需要说明的是，本公开的一些实施例中并不限定终端11、第一网元12和第二网元13的具体类型。
请参见图2，图2是本公开的一些实施例提供的一种IMS信息传输方法的流程图，该方法应用于第一终端，如图2所示，包括以下步骤：
步骤S201、发送NAS请求，所述NAS请求携带有IMS信息；
其中，所述第一终端在发送所述NAS请求之前已经注册到IMS。
其中，上述NAS请求可以是终端在空闲态或者非激活态发送的NAS请 求，当然，也可以是终端在连接态发送的NAS请求。
在上述步骤中，由于在上述NAS请求携带有IMS信息，这样可以支持在发送IMS信息之前可以不激活或者建立与移动网络的连接，以降低IMS信息处理(如传输)的时长。因为，发送NAS请求可以是在未激活或者建立与移动网络的连接的情况下进行发送。
可选的，上述NAS请求消息包括：
业务请求或者协议数据单元(Protocol Data Unit，PDU)会话更新请求。
其中，上述业务请求可以服务请求(Service Request)消息或者其他用于激活或者建立无线空口连接的消息。
这样可以实现通过业务请求或者PDU会话更新请求发送IMS信息，以实现IMS信息与业务请求或者与PDU会话更新请求的复用，以降低发送IMS信息的时长。
本公开的一些实施例中，上述IMS信息可以是与IMS会话建立相关的信息，以通过上述IMS信息实现快速建立IMS会话。当然，对此不作限定，上述IMS信息可以是在IMS中可以传输中任何信息。
可选的，上述IMS信息包括如下至少一项：
IMS消息、媒体信息。
其中，上述IMS消息可以是IMS呼叫建立请求，比如：SIP INVITE消息，对此不作限定，例如：上述IMS消息可以是IMS中第一终端可以向第二终端发送任何IMS消息，其中，第二终端可以是上述第一终端之外的某一终端。
而上述媒体信息可以是表示媒体描述信息，例如：该媒体信息可以反映IMS呼叫建立请求中携带的媒体描述信息，具体可以用于辅助IMS会话建立的相关信息。例如：所述媒体信息可以包括如下至少一项：
媒体类型、会话带宽、媒体类型的带宽、媒体连接一端的地址。
其中，上述媒体类型可以是一个或者多个媒体类型，且上述媒体类型的带宽可以是某一个或者多个媒体类型的带宽。而上述媒体连接一端的地址可以是IMS信息相关的媒体连接的某一终端的地址，如上述第一终端的地址。
通过上述媒体信息可以让网元(例如：会话管理功能)提前预留资源， 以快速建立IMS会话。
本公开的一些实施例中，上述第一终端在发送所述NAS请求之前已经注册到IMS可以是，第一终端在连接态的情况下，第一终端与移动网络建立连接以发起IMS注册过程，以注册到IMS。例如：第一终端在空闲态发送上述NAS请求，但终端进入该空闲态之前，在连接态的情况下注册到IMS。
由于第一终端在发送所述NAS请求之前已经注册到IMS，之前发送IMS信息之前不需要再发起IMS注册过程，以降低终端发送IMS信息的时长。
可选的，所述发送NAS请求之前，所述方法还包括：
接收来自网络的IMS指示，所述IMS指示用于指示所述网络支持的IMS会话建立方式。
其中，上述接收来自网络的IMS指示可以是终端接收CN网元发送的IMS指示，如接收SMF发送的IMS指示，以指示该SMF支持的IMS会话建立方式。
需要说明的是，由于本公开的一些实施例中，可以降低发送IMS信息的时长，也就可以实现快速建立IMS会话，也就是说，本公开的一些实施例中IMS会话建立方式为快速IMS会话建立，从而本公开的一些实施例中的IMS会话建立方式可以称作快速IMS会话建立，即上述IMS指示用于指示所述网络支持的IMS会话建立方式可以是，IMS指示用于指示上述网络支持快速IMS会话建立。例如：SMF可以通过信令消息(比如Service Accept消息)向终端发送IMS指示，用于指示SMF支持快速IMS会话建立。
当然，如果某网络功能不支持快速IMS会话建立，则该网络功能不发送IMS指示，以表示其不支持快速IMS会话建立。
上述实施方式中，由于第一终端接收到上述IMS指示，从而可以确定网络支持的IMS会话建立方式，进而可以根据实际情况通过相应方式发送IMS信息，以避免第一终端与网络侧之间不一致，导致的传输浪费。
例如：第一终端可以依据所述IMS指示决定在所述NAS请求中携带所述IMS信息。具体可以是，在上述IMS指示网络支持快速IMS会话建立，且第一终端也支持快速IMS会话建立，则在NAS请求中携带所述IMS信息，以实现快速建立IMS会话。如果，上述IMS指示网络支持快速IMS会话建 立，但第一终端不支持快速IMS会话建立，或者网络没有向终端发送上述IMS指示，或者发送的IMS指示用于指示网络不支持快速IMS会话建立，则不在上述NAS请求中携带上述IMS信息，以避免在NAS请求中携带IMS导致的资源浪费或者传输错误。
