Detailed Description
In this embodiment, an application scenario of the access method of the user terminal in the heaven-earth integrated information network is shown in fig. 1. In fig. 1, the core network may be a core network of a 4G network or a 5G network, which includes NWDAF network elements and other components. The core network is connected with the ground base station and the satellite signal ground receiving station through connecting media such as optical fibers, and the core network is connected with the communication satellite through the satellite signal ground receiving station. The user terminal may be a mobile phone or tablet computer or other terminal held by a personal user, or may be a communication terminal installed in a vehicle, a ship or an airplane. The user terminal can be connected with the core network through a communication satellite so as to access a 4G or 5G communication network; the user terminal can also be connected with the core network through the ground base station so as to access the 4G or 5G communication network.
In this embodiment, as shown in fig. 2, the method for accessing a user terminal in a heaven-earth integrated information network includes the following steps:
s1, detecting a current access mode of a first user terminal to a core network; the current access mode is one of the following: accessing through a communication satellite and accessing through a ground base station;
s2, acquiring first connection information generated by a first user terminal in a core network;
s3, detecting a matching relation between the first connection information and the current access mode;
s4, when the first connection information is matched with the current access mode, indicating or controlling the first user terminal to maintain the current access mode to access the core network, and otherwise, indicating or controlling the first user terminal to switch to access the core network in a new access mode; the new access mode is one of the following modes: accessing through a communication satellite and accessing through a ground base station; the new access mode is different from the current access mode.
In this embodiment, the steps S1-S4 may be performed by the core network, and specifically, the steps S1-S4 may be performed by an NWDAF network element in the core network.
In this embodiment, the core network is connected to a plurality of user terminals, the user terminals are connected to the core network through the ground base station or the communication satellite, and each user terminal may autonomously select or select to be connected to the core network through the ground base station or the communication satellite under control. The steps S1-S4 will be explained for one of the user terminals connected to the core network, i.e., the first user terminal.
In step S1, the NWDAF network element detects a current access mode of the first user terminal to the core network. In this embodiment, the first user terminal may be connected to the core network through the ground base station or through the communication satellite, and at the time of executing step S1, the current access mode of the first user terminal is one of accessing to the core network through the communication satellite and accessing to the core network through the ground base station. For example, if the first user terminal accesses the core network through the communication satellite while the step S1 is performed and for a while before the step S1 is performed, the current access manner of the first user terminal is to access through the communication satellite.
In step S2, the NWDAF network element acquires first connection information generated by the first user terminal in the core network. In this embodiment, the first connection information may refer to request information and related handshake information sent to the core network when the first user terminal requests to access the core network, or log record type information generated in a process of performing a communication service after the first user terminal accesses the core network.
In step S2, the access of the first user terminal to the core network may be "initial access" or "access for a period of time", where the "initial access" may mean that the first user terminal has never accessed the core network before, the first user terminal has just accessed the core network when step S2 is performed, or the first user terminal has accessed the core network before, has accessed the core network after a period of disconnection, and the first user terminal has just accessed the core network when step S2 is performed. In this embodiment, the situation that the access of the first user terminal to the core network belongs to the "initial access" or the "access for a certain time" may be determined by detecting the traffic generated when the first user terminal connects to the core network.
The NWDAF network element may detect a traffic volume generated when the first user terminal connects to the core network, and specifically, the traffic volume may refer to parameters such as a data traffic cumulative value, a data traffic rate, or a continuous connection duration, and set a corresponding data traffic cumulative value threshold, a data traffic rate threshold, or a continuous connection duration threshold as a traffic volume threshold. If the traffic generated by the first user terminal connecting to the core network reaches the traffic threshold, for example, the data traffic integrated value generated by the first user terminal connecting to the core network is greater than the data traffic integrated value threshold, the data traffic rate generated by the first user terminal connecting to the core network is greater than the data traffic rate threshold, or the continuous connection duration generated by the first user terminal connecting to the core network is greater than the continuous connection duration threshold, it can be determined with confidence that the access of the first user terminal to the core network belongs to the situation of "accessed for a period of time"; if the traffic generated by the first user terminal connecting to the core network does not reach the traffic threshold, for example, the data traffic integrated value generated by the first user terminal connecting to the core network is smaller than the data traffic integrated value threshold, the data traffic rate generated by the first user terminal connecting to the core network is smaller than the data traffic rate threshold, or the continuous connection duration generated by the first user terminal connecting to the core network is smaller than the continuous connection duration threshold, it can be determined with confidence that the access of the first user terminal to the core network belongs to the "initial access" condition.
