Description

Technical Field

[0001] This invention relates to the field of communication technology, and more specifically, to a network channel switching method and apparatus, a storage medium, and a processor. Background Technology

[0002] Fifth-generation mobile communication technology (5G) is widely used due to its advantages such as high speed, low latency, high stability, and large capacity. However, after natural or man-made disasters, damage to transportation, communication, and power facilities in disaster areas, or remote locations, can cause terrestrial 5G network communication lines to be interrupted or unable to provide coverage, hindering disaster relief operations. By combining the wide-coverage and interference-resistant GEO satellite network with the terrestrial 5G communication network, an emergency communication space-ground converged network with wide coverage, strong environmental adaptability, and rapid communication recovery can be established.

[0003] To ensure high-quality emergency communication, seamless switching between satellite and terrestrial communication systems is required based on the current network quality. Since different networks define QoS levels differently, QoS level mapping between different networks is essential during switching.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] Example 1

[0026] According to an embodiment of the present invention, an embodiment of a network channel switching method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0027] Figure 1 This is a flowchart of a network channel switching method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0028] Step S102: Receive network switching request information from the target user and network load information from the target satellite, wherein the network switching request information includes the current network level information of the target user;

[0029] Step S104: Based on the network handover request information and the network load information, determine the network handover candidate set, wherein the network handover candidate set includes at least one target base station;

[0030] Step S106: Determine the network channel of the target base station from the network handover candidate set and perform network channel handover.

[0031] In this embodiment of the invention, the execution subject of the above steps S102 to S106 is a network channel switching system. The system receives network switching request information from the target user and network load information from the target satellite. Based on the network switching request information and the network load information, a network switching candidate set is determined, and the target base station is determined from the network switching candidate set. The network channel of the target base station is used to perform network channel switching.

[0032] It should be noted that the aforementioned network handover request information includes the current network level information of the target user; the aforementioned network handover candidate set includes at least one target base station.

[0033] In this embodiment of the invention, in an emergency communication scenario, an asymmetric QoS mapping mechanism is used to map services across different networks. After QoS mapping, the detectable base stations / beams are used to form a candidate set. The base station / beam with the highest QoS level after QoS mapping in the candidate set is selected to form the target set. If there is only one selectable base station / beam in the target set, then that base station / beam is the target base station / beam. If there are multiple base stations / beams to choose from in the target set, then the one with the highest received signal power is selected as the target base station / beam.

[0034] It should be noted that both terrestrial 5G networks and satellite networks have a comprehensive QoS level classification mechanism. Based on the current mechanism, emergency communication services are classified in terrestrial 5G networks and satellite networks as follows: Terrestrial 5G networks classify services based on their 5G service offerings. According to the different sensitivities of various services to latency and other indicators, mobile internet services can be divided into the following five levels: Conversation, Streaming, Interactive, Transmissive, and Message. Conversation services are latency-sensitive real-time services, mainly including video conferencing and real-time video conferencing, and have the highest QoS guarantee level. Streaming services are real-time services that play audio and video in streaming media, outputting media data through simultaneous downloading, caching, and playback; their latency requirements are not as sensitive as those of conversation services. Interactive services interrupt online data interaction between users and remote devices, characterized by a request-response model, typically including location-based and browsing services. The latency of interactive services depends on people's tolerance for waiting time and is usually longer than that of streaming media services.

[0035] As an optional embodiment, such as Figure 2 The diagram showing the QoS mapping between terrestrial 5G networks and satellite 5G communication emergency services illustrates that, due to the high requirements for real-time performance, interactivity, and communication quality in emergency communication transmission, when using 5G networks for emergency communication transmission, emergency communication services are divided into two types based on current network capacity and service characteristics: session-based (QoS level 1) and streaming media-based (QoS level 2). When transmitting real-time information about the disaster area and conducting command interactions, video conferencing, and other services with high QoS requirements, session-based services are used; when transmitting media data such as video, images, or voice, streaming media-based services with relatively relaxed QoS requirements are used.

[0036] As an optional embodiment, such as Figure 3 The diagram illustrates the QoS mapping between terrestrial 5G networks and satellite DVB-S / RCS communication emergency services. In GEO satellite communication systems, when using 5G satellite communication, services are divided into the same five levels as in terrestrial 5G. However, due to limitations in longer transmission paths and smaller network capacity, its performance in terms of latency and transmission quality is not as high as that of terrestrial 5G. Therefore, in satellite 5G communication systems, emergency communication services with high real-time and interactivity requirements are divided into three types: session-based, streaming media-based, and interactive. Among these, services with high QoS requirements, such as video conferencing, may be classified as session-based or streaming media-based services depending on the current network capacity, while video, image, and voice transmission services may be classified as streaming media-based or interactive.

[0037] As an optional implementation, when using the DVB-S / RCS satellite communication system, the network supports five types of services, arranged in descending order of QoS priority: CRA, RBDC, VBDC, AVBDC, and FCA. Emergency communication services are further divided into CRA, RBDC, and VBDC. If the satellite network capacity is insufficient to meet the mapping requirements of the same QoS level when switching from the terrestrial 5G network to the satellite communication system, a lower QoS level can be accepted by appropriately reducing communication quality / transmission latency. The QoS level classification for emergency transmission communication services is similar to that in the 5G satellite communication system. Services such as video conferencing may be classified into CRA or RBDC depending on the current network capacity, and the transmission of streaming media data such as video, images, or voice may be classified into RBCD or VBDC.

