Description

Data transmission method, related device, equipment and communication system

Technical Field

Embodiments of the present application relate to the field of communications, and in particular, to a data transmission method, a related device, an apparatus, and a communication system.

Background

In an industry application scenario facing To an enterprise client (To Business, 2B), different services have different requirements on a network, some services require low delay, some services require uplink large bandwidth, and some services require high reliability. Due to network construction, standard specification, chip cost constraint and other reasons, the uplink rate provided by a single user equipment in part of scenes cannot meet the service requirement. For example, the number of uplink and downlink subframes for a new air interface (NR) in the third generation partnership project (3rd generation artnership project,3GPP) protocol may be very flexibly configured, and some constraints and limitations may be introduced in the network planning and product implementation, for example, when NR is co-band with long term evolution (long term evolution, LTE) Time Division duplex (Time Division duplexing, TDD) or Time Division-synchronous code Division multiple access (Time Division-Synchronous Code Division Multiple Access, TD-SCDMA), the frame structure of NR is required to be consistent with LTE (or TD-SCDMA), resulting in insufficient uplink subframes. On the other hand, the transmitting power of the terminal is lower, so that the uplink rate which can be provided by the terminal is relatively insufficient compared with the downlink rate. Or in order to reduce the production cost, most industries have a need for low cost module chips. The low-cost chip module has weak communication capability, for example, is oriented to a medium-low end internet of things, only supports 20 megahertz (MHz) bandwidth, single-receive single-transmit (1transmit 1receive,1T1R) or single-receive double-transmit (1transmit 1receive,1T2R), and cannot meet the requirements of scene application such as reliability, bandwidth and the like.

Currently, for a service with high reliability requirement, multiple terminal devices at a transmitting end can simultaneously transmit the same path of data, and then the service is optimized and de-duplicated at a receiving end. The method aims at the scene that the same user has multiple services at the same time and the service quality (Quality of Service, qoS) requirements are inconsistent, and can also avoid the problems by using a plurality of terminal devices to independently bear different services respectively.

However, multiple terminal devices can simultaneously transmit the same path of data, which occupies multiple air interface resources, so that expensive air interface resources are required to be consumed to ensure extremely low service delay. Secondly, when the user uses a plurality of terminals to bear multi-path services respectively, the network side does not perceive that the terminals have cooperation requirements, and can not allocate optimal resources for the user with high QoS requirements. All of which reduce the quality and efficiency of data transmission.

Disclosure of Invention

The embodiment of the application provides a data transmission method, a related device, equipment and a communication system, which can consider the cooperation requirements of a plurality of user equipment and receive and transmit a plurality of data packets of target service through at least one user equipment and network equipment in a User Equipment Group (UEG), thereby improving the quality and efficiency of data transmission.

A first aspect of the embodiments of the present application provides a method for data transmission, which may be performed by a user equipment group (user equipment group, UEG) or may also be performed by a chip configured in the UEG, which is not limited by the present application. The method comprises the following steps: the UEG acquires service requirements of a target service, the UEG comprises a plurality of user equipment with a data transmission function, the plurality of user equipment are used for carrying out data transmission on the same service or a plurality of services, and the user equipment belonging to the same UEG have the same UEG identifier. Then, the ue g determines a data transmission manner according to the service requirement of the target service, and at least one user equipment in the ue g sends a plurality of data packets of the target service to the network equipment based on the data transmission manner, or receives a plurality of data packets of the target service from the network equipment, or sends a plurality of data packets of the target service to the network equipment, and receives a plurality of data packets of the target service from the network equipment.

In this embodiment, the data transmission manner can be determined according to the service requirement of the target service, the cooperation requirement of a plurality of user equipments is considered, and at least one user equipment in the user equipment group UEG receives and transmits a plurality of data packets of the target service with the network equipment based on the data transmission manner, thereby improving the quality and efficiency of data transmission.

In an alternative embodiment of the present application, the target service is a service, and the service requirement of the target service is a high reliability requirement. Based on the above, the first ue in the UEG sends the plurality of data packets of the target service to the network device, or receives the plurality of data packets of the target service from the network device, or sends the plurality of data packets of the target service to the network device, and receives the plurality of data packets of the target service from the network device, where the ue transmitting the plurality of data packets of the target service is defined as the ue to be scheduled, and the ue to be scheduled is set in the state to be scheduled. Further, when the user equipment switching condition is met, the ue g determines a second user equipment in the user equipment to be scheduled, and therefore the second user equipment in the ue g sends a plurality of data packets of the target service to the network equipment, or receives a plurality of data packets of the target service from the network equipment, or sends a plurality of data packets of the target service to the network equipment, and receives a plurality of data packets of the target service from the network equipment.

In this embodiment, since only one UE performs data transmission with the network device at the same time, other UEs are in a state to be scheduled, that is, UEs in a state to be scheduled consume only very few network resources, thereby enabling saving of network resources for data transmission. Secondly, under the condition that the switching condition of the user equipment is met, data transmission between one UE and the network equipment can be determined from other UEs in a state to be scheduled, and when the UE G selects the switched UE, the switching preparation time can be saved, namely, the switching efficiency of the UE is improved, so that the possibility of data transmission delay can be reduced, and the reliability and the efficiency of data transmission are further improved.

In an optional embodiment of the application, the ue handover condition is that the quality of service of the first ue does not meet a quality of service condition, where the quality of service condition includes at least one of a channel quality condition, a channel resource condition, a signal strength condition, a cell status condition, and a throughput rate condition.

