[0032] Figure 1 is a flow chart of an information processing method of a terminal device according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0033] Step S102: Acquire priority information of the converged network system.

[0034] In the technical solution provided in the above step S102 of the embodiment of the present invention, the fused network system may also be referred to as a multi-layer heterogeneous network, a satellite-ground network fusion, or a multi-layer heterogeneous network integrating the earth and the sky, and the fused network system may include different network systems. The network system may also be referred to as a network layer. Different network systems include at least a ground network system, a first satellite network system, and a second satellite network system. The ground network system may also be referred to as a ground communication system, for example, a ground cellular communication network, or a cellular ground network, which may be represented by a network A in the embodiment of the present invention. The coverage of the first satellite network system is greater than the coverage of the second satellite network system. The first satellite network system may be a high-orbit satellite network system, which may be represented by a network B in the embodiment of the present invention. The second satellite network system may be a low-orbit satellite network system, which may be represented by a network C in the embodiment of the present invention. Priority information may be used to indicate the order in which terminal devices access different network systems, which may also be referred to as a priority order. The terminal device may also be referred to as a terminal device, for example, a mobile phone.

[0035] It should be noted that the network system included in the above-mentioned fusion network system is only for illustration and is not specifically limited here. As long as it is a network system capable of multi-layer heterogeneous network fusion, it is within the protection scope of the embodiments of the present invention.

[0036] In this embodiment, if the terminal device has a demand to connect to the network system, the priority information of the converged network system can be obtained.

[0037] Optionally, before performing information processing on the terminal device, a corresponding priority order may be set in advance for each network system in the converged network system according to requirements to obtain corresponding priority information.

[0038] Optionally, when the terminal device needs to access the network system, the above-mentioned preset priority information can be obtained, for example, the terminal device can be turned on and the preset access priority can be confirmed.

[0039] For example, after the terminal device is turned on, it can search for networks on supported frequency bands according to the preset access priority information. The above preset access priorities are pre-configured based on network coverage and capacity requirements, and are usually solidified in the system settings of the terminal device. The priority setting helps the terminal device quickly find the most suitable network for access to meet its service needs. For example, the terrestrial cellular network (A network) usually has better capacity and lower latency, so it has the highest priority; while the high-orbit satellite network (B network) and the low-orbit satellite network (C network) are selected later based on coverage and mission requirements.

[0040] It should be noted that the above process and method for obtaining priority information, as well as the priority order of each network system in the priority information are only examples and are not specifically limited here.

[0041] Step S104, when the terminal device is connected to the ground network system based on the priority information and the attribute information of the terminal device, the ground network configuration information of the ground network system is used to interact with the terminal device.

[0042] In the technical solution provided in the above step S104 of the embodiment of the present invention, the ground network configuration information can also be referred to as the resources of the ground network system, for example, it can be the ground cellular spectrum resources. The attribute information of the terminal device may include location information, which is used to indicate the location of the terminal device, and may also include information such as the working frequency bands of each network system supported by the terminal device, that is, a list of frequency bands supported by the terminal device, and may also include task requirements, such as data rate, delay requirements, etc. The above information is crucial for the network side to decide which network system the terminal device is to access. The attribute information of the terminal device can be used to indicate the performance of the terminal device, and may also be referred to as the terminal device capability reporting information.

[0043] It should be noted that the above-mentioned attribute information is only for illustration and is not specifically limited here. As long as the attribute information can be used to determine which network system the terminal device should currently access, it is within the protection scope of the embodiments of the present invention.

[0044] In this embodiment, after obtaining the priority information of the converged network, it is possible to determine which network system in the converged network system the terminal device should currently access based on the priority information and the attribute information of the terminal device. If it is determined that the ground network system needs to be accessed, the terminal device can be controlled to access the ground network system. At this time, if the terminal device issues an interaction request, the ground network system can be used to process the interaction request to achieve information interaction between the ground network system and the terminal device.

[0045] Optionally, once the network side determines the network layer that the terminal device should access based on the above analysis, it will guide the terminal device to perform network access or frequency switching by sending necessary switching information and instructions, such as frequency point, beam identification, etc.

[0046] Alternatively, when the terminal device sends an interactive request through the ground network system, the ground network can use its own high capacity and low latency characteristics to efficiently process these requests. The ground network usually has a denser base station deployment and stronger signal processing capabilities, which gives it an advantage in handling broadband tasks.

[0047] In an embodiment of the present invention, through the pre-configured priority information of the network system and the intelligent analysis of the attribute information of the terminal device, the network resource allocation can be dynamically adjusted to avoid the waste of spectrum resources. Ensure that users can enjoy appropriate network services at any location, whether it is a broadband task with a high data rate or a narrowband task with a low data rate. Through reasonable frequency sharing and switching strategies, the risk of mutual interference between multi-layer networks can be effectively reduced, and the stability and reliability of the network can be improved. The collaborative work of ground cellular networks, high-orbit and low-orbit satellite networks can achieve almost dead-angle network coverage worldwide, especially in remote areas and at sea, where traditional networks are difficult to reach.

[0048] Step S106, when the terminal device is connected to the first satellite network system based on the priority information and the attribute information, if the interaction request of the terminal device is a first target interaction request, information interaction is performed with the terminal device using the first configuration information of the first satellite network system.

[0049] In the technical solution provided in the above step S106 of the embodiment of the present invention, the interaction request can be used to represent a task initiated by a terminal device or a task request received. The first target interaction request can be an interaction request requiring less bandwidth, which can also be called a narrowband request or a narrowband task request, such as voice or short message. The first configuration information can be a satellite mobile task spectrum resource. A narrowband task request generally refers to a communication task that requires a lower data transmission rate, such as voice calls, short message services, and some low-speed data transmission tasks. The characteristics of a narrowband task are a lower data transmission rate and a narrow bandwidth.

[0050] It should be noted that the above narrowband tasks are only examples and are not specifically limited here. As long as they are communication tasks that need to be processed in the first satellite network system, they are within the protection scope of the embodiments of the present invention.

[0051] In this embodiment, after the priority information of the fused network is obtained, it is possible to determine which network system in the fused network system the terminal device should currently access based on the priority information and the attribute information of the terminal device. If it is determined that the first satellite network system needs to be accessed, the terminal device can be controlled to access the first satellite network system. At this time, if the terminal device issues an interaction request, it can be determined whether the interaction request is a first target interaction request. If so, the first satellite network system can be directly used to process the interaction request to achieve information interaction between the first satellite network system and the terminal device.

