本发明提供了一种功率控制方法、 设备和系统。 为了更好的理解本发 明的技术方案， 下面结合附图对本发明提供的实施例进行详细地描述。
参见图 1 , 图 1是本发明一实施例提供的功率控制方法的流程图。
在本发明实施例中， 第一制式通信系统和第二制式通信系统共存， 且 第一制式通信系统和第二制式通信系统所使用的频谱资源之间的保护带宽 不够。 第一制式通信系统和第二制式通信系统的网络制式不同， 例如， 第 一制式通信系统为 GSM系统， 第二制式通信系统为 UMTS 系统， 或者， 第一制式通信系统为 GSM系统， 第二制式通信系统为 LTE系统， 都不影 响本实施例的实现。 本发明一实施例提供的功率控制方法包括：
101 , 当在第一制式通信系统进行业务时， 确定第一制式通信系统基站 的发射功率 PI。
当第一制式通信系统内进行业务时， 例如， 可以是当用户设备（User Equipment, 筒称 UE )在第一制式通信系统发起业务时， 或者是， 该业务切 换到第一制式通信系统时， 针对该业务确定第一制式通信系统基站的发射 功率 Pl。 例如， 功率控制设备根据终端上报的测量报告， 结合相应的功控 算法进行功控判决确定基站的发射功率。
102, 确定发射功率 P1 大于或等于第一制式通信系统对第二制式通信 系统干扰门限值 P2。
由于第一制式通信系统和第二制式通信系统所使用的频谱范围可以是 由运营商预先设定的， 因此可以根据两个系统所使用的频谱资源确定会产 生干扰的频点。 并且， 可以根据链路性能确定第一制式通信系统对第二制 式通信系统干扰门限值 P2。
具体的， 可以是首先判断发射功率 P1是否大于或等于第一制式通信系 统对第二制式通信系统干扰门限值 P2, 当判断的结果为是， 则可以确定发 射功率 P1 大于或等于第一制式通信系统对第二制式通信系统干扰门限值 P2。 具体的， 比较 101中的发射功率 P1和干扰门限值 P2的大小， 两个数 值之间的比较可以通过现有技术进行， 当确定发射功率 P1大于第一制式通 信系统对第二制式通信系统干扰门限值 P2时， 执行 103。 当确定发射功率 P1小于第一制式通信系统对第二制式通信系统干扰门限值 P2时，执行 104。
103, 在干扰频点上使用小于 P1 的功率发送数据， 干扰频点为该业务 使用的跳频频点中对第二制式通信系统产生干扰的频点。
例如， 当在第一制式通信系统进行业务时， 第一制式通信系统会分配 该业务使用的跳频频点， 这些跳频频点组成该业务的跳频集合。 在这些跳 频集合中， 对第二制式通信系统产生干扰的频点为跳频频点。 例如， 可以 设定该业务使用的跳频集合中与第二制式通信系统的中心频点间隔小于一 预设数据的频点为干扰频点， 或者， 也可以认为跳频集合中和第二制式通 信系统占用相同频谱资源的频点为干扰频点。 当确定发射功率 P1大于第一 制式通信系统对第二制式通信系统干扰门限值 P2时， 即可以认为在干扰频 点上以大于 P2的功率 P1发送数据会对第二制式通信系统造成干扰， 第一 制式通信系统在这些干扰频点上使用小于根据终端上报的测量报告 (即反 映无线环境的参数 )及功控算法得出的该业务要使用的发射功率 P1发送数 据。
可选的， 降低在干扰频点的发射功率具体可以在干扰频点使用干扰门 限值 Ρ2的功率发送数据， 或者， 可以根据第一制式通信系统干扰频点下降 功率引起的性能损失和由此对第二制式通信系统的性能增益之间的关系确 定干扰频点的发射功率， 以求得第一和第二制式通信系统的性能损失和增 益的平衡， 或者， 可以通过该业务非干扰频点能补偿的功率确定干扰频点 的发射功率， 以保证该业务的性能， 或者， 也可以从其他保证业务的 QoS 角度等出发确定干扰频点的发射功率， 本发明实施例并不对此进行限定。
104, 在干扰频点和非干扰频点使用 P1功率发送数据。
