In order to solve the problem that external voice equipment in an FTTR or a PON cannot access a PSTN, the application provides a method for accessing the external voice equipment based on the FTTR or the PON to the PSTN, and the method is applied to gateway equipment of the FTTR or the PON. The following description is made for some simple descriptions of application scenarios applicable to the technical solutions of the embodiments of the present application, and it should be noted that the application scenarios described below are only used for illustrating the embodiments of the present application and are not limiting. In the specific implementation process, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.
Referring to fig. 1, a schematic application scenario is provided in an embodiment of the present application, where the application scenario includes an external voice device, an FTTR/PON gateway, a VoIP server, a media gateway, and a PSTN.
The external voice equipment refers to equipment with entertainment function and conversation function, such as intelligent sound box equipment, and the external voice equipment can be connected to an FTTR/PON gateway, namely an FTTR or PON gateway equipment. The gateway device plays a role of a bridge connecting the user side and the optical fiber network side in the FTTR or PON network, so that the user can obtain high-speed broadband access and other communication services through the optical fiber network. The FTTR/PON gateway is connected to a VoIP server, which is a server for providing an internet-based voice communication service, which implements telephone calls and other voice communication functions by converting voice data into digital signals and transmitting them through the internet.
The VoIP server is connected to a media gateway, which is a network device for connecting different types of communication networks, allowing interworking and switching between the different networks. The media gateway is connected to the PSTN, which is a global telephone network used mainly for traditional voice communications, and is a circuit-switched network that establishes a dedicated communication channel (or circuit) for making calls between two telephone subscribers, which is the original, most widely used form of telephone network. The PSTN has access to both residential and mobile telephone user terminals.
It should be noted that, fig. 1 is an example of hanging an external voice device under the FTTR/PON gateway, and the number of external voice devices is not limited in practice. Fig. 1 illustrates two terminals, i.e., a residential user and a mobile phone user, connected to the PSTN, and is not limited in number.
The application scenario of the embodiment of the present application is introduced above, and the method for accessing the external voice equipment based on FTTR or PON shown in fig. 2 to the PSTN is described below with reference to the application scenario of fig. 1.
S201, an internal protocol signaling sent by external voice equipment is received.
The internal protocol signaling is converted by the external voice device according to the voice command and the device information of the external voice device, for example, (JavaScript Object Notation, JSON), (Type-Length-Value, TLV), and JSON is a lightweight data exchange format, which represents structured data in a text form easy to read and write, and performs data exchange between various programming languages. The TLV is a data encoding format that divides data into three parts, i.e., type, length, and value, and combines them in a specific format so that the receiving party can properly parse and process the data. The voice command is used to dial a target terminal in the PSTN, which may be a residential, commercial, government and public agency, mobile telephone user, international user, etc. terminal in the PSTN. The device information is used for uniquely identifying the position of the external voice device, and the device information comprises an IP address and a port number.
In the implementation process, a user wants to dial a target terminal in the PSTN network, and can say that: after receiving the voice command of the user, the external voice device firstly converts the voice command into an internal protocol signaling (JSON/TLV) and then sends the internal protocol signaling (JSON/TLV) to the gateway device in the FTTR or PON, so that the gateway device receives the internal protocol signaling sent by the external voice device.
S202, converting the internal protocol signaling into target protocol signaling.
The target protocol signaling is protocol signaling for implementing VoIP communication, such as session initiation protocol (Session Initiation Protocol, SIP), H248.SIP is an application-layer control protocol for setting up, modifying and terminating multimedia sessions (e.g., voice calls, video calls, etc.), and h.248 is a protocol for controlling a media gateway for controlling the media gateway to ensure proper transmission and management of media streams.
In the specific implementation process, the external voice equipment and the gateway equipment of the FTTR/PON realize independent protocols based on non-SIP/H248, the internal protocol signaling may be data in JSON or TLV format, the gateway equipment can directly analyze the data of the internal protocol signaling, and then the data is inserted into the original function of the voice application layer management module of the gateway equipment in a function interface mode, so that the target protocol signaling is generated.
