It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.
- base station capabilities have been enhanced, and native AI, edge computing and perception capabilities have been integrated to become more intelligent.
- Various information collected by the base station side needs to be distributed and transmitted between various functional network elements of the network for collaborative processing, or uploaded to the capability exposure node to provide to third-party APP (Application).
- the distribution of this data requires efficient, flexible, low-latency and secure channels or methods to carry it.
- the communication perception fusion scenario is still in the research and discussion stage, and the industry has not yet formed a unified view.
- the mainstream view is to maximize the reuse of 5GC functional network element interfaces, add communication perception functional units with control and computing capabilities, and provide capability exposure functions.
- the overall architecture of the communication perception fusion system is shown in Figure 1.
- the application layer function (Application Function, AF) network element is connected to the network exposure function (Network Exposure Function, NEF) network element through an interface
- the NEF network element is connected to the communication perception fusion function network element through the Nx interface (5G interface)
- the communication perception fusion function network element is connected to the mobility management function (Access and Mobility Management Function, AMF) network element through the Ny interface (5G interface)
- the communication perception fusion function network element is connected to the user plane function (The User Plane Function, UPF) network element through the N6 interface (5G interface)
- the AMF network element transmits perception control instructions to the base station (communicative integrated base station) through the N2 interface (5G interface)
- the base station reports perception data to the UPF network element through the N3 interface (5G interface).
- the newly added communication perception fusion function network element is responsible for the management and control of perception functions, the calculation and opening of perception information.
- management and control are mainly reflected in the management and control of the AMF network element perception function; computing is mainly reflected in the intelligent computing and processing of reported perception information; openness is reflected in the opening of perception information and data to the inside or outside of the network.
- the AMF is enhanced to have the communication perception function.
- a north-south interface is added to the communication perception fusion function network element, and the Nx interface (5G interface) of the NEF network element that opens external capabilities calls the Ny (5G interface) interface of the AMF, and reuses the N2 interface (5G interface).
- the Nx interface is used to realize the call of the perception capability of external applications or NFs inside the network and the reporting of perception results through NEF;
- the Ny interface is used to realize the control of the AMF perception function by the communication perception fusion network element;
- the N2 interface is used to realize the control of the base station perception function by AMF, and the AMF forwards the control instructions of the communication perception fusion network element function to the base station (communicative integrated base station).
- the N3 interface (5G interface) and the N6 interface (5G interface) are multiplexed, wherein the base station (synesthesia integrated base station) perception data is reported based on the N3 interface, and the perception data obtained by the base station (synesthesia integrated base station) is forwarded to the communication perception fusion functional network element based on the N6 interface.
- the base station management plane mainly controls and collects parameters for the base station through the network management system.
- Base stations can achieve collaboration by exchanging data through the Xn interface (5G interface) or X2 (5G interface).
- the base station and the core network element interact with each other through the N2 or S1 interface (5G interface). If the data is to be distributed to the intelligent processing node (or network element), it needs to be forwarded by the core network related network elements. The interaction process is too long, the logic is complex, and the current interface protocol needs to be modified.
- the current system and protocol do not support the interaction of application layer data such as perception data between the base station and the terminal, and edge computing is required to achieve the interaction of perception data with the terminal. Due to the huge number of base stations, it is difficult to deploy core network user plane network elements or edge computing units in each base station, making it difficult to achieve low-cost and low-latency perception data delivery with the current network deployment method.
- base station side video backhaul In order to realize the integration of communication perception and enhance the intelligence of base stations, it is necessary to realize efficient data distribution at the base station, such as base station side video backhaul, environmental monitoring data backhaul, perception data backhaul, air-space base station drone data backhaul, integrated perception network Two-way communication between Yuan and base station, base station data sending terminal, etc.
- the existing technical solution adds a communication perception fusion network element in the core network, and reuses the control plane and user plane of the existing cellular system to realize the control instructions and perception data transmission between the communication perception fusion network element and the base station.
- this solution can realize data distribution between the fusion perception network element and the base station, it is necessary to enhance the AMF (Access and Mobility Management Function) function and add a new interface, which increases the complexity of the interface and protocol, and has a negative impact on the perception data transmission delay.
- AMF Access and Mobility Management Function
- the protocol plane exposure points are increased, which adds new risk points to the stable operation of the network and network security.
- NF Network Function
- the current technical solutions usually use network management channels or transmission protocol interfaces, such as Xn interface to other base stations or N2 interface, N3 interface to the core network. Since there are no other channels for two-way data transmission, the data distribution and native intelligent expansion of base stations are limited.
- base stations Under the current network management system, base stations have the ability to communicate with management nodes, but to achieve communication between base stations and other network elements or NR (5G) nodes, the network management system cannot be used.
- the network management system needs to be isolated from the business system to ensure that the business system is not affected by the management system.
- a special data transmission channel can be isolated from the backhaul link to achieve data transmission and reception (first hop) between the base station and the anchor node, and the target node data is forwarded through the anchor node routing.
- this solution requires special configuration and transmission resource reservation at the base station and anchor node.
- the configuration for roaming or slicing scenarios is complex, and it lacks flexibility and scalability.
- the anchor node function is similar to the core network user plane gateway function, which makes the network networking complex and difficult to manage, increases the network's attack surface, and cannot reuse the various authentication, encryption and other existing mechanisms of the terminal and the network. As a result, this method cannot communicate directly with the terminal served by the base station.
- the base station external real terminal solution To achieve base station data distribution, you can also use the base station external real terminal solution to communicate with other network function nodes through the terminal.
- the external terminal solution needs to occupy valuable air interface resources and is close to the base station, causing interference to the base station's transmission and reception.
- it creates additional complexity and cost for the installation and deployment of the base station, such as the need to power the terminal and add an additional installation antenna.

- This mechanism allows the proxy terminal to save the antenna, intermediate frequency and baseband signal processing hardware, reduce product cost and complexity, and provide a low error and high reliability channel without occupying precious air interface resources. At the same time, it has the security of terminal access authentication and the large bandwidth, high reliability and low latency characteristics of cellular network data transmission. Generally speaking, the proxy terminal performs channel staking at the physical layer or data link layer to achieve direct interaction of PDU data.
