本发明适用于移动通信系统,尤其适用于全球移动通信系统(GSM,Global System for Mobile Communication),所述下电载频的选择过程由移动通信系统中的基站控制器(BSC)执行;BSC选择好下电载频后,通知基  站收发信机(BTS),由该BTS执行对该载频进行的下电操作,BTS的具体下电操作为现有技术,本发明主要对下电载频的选择过程进行说明。  The present invention is applicable to mobile communication system, especially applicable to Global System for Mobile Communication (GSM, Global System for Mobile Communication), and the selection process of described off-power carrier frequency is carried out by the base station controller (BSC) in the mobile communication system; BSC selection After the carrier frequency is off, notify the base Station transceiver (BTS), the BTS performs the power-off operation on the carrier frequency. The specific power-off operation of the BTS is the prior art. The present invention mainly explains the selection process of the power-off carrier frequency. the

本发明中,选择下电载频必须考虑的选择因素为载频的信道属性,作为必要选择因素的载频信道属性信息按照下电优先级依次包括:  In the present invention, the selection factor that must be considered in selecting the power-off carrier frequency is the channel attribute of the carrier frequency, and the carrier frequency channel attribute information as a necessary selection factor includes in order according to the power-off priority:

a)是否为广播控制信道(BCCH,Broadcast Control Channel)载频。  a) Whether it is the broadcast control channel (BCCH, Broadcast Control Channel) carrier frequency. the

b)是否为第一子小区的载频。所述第一子小区为业界公知的小区同心圆配置时的内圆,也就是说在一个小区配置成同心圆时,将小区划分成了两个或者更多的子小区,其中的内圆称之为第一子小区。  b) Whether it is the carrier frequency of the first sub-cell. The first sub-cell is the inner circle when concentric circles are well-known in the industry, that is to say, when a cell is configured as a concentric circle, the cell is divided into two or more sub-cells, and the inner circle is called It is the first sub-district. the

c)小区内除本载频外剩余载频中是否有电路域(CS)信道和分组域(PS)信道。所述的CS信道例如可以为话务信道(TCH,Traffic Channel),所述的PS信道例如可以为分组数据话务信道(PDTCH,Packet Data TrafficChannel)信道等。  c) Whether there are circuit domain (CS) channels and packet domain (PS) channels in the remaining carrier frequencies in the cell except the current carrier frequency. The CS channel can be, for example, a traffic channel (TCH, Traffic Channel), and the PS channel can be, for example, a packet data traffic channel (PDTCH, Packet Data Traffic Channel) channel, etc. the

针对上述每种必要选择因素需要对应设置选择策略,本发明需要根据以下优先级的选择策略顺序依次选择需要下载的载频:  For each of the above-mentioned necessary selection factors, a selection strategy needs to be set correspondingly. The present invention needs to select the carrier frequency to be downloaded in sequence according to the following priority selection strategy order:

首先,非BCCH载频优先下电;  First, the non-BCCH carrier frequency is powered off first;

其次,优先下电第一子小区内的载频;  Secondly, the carrier frequency in the first sub-cell is preferentially powered off;

再次,选择的本载频下电后,小区内剩余载频中是否有CS信道和PS信道,有则优先下电本载频。  Again, after the selected local carrier is powered off, whether there are CS channels and PS channels among the remaining carrier frequencies in the cell, the local carrier will be powered off first. the

为了进一步优化本发明,除了上述必须考虑的选择因素之外,本发明在选择下电载频时还需要考虑一些扩展的选择因素。  In order to further optimize the present invention, in addition to the selection factors that must be considered above, the present invention also needs to consider some extended selection factors when selecting the power-down carrier frequency. the

在本发明的一种优选实施方式中,扩展的选择因素可以为:d)载频话务量指标;e)载频性能指标。在一种优选实施例中,所述载频的话务量指标为载频的信道占用比,所述载频的性能指标为载频的掉话率。  In a preferred embodiment of the present invention, the expanded selection factors may be: d) carrier frequency traffic index; e) carrier frequency performance index. In a preferred embodiment, the traffic index of the carrier frequency is the channel occupancy ratio of the carrier frequency, and the performance index of the carrier frequency is the call drop rate of the carrier frequency. the

上述每种扩展选择因素对应的选择策略是:  The selection strategy corresponding to each of the above expansion selection factors is:

1)话务量最低的载频优先下电;  1) The carrier frequency with the lowest traffic is powered off first;

2)性能最差的载频优先下电。  2) The carrier frequency with the worst performance is powered off first. the

