一种传输信令二层对等适配层 Transmission signaling layer 2 peer-to-peer adaptation layer
故障链路快速拆除的方法 技术领域 本发明涉及 IP网络信令传输协议（ SIGTRAN协议；)， 尤其涉及 MTP2对 等适配协议（M2PA协议）发生丢包错序等异常情况时的一种快速拆除故障信 令链路的方法。 背景技术 随着 IP网络技术的逐步成熟， 出现了在 IP网络上传输七号信令等电路交 换信令协议的需求。为了满足在 IP网络上传输信令协议的需求， IETF ( Internet Engineering Task Force, 因特网工程任务組） 网络工作组成立了专门的信令传 输小组， 他们所制订的 IP 网络信令传输协议 ( SIGTRAN协议） 支持通过 IP 网络传输传统电路交换信令。 2005年， IETF工作组正式发布了 MTP2对等适 配层协议（M2PA, MTP2 Peer to Peer Adaption Layer ), M2PA协议用来实现 载在 IP网络上的两个 MTP3 ( Message Transfer Part LeveB , 信息传输部分第 3 级）对等协议实体之间消息的可靠有序传递。 2002年， 我国信息产业部也正式 发布了 M2PA的通信行业标准。 M2PA具体的协议结构如附图 1、 附图 2所示。 TECHNICAL FIELD The present invention relates to an IP network signaling transmission protocol (SIGTRAN protocol), and particularly relates to a rapid demolition of an abnormal situation such as a packet loss misordering of an MTP2 peer-to-peer adaptation protocol (M2PA protocol). Method of fault signaling link. BACKGROUND OF THE INVENTION With the gradual maturity of IP network technologies, there has been a demand for transmitting circuit switching signaling protocols such as SS7 on IP networks. In order to meet the requirements of transmitting signaling protocols over IP networks, the Internet Engineering Task Force (IETF) Network Working Group has established a dedicated signaling transport group, which has developed an IP network signaling transport protocol (SIGTRAN protocol). ) Supports traditional circuit switched signaling over IP networks. In 2005, the IETF working group officially released the MTP2 Peer to Peer Adaption Layer (MTP) protocol. The M2PA protocol is used to implement two MTP3 (Message Transfer Part LeveB, information transmission part) carried on the IP network. Level 3) Reliable and orderly delivery of messages between peer-to-peer protocol entities. In 2002, China's Ministry of Information Industry also officially released the M2PA communication industry standard. The specific protocol structure of M2PA is shown in Figure 1 and Figure 2.
M2PA作为 IP网络中的传输信令二层是直接承载在 SCTP( Stream control Transmission Protocol, 流控制传输协议）协议（ RFC2960 )实体上的， 而 SCTP 协议实体具备可靠有序传输的特性。因此在 RFC协议标准以及我国通信行业标 准中都没有对 M2PA的可靠有序传输机制进行进一步的描述。 但是 M2PA作为处于 MTP3 协议实体之下的传输信令链路层， 是通过 SCTP协议实体以及 M2PA协议实体来共同完成 MTP3 协议实体间消息的可靠 有序传输。当 SCTP两个对等协议实体间在 IP网络传输过程中如果发生了丢包、 乱序等错误情况时， 在 SCTP协议实体间可以通过重传等机制来保证序号的恢 复同步。 但是当 M2PA协议实体与 SCTP协议实体间发生消息丢失等异常情况 时，消息接收方 M2PA协议实体会一直抛弃发送方 M2PA协议实体发送过来的 不连续序号的数据^ =艮文， 而消息发送方 M2PA协议实体由于不清楚之前发生的 消息丢失情况所以会持续不断的发送消息给 M2PA接收方协议实体。 此异常情 况一直持续到发送方 M2PA 十办议实体检测到丢包消息长时间无应答导致发送 Out of Service (退出服务）给接收方 M2PA协议实体。 随后进行 MTP3数据回 取以及信令链路的倒换操作， 严重情况下甚至可能会导致信令局向不可达等异 常情况。 此异常情况描述参见附图 3。 并且对于 M2PA对等协议实体间的丢包 错序， 信令链路一定会发生链路瞬断， 但是目前的检测机制是依靠消息发送方 的应答定时器来检测， 时间相对较长， 一^:为秒级别左右。 发明内容 为了克服上述缺陷，本发明的目的在于提供一种传输信令二层对等适配层 故障链路快速拆除的方法， 该方法解决了在 M2PA协议实体接收到失序 MSU 导致需要较长时间拆除故障链路问题。 为达到上述目的 ,本发明提供了一种传输信令二层对等适配层故障链路快 速拆除的方法， 其中， 接收到失序消息信令单元的 M2PA协议实体主动发起释 放信令链路操作。 接收到失序消息单元的 M2PA协议实体主动发起释放信令链路操作的方 法具体为： As the transmission signaling layer 2 in the IP network, M2PA is directly carried on the SCTP (Stream Control Transmission Protocol) (RFC2960) entity, and the SCTP protocol entity has the characteristics of reliable and orderly transmission. Therefore, there is no further description of the reliable and orderly transmission mechanism of M2PA in the RFC protocol standard and China's communication industry standards. However, M2PA, as the transport signaling link layer under the MTP3 protocol entity, is used to complete the reliable and orderly transmission of messages between MTP3 protocol entities through the SCTP protocol entity and the M2PA protocol entity. When an error condition such as packet loss or out-of-order occurs in the IP network transmission process between the two peer-to-peer protocol entities of the SCTP, the SCTP protocol entity can ensure the synchronization of the sequence number recovery through retransmission and other mechanisms. However, when an abnormality such as a message loss occurs between the M2PA protocol entity and the SCTP protocol entity, the message receiver M2PA protocol entity will always discard the data of the discontinuous sequence number sent by the sender M2PA protocol entity, and the message sender M2PA The protocol entity is unclear because it happened before The message is lost, so the message is continuously sent to the M2PA receiver protocol entity. This abnormal situation continues until the sender M2PA ten-party entity detects the packet loss message and does not answer for a long time, causing the Out of Service to be sent to the receiver M2PA protocol entity. The MTP3 data retrieval and the switching of the signaling link are performed, and in severe cases, the abnormal situation such as the unreachable signaling office may be caused. See Figure 3 for a description of this anomaly. Moreover, for the packet loss misordering between the M2PA peering protocol entities, the signaling link must have a link short-circuit, but the current detection mechanism relies on the message sender's response timer to detect, and the time is relatively long. : Around the second level. SUMMARY OF THE INVENTION In order to overcome the above drawbacks, an object of the present invention is to provide a method for rapidly dismantling a faulty link of a Layer 2 peer-to-peer adaptation layer of a signaling signaling, which solves the problem that it takes a long time to receive the out-of-order MSU in the M2PA protocol entity. Remove the faulty link problem. In order to achieve the above object, the present invention provides a method for rapidly dismantling a faulty link of a transmission layering peer-to-peer adaptation layer, wherein the M2PA protocol entity that receives the out-of-order message signaling unit initiates a release signaling link operation. .

