Description

Voice gateway device and communication processing method of voice gateway

technical field

The embodiment of the present invention relates to the technical field of communication, and in particular to a voice gateway device and a communication processing method of the voice gateway.

Background technique

With the development of network technology, the voice service is gradually changing from traditional voice based on Circuit Switch (CS) domain to Voice over Internet Protocol (Voice over Internet Protocol) based on Packet Switch (PS) domain. Correspondingly, the fax service is gradually transitioning from analog fax in the traditional CS domain to IP-based network fax (Fax over IP, referred to as FoIP). Therefore, in the current communication network, voice/fax services in the CS domain and VoIP/FoIP in the PS domain will coexist for a long period of time. In response to this transitional situation, there are currently a variety of transitional voice terminal products that can simultaneously support voice/fax services in the CS domain and VoIP/FoIP services in the PS domain, typically voice gateway devices with routing switching functions .

In the prior art, there are generally two implementation schemes for this type of voice gateway device: the first scheme is realized by correspondingly configuring different preambles for different communication types of services. That is to say, in this solution, when the user dials, different preambles are added for different communication types in the CS domain or PS domain, and the voice gateway device starts the corresponding communication service processing process according to the obtained different preambles; The second solution is realized by adding an additional modulation and demodulation circuit, that is, in the voice gateway device, two modulation and demodulation circuits are respectively set for the two types of communication services, and the processing unit receives the information of the corresponding modulation and demodulation circuit. The communication data enters the corresponding communication service processing flow.

However, the inventor found in the process of realizing the present invention that each of the above two schemes has certain defects: for the first scheme, although the addition of the preamble can enable the voice gateway to distinguish services of different communication types, in this scheme, the voice The gateway device can only be set with one communication interface, and the addition of the preamble increases the complexity of the user's use, and the usability is poor, and this method needs to change the voice call processing flow and the entire system accordingly, which is very unfavorable for promotion. For the second scheme, two modulation and demodulation circuits are set up in the voice gateway for the two types of data communication, which is equivalent to adding an additional modulation and demodulation circuit on the basis of the original single modulation and demodulation scheme. The circuit supports two types of communication services at the expense of cost, which is also not an optimal implementation solution.

Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Fig. 1 is a schematic structural diagram of a voice gateway device provided by an embodiment of the present invention. As shown in Fig. 1, the voice gateway device of this embodiment includes: two RJ11 interfaces 1, a modulation and demodulation circuit 2, and a The processing unit 3 to which the circuit 2 is connected. Wherein, the two RJ11 interfaces 1 correspond to CS domain communication services or PS domain communication services respectively, that is, for a single RJ11 interface, the RJ11 interface or terminal equipment dedicated to CS domain communication services, such as traditional telephone-based Network telephones and fax machines, or terminal equipment dedicated to PS domain communication services, such as VoIP telephones and FoIP fax machines based on IP networks. Moreover, a level detection circuit 4 is provided between each RJ11 interface 1 and the processing unit 3 , and a switch circuit 5 is provided between each RJ11 interface 1 and the modulation and demodulation circuit 2 .

Specifically, for each level detection circuit 4, the level detection circuit 4 is connected with the corresponding RJ11 interface 1 and the processing unit 3, when the corresponding RJ11 interface 1 is in the off-hook or on-hook state, the level detection The circuit 4 will output signals of different levels to the processing unit 3 according to the detected state. In addition, for each switch circuit 5, the switch circuit 5 is connected to the corresponding RJ11 interface 1 and the modulation and demodulation circuit 2, and the control terminal of the switch circuit 5 is connected to the processing unit 3, when the processing unit 3 outputs different levels When the control signal is received, the switch circuit 5 will be opened or closed accordingly under the control of the control signal, so that the communication link between the modulation and demodulation circuit 2 and the corresponding RJ11 interface 1 is also on or off accordingly. broken state.

