The wireless mobile device of the present invention can be applied to a device having a communication network function such as a mobile phone, a personal digital assistant or a laptop computer. The communication network referred to here is, for example, the second generation Global System for Mobile Communications (GSM) or the third generation of broadband mobile communication system (WCDMA) for performing functions such as wireless communication and transmission of calls, video, and transmission files.

FIG. 1 is a block diagram showing the architecture of a wireless mobile device 10 and a communication network and positioning system connected thereto according to an embodiment of the present invention. The wireless mobile device 10 includes a wireless communication module 20, a positioning module 30, and a storage unit 40. The wireless communication module 20 and the positioning module 30 are electrically connected to the storage unit 40. The function of the wireless communication module 20 is to search the communication network and connect with the communication network to receive or transmit data (such as voice data, video data or other). Positioning module 30 is available for counting Calculating the location information of the location of the wireless mobile device 10, for example, the positioning module 30 can be a device in a Global Positioning System, and calculating the geographic location of the wireless mobile device 10 via satellite signals. The positioning module can also be other types of devices, such as a base station positioning LBS (Location Based Service). The storage unit 40 stores the data from the wireless communication module 20 and the positioning module 30, and the data includes the location data x calculated by the positioning module 30, and the search suggestion table Table 1 (which will be detailed later in FIG. 3). ). The storage unit 40 can be a variety of types of memory, such as flash memory or other forms of erasable stylized read only memory (EEPROM). The wireless mobile device 10 also has other components (not shown) for normal operation of the general wireless mobile device, and is commonly used by those skilled in the communication technology field, such as a microprocessor, a circuit board, a display device, etc. Repeat them.

With continued reference to FIG. 1, the wireless mobile device 10 is wirelessly coupled to the base station 100 of the communication network for transmission of various data. In detail, the wireless communication module 20 of the wireless mobile device 10 includes a transmitting unit 201 and a receiving unit 203. When the wireless communication module 20 is normally connected to the base station 100, the transmitting unit 201 can transmit general data such as voice data or streaming data, and the receiving unit 203 can receive the voice data or the streaming data. The positioning module 30 of the wireless mobile device 10 receives the information transmitted by the transmitting unit 300 (in this embodiment, the satellite) of the positioning system, and calculates the location data of the wireless mobile device 10 according to the received information.

The transmitting unit 201 of the wireless mobile device 10 of the embodiment of FIG. 1 is also adapted to transmit the location data x in the storage unit 40 to the communication network, so that the communication network updates the search recommendation table Table 1 on the network side, that is, this example Chinese search suggestion table Table 1 The recorded data is related to the location data x of the wireless communication device 10 (described in more detail below). In addition, the receiving unit 203 of the embodiment may receive the updated search suggestion table or other search suggestion table from the communication network on a regular or irregular basis instead of the search suggestion table Table 1 originally stored in the storage unit 40. The timing of the occasional update may be when the wireless communication device 10 switches to a new base station at a base station, or when the data in the communication network is updated to a certain extent (for example, 30% of the updated data). When the wireless communication module 20 cannot be connected to any base station (or the connection fails), the location data x calculated by the positioning module 30 of the wireless mobile device 10 is stored in the storage unit 40, and the wireless communication module is simultaneously Group 20 enables the search suggestion table Table 1. That is, when the wireless communication module 20 of the wireless mobile device 10 is unable to perform the communication connection, the location data x calculated by the positioning module 30 at this time is the current location of the wireless mobile device 10, and the next wireless communication. When the module 20 and the base station 100 are normally connected again, the transmission unit 201 transmits the location data x to the communication network. The method of transmitting the location data x by the transmitting unit 201 may be transmitted by means of a general short message through a communication protocol, or may be transmitted through a non-structured supplementary service data (USSD) in a second generation global mobile communication protocol. x, but its transfer method is not limited. The content and establishment manner of the search suggestion table Table 1 will be specifically described below.