Considering that the method of directly inserting function interfaces needs to insert more function interface processing logic in the original voice framework, which is not beneficial to the later maintenance. Thus, in one possible embodiment, a virtual digital signal processing (Digital Signal Processing, DSP) mechanism is designed, comprising the following steps:
analyzing the internal protocol signaling to obtain a voice instruction; generating an operation instruction of external voice equipment according to the voice instruction; converting the operation instruction into a virtual DSP event; and generating a target protocol signaling according to the DSP event.
In a specific implementation process, the external voice equipment can operate by using operation instructions such as off-hook, on-hook, answering, refusing, dialing and the like. The voice command and the operation command are corresponding, for example, the voice command is "make a call", the operation command is an off-hook call operation, for example, the voice command is "hang-up", and the operation command is an on-hook operation.
For example, DSP events corresponding to respective operation instructions are shown in table 1.
TABLE 1
For example, if the voice command received by the external voice device is "dial xx", the corresponding operation command is a LOCAL off-hook call operation, the LOCAL off-hook call operation is converted into a virtual DSP event (ext_local_call), and the virtual DSP event (ext_local_call) and the original DSP event (ext_local_call) are processed in the same manner, so as to generate the target protocol signaling.
In the embodiment of the application, a function interface penetration mode is not adopted, but a virtual DSP mechanism is redesigned, and the mechanism constructs the operations of off-hook, on-hook, answering, refusing, dialing and the like of the external voice equipment into virtual DSP events, so that the virtual DSP events and the original DSP events are processed identically, and the change of the original processing framework can be reduced.
And S203, the target protocol signaling is sent to the VoIP server through a voice channel, so that the VoIP server sends the target protocol signaling to the media gateway.
In one possible embodiment, the gateway device may parse the internal protocol signaling to obtain the IP address and the port number of the external voice device; determining a target voice channel from a plurality of voice channels according to the IP address and the port number of the external voice equipment; and sending the target protocol signaling to the VoIP server through the target voice channel.
Because the gateway device of the FTTR/PON contains multiple types of channels such as data and voice, the data traffic of the down-hook device of the gateway device defaults to data traffic, and cannot be forwarded through the voice channel. Therefore, in the embodiment of the present application, the target voice channel is determined according to the IP address and the port number of the external voice device, and the target protocol signaling can be sent to the VoIP server through the target voice channel.
Further, after receiving the target protocol signaling, the VoIP server sends the target protocol signaling to the media gateway, and the media gateway is configured to convert the target protocol signaling into PSTN signaling, so that the external voice device and the target terminal perform a voice call. PSTN Signaling such as Signaling System 7 (SS 7), SS7 is a communication protocol used for Signaling and switching in telephone networks.
Considering that the gateway device may have a plurality of external voice devices suspended from it, in one possible embodiment, the gateway device pre-stores a plurality of policy routing tables, each policy routing table being used to indicate a routing relationship between each external voice device and a voice channel. The gateway device can judge whether the plurality of policy routing tables comprise the policy routing table of the external voice device according to the IP address and the port number of the external voice device; if not, selecting an idle voice channel from the voice channels as a target voice channel.
In a specific implementation process, after the gateway device obtains the IP address and the port number of the external voice device, sequentially searching a plurality of pre-stored policy routing tables, if the IP address and the port number of the external voice device are not searched, determining that the plurality of policy routing tables do not include the policy routing table of the external voice device, and selecting an idle voice channel from the plurality of voice channels as a target voice channel.
In one possible embodiment, after selecting the idle voice channel from the plurality of voice channels as the target voice channel, the gateway device may further create a policy routing table of the external voice device according to the IP address and the port number of the external voice device and the IP address and the port number of the target voice channel.
In the implementation process, since the gateway device can hang down the voice device and other non-voice devices, after the gateway device obtains the IP address and the port number by analyzing the internal protocol signaling, the gateway device performs matching, determines that the IP address and the port number belong to the voice device, and MARKs the external voice device with a custom MARK (MARK), for example, 0x70, through the iptables MARK function, thereby ensuring that only the data stream of the external voice device is marked.
