Description

Communication method, device, system, equipment and medium based on non-cellular network system

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a communication method, apparatus, system, device, and medium based on a cellular network-free system.

Background

In the traditional cellular communication system, due to the centralized deployment of base stations, obvious edge effects exist, and the user signal path loss at the cell edge is large and is also easy to be interfered by neighbor cells. The industry proposes a network system without a cellular network, breaks through the traditional cellular structure, and enables the network to have no obvious edge by deploying a large number of APs (Access points). On the other hand, in the conventional TDD (Time Division Duplex ) system, transmission delay is difficult to compress due to the existence of the uplink-downlink switching period. The industry proposes a full duplex method of a sub-band, and the TDD carrier is divided into a downlink sub-band and an uplink sub-band, so that the whole carrier has uplink and downlink resources at the same time, and the time delay can be effectively shortened. However, it is difficult to effectively isolate the downlink sub-band and the uplink sub-band with a large frequency interval as in FDD (Frequency Division Duplex ), and cross link interference, especially interference from a base station to a base station, is likely to occur.

For a system without a cellular network, a single AP is usually smaller and has limited capability, and has no condition of separating a receiving antenna and a transmitting antenna, so that it is difficult to directly apply full duplex of a sub-band to realize simultaneous support of uplink data and downlink data transmission. Therefore, how to realize the transmission service of up-down data in a cellular network-free system so as to realize the shortening of the time delay is a technical problem to be solved.

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

However, the exemplary embodiments may be embodied in many 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 concept 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 denote the same or similar parts, and thus a repetitive description thereof 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. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.

For ease of understanding, before describing embodiments of the present disclosure, several terms referred to in the embodiments of the present disclosure are first explained as follows:

AP: access Point, an Access Point, is also known as an Access node of a wireless network. The AP is a core device of a wireless local area network, and mainly comprises a route switching access integrated device and a pure access point device, wherein the integrated device performs access and route work, the pure access device is only responsible for the access of a wireless client, and the pure access device is usually used as a wireless network expansion and is connected with other APs or a main AP to expand wireless coverage.

TDD: time Division Duplex, i.e. the time division duplex technology, is a technology applied to a wireless communication system, and the TDD technology distributes spectrum to signals in uplink and downlink directions to divide the signals in a time division manner, so as to realize multiplexing of uplink and downlink data transmission, and the frequency band utilization rate is higher.

FDD: frequency Division Duplex, namely frequency division duplexing technology, is a technology applied to a wireless communication system, and divides a channel into an uplink channel and a downlink channel and transmits the uplink channel and the downlink channel on different frequency bands, so that separation of uplink and downlink data transmission is realized, and collision of uplink and downlink data is avoided.

As mentioned in the foregoing background art, in the conventional TDD system, transmission delay is difficult to compress due to the existence of the uplink-downlink switching period. The industry proposes a full duplex method of a sub-band, and the TDD carrier is divided into a downlink sub-band and an uplink sub-band, so that the whole carrier has uplink and downlink resources at the same time, and the time delay can be effectively shortened. However, it is difficult to effectively isolate the downlink sub-band and the uplink sub-band with a large frequency interval as in FDD, and cross link interference, particularly interference from a base station to a base station, is likely to occur. For a communication system without a cellular network, a single AP is generally smaller and has limited capability, and has no condition of separating a receiving antenna and a transmitting antenna, so that it is difficult to directly apply full duplex of a sub-band to realize supporting simultaneous transmission of uplink data and downlink data.

Therefore, how to apply the sub-band full duplex technology to the non-cellular network system to achieve the time delay shortening is a technical problem to be solved.

The following detailed description of embodiments of the present disclosure refers to the accompanying drawings.

Fig. 1 shows an exemplary architecture diagram of a non-cellular network system to which embodiments of the present disclosure may be applied. As shown in fig. 1, the cellular-free network system 100 may include a user terminal 101, an AP cluster 102 providing a data transmission service for the user terminal, and an AP cluster processor 103.

The AP cluster 102 includes a plurality of APs 1021, and each AP1021 is configured to provide a data transmission service for the user terminal 101.

