Determine terminal to be broadcasted.Front-end control software in control instruction by carrying emergent broadcast target area in emergency broadcase system
Identification code be sent to terminal, terminal plays the broadcast of response according to the identification code.Wherein identification code needs to meet GB/T2260-
The administrative region digital code requirement of 2007 and GB/T10114-2003.More typical implementation is the identification code of target area
Totally 12, first 6 represent province, city, county respectively according to gb specification setting, and latter 6 are distributed unitedly by local relevant departments.
For example, with reference to Fig. 1, in the identification code structure chart of the target area of emergent broadcast, front two represent province, autonomous region,
Municipality directly under the Central Government, special administrative region code；3rd and the 4th represent city, area, autonomous prefecture, alliance, administrative districts under city administration/county of municipality directly under the Central Government, province/
Autonomous region is directly under the jurisdiction of county's code；5th and the 6th represents county, self-control county, flag, self-control flag, districts under city administration, forest zone, special zone code；7th He
8th represents small towns, street, national town, national countryside, bush coding；9th and the 10th represents administrative village, village, stockaded village's coding；Most
Two represent the coding for the terminal for receiving broadcast, packet number afterwards.
Illustrate the matching principle of the identification code shown in Fig. 1.Assuming that the internal identification code of certain terminal is：10 01 01
01 01 02, then the identification code can matched identification code have：10 00 00 00 00 00 provincial broadcast, 10 01 00
00 00 00 city-level broadcast, 10 01 01 00 00 00 broadcast at county level, 10 01 01 01 00 00 township level broadcast,
10 01 01 01 01 00 at village level broadcast, the broadcast of 10 01 01 01 01 02 terminal.

In a particular embodiment, according to the administrative grade of the target area of emergent broadcast with the user's for issuing emergent broadcast
Administrative grade, determines whether the priority for issuing the user of emergent broadcast is preferential higher than the target area for playing broadcast
Level, including：
According to the target area of emergent broadcast administrative grade height and issue emergent broadcast user administrative grade
Height establish two-dimensional coordinate system, wherein different administrative grades corresponding coordinate points in reference axis are different；
The priority of emergent broadcast is coordinate points according to corresponding to the administrative grade of the target area of emergent broadcast with
What the length of the connecting line between coordinate points corresponding to the administrative grade of the user of hair emergent broadcast determined, the length of connecting line
Longer, the rank of the priority of the target area of emergent broadcast is higher；
Wherein, the principle that cannot be broadcasted according to the region of low administrative grade to the region of high administrative grade, connection should
Coordinate points corresponding to the administrative grade for the target area suddenly broadcasted and issue the emergent broadcast user administrative grade institute
Corresponding coordinate points.
Specifically, establishing includes horizontal and vertical two-dimensional coordinate system, and wherein axis of abscissas represents the target of emergent broadcast
The administrative grade in region, such as represent the use for issuing emergent broadcast including the administrative grades such as province, city, county, township, village, axis of ordinates
The administrative grade at family, such as including administrative grades such as province, city, county, township, villages.Alternatively, axis of ordinates represents the target of emergent broadcast
The administrative grade in region, such as represent the use for issuing emergent broadcast including the administrative grades such as province, city, county, township, village, axis of abscissas
The administrative grade at family, such as including administrative grades such as province, city, county, township, villages.Wherein, in reference axis, administrative grade is higher
The position of the origin of region distance coordinate system is more remote.That is, the higher province of administrative grade is positioned at the farthest of axis of abscissas.Work as foundation
After good coordinate system, connect corresponding to the administrative grade on the point and axis of ordinates corresponding to the administrative grade on axis of abscissas
Point, wherein, it can only be attached according to the principle that the user of low administrative grade cannot be broadcasted to the user of high administrative grade
Point on axis of abscissas and axis of ordinates.For example, when the corresponding administrative grade in the target area of emergent broadcast is saves, then this is emergent
The administrative grade of the target area of broadcast can only be carried out with the administrative grade for the user for issuing emergent broadcast for the administrative grade saved
Connection.Specifically, the priority of emergent broadcast is calculated according to Pythagorean theorem.I.e.：The parameter of the priority of emergent broadcast2=issue
The administrative grade of the user of emergent broadcast2The administrative grade of the target area of+emergent broadcast2.That is, the mesh of emergent broadcast
The length of connecting line between the administrative grade for marking region and the administrative grade for the user for issuing emergent broadcast is longer, corresponding to answer
The priority suddenly broadcasted is higher.
