In the embodiment of the invention, after the fixed station system acquires the broadcast information, the broadcast information can be respectively broadcast to the mobile stations through a plurality of fixed stations.

Among the plurality of fixed stations, the broadcast frequency is different for each fixed station.

For example, assume that a fixed station system includes 5 fixed stations, fixed station one, fixed station two, fixed station three, fixed station four, and fixed station five, respectively. The broadcast frequency of the first fixed station may be 9.23MHz, the broadcast frequency of the second fixed station may be 10.61MHz, the broadcast frequency of the third fixed station may be 5.88MHz, the broadcast frequency of the fourth fixed station may be 20.76MHz, and the broadcast frequency of the fifth fixed station may be 26.55MHz, so that the broadcast frequencies of each of the 5 fixed stations are different.

103. The mobile station acquires a plurality of broadcast information broadcast by a plurality of fixed stations.

In the embodiment of the invention, the mobile station can acquire the broadcast information from each fixed station, so that a plurality of broadcast information can be obtained, and each broadcast information corresponds to one fixed station.

It should be noted that, the broadcast information broadcast by each fixed station is the same, and the broadcast information received by the mobile station from each fixed station may be different due to the influence of ionospheric fluctuation, environmental noise, and the like.

It should be noted that, each fixed station is only provided with one broadcast frequency, and the mobile station may receive broadcast information broadcast by a plurality of frequencies, so that the mobile station may receive broadcast information broadcast by each fixed station.

104. The mobile station demodulates the plurality of broadcast information to obtain demodulated broadcast information.

In the embodiment of the invention, after the mobile station acquires a plurality of broadcast information, the mobile station needs to demodulate the plurality of broadcast information, so as to obtain demodulated broadcast information.

Demodulation is the process of recovering information from a modulated signal carrying the information. In various information transmission or processing systems, a transmitting end modulates a carrier wave with a message to be transmitted, thereby generating a signal carrying the message to be transmitted, and then sends the signal to a receiving end, which must demodulate the signal to obtain the transmitted message.

105. The mobile station processes the demodulated broadcast information to obtain target broadcast information.

In the embodiment of the present invention, the number of the demodulated broadcast information obtained by the mobile station may be one or more, so if the number of the demodulated broadcast information is one, the mobile station may determine the demodulated broadcast information as the target broadcast information; if the number of the demodulated broadcast information is plural, the mobile station may process the demodulated broadcast information to obtain target broadcast information.

Optionally, when the number of the demodulated broadcast information is plural, that is, the demodulated broadcast information includes the first broadcast information and the second broadcast information, the mobile station processes the demodulated broadcast information to obtain the target broadcast information, which may specifically include: the mobile station compares the first broadcast information with the second broadcast information, and under the condition that the repeated broadcast information exists in the first broadcast information and the second broadcast information, the mobile station combines the second broadcast information with the first broadcast information after deleting the repeated broadcast information to obtain target broadcast information; or the mobile station performs combination processing on the first broadcast information and the second broadcast information after deleting the repeated broadcast information to obtain target broadcast information; and under the condition that the first broadcast information and the second broadcast information are detected to have no repeated broadcast information, the mobile station performs combination processing on the first broadcast information and the second broadcast information to obtain target broadcast information.

In this alternative implementation, after the mobile station compares the first broadcast information and the second broadcast information, there may be two results, respectively: the first broadcast information and the second broadcast information have repeated broadcast information, and the first broadcast information and the second broadcast information do not have repeated broadcast information; then, in the case that the first broadcast information and the second broadcast information have repeated broadcast information, the mobile station may delete the repeated broadcast information to obtain target broadcast information; under the condition that the first broadcast information and the second broadcast information do not have repeated broadcast information, the mobile station can directly obtain target broadcast information according to the first broadcast information and the second broadcast information.

