The portable terminal that the embodiment of the invention has a FM receiver receives the radio data system RDS signal in the fm broadcast signal, demodulates the RDS data message; Described portable terminal is determined the specific operation that it is corresponding according to described RDS data message; Described portable terminal is carried out described specific operation.By reading RDS information, carry out the pairing operation of described RDS information, make portable terminal can in the subregion, realize specific function or specific operation, can accurately locate portable terminal simultaneously, and only need install the FM receiver in portable terminal additional gets final product, do not need to arrange net in addition, be convenient to realize, can use on a large scale.
Referring to Fig. 1, communication system comprises portable terminal 101 and FM transmitter 102 in the embodiment of the invention.
Portable terminal 101 is used to receive the radio data system RDS signal that network side sends, and demodulates the RDS data message, determines the specific operation that it is corresponding according to described RDS data message, and carries out described specific operation.Preferable, in portable terminal 101 inside built-in aerial can be arranged in the embodiment of the invention.General portable terminal 101 be with earphone as antenna, but can not guarantee that the user uses earphone always, and can't receive FM (frequency modulation(FM)) signal when not having antenna, also just can't receive the RDS signal.Therefore the embodiment of the invention can adopt built-in aerial in portable terminal 101, can guarantee that the user when using the RDS function, needn't be subjected to the restriction of antenna.Portable terminal 101 is positioned at user side.
FM transmitter 102 is used for the transmitting RDS signal.Described FM transmitter 102 can be a powerful radio station, also can be a small-sized emitter.A network system can be a core with this FM transmitter 102.Need have the RDS signal in the FM signal that FM transmitter 102 sends.Wherein, according to the consensus standard of RDS signal, the RDS signal can have polytype, for example program column number, slow identity code, RTA Radio Text, internal application, emergency warning system etc.RDS signal in the embodiment of the invention can be selected this type of internal application.Because if select other types for use, may be received and demodulation by other FM equipment, thereby may cause other FM receiving equipments to produce wrong operation.FM transmitter 102 can send the RDS signal of same set form always incessantly, when portable terminal 101 enters into the coverage of FM transmitter 102, just can receive the RDS signal that FM transmitter 102 sends.When the power of FM transmitter 102 hour, its coverage may be also less, then can carry out the mode that honeycomb fashion covers by making a plurality of FM transmitters 102, enlarges its coverage.When FM transmitter 102 carries out the honeycomb fashion covering,, can make adjacent FM transmitter 102 be operated in different frequencies for avoiding interfering with each other of adjacent FM transmitter 102.For portable terminal 101, just need the RDS signal of at least two frequencies of search like this.For example, portable terminal 101 can switch to another frequency again and searches for after having searched for the RDS signal of a frequency.
Referring to Fig. 2 A, portable terminal 101 comprises FM receiver 1011, searches module 1012 and Executive Module 1013 in the embodiment of the invention.Described portable terminal 101 also comprises read module 1014 and memory module 1015.Wherein, read module 1014, search the processor that module 1012 and Executive Module 1013 can be arranged in described portable terminal 101.Memory module 1015 can be arranged in the processor of described portable terminal 101, also can be positioned at outside the processor of described portable terminal 101.Concrete, described portable terminal 101 can be a mobile phone.Fig. 2 B is depicted as the schematic diagram of communication system in the embodiment of the invention.
FM receiver 1011 is used to receive the RDS signal that network side sends, and it is demodulated the RDS data message.Concrete, described FM receiver 1011 can be a FM receiver chip.FM receiver 1011 can receive the RDS signal that network side sends by the built-in aerial of portable terminal 101.Can be by setting, FM receiver 1011 is opened automatically when making portable terminal 101 starts, and perhaps FM receiver 1011 also can be opened after being triggered.After FM receiver 1011 is opened, processor in the portable terminal can carry out initialization to it, all kinds of parameters of FM receiver 1011 are set, for example FM receiver 1011 are carried out the setting of init state setting, FM receive frequency, and dispose RDS operating state etc. for it.After FM receiver 1011 was opened, if it is in the coverage of certain FM transmitter 102, when these FM transmitter 102 transmitting RDS signals, FM receiver 1011 can receive.After FM receiver 1011 receives the RDS signal, it is carried out demodulation, obtain the RDS data message, FM receiver 1011 notice read modules 1014 read afterwards, wherein Tong Zhi mode can be to interrupt, and after promptly FM receiver 1011 demodulates the RDS data message, produces an interruption, have no progeny during read module 1014 receives, read the RDS data message of storage in the FM receiver 1011.Wherein, read module 1014 can read the RDS data message of storage in the FM receiver 1011 by data wire, for example can pass through I 2Modes such as C (Inter-Integrated Circuit, twin wire universal serial bus) bus, SPI (Serial Peripheral Interface (SPI)) bus read.
