Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication engineering, and particularly relates to a multi-communication shared transmission method and system based on a tunnel theory. BACKGROUND

[0002] With the rapid development of information technology, modern communication systems show high diversification and complex characteristics. Heterogeneous networks such as mobile communication, wireless local area network and Ethernet operate in different frequency bands and use different protocols to meet the diversified application requirements. However, with the evolution of mobile communication technology, its service form has changed from traditional voice communication to data service. Especially under the background of the gradual popularization of 5G network and the wide application of intelligent terminals, mobile data traffic shows exponential growth, and the access layer needs to carry a large number of concurrent connections. Currently, mobile network services cover web browsing, instant messaging, social networks, e-commerce, video streaming and online gaming, and are deeply integrated into people's daily life. As an important driving force for the evolution of the Internet, mobile Internet services not only reshape traditional communication patterns, but also give birth to new business models and achieve sustainable development. In addition, the evolution of user communication behavior and the popularity of intelligent terminals further exacerbate the dependence on network resources and promote the growth of new communication resource demand. At the same time, wearable devices, smart cities, intelligent medical care, Internet of Vehicles and machine communication put forward higher requirements for the network. These changes make the efficient coexistence of multiple communication systems in a complex network environment a core problem to be solved. In the modern communication system, the coexistence and transmission optimization of multiple communication systems have become a key research direction, mainly involving two typical scenarios: (1) coexistence of cellular networks and Wi-Fi networks in unlicensed frequency bands (local area network environment); (2) coexistence of cellular networks and Ethernet (across local area network environment). This problem not only involves efficient sharing and coordination of spectrum resources, but also covers transmission path optimization and management. With the continuous expansion of network size and the improvement of user demand for high-quality communication services, how to realize the harmonious coexistence and efficient transmission of heterogeneous communication systems in a complex network environment has become a hot and difficult point of current research.

[0003] Currently, there are some methods proposed to realize the coexistence of mobile communication systems and wireless communication systems in unlicensed frequency bands. For example, the CSAT mechanism introduced by Qualcomm in the LTE base station realizes the fair coexistence of Wi-Fi and LTE-U by adjusting the duty cycle; the LTE-LAA scheme designed by 3GPP based on the LBT mechanism uses channel energy detection for access control. However, these methods have many problems. The scheme based on the CSAT mechanism faces challenges in determining the optimal duty cycle, and the existing coexistence schemes still need to be improved in fairness and spectrum utilization efficiency; the LBT mechanism differs in different regions and has technical limitations, and the current mainstream CSAT and LBT mechanisms are controlled by the LTE system, which may severely affect the performance of the Wi-Fi system when optimizing the performance of the LTE system. Then, these coexistence mechanisms can only be applied to the coexistence between LTE / 5G and Wi-Fi, and do not involve the coexistence between wireless networks and wired networks.

[0004] Therefore, in the process of data transmission of the conventional multi-communication system, the transmission efficiency is low, the network resource utilization rate is not high, and the overall communication performance is poor. SUMMARY

[0049] For the purpose of the present application, technical solutions and advantages, the following will be further described in detail in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0050] It can be understood that the terms "first", "second" and the like used in the present application can be used herein to describe access points, cellular network datagrams, Wi-Fi data frames, but these access points, cellular network datagrams, Wi-Fi data frames are not limited by these terms. These terms are only used to distinguish the first access point, cellular network datagram, Wi-Fi data frame from another access point, cellular network datagram, Wi-Fi data frame. For example, without departing from the scope of the present application, the first access point can be called the second access point, and similarly, the second access point can be called the first access point. The first access point and the second access point are both access points, but they are not the same access point.

[0051] The multi-communication sharing transmission method based on the tunnel theory provided by the embodiments of the present application can be applied to the application environment as shown in Figure 1 、 Figure 2 As shown in Figure 1 、 Figure 2 The application environment includes a mobile communication and Wi-Fi coexistence system within a local area network, a mobile communication and Ethernet coexistence system across a local area network. As shown in Figure 1 In the mobile communication and Wi-Fi coexistence system within a local area network, the Wi-Fi system includes an access point (AP) and a plurality of stations (STAs), and the mobile communication system includes a base station (BS) and a plurality of user equipment (UEs); when transmitting in an unlicensed frequency band, the uplink of the mobile communication system uses a licensed frequency band, and the downlink shares the unlicensed frequency band with the Wi-Fi system. As shown in Figure 2 The mobile communication and Ethernet coexistence system across a local area network includes a plurality of APs and a plurality of STAs, as well as a BS and a plurality of UEs, and also includes a router required for Ethernet transmission.

