Description

Communication methods, devices, systems, equipment and media based on cellular network-free systems

Technical field

The present disclosure relates to the field of communication technology, and in particular, to a communication method, device, system, equipment and medium based on a cellular network-less system.

Background technique

In traditional cellular communication systems, due to the centralized deployment of base stations, there is an obvious edge effect. User signal path losses at the edge of cellular cells are large and they are also susceptible to interference from neighboring cells. The industry has proposed a network system without cellular network, breaking the traditional cellular structure and deploying a large number of APs (Access Points) so that the network has no obvious edge. On the other hand, in traditional TDD (Time Division Duplex) systems, due to the existence of uplink and downlink conversion cycles, the transmission delay is difficult to compress. The industry has proposed a sub-band full-duplex method, which divides the TDD carrier into downlink sub-bands and uplink sub-bands, so that the entire carrier has uplink and downlink resources at the same time, which can effectively shorten the delay. However, it is difficult to effectively isolate the downlink subband and the uplink subband through a large frequency interval like FDD (Frequency Division Duplex), and it is easy to cause cross-link interference, especially interference from base stations to base stations.

For systems without cellular networks, a single AP is usually small, has limited capabilities, and does not have the conditions to separate transmitting and receiving antennas. It is difficult to directly apply subband full-duplex to support the transmission of uplink and downlink data at the same time. Therefore, how to realize simultaneous transmission services of upstream and downstream data in a system without a cellular network to shorten the delay is an urgent technical issue that needs to be solved.

It should be noted that the information disclosed in the above background section is only used to enhance understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to those of ordinary skill in the art.

Example embodiments may, however, be embodied in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concepts of the example embodiments. To those skilled in the art. The described features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar parts, and thus their repeated description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.

To facilitate understanding, before introducing the embodiments of the present disclosure, several terms involved in the embodiments of the present disclosure are first explained as follows:

AP: Access Point, also known as the access node of the wireless network. AP is the core device of a wireless LAN. It mainly includes routing, switching and access integrated devices and pure access point devices. The integrated device performs access and routing work. The pure access device is only responsible for the access of wireless clients. Pure access devices usually Used as a wireless network extension, connect with other APs or the main AP to expand wireless coverage.

TDD: Time Division Duplex, real-time division duplex technology, is a technology used in wireless communication systems. TDD technology allocates the spectrum to uplink and downlink signals in a time division manner to achieve uplink and downlink data transmission. reuse, the frequency band utilization is higher.

FDD: Frequency Division Duplex, which is frequency division duplex technology, is a technology used in wireless communication systems. It divides the channel into an uplink channel and a downlink channel and transmits them on different frequency bands, thereby achieving the separation of uplink and downlink data transmission. , to avoid conflicts between upstream and downstream data.

As mentioned in the aforementioned background art, the transmission delay in the traditional TDD system is difficult to compress due to the existence of uplink and downlink conversion cycles. The industry has proposed a sub-band full-duplex method, which divides the TDD carrier into downlink sub-bands and uplink sub-bands, so that the entire carrier has uplink and downlink resources at the same time, which can effectively shorten the delay. However, it is difficult to effectively isolate the downlink subband and the uplink subband through a large frequency interval like FDD, and it is easy to cause cross-link interference, especially interference from base stations to base stations. For communication systems without cellular networks, a single AP is usually small, has limited capabilities, and does not have the conditions to separate the transmitting and receiving antennas. It is difficult to directly apply subband full-duplex to support simultaneous transmission of uplink data and downlink data.

Therefore, how to apply subband full-duplex technology to systems without cellular networks to reduce latency is an urgent technical issue that needs to be solved.

Specific implementation modes of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a schematic diagram of an exemplary architecture to which a cellular network-less system can be applied in embodiments of the present disclosure. As shown in Figure 1, the cellular network-less system 100 may include a user terminal 101, an AP cluster 102 that provides data transmission services for the user terminal, and an AP cluster processor 103.