[0052] Optionally, when the terminal device sends an interaction request, the network side can determine whether the request is a first target interaction request. The first target interaction request generally refers to broadband tasks that have low requirements for bandwidth or delay. If it is a first target interaction request, the terminal device can be controlled to establish a connection with the first satellite network system, and the first configuration information in the first satellite network system can be used to process the first target interaction request.

[0053] Step S108: If the interaction request is a second target interaction request, the terminal device is connected to the second satellite network system, and information is interacted with the terminal device using the second configuration information of the second satellite network system and the first configuration information.

[0054] In the technical solution provided in the above step S108 of the embodiment of the present invention, the bandwidth required by the second target interaction request is greater than the bandwidth required by the first target interaction request. The second target interaction request can also be called a broadband task request. The difference between a narrowband task request and a broadband task request is mainly reflected in the data transmission rate, the task type and the occupied bandwidth. A broadband task request refers to a communication task that requires a higher data transmission rate, such as Internet browsing, video streaming, online games, file downloads, etc. The characteristics of a broadband task are a higher data transmission rate and a wider bandwidth. The second configuration information can be used to indicate the frequency band support capability of the second satellite network system itself.

[0055] In the embodiment of the present invention, the network layer to which the terminal device accesses can be determined according to the type of task request (narrowband or broadband) to achieve efficient resource utilization and minimize interference. For example, in a satellite-ground fusion network, narrowband tasks can be directly processed on the high-orbit satellite network, while broadband tasks require the low-orbit satellite network to reuse the spectrum resources of the ground network or the high-orbit satellite network to provide services.

[0056] In this embodiment, after the priority information of the fused network is obtained, it is possible to determine which network system in the fused network system the terminal device should currently access based on the priority information and the attribute information of the terminal device. If it is determined that the second satellite network system needs to be accessed, the terminal device can be controlled to access the first satellite network system. At this time, if the terminal device issues an interaction request, it can be determined whether the interaction request is a second target interaction request. If so, the first satellite network system can be switched to the second satellite network system. The interaction request is processed using the second configuration information in the second satellite network system and the received first configuration information to realize information interaction between the second satellite network system and the terminal device.

[0057] Optionally, when the terminal device sends an interaction request, the network side needs to determine whether the request is a second target interaction request. The second target interaction request usually refers to broadband tasks that have high requirements on bandwidth or delay, such as high-speed data transmission.

[0058] Optionally, if the interaction request is determined to be a second target interaction request, and the network side decides that the terminal device should access the low-orbit satellite network, then the high-orbit satellite network can send the first configuration information to the low-orbit satellite network. The first configuration information can be necessary system configuration information, such as a reusable spectrum resource pool and terminal device location information. Based on this information, the low-orbit satellite network selects appropriate frequencies and beams, and configures corresponding second configuration information, which can be carrier and beam resources. At this time, the low-orbit satellite network is selected to establish a connection with the terminal device to realize the carrying of broadband tasks.

[0059] In the embodiments of the present invention, by frequency sharing, in particular by utilizing the idle spectrum resources of the ground network and the high-orbit satellite network, the spectrum utilization efficiency of the low-orbit satellite network is improved to support higher-speed tasks. Based on signal perception and frequency resource pool management, interference between multiple layers of networks is effectively avoided, ensuring the reliability and stability of the network. Seamless switching between different network systems is achieved, ensuring the continuous communication experience of users in remote areas or under different network coverage.

[0060] In the technical solution provided by the above steps S102 to S108 of the embodiment of the present invention, if the terminal device has a demand to be connected to the network system, the priority information of the fusion network system can be obtained, and the order in which the terminal device is connected to each network system in the fusion network system can be determined by the priority information. The network system that the terminal device needs to be connected to can be determined according to the above priority information and the attribute information of the terminal device itself. If the network system accessed is a ground network system, the ground network configuration information in the ground network system can be used to interact with the terminal device, that is, the terminal device accesses the ground network system, and if the terminal device issues an interaction request, the ground network configuration information can be used to process the above interaction request. If the network system accessed is the first satellite network system, it can be detected whether the terminal device initiates an interaction request. If it is detected that the terminal device initiates an interaction request, the request type of the interaction request can be determined, that is, whether the interaction request is a first target interaction request or a second target interaction request. If it is a first target interaction request, the interaction request can continue to be processed in the first satellite network system using the first configuration information. If it is a second target interaction request, it can be switched to the second satellite network system. At this time, the second satellite network system can receive the first configuration information sent by the first satellite network system, and then use its own second configuration information and the received first configuration information to process the interaction request.

[0061] In this embodiment, the ground network configuration information, the first configuration information, and the second configuration information can be comprehensively planned, so that when processing requests requiring a large bandwidth, other configuration information can be reused to increase the availability of configuration resources, thereby achieving the purpose of improving resource utilization efficiency, reducing interference between different network systems in the converged network system, and improving the reliability and overall performance of the network system. This achieves the technical effect of improving the information processing efficiency of the terminal device and solves the technical problem of low information processing efficiency of the terminal device.

[0062] The embodiment of the present invention is described in detail below in combination with the above steps.

[0063] As an optional embodiment, the first configuration information includes at least frequency resources, wherein, if the interaction request is a second target interaction request, the terminal device is connected to the second satellite network system, and information interaction is performed with the terminal device using the second configuration information of the second satellite network system and the first configuration information, including: if the interaction request is a second target interaction request, and the terminal device is connected to the second satellite network system, based on the attribute information and the load information of the frequency resources, the target frequency resources are screened out from the frequency resources, wherein the target frequency resources are frequency resources that need to be sent to the second satellite network system; and information interaction is performed with the terminal device using at least the second configuration information and the target frequency resources.

[0064] In this embodiment, when the terminal device is connected to the second satellite network system and the second configuration information and the first configuration information of the second satellite network system are used to interact with the terminal device, the target frequency resource can be screened out from the frequency resources in the first configuration information based on the attribute information and the load information of the frequency resource. At least the second configuration information and the target frequency resource are used to interact with the terminal device. The load information is used to indicate the load of the corresponding frequency resource in the first satellite network system. The target frequency resource can be a frequency resource that needs to be sent to the second satellite network system. The target frequency resource can also be called a sharable spectrum resource, such as a spectrum resource pool or a spectrum sharing resource pool.

[0065] Alternatively, under broadband mission requests, the key to achieving spectrum resource sharing is to effectively manage and coordinate spectrum usage between different networks to minimize the interference caused and maximize resource utilization.