In this embodiment, the channel quality of the data transmission with the network device is poor, or the channel resource of the cell in which the ue g is located is insufficient, or the signal strength of the cell in which the ue g is located is small, or the cell state of the cell in which the ue g is located does not satisfy the state condition, or the throughput rate of the cell in which the ue g is located is small. The reliability and efficiency of data transmission may be affected, so that the current cell cannot provide the best service experience, so that in order to ensure that the data transmission can be stably transmitted, the UE needs to be switched in the UEG, thereby ensuring that more reliable data transmission can be performed, and further improving the reliability of the data transmission and the service quality of the target service.

In an alternative embodiment of the application, the quality of service condition comprises a channel quality condition. Based on the above, the ue g can also measure the channel quality of the ue to be scheduled to obtain the channel quality to be selected, where the channel quality to be selected corresponds to the ue to be scheduled one by one. Further, when the service quality of the first user equipment does not meet the channel quality condition, the ue g determines a target channel quality from the channel qualities to be selected, and the ue g determines the user equipment to be scheduled corresponding to the target channel quality as the second user equipment.

In this embodiment, in the case that the channel quality of data transmission with the network device is poor, the reliability and efficiency of the data transmission are affected, so in order to ensure that the data transmission can be stably transmitted, it is necessary to measure the channel quality of all UEs to be scheduled in the UE g, and select the UE to be scheduled with better channel quality as the switched UE (i.e., the second user equipment), and perform the data transmission between the UE and the network device, so that the reliability of the data transmission can be ensured.

In an alternative embodiment of the present application, the target service is a service, and the service requirement of the target service is a capacity requirement. Based on this, each ue in the UEG sends a plurality of data packets of the target service to the network device, or receives a plurality of data packets of the target service from the network device, or sends a plurality of data packets of the target service to the network device, and receives a plurality of data packets of the target service from the network device, where each ue carries at least one data packet.

In this embodiment, when the network resources for data transmission are not limited, since multiple data packets of the same service are commonly carried by each UE of the UEG, the maximum limitation of bandwidth can be increased, and further, the efficiency of data transmission can be improved.

In an alternative embodiment of the present application, the target service includes a plurality of different types of services, and the service requirement of the target service is a service isolation requirement. Based on this, each user equipment in the UEG transmits a plurality of data packets of the target service to the network equipment, or receives a plurality of data packets of the target service from the network equipment, or transmits a plurality of data packets of the target service to the network equipment, and receives a plurality of data packets of the target service from the network equipment. At this time, a plurality of data packets of the same type of service are transmitted by at least one user equipment, and the user equipment transmits only a plurality of data packets of one type of service.

In this embodiment, each UE in the same UEG may carry multiple data packets of different services, and the use of the data packets of different services of different UEs may avoid mutual influence between the data packets of different services, and avoid problems such as large delay or large jitter, thereby improving reliability of data transmission and improving service quality of the target service.

In an alternative embodiment of the present application, the UE g obtains the service requirement of the target service by different manners, including but not limited to, determining the service requirement of the target service by the UE g itself, or determining the service requirement of the target service by the network device, and sending the service requirement of the target service to each UE in the UE g, so that the UE g can receive the service requirement of the target service sent by the network device.

In this embodiment, the UEG obtains the service requirements of the target service in different manners, so that the UEG can adapt to different target services and actual application scenarios, thereby improving flexibility and feasibility of the scheme.

In an alternative embodiment of the application, the UEG is obtained by mapping user equipments into one service subscriber, and each user equipment is allocated a different network resource for data transmission.

In this embodiment, multiple UEs in the same UEG can serve the same user, and since different user equipments are respectively allocated with different network resources for data transmission, UEs in the UEG can consider the cooperative requirements of multiple user equipments to ensure the quality and efficiency of data transmission, but each UE will not affect the network resources of each other, i.e. no collision of network resources will occur, thereby ensuring the reliability of data transmission.

In an alternative embodiment of the present application, the UEG sends a data transmission manner to the network device, so that the network device configures data transmission resources according to the data transmission manner.

In this embodiment, the ue g sends a data transmission manner to the network device, and the network device can configure data transmission resources according to the data transmission manner, so as to ensure that the network device can send data packets to the ue g smoothly, or receive data sent by the ue g, or receive multiple data packets of a target service, and send multiple data packets of the target service, so as to improve feasibility of the scheme.

The second aspect of the embodiments of the present application provides another method for data transmission, which may be performed by a network device, or may also be performed by a chip configured in the network device, which is not limited by the present application. The method comprises the following steps: the network equipment acquires multiple User Equipment Group (UEG) identifiers, wherein the UEG comprises multiple user equipment with a data transmission function, the multiple user equipment is used for carrying out data transmission for the same service or multiple services, the user equipment belonging to the same UEG has the same UEG identifier, then a target UEG is determined according to the multiple User Equipment Group (UEG) identifiers, the target UEG is the UEG which serves the target service, and further multiple data packets of the target service sent by at least one user equipment in the target UEG are received, or multiple data packets of the target service are sent to at least one user equipment in the target UEG, or multiple data packets of the target service sent by at least one user equipment in the target UEG are received, and multiple data packets of the target service are sent to at least one user equipment in the target UEG.

In this embodiment, it is possible to determine, according to the ue group identifiers, which user group each user equipment belongs to, and determine the target ue g to which the target service needs to be performed, and receive or transmit a plurality of data packets of the target service between at least one ue in the ue group ue g and the network device based on the data transmission manner, and because the data transmission manner determined by the service requirement of the target service considers the cooperation requirements of the plurality of ues, it is possible to improve the quality and efficiency of data transmission.

