所述客户端通过所述权限管理配置接口发送包含所述权限管理配置信息的请求。
具体而言,客户端通过冲突策略下发接口发送包含冲突策略的请求;北向接口请求处理功能单元接收该请求,向北向接口请求冲突协调功能单元发送该请求,触发北向接口请求冲突协调功能单元更新冲突策略。
客户端通过权限管理配置接口发送包含权限管理配置信息的请求;北向接口请求处理功能单元接收该请求;向权限管理功能单元发送权限管理配置信息,触发权限管理功能单元更新权限管理配置信息。
可选的,所述能力开放层包括:所述北向接口请求冲突协调功能单元和所述权限管理功能单元;
所述北向接口请求处理功能单元,用于接收所述客户端通过所述功能接口发送的请求,将所述请求发送至所述权限管理功能单元;
所述权限管理功能单元,用于根据所述客户端的身份,判断所述客户端是否有被调用的功能接口的调用权限;若所述客户端有所述调用权限,将所述请求发送至所述北向接口请求冲突协调功能单元;
所述北向接口请求冲突协调功能单元,用于根据所述被调用的功能接口,对所述请求进行冲突验证;针对验证通过的所述请求,触发所述功能层中与所述被调用的功能接口对应的功能模块运行。
具体而言,功能接口对应的中心单元功能层中的功能模块被调用前,还包括以下过程:
(1)身份认证
北向接口请求处理功能单元接收到客户端通过功能接口发送的请求后, 首先将该请求发送至权限管理功能单元,权限管理功能单元对客户端的身份进行认证。
(2)权限确认
权限管理功能单元根据客户端的身份,判断客户端是否有被调用的功能接口的调用权限。例如:根据权限管理配置信息,判断客户端是否有被调用的功能接口的调用权限。
(3)冲突验证
若客户端有调用权限,权限管理单元对该请求进行冲突验证,验证通过,才触发功能层中的功能模块运行。
在本公开的一些可选实施例中,所述权限管理配置信息包括:权限管理列表,所述权限管理列表包括:所述至少一个功能接口中的每一所述功能接口和具备调用所述功能接口的权限的客户端的身份。
可选的,所述权限管理功能单元,用于根据所述客户端的身份和所述权限管理列表,判断所述客户端是否有被调用的功能接口的调用权限。
举例来说,共有2个客户端:客户端M和客户端N,中心单元能力开放层共有3个功能接口:功能接口1、功能接口2和功能接口3。具备调用功能接口1的权限的客户端为客户端M,具备调用功能接口2的权限的客户端为客户端M和客户端N,具备调用功能接口3的权限的客户端为客户端N,即,客户端M具有调用功能接口1和功能接口2的权限,客户端N具有调用功能接口2和功能接口3的权限。
从而,能够支持对调用接口的客户端进行统一认证和相关权限的管理。
由于无线边缘计算及控制需求逐渐兴起,不仅仅是网管层作为CU的能力消费者,无线接入网(Radio Access Network,RAN)边缘控制器和移动边缘计算(Mobile Edge Computing,MEC)都可能成为CU的能力消费者,进行相关数据的采集和控制管理。从而,多消费者的能力调用冲突也是CU能力开放需求解决的问题。
因此,在本公开的一些可选实施例中,所述冲突策略包括:冲突检测接口列表和处理策略。
其中,冲突策略可以包括:冲突策略标识号(ID)、冲突检测接口列表和 处理策略。例如:在冲突策略ID 1下,冲突检测接口列表包括:功能接口1和功能接口2,即,功能接口1和功能接口2会发生冲突,处理策略是拒绝通过功能接口2发送的请求,处理通过功能接口1发送的请求。
以表1为示例,在冲突策略A下,RRM负载均衡算法下发接口和RRM容量优化算法下发接口这2个接口会发生冲突,处理策略是当RRM节能算法启用时,对通过这2个接口发送的请求都拒绝。
