Method for Processing Abnormal Core Network Disconnection and Terminal

A method, comprising:

• attempting, by a first terminal, to connect to a second terminal;
• when a notification message indicating an abnormal core network disconnection is received, obtaining, by the first terminal, a cause value of the abnormal core network disconnection from the notification message;
• determining, by the first terminal, whether the cause value exists in a preconfigured first cause value list;
• and
• when it is determined that the cause value exists in the preconfigured first cause value list, reattempting by the first terminal, to connect to the second terminal.

A first terminal, comprising:

• a radio frequency circuit;
• and
• a processor;
• wherein the processor is configured to:
• attempt to connect to a second terminal;
• when receiving, using the radio frequency circuit, a notification message indicating an abnormal core network disconnection, obtain a cause value of the abnormal core network disconnection from the notification message;
• and
• when it is determined that the cause value exists in a preconfigured first cause value list, reattempt to connect to the second terminal.

A non-transitory computer-readable media storing computer instructions that, when executed by one or more processors, cause the one or more processors to:

• attempt to connect to a terminal;
• when receiving a notification message indicating an abnormal core network disconnection, obtain a cause value of the abnormal core network disconnection from the notification message;
• and
• when it is determined that the cause value exists in a preconfigured first cause value list, reattempt to connect to the terminal.
