Description

一种短消息发送方法及装置
本申请要求在2017年11月10日提交中华人民共和国知识产权局、申请号为201711105361.2、发明名称为“一种短消息发送方法及装置”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
本申请涉及移动通信技术领域,尤其涉及一种短消息发送方法及装置。
背景技术
短消息服务(short message service,SMS)是电信业务的一种。短消息是公共陆地移动网络(public land mobile network,PLMN)中通过信令通道传输的非实时的可靠的数据包。短消息服务通过存贮转发的方式,提供点到点、非实时、可靠的数据传输业务。
目前,短消息的发送方式为,当短消息中心接收到终端A发送的短消息时,短消息中心向统一数据管理(unified data management,UDM)网元请求获取一个短消息服务功能(SMS function,SMSF)网元的标识信息,然后短消息中心将短消息发送给该SMSF网元。进一步地,由该SMSF网元将短消息发送至终端B,完成短消息的发送。
在实际应用中,由于终端的移动等原因,导致终端漫游,终端可能会同时注册在多个PLMN,不同的PLMN下有不同的SMSF网元来发送短消息。进而,UDM网元上可能同时存储对应同一个终端的多个SMSF网元的标识信息。
在上述情形下,当短消息中心需要向终端发送短消息时,短消息中心向UDM网元请求获取SMSF网元的标识信息时,UDM网元向短消息中心返回哪一个SMSF网元的标识信息,目前还没有给出相应的解决方案。
发明内容
本申请提供一种短消息发送方法及装置,用以实现短消息服务网元的标识信息的选择和提升通信质量。
第一方面,本申请提供一种短消息发送方法,该方法可由数据管理网元或数据管理网元内的芯片执行。该方法包括:数据管理网元接收来自短消息中心的请求消息,请求消息用于请求短消息服务网元的标识信息,短消息服务网元用于将来自短消息中心的短消息发送至终端。接着,数据管理网元根据终端的偏好信息,从数据管理网元存储的至少两个短消息服务网元的标识信息中选择一个短消息服务网元的标识信息,偏好信息用于指示终端偏好的接入技术,终端偏好的接入技术与选择的短消息服务网元的标识信息关联。最后,数据管理网元将选择的短消息服务网元的标识信息发送到短消息中心。
上述方法,在数据管理网元同时存储多个短消息服务网元的标识信息与接入技术的关联关系,同时还存储终端的偏好信息。当数据管理网元需要选择短消息服务网元的标识信息时,可以根据终端的偏好信息,选择一个短消息服务网元的标识信息,实现了从多个短消息服务网元的标识信息中选择一个短消息服务网元的标识信息。并且, 由于是基于终端的偏好信息进行选择的,因而有助于提升通信质量。
在一种可能的实现方式中,数据管理网元存储的至少两个短消息服务网元的标识信息包括第一短消息服务网元的标识信息和第二短消息服务网元的标识信息。数据管理网元从第一接入与移动性管理网元接收第一公共陆地移动网络PLMN的第一接入技术的信息,以及,从第一短消息服务网元接收第一短消息服务网元的标识信息。数据管理网元建立第一短消息服务网元的标识信息与第一接入技术的关联。数据管理网元从第二接入与移动性管理网元接收偏好信息和第二PLMN的第二接入技术的信息,以及,从第二短消息服务网元接收第二短消息服务网元的标识信息,偏好信息为短消息业务对应的第一接入技术或第二接入技术。数据管理网元建立第二短消息服务网元的标识信息与第二接入技术的关联关系。其中,第一接入与移动性管理网元和第一短消息服务网元位于第一PLMN,第二接入与移动性管理网元和第二短消息服务网元位于第二PLMN。
通过上述方法,实现了在数据管理网元中存储第一短消息服务网元的标识信息和第一接入技术的关联,存储第二短消息服务网元的标识信息和第二接入技术的关联,以及存储终端的偏好信息。
在一种可能的实现方式中,数据管理网元在选择短消息服务网元的标识信息之前,还需要确定终端在第一接入技术下处于空闲态,且确定终端在第二接入技术下处于空闲态。或者,数据管理网元确定终端在第一接入技术下处于连接态,且确定终端在第二接入技术下处于连接态。
通过上述方法,首先判断终端在第一接入技术下的状态和第二接入技术下的状态。若终端在第一接入技术下的状态为连接态,在第二接入技术下的状态为空闲态,则选择第一接入技术对应的第一短消息服务网元的标识信息。若终端在第一接入技术下的状态为空闲态,在第二接入技术下的状态为连接态,则选择第二接入技术对应的第短消息服务网元的标识信息。若终端在第一接入技术下处于空闲态且终端在第二接入技术下处于空闲态,或者终端在第一接入技术下处于连接态且终端在第二接入技术下处于连接态,则数据管理网元依据前述方法,依据偏好信息选择短消息服务网元的标识信息。从而有助于提升选择短消息服务网元的标识信息的效率。
