1. A method for controlling temperature of a data card, comprising:
sampling temperature of a protected element on the data card; and regulating data transmission speed of the data card according to the sampled temperature to control the temperature of the data card; wherein the data transmission speed belongs to a speed set {[0,0], [VD1,VU1], . . . , [VDN,VUN], [VD(N+1),VU(N+1)]} which includes N+2 levels, wherein VD is a downlink speed level of the data card, VU is a uplink speed level of the data card, VD(N+1) is a maximum downlink speed level supported by the data card, and the VU(N+1) is a maximum uplink speed level supported by the data card; the uplink speed level increases step by step in ascending order, and the downlink speed level increases step by step in ascending order; the speed is determined by computing according to the following formulae:
VDn=VD(N+1)/2(N-n+1), where n=1, . . . ,N; VUn=VU(N+1)/2(N-n+1), where n=1, . . . ,N. |
