network resource status acquiring uplink radio cell may be a variety of ways, for example, obtained according to the received message acquisition or active detection. 而上行无线网络资源包括下述至少一种: 小区的功率负载、小区的信道单元占用率、所有以该小区为服务小区的用户的实际传输速率和指配的最高比特速率的比例等。 And the uplink radio resource network comprises at least one of: a power load cell, channel occupancy unit cell, the proportion of all cells in a serving cell for the user's actual transmission rate and the assigned bit rate is the highest. 这里的主动检测过程,可以有多种方式,比如通过预先设置的检测周期,按照所述检测周期对小区的上行无线资源状况进行检测。 Here active detection process, there may be a variety of ways, for example, according to the detection of the uplink radio resources of the cell cycle condition is detected by the detection period set in advance. 步骤S102:根据获取的小区的上行无线网络资源状况调整HARQ重传次数。 The step S102: The number of HARQ retransmissions to adjust the uplink radio network resource status acquisition cell. 其中,对当前HARQ重传次数进行调整,可以有多种方式: 如在需要提高当前HARQ重传次数时,可以将该当前HARQ重传次数调整为预先设置的HARQ重传次数上限值,即高重传目标值;或者,根据预先设置的调整步长,向上调整当前HARQ重传次数;或者,在当前HARQ重传次数为预先设置的HARQ重传次数下限值,即低重传目标值时,将当前HARQ重传次数调整为预先设置的HARQ重传次数上限值,即高重传目标值;或者,在当前HARQ重传次数小于预先设置的HARQ重传次数上限值,即高重传目标值时, 根据预先设置的调整步长,向上调整当前HARQ重传次数。 Wherein the current number of HARQ retransmissions is adjusted, there may be a variety of ways: as need to improve the current number of HARQ retransmissions, the current may be adjusted number of HARQ retransmissions for the HARQ retransmissions preset upper limit number of times, i.e., high retransmission target; or, according to the preset adjustment step size, an upward adjustment of the current number of HARQ retransmissions; or, in the current HARQ retransmission number of times set in advance the number of HARQ retransmissions lower limit, i.e. the retransmission target low when the current number of HARQ retransmission adjusting the number of HARQ retransmissions preset limit, i.e., high target retransmission; or, in the current HARQ retransmission number is smaller than the upper limit set in advance the number of HARQ retransmissions, i.e. high retransmission target, according to the preset adjustment step size, an upward adjustment of the current number of HARQ retransmissions. 如在需要降低当前HARQ重传次数时,可以将当前HARQ重传次数调整为预先设置的HARQ重传次数下限值,即低重传目标值;或者,根据预先设置的调整步长,向下调整当前HARQ重传次数;或者,在当前HARQ重传次数为预先设置的HARQ重传次数上限值,即高重传目标值时,将当前HARQ重传次数调整为预先设置的HARQ重传次数下限值,即低重传目标值;或者,在当前HARQ重传次数大于预先设置的HARQ重传次数下卩艮值,即低重传目标值时, 根据预先设置的调整步长,向下调整当前HARQ重传次数。 The need to reduce the current when the number of HARQ retransmissions, the current may be adjusted to a number of HARQ retransmissions of HARQ retransmissions preset lower limit frequency, i.e. low target retransmission; or, according to the preset adjustment step down adjust the current number of HARQ retransmissions; or, in the current number of HARQ retransmissions of HARQ retransmissions previously set upper limit number of times, i.e., high target retransmission, HARQ retransmission number of the current HARQ adjusted to the preset number of retransmissions lower limit, i.e., low target retransmission;

step S202: determining whether the power load is less than a preset uplink adaptive retransmission threshold power load congestion is removed, if the cell power load is less than a preset uplink adaptive retransmission threshold power load congestion is removed, then step S203; step S203: determining whether the number of HARQ retransmissions target retransmission is high, if the retransmission target is high then step S204; step S204: high retransmission target adjustment target retransmission is low. 在小区的功率负载较低的情况下,降低当前HARQ重传次数值,能够有助于提高业务的最大有效速率,因为业务的最大有效速率为MBR/(l+平均重传次数),使用低重传的时候比使用高重传的时候得最大有效速率肯定能够提高一些, 有效地利用空口负载资源,当小区的功率负载低的时候,这里将当前HARQ重传次数置于预先设置的低重传目标值。 