Description

一种中心单元切换的方法以及业务处理装置
本申请要求于2017年12月7日提交中国专利局、申请号为201711285461.8、发明名称为“一种中心单元切换的方法以及业务处理装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域,尤其涉及一种中心单元切换的方法以及业务处理装置。
背景技术
新一代的接入网的网络结构包括中心单元CU和分布单元DU,其中CU处理无线资源控制处理协议RRC、服务质量协议层SDAP和包数据汇聚处理协议PDCP协议层,DU则处理无线链路控制处理协议RLC、媒体接入控制处理协议MAC和物理层PHY协议。CU和DU之间通过标准的F1接口连接,具有部署灵活、CU可以使用通用处理硬件、具备通过F1异厂家对接的特点。
通常情况下,在新一代的接入网的架构中会采用单CU连接管理多DU的部署方式,但并不排除单DU连接多CU的部署方式,从可靠性角度,当一个CU故障时,DU连接到备用的CU上。在单DU连接多CU的部署方式下,若CU发生切换,对于分配DU侧的业务资源(RLC、MAC、PHY),目前较为常见的处理方式是在DU侧进行重新分配,UE与DU通过新的业务资源进行同步从而完成CU的切换过程。
以上对CU的切换过程中,而且由于DU内新旧无线资源发生切换,会造成数据的短暂中断,影响用户的体验。

具体实施方式
本申请实施例提供了一种中心单元切换的方法以及业务处理装置,用于实现在CU之间的切换过程中降低无线资源的开销。
为了使本技术领域的人员更好地理解本申请实施例方案,下面将结合本申请实施例中的附图,对本申请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申请一部分的实施例,而不是全部的实施例。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)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。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
请参考图1,为本申请实施例中的网络架构,包括基站和终端。
在本申请实施例中,基站即公用移动通信基站是无线电台站的一种形式,是指在一定的无线电覆盖区中,通过移动通信交换中心,与移动电话终端之间进行信息传递的无线电收发信电台。在本申请实施例中,一个基站可以服务一个或多个小区,所谓小区也称蜂窝小区,是指在蜂窝移动通信系统中,同一个基站所覆盖的区域,在这个区域内终端可以通过无线信道与基站进行通信。终端可以为包括手机、平板电脑、PDA(Personal Digital Assistant,个人数字助理)、POS(Point of Sales,销售终端)、车载电脑等任意终端设 备。以手机为例对终端的构造进行说明,包括:射频(Radio Frequency,RF)电路、存储器、输入单元、显示单元、传感器、音频电路、无线保真(wireless fidelity,WiFi)模块、处理器、以及电源等部件。本领域技术人员可以理解,该部分手机结构并不构成对手机的限定,可以包括比图示更多或更少的部件,或者组合某些部件,或者不同的部件布置。
在一些可行的实施例中,如图2所示,为基站内部的网络结构示意图,在该实施例中,基站可以内置一个CU和多个DU,如基站1内置CU1和DU1、DU2和DU3。其中,DU1、DU2和DU3分别服务不同的多个小区。
当下,新的接入网架构可以包括CU和DU,CU和DU可以灵活部署,具备通过F1接口与友商厂家对接的功能。一般情况下,在新的接入网架构中会采用单个CU连接管理多个DU的部署方式,但是也有可能使用单个DU连接多个CU的部署方式。
