A terminal device and access method

The present invention discloses a method and apparatus for an access terminal, comprising the EAB system configuration parameters corresponding to the bit value of the AC, the AC determines whether to allow access of a terminal, if the EAB parameter values ​​corresponding to the bit AC barred according to prohibit, prohibition time is calculated according to the conventional parameters in the ACB system access barring time again, the process ends; if EAB parameter corresponding to a bit value of AC allow not barred, then the broadcasting system according to the prior Common parameters of the ACB access permission judgment. The method of the present invention will be combined with existing ACB EAB processing mechanisms solve a lot of problems to the system impact of the delay-insensitive or low-priority traffic or a terminal may also bring the access network; moreover, in when an emergency occurs, the applicable terminal of the EAB With proper control, to avoid such direct access to the system terminal with impunity, the process delay is shortened when the emergency system congestion.
