Description

Alarm message sending method and base station and storage medium

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method for transmitting an SIB11 alarm message in an earthquake tsunami warning system, a base station, and a storage medium.

Background technique

In countries where earthquakes and tsunami occur frequently, it is particularly important to promptly release earthquake and tsunami attacks and evacuation warnings to the public. The lack of information directly threatens life safety. LTE (Long Term Evolution) is a standard for 3GPP (3rd Generation Partnership Project), and supports emergency alert notification of earthquake tsunami through ETWS (Earthquake and Tsunami Warning System). Depending on the degree of urgency and purpose, ETWS will notify the two types of alarms by sending SIB (System Information Block) messages: primary information for earthquake or tsunami (primary notification, carried at SIB10) and evacuation sites and Subsequent information such as materials (Secondary Notification, carried on SIB11) is sent to the public.

The LTE protocol stipulates that the Core Network sets the Repetition Period and the number of transmissions sent by the SIB11. The repetition period sets the time interval between two adjacent SIB11 transmissions, and the number of transmissions sets the number of times that an SIB11 message needs to be repeatedly transmitted. After receiving the SIB11 sent by the core network, the base station sends a paging (referred to as paging-etws) with the indication of the earthquake tsunami warning message and SIB1 (SIB1-etws) with the SIB11 scheduling information, and then sends the SIB11. At the same time, LTE specifies the receiving action of the terminal, that is, immediately after receiving the paging-etws and SIB1-etws, the SIB11 is parsed from the subsequent radio frame until it is resolved to the SIB11. Second, the LTE protocol stipulates that in the SI (System Information) transmission window, the SI can be repeatedly transmitted to increase the probability that the SI is correctly received. SIB11 as SI In part, it can also be sent repeatedly in the SI send window. The repeated transmission interval protocol in the SI window is not explicitly specified, and any subframe in the SI transmission window may repeatedly transmit SI as long as the air interface resource permits.

However, when the SIB11 is delivered in accordance with the LTE protocol, the terminal in the measurement process does not receive the SIB11. The reason for this phenomenon is that the terminal does not receive any data sent by the base station because it is in the measurement process. The measurement time of the terminal in LTE (also referred to as measurement GAP, the time is 6 ms). If the time when the base station repeatedly delivers the SIB11 falls within the measurement time of the terminal, the terminal cannot receive the SIB11 at all times, and the user terminal cannot receive the time in time. The alarm information and evacuation information are caused by the loss of life and property of the people.

detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Various embodiments of the present invention will now be described with reference to the drawings. In the following description, the use of a suffix such as "module" or "step" for indicating an element is merely an explanation for facilitating the present invention, and does not have a specific meaning per se.

The solution of the embodiment of the present invention is that the base station sends the alarm message to the terminal after receiving the alarm message sent by the core network (in this embodiment, the information may be specifically referred to as the SIB11 message); and the alarm is sent in the message sending window where the alarm message is located. The message is repeatedly sent, wherein the time interval of repeated transmission is greater than the measurement time of the terminal measurement process. Therefore, it is ensured that all terminals in the measurement process under the cell can correctly parse the SIB11 message, at least once, so that the SIB11 message is not lost.

Specifically, referring to FIG. 1, FIG. 1 is a schematic flowchart of a method for transmitting an alarm message according to a preferred embodiment of the present invention. As shown in FIG. 1 , the method for sending the alarm message includes:

Step S101: After receiving the alarm message sent by the core network, the base station sends the alarm message to the terminal.

Here, the solution of the embodiment relates to the transmission of the emergency alert notification of the ETWS (Earthquake Tsunami Warning System), wherein the alarm message sent by the core network is mainly auxiliary information such as evacuation sites and materials sent by the ETWS through the core network (Secondary Notification, bearer) In SIB11), hereinafter referred to as SIB11 message.

After receiving the SIB11 message sent by the core network, the base station sends the SIB11 message to the terminal.

In step S102, the alarm message is repeatedly sent in the message sending window where the alarm message is located, wherein the time interval of repeated transmission is greater than the measurement time of the terminal measurement process.

As mentioned before, since the terminal is in the measurement process, it does not receive any data sent by the base station. The measurement time of the terminal in LTE (also referred to as measurement GAP, the time is 6 ms). If the time when the base station repeatedly delivers the SIB11 falls within the measurement time of the terminal, the terminal cannot receive the SIB11 at all times, and the user terminal cannot receive the time in time. The alarm information and evacuation information are caused by the loss of life and property of the people.

Therefore, as a preferred implementation manner, after receiving the SIB11 message sent by the core network and transmitting the SIB11 message to the terminal, the base station first determines whether the terminal is in the measurement process, and if the terminal is in the measurement process, The SIB11 message is repeatedly transmitted in the message sending window (SI sending window) where the SIB11 message is located.

The step of repeatedly sending the alarm message in the message sending window where the alarm message is located includes:

Determining whether the message sending window where the alarm message is located is smaller than the measurement time of the terminal measurement process; if yes, modifying the message sending window where the alarm message is located, so that the message is sent The message sending window where the police message is located is greater than the measurement time of the terminal measurement process;

Then, the alarm message is repeatedly sent in the message sending window where the alarm message is located.

