[0002] In order to break through geographical restrictions, satellite Internet and ground mobile communication networks are fully integrated into a unified "network". Building a satellite-ground integrated network that covers the entire earth has become a hot topic in academic research at this stage and is also a trend in the development of the future communications field.

[0003] The satellite-ground integrated network integrates processing, switching, network control and other functions on the satellite, enriching the single forwarding function of the previous satellite network and improving the system's anti-destruction capability. In addition, the satellite-ground integrated network integrates the advantages of both satellite communication and ground network communication, not only providing users with low-latency, long-distance, and high-bandwidth communication services, but also being independent of the geographical environment and natural disasters, covering areas that ground networks cannot reach, and meeting different business needs.

[0004] In the scenario of integrated space-ground communication network, when the satellite system and the ground mobile network system use the same standard for communication, serious co-frequency interference will occur. That is, due to the sharing of satellite-ground frequency, interference will occur in subsequent data transmission.

[0059] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0060] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0061] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0062] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0063] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0064] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0065] As mentioned above, if the satellite network system and the ground mobile network system use the same standard for communication, especially the same related parameters (such as frequency, modulation method, etc.), there will be a problem of co-frequency interference. That is, due to the sharing of satellite and ground frequencies, interference will occur during subsequent data transmission.

[0066] For example, for a low-orbit satellite (such as a satellite with an altitude and speed of 600km and 7.56km / s respectively), the dwell time of a single cell is 6.61s, but the ground system transmission process is at the ms (millisecond) level, such as the paging cycle is generally 20ms. In this case, once co-channel interference occurs, the user will not be able to achieve the specified service quality communication for about 6s.

[0067] For example, co-channel interference mainly manifests itself in complex interference between satellite-to-ground communications and ground-to-ground communications, such as interference between satellites and ground user terminals, and interference between ground network base stations and satellite relay base stations.

[0068] Although spectrum sharing between satellites and the ground can improve the utilization efficiency of spectrum resources, the co-channel interference phenomenon will lead to erroneous data transmission and affect the communication quality. It is a technical issue that cannot be ignored in the study of satellite-ground integrated networks.

[0069] In order to avoid co-channel interference, the ground network can adopt the networking mode of cellular mobile communication network, which has the characteristics of frequency reuse, reduction of co-channel interference and improvement of system capacity.

[0070] Regarding co-channel interference in the space-ground integrated scenario, 3GPP or the academic community is more concerned about how to use wireless technology to achieve the best effect (such as reducing interference through signal processing methods such as beamforming).

[0071] This approach ignores the diversity of scenarios involving co-frequency interference in satellite-ground integrated networks. Therefore, differentiated solutions need to be designed for different coverage scenarios.

[0072] The present disclosure provides an adaptive discontinuous sleep method to solve the co-frequency interference problem in the air-ground scenario. In view of the co-frequency interference problem when the satellite system and the ground mobile network system use the same standard, differentiated strategies are issued to the terminal, and parameters such as access mode and timer are expanded to perform differentiated management, so as to improve the energy saving effect of the system.

[0073] The adaptive discontinuous sleep method disclosed in the present invention achieves the effect of system energy saving by issuing different strategies to terminals in different coverage scenarios and performing differential management. For example, the technical solution disclosed in the present invention can be implemented through the following embodiments.

[0074] Figure 1 A flow chart showing some embodiments of the communication method of the present disclosure.

[0075] like Figure 1 As shown, in step 110, it is determined whether there is co-channel interference between terminals covered by both the satellite network and the terrestrial mobile network.

[0076] In some embodiments, whether the terminal has co-channel interference is determined according to the indication information sent by the network side. For example, the indication information is sent by executing the access and mobility management policy modification process.

[0077] For example, when the terminal is covered by both the satellite network and the ground mobile network corresponding to the base station, the network side (such as the AMF entity, etc.) triggers the execution of the access and mobility management policy modification process. Relevant information can be provided to the PCF entity by calling Npcf_AMPolicyControl_Update signaling. In the access and mobility management policy modification process, it is possible to add an indication message to the PCF to indicate whether there is co-channel interference.

[0078] In some embodiments, when the first communication frequency of the satellite network is the same as the second communication frequency of the cell accessed by the terminal, the indication information indicates that there is co-channel interference; when the first communication frequency is different from the second communication frequency, the indication information indicates that there is co-channel interference.

[0079] For example, the first communication frequency and the second communication frequency are acquired through interaction between the access network and the network side.

[0080] For example, the network side (such as the AMF entity, etc.) obtains the satellite information (such as satellite ephemeris information, communication frequency used by the satellite, etc.) of the satellite corresponding to the satellite network covering the terminal. The RAN (Radio Access Network) or AN (Access Network) obtains the communication frequency of the wireless network accessed by the terminal during the user terminal registration process, and obtains the communication frequency of the cell where each terminal is located and the communication frequency of the satellite through interaction with the network side (such as the AMF entity).

[0081] For example, when the communication frequency of the cell corresponding to the terrestrial mobile network is different from the communication frequency of the satellite network, it is determined that there is no co-frequency interference. In this case, the satellite network and the terrestrial mobile network operate normally without adjusting the original communication process.

