技术领域technical field
本申请涉及无线通信技术领域，尤其涉及一种通信方法和装置。The present application relates to the field of wireless communication technologies, and in particular, to a communication method and apparatus.
背景技术Background technique
目前，工业园区对定位服务的需求较大，很多设备都需要有一定的定位能力才能够完成自动作业等功能。如无人搬运车(automatic guided vehicle，AGV)等设备。当前的定位技术可以包括全球定位***(global position system，GPS)、北斗定位***、惯性导航以及电磁导航等多种定位技术。不仅如此，工业园区还可以借助网络设备提供的定位服务来实现工业园区的定位服务。At present, industrial parks have a large demand for positioning services, and many devices need to have certain positioning capabilities to complete functions such as automatic operations. Such as automatic guided vehicle (AGV) and other equipment. The current positioning technology can include various positioning technologies such as global positioning system (GPS), Beidou positioning system, inertial navigation and electromagnetic navigation. Not only that, the industrial park can also realize the location service of the industrial park with the help of the location service provided by the network equipment.
因此，工业园区可以部署独立私网实现定位服务。所谓独立组网的非公共网络(standalone non-public network，SNPN)，不依赖于公共陆地移动网络(public land mobile network，PLMN)，由SNPN专属运营商运营。独立私网当中的网元设备都服务于该私网的用户设备(user equipment，UE)。SNPN内的控制面信令和用户面数据均不会传输至外部网络，达到一定的安全隐私效果。Therefore, industrial parks can deploy independent private networks to implement location services. The so-called standalone non-public network (SNPN) does not depend on the public land mobile network (PLMN), and is operated by the SNPN exclusive operator. The network element devices in the independent private network all serve the user equipment (UE) of the private network. The control plane signaling and user plane data in the SNPN will not be transmitted to the external network, achieving a certain security and privacy effect.
若要在SNPN架构中提供定位服务，则需要部署与定位服务相关的网元，如移动网关位置中心(gateway mobile location centre，GMLC)和位置管理功能(location management function，LMF)等网元。然而，部署这些定位服务相关的网元无疑会增加建设成本以及运维复杂度。To provide location services in the SNPN architecture, it is necessary to deploy network elements related to location services, such as mobile gateway location center (gateway mobile location center, GMLC) and location management function (location management function, LMF) and other network elements. However, deploying these network elements related to location services will undoubtedly increase construction costs and O&M complexity.
发明内容SUMMARY OF THE INVENTION
本申请提供一种通信方法和装置，用于减少建设成本和运维复杂度。The present application provides a communication method and device for reducing construction cost and operation and maintenance complexity.
第一方面，本申请实施例提供一种通信方法。该方法可以由第一网络的第一网络开放功能网元执行。该方法中，第一网络开放功能网元可以接收用于请求终端设备的位置信息的位置请求消息。该终端设备可以位于第一网络。第一网络开放功能网元可以向第二网络的第二网络开放功能网元发送第一请求消息。这里的第一网络和第二网络可以不同。该第一请求消息可以包含第一网络的标识，该第一请求消息可以用于请求所述第二网络确定所述终端设备的位置信息。该第一网络开放功能网元还可以接收第二网络开放功能网元发送的所述终端设备的位置信息。第一网络开放功能网元还可以将该终端设备的位置信息携带在与所述位置请求消息对应的位置请求响应中，并发送该位置请求响应。In a first aspect, an embodiment of the present application provides a communication method. The method may be performed by a first network open function network element of the first network. In this method, the first network opening function network element may receive a location request message for requesting location information of the terminal device. The terminal device may be located in the first network. The first network opening function network element may send the first request message to the second network opening function network element of the second network. The first network and the second network here may be different. The first request message may contain an identifier of the first network, and the first request message may be used to request the second network to determine the location information of the terminal device. The first network opening function network element may also receive the location information of the terminal device sent by the second network opening function network element. The first network opening function network element may further carry the location information of the terminal device in the location request response corresponding to the location request message, and send the location request response.
基于该方案，第一网络中可以无需部署定位服务相关的网元，在有定位需求时可以向第二网络发送第一请求消息，请求第二网络提供定位服务。第一网络可以接收第二网络发 送的位置信息，实现对终端设备的定位，可以节省建设和运维成本，也可以降低运维复杂度。Based on this solution, network elements related to positioning services may not be deployed in the first network, and when there is a positioning requirement, a first request message may be sent to the second network to request the second network to provide positioning services. The first network can receive the location information sent by the second network to realize the positioning of the terminal equipment, which can save construction and operation and maintenance costs, and can also reduce the complexity of operation and maintenance.