The AP cluster 102 includes multiple APs 1021, and each AP 1021 is used to provide data transmission services for the user terminal 101.

The AP cluster processor 103 is used to obtain the data type of the data to be transmitted on the user terminal 101, and according to the data type of the data to be transmitted on the user terminal 101, select from the access point AP cluster 102 of the user terminal 101 to provide the user terminal 101 with the corresponding data type. AP1021 for data transfer services.

It should be noted that the user terminal 101 can be various electronic devices, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, wearable devices, augmented reality devices, virtual reality devices, etc.

The AP cluster processor is a controller used to manage and schedule AP clusters. Its role is to coordinate resource allocation, time synchronization and business management between APs to achieve efficient operation of the entire AP cluster. The AP cluster processor can centrally manage all APs in the AP cluster to achieve centralized control of the entire cluster. It can monitor the health status of all APs, discover new AP nodes, manage collaboration between APs, and adjust the connection methods between APs.

AP cluster is a network organizational structure. Its main feature is to form a cluster of multiple APs in an area to improve network performance and capacity through close collaboration and scheduling. The AP cluster adopts a base station-independent distributed architecture and does not require a centralized controller. Each AP can provide services and control for the network. In an AP cluster, multiple APs can perform either synchronous, efficient transmission or low-latency bidirectional transmission. AP clusters can dynamically adjust the connection methods and port resources between APs according to network load and resource changes, thereby improving network capacity and performance. Compared with traditional base stations, the advantage of AP clusters is that they can minimize the distance and path of signal transmission, thereby improving the speed and stability of the network.

Figure 2 shows a flow chart of a communication method based on a system without a cellular network in an embodiment of the disclosure. As shown in Figure 2, the communication method based on a system without a cellular network provided in the embodiment of the disclosure includes the following steps:

S202: Obtain the data type of the data to be transmitted on the user terminal.

It should be noted that there are various types of data to be transmitted on the user terminal, which can generally be divided into uplink data and downlink data. Uplink data refers to the data sent by the user terminal to the network or server. For example, the user sends a text message on the mobile phone. , upload a picture on the computer or submit a form on the web page, etc.; downstream data refers to the data sent from the network or server to the user terminal, such as playing videos on mobile phones, downloading files on computers or displaying images on web pages, etc.

It should also be noted that the communication system without cellular network in the embodiment of the present disclosure may be a communication system with a cell-free architecture. The cell-free architecture is an emerging wireless communication technology. Compared with traditional cellular networks, Instead of dividing the network into fixed areas (i.e., "cells" or "cells"), all APs are viewed as an integrated architecture, achieving more efficient and flexible communications.

In a traditional cellular network, the network divides the coverage area into many cells, each with a base station. The division between these cells leads to signal interference and insufficient coverage issues, thereby limiting network performance and coverage. However, in a cell-free architecture, all APs can work together, making signal transmission more uniform and efficient.

S204. According to the data type of the data to be transmitted on the user terminal, select an AP that provides corresponding data transmission services for the user terminal from the access point AP cluster of the user terminal. The AP cluster includes: at least one uplink AP and at least one downlink AP. AP, uplink AP is used to provide uplink data transmission services for user terminals, and downlink AP is used to provide downlink data transmission services for user terminals.

It should be noted that there is a wireless communication relationship between the access point AP in the AP cluster and the user terminal. AP is the core device of wireless LAN. It is mainly responsible for providing wireless signals to user terminals, allocating resources, and managing wireless connections, thereby realizing wireless network connections for user terminals. In practical applications, a user terminal needs to be connected to one or more APs. The user terminal can communicate with the network or server through the access point AP to realize data transmission and interaction.

AP cluster refers to a wireless LAN system composed of multiple APs. In wireless communication applications, in order to cover a wider area and provide better service quality, multiple AP devices are set up to cover signals in a physical area, thereby forming an AP cluster to provide a better user experience.