第二方面,本申请提供一种短消息发送方法,该方法可由数据管理网元或数据管理网元内的芯片执行。该方法包括:数据管理网元获取第一短消息服务网元的标识信息与第一接入技术的关联。在数据管理网元将第一短消息服务网元的标识信息删除后,数据管理网元通知接入与移动性管理网元:选择第二短消息服务网元并触发第二短消息服务网元激活通过第二接入技术实现的短消息业务。其中,第一短消息服务网元和第二短消息服务网元分别位于第一PLMN和第二PLMN,第一接入技术和第二接入技术分别对应第一PLMN和第二PLMN。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请作进一步地详细描述。方法实施例中的具体操作方法也可以应用于装置实施例或系统实施例中。其中,在本申请的描述中,除非另有说明,“多个”的含义是两个或两个以上。
如图1所示,本申请适用的一种可能的网络架构示意图。该网络架构为短消息服务SMS的双注册场景。
当终端已经通过第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)接入技术(称为第一接入技术)接入到一个PLMN(称为第一PLMN),并成功注册到了位于该第一PLMN的接入与移动性管理功能(Access and Mobility Management Function,AMF)网元(称为第一AMF),则归属域PLMN的UDM网元会存储第一 PLMN的第一AMF的标识信息,以及存储第一AMF对应的第一接入技术。
如果终端同时在另一个PLMN(称为第二PLMN)内发现非3GPP接入技术(称为第二接入技术),并通过该第二接入技术接入到第二PLMN,则终端会向位于该第二PLMN的AMF网元(称为第二AMF)发起注册请求。进而,归属域PLMN的UDM会存储第二PLMN的第二AMF的标识信息,以及存储第二AMF对应的第二接入技术。
此时,终端同时注册到第一AMF和第二AMF,即同时存在两个不同的PLMN的不同的AMF为终端提供服务,UDM也同时维护两个不同PLMN的不同AMF网元的标识信息。该场景称为双注册。
根据上述描述,当PLMN不同且接入类型不同时,即UDM网元判断终端通过不同运营商,分别通过不同接入技术接入到网络时,UDM网元允许双注册。在双注册场景下,终端既可以在3GPP接入下实现短消息业务,也可以在非3GPP接入下实现短消息业务。
根据图1所示的架构,当终端同时通过3GPP接入和非3GPP接入附着在两个不同的PLMN的不同AMF网元时,由于SMSF网元无法跨运营商,因此,不同PLMN的不同AMF网元需要分别在所在的PLMN内选择一个本地的SMSF网元。参考图1,第一AMF在第一PLMN内选择的SMSF网元称为第一SMSF,第二AMF在第二PLMN内选择的SMSF网元称为第二SMSF。
SMSF网元主要用于短消息的路由转发。具体地,在下行方向,SMSF网元接收来自短消息中心的短消息,并将该短消息路由转发至相应的终端。在上行方向,SMSF网元接收来自终端的短消息,然后将该短消息路由转发至短消息中心。
如图1所示,作为示例,第二PLMN为终端的归属PLMN,则UDM网元位于该第二PLMN。在UDM网元内,存储有第一AMF的标识信息、第一SMSF的标识信息、第一接入技术之间的关联关系,以及,还存储有第二AMF的标识信息、第二SMSF的标识信息、第二接入技术之间的关联关系。
基于上述场景,在下行方向,当短消息中心需要向终端发送短消息时,短消息中心向UDM网元请求获取一个SMSF网元的标识信息,如SMSF网元的标识信息可以是地址信息或标识等。但由于UDM网元存储了不止一个SMSF网元的标识信息,此时,UDM网元向短消息中心返回哪一个SMSF网元的标识信息,则需要给出明确的定义。
为解决上述问题,本申请将提供多种解决方案,后续会分别说明。
在介绍本申请的发明方案之前,再对图1所示的系统架构做进一步的补充说明。
本申请中的终端,是一种具有无线收发功能的设备,可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端、增强现实(augmented reality,AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
AMF网元,具有移动性管理功能,负责用户的移动性管理,包括移动状态管理, 分配用户临时身份标识,认证和授权用户等。
UDM网元,具有用户数据管理功能,负责存储用户的签约数据,包括移动管理相关的签约数据以及会话管理相关的签约数据。以及接收SMSF网元的短消息注册请求消息,并将注册的SMSF网元的标识信息返回给短消息中心。
本申请中的短消息中心,可实现短消息的接收、存储、转发和短消息状态报告等功能,短消息中心还应包括操作维护模块和与网络间传递消息、选择发送路由的网关模块。
需要说明的是,上述描述中,将3GPP接入技术称为第一接入技术,非3GPP接入技术称为第二接入技术。当然,也可以将3GPP接入技术称为第二接入技术,非3GPP接入技术称为第一接入技术。
上述描述中,以第二PLMN为归属PLMN,UDM位于第二PLMN为例,当然,也可以是第一PLMN为归属PLMN,UDM位于第一PLMN。
实际应用中,终端既可以是先通过3GPP接入技术注册至第一PLMN,后通过非3GPP接入技术注册至第二PLMN。也可以是先通过非3GPP接入技术注册至第二PLMN,后通过3GPP接入技术注册至第一PLMN。
