Description
Technical Field
The invention relates to the field of communication, in particular to a system message receiving and transmitting method of an earthquake and tsunami early warning system.
Background
In order to actively cope with natural disasters such as earthquake and Tsunami, it is necessary to establish an ETWS (earthquake and Tsunami Warning System). By using the system, disaster-related information can be timely sent to the user when the earthquake and tsunami natural disaster occurs, so that the influence of the earthquake and tsunami natural disaster on human beings is reduced.
Fig. 1 is a network structure diagram of a PLMN (public land mobile network) operator providing users with an earthquake and tsunami warning service through an ETWS system. When a disaster event is about to occur or occurs, a government or other organizations issue an alarm notification to a PLMN operator, and the PLMN operator sends an alarm notification message to a large number of users through an ETWS system contained in a virtual frame. The alarm notification message can be classified into two types according to the degree of urgency and the purpose: the first type of notification message is called Primary notification message (Primary notification), and the message has the most important disaster information (such as the impending earthquake or tsunami), and the system is required to transmit the message to the user within 4 s; a second type of notification message is called a secondary notification message (secondary notification), which contains auxiliary information related to the disaster (e.g., where assistance can be obtained, etc.), requiring the system to deliver the message to the user in 10s to 30 s. The contents of the ETWS primary notification message and the secondary notification message are broadcasted in system messages, and the base station notifies the UE to read the system messages through a paging message paging.
In an LTE (Long Term Evolution) system, a paging message of an ETWS main notification message is immediately sent in a current system message modification period. Fig. 2 generally depicts an ETWS main notification message paging message and system message time relationship, in which SIB1 (system message block 1) is mapped to SI-1, SIB10 is mapped to SI-6, the squares with the twilled grid indicate the messages (blocks) that the terminal needs to process, and the blank squares indicate the messages (blocks) that the terminal ignores. As shown in the figure, if the paging cycle (320ms) is less than or equal to the scheduling cycle (640ms) of the ETWS main notification message system information, then it may happen that the terminal receives a paging message (see the two paging messages after the paging part in fig. 2) when it has not successfully resolved the ETWS main notification message system information, and since the terminal does not know that this paging message is a repetition of the previous paging message at this time, the terminal considers the paging message as a paging message of a new ETWS system message (e.g. an earthquake occurs again) when receiving the new paging message, since there is scheduling information of SIB10 only in SIB1, the terminal needs to listen to SIB1 immediately, and if SIB1 and SIB10 overlap in time, the terminal misses the opportunity to read SIB 10.
Fig. 3 illustrates this case from the granularity of a frame, where the blank squares represent SIBs, the squares with diagonal grid represent paging messages received by the terminal, and the squares with horizontal and vertical grid represent SIB 10. In the figure, the UE receives the ETWS main notification message paging message at SFN (System Frame number) n +4, and then in order to know the System information scheduling situation of the ETWS main notification message, the UE receives SIB1 at SFN n +6, and SIB10 appears at SFN n +5, and after the paging message, because the UE does not know the scheduling information of SIB10 at the transmission time of SIB10, the UE misses the scheduling time for receiving SIB 10. And since the paging message, SIB10 are periodically scheduled, and the period of SIB10 is an integer multiple of the paging period, this is true for these UEs for each reception of the paging message and the time relationship of SIB10 until the paging message stops being transmitted. This results in the UE successfully detecting SIB10 waiting until all paging messages have been sent, which is at least one system message modification period, and therefore must exceed 4 s. This is not enough for accurate reception by the UE in the ETWS main notification message 4 s.
Fig. 4 depicts a similar problem for ETWS secondary notification message system information reception. Since paging continues until the next system message modification period, the terminal receives a page again in period n +1, and similarly, the terminal does not know that the page is a repetition of the previous page, and then starts to read SIB11 in period n +2, which causes the terminal to delay receiving the ETWS secondary notification message by one system modification period.

Detailed Description
The technical solution of the present invention will be described in more detail with reference to the accompanying drawings and examples.
The present invention provides three solutions to the above-mentioned problem caused by receiving multiple paging messages before the terminal successfully and completely resolves the ETWS primary notification message and the secondary notification message.