- the proxy terminal can save the antenna, intermediate frequency and baseband signal processing hardware, thereby reducing product cost and complexity, and providing a low-error and highly reliable channel without occupying precious air interface resources, thereby reducing the strong dependence of physical layer signal processing between the proxy terminal and the base station on hardware, and realizing direct channel connection between the proxy terminal and the base station.
- the process of establishing a bidirectional data transmission channel includes steps 201 to 203:
- Step 201 the proxy terminal connects each channel of the preset piling layer with each channel of the preset piling layer in the base station one by one through inter-process communication according to the protocol followed by each channel, so as to obtain each connection channel of the preset piling layer, where the preset piling layer is at least one of each sublayer of the physical layer and each sublayer of the data link layer.
- inter-process communication can be used to propagate or exchange information between different processes.
- the preset piling layer is at least one of the sublayers of the data link layer (L2).

This application can enable the base station to transmit peripheral data to the target node through the proxy terminal without destroying the current network architecture and protocol system.
- the core idea of this application is that the base station data is sent and received through the terminal (proxy terminal), and the terminal (proxy terminal) assists in forming a data tunnel to provide data distribution to the base station, and the terminal (proxy terminal) still transmits data through the base station, transmission network, and core network according to the normal access process.

近年来,随着自动驾驶、无人机、XR(Extended Reality,扩展现实)、工业互联网等技术不断发展,未来智能应用对网络,尤其是无线网络提出了更多维度的极致性能需求。这需要突破通信本身的范畴,将传统定位、探测、成像等无线感知功能同无线通信功能深度融合,实现通信感知计算的交叉融合。
人工智能在近十年发展迅速,在挖掘大数据样本的非线性规律、与环境交互的在线精准决策方面超过了以人工为主的专家经验模式,在计算机视觉、自然语言处理、机器人控制等领域取得了巨大进步。从5G开始,人工智能在移动通信中也逐渐得到了广泛应用,从网络配置优化到资源调度,甚至空口物理层的智能化都引入了人工智能。5G网络智能化大多数使用外挂AI(Artificial Intelligence,人工智能)的模式,算力、数据、模型和通信连接属于不同技术体系,未定义规范的接口和交互规则,跨域技术协同只能通过管理面拉通进行,导致秒级甚至分钟级时延,服务质量也难以得到有效保障。
在通信、感知、计算融合和人工智能融入无线网络背景下,基站能力得到了增强,融入原生AI、边缘计算、感知能力,变得更加的智能。基站侧采集到的各种信息需要在网络各功能网元间分发传递以进行协同处理,或者上传给能力开放节点以提供给第三方APP(Application,应用)使用,这些数据的分发需要高效、灵活、低时延、安全的通道或方法来承载。
目前,对于通信感知融合场景,当前仍处于研究探讨阶段,业内尚未形成统一观点。基于目前已知研究进展和标准推进方向,主流观点为最大化复用5GC功能网元接口,新增具备控制、计算能力的通信感知功能单元,提供能力开放功能。通信感知融合系统整体架构如图1所示,图1中,应用层功能(Application Function,AF)网元与网络开放功能(Network Exposure Function,NEF)网元通过接口连接,NEF网元和通信感知融合功能网元通过Nx接口(5G接口)连接,通信感知融合功能网元与移动性管理功能(Access and Mobility Management Function,AMF)网元通过Ny接口(5G接口)连接,通信感知融合功能网元与用户面功能(The User Plane Function,UPF)网元通过N6接口(5G接口)连接,AMF网元通过N2接口(5G接口)向基站(通感一体化基站)传输感知控制指令,基站通过N3接口(5G接口)向UPF网元进行感知数据上报。图1中,新增的通信感知融合功能网元,负责感知功能的管控、感知信息的计算和开放。其中,管控主要体现在对AMF网元感知功能进行管理控制;计算主要体现在对上报的感知信息的智能化计算处理;开放体现为对感知信息和数据对网络内部或网络外部开放。
