技术领域
本申请实施例涉及但不限于通信技术领域，尤其涉及一种跳频频点的共享方法、回收方法、控制器、基站系统及计算机可读存储介质。
背景技术
频谱资源是GSM(全球移动通信系统，Global System for Mobile Communicationn)网络和LTE(长期演进，Long Term Evolution)网络的关键资源，为了减少干扰，GSM网络和LTE网络一般情况下使用各自的专有频谱资源。然而，随着LTE终端用户的不断增加，迫切需要扩充LTE带宽，而提高频谱资源利用率能有效提升系统容量和性能。
GSM网络有部分频点配置在LTE网络的载波发射带宽内，跟LTE网络的频谱资源块交叠，但是系统根据实际的使用需要，在一定区域范围内只允许一种制式同时使用。利用话务的潮汐效应，LTE网络和GSM网络可以共享交叠的频段，但不同时使用，这样可以提高频谱资源的利用率。
跳频技术能够提高GSM网络的抗干扰、抗衰落性能，大大提高通话质量，增强紧密复用的组网能力，增加系统容量，因此在GSM网络中应用广泛。然而现有的频谱共享技术不能很好的支持跳频功能，当跳频载频使用属于共享频谱的频点时，由于跳频系统的复杂性，导致这些跳频频点无法共享给LTE，只能被GSM固定占用，这会使得可共享的频点数大幅减少，导致频谱资源的利用率大幅下降。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
GSM网络有部分频点配置在LTE网络的载波发射带宽内，跟LTE网络的频谱资源块 交叠，但是系统根据实际的使用需要，在一定区域范围内只允许一种制式同时使用。利用话务的潮汐效应，LTE网络和GSM网络可以共享交叠的频段，但不能同时使用，这样可以提高频谱资源的利用率。
请参照图1，图1为一种典型的GSM网络和LTE网络的频谱资源共享配置场景图。LTE网络的专有频谱在中间，GSM网络的专有频谱设置在两侧，重叠部分为共享频谱，GSM和LTE网络均可调度使用，GSM网络优先使用。同时规定只有当GSM网络从靠近LTE网络中心频点开始连续不使用重叠部分频点的时候，LTE网络才能使用。现有的频谱共享技术，是对GSM网络的无线资源分配方式进行修改，优先分配GSM网络的专有频谱，其次是共享频谱，共享频谱内部按照距离LTE网络中心频点由远到近的顺序选频点进行资源分配，从而尽可能空出更多的共享频点，供给LTE网络使用，以提高频谱资源的利用率。
跳频技术能够提高GSM网络的抗干扰、抗衰落性能，大大提高通话质量，增强紧密复用的组网能力，增加系统容量，因此在GSM网络中应用广泛。然而现有的频谱共享技术不能很好的支持跳频功能，当跳频载频使用属于共享频谱的频点时，由于跳频系统的复杂性，导致这些跳频频点无法共享给LTE，只能被GSM固定占用，这会使得可共享的频点数大幅减少，导致频谱资源的利用率大幅下降。
基于此，本申请实施例提供了跳频频点的共享方法、回收方法、控制器、基站系统及存储介质，按照相距LTE网络中心频点由近至远的距离，对跳频系统中的共享频点由低至高地排列优先级；将共享频点分配给跳频系统中的载频；在存在所述符合共享条件的空闲载频的情况下，即比所述空闲载频的共享频点优先级低的共享频点均已共享，将空闲载频的共享频点共享给LTE网络使用；根据业务占用的情况，将共享给LTE网络的共享频点回收至跳频系统。根据本申请实施例提供的方案，可实现将跳频系统中的共享频点共享给LTE网络使用，并能在GSM网络业务繁忙时回收共享频点，既保证了跳频系统的功能，又提高了频谱资源的利用率。
下面结合附图，对本申请实施例作进一步阐述。
第一方面，请参照图2，本申请的一个实施例提供了一种跳频频点的共享方法，其中的一种实施例包括但不限于以下步骤：
步骤S1000，按照相距LTE网络中心频点由近至远的距离，对跳频系统中的共享频点由低至高地排列优先级。
基于GSM网络和LTE网络的频谱资源共享方案中，LTE网络的专有频谱位于中间，GSM网络的专有频谱位于两侧，重叠部分为共享频谱，步骤S1000中将距离LTE网络中心频点较远的频点设置为较高的优先级，目的是通过GSM网络的跳频系统优先使用优先级高的共享频点，由此尽可能将靠近LTE网络专有频谱的共享频点释放出来，以供给LTE网络使用，从而实现提高频谱资源的利用率。
步骤S2000，将共享频点分配给跳频系统中的载频。
