Detailed Description
In this embodiment, an application scenario of the heaven-earth integrated information network is shown in fig. 1. Referring to fig. 1, on the ground, a base station is connected to a core network, and a user uses a user terminal, where the user terminal may be a mobile phone, a tablet computer, or a special instrument. And communication satellites on different orbits such as a high orbit satellite GEO, an intermediate orbit satellite MEO, a low orbit satellite LEO and the like are operated in the space, wherein the height of the operation orbit of the GEO is greater than that of the MEO, and the height of the operation orbit of the MEO is greater than that of the LEO. The user terminal may communicate with the base station either directly, thereby connecting directly to the core network, or via a communications satellite, thereby connecting to the core network.
In this embodiment, the first satellite and the second satellite are a pair of communication satellites operating in orbits of different heights, where the first satellite operates in a first satellite orbit, the second satellite operates in a second satellite orbit, and the height of the first satellite orbit is smaller than the height of the second satellite orbit, that is, the height of the second satellite orbit is larger than the height of the first satellite orbit, and the first satellite is closer to the ground than the second satellite. It is desirable that the first satellite is one of the LEOs, the second satellite is one of the MEOs, the first satellite is one of the LEOs, the second satellite is one of the GEO, the first satellite is one of the MEOs, the second satellite is one of the GEO, and so on. Since the communication delay between the user terminal and the LEO is relatively low compared to the MEO and the GEO, the embodiment will be described by taking the example that the first satellite is one of the LEO and the second satellite is one of the GEO.
In this embodiment, the heaven and earth integrated information network includes a broadcasting unit, a first UDM network element, an AMF network element, and other units. When the heaven-earth integrated information network is operated, the broadcasting unit is installed on the second satellite, and the first UDM network element and the AMF network element are installed on the first satellite. In this embodiment, the UDM network element and the AMF network element in the ground core network may be migrated to a first satellite, the UDM network element and the AMF network element in the ground core network are not retained in the ground core network, the UDM network element and the AMF network element may also be retained in the ground core network, and a set of UDM network element and an AMF network element is additionally arranged on the first satellite.
In this embodiment, the first satellite and the second satellite may also be part of a space-ground integrated information network, and the space-ground integrated information network may further include other LEO, MEO, and GEO that operate in orbit.
In this embodiment, when the user terminal needs to request access to the integrated information network, the user terminal may directly send registration request information to the second satellite. After the second satellite receives the registration request information, the broadcast unit processes the registration request information, and the broadcast unit broadcasts the registration request information to the outside. Specifically, when the broadcasting unit broadcasts the registration request information, the signal transmission target direction may be set to an orbit lower than the orbit of the second satellite, for example, in this embodiment, the second satellite is one of GEO, and the signal transmission target direction of the broadcasting unit may be the orbit of MEO, LEO, and the like, so that the signal transmission efficiency may be improved and the power consumption may be reduced.
In this embodiment, the base station may also be a part of a world-wide integrated information network, and the base station may be a gbb of the 5G standard. The user terminal can send the registration request information to the base station firstly, and then the base station sends the registration request information to the second satellite, so that the high transmitting power advantage of the base station can be utilized, the transmitting power requirement on the user terminal is reduced, and the power consumption of the user terminal is reduced. Specifically, when the user terminal UE sends registration Request information to the base station gNB, the user terminal establishes RRC connection with the base station, the user terminal initiates a registration Request information Register Request of the type InitialRegistration, and the registration Request information Register Request carries information such as SUPI, NSSAI, security parameters, NAS information of the user terminal UE, location information of the base station gNB itself, and N2 interface parameters such as Cell ID. The base station transmits a registration Request information Register Request to the second satellite. After receiving the registration Request information Register Request of the user terminal UE, the base station gNB determines a specific first satellite according to NSSAI provided by the user terminal UE or selects a corresponding AMF according to configuration, and the AMF installed in the first satellite provides access service for the user terminal.
The second satellite broadcasts the registration request information to the outside after receiving the registration request information, and the first satellite can directly receive the registration request information broadcasted by the second satellite. If the distance between the orbit of the first satellite and the orbit of the second satellite is long, for example, the second satellite is GEO and the first satellite is LEO, the first satellite and the second satellite are separated by MEO orbit, a relay manner can be adopted, firstly, an MEO receives the registration request information broadcasted by the second satellite, then, the MEO broadcasts the registration request information again, and the first satellite receives the registration request information broadcasted by the MEO.
After the first satellite receives the registration request information, the first UDM network element installed on the first satellite processes the registration request information. Specifically, the first UDM network element may be a network element having a complete UDM function in the 5G communication standard, or may be a network element having only an access mobility management related data subscription function in the 5G communication standard. And the first satellite is also provided with an AUSF network element, the first UDM network element is matched with the AUSF network element, authentication and verification are carried out on the user equipment according to the registration request information, authentication and verification result information is obtained, and the specific value of the authentication and verification result information comprises passing authentication or failing authentication.
And the AMF network element acquires authentication result information from the AUSF network element, accepts the registration of the user equipment if the authentication result information is passed, and refuses the registration of the user equipment if the authentication result information is not passed. If the AMF network element accepts the user equipment registration, the user equipment registration is successful, and if the AMF network element refuses the user equipment registration, the user equipment registration is failed.
And the AMF network element generates registration result information, wherein the specific value of the registration result information comprises registration success or registration failure. And the AMF network element returns the registration result information to the base station through the signal transmitting equipment in the first satellite. The base station may further return registration result information to the user equipment to notify the user equipment of the registration result.
In this embodiment, the ground core network may also be a part of a world-wide integrated information network. The base station may send the registration result information to a second UDM network element in the ground core network. Specifically, the second UDM network element may be a network element having a complete UDM function in the 5G communication standard, or may be a network element having only a session establishment function in the 5G communication standard. And if the registration result information shows that the user equipment is successfully registered, the second UDM network element establishes sessions such as PDU session and the like for the user equipment, so that a core network in the heaven-earth integrated information network and a communication satellite network of a space-based satellite can provide 5G communication service for the user equipment.
In the integrated sky-ground information network in this embodiment, the AMF network element and the UDM network element which are originally arranged on the ground are integrated or the access mobility management related data signing function of the UDM network element is arranged on the communication satellite, and the registration process does not depend on the communication between the communication satellite and the core network, so that the signaling transmission burden of the communication satellite in the registration process of the user equipment is light, and the communication delay between the communication satellite and the core network can be avoided; when the registration request information sent by the user equipment is received, the communication satellite operating in a higher orbit receives the registration request information, and then broadcasts and forwards the registration request information to the communication satellite operating in a lower orbit, so that the advantage of wide coverage of the communication satellite in the higher orbit can be utilized, the available low-orbit communication satellite can be found more easily, and the registration success rate of the user equipment is improved. The AMF network element and the UDM network element are integrated on the communication satellite capable of providing the communication service, so that the processes of searching the core network and the like in the registration process of the user equipment requesting the core network are avoided, and the saved processing time can cover the time delay increased by the user equipment sending the registration request information to the high orbit satellite.
