一种实现业务优化的方法及***Method and system for realizing business optimization 技术领域Technical field
本发明涉及通信领域，尤其涉及一种实现业务优化的方法及***。The present invention relates to the field of communications, and in particular, to a method and system for implementing service optimization.
背景技术Background technique
随着移动互联网的高速发展，以及智能手机和智能终端的快速普及，视频业务在移动宽带网络中越来越流行。随着视频业务流量风暴的到来，运营商将面临不断增加运营带宽的需求，从而增加运营成本。从技术上看，移动宽带网络与固定宽带网络不同，无线接入网络带宽稳定性差，存在频谱资源瓶颈。当多用户同时访问视频业务时，大流量会吞噬空口资源导致网络拥塞，用户体验面临更大的挑战。如何对大流量数据业务进行传输优化，提高网络资源利用率，缓解数据流量风暴对运营商网络的冲击，并实现业务增值以及为用户提供差异化的多媒体应用体验正为移动视频业务发展过程需要解决的关键问题。因此，如何解决移动宽带大数据业务带来的问题是目前移动互联网中的重要研发方向。With the rapid development of mobile Internet and the rapid spread of smart phones and smart terminals, video services are becoming more and more popular in mobile broadband networks. With the arrival of video traffic storms, operators will face increasing demands for operational bandwidth, which will increase operating costs. From a technical point of view, the mobile broadband network is different from the fixed broadband network. The bandwidth stability of the wireless access network is poor, and there is a spectrum resource bottleneck. When multiple users access the video service at the same time, large traffic will consume the air interface resources and cause network congestion, and the user experience faces greater challenges. How to optimize the transmission of large-traffic data services, improve the utilization of network resources, mitigate the impact of data traffic storms on carrier networks, and realize value-added services and provide differentiated multimedia application experiences for users. The key issue. Therefore, how to solve the problem brought by the mobile broadband big data service is an important research and development direction in the mobile Internet.
基于无线网络大数据业务传输过程遇到的问题分析，业界提出多种解决方案。典型的解决方案例如是下一代移动通信网络联盟(NGMN，Next Generation Mobile Networks)提出的移动内容传送优化(MCDO,Mobile Content Delivery Optimization)架构以及华为公司的源地址认证提高(SAVi，Source Address Validation improvements)方案。下一代移动通信网络联盟提出了MCDO架构。MCDO架构在无线网络侧部署本地缓存(Local Cache)，在核心网侧部署核心缓存(Core Cache)，通过本地缓存和核心缓存的协同配合，达到提高业务接入速率以及节省传输资源的目的。演进节点B(eNB，evolved Node B)直接把业务透传给本地缓存以进行处理。本地缓存通过包检测对业务进行盲处理。 Based on the analysis of problems encountered in the transmission process of wireless data big data services, the industry proposes a variety of solutions. Typical solutions are, for example, the Mobile Content Delivery Optimization (MCDO) architecture proposed by Next Generation Mobile Networks (NGMN) and Huawei's Source Address Validation improvements (SAVi, Source Address Validation improvements). )Program. The Next Generation Mobile Communications Network Alliance proposes the MCDO architecture. The MCDO architecture deploys a local cache on the wireless network side and a core cache on the core network side. The collaboration between the local cache and the core cache improves the service access rate and saves transmission resources. The evolved Node B (eNB) directly transmits the service to the local cache for processing. The local cache blindly processes the service through packet inspection.
华为公司提出了SAVi方案。在SAVi方案中，演进节点B直接转发所有数据请求给SAVi平台(SAVi Platform)。SAVi平台通过包检测对业务进行盲处理。Huawei has proposed the SAVi solution. In the SAVi scheme, the evolved Node B forwards all data requests directly to the SAVi platform (SAVi Platform). The SAVi platform blindly processes the service through packet inspection.
综上，现有技术中的无线网络业务优化的常用架构与流程为：将逻辑单元-服务优化代理(服务优化代理)部署在运营商的无线网络中。服务优化代理主要负责业务优化处理功能，例如内容缓存，视频转码，网页加速等。In summary, the common architecture and process of wireless network service optimization in the prior art is: deploying a logical unit-service optimization agent (service optimization agent) in the operator's wireless network. The Service Optimization Agent is primarily responsible for business optimization processing functions such as content caching, video transcoding, web page acceleration, and more.
