Step 602, association turns first invitation request turn of the server by the internet protocol-based after IP address conversion Change the second invitation request based on view networking protocol into.

Association turns server and depending on being based on interacting depending on networking protocol between networked server, therefore association turns server for IP The first invitation request of internet protocol-based after address conversion is converted into inviting based on the second meeting depending on networking protocol It please request.

In the implementation, association turns after server parses the first invitation of internet protocol-based request, by it The IP address of middle carrying replaces with corresponding view networking number, is then based on and is packaged depending on networking protocol to it, is based on The second invitation depending on networking protocol is requested.Second invitation request carries view networking number (including prefix number).

Step 603, association turns the action type that server determines the second invitation request.

Association turns there are many request types that server receives, therefore association turns server and obtaining based on view networking protocol After second invitation request, the action type of the second invitation request can also be determined.

In a kind of optional embodiment, association turns the step that server determines the action type of the second invitation request It suddenly include: that the association turns server and extracts view networking number from second invitation request, the view is networked number It include prefix number in code；The association turns server according to the corresponding relationship of preset prefix number and action type, searches institute The corresponding action type of prefix number is stated, the operation class that the action type found is requested as second invitation Type.

Prefix number depending on including in networking number is determined for action type.Can preset prefix number with The corresponding relationship of action type is simultaneously stored in association and turns in server.For example, it is meeting that prefix number, which is 91 corresponding action types, It invites, prefix number is that 60 corresponding action types are that meeting, etc. is added.Association turns server from the second invitation request View networking number is extracted, and extracts prefix number from depending on networking number, then searches the corresponding action type of prefix number, i.e., For the action type of the second invitation request.

Step 604, association turns server after determining that the action type is invitation, will be described based on view networking association The second invitation request of view is sent to the corresponding view networking of the view networking number eventually depending on networked server via described End.

Association turns server after determining that the action type of the second invitation request is invitation, can will be based on view The second invitation request of networking protocol is sent to view networked server, then via view networked server from based on view networking association The the second invitation request kind discussed parses the view networking number wherein carried, will be based on view networking association according to depending on networking number The second invitation request of view is respectively sent to the corresponding view networked terminals of each view networking number.

It, can be according to the corresponding view networked terminals of view networking number depending on networked server in a kind of optional embodiment The downstream communications link of configuration will be sent to view networked terminals based on the second invitation request depending on networking protocol.