[0082] For example, when the communication frequency of the cell corresponding to the terrestrial mobile network is the same as the communication frequency of the satellite network, it can be determined that co-channel interference will occur. In this case, both the satellite network and the terrestrial mobile network will be severely affected, and it is necessary to perform the access and mobility management policy modification process and add a process of sending indication information to the PCF entity. It can be determined whether there is co-channel interference first, and then the PCF entity generates the access and mobility management policy and sends it to the AMF entity.

[0083] In step 120, a communication strategy corresponding to the communication scenario is generated according to the communication scenario of the terminal, and the communication scenario is determined according to whether there is co-channel interference in the terminal and the access mode supported by the terminal.

[0084] In some embodiments, when the communication scenario is that there is co-channel interference and the supported access methods include supporting access to satellite networks and terrestrial mobile networks, the communication strategy is determined as a first communication strategy for instructing the terminal to sleep.

[0085] For example, the first communication strategy includes time information when a satellite corresponding to the satellite network leaves a cell corresponding to the ground mobile network, which is used to indicate the time for the terminal to sleep.

[0086] For example, for a terminal with multiple access modes (satellite network + terrestrial mobile network), when the communication frequency of the cell of the terrestrial mobile network accessed by the terminal is the same as the communication frequency of the satellite network, the policy sent down includes the sleep timer parameter.

[0087] For example, the countdown to the satellite leaving the cell is informed to the terminal through the sleep timer parameter.

[0088] For example, the first communication strategy is used to instruct the terminal to enter a silent state until the satellite leaves the cell corresponding to the ground mobile network.

[0089] For example, when the terminal receives the mobility access policy (ie the above communication policy), if the terminal includes a sleep timer parameter including a timer, it immediately enters the silent state to achieve the technical effect of energy saving.

[0090] In some embodiments, when the communication scenario is that there is no co-channel interference and the supported access methods include supporting access to satellite networks and terrestrial mobile networks, the communication strategy is determined to be a second communication strategy including an access mode through a satellite network and an access mode through a terrestrial mobile network.

[0091] For example, for a terminal with multiple access methods (satellite network + terrestrial mobile network), when the communication frequency of the cell of the terrestrial mobile network accessed by the terminal is different from the communication frequency of the satellite network, the issued strategy includes two access modes: both satellite access and terrestrial mobile network access.

[0092] In step 130, the corresponding communication strategy is sent to the terminal.

[0093] In some embodiments, the corresponding communication policy is sent to the terminal through the AMF entity. For example, the PCF entity uses the Npcf_AMPolicyControl_Update response to update the access and mobility management related policy information to the AMF entity.

[0094] For example, the AMF entity deploys policy information related to access and mobility. The AMF entity sends differentiated communication strategies to the terminal. For multi-access terminals without co-channel interference, a communication strategy containing two access modes is sent; for terminals affected by co-channel interference, a communication strategy containing sleep timer parameters is sent. The terminal executes the communication strategy sent by the AMF entity. When the communication strategy contains sleep parameters including timers, it immediately enters the silent state to achieve energy saving.

[0095] Figure 2 A schematic diagram showing an interference pattern in a network in an air-ground-integrated scenario of the present disclosure.

[0096] like Figure 2 As shown, in the scenario of an integrated air-ground-space communication network, when the satellite system and the ground mobile network system use the same standard to communicate, serious co-channel interference will be caused, that is, interference in subsequent data transmission due to the sharing of satellite-ground frequencies.

[0097] In densely populated areas, indirect access to satellites or direct access to satellites can be used. User terminals establish connections with satellites through satellite bottom relay base stations or directly, and are also connected to ground mobile networks to participate in ground mobile communications.

[0098] In this case, satellite communication and terrestrial communication interfere with each other, for example, it can be manifested as interference between satellites and terrestrial mobile users, and interference between terrestrial network base stations and terrestrial mobile users or between satellite relay base stations.

[0099] In areas where ground base stations are difficult to establish, such as sparsely populated remote areas, oceans, and deserts, it is difficult for terminals to communicate with the outside world through ground mobile networks. In most cases, they can be integrated into the Internet by directly accessing the satellite system, that is, the satellite directly communicates with the user equipment, in which case the co-channel interference problem is less severe.

[0100] When satellite Internet and ground mobile networks are integrated into a unified network through the same standard, co-frequency interference will occur. The high-speed movement of low-orbit satellites leads to complex and variable interference between the satellite and the ground. In addition, the coverage range of a single beam of a low-orbit satellite can reach tens to hundreds of kilometers, which has a wide range of impact.

[0101] In the above embodiments, in order to solve the technical problem of co-channel interference between satellite networks and ground mobile networks, differentiated communication strategies are developed for terminals corresponding to communication scenarios, so that terminals with co-channel interference can achieve discontinuous sleep, thereby minimizing co-channel interference and energy consumption of satellite-ground systems.

[0102] Figure 3a A signaling diagram illustrating some embodiments of the communication method of the present disclosure.

[0103] like Figure 3a As shown, in event 310a, the network side (such as the AMF entity) obtains satellite information, such as satellite ephemeris information, the frequency being used by the satellite, etc.

