The invention provides an access-attempting emission method that excludes the influence of other modes in dual-mode mobile phone, which comprises the following steps: (1) when the dual-mode mobile phone is preparing the access attempt of mode 1, the mode 1 module real-time acquires the frequency range of the emission signal channel of mode 2 module in the emission status, and determines the leakage power from mode 1 to mode 2; (2) the mode 1 module measures the overall power of the forward link received within the whole frequency band, and figures out the average output power according to thestandard of mode I; (3) the calculated average output power minus the power leaked from mode 2 to mode I obtains the final average emission power.
Description
Access trial transmission method for dual-mode mobile phones that excludes the influence of other standard transmissions technical field The invention belongs to the field of mobile communication, and in particular relates to a method for eliminating the influence of transmission power of other systems when a dual-mode mobile phone determines the transmission power of an access test. Background technique A dual-mode mobile phone refers to a mobile phone that contains two communication protocols. As far as the current commercial network is concerned, there can be a combination of wireless communication networks such as GSM, CDMA2000, PHS, TDSCDMA, WCDMA, and WLAN. Although the operating frequency bands of these networks are mostly different, in actual applications, there will be mutual interference of radio frequency bands, especially in dual-mode or multi-mode mobile phones, especially for dual-mode mobile phones using GSM900 and CDMA800 as the working network, due to the t...
