Method for data transmission, method for parameter optimization, apparatus, and device

A method for parameter optimization, comprising:

• receiving, by a first network device, random access failure information or resource request failure information sent by user equipment UE;
• determining, by the first network device, based on the random access failure information or the resource request failure information, whether the first network device is a first network device recorded in the random access failure information or the resource request failure information;
• and
• if the first network device is the first network device recorded in the random access failure information or the resource request failure information, reporting, by the first network device, the received random access failure information or resource request failure information to a network management device, so that the network management device performs optimization processing on random access parameters or cell parameters of the resource request.

A data transmission apparatus, comprising:

• a memory, a processor, and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the computer program to:
• initiate a random access request or a resource request to a network device;
• record random access failure information or resource request failure information;
• detect whether the network device is successfully accessed;
• and
• when it is detected that the apparatus has successfully accessed the network device, send the random access failure information or the resource request failure information to the network device, so that the network device sends the random access failure information or the resource request failure information to a network management device for parameter optimization processing.