本公开的一些实施例中，发送NAS请求，所述NAS请求携带有IMS信息；其中，所述第一终端在发送所述NAS请求之前已经注册到IMS。这样由于通过NAS携带IMS信息，从而支持在发送IMS信息之前可以不激活或者建立与移动网络的连接，以降低IMS信息处理的时长。
请参见图3，图3是本公开的一些实施例提供的另一种IMS信息传输方法的流程图，该方法应用于第一网络功能，如图3所示，包括以下步骤：
步骤S301、接收第一请求消息，所述第一请求消息携带有IMS信息；
步骤S302、执行IMS会话的相关操作。
其中，上述第一网络功能可以是CN网元，例如：SMF。
上述第一请求消息可以是接收接入管理功能发送的第一请求消息，或者其他网络功能，如接收IMS控制功能发送的第一请求消息。上述第一请求消息可以是PDU上下文更新请求，或者其他请求。
而上述第一请求消息携带的IMS信息可以是来自第一终端的IMS信息，例如：所述IMS信息可以包含如下至少一项：
IMS消息、第一媒体信息。
而上述第一媒体信息包括如下至少一项：
媒体类型、会话带宽、媒体类型的带宽、媒体连接一端的地址。
需要说明的是，本实施例中的IMS信息可以参见图2所示的实施例中的相应说明，此处不作赘述。
而上述执行IMS会话的相关操作可以是，执行IMS会话建立相关的操作，例如：执行为IMS会话预留资源的操作。或者可以是向IMS网络发送所述IMS信息，如IMS消息。
本实施例中，通过上述步骤可以实现在接收到上述IMS信息后，即可以执行IMS会话的相关操作，而不需要等待第二终端的针对上述IMS信息的响应才执行IMS会话的相关操作，从而降低IMS信息的处理时长。
可选的，所述执行IMS会话的相关操作，包括：
向第二网络功能发送IMS策略创建请求，其中，所述IMS策略创建请求携带有所述IMS信息。
其中，上述第二网络功能可以是SN网元，例如：IMSCF。
该实施方式中，由于第二网络功能发送IMS策略创建请求，且IMS策略创建请求携带有所述IMS信息，从而第二网络功能可以依据该IMS信息响应IMS策略创建请求，如向第三网络功能发送策略授权创建请求，或者创建IMS策略。需要说明的是，本公开的一些实施例中，并不限定第二网络功能响应IMS策略创建请求的方式，可以采用协议中已定义的或者后续协议版本定义的响应方式。
进一步的，在发送IMS策略创建请求，第一网络功能还可以接收到第二网络功能发送的IMS策略创建响应，以表示第二网络功能已经成功响应IMS策略创建请求。该IMS策略创建响应可以包括上述IMS消息。
该实施方式中，通过上述IMS策略创建请求可以实现，快速建立IMS会话。
可选的，所述执行IMS会话的相关操作，包括：
向第三网络功能发送策略授权创建请求，所述策略授权创建请求携带有第二媒体信息，其中，所示第二媒体信息基于所述IMS信息生成，且所述第二媒体信息包含以下至少一项：
带宽、媒体连接一端的地址。
其中，上述第二媒体信息可以是用于创建满足IMS会话需求的移动网络连接的媒体参数。
其中，上述第三网络功能可以是CN网元，例如：策略控制功能。
另外，向第三网络功能发送策略授权创建请求后，第三网络功能会响应该策略授权创建请求。需要说明的是，本公开的一些实施例中，并不限定第三网络功能响应策略授权创建请求的方式，可以采用协议中已定义的或者后续协议版本定义的响应方式。
进一步的，上述第一网络功能还可以接收第三网络功能发送的策略授权创建响应，该响应表示第三网络功能已经成功响应策略授权创建。
该实施方式中，通过上述IMS策略创建请求可以实现，快速建立IMS会话。
可选的，所述IMS信息包含IMS消息，所述执行IMS会话的相关操作，包括：
向第四网络功能发送所述IMS消息。
其中，上述第四网络功能可以是CN网元，例如：代理IMS会话控制功能。
该实施方式中，向第四网络功能发送所述IMS消息，从而第四网络功能可以向第二终端转发该IMS消息。当然，代理IMS会话控制功能可以暂不转发IMS消息，而是等到接收到用户面管理事件通知后，再依据该事件决定是否转发IMS消息给第二终端，其中，上述用户面管理事件通知可以用于通知IMS媒体用户面资源预留完。
可选的，所述向代理IMS会话控制功能发送所述IMS消息之后，所述方法还包括：
所述终端的IMS媒体用户面资源预留完成，向所述第四网络功能发送资源预留完成通知消息。
通过上述资源预留完成通知消息可以及时通知IMS媒体用户面资源预留完成，以使得第四网络功能及时向第二终端转发上述IMS消息，以快速建立IMS会话。