Specifically, the processing unit 3 controls the opening or closing of the switch circuit arranged between the RJ11 interface 1 and the modulation and demodulation circuit 2 according to the detection and identification of a certain situation, so that the corresponding RJ11 interface 1 and the modulation and demodulation circuit 2 The communication link between them is turned on or off, and the data processing flow of which communication service should be entered is determined according to the detection or identification result. In this embodiment, the processing unit 3 will control the switch circuit 5 between the RJ11 interface 1 and the modulation and demodulation circuit 2 to be in a conducting state under the following two situations.

The first case applies when the terminal device connected to the voice gateway device is on the calling side. Specifically, when the processing unit 3 detects that the RJ11 interface 1 connected to the level detection circuit 4 is in the off-hook state through any level detection circuit 4, it is known that the voice terminal equipment connected to the RJ11 interface 1 will initiate 1. Communication business. Therefore, in order to enable the voice terminal equipment to transmit data to the peer terminal, it can be transmitted to the modulation and demodulation circuit 2 through the RJ11 interface 1 for modulation and demodulation processing, and then the processing unit 3 can transmit the processed communication data via wired or Send it wirelessly to the peer terminal in this communication service, and in order to enable the processing unit 3 to receive the communication data sent by the peer terminal through the modulation and demodulation circuit 2 and through the RJ11 interface during this communication process 1 to the connected voice terminal equipment, at this time, the processing unit 3 will control the switch circuit 5 corresponding to the RJ11 interface 1 to close, so that the communication link between the corresponding RJ11 interface 1 and the modulation and demodulation circuit 2 is turned on, and The switch circuit 5 connected to the other RJ11 interface 1 is controlled to be turned on, so that the communication link between the other RJ11 interface 1 and the modulation and demodulation circuit 2 is turned off. Therefore, the voice terminal device connected to the turned-on RJ11 interface 1 can perform voice or fax service data communication with the opposite terminal through the RJ11 interface 1 and the voice gateway device.

Further, in this embodiment, each RJ11 interface 1 corresponds to a specific type of communication service, that is, a CS domain communication service or a PS domain communication service. Therefore, in order to make the processing unit 3 control and turn on the communication link between the corresponding RJ11 interface 1 and the modulation and demodulation circuit 2, in the subsequent processing of the communication data of the voice terminal equipment connected to the RJ11 interface 1, According to the communication service type of the voice terminal equipment, enter the corresponding data processing flow process, and the processing unit 3 will also start the corresponding data processing flow process according to the communication service type corresponding to the RJ11 interface 1, so that the processing unit receives the communication After receiving the data, it can enter the corresponding data processing flow corresponding to the type of the communication data, and perform corresponding data processing on the communication data.

The second case applies when the voice terminal connected to the voice gateway is on the called side. Specifically, when the processing unit 3 receives the incoming call data sent by the peer terminal in a wired or wireless manner, it will first identify the data service type of the incoming call data, so as to identify that the incoming call data is service data belonging to the CS domain Or service data in the PS domain. Since the communication services of the CS domain and the PS domain, the network types carried and transmitted by these two communication services are different, so the data format of the incoming call data will also be different, and the processing unit 3 passes the data format of the incoming call data. The identification of the communication service type of the incoming call data is obtained, and then the RJ11 interface 1 corresponding to the incoming call can be identified. Therefore, in order to enable the voice terminal equipment connected to the corresponding RJ11 interface 1 to perform data communication with the opposite terminal, the processing unit 3 controls the switch circuit 5 corresponding to the RJ11 interface 1 to close according to the recognized result, so that the corresponding RJ11 interface The communication link between 1 and the modulation and demodulation circuit 2 is in a conducting state, and the switch circuit 5 connected to the other RJ11 interface 1 is controlled to open, so that the communication between the other RJ11 interface 1 and the modulation and demodulation circuit 2 The link is down. Thus, the data output by the processing unit 3 through the modulation and demodulation circuit 2 can be transmitted to the connected voice terminal equipment through the conducting RJ11 interface 1 .

Further, in order to enable the processing unit 3 to control and turn on the communication link between the corresponding RJ11 interface 1 and the modulation and demodulation circuit 2, in the subsequent processing of the communication data of the terminal equipment connected to the RJ11 interface 1, it can According to the communication service type corresponding to the voice terminal device, enter the corresponding data processing flow. The processing unit 3 will also start the corresponding data processing process according to the identified communication service type, so that the processing unit can enter the corresponding data processing process after receiving the communication data in the communication service, so as to receive The received communication data is processed accordingly.

