Fixed telephones, called fixed telephones for short, commonly called fixed telephones, refer to telephones which are fixed at a certain position and do not move, are different from mobile telephones (mobile phones) and are mostly used in enterprise units, and fixed telephones are one of important communication means in modern times. Under the current large background of 'copper entering and exiting', part of commercial buildings and parks stop deploying telephone lines and only reserve network lines; in addition, because the analog phone has simple function and cannot meet the requirements of part of key government and enterprise clients on multimedia communication and high-quality voice of a fixed network terminal, the SIP (Session initiation Protocol) phone is inevitably popularized in a large scale in the scope of the government and enterprise large clients. With The advance of FTTH (Fibre To The Home) reconstruction, all fixed-line services are synchronously changed into SIP mode access at present, so that a fixed-line telephone is also one of SIP terminal equipment, communication is carried out based on The SIP fixed-line telephone, The current household broadband field is also in The process of 'optical access and copper withdrawal', The SIP telephone is a network using The Internet or other IP technologies, The SIP based on The IP protocol utilizes The IP network To realize novel telephone communication, and The application of transmitting voice information in real time on The Internet through The TCP/IP protocol is realized. The SIP telephone is mainly applied to the intranet of a large-scale company, and technicians can multiplex the same network to provide data and voice services, so that the management is simplified, and the productivity can be improved. SIP type home gateways have become widespread on a large scale. The initial SIP phone was a call between a personal computer and a personal computer, and both parties of the call installed a sound card and related software for their own devices and agreed to get on the internet at the same time to make the call, which is now commonly referred to as voice over internet chat. SIP phones can be divided into four types in form: PC-PC, phone-PC, PC-phone, phone-phone. The SIP phone is said to be a true SIP phone, i.e. a call from a normal phone to a normal phone is realized through the Internet.

The SIP protocol is an authentication verification mechanism, the SIP server authenticates the SIP terminal equipment through the SIP account and the password, and therefore if the SIP account and the password are stolen, the SIP server cannot verify the source of the SIP terminal, and the communication fault is easily caused.

To solve at least the above problems in the prior art, embodiments of the present application respectively propose a communication method of a fixed telephone, a communication apparatus of a fixed telephone, an electronic device, and a computer-readable storage medium, which will be described in detail below.

Referring to fig. 1, fig. 1 is a flowchart illustrating a communication method of a fixed-line telephone according to an exemplary embodiment of the present application, where the communication method of the fixed-line telephone provided by the present embodiment includes steps S100 to S300, and reference is made to the following steps for detailed description:

step S100: a first terminal device associated with fixed telephone number information is acquired.

In the present embodiment, the fixed telephone number information, that is, authentication information related to the fixed telephone number, for example, the fixed telephone number, the password, and the like, used for registering on the SIP server, since the communication process of the fixed telephone in the present embodiment is the fixed telephone number based on the SIP protocol, the fixed telephone number may also be the SIP account number. The authentication method for the SIP terminal specified in the SIP protocol is: when receiving an unauthenticated access request sent to the SIP terminal, the SIP server responds to a 401Unauthorized response to the SIP terminal, wherein the 401Unauthorized response comprises parameters such as realm, dynamic nonce, opaque, Algorithm and Qop; the SIP terminal device also generates a dynamic cnonce value when retrying to send the registration request, and calculates the digest authentication response by using the following algorithm: HA1 ═ md5("username: realm: passswerd"); HA2 ═ md5("method: uri") response ═ md5("HA1: nouce: nc: cnonce: qop: HA 2"); after receiving the registration request retransmitted by the SIP terminal, the SIP server needs to check the validity of the user name and the password. The SIP server uses the username and password already stored at the server in conjunction with other parameters in the message header field. The digest authentication response is calculated using the same digest authentication algorithm as the SIP terminal (e.g., MD5), and the calculation result is compared with the response value in the request digest. The key points of the authentication process are as follows: since the value of response is related to parameters such as user name, password, nonce, cnonce, algorithm, etc., both the SIP server and the SIP client can consider the other party as not fake if the results are consistent. Therefore, a great risk exists, if the SIP account and the password are leaked, the SIP account and the password can be stolen, the SIP server can not effectively distinguish which SIP terminal is illegally accessed, and the SIP account and the password can be stolen by lawbreakers. In this case, it is necessary to identify the correct terminal device from the terminal devices registered using the same SIP account and password to ensure the accuracy of SIP communication.

In this embodiment, the first terminal device is a terminal device corresponding to the SIP account and the password, and in the communication process based on the SIP, only the incoming call information for the SIP account is sent to the first terminal device, or the outgoing call information for the SIP account is sent out from the first device terminal, the accuracy of the communication process based on the SIP can be ensured.