At lower cell power load, reducing the effective rate of the maximum HARQ retransmission number of times this can contribute to improve the business, because of the maximum effective rate traffic MBR / (l + average number of retransmissions), the use of low weight transmission time than using a retransmission time have maximum effective rate is certainly possible to improve some of the efficient utilization of the air interface load of resources, when low cell power loads, where the current HARQ retransmission number into the low retransmission set in advance target value. 当小区的功率负载小于上行自适应重传功率负载拥塞门限时,小区的功率负载处于不拥塞状态,这里将当前HARQ重传次数置于一个低重传目标值时,该低重传目标值为HSUPA业务的QoS控制目标值,通过这种调整不会引起CE拥塞。 When the cell is less than the power load adaptive retransmission uplink congestion threshold power load, the power load in the cell is not congested state, where the current number of HARQ retransmission retransmission placed a low target value, the target value of the retransmission is low QoS HSUPA traffic control target value, this adjustment will not cause congestion CE. 这里的调整方法,也不限于上述方式实现,如在降低当前HARQ重传次数中可以将当前HARQ重传次数调整为预先设置的HARQ重传次数下限值,即低重传目标值;或者,根据预先设置的调整步长,向下调整当前HARQ重传次数;或者,在当前HARQ重传次数为预先设置的HARQ重传次数上限值,即高重传目标值时,将当前HARQ重传次数调整为预先设置的HARQ重传次数下限值,即低重传目标值;或者,在当前HARQ 重传次数大于预先设置的HARQ重传次数下限值,即低重传目标值时,根据预先设置的调整步长,向下调整所述当前HARQ重传次数。 Adjusting method here is not limited to the above-described manner, as in the reduction of the current number of HARQ retransmissions may be adjusted current HARQ retransmission number of the HARQ retransmissions preset lower limit frequency, i.e. low target retransmission; or the adjustment step size is set in advance, down to adjust the current number of HARQ retransmissions; or, in the current HARQ retransmission count upper limit value preset HARQ retransmission number of times, i.e., high target retransmission, HARQ retransmission of the current adjusting the number of the preset number of HARQ retransmission limit, i.e. low target retransmission; Alternatively, when the number of retransmissions lower limit value in the current HARQ retransmission number is greater than the preset HARQ, retransmission i.e. low target value, in accordance with adjust the step size is set in advance, the downward adjustment of the current number of HARQ retransmissions. 图3中示出了本发明实施例中的自适应调整重传次数方法的第二具体流程图,根据获取的小区的功率负载和小区的信道单元占用率调整当前HARQ重传次数,包括:步骤S301:获取小区的功率负载和小区的信道单元占用率;步骤S302:判断所述功率负载是否不大于预设的上行自适应重传功率负载拥塞门限,如果是则进行步骤S303;步骤S303:判断所述信道单元占用率是否大于预设的上行自适应重传信道单元资源拥塞门限,如果是则进行步骤S304;需要说明的是步骤S302和步骤S303是不分先后的,在同时满足所述功率负载是否不大于预设的上行自适应重传功率负载拥塞门限,且所述信道单元占用率是否大于预设的上行自适应重传信道单元资源拥塞门限情况下才进行步骤S304。 FIG. 3 shows a detailed flowchart of the present invention is a second method of adjusting the number of adaptive retransmission in the embodiment, to adjust the current number of HARQ retransmissions, comprising a channel unit and the occupancy load cell power acquired cell: step S301: Get power load cell and a channel unit cell occupancy; step S302: determining whether the power load is not greater than the preset adaptive retransmission uplink power load congestion threshold, S303 is performed if step; step S303: Analyzing the channel unit is greater than a predetermined occupancy rate uplink channel adaptive retransmission unit resource congestion threshold, and if step S304 is performed; should be noted that step S302 and step S303 are the alphabetical order, while satisfying the power before step S304 is not greater than a predetermined load adaptive power loading retransmission uplink congestion threshold, and if the channel element occupancy rate is greater than the limit case where an uplink channel adaptive retransmission resource congestion door unit. 步骤S304:判断HARQ重传次数是否为大于预先设置的HARQ下限值, 如果大于则进行步骤S305;步骤S305:预先设置的调整步长,向下调整所述当前HARQ重传次数。 Step S304: determining whether the number of HARQ retransmissions for the HARQ is greater than the lower limit value set in advance, step S305 is performed if more than; Step S305: pre-set adjustment step length, downward adjustment of the current number of HARQ retransmissions. 需要说明的是,当小区的功率负载高于上行自适应重传功率负载拥塞门限时,则该小区的功率负载处于拥塞状态;当小区的CE占用率高于上行自适应重传CE资源拥塞门限时,则该CE处于紧缺状态。 