本申请中,涉及到的网元主要有数据管理网元、短消息服务网元、接入与移动性管理网元。其中,数据管理网元主要负责数据的管理功能,例如,数据管理网元可以是UDM网元等。短消息服务网元主要负责短消息的传输功能,例如,短消息服务网元可以是SMSF网元等。接入与移动性管理网元主要负责用户的移动性管理,例如,接入与移动性管理网元为AMF网元等。
为方便说明,本申请以数据管理网元为UDM网元,短消息服务网元为SMSF网元,接入与移动性管理网元为AMF网元为例,对本申请的方案进行说明。进一步地,为方便说明,后续将UDM网元、SMSF网元、AMF网元分别简称为UDM、SMSF、AMF。
如图2所示,为本申请所适用的短消息注册流程示意图。图1所示的系统架构中,终端在第一PLMN的短消息注册流程和终端在第二PLMN的短消息注册流程,均可以分别按照如下方法步骤进行注册。该注册流程包括以下步骤:
步骤1,终端向AMF发送注册请求消息。
其中,注册请求消息中携带指示信息,指示信息用于指示终端具备短消息能力。
指示信息还可以用于指示终端支持短消息传输的接入技术。例如,指示信息指示终端支持3GPP接入技术,或者指示信息指示终端支持非3GPP接入技术,或者指示信息指示终端支持3GPP接入技术和非3GPP接入技术。
步骤2,AMF向UDM发起更新位置(Update Location)流程。
如果终端发送的注册请求消息中包含了指示信息,则AMF在该流程中,向UDM进行签约检查,以确认该终端是否允许进行短消息业务。如果签约允许,则AMF为终端选择一个SMSF。
其中,AMF选择SMSF的机制可以是下列任一种方式:
方式1,SMSF的标识信息预先配置在AMF上。
方式2,AMF在Update Location流程中从UDM获取SMSF的标识信息。
方式3,AMF向网络发现功能(Network Repository Function,NRF)网元请求 发现SMSF的标识信息。
步骤3,AMF向终端发送注册接受消息。
AMF为终端选择了SMSF网元之后,AMF向终端发送注册接受消息,该注册接受消息中可以包括指示信息,该指示信息用于指示网络是否允许终端在3GPP接入技术下使用短消息业务,或者用于指示网络是否允许终端在非3GPP接入技术下使用短消息业务,或者用于指示网络是否允许终端在3GPP接入技术和非3GPP接入技术下使用短消息业务。
步骤4,AMF向SMSF发送激活请求消息。
该激活请求消息携带AMF的标识信息,终端的标识信息,以触发SMSF激活终端的短消息业务。例如,AMF的标识信息可以是标识或地址信息。
步骤5a,SMSF向UDM获取终端的短消息相关的签约数据。
SMSF获取的终端的短消息相关的签约数据,包括短消息相关的签约数据,例如计费规则、是否允许漫游,支持的接入技术等。
SMSF根据获取的终端的短消息相关的签约数据,创建终端的上下文,该上下文包括上述签约数据,还包括AMF的标识信息,终端的标识信息。
步骤5b,SMSF向UMD注册。
例如,SMSF向UMD发送SMSF的标识信息,AMF的地址信息,终端的标识信息,对应的接入技术,以实现注册,从而UDM存储了SMSF的标识信息,AMF的地址信息,终端的标识信息,对应的接入技术等信息。
步骤6,SMSF向AMF发送激活响应消息。
该激活响应消息用于指示短消息业务是否成功激活。如果成功,则AMF将SMSF的标识信息存储在终端的上下文中。
在另一种实现方式中,上述步骤3还可以是在上述步骤6之后执行。
图2所示的上述流程,即为本申请中终端注册并激活短消息业务的流程。
下面具体介绍本申请为解决背景技术中的问题而提出的各种解决方案。
解决方案一
如图3所示,为本申请提供的第一种解决方案对应的示意图。终端首先向第一AMF发送注册请求消息,请求注册至第一PLMN的第一AMF,第一AMF向UDM发送第一接入技术的信息,然后第一AMF选择第一SMSF并指示第一SMSF激活通过第一接入技术实现的短消息业务。在第一SMSF激活通过第一接入技术实现的短消息业务的过程中,第一SMSF将第一SMSF的标识信息发送至UDM。从而UDM获取了第一SMSF的标识信息、第一接入技术的信息,进而建立第一SMSF的标识信息与第一接入技术的关联。
进一步地,终端后续可以继续发起注册请求。例如,当终端漫游时,终端可以请求注册至第二PLMN的第二AMF。然后第二AMF向UDM发送第二接入技术的信息,第二AMF选择第二SMSF并指示第二SMSF激活通过第二接入技术实现的短消息业务。在第二SMSF激活通过第二接入技术实现的短消息业务的过程中,第二SMSF将第二SMSF的标识信息发送至UDM。从而UDM获取了第二SMSF的标识信息、第二接入技术的信息,进而建立第二SMSF的标识信息与第二接入技术的关联。
其中,第一接入技术为3GPP接入技术,第二接入技术为非3GPP接入技术,或者,第一接入技术为非3GPP接入技术,第二接入技术为3GPP接入技术。
因此,当双注册成功时,则UDM上存储的终端的上下文包括第一SMSF的标识信息与第一接入技术的关联,第二SMSF的标识信息与第二接入技术的关联。
