Description

一种功能调度方法、设备和系统 技术领域
本发明涉及通信领域,尤其涉及一种功能调度方法、设备和系统。
背景技术
控制面用户面分离(Control and User Plane Separation,CUPS)是核心网网络架构的一个发展趋势,由不同的功能实体分别执行用户面(User Plane,UP)和控制面(英文Control Plane,CP)功能,随着网络实体被划分为用户面网元和控制面网元,一些主要功能也需要划分由谁支持。如表1所示的控制面网元和用户面网元对于现有网络功能的支持情况中,部分功能仅由控制面网元或用户面网元支持,但是部分功能是控制面网元和用户面网元都能支持的。针对控制面网元和用户面网元都能支持的功能,在具体的网络中需要确定由谁来执行这个功能。
表1
仅控制面网元支持 仅用户面网元支持 用户面网元和控制面网元均支持
信令处理 数据转发 数据缓存
话单生成 数据统计 用户面隧道地址分配
用户IP地址分配 报文marking 报文重定向
现有技术中,通过运营商设备的配置来确定由控制面网元还是用户面网元来执行控制面网元和用户面网元都可以支持的共有功能。如图1A所示,运营商设备配置的方式为在硬件设备上设定好某些共有功能默认在控制面网元上执行,另外共有功能默认在用户面网元上执行,后续不再改变。
然而现有技术中,以运营商设备配置的方式提前设定一部分共有功能只能在控制面网元上执行或只能在用户面网元上执行,相当于将共有功能设置成固定由控制面网元或者用户面网元来执行,处理方式单一且灵活度低。
发明内容
本发明实施例提供了一种功能调度方法、设备和系统,用以灵活处理用户面网元和控制面网元都支持的功能。
一方面,本发明实施例提供一种功能调度方法。该方法包括:控制面网元向用户面网元发送第一请求,第一请求用于请求用户面网元执行第一功能,第一功能为控制面网元和用户面网元都支持的功能;用户面网元从控制面网元接收第一请求后,开启第一功能;控制面网元关闭第一功能。本发明实施例中,控制面网元利用用户面网元对第一功能的支持,将第一功能转移给用户面网元执行,动态调整网络资源,针对控制面网元和用户面网元都支持的功能,在执行处理上更为灵活。
在一个可能的设计中,控制面网元向用户面网元发送第一请求之前,控制面网元还可以获取自身当前的负载或者位置信息,位置信息包括用户面网元的位置信息和终端的位置信息;然后,控制面网元可以根据控制面网元当前的负载或位置信息,确定需要向用户面网元发送第一请求。
在一种可能的实施方式中,控制面网元获取用户面网元的位置信息和终端的位置信息后,可以得到第一距离和第二距离,其中,第一距离为控制面网元到终端的距离,第二距离为用户面网元到终端的距离。控制面网元根据位置信息确定需要向用户面网元发送第一请求可以通过以下方式实现:控制面网元根据位置信息比较第一距离和第二距离;若第一距离大于第二距离,则控制面网元确定需要向用户面网元发送第一请求。
在上述实施方式中,控制面网元可以通过以下方式获取位置信息:控制面网元可以从终端接收终端的位置信息;控制面网元可以从用户面网元接收用户面网元的位置信息,或者,控制面网元可以从本地获取用户面网元的位置信息。
在另一种可能的实施方式中,控制面网元根据控制面网元当前的负载确定需要向用户面网元发送第一请求可以通过以下方式实现:若控制面网元当前的负载达到或者超过第一门限值,则控制面网元确定需要向用户面网元发送第一请求。这种方式中,控制面网元自身负载过高的情况下,可以请求用户面网元开启第一功能。
在一个可能的设计中,控制面网元根据控制面网元当前的负载的信息或位 置信息确定需要向用户面网元发送第一请求之后,控制面网元向用户面网元发送第一请求之前,控制面网元还可以确定用户面网元支持第一功能。本发明实施例中,控制面网元能够在确定用户面网元支持第一功能的情况下,再向用户面网元发送第一请求,从而能够确保第一功能成功转移到用户面网元执行。
在一种可能的实施方式中,控制面网元确定用户面网元支持第一功能之前,还可以从用户面网元接收第一功能列表,第一功能列表包括用户面网元支持的所有功能;或者,控制面网元可以在本地查询得到第二功能列表,第二功能列表包括用户面网元支持的所有功能或包括控制面网元和用户面网元都支持的所有功能。在这种实施方式中,若第一功能列表或第二功能列表中包括第一功能,则控制面网元可以确定用户面网元支持第一功能。
在一个可能的设计中,控制面网元确定用户面网元支持第一功能后,还可以从用户面网元接收用户面网元的动态负载状态的信息,并根据用户面网元的动态负载状态确定用户面网元的可用资源;以及可以确定第一功能所占用的资源;若用户面网元的可用资源大于第一功能所占用的资源,则控制面网元可以确定用户面网元当前具备执行第一功能的能力。
