Description
Technical field
The present invention relates to communication technical field, particularly relate to method and device that a kind of voice home gateway side realizes internal call transfer.
Background technology
At present, internal and international voice transmission technology mainly comprises the transmission technology of transmission technology based on traditional PSTN (PSTN) network and IP based network, corresponding voice call type can divide in order to PSTN calling and VOIP calling (by the digitlization of simulated sound signal, doing the one calling of transmitting in real time with the form of data packet on IP data network).In addition, multiple FXS interface (user's Analog Trunk Interface on voice home gateway, for being connected to the such basic telephone equipment of phone, modulator-demodulator and fax) on the audio call of initiating by different extension between multiple common phones of being connected, we are referred to as internal call.
Along with developing rapidly of the communications industry, people are more and more not content with simple point to point call business, therefore based on SIP (SessionInitiationProtocol, Session Description Protocol) VOIP calling on many IMS (IPMultimediaSubsystem that emerged, IP multimedia system) business, the diversified speech business demand of present user can be met.The existing internal call transfer business based on IMS is realized by IMS service device completely, and IMS service device is essential, and forwarded user is also only limitted to VOIP user.
Summary of the invention
In view of above-mentioned analysis, the present invention aims to provide method and the device that a kind of voice home gateway side realizes internal call transfer, in order to solve the problem that the existing internal call transfer business based on IMS must be realized by IMS service device.

Embodiment
Specifically describe the preferred embodiments of the present invention below in conjunction with accompanying drawing, wherein, accompanying drawing forms the application's part, and together with embodiments of the present invention for explaining principle of the present invention.For purpose of clarity and simplification, when it may make theme of the present invention smudgy, illustrating in detail of known function and structure in device described herein will be omitted.
First, described in 1 and 2 pair of embodiment of the present invention, method is described in detail by reference to the accompanying drawings.
As shown in Figure 1, the application scenarios figure that Fig. 1 is method described in the embodiment of the present invention, comprises three terminals, terminal A, terminal B and terminal C respectively, wherein, terminal A and terminal C answers under belonging to the different FXS interfaces of same voice home gateway machine, and terminal B belongs to outside line terminal.
As shown in Figure 2, Fig. 2 is the schematic flow sheet of method described in the embodiment of the present invention, for convenience of description, only to carry out example alternately between three terminals in accompanying drawing 2, and example is not carried out for mutual between voice home gateway and three terminals, specifically can comprise the steps:
Step: 201: call out assuming that answer under a certain FXS interface that connects of voice home gateway machine (terminal A) and arbitrary outside line (terminal B) establish a road VOIP;
Step 202: if determine to need internal call transfer when terminal B and terminal A converses, to answer under being transferred to by terminal B and the call of terminal A another FXS interface that same voice home gateway is connected machine (terminal C), then terminal A presses flash button on phone or hooking, the voice home gateway voice module of voice home gateway (in particular, can be) sends the SIP signaling keeping terminal B to network side soft switching server;
After step 203: terminal B receives the SIP signaling that voice home gateway sends, feedback response message;
Step 204: voice home gateway, after receipts answer the response message of terminal B, puts dialing tone to terminal A, prompt terminal A answers under dialing the FXS interface of another free time of equipment machine (terminal C) different extension;
Step 205: terminal A has dialled terminal C number;
Step 206: voice home gateway sends Internal call signaling directly to terminal C;
Ring event and the off-hook event of step 207: terminal C report voice home gateway, and voice home gateway is communicated with the voice dsp passage between terminal A and terminal C;
Step 208: terminal A and C enters talking state;
Step 209: if terminal C agrees to converse with terminal B, then terminal A on-hook;
Step 210: voice home gateway notice is by relevant information (comprising give out a contract for a project information and media information) the notification terminal C of terminal A and terminal B call;
Step 211: voice home gateway sends the SIP signaling recovering outside line terminal B simultaneously to soft switch;
Step 212: terminal A discharges, and terminal B and terminal C enters call;
Describe in detail above by the flow process of third party's on-hook by calling access, below still using Fig. 1 as application scenarios, introduced the method for call denial.
After terminal A and terminal C set up call, recognize that terminal C will refuse converse with terminal B, then terminal A presses flash key or hooking, and terminal C listens on-hook after calling unlocking noise, the call between voice home gateway recovery terminal A and terminal B.
In addition, terminal C also initiatively can refuse the calling of terminal B, after terminal A and terminal C call, terminal C recognizes when having the calling of terminal B to access, can directly to access terminal the calling of B by on-hook refusal, now terminal A can directly on-hook, the call between voice home gateway release terminal A and terminal B, and terminal also can press the call that flash key or hooking recover between B.
Last device described in 3 pairs of embodiment of the present invention is by reference to the accompanying drawings described in detail.
As shown in Figure 3, Fig. 3 is the structural representation of device described in the embodiment of the present invention, and this device in voice home gateway, specifically can be able to comprise:
