在3GPP TS 24.008中談到classmark I 和 classmark II 中都規(guī)定了Power Capability 和 Power Class的對應(yīng)關(guān)系,希望對你有所幫助:
RF power capability (octet 2)
When GSM 450, GSM 480, GSM 710, GSM 750, T-GSM 810, GSM 850, GSM 900 P, E [or R] band is used (for exceptions see 3GPP TS 44.018 [84]), the MS shall indicate the RF power capability of the band used (see table):
When UMTS is used, a single band GSM 450, GSM 480, GSM 710, GSM 750, T-GSM 810, GSM 850, GSM 900 P, E [or R] MS shall indicate the RF power capability corresponding to the (GSM) band it supports (see table). In this case information on which single band is supported is found in classmark 3.
Bits(Power Capability)
321
000class 1
001class 2
010class 3 Power Class
011class 4
100class 5
All other values are reserved.
When the GSM 1800 or GSM 1900 band is used (for exceptions see 3GPP TS 44.018 [84], sub-clause 3.4.18), the MS shall indicate the RF power capability of the band used (see table):
When UMTS is used, a single band GSM 1800 or GSM 1900 MS shall indicate the RF power capability corresponding to the (GSM) band it supports (see table). In this case, information on which single band is supported is found in classmark 3.
Bits(Power Capability)
321
000class 1
001class 2 Power Class
010class 3
All other values are reserved.
When UMTS is used, an MS not supporting any GSM band or a multiband GSM MS shall code this field as follows (see table):

321
111RF power capability is irrelevant in this information element.
All other values are reserved.
NOTE 2: The requirements for the support of the A5 algorithms in the MS are specified in 3GPP TS 43.020 [13].
