OMC, Operations ﹠amp; Maintenance Center) obtains the transmitting power of preceding each base station of described portable terminal switching, the transmitting power and the switching result information of each base station, switching back in, and transmitting power and the switching result information that obtains is sent to described test console 21;
Described test console 21 is determined handover information that described portable terminal this time switches according to the transmitting power that receives, and described handover information comprises Zone switched, the switching result Zone switched and that this time switch after switching this time before this time switching.
Based on above-mentioned handoff trigger system, the embodiment of the invention also provides a kind of handoff trigger method, and as shown in Figure 3, its concrete handling process is as follows:
Step 31, test console generate switching controls word sequence;
Wherein, test console is at first determined the transfer sequence of portable terminal when carrying out handover for each Zone switched, and according to the corresponding relation between the default Zone switched and switching controls word, each Zone switchedly is separately converted to corresponding switching controls word, according to switching controls word and described transfer sequence after transforming, generate switching controls word sequence then.
In the embodiment of the invention, when test console is determined the transfer sequence of portable terminal when carrying out handover for each Zone switched, earlier in each is Zone switched, choose the initially Zone switched of portable terminal, what will select then is initially Zone switched, it is current of living in Zone switched to confirm as described portable terminal, repeat following step, switching times until described portable terminal reaches default switching times threshold value: in Zone switched with current Zone switched adjacent each of living in of described portable terminal, choose the next Zone switched of described portable terminal, Zone switched with what select, it is current of living in Zone switched to confirm as described portable terminal.
When test console is chosen described portable terminal next Zone switched, can picked at random, also can choose based on constraints, at this moment, test console is according to the constraints of the current Zone switched correspondence of living in of described portable terminal, in Zone switched, choose the next Zone switched of described portable terminal with current Zone switched adjacent each of living in of described portable terminal.
The method of above-mentioned definite transfer sequence also can be called the random algorithm based on constraint, this thought of random algorithm based on constraint be exactly according to portable terminal current of living in Zone switched calculate might switch to Zone switched, and therefrom choose one Zone switched, Zone switched as the next one, and then with this Zone switched as portable terminal current of living in Zone switched calculate next Zone switched, so circulation can infinitely go on.
Above-mentioned constraints has multiple, can determine according to the test needs by the tester, for example, as shown in Figure 1, from physical location, when portable terminal is in Zone switched P1, its might switch to Zone switched Zone switched P3 arranged, Zone switched P5 and Zone switched P7, but according to the test needs, in the time of can retraining portable terminal and be in Zone switched P1, can only switch to Zone switched P3, perhaps, according to the test needs, can retrain portable terminal is 1/2nd from the probability that Zone switched P1 switches to Zone switched P3, and portable terminal is 1/4th from the probability that Zone switched P1 switches to Zone switched P5 and P7, be similar in the actual scene and have only a road to Zone switched P5 from Zone switched P1, perhaps from Zone switched P1 to Zone switched P3, P5, the probability difference that P7 moves, such scene are very common in mobile communication system, therefore above-mentioned random algorithm based on constraint can make the test of handover success rate truer.
In the embodiment of the invention, set in advance the switching controls word of each Zone switched correspondence, as shown in Figure 1, the switching controls word that Zone switched P1 correspondence is set is 1, the switching controls word of Zone switched P2 correspondence is 2, the switching controls word of Zone switched P3 correspondence is 3, and the like.
If the transfer sequence determined is P1 → P5, then the switching controls word sequence of Sheng Chenging be 1,5} is P1 → P5 → P4 as if the transfer sequence of determining, and then the switching controls word sequence of Sheng Chenging be 1,5,4}.
Step 32, test console send to decoder with each the switching controls word in the switching controls word sequence successively;
After test console generates switching controls word sequence, successively each the switching controls word in the switching controls word sequence is sent to decoder, for example, the switching controls word sequence that generates is { 1,5,4}, then test console sends to decoder with switching controls word 1 earlier, then after the time interval through a setting, switching controls word 5 is sent to decoder, and then after the time interval through a setting, switching controls word 4 being sent to decoder, the time interval of above-mentioned setting is determined by the control word transmission speed.
The embodiment of the invention proposes, test console can be according to the random algorithm based on constraint, generate complete switching controls word sequence in advance, the length controlled of this sequence, when test console generates switching controls word sequence, number, these initial parameters of control word transmission speed of reference sequences length, base station number, the maximum receivable base station signal of portable terminal.
In addition, test console also can produce switching controls word sequence in the handoff trigger process, Yi Bian promptly successively each the switching controls word in the switching controls word sequence is sent to decoder, Yi Bian continue to generate switching controls word sequence.
Step 33, decoder generate control command according to the switching controls word that receives, and the control command that generates is sent to the relevant base station transmitting power controller;
Wherein, decoder, according to default decoding rule, is deciphered the switching controls word that receives when generating control command according to the switching controls word that receives, and obtains the control command that the transmitting power of each base station is controlled.
Decoder is according to default decoding rule, the switching controls word that receives is deciphered, obtain corresponding encoded control word,, determine the control command that the transmitting power of each base station that portable terminal is switched is controlled then according to the encoded control word that obtains.
In addition, when decoder sends to the relevant base station transmitting power controller with the control command that generates,, respectively the control corresponding instruction is sent to the base station transmitting power controller of this base station at each base station.
In the embodiment of the invention, the respectively corresponding encoded control word of each switching controls word, for example, the encoded control word of switching controls word 5 correspondences is 101, and each numeral in 101 is all represented a base station, first digit is represented base station 1, and second digit is represented base station 2, and third digit is represented base station 3, can represent each base station with binary digit, if the transmitting power of base station is non-vanishing, then Dui Ying binary digit is 1, if the transmitting power of base station is zero, then Dui Ying binary digit is 0, each encoded control word all represent one Zone switched, for example, as shown in Figure 1, the transmitting power of switching controls word 101 expression base stations 1 is non-vanishing, the transmitting power of base station 2 is zero, and the transmitting power of base station 3 is non-vanishing, and the Zone switched of correspondence is Zone switched P5.
Test console sends to switching controls word 5 after the decoder, decoder is decoded as 101 with this switching controls word, the transmitting power of determining base station 1 then is non-vanishing, the transmitting power of base station 2 is zero, and the transmitting power of base station 3 is non-vanishing, therefore obtain control command that the transmitting power of base station 1 is controlled for transmitting, the control command that the transmitting power of base station 2 is controlled is not for transmitting, and the control command that the transmitting power of base station 3 is controlled is for transmitting.
Step 34, the base station transmitting power controller carries out the control of transmitting power according to the control command that receives to relevant base station, carries out handover to trigger described portable terminal according to described transfer sequence.
If the control command that the base station transmitting power controller receives is for transmitting, then controlling relevant base station transmits, if the control command that the base station transmitting power controller receives is not for transmitting, then controlling relevant base station does not transmit, thereby the control portable terminal switches in each is Zone switched according to the transfer sequence of determining, and can trigger the handover of various needed switching types.
The base station transmitting power controller can use the numerical control switch that the base station is controlled.If the quantity of base station is 8 or less than 8, then can use three or eight decoders, if the quantity of base station is bigger, then can use two three or eight decoders.
