步骤102,第一网元接收第二网元返回的第一服务发现响应,所述第一服务发现响应至少包括第三网元相关信息或第三网元集合相关信息。
在本公开实施例中,第一网元向第二网元发送所需DC媒体信息和/或本次呼叫请求的相关信息,第二网元基于第一网元所需DC媒体信息和/或本次呼叫请求的相关信息,查找符合这些信息的第三网元相关信息或第三网元集合相关信息,并返回给第一网元,以便第一网元基于第三网元相关信息或第三网元集合相关信息建立数据通道;如此,由于使得第一网元得到更为合适的第三网元,即第三网元是符合所需DC媒体信息和/或本次呼叫请求的相关信息的,因此可以提高数据通道建立的成功率,从而缩短通信时延。
在一些实施例中,第一服务发现请求为以下之一:DC媒体能力发现请求、DC媒体发现请求、DC媒体服务能力发现请求、DC媒体服务发现请求、DC服务能力发现请求、DC服务发现请求、DC网络功能发现请求(Nnrf_NFDiscovery_Request);本实施例中对第一服务发现请求的名称不做限定,上述名称在未进行特殊说明之外,均可同等或替换。
在一些实施例中,所述所需DC媒体信息包括以下信息中的至少之一:DC媒体能力(DC Media Capability)、DC媒体(DC Media)、DC媒体服务能力(DC Media Service Capability)、DC媒体服务(DC Media Service)、DC服务能力(DC Service Capability)、DC服务(DC Service)、DC网络功能(DC Network Function)、DC能力(DC Capability)、接口能力(Interface Capability)、DC媒体能力列表(DC Media Capability List)、DC媒体列表(DC Media List)、DC媒体服务能力列表(DC Media Service Capability List)、DC媒体服务列表(DC Media Service List)、DC服务能力列表(DC Media Service Capability List)、DC服务列表(DC Service List)、DC网络功能列表(DC Network Function List)、DC能力列表(DC Capability List)、接口能力列表(Interface Capability List)。本实施例中,对所需DC媒体信息的内容不做限定,对于所需DC媒

在一些实施例中,所述第一服务发现响应携带第三网元相关信息或第三网元集合相关信息。
可选地,在第一服务发现响应中包括一个第三网元的相关信息的情况下,第一网元直接将该第三网元作为目标网元,与其建立连接。
可选地,在第一服务发现响应中包括多个第三网元的相关信息(即第三网元集合相关信息)的情况下,第一网元可以基于以下信息的至少之一:所述第三网元集合相关信息、DC媒体需求信息、接口需求信息、本次呼叫请求的相关信息、第一终端的位置信息、第一终端的IP地址信息、已选择的媒体功能的信息,进行第三网元选择。“进行第三网元选择”也可以称为“确定第三网元”,即“进行第三网元选择”和“确定第三网元”是可等同的,均是为了选出符合上述信息的第三网元。
在本实施例中,实现对第三网元的发现和选择,基于第一终端的位置信息和/或DC媒体能力信息(即所需DC媒体信息)等,实现对第三网元的优化选择,以获得符合实际需求的第三网元,从而提高数据通道或媒体协商的成功率,进而缩短通信时延。换句话说,使网络可以按需高效实现对第三网元的调用,提高数据通道媒体协商成功率,缩小数据通道媒体建立时延,使IMS网络可以支持更加多样化的多媒体或交互式业务。
可以理解地,第三网元集合中可能存在不完全符合所需DC媒体信息和/或本次呼叫请求的相关信息的网元,因此为了得到更为合适的第三网元,第一网元可以基于DC媒体需求信息和/或接口需求信息等从第三网元集合中选出满足这些需求的第三网元,基于此建立连接。
在本公开实施例中,对于第一终端不做限定,可以是主叫终端,也可以是被叫终端,还可以是其他终端,本实施例中对第一终端不做限定。
可以理解地,第一网元至少基于第一终端的位置信息进行第三网元的选择,如此选出的第三网元距离第一终端的位置更近,从而使得第一网元与距