In this way, through the separate control of the voice gateway device in the incoming call or outgoing call state by the processing unit, there is no need to add preambles for various types of communication services, and no need to add an additional modulation and demodulation circuit. The voice gateway device can also support two communication service types at the same time through the level detection circuit and switch circuit correspondingly set for each RJ11 interface, and can enter the corresponding communication data according to the intelligent identification of the two communication service types. data processing unit for processing.

This embodiment provides a voice gateway device. By setting a detection circuit for each interface and setting a switch circuit between each interface and the modulation and demodulation circuit, only the processing unit detects the off-hook state of the corresponding interface through the detection circuit. , or in the process of being called, when the processing unit recognizes that the incoming call data received is the communication service type corresponding to the interface, it controls to open the switch circuit between the corresponding interface and the modem circuit, and enters into the corresponding data processing process, so that the voice gateway device can realize simultaneous support for CS domain communication services and PS domain communication services without adding an additional modem circuit and under the premise that users do not need to add preambles for different data service types , reduces the cost and is easy to use and easy to promote.

FIG. 2 is a schematic structural diagram of another voice gateway device provided by an embodiment of the present invention. As shown in FIG. 2 , on the basis of the previous embodiment, in the voice gateway device of this embodiment, the processing unit 3 may include: a first control unit 31 and a second control unit 32 . The first control unit 31 further includes: a detection subunit 311 , a first switch control subunit 312 , a query subunit 313 and a first promoter unit 314 .

Specifically, the input end of the level detection circuit 4 is connected to the TIP pin of the corresponding RJ11 interface 1 (not shown in the figure), the output end is connected to the processing unit 3, and the level detection circuit 4 is used for Different levels of the TIP pins output detection signals of different levels to the processing unit 3 . The detection subunit 311 is used to detect the level of the TIP pin of the RJ11 interface 1 corresponding to the level detection circuit 4 through the detection signal output by the level detection circuit 4 . Specifically, for an RJ11 interface, there are generally two pins inside it: a TIP pin and a RING pin. During the calling process, when the voice terminal equipment connected to the RJ11 interface is in a different state, the level of the TIP pin will change: when the voice terminal equipment is in the on-hook state, the level of the TIP pin is low. When the voice terminal equipment is in the off-hook state, the level of the TIP pin will be a negative high voltage level of about -50V. And because the level detection circuit 4 is connected with the TIP pin corresponding to the RJ11 interface, and can output detection signals of different levels according to the level change of the connected TIP pin, therefore, according to the obvious TIP pin on the RJ11 interface The detection subunit 311 can detect the off-hook and on-hook states of the corresponding RJ11 interface through the level detection circuit.

The first switch control subunit 312 is used to control the corresponding RJ11 interface when the detection subunit 311 detects that the TIP pin of the corresponding RJ11 interface is a negative high-voltage level, that is, when it detects that the RJ11 interface is in the off-hook state. The switch circuit connected to the above-mentioned RJ11 interface is turned on, and the switch circuit connected to the other RJ11 interface is controlled to be turned off. Specifically, when detecting the off-hook state of the RJ11 interface, the first switch control subunit 312 sends a corresponding control signal to the switch circuit to turn on and off the switch circuit. For example, in this embodiment, when the first switch control subunit 312 needs to turn on the corresponding switch circuit, it outputs a control signal of the first level to the switch circuit, and the control signal of the switch circuit at the first level Under the action of the signal, it will be in a closed state, so that the communication link between the corresponding RJ11 interface and the modulation and demodulation circuit is turned on, and when the first switch control subunit 312 needs to turn off another switch circuit, the output The control signal of the second level is given to the switch circuit, and the switch circuit will be in an open state under the action of the control signal of the second level, so that the communication link between the other RJ11 interface and the modulation and demodulation circuit Road shut down.

