Embodiment Construction
[0032] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention .
[0033] figure 1 Shown is a schematic structural diagram of an embodiment of a monitoring system of the present invention.
[0034] The monitoring center and the monitored network element are connected through at least n (n≥2) links (such as E1 links), and each link includes 32 time slots (TS1~TS332), of which time slots TS1 and TS17 are used for synchronized with the clock. In this embodiment, two time slots are taken out of the total 30 time slots of time slots TSi (2≤i≤16) and TSj (18≤j≤32) for multiplexing the information of X1 and X2 channels respectively, and other 28 time slots are used to transmit information of the X3 channel.

The invention relates to a monitored link switching device, which comprises a link control module, a call monitoring module and a database module, wherein the link control module and the call monitoring module are used to monitor whether a current monitored link is abnormal; the database module is used to re-determine a monitored link among all available links when the current monitored link is abnormal; and the call monitoring module is also used to judge whether the abnormal monitored link has a monitored speech path and switch the monitored link if the monitored speech path exists. The invention also provides a network element and a monitored link switching method. The monitored link switching device, the monitored link switching method and the network element for setting the monitored link switching device in the embodiment of the invention not only can multiplex messages of X1, X2 and X3 channels through the links to monitor monitored network elements, but also can switch the monitored links if the monitored links are abnormal in the monitoring process.
Description
technical field [0001] The present invention relates to switching technology in the communication field, in particular to a monitoring link switching device, a method for switching the monitoring link and a network element. Background technique [0002] Lawful interception is based on the requirements of national laws, authorizing national security agencies to require network operators or service providers to provide specific interception results to specific interception authorities or enforcement agencies (LEA). At this time, the operator needs to provide a monitor trigger interface, and the equipment manufacturer needs to provide a solution for monitoring network-side voice and event transmission. [0003] Utilizing the switching and processing capabilities of the telecommunication exchange system and the existing telecommunication business functions, the monitoring personnel can realize the target of being monitored by setting the monitored number and the monitored number...