当确定发射功率 P 1小于预设的第一制式通信系统对第二制式通信系统 干扰门限值 P2 ,干扰频点的发射功率 P1没有达到干扰值不会对第二制式通 信系统造成干扰， 或者， 对第二制式通信系统造成的干扰在预设的可以允 许的范围内， 或者可以忽略， 此时， 在分配给该业务的频点上使用根据终 端上报的测量报告及功控算法得出的该业务要使用的发射功率 P1 发送数 据。 即， 在干扰频点和非干扰频点都使用 P1为功率发送数据。
在本发明实施例提供的功率控制方法中， 在第一制式通信系统业务的 发射功率 P1大于干扰门限 P2时， 在干扰频点以小于 P1的功率发送数据。 可以在判断第一制式通信系统将会对第二制式通信系统产生干扰时， 降低 第一制式通信系统干扰频点的信号发射功率， 从而降低第一制式通信系统 对第二制式通信系统的干扰。 参见图 2, 图 2是本发明另一实施例提供的功率控制方法的流程图。 在本发明实施例中， 以第一制式通信系统为 GSM系统， 第二制式通信 系统为 UMTS系统为例进行详细说明。
201 , 当在第一制式通信系统进行业务时， 确定基站的发射功率 Pl。 其中， 具体的方法可以参见上一实施例的 101。
202, 确定发射功率 P1 大于或等于第一制式通信系统对第二制式通信 系统干扰门限值 P2。
可以理解的是， 在确定第一制式通信系统对第二制式通信系统的干扰 门限值时， 可以考虑以下因素： 当第一制式通信系统的 GSM系统的发射功 率降低到某个值，以减小对作为第二制式通信系统的 UMTS系统的干扰时， 对 UMTS系统的性能增益最大； 以及， 当第一制式通信系统的 GSM系统 的发射功率降低到某个值之前， 对 GSM 系统的性能影响不是 4艮大， 而当 GSM系统的发射功率降低到这个值之后， 对如果继续降低 GSM系统的发 射功率则对 GSM系统的性能影响会明显增大。 在确定干扰门限值 P2时， 可以综合考虑这两方面的因素， 以求得 GSM系统和 UMTS系统整体的性 能增益最大。
203 , 以根据干扰频点上损失的功率和非干扰频点上补偿的功率的关系 确定的干扰频点的发射功率发送数据。
例如， 可以获取第一制式通信系统分配给该业务的跳频集合中与第二 制式通信系统的中心频点间隔小于 W1的跳频频点，确定这些间隔小于 W1 的跳频频点为干扰频点， 其中， W1为第一制式通信系统的载频带宽和第二 制式通信系统的载频带宽的和除以 2的商。 即， Wl= (第一制式通信系统 的载频带宽 +第二制式通信系统的载频带宽） 12。 网络的载频带宽与具体的 网络制式相关，例如第一制式通信系统为 GSM网络，则其载频带宽为 200K, 若第二制式通信系统为 UMTS网络， 则其带宽为 5Mhz。 可以理解的是， 第 二制式通信系统所占用的频带可以是运营商规划好的， 因此， 其中心频点 也是可以预先得知的。
在所确定的干扰频点上根据干扰频点上损失的功率和非干扰频点上补 偿的功率确定干扰频带采用的发射功率。 可以理解的是， 根据协议的规定， 系统规定了每个小区有预定的最大发射功率， 在基站发送数据时的发射功 率最大不超过规定的最大发射功率。 由于当降低干扰频点上的发射功率以 减少对第二制式通信系统的干扰时， 第一制式通信系统可以通过在非干扰 频点上增加功率， 利用其交织增益来弥补干扰频点上降功率导致的性能损 失。
可以理解的是， 由于降低在干扰频点的发射功率时， 需要增加在非干 扰频点上的发射功率来弥补干扰频点上降功率导致的性能损失， 而由于最 大发射功率的限制， 非干扰频点上的发射功率最大可以升至该小区的最大 发射功率。 即， 当需要增加非干扰频点的发射功率来弥补损失时， 每个非 干扰频点上最多可以增加的功率为小区的最大发射功率与确定发射功率 P1 之间的差。 因此， 当确定了干扰频点和非干扰频点的个数之后， 就能够确 定在非干扰频点上最多可以补偿的功率损失。 而在干扰频点上， 干扰频点的发射功率通常最低降到干扰门限（在干 扰频点发射功率降到干扰门限之下继续降功率对第二通信制式系统带来的 增益并不明显， 而对第一制式通信系统的损失较大。）， 即， 干扰频点上发 射功率减小的最大幅度通常为确定发射功率 P1与干扰门限值 P2之间的差。 因此， 当确定了干扰频点和非干扰频点的个数之后， 就能够确定在干扰频 点上可能损失的最大发射功率。
