The exchange method flow chart of a kind of Media Stream that Fig. 3 provides for the embodiment of the present invention.This embodiment Executive agent is the network equipment, which describes in detail that voice exchange carries out voice communication at calling terminal Time make Media Stream mutual between calling terminal and terminal called by the side that is transmitted, IP address set Method.Wherein, the network equipment can be specifically voice exchange.As it is shown on figure 3, the present embodiment include with Lower step:

Step 301, the network equipment receives the signaling message of transmission between calling terminal and terminal called.

When calling terminal initiates audio call to terminal called, the net between calling terminal and terminal called Network equipment will receive signaling message.This signaling message can carry the mark of calling terminal and/or called The mark of terminal.

Wherein, when calling terminal sends signaling message to terminal called, this network equipment can be and master It is the voice exchange that terminal is connected, when terminal called sends signaling message to calling terminal, this net Network equipment can be the voice exchange being connected with terminal called.It should be noted that calling terminal and Terminal called can be connected on same voice exchange, it is also possible to is connected to different voices and hands over On changing planes.

Step 302, the described network equipment judges, according to described signaling message, the media that described signaling message is corresponding Whether stream packet is configured to the internet protocol address transmission set, and described IP address is institute State the IP address of the network equipment.

According to signaling message, the network equipment judges whether media stream message is configured to the IP address set The concrete operation method of transmission can be, the mark of the calling terminal included according to described signaling message or The mark of terminal called judges whether the media stream message that described signaling message is corresponding is configured to set IP address transmission；Or, judge, according to the source of described signaling message, the matchmaker that described signaling message is corresponding Whether body stream packet is configured to the IP address transmission set.

Specifically, the mark of the calling terminal that signaling message includes can be calling terminal IP address, The number etc. of calling terminal, judges, according to the mark of calling terminal, the Media Stream report that described signaling message is corresponding The IP address whether literary composition is configured to set is transmitted specifically, query configuration information table, it is judged that Whether the address field at the IP address of calling terminal or the place, IP address of calling terminal is configured with the IP of setting Address；And judge whether the media stream message that described signaling message is corresponding is joined according to the number of calling terminal It is set to be transmitted specifically, query configuration information table by the IP address set, it is judged that calling terminal Whether the number end at the number place of number or calling terminal is configured with the IP address of setting.Same, letter The mark making the terminal called that message includes can be the IP address of terminal called, the number of terminal called Deng, judge whether the media stream message that described signaling message is corresponding is configured to according to the mark of terminal called It is transmitted specifically, query configuration information table by the IP address set, it is judged that the IP of terminal called Whether the address field at the place, IP address of address or terminal called is configured with the IP address of setting；And according to The number of terminal called judges whether the media stream message that described signaling message is corresponding is configured to set IP address be transmitted specifically, query configuration information table, it is judged that the number of terminal called or called end Whether the number segment at the number place of end is configured with the IP address of setting.

The source of signaling message can be trunking or subscriber terminal equipment, and the network equipment judges signaling Behind the source of message, can be according to this source, it is judged that whether the Media Stream that signaling message is corresponding is configured to From the IP address transmission set.

In order to realize technical scheme, in actual applications, in the configuration information table of the network equipment Save the mark of calling terminal and the mapping relations of the IP address set, and/or the mark of terminal called Mapping relations with the IP address set, it is also possible to preserve the source of signaling message and the IP address set Mapping relations.The network equipment can retrieve in this configuration information table when performing step 302 with main Cry the IP address of the mark correspondence of terminal and/or the IP address corresponding with the mark of terminal called, it is also possible to Retrieve the source of signaling message and the mapping relations of the IP address set.Certainly, this configuration information table is also Can be saved in other network entity, obtain the IP address corresponding with the mark of calling terminal at needs And/or with the IP address corresponding to mark of terminal called, or during the IP address of the source correspondence of signaling message, The network equipment can obtain automatically from other network entity.

Alternatively, the particular content of configuration information table can be updated according to actual networking requirement by user, Particularly as follows: receive, Media Stream corresponding to the terminal iidentification specified or the signaling message source specified is configured to The configuration message of the IP address transmission by setting；According to described configuration message, arrange described Media Stream It is configured through the configuration information of the IP address transmission set；Described configuration information is saved in described configuration In information table.

Specifically, for IP phone terminal, user can be according to actual networking requirement, in exchange of speech Carry out office on machine to setting, the signaling flow and Media Stream sent from calling terminal is set, and flows into caller The signaling flow of terminal and Media Stream all flow in and out from the IP address of the setting of voice exchange, and should Configuration is saved in configuration information table.Certainly, the signaling flow sent from terminal called can be set too And Media Stream, and the signaling flow of inflow terminal called and Media Stream are all from the IP of the setting of voice exchange Address flows in and out.Furthermore it is also possible to all IP phones being connected with this voice exchange are all joined It is set to the IP address from setting flow in and out.

Step 303, if it is, be sent to Calling Side equipment by the IP address of described setting so that described Calling Side equipment sends media stream message by the IP address of described setting to callee side equipment；And/or, The IP address of described setting is sent to described callee side equipment so that described callee side equipment is by described The IP address set sends media stream message to Calling Side equipment；Described Calling Side equipment is specially caller eventually Another network equipment between end or described calling terminal and the described network equipment, described callee side equipment has Body is another network equipment between described terminal called or described terminal called and the described network equipment.

