[0115] The present disclosure will be described in further detail below with reference to the accompanying drawings and embodiments.

[0116] Terminal network sharing refers to the use of one or more terminals as network access points to provide network access to other terminals in the same area. Due to significant differences in speed, latency, and packet loss rates between different terminals and access methods, terminal network sharing technologies, represented by terminal wireless local area network (WLAN) sharing and device-to-device (D2D) communication, have been widely adopted in both fixed and mobile networks since the fourth-generation mobile communications (4G) era. These technologies significantly improve terminal connection speeds in multi-connection scenarios and enrich the user experience. For example, they can provide in-call data services for circuit switch fall back (CSFB) terminals and enable traffic sharing among multiple users in the same area.

[0117] Related technologies have yet to propose end-to-end, systematic terminal network sharing technologies and mechanisms for fixed, mobile, and satellite converged networks. To further improve the fixed, mobile, and satellite converged technology system and provide a technical foundation for multi-connected terminal users to utilize terminal network sharing services, it is necessary to propose a fixed, mobile, and satellite converged terminal network sharing system, method, and corresponding process.

[0118] It's important to note that within a converged fixed, mobile, and satellite network, there are three types of access: fixed access, mobile access, and satellite access. Fixed access includes fixed wired access and fixed wireless access; mobile access encompasses second-generation (2G), third-generation (3G), 4G, 5G, and future 6G mobile access; and satellite access encompasses geostationary Earth orbit (GEO), medium Earth orbit (MEO), and low Earth orbit (LEO). Compared to fixed and mobile access, satellite access offers lower speeds. For example, the Tiantong-1 GEO constellation offers a maximum access speed of 384 kilobits per second (Kbps) for portable terminals, and the StarNet Phase I LEO constellation offers a maximum access speed of 2 megabits per second (Mbps) for handheld terminals. Fixed access and 5G mobile access can reach speeds of up to 1 gigabit per second (Gbps). Furthermore, satellite access typically exhibits higher latency and packet loss than fixed and mobile access. Satellite access also has characteristics such as limited communication capacity, dynamic network topology, and frequent connection switching. Therefore, terminal network sharing for fixed, mobile, and satellite convergence requires full consideration of the differences between satellite access, fixed access, and mobile access. This approach, combined with typical application scenarios for converged fixed, mobile, and satellite networks, should enhance and optimize existing terminal network sharing systems and methods.

[0119] In actual applications, if the terminal network sharing system, method, and corresponding process for fixed and mobile networks proposed in related technologies are directly applied to a fixed, mobile, and satellite converged network, the following three problems may arise:

[0120] Issue 1: The relevant technology does not consider the differences between satellite access, fixed access, and mobile access, and does not differentiate between the access methods used by terminal network sharers;

[0121] Problem 2: Related technologies do not fully consider users’ terminal network sharing needs;

[0122] Question 3: The relevant technology does not fully consider the mobility of multi-connected terminals.

[0123] Among them, for the above-mentioned question 1, in a fixed, mobile and satellite converged network, the satellite access rate is lower than that of fixed access and mobile access, and the delay and packet loss rate of satellite access are higher than those of fixed access and mobile access. If the selection of terminal network sharers does not take into account the access method currently used by the terminal, the terminal network sharing may fail or the sharing requirements may not be met.

[0124] Regarding the above-mentioned question 2, the fixed, mobile and satellite converged network has the characteristics of limited communication capacity, dynamic network topology, and frequent connection switching. If the terminal network sharing requirements such as the user's terminal network role (which may include terminal network sharer and terminal network user), access method, access requirements, sharing / usage time period, and communication method are not taken into consideration, it will be difficult to fully utilize the limited resources of the terminal network and difficult to ensure the efficiency and reliability of terminal network sharing.

[0125] Regarding question 3 above, in the fixed, mobile and satellite converged network, a variety of terminal forms are introduced, including handheld, portable, vehicle-mounted, ship-mounted and airborne multi-connected terminals. The terminals may have strong mobility and the terminal network has dynamic topology characteristics. If the real-time location information and trajectory of the multi-connected terminals are not considered, the stability and robustness of terminal network sharing may be poor.

[0126] Based on this, in various embodiments of the present disclosure, for fixed, mobile and satellite converged networks, a network function for managing and centrally controlling terminal network sharing is added to the ground-based core network and / or the space-based core network. When there is a demand for network sharing between terminals in a specific area, the function determines a terminal list for the area. The multiple terminals included in the list meet specific conditions, that is, the multiple terminals included in the list can perform network sharing between terminals in the area, and each terminal included in the list can serve as a master node, a backup master node or a slave node for network sharing between terminals. The function sends the list to each terminal included in the list, so that each terminal can perform network sharing between terminals based on the conditions. According to the list, network sharing between terminals is performed as the main node, backup main node or slave node; in this way, when the new network function for managing and centrally controlling terminal network sharing in the ground-based core network and / or the space-based core network determines the terminal list for network sharing between terminals, the differences in fixed, mobile and satellite access capabilities can be fully considered, that is, the multiple terminals included in the list can meet specific conditions, that is, the multiple terminals included in the list can perform network sharing between terminals in the area, thereby effectively reducing the probability of terminal network sharing failure and the probability of the terminal network not meeting the sharing requirements, that is, at least the above-mentioned problem 1 can be solved.

