The technical solutions of the present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with the embodiments.
在一些实施例中,参见图1,图中示出了一种数据传输的方法,具体包括以下步骤。In some embodiments, referring to FIG. 1, a method of data transmission is illustrated, including the following steps.
步骤101、PGW(PDN网关)接收终端关闭分组交换数据的信息,然后进入步骤102; Step 101, the PGW (PDN gateway) receives the information that the terminal closes the packet exchange data, and then proceeds to step 102;
可选地,上述终端关闭分组交换数据的信息表示UE关闭PS数据业务。Optionally, the information that the terminal closes the packet switched data indicates that the UE closes the PS data service.
可选方式一:PGW接收PCRF(策略和计费规则功能)发送的关闭数据信息。该关闭数据信息由UE向应用服务器发送,再由应用服务器向PCRF发送。Option 1: The PGW receives the closed data information sent by the PCRF (Policy and Charging Rules function). The closed data information is sent by the UE to the application server, and then sent by the application server to the PCRF.
可选方式二:PGW接收SGW(服务网关)发送的关闭数据信息。该关闭PS数据信息由UE向MME(移动性管理实体)发送,再由MME消息向SGW发送。Option 2: The PGW receives the closed data information sent by the SGW (Serving Gateway). The closed PS data information is transmitted by the UE to the MME (Mobility Management Entity), and then transmitted by the MME message to the SGW.
可选地,终端关闭分组交换数据的信息包括:UE关闭分组交换数据的指示信息和指定应用的相关信息,在UE关闭分组交换数据业务时网络可继续向UE传输指定应用的数据。其中,指定应用的相关信息可以是应用标识,也可以是IP filter(IP包过滤器)。Optionally, the information that the terminal turns off the packet-switched data includes: the UE turns off the indication information of the packet-switched data and the related information of the specified application, and the network may continue to transmit the data of the specified application to the UE when the UE closes the packet-switched data service. The related information of the specified application may be an application identifier or an IP filter (IP packet filter).
当终端关闭数据业务时,为了避免出现由于终端不向网络通知已关闭分组交换数据业务,存在过度计费或掉话的问题,终端可以向网络通知分组交换数据业务已关闭的事件。为了解决掉话的问题,运营商可以定义指定应用(例如PS Data OFF Exempt services),即使终端关闭分组交换数据业务,网络也正常转发指定应用(例如PS Data OFF Exempt services)的数据。指定应用(例如PS Data OFF Exempt services)的示例可以为IMS语音业务,IMS短消息业务,IMS视频呼叫,基于PS域的设备管理等,当然也并不限于此。When the terminal closes the data service, in order to avoid the problem that the terminal does not notify the network that the packet switched data service is closed, there is a problem of excessive charging or dropped calls, the terminal may notify the network of the event that the packet switched data service is closed. In order to solve the problem of dropped calls, the operator can define a specified application (for example, PS Data OFF Exempt services), and the network normally forwards data of a specified application (for example, PS Data OFF Exempt services) even if the terminal closes the packet switched data service. Examples of the designated application (for example, PS Data OFF Exempt services) may be IMS voice service, IMS short message service, IMS video call, PS domain-based device management, etc., of course, without being limited thereto.
步骤102、PGW根据终端关闭分组交换数据的信息传输数据。Step 102: The PGW transmits data according to information that the terminal closes the packet exchange data.
例如,如果UE关闭数据,当PGW接收到数据包时,PGW判断数据包
是否属于指定应用;如果数据包不属于指定应用,则PGW丢弃数据包,否则PGW正常转发数据包。For example, if the UE turns off the data, when the PGW receives the data packet, the PGW judges the data packet.
Whether it belongs to the specified application; if the data packet does not belong to the specified application, the PGW drops the data packet, otherwise the PGW normally forwards the data packet.
在本实施例中,PGW接收终端关闭分组交换数据的信息,PGW根据终端关闭分组交换数据的信息传输数据,当终端关闭分组交换数据业务时,为了避免出现由于终端不向网络通知已关闭分组交换数据业务,存在过度计费或掉话的问题上述问题,终端可以向网络通知分组交换数据业务已关闭的事件,运营商可以定义指定应用(例如定义为PS Data OFF Exempt services),即使终端关闭数据业务,网络也正常转发指定应用(例如PS Data OFF Exempt services)的数据。In this embodiment, the PGW receiving terminal closes the information of the packet-switched data, and the PGW transmits the data according to the information of the terminal closing the packet-switched data. When the terminal closes the packet-switched data service, in order to avoid the occurrence of the closed packet switching because the terminal does not notify the network. Data service, there is a problem of over-billing or dropped calls. The above problem, the terminal can notify the network of the event that the packet-switched data service is closed, and the operator can define a specified application (for example, defined as PS Data OFF Exempt services) even if the terminal closes the data. Business, the network also normally forwards data for specified applications (such as PS Data OFF Exempt services).