目前，服务优化代理架构实现业务优化的流程如下为：演进节点B需要转发所有业务请求给服务优化代理，服务优化代理在完成包解析处理后，确定对哪些数据包进行处理以及对哪些数据包进行透传。常见的数据包解析技术为深度包检测(DPI，Deep Packet Inspection)。通常，DPI技术对服务器性能要求较高。使用DPI技术不仅增加了服务优化代理的实现复杂度，同时还会造成一定程度的业务时延。At present, the service optimization agent architecture implements the service optimization process as follows: the evolved node B needs to forward all service requests to the service optimization agent, and after completing the packet parsing process, the service optimization agent determines which data packets are processed and which data packets are processed. Penetrate. A common packet parsing technique is Deep Packet Inspection (DPI). In general, DPI technology requires high server performance. The use of DPI technology not only increases the implementation complexity of the service optimization agent, but also causes a certain degree of business delay.
因此，现有技术中需要一种能够在通信网络中提高业务优化效率的方法及***，从而克服上述缺陷。Therefore, there is a need in the prior art for a method and system that can improve the efficiency of service optimization in a communication network, thereby overcoming the above drawbacks.

The eNB connects to the service optimization agent through a link. The service optimization agent is connected to the service agent through a link and is connected to the service gateway or packet data network gateway through a link. The service agent is connected to the service gateway or packet data network gateway through a link and is connected to the service provider server through a link. The service optimization rules are dynamically set and installed at the eNB or the service optimization agent so that the service optimization agent can avoid detecting all data flows through the eNB, thereby reducing the complexity of the service optimization agent and reducing the service delay.
图2示出了根据本发明实施例的设定业务优化规则的示意图。图2的***200包括：服务优化代理201、eNB 202、运营与业务支撑***(OSS/BSS，Operation support system/Business support system)203、策略和计费功能 (PCRF，Policy and Charging Rules Function)204、服务提供商服务器205、服务网关或分组数据网网关206以及服务代理207。通常，可由OSS/BSS、PCRF或者服务代理等节点来完成业务优化规则的设定。如图2所示，服务优化代理可从运营与业务支撑***OSS/BSS、策略和计费功能PCRF或者服务代理等获取业务优化规则，所述业务优化规则至少包括：服务优化代理提供服务的终端的终端类型，或者服务优化代理提供的业务的业务类型。除此之外，服务优化代理可以从OSS/BSS、PCRF或者服务代理处获得业务优化规则的各种参数信息。所述参数信息包括但不限于：公共陆地移动网络(PLMN，Public Land Mobile Network)标识、接入点名称(APN，Access Point Name)、终端类型、业务类型、终端标识、服务质量等级标识(QCI，QoS Class Identifier)、接受业务优化的业务或者接受业务优化的业务服务质量QoS等。服务优化代理可根据从OSS/BSS、PCRF或者服务代理处获得的各种参数信息来进行业务优化规则的设置。FIG. 2 shows a schematic diagram of setting a service optimization rule according to an embodiment of the present invention. The system 200 of FIG. 2 includes: a service optimization agent 201, an eNB 202, an operation support system/business support system (OSS/BSS), a policy and a charging function. (PCRF, Policy and Charging Rules Function) 204, a service provider server 205, a serving gateway or packet data network gateway 206, and a service proxy 207. Generally, the setting of the service optimization rule can be completed by a node such as an OSS/BSS, a PCRF, or a service agent. As shown in FIG. 2, the service optimization agent may obtain a service optimization rule from an operation and service support system OSS/BSS, a policy and charging function PCRF, or a service agent, and the service optimization rule includes at least: a service optimization agent provides a service terminal. The type of terminal, or the type of service that the service optimizes the agent to provide.

The service optimization agent can set the service optimization rules according to various parameter information obtained from the OSS/BSS, the PCRF, or the service agent.