进一步地,UDM在终端的上下文中还存储该终端的偏好信息,偏好信息用于指示终端偏好的接入技术。例如,偏好信息指示终端偏好第一接入技术,或者,指示终端偏好第二接入技术。
其中,UDM中存储的终端的偏好信息,可以是终端签约入网时,直接存储在UDM中的。或者,还可以是终端在上述请求注册至第二PLMN时,由终端发送至第二AMF,并由第二AMF发送至UDM的。例如,参考图3,终端在发起注册请求时,将终端的偏好信息携带于注册请求消息中发送至第二AMF,然后由第二AMF发送至UDM。
如表1所示,为通过表格形式展示的UDM存储的终端的上下文。
Figure PCTCN2018100849-appb-000001
表1 UDM存储的终端的上下文
当然,UDM存储的终端的上下文还包括其它信息,本申请不做具体限定。例如,终端的上下文中,可以存储第一PLMN、第一AMF与第一SMSF的标识信息、第一接入技术之间的关联关系,以及存储第二PLMN、第二AMF与第二SMSF的标识信息、第二接入技术之间的关联关系。
基于UDM存储的上述信息,本申请提供一种短消息的发送方法,如图5所示,包括以下步骤:
步骤501,短消息中心向UDM发送请求消息,UDM接收来自短消息中心的请求消息。
当短消息中心有下行数据,即有短消息需要发送至终端时,短消息中心向UDM发送请求消息,该请求消息用于请求SMSF的标识信息。
步骤502,UDM根据终端的偏好信息,从UDM存储的至少两个SMSF的标识信息中选择一个SMSF的标识信息。
例如,UDM中存储了两个SMSF的标识信息,如表1所示,分别为第一SMSF的标识信息和第二SMSF的标识信息。并且,第一SMSF的标识信息对应第一接入技术,第二SMSF的标识信息对应第二接入技术。进一步地,UDM还存储了终端的偏好信息。
如果该偏好信息指示了终端偏好的接入技术为第一接入技术,则该步骤502中,UDM选择的是第一SMSF的标识信息。如果该偏好信息指示了终端偏好的接入技术为 第二接入技术,则该步骤502中,UDM选择的是第二SMSF的标识信息。即偏好信息指示的终端偏好的接入技术与选择的SMSF的标识信息关联。
步骤503,UDM向短消息中心发送选择的SMSF的标识信息,短消息中心接收来自UDM的选择的SMSF的标识信息。
从而,短消息中心可向选择的SMSF发送短消息。该选择的SMSF在接收到短消息后,将该短消息发送至终端。
通过上述步骤501-步骤503,一方面,实现了从多个SMSF的标识信息中选择一个发送给短消息中心,另一方面,由于是基于终端偏好的接入技术选择SMSF,有利于提升通信质量。
作为另一种实现方法,还可以在上述步骤501-步骤503中引入终端的状态,作为选择SMSF的另一个参考依据。
例如,作为一种可替代的实现方案,上述步骤502可由下述步骤502A-步骤502C替换。
步骤502A,UDM向第一AMF查询终端在第一接入技术下的状态,以及向第二AMF查询终端在第二接入技术下的状态。
步骤502B,UDM若确定终端在第一接入技术下处于空闲态,且终端在第二接入技术下处于连接态,则选择第二SMSF的标识信息。UDM若确定终端在第一接入技术下处于连接态,且终端在第二接入技术下处于空闲态,则选择第一SMSF的标识信息。
流程结束。
步骤502C,UDM若确定终端在第一接入技术和第二接入技术下均处于空闲态,或者确定终端在第一接入技术和第二接入技术下均处于连接态,则UDM根据终端的偏好信息,从UDM存储的至少两个SMSF的标识信息中选择一个SMSF的标识信息。
其中,UDM根据终端的偏好信息,从UDM存储的至少两个SMSF的标识信息中选择一个SMSF的标识信息的具体实现方式,可参考前述步骤502的相关描述,这里不再赘述。
流程结束。
综上,若上述步骤502由步骤502A-步骤502C替换,则UDM先是根据终端分别在第一接入技术和第二接入技术的状态来选择SMSF的标识信息,若根据终端的状态不能选择出SMSF,则进一步地根据终端的偏好信息选择SMSF的标识信息。
综上,本申请的第一种解决方案,是在UDM同时存储每个SMSF的标识信息与接入技术的关联关系,同时还存储终端的偏好信息。从而,当UDM需要选择SMSF时,可以根据终端的偏好信息,选择一个SMSF,实现了从多个SMSF的标识信息中选择一个,并且,由于是基于终端的偏好信息进行选择的,因而有助于提升通信质量。
解决方案二
如图4所示,为本申请提供的第二种解决方案对应的示意图。终端首先向第一AMF发送注册请求消息,请求注册至第一PLMN的第一AMF,第一AMF向UDM发送第一接入技术的信息,然后第一AMF选择第一SMSF并指示第一SMSF激活通过第一接入技术实现的短消息业务。在第一SMSF激活通过第一接入技术实现的短消息业务的过程中,第一SMSF将第一SMSF的标识信息发送至UDM。从而UDM获取了第一 SMSF的标识信息、第一接入技术的信息,进而UDM建立第一SMSF的标识信息与第一接入技术的关联。
进一步地,当终端后续发起注册请求,请求注册至第二PLMN的第二AMF时,网络侧允许终端注册至第二PLMN的第二AMF。但是,网络侧只有在确定终端的偏好信息指示的是第二接入技术,或者确定第二PLMN的偏好信息指示的是第二接入技术时,才允许终端激活通过第二接入技术实现的短消息业务。