The AP cluster processor 103 is configured to obtain a data type of data to be transmitted on the user terminal 101, and select, from the AP clusters 102 of the access points of the user terminal 101, an AP1021 providing a corresponding data transmission service for the user terminal 101 according to the data type of the data to be transmitted on the user terminal 101.

It should be noted that the user terminal 101 may be various electronic devices, including but not limited to a smart phone, a tablet computer, a laptop portable computer, a desktop computer, a wearable device, an augmented reality device, a virtual reality device, and the like.

An AP cluster processor is a controller for managing and scheduling AP clusters. The method has the function of coordinating resource allocation, time synchronization and service management among the APs so as to realize efficient operation of the whole AP cluster. The AP cluster processor can intensively manage all APs in the AP cluster, so that the centralized control of the whole cluster is realized. It can monitor the health status of all APs, discover new AP nodes, manage collaboration among APs, and adjust the connection between APs, etc.

The AP cluster is a network organization structure and is mainly characterized in that a plurality of APs in an area form a cluster, and network performance and capacity are improved through close cooperation and scheduling. The AP cluster adopts a distributed architecture irrelevant to the base station, and a centralized controller is not needed, so that each AP can provide services and control for the network. In an AP cluster, multiple APs may be efficiently transmitted synchronously or bi-directionally transmitted with low delay. The AP cluster can dynamically adjust the connection mode and port resources between the APs according to the network load and resource change, thereby improving the capacity and performance of the network. The AP cluster has an advantage in that the distance and path of signal transmission can be reduced to the maximum extent compared with the conventional base station, thereby improving the speed and stability of the network.

Under the system architecture described above, embodiments of the present disclosure provide a communication method based on a cellular-free network system, which may be performed by any electronic device having computing processing capabilities.

In some embodiments, the communication method based on the cellular network-free system provided in the embodiments of the present disclosure may be performed by a user terminal of the above system architecture; in other embodiments, the communication method based on the cellular-free network system provided in the embodiments of the present disclosure may be performed by a server; in other embodiments, the communication method based on the cellular network-free system provided in the embodiments of the present disclosure may be implemented by the user terminal and the server in the system architecture in an interactive manner.

Fig. 2 shows a flowchart of a communication method based on a cellular network-free system in an embodiment of the disclosure, and as shown in fig. 2, the communication method based on the cellular network-free system provided in the embodiment of the disclosure includes the following steps:

s202, obtaining the data type of the data to be transmitted on the user terminal.

It should be noted that the types of data to be transmitted on the user terminal are various and can be generally divided into uplink data and downlink data, wherein the uplink data refers to data sent to a network or a server by the user terminal, for example, a user sends a short message on a mobile phone, uploads a picture on a computer or submits a form on a webpage, etc.; downstream data refers to data sent from a network or server to a user terminal, such as playing video on a mobile phone, downloading a file on a computer, displaying an image in a web page, etc.

It should also be noted that the non-cellular communication system in the embodiments of the present disclosure may be specifically a communication system with a cell-free architecture, which is an emerging wireless communication technology, and compared to a conventional cellular network, the cell-free architecture does not divide the network into fixed areas (i.e. "cells" or "cells"), but considers all APs as an integrated architecture, so as to achieve more efficient and flexible communication.

In a conventional cellular network, the network divides the coverage area into a number of cells, each with a base station. The division between these cells causes problems of signal interference and insufficient coverage, limiting network performance and coverage. However, in the cell-free architecture, all APs can work cooperatively, thereby making signal transmission more uniform and efficient.

It should be noted that, a relationship between an access point AP and a user terminal in an AP cluster is a wireless communication relationship. The AP is core equipment of the wireless local area network and is mainly responsible for providing wireless signals, distributing resources, managing wireless connection and other functions for the user terminal, so that the wireless network connection of the user terminal is realized. In practical application, one user terminal needs to have one or more APs connected with the user terminal, and the user terminal can communicate with a network or a server through the AP to realize data transmission and interaction.

