Description

  The present invention relates to an internal polling process for searching for an internal operation request in a mobile phone, and more particularly to a mobile phone that performs an intermittent operation of this polling process.

  There is a mobile communication system that performs intermittent reception processing of whether there is an incoming call from a base station to a mobile station and cell search in synchronization with the timing of the mobile communication telephone network (see, for example, Patent Document 1).

  In the mobile communication system of Patent Document 1, the interval of the intermittent reception process is arbitrarily changed based on the current time, the incoming call frequency, and the radio wave condition. This achieves both reduction in power consumption during intermittent reception by the mobile station and improvement in incoming call response.

  In addition, there is a mobile phone that intermittently operates an internal polling process for searching for an internal operation request of a mobile phone, instead of an intermittent reception process of an incoming call from a base station or a cell search as in Patent Document 1. This intermittent operation is performed at a constant cycle.

JP 2000-261364 A (pages 5 to 6, FIG. 6, FIG. 7, FIG. 11)

  By the way, in the mobile communication system of the prior art described in Patent Document 1 described above, there is no description regarding polling processing for searching for an internal operation request.

  Also, the conventional internal operation polling process is performed at a constant cycle, and if the intermittent operation cycle is lengthened in order to further reduce power consumption, a transmission operation request for accessing the mobile communication telephone network is generated. At times, there is a problem that the access timing to the mobile communication telephone network is delayed and usability is deteriorated.

  The present invention has been made to solve the above-mentioned problems. Regarding the polling process, the intermittent operation cycle is lengthened to further reduce power consumption, and the access timing to the mobile communication telephone network is delayed. It is another object of the present invention to provide a mobile phone that does not deteriorate usability.

  In order to achieve the above object, a mobile phone of the present invention generates a network synchronization timing signal having a constant period, a timer that generates a polling timing signal having a variable period in synchronization with the network synchronization timing signal, An operation means for accepting a call request operation; a wireless processing means for performing wireless processing for wireless communication with the mobile phone network by periodically wake-up by the network synchronization timing signal; and a wake-up by the polling timing signal. Polling whether or not a call request is made by the operation means, and if there is a call request, a polling processing means for instructing the wireless processing means to make a call and a display unit for performing main display is in an ON state The polling timing signal has a variable period as a first period, and when the display unit is in an off state, Characterized by comprising a control means for setting a variable period of the timing signal to the longer second period than the first period.

  According to the present invention, with respect to polling processing, the period of this intermittent operation is lengthened to further reduce power consumption, and a mobile phone without degradation in usability without delaying access timing to the mobile communication telephone network is provided. It becomes possible.

The state transition diagram of the control part of the mobile telephone which concerns on the Example of this invention. The time chart of the mobile telephone which concerns on the Example of this invention.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 to 3 show an embodiment in which the present invention is applied to a mobile phone, FIG. 1 is a block diagram of the mobile phone, FIG. 2 is a state transition diagram of a control unit of the mobile phone, and FIG. It is a chart.

  FIG. 1 is a block diagram of a mobile phone. The main part of the cellular phone includes an LCD 1, a folding switch 2, a key 3, an RTC (Real Time Clock) 4, a timer 5, a control unit 6, a radio unit 7, an antenna 8, and the like. Further, the control unit 6 includes a UI (User Interface) processing unit 61, a polling processing unit 62, and a wireless processing unit 63.

  The control unit 6 has a “wake-up (wake-up) / sleep state”. The predetermined input signal to the control unit 6 causes the control unit 6 to be in a wake-up state, and one or more of the UI processing unit 61, the polling processing unit 62, and the wireless processing unit 63 perform processing. When all the processes of the UI processing unit 61, the polling processing unit 62, and the wireless processing unit 63 are completed, the control unit 6 enters a sleep state and enters a power saving state.

  The “wake-up / sleep state” has various general-purpose forms for the purpose of power saving. For example, a form in which “power supply is turned on / off”, a form in which “high / low operation frequency is switched”, “ There is a form of performing “switching of all function operations / partial function operations”. Detailed description of these general-purpose forms will be omitted.

  The LCD 1 is a main display unit arranged at a position that can be seen when the lid of the foldable mobile phone is opened. After the control unit 6 wakes up, various display controls are performed by the UI processing unit 61. In the case of a non-foldable mobile phone, main display means for performing main display may be used.