If FM receiver 1011 is in mode of operation always, then the standby current of portable terminal 101 can be than higher, causes depending on the stand-by time that battery carries out the portable terminal 101 of work and significantly shorten.Preferable, can make FM receiver 1011 intermittent unlatchings, be that FM receiver 1011 needn't be opened all the time, periodically the short time opens, for example, FM receiver 1011 can be opened once by per minute, and each opening time continues 1 second, portable terminal 101 standby currents are 20mA when supposing 1011 unlatchings of FM receiver, and then the added value of portable terminal 101 standby currents is:
(20mA*1s)/60s＝0.33mA (1)
The electric current that increases is less, and is less to the influence of portable terminal 101 standby times.Portable terminal 101 that standby current is 4mA for example, when it is inner increase FM receiver 1011 after, standby current also only is 4.33mA when FM receiver 1011 is opened, if the battery capacity of this portable terminal 101 is 1000mAh, then former standby time is:
1000mAh/4mA＝250h (2)
Increasing FM receiver 1011 back standby times is:
1000mAh/4.33mA＝230h (3)
It is not too big increasing by the 1011 back standby time influences to portable terminal 101 of FM receiver as can be seen.
Perhaps can set FM receiver 1011 opened in the set time.For example, the FM transmitter is only at 8:30-9:30 transmitting RDS signal in the morning, then can FM receiver 1011 be opened in this period by setting, closing in the section At All Other Times, because the operating current of FM receiver 1011 is less, opening time is also shorter, therefore can reduce the standby current of portable terminal 101, avoids significantly shortening the standby time of portable terminal 101 as far as possible.
Searching module 1012 is used for determining the specific operation that it is corresponding according to described RDS data message.In portable terminal 101 inside an information table can be arranged, store each RDS data message, concrete operations corresponding with every kind of RDS data message and the corresponding relation between them in this information table, this information table can be stored in the memory module 1015.After read module 1014 reads the RDS data message, search module 1012 and can in this information table, inquire about the concrete specific operation corresponding with this RDS data message.In information table, do not inquire this RDS data message if search module 1012, or do not inquire the concrete operations of this RDS data message correspondence, think that then this RDS data message is wrong or be subjected to interference, can notify Executive Module 1013 to abandon this RDS data message.When portable terminal 101 was in the covering radius of FM transmitter 102 always, because of FM transmitter 102 may constantly send identical information, then FM receiver 1011 also will constantly receive identical RDS data message.For example can set searching module 1012 in advance, if make its read module 1014 in the Preset Time scope read identical RDS data message then can only carry out initial once-through operation.Concrete, search a timer T2 can be arranged in the module 1012, can be the default duration of T2, for example this duration is one hour, in one hour, receive identical RDS data message if then search module 1012, can promptly only send message to Executive Module 103 at first only in the once-through operation of carrying out at first, notice Executive Module 103 is carried out the pairing specific operation of this RDS data message.Search the specific operation that RDS data message that module 1012 reads according to read module 1014 for the first time inquires this RDS data message correspondence, to Executive Module 1013 transmission information, notice Executive Module 1013 is carried out described specific operation, and opening timing device T2; When the RDS data message that reads according to read module 1014 once more when enquiry module 1012 inquires the operation of this RDS data message correspondence, if determine that this specific operation is identical with the specific operation that inquired last time, whether the duration of then judging T2 arrives, if the T2 duration does not arrive, then can not operate, if the T2 duration arrives, then can continue to Executive Module 1013 transmission information, notice Executive Module 1013 is carried out described specific operation.Perhaps also can adopt other method to avoid repetitive operation constantly, save resource, prevent misoperation.Can be set to the revisable pattern of user by T2, the user can by with directly the making amendment alternately of portable terminal, perhaps also can revise by alternate manner, for example can by with portable terminal with make amendment after computer links to each other.So just needn't all need could realize the adjustment of function by software is upgraded, it is more convenient to use at every turn.
Executive Module 1013 is used to carry out described specific operation.After searching module 1012 inquires RDS data message correspondence from information table concrete specific operation, Executive Module 1013 is carried out described specific operation.For example, search module 1012 inquires RDS data message correspondence from information table concrete specific operation and be " all incoming calls of rejection ", then Executive Module 1013 is by carrying out relative set, all incoming calls of rejection to portable terminal 101.
Read module 1014 is used to read the RDS data message.After FM receiver 1011 received the RDS data message, read module 1014 read described RDS data message from FM receiver 1011.Wherein, can there be buffer memory FM receiver 1011 inside, FM receiver 1011 can be with the RDS data information memory that receives within it in the buffer memory of portion, read module 1014 can receive FM receiver 1011 in have no progeny and from the buffer memory of FM receiver 1011 inside, read the RDS data message.Wherein, the mode of reading can preestablish as required, for example, read module 1014 is carried out twice or the reading of more times number (when read module 1014 read finish after RDS signal in the FM receiver 1011 still exist, can after receiving the RDS signal once more, cover the RDS signal that this time receives automatically), whether repeatedly read the RDS signal that can judge reception wrong.If make read module 1014 carry out reading for twice by setting, the RDS signal that at every turn reads can be a packet, then read module 1014 can compare the packet that reads for twice, if the packet that reads for twice is identical, then the RDS signal of proof reception is correct, can carry out subsequent operation, if the packet that reads for twice is inequality, the RDS signal that then shows reception is wrong, and read module 1014 can abandon it.