[0052] In one embodiment, as shown in Figure 3 A multi-communication sharing transmission method based on the tunnel theory is provided, including the following steps:

[0053] Step 302, before the start of the data transmission period, the first base station in the local area network sends the channel state information, time resource block demand, and the first cellular network data packet to the first access point, and the first access point calculates the time resource block allocation strategy according to the channel state information and the time resource block demand.

[0054] In the process of sharing transmission of the mobile communication network LTE / 5G and the Wi-Fi network in the unlicensed frequency band in the local area network, the first base station and the first access point exchange information before the start of each transmission period, and share the channel state information and the time resource block demand. The SDN controller at the first access point end evaluates whether the mobile communication network has the condition of sharing the unlicensed frequency spectrum based on the received channel state information, and calculates the optimized time resource block allocation strategy.

[0055] In one embodiment, the multi-communication sharing transmission method based on the tunnel theory can further include the process of dividing the transmission period and judging whether the condition of sharing the frequency band is met, and the specific process includes: in the process of sharing transmission of the mobile communication network and the Wi-Fi network in the unlicensed frequency band in the local area network, time is divided into transmission periods; each transmission period is composed of time resource blocks; the first access point evaluates whether the mobile communication network has the condition of sharing the unlicensed frequency band based on the channel state information, and if it has, the first base station communicates with the first access point, and the first base station sends the first cellular network data packet corresponding to the user equipment to the first access point.

[0056] In the process of sharing transmission of the mobile communication network LTE / 5G and the Wi-Fi network in the unlicensed frequency band in the local area network, time can be divided into multiple transmission periods, and each period is composed of R time resource blocks, denoted as r={1, 2,..., R}.

[0057] Specifically, in one embodiment, the multi-communication sharing transmission method based on the tunnel theory can further include the process of judging whether the condition of sharing the frequency band is met, and the specific process includes: the first access point judges whether there is idle channel resource in the unlicensed frequency band of the Wi-Fi network according to the channel state information; if there is idle channel resource, it is judged whether the channel resource of the mobile communication network in the licensed frequency band can meet the time resource block demand corresponding to the user equipment; if the time resource block demand can be met, the mobile communication network has the condition of sharing the unlicensed frequency band.

[0058] That is, in this embodiment, the basic conditions for coexistence of the mobile communication network LTE / 5G and the Wi-Fi network include: first, there is underutilized channel resource in the unlicensed frequency band of the Wi-Fi network; second, the resources of the mobile communication network LTE / 5G in the licensed frequency spectrum are insufficient to meet the demand of the user equipment UE.

[0059] When the basic conditions for coexistence of the mobile communication network LTE / 5G and the Wi-Fi network are met, the first base station BS will communicate with the first access point AP and transmit the mobile signal data frame and related information required by the user equipment UE to the first access point AP.

[0060] In step 304 , the first access point encapsulates the first cellular network datagram using the reserved bit through a tunnel encapsulation technology to obtain a first Wi-Fi data frame; the first access point sends the first Wi-Fi data frame to the user equipment according to the time resource block allocation policy.

[0061] In networks where LTE / 5G and Wi-Fi coexist, since both operate independently in unlicensed frequency bands and compete for channel resources, conflicts can increase, impacting the quality of service for Wi-Fi users. To improve spectrum efficiency and reduce coexistence interference, a shared transmission mechanism based on tunnel encapsulation technology has been introduced to achieve harmonious coexistence between LTE / 5G and Wi-Fi networks. Specifically, this shared transmission mechanism encapsulates cellular network datagrams through Wi-Fi APs, allowing them to be transmitted on unlicensed channels as Wi-Fi data frames.

[0062] In one embodiment, a multi-communication shared transmission method based on tunneling theory may further include a data encapsulation process. The specific process includes: a first access point uses a tunneling encapsulation technique to use a cellular network datagram as a payload and encapsulates the cellular network datagram in an initial data frame using reserved bits; obtains a header and a trailer of a MAC frame, and adds the header and the trailer to the initial data frame to construct a first Wi-Fi data frame; after the first access point sends the first Wi-Fi data frame to a user device according to a time resource block allocation policy, the process further includes: the user device parses the header of the first Wi-Fi data frame to identify and recover the original data.

[0063] Among them, Figure 4 As shown, the first access point AP uses the tunnel encapsulation technology to use the mobile communication data frame, namely the first cellular network datagram, as the payload of the Wi-Fi data frame, and combines it with the IEEE 802.11 MAC frame header and frame tail to construct a complete Wi-Fi data frame, and finally transmits it to the user equipment UE through the Wi-Fi AP.

[0064] Specifically, the first access point AP encapsulates the data into a Wi-Fi data frame using a reserved bit according to the tunnel transmission mechanism, and adds a frame header and a frame trailer to form a new Wi-Fi data frame.

[0065] In one embodiment, the tunneling-based multi-communication sharing transmission method further includes a process of defining a reserved bit to distinguish data frames, which includes: using a first field combination in the reserved bit when the first access point sends regular data to other stations; using a second field combination in the reserved bit when the first access point sends mobile communication data to the user equipment; and encapsulating the first field combination or the second field combination in an initial data frame together with cellular network data packets.

[0066] In the tunneling transmission mechanism, the Type and Subtype combinations in the IEEE 802.11 MAC frame structure are used to distinguish mobile communication data frames from Wi-Fi data frames by redefining the reserved bit. Specifically, when the Wi-Fi AP sends a regular data frame, the Type and Subtype combination is “100000”, and when the AP sends a mobile communication data frame, the combination “100001” is used. The mobile communication data is encapsulated into the Wi-Fi data frame by the tunneling encapsulation technology, so that the UE can correctly parse and recover the original data. In this embodiment, the extension of the frame header information enables the UE and the STA to accurately identify the source and type of the received data.

[0067] In one embodiment, the tunneling-based multi-communication sharing transmission method further includes a resource allocation process, which includes: calculating a resource allocation scheme by the first access point according to a time resource block allocation strategy; determining a target time resource block based on the resource allocation scheme; and sending the first Wi-Fi data frame to the user equipment in the target time resource block.

[0068] The first access point AP sends data to the user equipment UE or the station STA in the corresponding time resource block according to the calculated allocation scheme. For example, in the time resource block allocated to the user equipment UE, the first access point AP sends the Wi-Fi frame encapsulating the mobile communication data to the corresponding UE, and the UE identifies the data type by parsing the frame header and receives and processes the data.

[0069] In one embodiment, as shown in Figure 1 The tunneling transmission mechanism encapsulates the first cellular network data packet by the Wi-Fi AP, so that the first cellular network data packet can be transmitted in the form of a Wi-Fi data frame on an unlicensed channel. In this embodiment, the UE directly receives the first cellular network data packet from the Wi-Fi AP, rather than being directly transmitted by the BS, thereby optimizing the scheduling strategy of the channel resources and effectively reducing the potential channel competition and interference between the LTE / 5G network and the Wi-Fi network.

[0070] As shown in Figure 1As shown, in a coexistence network of mobile communication network LTE / 5G and Wi-Fi network, since LTE / 5G and Wi-Fi networks operate independently in unlicensed frequency bands and both need to compete for channel resources, conflicts may increase, thereby affecting the service quality of Wi-Fi users. In order to improve spectrum utilization efficiency and reduce coexistence interference, a shared transmission mechanism based on tunnel encapsulation technology is introduced to achieve harmonious coexistence of LTE / 5G and Wi-Fi networks. Specifically, the shared transmission mechanism based on tunnel encapsulation technology encapsulates the first cellular network datagram through the Wi-Fi AP, so that the first cellular network datagram can be transmitted on the unlicensed channel in the form of a Wi-Fi data frame. The UE receives the first cellular network datagram directly from the Wi-Fi AP instead of directly transmitting it through the BS, thereby optimizing the scheduling strategy of channel resources and effectively reducing potential channel contention and interference between the LTE / 5G network and the Wi-Fi network.

[0071] Step 306: In the inter-local area network, the second base station sends a second cellular network datagram to the second access point. The second access point encapsulates the second cellular network datagram into an Ethernet frame and sends the frame to the third access point.

[0072] In one embodiment, a multi-communication shared transmission method based on tunnel theory may also include a process of encapsulating an Ethernet frame, the specific process including: a second access point receives a second cellular network datagram sent by a second base station, and embeds the second cellular network datagram as a payload into the Ethernet frame.

[0073] like Figure 5 As shown, during the LTE / 5G and Ethernet coexistence network deployment phase, a shared transmission mechanism based on tunneling theory embeds the second cellular network datagram into a Wi-Fi data frame. When transmitted over a wired network, it is then embedded into an Ethernet frame. This enables coexistence of wireless and wired networks and transmission optimization strategies, providing theoretical support and practical guidance for the coexistence of multiple communication networks in the future. Specifically, the second access point AP1 further encapsulates the received second cellular network datagram into an Ethernet frame and uses a byte in the data portion of the Ethernet frame to identify the target user type. Finally, the third access point AP2 forwards the data to mobile users in the area based on the frame identification information, ensuring their communication service quality.