可选的，所述接收第一请求消息之前，所述方法还包括：
向所述终端发送IMS指示，所述IMS指示用于指示所述第一网络功能支持的IMS会话建立方式。
其中，上述IMS指示可以是参见图2所示的实施例中的IMS指示，此处不作赘述，且可以达到相同有益效果。
本实施例中，可以实现在接收到上述IMS信息后，即可以执行IMS会话的相关操作，而不需要等待第二终端的针对上述IMS信息的响应才执行IMS会话的相关操作，从而降低IMS信息的处理时长。
请参见图4，图4是本公开的一些实施例提供的另一种IMS信息传输方法的流程图，该方法应用于第二网络功能，如图4所示，包括以下步骤：
步骤S401、接收来自第一网络功能的IMS信息；
步骤S402、向第三网络功能发送第二媒体信息，其中，所述第二媒体信息基于所述IMS信息生成。
其中，上述第二网络功能可以是CN网元，如IMSCF。上述第三网络功能可以是CN网元，例如：策略控制功能。
上述IMS信息可以参见图2和图3所示的IMS信息，此处不作赘述，例如：所述IMS信息可以包含如下至少一项：IMS消息、第一媒体信息。
上述第二媒体信息可以是参见图3所示的实施例中的第二媒体信息，此处不作赘述。
本实施例中，通过上述步骤可以实现在未接收第二终端针对上述IMS信息的响应时，发送上述第二媒体信息，以便第三网络功能快速响应第二媒体信息，以降低IMS信息处理的时长。
可选的，所述向第三网络功能发送第二媒体信息包括：
向所述向第三网络功能发送策略授权创建请求，所述策略授权创建请求携带有所述第二媒体信息；
所述第一IMS信息包含所述IMS消息，所述方法还包括：
接收所述第三网络功能发送的策略授权创建响应，并向所述第一网络功能发送所述IMS消息。
其中，上述策略授权创建请求和策略授权创建响应可以参见图3所示的实施例中的相应说明，此处不作赘述。
该实施方式中，由于向所述第一网络功能发送所述IMS消息，从而可以通过该IMS消息准确地告诉上述IMS信息已经处理完成，以使得上述第一网络功能可以快速进行其他处理，以进一步降低IMS信息处理的时长。
本实施例中，可以实现在未接收第二终端针对上述IMS信息的响应时，发送上述第二媒体信息，以便第三网络功能快速响应第二媒体信息，以降低IMS信息处理的时长。
下面以第一终端为UE，且在空闲态发送IMS消息，且IMS消息为IMS呼叫建立请求进行举例说明：
在一个实施例中，如图5所示，可以包括以下步骤：
步骤200：UE处于空闲态，UE在注册到IMS后可以发起IMS呼叫，UE可以进入连接态与移动网络建立连接以发起IMS注册过程，UE进入空闲态前，服务于UE的IMS业务的SMF(即本实施例中的SMF)可以通过信令消息(比如Service Accept消息)向UE发送IMS指示，用于指示SMF支持快速IMS会话建立。
步骤201：UE通过移动网络的基站向移动网络的接入管理功能(AMF)发送业务请求，比如发送Service Request消息，以激活无线空口连接，消息携带IMS呼叫建立请求，比如SIP INVITE消息，业务请求消息还可携带媒体信息，该媒体信息反映了步骤201的IMS呼叫建立请求中携带的媒体描述信息，包含媒体类型，还可包含会话带宽或针对某个媒体类型的带宽，还可包含媒体连接地址等。UE可以判断是否接收到过IMS指示来判断是否在业务请求中携带IMS相关信息。

另一个实施例为，SMF和IMSCF合设，此时IMSCF就是SMF。
步骤205：PCF向SMF发送会话管理策略更新请求，比如发送SM Policy Association Modification Request，携带IMS会话的服务质量(Quality of Service， QoS)参数，比如QoS优先级信息、带宽等，SMF向PCF发送会话管理策略更新响应，比如发送SM Policy Association Modification Response。
步骤206：步骤204后，IMSCF向SMF发送IMS策略创建响应，比如发送Nims_PolicyCreate Response，如果步骤203中包含IMS呼叫建立请求，则IMS策略创建响应携带IMS呼叫建立请求。
另一个实施例为，SMF和IMSCF合设，此时没有步骤206。
步骤207：如果步骤202或步骤206中包含IMS呼叫建立请，SMF向P-CSCF发送IMS呼叫建立请求，IMS呼叫建立请求可以经过UPF转发，P-CSCF可以暂不转发IMS呼叫建立请求，而是等到接收到步骤217中的用户面管理事件通知后，再依据该事件决定是否转发IMS呼叫建立请求给目标用户。
