技术领域technical field

本发明涉及无线通信技术领域，尤其涉及一种数据路由方法、装置和基站。The present invention relates to the technical field of wireless communication, in particular to a data routing method, device and base station.

背景技术Background technique

随着移动互联网技术和智能终端技术的发展，手机等移动终端作为人们必备的移动通信工具，已从简单的通话工具向智能化发展，演变成一个移动的个人信息收集和处理平台，越来越多的互联网业务可以通过移动终端进行访问，如QQ、微信、微博、OTT(over the top)业务等。With the development of mobile Internet technology and intelligent terminal technology, mobile terminals such as mobile phones, as people's necessary mobile communication tools, have evolved from simple communication tools to intelligent development, and have evolved into a mobile personal information collection and processing platform. More Internet services can be accessed through mobile terminals, such as QQ, WeChat, Weibo, OTT (over the top) services, etc.

现有的通过移动终端进行业务访问的流程中，所有移动终端的上行数据都要通过基站(eNB)传输给核心网中的业务网关(Serving Gateway，S-GW)，再由S-GW交由共用数据网(PDN，Public Data Network)网关，最后发送给业务服务器，而针对业务服务器发送给终端的下行数据同样需要经由核心网中的S-GW传输给移动终端所属基站，再由基站发送给移动终端，因此，现有的数据处理方式需要穿梭在核心网和无线接入网之间。In the existing process of service access through mobile terminals, all uplink data of mobile terminals must be transmitted to the Serving Gateway (S-GW) in the core network through the base station (eNB), and then handed over by the S-GW to the The shared data network (PDN, Public Data Network) gateway is finally sent to the service server, and the downlink data sent to the terminal by the service server also needs to be transmitted to the base station to which the mobile terminal belongs via the S-GW in the core network, and then sent to the base station by the base station. Mobile terminals, therefore, the existing data processing methods need to shuttle between the core network and the radio access network.

而随着互联网业务的发展，基于“社交圈”的局部资源共享成为新兴的移动通信模式，本地数据流量在总业务量中占比越来越多。即便如此，根据上述的数据传输方式，就算是同一基站下的两个移动终端相互通信，源终端发送给目的终端的数据也要通过基站传输给S-GW，再由S-GW发送给PDN网关，进而接入业务服务器，通过业务服务器再发送给基站，再由基站发送给目的终端。由此可见，上述的数据传输方式中，一方面存在有路由迂回，增加了数据传输时延；另一方面，增加了核心网网元的信令负荷。With the development of Internet services, local resource sharing based on "social circles" has become an emerging mobile communication mode, and local data traffic accounts for an increasing proportion of the total business volume. Even so, according to the above data transmission method, even if two mobile terminals under the same base station communicate with each other, the data sent by the source terminal to the destination terminal must be transmitted to the S-GW through the base station, and then sent to the PDN gateway by the S-GW , and then connected to the service server, and then sent to the base station through the service server, and then sent to the destination terminal by the base station. It can be seen that, in the above-mentioned data transmission mode, on the one hand, there is a roundabout route, which increases the data transmission delay; on the other hand, it increases the signaling load of the network element of the core network.

为解决上述问题，现有技术提出了本地IP接入(LIPA，Local IP Access)和选择IP数据分流(SIPTO，Selected IP Traffic Offload)技术。LIPA技术通过在基站侧部署本地网关(L-GW)使得数据从基站侧进行分流，而SIPO技术允许在靠近用户的位置、以分布的方式部署网关设备，以将某些类型业务转移到离UE附着接入点较近的网络节点上，在选择为UE(User Equipment，用户设备)服务的GW(包括S-GW和P-GW(分组数据网关))时选择离UE附着点地理位置/逻辑位置较近的GW，以缓解核心网网元的信令负荷，但是，由于部署的网关设备本质上仍然属于核心网网元，因此，采用LIPA技术和SIPTO技术后，核心网的信令负荷仍然较大，且该两种方案还需要在基站侧额外部署本地网关，也增加了硬件成本。To solve the above problems, the prior art proposes local IP access (LIPA, Local IP Access) and selected IP traffic offload (SIPTO, Selected IP Traffic Offload) technologies. LIPA technology allows data to be offloaded from the base station side by deploying a local gateway (L-GW) on the base station side, while SIPO technology allows gateway devices to be deployed in a distributed manner close to the user to transfer certain types of services to off-site UEs. On the network node that is closer to the attachment access point, when selecting the GW (including S-GW and P-GW (packet data gateway)) serving the UE (User Equipment, user equipment), select the geographic location/logic away from the UE attachment point The GW located nearer to alleviate the signaling load of the core network elements. However, since the deployed gateway devices still belong to the core network elements in essence, after adopting LIPA technology and SIPTO technology, the signaling load of the core network remains the same. In addition, the two solutions also need to additionally deploy a local gateway on the base station side, which also increases the hardware cost.