进一步的， 可以通过以下方式来确定干扰频点上的发射功率： 当干扰 频点上功率降至 P2、 非干扰频点上功率升至 Pmax时， 以根据干扰频点上损 失的功率和非干扰频点上补偿的功率的关系确定的干扰频点的发射功率发 送数据， Pmax为业务所在第一制式通信系统小区的最大发射功率。
具体的： 非干扰频点上能补偿的功率为： （小区的最大发射功率 Pmax - 发射功率 PI ) X非干扰频点的数目。 干扰频点上能减小的功率为： （发射功 率 P1-干扰门限值 P2) 干扰频点的数目。 比较非干扰频点上能补偿的功率 和干扰频点上能减小的功率的大小， 当非干扰频点上能补偿的功率能补偿 大于干扰频点上需要减少的功率， 则可以将干扰频点的功率降低至干扰门 限。
采用公式表达即为： 确定（Pmax_ PI ) x nl > ( P1-P2 ) x n2+Poffset, 其 中， nl为非干扰频点的个数， n2为干扰频点的个数， P。ffsst为补偿功率偏置， 为所述业务所在所述第一制式通信系统小区的最大发射功率， P1 为确 定该业务的发射功率， P2为第一制式通信系统对第二制式通信系统干扰门 限值。
具体的， 当确定非干扰频点上能补偿的功率能补偿大于干扰频点上需 要减少的功率， 可以在干扰频点使用干扰门限值 P2功率发送数据。 在非干 扰频点上使用大于发射功率 P1的功率发送数据。
进一步的， 本发明实施例还可以包括：
204, 在非干扰频点上使用大于发射功率 P1的功率发送数据。
例如， 可以是， 根据干扰频点上的发射功率确定非干扰频点的发射功 率发送数据。
由于干扰频点上损失的功率为 (发射功率 P1-干扰门限值 P2) X干扰频点 的数目 n2, 而非干扰频点上需要的补偿功率偏置为 P。ffset, 因此在非干扰频 点上需要增加的功率为 (发射功率 P1-干扰门限值 P2) 干扰频点的数目 n2+ 补偿功率偏置 P。ffset, 由此， 在非干扰频点上， 可以以通过以下公式确定的 非干扰频点的发射功率 P3发送数据： P3=Pl+[ ( PI- P2 ) n2+Poffset ) ]/nl , 其中， P3为确定的非干扰频点的发射功率， nl为非干扰频点的个数， n2为 干扰频点的个数， P。ffset为补偿功率偏置。
或者， 可以以链路性能能够得到补偿为依据， 预先得出在干扰频点上 下降的功率值所对应的在非干扰频点上需要上升的功率值。 即， 得出干扰 频点上下降的功率值和非干扰频点上上升的功率值之间的对应关系。 在具 体方案中， 当确定了某个干扰频点具体的下降功率时通过对应关系可以直 接得出非干扰频点上需要补偿的功率值。 可以理解的是， 可以通过链路性 能仿真、 统计等现有技术的方式得出上述两者之间的关系。
在本发明实施例中， 第一制式通信系统的功率控制设备不仅在干扰频 点上使用小于确定的发射功率 P1的功率向终端发送数据， 还在非干扰频点 上使用大于确定的发射功率 P1的功率向终端发送数据， 因而可以弥补干扰 频点上对该终端带来的功率损失， 从而保证第一网络的终端的正常通信。 当非干扰频点能补偿的功率值超过干扰频点上能降低的功率值时， 第一制 式通信系统根据干扰频点上损失的功率确定非干扰频点的发射功率， 或者 根据干扰频点下降的功率和非干扰频点上升的功率的确定非干扰频点的发 射功率， 在降低对第二制式通信系统的干扰与满足第一制式通信系统的业 务的链路性能之间取得平衡。 本发明再一实施例仍以第一制式通信系统为 GSM系统，第二制式通信 系统为 UMTS系统为例进行详细说明。