[0127] Specifically, an embodiment of the present disclosure provides a network sharing method, which is applied to the first function. As shown in FIG2 , the method includes:

[0128] Step 201: When there is a demand for network sharing between terminals in a first geographical area, a first list is determined for the first geographical area, the first list including a plurality of terminals that meet a first condition and first information of each terminal, the first condition indicating that the plurality of terminals are capable of performing network sharing between terminals in the first geographical area, the first information indicating that the terminal functions as a master node, a backup master node, or a slave node for performing network sharing between terminals, each terminal having the ability to access multiple networks, and the first function belonging to any of the multiple networks;

[0129] Step 202: Send the first list to each of the multiple terminals, so that each terminal acts as a master node, a backup master node, or a slave node to perform inter-terminal network sharing according to the first list.

[0130] When network sharing is performed between terminals, the slave node can access the corresponding network through the master node or the backup master node.

[0131] In actual application, each terminal has the ability to access multiple networks, which means that each terminal is a multi-connection terminal, and the multiple networks may include at least two networks among fixed networks, mobile networks, and satellite networks; the first function belongs to any network among the multiple networks, which means that the first function can be deployed in a ground-based core network and / or a space-based core network.

[0132] In actual applications, the terminal may also be referred to as user equipment (UE) or a user. Furthermore, it is understood that the first function is used to manage and centrally control terminal network sharing; the first function may also be referred to as a terminal network sharing management function, etc., and the first list may also be referred to as a terminal list or a multi-connected terminal list, etc. The embodiments of this disclosure do not limit the specific names of the first function and the first list, as long as their functions are implemented.

[0133] In actual application, the specific method for determining the first geographical area and the specific scope of the first geographical area can be set according to the terminal network sharing requirements, and the embodiments of this disclosure are not limited to this. For example, the first geographical area can be pre-specified on the first function; or one or more (i.e., at least two) multi-connection terminals can request the first function to share the network between terminals, and the first function can determine the first geographical area based on the location and / or trajectory of these terminals.

[0134] In actual application, when the first function receives a request for network sharing between terminals from one or more (ie, at least two) multi-connection terminals located in the first geographical area, the first function can determine that there is a demand for network sharing between terminals in the first geographical area.

[0135] Based on this, in one embodiment, the method may further include:

[0136] When at least one first request is received, it is determined that there is a demand for network sharing between terminals in the first geographical area, the first request being sent by a terminal located in the first geographical area, and the first request being used to request network sharing between terminals.

[0137] In actual application, the specific content of the first request can be set according to the terminal network sharing requirements, which is not limited in the embodiment of the present disclosure. For example, the first request can include a terminal identifier and second information, and the second information can reflect the network sharing requirements of the terminal.

[0138] In actual application, regardless of whether at least one multi-connection terminal located in the first geographical area sends the first request to the first function, these terminals can configure their own network sharing requirements to the first function in a specific process (such as an access process), and the first function can determine whether there is a network sharing requirement between terminals in the first geographical area based on the network sharing requirement configuration of these terminals.

[0139] Based on this, in one embodiment, the method may further include:

[0140] When at least one second information is received, it is determined that there is a network sharing demand between terminals in the first geographical area, and the second information is sent by a terminal located in the first geographical area, and the second information can reflect the network sharing demand of the terminal.

[0141] In one embodiment, the second information may include at least one of the following:

[0142] third information, where the third information indicates whether the terminal supports inter-terminal network sharing as a first-category terminal;

[0143] Fourth information, the fourth information indicating whether the terminal supports inter-terminal network sharing as a second-category terminal;

[0144] fifth information, where the fifth information is used to indicate a network access mode supported by the terminal when the terminal is a first-category terminal;

[0145] Sixth information, the sixth information is used to indicate a time range in which the terminal supports network sharing between terminals when the terminal is a first-category terminal;

[0146] seventh information, where the seventh information is used to indicate a QoS requirement of the terminal as a second-category terminal;

[0147] Eighth information, the eighth information is used to indicate a time range for supporting inter-terminal network sharing when the terminal is a second-category terminal;

[0148] Ninth information, the ninth information is used to indicate the communication mode supported by the terminal with other terminals.

[0149] Among them, when network sharing is performed between terminals, the second type of terminal can access the corresponding network through the first type of terminal. It can be understood that the first type of terminal is a terminal network sharer, and the second type of terminal is a terminal network user; the first type of terminal can be used as a master node or a backup master node to share the network between terminals, and the second type of terminal can be used as a slave node to share the network between terminals.

[0150] In actual application, the third information and the fourth information can be understood as the configuration of the multi-connection terminal to the terminal network sharing role (i.e., terminal network sharer, terminal network user). The specific form of the third information and the fourth information can be set according to needs and is not limited in this embodiment of the present disclosure.

[0151] In actual application, the fifth information can be used to indicate at least one network access method (i.e., one or more (i.e., at least two) network access methods) including fixed wired access, fixed wireless access, 2G mobile access, 3G mobile access, 4G mobile access, 5G mobile access, 6G mobile access, GEO satellite access, MEO satellite access, and LEO satellite access.