具体实施方式detailed description

为了减少数据传输过程中核心网网元的信令负荷，降低硬件部署成本，本发明实施例提供了一种数据路由方法和装置。In order to reduce the signaling load of core network elements during data transmission and reduce hardware deployment costs, embodiments of the present invention provide a data routing method and device.

以下结合说明书附图对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明，并且在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention, and in the absence of conflict, the present invention The embodiments and the features in the embodiments can be combined with each other.

发明人发现，在现有的数据传输方法中，基站在接收到待传输的数据包后，需要将数据包路由至核心网由核心网进行处理，但是对于一些本地数据业务，这种传输方式一方面增加了数据路由迂回，增大了数据传输延迟；另一方面，也增加了核心网网元的心灵处理负荷，虽然LIPA和SIPTO技术在一定程度上能够缓解核心网网元的信令处理负荷，但是由于该两种技术均需要新增网关设备，一方面新增的网关设备仍然属于核心网，使得核心网网元的信令负荷仍然较大，另一方面，也增加了硬件成本开销。The inventor found that in the existing data transmission method, after the base station receives the data packet to be transmitted, it needs to route the data packet to the core network for processing by the core network, but for some local data services, this transmission method is always On the one hand, it increases data routing detours and increases data transmission delay; on the other hand, it also increases the mental processing load of core network elements, although LIPA and SIPTO technologies can alleviate the signaling processing load of core network elements to a certain extent , but because both of these two technologies require new gateway devices, on the one hand, the newly added gateway devices still belong to the core network, so that the signaling load of the core network elements is still relatively large; on the other hand, the hardware cost is also increased.

为此，本发明实施例提供了一种应用于基站中的数据路由方法，在基站接收到待路由的数据包之后，如果判断出当前正在进行的业务为本地业务，则基站与相应的本地业务服务器建立本地路由连接，并通过建立的本地路由连接将待路由的数据包直接路由至本地业务服务器，而不再发送给核心网处理。由此，大大减少了核心网网元的信令处理负荷，由于上述流程在基站中即可完成处理，无需再增加新的网络设备，从而降低了硬件成本开销。For this reason, the embodiment of the present invention provides a data routing method applied in the base station. After the base station receives the data packet to be routed, if it is judged that the service currently in progress is a local service, the base station and the corresponding local service The server establishes a local routing connection, and directly routes the data packet to be routed to the local service server through the established local routing connection, instead of sending it to the core network for processing. As a result, the signaling processing load of the core network element is greatly reduced, and since the above process can be completed in the base station, there is no need to add new network equipment, thereby reducing the hardware cost.

在介绍了本发明的基本原理之后，下面具体介绍本发明的各种非限制性实施方式。After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below.

首先参考图1，其为本发明实施例的应用场景示意图。基站(eNB)在接收到数据路由请求时，如果根据数据路由请求确定当前正在进行的业务为本地业务，则基站与本地网络中的本地业务服务器建立本地路由连接，并将接收到的数据包路由到本地路由服务器进行处理，否则，基站通过针对当前业务建立的核心网专用业务承载将接收到的数据包路由到EPC(Evolved Packet Corenetwork，演进型分组核心网)进行处理，由EPC根据待路由的数据包将其路由至互联网(Internet)中的相应业务服务器进行处理。例如，图1中的本地网络可以为校园网，用户利用用户终端在校园内访问校园图书管，则本地网络中的本地业务服务器可以为校园图书馆服务器。First refer to FIG. 1 , which is a schematic diagram of an application scenario of an embodiment of the present invention. When the base station (eNB) receives the data routing request, if it determines that the current ongoing service is a local service according to the data routing request, the base station establishes a local routing connection with the local service server in the local network, and routes the received data packet to the local routing server for processing; otherwise, the base station will route the received data packet to the EPC (Evolved Packet Core network, evolved packet core network) through the core network dedicated service bearer established for the current business for processing, and the EPC will process it according to the The data packets are routed to corresponding service servers in the Internet (Internet) for processing. For example, the local network in FIG. 1 may be a campus network, and users use user terminals to access campus libraries on campus, so the local service server in the local network may be a campus library server.

