Background technique

The GEO satellite is located 30,000 kilometers above the equator, and its trajectory is relatively stationary with the earth. Due to the wide coverage area of GEO satellite beams, spot beams can provide communication services to areas that cannot be covered by ground mobile communication systems, such as oceans and wilderness.

GEO satellite systems generally use a combination of space division, frequency division and time division multiplexing technologies to provide terminal access services through large-aperture antennas and limited transponder output power. Due to the large coverage area of satellite spot beams, local emergency numbers cannot be dialed based on the location of the terminal.

1. Screenshot of configuration interface

In the Tiantong project, the latitude and longitude information is first mapped to the location area (mobile country code + mobile network code + local area) code, and then the called number is translated into a location-based number through call source analysis and number analysis configuration. landing number;

①Setting area number configuration

As shown in Figure 4:

For records with a location area number (corresponding to a certain longitude and latitude) of 27 (mobile country code, mobile network code, and local area code are: 460, 34, and 2032 respectively), the corresponding call source code is configured as 2;

②Call source analysis configuration

As shown in Figure 5:

For records with call source code 1, the corresponding called prefix set is 0;

A record with a call source code of 2 corresponds to a called prefix set of 2;

③Number analysis (translation) configuration

As shown in Figure 6 and Figure 7:

When the user dials emergency call number 119 (called prefix 119), for called prefix set 2 (corresponding to call source code 2), the matching number translation strategy is: add 010 before the called number ("add" 010 );

When the user dials emergency call number 119 (called prefix 119), for other (any: including 0) called prefix sets (which can correspond to call source code 1), the matching number translation strategy is: directly replace it with 17400000002.

Among them, the emergency call implemented by this configuration is as follows:

1. After making the above configuration on the ground gateway station network management: When the user moves to a certain longitude and latitude in the area (for example: longitude: 116.43. Latitude: 39.92.), the location area number corresponding to the longitude and latitude is 27 (moving country code, Mobile network code and local area code are: 460, 34, 2032 respectively)

2. The user initiates an emergency call to 119;

3. The satellite ground access network carries the latitude and longitude (longitude: 116.43. Latitude: 39.92.) to the ground satellite gateway station;

4. The satellite gateway station searches the "Location Area Configuration" table: the matched call source code is 2;

5. The satellite gateway station searches the "Call Source Analysis Configuration" table: the called prefix set is matched to 2;

6. The satellite gateway station searches the "Number Analysis Configuration" table: According to the called number 119 and the called prefix set is 2, the matching number translation strategy is: add 010 before the called number and translate the number to 010119;

7. According to the called landing number 010119, the core network routes the number to the PSTN network.

Working principle: When the satellite mobile communication terminal initiates services (location update, making or receiving calls, data services, sending and receiving text messages, etc.), the core network obtains the relevant information of the UE location (satellite) from the access network GSC based on the Iu interface specified by 3GPP. The user's longitude and latitude), the core network determines the location area according to the location and performs the number translation strategy.