[0152] In actual application, the specific format of the time range indicated by the sixth information can be set according to needs; for example, the sixth information can be used to indicate that the time period for sharing the terminal network when the multi-connection terminal becomes a terminal network sharer is [20H, 24H] every day.

[0153] In actual application, the specific content of the QoS requirement indicated by the seventh information can be set according to the demand; for example, the seventh information can be used to indicate the access rate, delay and packet loss rate requirements when the multi-connection terminal becomes a terminal network user, for example, the access rate>10Mbps, the delay<100 milliseconds (ms), the packet loss rate<10 -4 .

[0154] In actual application, the specific format of the time range indicated by the eighth information can be set according to needs; for example, the eighth information can be used to indicate that the time period for using the shared terminal network when the multi-connection terminal becomes a terminal network user is [9H, 18H] every day.

[0155] In actual application, the specific communication mode indicated by the ninth information can be set according to network sharing requirements; illustratively, the communication mode indicated by the ninth information can include D2D communication and / or WLAN communication, etc.

[0156] In actual application, the first function may determine the first list based on the location and / or trajectory of the multi-connection terminal and the network sharing requirement of the multi-connection terminal.

[0157] Based on this, in one embodiment, determining the first list for the first geographical area may include:

[0158] Determining a plurality of terminals that meet a first condition and first information of each terminal based on at least one of the following:

[0159] Terminal location information;

[0160] Terminal trajectory information;

[0161] The second information of the terminal can reflect the network sharing requirement of the terminal.

[0162] In actual application, the specific type of the location information can be determined according to needs; for example, the location information can include real-time cellular network location information and / or Global Navigation Satellite System (GNSS) location information.

[0163] In actual application, the first function may query the second function for the terminal's location information and / or trajectory information. The specific type of the second function may be determined according to requirements. Exemplarily, the second function may include a Network Access Control Function (NACF) and / or an Access and Mobility Management Function (AMF).

[0164] In actual application, the first condition may also be referred to as a network sharing networking condition or a terminal network sharing networking condition, etc. The embodiment of the present disclosure does not limit the name and specific content of the first condition, as long as its function is achieved. For example, the first condition may include at least one of the following:

[0165] The plurality of terminals located in the first geographical area include first-category terminals and second-category terminals;

[0166] Among the multiple terminals located in the first geographical area, the network access mode supported by the first type of terminals can meet the QoS requirements of the second type of terminals;

[0167] Among multiple terminals located in the first geographical area, the relative mobility between the first type of terminals and the second type of terminals can enable the network access method supported by the first type of terminals to meet the QoS requirements of the second type of terminals; wherein, when network sharing is performed between terminals, the second type of terminals can access the corresponding network through the first type of terminals.

[0168] In actual application, the multiple terminals located in the first geographical area include first-category terminals and second-category terminals, which can be understood as the presence of both terminal network sharers and terminal network users in the first geographical area. Furthermore, it can be understood that if the terminals in the first geographical area do not meet the first condition, that is, if the first list does not exist that meets the first condition, the terminals in the first geographical area will not share the network between terminals. At this point, if the first function receives the at least one first request, it can send a notification message to each terminal that sent the first request, indicating that these terminals cannot share the network between terminals in the first geographical area.

[0169] In actual application, when determining the first information of each terminal, the first function may determine the first-category terminal as a master node or a backup master node, and determine the second-category terminal as a slave node. Specifically, when there is only one first-category terminal, the first function may determine the first-category terminal as the master node. When there are at least two first-category terminals, the first function may determine the network sharing priority of each first-category terminal, determine the first-category terminal with the highest network sharing priority as the master node, and determine the first-category terminal with the second-highest network sharing priority as the backup master node. Other first-category terminals other than the master node and the backup master node may not participate in inter-terminal network sharing.

[0170] Based on this, in one embodiment, determining the first information of each terminal may include:

[0171] determining each second-category terminal included in the plurality of terminals satisfying the first condition as a slave node;

[0172] In the case where the multiple terminals that meet the first condition include only one first-class terminal, the first-class terminal is determined as the master node; or, in the case where the multiple terminals that meet the first condition include at least two first-class terminals, the network sharing priority of each first-class terminal is determined, and based on the network sharing priority of each first-class terminal, a master node and at least one backup master node are determined from the at least two first-class terminals; wherein, when network sharing is performed between terminals, the second-class terminal can access the corresponding network through the first-class terminal.

[0173] In actual application, if the multiple terminals that meet the first condition include at least two first-category terminals, the first function may determine the network sharing priority of each first-category terminal based on its current network connection status, with first-category terminals with better network connection status having higher network sharing priority. In other words, when the network connection status of first-category terminal_1 is better than that of first-category terminal_2, the network sharing priority of first-category terminal_1 is higher than that of first-category terminal_2. The specific content of the network connection status can be determined based on actual needs; illustratively, the network connection status may include at least one of network performance information such as network access mode, access rate, latency, and packet loss rate.

[0174] In actual application, determining a master node and at least one backup master node from the at least two first-category terminals based on the network sharing priority of each first-category terminal may include: determining the first-category terminal with the highest network sharing priority as the master node, and determining the first-category terminal with the second-highest network sharing priority as the backup master node. It is understood that first-category terminals other than the master node and the backup master node may not participate in inter-terminal network sharing.