下面结合图1的应用场景，参考图2来描述根据本发明示例性实施方式的数据路由方法。需要注意的是，上述应用场景仅是为了便于理解本发明的精神和原理而示出，本发明的实施方式在此方面不受任何限制。相反，本发明的实施方式可以应用于适用的任何场景。The following describes a data routing method according to an exemplary embodiment of the present invention with reference to FIG. 2 in conjunction with the application scenario of FIG. 1 . It should be noted that the above application scenarios are only shown for the purpose of understanding the spirit and principle of the present invention, and the implementation manners of the present invention are not limited in this respect. On the contrary, the embodiments of the present invention can be applied to any applicable scene.

如图2所示，其为本发明实施例提供的数据路由方法的实施流程示意图，可以包括以下步骤：As shown in FIG. 2, it is a schematic diagram of the implementation flow of the data routing method provided by the embodiment of the present invention, which may include the following steps:

S21、接收数据路由请求。S21. Receive a data routing request.

其中，在接收到的数据路由请求中携带有待路由的数据包。其中用户终端在进行业务访问时，向业务服务器发送的数据包需要经过基站进行转发。Wherein, the data packet to be routed is carried in the received data routing request. When the user terminal performs service access, the data packet sent to the service server needs to be forwarded by the base station.

S22、根据接收到的数据路由请求判断当前正在进行的业务是否为本地业务，如果是，则执行步骤S23，否则执行步骤S25；S22. Judging whether the currently ongoing service is a local service according to the received data routing request, if yes, execute step S23, otherwise execute step S25;

S23、与本地业务服务器建立本地路由连接。S23. Establish a local routing connection with the local service server.

S24、将接收到的数据包通过建立的本地路由连接路由到本地业务服务器，流程结束。S24. Route the received data packet to the local service server through the established local routing connection, and the process ends.

S25、与EPC建立核心网专用业务承载；S25. Establish a core network dedicated service bearer with the EPC;

S26、将接收到的数据包通过建立的核心网专用业务承载路由到相应的业务服务器。S26. Route the received data packet to the corresponding service server through the established core network dedicated service bearer.

具体实施时，基站接收到数据路由请求可能有以下两种情况：一种情况为针对用户终端发往业务服务器的数据包而发送的数据路由请求，另一种为针对业务服务器发往用户终端数据包而发送的数据路由请求。如果为针对用户终端发往业务服务器的数据包而发送的数据路由请求，通常该数据路由请求首先到达基站，因此，这种情况下，基站可以对接收到的数据路由请求进行分析后，判断用户终端当前正在进行的业务是否为本地业务，如果是，则直接与本地业务服务器建立本地路由连接，而无需向核心网请求建立专用承载以转发接收到的数据包；而针对业务服务器发往用户终端的数据包而发送的数据路由请求，这种情况下，即使该业务服务器为本地业务服务器，由于业务服务器无法判断当前业务是否为本地业务，因此，其需要通过核心网将数据包发送给基站，并由基站发送给用户终端，也就是说这种情况下在基站接收到数据包时已经建立核心网专用业务承载。后续，基站在接收到针对用户终端发往业务服务器的数据包而发送的数据路由请求后，如果基站如果判断出当前正在进行的业务为本地业务，则与相应的本地业务服务器建立本地路由连接，再直接将数据包通过建立的本地路由连接路由到本地业务服务器即可。为了节约传输资源，基站可以向MME(Mobility Management Entity，移动性管理实体)发送资源释放请求，以释放已经建立的核心网专用业务承载；或者仅释放核心网专用业务承载中用户数据承载，保留控制数据承载。During specific implementation, the base station may receive the data routing request in the following two cases: one case is the data routing request sent for the data packet sent by the user terminal to the service server, and the other is the data packet sent by the service server to the user terminal The data routing request sent by the packet. If the data routing request is sent for the data packet sent by the user terminal to the service server, usually the data routing request first reaches the base station. Therefore, in this case, the base station can analyze the received data routing request and determine whether the user Whether the current business of the terminal is a local business, if so, directly establish a local routing connection with the local business server, without requesting the core network to establish a dedicated bearer to forward the received data packet; and for the business server to send to the user terminal In this case, even if the service server is a local service server, since the service server cannot determine whether the current service is a local service, it needs to send the data packet to the base station through the core network. And sent by the base station to the user terminal, that is to say, in this case, when the base station receives the data packet, the core network dedicated service bearer has been established. Subsequently, after the base station receives the data routing request sent for the data packet sent by the user terminal to the service server, if the base station determines that the currently ongoing service is a local service, it establishes a local routing connection with the corresponding local service server, Then directly route the data packet to the local service server through the established local routing connection. In order to save transmission resources, the base station can send a resource release request to the MME (Mobility Management Entity, Mobility Management Entity) to release the established core network dedicated service bearer; or only release the user data bearer in the core network dedicated service bearer, and retain the control data bearer.

