Description

服务质量分类标识QCI业务的调度方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种服务质量分类标识(Quality of Service Class Identifier，简称为QCI)业务的调度方法及装置。
背景技术
在当前第三代移动通讯伙伴计划(3rd Generation partnership project，简称为3GPP)协议中，通常将业务按照不同的属性划分为不同的种类，即每类业务用QCI表示。3GPP协议规定了QCI种类有256种，但目前协议仅定义了9类QCI业务，每类QCI中也给出了至少一种业务范例，除了给出至少一种业务范例外，还规定了该类业务的资源类型，优先级、包延迟预算，丢包率的属性。
按照协议规定的QCI范围(即256种QCI)，未来支持运营商配置剩余的247(256-9)种QCI，对于这些剩余的247种QCI，相关QCI协议并没有定义业务的上述属性，甚至没有规定如何定义，目前的调度算法为了保证业务的质量要求，满足业务的服务质量(Quality of Service，简称为QoS)属性，需要参考业务的上述属性进行调度策略的选择，如果未来扩展QCI业务仅给出QCI标识，并不定义该QCI上述属性，则无法和目前的调度算法兼容，即现有的调度策略主要针对已经定义的QCI业务种类，没有考虑剩余的247种QCI业务，不能适应未来通信系统中扩展QCI的调度需求。
针对相关技术中，对于协议里规定的256中QCI仅定义了9种而导致的QCI业务扩展性差，不能适应未来业务扩展性差的问题，尚未提出有效的解决方案。
发明内容
为了解决上述技术问题，本发明提供了一种QCI业务的调度方法及装置。
根据本发明的一个实施例，提供了一种服务质量分类标识QCI业务的调度方法，包括：获取接入当前小区内业务的QCI；在所述QCI指示所述业务为扩展QCI业务时，根据所述业务的业务属性参数对所述扩展QCI业务的QCI属性参数进行配置，其中，所述扩展QCI业务为QCI索引大于9小于255的QCI业务；根据配置后的QCI属性参数对所述业务进行调度。
优选地，所述业务属性参数包括以下至少之一：QCI、保证比特速率(Guaranteed Bit Rate,简称GBR)、最大比特速率(Maximum Bit Rate,简称MBR)、聚合最大比特速率(Aggregate Maximum Bit Rate，简称AMBR)、分配保留优先级(Allocation Retention Priority，简称为ARP)；和/或所述QCI属性参数包括以下至少之一：所述业务的资源类型、所述业务的优先级、所述业务的包时延、所述业务的丢包率。
优选地，通过以下方式配置所述业务的资源类型：判断所述业务属性参数中是否包含所述GBR；如果是，则配置所述业务的资源类型为GBR业务；如果否，则配置所述业务的资源类型为NonGBR业务。
优选地，通过以下方式配置所述业务的优先级：对于资源类型为GBR业务的业务，根据所述GBR的取值配置所述业务的优先级；对于资源类型为NonGBR业务的业务，根据所述ARP配置所述业务的优先级。
优选地，所述GBR业务的优先级高于所述NonGBR业务的优先级。
优选地，通过以下方式配置所述业务的包时延和/或丢包率：当网络侧下发的信息中包括所述业务的业务类型时，将所述业务类型在第三代移动通讯伙伴计划3GPP协议中的包时延和/或丢包率对应配置为所述业务的包时延和/或丢包率；当网络侧下发的信息中不包括所述业务的业务类型时，根据与所述业务的GBR值或ARP值对所述业务的包时延和/或丢包率进行配置。
优选地，根据与所述业务的GBR值或ARP值对所述业务的包时延和/或丢包率进行配置，包括：对于资源类型为GBR业务的业务，确定与所述业务的GBR值差值最小的非扩展QCI业务，并将所述非扩展QCI业务的包时延和/或丢包率对应配置为所述业务的包时延和/或丢包率，其中，所述非扩展QCI为索引小于或者等于9的QCI；对于资源类型为NonGBR业务的业务，确定与所述业务的ARP值差值最小的非扩展QCI，并将所述非扩展QCI下的包时延和/或丢包率对应配置为所述业务的包时延和/或丢包率。