An AP cluster refers to a wireless local area network system composed of a plurality of APs. In wireless communication applications, to cover a wider area and provide better quality of service, multiple AP device coverage signals are set in one physical area, thereby forming an AP cluster to provide better user experience.

In the embodiment of the disclosure, the AP cluster is composed of at least one uplink AP and at least one downlink AP. The uplink AP is used for providing uplink data transmission service for the user terminal, and the downlink AP is used for providing downlink data transmission service for the user terminal. The user terminal can select the optimal data transmission path through the APs so as to improve the efficiency and quality of data transmission.

In one AP cluster, AP devices cooperate with each other to coordinate resource allocation and wireless signal management together, so that stability and reliability in the whole cluster are ensured. Meanwhile, the AP equipment in the AP cluster can support seamless roaming, and stability and continuity of network connection are maintained in the process that the user terminal moves from one AP equipment to another AP equipment, so that better network experience is provided for the user.

In the embodiment of the 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, selecting an AP for providing corresponding data transmission service for the user terminal from an AP cluster of an access point of the user terminal, wherein the AP cluster comprises: at least one uplink AP and at least one downlink AP, wherein the uplink AP is used for providing uplink data transmission service for the user terminal, and the downlink AP is used for providing downlink data transmission service for the user terminal.

It should be noted that, in the technical solution of the present disclosure, the acquiring, storing, using, processing, etc. of data all conform to relevant regulations of national laws and regulations, and various types of data such as personal identity data, operation data, behavior data, etc. relevant to individuals, clients, crowds, etc. acquired in the embodiments of the present disclosure have been authorized.

It should be noted that, the user terminal and the AP cluster are connected through a wireless network, the user terminal can utilize the wireless local area network of the AP cluster to perform data transmission and communication when accessing the AP cluster, and the AP cluster includes: a plurality of APs for providing data transmission services for a user terminal.

S304, configuring a plurality of APs in the AP cluster to obtain an uplink AP for providing uplink data transmission service for the user terminal and a downlink AP for providing downlink data transmission service for the user terminal.

It should be noted that, in the embodiment of the present disclosure, the AP cluster obtained by configuring the APs in the AP cluster in advance includes an uplink AP that provides an uplink data transmission service for the user terminal and a downlink AP that provides a downlink data transmission service for the user terminal. Generally, an AP providing an uplink data transmission service for a user terminal needs to be used for transmitting a user data packet to a network, and needs to optimize its transmission rate, signal quality and stability, appropriately increase an uplink bandwidth, and reduce delay as much as possible. The AP providing the downlink data transmission service for the ue needs to be configured to receive the data packet sent by the server, and needs to optimize its transmission rate, signal quality and stability, increase the downlink bandwidth appropriately, and reduce the delay as much as possible. The specific configuration may be implemented by different network management tools, software or instructions.

According to the method provided by the embodiment of the disclosure, the uplink AP for providing the uplink data transmission service for the user terminal and the downlink AP for providing the downlink data transmission service for the user terminal can be configured in the AP cluster, so that stable network data transmission is realized.

It should be noted that a frame format period refers to a sequence of a set of subcarriers and time slots, through which data is transmitted. In this configuration, the configuration of the frame format period of each AP in the AP cluster includes a full uplink time slot, a full downlink time slot, and a sub-band full duplex time slot. Wherein, the full uplink time slot only comprises uplink sub-carriers and is used for transmitting uplink data; the full downlink time slot only comprises downlink subcarriers and is used for transmitting downlink data; the sub-band full duplex time slot simultaneously comprises an uplink sub-carrier and a downlink sub-carrier, wherein the uplink sub-carrier is used for transmitting uplink data, and the downlink sub-carrier is used for transmitting downlink data.

For a single AP, the frame format period will be configured as three different types of time slots, and when the single AP is used as an uplink AP for providing uplink data transmission service by a user terminal, the subband full duplex time slot is only used for transmitting uplink data in the frame format period, and similarly, when the single AP is used as a downlink AP for providing uplink data transmission service by a user terminal, the subband full duplex time slot is only used for transmitting downlink data in the frame format period, and when one uplink AP and one downlink AP serve the same user terminal, the subband full duplex is realized.