具体实施时，基站中可以集成地址解析和路由转换功能，基于此，步骤S22中可以按照以下任一方式确定当前正在进行的业务是否为本地业务：During specific implementation, address resolution and routing conversion functions can be integrated in the base station. Based on this, in step S22, it can be determined whether the currently ongoing service is a local service in any of the following ways:

第一种实施方式、用户终端在发送的数据路由请求中携带有相应的指示信息。In the first implementation manner, the data routing request sent by the user terminal carries corresponding indication information.

这种实施方式下，可以由UE(用户终端)在发送的数据路由请求中携带有指示当前正在进行的业务为本地业务的指示信息，由此，步骤S22中，可以根据接收到的数据路由请求中携带的指示信息确定UE当前正在进行的业务是否为本地业务。具体实施时，可以用一个字节的信息指示基站，例如，用“1”指示当前正在进行的业务为本地业务，用“0”指示当前正在进行的业务不是本地业务。基站在接收到数据路由请求后，如果确定该指示信息为“1”，则确定UE当前正在进行为业务为本地业务，如果确定该指示信息为“0”，则可以确定UE当前正在进行为业务不是本地业务。In this embodiment, the data routing request sent by the UE (user terminal) may carry indication information indicating that the current service is a local service, so that in step S22, the data routing request may be received according to The indication information carried in determines whether the current service of the UE is a local service. During specific implementation, one byte of information can be used to indicate the base station, for example, "1" is used to indicate that the current ongoing service is a local service, and "0" is used to indicate that the current ongoing service is not a local service. After receiving the data routing request, if the base station determines that the indication information is "1", it determines that the UE is currently conducting a service as a local service; if it determines that the indication information is "0", it can determine that the UE is currently conducting a service Not a local business.

具体实施时，如果基站确定出UE当前正在进行的业务为本地业务，则与相应的本地业务服务器建立本地路由连接。具体的，基站可以向本地业务服务器发送连接建立请求，在接收到本地业务服务器返回的响应消息后，确定与本地业务服务器建立本地路由连接成功。During specific implementation, if the base station determines that the current service being performed by the UE is a local service, it establishes a local routing connection with a corresponding local service server. Specifically, the base station may send a connection establishment request to the local service server, and after receiving a response message returned by the local service server, determine that the local routing connection with the local service server is successfully established.

较佳的，如果在建立本地路由连接之前，已经为UE建立了核心网承载，则把当前正在进行的业务转移到建立的本地路由连接上，即UE与本地业务服务器之间发送的数据包不再经过已建立的核心网承载。为了节约核心网资源，还可以在建立本地路由连接后，释放为该UE建立的核心网专用业务承载，或者释放部分核心网资源，例如，仅释放该UE的用户数据承载，而保留控制数据承载。Preferably, if the core network bearer has been established for the UE before the local routing connection is established, the current ongoing service is transferred to the established local routing connection, that is, the data packets sent between the UE and the local service server do not Then pass through the established core network bearer. In order to save core network resources, after the local routing connection is established, the core network dedicated service bearer established for the UE can be released, or part of the core network resources can be released, for example, only the user data bearer of the UE can be released, while the control data bearer can be reserved. .