根据本发明的另一个实施例，还提供了一种服务质量分类标识QCI业务的调度装置，包括：获取模块，设置为获取接入当前小区内业务的QCI；配置模块，设置为在所述QCI指示所述业务为扩展QCI业务时，根据所述业务的业务属性参数对所述扩展QCI业务的QCI属性参数进行配置，其中，所述扩展QCI业务为QCI索引大于9小于255的QCI业务；调度模块，设置为根据配置后的QCI属性参数对所述业务进行调度。
优选地，所述配置模块设置为在所述业务属性参数包括以下至少之一：QCI、保证比特速率GBR、最大比特速率MBR、聚合最大比特速率AMBR、ARP；和/或所述QCI属性参数包括以下至少之一：所述业务的资源类型、所述业务的优先级、所述业务的包时延、所述业务的丢包率时，根据所述业务的业务属性参数对所述扩展QCI业务的QCI属性参数进行配置。

附图说明
此处所说明的附图用来提供对本发明的进一步理解，构成本申请的一部分，本发明的示意性实施例及其说明用于解释本发明，并不构成对本发明的不当限定。在附图中：
图1是根据本发明实施例的QCI业务的调度方法的流程图；
图2是根据本发明实施例的QCI业务的参数配置流程图；
图3为根据本发明优选实施例的调度器的结构框图；
图4是根据本发明实施例的QCI业务的调度装置的结构框图；

图6是根据本发明优选实施的QCI业务的参数配置流程图。
具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
本发明实施例的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本发明而了解。本发明实施例的目的和其他优点可通过在所写的说明书、权利要求书、以及附图中所特别指出的结构来实现和获得。
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
相关技术中定义的9种QCI除了给出至少一种业务范例外，还规定了该类业务的资源类型，优先级、包延迟预算，丢包率的属性，以下简单对上述参数进行解释说明：
业务的资源类型是指该种业务在网络中是用保证比特速率(Guaranteed Bit Rate，简称为GBR，其由核心网配置)传输还是用非保证比特速率(NonGBR)传输，如果是保证比特速率传输，那么基站就必须优先保证，也就是带宽资源优先用于GBR业务的传输；如果是非保证比特速率，那么基站在保证GBR业务后，可以根据不同的调度准则将剩余资源分配给NonGBR业务。
优先级表示QCI之间的相互优先关系，每种QCI都会对应一个优先级，优先级值越小表示优先级越高，eNB对于该类业务应该优先保证。
包时延(Packet Delay Budget，简称为PDB)：表示分组数据包在用户设备(User Equipment，简称为UE)与核心网间的最大时延，为了保证分组数据包的有效性，该值是调度器重要考虑的参数。
丢包率(Packet Error Loss Rate，简称为PER)表示无线链路层除了拥塞原因外的分组数据包丢失率，也就是除了拥塞原因外发送端的无线链路控制(Radio Link Control，简称为RLC)层已经发送但是接收端RLC层没有成功收到数据包所占的比例的上限。
而对于上述参数，相关技术中并没有给出具体的定义方案。
为了解决上述技术问题，在本实施例中提供了一种QCI业务的调度方法，图1是根据本发明实施例的QCI业务的调度方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，获取接入当前小区内业务的QCI；