  The folding switch 2 is a switch that detects the folded state of the lid of the folding mobile phone. When the lid is opened, the folding switch 2 sends a signal 2a to the control unit 6 to wake up the control unit 6. Then, the UI processing unit 61 starts operation.

  The key 3 is an input means for a user (user) operation. When the key operation is performed, the key 3 is sent to the control unit 6 to wake up the control unit 6. Then, the UI processing unit 61 starts to operate.

  The RTC 4 performs a clock operation, an alarm time measurement, etc., and when the alarm time elapses, the RTC 4 sends a signal 4a to the control unit 6 to wake up the control unit 6. Then, the UI processing unit 61 starts to operate.

  The timer 5 sends out a polling timing signal 5a to the control unit 6 at a cycle of 1.25 seconds or 5.12 seconds to wake up the control unit 6 periodically. Then, the polling processing unit 62 starts to operate. The period of the polling timing signal 5a is set from the UI processing unit 61 by the timer setting signal 6b.

  The wireless processing unit 62 of the control unit 6 turns on the wireless unit 7 when performing transmission / reception with the base station of the mobile communication network. And when transmitting to a base station, the control part 6 sends out the transmission signal 6c to the radio | wireless part 7. FIG. The radio unit 7 performs processing such as D / A conversion and up-conversion on the transmission signal 6 c to generate a radio signal and sends it to the antenna 8. The antenna 8 transmits a radio signal to the base station.

  When receiving from the base station, the radio signal transmitted from the base station is received by the antenna 8 and transmitted to the radio unit 7. The wireless unit 7 performs processing such as down-conversion and A / D conversion on the received wireless signal, and sends the converted signal 7 a to the wireless processing unit 63. The wireless processing unit 63 extracts the timing of paging or the like for the base station to call the mobile phone, and stores it in the timer 5 for synchronization with the base station.

  The timer 5 sends this timing as a network synchronization timing signal 5b to the control unit 6 to wake up the control unit 6 periodically. Then, the wireless processing unit 63 periodically starts operation in synchronization with a paging signal for calling the mobile phone from the base station, and performs standby processing such as calling to the mobile phone and cell search processing. When there is a call to the mobile phone, the wireless processing unit 63 sends an incoming call request to the polling processing unit 62.

  2 is a state transition diagram of the control unit 6, FIG. 2A is a state transition diagram of the wake-up / sleep state of the control unit 6, and FIG. 2B is an operation start / stop of the UI processing unit 61. FIG. 2C is a state transition diagram of operation start / stop of the polling processing unit 62, and FIG. 2D is a state transition diagram of operation start / stop of the wireless processing unit 63. Each of them shows the main state transition conditions. The state transition of each part will be described with reference to FIG.

  In FIG. 2A, the condition for transitioning the control unit 6 to the wake-up state is the condition for starting the operation of the UI processing unit 61 shown in FIG. 2B or the polling processing unit 62 shown in FIG. This is a condition for starting the operation, or a condition for starting the operation of the wireless processing unit 63 shown in FIG. That is, the OR condition of these conditions. The condition for transitioning the control unit 6 to the sleep state is when all of the UI processing unit 61, the polling processing unit 62, and the wireless processing unit 63 are stopped.

  In FIG. 2B, the conditions for transitioning the UI processing unit 61 to the operation start state are a transmission instruction from the polling processing unit 62, various conditions for turning on the LCD 1, and the like. The conditions for turning on the LCD 1 are opening the lid of the foldable mobile phone, key operation, elapse of alarm time, and the like. The conditions for transitioning the UI processing unit 61 to the stop state include various conditions for turning off the LCD 1. The various conditions for turning off the LCD 1 are closing the lid of the foldable mobile phone, operating, time-out after display, and the like.

  When the operation starts, the UI processing unit 61 checks the opening of the folding cellular phone, confirms key operation, alarm time elapses, etc., and activates the user interface that is a process corresponding to the user (user) with any of the conditions. When it is determined that it is necessary to turn the LCD 1 on, the LCD 1 is turned on to perform a predetermined display. When the LCD is turned on, the polling timing cycle is set to 1.28 seconds in the timer 5 by the timer setting 6b. Accordingly, the timer 5 generates a polling timing signal 5a at a cycle of 1.28 seconds and sends it to the control unit 6.