在控制面协议栈中,对AMF进行功能增强,具备通信感知功能,同时在通信感知融合功能网元增加南北向接口,与NEF网元对外能力开放的Nx接口(5G接口),调用AMF的Ny(5G接口)接口,并复用N2接口(5G接口)。其中,通过Nx接口实现通过NEF对外部应用或网络内部NF感知能力调用、感知结果上报;通过Ny接口实现通信感知融合网元对AMF感知功能控制;通过N2接口,实现AMF对基站感知功能的控制,AMF将通信感知融合网元功能的控制指令转发给基站(通感一体化基站)。
在用户面协议栈中,复用N3接口(5G接口)、N6接口(5G接口),其中,基于N3接口将基站(通感一体化基站)感知数据上报,基于N6接口将基站(通感一体化基站)获取的感知数据转发给通信感知融合功能网元。
对于基站智能化场景,当前并未定义明确的接口和协议来支持数据的交互和处理。如果通过扩展管理面来实现,会增大时延,且不够灵活。基站管理面主要通过网管系统对基站进行管控和参数搜集。基站之间可通过Xn接口(5G接口)或X2(5G接口)口交互数据实现协同,基站和核心网网元通过N2或S1接口(5G接口)交互控制数据,如果要分发数据到智能化处理节点(或网元),需要核心网相关网元转发,交互流程过长,逻辑复杂,且需要修改当前接口协议。
对于基站本地采集、融合的感知数据下发到基站所服务终端的场景,例如C-V2X(Cellular Vehicle-to-Everything,车联网)应用场景,当前系统和协议并不支持基站和终端进行感知数据等应用层数据交互,需要边缘计算来实现和终端的感知数据交互。由于基站数量巨大,很难实现每个基站都部署核心网用户面网元或边缘计算单元,造成当前网络部署方式很难实现低成本、低时延的感知数据下发。
为实现通信感知一体化、增强基站智能化,需要在基站实现高效数据分发,例如基站侧视频回传、环境监控数据回传、感知数据回传、空天基站无人机数据回传、融合感知网
元和基站双向通信、基站数据下发终端等。
对于通信感知一体化,现有技术方案在核心网中新增通信感知融合网元,并复用现有蜂窝系统的控制面和用户面来实现通信感知融合网元和基站之间的控制指令和感知数据传输。虽然此方案能实现融合感知网元和基站之间数据分发,但需要增强AMF(Access and Mobility Management Function,接入和移动性管理功能)功能并新增接口,提高了接口和协议复杂度,同时对感知数据传输时延产生负面影响。另外,AMF功能扩展后,增加了协议面暴露点,对网络稳定运行和网络安全增加了新的风险点。
要增加基站的智能水平,需要基站和其他网元或NF(Network Function,网络功能)交互数据,当前技术方案通常走网管通道或传输协议接口,如Xn接口到其他基站或N2接口、N3接口到核心网。由于没有其他通道可实现双向数据传输,从而限制了基站数据分发和原生智能扩展。在当前网管系统体系下,基站具备和管理节点通信能力,但要实现基站和其他网元或NR(5G)节点通信,无法使用网管系统,网管系统需要和业务系统之间互相隔离,保障业务系统不受管理系统的影响。
与网管系统类似,要实现基站侧数据收发,可以从回传链路隔离出一个专门数传通道,实现基站和锚定节点的数据收发(首跳),目标节点数据通过锚定节点路由转发。一方面此解决方案需要在基站和锚定节点做专门的配置和传输资源预留,数据目标节点种类繁多,路由转发路径复杂,对于漫游或者切片等场景配置复杂,缺乏灵活性和扩展性;另一方面,锚定节点功能类似于核心网用户面网关功能,造成网络组网复杂和难于管理,增加了网络的被攻击面,不能复用终端和网络的各种鉴权、加密等现有机制;如此,此方法无法很好的和基站下服务的终端进行直接通信。
要实现基站数据分发,还可以采用基站外接真实终端方案,通过终端实现和其他网络功能节点通信。不过外接终端方案,需要占用宝贵的空口资源,而且距离基站较近,对基站收发造成干扰,同时对基站安装部署产生额外的复杂度和成本,例如需要给终端供电、新增安装件天线等。
基于此,本申请实施例提供一种基站数据传输方法,本申请的核心思想是在基站上实现一个代理终端,使得基站不是只作为网络服务商的接入设备,任何通信只能通过核心网接口协议进行协议转换来实现,还兼有终端数传能力,基站可以实现与任何网络功能节点(包括网络的各种终端)的点对点双向通信,从而极大的扩展了基站和其它功能节点数据传输的灵活性和安全性。另外,使得基站具备网络层及以上的传输层、应用层数据通信功能,可以便捷、高效、安全的和其他功能节点直接通信。
本申请实施例提供一种基站数据传输方法,如图2所示,该方法应用于代理终端,其中,代理终端具备与基站、目标终端以及核心网进行通信的能力;该方法包括步骤101至步骤102:
步骤101、代理终端接收基站通过已构建的双向数传通道传输的基站数据;双向数传通道为代理终端与基站实现对等层之间数据交互的通道。
在本申请的一些实施例中,代理终端和基站为一对一的关系,代理终端可以为基站中部署的软件功能模块,代理终端也可以通过网线、USB(Universal Serial Bus,串行总线)接口等其他硬件接入的方式实现代理终端与基站的互联,本申请实施例对代理终端接入基站的方式不作任何限制,具体可以根据实际应用场景确定。
在本申请的一些实施例中,代理终端具备与基站、目标终端以及核心网进行通信的能
力,代理终端具备完整的TCP/IP协议栈和终端通信能力,并遵循3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)协议。
在本申请的一些实施例中,基站数据为基站内部数据和基站外部数据中的至少一种,其中,基站内部数据为基站中产生和/或采集的数据;基站外部数据为通过接口向基站传输的数据。
这里,基站中内置的各种功能模块可以包括参数采集模块、原生智能模块、感知模块、网元协同模块的至少一种。如此,基站内部数据可以为包括参数采集模块、原生智能模块、感知模块、网元协同模块等基站内部功能模块和其他网络功能模块(网络功能节点)交互的数据。另外,基站内部数据还可以包括基站在处理过程中产生和/或采集的处理数据。
需要说明的是,基站内部数据可以理解为基站自身产生和处理的数据,包括但不限于感知通信融合模块(或者感知模块)、参数采集模块、原生智能模块、网元协同模块等基站内部功能模块和其他各网络功能节点(根据实际场景集中式或分布式部署的)交互的数据。