以上是本发明在选择下电载频时的选择因素及每种选择因素对应的选  择策略,为了准确地选择最恰当的载频以进行智能下电,需要根据上述选择因素及其选择策略对当前小区中的各个载频分别确定一个量化的值,根据该量化值进行智能下电选择。  The above are the selection factors of the present invention when selecting the power-down carrier frequency and the selection corresponding to each selection factor. In order to accurately select the most appropriate carrier frequency for intelligent power-off, it is necessary to determine a quantized value for each carrier frequency in the current cell according to the above selection factors and the selection strategy, and perform intelligent power-off according to the quantified value. choose. the

本发明中,可以为小区中每个载频设置一个下电权值,该下电权值是一个二进制数,其位数根据所述选择因素确定,必要选择因素对应高位,并且每种必要选择因素独占一位,扩展选择因素则对应后几位。例如上述必要选择因素有三个,那么在一种实施例中所述下电权值至少要有三位分别与每个必要选择因素对应,从高位到低位依次对应上述选择因素a)、b)、c);上述的扩展选择因素d)和e)可以用于确定所述下电权值的低位的取值,因此所述下电权值的低位的位数需要能够容纳扩展选择因素确定的取值范围,在本发明的一种较佳实施例中,所述下电权值由扩展选择因素确定的位数为四位。  In the present invention, a power-off weight value can be set for each carrier frequency in the cell. The power-off weight value is a binary number whose digits are determined according to the selection factors, and the necessary selection factors correspond to high bits, and each necessary selection factor The factor occupies one digit alone, and the extended selection factor corresponds to the last few digits. For example, there are three above-mentioned necessary selection factors, so in one embodiment, the power-off weight value must have at least three bits corresponding to each necessary selection factor, corresponding to the above-mentioned selection factors a), b), and c in sequence from high to low. ); the above-mentioned extended selection factors d) and e) can be used to determine the value of the low order of the power-off weight, so the low-order digits of the power-off weight need to be able to accommodate the value determined by the extended selection factor Range, in a preferred embodiment of the present invention, the number of digits of the power-off weight determined by the extended selection factor is four digits. the

所述下电权值的初始值为0,BSC首先需要确定所述各个选择因素的具体情况,根据各个选择因素是否符合对应的选择条件确定对应位的值,例如如果该位对应的必要选择因素符合选择条件则置1,否则置0。  The initial value of the power-off weight is 0. The BSC first needs to determine the specific conditions of each selection factor, and determine the value of the corresponding bit according to whether each selection factor meets the corresponding selection condition. For example, if the necessary selection factor corresponding to this bit Set to 1 if the selection condition is met, otherwise set to 0. the

上述的扩展选择因素即载频性能数据和话务量数据对应位的取值可以根据权重算法确定。为了体现性能和话务量水平同等的重要性,将载频性能数据和话务量数据按照级别划分为相同的M个等级,该M是设定的值,例如可以是五。例如对载频的话务量指标由低到高划分1~5五个等级,对载频的性能指标由好到差划分1~5五个等级,其中话务量最高的载频等级为5,性能数据最好的载频等级为1,性能数据最差的载频等级为5,话务量最低的载频等级为1。然后,再对所述每个扩展因素分别赋予一个权重值,各个扩展因素的权重值的和值为1。例如对于上述的性能数据和话务量数据分别赋予一个权重值,例如话务量数据的权重值为0.4,载频数据的权重值为0.6。最后根据以下公式(1)确定下电权值中扩展选择因素对应位数的取值:性能指标等级×性能权重+(M+1-话务量指标等级)×话务量权重。(1)  The values of the above-mentioned extended selection factors, that is, the corresponding bits of the carrier frequency performance data and the traffic data, can be determined according to a weighting algorithm. In order to reflect the equal importance of performance and traffic level, the carrier frequency performance data and traffic data are divided into the same M levels according to levels, where M is a set value, for example, five. For example, the traffic volume index of the carrier frequency is divided into five grades from low to high, and the performance index of the carrier frequency is divided into five grades from 1 to 5, among which the carrier frequency grade with the highest traffic volume is 5 , the carrier frequency class with the best performance data is 1, the carrier frequency class with the worst performance data is 5, and the carrier frequency class with the lowest traffic volume is 1. Then, a weight value is assigned to each expansion factor, and the sum of the weight values of each expansion factor is 1. For example, a weight value is assigned to the above-mentioned performance data and traffic data, for example, the weight value of traffic data is 0.4, and the weight value of carrier frequency data is 0.6. Finally, according to the following formula (1), the value of the number of digits corresponding to the extended selection factor in the power-off weight is determined: performance index level×performance weight+(M+1-traffic index level)×traffic weight. (1)

