As shown in Fig. 1 , the interface on the side of the
但是由于不同的PW上的抖动、缓冲都不一致，导致各路PW上发送的分片报文之间的时延差会很大，而基站控制器14能够容忍的报文重组时延差很小，所以当PW多的时候，基站控制器14对收到的分片报文进行重组时可能会失败，从而导致分片报文丢弃。However, due to the inconsistent jitter and buffering on different PWs, the delay difference between the fragmented messages sent on each PW will be very large, and the packet reassembly delay difference that the

具体实施方式Detailed ways
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
下面将结合附图和具体实施例进一步说明本发明实施例的技术方案。The technical solutions of the embodiments of the present invention will be further described below in conjunction with the drawings and specific embodiments.
本发明各实施例所涉及的报文是PPP报文，上述报文主要包含链路控制协议层（Link Control Protocol，简称LCP）报文、网络控制协议层（NetworkControl Protocol，简称NCP）报文和业务报文。The messages involved in the various embodiments of the present invention are PPP messages, and the above-mentioned messages mainly include Link Control Protocol layer (Link Control Protocol, referred to as LCP) messages, Network Control Protocol layer (Network Control Protocol, referred to as NCP) messages and business message.
图2是本发明报文处理方法实施例一的流程图，如图2所示，该方法包括：Fig. 2 is a flowchart of Embodiment 1 of the message processing method of the present invention. As shown in Fig. 2, the method includes:
S101、接入控制设备通过MP组接口接收网元设备通过MP组发送的PPP分片报文，MP组中包含多条PPP链路。S101. The access control device receives the PPP fragmented message sent by the network element device through the MP group through the MP group interface, and the MP group includes multiple PPP links.
具体地，网元设备可以是基站，基站与接入控制设备之间通过MP组连接，并且MP组中包含多条PPP链路，PPP链路可以是E1链路，基站将PPP报文分片后，通过MP组中的多条PPP链路发送至设置有MP组接口的接入控制设备，接入控制设备可以是网络中的任一接入控制设备，例如，多业务传送平台，接入控制设备上设置有多个的MP组接口，每个MP组接口对应一个MP组，用以接收网元设备通过MP组发送的分片报文。Specifically, the network element device may be a base station, and the base station and the access control device are connected through an MP group, and the MP group includes multiple PPP links, and the PPP link may be an E1 link, and the base station fragments the PPP packet Afterwards, it is sent to the access control device equipped with the MP group interface through multiple PPP links in the MP group. The access control device can be any access control device in the network, for example, a multi-service transmission platform, access Multiple MP group interfaces are set on the control device, and each MP group interface corresponds to an MP group to receive fragmented messages sent by network element devices through the MP group.
接入控制设备，可以连接一个基站，也可以连接多个基站，并且在实际应用中，每个基站与接入控制设备之间建立的PPP链路数量可以相同，也可以不同，在此不做任何限制。The access control device can be connected to one base station or multiple base stations, and in practical applications, the number of PPP links established between each base station and the access control device can be the same or different, which will not be discussed here. any restrictions.
S102、接入控制设备将PPP分片报文封装入PW报文中，并通过一路PW发送至对端接入控制设备。S102. The access control device encapsulates the PPP fragmented message into a PW message, and sends it to the peer access control device through one PW.
具体地，如果网元设备为基站，则相应地对端网元设备可以为基站控制器；如果网元设备为基站控制器，则相应地，对端网元设备为基站，本发明以网元设备为基站，对端网元设备为基站控制器的通信过程为例进行说明，而基站控制器为网元设备、基站为对端网元设备的通信过程与网元设备为基站，对端网元设备为基站控制器的通信过程类似，在此不再赘述。接入控制设备可以对MP接口接收到的分片报文封装入伪线报文中，并通过一路PW发送至对端接入控制设备，以供对端接入控制设备通过与基站控制器之间的MP组中的多条PPP链路发送给基站控制器。Specifically, if the network element device is a base station, the opposite network element device can be a base station controller; if the network element device is a base station controller, then correspondingly, the opposite network element device is a base station, and the present invention uses The communication process in which the device is a base station and the peer network element device is a base station controller is described as an example. The base station controller is a network element device, the base station is a peer network element device, and the network element device is a base station. The peer network element device is a base station. The communication process in which the meta-device is a base station controller is similar, and will not be repeated here. The access control device can encapsulate the fragmented message received by the MP interface into a pseudowire message, and send it to the peer access control device through a PW, so that the peer access control device can communicate with the base station controller Multiple PPP links in the inter-MP group are sent to the base station controller.
举例来说，接入控制设备接收到PPP分片报文后，可以经过重组再封装入PW报文，也可以直接封装入PW报文，在此并不做任何限制。如果接入控制设备接收到分片报文后，直接封装入PW报文，并通过一路PW发送至对端接入控制设备，则对端接入控制设备接收PW报文后，解析该PW报文，获得该PW报文中携带的分片报文，然后向对端网元设备传送分片报文，这样对端网元设备接收到的各分片报文之间的时延差很小，保证了对端网元设备对分片报文重组的成功率；如果接入控制设备对接收到的多个分片报文进行重组，经过重组后的多个分片报文成为一个完整的PPP报文，然后将该完整的PPP报文封装入PW报文后，再通过一路PW进行发送，对端接入控制设备接收到PW报文后，解析该PW报文，恢复出完整的PPP报文，然后对端接入控制设备通过连接基站控制器的MP组接口将恢复出来的PPP报文再次分片后，通过基站控制器与对端接入控制设备之间的MP组发送至基站控制器，此时基站控制器接收的到的分片报文的时延差也很小，基站控制器对接收到的分片报文进行重组，提取需要的信息进行相关处理。可以理解，接入控制设备对接收到的各分片报文重组后再封装入PW报文，可以节约传输过程中的资源。For example, after receiving the PPP fragmented message, the access control device may reassemble it and then encapsulate it into a PW message, or directly encapsulate it into a PW message, and there is no limitation here. If the access control device receives the fragmented message, it directly encapsulates it into a PW message and sends it to the peer access control device through a PW, then the peer access control device parses the PW message after receiving the PW message. To obtain the fragmented message carried in the PW message, and then transmit the fragmented message to the peer network element device, so that the delay difference between the fragmented messages received by the peer network element device is very small , which ensures the success rate of reorganizing fragmented packets by the peer network element device; if the access control device reassembles multiple received fragmented packets, the reassembled multiple fragmented packets become a complete PPP message, and then encapsulate the complete PPP message into a PW message, and then send it through a PW. After receiving the PW message, the peer access control device parses the PW message and restores the complete PPP message. Then the peer access control device fragments the restored PPP message through the MP group interface connected to the base station controller, and sends it to the base station through the MP group between the base station controller and the peer access control device The controller, at this time, the delay difference of the fragmented messages received by the base station controller is also very small, and the base station controller reassembles the received fragmented messages, extracts the required information and performs related processing. It can be understood that the access control device reassembles each received fragmented message and then encapsulates it into a PW message, which can save resources in the transmission process.
举例来说，分片后的报文在传送过程中，为了便于识别，需要对分片后的报文进行相应地标号处理，以使对端接入控制设备或是分片报文的接收端可以对相应的报文进行识别，保证正确的接收顺序。For example, in the transmission process of the fragmented message, in order to facilitate identification, it is necessary to label the fragmented message accordingly, so that the peer end can access the control device or the receiving end of the fragmented message The corresponding message can be identified to ensure the correct receiving sequence.
本发明实施例提供的报文处理方法，通过一路PW发送接入控制设备接收到的MP组中多条PPP链路上发来的分片报文，由于使用一路PW发送所接收到的分片报文，相对于现有技术中使用多路PW进行发送的方法保证了网元设备发出的各分片报文到达对端接入控制设备上的时延差很小，从而提高了分片报文到达基站控制器后进行重组的成功率，进而大大提高了数据传输的可靠性。The message processing method provided by the embodiment of the present invention uses one PW to send the fragmented messages received by the access control device from multiple PPP links in the MP group. Compared with the method of using multiple PWs in the prior art to send the message, it ensures that the time delay difference between each fragmented message sent by the network element device and reaching the access control device at the opposite end is very small, thereby improving the fragmentation rate. After the file reaches the base station controller, the success rate of recombination is greatly improved, which greatly improves the reliability of data transmission.
图3是本发明报文处理方法实施例二的流程图，本实施例为实施例一的优选实施方案，与本发明实施例一的技术方案的区别在于：本实施例中的MP组接口和一路PW具有一定的映射关系，该映射关系可以是预先设置的。如图3所示，本发明实施例二提供的报文处理方法包括：Fig. 3 is a flow chart of Embodiment 2 of the message processing method of the present invention. This embodiment is a preferred implementation solution of Embodiment 1, and the difference from the technical solution of Embodiment 1 of the present invention lies in: the MP group interface and the MP group interface in this embodiment One PW has a certain mapping relationship, and the mapping relationship may be preset. As shown in FIG. 3, the message processing method provided by Embodiment 2 of the present invention includes:
S201、预先配置MP组接口和一路PW的映射关系。S201. Pre-configure the mapping relationship between the MP group interface and one PW.
