Description

Method for performing specific operation of mobile terminal, mobile terminal and communication system The present application claims to be submitted to the Chinese Patent Office on May 19, 2011, and the application number is 201110130264.5, and the invention name is "a method for mobile terminal to perform a specific operation, moving Priority of Chinese Patent Application for Terminals and Communication Systems, the entire contents of which are incorporated herein by reference. Technical field

The present invention relates to the fields of communication, electronic and embedded, and in particular to a method, a mobile terminal and a communication system for a mobile terminal to perform a specific operation. Background technique

The Radio Data System (RDS) is the most widely used and fastest-growing method of data broadcasting in all multi-program broadcasting. Due to the timeliness of FM broadcasting and the particularity of broadcasting frequency resources, RDS has been widely accepted and adopted by many countries and regions in the world since its birth.

The FM band of the RDS receiver is in the range of 87.5 108.0 MHz, and the bands of adjacent stations are at least 100 kHz apart, and the subcarrier data is loaded at 57 kHz. Data content includes station type, program type, traffic announcements, advertising information, standard time, weather forecasts, and more. An open data interface is also provided to provide data text application channels for users with special requirements.

Generally, wireless handheld devices (such as mobile phones) should communicate with their base stations or wireless stations wirelessly. Therefore, this kind of equipment is not limited by geography and space. That is, the base station or the wireless station cannot accurately determine the location of the wireless handheld device (e.g., within 10 m around a certain point).

And if the phone can achieve all of its pre-set functions in a specific location, it will bring greater convenience to users. For example, you want to have your phone restrict certain features (such as rejecting all calls in a meeting room) or implement certain special features (such as sending a text message to a fixed number) within 10m of a location. This function can be implemented by the function of the base station. For example, the base station can send commands to mobile phones within its range, so that all phones entering the area reject all incoming calls. But this has a lot of limitations. First, the base station has a large radiation range, and may have a minimum of 2-3 kilometers of radiation. It is not conducive to precise positioning. Second, since the base station is fixed, the current base stations are basically arranged. It is not easy to think of a separate network for a certain area. As a result, it is possible to achieve a free configuration of the area. Summary of the invention

In the embodiment of the present invention, the mobile terminal having the FM receiver receives the RDS signal in the FM broadcast signal, and demodulates the RDS data information; the mobile terminal determines the corresponding specific operation according to the RDS data information; Perform the specific operation. By reading the RDS data information, performing operations corresponding to the RDS data information, so that the mobile terminal can implement a specific function or a specific operation in a part of the area, and can perform fine on the mobile terminal. The bit is determined, and only the FM receiver needs to be installed in the mobile terminal, and no additional network is needed, which is convenient to implement and can be widely used.

Referring to Fig. 1, a communication system in the embodiment of the present invention includes a mobile terminal 101 and an FM transmitter 102.

The mobile terminal 101 is configured to receive an RDS signal transmitted by the network side, demodulate the RDS data information, determine a corresponding specific operation according to the RDS data information, and perform the specific operation. Preferably, in the embodiment of the present invention, there may be a built-in antenna inside the mobile terminal 101. Generally, the mobile terminal 101 uses an earphone as an antenna, but cannot guarantee that the user always uses the earphone, and cannot receive the FM signal when there is no antenna, and cannot receive the RDS signal. Therefore, the embodiment of the present invention can use the built-in antenna in the mobile terminal 101, and can ensure that the user does not need to be limited by the antenna when using the RDS function. The mobile terminal 101 is located on the user side.

The FM transmitter 102 is used to transmit an RDS signal. The FM transmitter 102 can be a high power station or a small transmitter. A network system can be centered on the FM transmitter 102. The FM signal transmitted by the FM transmitter 102 is required to carry an RDS signal. Among them, according to the protocol standard of the RDS signal, the RDS signal can be of various types, such as a program column number, a slow flag code, a broadcast text, an internal application, an emergency alarm system, and the like. The RDS signal in the embodiment of the present invention can select this type of internal application. Because other types may be received and demodulated by other FM devices, other FM receiving devices may cause erroneous operations. The FM transmitter 102 can continuously transmit the same fixed format RDS signal, and when the mobile terminal 101 enters the coverage of the FM transmitter 102, it can receive the RDS signal transmitted by the FM transmitter 102. When the power of the FM transmitter 102 is small, its coverage may also be small, and its coverage can be expanded by making the plurality of FM transmitters 102 cellularly covered. In the case of cellular coverage by the FM transmitter 102, adjacent FM transmitters 102 can be operated at different frequencies to avoid mutual interference with adjacent FM transmitters 102. Thus, for the mobile terminal 101, it is necessary to search for RDS signals of at least two frequencies. For example, the mobile terminal 101 can switch to another frequency for searching after searching for the RDS signal of one frequency.