Illustratively, assume that the first broadcast information is "1, 2, 3, 4, 5, 7, 9, 15, 28", and the second broadcast information is "2, 3, 6, 10, 11, 12, 15, 18, 19, 29, 30". After the mobile station compares the first broadcast information and the second broadcast information, it can be seen that the first broadcast information and the second broadcast information have repeated broadcast information of '2, 3 and 15', so that the mobile station can delete the repeated broadcast information from the first broadcast information to obtain '1, 4, 5, 7, 9 and 28', and then combine the repeated broadcast information with the second broadcast information to obtain target broadcast information of '1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 15, 18, 19, 28, 29 and 30'; the mobile station may also delete the repeated broadcast information from the second broadcast information to obtain "6, 10, 11, 12, 18, 19, 29, 30", and then combine with the first broadcast information to obtain the target broadcast information "1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 15, 18, 19, 28, 29, 30".

Illustratively, assume that the first broadcast information is "1, 2, 3, 4, 5, 7, 9, 15, 28", and the second broadcast information is "6, 10, 11, 12, 18, 19, 29, 30". After the mobile station compares the first broadcast information and the second broadcast information, it can be seen that there is no repeated broadcast information in the first broadcast information and the second broadcast information, and then the mobile station can directly combine the first broadcast information and the second broadcast information to obtain target broadcast information "1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 15, 18, 19, 28, 29, 30".

Example two

As shown in fig. 2, an embodiment of the present invention provides a broadcast information processing method, which may further include the steps of:

201. The fixed station system acquires the broadcast information.

202. The fixed station system splits the broadcast information into a plurality of sub-broadcast information and marks each sub-broadcast information with a packet sequence number.

In the embodiment of the present invention, after the fixed station system acquires the broadcast information, the size of the broadcast information may be detected, if the size of the broadcast information is greater than the preset payload size, it may be indicated that the fixed station cannot broadcast the broadcast information to the mobile station at one time, and then the fixed station may split the broadcast information into a plurality of sub-broadcast information, and use each sub-broadcast information as a broadcast data packet and mark a packet number.

It should be noted that the size of each sub-broadcast information is smaller than the predetermined payload size.

Optionally, the broadcast data packet may include: as shown in fig. 3, the payload is broadcast information to be broadcast, the check code is a check mode for ensuring the reliability of data transmission between the fixed station and the mobile station, and generally cyclic redundancy check codes (Cyclic Redundancy Check, CRC) are commonly used to check the broadcast information, that is, the fixed station calculates the broadcast information through a CRC algorithm before broadcasting the broadcast information to the mobile station, so as to obtain a first CRC check code; after receiving the broadcast information, the mobile station also calculates the received broadcast information through a CRC algorithm to obtain a second CRC check code; if the first CRC check code and the second CRC check code are the same, it can be said that the broadcast information broadcast between the fixed station and the mobile station is reliable; if the first CRC check code and the second CRC check code are not identical, it can be stated that the broadcast information broadcast between the fixed station and the mobile station is unreliable, so that the mobile station can delete the received broadcast information.

Illustratively, assume that the fixed station system includes three fixed stations, namely fixed station one, fixed station two, and fixed station three. Before broadcasting the broadcasting information, the three fixed stations obtain a CRC check code 1011 through a CRC algorithm; after receiving the broadcast information broadcast by the first fixed station, the mobile station obtains a CRC check code 1011 through a CRC algorithm, which is the same as the CRC check code of the first fixed station; after receiving the broadcasting information broadcast by the second fixed station, the mobile station obtains 1015 CRC check codes through a CRC algorithm, which are different from the CRC check codes of the second fixed station; after receiving the broadcast information broadcast by the third fixed station, the mobile station obtains a CRC check code 1011 through a CRC algorithm, which is the same as the CRC check code of the third fixed station; thus, the mobile station can discard the broadcast information received from the second fixed station, and only use the broadcast information broadcast by the first fixed station and the third fixed station.