In the embodiment of the present disclosure, the AP cluster consists of at least one uplink AP and at least one downlink AP. The uplink AP is used to provide uplink data transmission services for user terminals, and the downlink AP is used to provide downlink data transmission services for user terminals. User terminals can select the best data transmission path through these APs to improve the efficiency and quality of data transmission.

In an AP cluster, AP devices cooperate with each other to coordinate resource allocation and wireless signal management to ensure the stability and reliability of the entire cluster. At the same time, AP devices in the AP cluster can support seamless roaming, maintaining the stability and continuity of network connections when the user terminal moves from one AP device to another, thereby providing users with a better network experience. .

In the embodiment of the present disclosure, the data type of the data to be transmitted on the user terminal is obtained; according to the data type of the data to be transmitted on the user terminal, an AP cluster that provides corresponding data transmission services for the user terminal is selected from the access point AP cluster of the user terminal. AP, wherein the AP cluster includes: at least one uplink AP and at least one downlink AP. The uplink AP is used to provide uplink data transmission services for user terminals, and the downlink AP is used to provide downlink data transmission services for user terminals. Under the cellular network-free system architecture of the present disclosure, the AP has uplink and downlink resources, which avoids cross-link interference, effectively shortens the transmission delay, and improves the transmission service quality for user terminals.

The personal identity data and operations related to individuals, customers, and groups obtained in the embodiments of this disclosure are Various types of data, including data and behavioral data, have been authorized.

In some embodiments of the present disclosure, Figure 3 shows a flow chart of yet another communication method based on a non-cellular network system of the present disclosure. As shown in Figure 3, the method also includes the following steps:

S302: Obtain the AP cluster of the user terminal, where the AP cluster includes multiple APs that provide data transmission services for the user terminal.

It should be noted that the user terminal and the AP cluster are connected through a wireless network. When the user terminal accesses the AP cluster, it can use the wireless local area network of the AP cluster for data transmission and communication. The AP cluster includes: providing data transmission services for the user terminal. of multiple APs.

S304: Configure multiple APs in the AP cluster to obtain an uplink AP that provides uplink data transmission services for user terminals and a downlink AP that provides downlink data transmission services for user terminals.

It should be noted that the APs in the AP cluster in the embodiment of the present disclosure have been configured in advance, and the resulting AP cluster includes uplink APs that provide uplink data transmission services for user terminals and downlink APs that provide downlink data transmission services for user terminals. . Generally, APs that provide uplink data transmission services for user terminals need to be used to transmit user data packets to the network. Their transmission rate, signal quality and stability need to be optimized, the uplink bandwidth should be appropriately increased, and the delay should be reduced as much as possible. The AP that provides downlink data transmission services for user terminals needs to be used to receive data packets sent by the server. It needs to optimize its transmission rate, signal quality and stability, appropriately increase the downlink bandwidth, and also reduce the delay as much as possible. Specific configurations can be achieved through different network management tools, software or instructions.

According to the method provided by the embodiments of the present disclosure, the AP cluster can be configured with uplink APs that provide uplink data transmission services for user terminals and downlink APs that provide downlink data transmission services for user terminals, thereby achieving stable transmission of network data.

In some embodiments of the present disclosure, Figure 4 shows a configuration method of an AP cluster. As shown in Figure 4, multiple APs in the AP cluster are configured to obtain an uplink data transmission service for user terminals. APs and downlink APs that provide downlink data transmission services for user terminals include the following steps:

S402. Configure the frame format cycle of each AP in the AP cluster as all uplink time slots, all downlink time slots, and subband full duplex time slots. The all uplink time slots are the time slots that only include uplink subcarriers in the frame format cycle. The full downlink time slot is a time slot that only contains downlink subcarriers in the frame format period. The subband full duplex time slot is a time slot that contains both uplink subcarriers and downlink subcarriers in the frame format period. The uplink subcarrier is the transmission The subcarriers for uplink data and the downlink subcarriers are the subcarriers for transmitting downlink data.

