Description

本发明涉及通信技术领域，尤其涉及一种路径处理方法、装置及终端。
背景技术
核心网是演进分组系统(Evolved Packet System,EPS)中的重要组成部分，核心网的关键逻辑网元可包括移动性管理实体(Mobility Management Entity，MME)、服务网关(Serving Gateway,S-GW)、分组数据网络网关(Packet Data Network Gateway,P-GW)以及归属用户服务器(Home Subscriber Server,HSS)等。P-GW是连接外部数据网的网关，是接入网与非接入网之间的用户面锚点，即用户设备可以通过P-GW创建分组数据网(Packet data network,PDN)连接访问外部数据网，当用户设备发生移动时，用户设备的IP地址及上下行路径均需锚定在转发面设备，如P-GW处，以保证用户移动时业务的连续性。
然而，在实践中发现，用户设备移动时其业务报文传输路径均需锚定在源转发面网元，从而引起上下行路径较长，导致网络延迟较大。而随着通信技术的发展，用户设备的宽带接入技术具有巨大的进步，如无线保真(Wireless-Fidelity,Wi-Fi)，全球微波互联接入(Worldwide Interoperability for Microwave Access,WiMAX)，第三代或第四代移动通信技术3G/4G等，并且EPS系统也支持用户设备与PDN网络的多PDN连接，使得用户设备可以同时具有到达目标节点的多个PDN连接，但对于具有多PDN连接的用户设备来说，如何从中选择合适的PDN连接提高业务报文的传输质量是一个亟待解决的问题。

附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，图1是本发明实施例公开的一种用户设备移动后业务流传输路径的示意图。其中，图1所示的用户设备可以是任何移动或便携式电子设备，包括但不限于移动电话、移动电脑、平板电脑、个人数字助理(Personal Digital Assistant,PDA)、媒体播放器、智能电视，以及上述两项或两项以上的组合等，本发明实施例不作限定；图1所示的转发面网元可以包括服务网关(Serving Gateway,S-GW)、分组数据网络网关(Packet Data Network Gateway,P-GW)或者S-GW/P-GW的转发面网元，其中，服务网关(Serving Gateway,S-GW)是接入网络内的一个数据锚点，用于完成分组数据的路由和转发，是本地移动性管理的锚点；分组数据网络网关(Packet Data Network Gateway,P-GW)是连接外部数据网的网关，是接入网络与非接入网络之间的用户面锚点，用户设备需通过转发面设备创建PDN连接访问外部的分组数据网络，这些分组数据网络可以是互联网、虚拟私有网络、IP多媒体业务网络或者运营商提供的无线应用协议网络等；S-GW/P-GW的转发面网元是S-GW/P-GW控制和转发分离之后具有转发面功能的逻辑单元，用于转发用户报文。如图1所示，用户设备在移动过程中传输业务报文的业务流传输路径均需锚定在移动前锚定的源转发面网元(即，转发面网元1)处，即业务报文需通过转发面网元2以及转发面网元1接入到PDN网络中，导致移动后通过该PDN连接发起的业务流路径较长，业务传输质量差。
为解决上述问题，EPS系统可以支持用户设备与PDN网络的多PDN连接，可以将业务报文迁移到合适的PDN连接上缩短网络延迟，改善业务传输质量。请参阅图2，图2是本发明实施例公开的一种多PDN连接的系统架构示意图，如图2所示，该多PDN连接的系统架构包括用户设备、用户设备在当前位置所关 联的无线接入点(该无线接入点包括3G的无线接入点1、4G的无线接入点2、WIFI的无线接入点3等中的至少一个)、控制面网元、转发面网元1以及转发面网元2等。其中，无线接入点是为用户设备提供无线接入的设备，包括但不限于3G/4G、通用移动通信技术的长期演进(Long Term Evolution,LTE)、WiMAX中的基站或者Wi-Fi中的无线接入点；控制面网元用于负责移动网络中的移动性管理以及为每个PDN连接分配路径最优的转发面设备，该控制面网元可以包括移动性管理实体(Mobility Management Entity，MME)以及移动网关控制器的部分功能等；转发面网元用于为用户设备提供IP地址锚定，如P-GW、路由器、交换机等物理或虚拟的转发设备。