In addition, the query subunit 313 is used to query the communication service type of the corresponding RJ11 interface after controlling the corresponding switch circuit to be turned on, that is, to query whether the corresponding RJ11 interface is a CS domain communication service type or a PS domain communication service type. communication service type; and the first starting subunit 314 is used to start the corresponding data processing unit according to the communication service type of the corresponding RJ11 interface inquired by the query subunit 313, so as to enter the corresponding data processing flow.

Further, the first control unit 31 may also include a second switch control subunit 315, which is used to control the corresponding The switch circuit connected to the RJ11 interface is turned off, and the switch circuit connected to the other RJ11 interface is controlled to be turned on. Similarly, when the second switch control subunit 315 detects the on-hook state of the RJ11 interface, it can also turn off the switch circuit by sending a corresponding control signal to the switch circuit. Specifically, in this embodiment, when the second switch control subunit 315 needs to turn off the corresponding switch circuit, it outputs a control signal of the second level to the switch circuit, and the switch circuit at the second level Under the action of the control signal, it will be in an open state, so that the communication link between the corresponding RJ11 interface and the modulation and demodulation circuit is shut down, and at the same time, the second switch control subunit 315 outputs a control signal of the first level to another The switch circuit, the other switch circuit is in a closed state under the action of the control signal of the first level, so that the communication link between the corresponding RJ11 interface and the modulation and demodulation circuit is turned on.

In addition, in this embodiment, the second control unit 32 in the processing unit 3 may include: an identification subunit 321 , a third switch control subunit 322 , a second promoter subunit 323 and a sending subunit 324 . Wherein, the identifying subunit 321 is used to identify whether the received incoming call data belongs to the CS domain communication service or the data belonging to the PS domain communication service; the third switch control subunit 322 is used to identify whether the incoming call data is When the data of the CS domain communication service type is used, the control signal of the first level is output to the switch circuit connected to the RJ11 interface corresponding to the CS domain communication service, so that the switch circuit is turned on, and if the incoming call data is identified as PS When the data of the domain communication service type is used, a control signal of the first level is output to the switch circuit connected to the RJ11 interface corresponding to the PS domain communication service, so that the switch circuit is turned on. The second starting subunit 323 is configured to start a corresponding data processing flow according to the communication service type of the incoming call data identified by the identifying subunit 321 .

The sending subunit 324 is used to send the incoming call indication information to the modulation and demodulation circuit according to the communication service type of the incoming call data identified by the identification subunit 321, so that the modulation and demodulation circuit can control the transmission through the third switch control subunit 322. The switched circuit is turned on to output an incoming call signal to the RJ11 interface corresponding to the communication service type identified by the identification subunit 321, so that the voice terminal connected to the RJ11 interface generates a ringing signal.

Specifically, in this embodiment, the level detection circuit 4 and the switch circuit 5 can be realized by certain components. For example, the working principle of the level detection circuit 4 is to output detection signals of different levels to the first switch control subunit in the processing unit according to the level of the TIP pin on the corresponding RJ11 interface. Therefore, in practical applications, the level detection circuit 4 can be realized by a triode or an optocoupler device. As for the switch circuit 5, its working principle is to be in an open or closed state according to the control signals of different levels output by the processing unit, so that the communication link between the corresponding RJ11 interface and the modulation and demodulation circuit is turned on or shut down. Therefore, in practical applications, the switch circuit 5 can be realized by a switch tube or a relay.

FIG. 3 is a schematic circuit diagram of a level detection circuit and a switch circuit in the voice gateway device according to the embodiment of the present invention. In FIG. 3 , taking the level detection circuit as a transistor and the switch circuit as a switch as an example, the partial circuit structure of the voice gateway device in this embodiment is described. Specifically, as shown in FIG. 3 , the transistor Q1 and the resistors R1 to R5 are part of the level detection circuit, and the switch tubes Q2 and Q3 and the resistors R6 and R7 are part of the switch circuit. Wherein, the input end of the level detection circuit is connected to the TIP pin of the corresponding RJ11 interface, and the output end is connected to the GPIO1 pin of the processing unit; the input and output ends of the switch circuit are respectively connected to the TIP pin of the corresponding RJ11 interface and the processing unit. The unit is connected, and the control terminal is connected to the GPIO2 pin of the processing unit.

