The high-speed railway currently operates at a speed of 300km/h and may develop to 500km/h in the future. The wireless communication coverage of high-speed railway has obvious characteristics: high train running speed, long running distance and complicated geographical environment. Therefore, new requirements for high-speed switching of broadband communication systems are put forward, and existing cellular mobile communication technologies will Restricted, the quality of service for voice communication has been greatly reduced, and even "information islands" in the high-speed railway environment have emerged.

列车内的 LTE UE ( User Equipment, 用户设备, 即终端设备 )进行通信, 为了 克服车厢的穿透损耗, 增加信号强度, 可以在车厢上部加装直放站(repeater ), 对信号进行放大。 FIG. 1 is a schematic structural diagram of a public network coverage mode in the prior art. In this manner, an external LTE (Long Term Evolved) cellular network is composed of an eNB (evolved Node B) and an EPC (Evolved Packet Core) device, which directly The LTE UE (User Equipment, ie, the terminal device) in the train communicates. In order to overcome the penetration loss of the car and increase the signal strength, a repeater can be installed in the upper part of the car to amplify the signal.

In this way, various types of APs (Access Points, access points;) are deployed inside the car, which are responsible for communicating with the terminal devices in the corresponding compartments of the car, and can also be used to support multiple modes simultaneously supporting multiple modes.

The LTE network cellular network outside the car serves as a backhaul to complete the relay function of communication between the terminal equipment in the car and the core network and the external network. The on-board processing module installed on the car is the core module of this deployment mode, which is used to realize the aggregation processing of different standard data in the car, and communicates through the backhaul network in a wireless manner. The on-board processing module is usually wired and in-vehicle.
AP连接。 需要指出的是, 采用 LTE作为 backhaul网络只是一种示意, 同样可 以采用其它制式的网络作为 backhaul网络。 AP connection. It should be pointed out that the use of LTE as a backhaul network is only an indication, and other networks can be used as the backhaul network.
在实现本发明实施例的过程中, 申请人发现现有技术至少存在以下问题: 公网覆盖方式的主要缺点在于如果未加装直放站, 列车车厢厢体较大的穿 透损耗将导致车险内终端信号较差, 通信质量较难保证, 其另外一个问题在于 针对车厢内不同制式的终端, 列车沿线都要部署对应制式的网络, 部署成本高 曰 In the process of implementing the embodiments of the present invention, the applicant finds that the prior art has at least the following problems: The main disadvantage of the public network coverage mode is that if the repeater is not installed, the large penetration loss of the train car body will lead to the car insurance. The internal terminal signal is poor, and the communication quality is difficult to guarantee.

具体实施方式 detailed description
如背景技术所述, 在高速移动的通信场景中, 由于实际参与数据传输的终 端设备可能归属于不同制式的网络, 因此, 为了实现多种制式的网络数据的传 输, 在高速移动的周边场景中需要匹配的建立各种制式的网络设施, 投入大且 涉及复杂度高。 As described in the background, in a high-speed mobile communication scenario, since the terminal device actually participating in the data transmission may belong to a network of different standards, in order to realize transmission of network data of various standards, in a peripheral scene of high-speed movement The network facilities that need to be matched to establish various standards are large in investment and involve high complexity.
所以, 现有技术方案中缺少一种投入少且能兼容多种制式的网络的数据通 信方案, 本发明为了解决这样的问题, 基于现有的车载***覆盖方式中的整体 架构, 提出了相应的数据传输方案。 Therefore, in the prior art solution, there is a lack of a data communication solution that is less invested and compatible with a plurality of types of networks. In order to solve such problems, the present invention proposes a corresponding architecture based on the overall architecture of the existing in-vehicle system coverage mode. Data transmission scheme.
如图 3所示, 为本发明实施例提出的一种高速移动通信的实现方法的流程 示意图, 该方法具体包括以下步骤: As shown in FIG. 3, it is a schematic flowchart of a method for implementing high-speed mobile communication according to an embodiment of the present invention, where the method specifically includes the following steps:
步骤 S301、 接收回程网络发送的封装后的一种或多种制式的数据。 Step S301: Receive data of one or more standards after encapsulation sent by the backhaul network.