Figure PCTCN2020071489-appb-000001
表1
可选的,所述北向接口请求冲突协调功能单元,用于判断所述被调用的功能接口是否在所述冲突检测接口列表中;若所述被调用的接口不在所述冲突检测列表中,或者,所述被调用的接口在所述冲突检测列表中,且所述处理策略为不拒绝通过所述被调用的接口发送的请求,判定所述请求通过冲突验证;若所述被调用的接口在所述冲突检测列表中,且所述处理策略为拒绝通过所述被调用的接口发送的请求,判定所述请求不通过冲突验证。
从而,本公开实施例能够支持外部多方调用,且能够进行统一冲突协调处理,即,能够支持外部调用引发的不同功能模块的冲突协调。
举例来说,在冲突策略ID 2下,冲突检测接口列表包括:功能接口5、功能接口6和功能接口7,即功能接口5-7会发生冲突,处理策略是拒绝通过功能接口5和功能接口6发送的请求,处理通过功能接口7发送的请求。
若客户端通过功能接口3发送请求,功能接口3不在冲突检测接口列表中,判断通过功能接口3发送的请求通过冲突验证。
若客户端通过功能接口6发送请求,功能接口6在冲突检测接口列表中,且处理策略为拒绝通过功能接口6发送的请求,则通过功能接口6发送的请求不通过冲突验证。
若客户端通过功能接口7发送请求,功能接口7在冲突检测接口列表中,且处理策略为处理(即不拒绝)通过功能接口7发送的请求,则通过功能接口7发送的请求通过冲突验证。
在本公开的一些可选实施例中,所述至少一个功能接口包括以下至少之一:
数据采集任务配置接口、命令下发接口、参数配置管理接口、无线资源管理算法下发接口和无线资源管理策略下发接口;
所述北向接口请求处理功能单元,用于接收所述客户端通过所述数据采集任务配置接口发送的数据采集任务配置信息和数据上报任务配置信息;向所述数据采集子模块发送所述数据采集任务配置信息,触发所述数据采集上报子模块进行数据采集;向所述数据上报子模块发送所述数据上报任务配置信息,触发所述数据上报子模块上报采集的数据;和/或,
接收所述客户端通过所述命令下发接口发送的请求;根据所述请求中调用命令的标识,触发所述功能层中与所述标识对应的功能模块运行,并向所述与所述标识对应的功能模块发送所述请求中所述调用命令的参数;和/或,
接收所述客户端通过所述参数配置管理接口发送的参数配置信息;向所述配置管理子模块发送所述参数配置信息,触发所述配置管理子模块根据所述参数配置信息,进行参数更新;和/或,
接收所述客户端通过所述无线资源管理算法下发接口发送的无线资源管理算法软件;向所述无线资源管理功能模块发送所述无线资源管理算法软件,触发所述无线资源管理功能模块进行算法软件的更新;和/或,
接收所述客户端通过所述无线资源管理策略下发接口发送的无线资源管理策略;向所述无线资源管理功能模块发送所述无线资源管理策略,触发所述无线资源管理功能模块进行算法策略的更新。
具体来说,客户端通过一功能接口发送请求,会触发与该功能接口相对应的中心单元功能层中的功能模块运行。
客户端通过各功能接口发送请求,触发的功能模块对应如下:
1)数据采集任务配置接口:对应数据采集子模块和数据上报子模块。
2)命令下发接口:对应功能层中与请求中调用命令的标识对应的功能模块。
3)参数配置管理接口:对应配置管理子模块。
4)无线资源管理算法下发接口:对应无线资源管理功能模块。
5)无线资源管理策略下发接口:对应无线资源管理功能模块。
在本公开的一些实施例中,中心单元能力开放层中的每一功能接口和/或每一验证接口可以为一实体接口。
举例来说,中心单元能力开放层中有数据采集任务配置接口、命令下发接口、参数配置管理接口、无线资源管理算法下发接口和无线资源管理策略下发接口这5个功能接口,以及,冲突策略下发接口和权限管理配置接口这2个验证接口,每一功能接口和每一验证接口都是实体接口。
