在第五代(the 5th-Generation,5G)移动通信技术中,提出了会话管理功能(session management function,SMF)网元的服务区域的概念,即SMF网元只管理服务区域内的用户面功能(user plane function,UPF)网元。在不同的区域内,终端设备可以通过不同的UPF网元访问数据网络(Data Network,DN),管理不同UPF网元的SMF网元也可能不同。
现有技术中,在锚点SMF网元管理的第一区域内,由锚点SMF网元管理的第一锚点UPF网元执行对第一区域内的数据包的处理方法。例如,该处理方法包括计费,用量控制,服务质量控制等。

图6A、6B为根据本申请实施例中提供的一种策略管理的装置/终端设备的结构示意图。
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地描述。本申请中,“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
图1为本申请实施例提供的一种策略管理的场景示意图。如图1所示,终端设备108在移动之前位于区域1中,并在区域1中建立了一条用户面路径:终端设备108通过第二锚点用户面功能(User plane function,UPF)网元102接入第二数据网络(Data Network,DN)103。其中,第二锚点UPF网元102由锚点会话管理功能(session management function,SMF)网元101管理。
当终端设备108从区域1移动到区域2时,由于终端设备108不在锚点SMF网元101的 服务区域内,即移出了锚点SMF网元101的服务区域,所以核心网在区域2中插入了中间SMF网元104为终端设备108服务。中间SMF网元104在区域2中插入了分支点105和第一锚点UPF网元106,其中,中间SMF网元106用于管理分支点105和第一锚点UPF网元106。分支点105用于对终端设备建立的会话进行分流,使得终端设备108在区域2中建立了两条用户面路径:(1)终端设备108依次通过分支点105和第一锚点UPF网元106接入第一DN 107;(2)终端设备108依次通过分支点105和第二锚点UPF网元102接入第二DN 103。
需要说明的是,如果在区域2中具有N个(N为大于1的整数)第一DN,中间SMF网元会插入N个第一锚点UPF网元分别连接至N个第一DN。
在图1所示的场景中:第一DN 107在区域2内,第一DN 107支持的第一应用的数据包经过第一锚点UPF网元106和分支点105传输,所以对区域1内的数据包的处理方法可以由第一锚点UPF网元106和分支点105中的一个或多个执行。第二DN 103在区域1内,第二DN 103支持的第二应用的数据包经过第二锚点UPF网元102和分支点105传输,所以对区域2内的数据包的处理方法可以由第二锚点UPF网元102和分支点105中的一个或多个执行。
图1所示的场景示意图适用于5G通信系统。在5G移动网络架构中,移动网关的控制面功能和转发面功能解耦,其分离出来的控制面功能与第三代合作伙伴计划(third generation partnership project,3GPP)传统的控制网元移动性管理实体(mobility management entity,MME)等合并成统一的控制面(control plane)。UPF网元能实现服务网关(serving gateway,SGW)和分组数据网络网关(packet data network gateway,PGW)的用户面功能(SGW-U和PGW-U)。进一步的,统一的控制面网元可以分解成接入和移动性管理功能(access and mobility management function,AMF)网元和SMF网元。