步骤S104，在上述QCI指示上述业务为扩展QCI业务时，根据上述业务的业务属性参数对上述扩展QCI业务的QCI属性参数进行配置，其中，上述扩展QCI业务为QCI索引大于9小于255的QCI业务；
步骤S106，根据配置后的QCI属性参数对上述业务进行调度。
通过上述各个步骤，采用在确定业务属性参数中所携带的QCI为上述扩展的QCI业务时，根据业务的业务属性参数对QCI业务的相关属性参数进行配置的技术方案，解决了相关技术中对于协议里规定的256中QCI仅定义了9种而导致的QCI业务扩展性差，不能适应未来业务扩展性差的问题，满足了不同用户的不同业务需求，最大化的适应未来通信系统中业务扩展的需求，进一步保证业务的Qos属性。
可选地，上述步骤S104中的业务属性参数包括以下至少之一：QCI、保证比特速率GBR、最大比特速率MBR、聚合最大比特速率AMBR、ARP；和/或QCI属性参数包括以下至少之一：业务的资源类型、业务的优先级、业务的包时延、业务的丢包率。
在具体实施例过程中，步骤S104有多种实现方式，本发明优选实施例提供了以下技术方案分别来配置上述QCI属性参数：业务的资源类型、业务的优先级、业务的包时延、业务的丢包率，如图2所示：
步骤S202：通过以下方式配置上述业务的资源类型：判断上述业务属性参数中是否包含上述GBR；如果是，则配置上述业务的资源类型为GBR业务；如果否，则配置上述业务的资源类型为NonGBR业务。
步骤S204：通过以下方式配置上述业务的优先级：对于资源类型为GBR业务的业务，根据上述GBR的取值配置上述业务的优先级；对于资源类型为NonGBR业务的业务，根据上述ARP配置上述业务的优先级。
在本发明实施例中，上述GBR业务的优先级高于上述NonGBR业务的优先级。
步骤S206：通过以下方式配置上述业务的包时延和/或丢包率：当获取到上述业务的业务类型时，将上述业务类型在第三代移动通讯伙伴计划3GPP协议中的包时延和/ 或丢包率配置为上述业务的包时延和/或丢包率；当未获取到上述业务的业务类型时，根据与上述业务的资源类型所对应的配置规则对上述业务的包时延和/或丢包率进行配置。
在本发明实施例的一个可选实施例中，根据上述业务的资源类型对上述业务的包时延和/或丢包率进行配置，包括：对于资源类型为GBR业务的业务，确定与上述业务的GBR值差值最小的非扩展QCI业务，并将上述非扩展QCI业务的包时延和/或丢包率配置为上述业务的包时延和/或丢包率，其中，上述非扩展QCI为索引小于或者等于9的QCI；对于资源类型为NonGBR业务的业务，确定与上述业务的ARP值差值最小的非扩展QCI，并将上述非扩展QCI下的包时延和/或丢包率配置为上述业务的包时延和/或丢包率。
为了更好的理解上述QCI属性参数：业务的资源类型、业务的优先级、业务的包时延、业务的丢包率的配置过程，以下结合一个优选示例进行说明：
首先，确定业务资源类型，如果业务属性参数中包含GBR速率，则该业务为GBR业务，否则为NonGBR业务，即采用上述技术方案就能够确定业务的资源类型。
其次，确定业务优先级，对于GBR业务，可以根据GBR速率匹配业务优先级，GBR速率越小的业务，其优先级越高，否则优先级越低，将扩展QCI GBR业务的GBR速率和一般QCI业务的GBR速率比较，在保证小区GBR业务的优先级高于NonGBR业务优先级的前提下，为扩展QCI GBR业务选择一个合适的优先级别；对于NonGBR业务，可以根据业务ARP级别匹配业务优先级，ARP级别越高，其优先级越高，否则优先级越低，将扩展QCI NonGBR业务的ARP和一般QCI NonGBR业务的ARP比较，在保证Ue的扩展QCI NonGBR业务的优先级高于Ue默认承载业务优先级的前提下，为扩展QCI NonGBR业务选择一个合适的优先级别。