Incidentally, when the cell power load is higher than the uplink adaptive retransmission the congestion threshold power load, the power load cell is in a congested state; CE when the occupancy rate of the cell in the uplink adaptive retransmission resource congestion door CE limit, the CE is in short supply. 在CE资源处于拥塞状态,且小区的功率负载未处于拥塞状态时,降低HARQ重传次数值能有助于提高CE 利用率,可以提高小区吞吐率。 When CE resources in a congested state, and the power load cell is not in a congested state, reducing the value of the number of HARQ retransmissions can help improve efficiency CE, the cell throughput can be improved. 在将HARQ重传次数值减低之后,会释放基站上的部分空口资源,从而也会释放相应的CE,通过这种设置能够提高CE利用率,提高小区容量。 After reducing the number of times of HARQ retransmissions, an air interface resource release portion at the base station, thereby also releases the corresponding CE, CE can be improved by the utilization of this arrangement, improve the cell capacity. 这里的调整方法,也不限于上述方式实现,如在降低当前HARQ重传次数中可以将当前HARQ重传次数调整为预先设置的HARQ重传次数下限值,即低重传目标值;或者,根据预先设置的调整步长,向下调整所述当前HARQ重传次数;或者,在当前HARQ重传次数为预先设置的HARQ重传次数上限值,即高重传目标值时,将当前HARQ重传次数调整为预先设置的HARQ重传次数下限值,即低重传目标值;或者,在当前HARQ重传次数大于预先设置的HARQ重传次数下限值,即低重传目标值时,根据预先设置的调整步长,向下调整所述当前HARQ重传次数。 Adjusting method here is not limited to the above-described manner, as in the reduction of the current number of HARQ retransmissions may be adjusted current HARQ retransmission number of the HARQ retransmissions preset lower limit frequency, i.e. low target retransmission; or the adjustment step size is set in advance, the downward adjustment of the current number of HARQ retransmissions; or when, in the current number of HARQ retransmissions of HARQ retransmissions previously set upper limit number of times, i.e., high target retransmission, the current HARQ Alternatively, when the number of retransmissions lower limit value in the current HARQ retransmission number is greater than the preset HARQ, retransmissions i.e. low target; the number of retransmissions is adjusted to the preset number of HARQ retransmission limit, i.e. low retransmission target the adjustment step size is set in advance, the downward adjustment of the current number of HARQ retransmissions. 如果在信道单元占用率不大于预设的上行自适应重传信道单元资源拥塞门限情况下时,其对当前HARQ重传次数进行调整的方式可以参考图2所示的流程。 If the limit in the case of channel elements is not greater than a predetermined occupancy rate uplink channel adaptive retransmission resource congestion door unit, in a manner of the current number of HARQ retransmissions may be adjusted with reference to the flow shown in FIG. 图4中示出了本发明实施例中的自适应调整重传次数方法的第三具体流程图,根据获取的小区的功率负载、小区的信道单元占用率和所有以该小区为服务小区的用户的实际传输速率和所指配的最高比特速率的比例调整HARQ重传次数,包括:步骤S401:获取小区的功率负载、小区的信道单元占用率、所有以该小区为服务小区的用户的实际传输速率和所指配的最高比特速率的比例;步骤S402:判断所述功率负载是否大于预设的上行自适应重传功率负载拥塞门限,如果是则进行步骤S403;步骤S403:判断所述信道单元占用率是否小于预设的上行自适应重传信道单元资源拥塞解除门限,如果是则进行步骤S404;步骤S404:判断所有以该小区为服务小区的用户的实际传输速率和所指配的最高比特速率的比例是否小于预设的速率比例门限,如果是则进行步骤S405;需要说明的是步骤S40 Figure 4 shows a detailed flowchart of a third embodiment of the adaptive embodiment of the present invention is a method to adjust the number of retransmissions, according to the power load of the cell acquired, the channel unit and the occupancy rate of all users in the cell to the cell as the serving cell the proportion of the highest bit rate of the actual transmission rate and the assigned adjustment HARQ retransmission times, comprising: step S401: obtaining cell power load, the channel unit occupancy cell, actual transmission for all users in the cell as the serving cell the highest bit rate ratio of the rate and the assigned; step S402: adaptively determining an uplink power load is greater than the predetermined retransmission power load congestion threshold, S403 is performed if step; step S403: determining the channel element occupancy rate is less than a preset uplink channel adaptive retransmission threshold unit resource congestion is removed, S404 is performed if step; step S404: determining the actual maximum bit rate and the assigned transmission for all users in the cell as the serving cell ratio rate is less than a preset speed ratio threshold, if step S405 is performed;