It should be noted that the frame format period refers to a sequence of subcarriers and time slots, and data is transmitted through subcarriers. In this configuration, the frame format period configuration of each AP in the AP cluster includes all uplink time slots, all downlink time slots, and subband full-duplex time slots. Among them, the full uplink time slot only contains uplink subcarriers and is used to transmit uplink data; the full downlink time slot only contains downlink subcarriers and is used to transmit downlink data; the subband full duplex time slot contains both uplink subcarriers and downlink subcarriers. , the uplink subcarrier is used to transmit uplink data, and the downlink subcarrier is used to transmit downlink data.

For a single AP, the frame format period will be configured as three different types of time slots. When a single AP serves as an uplink AP for user terminals to provide uplink data transmission services, the subband full-duplex time slots in the frame format period will be It is only used to transmit uplink data. Similarly, when a single AP serves as a downlink AP for user terminals to provide uplink data transmission services, the subband full-duplex time slot in the frame format cycle is only used to transmit downlink data. When an uplink AP and an When the downlink AP serves the same user terminal, full duplex subbands are achieved.

S404: Configure the subband full-duplex time slots of the APs in the AP cluster that provide uplink data transmission services to only use uplink subcarriers to transmit data, thereby obtaining an uplink AP that provides uplink data transmission services for user terminals.

S406: Configure the subband full-duplex time slots of the APs in the AP cluster that provide downlink data transmission services to only use downlink subcarriers to transmit data, thereby obtaining a downlink AP that provides downlink data transmission services for user terminals.

It should be noted that Figure 5 shows a schematic diagram of the AP frame format. As shown in Figure 5, the frame format of the AP according to the embodiment of the present disclosure is configured as a full downlink time slot 501, a subband full duplex time slot 502, and a full uplink time slot. Slot 503, in which the full uplink time slot 503 only contains uplink subcarriers and is used to transmit uplink data; the full downlink time slot 501 only contains downlink subcarriers and is used to transmit downlink data; the subband full duplex time slot 502 also contains uplink subcarriers. Carrier and downlink subcarrier, the uplink subcarrier is used to transmit uplink data, and the downlink subcarrier is used to transmit downlink data.

The AP can normally use the entire carrier to work in all uplink time slots 503 and all downlink time slots 501. When the AP serves as a downlink AP, as shown in Figure 6, the subband full-duplex time slot 502 only transmits data on the downlink subcarrier; when the AP serves as an uplink AP, as shown in Figure 7, when the subband full-duplex time slot 502 Slot 502 only performs data transmission on the uplink subcarrier.

In addition, it should be explained that Figure 8 shows a schematic structural diagram of the AP in the embodiment of the present disclosure. As shown in Figure 8, the AP consists of a processor 801, an uplink 802, a downlink 803 and a set of antennas 804. Since each AP only has one set of antennas, only uplink or downlink communication can be performed at the same time. Uplink and downlink switching are performed according to the time division multiplexing principle. It can make full use of channel resources, improve channel utilization, and avoid mutual interference and collision between uplink and downlink communications, thereby ensuring communication quality.

Under the AP frame format periodic configuration of the embodiment of the present disclosure, a single AP has uplink and downlink resources through the time division multiplexing principle, and can independently maintain data transmission with user terminals. In addition, through uplink AP and downlink AP collaboration to serve the same user terminal, This enables user terminals to have uplink and downlink resources at the same time, realizing full-duplex subbands without cellular networks.

In some embodiments of the present disclosure, Figure 9 shows the communication method of the first data type of the present disclosure. As shown in Figure 9, according to the data type of the data to be transmitted on the user terminal, from the access point AP of the user terminal Selecting APs in the cluster that provide corresponding data transmission services for user terminals includes the following steps:

S902: Obtain the distance between the user terminal and each AP in the AP cluster.

S904: Determine the AP in the AP cluster that is closest to the user terminal as the AP that provides data transmission services for the user terminal to transmit data of the first data type on the user terminal.