在本公开的一些实施例中,中心单元能力开放层中可以包括预设个数的实体接口,每一实体接口能够执行至少一个功能接口和/或至少一个验证接口的功能。
举例来说,中心单元能力开放层包括7个实体接口,为5个功能接口:数据采集任务配置接口、命令下发接口、参数配置管理接口、无线资源管理算法下发接口和无线资源管理策略下发接口,以及,2个验证接口:冲突策略下发接口和权限管理配置接口,每个实体接口都分别执行该接口的功能。
又如:中心单元能力开放层包括1个实体接口,该接口可以执行数据采集任务配置接口、命令下发接口、参数配置管理接口、无线资源管理算法下发接口和无线资源管理策略下发接口这5个功能接口的功能,以及,冲突策略下发接口和权限管理配置接口这2个验证接口的功能。
再如:中心单元能力开放层包括3个实体接口,接口1可以执行数据采集任务配置接口的功能,接口2可以执行无线资源管理算法下发接口和无线资源管理策略下发接口的功能,接口3可以执行冲突策略下发接口和权限管理配置接口这2个验证接口的功能。
本公开实施例的无线接入网中心单元,不仅可以分离对外的功能接口,还能够扩展功能接口,即,可以在中心单元能力开放层中增加新的功能接口,或者,在中心单元能力开放层中的功能接口中增加新的功能。更为灵活方便,且不影响底层功能。
请参阅图2,图2是本公开实施例的通信结构示意图。如图2所示,包括客户端21和无线接入网中心单元22,其中,该无线接入网中心单元22包括:中心单元功能层221和与中心单元功能层221连接的中心单元能力开放 层222。中心单元功能层221包括:控制面协议功能模块2211、用户面协议功能模块2212、无线资源管理功能模块2213和运维管理功能模块2214。中心单元能力开放层222包括功能接口2221,即,中心单元能力开放层222可支持中心单元功能层221中相关功能模块的配置、管理和调用,并对外部提供相关北向接口(即功能接口2221)。客户端21通过功能接口2221与无线接入网中心单元22连接,客户端21通过功能接口2221触发中心单元功能层221中的一个或多个功能模块运行。
请参阅图3,图3是本公开实施例的客户端和无线接入网中心单元进行通信的流程示意图。客户端和无线接入网中心单元的通信流程包括以下步骤:
第一步:客户端通过功能接口发送请求。
客户端可以通过中心能力开放层的API发送请求。
第二步:中心单元能力开放层进行身份认证、权限确认、冲突验证,针对具有调用功能接口权限的客户端发送的、且通过冲突验证的请求,进行功能映射。
即,中心单元能力开放层包括:权限管理功能单元和北向接口请求冲突协调功能单元。权限管理功能单元对调用功能接口的客户端进行身份认证,根据客户端的身份,确认客户端是否有被调用的功能接口的调用权限;若客户端有调用权限,将请求发送至北向接口请求冲突协调功能单元。北向接口请求冲突协调功能单元根据被客户端调用的功能接口,对请求进行冲突验证;针对通过验证的请求,可以将客户端发送的请求映射为触发中心单元功能层中的相应功能模块运行的功能调用请求,并发送至相应功能模块,触发相应功能模块运行,如:进行数据采集、参数配置管理和命令下发等操作。
第三步:中心单元功能层中的相应功能模块运行,生成与请求对应的回复信息,并返回至中心单元能力开放层。
相应功能模块可以生成并发送与请求对应的功能调用回复信息。
第四步:中心单元能力开放层接收相应功能模块发送的请求的回复信息,通过功能接口向客户端发送。
中心单元能力开放层根据接收的功能调用回复信息,生成API请求的回复信息,通过API接口向客户端发送。
