Example 1
Referring to fig. 1, a flowchart of a call method provided in an embodiment of the present application is shown in fig. 1, where the method is applied to a calling device, and includes the following steps:
Specifically, the calling device usually sends invite signaling to the called device, and then establishes a call between the calling device and the called device after the called device responds to the status code, such as 180 or 200 OK. Wherein, the status code 180 represents ringing, and the status code 200OK represents that the called party has answered. The invite signaling usually includes the session type and some parameters necessary for establishing a call. The session type may include voice, multimedia video used for web conferencing, and game sessions.
The process of receiving the call request initiating instruction by the calling device may include: when a user needs to call, the user inputs a number to be called by clicking a numeric key, then clicks a dial key, generates a call initiation request instruction based on the clicking operation of the user, and further triggers the calling of the number. It is to be understood that the above-described processes are exemplary only, and that no limitation to specific processes is intended.
In the embodiment of the present application, the specific location of the address header field is not limited, and the front and back of the location of the header field do not affect the call, so long as the address header field is added to the invite signaling.
And step 120, sending the invite signaling to an SIP server, so that the SIP server adds preset location information to the invite signaling based on a mapping relationship between a pre-stored unique identifier and preset location information of a calling device according to the address header field, and sends the invite signaling to a called device.
Specifically, the invite signaling includes an address header field, so that the SIP server receiving the invite signaling can obtain the preset location information corresponding to the address header field according to the address header field based on the mapping relationship between the pre-stored unique identifier and the preset location information of the calling device, further add the preset location information to the invite signaling, and send the invite signaling including the preset location information to the called device, thereby achieving the purpose that the called device acquires the location information of the calling device. It should be noted here that the unique identifier includes, but is not limited to, a mac address of the phone, the type of the unique identifier does not limit the protection scope of the present invention, and in addition, the mapping relationship of the preset location information of the calling device adopts a location information mapping table in the preferred embodiment, the location information mapping table is a data mapping table identifying phone location information and an IP address of the phone, and the location information mapping table supports later-stage operational functions such as query, uninstallation, and modification.
The mac address is also called a physical address and a hardware address, and is directly burned on the device by a device manufacturer, and is usually represented as 12 16-system numbers, for example: 00-16-EA-AE-3C-40 is a mac address, where the first 3 bytes, the 16-ary number 00-16-EA represents the network hardware manufacturer's number assigned by IEEE (Institute of Electrical and Electronics Engineers), and the second 3 bytes, the 16-ary number AE-3C-40 represents the serial number of a product (e.g., a network card) manufactured by the equipment manufacturer. Because the mac address has uniqueness just like the identity card number, in the embodiment of the application, the mac address is used as the unique identifier to represent the calling device, so that the acquired preset position information also has uniqueness.
In an optional embodiment, the method further comprises:
step 130, obtaining the current position information of the calling equipment;
step 140, adding the current location information in the invite signaling, and adding an indication header field in the invite signaling, wherein the indication header field is used for indicating whether to allow the SIP server to modify the current location information.
Specifically, when receiving the request, the calling device may also actively acquire current location information of itself, and add the current location information to the invite signaling. And then the SIP server can directly acquire the current position information of the calling equipment.
In addition, an indication header field is also added in the invite signaling, and the indication header field is used for indicating whether the SIP server is allowed to modify the current position information.
In an alternative embodiment, the step 120 includes:
adding the current location information in the SDP body of the invite signaling, or
Adding a location header field in the invite signaling, wherein the location header field comprises the current location information.
Specifically, the two ways of adding the current location information in the invite signaling are provided in the embodiments of the present application. The invite signaling includes the SDP body, so the current location information may be added in the SDP body; or adding a location header field in the invite signaling, wherein the location header field comprises the current location information.
It can be understood that the advantage of adding the current location information by adding the additional header field is that SDP (Session Description Protocol) interaction that can ensure a phone terminal call can keep the original Session logic unchanged; the SDP body is used for carrying the position information, and the method has the advantages that the signaling penetration problem does not exist at the server side, the server does not need to be developed in a matching way, and the compatibility is relatively strong.
