Description

业务数据流发送方法及装置 技术领域
本申请涉及业务数据处理技术领域,尤其涉及一种业务数据流发送方法及装置。
背景技术
演进分组系统(英文:Evolved Packet System,简称:EPS)包括演进分组核心网(英文:Evolved Packet Core,简称EPC)、演进基站(英文:evolved Node B,简称:eNB)和用户设备(英文:User Equipment,简称:UE)。其中,EPC包括移动性管理实体(英文:Mobility Management Entity,简称:MME)、服务网关(英文:Service Gateway,S-GW)及分组数据网络网关(英文:Packet Data Network Gateway,简称:PDN-W)等。
在EPS的一个典型通信场景中,UE通过PDN连接接入PDN中,其中,PDN连接作为UE与PDN之间的IP连接,包括从UE开始到PDN-W之间的一个或多个承载。在该通信场景中,每个上行或下行业务数据流都需要匹配到一个对应的承载上,之后在此承载上传输,其中,上述的业务数据流一般是采用五元组描述的网络间互联协议(英文:Internet Protocol,简称:IP)分组数据。
为了将业务数据流匹配到相应的承载上,在EPS中通常采用数据流模板(英文:Traffic Flow Template,简称:TFT)描述业务数据流和承载的对应关系,业务数据流和与其对应的承载的映射关系通过TFT中的过滤规则进行匹配。
上述业务数据流与承载匹配的方法,通过将业务数据流的IP描述信息与业务服务器的IP地址匹配的方式确定业务数据流的发送承载。然而随着移动互联网的发展,第三方业务提供商的数据中心(英文:Data Center,简称:DC)在移动网络中的位置逐渐下移并分布式部署于移动网络的各个位置,分布部署的DC同样可以通过分布式部署的PDN-W就近为UE提供业务服务。
在这种情况下,若仍以现有的TFT负载匹配模式,可能会出现无法加载所有可能业务服务器IP地址或对加载的所有可能的服务器IP地址分别进行匹配过程过于复杂,使得业务数据流发送效率低等问题。
发明内容
本申请提供了一种业务数据流发送方法及装置,该方法以较为简便的方式确定业务数据流的发送管道,提高业务数据流的发送效率。
第一方面,本申请提供了一种业务数据流发送方法,该方法包括:
用户设备UE中的数据发送过滤器接收待发送业务数据流;
所述数据发送过滤器获取与所述待发送业务数据流对应的业务服务域名信息;

采用本实现方式:UE获取待发送业务数据流的业务服务域名信息,并根据业务服务域名信息直接匹配出相应的数据发送管道,此方式下,UE无需根据待发送业务数据流的IP描述信息与TFT过滤器的一一加载比较确定管道,实现过程比较简单,尤其,在业务服务器IP地址数量比较多、服务器IP地址经常发生变化的场景下,利用本发明实施例的方法确定待发送业务数据流的发送管道时,无需加载数量众多的服务器IP地址及相应的承载,因此也就不会出现业务服务器IP地址加载不成功,无法确定数据发送管道等问题,可见,本发明实施例方法以较为简便的方式确定业务数据流的发送管道,且能适应各类数据发送场景,提高业务数据流的发送效率。
本实现方式不仅适用于UE访问采用IP方式描述的业务服务,而且适用于UE访问采用域名信息描述的业务服务,其中,采用IP方式描述的业务服务一般是指采用五元组(包括:源IP地址、源端口、目的IP地址、目的端口及IP协议号)描述的业务服务,采用域名信息描述的业务服务一般是指采用业务服务的完全合格域名(英文:Fully Qualified Domain Name,简称:FQDN)、统一资源定位符(英文:Universal Resource Locator,简称:URL)或者应用程序标识(英文:Application Identification,简称:APP ID)信息描述的业务服务,具体的,采用APP ID信息描述业务服务时,在APP ID信息中包括该APP运行的操作系统ID和APP在该操作系统内的ID,可选的,APP ID信息中还包括APP运行的操作系统的版本号或APP的版本号。

