The embodiment of the present application provides a data uploading method based on an aggregate terminal.

Refer to FIG. 2 , which is a flow chart of a first embodiment of a data uploading method based on an aggregation terminal of the present application.

In this embodiment, the data uploading method based on the aggregation terminal includes the following steps.

Step S10: determining the first aggregation terminal based on the first terminal identifier of the first aggregation terminal A corresponding second aggregation terminal, wherein the second aggregation terminal is connected to the first aggregation terminal.

The terminal is easily affected by many factors, resulting in a low uplink rate. As shown in Figure 3, when the terminal is at the edge of the cell (i.e., a far-point user), the uplink transmission power of the terminal is limited and the uplink rate cannot be increased; when the terminal is near the midpoint of the cell (i.e., a near-midpoint user), the terminal antenna is limited and cannot meet the uplink demand; in addition, the terminal bandwidth (for RedCap terminals, only 20M bandwidth is supported) may also limit the terminal's uplink rate.

In this embodiment, in order to solve the problem of low data upload rate, a data upload method based on an aggregation terminal is provided. The application environment of the terminals at different locations in the community includes ToC (To Customer, consumer-oriented) scenarios (such as AR/VR device applications, drones and high-traffic uplink data services) and ToB (To Business, enterprise-oriented) scenarios (including Internet of Vehicles, industrial cameras and electronic fences, etc.). The business data is uploaded separately through multiple air interfaces corresponding to at least two aggregation terminals, that is, the business data is uploaded separately through a first air interface corresponding to the first aggregation terminal and a second air interface corresponding to the second aggregation terminal connected to the first aggregation terminal. Through uplink multi-path transmission, the uplink rate of the business data is increased, and the user experience is improved.

In one example, each aggregated main terminal is pre-associated with its corresponding aggregated relay terminal according to the terminal identifier and stored. When it is detected that the uplink rate of a terminal is limited, it is determined whether the terminal is an aggregated main terminal based on the operation contract parameters or user setting instructions. When the terminal is an aggregated main terminal, the terminal is obtained as the first aggregated terminal. The first terminal identifier of the first aggregated terminal is obtained, and the second aggregated terminal is determined among the aggregated relay terminals associated with the first terminal identifier and connected to the first aggregated terminal. Among them, the technical architecture of the present embodiment is shown in FIG4, and the aggregated main terminal can be connected to the aggregated relay terminal based on the existing WIFI, Bluetooth, wired and other transmission interfaces, such as the two connection modes shown in the figure.

Step S20: Based on preset air interface transmission configuration information, a first air interface corresponding to the first aggregation terminal and a second air interface corresponding to the second aggregation terminal, the service data corresponding to the first aggregation terminal is uploaded by splitting.

In this embodiment, the air interface is the interface between the terminal and the access network. Preset air interface transmission configuration information Including the packet configuration information corresponding to the service data, the channel correspondence, the transmission mode, the main transmission path and the diversion threshold. When the service data reaches the diversion threshold, the service data is packetized according to the packet configuration information, and according to the channel correspondence, the packetized service data packets are diverted and uploaded through the first air interface corresponding to the first aggregation terminal and the second air interface corresponding to the second aggregation terminal.

In this embodiment, a data upload method based on an aggregation terminal is provided. The method determines the second aggregation terminal corresponding to the first aggregation terminal based on the first terminal identifier of the first aggregation terminal; and the service data corresponding to the first aggregation terminal is uploaded in a shunt based on the preset air interface transmission configuration information, the first air interface corresponding to the first aggregation terminal, and the second air interface corresponding to the second aggregation terminal. In the above manner, the present application uploads the service data in a shunt through multiple air interfaces corresponding to at least two aggregation terminals, that is, uploads the service data separately through the first air interface corresponding to the first aggregation terminal and the second air interface corresponding to the second aggregation terminal connected to the first aggregation terminal, and improves the uplink rate of the service data and the user experience through uplink multi-path transmission.

The present application also provides a second embodiment of a data uploading method based on an aggregation terminal.

In this embodiment, the first terminal is an aggregated main terminal, and the second terminal is an aggregated relay terminal. Before step S10, it also includes: marking the terminal as the aggregated main terminal or the aggregated relay terminal based on a terminal setting instruction triggered by an operation contract parameter or a user operation.