Specifically, if Calling Side equipment or callee side equipment are connected by non-IP mode (such as narrow band fashion) To this network equipment, then this network equipment is without sending setting to this Calling Side equipment or callee side equipment IP address.

When calling terminal and terminal called are all directly connected on the network equipment, Calling Side equipment is main Being terminal, callee side equipment is terminal called.When calling terminal and terminal called are connected to caller language Sound switch is connected with called voice exchange, and when the network equipment is caller voice exchange, caller Side apparatus is calling terminal, and callee side equipment is another network between terminal called and the described network equipment Equipment, is called voice exchange.When calling terminal and terminal called respectively with caller voice exchange It is connected with called voice exchange, and when the network equipment is called voice exchange, Calling Side equipment is Another network equipment between calling terminal and the described network equipment, is caller voice exchange, called Side apparatus is then terminal called.

In the embodiment of the present invention, the network equipment receives the signaling of transmission between calling terminal and terminal called and disappears Breath；According to described signaling message, the described network equipment judges that the media stream message that described signaling message is corresponding is The no internet protocol address transmission being configured to set, described IP address is that described network sets Standby IP address；If it is, the IP address of described setting is sent to Calling Side equipment so that described Calling Side equipment sends media stream message by the IP address of described setting to callee side equipment；And/or, The IP address of described setting is sent to described callee side equipment so that described callee side equipment is by described The IP address set sends media stream message to Calling Side equipment；Described Calling Side equipment is specially caller eventually Another network equipment between end or described calling terminal and the described network equipment, described callee side equipment has Body is another network equipment between described terminal called or described terminal called and the described network equipment.By This, the embodiment of the present invention achieves Media Stream in voice call procedure and flows in and out from the IP address set, It is easy to the configuration of fire wall.

In conjunction with above-described embodiment, in a preferred embodiment, after step 303, Ji Jiangsuo Stating after the IP address of setting is sent to described Calling Side equipment, the network equipment is all right: set by described Fixed IP address receives the first media stream message that Calling Side equipment sends；To described first media stream message Carry out transcoding process, obtain the second media stream message that described terminal called can decode that；To described called Side apparatus sends described second media stream message.

And before by step 303, before the IP address that will set is sent to Calling Side equipment, network Equipment may further determine that existence carries out transcoding process and obtains the first internal media stream described first media stream message The first transcoding resource needed for message, and determine that described first internal media stream packet is carried out turning by existence Code processes the second transcoding resource obtained needed for described second media stream message.So, the network equipment just may be used By following step, the first media stream message carried out transcoding and process obtain that terminal called can decode that second Media stream message: use described first transcoding resource that described first media stream message is carried out transcoding process, Obtain described first internal media stream packet, and use described second transcoding resource to the described first internal matchmaker Body stream packet carries out transcoding process, obtains described second media stream message.

Same, at the network equipment, the IP address set is sent after callee side equipment, the network equipment All right: to receive, by the IP address of described setting, the 3rd media stream message that described callee side equipment sends； Described 3rd media stream message is carried out transcoding process and obtains the fourth media that described calling terminal can decode that Stream packet；Described fourth media stream packet is sent to described Calling Side equipment.

3rd media stream message just can be carried out transcoding process by following step and obtain caller eventually by the network equipment The fourth media stream packet that end can decode that: described 3rd media stream message is used described second transcoding money Source carries out transcoding process and obtains the second internal media stream packet, uses described second internal media stream packet Described first transcoding resource carries out transcoding process and obtains described fourth media stream packet.

Certainly, if voice exchange internal existence supports that the media stream message that calling terminal sends directly turns It is changed to the transcoding resource of the media stream message that terminal called can decode that, then can also carry out a transcoding, Directly carry out the media stream message after the encoding and decoding algorithm coding that calling terminal use is supported self and called end Mutual conversion between the media stream message that end can decode that.

By above-mentioned steps, to the media stream message interacted with calling terminal inside voice exchange With the Media Stream interacted with terminal called carries out Media Stream transcoding respectively, it is converted into internal general matchmaker Body stream, such as arrowband Media Stream, it is achieved Media Stream carries out transcoding in voice exchange.Thus, the present invention Embodiment can realize the encoding and decoding between calling terminal and terminal called need not have common factor can also complete language Sound is conversed.

In order to illustrate in greater detail the interaction of the Media Stream between calling terminal and terminal called, below By an embodiment, Media Stream between Calling Side equipment, the network equipment, callee side equipment is described mutual Method.Wherein, Calling Side equipment be specially calling terminal or described calling terminal and the described network equipment it Between another network equipment, callee side equipment is specially described terminal called or described terminal called with described Another network equipment between the network equipment, Calling Side equipment and callee side equipment are all straight with the network equipment Connect and be connected.The present embodiment is with the network equipment as voice exchange, and calling terminal and terminal called are all Being introduced as a example by being attached to the scene on this voice exchange, in this scenario, Calling Side equipment is Calling terminal, callee side equipment is terminal called, and the network equipment is voice exchange.Fig. 4 is the present invention The most mutual method flow diagram of a kind of Media Stream that embodiment provides.As shown in Figure 4, This embodiment comprises the following steps:

Step 401, calling terminal sends the signaling message of calling terminal called to voice exchange.

Calling terminal is when terminal called initiates audio call, and voice exchange will receive calling terminal and send out The signaling message sent, can carry the mark of calling terminal and/or the mark of terminal called in this signaling message Know.

Step 402, voice exchange judges whether calling terminal or terminal called require Media Stream and signaling flow Flow in and out from the IP address set.