具体的,UE中的数据发送过滤器从UE的应用层或操作系统接收待发送业务数据流,待发送业务数据流通常由五元组(源地址、目的地址、源端口号、目的端口号以及IP协议号)描述,而UE所访问的业务服务除采用IP地址描述方式外,较为常见还有域名、URL、APP ID信息等描述方式,为了快速为业务数据流分配数据发送管道,本实现方式利用业务数据流通常采用五元组描述的特点,根据业务数据流的IP描述信息,从业务数据流的IP描述信息与业务服务域名信息的对应规则中查询相应的业务服务域名信息,之后利用查询出的域名信息匹配数据发送通道,实现过程简便,而且更加适用于采用域名、URL、APP ID信息等方式描述的业务服务。

进一步,若数据发送过滤器利用待发送业务数据流对应的业务服务域名信息未查询到相应的数据发送管道或者数据发送过滤器查询到的数据发送管道所对应的规则超出预设有效时间,则UE可以根据待发送业务数据流对应的业务服务域名信息,从上述网络实体中查询待发送业务数据流对应的数据发送管道。
可选的,所述数据发送管道包括:分组数据网络PDN连接、承载或发送业务流数据采用的无线接入技术(英文:Radio Access Technology,简称:RAT)。

尤其对于为业务数据流分配RAT而言,由于不同的RAT具有不同的空口特性,如不同的RAT具有不同的服务质量(英文:Quality of Service,简称:QoS)、最大带宽以及覆盖面积等,因此不同的RAT所适合传输的业务数据流也不同,利用本方式可以实现通过简便快捷的方式为不同的业务数据流分配不同的RAT,以满足业务数据流对不同传输空口特性的需求。

具体实施方式
UE的内部系统架构一般包括应用层、操作系统及数据传输层。当应用层生成业务数据流后,业务数据流通过应用层或操作系统传输到数据传输层,数据传输层为业务数据流匹配数据管道。业务数据流通过匹配的数据管道进行发送。
基于上述UE的系统架构,本申请提供了一种业务数据流的发送方法。该方法主要应用于第三代合作伙伴计划(英文:3rd Generation Partnership Project,简称:3GPP)定义的长期演进(英文:Long Term Evolution,简称:LTE)网络以及其后续演进的蜂窝通信系统。该方法还可以应用于由蜂窝通信系统控制的接入技术中,如3GPP定义的无线局域网(英文:Wireless Local Area Networks,简称:WLAN)类的可信接入(Trusted Access)和非可信接入(Un-trusted Access),又例如LTE和WLAN融合接入的LWA接入技术。
另外,本申请中UE可以是具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,简称UE),移动台(Mobile station,简称MS),终端(terminal),终端设备(Terminal Equipment)等等。为方便描述,本申请中,简称为用户设备或UE。
图1是UE的一种内部系统架构示意图。如图1所示,数据发送过滤器部署在了数据传输层,数据发送过滤器用于为待发送业务数据流分配数据发送管道,如图1中的管道1、管道2……或管道6。其中,数据发送管道可以是PDN连接、承载或发送业务流数据采用的RAT。另外,数据发送过滤器还可以接收来自网络设备的数据,其中,网络设备可以为:ANDSF、eNB、MME、PDN-W、S-GW、PCRF、FD DB及SCEF中的一种或多种(图1仅标识出了ANDSF、PCRF、MME、PDN-W及S-GW)。可选的,数据发送过滤器可以是数据分发过滤器,用于将接收到的待发送业务数据流按照预定规则(如路由规则)分配到对应的发送管道。可选的,如图1所示,数据传输层中除部署数据发送过滤器外,还部署了流信息数据库和路由发送规则数据库。
