Description

An access method, apparatus, and storage medium

[0002] This disclosure relates to the field of communication technology, and more specifically, to an access method, apparatus, and storage medium. Background Technology

[0003] A mobile communication network is a wireless communication network that allows user equipment (UE) to communicate and transmit data over a wide geographical area. In scenarios where satellite access is used for mobile communication networks, the base station on the satellite can connect to multiple mobile communication networks.

[0004] Different mobile communication networks have different satellite network elements or functions that can be shared. For example, mobile communication network A deploys satellites, and these satellites deploy base stations, User Plane Functions (UPFs), Access and Mobility Management Functions (AMFs), and Session Management Functions (SMFs), etc. These network elements can be shared with other mobile communication networks. Mobile communication network B can use the base stations on the satellites, and mobile communication network C can use the SMFs and UPFs on the satellites. In this case, the UE's choice of different mobile communication networks will result in different signaling and data processing delays, and the security guarantees that can be provided will also differ.

[0005] When selecting a mobile communication network, the choice is usually made based on the priority of each mobile communication network. This selection method may result in the UE selecting a mobile communication network with long processing delays or low security, and insufficient adaptability to its own needs.

[0254] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown herein can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0255] The following explanations of some terms used in the embodiments of this disclosure are provided to facilitate understanding by those skilled in the art.

[0256] In this disclosure, the term "multiple" refers to two or more objects, and other quantifiers are similar. In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0257] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0258] This disclosure provides an access method, apparatus, and storage medium that can select a mobile communication network based on shared satellite information. This allows the UE to select a mobile communication network according to its own needs, such as latency and / or security requirements, thereby improving the reliability of network selection and ensuring that the user can connect to the most suitable network, thus enhancing the access experience.

[0259] The method and apparatus are based on the same inventive concept. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0260] The technical solutions provided in this disclosure can be applied to a variety of systems. For example, applicable systems may include Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G New Radio (NR) systems and their evolved communication systems, and 6G (sixth generation mobile communication technology) systems. These systems may include terminal equipment and network equipment. The systems may also include a core network component, such as the Evolved Packet Core (EPC) or the 5G Core Network (5GC).

[0261] The terminal devices involved in the embodiments of this disclosure can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in 5G or 6G systems, the terminal device may be called User Equipment (UE). Wireless terminal devices can be USB storage devices, other personal computer memory devices, and dongles. They can also communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the radio access network. Examples of such devices include Personal Communication Service (PCS) telephones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), personal computers, tablets, and Machine-type Communication (MTC) terminal devices. Wireless terminal devices can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, access points, remote terminals, access terminals, user terminals, user agents, user devices, and wireless access devices and routers / modems that meet the limitations of this definition, but are not limited to these in the embodiments of this disclosure.

[0262] The network device involved in this disclosure may include a base station, which may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with wireless terminal devices through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network device may be an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, or a Home evolved Node B (HeNB), relay node, femto, pico, network testing equipment, etc., which are not limited in this disclosure. In some network architectures, network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes, which may also be geographically separated.

[0263] For example, referring to Figure 1, which is a schematic diagram of a communication system provided in an embodiment of this disclosure, the communication system may include satellites deployed in a mobile communication network 1, user equipment (UE), and gateway stations. Base stations (gNBs) may be deployed on the satellites, and these base stations can be shared with other mobile communication networks (in Figure 1, the mobile communication network is an example of a Public Land Mobile Network (PLMN)). The gateway station can act as a data routing node, responsible for the distribution and collection of satellite communication service data, and can complete the exchange of data within the communication system and data routing to external networks. Through the gateway station, the base station's data can be transmitted to PLMN1 and shared by PLMN2 and PLMN3, thereby realizing the sharing of data between the base station and multiple mobile communication networks.

[0264] Referring to Figure 2, which is a schematic diagram of another communication system provided in an embodiment of this disclosure, a base station gNB and a user plane function (UPF) can be deployed on the satellite in this communication system. The base station and UPF can be shared with PLMN2 and PLMN3 through a gateway station.

[0265] Referring to Figure 3, which is a schematic diagram of another communication system provided in this embodiment of the present disclosure, the satellite in this communication system can be deployed with a base station gNB, a user plane function (UPF), an access and mobility management function (AMF), a session management function (SMF), and a unified data management function (UDM). The base station, UPF, AMF, SMF, and UDM can all be shared with PLMN2 and PLMN3 through a gateway station.