[0175] In actual application, during the process of network sharing between terminals between the master node and at least one slave node, when the master node is unable to share the network between terminals (for example, in the event of a link failure, etc.), if there is a backup master node, the backup master node can provide terminal network sharing, and the backup master node will report the information of switching from the master node to the backup master node (which can be recorded as the tenth information in the subsequent description) to the first function. The first function does not need to re-organize the terminal network sharing, that is, there is no need to update the first list.

[0176] Based on this, in one embodiment, the method may further include:

[0177] When the master node cannot share the network between terminals, the tenth information sent by the backup master node is received, and the tenth information is used to instruct the slave node to switch from accessing the corresponding network through the master node to accessing the corresponding network through the backup master node.

[0178] In actual application, during the process of network sharing between terminals between the master node and at least one slave node, when the master node is unable to share the network between terminals (for example, when a link failure occurs), if there is no backup master node, or the backup master node is also unable to share the network between terminals, the slave node may report the information that the master node and the backup master node are unable to share the network between terminals (which may be recorded as the eleventh information in subsequent descriptions) to the first function, and the first function may re-organize the terminal network sharing, that is, update the first list.

[0179] Based on this, in one embodiment, the method may further include:

[0180] receiving eleventh information sent by the slave node, where the eleventh information is used to indicate that the master node cannot perform network sharing between terminals, and there is no backup master node in the first geographical area or the backup master node is also unable to perform network sharing between terminals;

[0181] The first list is updated, and the updated first list is sent to each terminal in the updated first list, so that each terminal acts as a master node, a backup master node, or a slave node to perform inter-terminal network sharing according to the updated first list.

[0182] In actual application, the first function can send a service request to the ground-based and / or space-based service platform (which may be referred to as the first platform in the subsequent description) based on the network sharing needs of multiple connected terminals located in the first geographical area, and the first platform will open the terminal network sharing service for the user (which may be referred to as the first service in the subsequent description).

[0183] Based on this, in one embodiment, the method may further include:

[0184] receiving second information sent by a terminal located in the first geographical area, and storing the second information, where the second information can reflect a network sharing requirement of the terminal;

[0185] Based on the second information, a second request is sent to the first platform, where the second request is used to request activation of a first service for the terminal, and the first service is associated with a network sharing between the terminal.

[0186] In actual application, when the first platform activates the first service for the terminal, information such as service rates and / or service discounts may be determined.

[0187] In actual application, the first functions deployed in different networks can perform real-time incremental synchronization and / or periodic full verification on the second information, thereby supporting users to use terminal network sharing services under fixed, mobile and satellite access.

[0188] Based on this, in one embodiment, the method may further include:

[0189] For all second information associated with the first geographical area, incremental synchronization and / or periodic full verification are performed with the first function in other networks among the multiple networks except the network to which the first function belongs, and the second information can reflect the network sharing requirements of the terminal.

[0190] In one embodiment, the network sharing between terminals may include traffic sharing and / or content sharing. The method may further include:

[0191] receiving twelfth information sent by the master node, the twelfth information including billing information related to traffic sharing and / or content sharing of each of at least one slave node, each of the at least one slave node using a first service through the master node, the first service being associated with network sharing between terminals;

[0192] The twelfth information is sent to the first platform, so that the first platform performs billing processing on each of the at least one slave node based on the twelfth information.

[0193] Among them, in actual application, in the process of traffic sharing between terminals between the master node and at least one slave node, the master node can support recording the traffic used by each slave node, distinguishing the traffic used by the master node under different access methods, and support generating traffic billing information (i.e., the twelfth information) for the slave node based on the traffic used by the slave node and the corresponding master node access method, and sending the traffic billing information to the first function; after the first function receives the traffic billing information, it can use a preset specific method to verify the traffic billing information, and after the verification is passed, send the traffic billing information to the first platform, and then the first platform will combine the traffic billing information and the service subscription information of the relevant users (such as service rates and / or service discounts, etc.) to perform traffic billing processing for the relevant users.

[0194] In actual application, during the process of content sharing between terminals between the master node and at least one slave node, the master node can support recording the content obtained by each slave node, distinguishing the content obtained under different access methods of the master node, and supporting the generation of content billing information (i.e., the twelfth information) for the slave node based on the content obtained by the slave node and the corresponding master node access method, and sending the content billing information to the first function; after the first function receives the content billing information, it can use a preset specific method to verify the traffic billing information, and after the verification is passed, send the content billing information to the first platform, and then the first platform will combine the content billing information and the service subscription information of the relevant users (such as service rates and / or service discounts, etc.) to perform content billing processing for the relevant users.

[0195] Accordingly, an embodiment of the present disclosure further provides a network sharing method, which is applied to a terminal. As shown in FIG3 , the method includes:

[0196] Step 301: When there is a demand for network sharing between terminals in a first geographical area, receiving a first list sent by a first function, the terminal being located in the first geographical area, the first list including multiple terminals that meet a first condition and first information of each terminal, the first condition indicating that the multiple terminals are capable of performing network sharing between terminals in the first geographical area, the first information indicating that the terminal functions as a master node, a backup master node, or a slave node for performing network sharing between terminals, each terminal having the ability to access multiple networks, and the first function belonging to any of the multiple networks;

[0197] Step 302: According to the first list, the node serves as a master node, a backup master node, or a slave node to perform network sharing among terminals.

