In embodiments of the present invention, since call request follows view networking protocol, association, which turns server, to incite somebody to action Call request is converted to the first call signaling for following RAS agreement, so that first call signaling can pass in internet It is defeated.

Step 503, when the destination address in the first call signaling is under targeted internet terminal connecting wan state When address, destination address is converted into the address under targeted internet terminal connection local net state, obtains the second call signaling.

Wherein, destination address refers to IP (Internet Protocol, Internet protocol) address.

In embodiments of the present invention, it is mesh that it is corresponding, which to turn the destination address in the first call signaling that server receives, for association Mark internet terminal corresponds to the destination address of wide area network, and targeted internet terminal is in local area network, it is therefore desirable to by destination Location is converted to the IP address that targeted internet terminal corresponds to local area network, obtains the second call signaling, can just make the second calling Signaling can send the targeted internet terminal in local area network.

Step 504, the second call signaling is sent to targeted internet terminal.

In embodiments of the present invention, association turn server can be according to the IP address in the second call signaling, by call request It is sent to the targeted internet terminal in local area network.

Step 505, it receives targeted internet terminal and is directed to the response signaling that the second call signaling is replied.

In embodiments of the present invention, targeted internet terminal can receive the second calling letter that association turns server transmission It enables, and response signaling can be generated for second call signaling, which follows call acceptance status protocol, then may be used Association is sent to so that signaling will be replied and turns server, association turns server then and can receive the response signaling.Wherein, response signaling can To include role identification, IP address port numbers, the call number of target view networked terminals of targeted internet terminal in a call The information such as alias and protocol version.

It step 506, is the call signaling for following view networking protocol by response Signalling conversion.

Wherein, the signaling for following view networking protocol can only be identified depending on networked terminals due to target, association turns server and exists It can be the calling sound for following view networking protocol by response Signalling conversion after receiving the response signaling for following Internet protocol Answer signaling.

Step 507, call signaling is sent to view networked server, so as to believe call depending on networked server Order is sent to target view networked terminals, when target receives call signaling depending on networked terminals, passes sequentially through view the Internet services Device and association turn server, carry out call operation to targeted internet terminal.

In embodiments of the present invention, association, which turns server, can be sent to call signaling view networked server, depending on connection Call signaling can be sent to target view networked terminals by network server in turn, and target can be received depending on networked terminals The call signaling, so far, target regard networked terminals and turn server to view networked server, then to association, and then mutual to target The communication channel of networked terminals is successfully established.Then, target can interconnect target by the communication channel depending on networked terminals Network termination carries out call operation.

Embodiment two

Fig. 6 is a kind of method flow diagram of calling Internet terminal provided by Embodiment 2 of the present invention, is applied to association and turns clothes Business device, it includes client modules and server module that association, which turns server, and client modules are connected with server module, such as Fig. 6 institute Show, this method comprises:

Step 601, the first virtual terminal of corresponding view networking is configured in client modules, and in server module Configure the second virtual terminal of corresponding internet.

It in embodiments of the present invention, may include two network interface cards since association turns server itself, one is that can join with view The view networking network interface card that net equipment is communicated is connect, the other is can interconnect with target with client modules depending on networking network interface card The internet network interface card that network termination is communicated, internet network interface card are connect with server module.It configures and corresponds in client modules It is exactly to be associated with the IP address of view networking network interface card with corresponding program, and target is regarded and is joined depending on the first virtual terminal networked The IP address of network termination is bound with the first virtual terminal.Second that corresponding internet is configured in server module is virtual whole End, be exactly the IP address of internet network interface card is associated with corresponding program, and by the IP address of targeted internet terminal and Second virtual terminal is bound.