当在第一制式通信系统进行业务时， 确定基站的发射功率 Pl。
其中， 具体的方法可以参见图 1对应的实施例的 101。
确定发射功率 P1大于或等于第一制式通信系统对第二制式通信系统干 扰门限值 P2。
根据干扰频点上损失的功率和非干扰频点上能够补偿的功率的关系确 定干扰频点的发射功率发送数据。
当干扰频点上功率降至 P2、 非干扰频点上功率升至 Pmax时， 根据干 扰频点上损失的功率和非干扰频点上能够补偿的功率的关系确定的干扰频 点的发射功率发送数据， Pmax为业务所在第一制式通信系统小区的最大发射 功率。
对非干扰频点上能补偿的功率和干扰频点上能减小的功率可以采用前 面描述的实施例的方式确定。
具体的， 当非干扰频点上能补偿的功率小于非干扰频点上能减小的功 率时， 由于非干扰频点上能补偿的功率小于干扰频点上损失的功率， 当干 扰频点的功率降到门限值时， 即使将非干扰频点的功率上升到小区的最大 发射功率， 第一制式通信系统的该业务的性能也不能得到保证。
因此， 当非干扰频点上能补偿的功率小于非干扰频点上能减小的功率 时， 可以确定将非干扰频点的功率上升到小区的最大发射功率， 再根据非 干扰频点上最大能补偿的功率值确定干扰频点上能够减小的功率值。
例如， 采用公式表达可以是： 确定（Pmax_ PI ) x nl+Poffset < ( P1-P2 ) x n2 , 其中， nl为非干扰频点的个数， n2为干扰频点的个数， P。ffsst为补偿 功率偏置， P1为确定该业务的发射功率， P2为第一制式通信系统对第二制 式通信系统干扰门限值。 此时在非干扰频点以 Pmax功率发送数据。 并可以通 过以下公式确定干扰频点的发射功率 P4发送数据： P4=P1- ( Pmax- PI ) nl /n2 , 其中， Ρ4为确定的干扰频点的发射功率， nl为非干扰频点的个数， n2为干扰频点的个数。 当然， 在根据非干扰频点上增加的功率确定干扰频 点上能减小的功率时， 也可以根据非干扰频点上补偿的功率值和干扰频点 上损失的功率值与链路性能的对应关系直接确定干扰频点上下降的功率 值。 在干扰频点上以所确定该业务的发射功率 P1为基础降低干扰频点上的 功率。
在本发明实施例中， 第一制式通信系统的功率控制设备不仅在干扰频 点上使用小于确定的发射功率 P1的功率向终端发送数据， 还在非干扰频点 上使用大于确定的发射功率 P1的功率向终端发送数据， 因而可以弥补干扰 频点上对该终端带来的功率损失， 从而保证第一网络的终端的正常通信。 当非干扰频点能补偿的功率值小于干扰频点上能降低的功率值时， 第一制 式通信系统根据非干扰频点上能补偿的功率确定干扰频点能损失的功率进 而确定干扰频点的发射功率， 或者根据干扰频点下降的功率和非干扰频点 上升的功率的确定非干扰频点的发射功率， 在降低对第二制式通信系统的 干扰与满足第一制式通信系统的业务的链路性能之间取得平衡。 为对本发明实施例做进一步详细说明，请参见图 3, 图 3是本发明又一 实施例提供的功率控制方法的流程图。
在本方法实施例的应用场景中， 第一制式通信系统为 GSM 网络， 载频 带宽为 200K, 第二制式通信系统为 UMTS网络或长期演进网络 (Long Term Evolution, LTE), 例如， LTE系统的载频带宽可以是 3、 5、 10等， 而 UMTS 系统的载频带宽为 5M。本发明实施例以第二制式通信系统为 UMTS系统为例 来说明。 业务在 GSM系统中发起， 或者切换到 GSM系统中， GSM系统为该业 务分配相应的跳频频点。 在本发明实施例中， 假设分配给该业务的跳频频 点为 {1、 3、 5、 7、 9、 10}, 其对应的频率为 { 935.2、 935.6、 936、 936.4、 936.8、 937 }, 单位为 Mhz, UMTS网络的中心频点为 939.3Mhz。