在实际的应用场景中, 本步骤中所接收到的数据具体可以包括以下几种形 式: In an actual application scenario, the data received in this step may specifically include the following forms:
( 1 )按照不同制式分别封装的一种或多种制式的数据, 所述数据携带相 应的用户标识和业务标识。 (1) Data of one or more systems separately packaged according to different standards, the data carrying corresponding user identifiers and service identifiers.
( 2 )统一封装的一种或多种制式的数据, 所述数据携带相应的制式标识、 用户标识和业务标识。 (2) Data of one or more standards uniformly encapsulated, the data carrying a corresponding standard identifier, a user identifier, and a service identifier.
( 3 )按照不同业务分别封装的一种或多种制式的数据, 所述数据携带相 应的用户标识和制式标识。 (3) Data of one or more standards separately packaged according to different services, the data carrying a corresponding user identifier and a standard identifier.
需要说明的是, 无论上述的哪种形式, 其最关键的目的在于说明数据所对 应的制式、 用户和业务类型的信息, 其中, 制式和业务类型可以成为进行封装
的依据, 从而, 以封装数据的范围来实现不同制式或不同业务的数据的区分, 也可以通过添加标识的方式进行区分, 而对应不同用户的数据则只是通过添加 标识的方式进行区分, 具体应用上述的哪种形式可以根据实际需要进行调整, 这样的变化并不影响本发明的保护范围。 It should be noted that, in any of the above forms, the most important purpose is to describe the information of the system, the user, and the service type corresponding to the data, where the standard and the service type can be encapsulated. Therefore, the data of different systems or different services can be differentiated by the scope of the encapsulated data, and can also be distinguished by adding an identifier, and the data corresponding to different users is only differentiated by adding an identifier, and the specific application Which of the above forms can be adjusted according to actual needs, such changes do not affect the scope of protection of the present invention.
进一步的, 上述的封装过程根据实施主体的差异, 本步骤中所接收到的数 据具体可以分为以下两种情况: Further, the foregoing encapsulation process may be classified into the following two cases according to differences in implementation entities: the data received in this step may be specifically:
所述回程网络发送的由所述回程网络的基站进行封装的一种或多种制式 的数据; 或, Data of one or more standards encapsulated by the base station of the backhaul network and sent by the backhaul network; or
所述回程网络发送的由所述回程网络的网关节点进行封装的一种或多种 制式的数据。 One or more types of data encapsulated by the gateway node of the backhaul network sent by the backhaul network.
具体实施主体的选择差异不会影响本发明的保护范围。 The difference in the choice of the specific implementation subject does not affect the scope of protection of the present invention.
步骤 S302、 对所述封装后的一种或多种制式的数据进行解封装处理。 在具体的实施场景中, 本步骤中所进行的解封装处理的内容根据具体*** 中接入点的功能设定, 具体可以分为以下两种情况: Step S302: Perform decapsulation processing on the encapsulated data of one or more standards. In a specific implementation scenario, the content of the decapsulation process performed in this step is set according to the function of the access point in the specific system, and may be specifically classified into the following two cases:
情况一、 当所述接入点只实现 RRU ( Radio Remote Unit, 射频处理单元 ) 的功能时, 对所述封装后的一种或多种制式的数据进行完全解封装处理。 Case 1: When the access point only implements the function of the RRU (Radio Remote Unit), the encapsulated one or more types of data are completely decapsulated.
情况二、 当所述接入点同时实现 RRU和的功能时, 将所述封装后的一种 或多种制式的数据进行制式解析处理。 Case 2: When the access point simultaneously implements the function of the RRU, the encapsulated one or more types of data are subjected to standard parsing processing.
步骤 S303、 将解封装后的一种或多种制式的数据发送给相应制式的接入 点, 以使所述相应制式的接入点将数据转发给终端设备。 Step S303: Send the decapsulated data of one or more standards to the access point of the corresponding system, so that the access point of the corresponding standard forwards the data to the terminal device.
与步骤 S303 中的两种情况相对应, 本步骤中将数据发送给接入点后, 接 入点中的处理过程同样包括两种情况: Corresponding to the two cases in step S303, after the data is sent to the access point in this step, the processing in the access point also includes two cases:
情况一、 当所述接入点只实现 RRU的功能时, 所述接入点直接将完全解 封装处理后的数据发送给相应的终端设备。 Case 1: When the access point only implements the function of the RRU, the access point directly sends the completely decapsulated data to the corresponding terminal device.