It should be noted that there are various data types for obtaining data to be transmitted on the user terminal, one of which is the first data type, and the first data type is that the amount of data to be sent or received on the user terminal is less than the preset data amount threshold. The data type, the preset data amount is the set data amount value. When the amount of data to be sent or received is less than this threshold, the data type is determined to be the first data type, and the corresponding user terminal can be understood as The user terminal is a user terminal with low performance and low requirements.

At this time, the distance between the user terminal and each AP in the AP cluster serving the user terminal is obtained, and the AP in the AP cluster that is closest to the user terminal is determined as the AP that provides data transmission services for the user terminal to transmit the first A data type of data.

It should be understood that the nearest AP is an AP configured with a frame format period and can transmit uplink and downlink data.

In some embodiments of the present disclosure, Figure 10 shows the communication method of the second data type of the present disclosure. As shown in Figure 10, according to the data type of the data to be transmitted on the user terminal, from the access point AP of the user terminal Selecting APs in the cluster that provide corresponding data transmission services for user terminals includes the following steps:

S1002: Obtain the distance between the user terminal and each AP in the AP cluster.

S1004: Use at least one downlink AP in the AP cluster that meets the first preset distance condition as an AP that provides data transmission services for the user terminal to transmit data of the second data type on the user terminal.

It should be noted that the second data type is a data type in which the delay of the downlink data to be transmitted on the user terminal is greater than the preset delay threshold. The preset delay threshold is a set time value. When the delay of the downlink data to be transmitted is When it is greater than the preset delay threshold, the data type is determined to be the second data type, and the corresponding user terminal can be understood as a delay-insensitive downlink terminal. For specific examples, the second data type can be: asynchronous transmission Data, streaming data, etc., where data is transferred asynchronously. This type of data transfer does not require a real-time response, such as emails, file downloads, etc. Business types such as streaming media data do not have high latency requirements, such as audio and video streaming.

When the data type is the second data type, the distance between the user terminal and each AP in the AP cluster serving the user terminal is obtained, and at least one downlink AP in the AP cluster that meets the first preset distance condition is used as the user terminal to provide data The AP of the transmission service is used to transmit data of the second data type on the user terminal.

The first preset distance condition is a distance condition set in advance. Specifically, it may be that at least one nearest AP is used as the main AP and several other nearby downlink APs are combined to serve the user terminal.

In some embodiments of the present disclosure, when the delay-insensitive downlink user terminal is close to the uplink sub-band AP, it can also access the uplink sub-band AP to obtain uplink data transmission services if the downlink capacity permits.

In some embodiments of the present disclosure, Figure 11 shows the communication method of the third data type of the present disclosure. As shown in Figure 11, according to the data type of the data to be transmitted on the user terminal, from the access point AP of the user terminal Selecting APs in the cluster that provide corresponding data transmission services for user terminals includes the following steps:

S1102: Obtain the distance between the user terminal and each AP in the AP cluster.

S1104: Use at least one uplink AP in the AP cluster that meets the second preset distance condition as an AP that provides data transmission services for the user terminal to transmit data of the third data type on the user terminal.

It should be noted that the third data type is a data type in which the delay of the uplink data to be transmitted on the user terminal is greater than the preset delay threshold. The preset delay threshold is a set time value. When the delay of the downlink data to be transmitted is When it is greater than the preset delay threshold, the data type is determined to be the third data type, and the corresponding user terminal can be understood as a delay-insensitive uplink terminal. The following example is used for reference:

Such as home smart home: Home smart home devices usually need to report usage data to the cloud, such as power usage, air quality, etc. These data are third-party data and generally do not require real-time response and are not sensitive to delay.

Webcam: The webcam uploads the video stream to the cloud for processing. The video stream data is the third data. The user terminal is a delay-insensitive uplink terminal.

