Abstract

The invention discloses a detection processing method for a signaling connection control part (SCCP) loop. The method comprises the following steps of: performing global title (GT) routing processing on a connectionless service message transmitted from a second network element by using a first network element; according to a routing result, judging whether a called address in the connectionless service message is modified or not, and judging whether the routed network element of the next hop is the second network element or not; and if the called address is not modified and the routed network element of the next hop is the second network element, determining that the SCCP loop is produced between the first and second network elements. The SCCP loop is judged whether to exist or not by the routing result, so higher efficiency and wider application range are ensured. In addition, the operation of realizing the detection of the SCCP loop based on a hop counter is performed in advance before service processing, so the influence of SCCP loop detection delay on a service is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the field of network communication technologies, and in particular to a method and device for detecting and processing an SCCP (Signaling Connection Control Part, signaling connection control part) loop. Background technique [0002] As an important member of No.7 (Signaling System No.7, No. 7 signaling system), the SCCP protocol is widely used in communication networks. If there is a conflict in the data planning between different network elements in the communication network, it will cause a loop at the SCCP layer of the message (that is, an SCCP loop), causing the message to oscillate among multiple network elements, occupying a large amount of network bandwidth and CPU ( Central Processing Unit, central processing unit) resource. [0003] For the XUDT (Extended unitdata, enhanced unit data) message and LUDT (Long unitdata, long unit data) message in the connectionless service message, the SCCP pro...
