Step S402, for GK relaying H.323, SS1 constructs a LRQ message (with a last fixing number) at set intervals, is sent to SS2, and message sends the back and starts timer and wait for the response of SS2 to LRQ (Location Request, location request message).
Step S404~S406, SS2 handles by normal LRQ message if receive the LRQ of SS 1:
If the H.323 GK relaying of SS1 is not pointed in configuration, then do not do any response.
Step S404, called as if navigating to, then respond LCF (LocationConfirmation, location confirmation message).
Step S406, called as if not navigating to, then respond LRJ (Location Reiect, location reject message).
Step S408, SS1 then put this relay state for normal if received the response message (LCF or LRJ) of SS2 to LRQ before timer expiry.
Step S410, SS1 is not if also receive any response of SS2 to LRQ at timer expiry, it is undesired then putting this relay state.
If SS2 will detect the state of the GK relaying that points to SS1, also need the LRQ message that regular transmission detects as SS1.
Embodiment two: H.323 GW-OUT GK relay state detects and realizes
Fig. 5 shows the H.323 GW-OUTGK relay networking figure according to the embodiment of the invention; Fig. 6 shows relaying detection method according to the present invention and is applied to message flow chart in the H.323GW-OUTGK relay networking among Fig. 5.

Step S602, H.323 GW sends RRQ (Registration Request, login request message) to the GK registration, starts the response message that timer is waited for RRQ.
Step S604, GK judge that GW succeeds in registration, then will and GW between relay state be changed to normally.
Step S606, GW then think and succeed in registration if receive the response message RCF (Registration Confirmation, registration confirmation message) of GK to RRQ, put and GK between the state of relaying for normal.
Step S608, GW receive refuse information RRJ (Registration Reject at the response message of still not receiving RRQ behind the timer expiry or before overtime, registration reject message), then think registration failure, put and GK between the state of relaying be undesired.
Step S610, GK receive that never registration message, GW registration failure or the GW of GW successfully registered the back and initiate registration again in the time that both sides consult, then will and GW between the state of relaying be changed to undesired.
As can be seen from the above description, the present invention has realized following technique effect:
The present invention passes through realization to the relaying status detection, thereby has solved the problem that can not select normal relaying striking out in the correlation technique, is particularly useful for H.323 network.
