Embodiment 1

[0049] Embodiment 1: H.323 GK relay status detection implementation:

[0050] Fig. 3 shows the H.323 GK relay network diagram according to the embodiment of the present invention; Fig. 4 shows the application of the relay detection method according to the present invention in the H.323 GK relay network in Fig. 3 Message flow diagram.

[0051] As shown in Figure 3, SS (SoftSwitch) is used as a GK application, and the peer device is a GK in the same H.323 network (or a GK in other H.323 networks), and H. 323 GK relay. The relay state setting is shown in Figure 4, including the following steps:

[0052] Step S402, for the H.323 GK relay, SS1 constructs an LRQ message (with a fixed number) every once in a while, and sends it to SS2. After the message is sent, start a timer and wait for SS2 to respond to LRQ (Location Request, location request) message) response.

[0053] In steps S404-S406, if SS2 receives the LRQ from SS1, it will process it as a normal LRQ message:

Embodiment 2

[0060] Embodiment 2: Implementation of H.323 GW-OUT GK relay status detection

[0061] Fig. 5 shows the H.323 GW-OUTGK relay network diagram according to the embodiment of the present invention; Fig. 6 shows that the relay detection method according to the present invention is applied to the H.323GW-OUTGK relay group in Fig. 5 Message flow diagram in the network.

[0062] As shown in FIG. 5 , the SS is used as a GK application, and the peer device is a GW in the same H.323 network; or, the SS is used as an H.323 GW application, and the peer device is a GK in the same H.323 network. The relay state setting is shown in Figure 6, including the following steps:

[0063] In step S602, the H.323 GW sends a RRQ (Registration Request, registration request message) to register with the GK, and starts a timer to wait for the RRQ response message.

[0064] In step S604, the GK determines that the registration with the GW is successful, and then sets the relay state with the GW as norma...

Abstract

This provides a trunk test method used in relay test among soft switch networks including the following steps: updating the state of each relay dynamically and setting it normal and abnormal according to its state, in which, the soft switch network includes H.323, the relay is H.323 gateway relay connected between the first and the second soft switches. This invention also provides a relay test device.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a relay detection method and device. Background technique [0002] Each softswitch can manage a certain area. When it is necessary to realize mutual communication in a larger area, a method in the prior art is to use a relay to connect each softswitch, so that different areas can communicate with each other. Realize mutual communication to form a larger softswitch network. [0003] The relay is used to connect two identical networks (for example, two H.323 networks or two SS7 networks), and the cascading function of the softswitch network can be realized through the relay. In short, each softswitch manages a certain area, and then connects each softswitch with a relay. [0004] Involving the networking of multiple softswitches, multiple trunks can be configured between two softswitches. If a call needs to be connected to another softswitch, you can choose any trunk be...
