Gateway recovery processing method and device

A device for gateway recovery processing, applied to a first mobility management unit, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor,
• wherein when executing the instructions, the processor is configured to:
• receive Packet Data Network (PDN) connection signaling, and trigger a paging procedure for a terminal;
• in response to determining that the paging procedure fails, set and store flag information, wherein the flag information is used to indicate that the PDN connection signaling is in a suspended state;
• and
• in a case where the terminal moves from the coverage area of the first mobility management unit to a coverage area of a second mobility management unit, send the flag information to the second mobility management unit, wherein the flag information is used for the second mobility management unit to trigger a Serving Gateway (SGW) to send a bearer update request message to a PDN Gateway (PGW).

A non-transitory computer-readable storage medium, having stored thereon instructions which, when executed by a processor, cause the processor to perform a method comprising:

• receiving, by a first mobility management unit, Packet Data Network (PDN) connection signaling, and triggering a paging procedure for a terminal;
• in response to determining that the paging procedure fails, setting and storing, by the first mobility management unit, flag information, wherein the flag information is used to indicate that the PDN connection signaling is in a suspended state;
• and
• in a case where the terminal moves from a coverage area of the first mobility management unit to a coverage area of a second mobility management unit, sending, by the first mobility management unit, the flag information to the second mobility management unit, wherein the flag information is used for the second mobility management unit to trigger a Serving Gateway (SGW) to send a bearer update request message to a PDN Gateway (PGW).
