CM3 (classmark 3) information consists of information about the powers of various bands of multi-band MS. In the handover between various bands, the power level must be described correctly. CM3 message must be known when paging is conducted and BA2 table is sent in different bands. ECSC is valid mainly for dual-band MS only. For dual-band MS, when ECSC is not used, MSC will still send the CLASSMARK REQUEST message after MS reports ESTIND. When MS reports the CLASSMARK UPDATE message, other functions will not be affected.