[0266] As can be seen, there are various types of network elements deployed on satellites, offering diverse functionalities, and varying degrees of sharing among these elements. Due to these differing sharing configurations, different mobile communication networks exhibit varying latency and security characteristics. For example, if frequent interactions are required between satellite-deployed and ground-based network elements, the interaction data will be transmitted multiple times between the satellite and ground stations, resulting in longer latency for the mobile communication network. Furthermore, if network elements involved in information security are shared, the network's security will be lower. For these reasons, simply prioritizing a mobile communication network may prevent the UE from selecting the most suitable network.

[0267] Therefore, this disclosure provides an access method that carries information indicating the sharing of satellites by the mobile communication network in the network configuration information or network priority information. This allows the UE to consider the shared satellite information of the mobile communication network when selecting a mobile communication network, and to select a mobile communication network based on requirements such as processing latency and / or security. This improves the reliability of network selection, ensures that the user can connect to the most suitable network, and thus enhances the access experience.

[0268] The following describes the access method provided in this embodiment, taking the user equipment (UE) in the aforementioned satellite as the executing entity.

[0269] Referring to Figure 4, which is a schematic diagram of an access method provided in an embodiment of this disclosure, the executing entity of which can be a user equipment (UE), the method includes:

[0270] S401, Receive network configuration information; the network configuration information includes identification information of at least one mobile communication network and first sharing indication information; the first sharing indication information is used to indicate the sharing information of the mobile communication network with the satellite.

[0271] This network configuration information can be sent by Radio Access Network Nodes (RAN) deployed on satellites. RAN nodes are a fundamental component of the Radio Access Network (RAN) and are responsible for handling wireless communication between User Equipment (UE) and the core network. RAN nodes mainly include base stations and related control equipment, acting as a bridge connecting UE and the core network in mobile communication networks. RAN nodes can include NodeBs in 3G UMTS networks, eNodeBs (Evolved Node Bs) in 4G LTE networks, and gNodeBs in 5G NR networks, among others.

[0272] For example, RAN nodes can send information to the UE via system information broadcasting, paging messages, RRC (Radio Resource Control Signaling) signaling, NAS (Non-Access Stratum Signaling) signaling, etc.

[0273] The aforementioned network configuration information may include essential information required by the UE to access the network and maintain connectivity. Its content may include identification information of at least one mobile communication network provided by satellite, which can be presented in a list format. Typically, the network configuration information may also include one or more of the following: cell identification information, radio resource control information, quality of service information, handover information, security and authentication information, channel configuration and control information, time synchronization and positioning information.

[0274] For example, the network configuration information described above may include a list of Public Land Mobile Networks (PLMNs). This list may contain one or more available PLMN identifiers, indicating which public land mobile networks the UE can access.

[0275] In some possible implementations, the network configuration information described above may also indicate a list of Standalone Non-Public Networks (SNPNs). An SNPN can be a private network deployed specifically for a particular user, and the SNPN may contain information related to how a UE connects to the SNPN.

[0276] In this embodiment of the disclosure, the mobile communication network may include a PLMN and / or an SNPN.

[0277] The aforementioned first sharing indication information can be used to indicate the sharing information of a mobile communication network with a satellite. For example, the first sharing indication information may include at least one of the following: shared network element identifier, shared network element level, and shared network function. Specifically, the shared network element identifier can be the identification information of a network element shared by multiple mobile communication networks, such as the aforementioned gNB, AMF, and SMF; the shared network function can be, for example, the identification information of mobility management functions, session management functions, access network sharing, and access network and core network sharing; the shared network element level can indicate the degree of network element sharing in the mobile communication network. For example, Level 1 can indicate that the shared network element of the mobile communication network is a core network user plane network element, Level 2 can indicate a core network control plane network element, and Level 3 can indicate that the shared network element of the mobile communication network is a RAN node.

[0278] In one possible implementation, the aforementioned network configuration information can be obtained by the RAN node from the Operation Administration and Maintenance (OAM) equipment of the mobile communication network and then sent out.

[0279] Specifically, the first OAM device can configure OAM device connection information for the RAN node and send the OAM device connection information to the RAN node. This OAM device connection information can indicate the time points at which multiple different second OAM devices are connected, as well as the address information of the second OAM devices. The second OAM device can provide its corresponding network configuration information, which may indicate the identification information of at least one mobile communication network and first sharing indication information. The first sharing indication information is used to indicate the sharing information of the mobile communication network with the satellite.