It should be noted that the height for issuing the administrative grade of the user of emergent broadcast can be according to the actual conditions of user
Set.For example, issue the administrative grade of the user of emergent broadcast includes from high to low：Province, city, village, county, township.Wherein, should
The administrative grade for the target area suddenly broadcasted is changeless.
For example, with reference to Fig. 3, built according to the administrative grade of the user for issuing emergent broadcast in " ＞ villages of ＞ townshiies of ＞ counties of ＞ cities of province "
Vertical coordinate system, wherein transverse axis represents the administrative grade of the target area of emergent broadcast, according to " ＞ villages of ＞ townshiies of ＞ counties of ＞ cities of province "
Principle is labeled, and the longitudinal axis represents the administrative grade in the region for the user for issuing emergent broadcast, according to " ＞ townshiies of ＞ counties of ＞ cities of province ＞
The principle in village " is labeled, and connects coordinate points and emergent broadcast corresponding to the administrative grade for the user for issuing emergent broadcast
Target area administrative grade corresponding to coordinate points.Wherein, the administrative grade for issuing the user of emergent broadcast is in township
The administrative grade that the target area of emergent broadcast can be connected be township and administrative grade be village；Issue the user's of emergent broadcast
Administrative grade be the target area that can only connect emergent broadcast in county administrative grade be county, administrative grade be township and administrative
Rank is village, and is high principle according to priority when it is county to issue the administrative grade of user of emergent broadcast, emergent
The administrative grade of the target area of broadcast intercuts the emergent broadcast for the region in county.
According to the schematic diagram of Fig. 3, illustration judges whether the priority for issuing the user of emergent broadcast is higher than and is broadcasting
The method for putting the priority of the target area of broadcast.For example, administrative grade is is playing broadcast in the region in township, it is emergent when having
When broadcast needs to intercut the administrative grade for playing broadcast as in the region in township, and issue the row of the user of the emergent broadcast
When political affairs rank is city, compare coordinate points and emergent broadcast of the administrative grade for the user for issuing the emergent broadcast corresponding to city
Connecting line between coordinate points of the administrative grade of target area corresponding to township, the administration of the user with issuing the emergent broadcast
Rank is that the administrative grade of the target area of the coordinate points and emergent broadcast corresponding to township is between the coordinate points corresponding to township
The length of connecting line, determines according to Fig. 3, and the administrative grade for issuing the user of the emergent broadcast is coordinate points corresponding to city and should
The administrative grade for the target area suddenly broadcasted is the longer of the connecting line between the coordinate points corresponding to township, therefore, meets and issues
The priority of the user of emergent broadcast is higher than the priority for the target area for playing broadcast.
For example, with reference to Fig. 4, according to the administration in the region of the user for issuing emergent broadcast in " ＞ townshiies of ＞ counties of ＞ villages of ＞ cities of province "
Rank establishes coordinate system, and wherein transverse axis represents the administrative grade of the target area of emergent broadcast, according to " ＞ townshiies of ＞ counties of ＞ cities of province ＞
The principle in village " is labeled, and the longitudinal axis represents the administrative grade for the user for issuing emergent broadcast, according to " ＞ counties of ＞ villages of ＞ cities of province ＞
The principle in township " is labeled, and connects coordinate points and emergent broadcast corresponding to the administrative grade for the user for issuing emergent broadcast
Target area administrative grade corresponding to coordinate points.Wherein, the administrative grade for issuing the user of emergent broadcast is in township
The administrative grade that the target area of emergent broadcast can be connected be township and administrative grade be village；Issue the user's of emergent broadcast
Administrative grade be the target area that can only connect emergent broadcast in county administrative grade be county, administrative grade be township and administrative
Rank is village, and is high principle according to priority when it is county to issue the administrative grade of user of emergent broadcast, emergent
The administrative grade of the target area of broadcast intercuts the emergent broadcast for the region in county.