And secondly, the network equipment can configure data transmission resources according to a data transmission mode so as to ensure that the network equipment can smoothly send data packets to the UEG, or receive data sent by the UEG, or receive a plurality of data packets of a target service and send a plurality of data packets of the target service, thereby improving the feasibility of the scheme.

Further, when the user equipment switching condition is met, the ue g determines the second user equipment in the user equipment to be scheduled, so that the network equipment receives a plurality of data packets of the target service sent by the second user equipment in the target ue g, or sends a plurality of data packets of the target service to the second user equipment in the target ue g, or receives a plurality of data packets of the target service sent by the second user equipment in the target ue g, and sends a plurality of data packets of the target service to the second user equipment in the target ue g.

In this embodiment, since the network device performs data transmission with only one UE in the UEG at the same time, the other UEs are in a state to be scheduled, that is, the UEs in the state to be scheduled consume only very few network resources, thereby being able to save network resources for data transmission. Secondly, under the condition that the switching condition of the user equipment is met, data transmission between one UE and the network equipment is determined from other UEs in a state to be scheduled, and when the UE G selects the switched UE, the switching preparation time can be saved, namely, the switching efficiency of the UE is improved, so that the possibility of data transmission delay can be reduced, and the reliability and the efficiency of data transmission are further improved.

Detailed Description

In order to make the above objects, technical solutions and advantages of the present application more comprehensible, a detailed description is provided below. The detailed description sets forth various embodiments of the devices and/or processes via the use of block diagrams, flowcharts, and/or examples. Because such block diagrams, flowcharts, and/or examples contain one or more functions and/or operations, it will be appreciated by those skilled in the art that each function and/or operation within such block diagrams, flowcharts, or examples can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or any combination thereof. The terms "first," "second," "third," "fourth" and the like in the description and in the claims and drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

In the industry application scenario of 2B, different services have different demands on the network, some services require low delay, some services require uplink large bandwidth, and some services require high reliability. Due to network construction, standard specification, chip cost constraint and other reasons, the uplink rate provided by a single user equipment in part of scenes cannot meet the service requirement. For example, the uplink and downlink subframes of NR in 3GPP protocols can be very flexibly configured, and some constraints and limitations are introduced in the process of network planning and product implementation, for example, when NR is co-band with LTE TDD or D-SCDMA, the frame structure of NR is required to be consistent with LTE (or TD-SCDMA), resulting in insufficient uplink subframes. On the other hand, the transmitting power of the terminal equipment is lower, so that the uplink rate which can be provided by the terminal equipment is relatively insufficient compared with the downlink rate. Or in order to reduce the production cost, most industries have a need for low cost module chips. The low-cost chip module has weak communication capability, for example, is oriented to a medium-low end internet of things, only supports 20MHz bandwidth, 1T1R or 1T2R, and cannot meet the scene application requirements of reliability, bandwidth and the like.

Specifically, in the industry application scenario of 2B, there may also be a scenario where multiple service data flows are mixed. In order to facilitate understanding, in the description of a remote control service of a gantry crane in a port scene, in the test point and deployment of a port scene 5G, the most critical service is the remote control service of the gantry crane in port equipment, and after an operator in a port central control room (remote control center) obtains a scheduling task issued by a wharf operation system, the operator remotely controls the moving operation of the gantry crane and a gripper thereof in real time through the communication of a programmable logic controller (Programmable Logic Controller, a PLC) -PLC of an operating lever according to high-definition video and audio data returned in real time on the gantry crane in a storage yard, so that the efficient and orderly stacking and transferring of containers are realized. After the gantry cranes realize remote control, one operator can control a plurality of gantry cranes, so that the idle time of the operator is reduced, the operation efficiency is improved, and the safety risk can be reduced. When the wireless network is required to be applied to the port scene gantry crane remote control service, the wireless network is required to ensure sufficient continuous coverage effect, meet requirements of bandwidth, time delay, packet reliability and the like of the PLC control service and the monitoring video backhaul service, and improve the efficiency of container operation on the premise of ensuring safe production.

From the foregoing examples and descriptions, it is apparent that when the wireless network is applied to various scenarios in the 2B field, at least the following three challenges need to be considered:

challenge one: the reliability requirement of the control service is high, and the reliability requirement is difficult to guarantee when the mobile network performs single connection.

Challenge two: the video service requires a larger bandwidth, and if a low-cost industrial module is used, the rate requirement of the video service is difficult to achieve.

Challenge three: for control and video stream coexistence scenarios, when a single customer premise equipment (customer premise equipment, CPE) simultaneously carries video and PLC control data streams, even if two paths of services respectively use different dedicated bearers, the video service will impact the PLC control service, resulting in large PLC delay jitter.

Based on this, for the first challenge, currently, for the service with high reliability requirement, multiple terminal devices at the transmitting end can simultaneously transmit the same path of data, and then, the receiving end prefers and de-retransmits the same path of data. For the second challenge, a high-specification chip module supporting a large bandwidth can be adopted currently, so that a high speed is obtained, and the speed requirement of video services is met. Secondly, for the challenge three, for the scene that the same user has multiple services at the same time and the service quality QoS requirements of the same user are inconsistent, the problem can be avoided by using a plurality of terminal devices to independently bear different services respectively.