若是后者,当如图3所示(为UE从基站1切换至基站2的示意图),UE从连接基站1切换到连接基站2时,会发生CU的切换,如基站1的CU1切换至基站2的CU2,则原本由CU1服务的UE切换至CU2。若CU1和CU2共享DU1时,且UE一直被DU1服务,当CU发生切换时,对于分配DU侧的业务资源,常见的方式为在DU侧进行重新分配,以使得连接的UE与该DU1通过新的业务资源进行同步从而完成CU的切换过程(如图4所示,为UE从CU1切换至CU2的示意图)。
本申请实施例中,第一DU通过接收目标CU发送的关于第一业务的第一承载建立请求,该第一承载建立请求携带第一业务标识,并根据该第一业务标识确定是否需要为该第一业务分配业务资源,若确定不需要为该第一业务分配资源,在此次CU切换的过程中,只需要占用一份业务资源,而不需要占用2份业务资源,从而节省了CU的切换过程中的无线资源的开销,由于在切换的过程中不需要终端第一DU和UE的连接,因此UE无感知,数据无中断,从而增进了用户体验。
为便于理解,下面对本申请实施例中的具体流程进行描述,请参阅图5,为中心单元切换的方法的一个实施例,该方法包括:
501、该源CU向该第一DU发送关于第二业务的第二承载建立请求。
在本申请实施例中,当目标UE一个小区并发起第二业务时(如目标用户使用该目标UE打电话),若服务该小区的是源CU和第一DU,源CU需要为该目标UE服务并向服务该目标UE的DU指示该第二业务的业务资源,则该源CU确定该目标UE所处的小区,并根据该小区确定服务该目标UE的第一DU,并向该第一DU发送关于第二业务的第二承载建立请求,以使得源CU和该第一DU建立通信连接。在本申请实施例中,该第二业务可以为数据域业务或电路域业务,数据域业务如短信业务,电路域业务如呼叫业务,此处不做限定。
502、该第一DU为该第二业务分配第二业务资源。
在本申请实施例中,该第一DU为该第二业务提供第二业务资源,即第一DU的协议处理资源,具体包括RLC、MAC、PHY的协议层处理资源。需要说明的是,对于第一DU而言,一份业务资源在一个时间点上只能提供给一次业务,当该次业务结束后,该业务资源则可以空闲出来以供其他业务使用。在本申请实施例中,当该第一DU接收到源CU发送的第二承载建立请求时,在该第一DU有空闲的业务资源的情况下,可以为其分配第二业务资源,该第二业务资源用于提供该目标UE使用该第二业务。
503、该第一DU根据该第二业务生成第二业务标识,并以该第二业务标识为该业务标识集合中的一个。
在本申请实施例中,当该第一DU分配了第一业务资源后,可以为该第一业务确定一个标识,为第一标识,该第一标识作为该第一业务的唯一标识。在一些可行的实施例中,该第一标识可以包括用于指示第一业务资源的信息的标识、该第一业务开始进行的时间点等,此处不做限定。在本申请实施例中,当第一DU确定了第二业务标识后,可以将其作为业务标识集合中的一个业务标识,该业务标识集合中的任一个业务标识用于标识正在服务的业务。
504、该第一DU向该源CU发送第二承载建立响应,该第二承载建立响应包括该第二业务标识。
在本申请实施例中,当该第一DU确定了第一标识后,可以向源CU返回携带该第一标识的第二承载建立响应,则可以确定该源CU和该第一DU建立了通信连接。在本申请实施例中,当该源CU接收到该第二承载建立响应时,可以存储该第一标识,以备需要的时候使用。需要说明的是,该第一DU和该源CU可以通过F1接口连接,并在该F1接口上增加关于传送第一标识的信元,以使得该第一标识可以进行传送,此处不做限定。
505、源CU向目标CU发送关于第一业务的CU切换请求,该CU切换请求包括第一业务标识,该第一业务标识用于标识该第一业务。
在本申请实施例中,由于该源CU和该目标CU共享该第一DU,不同的CU和DU所服务的小区不尽相同,如目标CU和第一DU之间可能存在相同的服务的小区,也可能存在不同的服务的小区。如目标CU服务的小区为小区1/3/5/7/9,源CU服务的小区为2/4/6/8/10,第一DU服务的小区为1/2/3/4/5/6/7/8,若目标UE原来在源CU服务的小区2上,移动至目标CU服务的小区1上时,则会发生CU间的切换,即源CU会向目标CU发送CU切换请求,以使得该第一DU可以从与源CU的通信连接切换至于目标CU的通信连接。