It should be noted that, fig. 5 shows a schematic diagram of an AP frame format, and as shown in fig. 5, the frame format of the AP in the embodiment of the disclosure is configured as a full downlink timeslot 501, a sub-band full duplex timeslot 502, and a full uplink timeslot 503, where the full uplink timeslot 503 only includes an uplink subcarrier for transmitting uplink data; the full downlink timeslot 501 only includes downlink subcarriers for transmitting downlink data; the sub-band full duplex slot 502 contains both uplink sub-carriers for transmitting uplink data and downlink sub-carriers for transmitting downlink data.

The AP may operate normally using the entire carrier in both the full uplink time slot 503 and the full downlink time slot 501. When the AP is used as a downlink AP, as shown in fig. 6, the sub-band full duplex timeslot 502 performs data transmission only on the downlink sub-carrier; when the AP is an uplink AP, as shown in fig. 7, the sub-band full duplex slot 502 performs data transmission only on the uplink sub-carrier.

The uplink and downlink switching is performed according to the time division multiplexing principle. The channel resources can be fully utilized, the channel utilization rate is improved, and the mutual interference and collision between uplink and downlink communication can be avoided, so that the communication quality is ensured.

It should be noted that the second data type is a data type that the time delay of the downlink data to be transmitted on the user terminal is greater than a preset time delay threshold, the preset time delay threshold is a set time value, when the time delay of the downlink data to be transmitted is greater than the preset time delay threshold, the data type is considered to be the second data type, and the corresponding user terminal can be understood to be the time delay insensitive downlink terminal, specifically illustrated, the second data type can be asynchronous transmission data, streaming media data, and the like, wherein the data transmission of the type of the asynchronous transmission data does not need real-time response, such as e-mail, file downloading, and the like. The service types such as streaming media data and the like have low delay requirements, such as audio streaming media, video streaming media and the like.

And when the data type is the second data type, acquiring the distance between the user terminal and each AP in the AP cluster serving the user terminal, and taking at least one downlink AP meeting the first preset distance condition in the AP cluster as the AP for providing the data transmission service for the user terminal so as to transmit the data of the second data type on the user terminal.

The first preset distance condition is a distance condition set in advance, specifically, at least one AP closest to the first preset distance condition is taken as a main AP, and several other downstream APs closer to the first preset distance condition are combined to serve the user terminal.

In some embodiments of the present disclosure, when the delay insensitive downlink user terminal is closer to the uplink sub-band AP, the uplink sub-band AP may be accessed to obtain the uplink data transmission service under the condition of the downlink capacity permission.

In some embodiments of the present disclosure, fig. 11 shows a communication method of the present disclosure for a third data type, as shown in fig. 11, according to a data type of data to be transmitted on a user terminal, an AP providing a corresponding data transmission service for the user terminal is selected from an AP cluster of the user terminal, including the following steps:

s1102, obtaining the distance between the user terminal and each AP in the AP cluster.

And S1104, taking at least one uplink AP meeting the second preset distance condition in the AP cluster as an AP for providing data transmission service for the user terminal so as to transmit data of a third data type on the user terminal.

It should be noted that, the third data type is a data type that the time delay of the uplink data to be transmitted on the ue is greater than a preset time delay threshold, the preset time delay threshold is a set time value, when the time delay of the downlink data to be transmitted is greater than the preset time delay threshold, the data type is determined to be the third data type, and the corresponding ue may be understood that the ue is a time delay insensitive uplink terminal, specifically, the following examples are taken as reference:

such as home smart home: the home smart home devices generally need to report usage data, such as power usage, air quality, etc., to the cloud, and these data are third data, generally do not need to respond in real time, and are insensitive to time delay.

Network camera: and uploading the video stream to the cloud for processing by the network camera, wherein the video stream data is third data, and the user terminal belongs to a delay insensitive uplink terminal.