如图2所示，用户设备可以通过同一个转发面网元或者多个转发面网元建立多个PDN连接接入到PDN网络中，其中，多个PDN连接中的每个PDN连接是用户设备基于一个IP地址分别接入到PDN网络的通信连接，多个PDN连接使得用户设备可以同时具有到达目标节点的多条路径，如基于PDN连接1的路径1、基于PDN连接2的路径2、基于PDN连接3的路径3和基于PDN连接4的路径4等，然而，对于具有多条PDN连接的用户设备来说，如何从中选择合适的PDN连接优化业务传输路径，提高业务传输质量是一个亟待解决的问题。
为了解决上述问题，本发明实施例公开了一种路径处理方法，能够为用户设备选择合适的PDN连接以优化业务传输路径，提高业务传输质量。以下分别进行详细说明。
请参阅图3，图3是本发明实施例公开的一种路径处理方法的流程示意图，如图3所示，该路径处理方法可以包括以下步骤：
S101、用户设备根据至少一个已有分组数据网PDN连接对应的连接参数信息，确定该至少一个已有PDN连接中是否存在满足目标连接条件的目标PDN连接。
本发明实施例中，用户设备可以在移动引起切换时，执行步骤S101至S104为用户设备正在传输的业务流选择合适的路径缩短业务报文的传输时延；也可以在用户设备发起新的业务流，也可以是用户设备移动切换之前发起的业务子流，执行步骤S101至S104为该新的业务流选择合适的路径缩短业务报文的传输时延。其中，用户设备移动引起的切换包括3G/4G等蜂窝网络中的小区切换、 Wi-Fi或WiMAX网络中的无线接入点切换等，本发明实施例不做限定。
本发明实施例中，已有PDN连接对应的连接参数信息包括该PDN连接所能满足的业务特性指标、该PDN连接对应的位置区域以及优先级中的至少一个，优先级用于指示在满足目标连接条件的PDN连接有多个时，根据该优先级从中选择目标PDN连接。
本发明实施例中，PDN连接所对应的连接参数信息是在每个PDN连接的建立过程中从控制面网元获得的，或者是从基站的广播消息获得，或者是从接入网络发现选择功能(Access Network Discovery and Selection Function，ANDSF)服务器获得。例如，在每个PDN连接的建立过程中从控制面网元获得可以包括以下步骤：用户设备向无线接入点(如3G/4G、LTE以及WiMAX中的基站或者Wi-Fi中的无线接入点)发送连接建立请求，该连接建立请求中包括用户设备当前的位置信息(如小区标识、基站标识或者定位的物理位置标识等)；无线接入点将该连接建立请求发送给控制面网元，由控制面网元接收该连接建立请求后，根据用户设备当前的位置信息指示的位置以及转发面网元的服务范围，为该用户设备选择路径最优以及满足该连接待传输的业务特性条件的转发面网元，并确定该连接的位置区域信息(该位置区域信息指示的位置范围包括用户设备当前的位置信息指示的位置)；控制面网元或者转发面设备可以为该连接分配一个锚定在该转发面设备上的PDN连接地址；控制面网元向无线接入点发送连接建立响应消息，该连接建立响应消息就包括了该连接以IP为索引的连接参数信息，如位置区域信息、满足该连接待传输的业务特性条件的业务特性指标或者优先级中的任一或多个等。
本发明实施例中，PDN连接对应的连接参数信息可以以一个关系表的形式存储在用户设备中，也可以以其他方式，如哈希算法的形式实现PDN连接与位置区域信息的对应。其中，表1为本发明实施例公开的一种用户设备确定的多PDN连接所对应的连接参数信息的关系表，如表1所示，该关系表中以各PDN连接的IP地址作为索引，该IP地址为创建PDN连接时所分配的或者接入网络所使用的逻辑地址，每个PDN连接以IP地址作为索引，对应存储了每个PDN连接的位置区域，该位置区域可以通过小区标识列表、物理位置范围、区域标识列表、路由标识列表、转发标识列表或者基站标识列表等来表示PDN连接所适用 的区域；每个PDN连接所能满足的业务特性指标，如时延、丢包率等，以及每个PDN连接的优先级。

S102、当存在满足目标连接条件的目标PDN连接时，用户设备通过该目标PDN连接传输业务报文。
