It should be noted that, after the mobile terminal is powered on or restarted, the SIM card sends an STK active command "OPEN CHANNEL" to the mobile terminal.
Step S102: and after receiving the active request command, the mobile terminal sends a request for establishing SOCKET connection to the application server.
Step S103: and after receiving the request for establishing the SOCKET connection, the application server establishes the SOCKET connection with the mobile terminal.
Step S104: after the SOCKET connection is established, the SIM card sends registration information to the application server through the SOCKET connection.
The registration information includes IMSI (international mobile subscriber identity) and ICCID (SIM card number)
Step S105: the application server binds the SOCKET connection to the exclusive connection of the SIM card according to the registration information, and returns response information of successful registration to the SIM card through the SOCKET connection.
It should be noted that, the mobile terminal serving as the middleware forwards the received registration information to the application server, and forwards the received response information of successful registration to the SIM card, where the detailed process of forwarding the response information of successful registration to the SIM card is as follows: the mobile terminal sends event download (effective data) of an ENVELOPE command to the SIM card, informs the SIM card of receiving response information of successful registration from the application server, sends an STK active command 'RECEIVEDATA' to the mobile terminal, and returns response information of successful registration to the SIM card through a terminal response command after the mobile terminal receives the STK active command 'RECEIVE DATA'.
Step S106: the SIM card and the application server are connected through SOCKET to mutually send service messages.
It should be noted that, after completing establishing the SOCKET connection, the application server may actively issue a service message to the SIM card user, and the detailed process is as follows: the mobile terminal sends event download (effective data) of an ENVELOPE command to the SIM card, informs the SIM card to receive service information actively issued by an application server, sends an STK active command 'RECEIVE DATA' to the mobile terminal, and sends the service information to the SIM card through a terminal response command after receiving the STK active command 'RECEIVE DATA'.

It should be noted that the SIM card sends an STK proactive command "TIMER MANAGEMENT" (timer management) to the mobile terminal.
Step S202: and the mobile terminal detects the current SOCKET connection state after a preset time period from the moment of receiving the active timing command.
It should be noted that, the mobile terminal starts a TIMER to start timing after receiving the active timing command, and returns a terminal response result that the TIMER is started successfully to the SIM card, the mobile terminal sends a TIMER EXPIPATION (TIMER expires) of an ENVELOPE command to the SIM card after the time accumulated by the TIMER reaches a preset time period, notifies the SIM card that the timing of the TIMER expires and detects the current state of SOCKET connection, and the SIM card immediately sends an STK active command "GET CHANNEL STATUS" (channel connection state is acquired) to the mobile terminal after receiving the TIMER EXPIPATION (TIMER expires) of the ENVELOPE command.
Step S203: and the mobile terminal sends a terminal response of the current SOCKET connection state to the SIM card.
Step S204: judging the current SOCKET connection state, and if the current SOCKET connection state is a normal connection state, returning to the step S201; if the current SOCKET connection state is the abnormal disconnection state, step S205 is executed.
S205: the SIM card sends an active request command to the mobile terminal and starts to reestablish the SOCKET connection.
Preferably, the method further includes a method for passively recovering SOCKET connection, as shown in fig. 3, where fig. 3 is a method for passively recovering SOCKET connection provided by the present invention, and the specific process is as follows:
step S301: and the mobile terminal detects the SOCKET connection state in real time.
Step S302: and when the SOCKET connection state is an abnormal disconnection state, the mobile terminal sends a disconnection message to the SIM card.
When the mobile terminal detects that the SOCKET connection state is an abnormal disconnection state, the mobile terminal sends an event download (channel connection state) of an ENVELOPE command to the SIM card to notify the SIM card that the SOCKET connection is disconnected.
Step S303: after the SIM card receives the disconnection message, the SIM card sends an active request command to the mobile terminal and starts to reestablish SOCKET connection.
Preferably, the method further comprises:
if the SIM card fails to send the active request command to the mobile terminal and start reestablishing the SOCKET connection, after a preset time threshold value, the SIM card sends the active request command to the mobile terminal again and starts reestablishing the SOCKET connection.
