Link failure report transmission method and apparatus

An apparatus comprising:

• at least one processor;
• and
• a non-transitory memory coupled to the at least one processor, the memory comprising instructions that, when executed by the at least one processor, cause the apparatus to:
• send a first link failure report to a second radio access network device that is to serve the apparatus, wherein the first link failure report indicates that a link between the apparatus and a first radio access network device fails, and the first radio access network device is a secondary radio access network device of a third radio access network device;
• and
• wherein sending the first link failure report to the second radio access network device that is to serve the apparatus comprises:
• sending the first link failure report to the second radio access network device when the apparatus is successfully handed over from the third radio access network device to a fourth radio access network device and a link between the apparatus and the fourth radio access network device fails within a preset time interval.

An apparatus comprising:

• at least one processor;
• and
• a non-transitory memory coupled to the at least one processor, the memory comprising instructions that, when executed by the at least one processor, cause the apparatus to:
• receive a first link failure report from a terminal to be served by the apparatus, wherein the first link failure report indicates that a link between the terminal and a first radio access network device fails, and the first radio access network device is a secondary access network device of a third radio access network device;
• send the first link failure report to the third radio access network device;
• and
• receive a second link failure report from the terminal, wherein the second link failure report indicates that a link between the terminal and a fourth radio access network device fails.