FIG. 2a is a schematic diagram of a search suggestion table Table 1 stored in the storage unit 40 of the wireless mobile device 10 of an embodiment. As shown in FIG. 2a, in this example, the field in the search suggestion table Table 1 of the present embodiment includes a plurality of regional location data A ₁ ~A _n , which represent different geographical locations where the wireless mobile device 10 may be located. The area location data A ₁ ~A _n can be marked in the search recommendation table Table 1 in a coordinate manner, for example, in units of latitude and longitude. For example, the data recorded in the regional location data A ₁ is (E 121∘37', N25∘09'), which means that the east longitude is 121∘37' and the north latitude is 25∘09'; then the actual geographical location is compared with this data. It is the second parking lot of Yangmingshan National Park. The search suggestion table Table 1 of this embodiment may further include a field labeling area range R ₁ ~R _n corresponding to each area location data A ₁ ~A _n , and the representative is centered on the area location data, and the area is The data is the range covered by the radius. From the previous embodiments, e.g., FIG. 2a searches the list of recommended area location data of Table 1 A ₁ corresponds to the data for the area range of 20 meters, as shown in FIG 2B, the location information indicates an area A ₁ (E121∘37 ', N25∘09 ') as the center of the radius of the circular area within the range of 20 meters belong to the scope of _a field corresponding to this location data area a.

The location location data and related data in Table 1 of the search suggestion table may be provided by different sources. In one example, the regional location data A ₁ -A _n are provided by the communication network; for example, the service provider of the communication network presets the search according to the area where the base station cannot be set up or the area of the weaker reception area. It is suggested that certain regional location data and regional scope data in the table are used by the wireless mobile device of the present invention. In another example, the regional location data A ₁ ~A _n is the location data x provided by the wireless mobile device. In fact, in this example, the communication network end receives and stores the location data from different wireless mobile devices as a source of information for the search suggestion list. In another embodiment, the regional location data A ₁ -A _n includes the information provided by the communication network and the information provided by the wireless mobile device. Specifically, the regional location data A ₁ ~A _n is defined as the location and scope of each area where the communication network cannot provide network services (whether provided by the communication network or provided by the wireless mobile device).

Referring to FIG. 2a, another field corresponding to each area location data A ₁ ~A _n in the search suggestion table Table 1 is the recommended search time T ₁ ~T _n , which represents the location of the wireless mobile device 10 in the area. The wireless communication module 20 is suggested to use the time interval for searching the communication network. To the above example, the area A ₁ corresponds to the location data suggest search time T _1, for example, 10 minutes, meaning it represents when wireless communication module 20 is located in the Yangmingshan National Park, the second parking lot, wireless communication module 20 is recommended every 10 Minutes to search for the communication network. That is, the wireless mobile device 10 of the present embodiment is located within the area radius data within a range of 20 meters from the regional location data A ₁ (E 121∘37', N25∘09'). Within the circular area, it is recommended to search the Internet every 10 minutes.

It can be seen from the above that the location location data included in the search suggestion table Table 1 is defined as the location and range of each area where the communication network cannot provide the network service, and therefore, when the wireless communication module 20 cannot perform the normal communication function ( For example, if the signal is not received, the network search time of the wireless mobile device 10 provided by the present invention will be lengthened to save power. Therefore, the length of the recommended search time T ₁ ~T _n corresponding to the regional location data A ₁ ~A _n in this embodiment is greater than the network search used by the wireless communication module 20 for normal normal communication functions. The length of time interval. For example, the normal search time of a communication network if the wireless communication module 20 is generally normal to the link to search every six minutes, then, for example, when the wireless mobile device 10 enters the search suggestions in the table Table A _p-area location data of 1 when the regional level, using wireless communication module 20 corresponding to the recommended search time T _p, which means, the wireless communication module 20 searching for a communication network will from time to time adjusted every 6 minutes every 12 minutes for search. The setting of the recommended search time T ₁ ~T _n corresponding to the location data of each area is generally established in the search recommendation table after the communication network is statistically and/or calculated. However, other The setting method and calculation standard can also be used without limiting the scope of the present invention.

Further, the wireless mobile device 10 according to the embodiment of the present invention sets the wireless communication module 20 to search for the communication network according to the location data x calculated by the positioning module 30 and the data of the suggested search table Table 1 stored by the storage unit 40. time. The wireless mobile device 10 compares the location data x with the regional location data A ₁ ~A _n , and determines whether the geographical location of the wireless mobile device 10 is located in the geographic location represented by any regional location data in the suggested search table Table 1 . If the wireless mobile device 10 is located in the regional location data A ₁ -A _n included in the suggestion search table Table 1, the wireless communication module 20 sets the time interval for searching the communication network to the recommended search time corresponding to the location of the region. And periodically search for communication networks at this interval.