Optionally, the packet header may include: service type, data file type, encryption identifier, packet number, service identifier, fixed station number, reserved identifier; the service types include: data broadcasting, emergency broadcasting, self-defining and the like; the data file types include: DOC, PDF, TXT, etc.; the encryption flag may indicate whether the broadcast information is encrypted; the packet sequence number is the sequence number of the broadcast data packet; the service identifier comprises: text files, short messages, voice messages, etc.; the fixed station number indicates that the current broadcast information is broadcast through a specific fixed station; the reservation flag is used to indicate whether the mobile station is to cache the broadcast information.

203. The fixed station system sequentially transmits a plurality of sub-broadcast information to the mobile stations according to the packet sequence numbers through a plurality of fixed stations.

In the embodiment of the invention, the broadcast information is split into a plurality of sub-broadcast information, and the packet serial numbers are marked in turn, so that each fixed station can broadcast the sub-broadcast information to the mobile stations in turn according to the packet serial numbers.

Illustratively, assume that broadcast information is split into 4 sub-broadcast information and marked sequentially, respectively: first sub-broadcast information 01 number, second sub-broadcast information 02 number, third sub-broadcast information 03 number, fourth sub-broadcast information 04 number. The fixed station may broadcast the first sub-broadcast information No. 01 to the mobile station, broadcast the second sub-broadcast information No. 02 to the mobile station, broadcast the third sub-broadcast information No. 03 to the mobile station, and broadcast the fourth sub-broadcast information No. 04 to the mobile station.

204. The mobile station acquires a plurality of sub-broadcast information broadcast by the target fixed station.

In the embodiment of the invention, the broadcast information is split into a plurality of sub-broadcast information, and the sub-broadcast information is sequentially broadcast to the mobile station through each fixed station, so that the mobile station can receive the sub-broadcast information from each fixed station, and the target fixed station is any one of the plurality of fixed stations.

205. And the mobile station performs merging processing on the plurality of sub-broadcast information according to the packet sequence numbers to obtain the broadcast information broadcasted by the target fixed station.

In the embodiment of the invention, after receiving a plurality of sub-broadcast information broadcast by a target fixed station, a mobile station can sort the plurality of sub-broadcast information according to a packet sequence number included in each sub-broadcast information, and combine the plurality of sub-broadcast information according to the sorting, thereby obtaining the broadcast information of the target fixed station.

Illustratively, suppose that a rover station receives 4 sub-broadcast messages from a fixed station, respectively: 01 "1, 2, 4, 6, 7",02 "8, 9, 13, 15",03 "20, 21",04 "25, 30, 31, 33". The mobile station may sort and combine the 4 sub-broadcast information in the order of 01, 02, 03, 04, thereby obtaining broadcast information "1, 2, 4, 6, 7, 8, 9, 13, 15, 20, 21, 25, 30, 31, 33" of the fixed station-one broadcast.

It should be noted that, the mobile station performs the above-mentioned sequence combining operation after receiving a plurality of sub-broadcast information from each fixed station, so that the mobile station can obtain a plurality of broadcast information corresponding to a plurality of fixed stations.

It should be noted that, since the fixed station broadcasts each sub-broadcast information in turn according to the packet sequence number of each sub-broadcast information, the mobile station also receives the sub-broadcast information in turn, so that the mobile station may wait until all sub-broadcast information is received, then combine all sub-broadcast information, or start combining after receiving two sub-broadcast information, and then combine with the broadcast information that has been combined before once every sub-broadcast information is received.

