Description

A SIM card connection control method and device

technical field

The invention relates to the technical field of communication, in particular to a connection control method and device for a SIM (Subscriber Identity Module, customer identification module) card.

Background technique

With the rapid development of communication technology, the application requirements of user terminals such as mobile phones and handheld computers are increasingly strong. Most user terminals need SIM cards for normal communication. The SIM cards configured in user terminals have the ability to store user data and identify user Functions such as authentication, user PIN operation, and user terminal information management. After the user terminal is turned on, it needs to exchange data with the SIM card. When receiving the signal response from the SIM, the user terminal scans the network signal of the SIM card through the radio frequency module, and tries to connect the SIM card to the communication network. After the communication network authentication is passed, the user terminal The terminal can make normal online calls.

At present, the user terminal is connected to the network through the SIM card. When the SIM card is in arrears or canceled, it will enter the account cancellation procedure. At this time, the network service provider will delete the user data belonging to the SIM card from the network side, and the user can no longer use the SIM card. This process is called canceling the account of the SIM card. Generally, the SIM card after canceling the account will be taken out or discarded by the user, so that the user terminal cannot detect the SIM card after starting up, and then stops scanning the network signal of the SIM card, completely disconnecting the network access of the canceled SIM card.

However, in some user terminals, the SIM is difficult to be removed or discarded. For example, with the popularity of the Internet of Things, after the SIM card used on the Internet of Things is canceled, it is inconvenient for the user to remove the SIM card of the user terminal. After the SIM card is canceled, the user terminal can still receive the signal response of the SIM card after it is turned on. At this time, the user terminal will also scan the network signal of the canceled SIM card, and try to access the canceled SIM card. Network, because the network service provider has deleted the user data of the SIM card, making the SIM card unable to access the communication network, so the user terminal will continue to scan the network signal of the SIM card, which greatly occupies network resources.

To sum up, in the current IoT user terminal application, after canceling the SIM card of the user terminal, the SIM card after canceling the account cannot be completely disconnected from the communication network, resulting in a waste of network resources and affecting network indicators. .

The method according to claim 5, wherein the control information includes an IMSI number and a PIN code of the SIM card. 8. A connection control device for a SIM card, characterized in that it comprises: The connection unit is configured to scan the network signal for the SIM card after the user terminal detects the SIM card, and send a network access request for connecting the SIM card to the network to the network side; The processing unit is configured to, after the user terminal receives the control information sent by the network side, close the radio frequency signal transmission function of the user terminal according to the control information; or lock the SIM card according to the control information, and Disconnecting the user terminal from the network side, so that after the user terminal detects the SIM card, it stops scanning network signals for the SIM card; Wherein, the control information is sent by the network side after determining that the SIM card has been canceled. 9. The device according to claim 8, wherein the network access request includes the IMSI data of the SIM card; The processing unit disconnecting the connection between the user terminal and the network side includes: Turn off the radio frequency signal transmission function of the user terminal; or Requesting the network side to delete the IMSI data of the SIM card. 10. The device according to claim 8, wherein the control information includes the IMSI number and PIN code of the SIM card; The processing unit locks the SIM card according to the control information, including: The processing unit identifies the SIM card according to the IMSI number; The processing unit locks the SIM card by using the PIN code. 11. A connection control device for a SIM card, characterized in that it comprises: The receiving unit is configured to receive a network access request for connecting the SIM card to the network sent by the user terminal; receive a request for deleting the IMSI data of the SIM card sent by the user terminal; delete the IMSI data of the SIM card , to disconnect the user terminal from the network side; The sending unit is configured to send control information to the user terminal after determining that the SIM card has been canceled, so that the user terminal stops accessing the SIM card to the network. 12. The device according to claim 11, wherein the network access request includes the IMSI data of the SIM card; The sending unit determines that the SIM card has been canceled, including: The sending unit determines that the SIM card fails to access the network; The sending unit extracts the IMSI number of the SIM card from the network connection message; The sending unit inquires whether the user data of the SIM card is normal according to the IMSI number, and if not, considers that the SIM card has been canceled. 13. The device according to claim 12, wherein the sending unit determines that the user terminal fails to connect to the network, comprising: The sending unit judges that the SIM card fails to access the network for at least N consecutive times according to the received network access request, and then determines that the SIM card fails to access the network. 14. The device according to claim 12, wherein the control information comprises an IMSI number and a PIN code of the SIM card.