Referring to FIG. 2A, the mobile terminal 101 in the embodiment of the present invention includes an FM receiver 1011, a lookup module 1012, and an execution module 1013. The mobile terminal 101 further includes a reading module 1014 and a storage module 1015. The reading module 1014, the searching module 1012, and the executing module 1013 may all be located in the processor of the mobile terminal 101. The storage module 1015 may be located in the processor of the mobile terminal 101 or may be located outside of the processor of the mobile terminal 101. Specifically, the mobile terminal 101 can be a mobile phone. 2B is a schematic diagram of a communication system in accordance with an embodiment of the present invention.

The FM receiver 1011 is configured to receive an RDS signal transmitted by the network side, and demodulate the RDS data information from the RDS signal. Specifically, the FM receiver 1011 can be an FM receiver chip. The FM receiver 1011 can receive the RDS signal transmitted by the network side through the built-in antenna of the mobile terminal 101. The FM receiver 1011 can be automatically turned on when the mobile terminal 101 is powered on by setting, or the FM receiver 1011 can be turned on after being triggered. After the FM receiver 1011 is turned on, the processor in the mobile terminal can initialize it and set the FM receiver. Various parameters of 1011, such as setting the initialization state of the FM receiver 1011, setting the FM receiving frequency, and configuring the RDS working state for it. After the FM receiver 1011 is turned on, if it is within the coverage of an FM transmitter 102, the FM receiver 1011 can receive when the FM transmitter 102 transmits the RDS signal. After receiving the RDS signal, the FM receiver 1011 demodulates the RDS data to obtain the RDS data information, and then the FM receiver 1011 notifies the reading module 1014 to perform the reading, wherein the notification may be interrupted, that is, the FM receiver 1011 demodulates. After the RDS data information is output, an interrupt is generated, and after receiving the interrupt, the reading module 1014 reads the RDS data information stored in the FM receiver 1011. The reading module 1014 can read the RDS data information stored in the FM receiver 1011 through a data line, for example, through an Inter-Integrated Circuit (I2C) bus and a Serial Peripheral Interface (SPI). Read by bus or the like.

If the FM receiver 1011 is in the active mode, the standby current of the mobile terminal 101 will be relatively high, resulting in a significantly shorter standby time of the mobile terminal 101 that depends on the battery to operate. Preferably, the FM receiver 1011 can be intermittently turned on, that is, the FM receiver 1011 does not have to be always on, and can be turned on periodically for a short time. For example, the FM receiver 1011 can be turned on once every minute, and the on time is 1 second each time. Assuming that the standby current of the mobile terminal 101 when the FM receiver 1011 is turned on is 20 mA, the increase value of the standby current of the mobile terminal 101 is:

( 20 mA*ls ) /60s=0.33 mA ( 1 )

The increased current is small, which has less influence on the standby time of the mobile terminal 101. For example, a mobile terminal 101 with a standby current of 4 mA, when the FM receiver 1011 is internally added, the standby current is only 4.33 mA when the FM receiver 1011 is turned on, and if the battery capacity of the mobile terminal 101 is 1000 mAh, the original standby Duration is:

1000 mAh/4 mA=250h ( 2 )

Increase the standby time after the FM receiver 1011 is:

1000 mAh/4.33 mA=230h ( 3 )

It can be seen that the influence on the standby duration of the mobile terminal 101 after the addition of the FM receiver 1011 is not too large.