需要说明的是,本系统中所涉及到的分支点105和第一锚点UPF网元106可以为一个合设的网元,或者可以作为两个独立的网元。本申请实施例对此不作限定。

下面以图1所描述的场景为例,通过一些实施例对本申请的技术方案进行详细说明。下面这几个实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例不再赘述。
图2为本申请实施例提供的一种方法,该方法可以适用于图1所描述的场景。通过该方法,可以实现区域2的网元执行对区域2内数据包的处理方法。如图2所示,该方法可以包括:
S201、第一SMF网元从第二SMF网元接收第一信息。其中,第一信息用于指示第二SMF网元管理的第一锚点UPF网元所连接的数据网络。
例如,第一SMF网元为图1中的锚点SMF网元101。第二SMF网元为图1中的中间SMF网元104。第一锚点UPF网元为图1中的第一锚点UPF网元106。第一锚点UPF网元所连接的数据网络为图1中的第一DN 107。
例如,第一信息为数据网络接入标识(DNAI,Data Network Access identifier)。第一信息用于指示中间SMF网元管理的第一锚点UPF网元所连接的第一DN的接入标识。
可选的,若中间SMF网元管理了N个(N为大于1的整数)第一锚点UPF网元,且N个第一锚点UPF网元分别连接了N个数据网络,则第一信息用于指示N个第一锚点UPF网元中各第一锚点UPF网元分别连接的N个数据网络。
S202、第一SMF网元根据第一信息,确定由第二SMF网元管理的第一网元执行的第一规则信息。其中,第一网元包括第一锚点UPF网元或分支点中的至少一项,分支点为具有分流功能的UPF网元,分支点与第一锚点UPF网元相连,第一规则信息用于指示对第一应用的数 据包的处理方法,第一应用的数据包经过第一锚点UPF网元传输。
例如,分支点为图1中的分支点105。第一网元包括图1中第一锚点UPF网元106或分支点105中的至少一项。第一应用为图1中第一DN 107支持的应用,第一应用的数据包经过第一锚点UPF网元106传输。
例如,第一规则信息可以为策略与计费控制(Policy and Charging Control,PCC)规则。
例如,第一信息为DNAI,若第一规则信息中包括了第一信息中的DNAI,则第一SMF网元确定该PCC规则对应的数据包经过第一锚点UPF和分支点传输,所以第一SMF网元根据第一信息,确定由第一锚点UPF网元或分支点中的至少一项执行该PCC规则。
需要说明的是,第一应用的数据包包括以下任一一种:第一应用的上行数据包,第一应用的下行数据包,或第一应用的上行数据包和下行数据包。
相应的,第一网元执行第一规则信息包括以下四种方式中的任一种:

S203、第一SMF网元向第二SMF网元发送第二信息。其中,第二信息包括第一规则信息。
可选的,第二信息还包括第一网元的指示信息(即第五指示信息)。此时,由第一网元的指示信息指示第一网元是分支点或第一锚点UPF网元,即由第一网元的指示信息指示执行第一规则信息的网元是分支点或第一锚点UPF网元。例如,第五指示信息可以为步骤S201中的第一信息。
可选的,第二信息不包括上述第五指示信息。此时,由第二信息中的第一规则信息指示执行第一规则信息的网元是分支点。
可选的,第一SMF网元还可以通过第二信息向第二SMF网元指示第一网元是分支点还是第一锚点UPF网元。在一种可能的实现方式中,当第二信息包括第五指示信息时,第一网元为第一锚点UPF网元;当第二信息不包括第五指示信息时,第一网元为分支点。例如,该第五指示信息可以是步骤S201中获取的DNAI。
根据本发明实施例的方法,在图1所示的场景中,当区域2内的数据包不经过区域1内的第二锚点UPF网元传输时,可以由区域2内的第一锚点UPF网元或分支点中至少一个网元执行对区域2内的数据包的处理方法。通过对区域2中的数据包进行计费、用量控制、服务质量控制等处理,增强了核心网对用户数据的管理能力。
可选的,对于步骤S202中第一SMF网元确定的第一网元执行第一规则信息的四种方式,第二信息还包括如下内容:
在实现方式(1)中,分支点执行对第一应用的下行数据包的处理方法,如果第一应用的下行数据包属于需要通过深度报文检测的业务数据流SDF(Service Data Flow),则分支点识别第一应用的下行数据包时可能会依赖该下行数据包的前一个下行数据包。相应的,第一规则信息用于指示分支点对第一应用的数据包的处理方法,第二信息中还包括第一标识信息和第三指示信息。其中,第一标识信息用于标识第一应用的数据包,第三指示信息用于指示第二SMF网元(例如,中间SMF网元)请求第一锚点UPF网元发送第一应用的下行数据包时携带第一标识信息。因此,即便分支点在PDU会话建立后才插入,分支点也能够根据下行数 据包中携带的第一标识信息获知该下行数据包为第一应用的下行数据包,从而正常执行对第一应用的下行数据包的处理。
例如,第一标识信息包括SDF标签。本实施例不限定SDF标签的格式,例如,SDF标签可以是(GPRS tunneling protocol,GTP)GPRS隧道协议(GPRS:general packet radio service,通用分组无线业务)头中一个字段,或者在GTP头和(Internet Protocol,IP)互联网协议头间增加的一个用于携带SDF标签的封装,或者其他格式。
根据实现方式(1)的方法,当第一应用的下行数据包属于需要通过深度报文检测的SDF时,第一锚点UPF网元发送第一应用的下行数据包时携带第一标识信息,分支点根据第一标识信息可以识别出第一应用的下行数据包,从而可以执行对第一应用的下行数据包的处理方法。
在实现方式(2)中,第一应用的下行数据包依次经过第一锚点UPF网元和分支点传输,其中分支点可能会在控制会话聚合最大比特速率(aggregate maximum bit rate,AMBR)时丢包。则第二信息还包括第一指示信息,第一指示信息用于指示第二SMF网元(例如,中间SMF网元)请求分支点上报丢包信息,丢包信息包括第一应用的下行数据包的丢弃数量。例如,第一应用的下行数据包的丢弃数量可以为字节数或者包数。因此,即便分支点可能会丢包,第一SMF网元(例如,锚点SMF网元)也能够根据从第一锚点UPF网元接收的第一应用的下行数据包数量和分支点上报的丢包信息,可以确定第一应用的下行数据包的实际数量。从而保证了第一锚点UPF网元执行对第一应用的下行数据包的处理方法时的准确性。
例如,第一SMF网元(例如,锚点SMF网元)通过第二SMF网元(例如,中间SMF网元)从分支点接收上述丢包信息,第一SMF网元通过第二SMF网元(例如,中间SMF网元)从第一锚点UPF网元接收第一应用的下行数据包数量,然后第一SMF网元从第一应用的下行数据包数量中减去丢包信息中的丢弃数量,确定出第一应用的下行数据包的实际数量。
根据实现方式(2)的方法,当第一锚点UPF网元执行对第一应用的下行数据包的处理方法时,第一SMF网元根据从第一锚点UPF网元接收的第一应用的下行数据包数量和从分支点接收的丢包信息,可以确定第一应用的下行数据包的实际数量。从而保证了第一锚点UPF网元执行对第一应用的下行数据包的处理方法时的准确性。
在实现方式(2)中,第二信息中还包括第一标识信息和第三指示信息。其中,第一标识信息用于标识第一应用的数据包,第三指示信息用于指示第二SMF网元(例如,中间SMF网元)请求第一锚点UPF网元发送第一应用的下行数据包时携带第一标识信息。当第一应用的下行数据包属于需要通过深度报文检测的SDF时,第一锚点UPF网元发送第一应用的下行数据包时携带第一标识信息,分支点根据第一标识信息可以识别出第一应用的下行数据包,从而可以统计丢弃的第一应用的数据包。
在实现方式(3)中,分支点执行对第一应用的上行数据包的处理方法时,如实现方式(1)中所描述的,如果第一应用的上行数据包属于需要通过深度报文检测的SDF,则第二信息中还包括第一标识信息和第三指示信息。第二SMF网元(例如,中间SMF网元)根据第三指示信息请求第一锚点UPF网元发送第一应用的下行数据包时携带第一标识信息。终端设备接收第一应用的下行数据包时会接收第一标识信息,并且终端设备向分支点发送第一应用的上行数据包时携带该第一标识信息。由此,分支点可以识别第一应用的上行数据包。
在实现方式(3)中,第一锚点UPF网元执行对第一应用的下行数据包的处理方法时,如实现方式(2)中所描述的,第二信息还包括第一指示信息,第一指示信息用于指示第二SMF网元(例如,中间SMF网元)请求分支点上报丢包信息。因此,即便分支点可能会丢包,第 一SMF网元(例如,锚点SMF网元)也能够根据从第一锚点UPF网元接收的第一应用的下行数据包数量和分支点上报的丢包信息,可以确定第一应用的下行数据包的实际数量。从而保证了第一锚点UPF网元执行对第一应用的下行数据包的处理方法时的准确性。。
根据实现方式(3)的方法,如果第一应用的上行数据包属于需要通过深度报文检测的SDF,分支点根据第一标识信息可以识别出第一应用的上行数据包,从而可以执行对第一应用的上行数据包的处理方法。当第一锚点UPF网元执行对第一应用的下行数据包的处理方法时,根据从第一锚点UPF网元接收的第一应用的下行数据包数量和从分支点接收的丢包信息,可以确定第一应用的下行数据包的实际数量。从而保证了第一锚点UPF网元执行对第一应用的下行数据包的处理方法时的准确性。
在实现方式(4)中,分支点执行对第一应用的上行数据包和下行数据包的处理方法时,如实现方式(1)和实现方式(3)中所描述的,如果第一应用的上行数据包和下行数据包属于需要通过深度报文检测的SDF,则第二信息中还包括第一标识信息和第三指示信息。
根据实现方式(4)的方法,如果第一应用的上行数据包和下行数据包属于需要通过深度报文检测的SDF,分支点根据第一标识信息可以识别出第一应用的上行数据包和下行数据包,从而可以执行对第一应用的上行数据包和下行数据包的处理方法。
上述实现方式(1)、(2)和(4)的实现过程可以分别结合图3、图4和图5进一步描述。

