Abstract

The battery life of a mobile communication terminal which performs activities at particular time intervals, or slots, is extended by controlling a slot cycle according to a remaining capacity of the battery. The terminal has a slot cycle index table for storing a plurality of reference levels and their corresponding slot cycle indexes. As a slot cycle change mode is set, the terminal detects the battery level in a prescribed level check cycle and compares the detected battery level with the reference levels in sequence. If the detected battery level is higher than a selected one of the reference levels, the terminal sets the slot index to a value corresponding to the selected reference level. Further, the terminal sets the slot cycle index corresponding to a longest slot cycle, when the detected battery level falls outside of a reference level range.

The present invention relates to a kind of mobile communication terminal, particularly relate to a kind of limited battery operation time method that is used to prolong mobile communication terminal.
The mobile subscriber can comprise cellular telephone, PCS (personal communication service) phone, CT-2 (cordless telephone generation 2) etc. with the mobile communication terminal of itself and other telex network.Mobile communication terminal is at the signal that in the circulation of regulation search from base station receive definite according to time slot cycle index (slot cycle index).The time slot cycle index is provided with in the production process of mobile communication terminal, and the user can pass through man-machine interface (MMI) changing function time slot cycle index.Usually, when the user is in can not be to a plurality of hours situation of battery charge the time, the user just uses the MMI function, to prolong the battery operation time.But the user should detect battery status, all will control the time slot cycle index with the MMI function at every turn.In addition, even the user detects battery status, he should understand the notion of time slot cycle index well, so that according to battery status control time slot cycle index.
Therefore the purpose of this invention is to provide a kind of residual capacity and control the method for the time slot circulation of mobile communication terminal according to battery.
For achieving the above object, provide a kind of battery operation time method that is used to prolong mobile communication terminal.Mobile communication terminal has the time slot cycle index table that is used to store a plurality of reference values and corresponding time slot cycle index thereof.When time slot varying cyclically pattern was set, terminal detected battery level in the battery level check circulation of regulation, and seriatim detected battery level and reference level is compared.When if detected battery level is higher than one of selected reference level, terminal is set to the time slot cycle index value of the reference level of corresponding selection.
In addition, when detected battery level exceeded the reference level scope, terminal was set to corresponding the longest time slot circulation to the time slot cycle index.
Consult the detailed description of accompanying drawing, above and other objects of the present invention, feature and advantage will become very obvious, in the accompanying drawing:
Fig. 1 uses the block diagram that prolongs the battery operation time device in the mobile communication terminal of the present invention; With
Fig. 2 is the flow chart that is used to prolong the battery operation time method of mobile communication terminal according to embodiments of the invention explanations.
The preferred embodiments of the present invention are described with reference to the accompanying drawings.
Fig. 1 represents to be used for prolonging the block diagram at mobile communication terminal battery operation time device.With reference to figure 1, rechargeable battery 10 provides operating voltage to mobile communication terminal, and modulus (A/D) converter 20 is transformed to digital voltage signal to the analog voltage signal of battery 10.CPU (CPU) 30 is according to the whole work that is stored in the control program control mobile communication terminal in the memory 40.In addition, CPU30 is provided with the time slot cycle index according to the digital voltage signal of the battery 10 that receives from A/D converter 20.Control program and various other data of memory 40 storage CPU30.Particularly, memory 40 has the time slot cycle index table that is used for storage time slots cycle index and corresponding reference level thereof, and is as shown in table 1.
＜table 1 〉
The time slot cycle index 0 ?1 ?2 ?3 ?4 ?5 ?6 ?7
Reference level (V) 7.2 ?6.9 ?6.7 ?6.5 ?6.3 ?6.1 ?5.9 ?5.7
In the table 1, though be expressed as physical values, reference level is the numerical data that can use software processes.In addition, 7.2V that is limited by reference level and the voltage range between the 5.7V mean the operating voltage range that mobile communication terminal can operate as normal.
Fig. 2 is the flow chart that is used to prolong the battery operation time method of mobile communication terminal according to the embodiment of the invention.In Fig. 2, CPU30 detects battery level at regular intervals when the time slot cycle index is set, and according to detected battery level control time slot cycle index.
Referring to Fig. 2, CPU30 determines in step 210 whether the user uses the keyboard (not shown) of mobile communication terminal that time slot varying cyclically pattern has been set.If determine that the user has been provided with time slot varying cyclically pattern, then in step 212, CPU30 checks whether battery level check circulation arrives, so that check the state of battery 10 at regular intervals.If determine that in step 212 battery level check circulation arrives, then in step 214, CPU30 is by reading the level that detects battery 10 from the digital voltage signal of A/D converter 20 outputs of the analog voltage signal of conversion battery 10.In case the detection battery level, in step 216, it is zero that CPU30 is provided with count value n, so that seriatim detected battery level and reference level are compared.
After this, in the beginning of initial reference level Lref_0, CPU30 compares detected battery level and reference level seriatim, so that appropriate time slot cycle index is set in step 218 to 226.Specifically, in step 218, CPU30 compares detected battery level with initial reference level Lref_0 (that is the 7.2V in the table 1) corresponding to the time slot cycle index (that is the index in the table 1 0) of the circulation of crack the most in short-term.Result as a comparison, if determine that detected battery level is equal to or less than initial reference level Lref_0, then in step 220, CPU30 determines whether reference level Lref_0 is minimum reference level (that is the 5.7V in the table 1).If determine that reference level Lref_0 is not minimum reference level, then CPU30 increases by 1 to count value n, to select next reference level Lref_1 in step 222, turns back to step 218 then.Then, in step 218, CPU30 compares detected battery level and reference level Lref_1.Result as a comparison, if detected battery level is higher than reference level Lref_1, then CPU30 reads time slot cycle index " 1 " corresponding to reference level Lref_1 (that is the 6.9V in the table 1) from memory 40, so that in step 224, the circulation of time slot index is set to " 1 ".Yet if determine that in step 220 reference level Lref_n is minimum reference level, CPU30 reads the time slot cycle index " 7 " corresponding to the longest time slot circulation, so that the time slot cycle index is set to " 7 ".
Briefly, if be higher than reference level at the detected battery level of step 218, then CPU30 is at the time slot cycle index of step 224 setting corresponding to reference level.Yet if detected battery level is equal to or less than reference level, CPU30 increases by 1 in step 220 and 222 with count value n, up to reference level become be lower than detected battery level till.
Referring to table 1, be 6.4V if detect battery level, then CPU30 compares the reference level Lref_0-Lref_4 of the detected battery level of 6.4V and 7.2V, 6.9V, 6.7V, 6.5V and 6.3V one by one.When the reference level of the battery level of 6.4V and 6.3V relatively the time, CPU30 determines that battery level is higher than reference level Lref_4, and the time time slot cycle index be set to " 4 " corresponding to the reference level Lref_4 of 6.3V.
Should be understood that, depend on that battery level detects the function of circulation although the foregoing description only shows, turn back to step 212 by making step 224 or step 226, above-mentioned functions also can detect circulation at each battery level and repeat.
As mentioned above, mobile communication terminal of the present invention can be realized minimum battery consumption according to battery level by control time slot cycle index, in amount, helps the prolongation of limited battery operation time.