However, multiple terminal devices can simultaneously transmit the same path of data, which occupies multiple air interface resources, so that expensive air interface resources are required to be consumed to ensure extremely low service delay. And the cost is higher because the low-capacity chip market of mass production is larger and the cost is far lower than that of a chip module with higher positioning. Secondly, when the user uses a plurality of terminals to bear multi-path services respectively, the network side does not perceive that the terminals have cooperation requirements, and can not allocate optimal resources for the user with high QoS requirements. All of which reduce the quality and efficiency of data transmission.

In order to solve the above problems, an embodiment of the present application provides a data transmission method for improving the quality and efficiency of data transmission. First, some terms or concepts related to the embodiments of the present application will be explained. The embodiment of the application introduces a new concept of a user equipment group (user equipment group, UEG). UEG is a special user type that refers to mapping two or more user equipments to one logical user. In a wireless network, a subscriber identity module (subscriber identity module, SIM) corresponds to a logical user equipment and a UEG contains a plurality of user equipments. From the physical aspect, the UEG may correspond to one terminal device (such as a dual-card handset), or may correspond to a plurality of independent terminal devices, or may include terminal devices in the above two aspects at the same time, which is not limited herein. For ease of understanding, referring to fig. 1, fig. 1 is a schematic diagram of an embodiment of a ue group according to the present application, as shown in fig. 1, since one UEG includes a plurality of ues and one SIM corresponds to one logical ue, from a physical aspect, fig. 1 (a) illustrates that one UEG may correspond to a plurality of terminal devices and each terminal device includes one logical ue (i.e., SIM), and fig. 1 (B) illustrates that one UEG corresponds to only one terminal device and the terminal device includes a plurality of logical ues (i.e., SIMs).

It should be understood that the data transmission method provided by the embodiment of the present application may be applied to various communication systems, for example: long term evolution (long term evolution, LTE) system, LTE frequency division duplex (frequency division duplex, FDD) system, LTE time division duplex (time division duplex, TDD), universal mobile telecommunications system (universal mobile telecommunication system, UMTS). With the continuous development of communication systems, the technical solution of the present application is applied to a 5G system or a New Radio (NR), and may also be applied to future networks, such as a 6G system, even future systems, etc., which is not limited herein.

It should be understood that the network device in the communication system may be any device having a wireless transceiver function or a chip that may be disposed on the device, where the network device includes, but is not limited to: an evolved Node B (eNB), a radio network controller (Radio Network Controller, RNC), a Node B (Node B, NB), a base station controller (Base Station Controller, BSC), a base transceiver station (Base Transceiver Station, BTS), a Home base station (e.g., home evolved NodeB, or Home Node B, HNB), a Base Band Unit (BBU), an Access Point (AP) in a wireless fidelity (WIRELESS FIDELITY, WIFI) system, a wireless relay Node, a wireless backhaul Node, a transmission Point (transmission Point, TP), or a Transmission Reception Point (TRP), etc., may also be a device used in a 5G, 6G or even future system, such as an NR, a gNB in a system, or a transmission Point (TRP or TP), one or a set of antenna panels (including multiple antenna panels) of a base station in a 5G system, or may also be a network Node constituting a gNB or transmission Point, such as a BBU, or a distributed Unit (BBU), or a pico Unit (tri), or a pico Unit (co), a femto Unit (4G, or a femto Unit), a femto Unit (4G, a femto Unit (4G), a femto Unit, a driving scenario (4G, a femto Unit, a 4G or a driving scenario, a 4G system, or the like.

In the embodiment disclosed in the present application, the means for implementing the function of the network device may be the network device, or may be a means capable of supporting the network device to implement the function, for example, a chip system, and the means may be installed in the network device.

It should also be appreciated that the user devices in the communication system may be mobile phones (mobile phones), tablet computers (Pad), computers with wireless transceiving functionality, virtual Reality (VR) terminal devices, augmented Reality (Augmented Reality, AR) terminal devices, wireless terminals in industrial control (industrial control), wireless terminals in unmanned (SELF DRIVING), wireless terminals in telemedicine (remote media), wireless terminals in smart grid (SMART GRID), wireless terminals in transportation security (transportation safety), wireless terminals in smart city (SMART CITY), wireless terminals in smart home (smart home), etc.

Further, in the current communication system, users are independent and not associated, so that the network device and the core network perform authentication, access control, radio resource scheduling, qoS guarantee and other management and operation for a single user, and each user does not need to cooperate. Based on the introduction of the UEG according to the embodiment of the present application, referring to fig. 2, fig. 2 is a schematic diagram of an embodiment of a system architecture according to the embodiment of the present application, where the system includes the UEG, a network device and a core network, as shown in fig. 2. Specifically, the UEG is a logical network element, and is composed of a plurality of UEs, where the plurality of UEs in the UEG and the network device may be directly or indirectly connected through a wired or wireless communication manner, and the present application is not limited herein. The network device is connected with the core network according to the standard interface, a plurality of data packets of the target service are uniformly connected to an external application server through the core network, and the external application server provides the required target service for the UE in the UEG based on the plurality of data packets of the target service. Therefore, the network device and the core network perform joint management for the UEG, and improve the performance of the user device in the network through reasonable scheduling configuration of resources, and how to perform data transmission in the system shown in fig. 2 is described in detail below.

Firstly, each UE in the UE g needs to add a UE g collaborative management function, so that each UE can determine a data transmission mode according to a service requirement of a target service, and at this time, the UE g sends a service data packet to the network device based on the determined data transmission mode and/or receives the service data packet sent by the network device. The service requirements in the embodiments of the present application include, but are not limited to, high reliability requirements, capacity requirements, service isolation requirements, and the like. For example, if the service requirement of the target service is a capacity requirement (such as video transmission), a data transmission mode corresponding to the capacity enhancement scene is required, and if the service requirement is a high reliability requirement (such as control service), a data transmission mode corresponding to the reliability enhancement scene is required, which is not limited herein.