情况二、 当所述接入点同时实现 RRU和 BBU ( Base band Unit, 基带处理
单元)的功能时, 所述接入点将制式解析处理后的数据进行业务解析处理和用 户解析处理, 并将完成业务解析处理和用户解析处理的数据发送给相应的终端 设备。 Case 2: When the access point implements both RRU and BBU (Base Band Unit) In the function of the unit, the access point performs the service analysis processing and the user analysis processing on the data after the system analysis processing, and transmits the data that completes the service analysis processing and the user analysis processing to the corresponding terminal device.
上述的过程说明了数据由回程网络发送至接入点的下行方向上的处理方 式, 在实际应用中, 对于接入点发送到回程网络的上行方向的处理流程同样可 以基于类似的处理思路来实现, 如图 4所示, 具体的处理流程说明如下: 步骤 S401、 接收一种或多种制式的接入点发送的数据。 The foregoing process illustrates the processing manner in which the data is sent from the backhaul network to the access point in the downlink direction. In an actual application, the processing procedure for the uplink direction that the access point sends to the backhaul network can also be implemented based on a similar processing concept. As shown in FIG. 4, the specific processing flow is as follows: Step S401: Receive data sent by an access point of one or more standards.
在本步骤中, 对应接入点的具体功能设置, 所接收到的数据分为以下两种 情况: In this step, corresponding to the specific function settings of the access point, the received data is divided into the following two cases:
情况一、 当所述接入点只实现 RRU的功能时, 接收所述一种或多种制式 的接入点发送的未经封装处理的相应制式的数据。 Case 1: When the access point only implements the function of the RRU, the data of the corresponding standard of the unencapsulated processing sent by the access point of the one or more standards is received.
情况二、 当所述接入点同时实现 RRU和 BBU的功能时, 接收所述一种或 多种制式的接入点发送的完成业务信息封装处理和用户信息封装处理的相应 制式的数据。 Case 2: When the access point implements the functions of the RRU and the BBU at the same time, receiving the data of the corresponding system for completing the service information encapsulation process and the user information encapsulation process sent by the access point of the one or more standards.
步骤 S402、 将接收到的数据进行统一封装。 Step S402: Perform unified encapsulation on the received data.
与步骤 S401 中的两种情况相对应, 本步骤中接收到数据后, 具体的数据 处理过程同样包括两种情况: Corresponding to the two cases in step S401, after receiving data in this step, the specific data processing process also includes two cases:
情况一、 当所述接入点只实现 RRU的功能时, 将接收到的数据进行统一 的完全封装。 Case 1: When the access point only implements the function of the RRU, the received data is uniformly encapsulated completely.
情况二、 当所述接入点同时实现 RRU和 BBU的功能时, 将接收到的完成 业务信息封装处理和用户信息封装处理的相应制式的数据进行统一的制式封 装处理。 Case 2: When the access point implements the functions of the RRU and the BBU at the same time, the received data of the corresponding service information encapsulation processing and the user information encapsulation processing are unified and sealed.
步骤 S403、将统一封装后的数据发送给所述回程网络, 以使所述回程网络 将所述统一封装后的数据解封装为不同制式的数据, 并发送给相应制式的网络 设备。
进一步的, 上述的解封装过程根据实施主体的差异, 本步骤中将数据发送 所述回程网络的基站将所述统一封装后的数据解封装为不同制式的数据, 并发送给相应制式的网络设备; 或, Step S403: Send the uniformly encapsulated data to the backhaul network, so that the backhaul network decapsulates the uniformly encapsulated data into data of different standards, and sends the data to a network device of a corresponding standard. Further, the decapsulation process is performed according to the difference of the implementation body. In this step, the base station that sends data to the backhaul network decapsulates the uniformly encapsulated data into data of different standards, and sends the data to a network device of a corresponding standard. ; or,
所述回程网络的网关节点将所述统一封装后的数据解封装为不同制式的 数据, 并发送给相应制式的网络设备。 The gateway node of the backhaul network decapsulates the uniformly encapsulated data into data of different standards and sends the data to a network device of a corresponding standard.
