Due to historical reasons, operators often operate networks of multiple standards at the same time. After 5G is deployed, there will be scenarios where 2G, 3G, 4G, and 5G operate simultaneously. As the demand for mobile broadband network service traffic continues to increase, it is the general trend for operators to re-cultivation of 2G/3G networks to 4G and from 4G to 5G. In the traditional operator's multi-standard network, each system needs to occupy a certain amount of spectrum resources. Since each system exclusively occupies the spectrum, the spectrum between different systems cannot be used for peak shifting, resulting in a serious waste of spectrum resources.

背景技术
频谱资源是运营商最重要的资产之一，不断提升频谱利用率是运营商一贯的诉求。由于历史原因，运营商往往同时运营多个制式的网络，5G部署后，会存在2G、3G、4G、5G同时运营的场景。随着移动宽带网络业务流量需求的不断增加，运营商2G/3G网络重耕到4G，从4G重耕到5G，已是大势所趋。传统运营商多制式网络中每个制式都需要固定占用一定的频谱资源，由于每个制式都独占频谱，不同制式间的频谱不能错峰共享使用，导致了频谱资源的严重浪费。频谱共享技术能够实现在同一频段按需、动态地调度频谱资源，成为运营商的必然选择。
以4G/5G动态频谱共享为例，4G为宽带系统，信道配置相对粗放，控制信道、导频等均为全频带映射，而5G也为宽带系统，同样存在各类物理信道，如何既能完美解决两种制式之间的各种物理信道的干扰，又能提升业务信道在共享频谱上整体频谱利用率，需要有统筹合理的算法支撑。
如图1a所示，目前某运营商在2.6GHz频段上已经部署3x20MHz TDD-LTE(Time Division Long Term，长期演进)，如果开通100MHz带宽5G NR(5G New Radio)，将与现网4G TDD-LTE频谱冲突，需要现网4G释放出2x20MHz带宽(2575-2615MHz)，即两个频点需要清频，否则现阶段只能开通60M带宽5G，峰值速率无法与其他运营商竞争。如果大面积开通两个频点替代清频的频点，还存在有些终端不支持开通频点,出现重配失败的RRC(Radio Resource Control,无线资源控制)重建立现象，一段时间内还存在NR100M与所述清频的频点共存现象，为了充分使用频谱资源，降低NR100M与LTE频点之间相互干扰，产生4G/5G频谱共享方案。
如图1b所示，传统的动态频谱共享方案是基于4G LTE系统的PRB(Physical Resource  Block，物理资源块)利用率，把4G LTE的部分频段共享给5G系统。但是当5G用户的调度占用到共享频谱时，用户调度的MCS(Modulation and Coding Scheme，调制与编码策略)上不去，峰值速率无法得到有效的保障，用户感知并没有显著提升。

发明人发现，传统的动态频谱共享方案目前只是实现频谱共享的功能，即单纯的把4G共享频段加入到现有5G频段的带宽中，频谱共享模式开启后，5G小区的调度算法没有考虑周围4G小区的干扰，而影响5G用户感知度。因此，本公开实施例提出了一种频谱共享模式下频谱资源调度方法，针对共享频段进行单独的评估，从而整体提升用户感知度。
本公开实施例提供一种频谱资源调度方法，所述方法用于调度共存的至少两个网络制式的频谱资源，所述两个网络制式包括第一网络制式和第二网络制式。在本公开实施例中，当共享频谱生效后，第一网络制式的共享频段作为第二网络制式的单独配置BWP(Band Width Part,带宽部分)，记为BWP share。第二网络制式原始配置的BWP(即原始频段)记为BWP old，这样，在共享频谱以后，第二网络制式的带宽变为(BWP share+BWP old)。