基站通过提供接口为外部数据源模块提供数据传输通道,外部功能模块通过该数据传输通可以实现与目标终端或者目标网络节点的双向通信。这里,外部功能模块可以为各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户终端设备(terminal device)等等。
需要说明的是,外部功能模块也称为外部数据源,外部数据源是指基站通过接口给外设提供数传通道,外设通过此通道和目的节点(目标终端或者目标网络节点)进行双向通信的数据。
步骤102、代理终端通过核心网将基站数据发送至目标网络节点,以进行基站与目标网络节点的数据交互;或者,代理终端将基站数据发送至目标终端,以进行基站与目标终端的数据交互。
在本申请的一些实施例中,目标网络节点包括以下至少一项:资源协同网元、感知网元、智能处理网元和能力开放网元。这里,目标网络节点不限于上述提到的各种网络功能节点,目标网络节点还可以为任意一个需要和基站进行双向通信的第三方应用平台或者服务器。目标终端为接入基站的终端,可以为各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户终端设备等等。本申请对此不作任何限制。
基站数据通过代理终端和远端的目标网络节点或者目标终端进行双向通信,代理终端在上述通信过程中扮演着数据网关的作用。当基站数据从基站内部(各种内置的功能模块)或者外部功能模块通过双向数传通道路由到代理终端时,代理终端通过核心网把数据分发到目标网络节点或者目标终端对应的目标地址;反之,目标网络节点或者目标终端通过反方向寻址将数据发送至代理终端,代理终端将接收到的数据转发至基站内部的各个功能模块或者外部功能模块。
本申请还可以解决基站外部功能模块和接入基站的终端(代理终端)间通信。按正常流程,基站代理终端(代理终端)可以直接和真实终端(目标终端)点对点通信实现数据交换。对于无人驾驶等需要广播基站侧搜集的感知数据的场景,感知数据(融合处理后)通过基站代理终端和基站空口协议处理模块的自定义通道传递到基站对应小区的广播信道队列中,再广播到小区中,可以极大降低感知数据分发时延。
示例性的,以无人驾驶的应用环境为例,广播基站侧(基站)将搜集到的无人驾驶需要的感知数据(融合处理后)通过代理终端的双向数传通道直接推送到对应小区的广播信道队列中,通过广播信道利用广播或者多播的方式将感知数据发送到对应的无人驾驶汽车中。
本申请中的代理终端可理解为基站中部署的软件功能模块,一方面通过接入所属的基站获取网络数传服务,另一方面具有真实终端的数传功能和网关数据交换功能,提供数传通道给基站以实现基站数据分发。代理终端为接入基站获取数传服务,具有终端的接入层AS和非接入层NAS协议处理能力。
可以理解的是,一方面,代理终端通过接入所属的基站获取网络数传服务,使得基站具有终端的接入层(Access Stratum,AS)以及非接入层(Non-Access Stratum,NAS)功能。另一方面,代理终端具有真实终端的数据传输功能和网关数据交换功能,为基站提供双向数据传输通道从而实现基站数据的分发。又一方面,从核心网角度看(或者从基站角度看),代理终端具备普通终端的网路接入和数据传输功能,支持控制面和用户面协议。例如,针对NAS信令和数据传输流程,NAS实现完全遵循3GPP协议规范,代理终端可以保障数据传输的安全性以及对应的QoS(Quality of Service,服务质量)需求。再一方面。在实现代理终端的同时,基站接入网功能实现需要感知代理终端的存在,并对代理终端做适配处理,在有些功能实现时可做简化处理。
需要说明的是,这里的简化处理根据具体的实施方式可以进行灵活剪裁,在一般情况下,代理终端的一些功能模块可以全量参照普通终端的实现。但是由于代理终端的特殊性,一些功能模块可以进行简化处理,降低协议实现的复杂度。比如,移动性管理模块、测量配置模块、无线资源调度分配模块等。也就是说,代理终端可以不作任何切换处理,基站可以不下发测量配置信息给代理终端,基站与代理终端也可以不做任何无限资源调度处理。
需要说明的是,本申请实施例的基站数据传输方法可以应用第四代移动通信系统(the 4th generation mobile communication system,4G)、第五代移动通信技术(5th-Generation wireless communication technology,5G)新空口(New Radio,NR)系统或未来的通信系统,也可以用于其他各种无线通信系统,例如:窄带物联网(Narrow Band-Internet of Things,NB-IoT)系统、全球移动通讯系统(Global System of Mobilecommunication,GSM)、增强型数据速率GSM演进(Enhanced Data rate for GSM Evolution,EDGE)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、码分多址2000(Code Division Multiple Access,CDMA2000)系统、时分同步码分多址(Time Division-Synchronization Code Division Multiple Access,TD-SCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)等。
在本申请实施例中,双向数传通道为代理终端与基站实现对等层之间数据交互的通道,代理终端可以通过信道打桩,将自身与基站的对等层的各个信道进行对接,以建立代理终端与基站之间的双向数传通道。
代理终端需要实现终端的AS协议和NAS协议,其中NAS协议与普通终端的实现方式一样,针对AS协议部分,代理终端无需实现物理层信号的处理,通过信道打桩实现代理终端与基站AS空口对等层协议通信,可以理解的是,双向数传通道可以实现代理终端
与基站AS空口对等层协议通信。
需要说明的是,信道打桩可以理解为建立内部两个功能模块或者协议实体之间的直通数据通道,这里的直通数据通道也称为数据传输通道或者双向数传通道。从基站角度(或核心网角度)来看,代理终端需要实现AS控制面和用户面功能,空口接入层(AS层)实现也遵循3GPP协议。双向数传通道使得代理终端与基站之间的L1层(物理层)的信号处理部分无需实现,代理终端直接通过在L2层(数据链路层)以上信道打桩实现各个信道的对接,进而实现协议PDU(Protocol Data Unit,协议数据单元)数据交互,此机制可以让代理终端省去天线、中射频和基带信号处理硬件,降低产品成本和复杂度,不占用宝贵的空口资源便提供低误码高可靠信道,同时兼有终端接入鉴权认证的安全性和蜂窝网络数传大带宽、高可靠、低时延特性。一般来说,代理终端在物理层或者数据链路层进行信道打桩,从而实现PDU数据的直接交互。