离自己更近的第三网元建立连接,这样能够缩短消息转发路径,进而缩短通信时延。
还需要说明的是,已选择的媒体功能也可以称为已选择的媒体网元,或称为已选择的媒体网络功能等等,本实施例中对媒体功能的名称不做限定,上述消息名称在未进行特殊说明之外,均可等同或替换。

一些实施例中,第一网元可以为以下之一:应用服务器(Application Server,AS)、数据通道控制功能(Data Channel Control Functionality,DCSF)、IMS网元等等;本实施例中对第一网元的名称不做限定,总之,第一网元属于网络功能消费者(NF Consumer)。
本实施例中,AS等同于IMS AS、多媒体电话AS(Multi Media Telephony,AS MMTEL)或application Server等等。本实施例对AS的名称不做限定。
本实施例中,DCSF等同于DC服务器(Data Channel Server,DCS)、DC服务控制器(Data Channel Server-Controller,DCS-C)、DC控制功能(Data Channel Control Function,DCCF)、统一控制功能(Unified Control Function,UCF)或集中控制功能(Centralized Control Function,CCF)或DC信令功能(Data Channel Signaling Function,DCSF)等等。本实施例中对DCSF的名称不做限定。
在一些实施例中,第二网元可以是网络仓储功能(Network Repository Function,NRF)或者其他网络设备。本实施例中对第二网元的名称不做限定。相应地,步骤101中的第一网元向第二网元发送第一服务发现请求;所述第
一服务发现请求至少包括所需DC媒体信息和/或本次呼叫请求的相关信息,可以描述为:IMS AS sends Nnrf_NFDiscovery_Request to NRF,with the required data channel media services related information。
在一些实施例中,第三网元可以为以下之一:数据通道媒体功能(Data Channel Media Functionality,DCMF)、DC媒体功能、DC网络功能实例、DC媒体网络功能实例、DC服务、DC媒体服务、DC媒体(Data Channel Media,DCM)、DC用户服务器(Data Channel Server-User,DCS-U)、DC媒体服务器(Data Channel Server-Media,DCS-M)、DC媒体功能(Data Channel Media Function,DMF)、媒体资源功能(Media Resource Function,MRF)、媒体资源功能处理器(Media Resource Function Processor,MRFP)、统一媒体功能(Unified Media Function,UMF)或集中媒体功能(Centralized Media Function,CMF)等等。也就是说,本实施例中对第三网元的名称不做限定。上述第三网元名称在未进行特殊说明之外,均可等同或替换。
本实施例中,DCMF等同于DCMF(data channel media function)或DCS-U(data channel server-user plane)等等。本实施例中对DCMF的名称不做限定。
在一些实施例中,所述第三网元相关信息和/或第三网元集合相关信息为以下至少之一:标识、地址信息、DC网络功能类型信息、服务实例列表信息、DC媒体功能实例信息、DC媒体网络功能、其他DC媒体服务或能力相关信息。也就是说,第三网元的相关信息可以包括上述信息中的至少之一,第三网元集合的相关信息包括了集合中各个第三网元的相关信息,每一第三网元的相关信息可以包括上述信息中的至少之一。
在一些实施例中,在缓存中没有之前确定的第三网元相关信息或第三网元集合相关信息的情况下,或者,所述之前确定的第三网元相关信息或第三网元集合相关信息的缓存时长大于时长阈值的情况下,向所述第二网元发送所述第一服务发现请求;