图2是本申请业务数据流发送方法的一个实施例的流程图,包括如下步骤:
步骤S11:UE中的数据发送过滤器接收来自UE的应用层或操作系统的待发送业务数据流。
步骤S12:数据发送过滤器根据待发送业务数据流的IP描述信息,获取业务服务域名信息。
UE在步骤S11中接收到的待发送业务数据流通常是采用IP描述信息进行描述,具体的,IP描述信息可以是五元组信息(包括源IP地址、源端口、目的IP地址、目的端口及IP协议号)。
数据分发过滤器根据业务数据流的IP描述信息获取业务服务域名信息的一种实现方式可以是:在流信息数据库中预先存储业务数据流的IP描述信息与业务服务域名信息的对应规则。可选的,业务数据流的IP描述信息与业务服务域名信息的对应规则可以由UE预先配置,也可以由UE从网络设备获取。可选的,数据发送过滤器可以从ANDSF、eNB、MME、PDN-W、S-GW、PCRF、FD DB或SCEF中获取上述规则。
步骤S13:数据发送过滤器根据业务服务域名信息,获取与待发送业务数据流对应的数据发送管道。
数据发送过滤器根据业务服务域名信息,获取与待发送业务数据流对应的数据发送管道的其中一种方式是:
UE的路由发送规则数据库中预先存储着业务服务域名信息与数据发送管道的对应规则,数据发送过滤器根据业务服务域名信息从路由发送规则数据库中查询相应的数据发送管道。
可选的,业务服务域名信息与数据发送管道的对应规则可以由UE预先配置,也可以由UE从网络设备获取。可选的,数据发送过滤器可以从ANDSF、eNB、MME、PDN-W、S-GW、PCRF、FD DB或SCEF中获取上述规则。
步骤S14:数据发送过滤器根据数据发送管道发送待发送业务数据流。
本发明实施例中,当数据发送过滤器从路由发送规则数据库中查询到与待发送业务数据流对应的数据发送管道时,通过查询出的数据发送管道发送待发送业务数据流。
可选的,当数据发送过滤器从流信息数据库中未查询到与待发送业务数据流对应的业务服务域名信息,或者
当数据发送过滤器在路由发送规则数据库中未查询到与待发送业务数据流匹配的数据发送管道,或者,
当数据发送过滤器从路由发送规则库中查询到的数据发送管道匹配规则超出了有效周期时,数据发送过滤器采用UE默认的数据发送管道发送待发送业务数据流。
可选的,当路由发送规则数据库中的业务服务域名信息与数据发送管道的对应规则中存在超过有效生命周期的匹配规则时,删除超过有效生命周期的匹配规则。
需要说明的是,UE中的流信息数据库、路由发送规则数据库以及数据发送过滤器可以是合一的,也可以是分开的,可以在操作系统、应用层、数据传输层中的任何一层实现。
可选的,本申请业务数据流发送方法可以与传统方法中的以IP五元组为流描述的TFT中的过滤器(filter)和ANDSF规则等一起工作。具体的,可以本申请的业务数据流发送方法优先,也可以传统技术中的TFT匹配规则和ANDSF规则优先,也可以混合排列优先级。

图3是UE获取业务数据流的IP描述信息与业务服务域名信息对应规则的方法流程图。如图3所示,该方法的主要处理步骤包括:
步骤S121:UE的应用层将UE可能访问的业务服务的域名发送给UE的操作系统。
步骤S122:UE的操作系统根据接收到的业务服务域名,向域名系统(英文:Domain Name System,简称:DNS)服务器发送查询信息。
步骤S123:UE的操作系统接收DNS服务器返回的业务服务域名信息与业务服务器IP描述信息的对应关系。