例如,第一锚点UPF网元和分支点可以合设为一个网元,也可以为两个不同的网元。当第一锚点UPF网元和分支点为两个不同的网元时,分支点分别与第一锚点UPF网元和第二锚点UPF网元相连。
S302、第二SMF网元与分支点进行N4会话建立。
例如,第二SMF网元向分支点发送N4会话建立请求,分支点向第二SMF网元发送N4会话建立响应。从而创建分支点到第一锚点UPF网元间的用户面隧道以及分支点到第二锚点UPF网元间的用户面隧道。
S303、第二SMF网元与第一锚点UPF网元进行N4会话建立。
例如,第一锚点UPF网元为图1中的第一锚点UPF网元106。

例如,第一规则信息可以为PCC规则。
例如,第一信息为DNAI,若第一规则信息中包括了第一信息中的DNAI,则第一SMF网元确定该PCC规则对应的数据包经过第一锚点UPF和分支点传输,所以第一SMF网元根据第一信息,确定第一锚点UPF网元执行对第一应用的上行数据包的处理方法,分支点执行对第一应用的下行数据包的处理方法。
S307、第一SMF网元向第二SMF网元发送第二信息。相应的,第二SMF网元从第一SMF网元接收第二信息。其中,第二信息包括第一规则信息。
例如,第一SMF网元通过会话更新响应消息向第二SMF网元发送第二信息。
需要说明的是,本实施例对携带第二信息的消息格式不做限定。例如,该消息格式可以是PCC规则格式,或者是根据PCC规则生成基于N4接口的消息格式(例如数据包检测规则,Packet Detection Rule,PDR),或者是其他格式。
可选的,第二信息还包括以下信息中的一种或多种:
第一种信息:数据包标识信息,如SDF标签或五元组或应用标识等;
第二种信息:操作信息,如计费、用量监控或QoS控制等;

第四种信息:若第二SMF网元管理了N个(N为大于1的整数)第一锚点UPF网元,且N个第一锚点UPF网元分别连接了N个数据网络,则第一信息用于指示N个第一锚点UPF网元分别连接的N个数据网络。由于每个第一锚点UPF网元只能对经过该第一锚点UPF网元传输的数据包进行处理,所以为了将数据包的处理规则发送给对应的第一锚点UPF,则当第一规则信息用于指示第一锚点UPF网元执行对第一应用的上行数据包的处理方法时,第一规则信息中包括对经过各个第一锚点UPF网元的数据包的处理规则和各个第一锚点UPF网元对应的DNAI。
可选的,由于第一规则信息用于指示分支点执行对第一应用的下行数据包的处理方法,第一规则信息中可以不包括该第一规则信息对应的DNAI。