Alternatively, the FM receiver 1011 can be set to be turned on for a fixed time. For example, if the FM transmitter transmits the RDS signal only at 8:30-9:30 am, the FM receiver 1011 can be turned on only during this period and turned off during other periods, due to the operating current of the FM receiver 1011. The smaller, the turn-on time is also shorter, so that the standby current of the mobile terminal 101 can be reduced, and the standby time of the mobile terminal 101 can be drastically shortened as much as possible.

The lookup module 1012 is configured to determine a corresponding specific operation according to the RDS data information. Inside the mobile terminal 101, there may be an information table in which each RDS data information, a specific operation corresponding to each RDS data information, and a correspondence between RDS data information and a specific operation are stored, and the information table may be stored. In the storage module 1015. After the reading module 1014 reads the RDS data information, the lookup module 1012 can query the information table for a specific operation corresponding to the RDS data information. If the lookup module 1012 queries the specific operation corresponding to the RDS data information in the information table, the notification execution module 103 performs the specific operation that is queried. If the search module 1012 does not query the RDS data information in the information table, or does not query the specific operation corresponding to the RDS data information, If the RDS data information is considered to be incorrect or has been disturbed, the execution module 1013 may be notified to discard the RDS data information. When the mobile terminal 101 is directly in the coverage radius of the FM transmitter 102, since the FM transmitter 102 may continuously transmit the same information, the FM receiver 1011 will continuously receive the same RDS data information. To this end, the lookup module 1012 can be pre-set so that it can perform only the first operation if the read module 1014 reads the same RDS data information within a preset time range. Specifically, the search module 1012 may have a timer T2, and may preset a duration for the T2. For example, if the duration is one hour, the search module 1012 may only perform the initial RDS data information within one hour. One operation, that is, only initially sends a message to the execution module 103, informing the execution module 103 to perform the specific operation corresponding to the RDS data information. The search module 1012 first queries the specific operation corresponding to the RDS data information according to the RDS data information read by the reading module 1014, sends information to the execution module 1013, notifies the execution module 1013 to perform the specific operation, and starts the timer T2. When the query module 1012 further queries the specific operation corresponding to the RDS data information according to the RDS data information read by the reading module 1014, if it is determined that the specific operation is the same as the specific operation that was last queried, it is determined whether the duration of T2 is If the T2 duration has not arrived, no operation may be performed. If the T2 duration has expired, the information may continue to be sent to the execution module 1013, and the execution module 1013 is notified to perform the specific operation. Or you can use other methods to avoid repeated operations to save resources and prevent misuse. The T2 can be set to a user-modifiable mode, and the user can directly modify the interaction with the mobile terminal, or can be modified by other means, for example, by connecting the mobile terminal to the computer and then modifying it. In this way, it is not necessary to upgrade the software every time to realize the function adjustment, and the use is more convenient.

Execution module 1013 is for performing the specific operation. When the lookup module 1012 queries the specific operation corresponding to the RDS data information from the information table, the execution module 1013 performs the specific operation. For example, if the specific operation corresponding to the RDS data information is queried from the information table to the "reject all incoming calls", the execution module 1013 rejects all incoming calls by setting the mobile terminal 101 accordingly.