在实际的应用场景中, 上述的封装和解封装的处理方式也可以通过建立相 应的承载信道的方式进行代替, 从而, 同样可以实现上述的技术流程, 由于承 载信道本身的区分功能, 不再需要上述的封装和解封装处理流程, 但均属于为 了区分不同的制式或业务的数据而采取的技术手段, 这样的变化并不影响本发 明的保护范围。 In the actual application scenario, the above-mentioned processing method of encapsulation and decapsulation can also be replaced by establishing a corresponding bearer channel, so that the above technical process can also be implemented, and the above-mentioned different functions of the bearer channel itself are no longer needed. The encapsulation and decapsulation process flows, but all belong to the technical means adopted to distinguish data of different standards or services, and such changes do not affect the scope of protection of the present invention.
与现有技术相比, 本发明实施例具有以下优点: Compared with the prior art, the embodiment of the invention has the following advantages:

下面,结合具体的应用场景,对本发明实施例所提出的技术方案进行说明。 本发明实施例以如图 2所示的车载***覆盖方式中的总体架构为基础, 对 其中的车载处理模块的结构提出了具体的设计方案, 并基于此结构提出了相应 的技术处理流程, 实现高速移动场景中的数据传输解决方案。 The technical solutions proposed in the embodiments of the present invention are described below in conjunction with specific application scenarios.

下面以 LTE制式的 AP为例进行说明。 The following takes an LTE AP as an example.
在 LTE***中, 基站设备 ( eNB )通常由两个核心处理单元构成, 分别为 基带处理单元和射频处理单元。 其中 BBU的主要功能是实现数据的封装、 调 度、 调制解调以及编解码等功能, 而 RRU的主要功能是通过天线完成射频信 号的收发。 BBU与 RRU之间通过 Ir接口进行数据与信息交互。 综合考虑 IFU 功能与 LTE AP功能划分时, 有两种基本的实现方案, 如图 6所示。 In an LTE system, a base station device (eNB) is usually composed of two core processing units, which are a baseband processing unit and a radio frequency processing unit, respectively. The main function of the BBU is to implement data encapsulation, scheduling, modulation and demodulation, and codec. The main function of the RRU is to transmit and receive RF signals through the antenna. Data and information exchange between the BBU and the RRU through the Ir interface. When considering the IFU function and LTE AP function partitioning, there are two basic implementation schemes, as shown in Figure 6.
在方案 1中, AP只实现 RRU功能, BBU功能由车载处理模块的 IFU实 现, AP与 IFU之间通过 Ir接口进行通信。 In scheme 1, the AP only implements the RRU function. The BBU function is implemented by the IFU of the in-vehicle processing module, and the AP and the IFU communicate through the Ir interface.
在方案 2中, AP同时实现 BBU和 RRU的功能, 而车载处理模块的 IFU 实现 X2接口的协议功能, AP通过 X2接口与 IFU进行通信。 In scheme 2, the AP implements the functions of the BBU and the RRU at the same time, and the IFU of the in-vehicle processing module implements the protocol function of the X2 interface, and the AP communicates with the IFU through the X2 interface.
两种方案下的各模块的功能划分如表 1所示。 The function division of each module under the two schemes is shown in Table 1.

User-level data encapsulation and decapsulation, data encoding and decoding, and data transmission and reception. In the foregoing solution 2, the communication between the IFU and the AP by using the X2 interface is only a possible way, and other standard interfaces or new interface standards may be used.
如图 7所示, 为本发明实施例提出的一种高速移动通信的实现方法的流程 示意图, 该方法具体包括以下步骤: FIG. 7 is a schematic flowchart of a method for implementing high-speed mobile communication according to an embodiment of the present invention, where the method specifically includes the following steps:
步骤 S701、 回程网对来自外部网络(各种制式对应的核心网)的数据进行 封装处理。 Step S701: The backhaul network encapsulates data from an external network (the core network corresponding to various standards).
其中, 封装的方法包括如步骤 S301中的多种方式, 主要有以下几种: The method of encapsulation includes multiple methods as in step S301, and the main ones are as follows:
( 1 )将各种制式的数据分别进行封装, 并分别添加用户标识和业务标识, 区分不同用户的不用业务。 (1) Encapsulate data of various standards separately, and add user identification and service identification respectively to distinguish different services of different users.
( 2 )将不同制式的数据统一封装, 并添加制式标识、 用户标识和业务标
识, 区分不同制式下各用户的业务。 (2) uniformly encapsulate data of different standards, and add standard identification, user identification and business standard Knowledge, distinguish the business of each user under different standards.
