Description

Implementation Method of Call Pickup Service Based on Internet Voice Gateway

technical field

The invention relates to a method for realizing the call pickup service in a communication system, in particular to a method for realizing the call pickup service based on an Internet voice gateway.

Background technique

With the development of Internet technology, realizing the function of Internet telephony on Internet routers can enable users to complete the transmission of voice information by means of data communication networks, effectively improve the utilization rate of data networks, and increase the types of services provided by the network. Therefore, people It is expected that intelligent voice services, such as call pickup service, can be realized in the network. According to the existing implementation method of calling services based on network voice gateways, when a communication device A, such as a telephone, initiates a call request to the voice gateway 1 connected to it, the voice gateway 1 detects the call request of the user, and sends the call request to the voice gateway 1. The signal is transmitted to the voice processing module on the upper layer of the voice gateway 1, and the voice processing module plays a prompt dial tone to the communication device A through the gateway device. After the user enters the destination address information, the information is collected and stored by the voice gateway 1. When the voice gateway 1 After collecting destination address information that can match a destination address, query the corresponding destination IP address according to the destination address information, and use this IP address to initiate an IP call connection to the peer voice gateway 2. When voice gateway 2 receives voice gateway 1 After the call is initiated, a call is initiated to the called communication device B according to the destination address information, and if the called communication device is idle, it will notify that a call request has arrived, otherwise it will feed back the called busy information to the voice gateway 1. In the actual application of the voice gateway, there is such a situation. For example, when phone A calls phone B, if phone B is idle, phone B rings to indicate that a call arrives, but if there is no answer at phone B at this time, and There is someone A on duty at phone C. If A wants to answer phone B, he needs to go to phone B to answer. If A is far away from phone B, it will take a certain amount of time to walk to phone B. During this time, use phone A users may hang up the phone at any time, resulting in the connection failure of this call. Under the above circumstances, from the perspective of the basic call process of the existing Internet phone, the function of person A at phone C to answer phone B at phone C cannot be realized, which may lead to communication failure.

Contents of the invention

The purpose of the present invention is to provide a method for realizing the call pickup service based on the Internet voice gateway that can realize the call pickup.

In order to achieve the above object, the implementation method of the call pickup service based on the Internet voice gateway provided by the present invention includes:

Step 1: The user equipment sends a call request to the voice gateway connected to it;

Step 2: The voice gateway judges according to the received call request. If the request is a call pickup request, the voice gateway judges whether there is a call from the pickup device. If not, end the operation, otherwise complete the call from the pickup device transfer.

When the voice gateway determines in step 2 that the received call request is another operation, it completes the corresponding operation according to the request.

Since the present invention can realize the call pickup service by utilizing the hardware and operating system characteristics of the voice gateway itself on the basis of ensuring the basic call connection of the voice gateway, it can not only complete the basic communication function of the voice gateway, but also make a call that may fail It is connected by another communication device, thereby reducing the possibility of communication failure and expanding the application range of the voice gateway.

Fig. 2 is a schematic diagram of the principle of the present invention.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

In order to solve the communication failure problem caused by the unattended communication equipment called and the nearby communication equipment being on duty but not answering the unattended communication equipment in time, the current call pickup method can be used to solve the problem caused by the unattended communication equipment. Communication failure problem. Taking Figure 2 as an example, when there is a call to called communication device B, if the called communication device B is not answered at this time, communication device C can be used to pick up the call for communication device B to prevent this communication Failed, this solves the problem of communication failure caused by unattended called equipment. As shown in Figure 2, when communication device A initiates a call to communication device B connected to the network, it first connects to voice gateway 2 through voice gateway 1, and then connects to communication device B through voice gateway 2. If no one answers communication device B, then Communication device C answers the phone call of communication device B through the call pickup service.

Fig. 1 is a flowchart of an embodiment of the method of the present invention. According to Fig. 1, the present invention mainly includes the processing of call pickup requests. The voice gateway described in the embodiment shown in Fig. 1 is not only limited to the voice gateway in practice, but also can be any equipment that provides VoIP (VOIP/VOFR) services, such as equipment that includes a network phone call control function module, and this equipment can Provides the ability to detect dual-tone multi-frequency (DTMF) numbers, so that when the communication device that initiates a call outputs a DTMF number, the recognized DTMF number is sent to the voice gateway for processing, and the VoIP call control function module of the voice gateway The DTMF number received can complete the request for call pickup, thereby completing the operation specified by the user.

When the user initiates a call request to the voice gateway connected to it through the calling device in step 1, the voice gateway that receives the request judges the nature of the request according to the call request input by the user. If the request is an operation other than call pickup, Then complete the corresponding operation in step 3; if the request is a call pickup request, then in step 4 judge whether the equipment corresponding to the pickup number exists and whether there is a call request to arrive, if any situation does not exist, then in step 5 to The user who initiates the call pickup responds with an operation error prompt; if there is a pickup device corresponding to this number and a call request arrives, then in step 6, the call is transferred to the pickup device according to the user's request. In the above step 6, it also includes judging the state of the device to be answered. If the device is idle or in a talking state, it will respond to the user who initiated the call pickup with an operation error prompt. Only when the device to be answered is in the vibration state When the ring indicator is in the state, the call to the picked-up device can be transferred to the device that initiates the call pickup to realize the call pickup service.

If a device connected to the voice gateway (assumed to be phone B, the number is ABCD), when a device connected to the voice gateway receives an IP phone call from the network side (assumed to be phone A), phone B When a call is received, it will ring to indicate that a call has arrived. At this time, if the operator of phone C wants to answer phone A, he can input "*51*ABCD#", where ABCD represents the phone B to be answered, and # represents the input end sign. The voice gateway device detects the "*51*ABCD#" number sequence input by the user, locates phone B according to the number ABCD, transfers the call to phone B to phone C, and restores phone B to its initial state.

Of course, the use of the call pickup service can also be registered in the voice gateway first, and then used, which depends on the actual use needs. In a word, the device can provide call pickup service by adopting the present invention.