然后，服务优化代理可以将业务优化规则发送给eNB。eNB接收到业务优化规则后，进行业务优化规则设置。在进行了业务优化规则设置之后，eNB只将符合优化规则的业务转发至服务优化代理，并且将不符合优化规则的业务直接转发至S-GW，而不发送给服务优化代理。The service optimization agent can then send the traffic optimization rules to the eNB. After receiving the service optimization rule, the eNB performs service optimization rule setting. After the service optimization rule is set, the eNB forwards only the service that meets the optimization rule to the service optimization agent, and forwards the service that does not meet the optimization rule to the S-GW directly, instead of sending it to the service optimization agent.
图3示出了根据本发明实施例的执行业务优化规则的数据流图。在图3中，业务优化***300根据业务优化规则进行数据业务的处理和转发。图3中示出的用于执行业务优化规则的实体包括：用户终端UE 301、eNB 302、服务优化代理303、P-GW 304、服务代理305和内容服务器306。FIG. 3 illustrates a data flow diagram of performing a service optimization rule in accordance with an embodiment of the present invention. In FIG. 3, the service optimization system 300 performs processing and forwarding of data services according to service optimization rules.

服务代理305确定服务优化代理303的方法如下：服务代理305预先在本地存储服务优化代理与eNB的对应关系。服务代理305向P-GW 304查询获取UE的IP地址所归属的eNB的信息(例如，eNB的小区ID(Cell ID)或者eNB ID或者eNB IP)。服务代理305根据eNB的信息确定UE所对应的服务优化代理。The method by which the service agent 305 determines the service optimization agent 303 is as follows: The service agent 305 stores the correspondence between the service optimization agent and the eNB in advance. The service proxy 305 queries the P-GW 304 for information of the eNB to which the IP address of the UE belongs (e.g., the cell ID (Cell ID) or eNB ID or eNB IP of the eNB). The service proxy 305 determines the service optimization proxy corresponding to the UE according to the information of the eNB.
步骤2，服务优化代理根据eNB信息确定当前的服务eNB，然后请求服务eNB完成业务优化规则的设置，如图3的规则建立阶段307中的步骤1和2所示。所述请求中携带的参数信息可以为：UE的IP地址、业务的URL等。eNB完成业务优化规则的设置可以包括：建立业务优化规则绑定表。所述业务优化规则绑定表可以包括：UE的IP地址(IP addr)，上行链路(UL，UpLink)基于UDP(User Datagram Protocol)的GPRS隧道协议(General Packet Radio Service Tunneling Protocol)隧道端点标识(TEID，Tunnel Endpoint ID Identifier)UL GTP-U TEID，下行链路(DL，DownLink)基于UDP(User Datagram Protocol)的GPRS隧道协议(General Packet Radio Service Tunneling Protocol)隧道端点标识(TEID:Tunnel Endpoint ID Identifier)DL GTP-U TEID等。Step 2: The service optimization agent determines the current serving eNB according to the eNB information, and then requests the serving eNB to complete the setting of the service optimization rule, as shown in steps 1 and 2 in the rule establishing phase 307 of FIG. The parameter information carried in the request may be: an IP address of the UE, a URL of the service, and the like.

步骤3，完成TCP代理/HTTP代理建立准备。 Step 3. Complete the preparation of the TCP proxy/HTTP proxy setup.
步骤4，服务优化代理303向服务代理305发送业务优化规则建立就绪消息，通知业务优化规则建立完成。Step 4: The service optimization agent 303 sends a service optimization rule establishment ready message to the service proxy 305 to notify the establishment of the service optimization rule.
步骤5，开启业务优化规则应用模式。Step 5: Enable the business optimization rule application mode.
根据本发明实施例，在业务优化规则建立阶段307完成并且服务优化代理303启动TCP代理之后，可以进行业务优化规则执行阶段308(Execution phase)，具体为：According to the embodiment of the present invention, after the service optimization rule establishment phase 307 is completed and the service optimization agent 303 starts the TCP proxy, the service optimization rule execution phase 308 (Execution phase) may be performed, specifically:
步骤1，用户终端请求视频分片#n(视频分片的显示格式例如是1080p)，即请求编号为n的视频分片。 Step 1. The user terminal requests the video fragment #n (the display format of the video fragment is, for example, 1080p), that is, requests the video fragment numbered n.
步骤2，eNB 302根据所设定的业务优化规则，确定针对视频分片#n的请求是否符合业务优化规则，即进行规则匹配。如果所述请求符合业务优化规则，则eNB 302将对应于UE的IP地址的UL GTP-U TEID的数据包路由 到服务优化代理303。如果所述请求不符合业务优化规则，则将所述请求路由到S-GW(下面将会详细介绍)。作为响应，服务代理305把通过与DASH服务器交互所获取的视频分片#n(1080p)或者服务代理305中缓存的视频分片#n(1080p)发送给eNB 302，图中未示出。Step 2: The eNB 302 determines, according to the set service optimization rule, whether the request for the video fragment #n complies with the service optimization rule, that is, performs rule matching. If the request conforms to the service optimization rule, the eNB 302 routes the packet of the UL GTP-U TEID corresponding to the IP address of the UE. Go to the Service Optimization Agent 303. If the request does not comply with the business optimization rules, the request is routed to the S-GW (described in more detail below). In response, the service agent 305 transmits the video slice #n (1080p) obtained by interaction with the DASH server or the video slice #n (1080p) buffered in the service agent 305 to the eNB 302, which is not shown.
步骤2*，eNB 302将针对视频分片#n(1080p)的请求转发到服务代理305。In step 2*, the eNB 302 forwards the request for video shard #n (1080p) to the service proxy 305.
步骤3，eNB 302对针对视频分片#n(1080p)的请求进行复制，并且将所复制的请求转发给服务优化代理303。In step 3, the eNB 302 copies the request for the video slice #n (1080p) and forwards the copied request to the service optimization agent 303.
步骤4，服务优化代理303启动TCP代理功能，从而实现TCP代理过程，并且根据所述请求所涉及的数据进行处理，例如，确定视频分片#n(1080p)是否存储在服务优化代理303的本地缓存中。 Step 4, the service optimization agent 303 starts the TCP proxy function, thereby implementing the TCP proxy process, and processing according to the data involved in the request, for example, determining whether the video slice #n (1080p) is stored locally in the service optimization agent 303. In the cache.
步骤5，如果服务优化代理303确定服务优化代理303的本地缓存中存储了视频分片#n(1080p)，则构造HTTP响应(HTTP Response)消息，即构建Rsp响应消息(response message)。Step 5: If the service optimization agent 303 determines that the video fragment #n (1080p) is stored in the local cache of the service optimization agent 303, constructs an HTTP response (HTTP Response) message, that is, constructs an Rsp response message.
步骤6，服务优化代理303向eNB 302发送视频分片#n(1080p)以作为回复，发送Rsp#n(1080p)。In step 6, the service optimization agent 303 sends a video fragment #n (1080p) to the eNB 302 as a reply, and transmits Rsp#n (1080p).
步骤7，eNB 302向用户终端转发视频分片#n(1080p)，以作为用户终端发送的请求的响应。In step 7, the eNB 302 forwards the video fragment #n (1080p) to the user terminal as a response to the request sent by the user terminal.
步骤8，服务优化代理303向服务代理305发送发送成功指示信息，所述成功指示信息表明服务优化代理303已经将视频分片#n(1080p)发送给用户终端。In step 8, the service optimization agent 303 sends a transmission success indication message to the service agent 305 indicating that the service optimization agent 303 has transmitted the video fragment #n (1080p) to the user terminal.
步骤9，服务代理305把通过与DASH服务器交互所获取的视频分片#n(1080p)或者服务代理305中缓存的视频分片#n(1080p)发送给P-GW304，并且服务代理305将丢弃指示信息发送给P-GW 304。其中，丢弃指示消息中携带内容丢弃指示。P-GW 304根据从服务代理305接收的视频分片#n(1080p)完成计费监听，并根据所述丢弃指示消息中的内容丢弃指示，丢弃视频分片#n(1080p)。Step 9, the service proxy 305 sends the video fragment #n (1080p) obtained by interaction with the DASH server or the video fragment #n (1080p) buffered in the service proxy 305 to the P-GW 304, and the service proxy 305 will discard The indication information is sent to the P-GW 304. The discarding indication message carries a content discarding indication. The P-GW 304 completes the charging snooping according to the video fragment #n (1080p) received from the service proxy 305, and discards the video fragment #n (1080p) according to the content discarding indication in the discarding indication message.