在步骤S2000的一实施例中，将共享频点分配给跳频系统中的载频包括：共享频点按照由低至高的优先级顺序，对应分配给移动分配偏移量MAIO由大到小的载频。MAIO(移动分配偏移量，mobile Allocation Indication Offset)用于确定起跳频点，使用MAIO目的是为了防止多个信道在同一时间争抢同一频点，因此为达该目的，同一跳频系统下，各个载频使用的MAIO必须不同。本实施例中，由于共享频点是按照距离LTE网络中心频点由近到远的顺序共享的，按照上述规则分配频点后，跳频系统中的载频就按照对应的MAIO由 大到小的顺序空出，这样可以保证后续步骤中修改跳频系统后仍能稳定运转。
例如，请参照图4，图4为具有3个载频的跳频系统分配有3个共享频点f1、f2和f3。跳频系统中的3个载频——载频1、载频2、载频3，对应使用的MAIO为0、1、2。3个共享频点的优先级由低至高排序依次为f3、f2、f1，将共享频点f1分配给载频1，将共享频点f2分配给载频2，将共享频点f3分配给载频3。
步骤S3000，当检测到跳频系统中存在空闲载频，在比所述空闲载频中的共享频点优先级低的频点均已共享的情况下，将所述空闲载频中的共享频点共享给LTE网络使用。
在步骤S3000的一些实施例中，当检测到跳频系统中存在空闲载频，且比空闲载频的共享频点优先级低的共享频点均已共享，才将空闲载频中的共享频点共享给LTE网络使用，这样设置的目的是LTE网络能够使用连续的频段。
如图3所示，在步骤S3000的另一些实施例中，当检测到跳频系统中存在空闲载频后，在比所述空闲载频中的共享频点优先级低的频点均已共享、及剩余非空闲载频的业务负荷小于预设的业务负荷门限的情况下，将空闲载频中的共享频点共享给LTE网络使用。这样设置，一方面保证LTE网络能够使用的频段是连续的，另一方面，在确保跳频系统足以应对当前业务量的共享条件下，才进行频点共享，以保障GSM网络的服务性能稳定。
步骤S3000在实际操作中，可根据实际应用场景选择不修改跳频系统或者修改跳频系统的方式，实现空闲载频的共享频点共享给LTE网络使用。
如图5所示，对于不修改跳频系统的实施方式，可通过以下步骤实现：
步骤S3110，等待跳频系统中所有载频上的业务全部释放；
步骤S3120，将跳频系统中的共享频点全部释放给LTE网络使用。
该种方式实现简单，跳频频点可共享，对现有系统改动小，但是共享速度慢，跳频频谱共享收益低。
如图6所示，对于修改跳频系统的实施方式，可通过以下步骤实现：
步骤S3210，修改跳频系统中的载频的跳频属性；
步骤S3220，将当前空闲载频的共享频点释放给LTE网络使用。
如图7所示，在一实施例中，步骤S3210包括如下子步骤：
步骤S3211，设置p的初始值为0；
循环执行以下步骤直至满足退出条件p>7；
步骤S3212，闭塞非空闲载频的时隙p；
步骤S3213，转移或者释放非空闲载频的时隙p上的业务；
步骤S3214，将当前空闲载频的时隙p的跳频属性设置为不跳频；
步骤S3215，将非空闲载频的时隙p的跳频属性设置为使用除当前空闲载频将要释放的共享频点外的其余跳频频点进行跳频；
步骤S3216，解闭塞非空闲载频的时隙p；
步骤S3217，p＝p+1。
以图4所示的跳频系统为例，当检测到载频3当前处于空闲状态，并且符合共享条件，即比频点f3优先级低的频点均已共享，同时该跳频系统支持修改，则可以通过如下步骤修改跳频系统中的载频的跳频属性：先闭塞非空闲的载频1、载频2的时隙0，停止向载频1、载频2的时隙0传送业务数据；转移或者释放非空闲载频的时隙0上的业务；将载频3的时隙0设置为不跳频；将载频1、载频2的时隙0设置为使用除载频3将要释放的共享频 点f3外的其它跳频频点，即使用频点f1、f2；解闭塞载频1、载频2的的时隙0，使载频1、载频2的的时隙0重新被激活；由此实现对跳频系统中的载频1、载频2和载频3的0时隙的跳频属性进行修改，并基于前述步骤依次对载频1、载频2和载频3中的时隙1至时隙7的跳频属性进行修改。
如图8所示，在一些实施例中，步骤S3210还包括：
步骤3218，向基站系统发送跳频属性设置信息；
步骤3219，接收基站系统发送的跳频属性设置生效的应答信息。
在每一次循环过程中，完成跳频系统中各载频对应的时隙p跳频属性修改设置后，基站控制器便会向基站系统发起数据同步，向基站系统连续发送多条跳频属性设置信息，基站系统接收到基站控制器发送的跳频属性设置信息后，对其下对应的载频的时隙设置新的跳频属性，并返回跳频属性设置生效的应答信息给基站控制器；基站控制器接收基站系统发送的跳频属性设置生效的应答信息，然后解闭塞非空闲载频的时隙p。
