Detailed Description
Features and exemplary embodiments of various aspects of the present application will be described in detail below, and in order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings and the detailed embodiments. It should be understood that the specific embodiments described herein are merely configured to illustrate the application and are not configured to limit the application. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the application by showing examples of the application.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions; nor is it to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.
As communication technology evolves and user behavior habits change, mobile data services appear to grow in finger level. At present, the mobile network traffic generated in the indoor area has a very high proportion in the whole network, and with the increasing types and requirements of the vertical industry, the industry predicts that more than 85% of mobile services will occur in an indoor scene in the future, so that the indoor mobile network capability of an operator is crucial, and the mobile network traffic becomes one of the core competitiveness of the operator. Thus, to help operators quickly solve the indoor network coverage problem, digital indoor distribution technology has evolved. The principle of the digital indoor division is that signals of a mobile communication base station are uniformly distributed to each corner of an indoor through various indoor antennas, so that ideal signal coverage of an indoor area is ensured, and the digital indoor division belongs to an indoor distribution system.
In 5G (5 th -Generation, fifth Generation mobile phone mobile communication standard) network age, and subsequent 6G (6 th Generation, sixth Generation mobile phone mobile communication standard) deployment frequency is greatly different from that of the original network, and is different from that of 4G (4 th Generation, fourth Generation mobile phone mobile communication standard), 5G and 6G will be deployed on C-Band, millimeter wave and terahertz, for future 5G/6G indoor deployment, legacy 2G (2 nd -Generation, second Generation mobile phone mobile communication standard)/3G (3 rd The Generation, third Generation mobile phone mobile communication standard)/4G age of solution also faces significant challenges and innovative needs. The 5G/6G outdoor coverage room cannot meet the depth coverage requirement. In addition, the existing network passive device cannot be compatible with 5G/6G frequency, cannot support 5G/6G by direct joint path upgrading, and the new antenna feeder device has high loss in 5G/6G frequency band and partThe deployment cost is high. Meanwhile, the requirement of high-capacity service also tends to require that the multi-antenna technology is widely applied indoors, the requirement of service also drives the whole indoor network to be converted into digitalization, and the 5G/6G indoor system is comprehensively digitalized, has high capacity, is easy to deploy and can monitor evolution. The deployment scale of the 5G/6G era digital indoor network product is obviously improved.
When the terminal communicates with the digital indoor subsystem, a cell switching scene exists due to the mobility of the terminal. For example, in the context of AGVs (Automated Guided Vehicle, automated guided vehicles) cooperation, a handoff to an AGV cell is required when the AGV crosses the cell edge.
In the handover scenario, as shown in fig. 1, after the terminal device sends RRC Reconfiguration (Radio Resource Control Reconfiguration ) to the target network device, the UPF (User Plane Function ) starts to send data to the terminal device, and the process needs to go through UPF, BBU, HUB, PRRU and several devices of the UE, so that the user plane delay is larger. Therefore, during the handover process, a phenomenon of decline of the UPF data traffic is observed, which may be referred to as "dropping the channel" during the handover process.
In an industrial application scene, service data has high requirement on time delay, and if a large delay of data arrival occurs, a service layer is likely to report errors, so that production stagnation accidents are caused. For example, in the scenario of cooperation of an AGV (Automated Guided Vehicle, automatic guided vehicles), when the AGV crosses the cell edge, interruption of traffic control may occur due to a "run-out" phenomenon, thereby causing the AGV to lose control and requiring manual intervention for recovery.
Therefore, how to reduce the user plane handover delay is important.
In order to solve the technical problem, an embodiment of the present application provides a data transmission method under cell handover, where the method sends a first signaling to a target network device through a service network device, where the first signaling is used for a terminal device to switch from a cell covered by the service network device to a cell covered by the target network device; and simultaneously sending second signaling to the aggregation unit, wherein the second signaling is used for indicating to forward the user data from the service network equipment to the target network equipment. Therefore, the user data does not need to be forwarded through an Xn interface or an NG interface between the service network equipment and the target network equipment, but is transmitted through a convergence unit connected with the target baseband processing unit by the service baseband processing unit, so that the time delay of user plane data transmission is reduced.