如果终端的偏好信息指示的是第一接入技术,或者第一PLMN的偏好信息指示的是第一接入技术,则网络侧不允许终端激活通过第二接入技术实现的短消息业务。进一步地,只有当终端在第一PLMN去注册,或者在第一PLMN去激活通过第一接入技术实现的短消息业务时,网络侧才允许终端激活通过第二接入技术实现的短消息业务。
当然,也可以是终端自己决定是否激活通过第二接入技术实现的短消息业务。
综上,在该第二种解决方案中,在终端已经注册至第一PLMN,且激活了通过第一接入技术实现的短消息业务的前提下,如果终端还想注册至第二PLMN且想要激活通过第二接入技术实现的短消息业务,则允许终端注册至第二PLMN,但是否允许终端激活通过第二接入技术实现的短消息业务,则取决于终端的偏好信息,或者取决于第二PLMN的偏好信息。
比如,若终端或第二PLMN的偏好信息指示偏好第二接入技术,则允许终端激活通过第二接入技术实现的短消息业务。
再比如,若终端或第二PLMN的偏好信息指示偏好第一接入技术,则不允许终端激活通过第二接入技术实现的短消息业务。进一步地,如果终端在第一PLMN去注册,或者在第一PLMN去激活通过第一接入技术实现的短消息业务,则允许终端激活通过第二接入技术实现的短消息业务。
因此,在该第二种解决方案中,UDM中存储的可能只有一个SMSF的标识信息与接入技术之前的关联关系。如表2所示,为通过表格形式展示的UDM存储的终端的上下文的一种可能结果。
Figure PCTCN2018100849-appb-000002
表2 UDM存储的终端的上下文
如表3所示,为通过表格形式展示的UDM存储的终端的上下文的另一种可能结果。
Figure PCTCN2018100849-appb-000003
表3 UDM存储的终端的上下文
当然,也有可能UDM存储的终端的上下文中存储了两个SMSF的标识信息与接入技术之前的关联关系,如表1所示。
在该第二种解决方案中,如果UDM存储的终端的上下文是如表2或表3所示,则UDM在接收到短消息中心的请求消息时,UDM直接获取当前存储的SMSF的标识信息发送给短消息中心,而无需选择,可提升通信效率。
当然,如果在该第二种解决方案中,如果UDM存储的终端的上下文是如表1所示,则UDM在接收到短消息中心的请求消息时,可以参考前述第一种解决方案中的步骤502或者参考步骤502A-步骤502C的方案,来选择一个SMSF。
在该第二种解决方案中,由于偏好信息存储的位置的不同,相应的,可以有多种具体的实现方法。下面分别说明。
首先,终端通过图2所示的注册方法,注册至第一PLMN的第一AMF,且激活了通过第一接入技术实现的短消息业务,并且第一AMF选择了第一SMSF。
此时,UDM终端存储的终端的上下文如上述表2所示。
接着,当终端想要注册至第二PLMN的第二AMF且想要激活通过第二接入技术实现的短消息业务时,则可以允许终端注册至第二PLMN,至于是否允许终端激活通过第二接入技术实现的短消息业务,则根据偏好信息存储的位置的不同,有多种实现方法。下面分别介绍。
其中,偏好信息为终端的偏好信息或第二PLMN的偏好信息。
例如,若偏好信息是终端的偏好信息,则该偏好信息用于指示终端偏好的接入技术,可以是第一接入技术,也可以是第二接入技术。
再比如,若偏好信息是第二PLMN的偏好信息,则该偏好信息用于指示第二PLMN偏好的接入技术,可以是第一接入技术,也可以是第二接入技术。
情形一、终端存储有偏好信息
该情形下,由于终端存储有偏好信息,则终端可以决策是否激活通过第二接入实现的短消息业务,或者,终端将偏好信息发送至第二AMF,由第二AMF决策是否激活通过第二接入实现的短消息业务。下面分别说明。
实现方法一、终端决策是否激活通过第二接入实现的短消息业务
该实现方法一中,终端存储有偏好信息,且由终端决策是否激活通过第二接入实现的短消息业务。如图6所示,为实现方法一对应的短消息发送方法,具体包括以下步骤:
步骤601,终端根据偏好信息,判断是否触发通过第二接入技术实现的短消息业务的激活。
若偏好信息指示偏好的接入技术是第一接入技术,则终端决定只注册至第二PLMN的第二AMF,但不触发通过第二接入技术实现的短消息业务的激活,即执行步骤602-609。
若偏好信息指示偏好的接入技术是第二接入技术,则终端决定不但注册至第二PLMN的第二AMF,而且触发通过第二接入技术实现的短消息业务的激活,即执行步骤610-611。
步骤602,终端通过第二PLMN的第二接入技术,向第二AMF发送注册请求消 息。
该注册请求消息用于指示不触发通过第二接入技术实现的短消息业务的激活。
在一种实现方式中,可以是在该注册请求消息中携带指示信息,该指示信息用于指示不触发通过第二接入技术实现的短消息业务的激活。当第二AMF获取到指示信息时,可确定不触发通过第二接入技术实现的短消息业务的激活。
在另一种实现方式中,可以是在该注册请求消息中不携带用于指示终端支持短消息业务的指示信息。当第二AMF接收到注册请求消息时,由于没有获取到指示信息,则确定不触发通过第二接入技术实现的短消息业务的激活。