Herein, the paging message of the ETWS system message refers to: the paging message is used for carrying an ETWS system message, which includes related information of the ETWS primary notification message and the ETWS secondary notification message, and may also carry other paging information, such as other system message modification indication information or dedicated paging information for the UE.
The first scheme is as follows: the method for receiving the system message of the earthquake and tsunami warning system by the terminal comprises the following steps:
if the terminal receives paging messages of a plurality of ETWS system messages within a continuous period of time, the terminal ignores the paging messages of the latter ETWS system messages.
The receiving method comprises the following steps:
after the terminal successfully receives the paging message of the ETWS system message for the first time, reading the ETWS system message according to the scheduling information of the ETWS system message in the SIB 1; when the terminal receives the paging message of the ETWS system message in a continuous period of time, the ETWS system message is not read;
the length of the continuous period of time is not less than the length of the period of time from the terminal receiving the paging message of the ETWS system message to the terminal being capable of reading the ETWS system message.
Wherein, the length of the continuous period of time may be equal to the length of one or more system message modification periods, or may be equal to the length of a scheduling period of the ETWS system message.
Wherein, not reading the ETWS system message means: not re-listening to scheduling information of the ETWS system message in SIB 1; that is, at this time, if the terminal has not read SIB1 after receiving the paging message of the ETWS system message for the first time, it continues to listen to SIB 1; and if the reading is already carried out, monitoring the SIB carrying the ETWS system message according to the scheduling information of the ETWS system message in the SIB 1.
It should be noted that, the "when the terminal receives the paging message of the ETWS system message within a continuous period of time thereafter, the terminal does not read the ETWS system message" is for the ETWS system message, and if there is other paging information in the paging message of the ETWS system message, the terminal still processes the "other paging information" according to the existing manner.
The paging message of the ETWS system message may be a paging message for an ETWS primary notification message, or a paging message for an ETWS secondary notification message.
And the UE judges that the paging message is the paging message of the ETWS main notification message according to the ETWS main notification message existing identifier in the paging message as True.
Wherein, the UE can determine that the paging message is the paging message of the ETWS secondary notification message according to the ETWS secondary notification message existence flag in the paging message being True; or the paging message may be determined to be the ETWS secondary notification message according to the system message modification identifier in the paging message, the value tag (value identifier) in SIB1, and the scheduling information for the secondary notification message in SIB 1.
Wherein, if the paging is for the ETWS secondary notification message, the length of the ETWS system message period refers to the system message period carrying the ETWS secondary notification message segment multiplied by the number of segments.
The second scheme is as follows: a configuration method of ETWS system message period includes:
the length of the scheduling period of the ETWS system message is configured to be smaller than the length of the paging period.
The invention also correspondingly provides a transmission method of the ETWS system message, which comprises the following steps:
configuring the length of a scheduling period of an ETWS system message to be less than the length of a paging period;
the base station sends a paging message of the ETWS system message, sends the ETWS system message in a corresponding system message block, and carries scheduling information of the ETWS system message in a system message block 1.
The transmission method may further include:
and after receiving the paging message of the ETWS system message, the terminal receives the ETWS system message according to the scheduling information of the ETWS system message in the system message block 1.
Wherein, the ETWS system message may be a system message of an ETWS primary notification message, or may be a system message of an ETWS secondary notification message.
Wherein, if the ETWS system message is a system message of the ETWS secondary notification message, the length of the scheduling period of the ETWS system message refers to the system message period carrying the ETWS secondary notification message segment multiplied by the number of segments.
In the third scheme: a method for receiving an earthquake and tsunami warning system message by a terminal comprises the following steps:
after the terminal receives the paging message of the ETWS system message, the terminal still receives the corresponding ETWS system message according to the corresponding scheduling information in the SIB1 that has been received before the scheduling information of the corresponding ETWS system message in the next SIB1 is not correctly received.
The paging message of the ETWS system message may be a paging message for an ETWS primary notification message, or a paging message for an ETWS secondary notification message.
The ETWS system message may be a system message of an ETWS primary notification message, or may be a system message of an ETWS secondary notification message.
Three examples of the present invention are further described below.
Application example one, the application example is a specific embodiment of the first method described above.