According to the schematic diagram of Fig. 4, illustration judges whether the priority for issuing the user of emergent broadcast is higher than and is broadcasting
The method for putting the priority of the target area of broadcast.For example, administrative grade, which belongs in the region in village, is playing broadcast, should when having
When anxious broadcast needs to intercut the administrative grade for playing broadcast as in the region in village, and issue the user of the emergent broadcast
When administrative grade is city, compare coordinate points and emergent broadcast of the administrative grade for the user for issuing the emergent broadcast corresponding to city
Target area connecting line of the administrative grade between the coordinate points corresponding to village, the row of the user with issuing the emergent broadcast
Political affairs rank is that the administrative grade of the target area of the coordinate points and emergent broadcast corresponding to village is between the coordinate points corresponding to village
Connecting line length, determined according to Fig. 4, issue the emergent broadcast user administrative grade for the coordinate points corresponding to city and
The administrative grade of the target area of emergent broadcast is the longer of the connecting line between the coordinate points corresponding to village, therefore, under meeting
Send out condition of the priority higher than the priority for the target area for playing broadcast of the user of emergent broadcast.And for example, when issuing
When the administrative grade of the user of the emergent broadcast is county, compare the administrative grade for the user for issuing the emergent broadcast corresponding to county
Coordinate points and emergent broadcast target area connecting line of the administrative grade between the coordinate points corresponding to village, with issuing this
The administrative grade of the user of emergent broadcast is that the administrative grade of the target area of the coordinate points and emergent broadcast corresponding to village is village
The length of connecting line between corresponding coordinate points, determines according to Fig. 4, and the administrative grade for issuing the user of the emergent broadcast is
Connecting line between coordinate points of the administrative grade of the target area of coordinate points and emergent broadcast corresponding to city corresponding to village
It is shorter, therefore, issue emergent broadcast user priority be less than playing broadcast target area priority, do not ring
The request of emergent broadcast should be intercutted.
Embodiments above be merely illustrative of the user for how judging to issue the emergent broadcast administrative grade and
The priority of the administrative grade of the target area of emergent broadcast, the invention is not restricted to only be judged with this method.This technology is led
Domain personnel can be judged that the present invention is not specifically limited according to other mathematical model.
In a particular embodiment, in the playback method of above-mentioned emergent broadcast provided in an embodiment of the present invention, terminal judges should
Whether the terminal recognition code for the target area suddenly broadcasted matches with local identification code, if so, then stopping the broadcast playing simultaneously
Intercut the emergent broadcast；Otherwise, it is not responding to the control instruction of front end control module transmission.Specifically, terminal judges that control refers to
Whether minimum administrative grade in the identification code in order, match with local identification code, if matching, emergent broadcast is intercutted in completion
Business.
In a particular embodiment, in the playback method of above-mentioned emergent broadcast provided in an embodiment of the present invention, in control instruction
The only identification code of the terminal of the target area including the highest emergent broadcast of priority-level.
It should be noted that only include the identification code of the target area of emergent broadcast and the knowledge do not intercutted in control instruction
Other content, when terminal receives control instruction, the priority of emergent broadcast is intercutted without judgement, it is only necessary to is determined and local knowledge
After other code is matched, emergent broadcast is intercutted.Therefore, in the playback method of the emergent broadcast provided in the embodiment of the present invention, nothing
By how many emergent broadcasts are issued, the emergent broadcast of highest priority is determined all in accordance with method provided in an embodiment of the present invention
Target area, and the identification code of the terminal of the corresponding target area of the emergent broadcast of highest priority is carried in control instruction
In, it is handed down to the terminal.Therefore, even if the priority of emergent broadcast changes, as long as the identification code changed in control instruction is
Can, terminal need not carry out other unnecessary logic judgments, and no matter how priority changes, and terminal need not modify, therefore,
Reduce the maintenance cost of the terminal after the calculating pressure of terminal, and modification priority.
Below by specific embodiment, the playback method of emergent broadcast provided in an embodiment of the present invention is described in detail.