The reading module 1014 is configured to read RDS data information. After the FM receiver 1011 demodulates the RDS data information, the reading module 1014 reads the RDS data information from the FM receiver 1011. The FM receiver 1011 may have a buffer inside, and the FM receiver 1011 may store the demodulated RDS data information in its internal buffer. The reading module 1014 may receive the FM receiver 1011 from the FM after receiving the interruption of the FM receiver 1011. The RDS data information is read in the buffer inside the machine 1011. The reading mode can be preset according to requirements. For example, the reading module 1014 can be read twice or more times (the RDS signal in the FM receiver 1011 still exists after the reading module 1014 reads the reading). It can automatically cover the received RDS signal after receiving the RDS signal again. The multiple reading can determine whether the received RDS signal is incorrect. If the read module 1014 performs two readings by setting, the RDS data information read each time may be one data packet, the reading module 1014 may compare the data packets read twice, if the data is read twice. If the received data packets are the same, it is proved that the received RDS signal is correct, and subsequent operations can be performed. If the data packets read twice are different, it indicates that the received RDS signal is incorrect, and the reading module 1014 can discard it. The intensity of the FM signal will gradually weaken as it moves away from the FM transmitter 102, and the bit error rate of the RDS signal will gradually increase. In order for the system to work accurately and efficiently, the reading module 1014 may first read the Received Signal Strength Indication (RSI) in the FM receiver 1011 before reading the RDS data information from the FM receiver 1011. The RSSI value can be stored in the internal register of the FM receiver 1011. The reading module 1014 may be a timed read or may be read after being triggered. For example, a trigger event may be that the FM receiver 1011 is turned on. When it is determined that the current FM signal strength is good, the reading module 1014 may enter a state of waiting for the FM receiver 1011 to be interrupted, that is, enter a state of waiting to read the RDS data information. When the interruption of the FM receiver 1011 comes, the reading module 1014 reads the RDS data information in the FM receiver 1011. There may be a timer T1 in the reading module 1014, and a time length may be set for T1 in advance, and the timer T1 may be turned on when the reading module 1014 starts to enter the state of waiting for an interrupt, if the interrupt is not interrupted within the duration of T1. When you arrive, you can stop waiting and perform other operations. The duration of T1 can be referred to as the first preset duration. If the interruption occurs within the T1 duration, it indicates that the FM receiver 1011 has received the RDS signal, and the reading module 1014 performs the reading. In order to make the whole system more flexible, T1 can be set to a user-modifiable mode, which can be directly modified by the user through interaction with the mobile terminal, or can be modified by other means, for example, by connecting the mobile terminal to the computer. modify. In this way, it is not necessary to upgrade the software every time to realize the function adjustment, and the use is more convenient.

The storage module 1015 is configured to store an information table. The information table stores respective RDS data information, specific operations corresponding to each RDS data information, and correspondence between RDS data information and specific operations. After the reading module 1014 reads the RDS data information, the lookup module 1012 can query the information table for a specific operation corresponding to the RDS data information. The information table can be set to a user-modifiable mode, and the user can directly modify it by interacting with the mobile terminal, or can be modified by other means, for example, by connecting the mobile terminal to a computer and then modifying it. In this way, it is not necessary to upgrade the software every time to realize the function adjustment, and the use is more convenient.

Referring to FIG. 3, the mobile terminal 101 in the embodiment of the present invention may further include a determining module 1016. The determination module 1016 can be located in a processor of the mobile terminal 101.

The determination module 1016 is operative to determine the strength of the FM signal. After the reading module 1014 reads the RSSI value in the FM receiver 1011, the determining module 1016 determines the strength of the FM signal based on the RSSI value. The read module 1014 can read the RSSI value in the FM receiver 1011 when the FM receiver 1011 is turned on. The determining module 1016 may store a preset threshold, and the determining module 1016 compares the RSSI value read by the reading module 1014 with the threshold. If the RSSI value does not meet a preset threshold, for example, the RSSI value is less than the threshold. The threshold value indicates that the FM receiver 1011 cannot find the FM signal, or the FM signal is very weak, and the determining module 1016 determines that the FM signal strength is poor. At this time, the determining module 1016 can turn off the FM receiver 1011, so that if If the mobile terminal 101 is not within the coverage of the FM transmitter 102 or at the edge of its coverage but the signal is weak, then turning off the FM receiver 1011 can avoid erroneous operations that may occur in the mobile terminal 101, and also cause the FM receiver 1011 to be turned on. The duration is shorter, and the standby current of the mobile terminal 101 is more effectively reduced. If the RSSI value satisfies a preset threshold, for example, the RSSI value is not If the threshold is greater than the threshold, the determining module 1016 determines that the FM signal strength is good, and notifies the reading module 1014 to enter a state of waiting for the FM receiver 1011 to be interrupted, so as to read the RDS in the FM receiver 1011 when the interruption of the FM receiver 1011 arrives. Data information. If the reading module 1014 does not wait for the interruption of the FM receiver 1011 within the duration of the timer T1, the determining module 1016 may be notified to turn off the FM receiver 1011. The determining module 1016 may send a close message to the FM receiver 1011 through the control line, and the FM receiver 1011 performs a close operation after receiving the close message. The FM signal strength meets the requirements, but the FM receiver 1011 is not interrupted. The mobile terminal 101 may be within the coverage of the FM transmitter 102 or the edge of the coverage of the FM transmitter 102, but the FM signal may be unclear for various reasons. Unable to receive. The operation of turning off the FM receiver 1011 may be to bring the FM receiver 1011 into a shutdown state through a control line. There may be a timer T3 in the determining module 1016. When the determining module 1016 turns off the FM receiver 1011, the timer T3 is turned on, and a time length may be set for T3 according to requirements. When the duration of the T3 comes, the determining module 1016 is determined. The FM receiver 1011 is turned on again, so that the intermittent opening of the FM receiver 1011 can be realized. The duration of T3 can be referred to as the second preset duration. The T3 can be set to a user-modifiable mode, and the user can directly modify the interaction with the mobile terminal, or can be modified by other means, for example, by connecting the mobile terminal to the computer and then modifying it. In this way, it is not necessary to upgrade the software every time to realize the function adjustment, and the use is more convenient. The determination module 1016 can be located in the processor of the mobile terminal 101.

