Example 1

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 flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, Although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

Fig. 1 is a flow chart of a network channel switching method according to an embodiment of the present invention. As shown in Fig. 1, the method includes the following steps:

Step S102, receiving the network switching request information of the target user, and receiving the network load information of the target satellite, wherein the network switching request information includes the current network level information of the target user;

Step S104: Determine a network handover candidate set based on the network handover request information and the network load information, wherein the network handover candidate set includes at least one target base station;

Step S106, determining the network channel of the target base station from the network handover candidate set to perform network channel handover.

In the embodiment of the present invention, the execution subject of the above-mentioned steps S102 to S106 is the network channel switching system, and the above-mentioned system is used to receive the network switching request information of the target user and at the same time receive the network load information of the target satellite, based on the above-mentioned network switching request information and The network load information determines a network handover candidate set, and determines the target base station from the network handover candidate set, and uses the network channel of the target base station to perform network channel handover.

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

In the embodiment of the present invention, in the emergency communication scenario, an asymmetric QoS mapping mechanism is used for QoS mapping of services between different networks; after QoS mapping, the detectable base station/beam set constitutes a candidate set; Select the base station/beam with the highest level after QoS mapping in the candidate set to form the target set; if there is only one optional base station/beam in the target set, then this base station/beam is the target base station/beam; if there are multiple base stations/beams available in the target set If selected, the one with the highest received signal power is selected as the target base station/beam.

It should be noted that both the terrestrial 5G network and the satellite network have a complete set of QoS classification mechanism. According to the current mechanism, the classification of emergency communication services in the terrestrial 5G network and the satellite network is as follows: The services provided by the terrestrial 5G network based on 5G Classification, according to the sensitivity of different services to indicators such as delay, mobile Internet services can be divided into the following five levels, namely: conversation (Conversation), streaming media (Streaming), interactive (Interactive), transmission (Transmissive) and message class (Message). Conversational services are delay-sensitive real-time services, mainly including video sessions, real-time video conferencing and other services, with the highest QoS guarantee level; streaming media services refer to the real-time performance of audio and video playback through streaming media The service, which outputs media data by downloading, caching, and playing, is less sensitive to the delay requirement than the conversational service; the interactive service is a service that interrupts the online data interaction between the user and the remote device, and its characteristics are The request-response mode usually includes services such as location and browsing. The delay of interactive services depends on people's tolerance for waiting time, which is usually longer than that of streaming media services.

As an optional embodiment, as shown in Figure 2, a schematic diagram of the QoS mapping between the terrestrial 5G network and the satellite 5G communication emergency service. When the network transmits emergency communications, according to the current network capacity and service characteristics, the emergency communications service will be divided into two types: session type (QoS level 1) and streaming media type (QoS level 2). Services with high QoS requirements such as interaction and video conferencing will be classified as conversational; when media data such as video, pictures, or voice are transmitted, streaming media services with relatively loose QoS requirements will be used.

As an optional embodiment, as shown in Figure 3, the QoS mapping diagram of the terrestrial 5G network and the satellite DVB-S/RCS communication emergency service, in the GEO satellite communication system, when the 5G satellite communication system is used, the service is divided It is the same five levels as terrestrial 5G, but due to the limitation of longer transmission path and smaller network capacity, its performance such as delay and transmission quality is not as high as that of terrestrial 5G. Therefore, in the satellite 5G communication system, emergency communication services that require high real-time and interactivity will be divided into three types: conversational, streaming media, and interactive. Among them, video conferencing and other services that require high QoS According to the current network capacity, it may be classified as conversational or streaming media services, and transmission services such as video, image and voice may be classified as streaming media or interactive services.

As an optional embodiment, when the DVB-S/RCS satellite communication system is used, there are five types of services supported in the network, and the QoS priorities of the five types of services are arranged in order from high to low: CRA, RBDC , VBDC, AVBDC and FCA, among which the emergency communication service will be divided into three types: CRA, RBCD and VBDC. If the ground 5G network is switched to the satellite communication system, the capacity of the satellite network is not enough to meet the mapping of the same QoS level, it is acceptable to appropriately reduce the communication quality/transmission delay and access to a lower QoS level, among which the emergency transmission communication service Classification is similar to that in the 5G satellite communication system. Services such as video conferencing may be classified as CRA or RBCD according to the current network capacity, and the transmission of streaming media data such as video, image or voice may be classified as RBCD or VBDC.

It should be noted that CRA (Continuous Rate Allocation) indicates that all bandwidth requirements for this type of request must be met in each superframe; RBDC (Rate Based Dynamic Capacity) indicates that this type of request proposes bandwidth requirements at a specified code rate; VBDC (Volume Based Dynamic Capacity) indicates that this type of request proposes bandwidth requirements in the form of specified capacity; AVBDC (Absolute Volume Based Dynamic Capacity) indicates that this type of request proposes bandwidth requirements in the form of specified capacity, which differs from VBDC in that the request made by AVBDC The previous request will be overwritten, and the VBDC request is cumulative; FCA (Free Capacity Assignment) indicates that this type of request has no bit rate and capacity requirements, and NCC indicates that the idle bandwidth is directly allocated to each RCST in a certain way, instead of RCST is required to make such a request again.

