Description of the invention (7) The general understanding of the wireless industry is that wireless mobile phones and base stations Π 2 can also exchange control, housekeeping, and other data or Information. In the exemplary application in FIG. 1, the wireless handset 100 is a processor-based handset, and thus includes a processor 106. The processor 106 controls many functions of the wireless handset 100. Although not shown in the figure, the processor 丨 〇6 is usually combined with memory such as RAM or ROM memory to help store program instructions or other data. The wireless handset 1 shown in Figure 1 also includes Operating system, M software platform that executes one or more applications from 0 to 0. The operating system I 0 8 can also activate the interface between the user or wireless service user and the wireless mobile phone 丨 〇〇 "Although Tushen is not shown, the typical wireless mobile phone usually includes a display screen, a keypad, and other uses Person interface device.

Description of the invention (8) From the example of the application 1 10 above, we know that some applications that may be found in wireless mobile phones 丨 〇〇 may depend on time information in part In order to properly perform its function. Time information can include date and time information ^ For example, for conference planners or calendar applications with alert capabilities to alert users of upcoming meetings or other events scheduled in the application j, 5 usually rely on timing Know when to alert or alert your users. For this application and other time-sensing applications, 1 (), it is important to present and maintain and enable the processor 106 to access a fully accurate real-time timer. However, when using the wireless mobile phone 100 and other portable devices, it may be more difficult to maintain the accuracy of the real-time timing. For example, ‘with a portable device, it ’s foreseeable that users may take their device across the country or even around the world, and therefore to different time zones. If the time counting program on the board is designed as the time zone of the user's home, when the user travels to different time zones, the time counting will not reflect the actual time. In addition, many portable devices, especially many portable devices, are key in terms of cost and power consumption in providing commercializable and competitive products. For its part, * 'for product developers, the cost and power consumption factors associated with providing a fixed and reliable source of time are very important obstacles. Therefore, using this type of portable device, it is foreseeable that the loss of battery power or its t event may cause the portable device to lose its time base.

Specific Examples of Instant Timing The present invention and its various specific embodiments will now be described with respect to the exemplary application aspects presented above with reference to FIG. 1. Fig. 2 shows a block diagram of an exemplary embodiment of the present invention according to a specific embodiment. As described above, the present invention is explained in terms of exemplary application aspects of a wireless handset. After reading this description, those skilled in the art will clearly understand how to implement the present invention in other devices and applications, including hard-wiring and non-banding devices. The example illustrated in FIG. 2 is a wireless portable device 130 that executes one or more time-sensing applications that depend to some extent on a time basis. For example, in the exemplary application described above, the 'wireless strip type device 130' is a wireless handset 100. In the specific embodiment shown in FIG. 2, the device 13o includes a processor 118, a communication interface 12o, and a combined antenna 122, a power source 124, and a real-time generator 1 2 'as described above with reference to the exemplary For the description of the application, the device 130 may use the communication interface 120 and the antenna 122 ′ to communicate voice and / or data information across the radio communication channel to the relay point. 'In the exemplary application shown here, this relay point is called a base station i 2. In the specific embodiment shown in FIG. 2, in order to explain that the relay station can provide the timing information to the wireless device 130, this relay station is marked as the time source 116. < Do n’t ’After reading this description, familiarize yourself with general techniques

O: \ 61 \ 6I768.PTD Page 13 A48 63 4 5. Persons who have explained the invention (ίο) will clearly understand that, depending on the application, the specific implementation of wireless mobile phones and other communication devices or communication stations, the time Sources 1 16 can also be used as base stations 11 2. However, it should be noted that the time information of the specific embodiment is received from an external source, so it is very important that the time source 1 1 6 can provide this time information. In addition, although the communication interface between the time source 1 j 6 and the device 130 is described with a wireless link, the interface may also be provided through a hard-wired interface. Such hard-wired interfaces can be implemented via point-to-point links, networks, and other communication interfaces. The obvious advantage of the wireless link is that it is able to operate the β processor 118 without a physical connection. The processor 118 may be a general-purpose or a special-purpose processor to perform the functionality of the device 130. The processor 118 may be a single-chip or multi-chip processor, and may actually include one or more discrete processors. As described above with reference to Figure i, the 'processor 丨 8 may have an associated operating system' and one or more applications executed by the processor. May include a real-time timing generator 2 6 in order to provide and maintain timing information for one or more applications, where the application may be a time sensing application. A power supply 1 24 may be included to provide power to one or more of the components of the device. As will be explained in more detail below, other functions and capabilities of these * devices and 30 components may be included. Fig. 3 shows the operational prevalence of using the method of the present invention in a portable device. In particular, its processing program shown in FIG. 2 illustrates the operation of the present invention according to a specific embodiment in an exemplary application of the wireless communication handset lj 0. After reading this description, those skilled in the art will clearly understand how to implement the invention in another application or device. Now refer to Figure 3,