在一种可能的实现方式中，第一网络开放功能网元接收了所述位置请求消息之后，还可以根据所述位置请求消息生成第一事务号。该第一事务号用于标识终端设备的服务请求。第一网络开放功能可以在第一请求消息中携带第一网络的标识和所述第一事务号。In a possible implementation manner, after receiving the location request message, the first network opening function network element may further generate a first transaction number according to the location request message. The first transaction number is used to identify the service request of the terminal device. The first network opening function may carry the identifier of the first network and the first transaction number in the first request message.
基于该方案，可以用第一事务号标识终端设备的服务请求，将第一事务号和第一网络的标识携带在第一请求消息中发送给第二网络开放功能网元，可以对终端设备有一定的安全隐私保护效果。Based on this solution, the first transaction number can be used to identify the service request of the terminal device, and the first transaction number and the identifier of the first network can be carried in the first request message and sent to the second network open function network element. Certain security and privacy protection effects.
在一种可能的实现方式中，该第一请求消息中还可以包含第一信息；该第一信息用于标识所述终端设备，该第一信息不同于终端设备在第一网络中的标识。其中，第一信息可以包括终端设备的第一标识和第一指示中的至少一个。其中，第一标识可以是终端设备在第一网络的通用标识。这里的通用标识可以是所有第一网络中的终端设备通用的标识，或者还可以是第一网络中的部分终端设备通用的标识。例如，第一网络中的每一个终端设备的通用标识可以相同也可以不相同。该第一指示可以用于指示第一标识为第一网络中的终端设备的标识或第一指示可以指示该终端设备为非第二网络的终端设备。In a possible implementation manner, the first request message may further include first information; the first information is used to identify the terminal device, and the first information is different from the identification of the terminal device in the first network. The first information may include at least one of a first identifier and a first indication of the terminal device. The first identifier may be a general identifier of the terminal device in the first network. The universal identifier here may be an identifier common to all terminal devices in the first network, or may also be an identifier common to some terminal devices in the first network. For example, the universal identifiers of each terminal device in the first network may be the same or different. The first indication may be used to indicate that the first identification is an identification of a terminal device in the first network or the first indication may indicate that the terminal device is not a terminal device of the second network.
基于该方案，第一网络开放功能网元可以用第一信息标识第一网络的终端设备，使得第二网络可以得知该终端设备是非第二网络的终端设备，但由于第二网络无法获知终端设备在第一网络中的标识，因此可以保护终端设备的隐私，提高第一网络的安全性。Based on this solution, the first network opening function network element can use the first information to identify the terminal device of the first network, so that the second network can know that the terminal device is not a terminal device of the second network, but because the second network cannot know the terminal device The identification of the device in the first network can therefore protect the privacy of the terminal device and improve the security of the first network.
在一种可能实现的方式中，该第一信息可以是设置值。例如，该第一信息中的第一标识可以是设置值，其中第一网络中的所有终端设备的第一标识相同。或者，不同的终端设备的第一信息可以不同。例如，可以为每一个第一网络的终端设备分配一个不同的标识，该标识用于第二网络识别该终端设备为第一网络的终端设备，而无法使第二网络识别终端设备的身份。或者，该第一信息可以包含第一网络的标识，且不同的终端设备的第一信息不同。例如，该第一标识中可以包括第一网络的标识。此时，该第一标识可以包含第一指示的作用，即该第一标识可以指示该第一标识为第一网络中的终端设备的标识，第二网络可以通过第一标识确定该终端设备为第一网络的标识，但是第二网络无法通过该第一标识识别终端设备的身份，由此隐式地包含了第一指示的作用。In a possible implementation manner, the first information may be a setting value. For example, the first identifier in the first information may be a setting value, wherein the first identifiers of all terminal devices in the first network are the same. Alternatively, the first information of different terminal devices may be different. For example, each terminal device of the first network can be assigned a different identifier, and the identifier is used by the second network to identify the terminal device as a terminal device of the first network, but cannot enable the second network to identify the identity of the terminal device. Alternatively, the first information may include an identifier of the first network, and the first information of different terminal devices is different. For example, the first identifier may include the identifier of the first network. At this time, the first identifier may include the function of the first indication, that is, the first identifier may indicate that the first identifier is the identifier of the terminal device in the first network, and the second network may determine that the terminal device is the terminal device in the first network through the first identifier. The identifier of the first network, but the second network cannot identify the identity of the terminal device through the first identifier, thus implicitly including the role of the first indication.
基于该方案，可以为第一网络中的所有终端设备分配相同的第一信息，还可以为第一网络中的每一个终端设备分配一个第一信息，该第一信息中还可以包含第一网络的标识，这样可以使得第二网络根据该第一信息识别到该终端设备是第一网络中的终端设备，而无法根据该第一信息识别到终端设备的身份，可以保护终端设备的隐私，可以提高第一网络的安全性。Based on this solution, the same first information can be allocated to all terminal devices in the first network, and each terminal device in the first network can also be allocated a piece of first information, and the first information can also include the first network In this way, the second network can recognize that the terminal device is a terminal device in the first network according to the first information, but cannot identify the identity of the terminal device according to the first information, which can protect the privacy of the terminal device, and can Improve the security of the first network.
