Description

Technical Field

[0001] The present invention relates to the technical field of communication engineering, and in particular to a multi-communication shared transmission method and system based on tunnel theory. Background Art

[0002] With the rapid development of information technology, modern communication systems have become highly diversified and complex. Heterogeneous networks such as mobile communications, wireless local area networks, and Ethernet each operate in different frequency bands and use different protocols to meet diverse application requirements. However, with the evolution of mobile communication technology, its business model has shifted from traditional voice communications to data services. In particular, with the gradual popularization of 5G networks and the widespread application of smart terminals, mobile data traffic has grown exponentially, and the access layer needs to carry large-scale concurrent connections. At present, mobile network services cover multiple scenarios such as web browsing, instant messaging, social networks, e-commerce, video streaming, and online games, and are deeply integrated into people's daily lives. As an important driving force for the evolution of the Internet, mobile Internet services have not only reshaped traditional communication models, but also spawned new business forms and achieved sustainable development. In addition, the evolution of user communication behavior and the popularization of smart terminals have further intensified the dependence on network resources and promoted the growth of demand for new communication resources. At the same time, emerging fields such as wearable devices, smart cities, smart medical care, Internet of Vehicles, and machine communications have put forward higher requirements for networks. These changes have made the efficient coexistence of multiple communication systems in complex network environments a core issue that needs to be solved urgently. In modern communication systems, the coexistence and transmission optimization of multiple communication systems have become key research directions, 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 (cross-local area network environment). This issue not only involves the efficient sharing and coordination of spectrum resources, but also covers the optimization and management of transmission paths. With the continuous expansion of network scale and the increasing demand of users for high-quality communication services, how to achieve harmonious coexistence and efficient transmission of heterogeneous communication systems in complex network environments has become a hot topic and difficulty in current research.

[0003] At present, some methods have been proposed to achieve coexistence of mobile communication systems and wireless communication systems in unlicensed frequency bands. For example, the CSAT mechanism introduced by Qualcomm in LTE base stations achieves fair coexistence of Wi-Fi and LTE-U by adjusting the duty cycle; the LTE-LAA solution based on the LBT mechanism designed by 3GPP uses channel energy detection for access control. However, these methods have many problems. The solution based on the CSAT mechanism faces challenges in determining the optimal duty cycle, and the existing coexistence solutions still need to be improved in fairness and spectrum utilization efficiency; the LBT mechanism varies in different regions and has technical limitations, and the current mainstream CSAT and LBT mechanisms are mostly controlled by the LTE system, which may seriously affect the performance of the Wi-Fi system when optimizing LTE performance. However, 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, traditional multi-communication systems often have low transmission efficiency and low network resource utilization, resulting in poor overall communication performance. Summary of the invention

[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying 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 is understood that the terms "first", "second", etc. used in this application may be used herein to describe access points, cellular network datagrams, and Wi-Fi data frames, but these access points, cellular network datagrams, and Wi-Fi data frames are not limited by these terms. These terms are only used to distinguish a first access point, a cellular network datagram, and a Wi-Fi data frame from another access point, a cellular network datagram, and a Wi-Fi data frame. For example, without departing from the scope of this application, a first access point may be referred to as a second access point, and similarly, a second access point may be referred to as a first access point. Both the first access point and the second access point are access points, but they are not the same access point.

[0051] The multi-communication shared transmission method based on tunnel theory provided in the embodiment of the present application can be applied to Figure 1 , Figure 2 In the application environment shown. Figure 1 , Figure 2 As shown in FIG, the application environment includes a coexistence system of mobile communication and Wi-Fi within a local area network, and a coexistence system of mobile communication and Ethernet across local area networks. Figure 1 As shown in the figure, in the coexistence system of mobile communication and Wi-Fi in the local area network, the Wi-Fi system includes: access point (AP) and multiple stations (STAs), and the mobile communication system includes base station (BS) and multiple user equipments (UEs); when transmitting in the unlicensed frequency band, the uplink of the mobile communication system uses the licensed frequency band, and the downlink shares the unlicensed frequency band with the Wi-Fi system. Figure 2 As shown, the inter-LAN mobile communication and Ethernet coexistence system includes multiple APs and multiple STAs as well as BS and multiple UEs, and routers required for Ethernet transmission.

[0052] In one embodiment, Figure 3 As shown, a multi-communication shared transmission method based on tunnel theory is provided, comprising the following steps:

[0053] Step 302, before the data transmission cycle starts, the first base station in the local area network sends channel state information, time resource block requirements, and a first cellular network datagram to the first access point, and the first access point calculates a time resource block allocation strategy based on the channel state information and the time resource block requirements.