[0198] When network sharing is performed between terminals, the slave node can access the corresponding network through the master node or the backup master node.

[0199] In one embodiment, before receiving the first list sent by the first function, the method may further include:

[0200] A first request is sent to the first function, where the first request is used to request network sharing between terminals.

[0201] In one embodiment, before receiving the first list sent by the first function, the method may further include:

[0202] Sending second information to the first function, where the second information can reflect the network sharing requirement of the terminal.

[0203] In one embodiment, when the terminal serves as a standby master node to perform network sharing among terminals, the method may further include:

[0204] When the master node is unable to share the network between terminals, a tenth message is sent to the first function, wherein the tenth message is used to instruct the slave node to switch from accessing the corresponding network through the master node to accessing the corresponding network through the backup master node.

[0205] In one embodiment, when the terminal acts as a slave node to perform network sharing among terminals, the method may further include:

[0206] Sending eleventh information to the first function, where the eleventh information is used to indicate that the master node cannot perform network sharing between terminals, and that there is no backup master node in the first geographical area or the backup master node cannot perform network sharing between terminals;

[0207] The updated first list is received, and according to the updated first list, the node performs network sharing among terminals as a slave node.

[0208] In one embodiment, the network sharing between terminals includes traffic sharing and / or content sharing; when the terminal acts as a master node to perform network sharing between terminals, the method may further include:

[0209] determining twelfth information, the twelfth information including billing information related to traffic sharing and / or content sharing of each of at least one slave node, each of the at least one slave node using a first service through the master node, the first service being associated with network sharing between terminals;

[0210] The twelfth information is sent to the first function.

[0211] The network sharing method provided by the embodiment of the present disclosure has a first function, in which, when there is a demand for network sharing between terminals in a first geographical area, a first list is determined for the first geographical area, the first list including multiple terminals that meet a first condition and first information of each terminal, the first condition indicating that the multiple terminals can perform network sharing between terminals in the first geographical area, the first information indicating that the terminal acts as a master node, a backup master node or a slave node to perform network sharing between terminals, each terminal has the ability to access multiple networks, and the first function belongs to any network among the multiple networks; the first list is sent to each of the multiple terminals, so that each terminal acts as a master node, a backup master node or a slave node to perform network sharing between terminals according to the first list; wherein, when performing network sharing between terminals, the slave node can access the corresponding network through the master node or the backup master node. The solution provided by the embodiment of the present disclosure is for a fixed, mobile and satellite converged network, and a network function (i.e., the first function) is added to the ground-based core network and / or the space-based core network for managing and centrally controlling terminal network sharing. When there is a demand for network sharing between terminals in a specific area (i.e., the first geographical area), the function determines a terminal list (i.e., the first list) for the area. The multiple terminals included in the list meet a specific condition (i.e., the first condition), that is, the multiple terminals included in the list can perform network sharing between terminals in the area, and each terminal included in the list can serve as a master node, a backup master node or a slave node for network sharing between terminals (when performing network sharing between terminals, the slave node can connect to the master node or the backup master node through the master node or the backup master node). Enter the corresponding network), the function sends the list to each terminal included in the list, so that each terminal acts as a master node, a backup master node or a slave node according to the list to share the network between terminals; in this way, when the network function newly added to the ground-based core network and / or the space-based core network for managing and centrally controlling terminal network sharing determines the terminal list for network sharing between terminals, it can fully consider the differences in fixed, mobile and satellite access capabilities, that is, it can enable the multiple terminals included in the list to meet specific conditions, that is, it can enable the multiple terminals included in the list to share the network between terminals in the area, thereby effectively reducing the probability of terminal network sharing failure and the probability that the terminal network does not meet the sharing requirements, that is, it can at least solve the above-mentioned problem 1.

[0212] In addition, according to the solution provided by the embodiment of the present disclosure, the multi-connected terminal can configure the network sharing requirement (i.e., the above-mentioned second information) to the first function, and the first function can organize the terminal network sharing based on the network sharing requirement of the multi-connected terminal (i.e., determine the first list). In this way, the first function can fully consider the network sharing requirement of the multi-connected terminal when organizing the terminal network sharing, thereby making full use of the limited resources of the terminal network and ensuring the efficiency and reliability of terminal network sharing, that is, it can at least solve the above-mentioned problem 2.

[0213] In addition, in the solution provided by the embodiment of the present disclosure, the first function can query the NACF / AMF (i.e., the second function) for the real-time location information and / or trajectory of the multi-connected terminal, and determine a list of multi-connected terminals (i.e., the first list) that meets the terminal network sharing networking conditions (i.e., the first condition) based on the real-time location information and / or trajectory of the multi-connected terminal. In this way, the first function can fully consider the real-time location information and / or trajectory of the multi-connected terminal when organizing the terminal network sharing (i.e., determining the first list), thereby supporting the strong mobility of the terminal and the dynamic topology characteristics of the terminal network, so that the stability and robustness of the terminal network sharing are significantly improved, that is, at least the above-mentioned problem 3 can be solved.