The following describes the information processing method through a specific process.

Referring to FIG. 4, the main method for the mobile terminal to perform a specific operation in the embodiment of the present invention is as follows:

Step 401: The mobile terminal 101 having the FM receiver 1011 receives the RDS signal in the FM broadcast signal, and demodulates the RDS data information.

Step 402: The mobile terminal 101 determines a corresponding specific operation according to the RDS data information.

Step 403: The mobile terminal 101 performs the specific operation.

Referring to FIG. 5, the detailed method for the mobile terminal to perform a specific operation in the embodiment of the present invention is as follows:

Step 501: The reading module 1014 reads the RSSI value in the FM receiver 1011. The reading module 1014 can read the RSSI value in the FM receiver 1011 when the FM receiver 1011 is powered on.

Step 502: The determining module 1016 determines whether the RSSI value is less than a preset threshold. When the result of the determination is YES, proceed to step 503, otherwise proceed to step 504.

Step 503: The determining module 1016 turns off the FM receiver 1011. End the process.

Step 504: The reading module 1014 waits for an interruption of the FM receiver 1011.

Step 505: When the interrupt of the FM receiver 1011 arrives, the reading module 1014 reads the RDS data information in the FM receiver 1011. The reading module 1014 can read twice and determine whether the RDS data information read twice is the same. If they are the same, the subsequent operations are continued. If they are not the same, the RDS data information can be discarded.

Alternatively, if the interruption of the FM receiver 1011 does not arrive within the T1 duration, the determination module 1016 may be notified to turn off the FM receiver 1011. Step 506: The searching module 1012 queries and determines an operation corresponding to the RDS data information.

Step 507: The execution module 1013 performs the specific operation.

The mobile terminal 101 having the FM receiver 1011 in the embodiment of the present invention receives the RDS signal in the FM broadcast signal, and demodulates the RDS data information; the mobile terminal 101 determines a corresponding specific operation according to the RDS data information; The mobile terminal 101 performs the specific operation. By reading the RDS data information, the specific operation corresponding to the RDS data information is performed, so that the mobile terminal 101 can implement a specific function or a specific operation in a partial area, and at the same time, the mobile terminal 101 can be accurately positioned, and only needs to be moved. The FM receiver 1011 can be added to the terminal 101, and no additional network is needed, which is easy to implement and can be widely used. The FM receiver 1011 can be intermittently turned on or turned on within a preset time to reduce the influence of the FM receiver 1011 on the standby current of the mobile terminal 101, and the influence of the FM receiver 1011 on the standby duration of the mobile terminal can be minimized as much as possible. The mobile terminal 101 can use the built-in antenna to ensure that the user does not have to be limited by the antenna when using the RDS function. A threshold may be set in advance, and the RSSI value in the read FM receiver 1011 is compared with the threshold. When the RSSI value does not satisfy the threshold condition, the FM receiver 1011 is turned off to prevent the erroneous operation of the FM receiver 1011. When a low power FM transmitter 102 is used, multiple FM transmitters 102 can be used for cellular coverage to expand their coverage. When the RDS data information is read from the FM receiver 1011, it is possible to determine whether the RDS data information is correct by reading and comparing multiple times. It is also possible to avoid repeated operations many times by setting the RDS signals received by the FM receiver 1011 to be the same.