比如,某个载频的话务量级别为1,权重为0.4,载频性能级别为5,权  重为0.6,那么扩展选择因素对应位的取值是5*0.6+(6-1)*0.4=5,如果该扩展选择因素对应的是下电权值的后四位,则具体取值为0101。另外,下电权值的位数可以根据实际需要再进行扩充,例如也可以是16位,多余的位可以作为扩展位置空,但是所述选择因素根据优先级的顺序依次对应下电权值中由高到低的位。  For example, the traffic level of a certain carrier frequency is 1, the weight is 0.4, the carrier frequency performance level is 5, and the weight The weight is 0.6, then the value of the corresponding bit of the extended selection factor is 5*0.6+(6-1)*0.4=5, if the extended selection factor corresponds to the last four digits of the power-off weight, the specific value is 0101. In addition, the number of digits of the power-off weight can be expanded according to actual needs, for example, it can also be 16 bits, and the extra digits can be used as expansion positions to be empty, but the selection factors correspond to the power-off weight according to the order of priority. Bits from high to low. the

  空闲 idle   第八位 eighth place   非BCCH载频为1,否则为0 Non-BCCH carrier frequency is 1, otherwise it is 0   第七位 Seventh place   第一子小区为1,否则为0 The first sub-cell is 1, otherwise it is 0   第六位 sixth place   剩余载频中有CS和PS信道时为1,否则为0 1 when there are CS and PS channels in the remaining carrier frequency, otherwise 0   第五位 fifth place   性能指标等级×性能权重+  (M+1-话务量指标等级)×话务量权重 Performance index level × performance weight + (M+1-traffic index level) × traffic weight   后四位 last four digits

                     表1  Table 1

表1中,下电权值的最高位即第八位为空闲,是用于以后新增必要选择因素时预留的位;第七位对应必要选择因素a),当为非BCCH信道时将该位置1,否则置0;第六位对应必要选择因素b),当为第一小区时将该位置1,否则置0;第五位对应必要选择因素c),当剩余载频中有CS和PS信道是将该位置1,否则置0;后四位对应扩展选择因素d)和e),根据公式(1)确定其取值。  In Table 1, the highest bit of the power-off weight value, that is, the eighth bit, is idle, and is reserved for adding a necessary selection factor in the future; the seventh bit corresponds to the necessary selection factor a), and when it is a non-BCCH channel, it will This position is 1, otherwise it is set to 0; the sixth bit corresponds to the necessary selection factor b), when it is the first cell, this position is set to 1, otherwise it is set to 0; the fifth bit corresponds to the necessary selection factor c), when there is CS in the remaining carrier frequency and PS channel, this bit is set to 1, otherwise it is set to 0; the last four bits correspond to expansion selection factors d) and e), and their values are determined according to formula (1). the

BSC根据上述表1将小区内的所有载频(可用载频数必须大于等于2)的下电权值计算出来,将权值最大的载频进行下电。通过本发明的上述方法,BSC很容易地挑选出了需要下电的载频。  The BSC calculates the power-off weights of all carrier frequencies (the number of available carrier frequencies must be greater than or equal to 2) in the cell according to the above Table 1, and powers off the carrier frequency with the largest weight. Through the above method of the present invention, the BSC can easily select the carrier frequency that needs to be powered off. the

另外,本发明在选择下电载频前,还可以进一步包括:统计当前小区的话务量,判断统计的话务量是否达到预设的下电门限值并且当前小区内可用的载频数目大于等于2,如果是则选择下电载频并进行下电;否则,不选择下电载频更不会进行下电。  In addition, before selecting the power-off carrier frequency, the present invention may further include: counting the traffic volume of the current cell, judging whether the statistical traffic volume reaches the preset power-off threshold value and the number of available carrier frequencies in the current cell Greater than or equal to 2, if it is, select the power-off carrier frequency and power off; otherwise, do not select the power-down carrier frequency and will not power off. the

