For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0139] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0140] The technical solutions of the embodiments of this application 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 application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0141] This application provides a network access method and apparatus that, when a terminal selects a network for accessing a terrestrial-satellite integrated network, fully considers both the parameters / status of the terrestrial-satellite integrated network and the user's computing power requirements, thereby improving the mobile connectivity capability of computing-network collaboration.

[0142] The method and apparatus are based on the same concept of the application. 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.

[0143] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR). All of these systems include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G system (5GS).

[0144] First, let's introduce the following:

[0145] The sixth-generation mobile network (6G) standard is a converged network supporting full coverage across air, space, and ground. Compared to terrestrial mobile communication networks, satellite communication utilizes high, medium, and low Earth orbit satellites to achieve wide-area or even global coverage, providing seamless communication services to users worldwide. Furthermore, for mobile communication networks, it's not just about base stations, edge computing (EC), and some core network functions being deployed to satellites; increasingly more network functions are being deployed to provide users with more services and onboard service processing.

[0146] On the other hand, the deep integration of mobile communication networks and computing power is one of the trends in the development of mobile communication networks. This is because by incorporating computing power into mobile communication networks, high-quality computing-network collaborative mobile connectivity can be provided.

[0147] With the general trend of computing and network convergence, user needs may also lead to a demand for computing power. Therefore, how to meet users' computing power needs while also meeting their communication quality requirements is a problem that needs to be considered when choosing a space-air-ground integrated network access in computing and network convergence scenarios.

[0148] Access selection algorithm for satellite network systems:

[0149] 1. Based on a single-parameter access selection algorithm:

[0150] The shortest distance access selection algorithm chooses the satellite closest to the user, as a smaller distance between the user and the satellite generally results in better signal reception. The distance-first access selection algorithm is very simple, requiring only the detection of the satellite signal's signal-to-noise ratio. The maximum elevation angle-first access selection algorithm selects the satellite with the highest elevation angle from all available satellites, ideally choosing one directly above the user for better access performance. The longest coverage time-first access algorithm effectively avoids communication instability caused by frequent handovers. The load-balanced access selection algorithm selects the satellite in the satellite network that can provide service to the user and has the most available channels, preventing the network from becoming overwhelmed by the excessive requests handled by a single satellite.

[0151] 2. Based on a multi-parameter integrated access selection algorithm:

[0152] The elevation-weighted coverage time priority scheme is an access algorithm based on elevation angle weighting. It selects a suitable satellite for access from multiple satellites by comprehensively weighting two variables: coverage time and elevation angle. The comprehensive weighted access selection algorithm, from an overall performance perspective, linearly weights the remaining number of idle channels and coverage time of the satellite, while applying non-linear weighting to the satellite elevation angle parameter. The improved comprehensive weighted access algorithm replaces the elevation angle parameter with the signal-to-noise ratio (SNR). That is, the improved algorithm weights the received signal from the satellite with the SNR of the idle channels and linearly weights the duration of coverage for the user.

[0153] 3. Access selection algorithm for multi-level satellite networks:

[0154] Based on the two types of algorithms mentioned above, a multi-layer satellite network access method was considered. In addition to the parameters mentioned above, factors such as the difference in transmission delay caused by different satellite orbital altitudes, changes in network jitter, and the different types of services requested by different users were also taken into account to design different algorithms.

[0155] Space-Ground Integration Network:

[0156] Figure 1This is a schematic diagram of a space-ground integrated network provided by related technologies, such as... Figure 1 As shown, 6G will construct an integrated, three-dimensional converged network covering air, space, land, and sea. This comprehensive air-space-ground coverage will enable information services to be provided anytime, anywhere, and in any way, allowing for various user access and applications from space-based, air-based, and land-based sources. Air-based / satellite communication offers advantages such as wide coverage, high flexibility, and strong resistance to disruption. These characteristics can be leveraged to provide satellite communication services to areas where terrestrial networks cannot be deployed or are too costly. Air-based communication via drones, aircraft, and near-space airships offers advantages such as high flexibility, low cost, and ease of deployment, providing aerial communication services to areas prone to geological disasters and uninhabited regions. For open ocean areas, maritime communication services can be provided by deploying various surface ships and floating platforms. Therefore, 6G networks need to support multiple access methods, such as space-based access via satellite, air-based access via aircraft, sea-based access via floating platforms, and terrestrial cellular network access, to meet various connection types, including mobile and satellite, and provide diverse services to individuals and industries.

[0157] Heterogeneous wireless network access selection concept:

[0158] Network access selection is a key technology in the convergence of heterogeneous wireless networks. Its main function is to control the access requests of user terminals and select a specific network to provide connection services to the user. In heterogeneous wireless networks, due to factors such as the diversity of user terminal services, the differences in wireless network channel transmission quality, and the overlap of wireless network signals, access selection algorithms are needed to ensure that users can access the most suitable network for service transmission.