If the traffic does not reach the traffic threshold, i.e. the access of the first user terminal to the core network belongs to the "initial access", then referring to fig. 3, the NWDAF may obtain the user identification information and the behavior record information of the first user terminal as the first connection information. The user identification information may include information such as terminal identification information and access support type information, and the behavior record information may include information such as silent duration information, traffic reporting frequency information, and location updating frequency information.
Specifically, when the first user terminal transmits the first connection information to the NWDAF, referring to fig. 4, in the first four bits of the Protection scheme id field, information such as an indication of supporting the core network selective access method, access type information supported by the user terminal, and terminal identification information may be inserted into the 5GS mobile identity field of the registration request message transmitted to the NWDAF. The user terminal supports access type information including ground base station access or communication satellite access; the terminal identification information indicates the type of the user terminal, and the user terminal type includes but is not limited to a user equipment such as a mobile phone, a CPE, and the like.
If the traffic volume reaches the preset traffic volume threshold, that is, the access of the first user terminal to the core network belongs to the condition of "having been accessed for a period of time", referring to fig. 5, the NWDAF acquires the service information of the first user terminal generated in the core network as the first connection information, where the service information includes subscription information, location information, traffic information, voice information, video information, and other information.
In this embodiment, by executing step S2, the first connection information can be obtained, and is used for the NWDAF network element to execute step S3, so as to determine whether the first connection information matches the current access mode. Under the condition that the access of the first user terminal to the core network belongs to 'initial access', the first connection information comprises user identification information and behavior record information such as terminal identification information, access supporting type information, silence duration information, traffic reporting frequency information and position updating frequency information, and under the condition that the access of the first user terminal to the core network belongs to 'accessed for a period of time', the first connection information comprises service information such as subscription information, position information, traffic information, voice information and video information, so that under the condition of 'initial access' or 'accessed for a period of time', the first connection information comprises information capable of reflecting the service requirement of the first user terminal.
Intuitively speaking, the NWDAF network element executes step S3, and may analyze the service requirement of the first user terminal through the first connection information, and if the current access mode matches the first connection information, it indicates that the current access mode of the first user terminal can meet the service requirement of the first user terminal; and if the current access mode is not matched with the first connection information, the current access mode of the first user terminal is indicated to be incapable of meeting the service requirement of the first user terminal.
In this embodiment, when the NWDAF performs step S3, that is, the step of detecting the matching relationship between the first connection information and the current access mode, the following steps may be specifically performed:
S301A, setting standard connection information;
S302A, detecting similarity between the first connection information and the standard connection information;
and S303A, when the similarity between the first connection information and the standard connection information reaches a similarity threshold, determining that the first connection information and the current access mode meet the matching condition, and otherwise, determining that the first connection information and the current access mode do not meet the matching condition.
The NWDAF may set information as shown in table 1 or table 2 as the sets of standard connection information when performing step S301A.