在缓存中保存有所述之前确定的第三网元相关信息或第三网元集合相关信息的情况下,或者,在所述缓存时长小于或等于时长阈值的情况下,将使用之前确定的第三网元相关信息或第三网元集合相关信息。
可以理解地,在缓存中保存有之前确定的第三网元相关信息或第三网元
集合相关信息,或者,在所述缓存时长小于或等于时长阈值的情况下,第一网元可以直接根据之前确定的第三网元相关信息或第三网元集合相关信息进行第三网元的选择或确定,而不需要发起第一服务发现请求;如此,就节约了第三网元的选择时间,从而能够快速建立与第三网元的连接,进而缩短通信时延。
在一些实施例中,在获知第三网元或第三网元集合的接口能力和/或接口能力列表的情况下,基于本地策略选择连接建立方式。
在一些实施例中,接口能力或接口能力列表可以是指示支持某种或多种接口协议的信息,如其记录了指示支持第一接口协议和/或第二接口协议的信息。
进一步地,在一些实施例中,第一网元在获知第三网元或第三网元集合中的各个网元支持的接口协议,可以选择更能节约通信时延的接口协议作为连接建立方式,与对应的第三网元建立连接。
示例性的,所述第一接口协议可以是基于服务的接口(Service-Based Interface,SBI),所述第二接口协议可以是H.248协议。
相应地,如若第三网元支持SBI,或者支持SBI和H.248,那么第一网元基于本地策略选择的连接建立方式可以为SBI;如此,相比于H.248,SBI不需要静态配置网元与媒体网元的连接,且有利于容量扩展和异厂家解耦,因此,选择SBI而不是H.248与第三网元建立连接,提高了与第三网元建立连接的便捷性。
接口能力和接口能力列表也可称为接口信息等等,对于接口能力和接口能力列表的名称不做限定。
在一些实施例中,第一网元在获知第三网元支持第一接口协议和第二接口协议的情况下,基于所述第一接口协议与所述第三网元建立连接;在基于所述第一接口协议与第三网元建立连接失败的情况下,所述第一网元基于所述第二接口协议与所述第三网元建立连接;其中,第一接口协议支持的连接建立方式的通信性能优于第二接口协议支持的连接建立方式。
可以理解地,第一网元首先基于第一接口协议与第三网元建立连接,如果连接失败,再尝试基于第二接口协议与第三网元建立连接;如此,再确保
通信时延的情况下提高与第三网元的连接建立的成功率,从而进一步缩短通信时延。
如上所述的实施例中,提供多样性接口选择机制,实现网络对于H.248/SBI的兼容性需求。
基于前述实施例,对于第一网元和第二网元的交互流程如下:第一网元向第二网元发送第一服务发现请求;第二网元接收第一网元发送的第一服务发现请求,所述第一服务发现请求至少包括所需DC媒体信息和/或本次呼叫请求的相关信息;第二网元确定第三网元相关信息或第三网元集合相关信息;然后第二网元向第一网元发送第一服务发现响应,所述第一服务发现响应至少包括第三网元相关信息或第三网元集合相关信息;第一网元接收第二网元返回的第一服务发现响应。
在一些实施例中,第一服务发现响应还包括第三网元或第三网元集合的接口信息,所述接口信息包括接口能力和/或接口能力列表。
在该实施例中,无论所需DC媒体信息中是否包括接口能力需求,也就是说无论第一网元是否请求获知第三网元的接口能力(或接口能力列表),第二网元都将第三网元支持的接口信息返回给第一网元;如此,便于第一网元基于第三网元的接口能力或接口能力列表等,选择合适的接口与第三网元建立连接。
示例性的,第一网元在获知第三网元或第三网元集合的接口能力和/或接口能力列表的情况下,基于本地策略选择连接建立方式;基于该连接建立方式与选出的第三网元建立连接。
示例性的,第一网元在获知第三网元支持第一接口协议和第二接口协议的情况下,基于所述第一接口协议与所述第三网元建立连接;第一网元在基于所述第一接口协议与所述第三网元建立连接失败的情况下,基于所述第二接口协议与所述第三网元建立连接。
在一些实施例中,第二网元确定第三网元集合相关信息,包括:确定满足所述所需DC媒体信息和/或本次呼叫请求的相关信息的第三网元集合;确定第三网元集合相关信息。
在一些实施例中,第二网元确定第三网元相关信息,包括:基于本地策