步骤a)，在业务优化规则执行阶段308的步骤4之后并且在步骤5之前，在针对视频分片#n的请求符合业务优化规则的情况下，并且在服务优化代理303启动TCP代理功能完成之后，服务优化代理303向服务代理305发送TCP状态切换指示：将服务优化代理303的状态设置为“规则匹配”TCP状态。应当了解的是，此步骤a)为可选步骤。Step a), after step 4 of the service optimization rule execution phase 308 and before step 5, in the case where the request for video tile #n complies with the service optimization rule, and after the service optimization agent 303 starts the TCP proxy function The service optimization agent 303 sends a TCP state switch indication to the service agent 305: the state of the service optimization agent 303 is set to the "rule match" TCP state. It should be understood that this step a) is an optional step.
在用户终端进行小区切换的场景下，源eNB通过与目标eNB的交互来确定目标eNB是否支持业务优化规则的设置和代理。如果目标eNB不支持业务优化规则的设置和代理，则在小区切换之前，用户终端通知服务优化代理303启动切换过程，随后服务优化代理303向服务代理305发送TCP状态切换指示：将服务代理305的状态设置为正常处理状态。In a scenario in which the user terminal performs cell handover, the source eNB determines whether the target eNB supports the setting and proxy of the service optimization rule by interacting with the target eNB. If the target eNB does not support the setting and proxy of the service optimization rule, before the cell handover, the user terminal notifies the service optimization agent 303 to initiate the handover procedure, and then the service optimization proxy 303 sends a TCP state handover indication to the service proxy 305: the service proxy 305 The status is set to normal processing status.
步骤b)服务优化代理303与服务代理305进行交互，以完成TCP同步，即服务优化代理303将eNB和服务优化代理303之间传送的TCP分组的最新序列号发送给服务代理。在业务优化规则执行阶段308中在进行业务交互时，服务优化代理303与服务代理之间周期性进行上述步骤b)。Step b) The service optimization agent 303 interacts with the service agent 305 to complete the TCP synchronization, ie the service optimization agent 303 sends the latest sequence number of the TCP packet transmitted between the eNB and the service optimization agent 303 to the service agent. When the business interaction is performed in the business optimization rule execution phase 308, the above-mentioned step b) is periodically performed between the service optimization agent 303 and the service agent.

The parameters carried in the service optimization rule failure indication information include: service content attribute information (for example, a video service URL), and a service optimization rule setting parameter (for example, the IP of the UE) Address) and so on.
步骤2，服务优化代理402向eNB 401发送业务优化规则失效指示信息，请求eNB 401完成业务优化规则失效操作。Step 2: The service optimization agent 402 sends the service optimization rule failure indication information to the eNB 401, requesting the eNB 401 to complete the service optimization rule invalidation operation.

图5示出了根据本发明另一实施例的对业务优化规则进行失效处理的数据流图500。如图5所示，对业务优化规则进行失效处理涉及eNB 501、服务优化代理502和服务代理503。由eNB 501发起的业务优化规则失效过程为：FIG. 5 illustrates a data flow diagram 500 for failing a service optimization rule in accordance with another embodiment of the present invention. As shown in FIG. 5, the failure processing of the service optimization rule involves the eNB 501, the service optimization agent 502, and the service agent 503. The service optimization rule invalidation process initiated by the eNB 501 is:
步骤1，eNB 501向服务优化代理502发送业务优化规则失效指示信息。所述业务优化规则失效指示信息中携带的参数包括：业务内容属性信息(如视频业务URL)、业务优化规则设定参数(例如UE的IP地址)等。In step 1, the eNB 501 sends the service optimization rule failure indication information to the service optimization agent 502. The parameters carried in the service optimization rule failure indication information include: service content attribute information (such as a video service URL), a service optimization rule setting parameter (such as an IP address of the UE), and the like.
步骤2，服务优化代理502根据eNB 501发送的业务优化规则失效指示信息来进行业务优化规则失效操作。Step 2: The service optimization agent 502 performs a service optimization rule invalidation operation according to the service optimization rule failure indication information sent by the eNB 501.