In the embodiment of the present invention, the asymmetric QoS mapping mechanism in the emergency communication scene is adopted to solve the problem of high network switching blocking rate of the traditional one-to-one symmetric mapping mechanism. The vertical handover method of the satellite-ground fusion network based on the QoS mapping mechanism also realizes seamless handover between satellite-ground networks in emergency scenarios.

In an optional embodiment, the determining the network handover candidate set based on the network handover request information and the network load information includes: judging the QoS level of the current network of the target user based on the network handover request information, wherein , the above-mentioned QoS level includes: QoS level 1 and QoS level 2; the network switching threshold is determined based on the above-mentioned QoS level, wherein the above-mentioned network switching threshold corresponding to the above-mentioned QoS level 1 is the first network switching threshold, and the above-mentioned network switching threshold corresponding to the above-mentioned QoS level 2 The handover threshold is a second network handover threshold; and the network handover candidate set is determined based on the network handover threshold and the load information.

In the embodiment of the present invention, after receiving the user's network switching request, the QoS level of the user in the current network is judged. When the user switches from the terrestrial 5G network to the satellite network, the emergency communication services in the terrestrial and satellite networks will be defined as three grades of 1-3 according to the QoS requirements, and the ground service will be divided into 1 and 2. Level, the business in the satellite network is divided into three levels of 1-3.

In an optional embodiment, when the QoS class of the current network of the target user is the QoS class 1, the determining the network handover candidate set based on the network handover threshold and the load information includes: determining The load value corresponding to the above load information; if the above load value is less than the above first network switching threshold, then determine the target QoS level is the above QoS level 1; if the above load value is greater than the above first network switching threshold and less than the above second network switching threshold , then it is determined that the target QoS level is the above-mentioned QoS level 2; if the load value is greater than the second network switching threshold, the switching fails and the switching request is blocked; the network switching candidate set is determined based on the target QoS level.

In the embodiment of the present invention, as shown in the flow chart of the QoS mapping method of the satellite-to-earth network as shown in FIG. 4 , if the user's level in the current network is 1, the relationship between the current satellite network load and the switching thresholds of each level is judged. If the current satellite network load is less than the switching threshold of the current user QoS level, the user level after switching is the same as the level in the original network before switching, which is 1; if the current satellite network load is greater than the switching threshold of the current user QoS level but lower than the higher level QoS switching threshold, the QoS level of the user after switching is one level higher than the QoS level in the original network, which is 2; if the current satellite network load is greater than the higher level of QoS switching threshold, the switching fails and the switching request is blocked.

In an optional embodiment, when the QoS class of the current network of the target user is the QoS class 2, the determining the network handover candidate set based on the network handover threshold and the load information includes: determining The load value corresponding to the above load information; if the above load value is less than the above second network switching threshold, then determine the target QoS level is the above QoS level 2; if the above load value is greater than the above second network switching threshold and less than the third network switching threshold, Then determine that the target QoS class is QoS class 3; if the load value is greater than the third network handover threshold, the handover fails and the handover request is blocked; determine the network handover candidate set based on the target QoS class.

In the embodiment of the present invention, the flow chart of the QoS mapping method of the satellite-to-earth network is still shown in Figure 4. If the user is at level 2 in the current network, it is similar to the situation at level 1. If the current satellite network load is less than the current user QoS If the switching threshold of the level is used, the user’s level after switching is the same as the level in the original network before switching, which is 2; The QoS level is one level higher than the QoS level in the original network, which is 3; if the current satellite network load is greater than the higher level QoS switching threshold, the switching fails and the switching request is blocked.

It should be noted that when the user switches from the satellite network to the terrestrial network, considering that the terrestrial network has a relatively larger system capacity and better link quality than the satellite network, this solution adopts a simple One-to-one mapping method (as shown in the dotted line in the mapping schematic diagram of Figure 1), that is, each service request can obtain the desired resource, namely:

Optionally, when a user switches from a satellite network to a terrestrial network, since the terrestrial 5G network has larger capacity and better communication quality than the satellite network, a simple one-to-one mapping can be used.

In the embodiment of the present invention, as shown in FIG. 5 , a schematic diagram of the confirmation process of the target base station is shown. The network channel switching of the above-mentioned target base station is determined from the above-mentioned network handover candidate set, including: if there is only one initial base station in the above-mentioned network handover candidate set , then determine the above-mentioned initial base station as the above-mentioned target base station; if there are multiple above-mentioned initial base stations in the above-mentioned network handover candidate set, then determine the above-mentioned initial base station with the largest received signal power as the above-mentioned target base station; use the above-mentioned network channel of the above-mentioned target base station to perform network channel switch.

Through the above steps, by receiving the network switching request information of the target user and receiving the network load information of the target satellite, wherein the above-mentioned network switching request information includes the current network level information of the above-mentioned target user; based on the above-mentioned network switching request information and the above-mentioned network load Information to determine a network handover candidate set, wherein the above-mentioned network handover candidate set includes at least one target base station; determine the network channel of the above-mentioned target base station from the above-mentioned network handover candidate set to perform network channel handover, and achieve the network level according to different service categories. The purpose of asymmetric QoS mapping between ground and ground networks, thereby realizing the technical effect of vertical switching between satellite and ground fusion networks in emergency scenarios, and then solving the technical problems of poor adaptability and high blocking rate in network channel switching methods in the prior art .