如此,通过信道打桩,可以让代理终端省去天线、中射频和基带信号处理硬件,进而降低产品成本和复杂度,不占用宝贵的空口资源便可提供低误码高可靠的信道,从而降低代理终端与基站之间物理层信号处理对硬件的强依赖,实现代理终端与基站的信道直通。
在本申请实施例中,如图3所示,建立双向数传通道的过程包括步骤201至步骤203:
步骤201、代理终端通过进程间通信,将预设打桩层的各个信道与基站中预设打桩层的各个信道,按照各个信道遵循的协议进行一一对接,得到预设打桩层的各个对接信道,预设打桩层为物理层的各个子层以及数据链路层的各个子层的至少一种。
在本申请的一些实施例中,进程间通信(Inter-Process Communication,IPC)可以实现在不同进程之间传播或交换信息。通常情况下,预设打桩层为数据链路层(L2)的各个子层的至少一种,这是由于信道打桩的目的是为了降低物理层信号处理对硬件的强依赖,因此预设打桩层位于七层网络模型中网络层以下,以实现基站与代理终端之间的数据分发。
需要说明的是,在NR网络的L2层的网络模型中,由下往上依次为:介质访问控制层(Media Access Control,MAC)、无线链路控制层(Radio Link Control,RLC)、分组数据汇聚层(Packet Data Convergence Protocol,PDCP)、服务数据应用(Service Data Adaptation Protocol,SDAP)。
在本申请的一些实施例中,预设打桩层也可以为物理层的各个子层的至少一种,通过对代理终端的物理层进行打桩来实现代理终端与基站之间的数据分发。
在本申请的一些实施例中,代理终端和基站还可以通过控制面或者用户面解耦的方来实现代理终端与基站之间的数据分发,比如,代理终端和基站可以从控制面协议栈的L1层和L2层进行打桩,以及用户面协议栈的L2层进行打桩。
步骤202、代理终端将承载在预设打桩层之外的各个信道,按照各个信道遵循的协议进行信道映射,得到预设打桩层之外的各个对接信道。
在本申请的一些实施例中,预设打桩层之外的各个信道指的是,OSI模型(Open System Interconnection Reference Model,开放式系统互联通信参考模型)中预设打桩层之上的各个层的各个信道。OSI模型的层次划分由下至上依次为:物理层(Physical Layer)、数据链路层(Data Link Layer)、网络层(Network Layer)、传输层(Transport Layer)、表达层(Presentation Layer)以及应用层(Application Layer)。示例性的,若预设打桩层为数据链路层,此时,预设打桩层之上(或者预设打桩层之外)的各个层为网络层、传输层、表达层以及应用层。那么,预设打桩层之上(或者预设打桩层之外)的各个信道为网络层、传
输层、表达层以及应用层中的各个信道。
作为一种可实现的方式,首先,代理终端针对自身与基站中承载在预设打桩层之外的各个层的各个第一信道,按照各个第一信道遵循的3GPP协议进行信道映射,得到第一对接信道,第一信道为代理终端与基站的控制面协议栈中的信道。然后,代理终端针对自身与基站中承载在预设打桩层之外的各个层的各个第二信道,按照各个第二信道遵循的3GPP协议进行信道映射,得到第二对接信道,第二信道为代理终端与基站的用户面协议栈中的信道;最后,代理终端根据第一对接信道以及第二对接信道,得到预设打桩层之外的各个对接信道。
在实现代理终端与基站的预设打桩层的各个信道对接之后,将承载在预设打桩层之上的各个逻辑信道以及各个传输信道进行信道映射,信道映射遵循3GPP协议。由于代理终端与基站之间无需实现物理层信号处理,因此,基站也无需进行无线资源调度分配,传输信道以及逻辑信道通过内部信道承载。代理终端与基站进行数据分发(数据传输、通信)时,可以不考虑误码产生的数据重传(Hybrid Automatic Repeat Request,数据重传),从而可以认为物理层是可靠、低时延且带宽不受限的理想信道。需要说明的是,代理终端的传输速率、时延收到QoS配置和基站回传链路的约束。
步骤203、代理终端基于预设打桩层的各个对接信道以及预设打桩层之外的各个对接信道,建立代理终端与基站之间的双向数传通道。
代理终端需要实现终端的AS和NAS协议,其中NAS和正常终端的协议实现一样,AS部分无须实现物理层信号处理,通过信道打桩对接,实现和基站AS空口对等层协议通信,各信道协议实现参考3GPP协议。下面以5G系统为例描述移动终端的信道打桩实现方法,其他网络制式(4G或者未来演进的6G、7G等网络制式)可参考类似方法实现。
作为一种实施方式,预设打桩层为数据链路层的各个子层中的介质访问控制MAC层;MAC层的各个信道包括以下至少一种:上行共享信道ULSCH、随机接入信道RACH、下行共享信道DLSCH、寻呼信道PCH和广播信道BCH。
图4为本申请实施例提供的一种MAC层的对接信道示意图,如图4所示,代理终端将自身的ULSCH通过IPC实现与基站的ULSCH的数据传输,完成自身的ULSCH与基站的ULSCH的对接,以建立代理终端与基站的ULSCH的对接信道,自身的ULSCH与基站的ULSCH遵循相同的协议;将自身的RACH通过IPC实现与基站的RACH的数据传输,完成自身的RACH与基站的RACH的对接,以而建立代理终端与基站的RACH的对接信道,自身的RACH与基站的RACH遵循相同的协议;将自身的DLSCH通过IPC实现与基站的DLSCH的数据传输,完成自身的DLSCH与基站的DLSCH的对接,以建立代理终端与基站的DLSCH的对接信道,自身的DLSCH与基站的DLSCH遵循相同的协议;将自身的PCH通过IPC实现与基站的PCH的数据传输,完成自身的PCH与基站的PCH的对接,以建立代理终端与基站的PCH的对接信道,自身的PCH与基站的PCH遵循相同的协议;将自身的BCH通过IPC实现与基站的BCH的数据传输,完成自身的BCH与基站的BCH的对接,以建立代理终端与基站的BCH的对接信道,自身的BCH与基站的BCH遵循相同的协议;ULSCH的对接信道、RACH的对接信道、DLSCH的对接信道、PCH的对接信道以及BCH的对接信道中的至少一种:为MAC层的各个对接信道的公共信道。