如图2所示，本公开实施例提供的频谱资源调度方法包括以下步骤：
步骤11，确定第一网络制式的共享频段的信道质量参数。
在本步骤中，确定预设的评估周期T share内第一网络制式的共享频段的信道质量参数。
步骤12，若信道质量参数满足预设的第一条件，则在第一网络制式的共享频段内调度频谱资源，或者，在第一网络制式的共享频段和第二网络制式的原始频段内调度频谱资源。
评估共享频段信道质量是否满足第一条件的步骤，后续再详细说明。
本公开实施例提供的频谱资源调度方法，用于调度共存的至少两个网络制式的频谱资源，所述两个网络制式包括第一网络制式和第二网络制式，所述方法包括：确定第一网络制式的共享频段的信道质量参数，若信道质量参数满足预设的第一条件，则在第一网络制式的共享频段内调度频谱资源，或者，在第一网络制式的共享频段和第二网络制式的原始频段内调度频谱资源，这样，通过评估共享频段的信道质量，充分考虑共享频段对用户的干扰，只有在共享频段的信道质量满足一定条件的情况下才可以调用共享信道的频谱资源，从而优化调度使用共享频段，提升用户感知度。
本公开实施例中，信道质量参数是用于反映信道质量好坏的参数，在一些实施例中，信道质量参数包括但不限于频谱效率和/或评估周期(即T share)内的平均信道质量指示，需要说明的是，频谱效率为T share内的频谱效率。
当信道质量参数为频谱效率时，则所述信道质量参数满足预设的第一条件包括：频谱效率大于预设的第一阈值。当信道质量参数包括预设的评估周期内的平均信道质量指示时，所述信道质量参数满足预设的第一条件包括：预设的评估周期内的平均信道质量指示大于预设的第二阈值。当信道质量参数包括频谱效率和预设的评估周期内的平均信道质量指示时，所述信道质量参数满足预设的第一条件包括：频谱效率大于预设的第一阈值且预设的评估周期内的平均信道质量指示大于预设的第二阈值。
在一些实施例中，若信道质量参数满足预设的第一条件，则调度频谱资源的步骤，即在第一网络制式的共享频段内调度频谱资源，或者，在第一网络制式的共享频段和第二网络制式的原始频段内调度频谱资源，包括：优先在第一网络制式的共享频段内调度频谱资源。
在一些实施例中，所述优先在第一网络制式的共享频段内调度频谱资源，包括：若第一网络制式的共享频段内的频谱资源满足用户需求，则在第一网络制式的共享频段内调度频谱资源；若第一网络制式的共享频段的频谱资源不满足用户需求，则在第一网络制式的共享频段内调度频谱资源之后，在第二网络制式的原始频段内调度频谱 资源。也就是说，先调度第一网络制式的共享频段内的频谱资源，在共享频段内的频谱资源不足时再调用第二网络制式的原始频段内的频谱资源。
本公开实施例在第一网络制式的共享频段的信道质量评估通过后(即共享频段的信道质量较好的情况)，进一步判断该共享频段内的频谱资源能否满足用户需求，优先使用该共享频段内的频谱资源，可以节省第二网络制式的原始频段的频谱资源。
在一些实施例中，根据预设的调度周期(T max)确定所述第一网络制式的共享频段的信道质量参数。也就是说，按照调度周期调度共享信道内的频谱资源，从而可以灵活调整频谱资源调度，提高实时性。
在一些实施例中，本公开实施例的频谱资源调度方法还可以包括以下步骤：若信道质量参数不满足第一条件，则在第二网络制式的原始频段内调度频谱资源。也就是说，在第一网络制式的共享频段的信道质量较差时，不调度该共享频段的频谱资源，而是调度第二网络制式的原始频段内的频谱资源，从而保证用户业务的稳定性，提升用户感知度。
在一些实施例中，为了进一步合理调度频谱资源，如图3所示，在对第一网络制式的共享频段的信道质量进行评估之前，即在确定所述第一网络制式的共享频段的信道质量参数(步骤11)之前，本公开实施例的频谱资源调度方法还可以包括以下步骤：
步骤10，确定用户等级、用户业务类型和第二网络制式的原始频段的物理资源块利用率。
在本步骤中，当用户终端接入网络后，确定用户等级、用户业务类型和第二网络制式的原始频段的物理资源块利用率。
在本公开实施例中，用户等级是指用户重要性的等级，例如，VIP用户，用户等级可以从运营商设备获取，通常，通信资费花费越高的用户，其用户等级越高。
用户业务类型可以通过获取QoS(Quality of Service，服务质量)参数确定，具体的，可以通过QoS中的时延、时延变化(包括抖动和漂移)和丢包率等指标确定用户业务类型。在本公开实施例中，预设类型的用户业务是指低时延且高可靠性的用户业务，例如，语音通话业务等。