Each area location data of the search suggestion table Table 1 has a corresponding weight value W ₁ ~W _n . The weight value W ₁ ~W _n corresponding to each area location data represents the importance and usage priority of the location data of the pen area compared to all other location data in the search suggestion table Table 1. When the range of the area corresponding to each area location data overlaps, the wireless mobile device 10 determines the area location data to be used according to the weight value. In addition, if any of the location location data in the search suggestion table has a weight value lower than a certain preset standard, the data will be ignored. In different embodiments, the weight value W may be determined by different parameters. For example, in the search suggestion table Table 1 shown in FIG. 2a, the weight value of each area location data is determined in the order of the establishment time of the pen area location data. In this case, the earlier the setup time, the older the location data representing the pen area, so the corresponding weight value is lower. In Table 1 of the search suggestion table, each area location data has a corresponding field to record the time when the location data of the area is created (or updated); for example, the area location data A ₁ as shown in FIG. 2a The establishment time is April 2, 2008, and the establishment time of the regional location data _Ap is March 11, 2008. Since the weight of the data that is established earlier is lower, the two data in this embodiment are The corresponding weight values are W ₁ =0.5 and W _p =0.3, respectively.

In other embodiments, the weight value of each area location data may be set according to other parameters. For example, the weight value of the area location data may be set according to the corresponding number of establishments in the location location data of the search suggestion table. The number of establishments means the number of times the communication network repeatedly receives the same location data from different sources. For example, if two different wireless mobile devices transmit the same location data to the communication network, the number of times the location data is established by the communication network is 2. The number of corresponding establishment times of different pen area location data can be used as a parameter of the weight value of the area location data. In general, the less the number of times a certain area location data is established, the less the number of times the wireless mobile device enters the area, so the weight value corresponding to the location data of the pen area is lower. As described above, the search suggestion list of the present invention is continuously updated (whether via the communication network or via the wireless mobile device), and therefore, the weight value corresponding to each data may be changed due to the update of other data. . In addition, the system setting or other parameters set by the user may be applied to the setting weight value, and is not limited to the setting modes of the above two embodiments.

Next, step 1021 is performed to determine or compare whether the current location data is located in any location location data in the search suggestion table. If YES in step 1021, then proceed to step 1023, otherwise return to step 1005 to re-check whether the connection with the communication network is successful. In step 1021, the area location data corresponding to the location data is found, and then step 1023 is performed to further It is determined whether the weight value corresponding to the position data of the pen area is higher than a preset standard. If the determination result is higher than the preset criterion, step 1025 is performed to search for the communication network by using the suggested search time corresponding to the location data of the pen area. If the weight value does not reach the preset standard, it indicates that the location data of the pen area is not suitable. Standard, so proceed to step 1027. Step 1027 ignores the pen area location data and returns to step 1005.

FIG. 3b is a flow chart of another embodiment of a method for setting a communication network search time. In detail, the figure is shown as a flow chart when the connection between the wireless mobile device and the communication network fails. First, similar to the foregoing embodiment, step 1005 checks whether the wireless communication module of the wireless mobile device and the communication network are successfully connected. If not, proceed to step 1020. Similarly, in step 1020, the location data of the wireless mobile device is calculated and stored. Next, step 1021 is performed to determine or compare whether the current location data is located in any location location data in the search suggestion table. If YES in step 1021, proceed to step 1022, otherwise proceed to step 1024. Step 1022 is to determine whether the location data is located in the area of the location data of two or more regions. If yes, proceed to step 1024 to compare the weight values of the location data of the plurality of regions where the location data is located, and then in step 1026, the comparison step The area location data with a higher weight value in 1024 is used, and the search communication network is searched according to the recommended search time corresponding to the area location data. If the determination in step 1022 is negative, it indicates that the location data only falls on the single region location data; then step 1023 is performed to determine whether the weight value corresponding to the location data of the pen region is higher than a preset criterion, and then according to FIG. 3a. The process takes additional steps.
