Description

一种业务处理方法及系统、设备

技术领域
本发明涉及通信技术领域，尤其涉及一种业务处理方法及系统、设备。
背景技术
网络是信息传输、接收以及共享的虚拟平台，通过它把各个点、面、体的信息联系到一起，从而实现这些资源的共享。在设备通过某一网络与另一设备连接后，两个设备之间可建立基于该网络的某一业务的会话，以建立两个设备的服务模块之间的连接和传输数据，从而实现该业务在设备间的业务传输。
随着网络技术的快速发展，多种网络接入技术相继涌现，设备可以通过多个网络与另一设备连接，上述多个网络可以是多个不同类型的网络，例如，有线网络、WI-FI(Wireless-Fidelity，无线保真)、蓝牙、NFC(Near Field Communication，近距离无线通信技术)和Powerline(输电线等，也可以是同类型但具备不同网络结构的网络，例如基于WI-FI的P2P网络和基于WI-FI的基础设施网络。
然而，目前设备之间的通信均只考虑了业务在一个网络传输的情况，在该网络出现信号质量不佳或被切换等情况时，设备间的业务会受到影响，甚至中断，而设备有关的其他网络又无法综合利用起来，浪费了多个网络的优势。

请参阅图1，本发明实施例中业务处理方法一个实施例包括：
101、当第一设备通过第二网络与第二设备连接时，第一设备向第二设备发送请求消息；
需要说明的是，当第一设备通过第二网络与第二设备连接时的应用场景可以是第一设备与第二设备刚建立基于第二网络的连接的情形，例如第一设备和第二设备使用基于第一网络的第一会话进行业务传输时，发现两者还可以建立基于第二网络的连接，于是两者建立基于第二网络的连接，在上述建立第二网络的连接完成后，可以马上执行第一设备向第二设备发送请求消息；也可以是，在第一设备与第二设备之间早已经建立有基于第二网络的连接的情形，此时可以是在满足预设的触发条件才执行第一设备向第二设备发送请求消息，例如，第一设备与第二设备之间早已经建立有基于第二网络的连接，在第一设备和第二设备使用基于第一网络的第一会话进行业务传输的过程中，发现第一会话的质量不好，于是触发第一设备向第二设备发送请求消息。

205、第一设备的ASP根据响应消息与第二设备的ASP建立第二会话；
在第一设备的ASP收到第二设备的ASP回应的响应消息后，第一设备的ASP与第二设备的ASP利用基于第二网络的一套地址建立该第二会话，即第一设备的ASP和第二设备的ASP建立有基于第二网络且对应于第一会话所对应的业务的第二会话。建立第二会话的具体过程可以包括第一设备根据该第一会话所对应的业务打开相应的端口，并通过诸如ALLOWED_PORT消息通知第二设备；同时也可以包括第一设备接收第二设备根据该第一会话所对应的业务打开相应的端口后发送的ALLOWED_PORT消息。该ALLOWED_PORT消息的具体结构可以参考现有相关标准以及后续相关标准中的规定，在本实施例中不做赘述。
206、第一设备的ASP向第一设备的服务模块发送第一报告消息；
在本实施例中，该第一报告消息用于指示第一设备与第二设备之间已经建立有该第二会话。可以理解的是，第二设备的ASP也对应向第二设备的服务模块发送一个用于指示第一设备与第二设备之间已经建立有该第二会话的报告消息。在第一设备的服务模块收到该第一报告消息后，第一设备的服务模块便可识别存在可备用的该第二会话，并根据需要通过该第二会话与第二设备的服务模块进行连接和传输数据，以实现第一会话所对应的业务在第一设备和第二设备之间的业务传输。
可以理解的是，在本实施例中，发送第一报告消息的执行时机可以是在步骤205后立即执行，也可以是在确定满足预设的第一切换条件后才执行，此处不作限定，只需保证在执行会话切换时已经完成后处理操作即可。
可选地，在步骤206之后，本实施例还可进一步包括：