[0054] During the shared transmission process between the mobile communication network LTE / 5G and the Wi-Fi network in the unlicensed frequency band within the local area network, before the start of each transmission cycle, the first base station and the first access point exchange information to collaboratively share channel state information and time resource block requirements. The SDN controller at the first access point end evaluates whether the mobile communication network has the conditions for sharing the unlicensed spectrum based on the received channel state information, and calculates the optimal time resource block allocation strategy.

[0055] In one embodiment, a multi-communication shared transmission method based on tunnel theory is provided, which may also include a process of dividing transmission cycles and determining whether conditions for sharing frequency bands are met. The specific process includes: in a local area network, during shared transmission between a mobile communication network and a Wi-Fi network in an unlicensed frequency band, time is divided into transmission cycles; wherein each transmission cycle is composed of time resource blocks; a first access point evaluates whether the mobile communication network has conditions for sharing an unlicensed frequency band based on channel state information; if so, the 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.

[0056] During the shared transmission process between the mobile communication network LTE / 5G and the Wi-Fi network in the unlicensed frequency band within the local area network, the time can be divided into multiple transmission cycles, each cycle consists of R time resource blocks, expressed as r={1, 2, ..., R}.

[0057] Specifically, in one embodiment, a multi-communication shared transmission method based on tunnel theory may also include a process for determining whether conditions for sharing a frequency band are met, and the specific process includes: the first access point determines whether there are idle channel resources in the unlicensed frequency band of the Wi-Fi network based on the channel state information; if there are idle channel resources, it is determined whether the channel resources of the mobile communication network in the licensed frequency band can meet the time resource block requirements corresponding to the user equipment; if the time resource block requirements can be met, the mobile communication network meets the conditions for sharing the unlicensed frequency band.

[0058] That is, in this embodiment, the basic conditions for the coexistence of the mobile communication network LTE / 5G and the Wi-Fi network include: first, the Wi-Fi network has underutilized channel resources in the unlicensed frequency band; second, the resources of the mobile communication network LTE / 5G in the licensed spectrum are no longer sufficient to meet the needs of the user equipment UE.

[0059] When the basic conditions for the 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 to transmit the mobile signal data frame and related information required by the user equipment UE to the first access point AP.

[0060] Step 304: The first access point encapsulates the first cellular network datagram using the reserved bit through the 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 strategy.

[0061] In a network where LTE / 5G and Wi-Fi coexist, since both operate independently in unlicensed frequency bands and need to compete for channel resources, conflicts may increase, thus 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 cellular network datagrams through Wi-Fi APs, so that cellular network datagrams can be transmitted on unlicensed channels in the form of Wi-Fi data frames.

[0062] In one embodiment, a multi-communication shared transmission method based on tunnel theory may further include a process of performing data encapsulation, wherein the specific process includes: the first access point uses a tunnel encapsulation technology to use a cellular network datagram as a payload, and uses a reserved bit to encapsulate the cellular network datagram in an initial data frame; obtains a frame header and a frame trailer of a MAC frame, and adds the frame header and the frame 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 strategy, the process also includes: the user device parses the frame header of the first Wi-Fi data frame, identifies and restores the original data.

[0063] Among them, Figure 4 As shown, the first access point AP uses the tunnel encapsulation technology to take the mobile communication data frame, i.e., the first cellular network datagram, as the payload of the Wi-Fi data frame, and combines the MAC frame header and frame tail of IEEE 802.11 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 in 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, a multi-communication shared transmission method based on tunnel theory may also include a process of defining reserved bits to distinguish data frames, the specific process including: when the first access point sends regular data to other sites, using a first field combination in the reserved bits; when the first access point sends mobile communication data to a user device, using a second field combination in the reserved bits; encapsulating the first field combination or the second field combination in combination with a cellular network datagram in an initial data frame.

[0066] Among them, in the tunnel transmission mechanism, the Type and Subtype combination in the IEEE 802.11MAC frame structure is used to distinguish mobile communication data frames from Wi-Fi data frames by redefining reserved bits. Specifically, when the Wi-Fi AP sends a regular data frame, the Type and Subtype combination uses "100000", and when the AP sends a mobile communication data frame, the "100001" combination is used, and the mobile communication data is encapsulated into the Wi-Fi data frame through tunnel encapsulation technology, so that the UE can correctly parse and restore the original data. In this embodiment, the frame header information is extended to enable the UE and STA to accurately identify the source and type of the received data.