相应的，所述确定第一网络制式的共享频段的信道质量参数(即步骤11)，包括以下步骤：
步骤11’，若用户等级、用户业务类型和第二网络制式的原始频段的物理资源块利用率满足预设的第二条件，则确定第一网络制式的共享频段的信道质量参数。
在本步骤中，若用户等级、用户业务类型和第二网络制式的原始频段的物理资源 块利用率满足预设的第二条件，说明初步判断出可以调度第一网络制式的共享频段的频谱资源，至于最终是否能够真正调度第一网络制式的共享频段的频谱资源，还需进一步评估该共享频段的信道质量(即执行步骤11)。
在本公开实施例中，在调用频谱资源时，综合考虑了用户等级、用户业务类型和第二网络制式的原始频段的物理资源块利用率，使得频谱资源调用更为合理，提高用户业务的稳定性，保证用户体验和感知度。
在一些实施例中，所述用户等级、用户业务类型和第二网络制式的原始频段的物理资源块利用率满足预设的第二条件，包括：用户等级小于预设等级，且第二网络制式的原始频段的物理资源块利用率大于预设的第四阈值，且用户业务类型为非预设类型。其中，第四阈值为共享模式下原始频段带宽的负荷门限。也就是说，针对用户等级较低的用户使用非预设类型的用户业务，而当前第二网络制式的原始频段的物理资源块利用率较大的情况，由于用户以及业务本身对频谱资源要求并不是太高，可以为该用户调度第一网络制式的共享频段内的频谱资源。
在一些实施例中，本公开实施例的频谱资源调度方法还包括以下步骤：若用户等级、用户业务类型和第二网络制式的原始频段的物理资源块利用率不满足第二条件，则在第二网络制式的原始频段内调度频谱资源。在本步骤中，若用户等级、用户业务类型和第二网络制式的原始频段的物理资源块利用率不满足第二条件，则确定不能调度第一网络制式的共享频段的频谱资源，否则会影响用户业务可靠性以及用户体验，因此，在这种情况下，在第二网络制式的原始频段内调度频谱资源，以保证业务可靠性以及用户体验。
在一些实施例中，所述用户等级、用户业务类型和第二网络制式的原始频段的物理资源块利用率不满足第二条件，包括以下(1)-(3)之一：
(1)用户等级大于或等于预设等级；
(2)用户等级小于预设等级且所述第二网络制式的原始频段的物理资源块利用率小于或等于预设的第四阈值；
(3)用户等级小于预设等级且所述第二网络制式的原始频段的物理资源块利用率大于预设的第四阈值且用户业务类型为预设类型。
也就是说，针对较高等级的用户，为其调度第二网络制式的原始频段内的频谱资源，以保证业务可靠性以及用户体验。在第二网络制式的原始频段的物理资源块利用率较低的情况下，针对较低等级的用户，也可以为其调度第二网络制式的原始频段内的频谱资源。在第二网络制式的原始频段的物理资源块利用率较高的情况下，虽然用户等级较低，但其当前正在使用低时延、高可靠性业务，也可以为其调度第二网络制 式的原始频段内的频谱资源，以保证业务可靠性。
在一些实施例中，在完成一次调度之后，还可以进一步判断是否还需再次调度频谱资源，以保证用户业务完成。也就是说，在第二网络制式的原始频段内调度频谱资源之后，或者，在第一网络制式的共享频段内调度频谱资源之后，或者，在第一网络制式的共享频段和第二网络制式的原始频段内调度频谱资源之后，所述频谱资源调度方法还包括以下步骤：
判断是否还需要调度频谱资源，若需要，则针对用户等级小于预设等级的用户，确定第二网络制式的原始频段当前的物理资源块利用率，以根据用户等级、用户业务类型和第二网络制式的原始频段当前的物理资源块利用率是否满足第二条件的判断结果调度频谱资源(即执行步骤11’)，或者，针对用户等级大于或等于预设等级的用户，在第二网络制式的原始频段内调度频谱资源。需要说明的是，由于用户等级和用户业务类型在短期内不会发生改变，而第二网络制式的原始频段当前的物理资源块利用率则是实时发生变化的，因此，在判断出还需要调度频谱资源时，针对用户等级小于预设等级的用户，可以只重新确定第二网络制式的原始频段当前的物理资源块利用率即可。
为了清楚说明本公开实施例的方案，以下结合具体实施例对本公开的上述方法的示例性实现方式进行详细说明。
在本公开实施例中以调度两个网络制式的频谱资源为例，其中第一网络制式为4G，第二网络制式为5G，5G小区获得4G LTE小区的共享频段，在共享频段上设定一个BWP，记为BWP share，5G小区的原始频段上设定一个或多个BWP，记为BWP old。共享频段的信道质量参数为频谱效率E share。
如图4所示，本公开实施例的频谱资源调度方法包括以下步骤：
步骤401，确定用户等级、用户业务类型和5G小区原始频段的PRB利用率P PRBold。