TABLE 1
| Numbering | Current access mode | Terminal type | User behavior |
| 1 | Ground base station | Mobile phone | Multiple traffic reporting per unit time |
| 2 | Ground base station | Mobile phone | Multiple location updates per unit time |
| 3 | Communication satellite | Aircraft with a flight control device | Multiple traffic reporting per unit time |
| ... | ... | ... | ... |
TABLE 2
In this embodiment, when step S302A is executed, for the case that the access of the first user terminal to the core network belongs to "initial access", the similarity may be calculated by using a set of standard connection information and the first connection information shown in table 1. Specifically, each row shown in table 1 may be regarded as a set of standard connection information, and each set of standard connection information may be further regarded as a vector such as (terrestrial base station, mobile handset, reporting traffic multiple times per unit time) and (terrestrial base station, mobile handset, updating location multiple times per unit time), that is, the standard connection information shown in each row in table 1 may be vectorized. Then, from user identification information and behavior record information, such as terminal identification information, access support type information, silent duration information, traffic reporting frequency information, location updating frequency information, and the like, included in the first connection information, such as a current access mode, a terminal type, a user behavior, and the like, is sorted out and expressed as a vector, and then, using algorithms, such as a manhattan distance, an euclidean distance, or a chebyshev distance, and the like, a distance between the vector expressed by the first connection information and a set of standard connection information shown in table 1 is calculated as a similarity.
Similarly, for the case that the access of the first user terminal to the core network belongs to "accessed for a period of time", the similarity may be calculated using the set of standard connection information and the first connection information shown in table 2. Similarly, each row shown in table 2 can be regarded as a set of standard connection information, and further each set of standard connection information can be regarded as vectors like (communication satellite, short message service, voice information) and (terrestrial base station, large traffic service, video information), that is, each row shown in table 2 can be vectorized. Then, information such as a current access mode, a subscription service, a data type, and the like is sorted out from service information such as subscription information, location information, traffic information, voice information, video information, and the like included in the first connection information, and expressed as a vector, and then a distance between the vector expressed by the first connection information and a set of standard connection information shown in table 2 is calculated as a similarity using an algorithm such as a manhattan distance, an euclidean distance, or a chebyshev distance.
In this embodiment, when step S301A is executed, appropriate standard connection information may be selected according to the current access mode. For example, in the case that the access of the first user terminal to the core network belongs to "accessed for a period of time", if the current access mode is access through a communication satellite, it is appropriate to carry a short message service containing voice information, and the standard connection information may be set to the information shown in the first row in table 2; if the current access mode is via the ground base station, then it is appropriate to carry a large traffic flow containing video information, and the standard connection information can be set as the information shown in the second row in table 2.
In this embodiment, the information shown in table 1 and table 2 is only an example, and on this basis, standard connection information with a higher dimension may be set, and the first connection information with the corresponding dimension may be required to be acquired.
In step S303A, if the similarity between the first connection information and the standard connection information reaches the similarity threshold, according to the principle of setting the standard connection information when step S301A is executed, the service and the access condition reflected by the standard connection information are matched with the current access mode, and the first connection information is similar to the standard connection information enough to ensure that the service and the access condition reflected by the first connection information are also matched with the current access mode; similarly, if the similarity between the first connection information and the standard connection information does not reach the similarity threshold, the service and the access condition reflected by the first connection information may be considered as being unmatched with the current access mode.
After step S303A is performed, step S4 may be performed. When the similarity between the first connection information and the standard connection information reaches a similarity threshold value, that is, the first connection information is matched with the current access mode, the service and the access condition reflected by the first connection information can be considered to be matched with the current access mode with enough confidence, that is, the current access mode can meet the service requirement of the first user terminal, and the core network can indicate or control the first user terminal to maintain the continuous access to the core network in the current access mode; when the similarity between the first connection information and the standard connection information does not reach the similarity threshold, that is, the current access mode is not matched with the first connection information, it may be sufficient to grasp that the service reflected by the first connection information and the access condition are not matched with the current access mode, that is, the current access mode cannot meet the service requirement of the first user terminal, the core network may instruct or control the first user terminal to switch to access the core network in a new access mode, for example, if the current access mode is access through a communication satellite, the new access mode is access through a ground base station, and if the current access mode is access through a ground base station, the new access mode is access through a communication satellite.
In this embodiment, when the NWDAF performs step S3, that is, the step of detecting the matching relationship between the first connection information and the current access mode, the following steps may be further specifically performed:
S301B, detecting a plurality of user terminals connected with a core network;
S302B, setting the second user terminal as a search target, and searching in a plurality of user terminals connected with the core network according to the first connection information; the connection maintaining time length between the second user terminal and the core network exceeds a time length threshold value, and the access mode of the second user terminal to the core network is different from the current access mode; the second user terminal generates second connection information in the core network, and the similarity between the second connection information and the first connection information reaches a similarity threshold;
and S303B, when the second user terminal is searched, confirming that the first connection information and the current access mode do not meet the matching condition, and otherwise, confirming that the first connection information and the current access mode meet the matching condition.