448 63 4 V. Description of the invention (11) In step 132, turn on the power of the wireless mobile phone i 0〇. Because the user can bring his wireless handset from one area to another, in step 134, it is first determined whether the mobile phone 100 is located in the active service area. In an exemplary application, the wireless handset 100 determines whether it has received from the base station. 112 signals. If a signal is received, it means that the mobile phone is within the service range. As described in step 1 3 6 ', if the wireless handset is within the service range, it will receive the time update from the base station 11 2. As mentioned above, this time signal may include time and / or date information 'and may be provided to change the accuracy. The time information is received via the communication interface 1220 and provided to the processor 11 &. At step 1 38, the processor 丨 8 provides all or part of the time information to update the real-time timing generator 226. Therefore, 'from the time source 丨 16 (for example, base station 1 1 2) after receiving the time', the timing function in the real-time timing generator 1 2 6 will reset to the current time and start counting from the latest reset time epoch . At step 140, the processor CPlJ may be updated and the current time is maintained by the real-time timing generator. That is to say, the real-time timing generator 丨 26 tracking the current time ′ can provide the current time updated by the date to the timing associated with the processor 1 丨 8. Then 'can show the time on the device display again. In step 1 4 2 /, the current time of the user is provided on the display screen (not shown in Figure 3). This current time can be provided to the display screen of the device by the processor 11 8 „As the current time is received from the source 1 1 6 and This time information is used to update or reset the real-time timing generator 12 6 ', so the internal time information of the device 3 0 (for example,' wireless mobile phone 1 0Q ') can be maintained and updated to determine the desired accuracy.

Page 15 448634 V. Description of the invention (12) For example, if the user travels from one time zone to another, turning on the power of the mobile phone in the new time zone will cause the new time to be received from the time source. This new time allows the real-time timer generator to be reset to the current time zone, thereby updating the device 130 to the current time. The real-time timing generator 丨 2 6 can continue counting from the reset time to maintain the correct current time and provide this time to the processor 1 1 8. If the user brings the device back to the original time zone, or moves to another time zone, a similar process occurs and the time on the board is updated to the current time zone again. In a specific embodiment, the time update function can be performed automatically without user intervention. In another specific embodiment, the user may be notified of the time change before the time change is implemented. This notification can be an audible alarm or a visible message. Before making a change, you can also prompt the user to provide the user with the option to accept or reject the proposed time change. For example, if the user wishes to 'still set their device to hometown' during the travel time zone, then The option to accept or reject suggested time changes is very useful. a In addition, if the real-time timing generator loses its time information for some reason, after the power is turned on, the device (30 will receive the time information from the time source i) 6. The device 13 can use this time information m, Reset the real-time timing benefit 1 26 to the current time. For example, when the device has a complete power failure, it may cause the device 130 to lose its time. As another example, the loss of battery power may cause power failure. 'When powering on the device 13 initially, the device 13 checks whether it is in the active service area, as described in steps 132 and 134.

O: \ 61 \ 61768.PTD Page 16 448634 V. Description of the invention (13) The device 13G can directly rely on and use the time and data of the inbound and outbound protection in the active service area. Because of & Device 1 and device 126 obtain the current time. The processor can use this time when executing the time-sensing application private. As described in step 148, the processor 11 18 may also use a display screen to display the time for the user. In addition, the device 1 30 may provide the user with an audible or visible indicator to indicate the time of the user's device. Just the facts based on internal time. For its part, the user can determine whether the time in the user's current time zone is accurate. For example, 'if the user knows that he has just disembarked and is now in the new time zone', the user may wish that his internal time has been updated. However, if the user receives the device's current time-based instruction or linked time based on the internal time, the user knows that the current time indicated by the device does not reflect the current time zone. For its part, the user may reset the time manually, as explained fully below. FIG. 4 shows a block diagram of an exemplary architecture of a real-time timing generator 226 according to an embodiment of the present invention. Referring now to FIG. 4, the real-time timing cry 126 includes a CPU 206, an alarm clock memory 204, and a timing generator 208. The timing generator 2 08 provides a stable time base for the CPU 2 06. For example, a 'clock generator 208 crystal oscillator type circuit or other precise time circuit provides a stable and fairly accurate timing signal for C P U 2 0 6. The accuracy and correctness of the selected timing generator 208 can be determined according to the term or more than one time. The desired correctness and precise determination of the sensor application private 1 1 0. Other relevant factors in selecting the timing generator 208 include cost, size, and power consumption. For most applications, a crystal timing generator may be suitable as