[0038] It should be noted that CRA (Continuous Rate Allocation) means that all bandwidth requirements of this type of request must be met in each superframe; RBDC (Rate Based Dynamic Capacity) means that this type of request submits bandwidth requirements at a specified bitrate; VBDC (Volume Based Dynamic Capacity) means that this type of request submits bandwidth requirements at a specified capacity; AVBDC (Absolute Volume Based Dynamic Capacity) means that this type of request submits bandwidth requirements at a specified capacity, but unlike VBDC, AVBDC requests will overwrite previous requests, while VBDC requests are cumulative; FCA (Free Capacity Assignment) means that this type of request has no bitrate or capacity requirements; NCC means that idle bandwidth is directly allocated to each RCST in some way, without the RCST needing to submit this type of request again.

[0039] In this embodiment of the invention, an asymmetric QoS mapping mechanism for emergency communication scenarios is adopted, which solves the problem of high network handover blocking rate in traditional one-to-one symmetric mapping mechanisms. The vertical handover method for space-ground integrated networks based on the QoS mapping mechanism also achieves seamless handover between space-ground networks in emergency scenarios.

[0040] In an optional embodiment, determining the network handover candidate set based on the network handover request information and the network load information includes: determining the QoS level of the target user's current network based on the network handover request information, wherein the QoS level includes QoS level 1 and QoS level 2; determining a network handover threshold based on the QoS level, wherein the network handover threshold corresponding to QoS level 1 is a first network handover threshold, and the network handover threshold corresponding to QoS level 2 is a second network handover threshold; and determining the network handover candidate set based on the network handover threshold and the load information.

[0041] In this embodiment of the invention, after receiving a user's network switching request, the QoS level of the user in the current network is determined. When a user switches from a terrestrial 5G network to a satellite network, emergency communication services in the terrestrial and satellite networks are defined as three levels (1-3) according to their QoS requirements. Terrestrial services are divided into two levels (1 and 2), while services in the satellite network are divided into three levels (1-3).

[0042] In an optional embodiment, when the QoS level of the target user's current network is QoS level 1, determining the network handover candidate set based on the network handover threshold and the load information includes: determining the load value corresponding to the load information; if the load value is less than the first network handover threshold, determining the target QoS level as QoS level 1; if the load value is greater than the first network handover threshold and less than the second network handover threshold, determining the target QoS level as QoS level 2; if the load value is greater than the second network handover threshold, the handover fails and the handover request is blocked; and determining the network handover candidate set based on the target QoS level.

[0043] In embodiments of the present invention, such as Figure 4 The flowchart of the satellite-to-ground network QoS mapping method shows that if the user's QoS level is 1 in the current network, the relationship between the current satellite network load and the switching thresholds for each QoS level is determined. If the current satellite network load is less than the switching threshold for the current user's QoS level, the user's QoS level after the switch is the same as the original network level before the switch, which is 1. If the current satellite network load is greater than the switching threshold for the current user's QoS level but less than the higher-level QoS switching threshold, the user's QoS level after the switch is one level higher than the original network QoS level, which is 2. If the current satellite network load is greater than the higher-level QoS switching threshold, the switch fails, and the switch request is blocked.

[0044] In an optional embodiment, when the QoS level of the target user's current network is QoS level 2, determining the network handover candidate set based on the network handover threshold and the load information includes: determining the load value corresponding to the load information; if the load value is less than the second network handover threshold, determining the target QoS level as QoS level 2; if the load value is greater than the second network handover threshold and less than the third network handover threshold, determining the target QoS level as QoS level 3; if the load value is greater than the third network handover threshold, the handover fails and the handover request is blocked; and determining the network handover candidate set based on the target QoS level.

[0045] In the embodiments of the present invention, it remains as follows Figure 4 The flowchart of the satellite-to-ground network QoS mapping method shows that if the user's QoS level in the current network is level 2, the process is similar to level 1. If the current satellite network load is less than the switching threshold for the current user's QoS level, the user's QoS level after the switch is the same as the original network level before the switch, which is 2. If the current satellite network load is greater than the switching threshold for the current user's QoS level but less than the higher-level QoS switching threshold, the user's QoS level after the switch is one level higher than the original network QoS level, which is 3. If the current satellite network load is greater than the higher-level QoS switching threshold, the switch fails and the switch request is blocked.

[0046] It should be noted that when users switch from satellite networks to terrestrial networks, considering that terrestrial networks have relatively larger system capacity and better link quality compared to satellite networks, this solution adopts a simple one-to-one mapping method (e.g., Figure 1 The dashed lines in the mapping diagram represent the portion where each business request can obtain the desired resource.

[0047]

[0048] Optionally, when users switch from satellite networks to terrestrial networks, a simple one-to-one mapping can be used because terrestrial 5G networks have greater capacity and better communication quality compared to satellite networks.

[0049] In embodiments of the present invention, such as Figure 5 The diagram illustrates the target base station confirmation process. The above-mentioned determination of the network channel of the target base station from the network handover candidate set and the network channel handover includes: if there is only one initial base station in the network handover candidate set, then the initial base station is determined to be the target base station; if there are multiple initial base stations in the network handover candidate set, then the initial base station with the highest received signal power is determined to be the target base station; and the network channel handover is performed using the network channel of the target base station.

[0050] Through the above steps, by receiving network switching request information from the target user and network load information from the target satellite, wherein the network switching request information includes the target user's current network level information; based on the network switching request information and the network load information, a network switching candidate set is determined, wherein the network switching candidate set includes at least one target base station; the network channel of the target base station is determined from the network switching candidate set for network channel switching, thereby achieving the purpose of asymmetric QoS mapping between satellite and ground networks according to the network level of different service categories, thus realizing the technical effect of vertical switching between satellite and ground converged networks in emergency scenarios, and solving the technical problems of poor adaptability and high blocking rate in existing network channel switching methods.