该步骤602中,终端仍然可以注册至第二PLMN的第二AMF,只是不激活通过第二接入技术实现的短消息业务。
需要说明的是,若终端注册至第一PLMN的第一AMF时,向第一AMF发送的注册请求消息称为第一注册请求消息,则该步骤602中的注册请求消息可以称为第二注册请求消息。
步骤603,第二AMF向终端发送第一指示信息,第一指示信息用于指示通过第二接入技术实现的短消息业务未激活。
即,在第二AMF确定不触发终端通过第二接入技术实现的短消息业务的激活后,第二AMF向终端发送第一指示信息,第一指示信息用于指示通过第二接入技术实现的短消息业务未被激活。作为一种实现方式,该第一指示信息可以是携带于第二AMF发送给终端的注册接受消息中的。
上述实现方式可以称为显示指示方式,即第二AMF显示地通知终端:通过第二接入技术实现的短消息业务未被激活。
作为另一种实现方式,第二AMF还可以通过隐式指示方式通知终端:通过第二接入技术实现的短消息业务未被激活。比如,作为该步骤603的一种可替代方案,可以是第二AMF向终端发送注册接受消息,该注册接受消息中不携带用于指示通过第二接入技术实现的短消息业务被激活的指示信息,则当终端接收到该注册接受消息时,可以判断得知通过第二接入技术实现的短消息业务未被激活。
步骤604,第二AMF向UDM订阅:当UDM将第一SMSF的标识信息删除后,UDM通知第二AMF。
第二AMF向UDM获取签约数据时,如果该终端的签约数据允许终端使用短消息业务,但是终端在步骤602中,却不激活通过第二接入技术实现的短消息业务,那么第二AMF需要向UDM订阅:当UDM将第一SMSF的标识信息删除后,UDM通知第二AMF。
例如,当终端从第一PLMN去注册时,UDM会将上述表2中存储的信息都删除,例如删除第一SMSF的标识信息,第一接入技术等。
再比如,当终端在第一PLMN的通过第一接入技术实现的短消息业务去激活时,UDM会将上述表2中存储的第一SMSF的标识信息删除,但可以保留其它信息。
不管采用何种方式,只要UDM将第一SMSF的标识信息删除后,则UDM通知第二AMF。
步骤605,UDM获取第一SMSF的标识信息与第一接入技术的关联,当UDM将第一SMSF的标识信息删除后,通知第二AMF:选择第二SMSF并触发第二SMSF激 活通过第二接入技术实现的短消息业务。
该步骤605为可选步骤,只有当UDM需要删除第一SMSF的标识信息时才执行。具体地,可以是终端从第一PLMN的去注册,或终端在第一PLMN的通过第一接入技术实现的短消息业务的去激活时,UDM删除第一SMSF的标识信息。
UDM在删除了第一SMSF的标识信息后,根据第二AMF之前的订阅,UDM通知第二AMF去选择第二SMSF,并触发该第二SMSF激活通过第二接入技术实现的短消息业务。
需要说明的是,UDM通知第二AMF的方式,可以是通过通知消息的方法,也可以是通过服务调用的方式,本申请不做限定。
步骤606,第二AMF选择第二SMSF,以及触发第二SMSF激活通过第二接入技术实现的短消息业务。
步骤607,第二SMSF向UDM查询终端的签约数据,判断是否允许激活通过第二接入技术实现的短消息业务,若签约允许,则第二SMSF向UMD注册。
该步骤607的具体实现过程,可参考上述图2所示的短消息注册流程中的步骤5a和步骤5b的相关描述,这里不再赘述。
步骤608,第二SMSF向第二AMF发送激活响应消息。
该激活响应消息用于通知第二AMF:终端通过第二接入技术实现的短消息业务已激活。
步骤609,第二AMF向终端发送第二指示信息,第二指示信息用于指示通过所述第二接入技术实现的短消息业务已被激活。
即,在第二AMF获知通过第二接入技术实现的短消息业务已激活后,第二AMF向终端发送第二指示信息,第二指示信息用于指示通过第二接入技术实现的短消息业务已被激活。
流程结束。
步骤610,终端发起将通过第一接入技术实现的短消息业务去激活的流程。
该步骤610中,终端发起将通过第一接入技术实现的短消息业务去激活的流程,从而实现将终端通过第一接入技术实现的短消息业务去激活。接着执行步骤611。
步骤611,终端通过第二PLMN的第二接入技术,向第二AMF发送注册请求消息。
该步骤611的注册请求消息中包括用于指示终端支持通过第二接入技术实现的短消息业务的指示信息。
该步骤611后续的注册流程,可参考图2所示的注册流程,这里不再赘述。
其中,需要说明的是,网络侧在完成了终端通过第二接入技术实现的短消息业务的激活之后,第二AMF还向终端发送第二指示信息,该第二指示信息用于指示通过第二接入技术实现的短消息业务已激活。
在完成了步骤610-步骤611及步骤611的后续激活流程后,则UDM中存储的终端的上下文如上述表3所示。
综上,在该实现方法一中,终端在已经注册至第一PLMN的第一AMF,且激活了通过第一接入技术的前提下,若终端想要注册且第二PLMN的第二AMF,且想要激活通过第二接入接入技术实现的短消息业务时,则终端根据存储的偏好信息判断是 否触发通过第二接入技术实现的短消息业务的激活。