在一些实施例中,UE关闭PS数据时,其通过应用服务器向PGW发送PS DATA OFF Exempt service的信息的过程,具体过程如下:In some embodiments, when the UE closes the PS data, it sends the PS DATA OFF Exempt service information to the PGW through the application server, as follows:
应用服务器向PCRF发送第一请求消息,消息中携带有提示信息,该提示信息表明终端关闭PS数据时可继续传输该指定应用的数据,即该指定应用可以定义为PS DATA OFF Exempt service。PCRF向PGW发送第二请求消息,消息中携带与应用相关的信息(如应用标识或IP流过滤器)和PS DATA OFF Exempt service的提示信息。当UE决定关闭PS数据业务时,UE向应用服务器发送第三请求消息,消息中携带关闭PS数据的提示信息。需要说明的是,当UE决定打开PS数据业务时,过程同上,区别在于上述请求消息中只携带打开PS数据的信息。The application server sends a first request message to the PCRF, where the message carries the prompt information, and the prompt information indicates that the data of the specified application can be continuously transmitted when the terminal closes the PS data, that is, the designated application can be defined as a PS DATA OFF Exempt service. The PCRF sends a second request message to the PGW, and the message carries information related to the application (such as an application identifier or an IP stream filter) and a prompt message of the PS DATA OFF Exempt service. When the UE decides to disable the PS data service, the UE sends a third request message to the application server, where the message carries the prompt information for closing the PS data. It should be noted that when the UE decides to open the PS data service, the process is the same as above, except that the request message only carries the information of opening the PS data.
参见图2,图中示出了一种数据传输的方法,具体包括以下步骤。Referring to FIG. 2, a method for data transmission is shown, which specifically includes the following steps.
步骤200、终端向应用服务器发送第三请求消息,消息中携带终端关闭PS数据的提示信息。Step 200: The terminal sends a third request message to the application server, where the message carries the prompt information that the terminal closes the PS data.

In addition, the message may also carry related information of the service flow, such as an app ID or an IP filter.
在终端关闭PS数据业务时,网络可继续向终端传输上述PS Data OFF Exempt services的数据。When the terminal closes the PS data service, the network can continue to transmit the data of the above PS Data OFF Exempt services to the terminal.
步骤202、PCRF向PGW发送第二请求消息,消息中携带应用的相关信息和PS data offexempt service信息,其中应用的相关信息可以是app ID(应
用标识)或IP filter(IP包过滤器)。Step 202: The PCRF sends a second request message to the PGW, where the message carries related information of the application and PS data offexempt service information, where the related information of the application may be an app ID (should be
Use the identifier) or IP filter (IP packet filter).
步骤203、PGW向PCRF发送第二确认消息。Step 203: The PGW sends a second acknowledgement message to the PCRF.
步骤204、PCRF向应用服务器返回第一确认消息。Step 204: The PCRF returns a first confirmation message to the application server.
步骤205、应用服务器向UE返回第三确认消息。Step 205: The application server returns a third confirmation message to the UE.
在该实施例中,当UE重新打开PS数据业务时,上述过程中的步骤200至202中只需要携带打开PS数据的提示信息,具体流程在此不再敷述。In this embodiment, when the UE re-opens the PS data service, the steps 200 to 202 in the foregoing process only need to carry the prompt information for opening the PS data, and the specific process is not described here.

UE向网络发送关闭PS数据业务的提示信息:UE通过NAS(Non-Access-Stratum)消息向MME发送PS DATA OFF Exempt service的信息(如app ID或IP filter)和关闭PS数据的提示,MME通过GTP-C(GPRS隧道协议控制面)消息将上述内容发送给SGW,SGW通过GTP-C消息将上述内容发送给PGW。需要说明的是,当UE决定打开PS数据业务时,过程同上,区别在于上述请求消息中只携带打开PS数据的信息。The UE sends a prompt message for closing the PS data service to the network: the UE sends a PS DATA OFF Exempt service information (such as an app ID or an IP filter) to the MME through a NAS (Non-Access-Stratum) message, and a prompt to close the PS data, and the MME passes the The GTP-C (GPRS Tunneling Protocol Control Plane) message sends the above content to the SGW, and the SGW sends the content to the PGW through the GTP-C message. It should be noted that when the UE decides to open the PS data service, the process is the same as above, except that the request message only carries the information of opening the PS data.
PGW路由数据的行为如下:PGW接收到数据,PGW判断该数据所属的UE是否已关闭PS数据业务。如果该UE已关闭PS数据业务,则PGW判断该数据是否属于PS DATA OFF Exempt service,如果属于,则PGW正常转发该数据,否则PGW丢弃该数据。如果该UE未关闭PS数据业务,则PGW正常转发数据。The behavior of the PGW routing data is as follows: The PGW receives the data, and the PGW determines whether the UE to which the data belongs has closed the PS data service. If the UE has turned off the PS data service, the PGW determines whether the data belongs to the PS DATA OFF Exempt service, and if so, the PGW normally forwards the data, otherwise the PGW discards the data. If the UE does not turn off the PS data service, the PGW normally forwards the data.