In this embodiment, the fixed telephone number information corresponds to the terminal devices one to one, and in the SIP-based communication service, all the fixed telephone number information is stored in one location server, which is one of the SIP servers, and the location server is actually a database server, and the location server also stores the terminal devices associated with each piece of fixed telephone number information. Thus, in this step, the location server may be requested to retrieve the first terminal device associated with the fixed telephone number information. Illustratively, a device identification of the first terminal device associated with the fixed telephone number information may be acquired.

Step S200: and determining the IP address allocated to the first terminal equipment by the SIP server based on the registration of the first terminal equipment in the SIP server in advance.

The IP Address (Internet Protocol Address) refers to an Internet Protocol Address and is translated into an Internet Protocol Address. The IP address is a uniform address format provided by the IP protocol, and it allocates a logical address to each network and each host on the internet, so as to mask the difference of physical addresses.

In this embodiment, the first terminal device registers in the SIP server in advance by using the fixed telephone number information associated with the first terminal device, the SIP server authenticates the first terminal device in response to the registration request sent by the first terminal device, and if the authentication is passed, the SIP server allocates an IP address to the first terminal device, and then performs the fixed telephone service according to the IP address.

The SIP server allocates an IP address for each terminal device which is successfully registered by using the same fixed telephone number information, and stores the corresponding relation between the terminal device and the IP address. Based on the above principle, the present inventors thought of performing communication related to fixed telephone number information by using the IP address assigned to the first terminal device by the SIP server to ensure the accuracy of fixed telephone communication based on the SIP protocol.

Step S300: and carrying out communication related to the fixed telephone number information according to the IP address.

In the present embodiment, the communication related to the fixed telephone number information is a communication procedure for an incoming or outgoing call of the fixed telephone number information.

In the embodiment, a first terminal device associated with fixed telephone number information is acquired in advance, and then an IP address allocated to the first terminal device by an SIP server is determined; and then the communication process related to the fixed telephone number information is associated with the first terminal device, so that the communication fault possibly caused by the fact that the SIP server cannot distinguish the IP address distributed by the SIP server for the first terminal device from a plurality of legal IP addresses is avoided, and the scheme of the embodiment can improve the communication accuracy.

Referring to fig. 2, fig. 2 is a flowchart of step S200 in the embodiment shown in fig. 1, and as shown in fig. 2, step S200 includes steps S210-S230, which are described in detail as follows:

step S210: the inquiry uses the fixed telephone number information to register a successful IP address in the SIP server.

Although the SIP server allocates an IP address to each terminal device that has successfully registered with the same fixed telephone number information, the source of the terminal device is not authenticated and stored, and SIP communication is performed through the allocated IP address in subsequent SIP communication services for the fixed telephone number. Illustratively, the present embodiment may query the IP address of the terminal device successfully registered in the SIP server using the fixed telephone number information by polling the SIP server. When the fixed telephone number information is not stolen so that other terminal devices except the first terminal device include the fixed telephone number information, only one query result in the step is obtained, namely the IP address allocated to the first terminal device by the SIP server. Otherwise, the query result includes at least two IP addresses.

Step S220: and carrying out IP tracing on the successfully registered IP address to obtain the identifier of the second terminal equipment corresponding to the IP address.

IP tracing refers to a technique for determining the identity or location of a perpetrator and an intermediate medium in a crime process through a network and reducing a crime progress path. In this embodiment, a plurality of IP tracing manners may be used to perform IP tracing, for example, manual tracing, route tracing, characteristic value tracing, patrol tracing, and the like, which is not limited herein.