[0159] Network access selection can be divided into two categories: access selection initiated by the mobile terminal for initial connection and access reselection when the mobile terminal switches to another network. The control methods for network access selection can be summarized into three types: user terminal-controlled access, network-controlled access, and user terminal-assisted network-controlled access. In the first method, the user terminal autonomously performs access selection by monitoring various network parameters and combining them with the access selection algorithm. In the second method, the network control center monitors the network status and sends the access selection result to the user terminal that initiated the access request; the control process is completed by the network end. Furthermore, in the third method, the user terminal sends the detected wireless network parameter values ​​and user personal preferences to the decision module of the network center, which then controls the user terminal's access based on the algorithm.

[0160] The network access selection process can be divided into three stages: network discovery, network selection decision, and access execution. In the first stage, the mobile user terminal needs to measure the performance parameters of each wireless network within its available signal range. In the second stage, the mobile user terminal or the network makes an access decision based on the network selection algorithm and various factors. In the third stage, based on the decision result of the second stage, the network assists the user in completing the network connection according to the communication protocol steps of the corresponding wireless network.

[0161] Computer-Network Convergence:

[0162] Related technologies highlight the concept of mobile computing networks, which are open, service-oriented computing network infrastructures built upon mobile network capabilities and infrastructure, and jointly composed of 5G Access (5G-A) network architecture and computing resources. They represent the concrete manifestation of computing networks in mobile access scenarios. Mobile computing networks tightly integrate computing and network capabilities. For low-latency interactive services such as Extended Reality (XR) and Artificial Intelligence (AI) on mobile terminals, they require, on the one hand, efficient network transmission and information exchange between the core network and the wireless access network; and on the other hand, the collaboration between cloud-edge computing power and mobile terminal computing power to meet the computing requirements for rendering, AI training, and other tasks.

[0163] The algorithms and solutions mentioned above are all based on the current state of satellite networks in related technologies. However, with the development of space-ground integrated networks and the deployment of EC and core network functions on satellites, these algorithms and solutions may no longer be suitable. With the deep integration of computing and networks and on-board processing of services, access to space-ground integrated networks must consider not only communication quality but also users' computing power requirements.

[0164] This application provides a network access method that, when a terminal selects a network for terrestrial-satellite integrated network access, fully considers both the parameters / status of the terrestrial-satellite integrated network and the user's computing power requirements, thereby improving the mobile connectivity capabilities of computing-network collaboration. The network access method provided by this application is described below:

[0165] Figure 2 This is one of the flowcharts illustrating the network access method provided in the embodiments of this application, such as...

Then, it comprehensively considers information such as network measurement results, network requirements, or service requirements to determine a suitable registration / switching target RAN for registration or switching.

[0183] Optionally, business requirements may include, but are not limited to, computing power for the access network, core network, access network and core network or third parties.

[0186] Optionally, the network control center can receive the computing power request information sent by the initial RAN, thereby obtaining the computing power demand information carried in the computing power request information, and then send the computing power request information to the computing power orchestration function based on the computing power demand information, and carry the computing power demand information in the computing power request information.

[0187] Optionally, the initial RAN can receive the request information and then send the computing power request information to the computing power orchestration function based on the computing power usage request identifier in the computing power demand information, carrying the computing power demand information.

[0189] Optionally, after the computing power orchestration function determines the location of the candidate computing power node, it can send a first computing power request response message to the initial RAN, and carry the location information of the candidate computing power node in the first computing power request response message.

[0190] For example, when the initial RAN sends computing power request information to the computing power orchestration function based on the computing power usage request identifier, it can carry information such as computing power usage requirements, network requirements, or service requirements. After receiving the computing power request information sent by the initial RAN, the computing power orchestration function can determine the location information of candidate computing power nodes based on the computing power requirement information, and then send an access response message, i.e., the first computing power request response message, to the initial RAN. The message carries the location information of candidate computing power nodes.

[0192] Optionally, the network control center can receive the response message sent by the computing power orchestration function, thereby obtaining the candidate computing power node location information carried in the response message, and then determine the candidate target RAN list based on the candidate computing power node location information.

[0193] For example, when the initial RAN sends computing power request information to the network control center based on the computing power usage request identifier, it can carry information such as computing power usage requirements, network requirements, or service requirements. The network control center can forward the computing power request information to the computing power orchestration function. After receiving the computing power request information sent by the network control center, the computing power orchestration function can determine the location information of candidate computing power nodes based on the computing power requirement information, and then send the location information of candidate computing power nodes to the network control center.

[0194] Optionally, determining the initial RAN includes:

[0199] Optionally, the selection algorithm can be based on a single-parameter access selection algorithm, a multi-parameter integrated access selection algorithm, or an access selection algorithm for multi-level satellite networks, etc. This application does not limit this.