一方面,终端若确定偏好信息指示偏好第一接入技术,则确定不触发通过第二接入技术实现的短消息业务的激活,则执行步骤602-步骤604,终端完成注册至第二PLMN的第二AMF,但不激活通过第二接入接入技术实现的短消息业务。并且,第二AMF在步骤603中通知终端通过第二接入技术实现的短消息业务的未激活,在步骤604中向UDM订阅:当UDM将第一SMSF的标识信息删除后,UDM通知第二AMF。需要说明的是,步骤603和步骤604的顺序可以互换,即也可以是先执行步骤604,再执行步骤603。后续,如果UDM确定删除了第一SMSF的标识信息,则通过步骤605通知第二AMF,进而通过步骤606-步骤609,完成终端通过第二接入技术实现的短消息业务的激活并通知终端。
另一方面,终端若确定偏好信息指示偏好第二接入技术,则确定触发通过第二接入技术实现的短消息业务的激活,则先通过步骤610,完成终端通过第一接入技术实现的短消息业务的去激活,然后通过步骤611及步骤611的后续步骤,完成终端注册至第二PLMN的第二AMF,以及完成通过第二接入技术实现的短消息业务的激活。
因此,该实现方法一,终端可基于偏好信息,自己选择是否激活通过第二接入技术实现的短消息业务。且UDM只存储一个SMSF的标识信息与接入技术的关联,因而UDM无需选择,而是直接确定SMSF的标识信息。
实现方法二、第二AMF决策是否激活通过第二接入实现的短消息业务
该实现方法二中,终端存储有偏好信息,且由第二AMF决策是否激活通过第二接入实现的短消息业务。如图7所示,为实现方法二对应的短消息发送方法,具体包括以下步骤:
步骤701,终端通过第二PLMN的第二接入技术,向第二AMF发送注册请求消息。
该注册请求消息用于请求触发通过第二接入技术实现的短消息业务的激活。
该注册请求消息中携带偏好信息和第二接入技术的信息。
步骤702,第二AMF获取偏好信息,并根据偏好信息判断是否触发通过第二接入技术实现的短消息业务的激活。
若偏好信息指示的偏好接入技术是第一接入技术,则第二AMF决定只允许终端注册至第二PLMN的第二AMF,但不触发通过第二接入技术实现的短消息业务的激活,则执行步骤703-步骤709。
若偏好信息指示的偏好接入技术是第二接入技术,则第二AMF决定不但允许终端注册至第二PLMN的第二AMF,而且触发通过第二接入技术实现的短消息业务的激活,则执行步骤710。
步骤703-步骤709,与上述图6所示的流程中的步骤603-步骤609类似,可参考前述描述,这里不再赘述。
步骤710,第二AMF触发第二SMSF激活通过第二接入技术实现的短消息业务。
该步骤710以及后续的注册流程,可参考图2所示的注册流程,这里不再赘述。
其中,需要说明的是,网络侧在完成了终端通过第二接入技术实现的短消息业务的激活之后,第二AMF还向终端发送第二指示信息,该第二指示信息用于指示通过第二接入技术实现的短消息业务已激活。
在完成了步骤710及步骤710的后续激活流程后,则UDM中存储的终端的上下文如上述表1所示。即,当第二AMF在步骤702中决定触发通过第二接入技术实现的短消息业务的激活时,执行步骤710及后续的注册流程,完成终端第二接入技术实现的短消息业务的激活。从而,在UDM中将存储第一SMSF的标识信息与第一接入技术的关联,以及存储第二SMSF的标识信息与第二接入技术的关联。
进一步地,若通过该实现方法二,UDM中存储了不止一个SMSF的标识信息与接入技术的关联,则还可以将该实现方法二与上述第一种解决方案相结合,以实现短消息的发送。即UDM中也存储有偏好信息,当UDM需要选择SMSF的标识信息时,由UDM根据偏好信息从多个SMSF的标识信息中选择一个,并将选择的SMSF的标识信息发送给短消息中心。
综上,在该实现方法二中,终端在已经注册至第一PLMN的第一AMF,且激活了通过第一接入技术的前提下,若终端想要注册且第二PLMN的第二AMF,且想要激活通过第二接入接入技术实现的短消息业务时,则终端首先注册至第二PLMN的第二AMF。然后由第二AMF决策是否触发通过第二接入技术实现的短消息业务的激活。
一方面,第二AMF若确定偏好信息为第一接入技术,则确定不触发通过第二接入技术实现的短消息业务的激活,则执行步骤703-步骤704,使得终端注册至第二PLMN的第二AMF,但不激活通过第二接入接入技术实现的短消息业务。并且,第二AMF在步骤703中通知终端通过第二接入技术实现的短消息业务的未激活,在步骤704中向UDM订阅:当UDM将第一SMSF的标识信息删除后,UDM通知第二AMF。需要说明的是,步骤703和步骤704的顺序可以互换,即也可以是先执行步骤704,再执行步骤703。后续,如果UDM确定删除了第一SMSF的标识信息,则通过步骤705通知第二AMF,进而通过步骤706-步骤709,完成终端通过第二接入技术实现的短消息业务的激活并通知终端。
另一方面,第二AMF若确定偏好信息为第二接入技术,则确定触发通过第二接入技术实现的短消息业务的激活,则通过步骤710及步骤710的后续步骤,完成终端注册至第二PLMN的第二AMF,以及完成通过第二接入技术实现的短消息业务的激活。
因此,该实现方法二,第二AMF可基于偏好信息,选择是否激活通过第二接入技术实现的短消息业务。
情形二、第二AMF存储有偏好信息