In this embodiment, the aggregated main terminal can perform diversion and upload of service data through the corresponding aggregated relay terminal to improve the data upload efficiency. The aggregated main terminal Remote UE and the aggregated relay terminal Relay UE include definition methods. The first method is defined by the operator. When the terminal leaves the factory, the operator will define the terminal based on the operation contract parameters, that is, define the terminal as an aggregated main terminal or an aggregated relay terminal. The second method is based on user operation definition. In the UE setting interface, the user is provided with option configurations of the aggregated main terminal Remote UE and the aggregated relay terminal Relay UE. The user can configure the terminal as an aggregated main terminal and an aggregated relay terminal according to actual needs. Based on the terminal setting instruction triggered by the user configuration operation, the terminal is defined as an aggregated main terminal or an aggregated relay terminal.

It is understandable that the configuration relationship between the Remote UE and the Relay UE is pre-configured or statically configured, and the configuration ratio is generally 1:1, that is, one Remote UE corresponds to one Relay UE. In one embodiment, one Remote UE may also correspond to multiple Relay UEs.

The present application also provides a third embodiment of a data uploading method based on an aggregation terminal.

In this embodiment, the step S20 includes: obtaining the subpacketization configuration information corresponding to the service data in the air interface transmission configuration information, and subpacketizing the service data based on the subpacketization configuration information; and uploading the subpacketized service data based on the first air interface and the second air interface.

In this embodiment, the subpacketization configuration information of the service data can be defined in advance in the air interface transmission configuration information. The subpacketization configuration information includes the number of subpackets, the subpacketization numbering method, and the subpacketization data volume, etc. According to the subpacketization configuration information, the service data is divided according to the subpacketization data volume, that is, the service data is divided into multiple subpackets, and the data volume of each subpacket is the subpacketization data volume; or the service data is divided according to the number of subpackets, and the number of subpackets after division is equal to the number of subpackets. And the divided subpacket data are numbered according to the subpacketization numbering method, such as sequential numbering, 1, 2, 3..., or odd numbering, 1, 3, 5..., etc. Finally, each data packet after division is shunted and uploaded through the first air interface and the second air interface.

The present application also provides a fourth embodiment of a data uploading method based on an aggregation terminal.

In this embodiment, the service data after packetization is diverted and uploaded based on the first air interface and the second air interface, including: obtaining the first logical channel configuration information corresponding to the first aggregation terminal and the second logical channel configuration information corresponding to the second aggregation terminal in the air interface transmission configuration information; determining the first air interface and the first data packet transmitted corresponding to the first air interface based on the first logical channel configuration information, and determining the second air interface and the second data packet transmitted corresponding to the second air interface based on the second logical channel configuration information; based on the first air interface and the second air interface, the first data packet and the second data packet are diverted and uploaded respectively to complete the diversion upload of the service data after packetization.

In this embodiment, the corresponding logical channel configuration information is configured for each terminal in advance in the air interface transmission configuration information. The logical channel configuration information is used to indicate the air interface information of the channel for each terminal to transmit data. Then, when uploading the split stream, the first aggregation terminal is determined based on the first logical channel configuration information. The first air interface for transmitting data is determined as the second air interface for uploading data by the second aggregation terminal based on the second logical channel configuration information. Then, based on the subpacket configuration information, the subpacket to be transmitted corresponding to the first air interface is determined as the first data packet, and the subpacket to be transmitted corresponding to the second air interface is determined as the second data packet. Finally, the first data packet is transmitted through the first air interface, and the second data packet is transmitted through the second air interface.

In this embodiment, the uplink air interface resources of two UEs are used to provide uplink transmission, and the service data is uploaded through a direct path (i.e., the first air interface of the first aggregation terminal) and an indirect path (i.e., the second air interface of the second aggregation terminal), thereby improving the uplink rate and reducing the load of the first aggregation terminal.

The present application also provides a fifth embodiment of a data uploading method based on an aggregation terminal.

In this embodiment, based on the first air interface and the second air interface, the first data packet and the second data packet are respectively diverted and uploaded to complete the diverted upload of the service data after packetization, including: when there is data replication configuration information in the air interface transmission configuration information, based on the main channel and the auxiliary channel of the first air interface, the first data packet and the copy of the first data packet are respectively transmitted, and based on the main channel and the auxiliary channel of the second air interface, the second data packet and the copy of the second data packet are respectively transmitted.

In this embodiment, in order to prevent data from being lost during upload, the user can select an upload mode in the terminal. When the backup transmission mode triggered by the user operation is received, that is, when the data replication configuration information is detected in the air interface transmission configuration information, a copy of the first data packet and a copy of the second data packet are generated. The first data packet and its copy are transmitted through the primary channel and the secondary channel of the first air interface, respectively. And the second data packet and its copy are transmitted through the primary channel and the secondary channel of the second air interface, respectively.

