Abstract
一种跨制式动态功率资源分享的方法及装置，所述跨制式动态功率资源共享的方法包括：检测移动通信系统的载波使用情况；若所述移动通信系统的载波为预设闲置载波，则将所述移动通信系统闲置的功率资源共享给其他移动通信系统；若所述移动通信系统的载波为预设业务载波，则将所述移动通信系统使用的功率资源进行回收配置。
Description
本发明实施例涉及但不限于移动通信技术领域，尤其涉及一种跨制式动态功率资源分享的方法及装置。
相关技术中，针对于多个移动通信系统中的载波功率分配情况，即多制式多模场景下的功率分配，采用的是最简单的策略：在小区建立完成后就将多种制式的可用功率配置给RRU(Radio Remote Unit射频拉远单元)。例如，在GSM(全球移动通信系统)制式下，每个载波的发射功率是固定的，一旦载波个数确定，GSM可使用的总功率也随之固定。在LTE(Long Term Evolution，长期演进)制式下，每个通道的发射功率也是固定的，通道个数确定后，LTE的可用的总发射功率也随之确定。在不修改参数的情况下，每个制式的可用功率不会发生变化。
因此，在相关技术中，当一制式业务负荷很少或者没有业务的时候，其相应的功率资源就被闲置，而且这些被闲置的功率资源也不能及时调配给其他制式使用，这样既造成了功率资源浪费，也无法有效提高重负荷业务制式的容量。

其中，检测所述移动通信系统的载波用户记录情况或检测所述移动通信系统的载波闲置率情况；例如，在GSM系统中，是通过检测该系统的载波用户记录情况来检测其载波使用情况的，包括：在移动通信系统中的每个载波上建立一个用户记录，用于记录载波所承载TCH(业务信道)信道上的用户；每增加或者减少一个用户，维护一次记录。即对系统中的每个载波的用户记录进行检测就是对移动通信系统的载波进行的检测；而在LTE系统中，是通过检测系统的载波闲置率情况来检测其载波的使用情况的，包括：检测系统中当前已使用的子载波资源信息；再根据系统本身能够提供的总的可用子载波资源信息来计算得到当前系统中的载波闲置率；对于其他移动系统可以根据其自身载波的特点来对应检测其载波的使用情况，在此不再累述。
S102：根据检测结果判断所述移动通信系统的载波是否为预设空闲载波；若是，则转S103；若否，则转S104；
所述预设闲置载波可以包括：空闲载波、载波使用率较低的系统中的载波等；例如，在GSM系统中，根据步骤S101中的检测GSM系统的载波用户记录情况，若检测到一个载波上的用户记录为空，且超过预设时间，则判断所述用户记录为空对应的载波为预设闲置载波。包括：若一个载波的用户记录为空的时间超过时间门限T，则标记该载波为预设闲置载波，并将其进行下电处理；在LTE系统中，根据步骤S101中的检测LTE系统的载波闲置率情况，若检测到该系统中的载波闲置率高于阈值，则判断该系统的载波为预设闲置载波；包括：若当前检测系统的载波闲置率高于阈值，则对系统中的载波发射功率进行限制，以方便其闲置功率资源对外进行分享。
S103：将所述移动通信系统闲置的功率资源的共享给其他移动通信系统；
包括：将功率资源共享消息向所述其他移动通信系统进行发送；或者，向外部服务器发送功率资源消息；再由所述外部服务器向所述其他移动通信系统转达所述功率资源消息。在本实施例中，所述功率资源消息可以为大于零的闲置功率值或者按照预设的二进制规则将其功率非零的情况告诉给其他移动通信系统；在本实施例中，在将所述功率资源消息发送给所述外部服务器后，所述外部服务器可以对所述移动通信系统闲置的功率资源进行保存，这样，在对功率资源向其他移动终端进行配置时会更加方便。
S104：判断所述移动通信系统的载波是否为预设业务载波；若是，则转S105；若否，则转S101；
所述预设业务载波包括：由空闲载波转化为业务载波的载波，或者，有载波闲置率高转化为载波闲置率低的载波等；其中，对应步骤S101中的检测GSM系统中的载波用户记录情况，若一个载波存在业务请求消息，且该载波在上一时刻为预设闲置载波，则判断该载波为由空闲载波转化为业务载波，即为所述预设业务载波，则此时需要向外发送功率资源回收请求消息；对应步骤S101中的检测LTE系统的载波闲置率情况，若检测到所述LTE系统的载波闲置率低于阈值，且在上一时刻，所述LTE系统的载波闲置率高于所述阈值，则此时该系统的载波为预设业务载波，需要取消其载波发射功率的限
制。
S105：将所述移动通信系统使用的功率资源进行回收配置。