[0066] Optionally, when a terminal device initiates a broadband task request, the high-orbit satellite network system can determine the spectrum resource pool M (frequency resource pool) that the terminal device can access in the low-orbit satellite network system at its current location based on the capability information reported by the terminal device, such as the supported frequency band list, location information, etc., the carrier frequency and beam planning of the high-orbit satellite network system itself, and the load of the task. The spectrum resource pool M is actually a subset of the spectrum resources available to the ground network system and the high-orbit satellite network system, ensuring that the low-orbit satellite network system can reuse these resources, but at the same time avoiding interference to the ground network system or the high-orbit satellite network system.

[0067] Optionally, after determining the spectrum resource pool, the high-orbit satellite network system can send necessary system configuration information to the low-orbit satellite network system in one or more ways, including the spectrum resource pool M, terminal device location, etc. After receiving the above information, the low-orbit satellite network system will use a specific algorithm to optimize the frequency point and beam in combination with its own frequency band support capabilities, and make configuration decisions for carrier and beam resources. In other words, the low-orbit satellite network system will consider how to use the resources in the spectrum resource pool M, while ensuring coordination with the high-orbit satellite network system to avoid mutual interference during frequency reuse.

[0068] As an optional embodiment, before at least using the second configuration information and the target frequency resources to interact with the terminal device, the method also includes: controlling the first satellite network system to at least send the target frequency resources to the second satellite network system, and controlling the first satellite network system to send switching notification information to the terminal device; in response to a switching instruction corresponding to the switching notification information, controlling the terminal device to switch from the first satellite network system to the second satellite network system; using at least the second configuration information and the target frequency resources to interact with the terminal device, including: in response to the terminal device accessing the second satellite network system, controlling the second satellite network system to interact with the terminal device in a connected state by at least using the second configuration information and the target frequency resources.

[0069] In this embodiment, before exchanging information with the terminal device using at least the second configuration information and the target frequency resource, the first satellite network system may be controlled to at least send the target frequency resource to the second satellite network system. The first satellite network system may be controlled to send a switching notification message to the terminal device. Based on the switching instruction corresponding to the switching notification message, the terminal device may be controlled to switch from the first satellite network system to the second satellite network system.

[0070] Optionally, in the process of performing information interaction with the terminal device by at least using the second configuration information and the target frequency resource, if the terminal device is connected to the second satellite network system, the second satellite network system can be controlled to be in a connected state, and in the connected state, at least the second configuration information and the target frequency resource are used to process the interaction request to perform information interaction with the terminal device. The switching notification message may be the necessary inter-frequency switching information and instructions sent by the first satellite network system to the terminal device. The switching instruction may be used for inter-frequency switching from the first satellite network system to the second satellite network system. The connection state may be a Radio Resource Control connection (RRC) state, in which data transmission and more complex service requests and management may be performed.

[0071] Optionally, the high-orbit satellite network system can send necessary first configuration information to the low-orbit satellite network system, so that the low-orbit satellite network system can optimize the frequency point and beam according to current conditions and needs. The above process is a key step in realizing multi-layer network frequency sharing and intelligent network selection of terminal devices.

[0072] Optionally, the high-orbit satellite network system determines a reusable frequency resource pool based on the capability information reported by the terminal device, such as the supported frequency band list and location information, combined with the carrier frequency / beam planning of its own network, such as the configured frequency of the beam where the current terminal device is located, the frequency planning of adjacent beams, and the load situation. The frequency resource pool contains the frequency resources of the ground network system and the high-orbit satellite network system as a frequency option that may be reused by the low-orbit satellite network system.

[0073] Optionally, the location information of the terminal device is crucial for the optimization of frequency resources. The beam planning of the low-orbit satellite network system is usually more sophisticated, which can use frequency resources more efficiently and avoid interference with existing networks on the ground. With accurate terminal device location information, the low-orbit satellite network system can determine the appropriate beam where the terminal device is located, thereby selecting the appropriate frequency resources.

[0074] Optionally, after receiving the information transmitted by the high-orbit satellite network system, the low-orbit satellite network system optimizes the frequency point and beam through an algorithm based on the characteristics and capabilities of its own system, such as frequency band support capability, beam planning, network load, etc. To ensure that the reused frequency resources will not cause excessive interference to the ground network or other satellite networks, spectrum efficiency and interference ratio can be used as decision-making indicators.

[0075] Optionally, the low-orbit satellite network system can select appropriate beam resources based on the terminal device location information and network requirements, and can consider factors such as beam coverage, capacity, and signal-to-noise ratio. The low-orbit satellite network system can also analyze the current load of the network and the specific task requirements of users, such as data rate and latency, to ensure that resource allocation meets the balance between user experience and network efficiency.

[0076] Optionally, after completing the decision on the preferred frequency and beam, the low-orbit satellite network system informs the high-orbit satellite network system of the decision result, including the selected frequency resources and beam information. The high-orbit satellite network system then sends frequency switching information and instructions to the terminal device based on the above information, instructing the terminal device to switch to the low-orbit satellite network system and establish an RRC connection to start the transmission of the broadband task.

[0077] In the embodiment of the present invention, through frequency sharing and beam optimization, spectrum resources can be effectively utilized to improve the overall capacity and coverage of the network without affecting the normal services of the ground network and the high-orbit satellite network. The low-orbit satellite network system can intelligently select the frequency points and beams that have the least interference with the existing network based on the information provided by the high-orbit satellite network system and its own algorithms, thereby reducing interference problems between networks and ensuring reliable communication of the network. For terminal devices that require high-speed data tasks, providing services through the frequency resource pool of the low-orbit satellite network system can significantly improve data transmission rate and latency indicators and improve user experience. Frequency sharing between multi-layer networks and intelligent network selection of terminal devices realize the coordinated optimization of satellite-to-ground networks and high- and low-orbit satellite networks, and improve the overall performance and efficiency of the network.

[0078] In summary, the above method is the key to realizing frequency resource sharing of multi-layer heterogeneous networks and intelligent network selection of terminal devices, and plays an important role in improving network spectrum efficiency, optimizing user experience and reducing interference risks.

[0079] As an optional embodiment, if the interaction request is a second target interaction request, based on the attribute information and the load information of the frequency resources, the target frequency resources are screened out from the frequency resources, including: if the interaction request is a second target interaction request, based on the frequency information in the attribute information, the first frequency resource is screened out from the frequency resources, wherein the frequency information is used to indicate the frequency under the beam where the terminal device is located, and the first frequency resource is a frequency resource adapted to the terminal device; the first frequency resource whose load information is lower than the load information threshold is determined as the target frequency resource.