It can be understood that the copy of the first data packet is completely identical to the data of the first data packet, and the copy of the second data packet is completely identical to the data of the second data packet.

In this embodiment, the data packet and its copy are transmitted through two channels of each terminal respectively, so as to complete the backup transmission of the business data and avoid the loss of data during the transmission process. Incomplete, improving the reliability of data transmission.

The present application also provides a sixth embodiment of a data uploading method based on an aggregation terminal.

In this embodiment, before step S10, it also includes: obtaining the transmission parameters corresponding to the transmission of the service data by the first aggregation terminal, and determining whether the service data meets the diversion upload conditions based on the transmission parameters and the diversion threshold in the air interface transmission configuration information; if the service data meets the diversion upload conditions, generating a diversion upload instruction to divert and upload the service data. If the service data does not meet the diversion upload conditions, obtaining the main path information in the air interface transmission configuration information; based on the main path information, determining the target aggregation terminal among the aggregation terminals corresponding to the service data, and transmitting the service data based on the air interface corresponding to the target aggregation terminal.

In this embodiment, when it is detected that the first aggregation terminal transmits the service data, a transmission parameter corresponding to the service data transmitted by the first aggregation terminal is obtained. The transmission parameter may be the total amount of service data or the transmission rate at which the first aggregation terminal transmits the service data. The total amount of data is compared with the data threshold in the diversion threshold, or the transmission rate is compared with the rate threshold in the diversion threshold. When the total amount of data is greater than the data threshold or the transmission rate is less than the rate threshold, it is determined that the service data meets the diversion upload condition, and a diversion transmission instruction can be generated to divert and upload the service data through the second aggregation terminal corresponding to the first aggregation terminal. When the total amount of data is not greater than the data threshold or the transmission rate is not less than the rate threshold, it is determined that the service data does not meet the diversion upload condition, and the service data is transmitted based on a pre-set main path. The main path may be the first air interface corresponding to the first aggregation terminal, or the second air interface corresponding to the second aggregation terminal. In one instance, the air interface corresponding to the aggregated main terminal can be set as the main path first, or the main path can be determined based on the transmission rates of the aggregated main terminal and the aggregated relay terminal, that is, the air interface with a large transmission rate can be set as the main path. The main path can also be determined based on the positions of the aggregated main terminal and the aggregated relay terminal, that is, the air interface located in the middle of the cell can be set as the main path.

The present application also provides a seventh embodiment of a data uploading method based on an aggregation terminal.

In this embodiment, the acquisition of the transmission corresponding to the service data transmitted by the first aggregation terminal Parameters, and before determining whether the service data meets the diversion upload conditions based on the transmission parameters and the diversion threshold in the air interface transmission configuration information, it also includes: configuring or updating the diversion threshold based on the setting instruction of the diversion threshold.

In this embodiment, the diversion threshold or main transmission path of the service data can be set in advance through the base station or the aggregation main terminal. Among them, the diversion threshold is the minimum value required for diversion, and the main transmission path is the transmission path when diversion is not required. Generally, the main path is set to transmit service data through the aggregation main terminal. When receiving a setting instruction triggered by a user operation, it can be detected whether there is a diversion threshold at present. If there is no diversion threshold, the diversion threshold is set according to the setting instruction; if there is a diversion threshold, it is determined whether the current diversion threshold is the same as the diversion threshold to be set in the setting instruction. If they are not the same, the diversion threshold is updated. If they are the same, a message is fed back that the diversion threshold does not need to be updated.

The present application also provides an eighth embodiment of a data uploading method based on an aggregation terminal.

In this embodiment, before step S10, the method further includes: acquiring at least one terminal connected to the first aggregate terminal as a candidate terminal; and determining the second aggregate terminal from among the candidate terminals based on the terminal position of each candidate terminal relative to the cell to which the first aggregate terminal belongs.

In this embodiment, the number of terminals connected to the first aggregate terminal is obtained. When the number of terminals is not unique, each terminal is obtained as a terminal to be selected. The terminal position of each terminal to be selected is also obtained, that is, the terminal position of each terminal to be selected relative to the cell. Since the upload rate of the terminal located at the edge of the cell is lower than that of the terminal located in the middle of the cell, the terminal to be selected located in the middle of the cell can be obtained as the second aggregate terminal.

In one embodiment, the second aggregated terminal may also be determined according to the number of antennas included in the terminal, that is, a terminal including a large number of antennas is obtained as the second aggregated terminal.

The present application also provides a ninth embodiment of a data uploading method based on an aggregation terminal.