When the RJ11 interface is in the off-hook state, the TIP signal input by the TIP pin is a negative high level, the transistor Q1 is turned on, and the detection signal on the GPIO1 pin of the processing unit is low level, the processing unit detects this signal and knows The off-hook state of the corresponding RJ11 interface, so the signal of the control terminal GPIO2 of the switch circuit connected to the RJ11 interface is set to a high level, and the switch tube Q2 is cut off under the action of the high level of GPIO2, thereby together with the TIP signal The conduction of the switch tube Q3 is controlled, so that the switch circuit is in a conduction state. For another RJ11 interface, because in this embodiment, the switch circuit is in the off state by default, that is, the signal default state of the control terminal GPIO2' (not shown in the figure) of another switch circuit The low level state of the lower bit, so the processing unit does not need to do any processing on the control terminal GPIO2' of another switch circuit.

When the RJ11 interface is in the on-hook state, the TIP signal input by the TIP pin is low level, the transistor Q1 is cut off, the detection signal on the GPIO1 pin of the processing unit is high level, the processing unit detects this signal, and knows the corresponding In the on-hook state of the RJ11 interface, the signal of the control terminal GPIO2 of the switch circuit connected to the RJ11 interface is set to a low level, and the switch tube Q2 is turned on under the action of the low level of GPIO2, thereby controlling the switch together with the TIP signal The cut-off of the tube Q3 makes the switch circuit in the cut-off state.

FIG. 4 is a schematic circuit diagram of another level detection circuit and switch circuit in the voice gateway device according to the embodiment of the present invention. In FIG. 4 , the partial circuit structure of the voice gateway device in this embodiment is described by taking the level detection circuit as an optocoupler device and the switch circuit as a relay as an example. Specifically, as shown in FIG. 4 , the optocoupler D1, resistors R1 and R2 are part of the level detection circuit, and the relay D2, transistor Q1 and resistors R3, R4 and R5 are part of the switch circuit. Wherein, the input end of the level detection circuit is connected to the TIP pin of the corresponding RJ11 interface, and the output end is connected to the GPIO1 pin of the processing unit; the input and output ends of the switch circuit are respectively connected to the TIP pin of the corresponding RJ11 interface and the processing unit. The unit is connected, and the control terminal is connected to the GPIO2 pin of the processing unit. In the default state, both relays are on.

When the RJ11 interface is in the off-hook state, current flows through the TIP pin and the control terminal of the optocoupler device D1, then the sensing terminal of D1 is in the conduction state, the detection signal on the GPIO1 pin of the processing unit is low level, and the processing unit This signal is detected, and the off-hook state of the corresponding RJ11 interface is known. Because in this embodiment, the default state of the switch circuit is a conduction state, the processing unit does not need to perform control processing on the RJ11 interface that is detected to have an off-hook state. , just set the signal of the control terminal GPIO2' of the switch circuit connected to the other RJ11 interface to a high level, so that the triode Q1' of the other switch circuit is cut off under the action of the high level of GPIO2', thus The relay D2' for controlling the other switch circuit is turned on so that the switch circuit on the other RJ11 interface is in the off state (not shown in the figure).

When the RJ11 interface is in the on-hook state, there is no current passing through the TIP pin and the control terminal of the optocoupler device D1, then the sensing terminal of D1 is in the cut-off state, the detection signal on the GPIO1 pin of the processing unit is high level, and the processing unit detects After receiving this signal, the on-hook state of the corresponding RJ11 interface is known, so the signal of the control terminal GPIO2 of the switch circuit connected to the RJ11 interface is set to a high level, and the triode Q1 is cut off under the action of the low level of GPIO2. Therefore, the cut-off of the relay D2 is controlled, so that the switch circuit is in a cut-off state.

It should be noted that, in the embodiment of the present invention, only the level detection circuit is a transistor or an optocoupler device, and the switch circuit is a switch tube or a relay as an example. The circuit has been described, but it should be understood that other implementations with the same functions as the above-mentioned level detection circuit and switch circuit can also be applied to the voice gateway device in the embodiment of the present invention, and are also implemented in the present invention. within the scope of protection.