[0280] For example, when a RAN node determines, based on the satellite's ephemeris information, that a satellite has entered the coverage area of ​​the mobile communication network corresponding to the first OAM device, it can establish a communication connection with the first OAM device. The first OAM device can determine the aforementioned OAM connection information based on the ephemeris information and send it to the RAN node.

[0281] In this way, after the RAN node obtains the OAM device connection information, it can communicate with the second OAM device at the time of connection and obtain the network configuration information provided by the second OAM device.

[0282] In one possible implementation, the first sharing indication information of the aforementioned mobile communication network can also be sent to the RAN node via OAM connection information.

[0283] In the case where the mobile communication network includes a PLMN, the OAM connection information may include the contents shown in Table 1:

[0284] Table 1

[0285] In one possible implementation, when the OAM device is configured to broadcast different mobile communication networks during a specific time period or when a satellite covers certain areas, the satellite may broadcast information about both mobile communication networks. For example, when the satellite is at position 1, it may cover both mobile communication network 1 and mobile communication network 2. In this case, the broadcast list of mobile communication networks may include information about both mobile communication networks 1 and 2. When the satellite moves to position 2, it may cover both mobile communication networks 2 and 3, and the broadcast list of mobile communication networks may include information about both mobile communication networks 2 and 3. Alternatively, the broadcast information may group the broadcast mobile communication networks according to time periods and broadcast them together.

[0286] For example, when the mobile communication network includes a PLMN, the content of the above network configuration information may be as shown in Table 2 or Table 3:

[0287] Table 2

[0288] Table 3

[0289] Among them, the content of the first sharing indication information in Table 2 is the shared network element identification information, and the content of the first sharing indication information in Table 3 is the shared network element level.

[0290] S402. Based on network configuration information, determine the target mobile communication network to be accessed from at least one mobile communication network.

[0291] After obtaining the network configuration information, the UE can use it to select a target mobile communication network. Specifically, the UE can use network priority information to determine the target mobile communication network from the mobile communication networks indicated in the network configuration information.

[0292] The network priority information mentioned above is used to indicate the selection priority of each mobile communication network.

[0293] In this way, when the UE determines multiple mobile communication networks with the same priority based on the network priority information, it can also use the first sharing indication information carried in the network configuration information to further filter the selected mobile communication networks, thereby finding a target mobile communication network that better meets its own needs.

[0294] The UE can also directly determine the available mobile communication networks based on network priority information, and then use the first sharing indication information corresponding to the mobile communication network to determine whether the mobile communication network meets its own needs. If it does, it can be directly identified as the target mobile communication network. If it does not, it can filter the target mobile communication network from the current or next priority network.

[0295] When the UE determines the target mobile communication network based on the first sharing indication information, the UE can determine whether the mobile communication network meets its own requirements for latency, security, etc.

[0296] Sharing different network elements may introduce certain delays to different functions compared to terrestrial communication. For example, sharing base stations may lead to resource contention, sharing UPF may increase data processing delays, sharing AMF may increase UE registration, attachment, and handover delays, sharing SMF may increase session establishment and management delays, and sharing UDM may increase user equipment authentication and authorization delays.

[0297] Sharing different network elements may also bring certain security risks to different functions. For example, sharing a UDM will result in storing data from different users or operators in the same UDM. If data isolation and protection measures are not in place, it may lead to data leakage or unauthorized access. Sharing control layer network elements may lead to signaling attacks, access control and permission issues.

[0298] For example, a UE can determine whether a mobile communication network meets its own requirements based on the first sharing indication information of each mobile communication network. For instance, a UE can request that the control layer network elements (such as AMF, SMF, UDM) of the mobile communication network not share data, or it can request that one or more specific network elements not share data. Alternatively, the UE can determine the latency score and / or security score of the mobile communication network based on the first sharing indication information, and only select the mobile communication network if the score meets the UE's requirements.

[0299] The network priority information mentioned above can be pre-stored in the UE's Subscriber Identity Module (SIM). The type of SIM can be selected according to the actual situation (such as the type of communication system). The type of network priority information can include one or more types.

[0300] For example, when the mobile communication network includes a PLMN, the network priority information may include an equivalent local public land mobile network (EHPLMN) list and / or an operator-controlled PLMN selector with access technology list.