本发明实施例中，目标连接条件可以预先配置在用户设备内，其中，目标连接条件可以包括：PDN连接对应的位置区域包含或等于用户设备当前的位置，PDN连接的业务特性指标达到业务流所需的业务特性条件以及PDN连接的优先级最高中至少一个；其中，业务特性条件可以为业务流所需的最大时延以及丢包率等QCI(QoS Class Identifier)值，该QCI值用于衡量特定的提供给业务流的包转发行为；若PDN连接的位置区域中的基站标识列表包括用户设备当前的基站标识，则说明该PDN连接的位置区域包括用户设备当前的位置；同理，PDN连接的物理位置信息指示的位置区域等于或包含用户设备通过定位获得的物理位置信息指示的位置时，也说明该PDN连接的位置区域包括用户设备当前的位置。
本发明实施例中，用户设备通过目标PDN连接所传输的业务报文，可以为用户设备在移动切换前发起的业务流的报文，也可以为用户在移动切换后发起的新的业务流的报文，本发明实施例不做限定。
S103、当不存在满足目标连接条件的目标PDN连接时，用户设备发起满足目标连接条件的目标PDN连接建立，以通过所述发起建立的目标PDN连接传输业务报文。
本发明实施例中，用户设备发起满足目标连接条件的目标PDN连接建立，包括：
用户设备通过当前基站向控制面网元发送PDN连接建立请求，所述PDN连接建立请求中包括用户设备当前的位置和/或业务特性条件；由控制面网元根据用户设备当前的位置和/或业务特性条件为用户设备选择转发面网元，由转发面网元或控制面网元为该PDN连接分配IP地址；相应地，用户设备可以接收控制面网元通过基站返回的PDN连接建立响应消息，该PDN连接建立响应消息中包括该PDN连接的IP地址，或者还可以包括该PDN连接对应的位置区域、业务特性指标和优先级中的至少一个。
可见，图3所示的路径处理方法中，用户设备根据至少一个已有分组数据网PDN连接对应的连接参数信息，确定该至少一个已有PDN连接中是否存在满足目标连接条件的目标PDN连接，当存在满足目标连接条件的目标PDN连接时，该用户设备可以通过目标PDN连接传输业务报文，当不存在满足目标连接条件的目标PDN连接时，可以发起满足目标连接条件的目标PDN连接建立，以通过该发起建立的目标PDN连接传输业务报文，可见，本发明实施例在传输业务报文时可以通过满足目标连接条件的目标PDN连接来传输，从而可以缩短业务传输的时延，提高业务传输质量等。
例如，用户设备移动切换后所维护的多个PDN连接如图2所示，切换前用户设备的业务流是通过图2中的PDN连接2进行业务报文传输的，切换后用户设备可以利用本发明实施例所述的路径处理方法为该业务流确定PDN连接3进行业务传输，由于PDN连接3可以直接通过转发面设备3与PDN网络连接，从而缩短了业务流的业务传输时延；当用户设备发起新的业务流时，则满足目标连接条件中位置区域等于或包含用户设备当前的位置的PDN连接有PDN连接3和PDN连接4，同时PDN连接3和PDN连接4中满足目标连接条件中业务特性指标达到该新的业务流所需的业务特性条件或者优先级较高的PDN连接有PDN连接4，则用户设备可以通过PDN连接4为该新的业务流进行业务报文的传输，从而达到该新的业务流所需的业务传输质量，如传输时延、丢包率等；可选的，若PDN连接3和PDN连接4中不存在业务特性指标达到该新的业务流所需的业务特性条件的PDN连接时，用户设备可以通过向控制面网元发送连接建立请求，建立满足目标连接条件的目标PDN连接，通过该建立的目标PDN连接传输业务报文，从而达到该新的业务流所需的业务传输质量，如传输时延、丢包率 等。

本发明实施例中，连接参数信息可以包括位置区域、业务特性指标和优先级中的至少一个；其中，优先级是被选择作为目标PDN连接的PDN连接的优先级。存在满足目标连接条件的目标PDN连接满足以下条件中的一个或多个：目标PDN连接对应的位置区域等于或包含路径处理装置所在的用户设备当前的位置；目标PDN连接对应的业务特性指标满足业务流所需的业务特性条件；以及目标PDN连接的优先级最高。
本发明实施例中，至少一个已有分组数据网PDN连接所对应的连接参数信息是在每个PDN连接的建立过程中从控制面网元获得的，或者是从无线接入点的广播消息获得，或者是由路径处理装置所在的用户设备从接入网络发现选择功能ANDSF服务器获得。
