Data transmission in a TDMA system
First Claim
1. A method of updating transmission power class information of a Mobile Station (MS) in a packet switched network comprising:
- updating transmission power class information of the MS in the network by initiating a Routing Area Update (RAU) procedure in the MS, wherein said RAU procedure comprises;
sending from said MS to a Serving Support Node (SSN) of the network a RAU request message including a MS Radio Access Capability (RAC) Information Element (IE) which includes a field indicating a new transmission power class of the MS, accepting in said SSN said IE indicating a new transmission power class of the MS included in said 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, wherein the delivering to the Base Station (BSS) the IE indicating the new transmission power class of the MS, thereby updating the transmission power class information of the MS at the BSS occurs during a transmission.

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.

19. A Mobile Station for use in a packet switched network having a function of updating transmission power class information, said network includes a Serving Support Node (SSN), and a Base Station (BSS), said MS comprising:
-
a Radio Frequency (RF) unit which transmits and receives wireless signals; and
a control unit which updates transmission power class information of the MS in the GPRS network by initiating a Routing Area Update (RAU) procedure in the MS, wherein said RAU procedure comprises;
sending from said MS to said SSN of the network a RAU request message including a MS Radio Access Capability (RAC) Information Element (IE), which includes a field indicating a new transmission power class of the MS, accepting in said SSN said IE indicating a new transmission power class of the MS included in said MS RAC of the RAU request message, and delivering to said 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, wherein the delivering to the Base Station (BSS) the IE indicating the new transmission power class of the MS, thereby updating the transmission power class information of the MS at the BSS occurs during a transmission. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