[0301] For example, when a mobile communication network includes an SNPN, the network priority information may include at least one of the following priority lists:

[0302] List of signed SNPNs; list of SNPNs controlled by the credential holder; list of SNPNs controlled by the credential holder that carries a Group ID for Network Selection (GIN).

[0303] The aforementioned EHPLMN list typically includes a set of PLMNs considered equivalent to the Home PLMN (HPLMN). The access technologies carried in the operator-controlled PLMN list refer to the various wireless access technologies that user equipment can use, such as GSM, UMTS, LTE, and NR. This information helps user equipment choose between different networks and access technologies to ensure optimal connection performance and quality of service.

[0304] The aforementioned SNPN lists typically indicate the mobile network identifier and network identifier (NID), and the UE possesses the network's 5G identifier SUPI and trusted credentials. SNPN lists controlled by the credential holder are lists of non-public networks managed by the user equipment (UE) or its credential holder (usually configured in the SIM card or eSIM). SNPN lists carrying GINs add the corresponding GIN to the SNPN list controlled by the credential holder.

[0305] In one possible implementation, not only can the network configuration information carry the first sharing indication information, but the network priority information can also include the second sharing indication information. In this case, the priority of the mobile communication network indicated in the network priority information can be determined by simultaneously considering the second sharing indication information and other requirements; or, it can be determined only according to other requirements, with the UE performing further priority determination based on the second sharing indication information.

[0306] For example, the network priority information may indicate an EHPLMN list, in which EHPLMNs can be arranged according to their priority. In addition to indicating the EHPLMN identifier, the information may also indicate the corresponding second sharing indication information. It is worth noting that, in some embodiments, the EHPLMN list may carry the second sharing indication information of some EHPLMNs, or all EHPLMNs, or it may not carry any second sharing indication information for any EHPLMNs.

[0307] For example, the contents of the EHPLMN list can be as follows:

[0308] EHPLMN1+ Shared Network Functions\Shared Network Element Identifier\Shared Network Element Level, EHPLMN2, EHPLMN3+ Shared Network Element Information\Shared Network Element Level.

[0309] The network priority information may also indicate a list of PLMNs controlled by the operator. For example, this PLMN list may indicate the mobile network identifiers of various mobile communication networks. In one possible implementation, the PLMN list may also indicate at least one of access time periods, access technology information, and second sharing indication information.

[0310] The access time period refers to the time during which the satellite can access the corresponding mobile communication network. This access time period can be the time during which the satellite is within the coverage area of ​​the mobile communication network, and can be determined through ephemeris information.

[0311] The aforementioned access technology information can indicate the access technology used by the UE when accessing the corresponding mobile update network, such as LTE, NR, GSM, UMTS, etc.

[0312] In one possible implementation, the aforementioned second sharing indication information can be indicated through access technology information. The second sharing indication information can be a part of the access technology information, and can be indicated by a field corresponding to the access technology type. In this case, in addition to the identifiers of each mobile communication network, the network priority information may also include at least one of the following: access time period and access technology information.

[0313] The aforementioned network priority information may include different network priority lists corresponding to different access time periods. For example, see Figure 5, which is a schematic diagram of network priority information provided in this embodiment. The network priority information, as shown in Figure 5, may include PLMN list 1 corresponding to the time period t1-t2, PLMN list 2 corresponding to the time period t2-t3, etc. PLMN list 1 may indicate PLMN1 + access technology + shared network element identifier / level, PLMN2 + shared network element identifier / level; PLMN list 2 may indicate PLMN4, PLMN3 + access technology + shared network element information / level.

[0314] The UE can select the target network priority list corresponding to the current time period from the network priority lists corresponding to the different access time periods mentioned above, and then determine the target mobile communication network to access based on the network configuration information and the target network priority list.

[0315] In this way, the UE can use the aforementioned time period information to select a suitable mobile communication network from the corresponding list. If the current time point reaches the indicated time period (e.g., a new satellite arrives at the coverage area of ​​the mobile communication network, and the network elements that can be shared on different mobile communication networks on the new satellite may be different), the UE can select a new mobile communication network based on the corresponding time period and the corresponding network priority information. If the currently selected mobile communication network is different from the newly selected mobile communication network, the UE can re-initiate the registration process.

[0316] In the case of a mobile communication network that includes SNPNs, similar to EHPLMN lists and operator-controlled PLMN lists, the subscribed SNPN lists, SNPN lists controlled by credential holders, and SNPN lists carrying GINs controlled by credential holders may also carry second sharing indication information, access time period information, SNPN identification information, etc.