Secondly, the network equipment is used as a radio resource management center, and needs to perceive that a plurality of UEs in the same UEG serve the same user, and then allocate the most reasonable resources for the UEs in the UEG according to the comprehensive quality condition of each data transmission link and the service requirement of the target service, so as to meet the QoS requirement of the UEG user. The network equipment allocates network resources for data transmission to each UE in the UEG respectively, and maps a plurality of member users of the network resources for data transmission to one user at the same time, so that the core network still manages the UEG according to one user, and the user equipment realizing a plurality of data transmission capacities serves one service user. Mapping a plurality of users of network resources for data transmission to one user means that the network device can allocate independent radio resources to the user devices, but the core network only needs to allocate a shared resource such as session resources, internet protocol addresses (internet protocol address, IP ADDRESS) to the user devices, so that the core network only counts the total flow of data transmission and the cost generated in practical application. Based on this, the network device can complete data transmission of session resources, IP addresses, and the like with the UEG. It is also planned and configured in advance that the UEs belong to the same UEG. Further, the network device can send the data packet of the service to the UEG and/or receive the data packet of the service sent by the UEG, and can also map the network resource users corresponding to each user equipment member in the UEG with the logic users of the core network, and then perform reasonable residence management, collaborative scheduling and resource allocation for the network resource users corresponding to each UE in the UEG according to the service requirements by means of resource management or scheduling pertinence, so that the UEG can meet the QoS required by the service.

And thirdly, the core network can carry out user authentication management, qoS rule formulation and policy issuing by taking the UEG as a unit. Specifically, the core network completes signing and account opening of the UEG user, authenticates and identifies the UEG user from the network attached storage (network attached storage, NAS) flow, allocates control plane and user plane resources of the core network to the UEG user according to the authentication and identification, carries out QoS negotiation with the UEG, establishes and manages session according to the granularity of the UEG user, and ensures QoS achievement of the UEG user. The core network is used as a switching center with the external application server, and the core network can distribute or terminate a plurality of data packets of the target service according to the service requirement of the target service, that is to say, the core network is used as a switching center on a channel path of the UEG and the application server, and the switching center needs to identify to which corresponding external application server the plurality of data packets of the target service should be sent.

Based on this, the scheme provided by the embodiment of the present application will be described from the aspect of the method, and since different data transmission manners will be provided based on different service requirements, the following description will describe the situations that the service requirements of the target service are respectively a high reliability requirement, a capacity requirement, and a service isolation requirement, it will be understood that, in practical application, the service requirement of the target service may also include a low latency requirement, and the service requirement of the target service may also include multiple service requirements, for example, the service requirement of the target service includes the capacity requirement and the service isolation requirement, or the service requirement of the target service includes the low latency requirement and the service isolation requirement, and therefore, the following description of the single service requirement should not be construed as limiting the present application.

1. High reliability requirements

Referring to fig. 3, fig. 3 is an interactive flow chart of a method for data transmission in an embodiment of the application, and as shown in fig. 3, the method for data transmission specifically includes the following steps.

S101, the network equipment acquires a plurality of User Equipment Group (UEG) identifiers.

In this embodiment, the network device obtains multiple UEG identifiers. As can be seen from the foregoing description, the UEG includes a plurality of user equipments having a data transmission function, and the plurality of user equipments can simultaneously perform data transmission for data packets of a same service, or the plurality of user equipments respectively perform data transmission for data packets of a plurality of services, where user equipments belonging to a same UEG have a same UEG identifier.

Specifically, the network device may obtain multiple UEG identifiers in different manners, e.g., the network device configures multiple UEG identifiers, or each ue reports a UEG identifier, so that the network device receives multiple UEG identifiers.

In particular, the UEG is obtained by mapping user equipments into one service user, and each user equipment is allocated different network resources for data transmission, respectively. The mapping of the ue into a service user means that the network device can allocate independent radio resources for the ue, but the core network only needs to allocate a shared resource such as session resource, IP address, etc. for the ue, so the core network only counts the total flow of data transmission and the cost generated in practical application. Based on this, the network device can complete data transmission of session resources, IP addresses, and the like with the UEG. It is also planned and configured in advance that the UEs belong to the same UEG. Further, the network device can send the data packet of the service to the UEG and/or receive the data packet of the service sent by the UEG, and can also map the network resource users corresponding to each user equipment member in the UEG with the logic users of the core network, and then perform reasonable residence management, collaborative scheduling and resource allocation for the network resource users corresponding to each UE in the UEG according to the service requirements by means of resource management or scheduling pertinence, so that the UEG can meet the QoS required by the service.

S102, the network equipment determines a target UEG according to the UEG identifications of the plurality of user equipment groups.

In this embodiment, the network device determines a target UEG according to the multiple UEG identifiers acquired in step S101, where the target UEG is a UEG serving the target service.