[0080] In this embodiment, in the process of screening out the target frequency resource from the frequency resources based on the attribute information and the load information of the frequency resource, the first frequency resource can be screened out from the frequency resources based on the frequency information in the attribute information. The first frequency resource whose load information is lower than the load information threshold can be determined as the target frequency resource. The frequency information can be used to indicate the frequency under the beam where the terminal device is located. The first frequency resource can be a frequency resource adapted to the terminal device. The load information threshold can indicate a critical threshold of whether the load is low. If the load information is lower than the load information threshold, the corresponding first frequency resource can be a frequency resource with a lower load.

[0081] Optionally, the high-orbit satellite network system determines the frequency resource pool M that can be reused by the terminal device to access the low-orbit satellite network system based on the capability information reported by the terminal device, the current frequency / beam planning, and the task load. The above process is based on the principle of minimizing interference, aiming to improve the efficiency of spectrum resource utilization while ensuring that interference between networks is minimized.

[0082] Optionally, the terminal device can provide the high-orbit satellite network system with a list of frequency bands of the ground cellular network system it supports, as well as the current location information of the terminal device. The above information can be used to enable the high-orbit satellite network system to determine the communication capabilities and geographical location of the terminal device, and then determine which frequency resources can be reused without causing interference to the ground cellular network system.

[0083] Optionally, the high-orbit satellite network system can take into account the frequency configuration of the beam where the current terminal device is located, as well as the frequency planning of surrounding beams. This is because satellite networks usually use beam coverage, different beams cover different areas, and there may be frequency overlap between beams. Based on beam planning, the high-orbit satellite network system can determine which frequencies are available at the current terminal device location, while avoiding unnecessary interference with adjacent beams.

[0084] Optionally, the high-orbit satellite network system can also consider its own load. If a specific frequency or beam of the high-orbit satellite network system is close to saturation, then allocating these frequency resources to the low-orbit satellite network system for reuse may reduce the service quality of the high-orbit satellite network system. Therefore, the high-orbit satellite network system can give priority to frequency resources with lower loads to ensure the efficient and stable operation of the entire network.

[0085] Optionally, after comprehensively considering the above factors, the high-orbit satellite network system can determine a frequency resource pool, which can include frequency bands in the ground cellular network system and the high-orbit satellite network system that can be reused by the low-orbit satellite network system. The determination of the frequency resource pool M is based on the principle of minimizing interference and optimizing network capacity, ensuring that spectrum resources are maximized without damaging the quality of existing network services.

[0086] Optionally, the characteristics of the frequency resource pool determine the types of missions and service quality it can support. For example, if the frequency resources contained in the frequency resource pool have good propagation characteristics or less interference, then it may be more suitable for carrying high-speed data missions. Conversely, if the resources contained in the frequency resource pool are susceptible to interference due to geographical environment or frequency planning, then it may be more suitable for carrying low-speed data or voice missions. The key to the above mechanism is that by intelligently analyzing and allocating frequency resources, efficient collaboration between satellite-ground and high- and low-orbit satellite networks is achieved, which not only improves the utilization rate of spectrum resources, but also ensures the service quality and user experience between networks. It is an important part of frequency sharing and resource optimization in satellite-ground and high- and low-orbit integrated networks.

[0087] Optionally, the network side of the high-orbit satellite network system can send frequency switching information and instructions to the terminal device. The above process is the key to achieving smooth switching of broadband task requests between multi-layer networks.

[0088] Optionally, in a broadband mission request scenario, the network side of the high-orbit satellite network system can determine the reusable frequency resource pool based on the terminal device capability reporting information, the carrier frequency and beam planning of the high-orbit satellite network system, and the current mission load of the high-orbit satellite network system. The high-orbit satellite network system sends the frequency resource pool and terminal device location information to the low-orbit satellite network system. The low-orbit satellite network system uses an algorithm to optimize the frequency point and beam based on its own frequency support capability and resource pool M, and completes the configuration decision of the carrier and beam resources. The above process aims to maximize the utilization efficiency of network resources while minimizing interference to ground networks and other satellite networks.

[0089] Optionally, the network side of the high-orbit satellite network system generates an inter-frequency switching instruction according to the frequency configuration decision of the low-orbit satellite network system. The instruction contains necessary information, such as the frequency and beam identification (such as ID) of the low-orbit satellite network system, to guide the terminal device on how to switch from the high-orbit satellite network system to the low-orbit satellite network system.

[0090] Optionally, after the terminal device receives the inter-frequency switching instruction from the network side of the high-orbit satellite network system, it can perform measurements on the inter-frequency to determine the target cell in the low-orbit satellite network system. The terminal device selects a target cell with suitable signal quality in the low-orbit satellite network system based on the measurement results to ensure that the broadband task request can be met after the switch.

[0091] Optionally, the terminal device can send a switching request to the network side of the high-orbit satellite network system, and then according to the instructions of the high-orbit satellite network system, the terminal device performs heterogeneous frequency switching, switching from the high-orbit satellite network system to the target cell of the low-orbit satellite network system.

[0092] Optionally, after completing the inter-frequency handover, the terminal device can establish an RRC connection on the target cell of the low-orbit satellite network system to prepare for transmitting broadband mission data. The establishment of the RRC connection ensures the communication channel between the terminal device and the low-orbit satellite network system, providing the necessary control information and resources for data transmission.

[0093] In an embodiment of the present invention, through the heterodyne switching mechanism, the terminal device can smoothly switch between multiple layers of networks and make full use of the spectrum resources of the satellite-to-ground network, especially in remote areas or hot spots. The frequency resources of the ground network system and the high-orbit satellite network system are reused by the low-orbit satellite network system to improve the efficiency of spectrum utilization. The network side optimizes the frequency points and beams through intelligent algorithms to avoid interference between multiple layers of networks and ensure the continuity and stability of network services. Broadband task requests can be responded to and processed quickly, and users in remote areas can enjoy high-quality broadband services, which improves the overall network experience of users. The low-orbit satellite network reuses the frequency resources of the ground cellular network and the high-orbit satellite network in hot spots, effectively enhancing the capacity and coverage of the network, especially in areas that are difficult to cover by the ground network.

[0094] In summary, under the broadband task request, through pre-configured network priority, reporting of terminal device capabilities and location information, spectrum resource coordination between systems, and intelligent frequency switching of terminal devices, effective utilization of spectrum resources is achieved, network coverage and capacity are improved, interference risks are reduced, and user experience is optimized.

[0095] As an optional embodiment, the method further includes: in response to completing the processing of the interaction request by using the second satellite network system, controlling the terminal device to switch from the second satellite network system to the first satellite network system.

[0096] In this embodiment, after the second satellite network system is used to complete the processing of the interactive request, the terminal device may be controlled to switch from the second satellite network system back to the first satellite network system.