代理终端通过在MAC层进行信道打桩,通过IPC实现代理终端与基站之间各个信道的对接,各个信道根据遵循的3GPP协议进行一一对接,可以理解的是,各个对接信道遵
循相同的3GPP协议规范。
代理终端在完成MAC层的各个信道与基站中MAC层的各个信道按照各个信道遵循的协议进行一一对接之后,得到MAC层的各个对接信道之后。代理终端针对自身与基站中承载在MAC层之外的各个层的各个第一信道,按照各个第一信道遵循的3GPP协议进行信道映射,得到第一对接信道。与此同时,代理终端针对自身与基站中承载在MAC层之外的各个层的各个第二信道,按照各个第二信道遵循的3GPP协议进行信道映射,得到第二对接信道。
需要说明的是,第一对接信道为代理终端与基站的控制面协议栈中的信道,第二信道为代理终端与基站的用户面协议栈中的信道。
图5为本申请实施例提供的一种MAC层的控制面协议栈(也称为控制面点端到端协议栈)的示意图,如图5所示,代理终端(agent UE)在L2层中的MAC层通过IPC实现信道打桩,使得代理终端(agent UE)与基站(gNodeB)之间的MAC层的各个信道实现对接。图5中,NAS-SM为NAS-MM为NAS层中的两个功能层,遵循3GPP协议。SCTP(Stream Control Transmission Protocol,流控制传输层)/(IP Internet Protocol,网络互连协议)、NG-AP(Access Point,无线接入点)遵循3GPP协议。基站与AMF(Access and Mobility Management Function,接入和移动性管理功能)和SMF(Session Management function,会话管理功能)通过5G核心网的N2接口进行连接。代理终端(agent UE)在L2层中的MAC层通过IPC实现MAC层的各个信道的对接之后,代理终端与基站的承载在MAC层之上的各个层(RLC、PDCP、RRC)遵循3GPP规范进行信道映射,代理终端与AMF和SMF之间的各个信道遵循3GPP规范进行信道映射,基站与AMF和SMF之间的各个信道遵循3GPP规范进行信道映射。
图6为本申请实施例提供的一种MAC层的用户面协议栈(也称为用户面点端到端协议栈)的示意图,如图6所示,代理终端在用户面协议栈的MAC层通过IPC进行信道打桩,使得代理终端与基站的用户面协议栈的MAC层的各个信道实现对接。代理终端的承载在MAC层之上的RLC层、PDCP层(Packet Data Convergence Protocol,分组数据汇聚协议)、SDAP层(Service Discovery Application Profile,发现应用规范)遵循3GPP协议规范进行信道映射。代理终端的PDU Layer(Protocol Data Unit,协议数据单元)、5G核心网中的UPF(User Plane Function,用户面功能)网元以及5G核心网的DN(Data Network,数据网络)网元通过遵循3GPP协议规范进行信道映射,代理终端与UPF通过5G核心网的N3接口进行连接,UPF与DN通过5G核心网的N6接口进行连接。代理终端的APP层(Application,应用层)与5G核心网的DN网元通过遵循3GPP协议规范进行信道映射。基站与UPF网元的L1层、L2层、UDP(User Datagram Protocol,用户数据报协议)/IP层、GTP-U(GPRS Tunneling Protocol-User,用户隧道协议)的各个信道通过遵循3GPP协议规范进行信道映射。UPF网元和DN网元的L1层、L2层、PDU Layer的各个信道通过遵循3GPP协议规范进行信道映射。
在本申请实施例中,在实现了代理终端和基站间传输信道打桩对接后,承载在其上的各逻辑信道和传输信道映射以及各层协议实现参考3GPP协议。由于无须实现物理层信号处理,基站无须进行无线资源调度分配,传输信道通过内部通道承载,不考虑误码产生的数据重传(HARQ),可以认为物理层是可靠、低时延且带宽不受限的理想信道。代理终端传输速率、时延受QoS配置和基站回传链路约束。
作为另一种实施方式,预设打桩层为数据链路层的各个子层中的无线链路控制RLC层;RLC层的各个信道包括以下至少一种:专用业务信道DTCH、公共控制信道CCCH、专用控制信道DCCH、寻呼控制信道PCCH和广播控制信道BCCH。
图7为本申请实施例提供的一种RLC层的对接信道示意图,如图7所示,代理终端(agent UE)将自身的DTCH通过IPC实现与基站(gNodeB)的DTCH的数据传输,完成自身的DTCH与基站的DTCH的对接,以建立代理终端与基站的DTCH的对接信道,自身的DTCH与基站的DTCH遵循相同的协议;代理终端将自身的CCCH通过IPC实现与基站的CCCH的数据传输,完成自身的CCCH与基站的CCCH的对接,以建立代理终端与基站的CCCH的对接信道,自身的CCCH与基站的CCCH遵循相同的协议;代理终端将自身的DCCH通过IPC实现与基站的DCCH的数据传输,完成自身的DCCH与基站的DCCH的对接,以建立代理终端与基站的DCCH的对接信道,自身的DCCH与基站的DCCH遵循相同的协议;代理终端将自身的PCCH通过IPC实现与基站的PCCH的数据传输,完成自身的PCCH与基站的PCCH的对接,以建立代理终端与基站的PCCH的对接信道,自身的PCCH与基站的PCCH遵循相同的协议;代理终端将自身的BCCH通过IPC实现与基站的BCCH的数据传输,完成自身的BCCH与基站的BCCH的对接,以建立代理终端与基站的BCCH的对接信道,自身的BCCH与基站的BCCH遵循相同的协议;DTCH的对接信道以及DCCH的对接信道的至少一种:为RLC层的各个对接信道的专用信道;CCCH的对接信道、PCCH的对接信道以及BCCH的对接信道中的至少一种:为RLC层的各个对接信道的公共信道。
代理终端通过IPC在RLC层进行信道打桩,从而实现代理终端和基站在RLC层的各个逻辑信道的对接,各个信道根据遵循的3GPP协议进行一一对接,可以理解的是,各个对接信道遵循相同的3GPP协议规范。如图7所示,信令无线承载(Signalling Radio Bearer,SRB)对应的逻辑信道的连接实现空口RLC层控制数据协议的对接,数据无线承载(Data Radio Bearer,DRB)对应的逻辑信道的连接实现空口RLC层用户业务数据协议的对接。代理终端与普通终端一样,代理终端需要创建数据无线承载DRB和信令无线承载SRB来实现业务数据和控制信令的传输。需要注意的是,数据无线承载DRB的数量根据RRC(Radio Resource Control,无线资源控制)配置信令来动态创建和配置。
