Radio Communication Apparatus and Method of Control
First Claim
1. A radio system comprising a radio communication apparatus and a radio station,said radio station including transmitter means for transmitting intermittently an access parameter for use by the radio communication apparatus in transmitting an access message;
- wherein the transmitter means is adapted to transmit a validity indicator;
said radio communication apparatus including receiver means for receiving said access parameter from the radio station;
storage means for storing a value of the latest received access parameter; and
transmitter means for transmitting an access signal;
wherein the receiver means is adapted to receive the validity indicator transmitted by the radio station; and
further comprising control means adapted to employ the stored value of the latest received access parameter for the transmission of the access signal, or wait to receive the next access parameter and employ the value of said next access parameter for the transmission of the access signal, depending on at least a value of said validity indicator.

Abstract
A method of operating a radio communication apparatus (100), comprises receiving an access parameter transmitted intermittently by a radio station (200), storing a value of the latest received access parameter, and transmitting an access signal. It further comprises receiving a validity indicator transmitted by the radio station (200), and if the validity indicator has a first value, employing the stored value of the latest received access parameter to transmit the access signal, and if the validity indicator has a second value, waiting to receive the next random access parameter and employing the value of said next access parameter to transmit the access signal.