In the voice gateway device of this embodiment, by correspondingly setting a detection circuit for each interface, and setting a switch circuit between each interface and the modulation and demodulation circuit, only the processing unit detects the off-hook state of the corresponding interface through the detection circuit, or In the process of being called, when the processing unit recognizes that the incoming call data received is the communication service type corresponding to the interface, it controls to open the switch circuit between the corresponding interface and the modulation and demodulation circuit, and enters the corresponding data processing flow, In this way, the voice gateway device can support CS domain communication services and PS domain communication services at the same time without adding an additional modulation and demodulation circuit, and users do not need to add preambles for different data service types, reducing Cost-effective and easy to use, easy to promote.

FIG. 5 is a flowchart of a communication processing method of a voice gateway provided by an embodiment of the present invention. As shown in Figure 5, the method includes the following steps:

Step 100, if the processing unit of the voice gateway detects that the RJ11 interface is in the off-hook state through the level detection circuit arranged between the processing unit and any RJ11 interface in the two RJ11 interfaces, the control is set on the RJ11 interface The switching circuit between the modulation and demodulation circuit is turned on, and according to the communication service type of the RJ11 interface, the data processing process corresponding to the communication service type is started;

Specifically, in this embodiment, the two RJ11 interfaces of the voice gateway respectively correspond to communication services in the CS domain and communication services in the PS domain. Moreover, a level detection circuit is provided between any RJ11 interface of the two RJ11 interfaces and the processing unit, for outputting detection signals of different levels according to the off-hook or on-hook status of the corresponding RJ11 interface. At the same time, a switch circuit is provided between any RJ11 interface and the modulation and demodulation circuit, the control end of the switch circuit is connected to the processing unit, and is used to open or close accordingly under the control of the control signal output by the processing unit state, so that the communication link between the modulation and demodulation circuit and the corresponding RJ11 interface is also in the on or off state accordingly.

Specifically, when the voice gateway is on the calling side, when the processing unit detects that the RJ11 interface connected to the level detection circuit is in an off-hook state through any level detection circuit, it knows that the voice signal connected to the RJ11 interface is in the off-hook state. The terminal device will initiate a communication service. Therefore, in order to enable the voice terminal device to perform data communication with the opposite terminal in this communication service, the processing unit 3 will control the switch circuit corresponding to the RJ11 interface to close, so that the connection between the corresponding RJ11 interface and the modulation and demodulation circuit The communication link is on. Therefore, the voice terminal device connected to the RJ11 interface can perform voice or fax service data communication with the opposite terminal through the RJ11 interface and the voice gateway device.

Further, in order to enable the processing unit to control and turn on the communication link between the corresponding RJ11 interface and the modem circuit, in the subsequent processing of the communication data of the voice terminal equipment connected to the RJ11 interface, according to the voice The communication service type of the terminal equipment enters the corresponding data processing flow flow, and the processing unit will also start the corresponding data processing flow according to the communication service type corresponding to the RJ11 interface, so that the processing unit can enter the corresponding data processing flow after receiving the communication data. In the corresponding data processing flow corresponding to the type of the communication data, corresponding data processing is performed on the communication data.

Step 101, the processing unit identifies the communication service type of the received incoming call data, and starts the corresponding data processing flow according to the identified communication service type, and controls the connection to the RJ11 interface corresponding to the identified communication service type The switch circuit is turned on.

When the voice gateway is located on the called side, when the processing unit receives the incoming call data sent by the peer terminal through wired or wireless means, it first identifies the data service type of the incoming call data to identify whether the incoming call data belongs to The service data of the CS domain or the service data of the PS domain. By identifying the data format of the incoming call data, the processing unit knows the communication service type of the incoming call data, and then can identify the RJ11 interface corresponding to the incoming call. Therefore, in order to enable the voice terminal equipment connected to the corresponding RJ11 interface to perform data communication with the peer terminal, the processing unit controls the switch circuit corresponding to the RJ11 interface to close according to the recognized result, so that the corresponding RJ11 interface and modem The communication link between the circuits is in a conducting state, so that the data output by the processing unit through the modulation and demodulation circuit can be transmitted to the connected voice terminal equipment through the corresponding RJ11 interface.