[0074] In step 308, the third access point decapsulates the Ethernet frame to obtain a second cellular network datagram, and encapsulates the second cellular network datagram using the reserved bit through the tunnel encapsulation technology to obtain a second Wi-Fi data frame; the third access point sends the second Wi-Fi data frame to the corresponding user equipment.

[0075] In one embodiment, a multi-communication shared transmission method based on tunnel theory may further include a process of sending an Ethernet frame. The specific process includes: occupying one byte in the data portion of the Ethernet frame to identify the target user type; the third access point searches for a user area based on the target user type and searches for a user device in the user area; and sending a second Wi-Fi data frame to the user device.

[0076] In the cross-LAN LTE / 5G data transmission path selection strategy, such as Figure 2 As shown, in the scenario where network communications are interrupted due to extreme weather (such as a typhoon), the communication link between base station BS2 and third access point AP2 is interrupted, preventing mobile user devices in the area from communicating normally via the unlicensed frequency band. Furthermore, due to the long distance between second base station BS1 and third access point AP2, the quality of communication service for mobile users is difficult to effectively guarantee. To address this issue, a relay-based indirect communication link is designed: second base station BS1 establishes a connection with third access point AP2 using second access point AP1 as a relay node, thereby restoring communication capabilities for mobile users in the area. Specifically, the second access point AP1 encapsulates the received second cellular network datagram into an Ethernet frame and uses a byte in the data portion of the Ethernet frame to identify the target user type. The second access point AP1 then sends the Ethernet frame to the third access point, which decapsulates the Ethernet frame to obtain the second cellular network datagram. The third access point then uses tunnel encapsulation technology to encapsulate the second cellular network datagram using reserved bits to obtain a second Wi-Fi data frame. Finally, the third access point AP2 forwards the second Wi-Fi data frame based on the frame identification information to mobile users in the area, ensuring their communication service quality. This design enables seamless data transmission between heterogeneous networks and ensures efficient data identification and routing during transmission through frame type identification. A reasonable path selection strategy not only optimizes network resource allocation but also alleviates congestion, reduces latency, minimizes data loss, and improves service quality, thereby ensuring user experience and business continuity. This enables seamless data transmission between heterogeneous networks and ensures efficient data identification and routing during transmission through frame type identification. This, in turn, improves data transmission efficiency across local area networks through subsequent path selection strategies.

[0077] This application provides a multi-communication shared transmission method based on tunnel theory. In a local area network environment, the coexistence mechanism of LTE / 5G and Wi-Fi is studied, and a theoretical framework and technical solutions for spectrum sharing and interference management are provided to improve wireless resource utilization and network stability. In the network deployment phase where LTE / 5G and WiFi coexist, a shared transmission mechanism based on tunnel theory is used to embed cellular network data packets into Wi-Fi data frames, enabling LTE / 5G networks to access unlicensed frequency bands, alleviating the problem of limited spectrum resources in licensed frequency bands. This method can be applied to certain specific scenarios, such as high-density crowd environments such as large-scale sports events, concerts, or exhibitions. Limited licensed frequency bands cannot meet the minimum communication service quality for mobile users. In this case, this mechanism can be used to enable LTE / 5G and Wi-Fi networks to coexist fairly, improving the utilization rate of unlicensed spectrum resources while ensuring the service quality of Wi-Fi users. In cross-LAN environments, by studying path optimization methods, efficient data transmission between heterogeneous networks can be achieved, reducing latency and improving overall communication performance. This not only helps to improve the utilization efficiency of network resources, but also significantly improves the user experience, promotes the coordinated development of multiple communication network technologies in a shared spectrum resource environment, and provides theoretical support and practical guidance for future communication architecture optimization and technological evolution.

[0078] The multi-communication shared transmission method based on tunnel theory provided in this application can not only effectively realize the fair coexistence of mobile communications and Wi-Fi in unlicensed frequency bands, but also realize the coexistence between wireless networks and wired networks, improve spectrum utilization efficiency and path transmission optimization strategy, and provide a new solution for the development of coexistence of multiple communication networks.

[0085] In one embodiment, within a local area network, during a shared transmission process within an unlicensed frequency band between a mobile communication network and a Wi-Fi network, time is divided into transmission cycles, wherein each transmission cycle is composed of time resource blocks. A first access point evaluates, based on channel state information, whether the mobile communication network meets the conditions for sharing the unlicensed frequency band. If so, a first base station communicates with the first access point, and the first base station sends a first cellular network datagram corresponding to the user equipment to the first access point.