In this embodiment, the communication service based on the SIP protocol is based on a networking structure that includes a core layer device, a convergence layer device, an access layer device, and a terminal device, which are connected in sequence. In the prior art, a part of the network directly facing a user to connect or access the network is called an access stratum device. The access layer device provides the ability for users to access the application system in the local network segment, mainly solves the mutual access requirement between adjacent users, and provides enough bandwidth for the access. In a large and medium network, the access layer device should also be properly responsible for some user management functions, such as address authentication, user authentication, billing management, etc., and user information collection tasks, such as user IP address, MAC address, access log, etc. Because the primary purpose of access layer devices is to allow end users to connect to the network, access layer switches tend to have low cost and high port density characteristics, often suggesting the use of more expensive devices. The convergence layer device is connected with the core layer device and the access layer device and is positioned in the middle position, the uplink of the convergence layer device is the core switch, and the downlink of the convergence layer device is the access layer switch. The convergence layer device has multiple functions of implementing policy, security, workgroup access, routing between Virtual Local Area Networks (VLANs), source address or destination address filtering, etc., and is where the policy is implemented. Because a convergence layer switch is a convergence point for multiple access layer switches, it must be able to handle all traffic from the access layer devices and provide an uplink to the core layer devices, and therefore, a higher performance and switching speed and fewer interfaces are required for a convergence layer switch as compared to an access layer switch. The convergence layer equipment can be omitted under the conditions that the transmission distance is short and the core layer has enough accesses to be directly connected with the access layer, so that the method is common, the overall cost can be saved, the maintenance burden can be reduced, and the network condition is easier to monitor. The core layer device is a network backbone part and is a guarantee for the performance of the whole network, and the devices comprise routers, firewalls, core layer switches and the like, which are equivalent to the management high layer in the company architecture. The main purpose of the core layer switch is to provide a fast and reliable backbone transmission structure through high-speed forwarding communication, so the core layer switch should have the following characteristics: reliability, efficiency, redundancy, fault tolerance, manageability, adaptability, low latency, etc. Because the core layer is the hub center of the network and is of great importance, the core layer switch should employ giga or even more than ten million manageable switches with higher bandwidth, higher reliability, higher performance and throughput.

Exemplarily, referring to fig. 3, fig. 3 is a flowchart of step S220 in the embodiment shown in fig. 2 in an exemplary embodiment, and as shown in fig. 3, step S220 includes step S221 to step S223, which may perform IP tracing on an IP address in the following manner.

Step S221: and acquiring the MAC address of the convergence layer equipment on the core layer equipment according to the IP address.

The MAC Address (Media Access Control Address), also called a local area network Address, an Ethernet Address or a Physical Address, is an Address for confirming the location of the network device. In this step, obtaining the MAC address of the convergence layer device is to determine the convergence layer device connected to the core layer device, where the convergence layer device is configured to deploy the IP address.

Step S222: and acquiring interface information of the access layer equipment on the convergence layer equipment according to the MAC address of the convergence layer equipment.

In this embodiment, the access layer device is the access layer device connected to the convergence layer device obtained in step S211, and the interface information of the access layer device is the interface information for acquiring the access layer device to deploy the IP address.

Step S223: and acquiring the identifier of the second terminal equipment corresponding to the IP address according to the interface information of the access layer equipment.

By the method, the IP tracing can be carried out on the successfully registered IP addresses, so that all the identifiers of the second terminal equipment corresponding to the IP addresses are obtained, and a foundation is laid for the subsequent processing steps.

After obtaining the identifier of the second terminal device corresponding to the IP address, the obtained result is fed back and displayed on the client, for example, the client is the first terminal device, so that the first terminal device can check whether there is a communication failure by displaying the result. For example, if the client displays that more than one identifier of the second terminal device corresponding to the IP address is acquired, it may be determined that another terminal device also includes the SIP account and the password of the user, and the SIP account and the password are successfully registered in the SIP server, and then the fixed telephone service corresponding to the SIP account may be subsequently involved, otherwise, if the display result indicates that only one identifier of the second terminal device corresponding to the IP address is acquired, it may be determined that the fixed telephone service fault does not occur at present.

Step S230: and if the identifier of the second terminal equipment is the same as the identifier of the first terminal equipment, taking the IP address of the target second terminal equipment as the IP address distributed by the SIP server for the first terminal equipment, wherein the target second terminal equipment is the second terminal equipment with the same identifier as the first terminal equipment.

In this embodiment, step S220 obtains whether there are multiple identifiers or one identifier of the second terminal device corresponding to the IP address, and the obtained identifier of the second terminal device corresponding to the IP address includes an identifier that is the same as the identifier of the first terminal device, so that if there are multiple identifiers of the second terminal device corresponding to the IP address, the identifier that is the same as the identifier of the first terminal device is screened from the multiple identifiers, the second terminal device corresponding to the identifier is used as the target second terminal device, and the IP address corresponding to the target second terminal device is used as the IP address allocated by the SIP server for the first terminal device.

For example, since the SIP server may assign different IP addresses to the first terminal device each time the first terminal device is online and registers based on the fixed telephone number information, in this embodiment, after the first terminal device successfully registers on the SIP server each time, steps S210-230 are repeated to repeatedly determine the IP address assigned by the SIP server to the first terminal device, thereby improving the accuracy of the fixed telephone communication service.

Exemplarily, referring to fig. 4, fig. 4 is a flowchart of step S200 in the embodiment shown in fig. 1 in an exemplary embodiment, and as shown in fig. 4, step S200 includes step S210, step S220 and step S240, which are described in detail as follows:

step S210: the inquiry uses the fixed telephone number information to register a successful IP address in the SIP server. For a detailed description of this step, please refer to a portion of step S210 in the embodiment described in fig. 2, which is not described herein in detail.

