Embodiment
The relevant electricity saving method that is used for the mobile communication device of wireless communication network of the present invention, please be earlier with reference to enforcement environment schematic diagram shown in Figure 1, wherein, in wireless communication network 200, include an action device 10 and a plurality of base station 207 these wireless communication network 200 and can be a GSM, PHS, or 3G (WCDMA, CDMA 2000) system, this action device 10 is for example to be a mobile phone 11, after mobile phone 11 starts, to carry out existing communication protocol and carry out initializing set, and the base station 20 of mobile phone 11 present positions is contained in searching, to set up the electric property coupling of wireless mode, register and authenticate to wireless communication network 200 according to this.After registration is finished, mobile phone 11 will enter standby mode and keep being electrically coupled to this base station 20 with wireless mode, and can further start a dormancy mechanism to reduce the consumption of electric power, and as incoming call or user when desiring to call, mobile phone 11 can see through base station 20 and send a telegram here immediately or give orders or instructions program.And mobile phone 11 also continue to see through that navigator's channel 15 (pilot channel) or one section are loaded in pilot signal (pilot signal) in the data and the power of the wireless signal that detecting is sent by this base station 20, when moving to regional that another base station 20 contained with the zone of being contained by this base station 20 when mobile phone 11, mobile phone 11 will detect the weakening of power of this wireless signal and cancel dormancy mechanism and and then carry out a program of searching new base station again, can keep being electrically coupled to new base station 20 with wireless mode.
Fig. 2 shows the flow chart of an embodiment of the electricity saving method of the mobile communication device that is used for wireless communication network of the present invention, wherein, in step S201, mobile phone 11 is under the standby mode or under standby mode and startup dormancy mechanism, be to keep being electrically coupled to base station 20, and also continue to detect the power of the wireless signal that is sent by this base station 20 through navigator's channel 15 with wireless mode.In step S202, as the power of the wireless signal detected less than a default power threshold Tp, signal quality between expression base station 20 and the mobile phone 11 is low excessively, its reason may for mobile phone 11 away from this base station 20, or temporarily be subjected to the change of environment and influence that (for example the cellie runs into and temporarily appears at the barrier on the line communication or take elevator, or enter cavern, situations such as basement), for avoid signal quality because of the influence of the temporary transient change that is subjected to environment cause mobile phone 11 immediate cancel dormancy mechanisms or and then search new base station again, step S203 carries out a delay routine, so that behind this mobile phone 11 delays one Preset Time, again detect the power of the wireless signal that is sent by this base station 20 again and judge its size (step S204), as this moment the wireless signal detected power still less than this default power threshold Tp, mobile phone then cancel dormancy mechanism or and then carry out the program (step S205) search new base station again, otherwise, as this moment the wireless signal detected power greater than this default power threshold Tp, represent that signal quality between previous mobile phone 11 and the base station 20 just temporarily is subjected to the change of environment and influences, and this temporary factor has disappeared, therefore, mobile phone 11 need not be cancelled dormancy mechanism and carry out and search the program of new base station again, and can save expending of electric power.
Fig. 3 shows the flow chart of another embodiment of the electricity saving method of the mobile communication device that is used for wireless communication network of the present invention, wherein, in step S301, mobile phone 11 is under holding state, or under standby mode and startup dormancy mechanism, be to keep being electrically coupled to base station 20 with wireless mode, and the power that also continues to see through navigator's channel 15 and detect the wireless signal that is sent by this base station 20, and further calculate the slope value (step S302) of the variation of representing this radio signal power, as shown in Figure 4, the power of the wireless signal that mobile phone 11 is detected when time point T (n) and T (n+1) is respectively P (n) and P (n+1), then can obtain a slope value S=|P (n+1)-P (n) | ÷ (T (n+1)-T (n)), this slope value S promptly represents the variable power situation of the wireless signal on time T (n)-T (n+1), generally speaking, if the variable power of wireless signal not quite (for example diminishes gradually, slope value S is little), represent that then mobile phone 11 is very likely gradually away from base station 20, otherwise, (for example diminish suddenly if the variable power of wireless signal is very big, slope value S is big), represent then that mobile phone 11 is very likely fixed temporarily to be subjected to the change of environment and to influence.
Please refer to shown in Figure 3 again, in step S303, as the power of the wireless signal detected less than a default power threshold Tp, signal quality between expression base station 20 and the mobile phone 11 is low excessively, its reason may for mobile phone 11 away from this base station 20, or fixed temporarily be subjected to the change of environment and influence, for avoid signal quality because of the influence of the temporary transient change that is subjected to environment cause mobile phone 11 immediate cancel dormancy mechanisms or and then search new base station again, step S304 judges that whether this slope value S is greater than a default slope critical value Ts, as denying, the variable power of expression wireless signal is little, so mobile phone 11 is very likely for gradually away from base station 20, thereby carry out the program (step S307) search new base station again, otherwise, judge that as step S204 this slope value S is greater than default slope critical value Ts, the variable power of expression wireless signal is very big, so the signal quality that mobile phone 11 and base station are 20 very likely is temporarily to be subjected to the change of environment and to influence, therefore, not immediate cancel dormancy mechanism or and then carry out the program search new base station again, but carry out a delay routine (step S305) earlier, so that behind these mobile phone 11 delays one preset time T d, again detect the power of the wireless signal that is sent by this base station 20 again and judge its size (step S306), as this moment the wireless signal detected power still less than this default power threshold Tp, mobile phone then cancel dormancy mechanism or and then carry out the program (step S307) search new base station again, otherwise, as this moment the wireless signal detected power greater than this default power threshold Tp, represent that signal quality between previous mobile phone 11 and the base station 20 just temporarily is subjected to the change of environment and influences, and this temporary factor has disappeared, therefore, mobile phone 11 need not be cancelled dormancy mechanism or carry out and search the program of new base station again, and can save expending of electric power.
The slope value S that abovementioned steps S302 calculated is a variation situation of representing radio signal power, generally speaking, the bigger expression environment of the slope value S that calculates has huge variation suddenly, for example the cellie enters in the elevator, signal power can diminish suddenly, so the delay routine of step S305 need postpone long time T d, otherwise, the variation of the less expression environment of the slope value S that calculates is comparatively gentle, the cellie countryside of driving a vehicle for example, because distance increases gradually between running gear and base station, signal power also reduces gradually, so the delay routine of step S305 only need postpone short time T d.Thereby, in the present embodiment, the delay routine of step S205 required time of delay Td length be the size that is positively correlated with this slope value S, to obtain best effect.
The foregoing description only is to give an example for convenience of description, and the interest field that the present invention advocated should be as the criterion so that claim is described certainly, but not only limits to the foregoing description.