步骤402，判断用户等级是否大于预设等级，若是，则执行步骤408，否则，执行步骤403。
在本步骤中，若判断出用户为较高等级用户(例如VIP用户)，则直接在BWP old内调度频谱资源(即执行步骤408)；若判断出用户为较低等级用户，则还需结合P PRBold和用户业务类型做进一步判断(即执行步骤403)。
步骤403，判断P PRBold是否大于P expection(即第四阈值)，若是，则执行步骤404，否则，执行步骤408。
在本步骤中，若判断出P PRBold>P expection，则还需进一步判断用户业务类型(即执行步骤404)；若判断出P PRBold≤P expection，则在BWP old内调度频谱资源(即执行步骤408)。
步骤404，判断用户业务类型是否属于预设类型，若不属于，则执行步骤405；若属于，则执行步骤408。
在本步骤中，若判断出用户业务类型不属于低时延且高可靠性的业务类型，则需要进一步评估共享信道的信道质量(即执行步骤405)；若判断出用户业务类型属于低时延且高可靠性的业务类型(即预设类型)，则在BWP old内调度频谱资源(即执行步骤408)。
步骤405，确定评估周期T share内共享时段的频谱效率E share。
步骤406，判断E share是否大于第一阈值E expection，若大于，则执行步骤407，否则，执行步骤408。
在本步骤中，若判断出E share>E expection，说明满足第一条件，则可以在BWP share内调度频谱资源(即执行步骤407)；若判断出E share≤E expection，说明不满足第一条件，则在BWP old内调度频谱资源(即执行步骤408)。
步骤407，在BWP share内调度频谱资源，或者，在(BWP share+BWP old)内调度频谱资源。
在本步骤中，在(T max-T share)时间段内调度频谱资源。
步骤408，在BWP old内调度频谱资源。
需要说明的是，在步骤407、408之后，还包括以下步骤：判断是否还需要调度频谱资源，若不需要，则结束流程；若需要，则针对较低等级的用户，确定P PRBold，并判断P PRBold是否大于P expection(即执行步骤403)，以及，针对较高等级的用户，直接在BWP old内调度频谱资源(即执行步骤408)。
本公开实施例提供的频谱资源调度方法，能够克服一些情况中存在的没有针对共享频段进行评估，仅仅单纯将4G共享频段加入到5G原始频段的带宽中，从而影响5G用户感知度的问题，达到了优化调度使用4G共享频段，提升用户感知度的效果。

    用户等级大于或等于预设等级；
    用户等级小于预设等级且所述第二网络制式的原始频段的物理资源块利用率小于或等于预设的第四阈值；
    用户等级小于预设等级且所述第二网络制式的原始频段的物理资源块利用率大于预设的第四阈值且用户业务类型为预设类型。
  12. 如权利要求10所述的方法，其中，在所述的第二网络制式的原始频段内调度频谱资源的步骤之后，或者，在所述的第一网络制式的共享频段内调度频谱资源的步骤之后，或者，在所述的第一网络制式的共享频段和所述第二网络制式的原始频段内调度频谱资源的步骤之后，还包括：
    判断是否还需要调度频谱资源，若需要，则针对用户等级小于预设等级的用户，确定所述第二网络制式的原始频段当前的物理资源块利用率，以根据所述用户等级、所述用户业务类型和所述第二网络制式的原始频段当前的物理资源块利用率是否满足所述第二条件的判断结果调度频谱资源，或者，针对用户等级大于或等于预设等级的用户，在所述第二网络制式的原始频段内调度频谱资源。
  13. 一种频谱资源调度装置，包括第一确定模块和调度模块，其中，
    所述第一确定模块被设置成，确定所述第一网络制式的共享频段的信道质量参数；
    所述调度模块被设置成，当所述信道质量参数满足预设的第一条件时，在所述第一网络制式的共享频段内调度频谱资源，或者，在所述第一网络制式的共享频段和所述第二网络制式的原始频段内调度频谱资源。
  14. 一种计算机设备，包括：
    一个或多个处理器；
    存储装置，其上存储有一个或多个程序；其中，
    当所述一个或多个程序被所述一个或多个处理器执行时，使得所述一个或多个处理器实现如权利要求1-12任一项所述的频谱资源调度方法。
  15. 一种计算机可读介质，其上存储有计算机程序，其中，所述程序被执行时实现如权利要求1-12任一项所述的频谱资源调度方法。