  In addition, the UI processing unit 61 may time out without causing any processing such as closing the lid of the foldable mobile phone, operation or display, and invalidate the user interface corresponding to the user (user). When determined, the LCD 1 is turned off. When the LCD is turned off, the polling timing cycle is set to 5.12 seconds in the timer 5 by the timer setting 6b. Accordingly, the timer 5 generates a polling timing signal 5a at a cycle of 5.12 seconds and sends it to the control unit 6.

  In FIG. 2C, the condition for transitioning the polling processing unit 62 to the operation start state is the polling timing signal 5a from the timer 5 every 1.25 seconds or 5.12 seconds. The stop condition of the polling processing unit 62 is the end of the processing of the polling processing unit 62 itself.

  When the polling processing unit 62 starts, the polling processing unit 62 checks the transmission request from the UI processing unit 61 and the wireless processing unit 63 and, if there is a transmission request, issues a transmission instruction to the UI processing unit 61 and the wireless processing unit 63. Then, the polling processing unit 62 itself ends the process and stops.

  In FIG. 2D, the condition for transitioning the wireless processing unit 63 to the operation start state is the network synchronization timing signal 5 b from the timer 5 every 5.12 seconds. The stop condition of the wireless processing unit 63 is the end of processing of the wireless processing unit 63 itself.

  When the operation starts, the wireless processing unit 63 turns on the wireless unit 7 and performs wireless control with the base station.

  FIG. 3 is a time chart of the mobile phone. The mobile phone is in a standby state, and the timer 5 generates the network synchronization timing signal 5b at the timings T1, T5, T9, and T13 in a cycle of 5.12 seconds in accordance with paging from the base station. The wireless processing unit 63 starts operation by T1 of the network synchronization timing signal 5b, first turns on the wireless unit 7, performs predetermined wireless processing, and turns off the wireless unit 7 when processing is completed. The part 63 itself is stopped. This is repeated with T5, T9, and T13.

  The UI processing unit 61 is in an operating state, and it is assumed that the LCD 1 is in the on 1a state according to the on condition of the LCD 1. Accordingly, the polling timing signal 5a is generated at a cycle of 1.28 seconds as shown at timings T1 and T2. The timer 5 synchronizes this polling timing signal 5a with the network synchronization timing signal 5b, and T1 of the polling timing signal 5a and T1 of the network synchronization timing signal 5b are synchronized.

  The polling processing unit 62 first starts an operation in response to T1 of the polling timing signal 5a, and checks outgoing requests from the UI processing unit 61 and the wireless processing unit 63. Then, if there is this transmission request, the polling processing unit 62 issues a transmission processing instruction to the UI processing unit 61 and the wireless processing unit 63, and then the polling processing unit 62 itself stops. If there is no call request, the polling processing unit 62 stops without doing anything. This is repeated for each polling timing signal 5a.

  Next, it is assumed that the lid closing 2a-1 of the folding cellular phone occurs between T2 and T3 of the polling timing signal 5a. When the lid closing 2a-1 occurs, the UI processing unit 61 turns off the LCD 1 and sets the period of the polling timing signal 5a to 5.12 seconds. The timer 5 is in the process of generating T3 with a period of 1.28 seconds at that time, and when T3 ends, the polling timing signal 5a is generated with a period of 5.12 seconds.

  Therefore, the timer 5 should originally output at T7, but if there is T5 of the network synchronization timing signal 5b before T7, it is given priority and synchronized with T5 of the network synchronization timing signal 5b. Then, T5 of the polling timing signal 5a is generated. Thereafter, the polling timing signal 5a operates at a cycle of 5.12 seconds and is generated at T9 and T13.

  From another viewpoint, the 5.12 second period between T3 and T7, which is the original timing of the polling timing signal 5a, is not an absolute interval but a maximum interval, and between T3 and T7, If a high-priority signal such as T5 of the network synchronization timing signal 5b is generated, it can be said that priority is given to that and the interval of the polling timing signal 5a is shortened to an interval of 2.56 seconds between T3 and T5.

  Therefore, when the LCD 1 is in the OFF state, the polling timing signal 5a has a 5.12 second period synchronized with the network synchronization timing 5b with the 5.12 second period as the maximum interval and giving priority to the network synchronization timing 5b. .

  Next, it is assumed that the lid opening 2a-2 of the folding cellular phone occurs at an arbitrary timing between T9 and T13 of the polling timing signal 5a. The UI processing unit 61 is in a stopped state after the lid closing 2a-1, but starts to operate when the lid is opened 2a-2.

