Step S101: The missed call server obtains during the call of the called terminal by the calling terminal through the mobile network. The call message generated by the missed call client of the calling terminal and sent through the IP network is taken.

The call message includes a calling terminal number and a called terminal number.

Before performing the step S101, establishing a socket connection for message delivery between the missed call server and the missed call client of the calling terminal, for the missed call client of the calling terminal A call message including a calling terminal number and a called terminal number is delivered to the missed call server using the socket connection.

Optionally, the socket connection between the missed call server and the missed call client of the calling terminal may be established by the missed call server, or may be established by the missed call client of the calling terminal. . When the missed call server is established, the missed call server needs to obtain the IP address of the missed call client of the calling terminal in advance, so as to establish a socket by using the IP address of the missed call client of the calling terminal. connection.

Step S102: The missed call server queries the current state of the called terminal according to the received call message.

Before the step S102, establishing a socket connection for message delivery between the missed call server and the missed call client of the called terminal, for the called terminal to utilize the socket The connection transmits the current state information of the called terminal to the missed call server.

The missed call server obtains the calling terminal number and the called terminal number by parsing the call message, and uses the obtained called terminal number to query by one of the following two methods: Call the current status of the terminal:

Manner 1: The missed call server queries the missed call client of the called terminal corresponding to the called terminal number through the IP network to query the current state of the called terminal.

Manner 2: The missed call server queries the current state of the called terminal corresponding to the called terminal number through a local real-time updated terminal state database.

Step S103: The missed call server generates a missed call notification message according to the current state of the called terminal, and sends the missed call message to the called terminal of the called terminal through the IP network.

When the current state of the called terminal that is queried by the missed call server is any one of shutdown, unreachable, user busy, and no response, a missed call notification message including the calling terminal number is generated, and the a socket connection between the missed call server and the missed client of the called terminal The missed call notification message is sent to the missed call client of the called terminal.

Optionally, if the short connection mode is established, the missed call server/the missed call client of the calling terminal/the missed call client of the called terminal establishes a corresponding socket connection before sending a message. And disconnect the established socket connection after sending the message.

Optionally, if the long connection mode is established, the missed call client of the calling terminal/the missed call client of the called terminal initiates a timeout to the missed call server after the corresponding socket connection is established. The heartbeat detects the request in order to maintain the established socket connection.

The embodiment of the invention is a missed call reminding application based on the IP network, which provides a new experience for the incoming call reminding user to receive the missed reminder message based on the IP network.

3 is a block diagram of a missed call reminding system according to an embodiment of the present invention. As shown in FIG. 3, when a calling terminal calls a called terminal through a mobile network provided by an operator, the missed call client of the calling terminal goes to the leak through the IP network. The server sends a call message containing the calling terminal number and the called terminal number. The missed server queries the missed call client of the called terminal through the IP network according to the called terminal number to query the current state of the called terminal. When the current state of the called terminal is queried, unreachable, busy, and unanswered, the missed server generates a missed call notification message including the calling terminal number and the calling time, and passes the IP. The network sends the missed call notification message to the missed call client of the called terminal, so that the called user knows the missed situation in time.

It should be noted that the missed call client of the called terminal may be installed on the called terminal as shown in FIG. 3, or may be installed on other IP-based terminal devices such as a tablet computer. For example, if the calling terminal calls the called terminal when the called terminal is powered off, the missed server can send a missed call notification message to the tablet of the missed client that has installed and opened the called terminal through the IP network.

The same user, as long as he has an account, can conveniently receive and upload the IP client software through the loaded IP client software on various terminal devices (such as smart phones, iPads, etc.). Manage missed messages.

As shown in FIG. 4, a socket connection is established between the MC server 1 and the MC client 2, and the MC server 1 and the MC client 2 are connected. Message passing is achieved through the Socket connection.

The MC server 1 on the network side serves the MC client, and the MC system interacts with the MC client through an agreement protocol to complete the notification of the status of the called terminal number and the notification function of the missed call information. Optionally, the MC server end 1 is also responsible for the management of Socket communication on the server side.

The MC client 1 located on the terminal side is software that implements the MC function on the IP-based terminal side. The calling user connects to the MC server through the MC client, and reports the calling and called terminal number information to the MC server through the contract protocol, and other agreed operations; the called user connects to the MC server through the MC client. End, and report the current status of the called user to the MC server through the contract. Optionally, the MC client 2 is also responsible for the application and management of the Socket communication on the client.

End, for example, running the MC client on a tablet and running the MC client on the TV.

The Socket connection is also called a Socket channel, and refers to all Socket data channels and data communication mechanisms.

The Socket connection can be established and maintained between MC server 1 and MC client 2 as follows:

Mode 1: For the long connection mode, the MC client 2 initiates a request to establish a Socket connection with the MC server 1, and the MC client 2 establishes and maintains a Socket connection with the MC server 1 by periodically sending a heartbeat message packet. After the connection is successful, the user is authenticated with the password security authentication. After the authentication succeeds, the MC client periodically initiates heartbeat monitoring to maintain the Socket connection. When the heartbeat monitoring does not receive a response from the MC server, the MC client considers that the Socket connection detection fails, and the MC client re-initiates the request to establish a Socket connection. That is, the Socket connection between the MC server 1 and the MC client 2 can be initiated by the MC client, and after the connection is successful, the MC client 2 periodically initiates a heartbeat message to detect the Socket connection, and detects When the Socket connection fails, the MC client re-initiates the Socket connection.

Mode 2: For the short connection mode, the Socket connection that the MC client 2 sets to deliver a message to the MC server is initiated by the MC client 2, and after the message is delivered, the MC client 2 Disconnecting the Socket; the Socket connection that the MC server 1 is configured to deliver a message to the MC client 2 is initiated by the MC server 1, and after the message is delivered, the MC server 1 is disconnected. Open the Socket connection. It is to be noted that, before the MC server 1 initiates the Socket connection, the MC client 1 initiates a Socket connection to the MC server 1 and after the connection is successful, the MC server 1 records the The IP address of the MC client 2, and then the MC client 2 disconnects the Socket connection, so that the MC server 1 can initiate a Socket connection according to the recorded IP address of the MC client 2.

Optionally, the message delivered by the MC server end 1 and the MC client 2 through the Socket connection may adopt the same message type and content format as the short message service (SMS).

Optionally, the message delivered by the MC server end 1 and the MC client 2 through the Socket connection includes a message for system notification and/or missed call management.

The MC client periodically initiates a heartbeat detection message, and the MC server receives the heartbeat detection message and feeds back the heartbeat detection response message, and the MC client detects and maintains the state of the Socket channel according to the heartbeat detection response message of the MC server. When the heartbeat monitoring is not received by the MC server, the MC client considers that the Socket connection detection fails. At this time, the MC client re-enters the MC server to initiate a request for establishing a Socket connection.

Step 208: The MC client interacts with the MC server through the Socket channel to perform user status query management.

Through the Socket connection channel, the user status query management function implemented by the MC client and the MC server to exchange Socket messages includes: querying the current status of the called user, including but not limited to the user busy, shutdown, unreachable, and no response.

Step 209: After generating the system notification message, the MC server sends the Socket channel to the MC client, and performs user status query management through the Socket channel.

The MC server can send the MC client through the Socket channel when there is a system notification message. The system notification message is a message sent by the system to the MC client, including a missed reminder message and a power-on reminder message.

The case where the MC server sends a system notification message includes but is not limited to the following two types:
