Wireless Emergency Alerts (WEA), also known as cmas (commercial Mobile Alert System), is a security System that allows Mobile phones/other Wireless Mobile devices of users in a particular area to receive Alerts that their security will be threatened, and belongs to one of Public Warning Systems (PWS).
WEA services are served by geographic location areas, and many WEA messages only need to be sent to users within a particular geographic location area. For users who are not in a particular geographic area, even if a WEA is received, it need not be displayed to the user.

The application provides a location information updating method of a wireless emergency alarm. Fig. 2 is a flowchart illustrating a location information updating method of a wireless emergency alert according to an embodiment of the present application. In one example, the mobile terminal has performed a SIP registration of an IMS registration procedure, and the network device returns a SIP registration success (SIP 200 OK). As shown in fig. 2, the method for updating location information of a wireless emergency alert of the present embodiment includes the following steps 201 and 206:
In an embodiment of the present application, the request message sent by the mobile terminal in step 202 includes additional position location measurement capability parameters supported by the mobile terminal. The additional location positioning measurement capability parameter is used to inform the network device of the additional location positioning measurement capability supported by the mobile terminal, so that the network device can add the location update parameter of the wireless emergency alert in the response message of step 203 according to the additional location positioning measurement capability parameter supported by the mobile terminal. An example of an additional position location measurement capability parameter included in the request message is as follows:
[Line 1]Subscribe
…
[Line n1]GeographicExtralMeasureCapability：yes
[Line n2]GeographicReportMaxPeriod：24h
[Line n3]GeographicReportMinPeriod：1min
In the first case, when the response message is a response to the request message in step 202, the response message is a first response message responding to the request message. For example, the first response message may be a SIP 200OK, and the network adds a location update parameter field to the SIP 200OK, for example, as follows:
[Line 1]SIP/2.0 200OK
…
[Line n1]GeographicUpdatePeriod：1Hour
[Line n2]GeographicUpdateDistantHighSpeed：5000meter
[Line n3]GeographicUpdateDistantLowSpeed：1000meter
[Line n4]GeographicDetectInterval：10min
[Line n5]GeographicDetectSpeedthreshold：30km/h
…
the parameters in Line n1-n5 are the location update parameters fields. The user can set the number and usage of the parameters included in the location update parameters according to actual needs, which is not limited in the present application.
In the second case, when the response message is a response to the update message in step 206, the response message is a second response message responding to the update message.
In step 204, the mobile terminal checks whether the received response message carries location update parameters of the wireless emergency alert. If so, go to step 205. And if not, ending, the response message is not a response message related to location update of the wireless emergency alert.
In step 206, the mobile terminal sends an update message to the network device. The update message includes the second geographic location of the mobile terminal. The network device receives the update message sent by the mobile terminal and saves the second geographic location, and executes step 203.
In summary, the location information updating method for the wireless emergency alert according to the embodiment of the present application implements simple, timely, and accurate update of the geographic location information of the mobile terminal required by the WEA to the network by carrying the geographic location information of the mobile terminal in the request message and the update message for initiating the WEA subscription service.
Fig. 3 is a flowchart illustrating a location information updating method of a wireless emergency alert according to another embodiment of the present application. In one example, the mobile terminal has performed a SIP registration of an IMS registration procedure, and the network device returns a SIP registration success (SIP 200 OK). As shown in fig. 3, the method for updating location information of a wireless emergency alert of the present embodiment includes the following steps 301-307:
In the first case, when the response message is a response to the request message in step 302, the response message is a first response message responding to the request message. For example, the first response message may be a SIP 200OK, in which the network adds a location update parameters field.
In the second case, when the response message is a response to the update message in step 307, the response message is a second response message responding to the update message. The location update parameters carried by the second response message further include a preset first moving state reporting parameter, a preset second moving state reporting parameter, or a preset third moving state reporting parameter. The first motion state reporting parameter, the second motion state reporting parameter and the third motion state reporting parameter are used for indicating how the mobile terminal reports the geographical position.
In step 304, the mobile terminal checks whether the received response message carries location update parameters of the wireless emergency alert. If so, go to step 305. And if not, ending, the response message is not a response message related to location update of the wireless emergency alert.
And step 306, the mobile terminal stores the location updating parameter, and obtains the current second geographic location and determines the motion state according to the location updating parameter. The motion state is divided into three states of a first motion state, a second motion state and a third motion state. The average motion rate corresponding to the first motion state is greater than the average motion rate corresponding to the second motion state, and the average motion rate corresponding to the second motion state is greater than the average motion rate corresponding to the third motion state. In one example, the first motion state may be referred to as a high-speed motion state, the second motion state may be referred to as a low-speed motion state, and the third motion state may be referred to as an ultra-low-speed motion state.
In an embodiment of the present application, the mobile terminal may determine the motion state by: the mobile terminal measures the instantaneous speed, then calculates the average movement speed based on the time for acquiring the first geographical position, the time for acquiring the second geographical position, the first geographical position and the second geographical position, and finally determines the movement state based on the preset condition and the average movement speed. In one example, the time when the mobile terminal acquires the first geographic location is denoted as T1, the time when the mobile terminal acquires the second geographic location is denoted as T2, the first geographic location is denoted as P1, the second geographic location is denoted as P2, and the current instantaneous velocity of the mobile terminal is denoted as Vt, then the mobile terminal position offset L1 is P2-P1, and the mobile terminal average motion velocity V is L1/(T2-T1). In an embodiment of the present application, the preset condition for determining the motion state may be preset in the mobile terminal, or may be issued to the mobile terminal by the network device through the location update parameter, which is not limited in this application. In an embodiment of the present application, the preset condition may include a judgment threshold of each motion state. The network can determine the threshold according to the motion state of the mobile terminal and the size of the cell coverage area, and the terminal performs evaluation reporting according to the setting of the network. The network selects and sets the terminal reporting threshold by matching the cellular network wireless emergency alarm area with the terminal motion state, so that the terminal can be prevented from reporting and updating the geographic position too frequently, the terminal can be ensured to update the position information in time, the wireless emergency alarm service provided by the network is more accurate, and the LCS positioning load of the network side can be reduced.
The following describes an example of the steps of determining the motion state of the mobile terminal:
and if the average motion speed V of the mobile terminal is greater than or equal to the high-speed motion state threshold GeogaphsicUpdateDistantHighSpeed in the preset condition, determining that the mobile terminal enters the high-speed motion state. The high-speed motion state may be used to indicate that, due to the high motion rate of the mobile terminal, the distance between the first reporting of the geographical location and the second reporting of the geographical location is long, and the first geographical location and the second geographical location are in different network areas. And the terminal reports the current geographical position through the updating message.
And if the average motion speed V of the mobile terminal is less than the high-speed motion state threshold but greater than or equal to the low-speed motion state threshold GeographicUpdateDistantLowSpeed in the preset condition, determining that the mobile terminal enters the low-speed motion state.
And if the average motion speed V of the mobile terminal is less than the threshold GeogrAN _ SNhicicUpdateDistantLowSpeed of the ultra-low-speed motion state in the preset condition, determining that the mobile terminal enters the ultra-low-speed motion state.
when the mobile terminal is in a high-speed motion state, the mobile terminal may transmit an update message as follows:
[Line 1]UPDATE…
…
[Line n1]Geolocation:32.863221(deg)-97.104122(deg)153.90(m)
[Line n2]average velocity：Vt
[Line n3]Instantaneous velocity：V
[Line n4]velocitytype：high
…
when the mobile terminal is in a low-speed motion state, the mobile terminal may transmit an update message as follows:
[Line 1]UPDATE…
…
[Line n1]Geolocation:32.863221(deg)-97.104122(deg)153.90(m)
[Line n2]average velocity：Vt
[Line n3]Instantaneous velocity：V
[Line n4]velocitytype：mid
…
when the mobile terminal is in the ultra-low speed motion state, the mobile terminal may transmit an update message as follows:
[Line 1]UPDATE…
…
[Line n1]:32.863221(deg)-97.104122(deg)153.90(m)
[Line n2]average velocity：Vt
[Line n3]Instantaneous velocity：V
[Line n4]velocitytype：staticorveryslow
…
after the mobile terminal sends the update message, the network device receives the update message, and performs step 303, where the response message in step 303 is a second response message responding to the update message. And the location update parameter in the second response message is determined based on the motion state in the update message. In one example, the second response message may be an Update 200 OK.
In an embodiment of the present application, when the motion state in the update message is the first motion state, the location update parameter carried in the second response message includes a first motion state reporting parameter; when the motion state in the update message is a second motion state, the position update parameter carried by the second response message comprises a second motion state reporting parameter; and when the motion state in the update message is the third motion state, the position update parameter carried by the second response message comprises a third motion state reporting parameter.
The following still takes the high-speed motion state, the low-speed motion state, and the ultra-low-speed motion state as examples to illustrate the second response message:
when the motion state in the update message is the first motion state, the network considers that the mobile terminal is always in the high-speed motion state, and considers that the interval of reporting the position by the mobile terminal needs to be reduced, at this time, the network device may send a second response message as shown below:
[Line 1]SIP/2.0 200OK
[Line n1]GeographicUpdatePeriod：1Hour
[Line n2]GeographicUpdateDistantHighSpeed：5000meter
[Line n3]GeographicUpdateDistantLowSpeed：1000meter
[Line n4]GeographicDetectInterval：5min
[Line n5]GeographicDetectSpeedthreshold：30km/h
when the motion state in the update message is the second motion state, the network considers that the mobile terminal is always in the low-speed motion state, and considers that the interval of reporting the position by the mobile terminal needs to be increased appropriately, at this time, the network device may send a second response message as shown below:
[Line 1]SIP/2.0 200OK
[Line n1]GeographicUpdatePeriod：1Hour
[Line n2]GeographicUpdateDistantHighSpeed：5000meter
[Line n3]GeographicUpdateDistantLowSpeed：1000meter
[Line n4]GeographicDetectInterval：20min
[Line n5]GeographicDetectSpeedthreshold：30km/h
when the motion state in the update message is the third motion state, the network considers that the mobile terminal is always in the ultra-low speed or relatively stationary motion state, and considers that the interval of reporting the position by the mobile terminal needs to be greatly increased, and at this time, the network device may send a second response message as shown below:
[Line 1]SIP/2.0 200OK
[Line n1]GeographicUpdatePeriod：1Hour
[Line n2]GeographicUpdateDistantHighSpeed：5000meter
[Line n3]GeographicUpdateDistantLowSpeed：1000meter
[Line n4]GeographicDetectInterval：60min

the network can dynamically adjust the motion mode of the mobile terminal according to the condition that the mobile terminal reports for many times, and can comprehensively consider the motion mode according to the current time and the historical motion rule.
In summary, the location information updating method of the wireless emergency alert according to the embodiment implements simple, timely, and accurate updating of the geographic location information of the mobile terminal required by the WEA to the network by carrying the geographic location information of the mobile terminal in the request message and the update message for initiating the WEA subscription service. In addition, by setting the timer and determining the motion state of the mobile terminal, the mobile terminal is prevented from reporting and updating the geographical position too frequently, and the mobile terminal can be ensured to update the position information in time, so that the wireless emergency alarm service provided by the network is more accurate, and the LCS positioning load of the network side can be reduced.
For the types of terminals that do not support positioning measurement methods such as GPS, there may be many choices for the acquisition method of the geographic location information, and several feasible acquisition methods of the geographic location information are described below.
If the Wi-Fi hotspot supports GPS positioning measurement and supports GPS information sharing or broadcasting, the mobile terminal acquires from the Wi-Fi hotspot. An HTTP server exists in Wi-Fi, and the terminal is supported to acquire GPS position information. The terminal sends an HTTP GET request to the existing HTTP server in the Wi-Fi as follows:
…
GET/GPS/common/HTTP/1.1
…
and after the HTTP server in the Wi-Fi receives the HTTP GET request, checking the cached GPS position information and the acquisition time. If the GPS position information is acquired within the time T2 of the latest acquisition of the second geographic position and meets the freshness requirement, the GPS position information is directly used; if the freshness requirement is not met, GPS measurements are turned on to reacquire the geographic location. The HTTP server in Wi-Fi responds to HTTP 200OK, carrying GPS information, with the following responses:
if the Wi-Fi hotspot supports connection to a cellular mobile network (1G, 2G, 3G/4G/5G/…) and cellular mobile network information sharing or broadcasting is supported, the terminal acquires the cellular mobile network information from the Wi-Fi hotspot. An HTTP server exists in the Wi-Fi, and the terminal is supported to acquire the information. If the resident PLMN and the PLMN established by the terminal are different, the Wi-Fi hotspot can start background search to search the PLMN cell information established by the terminal. The mobile terminal may send an HTTP GET request to the Wi-Fi hotspot as follows:
…
GET/3gppcellinfo/common/HTTP/1.1
…
PLMN:31016 31020-31031 31058 31066 31080
…
after the HTTP server in the Wi-Fi receives the HTTP GET request, the cached cellular mobile network information and the cached acquisition time are checked, and if the cellular mobile network information meets the requirement, the cellular mobile network information is directly used; if not, starting the cellular mobile network measurement to acquire the geographic position again, and then selecting to close the cellular mobile network. The HTTP server in Wi-Fi responds to HTTP 200OK and carries cellular mobile network information, which is specifically exemplified as follows:
if the network does not support a connection to a cellular mobile network, either 404 or other types of errors may occur, or the HTTP does not respond and the TCP connection does not handshake. The number of consecutive failures may be recorded in a variable N, where N is incremented by 1 after a failure and is set to 0 after a success. And when the N is greater than a certain threshold M, judging that the non-continuity non-recoverable failure occurs, and then the mobile terminal can consider that the Wi-Fi service does not support, and then does not request any more. The value of M may be a positive integer value such as 5, which is not limited in this application.
If the Wi-Fi hotspot does not support GPS or is connected to a cellular mobile network, the geographical location may be obtained by means of other GPS-enabled or mobile cellular network-connected terminals that have registered on the Wi-Fi hotspot. Other terminals need to support the equipment of the wireless emergency alert geographical location information sharing service, and the registration process is as follows;
the mobile terminal sends an HTTP POST request to another terminal, and the registration supports providing a wireless emergency alert geographical location information sharing service, which is specifically exemplified as follows:
and after the HTTP server in the Wi-Fi receives the HTTP POST request, recording the capability provided by the equipment. A request to provide wireless emergency alert geographical location information may then be transmitted from the terminals.
After receiving the mobile terminal positioning request, the HTTP server in the Wi-Fi checks whether other registered mobile terminals exist, if so, selects other mobile terminals UE2 according to the residual battery power, and forwards the regular request to the UE 2. The UE2 performs positioning measurements or directly returns GPS or CELLINFO information that meets freshness requirements. Additionally, the geographic location provided by the UE2 may also be evaluated for trustworthiness scores, with the notification indicating a network trust score.
If the Wi-Fi server does not support GPS or is connected to a cellular mobile network and no other terminal provides similar services, the mobile terminal may acquire a geographical location by performing indoor positioning.
In addition, the terminal can allow the client to attach the wireless emergency alert information of the region of interest by himself/herself, so that the wireless emergency alert information of the region of interest can be received even if the terminal is located in a place other than the region of interest. The mobile terminal may specify the region of interest itself, for example as shown in the following table:
the mobile terminal may update the region of interest to the server through a subscription (Subscribe). When the wireless emergency alert information is prompted, a corresponding explicit prompt for the area of interest is required, for example, as follows:
region of interest: a. the
Wireless emergency alert information: XXXXXX
The mobile terminal can execute local positioning by accessing the cellular mobile network through the WIFI server, using the GPS and sharing the geographical position information of other terminals and the like, so that the positioning load of the network is reduced.