[0214] It should be noted that in various embodiments of the present disclosure, the functions in the network (i.e., the first function, the second function) can also be referred to as network functions, functional bodies, network nodes, network elements or devices, etc. The embodiments of the present disclosure do not limit this, as long as their functions are realized.

[0215] The present disclosure is further described in detail below with reference to application examples.

[0216] This application example addresses the above-mentioned issues 1, 2, and 3 by proposing a terminal network sharing system, method, and corresponding process for a fixed, mobile, and satellite converged network. Specifically, in response to the above-mentioned issue 1, this application example proposes a terminal network sharing system, method, and corresponding process for a fixed, mobile, and satellite converged network. The system fully considers the differences in fixed, mobile, and satellite access capabilities in the terminal network sharing organization, and adds a terminal network sharing management function (i.e., the above-mentioned first function) for centralized control. In response to the above-mentioned issue 2, this application example proposes a terminal network sharing demand configuration method. Users configure terminal network sharing demands (i.e., the above-mentioned second information) on a multi-connected terminal, which may include information such as the terminal network role, access method, access requirements, sharing / usage time period, and communication method, and is used for terminal network sharing organization. In response to the above-mentioned issue 3, this application example proposes that the terminal network sharing management function query the NACF / AMF for the real-time location information and / or trajectory of the multi-connected terminal to determine a list of multi-connected terminals (i.e., the above-mentioned first list) that meet the terminal network sharing networking conditions (i.e., the above-mentioned first conditions).

[0217] In this application example, as shown in Figure 4, the terminal network sharing system integrating fixed, mobile and satellite includes: multi-connection terminals, fixed access network, mobile access network, satellite access network, ground-based core network, space-based core network, intercommunication function, ground-based data network, space-based data network, ground-based service platform, space-based service platform and other logical units;

[0218] The multi-connection terminal is used to support fixed, mobile and satellite access, and supports the user to configure the terminal network sharing requirements (i.e. the second information mentioned above);

[0219] The fixed / mobile / satellite access network is used to provide multiple access modes for multi-connection terminals, including at least one of fixed wired / wireless access, at least one of 2G / 3G / 4G / 5G / 6G mobile access, and at least one of GEO / MEO / LEO satellite access;

[0220] The ground-based / space-based core network is configured to support a newly added terminal network sharing management function (i.e., the first function described above) and terminal network sharing organization, i.e., support determination of a list of multi-connected terminals (i.e., the first list described above) that meet the terminal network sharing networking conditions (i.e., the first condition described above); the NACF / AMF in the ground-based / space-based core network supports provision of real-time location information and / or trajectories of multi-connected terminals;

[0221] The intercommunication function is used to realize the intercommunication between the ground-based core network and the space-based core network;

[0222] The ground-based / space-based data network is used to provide Internet access;

[0223] The ground-based / space-based service platform is used to provide communication services and information services, and supports billing processing for new terminal network sharing services (such as traffic sharing and / or content sharing, etc.).

[0224] In this application example, the user can configure the terminal network sharing requirements on the multi-connection terminal. Specifically, the user can configure the terminal network sharing requirements (i.e., determine the above-mentioned second information) on the application or setting interface of the multi-connection terminal. The configuration may include the following information:

[0225] 1) Terminal network role configuration (i.e., the third and fourth information mentioned above), which may include whether the terminal supports becoming a terminal network sharer (i.e., the first type of terminal mentioned above), and whether the terminal supports becoming a terminal network user (i.e., the second type of terminal mentioned above);

[0226] 2) The access methods supported when becoming a terminal network sharer (i.e., the fifth information above) may include one or more access methods selected from fixed / wired / wireless access, 2G / 3G / 4G / 5G / 6G mobile access, and GEO / MEO / LEO satellite access;

[0227] 3) The time period for sharing the terminal network when becoming a terminal network sharer (i.e., the sixth information mentioned above), for example, sharing the terminal network every day [20 hours, 24 hours];

[0228] 4) QoS requirements such as access rate, delay, and packet loss rate when becoming a terminal network user (i.e., the seventh information above), for example, access rate > 10Mbps, delay < 100ms, packet loss rate < 10 -4 ;

[0229] 5) The time period during which the terminal network is used when becoming a terminal network user (i.e., the eighth information mentioned above), for example, using the terminal network from [9:00 AM to 6:00 PM] every day;

[0230] 6) Terminal network communication mode (ie, the ninth information above), such as supporting D2D communication, ie, using D2D communication between multiple connected terminals; or, not supporting D2D communication, and using WLAN communication between multiple connected terminals.

[0231] In this application example, the multi-connection terminal can synchronize the user's terminal network sharing demand configuration (i.e., the above-mentioned second information) to the terminal network sharing management function (i.e., the above-mentioned first function) of the ground-based and / or space-based core network; the terminal network sharing management function of the ground-based and / or space-based core network can store the user's terminal network sharing demand configuration and send a service request (i.e., the above-mentioned second request) to the ground-based and / or space-based service platform, and the ground-based and / or space-based service platform will open the terminal network sharing service (i.e., the above-mentioned first service) for the user, including clear information such as service rates and / or service discounts. The user can update the terminal network sharing demand configuration on the multi-connection terminal as needed; accordingly, the terminal network sharing management function can update the user's terminal network sharing demand configuration. In addition, the terminal network sharing management functions of the ground-based / space-based core network can perform real-time incremental synchronization and / or periodic full verification of the user's terminal network sharing demand configuration, thereby supporting users to use terminal network sharing services under fixed, mobile and satellite access.