代理终端在完成RLC层的各个信道与基站中RLC层的各个信道按照各个信道遵循的协议进行一一对接之后,得到RLC层的各个对接信道之后。代理终端针对自身与基站中承载在RLC层之外的各个层的各个第一信道,按照各个第一信道遵循的3GPP协议进行信道映射,得到第一对接信道。与此同时,代理终端针对自身与基站中承载在RLC层之外的各个层的各个第二信道,按照各个第二信道遵循的3GPP协议进行信道映射,得到第二对接信道。
图8为本申请实施例提供的一种RLC层的控制面协议栈的示意图,如图8所示,代理终端(agent UE)在L2层中的RLC层通过IPC实现信道打桩,使得代理终端与基站控制面协议栈的RLC层的各个信道实现对接。代理终端与基站中承载在RLC层之上的各个层通过遵循3GPP协议规范进行对等层之间的信道映射。对于控制面端到端协议栈(也称为控制面协议栈),和3GPP协议栈的区别在于空口协议栈部分。一般情况下,RLC层的逻辑信道需要映射到MAC层的传输信道进行数据封装传输,在实现代理终端时,代理终端的RLC层的各个逻辑信道与基站的RLC层的各个逻辑信道进行对接。控制面协议栈主要
是代理终端的SRB0、SRB1、SRB2对应的控制信道、BCCH、PCCH与基站对应的各个逻辑信道进行对接。需要说明的是,控制面协议栈的RLC以及承载在RLC层之上的各个层(PDCP、RRC)遵循3GPP协议规范进行对等层之间的通信。
图9为本申请实施例提供的一种RLC层的用户面协议栈的示意图,如图9所示,代理终端在L2层中的RLC层通过IPC实现信道打桩,使得代理终端与基站用户面协议栈的RLC层的各个信道实现对接。代理终端与基站中承载在RLC层之上的各个层通过遵循3GPP协议规范进行对等层之间的信道映射。对于用户面协议栈,端到端流程与3GPP协议栈类似,差异点在于空口协议栈部分,用户面协议栈的RLC层承载了用户的业务数据。用户面协议栈与控制面协议栈一样,3GPP协议定义了RLC逻辑信道和MAC传输信道之间通过映射和解映射来实现RLC层的PDU数据的发送接收对应的数据封装和解封装。RLC层中各个逻辑业务信道根据RRC重配置信令创建的DRB实体来承载。在RLC层的信道打桩方案下,用户面协议栈的RLC层的各个逻辑业务信道直接和基站的RCL层的各个逻辑业务信道进行对接,从而实现RLC层的SDU(Service Data Unit,服务数据单元)的收发。也就是说,代理终端或者基站在RLC层无须将SDU封装成PDU(Protocol Data Unit,协议数据单元)发送给MAC层,同样的,代理终端或者基站在MAC层也无须将接收的PDU进行解封装成SDU。
需要说明的是,上述以5G系统为例描述代理终端的信道打桩实现方法仅为一种示例,信道打桩方法的选择需要根据实际的应用场景进行选择。基站内部进程间通信IPC的实现可以根据基站自身的软件以及硬件的架构来确定。可以理解的是,基站内部IPC的实现可以是芯片内进程间通信,也可以为跨芯片的进程间通信。本申请实现的代理终端具备和基站、核心网完整的控制面信令交互能力,以及和基站、核心网完整的用户面数传能力,支持核心网控制面、用户面分离,支持边缘计算以及各种类型网络切片。代理终端从协议完备性、一致性和正常UE并无差异,只是空口协议栈实现可裁剪(不实现物理层,MAC和RLC层实现根据配置确定)。
在本申请实施例中,如图10所示,步骤101包括步骤301至步骤302:
步骤301、在代理终端处于开机状态时,代理终端通过双向数传通道中的公共信道,向基站发送随机接入信息。
在本申请的一些实施例中,代理终端与基站建立双向数传通道之前,使用人员将代理终端设置为开机状态。
作为一种可实现的方式,在代理终端处于开机状态时,代理终端与基站的RLC层的各个公共通道通过IPC进行对接,RLC层的各个公共通道可以为RACH、CCCH、BCCH、PCCH等。代理终端通过双向数传通道的公共通道,向基站发送随机接入信息。
步骤302、代理终端基于随机接入信息,完成与基站的随机接入过程,并通过构建的双向数传通道中的专用信道,接收基站传输的基站数据。
作为一种可实现的方式,基站通过双向数传通道的公共通道接收到代理终端发送的随机接入信息,基于随机接入信息,代理终端完成与基站的随机接入过程。随后,基站基于双向数传通道的专用信道向代理终端发送基站数据,双向数传通道的专用信道可以为DCCH、DTCH,代理终端基于双向数传通道的专用信道接收基站发送的基站数据。
在本申请实施例中,如图11所示,步骤102包括步骤401至步骤403:
步骤401、代理终端基于无线电接入网协议,将基站数据发送至核心网。
无线电接入网(Radio Access Network,RAN)是移动通信系统中的一部分,是无线电接入技术的实现,RAN存在于一个设备(例如,移动电话、计算机或任何被远程控制的机器)与核心网之间,提供设备与核心网之间的通信连接。
步骤402、在核心网的鉴权认证结果为通过的情况下,建立与核心网的连接。
步骤403、在与核心网连接成功的情况下,通过核心网将基站数据发送至目标网络节点,进行基站与目标网络节点的数据交互。
作为一种可实现的方式,核心网对代理终端的身份信息进行鉴权认证,若核心网对代理终端的鉴权认证结果为通过,则代理终端建立与核心网的连接。
作为一种代理终端身份识别和用户签约信息方案,代理终端在核心网看来是一个真实存在的终端,对于代理终端的接入认证以及用户上下文信息的存储,核心网可以根据实际部署场景选择是采用和真实终端类似的SIM卡(Subscriber Identity Module,用户识别卡)或者eSIM卡(Embedded Subscriber Identity Module,嵌入式用户识别卡)来解决身份认证问题。另外,核心网还可以采用其他自定义的终端身份识别方案,在核心网中用户签约信息根据具体使用场景确定,例如:加密方案、用户QoS配置、计费方式、切片信息等等。
在本申请的一些实施例中,目标网络节点包括以下至少一项:资源协同网元、感知网元、智能处理网元和能力开放网元。

作为另一种可实现的方式,基于无线电接入网RAN协议,代理终端将基站数据发送至目标终端,代理终端接收目标终端发送的第二目标数据,并将第二目标数据转发至基站对应的目标模块,以进行基站与目标终端的数据交互,第二目标数据表征目标终端发送至目标模块的数据。

