具体实施方式Detailed ways

参见图1，UE通过与近距发现功能的交互以及发送无线广播信令以及监听来自其他终端的无线广播信令，从而实现相互近距发现，具体流程如下：Referring to Figure 1, the UE realizes mutual short-range discovery by interacting with the short-range discovery function, sending wireless broadcast signaling, and monitoring wireless broadcast signaling from other terminals. The specific process is as follows:

步骤101：UE-A(例如通过无线空口的用户面承载及核心网用户面承载)向近距发现功能(ProSe Function)发送发现请求(Discovery Request)。Step 101: UE-A sends a discovery request (Discovery Request) to the ProSe Function (for example, through the user plane bearer of the wireless air interface and the core network user plane bearer).

比如：发送Discovery Request中可以携带应用信息、用户标识、模式信息、以及角色信息中的一项或多项。For example, sending a Discovery Request may carry one or more of application information, user ID, mode information, and role information.

其中，应用信息标识应用，应用信息包含3GPP网络用于标识具体应用的标识信息(Application ID)，应用信息可能还可以包含3GPP网络用于路由数据给应用服务器的近距应用标识信息(ProSe App ID)。The application information identifies the application, the application information includes the identification information (Application ID) used by the 3GPP network to identify the specific application, and the application information may also include the proximity application identification information (ProSe App ID) used by the 3GPP network to route data to the application server. ).

用户标识为3GPP网络用于标识用户的信息，比如：国际移动终端标识(International Mobile Station Identifier，IMSI)。The user identifier is information used by the 3GPP network to identify the user, such as: International Mobile Station Identifier (IMSI).

模式信息标识发现方式，例如模式A(Model A)为监听方向近距发现功能发送匹配报告；模式B(Model B)为监听方收到其他终端广播的直接通讯请求，向对方返回响应，并由对方向近距发现功能发送匹配报告。The mode information identifies the discovery method. For example, mode A (Model A) sends a matching report to the short-range discovery function in the listening direction; mode B (Model B) is for the listening party to receive a direct communication request broadcast by other terminals, and return a response to the other party. Send a match report to the Proximity Discovery feature.

角色信息标识终端为广播发送方还是广播监听方。The role information identifies whether the terminal is a broadcast sender or a broadcast listener.

步骤102：ProSe Function接收到UE-A的发现请求，依据用户标识向UE-A的签约服务器(Home Subscriber Server，HSS)请求授权，HSS判断UE-A签约了近距发现业务，返回允许执行近距发现操作的指示。Step 102: The ProSe Function receives the discovery request from UE-A, and requests authorization from the Home Subscriber Server (HSS) of UE-A according to the user identity. Instructions from the discovery operation.

步骤103：ProSe Function向应用服务器(App Server)请求授权，App Server返回允许执行近距发现操作的指示。Step 103: The ProSe Function requests authorization from an application server (App Server), and the App Server returns an instruction to allow the proximity discovery operation to be performed.

步骤103为可选步骤。Step 103 is an optional step.

步骤104：ProSe Function向UE-A发送发现响应(Discovery Response)。Step 104: The ProSe Function sends a discovery response (Discovery Response) to UE-A.

比如，Discovery Response通过核心网用户面承载以及无线空口的用户面承载发送到UE-A，Discovery Response消息携带发现码信息。For example, the Discovery Response is sent to the UE-A through the core network user plane bearer and the user plane bearer of the wireless air interface, and the Discovery Response message carries the discovery code information.

如果UE-A为广播发送方，发现码信息可以包含应用码(App Code)，进一步地，发现码信息还可以包含响应码过滤器(Response Code Filter)。If UE-A is the broadcast sender, the discovery code information may include an application code (App Code), and further, the discovery code information may also include a response code filter (Response Code Filter).

如果UE-A为广播监听方，发现码信息可以包含应用码过滤器(App Code Filter)，进一步地，发现码信息还可以包含响应码(Response Code)。If UE-A is the broadcast listener, the discovery code information may include an application code filter (App Code Filter), and further, the discovery code information may also include a response code (Response Code).