在发送第一报告消息后，第一会话所对应的业务所使用的会话保持为第一会话，第二会话作为针对该第一会话所对应的业务的备用会话。当满足预设的第一切换条件时，第一设备的服务模块将第一会话所对应的业务所使用的会话由第一会话切换至第二会话，以使第一会话所对应的业务根据第二会话进行业 务传输。可以理解的是，在具体应用过程中，可以先不执行步骤206，而是：当满足预设的第一切换条件时，执行步骤206，第一设备的服务模块将第一会话所对应的业务所使用的会话由第一会话切换至第二会话，以使第一会话所对应的业务根据第二会话进行业务传输。
在本实施例中，上述预设的第一切换条件可以包括第一网络的信号质量不满足预设要求或第二网络的信号质量优于第一网络的信号质量，可以理解的是，在实际应用中，预设的第一切换条件还可以包括多种方式，例如第一设备接收到网络侧或者用户的触发指令，此处对预设的第一切换条件的具体方式不作限定。
208、当满足预设的第二切换条件时，第一设备的服务模块将第一会话所对应的业务所使用的会话由第二会话切换至第一会话；

可以理解的是，在第一设备与该第二设备建立有基于第二网络的连接时，第一设备和该第二设备可以使用一套基于第二网络的地址，即该第一设备的第二地址和该第二设备的第二地址。需要说明的是，在第一网络中，第一设备和第二设备使用基于第一网络的一套地址，在第二网络中，第一设备和第二设备使用基于第二网络的一套地址，且该基于第一网络的一套地址不同于该基于第二网络的一套地址。
在本实施例中，确认版本请求消息包含第一设备的ASP的版本信息，该确认版本请求消息用于向第二设备的ASP确认该第一设备的ASP所支持的协议版本与第二设备的ASP所支持的协议版本是否匹配。需要说明的是，在本实施例中，第一设备的ASP所支持的协议版本与第二设备的ASP所支持的协议版本匹配时的情况可以是两者所支持的协议版本一致，也可以是第二设备的ASP在向下兼容机制下其所支持的高协议版本可以匹配第二设备的ASP所支持的低协议版本。在实际应用过程中，第一设备的ASP的版本信息具体可以为ASP定义的合作协议(Coordination protocol)的版本信息。
502、第二设备的ASP根据确认版本请求消息向第一设备的ASP回应确认版本反馈消息；
在第二设备的ASP接收第一设备的ASP发送的确认版本请求消息后，第二设备的ASP对该第一设备的ASP所支持的协议版本与第二设备的ASP所支持的协议版本是否匹配进行确认，并在第一设备的ASP所支持的协议版本与第二设备的ASP所支持的协议版本匹配时，向第一设备的ASP回应确认版本反馈消息，该确认版本反馈消息包含第二设备的ASP的版本信息。相应地，在实际应用过程中，第二设备的ASP的版本信息具体可以为ASP定义的合作协议 (Coordination protocol)的版本信息，且当第一设备的ASP的版本信息与第二设备的ASP的版本信息相同时，则确认第一设备的ASP所支持的协议版本与第二设备的ASP所支持的协议版本是匹配的。
在本实施例中，步骤501和步骤502用于对第一设备的ASP和第二设备的ASP进行版本确认，以保证第一设备的ASP所支持的协议版本与第二设备的ASP所支持的协议版本匹配。可以理解的是，在某些特定的其他应用场景，也可不对第一设备的ASP和第二设备的ASP进行版本确认，例如，默认第一设备的ASP所支持的协议版本与第二设备的ASP所支持的协议版本是匹配的；而且，本实施例仅以举例的方式对如何进行版本确认进行描述，在实际应用过程中，第一设备的ASP和第二设备的ASP还可以采用其他方式进行版本确认，此处对是否进行版本确认以及如何进行版本确认不作限定。
503、第二设备的ASP接收第一设备的ASP发送的请求消息；