The intensity of FM signal can be along with dying down away from FM transmitter 102 gradually, and the error rate of RDS also can rise gradually.For making system can carry out work accurately and effectively, read module 1014 is before reading the RDS data message from FM receiver 1011, can at first read RSSI (the Received Signal Strength Indication in the FM receiver 1011, the indication of received signal intensity) value, this RSSI value can be stored in the internal register of FM receiver 1011.Read module 1014 can be regularly to read, and also can be to read after being triggered, and for example a kind of trigger event can be that FM receiver 1011 is opened.When being determined current FM signal strength signal intensity and being, read module 1014 can enter the state of waiting for that FM receiver 1011 interrupts, the state of RDS data message to be read such as promptly enters.When the interruption of FM receiver 1011 arrived, read module 1014 read the RDS data message in the FM receiver 1011.A timer T1 can be arranged in the read module 1014, can when FM receiver 1011 begins to enter the state of waiting for interruption, can open this timer T1 in advance for T1 sets a duration, arrive yet if in the duration of T1, interrupt, then can stop to wait for, carry out other operation.The duration of T1 can be called the first default duration.If in the T1 duration, interrupt arriving, show that then FM receiver 1011 has received the RDS signal, then read module 1014 reads.For making whole system more flexible, can be set to the revisable pattern of user by T1, the user can by with directly the making amendment alternately of portable terminal, perhaps also can revise by alternate manner, for example can by with portable terminal with make amendment after computer links to each other.So just needn't all need could realize the adjustment of function by software is upgraded, it is more convenient to use at every turn.
Memory module 1015 is used for information table memory.Each RDS data message, the concrete specific operation corresponding and the corresponding relation between them have been stored in this information table with every kind of RDS data message.After read module 1014 reads the RDS data message, search module 1012 and can in this information table, inquire about the concrete specific operation corresponding with this RDS data message.Can be set to the revisable pattern of user by this information table, the user can by with directly the making amendment alternately of portable terminal, perhaps also can revise by alternate manner, for example can by with portable terminal with make amendment after computer links to each other.So just needn't all need could realize the adjustment of function by software is upgraded, it is more convenient to use at every turn.
Referring to Fig. 3, portable terminal described in the embodiment of the invention 101 can also comprise determination module 1016.Described determination module 1016 can be arranged in the processor of described portable terminal 101.
Determination module 1016 is used for determining the intensity of FM signal.After the RSSI value in read module 1014 reads FM receiver 1011, determination module 1016 is determined the intensity of FM signal according to this RSSI value.Read module 1014 can read the RSSI value in the FM receiver 1011 when FM receiver 1011 is opened.Can preserve pre-set threshold value in the determination module 1016, determination module 1016 compares RSSI value and this threshold value that read module 1014 reads, if this RSSI value does not satisfy pre-set threshold, for example the RSSI value is less than this threshold value, represent that then 1011 search of FM receiver are less than the FM signal, or the FM signal is very faint, then determination module 1016 determines that the FM signal strength signal intensity is for poor, this moment, determination module 1016 can be closed FM receiver 1011, so, if this moment portable terminal 101 be not in the coverage of FM transmitter 102 or be in its coverage edge but signal a little less than, then close the misoperation that FM receiver 1011 can avoid portable terminal 101 to occur, and the duration that FM receiver 1011 is opened is shorter, more effectively reduces the standby current of portable terminal 101.If this RSSI value satisfies pre-set threshold, for example the RSSI value is not less than this threshold value, then determination module 1016 determines that the FM signal strength signal intensities are for well, then notify read module 1014 to wait for the state that FM receiver 1011 interrupts, read the RDS data message in the FM receiver 1011 when arriving with the interruption of convenient FM receiver 1011.If read module 1014 is not waited until the interruption of FM receiver 1011 in the duration of timer T1, then can notify determination module 1016 to close FM receiver 1011.Wherein, determination module 1016 can send close message by control line FM receiver 1011, and FM receiver 1011 is carried out shutoff operation after receiving described close message.The FM signal strength signal intensity meets the demands, but FM receiver 1011 does not interrupt producing, portable terminal 101 may be in FM transmitter 102 coverages or the edge of FM transmitter 102 coverages, but may can't receive because a variety of causes causes the FM poor TV signal clear.Wherein, the operation of closing FM receiver 1011 can be to make FM receiver 1011 enter off-mode by control line.A timer T3 can be arranged in determination module 1016, when determination module 1016 is closed FM receiver 1011, open this timer T3, can set a duration for T3 in advance as required, determination module 1016 is opened FM receiver 1011 once more when the duration of this T3 arrives, and so just can realize the intermittence of FM receiver 1011 is opened.The duration of T3 can be called the second default duration.Can be set to the revisable pattern of user by T3, the user can by with directly the making amendment alternately of portable terminal, perhaps also can revise by alternate manner, for example can by with portable terminal with make amendment after computer links to each other.So just needn't all need could realize the adjustment of function by software is upgraded, it is more convenient to use at every turn.Determination module 1016 can be arranged in the processor of portable terminal 101.
