Description

一种通信方法和设备 技术领域
本发明涉及通信领域,具体涉及一种通信方法和设备。
背景技术
下一代移动网络中,存在多个应用系统分别为用户设备(UE,User Equipment)提供服务,每个应用系统包含对应的应用网络和应用管理单元。
当UE位置发生变化时,如图1b所示,UE从一个应用系统(后面称为源应用系统)的应用网络1的服务区域进入另一个应用系统(后面称为目标应用系统)的应用网络2的服务区域,为了让用户随时随地获得良好的业务体验,UE执行跨系统切换,即从源应用系统切换到目标应用系统。在UE的切换过程中,目标应用管理单元获取UE的位置和应用信息,确定应用在目标应用系统中的目标位置信息;源应用管理单元获取目标应用管理单元为应用分配的目标位置信息,触发应用迁移;最后,应用在目标应用系统准备完成后,激活目标用户面的本地分流规则。
在现有技术中,由于源应用管理单元与目标应用管理单元属于不同的应用系统,两者不能直接通信,而是由第三方,如正在与迁移应用通信的客户端,使用API从源应用管理单元中获取UE的应用信息,再将UE的应用信息发送给目标应用管理单元,目标应用管理单元根据UE的应用信息和UE的位置,确定应用在目标应用系统中的运行位置后,将应用目标位置信息发送给第三方,由第三方向源应用管理单元发送应用目标位置信息,以完成UE的切换。
可见,在现有技术中,源应用管理单元与目标应用管理单元之间只能通过第三方来转发消息,首先移动通信系统也不支持这种通信方式,其次这种方式的通信效率较低,所以需要一种新的方式,让两个应用系统的应用管理单元能够相互寻址,直接通信。

具体实施方式
本发明实施例提供了一种通信方法和设备,用于UE的跨系统切换,可以使应用管理单元之间建立连接,相互通信,有效提高通信效率。
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,本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明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。
在3GPP标准中,下一代移动网络的用户面重选架构之一如图1a所示,包括用户设备(UE,User Equipment),接入网(AN,Access Network)设备,用户面(UP,User Plane)设备,控制面(CP,Control Plane)设备,以及应用控制器(AS controller,Application Server controller)和应用网络(AS network,Application Server network),其中,控制面设备负责移动网络的管理,用户面设备负责业务数据的传输,应用控制器属于应用管理单元的一种,图中以应用控制器进行示例说明,应用管理单元一般位于运营商可信任领域,负责应用网络中应用的管理,如应用的迁移,应用的实例化,应用的网络配置,应用的终结,资源的维护等,还可以与控制面交互,传递应用相关信息,如应用的位置,应用的状态,应用的迁移事件等,以辅助控制面在移动网络中选择最优的传输路径,应用管理单元也能够从控制面获取信息,优化应用管理,其中,应用管理单元包括应用控制器或边缘计算编排器。应用网络和应用管理单元组成一个本地应用系统,或者称之为边缘应用系统,其中应用管理单元是应用系统中唯一的一个管理实体。应用系统的运营商有多重角色,第一,可由服务提供商运 营,承包给个人,如每个区域,如村、乡、小区、公司、校园等位置由个人负责,多个服务提供商与网络运营商联合部署本地应用系统;第二,也可由虚拟运营商运营与本地服务提供商,网络运营商合作;第三,网络运营商也可以自己部署本地AS网络,提供本地应用。
需要说明的是,在一些应用系统中,由于安全等原因,同一应用系统的控制面设备与应用管理单元之间不能直接通信,而是通过能力开放平台完成控制面设备与应用管理单元之间的信息交互。
由于应用系统运营商可以是个人,虚拟运营商,服务运营商,网络运营商等诸多角色,而且其应用网络只能服务于有限的区域,所以存在下面两种场景:一个PLMN网络中存在多个应用系统提供业务;一个PLMN网络只部署一个应用系统提供业务。
在UE的跨系统切换中,如图1b所示,UE从一个应用系统(后面称为源应用系统)的应用网络1的服务区域进入另一个应用系统(后面称为目标应用系统)的应用网络2的服务区域,为了让用户随时随地获得良好的业务体验,UE执行跨系统切换,即从源应用系统切换到目标应用系统,在UE的切换过程中,目标应用管理单元要获取UE的位置和应用信息,决策应用在目标应用系统中的运行位置;其次,源应用管理单元要获取目标应用管理单元为应用预留的位置,触发应用迁移;最后,应用在目标应用系统准备完成后,激活目标用户面的本地分流规则。现有技术中,两个应用管理单元之间不能直接通信,只能通过第三方中转,通信效率较低。
本发明实施例就是为了解决UE跨系统切换的场景下,现有技术中两个应用管理单元之间不能直接通信的问题,在本发明实施例的网络环境中,存在源应用系统和目标应用系统,源应用系统包括源用户面设备、源控制面设备和源应用管理单元,目标应用系统包括目标用户面设备、目标控制面设备和目标应用管理单元,UE从源应用系统的服务区域进入到目标应用系统的服务区域,需要执行跨系统切换。