具体地，接入控制设备上可以设置有多个MP组接口，每个MP组接口绑定一定数量的PPP链路，各个MP组接口承载的业务可以是不同的，也可以是相同的，因此在接入控制设备与对端接入控制设备之间的一路PW是存在相应的映射关系，例如接入控制设备上的MP接口1绑定的多条PPP链路接收的是基站发送的数据业务，接入控制设备上的MP接口2绑定的多条PPP链路接收的是基站发送的语音业务，因此在实际应用中，不同的业务类型使用的一路PW也是不同的，因此需要将MP组接口和一路PW的映射关系预先配置，以便于接入控制设备将对应的MP组接口上收到的报文发送至对应的PW上。Specifically, multiple MP group interfaces can be set on the access control device, each MP group interface is bound to a certain number of PPP links, and the services carried by each MP group interface can be different or the same, so There is a corresponding mapping relationship between the access control device and the peer access control device on one PW. For example, the multiple PPP links bound to MP interface 1 on the access control device receive data services sent by the base station. , the multiple PPP links bound to MP interface 2 on the access control device receive the voice service sent by the base station. Therefore, in practical applications, different service types use different PWs. Therefore, the MP group needs to be The mapping relationship between an interface and a PW is configured in advance, so that the access control device can send the packets received on the interface of the corresponding MP group to the corresponding PW.
S202、接入控制设备通过MP组接口接收网元设备通过MP组发送的PPP分片报文，MP组中包含多条PPP链路。S202. The access control device receives the PPP fragmented message sent by the network element device through the MP group through the MP group interface, and the MP group includes multiple PPP links.
S203、接入控制设备将PPP分片报文封装入PW报文中，并通过一路PW发送至对端接入控制设备。S203. The access control device encapsulates the PPP fragmented message into a PW message, and sends it to the peer access control device through one PW.
在本实施例中，S202和S203与实施例一中的S101和S102的原理及效果一致，在此不再赘述。In this embodiment, the principles and effects of S202 and S203 are consistent with those of S101 and S102 in Embodiment 1, and will not be repeated here.
本发明实施例提供的报文处理方法，通过预先配置MP组接口和一路PW的映射关系，在接入控制设备通过MP组接口接收到分片报文封装后，根据预设的MP组接口和PW的对应关系，将封装后的伪线报文发送至相应地的一路PW上。通过一路PW将报文发送至对端接入控制设备，使得网元设备发出的分片报文到达对端接入控制设备的时延差很小，从而提高了分片报文到达基站控制器后进行重组的成功率，进而大大提高了数据传输的可靠性。In the message processing method provided by the embodiment of the present invention, by pre-configuring the mapping relationship between the MP group interface and one PW, after the access control device receives the fragmented message encapsulation through the MP group interface, according to the preset The corresponding relationship of the PW, the encapsulated pseudowire message is sent to a corresponding PW. The message is sent to the access control device at the opposite end through one PW, so that the delay difference between the fragmented message sent by the network element device and the access control device at the opposite end is very small, thereby improving the speed at which the fragmented message reaches the base station controller Afterwards, the success rate of reorganization is improved, which greatly improves the reliability of data transmission.
在上述各实施例中的分片报文可以是NCP报文，还可以是业务报文或LCP报文。如果分片报文为NCP报文，在S101之前还可以包括：LCP报文的处理协商过程，具体为：The fragmented message in the foregoing embodiments may be an NCP message, or may be a service message or an LCP message. If the fragmented message is an NCP message, it may also include before S101: the processing and negotiation process of the LCP message, specifically:
接入控制设备接收到LCP报文后，与网元设备进行LCP协商，或，After receiving the LCP message, the access control device performs LCP negotiation with the network element device, or,
接入控制设备将接收到的LCP报文通过一路PW传送至对端接入控制设备，以实现LCP报文在基站和基站控制器之间的协商。The access control device transmits the received LCP message to the peer access control device through one PW, so as to realize the negotiation of the LCP message between the base station and the base station controller.
具体地，如果接入控制设备接收LCP报文后，直接与网元设备进行LCP协商，在这种情况下，接入控制设备需要根据接收到的报文的协议域确定该报文是否为LCP报文。Specifically, if the access control device directly performs LCP negotiation with the network element device after receiving the LCP message, in this case, the access control device needs to determine whether the message is LCP according to the protocol field of the received message. message.
在LCP报文通过一路PW发送至对端接入控制设备时，可以根据预先配置的基站与接入控制设备之间的PPP链路与对端接入控制设备与基站控制器之间的PPP链路的对应关系，选择对应的PPP链路将LCP报文传送至基站控制器。When the LCP message is sent to the peer access control device through one PW, it can be based on the pre-configured PPP link between the base station and the access control device and the PPP link between the peer access control device and the base station controller. According to the corresponding relationship between the paths, the corresponding PPP link is selected to transmit the LCP message to the base station controller.