在一种可能的实施方式中,控制面网元从用户面网元接收用户面网元的动态负载状态的信息之前,控制面网元还可以向用户面网元发送第一周期指令,第一周期指令用于指示用户面网元每隔一个预置周期向控制面网元上报所述用户面网元的动态负载状态的信息;或者,控制面网元还可以向用户面网元发送负载请求,负载请求用于指示用户面网元上报用户面网元的动态负载状态的信息。
在一个可能的设计中,控制面网元确定用户面网元当前具备执行第一功能的能力之后,控制面网元还可以获取第一功能对应的第一标识信息,第一标识信息包括用户标识、隧道标识或业务标识,第一请求携带有第一标识信息;然后,控制面网元可以根据标识信息和优先级等级关系确定第一标识信息的优先级;进而,控制面网元可以根据第一标识的优先级和预置的优先级执行方式确定,第一功能由用户面网元执行。本发明实施例中,控制面网元根据第一标识信息确定了第一标识信息的的优先级,并根据预置的优先级执行方式找出了第 一功能的执行方式,确定第一功能由用户面网元执行。考虑了实际应用中的特定场景,使本发明实施例在实际操作中更加完善。
本发明实施例所涉及的第一功能可以包括以下至少一项:数据缓存功能、用户面隧道地址分配功能或报文重定向功能。
在一个可能的设计中,第一功能为用于分配地址的功能,用户面网元开启第一功能后,还可以根据第一功能更新本地存储的可分配地址信息。或者,用户面网元还可以向运营商设备发送地址分配指令;并接收所述运营商设备发送的可分配地址。
在一个可能的设计中,第一功能为用于数据缓存的功能,用户面网元从控制面网元接收第一请求之前,还可以从控制面网元或者运营商设备接收第二周期指令,第二周期指令用于指示用户面网元每隔一个预置周期向所述控制面网元上报用户面网元的动态负载状态的信息;或者,用户面网元还可以从控制面网元接收负载请求,负载请求用于指示用户面网元上报用户面网元的动态负载状态的信息。对应的,用户面网元在接收第二周期指令或负载请求之后,可以向控制面网元发送用户面网元的动态负载状态的信息。
在一个可能的设计中,用户面网元可以根据用户面网元的动态负载状态的信息和第一功能,确定开启第一功能。
在一种可能的实施方式中,用户面网元可以确定第一功能所占用的资源的值;若根据第一功能所占用的资源的值和用户面网元的动态负载状态的信息确定用户面网元开启第一功能后的负载不超过第二门限值,则用户面网元可以确定开启第一功能。例如,用户面网元可以根据用户面网元的动态负载状态的信息获取用户面网元当前的已用资源的值;然后,用户面网元将已用资源的值与第一功能所占用的资源的值进行加法运算得到第一数值;若第一数值小于预设的已用资源的值,则用户面网元可以确定自身开启第一功能后的负载不超过第二门限值。又例如,用户面网元可以根据用户面网元的动态负载状态的信息获取用户面网元当前的剩余资源的值;然后,用户面网元将剩余资源的值与第一功能所占用的资源的值进行减法运算得到第二数值;若第二数值大于预设的剩余资源的值,则用户面网元可以确定自身开启所述第一功能后的负载不超过第 二门限值。
另一方面,本发明实施例提供了另一种功能调度方法。该方法包括:用户面网元向控制面网元发送第二请求,第二请求用于请求控制面网元执行第二功能,第二功能为控制面网元和用户面网元都支持的功能;控制面网元从用户面网元接收第二请求之后,开启第二功能;用户面网元关闭第二功能。
在一个可能的设计中,用户面网元向控制面网元发送第二请求之前,还可以根据用户面网元当前的负载确定需要向控制面网元发送第二请求。例如,用户面网元可以获取用户面网元当前的负载;若该当前的负载超过第三门限值,则用户面网元确定需要向控制面网元发送第二请求。
在一个可能的设计中,第二请求可以携带用户面网元的动态负载状态的信息,控制面网元从用户面网元接收第二请求之后,还可以根据第二请求确定用户面网元当前执行的所有功能;控制面网元在用户面网元当前执行的所有功能中确定第二功能。或者,第二请求可以携带第二功能的信息,控制面网元可以根据第二请求确定第二功能。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,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描述。
本发明实施例描述的网络架构以及业务场景是为了更加清楚的说明本发明实施例的技术方案,并不构成对于本发明实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本发明实施例提供的技术方案对于类似的技术问题,同样适用。