在一种可能的实现方式中，第一网络开放功能网元可以从第二网络开放功能网元接收第一请求消息的第一响应消息。该第一响应消息可以包含终端设备的位置信息。第一网络开放功能网元则可以根据第一网络的标识、第一事务号和第二事务号和第一信息中的至少一个，确定终端设备在第一网络中的标识。这里的第二事务号可以用于标识第一网络的服务请求。第一网络开放功能网元可以根据所述终端设备在第一网络中的标识，发送位置响应消息。这里的位置响应消息可以包含所述终端设备的位置信息。In a possible implementation manner, the first network opening function network element may receive the first response message of the first request message from the second network opening function network element. The first response message may contain location information of the terminal device. The first network open function network element may determine the identification of the terminal device in the first network according to at least one of the identification of the first network, the first transaction number and the second transaction number, and the first information. The second transaction number here may be used to identify the service request of the first network. The first network opening function network element may send a location response message according to the identification of the terminal device in the first network. The location response message here may contain location information of the terminal device.
基于该方案，第二网络开放功能网元可以通过第二事务号标识第一网络的服务请求，第一网络开放功能网元与第二网络开放功能网元可以通过第一网络的标识、第一事务号和 第二事务号和第一信息通信，可以提高第一网络的安全性，保护终端设备的隐私。Based on this solution, the second network open function network element can identify the service request of the first network through the second transaction number, and the first network open function network element and the second network open function network element can use the identification of the first network, the first network open function network element The transaction number and the second transaction number communicate with the first information, which can improve the security of the first network and protect the privacy of the terminal device.
在一种可能的实现方式中，第一网络开放功能网元在向第二网络开放功能网元发送第一请求消息之后，还可以接收第二网络开放功能网元发送的第二数据请求消息。该第二数据请求消息可以包括第一事务号、第一网络的标识、第二事务号和所述第一信息中的至少一个。该第二数据请求消息可以用于请求获取定位所需的数据。第一网络开放功能网元可以向第二网络开放功能网元发送第二响应消息。该第二响应消息可以包括所述收集到的定位所需的数据。In a possible implementation manner, after sending the first request message to the second network opening function network element, the first network opening function network element may also receive a second data request message sent by the second network opening function network element. The second data request message may include at least one of a first transaction number, an identification of the first network, a second transaction number, and the first information. The second data request message may be used to request to obtain data required for positioning. The first network opening function network element may send the second response message to the second network opening function network element. The second response message may include the collected data required for positioning.
基于该方案，第一网络开放功能网元可以根据第一事务号、第一网络的标识、第二事务号和第一信息中的至少一个，确定终端设备在第一网络中的标识，从而收集该终端设备的定位所需的数据，并将收集到的数据发送给第二网络开放功能网元实现对终端设备的定位，因此第一网络中无需部署定位服务相关的网元，可以节省建设和运维成本，降低运维复杂度。Based on this solution, the network element of the first network opening function can determine the identifier of the terminal device in the first network according to at least one of the first transaction number, the identifier of the first network, the second transaction number, and the first information, thereby collecting the identifier of the terminal device in the first network. The data required for the positioning of the terminal equipment is sent to the second network open function network element to realize the positioning of the terminal equipment.

In daily life, it is generally the public network that provides network services for terminal devices. The public network, namely the public land mobile network (PLMN), is a network established and operated by the government or its approved operators for the purpose of providing land mobile communication services to the public. This network is usually interconnected with the public switched telephone network (PSTN) to form a communications network on a regional or national scale.
2)私网，除了公网，出于某些目的，运营商或者私人也会搭建一些私网(non-public networks，NPN)来满足用户的需求。私网也可以被称作非公网络，是指对特定用户开放的网络，例如公司、学校或者工厂搭建的内部网络。未与私网签约的终端设备不允许接入私网。2) Private network, in addition to the public network, for some purposes, operators or private individuals will also build some private networks (non-public networks, NPN) to meet the needs of users. A private network can also be called a non-public network, which refers to a network open to specific users, such as an internal network built by a company, school, or factory. Terminal devices that are not subscribed to the private network are not allowed to access the private network.
3)本申请实施例中的术语“***”和“网络”可被互换使用。“多个”是指两个或两个以上，其它量词与之类似。“和/或”描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。此外，对于单数形式“a”，“an”和“the”出现的元素(element)，除非上下文另有明确规定，否则其不意味着“一个或仅一个”，而是意味着“一个或多于一个”。例如，“a device”意味着对一个或多个这样的device。再者，至少一个(at least one of).......”意味着后续关联对象中的一个或任意组合，例如“A，B和C中的至少一个”包括A，B，C，AB，AC，BC，或ABC。3) The terms "system" and "network" in the embodiments of this application may be used interchangeably.