301, 第一制式通信系统接收终端发送的下行测量报告。
当在第一制式通信系统进行业务（例如， 发起业务或切换） 时， 第一 制式通信系统的功率控制设备接收进行业务的终端发送的测量 ^艮告， 该下 行测量报告携带终端所接受的下行信号的强度和质量以体现该业务所处的 无线环境。
302, 第一制式通信系统根据测量报告确定该业务的下行发射功率 Pl。 具体的第一制式通信系统的功率控制设备根据测量报告确定进行该业 务过程中， （小区）基站的发射功率 P1, 其中具体的计算的方法可以采用现 有技术。 例如， 本发明实施例中确定该业务的下行发射功率 P1为 14W, GSM 网络配置的小区最大发射功率？ 为 20W。
303, 判断发射功率 P1 是否大于或等于第一制式通信系统对第二制式 通信系统的干扰门限功率 P2。
可以理解的是， 第一制式通信系统对第二制式通信系统的干扰门限功 率 P2可以是通过仿真等现有技术确定的。 通过比较发射功率 P1和干扰门 功率 P1超过干扰门限功率 P2时， 确定发射功率 P1超过第一制式通信系统 对第二制式通信系统的干扰门限功率 P2, 执行 304, 当发射功率 P1小于干 扰门限功率 P2时， 确定发射功率 P1 小于第一制式通信系统对第二制式通 信系统的干扰门限功率 P2, 执行 310。 可以意识到的是， 也可以是判断发 射功率 P 1是否超过第一制式通信系统对第二制式通信系统的干扰门限功率 P2。 并不影响本发明实施例的实现。 例如， UMTS 系统根据链路性能、 可接受的吞吐率等参数确定第二制式 通信系统的下行干扰门限功率 P2为 10W。
304, 确定该业务中对第二制式通信系统产生干扰的干扰频点。
例如， GSM 系统的功率控制设备获取该业务的干扰频点。 可知， UMTS 系统的中心频点为 939.3Mhz, 该业务的跳频集合中频点 9、 10与 UMTS网络 的频点间隔分别为 2.5和 2.3, 间隔小于 W3, 其中， W3= ( 0.2+5) /2=2.6。 因此确定在该业务的跳频频点中， 频点 9、 10为干扰频点， 频点 1、 3、 5、
7为非干扰频点。 可以看出， 在本实施例场景下， 该具体业务对第二制式通 信系统的干扰频点数目 n2=2, 非干扰频点数目 nl=4。
305, 判断当干扰频点上功率降至 P2、 非干扰频点上功率升至 Pmax时， 非干扰频点上补偿的功率与补偿功率偏置的和是否大于干扰频点上损失的 功率。
由前面提供的实施例可知， 当干扰频点上功率降至 P2时， 干扰频点上 能减小的功率为： （发射功率 P1-干扰门限值 P2) X干扰频点的数目 n2。 非 干扰频点上能补偿的功率为： （小区的最大发射功率 Pmax-发射功率 P1 ) X非 干扰频点的数目 nl, 补偿功率偏置为 P。ffsst。
采用公式表达即为， 判断 （Pmax_ PI ) xnl > (P1-P2 ) xn2+Poffset, 其 中， nl为非干扰频点的个数， n2为干扰频点的个数， P。ffsst为补偿功率偏置； 其中， Pmax为所述业务所在所述第一制式通信系统小区的最大发射功率， nl 为所述非干扰频点的个数， n2为所述干扰频点的个数， P。ff 为补偿功率偏 置， P1为确定该业务的发射功率， P2为第一制式通信系统对第二制式通信 系统干扰门限值， P。ffS6t为补偿功率偏置。
可以理解的是， 本步骤也可以是判断当干扰频点上功率降至 P2、 非干 扰频点上功率升至 P ^时，非干扰频点上补偿的功率与补偿功率偏置的和是 否大于或等于干扰频点上损失的功率。 本发明对此并不限定。