图1B为本发明实施例提供的一种可能的网络架构的示意图,其中,该网络架构是一种控制面用户面分离的网络架构。图1B中,终端通过接入网接入到核心网,其中,终端可以是用户设备(User Equipment,UE),接入网可以是下一代无线接入网(Next Generation Radio Access Network,NG-RAN),核心网可以包括控制面网元和用户面网元等,其中,控制面网元可以是下一代控制面(Next Generation Control Plane,NG-CP)网元,用户面网元可以是下一代用户面(Next Generation User Plane,NG-UP)网元。NG-CP网元与应用功能(AF,Application Function)实体相连,该AF实体是提供应用业务的单元,主要对IP-CAN用户面行为进行动态策略/计费控制。NG-CP网元还与统一数据管理(Unified Data Manager,UDM)平台相连,以执行能力开放功能(Capability Exposure Function,CEF),来实现按目的地配置的负载平衡和按数据包配置的负载平衡。NG-UP网元与数据网络(DataNetwork)相连,以对数据进行处理。
对于用户面和控制面都支持的功能,现有技术中,通过运营商的配置来确定由用户面还是控制面来执行。然而,这种方式使得用户面网元和控制面网元都支持的功能只能固定在控制面上执行或只能固定在用户面上执行,处理方式单一且灵活度低。
有鉴于此,本发明实施例提供一种功能调度方法,以及基于这个方法的控 制面网元、用户面网元和系统。该方法包括:控制面网元向用户面网元发送第一请求,该第一请求用于请求用户面网元执行第一功能,该第一功能为控制面网元和用户面网元都支持的功能;然后,用户面网元开启第一功能;控制面网元关闭第一功能。本发明实施例的方案中,控制面网元可以将第一功能,即控制面网元和用户面网元都支持的功能,转移给用户面网元执行,从而能够动态调整网络资源,更为灵活地处理控制面网元和用户面网元都支持的功能。例如,上述功能调度方法可以如图2所示。
201、控制面网元向用户面网元发送第一请求。
具体的,控制面网元在执行多个功能时,为了保证系统的正常稳定或者更高效的运行,控制面网元可以将部分功能转移给用户面网元执行。在转移功能前,控制面网元向用户面网元发送第一请求,该第一请求用于请求用户面网元执行第一功能,可以理解的是,第一功能为控制面网元和用户面网元都支持的功能。
202、用户面网元开启第一功能。
具体的,由于第一请求用于请求用户面网元执行第一功能,用户面网元通过该第一功能获知到控制面需要转移的功能,然后,用户面网元接收到控制面网元发送的第一请求后,用户面网元开启该第一功能。
203、控制面网元关闭第一功能。
具体的,控制面网元可以在确定用户面网元开启第一功能后,将该第一功能关闭。
本发明实施例中,控制面网元可以将第一功能,即控制面网元和用户面网元都支持的功能,转移给用户面网元执行,从而能够动态调整网络资源,更为灵活地处理控制面网元和用户面网元都支持的功能。
本发明实施例中,上述第一功能可以包括用于分配地址的功能和/或用于数据缓存的功能,控制面网元可以根据位置信息或控制面网元当前的负载确定向用户面网元发送第一请求,以请求用户面网元执行第一功能。可以理解的是,在执行本发明实施例的方案前,控制面网元当前在执行第一功能。在实际应用中,第一功能也可以称为共有功能或公用功能,对此本发明实施例不作限定。
从上文可以看到,第一功能所包括的功能可能有以下不同情况:
第一种情况:第一功能包括用于分配地址的功能和用于数据缓存的功能;
第二种情况:第一功能仅包括用于数据缓存的功能;
第三种情况:第一功能仅包括用于分配地址的功能。
下面结合图3~图6对本发明实施例的方案做进一步介绍。其中,图3示出了第一种情况下的功能调度方法;图4和图5示出了第二种情况下的功能调度方法;图6示出了第三种情况下的功能调度方法。
请参阅图3,本发明实施例中功能调度方法一个实施例包括:
301、控制面网元从用户面网元接收第一功能列表。
当控制面网元在执行多个功能且需要将用户面网元也支持的功能转移给用户面网元时,控制面网元应获知用户面网元支持的功能。控制面网元接收用户面网元发送的第一功能列表,其中该第一功能列表包括用户面网元支持的所有功能,使得控制面网元通过该第一功能列表能确定控制面网元和用户面网元都支持的功能。
其中,本发明实施例中,控制面网元包括会话管理网元、移动性管理网元、策略功能网元、能力开放网元、鉴权授权网元等,用户面网元包括接入网关、移动性网关、本地网关、锚点网关等,具体此处不做限定。
需要说明的是,在实际应用中,控制面网元除了通过接收用户面网元发送的第一功能列表来获知用户面网元支持的功能外,控制面网元获知用户面网元支持的功能的方式还有多种,例如控制面网元可以在本地查询得到第二功能列表,其中该第二功能列表由运营商设备预先配置保存在本地,第二功能列表包括用户面网元支持的所有功能,使控制面网元通过第二功能列表获知用户面网元支持的功能。另外,还可以运营商配置的第二功能列表直接包括控制面网元和用户面网元都支持的所有功能,使控制面网元可以通过第二功能列表直接获知控制面网元和用户面网元都支持的功能,故控制面网元获知用户面网元支持的功能的方式具体此处不做限定。
可以理解的是,用户面网元除了以表格的形式将第一功能列表发送给控制面网元,第一功能列表还可以为文本、列格式或者信息的形式,故第一功 能列表的形式具体此处不做限定。