包括：将功率资源回收请求消息对外发送，并在接收到响应消息后，将所述移动通信系统使用的功率资源进行回收配置。所述将功率资源回收请求消息对外发送包括：直接将所述功率资源回收请求消息向共享该功率资源的其他移动通信系统进行发送；或者，向外部服务器发送所述功率资源回收请求消息，再由所述外部服务器将所述功率资源回收请求消息转达给共享该功率资源的其他移动通信系统。在本实施例中，所述功率资源回收请求消息为小于零的闲置功率值或者按照预设的二进制规则将其功率零可用的情况告诉给共享其载波功率资源的移动通信系统；所述将该移动通信系统使用的功率资源进行回收配置包括：将移动通信系统上载波的功率资源进行重新配置，恢复其正常运行时的功率状态。
如图2所示为本发明实施例二提供的跨制式动态功率资源分享的方法的流程图，请参见图2，该方法包括：
S201：接收关于其他移动通信系统的载波的功率资源消息；
其中，接收外部服务器转发的关于其他移动通信系统的载波的功率资源消息；或者，接收外部移动通信系统发送的关于其载波情况的功率资源消息。所述功率资源消息包括：功率资源共享消息或功率资源回收请求消息。
S202：判断所述功率资源消息是否为功率资源共享消息，若是，则转S203；若否，则转S204；
例如，可以通过判断所述功率资源消息是否为大于零的闲置功率值，则判断所述功率资源消息为功率资源共享消息。
S203：将所述功率资源消息对应的功率资源在移动通信系统的载波上进行配置；
将所述功率资源消息对应的功率资源按照所述移动通信系统的用户优先级依次分配到优先级从高到低的用户对应的载波上。例如，在LTE系统中，在接收到所述功率资源消息后，对每个调度时隙都从有业务的用户中筛选出
使用QPSK(Quadrature Phase Shift Keying正交相移键控)的载波，按照一定的优先级，在不超过发射功率上限的情况下，依次增加每个用户对应的载波的发射功率，这样，能够使得用户的通信能力增强，且其通信效果得到提高。
S204：判断所述功率资源消息是否为功率资源回收请求消息，若是，则转S205；若否，则结束；
例如，可以通过判断所述功率资源消息是否为小于零的闲置功率值，则判断所述功率资源消息为功率资源回收请求消息。
S205：停止移动通信系统中共享的功率资源，并向所述其他移动通信系统反馈响应消息。
向所述其他移动通信系统反馈响应消息包括：向外部服务器反馈响应消息，所述响应消息用于外部服务器转达给所述其他移动通信系统；或者，直接向所述其他移动通信系统反馈响应消息，这样，当其他移动通信系统接收到该响应消息后，就能快速地恢复其对应载波的发送功率。
如图3所示，为本发明实施例三提供的在GSM和LTE两个系统间的跨制式动态功率资源分享的方法的流程图，在本实施例中，GSM系统作为存在闲置功率资源的系统，LTE系统作为接收共享功率资源，并将共享功率资源在其系统中进行配置的系统；过程包括：
S301：GSM在检测到有空闲载波时，会对相应载波进行下电处理，回收闲置的功率资源；
GSM信道可以划分为控制信道和TCH信道两大类，其中，TCH信道是专门提供给用户做语音以及2G数据业务传送，而TCH信道可以灵活配置到不同GSM载波上。那么在语音以及2G数据业务较少的时间段，会有一些载波空闲，因此，在进行GSM的载波检测时，若发现空闲载波，则可以对该空闲载波上的功率资源进行利用。
S302：GSM将其回收的闲置功率资源的消息通知LTE；
S303：LTE将所述闲置的功率资源重新进行配置；
这样，可以增加LTE的可用功率。在LTE系统中，LTE的调制方式分为
64QAM(Quadrature Amplitude Modulation，相正交振幅调制)，16QAM(Quadrature Amplitude Modulation正交幅度调制)以及QPSK。其中，64QAM和16QAM方式均涉及到幅度调制，幅度被调制意味着不能随便增加发射功率，会造成星座图畸变，导致终端无法正确解调。而QPSK方式属于相位调制，对幅度并不敏感，也就是说可以增加发射功率。那么，由GSM共享过来的功率就能运用到QPSK调制方式上，可同时在解调参考符号和业务符号上同时加载，达到提高信号质量，增加LTE小区系统容量的目的。
S304：当GSM检测到有用户接入系统时，需要对空闲载波上电，则在对所述空闲载波进行上电之前则需要将其共享的功率资源收回请求消息通知LTE；
S305：LTE将共享部分的功率资源返还给GSM，并向GSM发送响应消息，同时LTE要停止该共享的功率资源的使用，以避免RRU功率过载。