And when the data type is the third data type, acquiring the distance between the user terminal and each AP in the AP cluster serving the user terminal, and taking at least one uplink AP meeting the second preset distance condition in the AP cluster as the AP for providing the data transmission service for the user terminal so as to transmit the data of the third data type on the user terminal.

The second preset distance condition is a distance condition set in advance, which may be the same as the first preset distance value, and only means distinction here, specifically, at least one uplink AP closest may be taken as a main AP, and several other uplink APs closer may be combined to serve the ue.

In some embodiments of the present disclosure, when the delay insensitive uplink user terminal is closer to the downlink subband AP, the downlink subband AP may be accessed to obtain the downlink data transmission service under the condition of allowing uplink capacity.

In some embodiments of the present disclosure, fig. 12 shows a communication method of the present disclosure for a fourth data type, as shown in fig. 12, according to a data type of data to be transmitted on a user terminal, an AP providing a corresponding data transmission service for the user terminal is selected from an AP cluster of the user terminal, including the following steps:

s1202, obtaining the distance between the user terminal and each AP in the AP cluster.

And S1204, using at least one uplink AP and at least one downlink AP which meet a third preset distance condition in the AP cluster as an AP for providing data transmission service for the user terminal so as to transmit data of a fourth data type on the user terminal.

It should be noted that, the fourth data type is a data type in which the time delay of the uplink data and/or the downlink data to be transmitted on the ue is smaller than a preset time delay threshold, the preset time delay threshold is a set time value, when the time delay of the uplink data and/or the downlink data to be transmitted on the ue is smaller than the preset time delay threshold, the data type is determined to be the fourth data type, and the corresponding ue can be understood as a ue that is a time delay sensitive terminal, that is, a ue that is very sensitive to the network time delay and needs to respond in real time, for example: remote control robot: the remote control robot needs to correspond to the instruction of an operator in real time, so that the stability and the safety of remote control are ensured. This data type is a fourth data type and the corresponding user terminal is very sensitive to time-lapse responses. Video conference terminal: video conference terminals require 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 delay and asynchronization of video and audio. On-line game terminal: the online game terminal needs to respond to the operation instructions of the player in real time to ensure the fluency of the game. If the delay is too high, the game will not be played and the player's gaming experience will be severely impacted.

For delay sensitive terminal applications, i.e. fourth data type data to be transmitted, it is often necessary to respond to changes in the network in a minimum time. This type of terminal device requires the use of a full duplex sub-band transmission mode to ensure that bi-directional data transmission is completed within a certain time. And obtaining the distance between the user terminal and each AP in the AP cluster, and taking at least one uplink AP and at least one downlink AP which meet the third preset distance condition in the AP cluster as the AP for providing data transmission service for the user terminal so as to transmit the data of the fourth data type on the user terminal. By simultaneously having an uplink AP and a downlink AP to serve the same user terminal, self-contained full duplex is realized, so that time delay can be minimized, and optimal network performance is realized.

In some embodiments of the present disclosure, the APs in the AP cluster may be tightly deployed, so as to avoid the problem of coverage weakening after uplink and downlink separation of the full duplex timeslots of the sub-band. When the data type to be transmitted in the AP cluster does not have the fourth data type, that is, when there is no delay sensitive terminal in the AP cluster, the sub-band full duplex time slot of the AP may 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, namely when a delay sensitive terminal exists in the AP cluster, the AP frame format period is configured to be provided with a sub-band full duplex time slot, and the transmitting power of the AP is correspondingly improved. In the process, the uplink and downlink sub-band attribution of a single AP and the division ratio of uplink and downlink sub-bands in clusters can be adjusted according to the load condition of each AP, but the uplink sub-band AP and the downlink sub-band AP are necessarily simultaneously existing near the time delay sensitive terminal. If the APs in the connected area belong to the same direction sub-band, the sub-band width of the AP far away from the adjacent direction sub-band AP in the area can be correspondingly enlarged so as to improve the overall network capacity and performance.

Based on the same inventive concept, there is also provided in an embodiment of the present disclosure a communication apparatus based on a cellular-free network system, as described in the following embodiment.