302、控制面网元获取自身当前的负载。
负载,即为某个设备所负担的流量或用户量等,负载高则代表剩余的可用资源少,当负载过高时,会导致系统运行速度变慢甚至关闭,由于控制面网元和用户面网元都支持的功能中包括用于数据缓存的功能,且执行用于数据缓存的功能时会占用较多的系统可用资源,为了保证系统能够持续正常工作和系统资源的合理利用,故控制面网元获取自身当前的负载以确定需要向用户面网元发送第一请求,以请求将该用于数据缓存的功能转移给用户面网元执行。
需要说明的是,在实际应用中,用户面网元和控制面网元都支持且用于数据缓存的功能包括报文缓存功能或数据缓存功能等,具体此处不做限定。
303、控制面网元从终端接收终端的位置信息。
由于用户面和控制面分离之后,一种可能的情况是控制面网元部署在较高的位置,而用户面网元里终端更近,因此选择离终端更近的用户面网元来执行分配地址的功能,信息需要传输的路径比由控制面网元完成该功能要更近,终端与用户面网元之间能够迅速建立连接完成相应的功能。故为了保证系统以更优化的路径完成相应的功能,控制面网元通过位置信息确定将用于分配地址的功能转移给用户面网元执行。
其中,位置信息包括终端的位置信息和用户面网元的位置信息,且控制面网元获得终端的位置信息的方式为终端将其位置信息上报给控制面网元而实现。需要说明的是,控制面网元接收终端上报的终端的位置信息,可以由控制面网元实时向终端发送位置指令以指示终端上报其位置信息,使得终端根据该位置指令上报其位置信息,还可以由控制面网元向终端发送周期指令以指示终端每隔一个预置周期向控制面网元上报其当前的位置信息,使得终端根据该周期指令向控制面网元发送终端的位置信息,故触发终端向控制面网元发送终端的位置信息的方式具体此处不做限定。
需要说明的是,在实际应用中,用户面网元和控制面网元都支持且用于分配地址的功能包括动态主机配置(Dynamic Host Configuration Protocol, DHCP)功能、用户面隧道地址分配功能或报文重定向功能等,具体此处不做限定。
304、控制面网元从用户面网元接收用户面网元的位置信息。
位置信息包括终端的位置信息和用户面网元的位置信息,控制面网元接收用户面网元发送的用户面网元的位置信息,其中用户面网元的位置信息包括用户面网元的所在的位置或者用户面网元服务的范围。
需要说明的是,在实际应用中,控制面网元获得用户面网元的位置信息的方式除了由用户面网元发送,还有其他方式,例如运营商设备预先将用户面网元的位置信息存储在本地,使控制面网元可以从本地直接获取用户面网元的位置信息,故控制面网元获得用户面网元的位置信息的方式具体此处不做限定。
另外,本发明实施例中,控制面网元通过步骤303获得终端的位置信息,通过步骤304获得用户面网元的位置信息,而这两个过程之间并不存在步骤的先后顺序,可以先执行步骤303,也可以先执行步骤304,或者同时执行,具体此处不做限定。
305、控制面网元根据位置信息比较第一距离和第二距离。
控制面网元获得终端的位置信息和用户面网元的位置信息,且控制面网元知道自身的位置信息,可得到第一距离和第二距离,其中第一距离为控制面网元和终端的距离,第二距离为用户面网元和终端的距离。控制面网元比较第一距离和第二距离的大小以确定需要向用户面网元发送第一请求,以请求将本实施例中第一功能包括的用于分配地址的功能转移给用户面网元执行。
需要说明的是,本发明实施例中,控制面网元通过步骤301获得第一功能列表,通过步骤302获取自身当前的负载以确定需要向用户面网元发送第一请求,通过步骤303至305获得位置信息需要向用户面网元发送第一请求,而这三个过程之间并不存在步骤的先后顺序,可以最先执行步骤302、再执行步骤303至305,最后执行步骤301,也可以先执行步骤303至305,再执行步骤301,最后执行步骤302,或者同时执行,具体此处不做限定。
306、控制面网元确定需要向用户面网元发送第一请求。
当控制面网元获得位置信息或控制面网元当前的负载后,则控制面网元根据位置信息或控制面网元当前的负载确定需要向用户面网元发送第一请求。
当第一距离大于第二距离时,即控制面网元到终端的距离比用户面网元到终端的距离远时,控制面网元确定需要向用户面网元发送第一请求,其中第一请求用于请求用户面网元执行用于分配地址的功能。
需要说明的是,当第一距离不大于第二距离时,即控制面网元到终端的距离不大于用户面网元到终端的距离时,则还是由控制面网元执行该用于分配地址的功能。
当控制面网元当前的负载达到或者超过第一门限值时,控制面网元确定需要向用户面网元发送第一请求,其中第一请求用于请求用户面网元执行用于数据缓存的功能。
需要说明的是,若控制面网元自身当前的负载小于剩余可用资源占全部可用资源的比值,则控制面网元确定自身当前的负载达到或者超过第一门限值。实际应用中,还可以设定若控制面网元自身当前的负载大于已用资源占全部可用资源的比值或控制面网元自身当前的负载小于剩余可用资源的值,则控制面网元确定自身当前的负载达到或者超过第一门限值。故控制面网元确定自身当前的负载达到或者超过第一门限值的方式此处不做限定。
