Mobile terminal and access method for enhanced uplink random access channel

摘要

The present invention provides a mobile terminal and an access method for an E-RUCCH. The method comprises: when upload data authorization information has expired and the amount of buffer data in a logical channel of the mobile terminal is zero, starting a timer; judging whether or not the timer is timed out, and if upload data authorization information is received before the timer is timed out, resetting the timer and initiating an E-RUCCH access; if the upload data authorization information is not received before the timer is timed out, resetting the timer when the timer is timed out and judging whether there is any buffer data in the logical channel; and when the amount of the buffer data in the logical channel exceeds a threshold of the buffer data in the logical channel, initiating the E-RUCCH access. Through the above-mentioned method and the mobile terminal, it is able to control the E-RUCCH access time of the mobile terminal and prevent the mobile terminal from initiating unnecessary, frequent access.

1. An access method for E-DCH (Enhanced Dedicated Channel) Random Access Uplink Control Channel (E-RUCCH) of a mobile terminal, comprising:
determining whether upload data authorization information has expired; determining whether an amount of buffer data in a logical channel of the mobile terminal is zero; starting a timer when it is determined that the upload data authorization information has expired and the amount of buffer data in the logical channel of the mobile terminal is zero; determining whether the timer is timed out; determining whether new upload data authorization is received by the mobile terminal; resetting the timer and initiating an E-RUCCH access if it is determined that the new upload data authorization information is received before the timer is timed out; resetting the timer and determining whether there is any buffer data in the logical channel if it is determined that the upload data authorization information is not received before the timer is timed out; and initiating the E-RUCCH access when the amount of the buffer data in the logical channel exceeds a threshold of the buffer data in the logical channel.
