具体实施方式
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，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通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，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不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，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的建立会话的方法、装置、电子设备及存储介质进行详细地说明。
图1示出本申请的一个实施例提供的一种建立会话的方法，该方法可以由用户面功能(User Plane Function，UPF)设备执行等。换言之，该方法可以由安装在UFP设备的软件或硬件来执行，该方法包括如下步骤。
步骤102：接收第二包转发控制协议PFCP会话的建立请求消息。
具体的，在用户终端(User Equipment，UE)发起专网业务的访问请求之后，会话管理功能(Session Management Function，SMF)可以向策略控制功能(Policy Control Function，PCF)请求下发策略信息，PCF接收到SMF发送的请求后可以向SMF下发策略信息，其中，该策略信息包括支持专网业 务的相关信息，SMF在接收到PCF下发的策略信息后可以再发起用户面建立请求以建立UPF，该UPF用于处理和转发公网业务报文以及专网业务报文，UPF在建立成功之后可以向SMF发送建立成功响应消息。
在用户终端发起访问专网业务的请求之后，由于用户终端发起的访问专网业务的专网业务报文在到达UPF之前需要通过公网会话传输，因此，在UPF中需要建立公网会话接收专网业务报文，UPF可以接收SMF发送的第一包转发控制协议(Packet Forwarding Control Protocol，PFCP)会话的建立请求，在UPF中建立第一PFCP会话，该第一PFCP会话用于接收和转发公网业务报文，也可以用于接收专网业务报文。
UPF可以接收SMF发送的第二PFCP会话的建立请求消息，建立第二PFCP会话，该第二PFCP会话即用于转发专网业务报文的专网会话，其中，第二PFCP会话的建立请求消息中携带有第一PFCP会话的信息，UPF会根据第一PFCP会话的信息建立第二PFCP会话，因此，第一PFCP会话与第二PFCP会话会具有关联关系。
步骤104：根据所述第一PFCP会话的信息，确定所述第一PFCP会话对应的所述UPF中的第一报文转发单元PFU。
具体的，UPF由多个包转发单元(Packet Forward Unit，PFU)组成，每个PFCP会话可以按照会话端点标识(Session Endpoint Identifier，Seid)并以预设算法对应在一个PFU上，每个PFCP会话转发报文时就在其所在的PFU处处理并转发。
本申请实施例中，第一PFCP会话的信息中可以包括第一PFCP会话对应的Seid或者其他可以用于标识第一PFCP会话所对应的PFU的信息，在此不对第一PFCP会话的信息作具体限定，因此，UPF可以根据第一PFCP会话的信息，在UPF中确定与第一PFCP会话对应的第一PFU。
步骤106：将所述第一PFU确定为所述第二PFCP会话对应的所述UPF中的第二PFU。
具体的，在UPF中确定与第一PFCP会话对应的第一PFU之后，可以将该第一PFU确定为第二PFCP会话对应的第二PFU，并在第二PFU上建立第二PFCP会话，该第二PFCP会话即用于处理和转发专网业务报文。
步骤108：发送携带所述第二PFU的信息的所述第二PFCP会话的建立响应消息。
具体的，在建立第二PFCP会话之后，UPF可以向SMF发送携带有第二PFU的信息的第二PFCP会话的建立响应消息，以表示在UPF中完成建立第二PFCP会话。