For example, if the network device can obtain the UEG identifiers corresponding to the plurality of user devices through the foregoing steps, and the UEG identifier corresponding to the user device a is "1", the UEG identifier corresponding to the user device B is "2", the UEG identifier corresponding to the user device C is "3", the UEG identifier corresponding to the user device D is "2", the UEG identifier corresponding to the user device E is "1", the UEG identifier corresponding to the user device F is "1", and the UEG identifier corresponding to the user device G is "3". Firstly, since ue a, ue E and ue F have the same identifier, it can be determined that ue a, ue E and ue F belong to the same ue G, and similarly, ue B and ue D belong to the same ue G, and ue C and ue G belong to the same ue G. Further, if the network device receives the service requirement about the target service sent by the user device a, it may determine that the ue g to which the user device a belongs is the target ue g (i.e. the ue g including the user device a, the user device E and the user device F). Similarly, if the network device receives the service requirement about the target service sent by the ue G, it can determine that the ue G to which the ue G belongs is the target ue G (i.e. the ue G including the ue C and the ue G). It should be understood that the foregoing examples are only for understanding the present solution, and the determination of the target UEG needs to be flexibly determined according to multiple UEG identities and the actual situation of the target service, and thus should not be construed as limiting the present application.

S103, the target UEG acquires the service requirement of the target service.

In this embodiment, the target UEG obtains the service requirement of the target service, and the service requirement of the target service is a high reliability requirement. As can be seen from the foregoing description, the target UEG includes a plurality of user equipments having a data transmission function, and the target UEG can perform data transmission for the target service, where the user equipments included in the target UEG have the same UEG identifier. It can be understood that, based on different service requirements and application scenarios, the target service may be a single service or multiple services, and since the service requirements of the target service described in this embodiment are high reliability requirements, the target services with high reliability requirements are all single services, for example, handling services and the like.

Specifically, the method for the target UEG to obtain the service requirement of the target service may include, but is not limited to: the target UEG determines a service requirement of the target service, or the target UEG receives the service requirement of the target service sent by the network device, which is not limited herein.

S104, the target UEG determines a data transmission mode according to the service requirement of the target service.

In this embodiment, the target UEG determines a data transmission manner according to a service requirement of the target service. Specifically, based on that each UE in the target UEG can be used as a bearer link and perform data transmission between the data of the target service and the network device, since a high reliability requirement needs to be guaranteed, only one UE connection performs data transmission at the same time in order to guarantee the reliability of the data transmission of the target service, which is a specific data transmission mode under the condition that the service requirement of the target service is the high reliability requirement.

S105, the target UEG sends a data transmission mode to the network equipment.

In this embodiment, the target UEG sends the data transmission manner determined in step S104 to the network device, so that the network device configures data transmission resources according to the data transmission manner.

S106, the network equipment configures data transmission resources according to the data transmission mode, wherein the data transmission resources are used for receiving a plurality of data packets of the target service and/or transmitting a plurality of data packets of the target service.

In this embodiment, the network device may configure data transmission resources according to a data transmission manner, so as to ensure that the network device may smoothly send data packets to the UEG, or receive data sent by the UEG, or receive multiple data packets of the target service, and send multiple data packets of the target service, so as to improve feasibility of the scheme.

S107, the first user equipment in the target UEG sends a plurality of data packets of the target service to the network equipment, and/or receives a plurality of data packets of the target service from the network equipment, wherein the user equipment which does not transmit the plurality of data packets of the target service is the user equipment to be scheduled, and the user to be scheduled is set to be in a state to be scheduled.

In this embodiment, as shown in step S104, the target service is a service, and the service requirement of the target service is a high reliability requirement, so that only one UE is connected to perform data transmission at the same time in order to ensure the reliability of data transmission of the target service. At this time, determining one UE as a first UE from all UEs in the target UEG, sending a plurality of data packets of the target service to the network device through the first UE, or receiving a plurality of data packets of the target service from the network device, or sending a plurality of data packets of the target service to the network device, and receiving a plurality of data packets of the target service from the network device. And secondly, at the moment, the user equipment transmitting the plurality of data packets of the target service is defined as the user equipment to be scheduled, namely, other UE which does not transmit data is in a state to be scheduled, and the UE in the state to be scheduled only consumes little network resources, so that the network resources for data transmission can be saved.

S108, when the user equipment switching condition is met, the target UEG determines a second user equipment in the user equipment to be scheduled.

In this embodiment, when the handover condition of the UE is met, the target UE g may determine that data transmission is performed between one UE and the network device from other UEs in a state to be scheduled, and when the UE g selects the UE to be handed over, the handover preparation time can be saved, that is, the handover efficiency of the UE is improved, so that the possibility of data transmission delay can be reduced.

Specifically, the user equipment switching condition is that the service quality of the first user equipment does not meet the service quality condition, wherein the service quality condition comprises at least one of a channel quality condition, a channel resource condition, a signal strength condition, a cell state condition and a throughput rate condition. It should be understood that the quality of service of the first ue is calculated by the network device according to the link combination condition of the first ue.

For example, when the quality of service condition includes a channel quality condition, that is, when the channel quality of data transmission with the network device is poor, reliability and efficiency of data transmission may be affected, and in order to ensure stable data transmission, handover of the UE needs to be performed in the UEG. Or when the service quality condition includes a channel resource condition, that is, the channel resource of the cell in which the UE g is located is smaller than the channel resource threshold, and the channel resource of the cell in which the UE g is located is insufficient, the current cell cannot provide the best service experience, so that the UE needs to be switched in the UE g. Or when the service quality condition includes at least one of a signal strength condition, or a cell state condition and a throughput rate condition, that is, the signal strength of the cell in which the UE g is located is smaller than a signal strength threshold, the cell state of the cell in which the UE g is located does not satisfy the state condition, and the throughput rate of the cell in which the UE g is located is smaller than the throughput rate threshold, where the foregoing conditions all indicate that the current cell cannot provide the best service experience, so that the UE needs to be switched in the UE g, thereby ensuring that more reliable data transmission can be performed, and further improving the reliability of data transmission and the service quality of the target service. It will be appreciated that the foregoing examples are merely for understanding the present solution, and that the quality of service condition may be a single condition or a combination of multiple conditions in different application scenarios and practical applications, and is not limited herein.

