<p>An accessing method of Physical Random Access Channel (PRACH) is disclosed by the present invention. A network element of an accessing network sets up PRACH classification information according to terminal characteristic types, and sends the PRACH classification information to a terminal; then according to its terminal characteristic type, the terminal selects a corresponding PRACH from the PRACH classification information so as to initiate a random access. An accessing system of PRACH is also disclosed by the present invention. The technical solution of the present invention enables a terminal to access a PRACH according to its terminal characteristic type, thus avoiding the influence of dense access of Machine to Machine (M2M) terminals to the access of a Human to Human (H2H) terminal, and ensuring the wireless access Quality of Service (QoS) requirement of the H2H terminal.</p> |
