Abstract
Abstract A method and apparatus for updating transmission power class information of a Mobile Station (MS) in a General Packet Radio Services (GPRS) network. The invention updates transmission power class information of the MS in the GPRS network by initiating a Routing Area Update (RAU) procedure in the MS. The RAU procedure includes sending from the MS to a Serving GPRS Support Node (SGSN) of the GPRS network a RAU request message including a MS Radio Access Capability (RAC) Information Element (IE) which includes an IE indicating a new transmission power class of the MS, accepting in the SGSN the IE indicating a new transmission power class of the MS included in the MS RAC of the RAU request message, and delivering to a Base Station (BSS) the IE indicating a new transmission power class of the MS, thereby updating the transmission power class information of the MS at the BSS.