在另一些实施例中，也可以是在跳频系统中所有载频的所有时隙的跳频属性均完成修改设置后，基站控制器再向基站系统发起数据同步，基站系统一次性地对其下所有载频的所有时隙设置新的跳频属性，并返回跳频属性设置生效的应答信息给基站控制器；基站控制器接收基站系统发送的跳频属性设置生效的应答信息，然后解闭塞各个非空闲载频的时隙。
参照图9，步骤S3213的一实施例中，转移或者释放非空闲载频的时隙p上的业务，包括：
步骤S32131，触发非空闲载频的时隙p上的业务进行转移；
步骤S32132，设置延时定时器，当延时定时器超时后，将非空闲载频中未转移的业务释放。
本实施例中，通过延时定时器限定非空闲载频的时隙p上的业务转移的时间，当延时定时器超时后，仍存在未完成的业务转移，则采取强制释放业务的措施，保证跳频共享能够顺利进行。
在一些实施例中，当修改过程中出现异常或者有跳频属性及共享相关的配置更改，终止修改过程，恢复跳频系统未修改前的属性，用于确保跳频系统的业务功能正常。
在一些实施例中，终止修改过程，恢复跳频系统未修改前的属性之后还包括将当前空闲载频将要释放的共享频点标记为被GSM网络占用，等待后续重新发起共享。
在一些实施例中，当修改跳频系统中的载频的跳频属性过程中存在大量业务接入，终止修改过程，确保跳频系统的业务功能正常。
第二方面，本申请实施例提供了一种跳频频点的回收方法，在跳频系统已通过前述的共享方法将共享频点共享给LTE网络的情况下，根据业务占用的情况，回收共享频点并将回收的共享频点重新加入到跳频系统中。
参照图10，在一实施例中，针对不修改跳频系统的情况，通过以下步骤将共享给LTE网络的共享频点回收至跳频系统：
步骤S5000，通知LTE网络需要回收全部的共享频点；
步骤S5100，回收全部共享频点至跳频系统中；
步骤S5200，将回收的共享频点重新分配给跳频系统的载频使用。
当属于某个跳频系统的所有共享频点都被共享之后，如果GSM侧有业务占用信道时， 判断负荷升高，需要占用跳频系统中的一个载频时，如果不支持修改跳频系统，则会将该跳频系统中的所有共享频点全部收回。向LTE发送消息，回收跳频系统中的所有共享频点。
参照图11，在另一实施例中，针对需修改跳频系统的情况，通过以下步骤将共享给LTE网络的共享频点回收至跳频系统：
步骤S5300，通知LTE网络需要回收的共享频点。
步骤S5400，回收部分或者全部共享频点至跳频系统中；
步骤S5500，修改跳频系统中的载频的跳频属性，将回收的共享频点重新分配给跳频系统的载频使用。
其中，参照图12，步骤S5500可以包括以下步骤：
步骤S5510，设置p的初始值为0；
循环执行以下步骤直至满足退出条件p>7；
步骤S5520，闭塞各个载频的时隙p；
步骤S5530，转移或者释放各个载频的时隙p上的业务；
步骤S5540，为跳频系统中的各个载频的时隙p加入回收的共享频点；
步骤S5550，解闭塞各个载频的时隙p；
步骤S5560，设置p＝p+1。
参照图13，在一实施例中，解闭各个载频的时隙p之前还包括：
步骤S5570，向基站系统发送跳频属性设置信息；
步骤S5580，接收基站系统发送的跳频属性设置生效的应答信息。
本实施例，在每一次循环过程中，完成跳频系统中各载频对应的时隙p跳频属性修改设置后，基站控制器便会向基站系统发起数据同步，向基站系统连续发送多条跳频属性设置信息，基站系统接收到基站控制器发送的跳频属性设置信息后，对其下对应的载频的时隙设置新的跳频属性，修改相应时隙的频率参数，并返回跳频属性设置生效的应答信息给基站控制器；基站控制器接收基站系统发送的跳频属性设置生效的应答信息，然后解闭塞非空闲载频的时隙p。
在另一些实施例中，也可以是在跳频系统中所有载频的所有时隙的跳频属性均完成修改设置后，基站控制器再向基站系统发起数据同步，基站系统一次性地对其下所有载频的所有时隙设置新的跳频属性，并返回跳频属性设置生效的应答信息给基站控制器；基站控制器接收基站系统发送的跳频属性设置生效的应答信息，解闭塞各个非空闲载频的时隙。
参照图14，步骤5530可通过以下步骤实现：
步骤S5531，触发各载频的时隙p上的业务进行转移；
步骤S5532，设置延时定时器，延时定时器超时后，在存在载频未完成业务转移的情况下，将跳频系统中未转移的业务释放。
在一些实施例中，转移或者释放各个载频的时隙p上的业务，若延时定时器超时前，业务已经释放，则终止对跳频系统中各个载频的时隙p的跳频属性进行修改，将共享频点重新共享给LTE使用。
