How to Attempt to Access Short Message in CDMA System

摘要

The present invention relates to a method of accessing a short message in a CDMA system and conventionally, prioritization of a short message is not considered when an attempt is made to access a short message. In the present invention, the mobile station has a setting means capable of assigning a priority, and the mobile station judges whether it is an emergency short message given priority in the persistence test process for an access attempt, and generates a random number RP according to the emergency short message And compares the RP value and the P value calculated by the variable transmitted from the base station with a priority level and compares the value with the RP value and performs the next process of occupying the access channel only when the RP value is small By performing the emergency short message test step, it becomes easy to occupy the access channel in the case of the emergency short message.