在本申请实施例中，通过接收第二包转发控制协议PFCP会话的建立请求消息，第二PFCP会话的建立请求消息中携带第一PFCP会话的信息，第一PFCP会话与第二PFCP会话具有关联关系；根据第一PFCP会话的信息，确定第一PFCP会话对应的UPF中的第一报文转发单元PFU；将第一PFU确定为第二PFCP会话对应的UPF中的第二PFU；发送携带第二PFU的信息的第二PFCP会话的建立响应消息，使得接收专网业务报文的第一PFCP会话和发送专网业务报文的第二PFCP会话在同一个PFU上，专网业务报文的接收和专网业务报文的转发都在同一个PFU上进行，避免了在UPF内部再进行专网业务报文的转发，进而避免了UPF内部的损耗，解决了UPF性能损耗严重的问题，提升了UPF的性能。
在一种实现方式中，所述第一PFCP会话的信息中的第一字段用于表示第一PFCP会话的第二字段与所述第二PFCP会话的第三字段相关联。
具体的，SMF向UPF发送第二PFCP会话的建立请求消息携带的第一PFCP会话的信息，其中，该第一PFCP会话的信息包括第一字段，该第一字段可以包括第一PFCP会话的第二字段，该第二字段可以为第一PFCP会话对应的Seid，或者是其他可以确定第一PFCP会话对应的PFU的字段，这样，在UPF接收到第二PFCP会话的建立请求消息的情况下，可以根据第一PFCP会话对应的第二字段找到与第一PFCP会话对应的PFU，并在第一PFCP会 话对应的PFU上建立第二PFCP会话，那么第二PFCP会话对应的第三字段也对应着第一PFCP会话对应的PFU，即一PFCP会话的第二字段与所述第二PFCP会话的第三字段相关联，第一PFCP会话和第二PFCP会话建立在同一个PFU上。
具体的，通过第一PFCP会话的信息中的第一字段用于表示第一PFCP会话的第二字段与第二PFCP会话的第三字段相关联，使得UPF建立的第一PFCP会话和第二PFCP会话在同一个PFU上，专网业务报文的接收和专网业务报文的转发都在同一个PFU上进行，避免了在UPF内部再进行专网业务报文的转发，进而避免了UPF内部的损耗，解决了UPF性能损耗严重的问题，提升了UPF的性能。
在一种实现方式中，所述第一PFCP会话为用户的公网PFCP会话，所述第二PFCP会话为所述用户的专网PFCP会话。
具体的，上述的第一PFCP会话可以为公网PFCP会话，即在UPF中，通过第一PFCP会话可以接收用户发送的业务请求报文，在用户发起的业务请求为公网业务请求时，可以通过第一PFCP会话接收公网业务请求的公网业务报文，并通过N6接口将公网业务报文传输至公网，上述的第二PFCP会话可以为用户的专网PFCP会话，通过将第一PFCP会话和第二PFCP会话建立在同一PFU上，这样，可以通过第一PFCP会话接收用户终端发送的专网业务报文，通过第二PFCP会话可以将专网业务请求报文转发至专网，避免了在UPF内部再进行专网业务报文的转发，进而避免了UPF内部的损耗，解决了UPF性能损耗严重的问题，提升了UPF的性能。
在一种实现方式中，在所述接收第二包转发控制协议PFCP会话的建立请求消息之前，所述方法还包括：接收用于识别专网业务的探测规则；接收所述用户发送的业务报文；在所述用户发送的业务报文与所述探测规则匹配的情况下，向会话管理功能SMF发送目标通知，所述第二PFCP会话的建立请求消息是所述SMF在接收到目标通知的情况下发送的。
具体的，PCF在接收到SMF发送的请求后可以向SMF下发策略信息，其中，该策略信息包括了支持专网业务的相关信息，SMF在接收到PCF下发的策略信息后，会根据策略信息中支持专网业务的相关信息构造探测规则，该探测规则用于识别专网的业务，因此，在建立UPF时，UPF可以接收该探测规则，在接收到用户终端发送的业务报文的情况下，UPF可以通过探测规则和业务报文进行匹配，确定用户所要访问的专网业务，若匹配成功，则确定用户所要访问的专网业务，UPF可以向SMF发送目标通知，通知SMF存在用户发送的专网业务报文，SMF在接收到该通知后，确定需要进行专网业务报文的转发，将第二PFCP会话的建立请求消息发送至UPF。