[0104] In event 320a, RAN or An obtains the communication frequency of the terminal accessing the wireless network during the user terminal registration process; after interacting with the network side (such as the AMF entity), the frequency of the cell where each terminal is located and the frequency of satellite communication are obtained.

[0105] For example, if the cell frequency is different from the satellite communication frequency, it is determined that there is no co-frequency interference, the satellite network and the ground mobile network operate normally, and the original communication process is not adjusted. If the frequencies are the same, it is determined that there is co-frequency interference, and both satellite and ground communications will be severely affected.

[0106] In event 330a, when the terminal has both satellite coverage and base station coverage, the access and mobility management policy modification process is triggered. Relevant information is provided to the PCF entity by calling Npcf_AMPolicyControl_Update signaling, in which an indication information is newly sent to the PCF, that is, whether there is co-channel interference.

[0107] In event 340a, the PCF entity issues different policies to terminals in different cells.

[0108] For example, for terminals with multiple access methods (satellite + terrestrial mobile network): if the frequency of the terminal accessing the cell is different from the satellite communication frequency, the policy sent down includes two access modes (both satellite access and terrestrial mobile network access); if the frequency of the terminal accessing the cell is the same as the satellite communication frequency, the policy sent down includes the sleep timer parameters, which inform the terminal through the timer of the countdown for the satellite to leave the cell.

[0109] In event 350a, the PCF entity uses the Npcf_AMPolicyControl_Update response to update the access and mobility management related policy information to the AMF entity.

[0110] In event 360a, the AMF entity deploys policy information related to access and mobility.

[0111] In event 370a, the AMF entity sends differentiated policies to the terminal. For multi-access terminals without co-channel interference, a policy containing two access modes is sent; for terminals affected by co-channel interference, a policy containing sleep timer parameters is sent.

[0112] In event 380a, the terminal executes the policy issued by the AMF entity in event 370a, and immediately enters the silent state when the sleep parameters including the timer are included, thereby achieving energy saving.

[0113] In the above embodiment, in the scenario of an integrated space-ground communication network, when the satellite system and the ground mobile network system use the same standard for communication, serious co-channel interference will be caused. That is, interference in subsequent data transmission due to satellite-ground frequency sharing. By issuing differentiated strategies to the terminal, the terminal with co-channel interference can achieve discontinuous sleep, thereby minimizing co-channel interference and satellite-ground system energy consumption.

[0114] In the above embodiment, when the terminal has both satellite coverage and base station coverage, the access and mobility management policy modification process is triggered, in which an indication information is newly sent to the PCF entity, that is, whether there is co-channel interference.

[0115] There are differences in the strategies issued to terminals in different cells. For terminals with multiple access modes (satellite + terrestrial mobile network), if the frequency of the terminal accessing the cell is different from the satellite communication frequency, the strategy issued includes two access modes (both satellite access and terrestrial mobile network access); if the frequency of the terminal accessing the cell is the same as the satellite communication frequency, the strategy issued includes the sleep timer parameter, which informs the terminal of the countdown for the satellite to leave the cell through the timer.

[0116] When the user terminal receives the mobility access policy, if the policy contains sleep parameters including a timer, it immediately enters the silent state to achieve energy saving.

[0117] Figure 3b Flowcharts showing other embodiments of the communication method of the present disclosure.

[0118] like Figure 3b As shown, in step 310b, it is determined whether there is co-channel interference between the terminals covered by both the satellite network and the terrestrial mobile network.

[0119] In step 320b, the determination result is sent to the PCF entity via indication information.

[0120] In step 330b, a communication policy corresponding to the communication scenario of the terminal returned by the PCF entity is received, and the communication scenario is determined according to the judgment result and the access mode supported by the terminal.

[0121] In step 340b, the corresponding communication strategy is sent to the terminal.

[0122] In some embodiments, when the communication scenario is that there is co-channel interference and the supported access methods include supporting access to satellite networks and terrestrial mobile networks, the corresponding communication strategy includes a first communication strategy for instructing the terminal to sleep.

[0123] In some embodiments, the first communication strategy includes time information when a satellite corresponding to the satellite network leaves a cell corresponding to the ground mobile network, which is used to indicate the time for the terminal to sleep.

[0124] In some embodiments, the first communication strategy is used to instruct the terminal to enter a silent state until the satellite leaves the cell corresponding to the terrestrial mobile network.

[0125] In some embodiments, when the communication scenario is that there is no co-channel interference and the supported access methods include supporting access to satellite networks and terrestrial mobile networks, the communication strategy is a second communication strategy that includes an access mode through a satellite network and an access mode through a terrestrial mobile network.

[0126] In some embodiments, when the first communication frequency of the satellite network is the same as the second communication frequency of the cell accessed by the terminal, the judgment result is determined as the existence of co-channel interference; when the first communication frequency is different from the second communication frequency, the judgment result is determined as the existence of co-channel interference.

[0127] In some embodiments, the first communication frequency and the second communication frequency are acquired by interacting with an access network.

[0128] In some embodiments, the determination result is sent by executing an access and mobility management policy modification process.
