Claim Text:
1. A method for processing a random access parameter, comprising: receiving, by a network device, capability information that indicates whether one or more user terminals support random access parameter optimization, as reported by the one or more user terminals; detecting, by the network device, according to the capability information, whether the one or more user terminals support the random access parameter optimization; issuing, by the network device based on one of a periodic and an event-triggered mechanism, indication information that instructs the one or more user terminals to record a random access report if the one or more user terminals support the random access parameter optimization; receiving, by the network device, the random access report of a first cell reported by the one or more user terminals, wherein a random access detection item recorded in the random access report comprises at least one of: a number of occurrences of a preamble cycle period in each random access, a reason for preamble transmission failure within each preamble cycle period and a random access delay, wherein when one of a number of occurrences of a random access failure (m) divided by a total number of times of access (n), an average access delay, an average number of times of preamble transmission, and number of times of preamble cycle ramp is greater than or equal to the second preset threshold, the random access report of the first cell received by the network device is spontaneously reported by the user terminal; performing, by the network device, random access detection item statistics according to the random access report and obtaining a statistical value; if the statistical value reaches a preset threshold, adjusting, by the network device, the random access parameter of the first cell; and issuing, by the network device, the adjusted random access parameter to a user terminal belonging to the first cell.