[0232] In this application example, the terminal network sharing management function (i.e., the first function) of the ground-based and / or space-based core network can collaborate with the multi-connected terminal, and the NACF and / or AMF (i.e., the second function) to organize terminal network sharing. Specifically, when multiple users in a designated geographical area (i.e., the first geographical area) wish to use the terminal network sharing service, the relevant multi-connected terminal can send a terminal network sharing request (i.e., the first request) to the terminal network sharing management function of the ground-based and / or space-based core network. After receiving the terminal network sharing request, the terminal network sharing management function can query the NACF and / or AMF of the ground-based and / or space-based core network for the real-time location information (which may include cellular network location information and / or GNSS location information, etc.) and / or trajectory of the relevant multi-connected terminal. The terminal network sharing management function can determine a list of multi-connected terminals (i.e., the first list) that meets the terminal network sharing networking conditions (i.e., the first condition) based on the real-time location information and / or trajectory of the relevant multi-connected terminals and the locally stored terminal network sharing requirement configuration (i.e., the second information).

[0233] The terminal network sharing networking conditions (i.e., the first condition mentioned above) may specifically include:

[0234] 1) Based on the real-time location information of the multi-connected terminal, it is determined that in a designated geographical area (i.e., the first geographical area), there are both terminal network sharers (i.e., the first type of terminals) and terminal network users (i.e., the second type of terminals);

[0235] 2) Based on the trajectories of the multi-connected terminals, determining whether the relative mobility of the terminal network sharers and the terminal network users meets the networking conditions (i.e., the relative mobility enables the access method currently used by the terminal network sharers (or also understood as the supported network access method) to meet the QoS requirements of the terminal network users, such as access rate, latency, and packet loss rate);

[0236] 3) Determine whether the access method currently used by the terminal network sharer can meet the QoS requirements of the terminal network user, such as access rate, delay, and packet loss rate.

[0237] In this application example, the terminal network user that meets the above requirements can be determined as a slave node. When there are multiple terminal network sharers that meet the above requirements (i.e., the first type of terminal mentioned above), the priority of the terminal network sharer can be determined based on the current network connection conditions of the relevant multi-connection terminal, and the multi-connection terminal with better connection conditions (such as access rate, latency, and packet loss rate) has a higher priority; at this time, the terminal network sharer with the highest priority can be determined as the master node, and the terminal network sharer with the second highest priority can be determined as the backup master node, and other terminal network sharers may not participate in terminal network sharing. In addition, if there is no multi-connection terminal list (i.e., the first list mentioned above) that meets the terminal network sharing networking conditions (i.e., the first condition mentioned above), terminal network sharing will not be performed.

[0238] In this application example, the terminal network sharing management function can send a list of multi-connected terminals (i.e., the first list) that meet the terminal network sharing networking conditions (i.e., the first condition) to relevant multi-connected terminals in a specified geographical area (i.e., the first geographical area). Based on the multi-connected terminal list, the multi-connected terminal can become a master node, a backup master node, or a slave node. The master node can share the terminal network using D2D communication or WLAN communication; the slave node can access the Internet through the terminal network shared by the master node and use communication services, information services, and new terminal network sharing services.

[0239] In this application example, when the master node is unable to provide terminal network sharing, if there is a backup master node, the backup master node will provide terminal network sharing and report this information (i.e., the tenth information) to the terminal network sharing management function (i.e., the first function); the terminal network sharing management function does not reorganize the terminal network sharing. If there is no backup master node or the backup master node is also unable to provide terminal network sharing, the slave node will report this information (i.e., the eleventh information) to the terminal network sharing management function, and the terminal network sharing management function will need to reorganize the terminal network sharing.

[0240] In this application example, based on the terminal network sharing system, a new terminal network sharing service (i.e., the first service mentioned above) can be provided, including a terminal network traffic sharing service and a terminal network content sharing service. Among them, the terminal network traffic sharing service refers to the sharing of traffic between the terminal network sharer (i.e., the master node) and the user (i.e., the slave node) based on the terminal network sharing. The user can go to the ground-based and / or space-based service platform (i.e., the first platform mentioned above) to subscribe to the terminal network traffic sharing service; the master node can support recording the traffic used by each slave node and distinguishing the traffic used under different access modes of the master node. The master node can also support generating traffic billing information (i.e., the twelfth information mentioned above) for the slave node based on the traffic used by the slave node and the corresponding master node access mode, and sending the traffic billing information to the terminal network sharing management function (i.e., the first function mentioned above); the terminal network sharing management function can verify the traffic billing information and send it to the ground-based and / or space-based service platform; the ground-based and / or space-based service platform can combine the service subscription information of the relevant user (such as service rate and / or service discount information) to perform traffic billing processing for the relevant user. The terminal network content sharing service refers to content sharing between the terminal network sharer (i.e., the master node) and the user (i.e., the slave node) based on the terminal network sharing. The user can subscribe to the terminal network content sharing service on the ground-based and / or space-based service platform; the master node can support recording the content obtained by each slave node, and distinguish the content obtained under different access methods of the master node. The master node can also support generating content billing information (i.e., the above-mentioned twelfth information) for the slave node based on the content obtained by the slave node and the corresponding master node access method, and send the content billing information to the terminal network sharing management function; the terminal network sharing management function can verify the content billing information and send it to the ground-based and / or space-based service platform; the ground-based and / or space-based service platform can combine the service subscription information of the relevant users (such as service rates and / or service discounts, etc.) to perform content billing processing for the relevant users.

