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 by simulated sound signal (Voice) digitlization, with the form of data packet (Data Packet), on IP data network (IP Network), do real-time transmission.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 applying more and more widely.In traditional IP phone, system can be set up a unique voice channel for caller or called service each time, transmitting-receiving for digital voice data, voice channel will be connected with codec, complete 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, if system has a-road-through, words are carried out, and wants to be switched to other a-road-through words, just must be first by being connected of the voice channel disconnection of conversing and codec, then create new voice channel, and connect codec.This multi-way call changing method, on the one hand can in creating voice channel and being connected the process of hardware device, waste the too much time, on the other hand, for all creating voice channel, each road call can consume too much system resource, the consequence directly causing is that resource utilization is low, affects user and experiences.
In view of this, the inventor furthers investigate for the defect 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 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.
The present invention is achieved in that
A multi-way call fast switch over method based on VoIP system, comprises the steps:
Step 1: the system operation that powers on, after hardware device is ready, creates the fixing voice channel in a road, and be connected with the codec in described hardware device; Now, this voice channel does not carry out transfer of data; Described hardware device comprises codec, mixer and DA transducer;
Step 2: when system exhalation a-road-through words, i.e., during caller, be the voice channel creating in this call allocation step 1, now voice channel receives after the configuration information of this road call, starts 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: the system other a-road-through words of breathing out; Now, suspend ongoing call, and the configuration information of ongoing call is before saved in system, be the voice channel of establishment in the Na road call allocation step 1 of breathing out afterwards simultaneously, and this voice channel starts as breathing out afterwards Na road session services; If now system another road call that starts again to breathe out, repeating step 3; Otherwise proceed to step 4;
Step 4: if recover the call be suspended, to from system, the configuration information of preserving be taken out, and the voice channel of establishment in configuration information write step 1;
Step 5: if the MPTY order of system is triggered, the call that system can be suspended each road joins in MPTY;
The concrete steps that the call that Jiang Yi road is suspended joins MPTY are: create Xin mono-road voice channel, for this voice channel connects codec, taking-up is suspended the configuration information of call, this configuration information is write to new voice channel, and the new voice channel in this road is connected with codec, and speech data is by after decoding, can in mixer, carry out audio mixing with the speech data of other calls, after DA transducer, electroacoustic equipment can play out sound, thereby realizes MPTY;
Step 6: when MPTY finishes, system is destroyed the new voice channel creating in step 5, deletes corresponding with it configuration information, and retains the voice channel creating in step 1; A-road-through words as system is breathed out new again, proceed to step 2.
Called situation is consistent with 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.
Accompanying drawing explanation
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.