[0097] Optionally, after the broadband task is completed, that is, once it is determined that the broadband task on the terminal device is completed and the terminal device detects the end of data transmission, the terminal device will enter an idle state, wherein the idle state is a low-power mode, and the terminal device will disconnect from the network, but still keep monitoring the network to receive paging messages or new interaction requests. In the idle state, the terminal device can start preparing for inter-frequency switching.

[0098] Optionally, in the Idle state, the terminal device may start to measure signal quality on the frequency bands of the ground network system and the first satellite network system. According to the measurement results and pre-configured priority information, the terminal device selects the returned high-orbit satellite network system.

[0099] Optionally, the terminal device can send a switching request to the currently connected low-orbit satellite network system. The low-orbit satellite network system can decide whether to allow the switching based on the terminal device request and the network conditions of the high-orbit satellite network system, such as the load of the high-orbit satellite network system, and send a switching instruction to the terminal device. The terminal device disconnects from the low-orbit satellite network system according to the received switching instruction, and then searches for and connects to the appropriate frequency and beam of the high-orbit satellite network system. If the switching is successful, the terminal device can stay on the high-orbit satellite network system, re-enter the Id le state, and wait for the next interaction request or paging message.

[0100] In the embodiment of the present invention, through the above-mentioned inter-frequency switching mechanism, the terminal device can flexibly switch between multiple layers of networks to utilize appropriate network resources and avoid unnecessary interference, thereby improving the overall performance of the network and user experience. At the same time, this mechanism helps to balance the load of each layer of the network and avoid a situation where a certain network is overcrowded while other network resources are idle.

[0101] As an optional embodiment, step S106, when the terminal device is connected to the first satellite network system based on the priority information and the attribute information, if the interaction request of the terminal device is a first target interaction request, using the first configuration information of the first satellite network system to interact with the terminal device, including: when the terminal device is connected to the first satellite network system based on the priority information and the attribute information, if the interaction request of the terminal device is a first target interaction request, controlling the first satellite network system to be in a connected state, and using the first configuration information to interact with the terminal device; the method also includes: in response to completing the processing of the interaction request using the first satellite network system, controlling the first satellite network system to be in an idle state.

[0102] In this embodiment, when the terminal device accesses the first satellite network system, if the interaction request of the terminal device is a first target interaction request, the first configuration information of the first satellite network system can be used to control the first satellite network system to be in a connected state, and in the connected state, the first configuration information can be used to process the interaction request to interact with the terminal device. After the first satellite network system completes the processing of the interaction request, the first satellite network system can be controlled to be in an idle state.

[0103] Optionally, when the terminal device initiates a narrowband mission request, such as voice or short message service, the terminal device will establish an RRC connection on the first satellite network system. RRC connection establishment is a key step in establishing a communication link between the terminal device and the network system. The above process can ensure that the terminal device can exchange control information with the network, such as signaling, mobility management, wireless resource configuration, etc. Under the narrowband mission request, RRC connection establishment mainly focuses on ensuring basic connection quality and communication security without requiring excessive spectrum resources.

[0104] Optionally, when the terminal device sends a task request, the network side will analyze the type of request to determine whether it is a narrowband task. If it is a narrowband task, the network side will determine whether the terminal device establishes an RRC connection on the high-orbit satellite network system based on the pre-configured priority and resource status, for example, considering the current task load, the utilization of spectrum resources, the location information of the terminal device, etc., to ensure the effective allocation of resources.

[0105] In an embodiment of the present invention, by giving priority to using the spectrum resources of the high-orbit satellite network when requesting a narrowband task, the utilization rate of the spectrum resources can be improved and the spectrum dependence on low-orbit satellites and ground cellular networks can be reduced. In addition, due to the wide-area coverage characteristics of the high-orbit satellite network, this method can also ensure that terminal devices can stably perform narrowband task communications in remote areas or areas with poor ground network coverage. In summary, the processing strategy for narrowband tasks in the above method is to reasonably allocate and utilize the spectrum resources in the satellite-ground fusion network while ensuring the quality of service, thereby improving the overall performance of the network and user experience.

[0106] As an optional embodiment, the method also includes: in response to receiving an interaction request, when the terminal device is connected to the first satellite network system based on priority information and attribute information, obtaining the data volume and delay information of the interaction information indicating the interaction in the interaction request, wherein the delay information is used to indicate the allowed delay length of the interaction information; in response to the data volume being less than or equal to a data volume threshold, and the delay information being less than or equal to a delay information threshold, determining that the interaction request is a first target interaction request; in response to the data volume being greater than the data volume threshold, and / or the delay information being greater than the delay information threshold, determining that the interaction request is a second target interaction request.

[0107] In this embodiment, when the terminal device is connected to the first satellite network system based on the priority information and the attribute information, when an interaction request is received, the data volume and delay information of the interaction information indicated in the interaction request can be obtained. If the data volume is less than or equal to the data volume threshold, and the delay information is less than or equal to the delay information threshold, the interaction request can be determined to be a first target interaction request. If the data volume is greater than the data volume threshold, and / or the delay information is greater than the delay information threshold, the interaction request can be determined to be a second target interaction request. Among them, the delay information can be used to indicate the acceptable delay length of the interaction information, for example, it can be delay sensitivity.

[0108] Optionally, when the terminal device is resident in a high-orbit satellite network system, a network access strategy may be determined according to characteristics of the interaction request to achieve frequency sharing and interference avoidance among multiple layers of networks.

[0109] Optionally, when the terminal device resides in the high-orbit satellite network system, it can initiate an interactive request, such as sending data, video streaming, or high-speed data download, or the network side may initiate services to the terminal device through paging, such as receiving emails, updating software, etc. In either case, the network side of the high-orbit satellite network system can identify and classify the above requests to determine whether they are narrowband tasks (such as voice, short messages) or broadband tasks (such as high-speed data transmission).

[0110] Optionally, for interactive requests, the network side can evaluate their data volume requirements and delay sensitivity. Broadband tasks usually require larger data bandwidth and lower transmission delay, while narrowband tasks require smaller data bandwidth and are less sensitive to delay. By analyzing the above data volume requirements and delay sensitivity, it is possible to intelligently decide which interactive requests can be processed within the high-orbit satellite network system and which can be transferred to the frequency resource pool of the low-orbit satellite network system for processing.

[0111] Optionally, based on the analysis of the interactive request, the network side of the high-orbit satellite network system will make a decision. If the request belongs to a narrowband task, it will be processed inside the high-orbit satellite network system, that is, a connection will be established on the high-orbit satellite network, because the network system can well support services such as voice and short messages, and does not require additional frequency resources or complex switching processes.