( 3 )根据业务类型进行封装, 并添加制式标识和用户标识, 区分不同制 式下的不同用户 (3) Encapsulation according to the type of service, adding a standard identifier and a user identifier to distinguish different users in different formats
数据封装的功能可以通过回程网的基站设备完成, 也可以添加网关节点专 门负责数据的封装与解封装功能。 The function of data encapsulation can be completed by the base station equipment of the backhaul network, and the gateway node can be added to be responsible for the encapsulation and decapsulation functions of data.
完成数据封装之后, 回程网将数据发送到车载处理模块。 After the data is encapsulated, the backhaul network sends the data to the in-vehicle processing module.
步骤 S702、车载处理模块的 E-UE负责接收回程网发送的数据, DPU对数 据进行解封装, 并通过 IFU模块将数据发送到相应的 AP。 Step S702: The E-UE of the in-vehicle processing module is responsible for receiving data sent by the backhaul network, and the DPU decapsulates the data, and sends the data to the corresponding AP through the IFU module.
需要指出的是, IFU实现的功能不同, 数据下发到 AP的方式也不同, 仍 以上述 LTE AP制式为例, 如果 AP只实现的 RRU功能, 那么 DPU将对数据 进行完全解封装, 并将各用户的业务数据分别发送到 AP, AP直接发送到终端 而不必再进行处理;如果 AP同时实现了 BBU和 RRU功能,那么 DPU只需将 LTE制式的数据解析出来, 而不必对深层的用户 /业务信息进行解析, 将数据发 送到 AP之后, 由 AP完成用户和业务级的解析并将数据发送到对应的用户。 It should be noted that the functions implemented by the IFU are different, and the manner in which the data is sent to the AP is different. The above LTE AP standard is still taken as an example. If the AP only implements the RRU function, the DPU will completely decapsulate the data, and The service data of each user is sent to the AP, and the AP sends the data directly to the terminal without further processing. If the AP implements the BBU and RRU functions at the same time, the DPU only needs to parse the data of the LTE system without having to go to the deep user/ After the service information is parsed, after the data is sent to the AP, the AP completes the user and service level resolution and sends the data to the corresponding user.
步骤 S703、 各 AP将接收到的数据发送到用户。 Step S703: Each AP sends the received data to the user.
相应的, 上行数据发送过程也分为三个步骤, 如下所述。 Correspondingly, the uplink data transmission process is also divided into three steps, as described below.
步骤 S704、 各制式的 AP将接收的上行数据发送到车载处理模块。 Step S704: Each AP of the standard system sends the received uplink data to the in-vehicle processing module.
在这一步骤中, 如果 AP只实现 RRU功能, 则不对数据进行额外处理, 只 负责接收和转发; 如果 AP同时实现了 RRU功能, 则同时完成用户和业务级数 据的封装, 将封装之后的数据发送到车载处理模块。 In this step, if the AP only implements the RRU function, it does not perform additional processing on the data, and is only responsible for receiving and forwarding. If the AP implements the RRU function at the same time, the user and service level data are encapsulated at the same time, and the encapsulated data is encapsulated. Send to the onboard processing module.
步骤 S705、 车载处理模块的 DPU负责对接收到的各种制式的用户数据进 行统一封装,封装的方式与下行数据接收流程中的步骤二类似。完成封装之后, 通过 E-UE将数据发送到回程网。 Step S705: The DPU of the in-vehicle processing module is responsible for uniformly encapsulating user data of various standards received, and the encapsulation manner is similar to step 2 in the downlink data receiving process. After the encapsulation is completed, the data is sent to the backhaul network through the E-UE.
步骤 S706、 回程网将接收到的数据进行解封装,将将各制式的数据发送到 对应的核心网节点。
需要指出的是, 数据封装与解封装过程是节点间进行数据通信的一种可能 方式, 另外一种常见的方式是建立承载通道, 通道本身具有标识作用, 而不必 在数据包中添加额外的标识, 但其本质与在数据包中直接添加标识并无差异, 这样的变化并不影响本发明的保护范围。 Step S706: The backhaul network decapsulates the received data, and sends data of each standard to the corresponding core network node. It should be pointed out that the data encapsulation and decapsulation process is a possible way for data communication between nodes. Another common way is to establish a bearer channel, and the channel itself has an identification function without adding an additional identifier to the data packet. However, the essence is not different from the direct addition of the identifier in the data packet, and such a change does not affect the scope of protection of the present invention.