图1为本发明所述选择下电载频的一个具体实施例的流程图。本实施例是在当前小区的话务量统计值当达到下电门限值、且小区内可用载频数目大  于等于2时执行的,并且采用载频掉话率作为性能指标,载频的信道占用比作为话务量指标,各个载频的下电权值为八位的二进制数,且各位的取值说明为表1所述。参见图1,该流程包括:  FIG. 1 is a flowchart of a specific embodiment of selecting a power-down carrier frequency according to the present invention. In this embodiment, when the traffic statistics of the current cell reach the power-off threshold and the number of available carrier frequencies in the cell is large It is executed when it is equal to 2, and the call drop rate of the carrier frequency is used as the performance index, the channel occupancy ratio of the carrier frequency is used as the traffic index, the power-off weight of each carrier frequency is an eight-bit binary number, and the value of each bit The description is as described in Table 1. See Figure 1, the process includes:

步骤101、轮循查询当前小区中的每个载频(可用载频数大于等于2)的信道属性信息,初始化每个载频的下电权值为0;将第一个载频作为当前载频。  Step 101, query the channel attribute information of each carrier frequency (the number of available carrier frequencies is greater than or equal to 2) in the current cell in round robin, initialize the power-off weight value of each carrier frequency to 0; use the first carrier frequency as the current carrier frequency . the

步骤102、判断当前载频是否为非BCCH载频,即当前载频的信道是否为非BCCH,如果是,则将当前载频下电权值的第七位置1,否则将当前载频下电权值的第七位置0。  Step 102, determine whether the current carrier frequency is a non-BCCH carrier frequency, that is, whether the channel of the current carrier frequency is a non-BCCH, if yes, then set the seventh position of the current carrier frequency power-off weight value to 1, otherwise power off the current carrier frequency The seventh position of the weight is 0. the

步骤103、判断当前载频是否属于当前小区的第一子小区,如果是,则将当前载频下电权值的第六位置1;否则将当前载频下电权值的第六位置0。  Step 103: Determine whether the current carrier frequency belongs to the first sub-cell of the current cell, and if so, set the sixth position of the current carrier frequency power-off weight to 1; otherwise, set the sixth position of the current carrier frequency power-off weight to 0. the

步骤104、判断当前小区内除当前载频外的剩余载频中是否有CS信道和PS信道,如果是则将当前载频下电权值的第五位置1,否则将当前载频下电权值的第五位置0。  Step 104. Determine whether there are CS channels and PS channels in the remaining carrier frequencies in the current cell except the current carrier frequency. If yes, set the fifth position of the current carrier frequency power-off weight value to 1, otherwise set the current carrier frequency power-off weight value to 1. The fifth position of the value is 0. the

步骤105、将掉话率按照0~2%、2%~5%、5%~10%、10%~15%、15%~100%,分成1~5级,载频的信道占用比按照20%一个分级分成1~5级∶1∶0~20%,...,5∶80%~100%,根据所述划分的等级,确定当前载频的性能指标等级和话务量指标等级;然后按照以下公式确定当前载频下电权值后四位的取值:  Step 105, the call drop rate is divided into 1-5 levels according to 0-2%, 2%-5%, 5%-10%, 10%-15%, 15%-100%, and the channel occupancy ratio of the carrier frequency is according to 20% is divided into 1 to 5 grades: 1: 0 to 20%, ..., 5: 80% to 100%, according to the grades of the division, determine the performance index level and traffic index level of the current carrier frequency ; Then determine the value of the last four digits of the current carrier frequency power-off weight according to the following formula:

性能指标等级×性能权重+(6-话务量指标等级)×话务量权重  Performance index level × performance weight + (6-traffic index level) × traffic weight

比如,某个载频的话务量级别为1,权重为0.4,载频性能级别为5,权重为0.6,那么扩展选择因素对应位的取值是5*0.6+(6-1)*0.4=5,如果该扩展选择因素对应的是下电权值的后四位,则具体取值为0101。  For example, if the traffic level of a carrier frequency is 1, the weight is 0.4, the carrier frequency performance level is 5, and the weight is 0.6, then the value of the bit corresponding to the expansion selection factor is 5*0.6+(6-1)*0.4 =5, if the extended selection factor corresponds to the last four digits of the power-off weight, the specific value is 0101. the

步骤106、判断是否轮询完毕当前小区内所有的载频,如果是则执行步骤107,否则,将下一载频作为当前载频,返回步骤102。  Step 106 , judging whether all the carrier frequencies in the current cell have been polled, if so, execute step 107 , otherwise, use the next carrier frequency as the current carrier frequency, and return to step 102 . the

步骤107、比较当前小区内的各个载频的下电权值,选择下电权值最大的载频置下电标志;并通知BTS将该载频进行下电。  Step 107: Compare the power-off weights of the various carrier frequencies in the current cell, select the carrier frequency with the largest power-off weight and set the power-off flag; and notify the BTS to power off the carrier frequency. the