图6示出了根据本发明另一实施例的执行业务优化规则的数据流图。在图6中，业务优化***600根据业务优化规则进行收数据业务的处理和转发。图6中示出的用于执行业务优化规则的实体包括：用户终端UE 601、eNB602、Savi 603、P-GW 604、DASH代理605和DASH服务器(DASH Svr)606。其中，Savi 603用于实现服务优化代理的功能并且，DASH代理605用于实现服务代理的功能。本实施例与前述实施例的主要区别在于：在本 实施例中，实现服务代理功能的DASH代理605建立UE的IP地址和URL的业务优化规则绑定关系后，将绑定关系通过带内信令(HTTP扩展头域或者TCP选项字段扩展，即TCP Opt字段扩展)传送给Savi 603。而在前述实施例中，DASH代理605将业务优化规则绑定关系通过带外信令发送给Savi603。其中，带内信令是指信号的频率在话音频率范围之内(0.3～3.4kHz)。带外信令，又叫共路信令，是一种采用在信息传输频率/信道之外的频率/信道传输信令技术。简言之，带内信令是在语音频带(300-3400Hz)之内传送的信令。带外信令是在语音频带之外传送的信令。FIG. 6 shows a data flow diagram of performing a service optimization rule according to another embodiment of the present invention. In FIG. 6, the service optimization system 600 performs processing and forwarding of the data collection service according to the service optimization rule. The entity for performing the service optimization rule shown in FIG. 6 includes: user terminal UE 601, eNB 602, Savi 603, P-GW 604, DASH proxy 605, and DASH server (DASH Svr) 606. Among them, Savi 603 is used to implement the function of the service optimization agent and the DASH agent 605 is used to implement the function of the service agent. The main difference between this embodiment and the foregoing embodiment is: In an embodiment, the DASH proxy 605 that implements the service proxy function establishes a binding relationship between the IP address of the UE and the service optimization rule of the URL, and then extends the binding relationship by using inband signaling (HTTP extended header field or TCP option field extension, that is, TCP). The Opt field extension is passed to the Savi 603. In the foregoing embodiment, the DASH proxy 605 sends the service optimization rule binding relationship to the Savi 603 through out-of-band signaling. Among them, in-band signaling means that the frequency of the signal is within the range of the voice frequency (0.3 to 3.4 kHz). Out-of-band signaling, also known as common-channel signaling, is a frequency/channel transmission signaling technique that uses information transmission frequencies/channels. In short, in-band signaling is signaling that is transmitted within the voice band (300-3400 Hz). Out-of-band signaling is signaling that is transmitted outside the voice band.
图6中的规则建立阶段607(Rule setup phase)示出了根据另一实施例的业务优化规则的建立过程。在建立业务优化规则之前，用户终端UE 601发送针对视频分片#1(显示格式例如是1080p)的请求，即针对编号为1的视频分片的请求给P-GW 604。P-GW 604转发用户终端UE 601的请求到DASH代理605。DASH代理605确定本地缓存中是否保存了视频分片#1。如果DASH代理605的本地缓存中没有视频分片#1(1080p)，则向DASH服务器606发送请求信息以获取视频分片#1(1080p)。The rule setup phase 607 in FIG. 6 shows the process of establishing a service optimization rule according to another embodiment. Prior to establishing the service optimization rule, the user terminal UE 601 sends a request for video tile #1 (display format, for example, 1080p), ie, a request for video slice numbered 1 to P-GW 604. The P-GW 604 forwards the request of the user terminal UE 601 to the DASH proxy 605. The DASH proxy 605 determines if video fragment #1 is saved in the local cache. If there is no video fragment #1 (1080p) in the local cache of the DASH proxy 605, the request information is sent to the DASH server 606 to obtain video fragment #1 (1080p).