504、第二设备的ASP根据请求消息向第一设备的ASP回应响应消息；
在第二设备的ASP接收第一设备的ASP发送的请求消息后，第二设备的ASP根据接收到的请求消息进行响应，并向第一设备的ASP回应响应消息。在本实施例中，响应消息用于表示第二设备接受与第一设备建立该第二会话。需要说明的是，第二设备接受与第一设备建立该第二会话表明第二设备可以根据该第一会话所对应的业务打开相应的端口，并通过诸如ALLOWED_PORT消息通知第一设备。在本实施例中，响应消息可以为ADDED_SESSION消息，也可以是具有相同功能的其他名称的消息，具体此处不作限定。
505、第二设备的ASP与第一设备的ASP建立第二会话；
在第一设备的ASP收到第二设备的ASP回应的响应消息后，第二设备的ASP与第一设备的ASP利用基于第二网络的一套地址建立该第二会话，即第二设备的ASP和第一设备的ASP建立有基于第二网络且对应于第一会话所对应的业务的第二会话。建立第二会话的具体过程可以包括第一设备根据该第一会话所对应的业务打开相应的端口，并通过诸如ALLOWED_PORT消息通知第二设备；同时也可以包括第一设备接收第二设备根据该第一会话所对应的业务打开相应的端口后发送的ALLOWED_PORT消息。该ALLOWED_PORT消息的具体结构可以参考现有相关标准以及后续相关标准中的规定，，在本实施例中不做赘述。
506、第二设备向第一设备的服务模块发送第一报告消息；
在本实施例中，该第一报告消息用于指示第一设备与第二设备之间已经建立有该第二会话。可以理解的是，第一设备的ASP也对应向第一设备的服务模块发送一个用于指示第一设备与第二设备之间已经建立有该第二会话的报告消息。在第二设备的服务模块收到该第一报告消息后，第二设备的服务模块便可识别存在可备用的该第二会话，并根据需要通过该第二会话与第二设备的服务模块进行连接和传输数据，以实现第一会话所对应的业务在第一设备和第二设备之间的业务传输。
可以理解的是，在本实施例中，发送第一报告消息的执行时机可以是在步骤205后立即执行，也可以是在确定满足预设的第一切换条件后才执行，此处不作限定，只需保证在执行会话切换时已经完成后处理操作即可。
可选地，在步骤506之后，本实施例还可进一步包括：
507、当满足预设的第一切换条件时，第二设备的服务模块将第一会话所对 应的业务所使用的会话由第一会话切换至第二会话；
在发送第一报告消息后，第一会话所对应的业务所使用的会话保持为第一会话，第二会话作为针对该第一会话所对应的业务的备用会话。当满足预设的第一切换条件时，第二设备的服务模块将第一会话所对应的业务所使用的会话由第一会话切换至第二会话，以使第一会话所对应的业务根据第二会话进行业务传输。可以理解的是，在具体应用过程中，可以先不执行步骤206，而是：当满足预设的第一切换条件时，执行步骤206，第一设备的服务模块将第一会话所对应的业务所使用的会话由第一会话切换至第二会话，以使第一会话所对应的业务根据第二会话进行业务传输。
在本实施例中，上述预设的第一切换条件可以包括第一网络的信号质量不满足预设要求或第二网络的信号质量优于第一网络的信号质量，可以理解的是，在实际应用中，预设的第一切换条件还可以包括多种方式，例如第二设备接收到网络侧或者用户的触发指令，此处对预设的第一切换条件的具体方式不作限定。
508、当满足预设的第二切换条件时，第二设备的服务模块将第一会话所对应的业务所使用的会话由第二会话切换至第一会话；
在第二设备将第一会话所对应的业务所使用的会话由第一会话切换至第二会话之后，当满足预设的第二切换条件时，第二设备的服务模块将第一会话所对应的业务所使用的会话由第二会话切换至第一会话，以使第一会话所对应的业务根据第一会话进行业务传输。

本发明实施例提供的技术方案中，当第一设备通过第二网络与第二设备连接时，第二设备的ASP接收第一设备的ASP发送的请求消息，该请求消息中包含第一协作信息，该第一协作信息用于表示第二会话和第一会话对应于同一业务，并在向第一设备的ASP回应响应消息后，与第一设备的ASP建立该第二会话，使得第二设备的ASP与第一设备的ASP之间建立基于第二网络且对应于第 一会话所对应的业务的第二会话，第二设备的服务模块在接收第二设备的ASP发送的第一报告消息后便可根据需要通过第二会话与第一设备的服务模块进行连接和传输数据，以实现第一会话所对应的业务在第一设备和第二设备之间的业务传输。本发明实施例通过在设备间建立针对同一业务且基于第二网络的第二会话，可在第一网络出现信号质量不佳或被切换等情况时，设备间的第一会话所对应的业务可在第二网络中继续运行，以保证业务传输的可靠性，有效提高业务传输质量，且能够提高网络资源利用率，避免网络资源的浪费。
更进一步地，本发明实施例可根据预设的第一切换条件和预设的第二切换条件，将第一会话所对应的业务在基于第一网络的第一会话和基于第二网络的第二会话中切换，为业务使用网络的选择提供了更大的灵活度，并保证业务在不同网络间的无缝切换，从而提高用户体验。