[0317] It is worth noting that the above-mentioned multiple lists can be used as network priority information at the same time, and priorities can also be set between the various lists. The UE can first use the list with higher priority to select the target mobile communication network. If there is no mobile communication network that can be accessed in the current list, the next list will be used to select the target mobile communication network.

[0318] In one possible implementation, the network priority information may be updated (e.g., the network element sharing situation in a new satellite is different), in which case the network priority information stored on the UE can be updated.

[0319] Specifically, the UE can obtain network priority update information, which may include the updated network priority. Then, it can use this network priority update information to update the stored network priority information.

[0320] The aforementioned network priority update information can be sent to the UE by the RAN node. For example, the UE can obtain Steering of Roaming (SOR) information, which may include network priority update information; or, it can obtain Non-Access Stratum (NAS) information, which may include network priority update information.

[0321] For example, during initial registration, mobility registration, or periodic registration, the UE may request SOR information from the UDM (which may be obtained from an external device) based on the UE context information, after the AMF confirms this. After registration, the SOR information may also be updated for the UE based on factors such as the UE's location, triggered by an update to the "Operator Controlled PLMN Selector with Access Technology". This SOR information can be sent from the AMF to the RAN node, and then from the RAN node to the UE.

[0322] The aforementioned network priority update information may also carry updated second sharing indication information.

[0323] The aforementioned second shared instruction information may include at least one of the following:

[0324] Shared network element level; shared network element identifier; shared network function.

[0325] The aforementioned NAS update information can be sent during the configuration update process for the UE. Typically, when UE parameters need to be modified, a "UE Parameter Update Command" is first sent to the UE, and the aforementioned network priority update information can be carried in the NAS update information sent during this process.

[0326] The access method provided in this embodiment includes network configuration information received by the UE, which not only contains the identification information of at least one mobile communication network, but also the first sharing indication information. This allows the UE to select a target network that suits its own needs from multiple mobile communication networks by combining the sharing status of network elements among various mobile communication networks. This improves the reliability of network selection, ensures that the user can connect to the most suitable network, and thus enhances the access experience.

[0327] In one possible implementation, if the network configuration information does not carry the first sharing indication information, the mobile communication network can be further filtered through the second sharing indication information carried by the network priority.

[0328] Referring to Figure 6, a flowchart of another access method provided in this embodiment of the disclosure is shown. The subject executing this method can be a UE, including:

[0329] S601, Receive network configuration information; the network configuration information includes the identification information of at least one mobile communication network.

[0330] S602. Based on network configuration information and network priority information, determine the target mobile communication network to be accessed from at least one mobile communication network; the network priority information is used to indicate the selection priority of each mobile communication network, and the network priority information includes second sharing indication information of at least one mobile communication network; the second sharing indication information is used to indicate the sharing information of the mobile communication network with the satellite.

[0331] In this way, the UE can select the most suitable target mobile communication network by using the second sharing indication information carried in the network priority information, even if the network configuration information does not carry the first sharing indication information.

[0332] In some embodiments, the method further includes:

[0333] Obtain network priority update information; the network priority update information includes the updated network priority information.

[0334] Update the stored network priority information based on network priority update information.

[0335] In some embodiments, obtaining network priority update information includes:

[0336] Obtain roaming guidance SOR information, which includes network priority update information; or...

[0337] Obtain update information for the non-access stratum NAS, including network priority update information.

[0338] In some embodiments, the network priority information includes a mobile communication network identifier for each mobile communication network, and at least one of the following:

[0339] Access time period; access technology information; second sharing instruction information.

[0340] In some embodiments, the second sharing indication information is indicated through access technology information; the network priority information includes the mobile communication network identifier of each mobile communication network, and at least one of the following:

[0341] Access time period; access technology information.

[0342] In some embodiments, the network priority information includes different network priority lists corresponding to different access time periods;

[0343] Based on network configuration information and network priority information, the target mobile communication network for access is determined from at least one mobile communication network, including:

[0344] Select the target network priority list corresponding to the current time period from the network priority lists corresponding to different access time periods;

[0345] Based on network configuration information and the target network priority list, the target mobile communication network for access is determined.

[0346] In some embodiments, where the mobile communication network includes a Public Land Mobile Network (PLMN), the network priority information includes an equivalent local public land mobile network (EHPLMN) list and / or an operator-controlled PLMN list.