[0067] In one embodiment, a multi-communication shared transmission method based on tunnel theory may further include a resource allocation process, wherein the specific process includes: the first access point calculates a resource allocation scheme according to a time resource block allocation strategy; determines a target time resource block based on the resource allocation scheme; and sends a first Wi-Fi data frame to a user device within 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 a Wi-Fi frame encapsulated with mobile communication data to the corresponding UE, and the UE identifies the data type by parsing the frame header and receives and processes it.

[0069] In one embodiment, Figure 1 As shown, the tunnel transmission mechanism 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. In this embodiment, the UE directly receives the first cellular network datagram 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.

[0070] like Figure 1As shown, in the 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, and the second access point encapsulates the second cellular network datagram into an Ethernet frame and sends it 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 Ethernet frames, and the specific process includes: 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, in the network deployment stage where LTE / 5G and Ethernet coexist, the shared transmission mechanism based on tunnel theory embeds the second cellular network datagram into the Wi-Fi data frame, and then embeds it into the Ethernet frame when it is transmitted through the wired network, which can realize the coexistence and transmission optimization strategy of wireless network and wired network, and provide theoretical support and practical guidance for the coexistence between 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 occupies one byte in the data part of the Ethernet frame to identify the target user type; finally, the third access point AP2 forwards the data to the mobile users in the area according to the frame identification information to ensure their communication service quality.

[0074] 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 a reserved bit through a 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 also include a process of sending an Ethernet frame, and the specific process includes: occupying one byte in the data part of the Ethernet frame to identify the target user type; the third access point searches for a user area according to the target user type, and searches for a user device in the user area; and sends 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 communication is interrupted due to extreme weather (such as typhoon), the communication link between the base station BS2 and the third access point AP2 is interrupted, so that the mobile user devices in the area cannot achieve normal communication through the unlicensed frequency band. At the same time, due to the long distance between the second base station BS1 and the third access point AP2, the communication service quality of mobile users is difficult to be effectively guaranteed. In order to solve the above problem, an indirect communication link based on relay is designed: the second base station BS1 establishes a connection with the third access point AP2 through the second access point AP1 as a relay node, thereby restoring the communication capability of mobile users in the area. Specifically, the second access point AP1 encapsulates the received second cellular network datagram into an Ethernet frame, and occupies a byte in the data part of the Ethernet frame to identify the target user type; then, the second access point AP1 sends the Ethernet frame to the third access point, the third access point decapsulates the Ethernet frame, obtains the second cellular network datagram, and encapsulates the second cellular network datagram using the reserved bit through the tunnel encapsulation technology to obtain the second Wi-Fi data frame; finally, the third access point AP2 forwards the second Wi-Fi data frame to the mobile users in the area according to the frame identification information to ensure the quality of their communication service. This design realizes seamless data transmission between heterogeneous networks, and ensures efficient identification and routing of data during transmission through frame type identification. Reasonable path selection strategy can not only optimize network resource allocation, but also alleviate congestion, reduce latency, reduce data loss, and improve service quality, thereby ensuring user experience and business continuity; it can realize seamless data transmission between heterogeneous networks, and ensure efficient identification and routing of data during transmission through frame type identification, and improve data transmission efficiency across local area networks through subsequent path selection strategies.

[0077] A multi-communication shared transmission method based on tunnel theory provided in this application studies the coexistence mechanism of LTE / 5G and Wi-Fi in a local area network environment, and provides a theoretical framework and technical solution for spectrum sharing and interference management to improve wireless resource utilization and network stability; in the network deployment stage where LTE / 5G and WiFi coexist, a shared transmission mechanism based on tunnel theory is used to embed cellular network datagrams into Wi-Fi data frames, so that LTE / 5G networks can 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. The limited licensed frequency bands cannot meet the minimum communication service quality of mobile users. At this time, this mechanism can be used to enable LTE / 5G and Wi-Fi networks to coexist fairly, and improve the utilization rate of unlicensed spectrum resources while ensuring the service quality of Wi-Fi users. In a cross-LAN environment, by studying path optimization methods, efficient data transmission between heterogeneous networks can be achieved, latency can be reduced and overall communication performance can be improved. This not only helps to improve the utilization efficiency of network resources, but also significantly improves 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] A multi-communication shared transmission method based on tunnel theory provided in this application can not only effectively realize the fair coexistence of mobile communication 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.