可以理解的是,若控制面网元确定自身当前的负载小于第一门限值,则控制面网元不需要向用户面网元发送第一请求。
307、控制面网元确定用户面网元支持第一功能。
控制面网元获得了第一功能列表后,由于第一功能列表中包括用户面网元支持执行的所有功能,故控制面网元在第一功能列表中找出自身也支持执行的功能,故控制面网元确定控制面网元和用户面网元都支持的所有功能,在实际应用中,控制面网元和用户面网元都支持的所有功能包括数据缓存功能、用户面隧道地址分配功能、报文重定向功能或报文缓存功能等。控制面网元在该控制面网元和用户面网元都支持的所有功能中找出第一功能,进而确定用户面网 元支持第一功能,其中第一功能至少包括控制面网元和用户面网元都支持的所有功能中的一项。
308、用户面网元接收控制面网元发送的负载请求。
控制面网元确定需要向用户面网元发送第一请求以转移用于缓存数据的功能时,用户面网元接收控制面网元发送的负载请求以向控制面网元发送用户面网元的动态负载状态的信息,进而让控制面网元确定用户面网元当前具备执行第一功能的能力。
需要说明的是,用户面网元向控制面网元上报自身动态负载状态信息的触发方式除了包括接收CO发送的负载请求,在实际应用中,还有多种方式能触发用户面网元向控制面网元上报自身动态负载状态信息,例如用户面网元接收控制面网元或者运营商设备发送的第一周期指令,该第一周期指令指示用户面网元每隔一个预置周期向控制面网元上报用户面网元的动态负载状态的信息,故使得用户面网元周期性向控制面网元上报自身的动态负载状态的信息。因此,触发用户面网元向控制面网元上报自身动态负载状态信息的方式具体此处不做限定。
309、用户面网元向控制面网元发送用户面网元的动态负载状态的信息。
用户面网元接收控制面网元发送的负载请求后,用户面网元向控制面网元发送用户面网元的动态负载状态的信息,即用户面网元当前的负载状态的信息,以让控制面网元确定用户面网元当前具备执行第一功能的能力。
需要说明的是,由于实际应用中,可以由用户面网元接收控制面网元发送的负载请求后再被动向控制面网元发送用户面网元的动态负载状态的信息,也可以由用户面网元接收控制面网元或者运营商设备发送的第一周期指令后再主动周期性向控制面网元上报自身的动态负载状态的信息,故用户面网元向控制面网元发送用户面网元的动态负载状态的信息的方式具体此处不做限定。
310、控制面网元获取第一功能占用的资源和用户面网元的可用资源。
控制面网元确定用户面网元支持第一功能后,由于第一功能中包括用于数据缓存的功能,且该功能执行时占用极大的系统资源,故控制面网元在确定向用户面网元转移第一功能前,会考察用户面网元当前的负载是否支持执行第一 功能。
控制面网元接收用户面网元发送的用户面网元的动态负载状态的信息后,在该用户面网元的动态负载状态的信息中确定用户面网元的可用资源,且控制面网元确定第一功能所占用的资源,以根据用户面网元的可用资源和第一功能占用的资源来确定用户面网元当前具备执行第一功能的能力。
311、控制面网元确定用户面网元当前具备执行第一功能的能力。
控制面网元获取第一功能占用的资源和用户面网元的可用资源后,将该第一功能占用的资源与用户面网元的可用资源进行比较,若用户面网元的可用资源大于第一功能占用的资源,则控制面网元确定用户面网元当前具备执行第一功能的能力。
可以理解的是,若用户面网元的可用资源不大于第一功能占用的资源,则控制面网元确定用户面网元当前并不具备执行第一功能的能力。
需要说明的是,控制面网元除了根据第一功能占用的资源和用户面网元的可用资源确定用户面网元当前具备执行第一功能的能力外,实际应用中,控制面网元还可根据多种方式确定用户面网元当前具备执行第一功能的能力。如控制面网元在用户面网元的动态负载状态的信息中确认用户面网元的已用资源,将该已用资源与第一功能占用的资源相加得到第三数值,若该第三数值小于预置门限值,则控制面网元确定用户面网元当前具备执行第一功能的能力,其中该预置门限值表示若已用资源超过该预置门限值,则系统处于超负载运行状态。故控制面网元确定用户面网元当前具备执行第一功能的能力的方式具体此处不做限定。
另外,在实际应用中,存在一些情况,如控制面网元需要转移的用于数据缓存的第一功能有多个,而控制面网元获取第一功能占用的资源和用户面网元的可用资源后,确定用户面网元仅支持多个用于数据缓存的功能中的一部分,故控制面网元在确保用户面网元执行第一功能后不处于超负载运行状态的前提下,随机选择部分用于数据缓存的功能来作为第一功能由用户面网元执行,或者按照预置的选择规则从中选择部分用于数据缓存的功能来作为第一功能由用户面网元执行,其中预置的选择规则包括终端标识优先级或业务标识优先 级等,此处不做具体限定。
312、控制面网元根据标识信息和优先级等级关系确定第一标识信息的优先级。