最后，确定业务的PDB和PER，需要说明的是，包时延参数并不是调度过程的必要参数，其可以根据调度算法的实际需要进行调整，决定是否匹配扩展QCI业务的PDB和PER，当然，这两个参数和业务类型息息相关，如果核心网在建立扩展QCI业务时，能够提供业务类型的描述，则可以根据业务类型描述和协议现有的QCI业务类型匹配包时延(PDB)和丢包率(PER)参数；如果获取不到业务类型参数，则对于GBR业务，通过GBR速率匹配这两个参数，根据协议已有的QCI属性参数，找到GBR速率最接近的一般QCI GBR业务的QCI索引，将该索引下的PDB和PER作为扩展QCIGBR业务的PDB和PER；对于NGBR业务，通过ARP匹配这两个参数，根据协议已 有的QCI属性参数，找到ARP最接近的一般QCI NonGBR业务的QCI索引，将该索引下的PDB和PER作为扩展QCI NonGBR业务的PDB和PER。
为了更好的理解上述核心网提供业务类型的描述的情况下，确定QCI属性参数的工作流程以及核心网不提供业务类型的描述的情况下，确定QCI属性参数的工程流程，以下结合几个优选实施例进行说明：

步骤605：根据业务属性参数，业务QCI属性参数，业务配置参数和业务统计参数，根据调度算法，对业务排序和资源分配。
优选实施例五
QCI属性参数中不存在相同的ARP时，确定QCI属性参数的工作流程如下：
步骤701：UE Index＝10的UE初始接入时，建立QCI＝20，ARP＝3，AMBR＝5Mbps的业务，调度器保存该业务的业务属性信息。
步骤703：根据QCI标识，识别扩展QCI业务：QCI＝20，大于9小于255，所以属于扩展QCI业务。
步骤705：根据业务属性参数匹配业务QCI属性参数。

步骤705-3：根据业务属性参数匹配QCI属性参数中的包时延：由于核心网未提供该业务的业务类型，则根据业务的ARP进行匹配：该业务的ARP＝3，当前小区中存在的最接近ARP＝3的NonGBR业务是QCI＝8，ARP＝4的业务，则根据协议匹配QCI＝8业务的包时延为300ms。
步骤705-4：根据业务属性参数匹配QCI属性参数中的丢包率：由于核心网未提供该业务的业务类型，则根据业务的ARP进行匹配：该业务的ARP＝3，当前小区中存在的最接近ARP＝3的NonGBR业务是QCI＝8，ARP＝4的业务，则根据协议匹配QCI＝8业务的丢包率为10-6。

步骤709：根据业务属性参数，业务QCI属性参数，业务配置参数和业务统计参数，根据调度算法，对业务排序和资源分配。
业务配置参数根据业务属性参数和QCI属性参数配置，例如：可以根据ARP，AMBR(对于GBR业务不考虑该属性)，VIP属性(运营商可根据用户的套餐需求配 置，例如：金银铜，金属性最高，铜属性最低)等参数配置业务配置参数，最终影响调度算法中的业务的排序和资源分配，不同的调度算法要求的业务配置参数可能不同也可以相同；业务统计参数，包括用户的信道质量，业务历史吞吐率统计，业务的历史时延统计等，用于不同调度算法进行业务排序和资源分配。
在上述实施例中，根据调度算法对业务排序和资源分配，之所以在调度中考虑业务属性参数，QCI属性参数和业务配置参数，是为了更好地保证多业务时调度的公平性和时效性，从而能够更好地适应未来移动通信系统混合业务的调度需求。
综上所述，本发明实施例提供了一种在移动通信网络中，基于扩展QCI(即上述实施例中提到的247种QCI)的调度方法和装置，主要在通信系统中支持扩展QCI配置时，基站(eNB)能够兼容扩展QCI业务的调度，通过增加调度算法的QCI识别功能，通过已知的扩展QCI业务属性，当未配置QCI属性参数时，自适应匹配业务的QCI属性参数，进而获取业务配置参数，再结合业务统计参数，能够自适应分类排序小区内的接入业务，体现业务属性的特点，保证调度的有序性和时效性。
在本实施例中还提供了一种QCI业务的调度装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图4是根据本发明实施例的QCI业务的调度装置的结构框图，如图4所示，该装置包括：
获取模块40，设置为获取接入当前小区内业务的QCI；
