Step S201: exchange of speech server 103 with the communications connection procedure of recipient 102, judges whether calling party 101 and recipient 102 are positioned at same local area network (LAN) in calling party 101; If so, then step S202 is performed; Otherwise, the transmission of the VoIP communicating data bag between calling party 101 and recipient 102 is carried out according to art methods.
Particularly, exchange of speech server 103 sets up calling party 101 and the communications connection procedure of recipient 102, can comprise: calling party 101 sends call request to exchange of speech server 103; Exchange of speech server 103 according to the information of recipient in call request 102, to recipient 102 forwarded call request; Recipient 102 can return ringing information to exchange of speech server 103, and answers information to exchange of speech server 103 transmission after answering the call; After exchange of speech server 103 receives the information of answering, set up the communication connection between recipient 101 and calling party 102.
In fact, exchange of speech server 103 can in calling party 101 with the communications connection procedure of recipient 102, according to the wide area network information of calling party 101 and recipient 102, as IP information, calling party 101 and recipient 102 can be determined whether not in same local area network (LAN).Such as, when calling party 101 is positioned at mobile network, and recipient 102 is when being positioned at UNICOM's network, exchange of speech server 103 can be easy to determine that calling party 101 and recipient 102 be not in same local area network (LAN), now, exchange of speech server 103 can send the announcement information of wan communication directly to calling party 101 and/or recipient 102.Like this, after calling party 101 and/or recipient 102 receive the announcement information of wan communication, directly according to art methods, the transmission of the VoIP communicating data bag between calling party 101 and recipient 102 can be carried out based on wide area network.
When exchange of speech server 103 can not determine that calling party 101 and recipient 102 be not in same local area network (LAN), the call request that exchange of speech server 103 can send from calling party 101, parse the LAN Information of calling party 101; And answer information from what send after recipient 102 answers the call, parse the LAN Information of recipient 102; Exchange of speech server 103, according to the LAN Information of calling party 101 and recipient 102, determines whether calling party 101 and recipient 102 are positioned at same local area network (LAN).
Step S202: exchange of speech server 103 sends the announcement information of local area network communication to calling party 101 and recipient 102.
Particularly, if exchange of speech server 103 judges that calling party 101 and recipient 103 are arranged in same local area network (LAN), then send the announcement information of local area network communication to calling party 101 and recipient 102, start calling party 101 and communicate based on the VoIP of local area network (LAN) with recipient 102.Wherein, the announcement information of local area network communication is used to indicate calling party 101 and/or recipient 102 transmits VoIP communicating data bag by local area network (LAN) to the other side.
Thus, after calling party 101 or recipient 102 receive announcement information, transmit VoIP communicating data bag by local area network (LAN) to the other side.
In actual applications, according to the LAN Information of calling party 101 and recipient 102, exchange of speech server 103 judges whether calling party 101 and recipient 102 are positioned at same local area network (LAN), situation about judging by accident may be there is, that is, may occur that exchange of speech server 103 judges that calling party 101 and recipient 102 are positioned at same local area network (LAN), and in fact calling party 101 and recipient 102 are not positioned at the situation of same local area network (LAN).
More preferably, occur for avoiding this kind of situation, when calling party 101 and/or recipient 102 receive the announcement information of the local area network communication that exchange of speech server 103 sends, also send our LAN IP address, listening port and Token (token) information newly produced by exchange of speech server 103 to the other side; Like this, the other side uses the Token received to connect LAN IP address and the listening port of we, if on can connecting in setting-up time section, then both sides carry out the transmission of VoIP communicating data bag based on local area network (LAN), realizes P2P call.Wherein, the length of setting-up time section can be set according to the actual requirements by those skilled in the art.
Thus, the judgement whether calling party 101 and recipient 102 are positioned at same local area network (LAN) is successively carried out by exchange of speech server 103, calling party 101 and/or recipient 102, the accuracy judged can be ensured, thus ensure the normal talking between calling party 101 and recipient 102.
The flow chart of the VoIP communication means based on local area network (LAN) that the embodiment of the present invention one provides, also as shown in Figure 2 b, can comprise the following steps S221 to step S223:
Step S221: communication terminal is communicated to connect by exchange of speech server 103 and opposite end.
Particularly, communication terminal can be specifically above-mentioned calling party 101, also can be recipient 102.Wherein, when communication terminal is calling party, its opposite end is recipient; When communication terminal is recipient, its opposite end is calling party.
Step S222: communication terminal sends the LAN Information of this communication terminal to exchange of speech server 103, so that exchange of speech server 103 judges whether this communication terminal and opposite end are arranged in same local area network (LAN).
Particularly, after communication terminal sends the LAN Information of this communication terminal to exchange of speech server 103, judge whether this communication terminal and opposite end are arranged in same local area network (LAN) by exchange of speech server 103.
Step S223: the announcement information of the local area network communication that communication terminal sends according to exchange of speech server 103, based on local area network (LAN) to opposite end transmission VoIP communicating data bag.
Wherein, the announcement information of described local area network communication is, interactive voice server 103, in the communications connection procedure of communication terminal and opposite end, after judging that communication terminal and opposite end are arranged in same local area network (LAN), sends to communication terminal and/or opposite end.
Below by introducing calling party, mutual between recipient and exchange of speech server in detail, the VoIP communication means of the embodiment of the present invention one is described.Particularly, the schematic flow sheet of the VoIP communication means based on local area network (LAN) of the embodiment of the present invention one, as shown in Figure 2 c, comprises the steps that S211 is to step S217:
Step S211: calling party 101 sends call request to exchange of speech server 103.