具体在本实施例场景下，非干扰频点上能补偿的功率： （ Pmax_ PI ) x nl= (20-14) χ 4=24W, 干扰频点上能减小的功率为: (P1-P2) χ n2= ( 14-10) x 2=8, 假设补偿功率偏置 P。ffset=3, (P1-P2) X n2+Poffset =8+3=11, 此时， 由于判断（Pmax_Pl ) xnl > (P1-P2) χ n2+P。ffset的结果成立， 则执行 306。 若根据干扰频点的个数、 非干扰频点的个数、 以及其他参数判断出上述公 式不成立， 则执行 308。 306, 在干扰频点使用干扰门限值 P2功率发送数据。
具体的 GSM系统的功率控制设备控制基站以 P2功率发送该业务的下行 数据。
307, 在非干扰频点上使用大于发射功率 P1的功率发送数据。
由于在干扰频点上降低了发射功率， 因此升高非干扰频点上的发射功 率。
进一步的， 可以根据干扰频点上的发射功率确定非干扰频点的发射功 率发送数据。
例如， 由于干扰频点上损失的功率为（发射功率 P1-干扰门限值 P2) X 干扰频点的数目 n2, 而非干扰频点上需要的补偿功率偏置为 P。ffset, 因此在 非干扰频点上需要增加的功率为（发射功率 P1-干扰门限值 P2) X干扰频点 的数目 n2+补偿功率偏置 P。ffset, 由此， 可以以通过以下公式确定的非干扰 频点的发射功率 P3发送数据： P3=Pl+[ (PI- P2 ) χ n2+Poffset ) ]/nl, 其 中， P3为确定的非干扰频点的发射功率， nl为非干扰频点的个数， n2为干 扰频点的个数， P。ffSet为补偿功率偏置。
具体在本实施例场景中， 可以确定非干扰频点的发射功率 =14+[ ( 14- 10 ) χ 2+3 ) ]/4=16.75。 在本发明实施例中， 可以对计算得到的结果进行 向上取整， 例如 16.75W向上取整的结果为 17W。 当然， 也可以向下取整为 16。
308, 若判断（Pmax_Pl ) nl > ( P1-P2 ) χ n2+P。ffset的不成立， 则在非 干扰频点以小区的最大发射功率 Pmax发送数据。
例如， GSM系统的功率控制设备控制基站以 Pmax功率发送该业务的下行 数据。
309, 根据非干扰频点上最大能补偿的功率值确定干扰频点的发射功 率。
进一步的， 可以通过以下公式确定干扰频点的发射功率 P4发送数据： P4=Pl-[ (Pma- PI ) x nl+Poffset]/n2, 其中， P4为确定的干扰频点的发射功 率， nl为非干扰频点的个数， n2为干扰频点的个数。 当然， 在根据非干扰 频点上增加的功率确定干扰频点上能减小的功率时， 也可以根据非干扰频 点上补偿的功率值和干扰频点上损失的功率值与链路性能的对应关系直接 确定干扰频点上下降的功率值。 在干扰频点上以所确定该业务的发射功率 PI为基础降低干扰频点上的功率。
310, 在干扰频点和非干扰频点使用 P1功率发送数据。
当 303的判断结果为发射功率 P1未超过第一制式通信系统对第二制式 通信系统的干扰门限功率 P2时， 由于不会对第二制式通信系统造成干扰， 或者所造成的干扰在可控的范围， 则在该业务的干扰频点和非干扰频点使 用 P1功率发送数据。
在本发明实施例中， 第一制式通信系统的功率控制设备通过判断非干 扰频点上能补偿的功率与补偿功率偏置之和是否能补偿干扰频点上损失的 功率的判断结果确定业务在干扰频点和非干扰频点上的发射功率。 在保证 第一制式通信系统业务性能的同时减少对第二制式通信系统的干扰。 请参见图 4 , 图 4为本发明一实施例功率控制装置结构示意图。 如图 4 所示， 本发明实施例功率控制装置包括：
第一确定模块 401 , 用于当在第一制式通信系统进行业务时， 确定基站 的发射功率 P1 ;
当第一制式通信系统内进行业务时， 例如， 可以是当用户设备（User Equipment, 筒称 UE )在第一制式通信系统发起业务时， 或者是， 该业务切 换到第一制式通信系统时， 第一确定模块针对该业务确定基站的发射功率 Pl。
