Testing tool is meant the instrument that network element is tested and managed that does not belong to the OMC functional category, signaling tracing instrument for example, base station testing orientation tool etc.
The transmission system of network element message, comprise the Channel server that is positioned at operation maintenance center, be connected with a plurality of network elements with a plurality of testing tools, be used for after testing tool is determined target network element and sent test post, described test post is forwarded to described target network element, also is used for the test response message of described target network element is transmitted to described testing tool.
As shown in Figure 1, transparent channel is integrated among the OMC as a separate modular, can connect with a plurality of network elements and a plurality of testing tool simultaneously.Each testing tool can carry out message to one or more network elements by transparent channel and transmit, and each network element can be by transparent channel to one or more testing tool feedback messages.Form the relation of " multi-to-multi " between network element and the testing tool.
Accurate, unobstructed for guaranteeing the message transmission between network element under this relation and network element testing tool.Transparent channel need be safeguarded the state of link between network element and the testing tool and the addressing work of message.
Transparent channel is created testing tool agency and network element agency respectively for the network element and the testing tool of each connection, and testing tool is acted on behalf of the Link State of maintenance test instrument, and the network element agency safeguards the Link State of network element.In the maintenance link process, whether by handshake information or heartbeat detection, it is normal to detect link, and recovers automatically when link disconnects.
Addressing in the transparent channel mainly appears at following two kinds of situations:
(1) transparent channel obtains the message from testing tool, and which network element judgement will mail to;
(2) transparent channel obtains from network element message, and which testing tool judgement will mail to.
According to the above-mentioned addressing description on opportunity, for the transparent message body of transmitting between testing tool and the network element, need add that the addressing mark finishes the addressing of message, the concrete practice is to add message header on transparent message.
As shown in Figure 2, transparent message comprises message header and transparent message body.Each transparent message all comprises a transparent message header, by the content of transparent channel according to transparent message header, message is carried out processing forward, and transparent channel is not interfered the content of message body, thereby has realized transparent forwarding.
As shown in Figure 3, message header comprises, message event number (eventId), sender ID (senderId), recipient ID (receiverId), message body length (msgLen).