In this embodiment, the determining, based on the first terminal identifier of the first aggregation terminal, the second aggregation terminal corresponding to the first aggregation terminal includes: obtaining, based on the first terminal identifier, the first aggregation terminal; when the number of aggregate relay terminals corresponding to the first aggregate terminal is not unique, obtaining the measured signal strength corresponding to each of the aggregate relay terminals; determining the terminal with the largest measured signal strength among the aggregate relay terminals as the second aggregate terminal.

In this embodiment, according to the first terminal identifier of the first aggregation terminal, the aggregation relay terminal associated with the first terminal identifier is obtained. When it is determined that the number of aggregation relay terminals corresponding to the first aggregation terminal is not unique, the measured signal strength corresponding to each aggregation relay terminal is obtained in the aggregation relay terminals pre-configured by the first aggregation master terminal. The aggregation relay terminal with the largest measured signal strength can be selected as the second aggregation terminal.

As shown in Figure 5, the transmission system includes the aggregated main terminal Remote UE, the aggregated relay terminal Relay UE and the base station NG-RAN.

First, the Indirect Path (i.e., the transmission of Relay UE) is determined and the air interface RRC (Radio Resource Control) is configured. For example, the Relay UE is configured according to the aggregation requirements reported by the Remote UE (such as the total amount of business data), the Indirect Path quality (such as the signal quality or upload rate of each Relay UE), and other information. The Remote UE is configured with the main path, diversion threshold, etc., and the logical channels between the Remote UE and the Relay UE, as well as the packetized data to be transmitted corresponding to the logical channels, are configured.

After completing the above configuration, upload the basic information to RAN for storage. The basic information includes the identification of Remote UE and Relay UE, context information (including packet configuration information, logical channel configuration information, diversion transmission mode, diversion threshold and main path information) and Relation (the correspondence between Remote UE and Relay UE, the correspondence between logical channels and packets to be transmitted, etc.).

Based on the above information, the Direct Uu interface (i.e. the air interface corresponding to the Remote UE) and the Indirect Uu interface (i.e. the air interface corresponding to the Relay UE) are called to divert and transmit the service data to be transmitted by the Remote UE.

The interaction process within the system is as follows.

1. Relay UE enters RRC (Radio Resource Control) connection In the connection state (i.e., the Relay UE initiates an RRC connection to the base station), the base station determines that the Relay UE supports the Relay capability (i.e., determines that the UE is a Relay UE based on the UE identifier), and the base station allocates an ID to it.

2. The Remote UE initiates an RRC connection to the base station, and the base station determines that it has the Aggregation capability (i.e. determines that the UE is a Remote UE based on the UE identifier) and reports the ID of the corresponding Relay UE.

3. After the base station authenticates the Relay UE reported by the Remote UE, if it is evaluated that the reported Relay UE meets the UE Aggregation triggering conditions (including whether the Remote UE is connected to the Relay UE and whether the Relay UE and the Remote UE are in the same base station), the base station performs air interface RRC configuration to the Relay UE and the Remote UE respectively, indicating the diversion threshold and main path of the PDCP (Packet Data Convergence Protocol) of the DRB (data radio bearer) that currently needs to be aggregated, the RLC (Radio Link Control Protocol RLC) configuration (i.e., subpacketization configuration), and the logical channel configuration.

4. The Remote UE performs air interface uplink traffic diversion according to the configuration of the base station, and transmits the air interface uplink traffic diversion through the Remote UE and Relay UE respectively.

As shown in FIG6 , the diversion upload process is described in combination with the above transmission system and scenario.

2. After the Remote UE initiates an RRC connection to the base station, the base station sends the terminal capability to the Remote UE. The capability query request UE CapabilityEnquiry performs capability query (ie, queries whether it is a Remote UE or a Relay UE), and the UE reports the UE capability (ie, reports whether it is a Remote UE or a Relay UE) through the terminal capability UE Capablity Information message.

10. The MAC at the base station requests scheduling according to the UE BSR.

11. The PDCP on the base station side collects data based on the two RLC information, aggregates and delivers the collected data, and completes the merging and transmission of the diverted data.

Through the above-mentioned manner, this embodiment solves the problem of limited transmission channel or limited transmission power, and improves the uplink rate of data. Therefore, in the TOC or TOB scenario, when the terminal is at the edge and midpoint of the cell or the RedCap terminal is in the case of limited uplink bandwidth resources, air interface data transmission is performed through the UE direct path and the indirect path after interconnection with other N UEs (N>=2), that is, uplink multi-path transmission is provided, which improves the uplink rate and meets the data uplink requirements of the application.
