Fig. 1 is the flow chart of the detection method embodiment one of terminal capability of the present invention, and as shown in Figure 1, present embodiment provides a kind of detection method of terminal capability, can specifically comprise the steps:
In the present embodiment, after the call setup at terminal, start the detection to the terminal, the terminal here can be specially mobile phone, and present embodiment is specially the SAIC mobile phone and detects, and promptly whether detection of handset is SAIC problem mobile phone.This step is that downlink data and the virtual pulse after will encoding in the base station carried out by Bit Interleave; The downlink data at terminal to be detected is mail to according to normal flow completion coding in the base station; Before sending the data to logic; Interleaving treatment is carried out in downlink data and virtual pulse behind the coding, and the virtual pulse here can be specially the virtual pulse of SAIC (Dummy Burst).
Particularly, downlink data after above-mentioned will the coding in the present embodiment and virtual pulse are carried out can being specially by the step of Bit Interleave: downlink data after will encoding and virtual pulse are carried out by Bit Interleave, wherein: the downlink data behind the said coding accounts for even bit; Said virtual pulse accounts for strange bit, and the form of said virtual pulse is following: 0x76f8,0x9283; 0x4483; 0xc7c0,0xd1d1,0x9751; 0xe662; 0x7cbc, 0xafa4,0x00d6.
Modulation treatment is carried out to the data after interweaving in the base station, and present embodiment specifically can adopt Alpha (Alpha) quarternary phase-shift keying (QPSK) (Quadrature Phase Shift Keying; Hereinafter to be referred as: QPSK) modulation system is modulated downlink data, and the data after the modulation treatment are sent to the terminal, generates upstream data to trigger said terminal.In the present embodiment; The terminal is when upstream data is sent in the base station; This upstream data can receive the influence of the downlink data after the modulation treatment that the base station issues; Owing to the interleaving treatment of this downlink data process with the particular virtual pulse; Triggering terminal can send to the base station with the upstream data of reflection terminal self problem; The base station is the frequency deviation of sense terminals exactly just; And the upstream data that send at the terminal in the prior art possibly can't really reflect the problem at terminal, can't realize exactly that therefore frequency deviation detects.
Accomplish after the transmission of the downlink data at terminal when the base station, at up direction, the upstream data that the base station receiving terminal sends carries out frequency deviation to upstream data and detects, and comes the tenability at terminal is detected according to the frequency deviation testing result.If promptly the terminal produces bigger frequency deviation value after receiving the downlink data that sends the base station, then the upstream data that sends through the terminal of base station detects frequency deviation seriously the time, shows that this terminal is SAIC problem terminal, and promptly SAIC is not supported at this terminal.If the terminal does not produce frequency deviation, or the frequency deviation value that produces is less, and then the upstream data that sends through the terminal of base station detects frequency deviation when light, shows that this terminal is the non-problem of SAIC terminal, and promptly SAIC is supported at this terminal.
Particularly, present embodiment can specifically adopt automatic frequency control (Automatic Frequency Control; Hereinafter to be referred as: AFC) algorithm comes the upstream data that send at the terminal is carried out the frequency deviation detection.Because the SAIC testing process in the present embodiment is after the call setup at terminal, to initiate, then the initial frequency deviation of AFC algorithm can be made as 0.
More specifically; The above-mentioned upstream data that said terminal is sent in the present embodiment carries out frequency deviation and detects; The step that the tenability at said terminal is detected according to the frequency deviation testing result can comprise the steps: specifically that the upstream data that send at said terminal is carried out frequency deviation to be detected, and record frequency deviation testing result; Detection number of times with preset repeats above-mentioned steps 101-103, obtains the tenability at said terminal according to the frequency deviation testing result that obtains in the said preset detection number of times.
More specifically; When the above-mentioned tenability of obtaining said terminal according to the frequency deviation testing result that obtains in the said preset detection number of times in the present embodiment can comprise the steps: specifically that number of times that the frequency deviation when the said upstream data that in said preset detection number of times, obtains exceeds preset frequency deviation threshold value reaches preset first number threshold value, judge that said terminal does not have the ability of supporting single antenna Interference Cancellation SAIC; The number of times that exceeds preset frequency deviation threshold value when the frequency deviation of the said upstream data that in said preset detection number of times, obtains judges that said terminal has the ability of support SAIC during less than preset second number threshold value.Wherein, second number threshold value can be specially 1, the first number threshold value and also can equate with second number threshold value, perhaps greater than second number threshold value.
