Abstract
The invention relates to a multichannel conversation fast-switching method based on a VoIP (Voice over Internet Phone) system. The multichannel conversation fast-switching method comprises the following steps of: establishing a fixed voice channel first, when the VoIP system calls out a conversation, distributing the established voice channel for the conversation, and when the VoIP system calls out another conversation, pausing the conversation which is being performed, and distributing the established voice channel for the conversation which is called out later, so that the voice channel begins to make service for the conversation which is called out later; and if a multi-party conversation instruction of the system is triggered, adding each paused conversation to the multi-party conversation by the system, establishing a new voice channel, and after the multi-part conversation is ended, destroying the newly established voice channel and reserving the former established voice channel by the system. The multichannel conversation fast-switching method has the capability of avoiding repeatedly establishing the voice channels and connecting hardware equipment for multiple times in the process of switching multiple conversations, thereby accelerating the voice conversation establishing time and improving the system resource utilization ratio.
Description
Technical field
The present invention relates to IP phone (VoIP) technical field, particularly relate in a kind of VoIP system the fast switch over method of multi-way call.
Background technology
VoIP(Voice over Internet Protocol), be with simulated sound signal (Voice) digitlization, do real-time transmission with the form of data packet (Data Packet) at IP data network (IP Network).IP phone, i.e. Internet Protocol telephone, its advantage is the telephone calling service that provides relatively inexpensive, and easily serves integratedly with internet multimedia, so IP phone is just obtaining using more and more widely.In traditional IP phone, system can set up a unique voice channel for each time caller or called service, be used for the transmitting-receiving of digital voice data, voice channel will link to each other with codec, finish encoding and decoding, after audio mixing equipment and DA conversion, analog audio data is sent to the electroacoustic equipments such as loud speaker.This just means, words are carried out if there is a-road-through in system, wants to switch to other a-road-through words, just must first the voice channel of conversing be disconnected and being connected of codec, and creates new voice channel again, and the connection codec.This multi-way call changing method, on the one hand can in creating voice channel and the process that is connected hardware device, waste the too much time, on the other hand, for all creating voice channel, each road conversation can consume too much system resource, the consequence that directly causes is that resource utilization is low, affects the user and experiences.
In view of this, the inventor furthers investigate for the defective of prior art, and has this case to produce.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of multi-way call fast switch over method based on VoIP, can be in the process of switching multi-way call, avoid repeating to create voice channel and repeatedly connecting hardware device, thereby accelerate voice call settling time, improve resource utilization ratio.
The present invention is achieved in that
A kind of multi-way call fast switch over method based on VoIP system comprises the steps:
Step 1: system's operation that powers on after hardware device is ready, creates one road fixing voice channel, and is connected with codec in the described hardware device; At this moment, this voice channel does not carry out transfer of data; Described hardware device comprises codec, mixer and DA transducer;
Step 2: when system's exhalation a-road-through words, i.e. during caller, be the voice channel that creates in this conversation allocation step 1, after this moment, voice channel received the configuration information of this road conversation, begin to carry out transfer of data; Wherein, described configuration information comprises calling IP address, codec type, Acoustics Parameters and RTP header packet information;
Step 3: system's other a-road-through words of breathing out; At this moment, suspend ongoing conversation, and before the configuration information of ongoing conversation be saved in the system, be the voice channel that creates in that road conversation allocation step 1 of breathing out afterwards simultaneously, this voice channel begins to be that road session services of exhalation afterwards; If system's another road conversation that begins again to breathe out this moment, then repeating step 3; Otherwise change step 4 over to;
Step 4: if recover the conversation be suspended, then to from system, take out the configuration information of preserving, and the voice channel of establishment in the configuration information write step 1;
Step 5: if the MPTY order of system is triggered, then system can join the conversation that each road is suspended in the MPTY;
The concrete steps that one tunnel conversation that is suspended joined MPTY are: create a road new voice channel, for this voice channel connects codec, taking-up is suspended the configuration information of conversation, this configuration information is write new voice channel, and the new voice channel in this road links to each other with codec, and speech data is by after decoding, can be in mixer carry out audio mixing with the speech data of other conversations, behind the DA transducer, electroacoustic equipment can play out sound, thereby realizes MPTY;
Step 6: when MPTY finished, the new voice channel that creates in the step 5 was destroyed by system, and deletion is the configuration information of correspondence with it, and kept the voice channel that creates in the step 1; A-road-through words as system breathes out new again then change step 2 over to.
Called situation is consistent with the caller situation.
The invention has the advantages that: can in switching the process of multi-way call, avoid repeating to create voice channel and repeatedly connecting hardware device, thereby accelerate voice call settling time, improve resource utilization ratio, reduce enterprise's production cost, accelerate system response time, Improving The Quality of Products.
Description of drawings
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is key step schematic diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of multi-way call fast switch over method based on VoIP system comprises the steps:
