Example 1
Fig. 1 is a flowchart of a method for determining a synchronization object of tracking area codes according to an embodiment of the present application. As shown in fig. 1, the method specifically comprises the following steps:
s101, acquiring a tracking area code currently registered by each terminal device in a current cell;

Based on the above usage scenario, it can be appreciated that the execution subject of the present application may be an NTN management platform. Specifically, the acquisition of the tracking area code of each terminal device, the identification of whether the tracking area code is in the tracking area code list, the determination of the target device, and the like may be performed by the NTN management platform, and the target device updates the communication configuration information after receiving the tracking area code list.
The terminal device may refer to an electronic device having computing power and internet connection capability, such as a desktop computer, a notebook computer, a mobile phone, a tablet computer, an interactive multimedia device, and the like.
NTN (Non-Terrestrial Network ) refers to a network that provides wireless communication services using Non-traditional means (e.g., satellites, airships, drones, etc.). Compared with the traditional ground network, the NTN has the advantages of wide area coverage, quick deployment, elastic expansion and the like, and can provide communication service in remote areas, disaster areas or temporary activities. An NTN cell refers to a communication unit established in NTN.
The NTN management platform may be a centralized control platform based on a satellite server for helping the terminal device to establish NTN connections with satellites. Wherein satellite server refers to a server device deployed on a satellite for processing and providing satellite communications and data services.
Tracking area is a concept in mobile communication networks for managing and tracking the location and connection of terminal devices. The coverage area may be divided into a plurality of tracking areas, each consisting of a set of base stations, responsible for providing wireless signal coverage and service. The terminal device may be in a tracking area for a certain time.
Tracking areas are typically identified and identified by tracking area codes, each tracking area having a unique tracking area code.
And sending a tracking area code request to each terminal device in the current cell, sending the currently registered tracking area code as a response of the request after each terminal device receives the tracking area code request, and obtaining the currently registered tracking area code of each terminal device in the current cell by receiving response data sent by each terminal device.
S102, identifying whether the tracking area code of the current terminal equipment is in a tracking area code list of the current cell;
one NTN cell may cover multiple tracking areas simultaneously, so each NTN cell corresponds to a tracking area code list comprising multiple tracking area codes. Along with the movement of the NTN cell, the tracking area related to the coverage of the NTN cell changes, and correspondingly, the tracking area code list corresponding to the NTN cell changes dynamically.
By using a character matching algorithm, matching the tracking area code of the current terminal device with each tracking area code in the tracking area code list of the current cell, if the tracking area code list of the current cell has the successfully matched tracking area code, identifying that the tracking area code of the current terminal device is in the tracking area code list of the current cell, and if the tracking area code list of the current cell does not have the successfully matched tracking area code, identifying that the tracking area code of the current terminal device is not in the tracking area code list of the current cell.
The character matching algorithm is an algorithm for searching specific characters or substrings in a character string, and common character matching algorithms comprise a naive character string matching algorithm, a KMP (Knuth-Morris-Pratt) algorithm, a BM (Boyer-Moore) algorithm, a double-loop algorithm and the like.
The following is an example code that enables identifying whether the tracking area code of the current terminal device is in the tracking area code list of the current cell:
def match_tracking_area_code(tracking_area_code, tracking_area_code_list):
for code in tracking_area_code_list:
if code == tracking_area_code:
return True
return False
example tracking area code list
tracking_area_codes = ["001", "002", "003", "004"]
Tracking area code for current terminal equipment
current_tracking_area_code = "003"
Tracking area code of # matching current terminal equipment and tracking area code list
is_matched = match_tracking_area_code(current_tracking_area_code, tracking_area_codes)
if is_matched:
print ("tracking area code of current terminal device in tracking area code list of current cell")
else:
print ('tracking area code of current terminal equipment is not in tracking area code list of current cell')
In the above example, the 'match_tracking_area_code' function accepts two parameters: the tracking_area_code 'is the tracking area code of the current terminal device, and the tracking_area_code_list' is a given tracking area code list. The function compares each tracking area code in the list with the tracking area code of the current terminal device through iteration, if the matching tracking area code is found, the 'True' is returned, otherwise the 'False' is returned.
S103, determining the terminal equipment of which the tracking area code is not in the tracking area code list as target equipment;
the target device refers to a terminal device that needs to update the registered tracking area code to meet the communication requirement.

Wherein the device identification may be an identifier for uniquely determining the terminal device.
S104, unicast the tracking area code list of the current cell to the target equipment.
Unicast refers to a way of communicating one-to-one in a network. In unicast communication, information is sent to only one particular recipient, not to all devices.
The tracking area code list may be transmitted by the satellite to the target device over a satellite link. The satellite link refers to a communication connection established between a satellite and a terminal device through a wireless signal.

The update request refers to information transmitted by the target device for updating the tracking area code registered by the target device. An update request sent by the target device may be received over the satellite link.
The communication configuration information may refer to a tracking area code registered by the terminal device and other communication configuration parameters, and the other communication configuration parameters may include a communication protocol, a data transmission rate, a communication frequency band, and the like.
And after receiving the update request sent by the target device, sending the current tracking area code list to the target device as a response of the update request. The target device selects the first tracking area code in the tracking area code list as the newly registered tracking area code, and correspondingly adjusts other communication configuration parameters according to the newly registered tracking area code.
The advantage of this arrangement of the scheme is that by receiving the update request sent by the target device, the target device can be assisted in updating the communication configuration information, and the target device and the network can be ensured to maintain consistent state, so that reliable mobile communication service can be provided.