In this step, calling party 101 sends call request by wide area network to exchange of speech server 103.
Step S212: exchange of speech server 103 is to recipient 102 forwarded call request.
In this step, exchange of speech server 103 resolves the call request that calling party 101 sends, and obtains the information of recipient 102, according to the information obtained to the recipient 102 forwarded call request in wide area network.
Step S213: recipient 102 sends to exchange of speech server 103 and answers information.
In this step, recipient 102 presses Answer Key, during the calling of the side of answering the call 101, sends answer information to exchange of speech server 103.In addition, as mentioned above, before information is answered in transmission, recipient 102 also can send ringing information to exchange of speech server 103.
If recipient 102 is hung up or the calling of the side of not answering the call 101, the information refusing to answer or do not answer then is sent to exchange of speech server 103, exchange of speech server 103 does not set up both communication connections, and the notice of answering or not answering can be refused to calling party 101 transmission and reception side 102, sign off.
Step S214: exchange of speech server 103 sets up the communication connection of calling party 101 and recipient 102.
In this step, what exchange of speech server 103 received that recipient 102 sends answers information, and set up the communication connection of calling party 101 and recipient 102, namely calling party 101 and recipient 102 connect and converse.
The communication connection of calling party 101 and recipient 102 can be set up by above-mentioned steps S211 to S214.In fact, in the process of the communication connection of calling party 101 and recipient 102, judge whether calling party 101 and recipient 102 are arranged in same local area network (LAN) by following step S215 to S217, determine the transmission how carrying out VoIP communicating data bag.
Step S215: exchange of speech server 103 judges whether calling party 101 and recipient 102 are positioned at same local area network (LAN); If so, then step S216 is performed; Otherwise, the transmission of the VoIP communicating data bag between calling party 101 and recipient 102 is carried out by existing method.
In this step, exchange of speech server 103 judges whether calling party 101 and recipient 102 are positioned at the method for same local area network (LAN), with reference to described in above-mentioned steps S201, can repeat no more herein.
Wherein, if calling party 101 and recipient 102 are not positioned at same local area network (LAN), exchange of speech server 103 carries out VoIP communication by wide area network.
Step S216: exchange of speech server 103 sends the announcement information of local area network communication to calling party 101 and the side of answering 102.
Step S217: calling party 101 and recipient 102 are based on local network transport VoIP communicating data bag.
In this step, calling party 101 and recipient 102 are by both residing local network transport VoIP communicating data bags.Such as, calling party 101 and recipient 102 are connected in same wifi (Wireless Fidelity), then transmit VoIP communicating data bag by wifi, call speed and the rapid-result positive correlation of wifi network.
More preferably, calling party 101 or recipient 102 are after transmitting VoIP communicating data bag by local area network (LAN) to the other side, when determining the speech quality of communication link of local area network (LAN), during speech quality lower than the communication link of wide area network, being switched to wide area network and transmitting VoIP communicating data bag to the other side.Thus in a local network disconnected or local area network (LAN) is poor especially time, ensure that calling party and recipient still can carry out normal talking by wide area network.Such as, suppose such scene, after company personnel A and B carries out VoIP call, use the wifi network of company to converse, when employee A leaves company in communication process, switch to wide area network and carry out VoIP call.
Wherein, speech quality specifically can be determined according to following index: the RTT value (Round-Trip Time, round-trip delay) of communication link and/or packet loss.And, when according to the RTT value of communication link and packet loss determination speech quality, the equilibrium strategy between RTT value and packet loss can be set, namely the weight of RTT value and packet loss is set when determining speech quality.
In fact, while calling party 101 transmits VoIP communicating data bag by local area network (LAN) to the other side with recipient 102, exchange of speech server 103 keeps and the connection of calling party 101 with recipient 102, and, calling party 101 and recipient 102 can send heartbeat packet to exchange of speech server 103, obtain current RTT value; Further, calling party 101 and recipient 102 also can send the VoIP communicating data bag setting quantity, with the packet loss of test network every setting-up time section to exchange of speech server 102.
Such as, RTT value between calling party 101 and exchange of speech server 103 is a, RTT value between recipient 102 and exchange of speech server 103 is b, RTT value between calling party 101 and recipient 102 is c, if a+b<c, then calling party 101 or recipient 102 determine the speech quality of the communication link of local area network (LAN), lower than the speech quality of the communication link of wide area network, now local area network (LAN) are switched to wide area network and transmit VoIP communicating data bag to the other side.
For another example, packet loss between calling party 101 and exchange of speech server 103 is e, packet loss between recipient 102 and exchange of speech server 103 is f, is that e and f show that calling party 101 and recipient 102 are g by the packet loss of wide area network transmission VoIP communicating data bag according to packet loss; And calling party 101 and recipient 102 are h by the packet loss of local network transport VoIP communicating data bag, if g<h, then calling party 101 or recipient 102 determine the speech quality of the communication link of local area network (LAN), lower than the speech quality of the communication link of wide area network, now local area network (LAN) is switched to wide area network and transmits VoIP communicating data bag to the other side.
In fact, calling party 101 or recipient 102 can also every setting-up time sections, the speech quality of the speech quality of the communication link of local area network and the communication link of wide area network compares, and determines to use local area network (LAN) or wide area network transmits VoIP communicating data bag according to comparative result.
The internal structure block diagram of the communication terminal (calling party 101 or recipient 102) that the embodiment of the present invention one provides, as shown in Figure 5, comprises communication connection module 501 and local speech communication module 502.