[0200] Alternatively, in addition to using a selection algorithm, the terminal can determine the initial RAN in any way that can determine the initial RAN, and this application does not limit this.

[0201] For example, a terminal can select the RAN B closest to it as the initial RAN based on the shortest distance access selection algorithm, and then send a request message to that RAN.

[0202] For example, a terminal can select the RAN C with the largest elevation angle relative to the terminal as the initial RAN based on the maximum elevation angle priority access selection algorithm, and then send a request information to that RAN.

[0203] Optionally, when network parameter detection is performed at the network control center, since the terminal cannot obtain network parameter information, the terminal can randomly select a RAN as the initial RAN and then send a request message to that RAN.

[0204] For example, when network parameter detection is performed at the network control center, the terminal can select RAN D, RAN E, or RAN F as the initial RAN and then send a request message to that RAN.

[0205] Optionally, the network access method further includes:

[0206] Receive a first access response message sent by the initial RAN, the first access response message carrying a target RAN list, the target RAN list being determined based on candidate computing node location information;

[0208] Optionally, after receiving the first access response message sent by the initial RAN, the terminal can select a RAN from the target RAN list as the target RAN based on the detection results of network parameters, network requirements, or its own service requirements. The selection method may include, but is not limited to, a single-parameter access selection algorithm, a multi-parameter integrated access selection algorithm, or an access selection algorithm for multi-level satellite networks. Then, the terminal sends a registration request message to the target RAN to register the target RAN into the network.

[0209] For example, if the target RAN list includes RAN A, RAN B, and RAN C, the terminal can select RAN B, which is the closest to the terminal in the RAN list, as the target RAN based on the shortest distance access selection algorithm, and then send a registration request message to RAN B to register RAN B into the network.

[0211] For example, if the initial RAN F receives a list of target RANs, which includes RAN A, RAN B, and RAN F, then RAN F can initiate a registration request to the core network to complete the registration process.

[0212] Optionally, if the initial RAN fails to complete the registration process based on the access response message, the initial RAN may send a first access response message to the terminal, including a rejection reason value, and carrying a list of target RANs in the rejection reason value.

[0213] For example, when RAN G initially receives a target RAN list that includes RAN A, RAN B, and RAN F, and since RAN G is not in the list, RAN G can send a first access response message to the terminal, including a rejection reason value and carrying the target RAN list in the rejection reason value.

[0214] Optionally, before sending the request information, the network access method further includes:

Then, it sends a second access response message to the terminal, carrying RAN C in the second access response message.

After receiving the access request response message and obtaining the execution registration instruction information carried in the access request response message, the initial RAN can initiate a registration request to the core network to complete the terminal's access registration process.

[0326] For example, if the initial RAN is RAN A, and the target RAN list includes RAN A, RAN B, and RAN C, the network control center can select RAN A, which is closest to the terminal in the RAN list, as the target RAN based on the shortest distance access selection algorithm. Then, it sends an access request response message to RAN A, carrying registration instruction information in the access request response message.

[0327] Optionally, if the initial RAN is not the target RAN determined by the network control center, the network control center may send a registration request message to the selected target RAN to complete the terminal's access registration process.

Since RAN A is not the target RAN selected by the network control center, the network control center can send a registration request message to RAN B to complete the terminal's access registration process.

[0341] For example, if the target RAN list contains RAN A, RAN B, and RAN C, the network control center can select RAN C, which is closest to the terminal in the RAN list, as the RAN that best meets the above requirements, based on the detection results of network parameters, network requirements, and service requirements, using the shortest distance access selection algorithm. Then, it sends a second access response message to the terminal, carrying RAN C. After receiving the second access response message, the terminal can send a handover request message to RAN C, carrying the information of RAN C in the handover request message, to complete the RAN handover.

[0342] Optionally, the network access method further includes:

This request message includes a computing power usage request identifier, computing power type / application type, computing power size, and computing power usage duration. The computing power node type includes computing power from the access network, core network, access network and core network, third parties, and combinations thereof.

[0399] Step 2: The computing power orchestration function determines the location information of candidate computing power nodes based on the information carried. It then sends a first computing power request response message to the initial RAN, which carries the location information of the candidate computing power nodes. The initial RAN then responds to the first computing power request response message. If the registration process can be completed, it initiates a registration request to the core network to complete the registration process, thus omitting steps 3 and 4.

[0416] Step 5: If the initial RAN belongs to the target RAN, the network control center returns an access request response message to the initial RAN, carrying information such as the registration identifier. Then, based on the access request response message, the initial RAN initiates a registration request to the core network to complete the registration process, thus omitting step 5b. If not, step 5b is executed.

[0417] Step 5b: The network control center sends a registration request message to the target RAN to register with the network.