According to the LTE regulations, the measurement time of the terminal measurement process is 6 ms. Therefore, the time interval for repeated transmission of the SIB11 message is greater than the measurement time of the terminal measurement process by 6 ms.

After the SIB11 message is sent by the base station after receiving the SIB11 message sent by the core network, the base station sends the SIB11 message repeatedly in the SI sending window where the SIB11 message is located, and repeats the sending. The interval is greater than the measured GAP, typically greater than 6 ms. This ensures that all terminals in the cell measurement process can correctly parse the SIB11 and receive it at least once.

On the other hand, according to the LTE regulations, the SI transmission window can be configured with the following sizes: 1ms, 2ms, 5ms, 10ms, 15ms, 20ms, 40ms. To ensure that the repeated transmission interval of the SIB11 is greater than 6ms, the configuration size of the SI transmission window needs to be selected as 10ms. , 15ms, 20ms or 40ms, to ensure that SIB11 is sent at least once.

Compared with the prior art:

The transmission window of SIB11 specified by LTE and the timing of repeated scheduling are as follows:

SI发送窗口(ms)SI send window (ms)	SI首次调度时刻SI first dispatch time	SI重复调度时刻SI repeat scheduling moment
11	00	NULLNULL
22	00	11
55	00	1、2、3、41, 2, 3, 4
1010	00	1到9的任意时刻Any time from 1 to 9
1515	00	1到14的任意时刻Any time from 1 to 14
2020	00	1到19的任意时刻Any time from 1 to 19
4040	00	1到39的任意时刻Any time from 1 to 39

Table 1

The scheme of the present embodiment requires the sending window of SIB11 and the timing of repeated scheduling as shown in Table 2 below:

SI发送窗口(ms)SI send window (ms)	SI首次调度时刻SI first dispatch time	SI重复调度时刻SI repeat scheduling moment
1010	00	6到9的任意时刻Any time from 6 to 9
1515	00	6到14的任意时刻Any time from 6 to 14
2020	00	6到19的任意时刻Any time from 6 to 19
4040	00	6到39的任意时刻Any time from 6 to 39

Table 2

In order to ensure the above implementation, the base station needs to increase the SI transmission window check device and the SI transmission window modification device, the SI repeat scheduling check device, and the SI repeat schedule modification device.

When the SIB11 is sent, the SI transmission window check device ensures the SI transmission window. When the SI transmission window length is 1 ms, 2 ms, and 5 ms, the SI transmission window modification device is notified to change the SI transmission window length to be greater than 5 ms, typically 15 ms, 20 ms. 40ms.

After the SI transmission window is corrected, the SI repeat scheduling check device ensures an interval for the SI to repeatedly transmit. If the repetition interval is less than 6 ms, typically 1 ms, 2 ms, 3 ms, 4 ms, the SI repeat scheduling modification device is notified to re-determine the repeated transmission time, typically 6ms, 7ms, etc. until any time before the end of the SI transmission window.

Specific application examples are as follows:

The test environment configuration of this solution is as follows:

Paging cycle: 128 radio frames, ie 1280 ms;

SI send window: 20ms;

The number of times the SIB11 can be repeatedly sent in the SI transmission window: 1 time;

SI period: 8 radio frames, ie 80ms;

SIB11 is configured in the second SI window;

Repetition Period of SIB11: 4s;

Number of Broadcast Requested by SIB11: 3;

The timing of the ETWS transmission mode specified by the LTE protocol is shown in Figure 2.

The time when the base station receives the SIB11 delivered by the core network is time T0 (frame number 220, subframe number 7);

The base station immediately sends the paging-etws and the SIB1-etws, and sends the SIB11 in the sending window of the SI where the subsequent SIB11 is located, that is, the time T1 (frame number 234, subframe number 0), this time is the first time of the SIB11. hair;

The base station repeatedly transmits the SIB11 in the SI window of the first time sending the SIB11, and the interval of repeated transmission is smaller than the terminal measurement GAP, typically 2 ms;

The terminal initiates a measurement process, from (frame number 641, subframe number 8) to (frame number 642, sub-frame number 4);

The second time that the base station sends the SIB11 is the time T2 (frame number 642, subframe number 0), and the repeated transmission is performed on the SIB11 in the SI window of the second transmission SIB11, that is, the time T3 is (frame number 642, subframe) No. 2);

The time T2 at which the base station transmits the SIB11 for the second time and the time T3 that is repeatedly transmitted in the SI transmission window all fall on the measurement GAP time (frame number 641, subframe number 8) of the terminal to (frame number 642, subframe number 4). ), so these two SIB11 will not be resolved by the terminal.

The timing of the ETWS transmission mode of this method is shown in Figure 3.