  When the operation starts, the UI processing unit 61 turns on the LCD 1 and sets the period of the polling timing signal 5a to 1.28 seconds. The timer 5 is in the process of generating T13 with a cycle of 5.12 seconds at that time, and when T13 ends, thereafter, the polling timing signal 5a is generated with a cycle of 1.28 seconds.

  Accordingly, after T13, the timer 5 generates T14 and T15 having a period of 1.28 seconds as the polling timing signal 5a.

(power consumption)
The power consumption will be described below. The polling processing unit 62 operates at the timings T1 to T3, T5, T9, and T13 to T15 of the above-described polling timing signal 5a. The UI processing unit 61 operates while the LCD 1 is on. The wireless processing unit 63 operates at the timings T1, T5, T9, and T13 of the network synchronization timing signal 5b.

  Therefore, the wake-up state of the control unit 6 is an OR state during operation of the polling processing unit 62, the UI processing unit 61, and the wireless processing unit 63. Therefore, when the LCD 1 is in the on state, the control unit 6 continues to wake up, and the power consumption of the control unit 6 is large. When the LCD 1 is in the off state, the operation of the polling processing unit 62 is fixed at a cycle of 1.28 seconds in the conventional technique. However, in this embodiment, the cycle is approximately 5.12 seconds, and the LCD 1 is in the off state. The power consumption at the time can be greatly reduced.

  In general, even when the mobile phone is in a power-on state, the number of times when the lid is closed and the LCD 1 is in an off state due to standby or the like is much higher. Therefore, the standby time of the battery of the mobile phone can be extended by greatly reducing the power consumption when the LCD 1 is in the off state.

(Usability)
Usability is described below. First, when the LCD 1 is in the on 1a state, the polling processing unit 62 operates at a cycle of 1.28 seconds of T1, T2, and T3. The polling processing unit 62 checks a transmission request from the UI processing unit 61 by a user operation or a transmission request from the wireless processing unit 63 at a cycle of 1.28 seconds. That is, an instruction for the transmission process is issued to the UI processing unit 61 and the wireless processing unit 63 within 1.28 seconds at the latest from the transmission request. That is, the response to the call request is fast.

  Next, when the lid closing 2a-1 occurs, the LCD 1 is turned off 1b, and the polling processing unit 62 operates at a cycle of 5.12 seconds of T5, T9,. However, since the timings T5 and T9 are synchronized with the network synchronization timing 5b, the incoming request from the wireless processing unit 63 operating at the network synchronization timing 5b is checked without delay. With an early response, it is possible to issue an incoming call processing instruction to the UI processing unit 61 and the wireless processing unit 63. Therefore, the present invention has no influence on this incoming call processing.

  Further, when the lid opening 2a-2 occurs at an arbitrary timing between T9 and T13 by a user operation while the LCD 1 is in the off 1b state, the LCD 1 is immediately turned on. At this time, the polling timing signal T13 is generated at the longest after 5.12 seconds from the opening of the lid 2a-2. However, the user does not make a call suddenly by opening the lid 2a-2, and then makes a call request after performing a key operation for making a call. In addition, the LCD 1 is in the ON state 1c not only in the lid opening 2a-2, but there are conditions such as key operation and alarm time that have passed. Make a call request after performing key operation for.

Therefore, when a transmission request from the UI processing unit 61 is generated, the polling processing unit 62 has already been operating at a period of 1.28 seconds after T13. Therefore, the polling processing unit 62 can check the transmission request by the user operation without delay, and can issue the transmission processing instruction to the UI processing unit 61 and the wireless processing unit 63 with an early response. As described above, according to the embodiment, when the LCD 1 is in the OFF state, the operation cycle of the polling processing unit 62 is delayed, the battery standby time is lengthened, and the transmission process is performed with good response to the transmission request. Can do.

  The period of the polling timing signal 5a is 1.28 seconds or 5.12 seconds. However, it is not necessary to fix the period, and it is sufficient that the long and short relations are matched.

  The UI processing unit 61, the polling processing unit 62, and the wireless processing unit 63 are inside the control unit 6, and the control unit 6 depends on the OR condition of the operations of the UI processing unit 61, the polling processing unit 62, and the wireless processing unit 63. However, the UI processing unit 61, the polling processing unit 62, and the wireless processing unit 63 may be independent of each other and have a “wake-up / sleep control” state.