在实际应用中,为了保证重要的用户通过终端能持续稳定使用功能或者用户在执行紧急业务时不被影响,会将功能所对应的用户标识或者业务标识等按照优先级进行分类,以更好的提供服务。由于负载过高会导致系统运行速度变慢或者关闭,因此当控制面网元负载过高,需要转移消耗负载较大的功能如用于数据缓存的功能时,若该功能对应的优先级别越高,控制面网元越会优先保证其稳定性。
当控制面网元确定用户面网元支持第一功能后,获取第一功能对应的第一标识信息,且第一标识信息携带于第一请求中,以告知用户面网元第一功能的第一标识信息。控制面网元再从本地存储的标识信息和优先级等级关系中找出第一标识信息的优先级,以确定第一功能由用户面网元还是控制面网元执行。
需要说明的是,实际应用中,第一标识信息包括用户标识、隧道标识或业务标识等,在实际应用中可以具体为国际移动用户识别码(Intemational Mobile Subscriber Identification Number,IMSI)、接入点名称(Access Point Name,APN)或UE type等,具体此处不做限定。
可以理解的是,标识信息和优先级等级关系可以通过列形式、文档的格式或者K-V格式存储于本地数据库中,在实际应用中,也可以直接体现在标识信息中,例如,报文重定向功能对应的用户标识中带有优先级标号1,控制面网元按照约定的规则,判断带有优先级标号1的用户标识即为高优先级用户,即确定了该报文重定向功能的用户标识的优先级。因此标识信息和优先级等级信息的体现方式具体此处不做限定。
在预置的标识信息与优先级等级关系中确定第一功能对应的标识信息的优先级,其中,标识信息包括终端标识、业务标识或者用户面通道标识等,具体此处不做限定。
313、控制面网元根据第一标识信息的优先级和预置的优先级执行方式确定第一功能由用户面网元执行。
控制面网元确定第一标识信息的优先级后,由于在预置的优先级执行方式中包括标识信息、标识信息的优先级和执行方式,故控制面网元可以从中找出第一功能对应的执行方式并确定第一功能由用户面网元执行。
其中,可以理解的是,在实际应用中,在配置优先级执行方式时,可以为在CP系统负载过高的情况下,标识信息的优先级高于特定等级时,只能由控制面网元执行;或在CP系统负载过高的情况下,标识信息的优先级高于特定等级时,优先转移给用户面网元执行。故预置的优先级执行方式具体此处不做限定。
需要说明的是,优先级执行方式可以通过列形式或者文档格式存储于本地数据库中,在实际应用中,还可以直接根据优先级得到,例如,控制面网元确定了缓存功能对应的用户标识的优先级为高优先级,控制面网元按照运营商设备预设的规则默认高优先级用户所使用的功能由控制面网元执行,则该缓存功能依旧由控制面网元执行。因此,优先级执行方式的体现形式具体此处不做限定。
314、控制面网元向用户面网元发送第一请求。
控制面网元确定第一功能由用户面网元执行后,向用户面网元发送第一请求,以指示用户面网元执行第一功能。
可以理解的是,第一请求用于请求用户面网元执行第一功能,即用户面网元通过第一请求即可知道第一功能包括哪些功能,其中,控制面网元可以在第一请求中携带第一功能的名称,如报文重定向功能、用户面隧道地址分配功能或者DHCP功能等,也可以在第一请求中携带第一功能的标识代码,如A代表报文重定向功能,B代表用户面隧道地址功能等,因此用户面网元通过第一请求中的标识代码即可确定第一功能,其中该标识代码为用户面网元和控制面网元共同约定的。因此,第一功能的表示方式具体此处不做限定。
315、用户面网元确定第一功能所占用的资源的值。
用户面网元接收到控制面网元发送的第一请求后,由于该第一请求中包括用于数据缓存的功能,且用户面网元向控制面网元发送自身动态负载信息的时间与UP接收控制面网元发送的第一请求的时间不一致,因此用户面网元的动 态的负载信息也可能发生变化,故用户面网元需根据用户面网元的动态的负载信息和第一功能所占用的资源的值确定自身当前具备执行第一功能的能力。用户面网元接收到第一请求后,由于第一请求中携带有第一功能的信息,因而用户面网元可获取第一功能所占用的资源的值。
其中,需要说明的是,用户面网元除了通过第一请求获取第一功能所占用的资源的值,在实际应用中,还能由控制面网元将第一功能所占用的值以信息的方式发送给用户面网元,故,用户面网元获取第一功能所占用的值的方式具体此处不做限定。
316、用户面网元将自身当前的已用资源的值与第一功能所占用的资源的值进行加法运算。
用户面网元获取自身的动态的负载信息,并得到用户面网元当前的已用资源的值。用户面网元再将获得的第一功能所占用的资源的值与已用资源的值进行加法运算,得到第一数值,以确定用户面网元当前具备执行第一功能的能力。
317、用户面网元确定开启第一功能后的负载不超过第二门限值。
