The PROTOBUF is a serialization framework of Google open source, is similar to XML, json and the like, has the greatest characteristic that communication data are based on binary systems, are much more simplified than communication data in the traditional XML form, and can be used for communication between a server and a client, such as communication between terminal equipment and an OTT platform in the embodiment of the invention.
The multimedia communication Protocol request is constructed based on a multimedia communication Protocol, and the multimedia communication Protocol (Session Initiation Protocol, SIP for short) is a part of an Internet multimedia communication and control Protocol system and is also one of key protocols of a Next Generation Network (NGN), so that the embodiment of the invention converts the first registration request into a request based on the multimedia communication Protocol.
In order to further determine that information interaction can be normally performed between the OTT platform and the terminal device, after the OTT platform obtains a multimedia communication protocol request, an account opening request is sent to the terminal device.
In detail, in S102, when receiving a first registration request of the terminal device, sending an account opening request to the terminal device includes: converting the first registration request into a multimedia communication protocol request by using a signaling gateway in the OTT platform; when the multimedia communication protocol request is successfully converted, initiating a registration request to a registration server of the OTT platform; and when the registration server successfully receives the registration request, sending the account opening request to the terminal equipment.
In a preferred embodiment of the present invention, the main purpose of the account opening request is to enable the terminal device to receive and respond to the account opening information to verify that information interaction can be performed between the OTT platform and the terminal device, thereby ensuring the communication between the terminal device and the communication device.
S103, opening an account for the terminal equipment when receiving a second registration request sent by the terminal equipment and account opening information corresponding to the account opening request.
In detail, in a preferred embodiment of the present invention, when the terminal device receives the account opening request, the account opening request is automatically analyzed, if the OTT platform sends the account opening request that requires the terminal device to return one byte of data, when the terminal device successfully receives the account opening request, a second registration request is sent, the second registration request is also sent in the form of a TCP protocol of a private PROTOBUF, and meanwhile, the terminal device also sends the account opening information of one byte of data, and when the OTT platform successfully receives the second registration request and the account opening information, the account opening information is opened.
In detail, the invoking the registration server to open an account for the terminal device includes: analyzing the second registration request by using the registration server to obtain verification information; judging whether the account opening information is consistent with the verification information or not, and if the account opening information is inconsistent with the verification information, sending an account opening non-passing request to the terminal equipment; and if the account opening information is consistent with the verification information, sending an account opening passing request to the terminal equipment.
For example, if the account opening information sent to the terminal device is to inform the terminal device to send one byte of data account opening information, and the received account opening information is two bytes of data sent by the terminal device, it indicates that the interaction between the OTT platform and the terminal device is unsuccessful, at this time, the interaction can be directly stopped, and a tester waits for device detection, and if the account opening information is consistent with the verification information, an account opening pass request is sent to the terminal device, i.e., a call request sent by the terminal device can be received.
The embodiment of the invention firstly sends a session invitation request to a pre-constructed IP multimedia subsystem according to the call request of the terminal equipment to the user, when the IP multimedia subsystem sends a communication building message, an audio and video communication channel between the terminal equipment and the communication equipment can be built, because the audio and video communication channel is carried based on the communication network, the communication equipment can be directly called by using the terminal equipment, compared with the method that the terminal equipment calls the APP installed in the communication equipment, because the APP is based on the WIFI network or the traffic packet, when the network is disconnected or the APP in the communication equipment is not started, the phenomenon that the terminal equipment cannot contact the mobile phone in time can be caused, therefore, the embodiment of the invention takes the audio and video call channel as the call basis, and solves the problem that the terminal equipment and the communication equipment cannot be connected because the communication equipment is not connected with the network or APP software in the communication equipment is not started.