When the data type is the third data type, the distance between the user terminal and each AP in the AP cluster serving the user terminal is obtained, and at least one uplink AP in the AP cluster that meets the second preset distance condition is used as the user terminal to provide data The AP of the transmission service is used to transmit data of the third data type on the user terminal.

The second preset distance condition is a distance condition set in advance, which can be the same as the first preset distance value. This only represents the distinction. Specifically, it can be that at least one of the nearest uplink APs is used as the main AP, and other closer APs are used. Several uplink APs jointly serve the user terminal.

In some embodiments of the present disclosure, when the delay-insensitive uplink user terminal is close to the downlink sub-band AP, it can also access the downlink sub-band AP to obtain downlink data transmission services if the uplink capacity allows.

In some embodiments of the present disclosure, Figure 12 shows the communication method of the fourth data type of the present disclosure. As shown in Figure 12, according to the data type of the data to be transmitted on the user terminal, from the access point AP of the user terminal Selecting APs in the cluster that provide corresponding data transmission services for user terminals includes the following steps:

S1202: Obtain the distance between the user terminal and each AP in the AP cluster.

S1204: Use at least one uplink AP and at least one downlink AP in the AP cluster that meet the third preset distance condition as APs that provide data transmission services for the user terminal to transmit data of the fourth data type on the user terminal.

It should be noted that the fourth data type is a data type in which the delay of the uplink data and/or downlink data to be transmitted on the user terminal is less than the preset delay threshold. The preset delay threshold is a set time value. When the user terminal When the delay of uplink data and/or downlink data to be transmitted is less than the preset delay threshold, the data type is determined to be the fourth data type, and the corresponding user terminal can be understood to be a delay-sensitive terminal, that is, for User terminal devices that are very sensitive to network latency and require real-time response, such as remote control robots: Remote control robots need to respond to the operator's instructions in real time to ensure the stability and security of remote control. This data type is the fourth data type, and the corresponding user terminal is very sensitive to delay response. Video conferencing terminal: Video conferencing terminal requires real-time transmission of high-definition video and audio signals to ensure smooth interaction. If the network delay exceeds a certain order of magnitude, it is easy to cause video and audio delays and desynchronization. Online game terminal: Online game terminal needs to respond to the player's operating instructions in real time to ensure the smoothness of the game. If the delay is too high, the game will not be able to play, which will seriously affect the player's gaming experience.

For delay-sensitive terminal applications, that is, the fourth data type data to be transmitted, it is usually necessary to respond to changes in the network in the shortest time. This type of terminal equipment requires the use of full-duplex subband transmission mode to ensure that two-way data transmission is completed within a certain period of time. In this regard, the distance between the user terminal and each AP in the AP cluster is obtained, and at least one uplink AP and at least one downlink AP in the AP cluster that meet the third preset distance condition are used as APs that provide data transmission services for the user terminal to transmit data on the user terminal. Data of the fourth data type. By having both uplink AP and downlink AP serving the same user terminal, full-duplex is achieved, which can minimize the delay and achieve the best network performance.

In some embodiments of the present disclosure, APs in the above-mentioned AP cluster can be deployed closely to avoid the problem of coverage weakening after the uplink and downlink separation of sub-band full-duplex time slots. When the data type to be transmitted in the AP cluster does not have the fourth data type, that is, when there are no delay-sensitive terminals in the AP cluster, the sub-band full-duplex time slot of the AP can be changed to a full uplink time slot and a full downlink time slot. When the data type to be transmitted in the AP cluster is the fourth data type, that is, when there are delay-sensitive terminals in the AP cluster, the AP frame format period is configured to have subband full-duplex time slots, and the AP's transmission is increased accordingly. power. In this process, the uplink and downlink subband ownership of a single AP and the uplink and downlink subband division ratio within the cluster can be adjusted according to the load of each AP. However, there must be both uplink and downlink subband APs near delay-sensitive terminals. If APs in a contiguous area all belong to subbands in the same direction, APs in the area that are far away from adjacent subband APs can expand their subband width accordingly to improve overall network capacity and performance.