在本申请实施例中,代理终端在开机后通过IPC向基站发起注册,建立RACH、CCCH、BCCH、PCCH信道,基站对应也建立和代理终端通信的对应的IPC通道,然后代理终端和基站按照正常的随机接入流程开展后续的动作。在随机接入过程中,代理终端和基站建立DCCH、DTCH通道实现信令和业务的数据传输。代理终端和基站完成SRB和DRB建立后,需要进一步和核心网启动鉴权、认证、注册流程以完成入网。入网流程完成之后,代理终端可以和核心网进行数据传输业务,此时基站可以通过代理终端和目标节点(目标模块)进行双向通信。
需要说明的是,代理终端属于基站内部一个软件功能模块,在接入基站实现数据传输时,基站需要做相应的处理以支持和代理终端的信道打桩对接,并在某些功能实现时做相应的简化和适配,比如,移动性管理、测量配置、无线资源分配等等。
另外,基站对于代理终端的特殊处理在于和代理终端各逻辑信道的IPC通道打桩直接对接,可以理解的是,基站对于代理终端的特殊处理在于代理终端与基站的各个信道的通过IPC进行信道打桩进而实现各个信道的直接对接,而不是按照基站与常规终端从L1层(物理层)到L2层(无线链路层)的接口进行数据收发。预设打桩层(例如,L2中的MAC层和RLC层)及以上各层协议均和常规终端处理一样,基站与代理终端的用户上下文、同核心网交互的用户实例与普通终端无差别,均按照普通终端的方式实现。
此外,由于代理终端的特殊性,基站部分功能实现时需要做简化处理。代理终端是固定接入其对应的基站,移动性管理可以做简化处理,测量配置和上报可以省略或做简化处理,代理终端接入流程可以简化,代理终端无须做TA(Time Advanced,最大时间提前量)调整、重同步等。另外,代理终端无须做信道探测以及无线资源分配调度,同样代理终端也无须配置各种信道探测资源。由于代理终端和基站空口通信无须实现物理层,如此,基站做无线资源调度时不需要给代理终端分配空口RB(Resource Element,资源元素)资源和资源调度、链路自适应处理,基站的各物理信道也无须配置资源和实现。
需要说明的是,在传输信道打桩或逻辑信道打桩对接时需要确定MAC层PDU大小(针对MAC层信道打桩)或RLC层PDU大小(针对RLC信道打桩)以及TTI(Time to Interactive,互动时间)起点和间隔。由于代理终端和基站无须实现严格的时间同步,也不占用空口RB资源,如此,代理终端和基站之间在进行空口数据传输的时候,可以按照缓存情况按序收发数据。例如,每次MAC层PDU组包或RLC层PDU组包时,可以按照PDU和对应的SDU一比一的比例进行组包。
可以理解的是,一方面,基站具备终端通信能力,为基站内部的各个功能模块提供和远端目标节点的点对点通信能力,使得基站智能化。代理终端可以作为网关,为基站内各个功能模块的各种网络数据提供实时搜集和协同处理,各种智能化决策数据可以分发到基站实时执行,使得基站支持更加便捷地部署边缘计算、边缘存储、边缘智能等。一方面,基站具备终端通信能力,可以为基站外设提供点对点双向数传通道,支持通信、感知、计算、存储融合以及智能处理,把融合或无须融合的数据传输到目标节点(目标网络节点或者目标终端)。一方面,基站具备终端通信能力,可以和本基站服务的终端(外部功能模
块)直接通信,也可以和其他基站下的终端(目标终端)直接通信,在基站部署的各种融合感知系统可以通过基站快速、便捷、安全的和周围智能终端交互、协同,使能汽车、无人机等智能机器终端自动驾驶等特性大规模商用和部署。一方面,基站的终端功能通过代理终端实现,代理终端和基站之间空口协议栈通过信道打桩对接,信道打桩对接可通过进程间通信纯软件实现,无须实现空口物理层信号处理和额外硬件支撑。通过此机制,可实现高可靠,低时延,按需带宽和安全等级的双向数据通信,并降低产品实现复杂度和安装成本。
可以理解的是,在本申请实施例中,另一个方面,当前支持通信感知计算融合,需要扩展核心网网元功能和协议已支持通信感知功能网元和基站的数据通信,通过新增接口的方式会增加协议实现复杂度和增加传输时延,并且降低了网络部署灵活性。在未来服务化核心网和接入网时代,本申请支持基站直接和各功能网元通信,无疑降低了协议复杂度和数据传输时延,且具有相当大的灵活度。本申请对基站未来智能化引入也有很好的支持,由于基站直接具备和其他节点的点到点通信能力,和各种智能化网元,异构功能节点交互更加灵活高效,无须扩展传统的控制面节点协议和组网架构。再一个方面,如果使用网管系统来实现基站和其他功能节点数据分发和交互,会打破管理系统和业务系统界限,对安全和网络运行造成不可预知的问题和风险。同时,组网灵活性和数传时延对应用造成不可克服的障碍。本申请把基站数据通过代理终端到核心网端到端的通信方式,从组网灵活性(如边缘计算、服务化网络架构)、安全性、低时延高可靠等方面相较网络系统的方式具有较强的优势。再一个方面,针对基站外挂终端作为数据传输的锚点方案,本申请的代理终端无须进行空口信号传输,不会占用宝贵空口资源,不会对基站造成信号干扰,进而简化基站的安装部署。又一方面,当前网络架构和协议并不支持基站随路捎带数据到其他网络节点,本申请可以实现基站将外设数据通过代理终端回传数据到目标节点,且不破坏当前网络架构和协议体系。
本申请的核心思想是基站数据通过终端(代理终端)进行收发,终端(代理终端)辅助形成一个数据隧道提供给基站进行数据分发,终端(代理终端)还是按照正常的接入流程通过基站、传输网、核心网进行数据传输。另外本申请的核心思想还在于代理终端在实现时通过信道打桩和基站进行通信,从而降低对硬件的依赖并减小产品复杂度。
在通信感知一体化、基站智能化时代,基站自身的数据或基站外设的数据需要更多的其他网络节点或终端节点进行点对点数据交换,当前协议体系结构并不直接支持基站和这些节点通信,存在强烈的技术和市场需求。本申请首先可以在6G标准推进中提前进行布局,解决通感一体化和基站智能化基站和其他节点数据通信需求;其次在4G、5G基站中也可以实施,应用在无人驾驶、无人机基站等场景,尤其是无人机基站场景,把无人机作为基站的外设,可以实时把无人机采集的视频数据或其他传感数据回传到平台,并支持无人机远程操控以及飞行信息实时回传。当前无人机,不管是大型固定翼无人机、垂起固定翼无人机、直升机还是旋翼无人机均没有和基站互通的接口,无法通过基站进行数据回传,也无法结合基站信息融合处理。本申请可解决无人机基站在应急通信场景无人机飞行数据、视频、基站本身信息实时回传的需求,并通过基站数据通道远程操控无人机,实现通信、感知、控制一体化。
应当注意,尽管在附图中以特定顺序描述了本申请中方法的各个步骤,但是,这并非要求或者暗示必须按照该特定顺序来执行这些步骤,或是必须执行全部所示的步骤才能实
现期望的结果。附加的或备选的,可以省略某些步骤,将多个步骤合并为一个步骤执行,以及/或者将一个步骤分解为多个步骤执行等;或者,将不同实施例中步骤组合为新的技术方案。