另一个实施例为，P-CSCF和IMSCF合设，此时没有步骤207，如果步骤202中包含IMS呼叫建立请求，则步骤203携带IMS呼叫建立请求，步骤206为可选。
步骤208：SMF向用户面功能(UPF)发送N4接口会话更新请求，比如发送N4 Session Modification Request，可携带基于会话连接一端的连接地址信息(即UE的连接地址信息，包括IP地址和端口号)的规则，用于UPF依据规则处理下行数据报文，并接收UPF发送的携带UPF接收地址信息的N4接口会话更新响应，比如N4 Session Modification Response。

步骤216：SMF向AMF发送PDU上下文更新响应，比如发送Nsmf_PDUSession_UpdateSMContext Response。
步骤217：步骤216后，UE的IMS媒体用户面资源预留完成，可选地，SMF可以向P-CSCF发送用户面管理事件通知，比如发送User Plan Management Notification消息，P-CSCF可以依据该消息判断UE的IMS媒体用户面资源是否预留成功，并依据该消息决定是否转发收到的IMS呼叫建立请求给目标用户。
步骤218：P-CSCF将接收到的IMS呼叫建立响应或IMS振铃消息发送给UE，消息通过UPF和基站的透明转发，如果是IMS振铃消息，步骤211后(IMS振铃消息可能会早于步骤211到达UE)，UE会播放提醒声音，提示用户IMS呼叫连接建立完成，目标用户正在振铃。
其中，上述IMS振铃消息可能会早于步骤211到达UE可以是P-CSCF接收到IMS呼叫请求后转发了IMS呼叫请求，从而向UE发送IMS振铃消息。
步骤219：如果P-CSCF收到来自目标用户的终端的媒体描述信息，P-CSCF向策略控制功能PCF发送策略授权创建请求，比如发送Policy Authorization Create Request，携带IMS会话的媒体参数，用于创建满足IMS会话需求的移动网络连接，包括媒体类型、会话连接两端的地址信息等，PCF向P-CSCF发送策略授权创建响应，比如发送Policy Authorization Create Response。
步骤220：PCF发现策略信息更新了，比如增加了对端的连接地址信息， 或减少了媒体类型等，PCF向SMF发送会话管理策略更新请求，比如发送SM Policy Association Modification Request，携带更新的IMS会话策略参数，比如对端连接地址信息，媒体类型减少后剩余的QoS优先级信息、带宽等，SMF向PCF发送会话管理策略更新响应，比如发送SM Policy Association Modification Response。

在另一个实施例中，该实施例中主要描述终端通过移动网络接受IMS呼叫建立的流程，可以如图6所示，包括以下步骤：
步骤301：UE已经在IMS网络中完成注册过程，比如向IMS网络发起SIP Registration消息，消息经过IMS网络的P-CSCF转发，并接收到来自IMS网络的经过P-CSCF转发的SIP 200 OK消息。UE处于连接态，服务于UE的IMS业务的移动网络中的SMF(即本实施例中的SMF)可以通过信令消息(比如Service Accept消息)向UE发送IMS指示，用于指示SMF支持快速IMS会话建立。
步骤302：P-CSCF接收到来自主叫用户的IMS会话建立请求，比如SIP INVITE消息，IMS会话建立请求还携带主叫用户的终端的媒体描述信息(包括媒体类型、媒体连接地址等信息)，P-CSCF向目标用户的终端UE转发该请求，该请求经过UPF和基站的透明转发。

步骤309：如果步骤305或步骤308中包含IMS呼叫建立响应消息，SMF向P-CSCF发送IMS呼叫建立响应消息，IMS呼叫建立响应消息可以经过UPF转发，P-CSCF可以暂不转发IMS呼叫建立响应，而是等到接收到步骤219中的用户面管理事件通知后，再依据该事件决定是否转发IMS呼叫建立响应给主叫用户。
另一个实施例为，P-CSCF和IMSCF合设，此时没有步骤309，如果步骤304中包含IMS呼叫建立响应消息，则步骤305携带IMS呼叫建立响应消 息，步骤308为可选。
步骤310：SMF向用户面功能(UPF)发送N4接口会话更新请求，比如发送N4 Session Modification Request，可携带基于会话连接一端的连接地址信息(即UE的连接地址信息，包括IP地址和端口号)的规则，用于UPF依据规则处理下行数据报文，并接收UPF发送的携带UPF接收地址信息的N4接口会话更新响应，比如N4 Session Modification Response。