这样，在接收用于识别专网业务的探测规则；接收用户发送的业务报文；在用户发送的业务报文与探测规则匹配的情况下，向会话管理功能SMF发送目标通知，第二PFCP会话的建立请求消息是SMF在接收到目标通知的情况下发送的，能够准确地识别用户是否访问专网业务，并在确定用户发送的业务报文为专网业务的情况下，建立第二PFCP会话以对专网业务报文进行转发，实现了用户访问专网业务。
在一种实现方式中，通过所述第二PFCP会话转发所述业务报文。
具体的，在建立第二PFCP会话之后，若通过第一PFCP接收到的业务报文为专网业务报文的，可以通过第二PFCP会话进行业务报文的转发，图2示出的是本申请实施例提供一种报文传输的示意图，如图2所示，UPF 210中包括多个PFU，由于第二PFCP会话和接收业务报文的第一PFCP会话均建立在同一个PFU 220上，这样，专网业务报文的接收和专网业务报文的转发都在同一个PFU上进行，避免了在UPF内部再进行专网业务报文的转发，进而避免了UPF内部的损耗，解决了UPF性能损耗严重的问题，提升了UPF的性能。
图3是本申请实施例提供的一种专网业务访问的流程示意图，如图3所示，专网业务访问的流程包括以下步骤。
步骤301：用户发起公网会话建立请求。
SMF可以接收用户终端发起的会话建立请求。
步骤302：请求策略信息。
SMF在接收到用户发起的公网会话建立请求之后，可以向PCF请求下发策略信息。
步骤303：下发策略信息。
PCF在接收到SMF的请求后，向SMF中下发策略信息，其中，该策略信息包括支持专网业务的相关信息。
步骤304：识别并缓存策略信息。
SMF接收到PCF下发的策略信息后，可以根据专网业务的相关信息构造探测规则，该探测规则用来识别针对专网的业务。
步骤305：通知UPF建立，安装探测规则。
SMF发起UPF建立请求以建立UPF，并在UPF建立请求中携带有探测规则，在UPF建立并且安装完成探测规则之后，UPF发送建立响应消息至SMF。
步骤306：完成公网会话建立流程。
具体的，在UPF建立之后，完成公网会话的建立。
步骤307：接收专网业务报文。
UPF可以接收用户发送的专网业务报文，该专网业务报文用于访问专网业务。
步骤308：根据探测规则匹配业务报文。
UPF在接收到用户发送的专网业务报文之后，可以将专网业务报文和探测规则进行匹配，匹配成功则识别用户需要访问的专网业务。
步骤309：通知SMF有专网业务报文。
UPF通知SMF，指示此用户需要访问专网业务，即存在专网业务报文。
步骤310：触发专网会话建立请求。
SMF收到UPF发送的通知，决策需要进行专网业务分流，将触发创建一个信的专网会话，用来疏通专网业务数据通道。
步骤311：发送专网会话建立请求。
SMF向UPF发送PFCP会话建立请求(PFCP Session Establishment Request)，该PFCP会话建立请求增加了扩展字段，例如下表中的RelatedUpfSeid，该扩展字段携带了公网会话的Seid，UPF在接收到PFCP会话建立请求之后，会选择RelatedUpfSeid所在的PFU建立专网会话，保证公网会话和专网会话在同一个PFU上。
步骤312：回复专网会话建立响应消息。
UPF回复PFCP会话建立响应消息(Session Establishment Response)至SMF。
步骤313：继续完成专网会话的创建过程。
在专网会话完成之后，至此SMF申请专网UPF资源完成，用于可以使用专网业务。
步骤314：转发专网业务报文。
在专网会话建立完成之后，在UPF中可以通过专网会话转发专网业务报文至专网业务服务器。
这样，接收专网业务报文的公网会话和转发专网业务报文的专网会话都建立在同一个PFU上，即在同一个PFU上，即可以通过公网会话进行专网业务报文的接收，也可以通过专网会话进行专网业务报文的转发，避免了在 UPF内部再进行专网业务报文的转发，进而避免了UPF内部的损耗，解决了UPF性能损耗严重的问题，提升了UPF的性能。