用户面网元将获得的第一功能所占用的资源的值与已用资源的值进行加法运算得到第一数值后,将第一数值与预设的已用资源的值进行比较,其中,预设的已用资源的值为用户面网元动态的已用资源的值超过该值时,用户面网元负载过高。故若第一数值小于预设的已用资源的值,则用户面网元确定开启第一功能后的负载不超过第二门限值。
可以理解的是,若第一数值不小于预设的已用资源的值,则用户面网元确定开启第一功能后的负载超过第二门限值,因此用户面网元拒绝执行第一功能中用于数据缓存的功能,仍由控制面网元执行。
其中,需要说明的是,用户面网元通过步骤315至步骤317确定用户面网元开启第一功能后的负载不超过第二门限值,实际应用中,用户面网元还可通过多种方式来确定,例如,用户面网元确定了第一功能所占用的资源的值,并由用户面网元的动态的负载信息获取其当前的剩余资源的值,用户面网元将剩余的资源的值与第一功能所占用的资源的值进行减法运算得到第二数值,将第二数值与预设的剩余资源的数值进行比较,其中,预设的剩余资源的值为用户 面网元动态的剩余资源的值不大于该值时,用户面网元负载过高。故第二数值小于预设的剩余资源的值,则用户面网元确定开启第一功能后的负载不超过第二门限值。因此,用户面网元确定自身确定开启第一功能后的负载不超过第二门限值的方式具体此处不做限定。
318、用户面网元开启第一功能。
由于第一功能中包括用于数据缓存的功能和用于分配地址的功能,用户面网元接收到第一请求后,即开启第一功能中用于分配地址的功能;且用户面网元确定开启第一功能后自身的负载不超过第二门限值后,则开启第一功能中用于数据缓存的功能。
319、用户面网元向控制面网元发送第一响应。
用户面网元开启第一功能后,向控制面网元发送第一响应,以通知控制面网元第一功能已开启,使控制面网元关闭第一功能。
320、控制面网元关闭第一功能。
控制面网元接收用户面网元发送的第一响应后,确定第一功能已转移给用户面网元执行,故控制面网元关闭第一功能。
321、用户面网元根据第一功能更新本地存储的可分配地址信息。
用户面网元开启第一功能后,在执行其中用于分配地址的功能时,由于本地存储的可分配地址信息有限,因此用户面网元分配地址后,将本地存储的可分配地址信息进行更新以防止重复分配。
需要说明的是,在实际应用中,用户面网元获得地址信息的方式还有多种,除了从本地获取获得地址信息,还包括用户面网元通过向运营商设备发送地址分配指令,而接受到由运营商设备发送的可分配地址。故用户面网元获得地址信息的方式具体此处不做限定。
本发明实施例中,控制面网元需要向用户面网元转移的功能包括用于分配地址的功能和用于数据缓存的功能,对于用于分配地址的功能,控制面网元确定用户面网元能支持该功能后即可向UP转移,对于用于数据缓存的功能,控制面网元确定当前自身的负载超过第一门限值,且用户面网元当前具备支持该功能的能力,故向用户面网元发送请求,当用户面网元也确定执行第一功能后 自身的负载不超过第二门限值后,用户面网元开启第一功能。本发明实施例中,控制面网元利用用户面网元对第一功能的支持,将第一功能转移给用户面网元执行,动态调整网络资源,针对不同作用的第一功能,在执行处理上更为灵活。
上述图3示出了第一种情况即第一功能包括用于分配地址的功能和用于数据缓存的功能的情况,下面图4和图5将第二种情况即第一功能仅包括用于数据缓存的功能的情况进行说明。

本发明实施例中,控制面网元确定用户面网元当前具备执行第一功能的能力后,再根据第一功能对应的标识信息的优先级确定第一功能由用户面网元执行,更加精细了对于控制面网元和用户面网元都支持的用于数据缓存功能的处理,增加了本发明实施例在实际应用中更具有针对性,增加了本发明实施例的实现方式。
上述图3示出了第一功能包括用于分配地址的功能和用于数据缓存的功能的情况,图4和图5示出了第一功能仅包括用于数据缓存的功能的情况,下面图6将对第一功能仅包括用于分配地址的功能的情况进行说明。
请参阅图6,本发明实施例中功能调度方法另一个实施例包括:

610、控制面网元关闭第一功能。
611、用户面网元根据第一功能更新本地存储的可分配地址信息。
本实施例中,步骤601、步骤602至步骤606、步骤607以及步骤609至步骤611,分别与图3的步骤301、步骤303至步骤307、步骤314以及步骤319至步骤321类似,具体实施过程可以参考图3中的详细描述,此处不再赘述。
本发明实施例中,当第一功能仅包括用于分配地址的功能时,控制面网元确定用户面网元能支持该功能后即可向用户面网元请求转移,用户面网元即开启第一功能,且在开启第一功能后,用户面网元再更新目前本地存储的可分配地址信息,使得系统能以更优化的路径完成相应的功能,也提高了系统的处理效率。
本发明实施例还提供另一种功能调度方法,以及基于这个方法的用户面网元、控制面和系统。该方法包括:用户面网元向控制面网元发送第二请求,该第二请求用于请求用户面网元执行第二功能,该第二功能为用户面网元和控制面网元都支持的功能;然后,控制面网元开启第二功能;用户面网元关闭第二功能。本发明实施例的方案中,用户面网元可以将第二功能,即控制面网元和用户面网元都支持的功能,转移给控制面网元执行,从而能够动态调整网络资源,更为灵活地处理控制面网元和用户面网元都支持的功能。例如,上述功能调度方法可以如图7所示。