可选的,UE的操作系统接收到的业务服务域名信息与服务器IP描述信息的对应关系包括:UE可能访问的业务服务的FQDN与业务服务器的IP描述信息之间的对应关系;和/或,UE可能访问的业务服务的URL,和/或,APP ID信息与业务服务器的IP描述信息之间的对应关系。
其中,业务服务器的IP描述信息包括业务服务器的源IP地址、目的IP地址、源端口、目的端口及IP协议号中的至少一个。
可选的,APP ID信息包括该APP运行的操作系统ID和APP在该操作系统内的 ID。可选的,APP ID信息中还包括APP运行的操作系统的版本号或APP的版本号。
步骤S124:UE的操作系统根据接收到的业务服务域名信息与业务服务器IP描述信息的对应关系,在流信息数据库中存储业务数据流的IP描述信息与业务服务域名信息的对应规则。
具体的,业务数据流的IP描述信息与业务服务域名信息的对应规则包括:业务数据流的IP描述信息与业务服务器的IP描述信息间的第一对应关系,以及业务服务器的IP描述信息与业务服务域名信息间的第二对应关系。
其中,第一对应关系包括以下一种或多种:
业务数据流的目的IP地址与业务服务器的源IP地址的对应关系;
业务数据流的目的端口与业务服务器的源端口的对应关系;
业务数据流的源IP地址与业务服务器允许访问的源地址范围的对应关系;
业务数据流的源端口与业务服务器所允许访问的源端口范围的对应关系。
例如:具体实施时,当设定业务数据流的目的IP地址与业务服务的源IP地址一致且业务数据流的目的端口与业务服务器的源端口一致时,将该匹配一致的业务服务器与业务数据流进行对应。之后可以利用该匹配一致的业务服务器确定相应的业务服务域名信息。
在利用业务服务器的IP描述信息对业务数据流进行过滤匹配时,还可以进一步限定业务数据流的源IP地址及源端口。例如:IP地址为1.1.14的业务服务器允许匹配的业务数据流的源地址范围为2.2.01~2.2.11,只有源IP地址符合相应设定范围的业务数据流才能进一步进行匹配。
业务服务的域名的域名信息包括:业务服务的域名、URL及APP ID信息。
第二对应关系包括以下一种或多种:
业务服务器的IP描述信息与相应业务服务的域名的对应关系;
业务服务器的IP描述信息与相应业务服务的URL的对应关系;
业务服务器的IP描述信息与相应业务服务的APP ID信息的对应关系。
本发明实施例中,确定业务数据流对应的业务服务器后,根据业务服务器的IP描述信息与业务服务域名信息之间的关系,确定与业务数据流对应的业务服务域名信息,具体的包括确定与业务数据流对应的业务服务的域名、URL及APP ID信息。
UE获取业务服务域名信息与数据发送管道的对应规则的处理过程包括:
(1)UE中的数据发送过滤器接收网络设备制定的业务服务域名信息与数据发送管道的对应规则,其中,制定该规则的网络实体可以是:ANDSF、eNB、MME、PDN-W、 S-GW、PCRF、FD DB及SCEF中的一种或多种。
如图1中,数据发送过滤器可以采用0a中所示的方式,即:数据发送过滤器接收用户面实体发送的业务服务域名信息与数据发送管道的对应规则。可先的,该用户面实体可以为ANDSF。
或者,数据发送过滤器采用0b中所示的方式,即:数据发送过滤器接收控制面实体发送的业务服务域名信息与数据发送管道的对应规则。可选的,该控制面实体可以为MME,其中,MME可以通过非接入层(英文:Non-Access Stratum,简称:NAS)向UE中的数据发送过滤器发送业务服务域名信息与数据发送管道的对应规则。当采用NAS向UE中的数据发送过滤器发送业务服务域名信息与数据发送管道的对应规则时,该规则可以作为对TFT的扩充,即TFT中包括的流过滤器在对业务数据流进行过滤匹配时可以突破仅利用IP信息进行匹配的局限。
MME及ANDSF发送的业务服务域名信息与数据发送管道的对应规则的原始来源可以是PCRF。