[0112] As an optional embodiment, step S102, obtaining priority information of the converged network system, includes: in response to the terminal device being in a network searching state, obtaining priority information.

[0113] In this embodiment, in the process of acquiring the priority information of the converged network system, if the terminal device is in a network searching state, the priority information can be acquired.

[0114] Optionally, the above process is the starting point of the entire terminal device network selection method based on multi-layer network frequency sharing. After being turned on, the terminal device can search for the network and select the network system to access based on the preset network access priority.

[0115] Optionally, when the terminal device is turned on, it can search for an available network to connect to so as to provide communication services. The above process can be a network search, that is, a network search state.

[0116] Optionally, the terminal device receives preset network access priority information during the network search process. The above priority information is pre-configured and may be based on factors such as network coverage, service quality, network type (eg, terrestrial cellular, satellite), etc.

[0117] As an optional embodiment, the priority of the ground network system is greater than the priority of the first satellite network system, and the priority of the first satellite network system is greater than the priority of the second satellite network system, wherein the method further includes: when the terminal device is in a network searching state, searching for the ground network system according to the frequency band of the ground network system supported by the terminal device; in response to searching the ground network system, controlling the terminal device to access the ground network system; in response to not searching the ground network system, searching for the first satellite network system according to the frequency band of the first satellite network system supported by the terminal device; in response to searching the first satellite network system, controlling the terminal device to access the first satellite network system.

[0118] In this embodiment, taking the case where the priority of the ground network system is greater than the priority of the first satellite network system, and the priority of the first satellite network system is greater than the priority of the second satellite network system, that is, ground network system A>first satellite network system B>first satellite network system C as an example, when the terminal device is in a network search state, the ground network system can be searched with the frequency band of the ground network system supported by the terminal device. If the ground network system is searched, a connection between the terminal device and the ground network system can be established. If the ground network system is not searched, the first satellite network system can be searched with the frequency band of the first satellite network system supported by the terminal device. If the first satellite network system is searched, the terminal device can be controlled to access the first satellite network system. Among them, the frequency band of the ground network system can also be referred to as the A network band, which can be a ground cellular network band. The frequency band of the first satellite network system can also be referred to as the B network band or the high-orbit satellite network band.

[0119] Optionally, based on the above priority information, the terminal device can search for networks on the ground cellular network frequency bands it supports. If the terminal device detects the signal of the ground network system and confirms that there is coverage of the ground network system (that is, ground cellular network coverage), it will give priority to initiating an access request in the ground network system to utilize the high speed and low latency services of the ground network.

[0120] Optionally, if the terminal device fails to find coverage of the ground network system after searching the frequency band of the ground network system, it can switch to searching the network on the high-orbit satellite network frequency band supported by the terminal device. The terminal device will perform network synchronization to ensure time and frequency synchronization with the high-orbit satellite network, and then receive system messages from the high-orbit satellite network, which contain necessary information for network configuration and operation.

[0121] In an embodiment of the present invention, by pre-configuring the network access priority and allowing the terminal device to search the network based on the above priority information, efficient coordination of the satellite and ground networks can be achieved while ensuring that users obtain appropriate service quality. In areas covered by ground networks, giving priority to the use of ground networks can avoid occupying satellite network resources and save satellite communication costs. In areas not covered by ground networks, by selecting high-orbit satellite networks or low-orbit satellite networks, users can be ensured to obtain communication services anywhere, especially when the high-orbit satellite network is used as an anchor network, the stability and availability of the network can be further improved.

[0122] In summary, through the intelligent network search and access selection strategy of the terminal device in the above method, the advantages of different network systems are effectively utilized to achieve seamless coverage and appropriate service selection for users. The above strategy not only improves the efficiency of network selection of terminal devices, but also optimizes the allocation and utilization of network resources, reduces interference between systems, and improves the performance of the overall network and the efficiency of spectrum utilization.

[0123] As an optional embodiment, the method also includes: in response to the terminal device accessing the first satellite network system and the first satellite network system being in an idle state, searching for the ground network system according to the frequency band of the ground network system supported by the terminal device and according to the target period; in response to searching the ground network system, controlling the terminal device to switch from the first satellite network system to the ground network system.

[0124] In this embodiment, when the terminal device accesses the first satellite network system and the first satellite network system is in an idle state, the ground network system can be searched for according to the target period in the frequency band of the ground network system supported by the terminal device. When the ground network system is searched, the terminal device can be controlled to switch from the first satellite network system to the ground network system.

[0125] Optionally, in the ID le state of the high-orbit satellite network system, the terminal device can periodically monitor the signal of the ground cellular network system, and preferentially access the ground cellular network system when the signal of the ground cellular network system is detected.

[0126] Optionally, in the Idle state, the terminal device is not in the process of any task, but still needs to maintain contact with the network so that it can quickly respond to paging requests (for example, incoming calls or data task requests). In this state, the terminal device will periodically monitor the paging channel provided by the high-orbit satellite network system and perform cell reselection measurements to ensure that it can connect to the appropriate network coverage when communication is required.

[0127] Optionally, although the terminal device currently resides in a high-orbit satellite network system, it will periodically monitor the signal of the ground cellular network system in the Id le state. The purpose of monitoring is to check whether the ground cellular network can provide services at the current location of the terminal device, because the ground cellular network can usually provide higher data rates and lower latency than the satellite network. The monitoring period and method are determined by the network side and can be notified to the terminal device through a message.

[0128] Optionally, when the terminal device detects that the signal of the terrestrial cellular network system is strong enough, it will give priority to accessing the terrestrial cellular network system. This decision is based on the preset network access priority (for example, A>B>C) and the terminal device's evaluation of signal strength and network performance. The reason for giving priority to accessing network A is that terrestrial cellular networks generally have better communication quality and higher capacity, especially in densely populated areas and well-developed infrastructure.

[0129] Optionally, in the Id le state, the terminal device periodically switches to the ground cellular network system frequency band to monitor the signal and measure the signal strength and quality according to the parameters configured on the network side. The terminal device evaluates the quality of the signal of the ground cellular network system, including but not limited to parameters such as signal strength, signal-to-noise ratio, and network load. If the signal quality of the ground cellular network system meets or exceeds the threshold set by the network side, the terminal device will determine that the ground cellular network system is a better access option. The terminal device can initiate an access request to the ground cellular network system, which is similar to the initial network access performed by the terminal device when it is turned on or moved to a new service area.