In step S301B, the core network may detect all the user terminals connected to the core network.
In step S302B, the core network searches whether there is a second user terminal that satisfies a specific condition among all the user terminals connected to the core network.
Wherein, the specific conditions to be satisfied by the second user terminal include:
(1) the connection maintaining time length between the second user terminal and the core network exceeds a time length threshold value, namely the second user terminal is not just accessed to the core network, which indicates that the second user terminal maintains the access mode to the core network for a long time and is sure to think that the access mode of the second user terminal can meet the service requirement of the second user terminal;
(2) the second user terminal generates second connection information in the core network, and the similarity between the second connection information and the first connection information reaches a similarity threshold; the principle of step S302A may be referred to, that the second connection information and the first connection information are represented as vectors with the same dimension, and then the similarity between the second connection information and the first connection information is calculated through a vector similarity or association calculation algorithm; under the condition that the similarity between the second connection information and the first connection information reaches a similarity threshold, the service performed by the second user terminal through the core network can be considered to be similar to the service performed by the first user terminal through the core network;
(3) the access mode of the second user terminal to the core network is different from the current access mode; for example, if the current access mode of the first user terminal is through a communication satellite, the access mode of the second user terminal to the core network is required to be through a ground base station, and if the current access mode of the first user terminal is through a ground base station, the access mode of the second user terminal to the core network is required to be through a communication satellite.
The result of performing step S302B may be that a second user terminal satisfying the condition is searched, or that no second user terminal is searched.
Step S303B is executed, when a second user terminal meeting the condition is searched, since the second user terminal meets the conditions (1) - (3), which indicates that the access mode of the second user terminal can meet the service requirement of the second user terminal, and the service of the second user terminal is similar to the service of the first user terminal, it is sure that if the current access mode of the first user terminal is switched to be consistent with the access mode of the second user terminal, the service requirement of the first user terminal can also be met by the access mode, so that it can be confirmed that when the first connection information and the current access mode do not meet the matching condition, the core network indicates or controls the first user terminal to switch to access the core network in a new access mode; in the case that the second user terminal which does not satisfy the condition is not searched, it is not sure that if the access mode of the first user terminal is switched, the service requirement of the first user terminal can also be satisfied by the new access mode.
In this embodiment, by detecting a matching relationship between first connection information of a first user terminal and a current access mode, when the first connection information matches the current access mode, the first user terminal maintains accessing the core network in the current access mode, and when the first connection information does not match the current access mode, the first user terminal switches to accessing the core network in a new access mode, and since a service requirement of the first user terminal can be obtained through analysis of the first connection information, the access method of the user terminal in this embodiment can automatically control the access mode of the first user terminal to the core network, and enable the access mode of the first user terminal to the core network to meet the service requirement of the first user terminal, for example, to achieve matching states such as "access to carry video service through a ground base station", "access to carry short message service in the field through a communication satellite", thereby obtaining good communication quality and stability.
In this embodiment, a core network, a communication satellite and a ground base station may be used to form a space-ground integrated information network, where the communication satellite and the ground base station are respectively connected to the core network, and the communication satellite and the ground base station are respectively used for the first user terminal to connect to access the core network. The core network can execute the access method of the user terminal in this embodiment, so that the heaven and earth integrated information network can achieve the technical effects of obtaining good communication quality and stability and the like of the access method of the user terminal in this embodiment.
The same technical effects as those of the access method of the user terminal in the space-and-ground integrated information network in the embodiment can be achieved by writing a computer program for executing the access method of the user terminal in the space-and-ground integrated information network in the embodiment, writing the computer program into a computer device or a storage medium, and executing the access method of the user terminal in the space-and-ground integrated information network in the embodiment when the computer program is read out and run.
