METHOD FOR RANDOM ACCESS PROCESS IN MOBILE COMMUNICATION SYSTEM
First Claim
1. A method for a random access process in a mobile communication system, comprising:
- requesting random access to a network;
maintaining a standby state without repeatedly requesting the random access to the network when a mobile terminal receives from the network a queued acknowledge (QACK) for notifying the mobile terminal to be in the standby state; and
releasing the standby state of the mobile terminal and communicating with the network when the mobile terminal receives from the network an acknowledge (ACK) for notifying the mobile terminal to grant the random access.

Abstract
The present invention relates to a method for a random access process in a mobile communication system. According to the exemplary embodiments, in the case where a mobile terminal requests a random access to a network, when the network is not able to promptly allocate a resource for the random access to the mobile terminal due to an insufficient resource, the mobile terminal is maintained in a standby state without repeatedly requesting the random access to the network. Accordingly, it is possible to reduce the uplink signal interference caused by the repeated random access request, reduce the possibility of communication contention between the mobile terminals for the access to the mobile communication system, and reduce the power consumption of the mobile terminal.

6. A method for a random access process in a mobile communication system comprising:
-
receiving a random access request from a mobile terminal by a network; storing the random access request information transmitted from the mobile terminal and transmitting to the mobile terminal a queued acknowledge (QACK) to notify the mobile terminal to be in a standby state when a resource allocation for a random access of the mobile terminal is checked to be impossible, by the network; and transmitting to the mobile terminal requesting the random access an acknowledge (ACK) to notify the mobile terminal to grant the random access on the basis of a stored random access request information when the resource allocation becomes possible, by the network. - View Dependent Claims (7, 8, 9, 10)