[0130] Optionally, once the ground cellular network system responds and establishes a connection, the terminal device will switch from the high-orbit satellite network system to the ground cellular network system for subsequent mission communications. This switch is performed by the terminal device and assisted by instructions from the network side, ensuring that the switch process is transparent to the user and does not affect the ongoing mission.

[0131] In an embodiment of the present invention, when the ground cellular network signal is available, higher speed data transmission and lower communication delay are provided to improve user satisfaction. The unnecessary occupation of satellite network resources is reduced, especially in areas with good ground network coverage, so that satellite frequency resources can more effectively serve other areas that need them more. By intelligently guiding the terminal device to a suitable available network, the interference between networks can be reduced, and the spectrum utilization efficiency and overall performance of the entire heterogeneous network can be improved. Through the above method, it can be ensured that the terminal device can select a network that meets the conditions for communication in a multi-layer heterogeneous network environment, whether in the ground cellular network coverage area or the satellite network coverage area, thereby achieving the purpose of improving spectrum utilization efficiency and network performance.

[0132] In an embodiment of the present invention, if the terminal device has a demand to be connected to a network system, the priority information of the fusion network system can be obtained, and the order in which the terminal device is connected to each network system in the fusion network system can be determined by the priority information. The network system to which the terminal device needs to be connected can be determined based on the above-mentioned priority information and the attribute information of the terminal device itself. If the network system accessed is a ground network system, the ground network configuration information in the ground network system can be used to interact with the terminal device, that is, the terminal device accesses the ground network system, and if the terminal device issues an interaction request, the ground network configuration information can be used to process the above-mentioned interaction request. If the network system accessed is the first satellite network system, it can be detected whether the terminal device initiates an interaction request. If it is detected that the terminal device initiates an interaction request, the request type of the interaction request can be determined, that is, whether the interaction request is a first target interaction request or a second target interaction request. If it is a first target interaction request, the interaction request can continue to be processed in the first satellite network system using the first configuration information. If it is a second target interaction request, it can be switched to the second satellite network system. At this time, the second satellite network system can receive the first configuration information sent by the first satellite network system, and then use its own second configuration information and the received first configuration information to process the interaction request.

[0133] In this embodiment, the ground network configuration information, the first configuration information, and the second configuration information can be comprehensively planned, so that when processing requests requiring a large bandwidth, other configuration information can be reused to increase the availability of configuration resources, thereby achieving the purpose of improving resource utilization efficiency, reducing interference between different network systems in the converged network system, and improving the reliability and overall performance of the network system. This achieves the technical effect of improving the information processing efficiency of the terminal device and solves the technical problem of low information processing efficiency of the terminal device.

[0134] Example 2

[0135] Another optional specific implementation is described in detail below.

[0136] At present, due to the different characteristics of communication network networking, satellite networks and ground networks are traditionally separate independent networks. The integration of satellite and ground networks will achieve complementary and comprehensive improvement in coverage and capacity of mobile communication networks. The coverage of ground communication systems is limited by the geographical environment and investment cost of base station equipment, making it difficult to achieve ubiquitous coverage; however, ground cellular communication networks have a large amount of medium and low frequency spectrum, and in areas without network coverage, this part of spectrum resources is not fully utilized; satellite networks can provide users with ubiquitous mobile communication services by using their coverage advantages, effectively supplementing the coverage shortcomings of ground networks; however, according to the radio division rules, the spectrum resources planned for satellite mobile communications and suitable for medium and low frequency mobile phone direct satellite applications are very limited. Traditional satellite mobile communication tasks can usually only provide narrowband mobile phone direct satellite tasks (such as voice, short messages, low-speed data tasks, etc.), and the medium and low frequency spectrum resources are tight, making it difficult to add dedicated frequency divisions to increase capacity. Low-orbit satellite operators have in-depth cooperation with telecom operators and terminal equipment manufacturers, and have adopted two technical routes based on satellite mobile communication frequencies and cellular mobile communication frequencies to promote the development of mobile phone direct satellite missions.

[0137] Optionally, when reusing ground cellular frequencies, the satellite network needs to effectively avoid interference with the ground network and effectively supplement the ground network coverage. High-orbit and low-orbit coordination will become the development trend of satellite communication system networking, and spectrum resources can be further shared to improve efficiency. In traditional satellite communications, high-orbit networks and low-orbit networks are used to support different wide-band and narrow-band mission applications, respectively, and are also implemented separately in terms of frequency usage and interference coordination. However, high-orbit and low-orbit coordination will become the development trend of satellite communication system networking, and spectrum resources can be further shared to improve efficiency.

[0138] Alternatively, high-orbit satellite systems can achieve ubiquitous satellite network coverage through fixed multi-beams, but the satellite orbit is high, the single beam covers a large area, and the link budget is low; low-orbit satellite systems can provide high-speed tasks relative to high-orbit systems, but the constellation scale is large, the construction cycle is long, and they are more suitable for providing high-speed data tasks in hot spots. Therefore, high-orbit and low-orbit coordination has gradually become the development trend of satellite communication systems. High-orbit satellite systems usually use fixed multi-beams to achieve wide-area continuous coverage. The diameter of a single beam is hundreds of kilometers. In order to avoid interference between beams, multi-color frequency multiplexing is usually used. Through the coordination mechanism of high- and low-orbit networks, in a given area, low-orbit satellites can reuse the spectrum resources of high-orbit satellites to improve the spectrum utilization efficiency of high- and low-orbit fusion systems.

[0139] Under the general trend of satellite-ground network integration and high-orbit and low-orbit integration, multi-system collaboration between networks has created conditions for spectrum sharing. However, how to coordinate multi-layer heterogeneous networks to share frequencies and improve spectrum utilization efficiency has become a challenge. Therefore, there is still a technical problem of low information processing efficiency of terminal devices.

[0140] The present invention proposes a terminal network selection method based on multi-layer network frequency sharing. The method achieves effective collaboration between networks, improves the efficiency of spectrum resource utilization, and ultimately improves the overall performance of the network by setting network access priorities and interference avoidance strategies based on signal perception. The fusion network spectrum resource pool and network access priority are pre-configured, such as ground cellular network> high-orbit satellite network> low-orbit satellite network, to ensure the priority order between different network levels. When the terminal is turned on, it searches for the network according to the preset access priority. When there is ground cellular network coverage, the ground cellular network is given priority; when the ground cellular network coverage is insufficient, the terminal will switch to the high-orbit satellite network and report its terminal capability information, including supported frequency bands and locations.