Two ways of obtaining the current location information of the calling device according to different types of the calling device provided in the embodiment of the present application will be specifically described below.
In an alternative embodiment, the calling device includes a volte phone, and step 110 includes:
and acquiring the current position information of the calling equipment through a satellite positioning module.
Specifically, a Voice over Long-Term Evolution (lte) phone is generally a mobile terminal and includes a satellite positioning module, so that current location information of a calling device can be obtained through the satellite positioning module, and accuracy of the current location information is ensured.
The satellite Positioning module includes at least one of a Global Positioning System (GPS), GLONASS (GLONASS), beidou, and Galileo (Galileo). The current position information of the calling equipment can be determined by a plurality of satellite positioning modules together, so that the accuracy of the current position information of the calling equipment is improved. When the current position information of the calling device is determined by the plurality of satellite positioning modules together, the average value of all the current position information can be directly obtained, and different weights can be distributed to the current position information obtained by each different satellite positioning module.
In another optional embodiment, the calling device includes a SIP phone, and the step 110 includes:
and acquiring the position information prestored in the calling equipment as the current position information of the calling equipment.
Specifically, an SIP (Session initiation Protocol) phone is a phone supporting an SIP Protocol, and access is performed by using a network cable or a WIFI (Wireless Fidelity) signal, that is, a network can be used, and a 4G (the 4th generation mobile communication technology) signal of a mobile phone can be used to access the SIP. The SIP phone can also integrate a video function, and if supported by an operator, two SIP phones with the video function can carry out video call or video between a video access control and the SIP phone. The SIP phone usually pre-stores the position information of the SIP phone, so that the position information can be directly used as the current position information of the SIP phone, the reacquisition is avoided, and the processing efficiency is improved.
According to the communication method provided by the embodiment of the application, the address header field is added in the invite signaling sent to the SIP server by the calling device, and the address header field comprises the unique identifier of the calling device, so that the SIP server can add the preset position information corresponding to the address header field to the invite signaling based on the mapping relation between the pre-stored unique identifier and the preset position information of the calling device, and then send the preset position information to the called device, and therefore the called device can obtain the position information of the calling device.

Specifically, the SIP server receives invite signaling including an address header field sent by the calling device. Since the address header field comprises the unique identification of the calling device, it can then be used in subsequent steps.
Specifically, the unique identifier has uniqueness, so that the preset position information obtained based on the mapping relationship also has uniqueness.
Specifically, the preset location information is added to the invite signaling and then sent to the called device, so that the called device obtains the location information of the calling device.
In an optional embodiment, the invite signaling further includes current location information of the calling device and an indication header field, where the indication header field is used to indicate whether the SIP server is allowed to modify the current location information;
the method further comprises the following steps:
analyzing the invite signaling to obtain the indication header field;
if the indication header field indicates that the SIP server is allowed to modify the current position information, comparing the preset position information with the current position information;
and if the preset position information is inconsistent with the current position information, packaging the preset position information and the unique identifier, adding the packaged preset position information and the unique identifier to the invite signaling, and sending the invite signaling to the called equipment.
Specifically, under the condition that the invite signaling further includes an indication header field and the current location information of the calling device, the invite signaling is analyzed to obtain the indication header field.
If the indication header field indicates that the SIP server is allowed to modify the current position information, comparing the preset position information with the current position information, and if the preset position information is inconsistent with the current position information, packaging the preset position information and the unique identifier and adding the packaged preset position information and the unique identifier to the invite signaling, and then sending the invite signaling to the called equipment. It can be understood that if the preset position information is not consistent with the current position information, no processing is required.
It should be noted that, if the indication header field does not allow the SIP server to modify the current location information, the SIP server directly sends an invite signaling including the current location information to the called device.
According to the communication method provided by the embodiment of the application, the SIP server can add the preset position information corresponding to the address header field to the invite signaling and then send the invite signaling to the called device based on the mapping relation between the pre-stored unique identifier and the preset position information of the calling device, so that the called device can acquire the position information of the calling device.