在本申请实施例中,当发生CU间的切换时,源CU会生成关于服务UE的CU切换请求,该CU切换请求包括第一标识,并向目标CU发送该CU切换请求。在一些可行的实施例中,该源CU和目标CU并不会处理该第一标识,只是透传该第一标识,此处不做限定。
需要说明的是,在本申请实施例中,该源CU和目标CU通过Xn接口进行通讯连接,该Xn接口可以新增一个信元,该新增的信元被该源CU和该目标CU用于收发该第一标识。需要说明的是,新一代接入网基站之间的接口称之为Xn接口,CU之间通过Xn接口可以进行基站之间的通讯。
在一些可行的实施例中,目标CU和源CU可以通过下一代核心网(Next Generation Core,NGC)进行通信,如源CU向目标CU发送携带第一标识的该CU切换请求,可以为源CU向该NGC发送该CU切换请求,然后由该NGC向该目标CU发送该CU切换请求,反之,当该NGC接收到该目标CU发送给该源CU的信息,可以转发给源CU,此处不做限定。
506、该目标CU向第一DU发送关于该第一业务的第一承载建立请求,该第一承载建立请求包括该第一业务标识。
在本申请实施例中,当该目标CU接收到源CU的CU切换请求时,可以向该第一DU发送关于该第一业务的第一承载建立请求,该第一承载建立请求包括该源CU存储的第一标 识。需要说明的是,该目标CU可以根据该目标UE所在的小区确定该第一DU,如该目标UE从小区1移动到小区2,当目标CU接收到源CU的服务该UE的切换请求时,可以根据切换请求确定该UE所在的小区,则可以确定服务该小区的第一DU。
507、若业务标识集合包括该第一业务标识,该业务标识集合中的任一业务标识所指示的业务为该第一DU正在执行的业务,则该第一DU确定不需要为该第一业务分配业务资源;或者,若该业务标识集合不包括该第一业务标识,则该第一DU确定需要为该第一业务分配业务资源。
508、若确定需要为该第一业务分配业务资源,该第一DU为该第一业务分配第一业务资源。
在本申请实施例中,由于第一标识是第一业务的唯一标识,因此当该第一DU接收到第一承载建立请求时,可以确定该业务标识集合中是否包括第一标识,若有,则说明该第一DU正在服务该第一业务,则该第一DU不需要为该第一业务另外分配业务资源,而是可以继续使用正在服务该第一业务的业务资源,从而只需要占用一份业务资源,而不需要占用两份业务资源,从而节省了CU的切换过程中的无线资源的开销,而且由于目标UE不感知,不造成数据终端,从而提供了良好的用户体验。反之,若该业务标识集合中不包含该第一标识,则说明该第一DU并没有在服务该第一业务,则该第一DU需要另外重新为该第一业务分配业务资源。
509、该第一DU向该目标CU发送第一承载建立响应,该第一承载建立响应包括用于指示是否需要为该第一业务分配业务资源的信息。
在本申请实施例中,当该第一DU根据该第一标识确定了是否需要为该第一业务分配业务资源后,可以向目标CU返回第一承载建立响应,该第一承载建立响应携带由于指示是否需要为该第一业务分配业务资源的信息,则以此实现了目标CU和该第一DU的通信连接。
510、该目标CU向该源CU发送CU切换响应,该CU切换响应包括用于指示是否需要为该第一业务分配业务资源的信息。
在本申请实施例中,当目标CU与该第一DU实现了通信连接后,可以向源CU发送CU切换响应,以指示该源CU断开与该第一DU的连接,以实现UE从源CU到目标CU的切换。另外,该CU切换响应携带是否需要为该第一业务分配业务资源的信息,则确定该第一DU是否正在使用第一业务资源服务该目标UE,若是,则不需要另外为该UE重新分配业务资源,则此次CU切换的过程中,只需要占用一份业务资源,而不需要占用两份业务资源,从而节省了CU的切换过程中的无线资源的开销,由于在切换的过程中不需要中断第一DU和UE的连接,因此UE无感知,数据无中断,从而增进了用户体验。