配置模块42，与获取模块40连接，设置为在上述QCI指示上述业务为扩展QCI业务时，根据上述业务的业务属性参数对上述扩展QCI业务的QCI属性参数进行配置，其中，上述扩展QCI业务为QCI索引大于9小于255的QCI业务；
调度模块44，与配置模块42连接，设置为根据配置后的QCI属性参数对上述业务进行调度。
通过上述各个模块的综合作用，采用在确定业务属性参数中所携带的QCI为上述扩展的QCI业务时，根据业务的业务属性参数对QCI业务的相关属性参数进行配置的技术方案，解决了相关技术中对于协议里规定的256中QCI仅定义了9种而导致的 QCI业务扩展性差，不能适应未来业务扩展性差的问题，满足了不同用户的不同业务需求，最大化的适应未来通信系统中业务扩展的需求，进一步保证业务的Qos属性。
在本发明实施例的一个优选实施例中，上述业务属性参数包括以下至少之一：QCI、保证比特速率GBR、最大比特速率MBR、聚合最大比特速率AMBR、ARP；和/或上述QCI属性参数包括以下至少之一：上述业务的资源类型、上述业务的优先级、上述业务的包时延、上述业务的丢包率。
本发明实施例对上述技术方案的进一步改进在于，如图5所示，配置模块42，包括：判断单元420，设置为判断上述业务属性参数中是否包含上述GBR；第一配置单元422，与判断单元420连接，设置为在上述业务属性参数中包含上述GBR时，配置上述业务的资源类型为GBR业务；第二配置单元424，与第一配置单元422连接，设置为在上述业务属性参数中不包含上述GBR时，配置上述业务的资源类型为NonGBR业务，需要说明的是，本发明实施例上述提供的第一配置单元422和第二配置单元424同样可以完成上述业务的优先级、包时延以及丢包率的配置过程。
综上所述，本发明实施例提供的是一种在移动通信网络中，基于扩展QCI的调度方法和装置，主要在通信系统中支持扩展QCI配置时，基站能够兼容扩展QCI业务的调度，通过增加调度算法的QCI识别功能，通过已知的扩展QCI业务属性，当未配置QCI属性参数时，自适应匹配业务的QCI属性参数，进而获取业务配置参数，再结合业务统计参数，自适应分类排序小区内的接入业务，体现业务属性的特点，保证调度的有序性和时效性。
上述技术方案可以总体概括为以下过程，如图6所示：
步骤S602：在一个小区调度开始时，首先获取小区内所有接入业务的业务属性参数；
步骤S604：根据业务的QCI标识，区分业务类型，识别扩展QCI业务，如果否，则转到步骤S606，如果是，则转到步骤S608；
步骤S606：根据QCI索引获取QCI属性参数；
步骤S608：对于扩展QCI业务，根据业务属性参数自适应匹配业务的QCI属性参数；
步骤S610：所有业务根据业务属性参数和QCI属性参数确定业务配置参数；
步骤S612：获取业务统计参数；
步骤S614：最后根据调度算法，对业务进行排序和分配资源。
采用本发明实施例提供的上述技术方案，避免调度算法由于不支持扩展QCI业务导致的业务性能不能保证，同时降低扩展QCI业务对一般QCI业务调度性能的影响，通过综合考虑一般QCI业务和扩展QCI业务的属性，保证调度按照业务属性要求有序进行，提高调度的时效性，同时兼顾调度的公平性，另外兼容扩展QCI业务后，能够更好地满足业务属性的要求以及适应未来移动通信系统混合业务的调度需求。
本发明通过基站和核心网的交互，获取小区内所有接入业务的业务属性参数，根据QCI标识识别出扩展QCI业务，对于扩展QCI业务，根据业务属性参数自适应匹配业务的QCI属性参数；对于一般QCI业务，其QCI属性参数是协议定义的，获取业务的业务属性参数后，根据QCI索引获取QCI属性参数，然后所有业务根据业务属性参数和QCI属性参数确定业务配置参数，并获取业务统计参数，最后依据调度算法，进行排序和资源分配。
另外，在本发明各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