该情形二中,第二AMF存储有偏好信息,该偏好信息可以是预配置在第二AMF。且由第二AMF决策是否激活通过第二接入实现的短消息业务。
该情形二对应的短消息的发送方法的流程与上述情形一的实现方法二类似,该情形二与上述情形一的实现方法二的主要区别在于:偏好信息不是终端通过注册请求消息发送给第二AMF的,而是预配置在第二AMF。因此,第二AMF可以直接从本地获取到偏好信息。其它流程可参考上述情形一的实现方法二的相关描述,这里不再赘述。
情形三、UDM存储有偏好信息
该情形三中,UDM存储有偏好信息,且由UDM决策是否激活通过第二接入实现的短消息业务。如图8所示,为情形三对应的短消息发送方法的流程,具体包括以下 步骤:
步骤801,终端通过第二PLMN的第二接入技术,向第二AMF发送注册请求消息。
该注册请求消息用于请求触发通过第二接入技术实现的短消息业务的激活。
注册请求消息包括第二接入技术的信息。
步骤802,第二AMF向UDM发送注册请求消息。
注册请求消息包括第二接入技术的信息。
步骤803,UDM获取偏好信息,并根据偏好信息判断是否触发通过第二接入技术实现的短消息业务的激活。
若偏好信息指示的偏好接入技术是第一接入技术,则UDM决定不触发通过第二接入技术实现的短消息业务的激活,则执行步骤804-810。
若偏好信息指示的偏好接入技术是第二接入技术,则UDM决定触发通过第二接入技术实现的短消息业务的激活,则执行步骤811。
步骤804,UDM通知第二AMF不触发通过第二接入技术实现的短消息业务的激活。
步骤805,第二AMF向终端发送第一指示信息,第一指示信息用于指示通过第二接入技术实现的短消息业务未激活。
即,在第二AMF确定不触发终端通过第二接入技术实现的短消息业务的激活后,第二AMF向终端发送第一指示信息,第一指示信息用于指示通过第二接入技术实现的短消息业务未被激活。
UDM可在的终端激活通过第一接入技术实现的短消息业务的过程中获取第一SMSF的标识信息与第一接入技术的关联。步骤806,当UDM将第一SMSF的标识信息删除后,通知第二AMF:选择第二SMSF并触发第二SMSF激活通过第二接入技术实现的短消息业务。
该步骤806为可选步骤,只有当UDM需要删除第一SMSF的标识信息时才执行。具体地,可以是终端从第一PLMN的去注册,或终端在第一PLMN的通过第一接入技术实现的短消息业务的去激活时,UDM删除第一SMSF的标识信息。
UDM在删除了第一SMSF的标识信息后,通知第二AMF选择第二SMSF,并触发该第二SMSF激活通过第二接入技术实现的短消息业务。
需要说明的是,UDM通知第二AMF的方式,可以是通过通知消息的方法,也可以是通过服务调用的方式,本申请不做限定。
步骤807,第二AMF选择第二SMSF,以及触发第二SMSF激活通过第二接入技术实现的短消息业务。
步骤808,第二SMSF向UDM查询终端的签约数据,判断是否允许激活通过第二接入技术实现的短消息业务,若签约允许,则第二SMSF向UMD注册。
该步骤808的具体实现过程,可参考上述图2所示的短消息注册流程中的步骤5a和步骤5b的相关描述,这里不再赘述。
步骤809,第二SMSF向第二AMF发送激活响应消息。
该激活响应消息用于通知第二AMF:终端通过第二接入技术实现的短消息业务已激活。
步骤810,第二AMF向终端发送第二指示信息,第二指示信息用于指示通过所述第二接入技术实现的短消息业务已被激活。
即,在第二AMF获知通过第二接入技术实现的短消息业务已激活后,第二AMF向终端发送第二指示信息,第二指示信息用于指示通过第二接入技术实现的短消息业务已被激活。
流程结束。
步骤811,UDM通知第二AMF触发通过第二接入技术实现的短消息业务的激活。
该步骤811及步骤811的后续步骤可参考图2所示的注册流程,或者参考上述步骤806-步骤810的描述,这里不再赘述。
在完成了步骤610-步骤611及步骤611的后续激活流程后,则UDM中存储的终端的上下文如上述表3所示。
综上,在该情形三中,终端在已经注册至第一PLMN的第一AMF,且激活了通过第一接入技术的前提下,若终端想要注册且第二PLMN的第二AMF,且想要激活通过第二接入接入技术实现的短消息业务时,则终端向第二AMF发送注册请求消息,先注册至第二AMF。然后由第二AMF向UDM发送注册请求消息。
一方面,UDM若确定偏好信息指示偏好第一接入技术,则确定不触发通过第二接入技术实现的短消息业务的激活,则执行步骤804-步骤805,不激活通过第二接入接入技术实现的短消息业务。并且,第二AMF在步骤805中通知终端通过第二接入技术实现的短消息业务的未激活。后续,如果UDM确定删除了第一SMSF的标识信息,则通过步骤806通知第二AMF,进而通过步骤807-步骤810,完成终端通过第二接入技术实现的短消息业务的激活并通知终端。
另一方面,UDM若确定偏好信息指示偏好第二接入技术,则确定触发通过第二接入技术实现的短消息业务的激活,则通过步骤811及步骤811的后续步骤,完成通过第二接入技术实现的短消息业务的激活。
因此,该情形三,UDM可基于偏好信息,选择是否激活通过第二接入技术实现的短消息业务。