( 3 )发送失序消息信令单元的 M2PA协议实体接收到接收失序消息信令 单元的 M2PA协议实体发送的值为 "退出服务" 的链路状态信令单元后， 发送 失序消息信令单元的 M2PA协议实体终止定时器； (3) The M2PA protocol entity that sends the out-of-order message signaling unit receives the link state signaling unit with the value of "exit service" sent by the M2PA protocol entity that receives the out-of-order message signaling unit, and sends the M2PA of the out-of-order message signaling unit. The protocol entity terminates the timer;
( 4 )发送失序消息信令单元的 M2PA协议实体向上层用户 MTP3上报信 令链路退出月 务， 同时置信令链路状态为退出月良务。 本发明提供的传输信令二层对等适配居故障链路快速拆除的方法， 是对(4) The M2PA protocol entity that sends the out-of-order message signaling unit reports the signaling link to the upper-layer user MTP3 to exit the monthly service, and sets the signaling link status to exit the monthly service.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail below with reference to the accompanying drawings. The main inventive principle of the present invention is: The M2PA protocol entity that receives the out-of-order message unit actively initiates the release of the signaling link operation to avoid the problem that a long time interval is required to remove the faulty link when the signaling link is interrupted. The embodiment of the invention provides a method for quickly removing the fault link of the Layer 2 peer-to-peer adaptation layer of the transmission signaling. The method is further described in detail below with reference to FIG. 3 and FIG. 4. As shown in FIG. 3, in the current M2PA protocol, the M2PA protocol entity_B sends the MSU to the M2PA protocol entity_曱, and for the M2PA protocol entity_A, since the M2PA protocol entity_B is not received, the MSU: FSN =7 BSN=6 (where: MSU is the Message Signal Unit message signaling unit, FSN is Forward Sequence Number forward sequence J 'J number, BSN is Backward Sequence Number backward sequence number; FSN is sent on behalf of the current sender M2PA protocol entity The number of the message signaling unit, BSN represents the number of the message signaling unit currently received from the peer M2PA protocol entity:), so the MSU sent by the subsequently received M2PA protocol entity_B will always be discarded. This condition will continue until the M2PA protocol entity—the MSU corresponding to B: FSN=7 BSN=6 packet waiting for the response timer Timer T7 timeout (see the related M2PA protocol for the specific processing procedure), and send the LSSU to the M2PA protocol entity-A: Out The Service begins to release the signaling link. From the description of the protocol flow, it can be found that once packet loss occurs between M2PA protocol entities, the release of the M2PA signaling link will inevitably occur. The time interval for the removal of the faulty link must be within the Timer T7 time interval. If the traffic of the upper layer user message unit of the M2PA protocol entity is relatively large, a large number of data packets are discarded between the M2PA peer protocol entities. Therefore, under the current technical solution, as long as the out-of-sequence situation occurs, the signaling link must be broken. The method provided by the embodiment of the present invention quickly removes the faulty signaling link that has been out of order. The existing protocol described in FIG. 3 is improved according to the method of the embodiment of the present invention. As shown in FIG. 4, the LSSU is actively sent when the receiving M2PA protocol entity detects that the message unit of the out-of-order FSN is received. Of Service to release the signaling link. The specific operation is shown in Figure 5. As shown in FIG. 5, the method for quickly removing a faulty link of a Layer 2 peer-to-peer adaptation layer according to an embodiment of the present invention includes the following steps: Step S502: The M2PA protocol entity-A receives the out-of-order message unit MSU; Step S504: The M2PA protocol entity-A sends the LSSU: Out of Service to the M2PA protocol entity_B; Step S506: The M2PA protocol entity-A reports to the upper-layer user MTP3 The signaling link exits the service, and the signaling link status is Out of Service; Step S508: The M2PA protocol entity receives the LSSU sent by the M2PA protocol entity_A: Out of Service, and terminates the Timer T7; Step S510: Μ2ΡΑ The protocol entity _ B reports to the upper layer user ΜΤΡ 3 to exit the service, and sets the signaling link status to Out of Service. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalents, and modifications made within the spirit and principles of the present invention. Wen Jin et al. are intended to be included within the scope of the present invention.