本发明实施例中,上述第二功能可以包括用于数据缓存的功能,用户面网元可以根据用户面网元当前的负载确定向控制面网元发送第二请求,以请求控制面网元执行第二功能。可以理解的是,在执行本发明实施例的方案前,用户面网元正在执行第二功能。在实际应用中,第二功能也可以称为共有功能或公用功能,对此本发明实施例不作限定。
请参阅图7,本发明实施例中功能调度方法另一个实施例包括:701部分~707部分,其中,701部分、702部分、704部分和706部分为可选的部分。
701、用户面网元获取自身当前的负载。
当负载过高时,会导致系统运行速度变慢甚至关闭。由于控制面网元和用户面网元都支持的功能中包括用于数据缓存的功能,且执行用于数据缓存的功能时会占用较多的系统可用资源,为了保证系统能够持续正常工作和系统资源的合理利用,故用户面网元获取自身当前的负载以确定需要向控制面网元发送第二请求,以请求将该用于数据缓存的功能转移给用户面网元执行。
702、用户面网元确定当前的负载达到或者超过第三门限值。
用户面网元获取到自身当前的负载后,用户面网元确定当前的负载超过第三门限值。需要说明的是,若用户面网元自身当前的负载小于剩余可用资源占全部可用资源的比值,则用户面网元确定自身当前的负载达到或者超过第三门限值。实际应用中,还可以设定若用户面网元自身当前的负载大于已用资源占全部可用资源的比值或用户面网元自身当前的负载小于剩余可用资源的值,则用户面网元确定当前的负载超过第三门限值。故用户面网元确定自身当前的负载达到或者超过第三门限值的方式此处不做限定。
可以理解的是,若用户面网元确定自身当前的负载未达到第三门限值,则用户面网元可以不向控制面网元转移功能。
703、用户面网元向控制面网元发送第二请求。
用户面网元确定当前的负载达到或者超过第三门限值后,用户面网元向控制面网元发送第二请求,该第二请求用来请求控制面网元执行第二功能,其中第二功能为用户面网元正在执行且控制面网元也支持的功能。
需要说明的是,第二功能包括数据缓存功能、报文缓存功能或深度报文解析功能等,具体此处不做限定。
可以理解的是,第二请求用于请求控制面网元执行第二功能,即控制面网元通过第二请求即可知道第二功能包括哪些功能,其中,用户面网元可以在第二请求中携带第二功能的名称,如报文重定向功能、用户面隧道地址分配功能或者DHCP功能等,也可以在第二请求中携带第二功能的标识代码,如A代表报文重定向功能,B代表用户面隧道地址功能等,因此控制面网元通过第二请求中的标识代码即可确定第二功能,其中该标识代码为用户面网元和控制面网元共同约定的。因此,第二功能的表示方式具体此处不做限定。
704、控制面网元根据第二请求确定第二功能。
控制面网元接收用户面网元发送的第二请求后,由于第二请求中携带有第二功能的信息,故控制面网元可确定第二功能。
需要说明的是,在实际应用中,控制面网元确定第二功能的方式有多种,除了根据第二请求确定第二功能外,还可以在当第二请求中携带有用户面网元的动态负载状态的信息时,控制面网元根据该动态负载状态的信息确定用户面网元当前执行的所有功能,并从用户面网元当前执行的所有功能中确定控制面网元也能支持的第二功能,由于控制面网元和用户面网元都支持的功能中包括用于分配地址的功能和用于数据缓存的功能,在运行用于分配地址的功能时所消耗的资源较少,而在运营用于数据缓存的功能是所消耗的资源较多,故当用户面网元当前的负载达到或者超过第三门限值时,需要将消耗资源较多的用于数据缓存的功能转移给控制面网元执行,故在用户面网元负载过高的情况下,请求控制面网元执行的功能为用于数据缓存的功能。
可以理解的是,用户面网元也可以获得控制面网元的位置信息和终端的位置信息,若用户面网元与终端的距离大于控制面网元与终端的距离,则用户面网元也可以请求控制面网元执行用于分配地址的功能。即第二功能具体的类别此处不做限定。
705、控制面网元开启第二功能。
控制面网元根据第二请求确定第二功能后,控制面网元开使执行第二功能,以使用户面网元能关闭第二功能。
706、控制面网元发送第二响应给用户面网元。
控制面网元开启第二功能后,向用户面网元发送第二响应,以通知用户面网元第二功能已开启,使用户面网元关闭第二功能。
707、用户面网元关闭第二功能。
用户面网元接收控制面网元发送的第二响应后,确定第二功能已转移给控制面网元执行,故用户面网元关闭第二功能。
本发明实施例中,UP确定自身当前的负载超过第三门限值后,用户面网元向控制面网元发送第二请求,该第二请求用于请求控制面网元执行第二功 能,且第二功能为控制面网元和用户面网元都支持的功能,进而用户面网元关闭第二功能。本发明实施例中,用户面网元利用控制面网元对第二功能的支持,将第二功能转移给控制面网元执行,缓解了用户面网元的压力,动态调整网络资源。