根据本发明的实施例，所述请求信息的实例可以是：According to an embodiment of the present invention, an example of the request information may be:
GET http://media.example.com/media1_1080p.mp4/Fragments(video＝1)GET http://media.example.com/media1_1080p.mp4/Fragments(video=1)

步骤1，DASH代理605向Savi 603发送包含视频分片#1(1080p)的回复信息。回复信息中携带业务优化规则建立指示。其中，业务优化规则建立指示中携带如下内容：业务内容属性信息(例如，视频业务URL)、业务优化规则设定参数(例如，用户终端UE的IP地址)、eNB信息、TCP信息和/或应用信息等。通常，可以在TCP选项(TCP Opt)字段中进行业务 优化规则建立的标识或者在HTTP扩展头域中携带业务优化规则建立指示。In step 1, the DASH proxy 605 sends a reply message containing the video tile #1 (1080p) to the Savi 603. The reply message carries an indication of establishing a business optimization rule. The service optimization rule establishment indication carries the following content: service content attribute information (for example, a video service URL), a service optimization rule setting parameter (for example, an IP address of the user terminal UE), eNB information, TCP information, and/or an application. Information, etc. Typically, you can do business in the TCP Options field. The identifier established by the optimization rule or the service optimization rule establishment indication is carried in the HTTP extension header field.
通常，还可以通过增加新的HTTP头域服务优化规则(Service-Optimization-Rule)来携带业务优化规则建立指示。例如，Service-Optimization-Rule：UE IP；URL；Service Type(服务类型)。In general, the service optimization rule establishment indication can also be carried by adding a new HTTP header field service optimization rule (Service-Optimization-Rule). For example, Service-Optimization-Rule: UE IP; URL; Service Type.

除此之外，业务优化规则建立指示可以在TCP选项option(TCP Opt)字段中体现，即在图7中TCP头域的选项option字段添加指示信息以指示建立业务优化规则。如果将业务优化规则设定为Savi 603只处理HTTP流传输(HTTP Streaming)业务，则选项option字段中的前两个字节标识选项字段的用途。例如，本发明中设置业务优化规则，则第三字节和第四字节标识进行优化处理的业务类型。例如，业务优化规则为01，并且HTTP Streaming业务标识为11。因此，通过在TCP选项option字段里填上0111，则可以指示业务优化规则和HTTP Streaming。In addition, the service optimization rule establishment indication may be embodied in a TCP option option (TCP Opt) field, that is, an indication information is added in the option option field of the TCP header field in FIG. 7 to indicate establishment of a service optimization rule. If the service optimization rule is set to Savi 603 to process only HTTP Streaming services, the first two bytes in the option option field identify the purpose of the option field. For example, in the present invention, the service optimization rule is set, and the third byte and the fourth byte identify the service type to be optimized. For example, the service optimization rule is 01 and the HTTP Streaming service identifier is 11. Therefore, by enclosing 0111 in the option field of the TCP option, you can indicate the service optimization rule and HTTP Streaming.

The confirmation information further includes service optimization rule setup ready information to notify the DASH agent 605 that the service optimization rule is established. The service optimization rule establishment ready information can be carried in the TCP option option field.

图9示出了根据本发明再一实施例的执行业务优化规则的数据流图900。图9中实现业务优化的实体涉及eNB 901、服务优化代理902和S-GW903。如图9所示，在eNB 901中存储一个或多个用户终端的上下文。例如，用户终端1的上下文包括：上行链路UL的默认载波(HTTP GET(流传输应用1)+其他应用)、下行链路DL的默认载波(对应用1和其他应用的业务的进行流传送)、上行链路UL的GBR载波1(应用3(VoIP))以及下行链路DL的GBR载波1(应用3(VoIP))。以及用户终端n的上下文，即上行链路的默认载波(BE业务)。FIG. 9 illustrates a data flow diagram 900 for performing a traffic optimization rule in accordance with yet another embodiment of the present invention. The entity implementing service optimization in FIG. 9 involves an eNB 901, a service optimization agent 902, and an S-GW 903. As shown in FIG. 9, the context of one or more user terminals is stored in the eNB 901. For example, the context of the user terminal 1 includes: a default carrier of an uplink UL (HTTP GET (Streaming Application 1) + other applications), a default carrier of a downlink DL (streaming of services of Application 1 and other applications) ) GBR carrier 1 (Application 3 (VoIP)) of the uplink UL and GBR carrier 1 (Application 3 (VoIP)) of the downlink DL. And the context of the user terminal n, that is, the default carrier (BE service) of the uplink.