Further, for ease of understanding, taking the service quality condition including the channel quality condition as an example for explanation, in the case that the channel quality of data transmission with the network device is poor, the reliability and efficiency of the data transmission will be affected, and in order to ensure that the data transmission can be stably transmitted, it is necessary to measure the channel quality of all UEs in the UE to be scheduled, where the channel quality to be selected corresponds to the UE to be scheduled one by one. Based on the above, when the service quality of the first UE does not meet the channel quality condition, the target UE g determines the target channel quality from the channel quality to be selected, and the UE g determines the UE to be scheduled corresponding to the target channel quality as the second UE, i.e. selects the UE to be scheduled with better channel quality as the switched UE (i.e. the second UE), and performs data transmission between the UE and the network device, so that the reliability of data transmission can be ensured. It can be appreciated that the foregoing examples are only for understanding the present solution, and the decision mode of the second ue needs to be flexibly determined according to the specific ue handover conditions and the actual situation.

The second user equipment in the UEG sends and/or receives a plurality of data packets of the target service to and/or from the network equipment.

In this embodiment, in order to ensure the reliability of data transmission to the target service, only one UE connection performs data transmission at the same time. Based on the determination of the second user equipment in step S108, a plurality of data packets of the target service are sent to the network equipment through the second user equipment at this time, or a plurality of data packets of the target service are received from the network equipment through the second user equipment, or a plurality of data packets of the target service are sent to the network equipment through the second user equipment, and a plurality of data packets of the target service are received from the network equipment. Secondly, other UEs that do not perform data transmission are still in a state to be scheduled at this time, and when the switching condition of the UE introduced in step S108 is reached, or similar steps are repeatedly performed, which will not be described herein.

Further, for convenience in describing the embodiment shown in fig. 3, please refer to fig. 4, and fig. 4 is a schematic diagram of an application scenario of the method for data transmission in the embodiment of the present application, as shown in fig. 4, and fig. 4 (a) illustrates a scenario of data transmission between a first user equipment and a network equipment in a target UEG. In the case that the channel quality of data transmission with the network device is poor, or in the case that the current cell cannot provide the best service experience, and the like, in the case that the user equipment switching condition is satisfied, the reliability and efficiency of data transmission are affected, so that the second user equipment can be determined from other UEs in the target UEG in a state to be scheduled, and thus (B) in fig. 4 illustrates a scenario of data transmission between the determined second user equipment in the target UEG and the network device in the case that the user equipment switching condition is satisfied. Based on this, selecting the UE to be switched at the UEG can save the switching preparation time, that is, improve the efficiency of the UE to perform switching, so that the possibility of data transmission delay can be reduced, thereby further improving the reliability and efficiency of data transmission.

2. Capacity demand

Referring to fig. 5, fig. 5 is another interactive flow chart of a data transmission method in an embodiment of the application, and as shown in fig. 5, the data transmission method specifically includes the following steps.

S201, the network equipment acquires a plurality of User Equipment Group (UEG) identifiers.

It can be appreciated that the manner in which the network device obtains the plurality of ue group ue g identifiers is similar to step S101, and will not be described in detail herein.

S202, the network equipment determines a target UEG according to the UEG identifications of the plurality of user equipment groups.

In this embodiment, the network device determines a target UEG according to the multiple UEG identifiers acquired in step S201, where the target UEG is a UEG serving the target service.

It can be appreciated that the manner of determining the target UEG by the network device according to the plurality of ue group UEG identifiers is similar to step S102, and will not be described here again.

S203, the target UEG acquires the service requirement of the target service.

In this embodiment, the target UEG obtains the service requirement of the target service, and the service requirement of the target service is the capacity requirement. As can be seen from the foregoing description, the target UEG includes a plurality of user equipments having a data transmission function, and the target UEG can perform data transmission for the target service, where the user equipments included in the target UEG have the same UEG identifier. It can be understood that, based on different service requirements and application scenarios, the target service may be a single service or multiple services, and since the service requirement of the target service described in this embodiment is a capacity requirement, the target service having a capacity requirement is generally one service, for example, a video service.

It can be understood that the manner in which the network device obtains the service requirement of the target service is similar to step S103, and will not be described herein.

S204, the target UEG determines a data transmission mode according to the service requirement of the target service.

In this embodiment, the target UEG determines a data transmission manner according to a service requirement of the target service. Specifically, since the target service is a single service, a plurality of data packets of the target service are commonly carried by each UE in the UEG.

S205, the target UEG sends a data transmission mode to the network device.

In this embodiment, the target UEG sends the data transmission manner determined in step S204 to the network device, so that the network device configures data transmission resources according to the data transmission manner.

S206, the network equipment configures data transmission resources according to the data transmission mode, wherein the data transmission resources are used for receiving a plurality of data packets of the target service and/or transmitting a plurality of data packets of the target service.

S207, each ue in the target UEG sends a plurality of data packets of the target service to the network device, and/or receives a plurality of data packets of the target service from the network device, where each ue carries at least one data packet.

In this embodiment, since the target service is one service, the service requirement of the target service is a capacity requirement. Based on this, each user equipment in the target UEG sends a plurality of data packets of the target service to the network device, or each user equipment in the target UEG receives a plurality of data packets of the target service from the network device, or each user equipment in the target UEG sends a plurality of data packets of the target service to the network device, and receives a plurality of data packets of the target service from the network device. At this time, each ue carries at least one data packet of the target service.

