Step 3205: obtain the measured value of operation level of travelling carriage A and the measured value of signal quality, respectively itself and default level threshold value and signal quality threshold value are compared, obtain comparative result A.
In the present embodiment, have only the measured value of the operation level of travelling carriage A to be higher than default level threshold value, when the measured value of the signal quality of travelling carriage A was higher than default signal quality threshold value simultaneously, the value of comparative result A just was " 1 ", and equal value is " 0 " under other situations
Step 3206: obtain the measured value of operation level of travelling carriage B and the measured value of signal quality, respectively itself and default level threshold value and signal quality threshold value are compared, obtain comparative result B.
The same, in the present embodiment, have only the measured value of the operation level of travelling carriage B to be higher than default level threshold value, when the measured value of the signal quality of travelling carriage B is higher than default signal quality threshold value simultaneously, the value of comparative result B just is " 1 ", and equal value is " 0 " under other situations
Step 3207: according to comparative result A, comparative result B and default judgement reference table, obtain to be used to indicate how to carry out the court verdict that intra-cell is changed, then, carry out step 330.
Consult shown in the table 1, in the present embodiment, different according to comparative result A and comparative result B value are provided with the court verdict of four kinds of correspondences respectively, and its value is respectively 0,1,2,3.
Table 1
| Comparative result A | Comparative result B | Court verdict |
| ??0 | ??0 | ??0 |
| ??1 | ??0 | ??1 |
| ??0 | ??1 | ??2 |
| ??1 | ??1 | ??3 |
As shown in table 1, in the present embodiment, the instruction content that four kinds of values of corresponding court verdict define respectively is as follows:
If the court verdict value is 0, show that then court verdict is: need not that travelling carriage A and travelling carriage B are carried out intra-cell and change;
If the court verdict value is 1, show that then court verdict is: need carry out intra-cell to travelling carriage A and change.
If the court verdict value is 2, show that then court verdict is: need carry out intra-cell to travelling carriage B and change.
If the court verdict value is 3, show that then court verdict is: need obtain the signal transmission power of travelling carriage A and travelling carriage B, and draw power ratio P
AB_DB=10*lg (p
_ A/ p
_ B), if P
AB_DB＜0db then carries out intra-cell to travelling carriage A and changes, if P
AB_DB＞0db then carries out intra-cell to travelling carriage B and changes; Its judgement principle is the less travelling carriage of first power switched.
Based on above-mentioned two embodiment, in step 340, according to the court verdict that obtains, base station controller 10 may change execution algorithm based on the intra-cell of MUROS technology at travelling carriage A or travelling carriage B execution, in the present embodiment, be that example is introduced still, consult shown in Figure 5ly that base station controller 10 carries out at travelling carriage A that to change the detailed process of execution algorithm based on the intra-cell of MUROS technology as follows with travelling carriage A:
Step 3400: all channel resources in the traversal compass of competency judge whether to exist the idle channel that is not taken by Any user, if then carry out step 3404; Otherwise, carry out step 3401.
Step 3401: further judge whether to have the idle channel that takies separately by other MUROS users (hereinafter referred to as travelling carriage C), if then carry out step 3402; Otherwise, carry out step 3403.
Step 3402: calculate the ratio of the signal transmission power of travelling carriage A and travelling carriage C, and whether judge this ratio less than default power threshold P_target, if, then carry out step 3404, otherwise, carry out step 3403.
Because the DARP receiver can come out signal demodulation from the more approaching co-channel interference signal of power ratio, so it is approaching more good more to wish to take two MUROS users' the signal transmission power of same channel, preferably ratio is 1: 1, therefore, establishing power threshold P_target is in order to make the signal transmission power of travelling carriage A and travelling carriage C approaching as far as possible.
Step 3403: determine that execution result is: intra-cell is changed and is carried out failure, then, carry out step 350.
Step 3404: travelling carriage A is switched to definite idle channel, and definite execution result is: the sub-district switching runs succeeded, and then, carry out step 350.
In the present embodiment, can adopt DCA algorithm, DFCA algorithm or insert algorithm at random and travelling carriage A is carried out intra-cell change.
In sum, based on above-mentioned three embodiment, when base station controller 10 determines that travelling carriage A is MUROS user, judge whether to exist the travelling carriage B that shares same channel with travelling carriage A earlier, if there is not described travelling carriage B, then meet when pre-conditioned in the operating state of determining travelling carriage A, judgement is carried out intra-cell to travelling carriage A and is changed; If there is travelling carriage B, then the operating state of travelling carriage A and the operating state of travelling carriage B compared with pre-conditioned respectively, and according to the comparative result judgement travelling carriage A or travelling carriage B are carried out intra-cell and change.Like this, just can be in the gsm system that adopts the MUROS technology realize that at MUROS user intra-cell changes, thereby under the prerequisite that improves the system bearing amount, guaranteed the service quality of mobile data services, and then promoted user experience to a certain extent.
Obviously, those skilled in the art can carry out various changes and modification to the embodiment among the present invention and not break away from the spirit and scope of the present invention.Like this, if these in the embodiment of the invention are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the embodiment among the present invention also is intended to comprise these changes and modification interior.