As shown in fig. 5, the squares with diagonal grid indicate the messages (blocks) that the terminal needs to process, the blank squares indicate the messages (blocks) that the terminal ignores, the SIB carrying the ETWS main notification message is SIB10, SIB10 is mapped to SI-6, the scheduling period of SI-6 is 640ms, and offset by 40 ms. The system message modification period of the cell is 5.12s, and the paging period is 320 ms. The UE reads the ETWS primary notification message only when the ETWS primary notification message received for the first time is paged within one system message modification period time, i.e., within 5.12 s.
In fig. 5, when an earthquake occurs, the UE supporting the ETWS function receives the ETWS main notification message paging message (see the black part of paging in fig. 5) from the base station, and the UE immediately starts listening to SIB1 (see the black part of SI-1 in fig. 5), and SIB1 has the scheduling information of SIB 10. The UE listens to SIB10 information according to the scheduling information of SIB10 in SIB 1. Before the UE receives the SIB10 information, the UE receives two ETWS main notification messages paging messages, but the UE determines that the time lengths of the two paging messages from the time when the UE receives the paging message for the first time are 320ms and 640ms, respectively, and do not exceed 5.12s, so the UE ignores the two paging messages. The UE receives SIB10 (see the black part of SI-6 in fig. 5) according to the scheduling information of SIB10 in SIB1 that has been received, after approximately 640ms after receiving the first paging message, and completes the reception of the ETWS main notification message.
In this example, the delay of receiving the ETWS primary notification message is equal to the period of SIB10 being 640ms, which satisfies the delay requirement of 4 s.
Application example two, which is a specific embodiment of the above-described second method.
As shown in fig. 6, the squares with diagonal grid indicate the messages (blocks) that the terminal needs to process, the blank squares indicate the messages (blocks) that the terminal ignores, the SIB carrying the ETWS main notification message is SIB10, SIB10 is mapped to SI-6, the scheduling period of SI-6 is 320ms, and is offset by 40 ms. The system message modification period of the cell is 5.12s, and the paging period is 640 ms. Thus the period of SI-6 is shorter than the paging period.
In fig. 6, when an earthquake occurs, the UE supporting the ETWS function receives the ETWS main notification message paging message (see the black part of paging in fig. 6) from the base station, and the UE immediately starts listening to SIB1 (see the black part of SI-1 in fig. 6), and SIB1 has the scheduling information of SIB 10. The UE listens to SIB10 information according to the scheduling information of SIB10 in SIB 1. The UE receives SIB10 (see the black part of SI-6 in fig. 6) according to the scheduling information of SIB10 in SIB1 that has been received, approximately 320ms after receiving the first paging message, and completes the reception of the ETWS primary notification message.
In this example, the delay of receiving the ETWS primary notification message is equal to the period of SIB10 being 320ms, which satisfies the delay requirement of 4 s.
Application example three, the application example is a specific embodiment of the third method described above.
As shown in fig. 7, the squares with diagonal grid indicate the messages (blocks) that the terminal needs to process, the blank squares indicate the messages (blocks) that the terminal ignores, the SIB carrying the ETWS main notification message is SIB10, SIB10 is mapped to SI-6, the scheduling period of SI-6 is 640ms, and offset by 40 ms. The system message modification period of the cell is 5.12s, and the paging period is 320 ms.
In fig. 7, when an earthquake occurs, the UE supporting the ETWS function receives the ETWS main notification message paging message (see the black part of paging in fig. 7) from the base station, and the UE immediately starts listening to SIB1 (see the black part of SI-1 in fig. 7), and SIB1 has the scheduling information of SIB 10. The UE listens to SIB10 information according to the scheduling information of SIB10 in SIB 1. After 320ms from the first paging message, the UE receives the second ETWS primary notification message paging message, re-reads the scheduling information about SIB10 in SIB1, and continues to listen to SIB10 information. After 640ms from the reception of the first paging message, the UE receives the third ETWS primary notification message paging message, does not receive the SIB1 information at the next SIB1 time, receives the SIB10 (see the black part of SI-6 in fig. 7) according to the scheduling information of the SIB10 in the SIB1 that has been received, and completes the reception of the ETWS primary notification message.
In this example, the delay of receiving the ETWS primary notification message is equal to the period of SIB10 being 640ms, which satisfies the delay requirement of 4 s.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
