3.4.10 Classmark change procedure

3GPP44.018GSM/EDGE Radio Resource Control (RRC) protocolMobile radio interface Layer 3 specificationRelease 17TS

In dedicated mode or in group transmit mode, this procedure allows the mobile station to indicate to the network a change of characteristics reflected in the classmark (e.g. due to addition of power amplification). Furthermore, a mobile station which implements the "controlled early classmark sending" option may also send a CLASSMARK CHANGE message and/or a UTRAN CLASSMARK CHANGE message and/or a CDMA2000 CLASSMARK CHANGE message and/or a GERAN IU MODE CLASSMARK CHANGE message as described in sub-clause 3.3.1.1.4.1, even if no change of characteristics has occurred.

The mobile station sends a CLASSMARK CHANGE message to the network. This message contains the new mobile station classmark 2 information element. It may also contain a Classmark 3 Information Element. There is no acknowledgement from the network at layer 3.

A UTRAN capable MS, independently of sending a CLASSMARK CHANGE message, sends a UTRAN CLASSMARK CHANGE message to the network. This message contains the INTER RAT HANDOVER INFO defined in 3GPP TS 25.331. There is no acknowledgement from the network at layer 3.

NOTE: For the network, UTRAN predefined configuration status information may be invalid if the PLMN where predefined configurations were read and the PLMN of the connected cell do not use common predefined configurations.

A CDMA2000 capable MS sends a CDMA2000 CLASSMARK CHANGE message to the network.

A GERAN Iu mode capable MS, independently of sending a CLASSMARK CHANGE message, sends a GERAN IU MODE CLASSMARK CHANGE message to the network. This message contains the MS GERAN IU MODE RADIO ACCESS CAPABLITY IE defined in 3GPP TS 44.118. There is no acknowledgement from the network at layer 3.

If the CLASSMARK CHANGE and one or more of these additional messages are to be sent by the MS, the CLASSMARK CHANGE message shall be sent first.