Step 200, the processing unit of the voice gateway detects the off-hook or on-hook state of the corresponding RJ11 interface through the level detection circuit, if the off-hook state is detected, enter step 201, and if the on-hook state is detected, enter step 203;

Step 201, the processing unit controls the switch circuit provided between the RJ11 interface and the modulation and demodulation circuit to be turned on;

Step 202, the processing unit starts a data processing flow corresponding to the communication service type according to the detected communication service type of the RJ11 interface in the off-hook state;

Step 203, the processing unit controls the switching circuit arranged between the RJ11 interface and the modulation and demodulation circuit to be turned off;

Specifically, the input end of the level detection circuit is connected to the TIP pin of the corresponding RJ11 interface, and the output end is connected to the processing unit. When the RJ11 interface is in different states, the level of the signal output by the TIP pin will be different. Specifically, if the RJ11 interface is in the on-hook state, the level of the TIP pin is low; and if the RJ11 interface is in the off-hook state, the level of the TIP pin will be a negative high voltage level of about -50V. The level detection circuit will output detection signals of different levels to the processing unit under the action of different levels of the TIP pin. The processing unit can detect the off-hook or on-hook state of the corresponding RJ11 interface according to the difference in the detection signal level output by the level detection circuit.

Specifically, if the processing unit detects that the corresponding RJ11 interface is in the off-hook state through a level detection circuit, the processing unit controls the switch circuit provided between the RJ11 interface and the modulation and demodulation circuit to conduct, and queries the detected The communication service type of the RJ11 interface in the off-hook state, and according to the queried communication service type, start the data processing flow corresponding to the communication service type pair. If the processing unit detects that the corresponding RJ11 interface is in the on-hook state through a level detection circuit, the processing unit will control the switch circuit arranged between the RJ11 interface and the modulation and demodulation circuit to turn off.

Step 205, the processing unit controls the switch circuit connected to the corresponding RJ11 interface to be turned on according to the identified communication service type;

Step 206, the processing unit sends incoming call indication information to the modulation and demodulation circuit;

In step 207, the processing unit starts a corresponding data processing flow according to the identified communication service type.

However, when the voice gateway in this embodiment is on the called side, in this embodiment, after receiving the incoming call data sent by the peer terminal, the voice gateway identifies the communication service type of the incoming call data, that is, identifies whether the incoming call data belongs to The CS domain communication service still belongs to the data of the PS domain communication service, so as to determine the RJ11 interface corresponding to the incoming call.

The demodulation circuit sends corresponding incoming call indication information. Since the communication link between the modem circuit and the RJ11 interface of the CS domain communication service is turned on, the incoming call signal sent by the modem circuit will be transmitted to the connected voice terminal equipment through the RJ11 interface, so that Ringing occurs on the connected voice end device. Next, the processing unit starts a data processing flow corresponding to the communication service in the CS domain, so that in this communication process, corresponding processing can be performed on the communication data belonging to the CS domain.

On the contrary, if the processing unit recognizes that the communication service type of the incoming call data is the data of the PS domain communication service through the identification of the incoming call data, the processing unit will control the RJ11 interface and the modulation and demodulation circuit corresponding to the PS domain communication service. The conduction of the switch circuit set between them, and send the corresponding incoming call indication information to the modulation and demodulation circuit. Since the communication link between the modem circuit and the RJ11 interface of the PS domain communication service is turned on, the incoming call signal sent by the modem circuit will be transmitted to the connected voice terminal equipment through the RJ11 interface, so that the Ringing occurs on the connected voice end device. Next, the processing unit starts a data processing flow corresponding to the PS domain communication service, so that in this communication process, corresponding processing can be performed on the communication data belonging to the PS domain.

Specifically, in this embodiment, the level detection circuit arranged between the RJ11 interface and the processing unit can be realized by a triode or an optocoupler device, and the switch circuit 4 can be realized by a switch or a relay.