Illustratively, assume that broadcast information is split into 4 sub-broadcast information and labeled in turn as: 01 "1, 2, 4, 6, 7",02 "8, 9, 13, 15",03 "20, 21",04 "25, 30, 31, 33". The fixed station sequentially broadcasts 4 sub-broadcast information to the mobile station, so that the mobile station receives the number 01, the number 02, the number 03 and the number 04, and the mobile station can sort and combine the 4 sub-broadcast information according to the sequence of the number 01, the number 02, the number 03 and the number 04 after all the 4 sub-broadcast information are received, thereby obtaining broadcast information '1, 2, 4, 6, 7, 8, 9, 13, 15, 20, 21, 25, 30, 31 and 33' broadcasted by the fixed station; the mobile station may also receive the numbers 01 and 02, combine the numbers 01 and 02 to obtain "1, 2, 4, 6, 7, 8, 9, 13, 15", and combine the numbers 03 to obtain "1, 2, 4, 6, 7, 8, 9, 13, 15, 20, 21", and combine the numbers 04 to obtain the broadcast information "1, 2, 4, 6, 7, 8, 9, 13, 15, 20, 21, 25, 30, 31, 33" broadcasted by the fixed station.

Optionally, in the process of acquiring the plurality of sub-broadcast information broadcast by the target fixed station, the mobile station determines the receiving progress in real time according to the packet sequence number of the sub-broadcast information currently received.

It should be noted that, the fixed station system splits the broadcast information into a plurality of sub-broadcast information, and when the packet sequence number is marked for each sub-broadcast information, the total number of the sub-broadcast information is written into the field of the broadcast information at the same time, so that when the mobile station starts to receive the sub-broadcast information, the number of the sub-broadcast information can be known, then the receiving progress can be determined according to the packet sequence number of each sub-broadcast information during the receiving process, and when all sub-broadcast information is detected to have been received, the merging process is started immediately for the plurality of sub-broadcast information.

Because there may be a delay in broadcasting between the fixed station and the mobile station, there may be a time difference between the mobile station receiving each sub-broadcast information, by this alternative implementation, the mobile station may know the progress of receiving the sub-broadcast information in real time, so that the multiple sub-broadcast information may be combined immediately after all the reception is completed, without waiting, and the processing time is reduced.

After the mobile station compares the first broadcast information and the second broadcast information, it can be seen that the first broadcast information and the second broadcast information have repeated broadcast information of '2, 3 and 15', so that the mobile station can delete the repeated broadcast information from the first broadcast information to obtain '1, 4, 5, 7, 9 and 28', and then combine the repeated broadcast information with the second broadcast information to obtain third broadcast information of '1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 15, 18, 19, 28, 29 and 30'; the mobile station may also delete the repeated broadcast information from the second broadcast information to obtain "6, 10, 11, 12, 18, 19, 29, 30", and then combine with the first broadcast information to obtain third broadcast information "1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 15, 18, 19, 28, 29, 30".

Illustratively, assume that the first broadcast information is "1, 2, 3, 4, 5, 7, 9, 15, 28", and the second broadcast information is "6, 10, 11, 12, 18, 19, 29, 30". After the mobile station compares the first broadcast information and the second broadcast information, it can be seen that there is no repeated broadcast information in the first broadcast information and the second broadcast information, and then the mobile station can directly combine the first broadcast information and the second broadcast information to obtain third broadcast information "1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 15, 18, 19, 28, 29, 30".

406. And decrypting the third broadcast information to obtain the target broadcast information.

In the embodiment of the invention, if the mobile station detects that the broadcast information comprises the encryption mark, the broadcast information broadcasted by the fixed station can be indicated to be encrypted, and after the mobile station obtains the third broadcast information, the mobile station can decrypt the third broadcast information, so that the target broadcast information is obtained.

Alternatively, the mobile station may decrypt the third broadcast information via a pre-stored security card.

In the embodiment of the invention, the mobile station can demodulate the broadcast information received from each fixed station, and the mobile station does not always succeed in demodulating the plurality of broadcast information because the broadcast information can be influenced by ionospheric fluctuation, environmental noise and the like in the broadcasting process, so that after the mobile station demodulates the plurality of broadcast information, fourth broadcast information which is successfully demodulated can be possibly obtained, and then the mobile station can store the fourth broadcast information which is successfully demodulated into the data cache; the mobile station may also obtain broadcast information that is not successfully demodulated.

505. And the mobile station performs combination processing on the broadcast information which is not successfully demodulated to obtain fifth broadcast information.