For example, the plurality of data packets of the target service include data packet a, data packet B to data packet J, and the target UEG includes user equipment a, user equipment E, and user equipment F, where data transmission may be performed between the user equipment a and the network equipment for data packet a, data packet B, and data packet C, and data transmission may be performed between the user equipment B and the network equipment for data packet D, data packet E, and data packet F, and data transmission may be performed between the user equipment J and the network equipment for data packet G, data packet H, data packet I, and data packet J. It should be understood that the foregoing examples are only for understanding the present solution, and the decision manner of the second ue needs to be flexibly determined according to the specific ue handover conditions and the actual situation.

Further, in order to facilitate the description of the embodiment shown in fig. 5, referring to fig. 6, another application scenario of the method for data transmission in the embodiment of the present application shown in fig. 6 is that, as shown in fig. 6, the target service is based on a single service, so that multiple data packets of the target service can be commonly carried by each UE in the target UEG, that is, the target UEG shunts multiple data packets of the target service, the network device aggregates multiple data packets of the target service, and the maximum limitation of the bandwidth can be improved by stacking multiple UEs, thereby further improving the efficiency of data transmission.

3. Traffic isolation requirements

Referring to fig. 7, fig. 7 is another interactive flow chart of a data transmission method in an embodiment of the application, and as shown in fig. 7, the data transmission method specifically includes the following steps.

S301, the network equipment acquires a plurality of User Equipment Group (UEG) identifiers.

S302, the network equipment determines a target UEG according to the UEG identifications of the plurality of user equipment groups.

In this embodiment, the network device determines a target UEG according to the multiple UEG identifiers acquired in step S301, where the target UEG is a UEG serving the target service.

S303, the target UEG acquires the service requirement of the target service.

In this embodiment, the target UEG obtains the service requirement of the target service, and the service requirement of the target service is the service isolation requirement. As can be seen from the foregoing description, the target UEG includes a plurality of user equipments having a data transmission function, and the target UEG can perform data transmission for the target service, where the user equipments included in the target UEG have the same UEG identifier. It can be understood that, based on different service requirements and application scenarios, the target service may be a single service or multiple services, and since the service requirements of the target service described in this embodiment are service isolation requirements, the target service with a capacity requirement is typically multiple services, for example, including a manipulation service and a video service, or can also be other types of services, which are not limited herein.

S304, the target UEG determines a data transmission mode according to the service requirement of the target service.

In this embodiment, the target UEG determines a data transmission manner according to a service requirement of the target service. Specifically, since the target service is a plurality of services, a plurality of data packets of the same type of service are transmitted by at least one user equipment, and the user equipment transmits a plurality of data packets of only one type of service.

S305, the target UEG sends a data transmission mode to the network device.

In this embodiment, the target UEG sends the data transmission manner determined in step S304 to the network device, so that the network device configures data transmission resources according to the data transmission manner.

S306, the network equipment configures data transmission resources according to the data transmission mode, wherein the data transmission resources are used for receiving a plurality of data packets of the target service and/or transmitting a plurality of data packets of the target service.

S307, each ue in the target UEG sends a plurality of data packets of the target service to the network device, and/or receives a plurality of data packets of the target service from the network device, where a plurality of data packets of the same type of service are sent by at least one ue, and the ue sends a plurality of data packets of only one type of service.

In this embodiment, since the target service includes a plurality of different types of services, the service requirement of the target service is a service isolation requirement. Based on this, each user equipment in the UEG transmits a plurality of data packets of the target service to the network equipment, or receives a plurality of data packets of the target service from the network equipment, or transmits a plurality of data packets of the target service to the network equipment, and receives a plurality of data packets of the target service from the network equipment. At this time, a plurality of data packets of the same type of service are transmitted by at least one user equipment, and the user equipment transmits only a plurality of data packets of one type of service.

Further, in order to facilitate description of the embodiment shown in fig. 7, referring to fig. 8, another application scenario of the data transmission method in the embodiment of the present application shown in fig. 8 is shown in fig. 8, where each UE in the same UE g may carry multiple data packets of different services, and the use of the data packets of different services of different UEs may avoid mutual influence between the data packets of different services, so as to avoid problems such as large delay or large jitter, thereby improving reliability of data transmission and improving service quality of a target service.

It can be appreciated that the foregoing embodiment only describes a scenario in which the target service is a single service requirement, however, in practical applications, the target service may also include a plurality of different service requirements, and details of all possible scenarios are not described herein, and the scenario described in the foregoing embodiment should not be construed as limiting the present application.

In the above embodiment, by adding the UEG coordination module and the related signaling flow, the UEG, the base station, and the core network can all perceive that a plurality of UEs are serving the same user, so as to more pertinently perform radio resource allocation and QoS management, and effectively guarantee a service level agreement (SERVICE LEVEL AGREEMENT, SLA). The data transmission method introduced in the embodiment of the application can simultaneously utilize the processing and communication capabilities of a plurality of user equipment, and can also open the flow between a transmitting end and a receiving end, so that each network element of the UEG, the base station and the core network can sense the service requirement of the target service to perform reasonable access and resource management, thereby improving the reliability of the communication system.

It can be understood that the data transmission method described in the embodiment of the present application can be further extended to other mobile cellular networks or wireless networks carrying service data flows and wired networks (wired networks include but are not limited to WiFi, bluetooth, zigbee (Zigbee), ethernet, etc.), so as to comprehensively improve network performance and improve user experience.