Step S220: and carrying out IP tracing on the successfully registered IP address to obtain the identifier of the second terminal equipment corresponding to the IP address. For a detailed description of this step, please refer to the portion of step S220 in the embodiment described in fig. 2, which is not described herein in detail.

Step S240: and if the identifier of the second terminal equipment is different from the identifier of the first terminal equipment, removing the fixed telephone number information stored in the second terminal equipment with the identifier different from the identifier of the first terminal equipment.

In this embodiment, the inventor of the present application considers that, if the identifier of the second terminal device corresponding to the IP address obtained in step S220 includes not only the identifier identical to the identifier of the first terminal device, but also at least one other identifier, and the second terminal device corresponding to the other identifier is obviously fixed phone number information obtained through an illegal channel, in this embodiment, the fixed phone number information in the second terminal device having the identifier different from the identifier of the first terminal device is deleted, so as to ensure that the second terminal devices cannot register on the SIP server by using the fixed phone number information again, thereby eliminating a possible call fault. Note that, in this step, the fixed telephone number information associated with the first terminal device in the eligible second terminal device is deleted instead of the fixed telephone number information associated with the second terminal device.

Exemplarily, referring to fig. 5, fig. 5 is a flowchart of step S200 in the embodiment shown in fig. 1 in an exemplary embodiment, and as shown in fig. 5, step S200 includes step S210, step S220, and step S250, which are described in detail as follows:

Step S250: and if the identifier of the second terminal equipment is different from the identifier of the first terminal equipment, removing the fixed telephone number information stored in the gateway equipment connected with the second terminal equipment with the identifier different from the first terminal equipment.

Gateway devices are also known as internetwork connectors, protocol converters. The gateway realizes network interconnection above a network layer, is a complex network interconnection device and is only used for interconnection of two networks with different high-level protocols. The gateway can be used for interconnection of both wide area networks and local area networks. A gateway is a computer system or device that acts as a switch-operative. The gateway is a translator used between two systems that differ in communication protocol, data format or language, or even in an entirely different architecture. Instead of the bridge simply communicating the information, the gateway repackages the received information to accommodate the needs of the destination system. Same layer-application layer. In the SIP communication service, one end of the gateway device is connected to the SIP server, and the other end is connected to the SIP terminal device, and is used for transmitting communication information between the SIP server and the SIP terminal device.

Since the terminal device needs to register on the SIP server through the gateway device connected thereto, if the terminal device including the fixed telephone number information has performed a registration process through the gateway device connected thereto, the same fixed telephone number information is also stored in the gateway device.

In a specific application scenario, the gateway device does not need to acquire the fixed telephone number information associated with other terminal devices by connecting the gateway device with the terminal device, and in this case, the terminal device may drive the gateway device to register on the SIP server, that is, the second terminal device having the identifier different from that of the first terminal device may not include the fixed telephone number information, but the gateway device connected to the second terminal device having the identifier different from that of the first terminal device necessarily includes the fixed telephone number information. For example, a user a corresponding to a terminal device changes a new gateway device, and hands over an old gateway device to a user B corresponding to another terminal device, the user B connects the old gateway device to the terminal device of the user B, because the fixed telephone number information of the terminal device corresponding to the user a is stored in the old gateway device, the user B can successfully register on the SIP server by using the fixed telephone number information through the old gateway device, and after the old gateway device accesses the SIP server, the SIP server allocates an IP address to the old gateway device, so that the old gateway device can participate in the fixed telephone service related to the fixed telephone number information, and communication disorder is caused. In the prior art, the SIP server selects the IP address of the gateway device successfully registered for the fixed telephone service, but the terminal device connected to the gateway device successfully registered for the latest is not necessarily the terminal device corresponding to the fixed telephone number, so that communication failure is easily caused.

The above application scenario may also be processed by using the communication method of the fixed-line telephone provided in the present application, specifically, it is first determined whether a second terminal device having an identifier different from that of the first terminal device includes fixed-line telephone number information, and if so, step S240 is executed, and a gateway device connected to the second terminal device is determined, and the fixed-line telephone number information of the gateway device connected to the second terminal device is deleted.

By the above manner, the second terminal device with the identifier different from the identifier of the first terminal device can be ensured not to register on the SIP server by using the fixed telephone number information again to disturb the call order, and the accuracy of the SIP call service is further improved.