(2)数据发送过滤器将从网络设备获得的业务服务域名信息与数据发送管道的对应规则存储在路由发送规则数据库,从而为数据发送过滤器进行数据发送管道查询提供支持。
本申请中,业务服务域名信息与数据发送管道的对应规则包括:
业务服务的FQDN、URL或APP ID信息与数据发送管道的对应规则,其中,数据发送管道可以为PDN连接、承载或者发送业务流数据采用的RAT。
可选的,业务服务域名信息与数据发送管道的对应规则中,业务服务域名信息中的部分内容可以采用通配符代替,如,用‘?’代表任意一个字符,用于‘*’代表任意多个字符。
例如,FQDN的一种典型格式是:abc.alice.com,其中可以使用‘?’代表其中的一个字符,如‘?bc.alice.com’,在该域名中‘?’代表任意一个字符;另外,也可以使用‘*’代表FQDN中的用’.’隔开的字符内容,如用‘*.alice.com’表示一个FQDN,用‘*’表示的部分可以是任意多个任意字符。
进一步,URL中的部分内容也可以使用通配符表示,例如,URL的标准格式如下:
协议类型://服务器地址(必要时需加上端口号)/路径/文件名;
URL的一个具体例子可以为:https://www.alice.com/book/new.txt;
当在URL中使用通配符时,上述URL可以表示为:http?://www.alice.com/book/*.txt,其中‘?’代表任意一个字符,‘*’表示的部分可以是任意多个任意字符。
参照上述描述,APP ID信息中的内容也可以使用通配符进行标识。
按照本发明实施例方法,根据待发送业务数据流的IP描述信息确定出的业务服务域名信息通常确定域名,如为‘abc.alice.com’,而预先存储的业务服务域名信息与数据发送管道对应规则中的业务服务域名信息可能是带有通配符的,如为‘*.alice.com’,‘a?c.alice.com’,‘*bc.alice.*’,当待发送业务数据流的业务服务域名信息符合路由发送规则数据库中的带有通配符的域名信息格式匹配时,确定该带有通配符的业务服务域名信息对应的数据发送管道为待发送业务数据流的发送管道。
可选的,路由发送规则数据库中包含的每个业务服务域名信息与数据发送管道的对应关系均标识有有效生命周期,若超过有效生命周期,则相应的业务服务域名信息与数据发送管道的对应关系失效。UE可以将失效的业务服务域名信息与数据发送管道的对应关系删除。
可选的,网络设备(如PCRF、ANDSF或MME等)可以根据UE访问业务的部署位置、服务质量要求以及会话连续性要求等因素制定业务服域名信息与数据发送管道的对应规则。
如,abc1.alice.com的业务在UE就近部署的情况下,可以将abc1.alice.com配置到能够就近访问的管道(承载,PDN连接,RAT)。
abc2.alice.com的业务需要高质量服务保障的情况下,可以将abc2.alice.com配置到能提供高质量的管道(承载,PDN连接,RAT)。
abc3.alice.com的业务需要高会话连续性保障的情况下,可以将abc3.alice.com配置到能提供较高移动性(移动性锚点较高)的管道(承载,PDN连接,RAT)。
可选的,本实施例的规则也可能来自第三方的配置,如提供互联网(Internet)业务的第三方通过API接口配置规则的内容。
本申请的业务数据流发送方法,根据网络设备配置的路由发送规则,在UE中简便快捷地为待发送业务数据流分配数据发送管道,满足业务数据流发送的现实需求。

步骤S24:数据发送过滤器通过与待发送业务数据流对应的数据发送管道发送待发送业务数据流。
需要说明的是,当数据发送过滤器在路由发送规则数据库中未查询到与待发送业务数据流匹配的数据发送管道或者数据发送过滤器从路由发送规则数据库中查询到的数据发送管道的匹配规则超出了有效周期时,数据发送过滤器采用UE默认的数据发送管道发送待发送的业务数据流。