略确定满足所述所需DC媒体信息和/或本次呼叫请求的相关信息的第三网元;确定所述第三网元相关信息。也就是说,第二网元在本地基于所需DC媒体信息和/或本次呼叫请求的相关信息,直接选出一个第三网元,将该第三网元的相关信息返回给第一网元;这样,第一网元无需从众多第三网元中选出一个,而是直接基于第二网元返回的这一个第三网元的相关信息,与该第三网元建立连接即可。
在一些实施例中,第二网元确定第三网元相关信息或第三网元集合相关信息时,可以根据主叫号码的归属地来确定,例如,优先将距离主叫号码的归属地较近的一个第三网元作为第三网元;或者,优先将距离主叫号码的归属地较近的多个第三网元作为第三网元集合;或者,优先将在主叫号码的归属地的一个第三网元作为第三网元;或者,优先将在主叫号码的归属地的多个第三网元作为第三网元集合。
在一些实施例中,NRF至少将一个DCMF实例(instance)信息发送到IMS AS,如果接收到多个DCMF实例,IMS AS可以根据本地策略执行DCMF网络功能(Network Function,NF)选择(即:NRF sends the DCMF instance(s)information to IMS AS.In case of multiple DCMF instances are received,the IMS AS will perform DCMF NF selection based on the local policy)。
在一些实施例中,NRF可以确定一组匹配Nnrf_NFDiscovery_Request和NRF内部策略的NF实例,并发送所确定NF实例的NF配置文件。每个NF配置文件至少包含通过Nnrf_NFDiscovery_Request Response message向NF服务使用者输出所需参数(即:If allowed,the NRF determines a set of NF instance(s)matching the Nnrf_NFDiscovery_Request and internal policies of the NRF and sends the NF profile(s)of the determined NF instances.Each NF profile containing at least the output required parameters to the NF service consumer via Nnrf_NFDiscovery_Request Response message)。

图6为本公开实施例提供的IMS网络架构示意图,在一些实施例中,IMS网络所定义的媒体网络接口全部基于H.248或者媒体网关控制协议(Gateway Control protocol,Megaco)协议,DCMF需要具备新型数据通道媒体能力,且具备更加灵活的选择机制,H.248无法满足数据通道媒体所需的灵活性。
在一些实施例中,IMS技术及标准(例如3GPP TS 23.228,3GPP TS 26.114)中对于数据通道与IMS网络结合交互的接口,交互流程,以及如何注册,发现或选择DCSF,DCMF尚未定义相关流程和机制。
在一些实施例中,IMS网络采用H.248/Megaco协议进行媒体网络功能选择,数据通道媒体网络需要支持更多新型媒体功能(如渲染、翻译等),传统的IMS网络协议无法很好地满足数据通道新型媒体能力的扩展,需要对DCMF及调用该DCMF的网络功能进行创新的SBI服务化设计。
在一些实施例中,IMS网络采用标准会话初始协议(Session Initiation Protocol,SIP)和/或IMS服务控制(IMS service control,ISC)触发机制进行路由,该路由机制对于注册时非必须参与的节点不适用,该机制具有串行触发特性,造成耦合性,这使得IMS网络无法高效/按需调用DCSF(数据通道服务器)。
在一些实施例中,IMS媒体网络功能使用H.248/Megaco协议,数据通道
信令功能和DCMF之间的协议可以复用此协议以最大限度复用现网能力,也可以进行SBI扩展以解决解耦困难和扩展能力受限等问题。怎样使数据通道信令功能和DCMF之间可以灵活选择支持H.248或SBI是一个亟待解决的问题。
本公开以数据通道(DC)标准化工作为基础,提出了一种基于数据通道相关功能的注册、发现或选择机制。