Exemplarily, referring to fig. 6, fig. 6 is a flowchart of step S200 in the embodiment shown in fig. 1 in an exemplary embodiment, and as shown in fig. 6, step S200 includes step S210, step S220, and step S260, which are described in detail as follows:

Step S260: and if the identifier of the second terminal equipment is different from the identifier of the first terminal equipment, deleting target registration information of the second terminal equipment with the identifier different from the first terminal equipment, which is stored in the SIP server, wherein the target registration information is registration information registered by the second terminal equipment with the identifier different from the first terminal equipment by using the fixed telephone number information.

In this embodiment, since the second terminal device having the identifier different from that of the first terminal device has been successfully registered in the SIP server, the second terminal device having the identifier different from that of the first terminal device is actually authorized to participate in the SIP communication service for the fixed telephone number information associated with the first terminal device, and therefore, in order to completely prevent the second terminal device having the identifier different from that of the first terminal device from disturbing the communication order, the registration information of the second terminal device having the identifier different from that of the first terminal device on the SIP server is deleted.

In this embodiment, the target registration information includes an IP address assigned by the SIP server for identifying a second terminal device different from the first terminal device. Specifically, since the identifier of the second terminal device corresponding to the IP address successfully registered with the fixed telephone number information in the SIP server has been acquired in step S220, it is sufficient to directly screen and delete the IP address corresponding to the identifier of the second terminal device different from the first terminal device from the SIP server.

In this embodiment, by deleting the IP address corresponding to the identifier in the SIP server and the identifier of the second terminal device different from the first terminal device, the accuracy of the SIP communication service can be improved from the source.

Referring to fig. 7, fig. 7 is a flowchart of step S300 in the embodiment shown in fig. 1, and as shown in fig. 7, step S300 includes steps S310 to S330, which are described in detail as follows:

step S310: an outgoing call request associated with the fixed telephone number information is acquired.

In the present embodiment, the outgoing call request related to the fixed telephone number information is a call request issued by the first terminal device related to the fixed telephone number information. The call request includes fixed telephone number information associated with the other terminal device.

Step S320: and judging whether the IP address sending the calling request is the IP address allocated to the first terminal equipment by the SIP server.

In step S200, when the IP address allocated by the SIP server to the first terminal device is determined, the step compares the IP address of the outgoing call request with the IP address allocated by the SIP server to the first terminal device, and if the comparison is successful, determines that the IP address of the outgoing call request is the IP address allocated by the SIP server to the first terminal device.

Step S330: if yes, the outgoing call is allowed.

If the IP address for sending the calling request is determined to be the IP address distributed by the SIP server for the first terminal equipment, the terminal equipment for sending the calling request is indicated to be the first terminal equipment, and therefore the accuracy of the SIP communication service aiming at the fixed telephone number information associated with the first terminal equipment is guaranteed.

Exemplarily, if the IP address sending the outgoing call request is judged not to be the IP address allocated by the SIP server for the first terminal device, an abnormal signal is generated and sent to the background, so that the background stores the IP address sending the call request, and further performs IP tracing on the IP address to obtain an identifier of the second terminal device corresponding to the IP address; and deleting the fixed telephone number information associated with the first terminal equipment in the identifier of the second terminal equipment corresponding to the IP address, deleting the fixed telephone number information associated with the first terminal equipment in the gateway equipment connected with the second terminal equipment, and deleting the registration information registered by the second terminal equipment in the SIP server by using the fixed telephone number information associated with the first terminal equipment.

The method can judge whether the IP address sending the calling request is the IP address allocated by the SIP server for the terminal equipment associated with the corresponding fixed telephone number information, if so, the calling is allowed, and if not, the calling request is intercepted.

Referring to fig. 8, fig. 8 is a flowchart of step S300 in the embodiment shown in fig. 1, and as shown in fig. 8, step S300 includes steps S340-S350, which are described in detail as follows:

step S340: an incoming call request associated with fixed telephone number information is obtained.

In this embodiment, the incoming call request related to the fixed telephone number information is an incoming call request sent by a terminal device other than the first terminal device, and the incoming call request includes the fixed telephone number information associated with the first terminal device. In this embodiment, the other terminal device must be a terminal device that has successfully registered with the SIP server.

Step S350: and sending the incoming call request to the first terminal equipment through the IP address.

In step S100, the first terminal device associated with the fixed telephone number information is obtained, and in step S200, when the IP address allocated to the first terminal device by the SIP server has been determined, the step directly sends the incoming call request to the first terminal device through the IP address allocated to the first terminal device by the SIP server, which can ensure that the SIP communication incoming call service for each fixed telephone number information is participated in by the terminal device corresponding to the corresponding fixed telephone number information, thereby ensuring the accuracy of SIP communication.