具体实施时，如果当前部署的本地业务服务器存在多个，则基站在与本地业务服务器建立连接之前，需要首先确定当前业务对应的本地业务服务器。例如，基站可以为数据包进行识别，以获得其中包含的业务标识，基站根据获得的业务标识与相应的本地业务服务器建立本地路由连接。具体的，基站可以采用深度包检测技术获得数据包中包含的业务标识等。较佳的，具体实施时，基站还可以预先存储业务标识与相应的本地业务服务器的IP(互联网协议)地址之间的对应关系，这样，在获得了业务标识之后，基站可以根据该业务标识对应的本地业务服务器的IP地址，与相应的本地业务服务器建立本地路由连接。During specific implementation, if there are multiple local service servers currently deployed, the base station needs to first determine the local service server corresponding to the current service before establishing a connection with the local service server. For example, the base station can identify the data packet to obtain the service identifier contained therein, and the base station establishes a local routing connection with a corresponding local service server according to the obtained service identifier. Specifically, the base station may use a deep packet inspection technology to obtain service identifiers and the like included in the data packet. Preferably, during specific implementation, the base station can also pre-store the correspondence between the service identifier and the IP (Internet Protocol) address of the corresponding local service server, so that after obtaining the service identifier, the base station can correspond to the service identifier according to the service identifier. The IP address of the local service server, and establish a local routing connection with the corresponding local service server.

第二种实施方式、基站根据数据路由请求中携带的URL(统一资源定位符)确定当前正在进行的业务是否为本地业务。In the second embodiment, the base station determines whether the currently ongoing service is a local service according to the URL (Uniform Resource Locator) carried in the data routing request.

这种实施方式下，在用户终端向业务服务器发起业务访问请求时，针对用户终端向业务服务器发送的数据包而发送的数据路由请求中携带有该业务服务器对应的URL，基站解析该URL得到其对应的IP地址，并判断解析得到的IP地址是否在自身预先存储的本地业务服务器IP地址列表中，如果是，则可以确定UE当前正在进行的业务为本地业务，如果否，则基站可以确定UE当前正在进行的业务不是本地业务。In this implementation mode, when the user terminal initiates a service access request to the service server, the data routing request sent for the data packet sent by the user terminal to the service server carries the URL corresponding to the service server, and the base station parses the URL to obtain its URL. The corresponding IP address, and judge whether the IP address obtained by parsing is in the local service server IP address list stored in itself, if yes, it can be determined that the current service of the UE is a local service, if not, the base station can determine that the UE The business currently in progress is not a local business.

如果基站根据解析得到的IP地址确定UE当前正在进行的业务为本地业务，则在步骤S23中，基站可以根据解析得到的IP地址于相应的本地业务服务器建立本地路由连接，并通过建立的本地路由连接将待路由的数据包路由给本地业务服务器。If the base station determines that the current service of the UE is a local service according to the IP address obtained through analysis, then in step S23, the base station can establish a local routing connection with the corresponding local service server according to the IP address obtained through analysis, and through the established local route The connection routes the data packets to be routed to the local service server.

至此，基站完成本地业务数据包的本地转发。So far, the base station completes the local forwarding of the local service data packet.

本发明实施例提供的数据路由方法中，由基站判断终端当前进行的业务是否为本地业务，如果基站判断出UE当前进行的业务为本地业务，将与本地业务服务器建立本地路由连接，并将待路由的数据包直接路由至本地业务服务器，而不再通过核心网进行路由，由此，减少了核心网网元的信令负荷，另一方面，由于本发明实施例提供的数据路由方法可以由基站执行，而无需增加新的设备，因此，降低了硬件成本开销。In the data routing method provided by the embodiment of the present invention, the base station judges whether the service currently performed by the terminal is a local service. If the base station determines that the service currently performed by the UE is a local service, it will establish a local routing connection with the local service server, and will The routed data packets are directly routed to the local service server instead of routing through the core network, thereby reducing the signaling load of the network elements of the core network. On the other hand, since the data routing method provided by the embodiment of the present invention can be performed by The base station performs without adding new equipment, thus reducing the hardware cost overhead.

基于同一发明构思，本发明实施例中还提供了一种数据路由装置和基站，由于上述装置及设备解决问题的原理与数据路由方法相似，因此上述装置及设备的实施可以参见方法的实施，重复之处不再赘述。Based on the same inventive concept, a data routing device and a base station are also provided in the embodiment of the present invention. Since the problem-solving principle of the above-mentioned device and equipment is similar to the data routing method, the implementation of the above-mentioned device and equipment can refer to the implementation of the method.