[0141] Optionally, for broadband mission requests, the high-orbit satellite network can determine the reusable frequency resource pool based on the terminal capabilities, network planning and mission load information, and then select the appropriate frequency point and beam in the low-orbit satellite network to complete resource configuration and guide the terminal to perform inter-frequency switching to the low-orbit satellite network. After the mission is completed, the terminal will automatically initiate inter-frequency switching and switch from the low-orbit satellite network back to the high-orbit satellite network. In the Id le state of the high-orbit satellite network, the terminal will also periodically monitor the ground cellular network so that it can be accessed first when the ground cellular network coverage is restored.

[0142] In this embodiment, the above method can realize effective frequency sharing between multiple layers of networks and improve the overall utilization efficiency of spectrum resources. Optimize user distribution and network capacity so that the network can provide appropriate services in different scenarios (such as remote areas or hot spots). Reduce interference between multiple layers of networks and improve network reliability and communication quality. In summary, frequency resource allocation and interference management in fusion and high- and low-orbit satellite network collaboration can be avoided. Thereby achieving the technical effect of improving the information processing efficiency of terminal devices and solving the technical problem of low information processing efficiency of terminal devices.

[0143] The method is further described below.

[0144] In this embodiment, Figure 2 is a flow chart of a method for selecting a network for a terminal device based on multi-layer network frequency sharing according to an embodiment of the present invention. Figure 2 As shown, the method may include the following steps:

[0145] Step S201, the terminal searches for networks according to a preset priority (network A>network B>network C).

[0146] In this embodiment, Table 1 is a result of stratification of converged network functions in an embodiment of the present invention. As shown in Table 1, priority stratification can be performed on the integrated space-ground multi-layer heterogeneous network to clarify the stratified functions of typical scenarios in terms of coverage and capacity. Taking the three-layer heterogeneous network of ground cellular network, high-orbit satellite network, and low-orbit satellite network as an example, the stratification of converged network functions is determined. Based on the stratification function, the spectrum resource pool is determined. A and B use dedicated spectrum resources, namely ground cellular spectrum resources and satellite mobile mission spectrum resources. Dedicated spectrum resources can provide guarantees for basic mobile communication service capabilities. Hot spot high-capacity task requests in remote areas can be met by reusing A and B network resources through the C network. At the same time, based on the stratification function, the priority order of A>B>C is used in terminal network search and task initiation.

[0148]

[0149] Optionally, the terminal is powered on and searches the network according to the preset access priority received.

[0150] Step S202, determine whether there is network coverage of A.

[0151] In this embodiment, by searching the network on the A network frequency band supported by the terminal, it can be determined whether the A network covers the location of the current terminal device. If so, step S204 is executed, otherwise, step S203 can be executed.

[0152] Step S203, determine whether there is network coverage of B.

[0153] In this embodiment, if there is no A network coverage, a network search is performed on the B network frequency band supported by the terminal, network synchronization is performed, and system messages are received.

[0154] Step S204: access network A.

[0155] In this embodiment, if there is coverage of network A, an access request is preferentially initiated in network A, and information is exchanged in network A.

[0156] Step S205: reporting terminal capability information.

[0157] In this embodiment, the terminal initiates initial access to the B network and reports the terminal capabilities, such as a list of working frequency bands supported by the terminal for the A network, terminal location information, and the like.

[0158] Step S206: Determine a resource pool that can be shared by the C network.

[0159] In this embodiment, based on the terminal capability reporting information (including the list of working frequency bands supported by the terminal for the A network, terminal location information, etc.), the B network carrier frequency / beam planning (including the configured frequency of the beam where the current terminal is located, the adjacent beam frequency planning), the B network task load, etc., and with minimizing interference as the criterion, the B network determines the frequency resource pool M (a subset of available resources for the A network and the B network) that the terminal can reuse to access the C network at its current location.

[0160] Step S207: Control the terminal to reside in the B network and enter the Idle state.

[0161] In this embodiment, the terminal resides in the B network and enters the Id le state.

[0162] Step S208: periodically search for network A and preferentially access network A.

[0163] In this embodiment, when accessing the B network and being in the Id le state, it can periodically search whether there is coverage of the A network. If so, the A network is accessed first.

[0164] Step S209: detecting a task initiated by the terminal or receiving a task request.

[0165] In this embodiment, the terminal resides in the B network and initiates a task or receives a task paging request. The network side of the B network makes a decision based on the request type (including data volume, latency, etc.) for establishing a connection between the task and the terminal.

[0166] Step S210, determining whether the task type is narrowband.

[0167] In this embodiment, it is determined whether the task initiated by the terminal or the task request received is a narrowband request or a broadband request. If it is a narrowband request, step S211 may be executed, otherwise, step S212 may be executed.

[0168] Step S211, entering the RRC connection state in the B network.

[0169] In this embodiment, when a narrowband task is requested (voice, short message), an RRC connection is established in the terminal in the B network.

[0170] Step S212: Optimize the frequency band and beam configuration through the C network according to the necessary information from the B network.

[0171] In this embodiment, the B network sends necessary system configuration information to the C network in one or more ways, including the reusable spectrum resource pool M, terminal location information, etc. The C network combines the frequency band support capability of the system, optimizes the frequency point and beam through an algorithm, completes the configuration decision of the carrier and beam resources, and informs the B network. The network side of the B network sends necessary inter-frequency switching information and instructions to the terminal; the terminal initiates inter-frequency switching measurement and selects the target cell of the C network, and the terminal switches to the C network to establish an RRC connection.

[0172] Step S213: The terminal initiates an inter-frequency handover measurement to switch from the B network to the C network.

[0173] In this embodiment, the network side of the B network sends necessary inter-frequency switching information and instructions to the terminal.

[0174] Step S214: Enter the RRC connection state in the C network.

[0175] In this embodiment, the terminal initiates inter-frequency handover measurement and selects a target cell of the C network, and the terminal switches to the C network to establish an RRC connection.

[0176] Step S215: Task completed, entering the B network ID le state.

[0177] In this embodiment, after the task is completed, the terminal enters the Id le state and automatically initiates an inter-frequency handover from the C network back to the B network.

[0178] Step S216: periodically search for network A and preferentially access network A.

[0179] In this embodiment, the terminal periodically monitors the A network in the B network ID le state and preferentially accesses the A network.

[0180] In the embodiment of the present invention, multi-layer network priorities are pre-configured; the network side confirms the frequency sharing resource pool through measurement perception and reporting based on terminal capabilities; the terminal network search and task flow are completed according to the multi-layer network priorities and the frequency sharing resource pool, avoiding the problem of multi-layer network interference, improving the efficiency of spectrum resource use, and improving the overall performance of the network. Thus, the technical effect of improving the information processing efficiency of the terminal device is achieved, and the technical problem of low information processing efficiency of the terminal device is solved.
