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 (E) 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.

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.

10. A packet switched network having a function of updating transmission power class information, comprising:
-
at least one Mobile Station (MS);
a Serving Support Node (SGSN); and
a Base Station (BSS), wherein transmission power class information of the MS in the GPRS network is updated 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 20, 21, 22, 23, 24, 25, 26, 27)

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.