The base station repeatedly transmits the SIB11 in the SI window of the first sending SIB11, and the interval of repeated transmission is greater than the terminal measurement GAP, typically 7 ms;

The terminal initiates the measurement process, from (frame number 641, subframe number 8) to (frame number 642, sub Frame number 4);

The time when the base station sends the SIB11 for the second time is the time T2 (frame number 642, subframe number 0), and the time for the repeated transmission of the SIB11 in the SI window of the second transmission SIB11 is the time T3 (frame number 642, subframe) No. 7);

The T2 time of the second transmission of the SIB11 by the base station falls within the measurement GAP time (frame number 641, subframe number 8) of the terminal to (frame number 642, subframe number 4), but the repeated transmission T3 in the SI transmission window The time does not fall within the terminal measurement GAP time, so one of the two SIBs 11 will be resolved by the terminal.

As shown in FIG. 2 and FIG. 3, compared with the ETWS transmission mode specified by the LTE protocol, the solution in this embodiment ensures that the terminals in all measurement processes in the cell can correctly parse the SIB11 message.

In the embodiment of the present invention, by correcting the SI transmission window and correcting the repeated transmission interval of the SIB11 in the same SI transmission window, the repeated transmission interval of the SIB11 is greater than the measurement time of the terminal, thereby ensuring that the SIB11 is at least once. The opportunity is correctly received by the terminal, so that the user can receive the alarm message and the evacuation information in time to avoid the loss of life and property of the people. At the same time, since all the above processing steps and modules do not need to modify or change the core network and the terminal, the method and the compatibility of the device with the existing network environment and the terminal are ensured, and the existing communication protocol is not required. Ensure that SIB11 can be received and forwarded in case of any changes. In addition, the difficulty of development and the difficulty and complexity of application deployment are reduced.

Correspondingly, an embodiment of the alarm message sending base station of the present invention is proposed.

As shown in FIG. 4, a preferred embodiment of the present invention provides an alarm message sending base station, including: a first sending module 201 and a second sending module 202, where:

The first sending module 201 is configured to send the alarm message to the terminal after receiving the alarm message sent by the core network;

The second sending module 202 is configured to repeatedly send the alarm message in a message sending window where the alarm message is located, where the time interval of repeated sending is greater than the measuring time of the terminal measuring process.

Specifically, the solution in this embodiment relates to the transmission of the emergency alert notification of the ETWS (Earthquake Tsunami Warning System), wherein the alarm message sent by the core network is mainly auxiliary information such as evacuation sites and materials sent by the ETWS through the core network (Secondary Notification, Beared in SIB11), hereinafter referred to as SIB11 message.

Therefore, the base station may further include:

On the other hand, according to the LTE regulations, the SI transmission window can be configured with the following sizes: 1ms, 2ms, 5ms, 10ms, 15ms, 20ms, 40ms. To ensure that the repeated transmission interval of the SIB11 is greater than 6ms, the configuration size of the SI transmission window needs to be selected as 10ms. , 15ms, 20ms, 40ms, to ensure that SIB11 is sent at least once.

Compared with the prior art:

The transmission window of SIB11 specified by LTE and the timing of repeated scheduling are as shown in Table 1.

The scheme of this embodiment requires that the transmission window of SIB11 and the timing of repeated scheduling are as shown in Table 2 above.

After the SI transmission window is corrected, the SI repeat scheduling check device ensures an interval for the SI to repeatedly transmit. If the repetition interval is less than 6 ms, typically 1 ms, 2 ms, 3 ms, 4 ms, the SI repeat scheduling modification device is notified to re-determine the repeated transmission time, typically 6ms, 7ms, etc. to the SI send window junction Any time before the bunch.

As shown in FIG. 5, the second sending module 202 may include: a determining unit 2021, a correcting unit 2022, and a sending unit 2023, where:

The determining unit 2021 is configured to determine whether the message sending window where the alarm message is located is smaller than the measuring time of the terminal measuring process;

The correcting unit 2022 is configured to: when the determining unit determines that the message sending window where the alarm message is located is smaller than the measuring time of the terminal measurement process, modify the message sending window where the alarm message is located, so that the alarm message is located The message sending window is larger than the measuring time of the terminal measurement process;

The sending unit 2023 is configured to repeatedly send the alarm message in a message sending window where the alarm message is located.

Specific application examples are as follows:

The test environment configuration of this solution is as follows:

Paging cycle: 128 radio frames, ie 1280 ms;

SI send window: 20ms;

SI period: 8 radio frames, ie 80ms;

SIB11 is configured in the second SI window;

Repetition Period of SIB11: 4s;

Number of Broadcast Requested by SIB11: 3;

The base station immediately sends paging-etws and SIB1-etws, and sends SIB11 in the sending window of the SI where the subsequent SIB11 is located, that is, time T1 (frame number 234, subframe number 0), this time is SIB11. First issued;

The timing of the ETWS transmission mode of this method is shown in Figure 3.

The T2 time of the second transmission of the SIB11 by the base station falls within the measurement GAP time (frame number 641, subframe number 8) of the terminal to (frame number 642, subframe number 4), but the weight in the SI transmission window The retransmission T3 time does not fall within the terminal measurement GAP time, so one of the two SIBs 11 will be parsed by the terminal.