第二确定模块 402 , 用于确定发射功率 P1大于或等于第一制式通信系 统对第二制式通信系统干扰门限值 P2;
第二确定模块可以通过比较发射功率 P1和干扰门限值 P2的大小确定 发射功率 P1大于第一制式通信系统对第二制式通信系统干扰门限值 P2 ,当 确定发射功率 P1大于第一制式通信系统对第二制式通信系统干扰门限值 P2 时， 触发第一发送模块执行其操作。
第一发送模块 403 , 用于在干扰频点上使用小于 P1的功率发送数据， 干扰频点为业务使用的跳频频点中对第二制式通信系统产生干扰的频点。
当第二确定模块确定发射功率 P1大于第一制式通信系统对第二制式通 信系统干扰门限值 P2时，即可以认为在干扰频点上以大于 P2的功率 P1发 送数据会对第二制式通信系统造成干扰， 第一制式通信系统在这些干扰频 点上使用小于根据终端上报的测量报告（即反映无线环境的参数）及功控 算法得出的该业务要使用的发射功率 P1发送数据。
作为可选的方案， 第一发送模块降低在干扰频点的发射功率具体可以 在干扰频点使用干扰门限值 P2的功率发送数据， 或者， 可以根据第一制式 通信系统干扰频点下降功率引起的性能损失和由此对第二制式通信系统的 性能增益之间的关系确定干扰频点的发射功率， 以求得第一和第二制式通 信系统的性能损失和增益的平衡， 或者， 可以通过该业务非干扰频点能补 偿的功率确定干扰频点的发射功率， 以保证该业务的性能， 或者， 也可以 从其他保证业务的 QoS 角度等出发确定干扰频点的发射功率， 本发明实施 例并不对此进行限定。
进一步的， 本发明实施例还可以包括：
第三确定模块， 用于确定发射功率 P1小于预设的第一制式通信系统对 第二制式通信系统干扰门限值 P2 ;
第三发送模块， 用于在干扰频点和非干扰频点使用 P1功率发送数据。 在本发明实施例提供的功率控制方法中， 在第二确定模块确定第一制 式通信系统业务的发射功率 P1 大于干扰门限 P2时， 第一发送模块在干扰 频点以小于 P1的功率发送数据。 从而降低第一制式通信系统对第二制式通 信系统的干扰。 请参见图 5 , 图 5为本发明另一实施例功率控制装置结构示意图。如图 5所示， 在本发明实施例功率控制装置包括： 第一确定模块 501 , 第二确定 模块 502 , 第一发送模块 503 , 其具体实现方法可以参见上一实施例。

或者， 第一发送模块， 还可以用于当干扰频点上功率降至 P2、 非干扰 频点上功率升至 时， 以根据干扰频点上损失的功率和非干扰频点上补偿 的功率的关系确定的干扰频点的发射功率发送数据， 为业务所在第一制 式通信系统小区的最大发射功率。
进一步的， 第一发送模块， 可以包括：

第一发送子模块 5032,用于在干扰频点使用干扰门限值 P2功率发送数 据。
更进一步的， 本实施例的装置还可以包括：
第二发送模块， 用于以根据干扰频点上的发射功率确定所的述非干扰 频点的发射功率发送数据。
由于干扰频点上损失的功率为（发射功率 P1-干扰门限值 P2) X干扰频 点的数目 n2, 而非干扰频点上需要的补偿功率偏置为 P。ffset, 因此在非干扰 频点上需要增加的功率为（发射功率 P1-干扰门限值 P2) X干扰频点的数目 n2+补偿功率偏置 P。ffset, 因此， 可选的， 第二发送模块， 可以用于以通过以 下公式确定的非干扰频点的发射功率 P3发送数据： P3=P1+ [ (PI- P2) χ n2+Poffset ) ]/nl, 其中， P3 为确定的非干扰频点的发射功率， nl 为非干扰 频点的个数， n2为干扰频点的个数， P。ffsst为补偿功率偏置。 请参见图 6, 图 6为本发明再一实施例功率控制装置结构实示意图。如 图 6所示， 在本发明实施例功率控制装置包括： 第一确定模块 601, 第二确 定模块 602, 第一发送模块 603, 其具体实现方法可以参见上一实施例。