As shown in fig. 2, the method specifically comprises the following steps:
s201, acquiring a tracking area code currently registered by each terminal device in a current cell;
s202, identifying whether the tracking area code of the current terminal equipment is in a tracking area code list of the current cell;
s203, determining the terminal equipment of which the tracking area code is not in the tracking area code list as target equipment;
s204, acquiring the position information of each target device;
the location information may refer to latitude and longitude coordinates of the target device. A GPS (Global Positioning System ) receiver arranged in the target equipment receives signals sent by a plurality of GPS satellites, the time T for sending the signals is arranged in each signal, and then the distance from the target equipment to each GPS satellite is calculated according to the difference between the time T and the received time, so that the position information of the target equipment is obtained.
The target devices send the position information through the satellite link, and the position information of each target device can be acquired by receiving the position information sent by each target device.
S205, determining the signal intensity of the target equipment according to the position information;
the signal strength may be a physical quantity that describes the degree of strength of a signal, and may be in decibel milliwatts (dBm). In this embodiment, the signal strength of the target device refers to the signal emission strength of the satellite transmitting the satellite signal to the target device.
According to the position information of the target equipment and the position information of the satellite corresponding to the current cell, the distance between the target equipment and the satellite corresponding to the current cell can be calculated, and according to the signal receiving intensity of the target equipment and the distance, the signal sending intensity of the satellite signal can be calculated.
S206, determining unicast power according to the signal intensity;
unicast power may refer to the operating power of a communication antenna of a satellite, which may be in watts (W). A satellite's communications antenna is a device that may be used to transmit satellite signals.
The unicast power may be calculated from the signal strength and the hardware parameters of the communication antenna.
S207, unicast the tracking area code list of the current cell to the target equipment based on the unicast power.
And adjusting the working power of the communication antenna according to the unicast power, and sending the tracking area code list to the target equipment through the satellite link.
The advantage of this arrangement of the scheme is that by determining the unicast power according to the location information of the target device, it can be ensured that the target device can receive the unicast signal.
In this technical solution, optionally, before unicast the tracking area code list of the current cell to the target device based on the unicast power, the method further includes:
acquiring communication quality information of each target device, and determining unicast priority of each target device according to the communication quality information;
accordingly, unicast the tracking area code list of the current cell to the target device based on the unicast power includes:
unicast the tracking area code list of the current cell to the target device based on the unicast power and the unicast priority.
The communication quality information may refer to the signal reception strength of the target device. The signal receiving strength of the target device can be sent by the target device through a satellite link, and the communication quality information of each target device can be obtained by receiving the data sent by each target device.
Unicast priority may refer to the unicast order of the target device, it being understood that the higher the unicast priority, the earlier the unicast order of the target device. And sequencing the target devices according to the communication quality information of the target devices from high to low, and determining the unicast priority of the target devices from high to low according to the sequence.
The following is an example code for ordering target devices according to their communication quality information and determining their unicast priorities:
def sort_devices_by_priority(devices, quality_info):
# create a tuple list containing device index and communication quality information
device_info = [(index, quality_info[device]) for index, device in enumerate(devices)]
Ranking devices from high to low according to communication quality information #
sorted_devices = sorted(device_info, key=lambda x: x[1], reverse=True)
# obtain ordered device index list
sorted_indices = [device[0] for device in sorted_devices]
# determining unicast priority from ordered device index list
priority = {device: index for index, device in enumerate(sorted_indices)}
return priority
Target device list
devices = ["Device A", "Device B", "Device C", "Device D"]
Communication quality information of # target device
quality_info = {
"Device A": 8,
"Device B": 6,
"Device C": 9,
"Device D": 7
}
# ordering devices according to communication quality information, determining unicast priority
priority = sort_devices_by_priority(devices, quality_info)
Unicast priority of# output device
for device in priority:
print(f"{device}: Priority {priority[device]}")
In the above example, the 'source_devices_by_priority' function accepts two parameters: the 'devices' is a target device list, and the 'quality_info' is communication quality information of the target device, wherein the device name corresponds to the corresponding communication quality information. The function first stores the device and communication quality information as a tuple list 'device_info', and then orders the devices from high to low according to the communication quality information. The ordered device index list 'requested_indices' determines the unicast priority of the device, and the device is associated with its corresponding unicast priority using dictionary 'priority'. Finally, by iterating the unicast priorities of the output devices, the devices allocate the unicast priorities according to the order of the communication quality information from high to low.
Based on the unicast power and the unicast priority, the tracking area code list of the current cell is unicast to the target device, which can be sent in batches from high to low according to the unicast priority, and the working power of the communication antenna is adjusted according to the unicast power before each sending.
The method and the device have the advantages that the corresponding unicast priority is determined according to the communication quality information of the target equipment, and the tracking area code list is unicast according to the unicast priority, so that the communication resources can be utilized more effectively, the performance and the efficiency of the whole communication network are improved, and the instantaneity of the unicast tracking area code list is ensured.
Example III

The cell information may refer to information about NTN cells, and may include coverage and moving speed. Coverage may refer to a geographical area where NTN cells can provide communication services, and movement speed may refer to a movement distance of NTN cells from the earth's surface per unit time.
The cell information is typically stored in the NTN management platform and can be directly read.
It can be understood that the larger the coverage area and/or the faster the moving speed, the higher the acquisition frequency of the tracking area code, i.e. the acquisition frequency of the tracking area code is positively correlated with the coverage area and/or the moving speed, and a specific positive correlation function between the acquisition frequency of the tracking area code and the coverage area and/or the moving speed can be obtained based on historical data analysis, and the coverage area and/or the moving speed is substituted into the positive correlation function, so that the acquisition frequency of the tracking area code can be calculated.
The benefit of this arrangement of the scheme is that by determining the acquisition frequency of the tracking area code of each terminal device in the current cell according to the coverage area and/or the moving speed, the communication connection requirements of the terminal devices and the network load and performance can be balanced.