[0241] In this application example, as shown in FIG5 , the terminal network sharing process for fixed, mobile, and satellite convergence may include the following steps:

[0242] Step 501: Users 1 to N (N is an integer greater than or equal to 2) configure terminal network sharing requirements on the multi-connection terminal, and then execute step 502;

[0243] Step 502: The multi-connection terminals 1-N synchronize the terminal network sharing requirement configurations of users 1-N (i.e., the second information) to the terminal network sharing management function (i.e., the first function) of the ground-based and / or space-based core network, and then execute step 503;

[0244] Step 503: The terminal network sharing management function sends a service request to the ground-based and / or space-based service platform, and the ground-based and / or space-based service platform opens the terminal network sharing service for the user, and then executes step 504;

[0245] Here, the service request sent is used to activate the terminal network sharing service for the corresponding user;

[0246] Step 504: The relevant multi-connection terminal sends the terminal network sharing request (i.e., the first request) of users 1 to N to the terminal network sharing management function, and then executes step 505;

[0247] Step 505: The terminal network sharing management function queries the NACF / AMF of the ground-based and / or space-based core network for real-time location information and / or trajectory of the relevant multi-connected terminals, and then executes step 506;

[0248] Step 506: The terminal network sharing management function determines a list of multi-connection terminals (i.e., the first list) that meets the terminal network sharing networking condition (i.e., the first condition) based on the real-time location information and / or trajectory of the relevant multi-connection terminals and the locally stored terminal network sharing requirement configuration, and then executes step 507;

[0249] Step 507: The terminal network sharing management function sends the multi-connection terminal list that meets the terminal network sharing networking conditions to the relevant multi-connection terminals in the designated geographical area, and then executes step 508;

[0250] Step 508: The multi-connection terminal becomes a master node, a backup master node, or a slave node according to the multi-connection terminal list, and then executes step 509;

[0251] Here, the master node uses D2D communication or WLAN communication to share the terminal network;

[0252] Step 509: The slave node accesses the Internet through the terminal network shared by the master node and uses the terminal network to share the new service (i.e., the first service mentioned above), and then executes step 510;

[0253] Step 510: The master node generates traffic and / or content billing information (i.e., the twelfth information) for the slave node based on the traffic and / or content used by the slave node and the access mode of the corresponding master node, and sends it to the terminal network sharing management function, and then executes step 511;

[0254] Step 511: After verifying the traffic and / or content billing information, the terminal network sharing management function sends it to the ground-based and / or space-based service platform (i.e., the first platform mentioned above). The ground-based and / or space-based service platform combines the service subscription information (such as service rates and / or service discounts, etc.) to process the traffic and / or content billing for the relevant users.

[0255] This application example proposes a terminal network sharing system, method and corresponding process that integrates fixed, mobile and satellite networks. It also proposes adding terminal network sharing management functions to ground-based and / or space-based core networks. NACF / AMF supports providing real-time location information and / or trajectories of multiple connected terminals. It also proposes a terminal network sharing demand configuration method, a terminal network sharing organization method, and a new terminal network sharing service method. These methods can fully utilize the limited resources of the terminal network and ensure the success rate, efficiency, reliability, stability and robustness of terminal network sharing. In addition, the system requires relatively little modification to the end-to-end network, and has good application prospects, outstanding economic benefits, and high commercial value.

[0256] Specifically, the solution provided by this application example has the following advantages:

[0257] 1) This application example proposes a terminal network sharing system, method, and corresponding process for a converged fixed, mobile, and satellite network. It fully considers the differences in fixed, mobile, and satellite access capabilities in the organization of terminal network sharing and adds a terminal network sharing management function for centralized control. Because it fully adapts to the characteristics of a converged fixed, mobile, and satellite network and organizes terminal network sharing through a centralized control node (i.e., the terminal network sharing management function, also known as the first function described above), it can effectively reduce the probability of terminal network sharing failure and the probability of a terminal network not meeting sharing requirements.

[0258] 2) This application example proposes a method for configuring terminal network sharing requirements. Users configure terminal network sharing requirements on multi-connected terminals, including information such as terminal network role, access method, access requirements, sharing / usage time period, and communication method. This configuration is then used to organize terminal network sharing. By fully considering the user's terminal network sharing requirements, the limited resources of the terminal network can be fully utilized, thereby ensuring the efficiency and reliability of terminal network sharing.

[0259] 3) This application example proposes that the terminal network sharing management function queries the NACF / AMF for the real-time location information and / or trajectory of multi-connected terminals to determine a list of multi-connected terminals that meet the terminal network sharing networking conditions. Since the real-time location information and / or trajectory of multi-connected terminals are taken into account in the terminal network sharing organization, it can support the strong mobility of the terminal and the dynamic topology characteristics of the terminal network, thereby significantly improving the stability and robustness of terminal network sharing.