The data transmission method under cell switching provided by the embodiment of the application is applied to a digital indoor subsystem, as shown in fig. 2, the digital indoor subsystem comprises: service network equipment, a convergence unit and target network equipment. Specifically, the service network device includes: the service baseband processing unit BBU1, the service remote unit (in this example, two service remote units are provided, PRRU1 and PRRU 2). The target network device includes: a target baseband processing unit BBU2 and a target remote unit (in this example, two target remote units are provided, PRRU3 and PRRU 4). In the digital room system, the BBU, HUB and PRRU can exist in a plurality at the same time, without limitation. The remote unit equipment is connected with the convergence unit equipment in a star cascade mode, the convergence unit equipment is connected with the baseband unit equipment in a star chain hybrid cascade mode, and the baseband unit equipment is connected with the core network. Wherein BBU1 and BBU2 communicate with HUB1 through optical fibers; HUB1 communicates with PRRU1, PRRU2, PRRU3, and PRRU4 via fiber optic or optoelectric composite cables.
The functions of each node in the digital indoor subsystem are as follows:
BBU1 (or BBU 2) is used to implement baseband processing flows. The modulation and demodulation functions of the 5G baseband signals are mainly realized, and the data receiving, transmitting and interfacing between the convergence units are supported.
HUB1 is used for communicating BBU1, BBU2 and PRRU1, PRRU2, PRRU3, PRRU4, carries out the combiner and the branching treatment of uplink and downlink data simultaneously.
The PRRU1 (or PRRU2, PRRU3, PRRU 4) is mainly configured to convert a digital signal into a radio wave and transmit the radio wave through an antenna, and can also receive a radio frequency signal from the antenna, perform corresponding signal processing, and send the radio frequency signal to a baseband unit device for processing through a convergence unit device.
The PRRU1, PRRU2, PRRU3 and PRRU4 realize communication with terminals in respective coverage areas by means of internal antennas, thereby realizing indoor coverage of the communication network.
The technical scheme provided by the embodiment of the application can be applied to various communication systems, such as an NR (new radio) communication system adopting a 5G communication technology, a 6G communication system, a future evolution system or a plurality of communication fusion systems and the like. The technical scheme provided by the embodiment of the application can be applied to various application scenes, such as indoor blind area scenes of newly built large buildings, parking lots, office buildings, hotels, apartments and the like, indoor places with high telephone traffic, such as stations, airports, markets, gyms, shopping centers and the like, and indoor scenes which are easy to switch frequently.

S103, the service network equipment sends the user data to the aggregation unit. Correspondingly, the aggregation unit receives the user data.
The user data is sent to the service network device by the UPF, and may include historical user data to be sent to the terminal device by the UPF before being sent to the service network device, and may also include real-time user data sent to the service network device by the UPF in real time. The user data may be transmitted in the form of data packets. Specifically, the user data may be service data of an application being used by the user, for example, video data of a video application or audio data of an audio spectrum application, etc.
And S104, the convergence unit responds to the second signaling and transmits user data to the target network equipment. Accordingly, the target network device receives user data from the aggregation unit.
Wherein the target network device may receive user data from the aggregation unit via a target remote unit in the target network device. The user data is sent by the aggregation unit through a digital exchange part in the aggregation unit, specifically, the digital exchange part is an FPGA (Field Programmable Gate Array ), the FPGA belongs to a semi-custom circuit in an application-specific integrated circuit, is a programmable logic array, and is matched with a traditional network card, for example: XL710, etc., uses and specialized custom program, realize the forwarding of user data, achieve the high performance of network forwarding, low delay goal. The special custom program used by the FPGA can be written with reference to the prior art, and will not be described in detail.
S105, the target network device sends the user data to the terminal device. Correspondingly, the terminal device receives the user data.
Wherein the target network device may send user data to the terminal device via the target remote unit. After receiving the user data, the terminal device can execute corresponding service according to the user data.

By way of example, the electronic device may include: ground robot and small aircraft.
In the embodiment of the application, the service network equipment forwards the second signaling to the convergence unit, and the convergence unit receives the second signaling from the service network equipment and the user data and sends the user data to the terminal equipment. In the cell switching scene, the user data is forwarded through the aggregation unit, and the service network equipment is not required to send the user data to the target network equipment through the Xn interface or the NG interface, so that the time delay of user plane data transmission is reduced. And, the capacity requirement for an Xn interface or an NG interface optical module is reduced.