本实施例介绍eNB 901的业务优化规则匹配过程。eNB 901进行业务优化规则的设置，例如建立业务优化规则绑定表。业务优化规则绑定表如表1所示，业务优化规则绑定表的参数信息包括：UE信息(如UE的IP地址)、业务承载信息(如UL GTP-U TEID，DL GTP-U TEID)等。相同的UE IP地址/UE标识符ID(Identifier)与一个或多个UDL GTP TEIDL 或DL GTP TEID相关联。eNB 901将与业务优化规则相匹配的隧道传输协议GTP流路由到服务优化代理以用于业务优化。并且将其他非匹配的GTP流直接路由到S-GW。This embodiment describes a service optimization rule matching process of the eNB 901. The eNB 901 performs setting of a service optimization rule, for example, establishing a service optimization rule binding table. The service optimization rule binding table is shown in Table 1. The parameter information of the service optimization rule binding table includes: UE information (such as the IP address of the UE) and service bearer information (such as UL GTP-U TEID, DL GTP-U TEID). Wait. Same UE IP address/UE identifier ID (Identifier) and one or more UDL GTP TEIDL Or associated with DL GTP TEID. The eNB 901 routes the tunneling protocol GTP flow that matches the traffic optimization rules to the service optimization agent for service optimization. And other non-matching GTP flows are directly routed to the S-GW.

…... …...
eNB 901收到用户终端1发送的业务请求，通过检查规则绑定关系表，确定承载GTP-U TEID-1和GTP-U TEID-11上的业务，需要通过服务优化代理参与业务优化。对于上行业务UL GTP-U TEID-1(例如视频流业务的HTTP GET请求消息)，eNB 901将其转发给服务优化代理。对于下行业务DL GTP-U TEID-11(例如视频流业务的HTTP响应消息)，需要经由服务优化代理902处理后发送给eNB 901。对于与业务优化规则绑定关系表中的内容不相匹配的业务，如用户终端在承载GTP-U TEID-2、GTP-U TEID-12的业务，则其上下行数据直接转发给S-GW 903，不需要发送给服务优化代理902。The eNB 901 receives the service request sent by the user terminal 1 and checks the rule binding relationship table to determine the services on the GTP-U TEID-1 and the GTP-U TEID-11. The service optimization agent needs to participate in the service optimization. For the uplink service UL GTP-U TEID-1 (e.g., the HTTP GET request message for the video stream service), the eNB 901 forwards it to the service optimization agent. For the downlink service DL GTP-U TEID-11 (for example, the HTTP response message of the video stream service), it needs to be processed by the service optimization agent 902 and then sent to the eNB 901. For services that do not match the content in the service optimization rule binding relationship table, for example, if the user terminal is carrying services of GTP-U TEID-2 and GTP-U TEID-12, the uplink and downlink data are directly forwarded to the S-GW. 903, need not be sent to the service optimization agent 902.
图10示出了根据本发明的又一实施例执行业务优化规则的数据流图1000。本实施例与图9中的实施例不同在于，本实施例不需要eNB进行业务优化规则设置。对于上行业务，eNB直接转发给服务优化代理。对于下行业务，由S-GW直接转发给服务优化代理。服务优化代理对S1-U接口数据进行检测找出对应UE ip地址的GTP-U隧道，然后在通过HTTP层内容的检测，确定流媒体对应的ip flow，则进行优化处理。检测完成之后，不对应的IP业务可以透传。Figure 10 illustrates a data flow diagram 1000 for performing a business optimization rule in accordance with yet another embodiment of the present invention. The difference between this embodiment and the embodiment in FIG. 9 is that the eNB does not need to perform service optimization rule setting. For uplink traffic, the eNB forwards directly to the service optimization agent. For the downlink service, the S-GW directly forwards it to the service optimization agent. The service optimization agent detects the S1-U interface data to find a GTP-U tunnel corresponding to the UE ip address, and then determines the ip flow corresponding to the streaming media by detecting the content of the HTTP layer, and then performs optimization processing. After the detection is completed, the non-corresponding IP services can be transparently transmitted.