448 63 4 V. Description of the invention (14) Time base of the timing generator 2 08. The CPU 206 can generally use the time signal provided by the timing generator 208 to track the time. When relaying from a time source 1 16 or other time information source ', the time information provided by the processor 118 can be used to set and reset the CPU 206. Therefore, the CPU 206 uses the time information as the starting point and uses the timing reference signal from the timing generator 208 to track the time from the starting point. It is also possible to install an alarm memory 204 for storing one or more specific warning times in order to trigger an alert for the user. In a specific embodiment, the CPU 20 6 compares the time value stored in the alarm memory 204 with the current time to determine when a warning signal should be generated. If the current time is equal to or exceeds the alarm time, the CPU 2 will trigger the warning processor 11 8 and then the processor] i 8 through the display screen, speaker 3, 1: user interface for the user An audible and / or visible or alarm is provided, and a power saving circuit 21 is also displayed among them. It can be installed, after the main power loss or other termination, 210 is used as the instant timing generator 126 to increase the power saving circuit. The capacitor circuit implements the power saving circuit 210 in order to maintain the two advantages of two simple power recovery. For example, during battery replacement or other forces, this circuit can be used to survive a brief power outage. In another specific embodiment, the power loss period can be implemented by a power-saving circuit 2 10, and the power-saving function M for a longer period of time can be used for a longer period of time. For example, using Battery or I, .. time to hold the device. Longer pieces or devices to implement power-saving circuits

For example, 'users may find that they are in different time zones and there is no signal that can automatically update the timing. In addition, if the current time is lost due to a power failure' or 'if the device is used for the first time and the current time does not appear, and When the system power is turned on within the service range, the user may wish to enter the current time. Fig. 5 is a flow chart showing the operation of a program for manually inputting time information according to an embodiment of the present invention. As described above, when the system is powered on, if a signal is obtained and the signal contains timing information, the timing information will be used to update the device's internal clock, such as (refer to Figure 1) step 232 '242 or effective current time. However, there is an effective step 232 for this function. The system does not have time in the device, and the system waits for the input step timing information. Therefore, and 2 3 3 are explained. If no signal is obtained, but there is time in the real-time timer generator, then the instructions according to steps 24, 4 and 245 will be used.

Before "Phase I reminds you to use 会, the system will wait for a period of time: in the case of no specific implementation, the system will wait for the signal to be obtained: there will be no further prompts. OK, on the other hand, if the user decides not to wait in step 24 6 but to manually turn in time, then in step 248 the user will be given the opportunity to enter the time manually. Such manual input can be performed through a user interface (not shown) installed in the device 130. Alas, the display and can be used to assist the user to manually enter the time. Can also be equipped with other user interface devices. The time entered by the user in step 2 4 9 is used to update or set the real-time timing generator.

5. Description of the invention (21), and generate appropriate alarms for users. Therefore, when the device is in a power-off state, an event can occur and an alarm can be generated. As described above, 'can be operated when the actual time is different from the internal time = device 1 3 0. For example, the following situations may occur. Move the device to a different time zone. The time in this time zone is different from the time set in the previous time zone. As described above, the 'system can use the communication interface to capture the current time and update the real-time timer generator 26' in order to synchronize the device] 30 with the actual time, or the time can be updated manually. In these cases, an alarm may be missing, for example, 'because the new time has passed the alarm time. As far as the update time is concerned, a specific embodiment of the present invention checks a past alarm clock. FIG. 9 is a flow chart showing the operation of a processing program for checking an alarm clock when updating the time in a device according to an embodiment of the present invention. In particular, the processing procedure explained with reference to FIG. 9 is a processing procedure for explaining the update of the current time by receiving time information from a time source 丨 6. After reading this description, those skilled in the art-general technology will clearly understand that no matter what the reason for updating the current time can be, other processing programs can be implemented and used when updating the current time. Referring now to FIG. 8, the time information is received from the time source H6 in step 3 32. As described in steps 3 34 and 3 3 6, if the received time information is the same as the device time, the alarm program can be generated by following the processing procedure described above with reference to FIGS. 7 and 8. On the other hand, as explained in step 334, if the received new time is different from the time according to the real-time timing generator 126, the current time is updated. because

448 63 4 V. Description of the invention (22) is the updated time, so * A direct comparison of the current time with the alarm time may not be enough to generate an alarm. These may actually be later than one or more alarms generated by the device 130 because of the current time. Therefore, in steps 342 and 344, the alarm time is compared with the current time to determine whether the current time is earlier than the alarm time. As explained in steps 344 and 346, if the current time is earlier than the alarm time, it means that the event associated with the alarm has not passed, so the alarm can be generated in a normal manner. However, if the current time is equal to or later than the alarm time, an alarm is generated for the user in step 348, and then the next alarm is retrieved and compared as described in steps 3 50 and 35. While various specific embodiments of the present invention have been described above, it should be understood that these descriptions are presented by way of example only, and are not limited to these examples. Therefore, the spirit and scope of the present invention are not limited to any of the above-mentioned exemplary embodiments, but should be defined according to the following patent application scope and equivalent scope.