Further, since the gateway device has a plurality of voice channels, and performs routing by using a policy routing method, a policy routing table based on Firewall Mark (fwmark) matching can be created for a limited period, and the fwmark value is also 0x70. And creating a default route in the policy routing table, wherein the default route is used for sending out the signaling and voice data streams of the external voice equipment through a designated voice channel. And a return route can be created in the policy routing table, and the return route is used for forwarding the signaling and voice data stream received by the appointed voice channel to the external voice equipment.
In the embodiment of the application, when the policy routing table of the external voice equipment does not exist in the gateway equipment, the policy routing table of the external voice equipment is created, and when the subsequent gateway equipment receives the data traffic of the external voice equipment, the data traffic of the external voice equipment can be directly forwarded according to the policy routing table.
In one possible embodiment, after the gateway device determines whether the plurality of policy routing tables include the policy routing table of the external voice device according to the device information of the external voice device, if so, determining a target voice channel corresponding to the external voice device according to the policy routing table of the external voice device.
Further, after the gateway device determines the target voice channel, the source address and the source port number of the target protocol signaling may be converted from the IP address and the port number of the external voice device to the IP address and the port number of the target voice channel through a source address conversion (Source Network Address Translation, SNAT) function in the iptables, so that the target protocol signaling is sent to the VoIP server through the target voice channel.
In this embodiment of the present application, the gateway device may convert, through the SNAT function, a source IP address and a source port number of a signaling and data flow sent by the external voice device into an IP address and a port number of a voice channel of the FTTR/PON gateway, and may also convert, subsequently, a destination address and a destination port number of a signaling and data flow sent by the VoIP server into an IP address and a port number of the external voice device.
In an actual network, the IP address of the voice channel may not be unique, and after the gateway device is restarted or the lease of the IP address of the voice channel expires, the IP address of each voice channel may be updated, so that the IP address of each voice channel may be monitored in real time, and the IP addresses of the target voice channels in the policy routing tables may be updated in real time.
Considering that the real-time monitoring and real-time updating processes are complicated, in one possible embodiment, if the gateway device is restarted or the lease of the IP address of the target voice channel expires, automatically acquiring the IP address of the external voice device, and converting the source address of the target protocol signaling from the IP address of the external voice device to the IP address of the target voice channel; and sending the target protocol signaling to the VoIP server through the target voice channel.
In a specific implementation process, an address MASQUERADE (MASQUERADE) function of iptabs is used, and MASQUERADE is a special case of source address translation (Source Network Address Translation, SNAT), so that an automatic SNAT function can be implemented, and an IP address of a specified network card can be automatically acquired and source address translation can be implemented.
In order to more clearly illustrate the method for accessing the external voice equipment to the PSTN based on the FTTR or the PON, the whole flow of accessing the external voice equipment to the PSTN is introduced.
S1.1, the user informs the external voice equipment through a voice instruction, such as dialing other mobile phone users.
S1.2, the external voice equipment converts the voice instruction into an internal protocol signaling (JSON/TLV) and sends the internal protocol signaling (JSON/TLV) to gateway equipment of the FTTR/PON.
S1.3, gateway equipment of the FTTR/PON converts internal protocol signaling (JSON/TLV) into SIP/H248 protocol signaling through the method provided by the embodiment of the application, and then sends the SIP/H248 protocol signaling to a VoIP server of an operator through a voice channel.
S1.4, the VoIP server sends the SIP/H248 protocol signaling to the media gateway.
S1.5, the media gateway converts the SIP/H248 protocol into PSTN signaling (such as SS 7) and performs signaling negotiation with other PSTN subscribers.
S1.6, after the negotiation is completed, starting to perform normal voice call.
In summary, the embodiments of the present application provide a method for accessing an external voice device to a PSTN based on FTTR or PON, which converts signaling and data flow of external voice into signaling and data flow of SIP/H248 in an FTTR/PON gateway, thereby solving the problem that external voice device in FTTR or PON cannot access to PSTN. The user can not only communicate with the PSTN through the customized external voice equipment, but also use the entertainment function of the external voice equipment. Because the manual off-hook key is not needed, the operation is only needed through the voice instruction, the physical limitation of the telephone line in the house is broken through, and the telephone can be dialed at will. And simultaneously, the utilization rate of the voice service of the operator is improved.