步骤105：UE-B也执行上述步骤101～104的操作。Step 105: UE-B also performs the operations of the above steps 101-104.

此例中，设UE-A为广播发送方，UE-B为广播监听方。In this example, it is assumed that UE-A is the broadcast sender and UE-B is the broadcast listener.

步骤106：UE-A通过无线空口广播直接通讯请求(Direct CommunicationRequest)消息。Step 106: UE-A broadcasts a direct communication request (Direct CommunicationRequest) message through the wireless air interface.

比如，发送Direct Communication Request消息，携带用户信息和应用码，其中用户信息包含连接层用户标识(Layer-2ID)，Layer-2ID用于对端UE通过无线空口向本UE发送消息，应用层用户信息。For example, a Direct Communication Request message is sent, carrying user information and application code, where the user information includes the connection layer user identifier (Layer-2ID). .

步骤107：如果UE-A和UE-B都采用Model B，则UE-B通过无线空口向UE-A返回直接通讯响应，比如发送Direct Communication Response，携带用户信息和响应码。Step 107: If both UE-A and UE-B use Model B, UE-B returns a direct communication response to UE-A through the wireless air interface, such as sending a Direct Communication Response, carrying user information and a response code.

步骤107为可选步骤。Step 107 is an optional step.

步骤108：如果UE-A和UE-B都采用Model B，则UE-A通过无线空口的用户面承载及核心网用户面承载向近距发现功能(ProSe Function)发送匹配请求，比如发送匹配报告(Match Report)消息，Match Report消息携带应用信息和响应码；Step 108: If both UE-A and UE-B use Model B, UE-A sends a matching request to the ProSe Function through the user plane bearer of the wireless air interface and the core network user plane bearer, such as sending a matching report (Match Report) message, the Match Report message carries application information and response code;

如果UE-A和UE-B都采用Model A，则UE-B通过无线空口的用户面承载及核心网用户面承载向近距发现功能(ProSe Function)发送匹配请求，携带应用信息和应用码。If both UE-A and UE-B use Model A, UE-B sends a matching request to the ProSe Function through the user plane bearer of the wireless air interface and the core network user plane bearer, carrying application information and application code.

UE上的近距功能如果收到了App Code Filter，可以在监听到来自其他终端携带App Code的广播消息时，判断App Code是否在App Code Filter中，如果在则处理该广播消息，否则丢弃。If the proximity function on the UE receives the App Code Filter, it can judge whether the App Code is in the App Code Filter when listening to the broadcast message carrying the App Code from other terminals, and if so, process the broadcast message, otherwise discard it.

UE上的近距功能如果收到了Response Code Filter，在发出携带App Code和接收地址的广播消息后，可以在监听到来自其他终端发往接收地址的携带Response Code的消息时，判断Response Code是否在Response Code Filter中，如果在则处理该消息，否则丢弃。If the proximity function on the UE receives the Response Code Filter, after sending out the broadcast message carrying the App Code and the receiving address, it can judge whether the Response Code is within the In the Response Code Filter, if it exists, process the message, otherwise discard it.

步骤604：应用服务器向网络能力开放功能(Network Exposure Function，NEF)发送启动近距通讯服务请求。Step 604: The application server sends a request for starting the near field communication service to the Network Exposure Function (NEF).

NEF也可以只判断是否允许用户使用近距通讯服务，或NEF只判断是否允许用户针对相应应用使用近距通讯服务，或NEF只判断是否允许用户在相应服务网络中使用近距通讯服务。The NEF may also only judge whether to allow the user to use the NFC service, or the NEF only to judge whether to allow the user to use the NFC service for the corresponding application, or the NEF only to judge whether to allow the user to use the NFC service in the corresponding service network.

For example, the application ID received by the NEF is a globally unique ID, and the unified data management function returns a unique ID within the scope of the mobile network.

步骤606：NEF调用统一数据管理的参数创建或更新过程，此处的交互可以是与UDM交互，也可以是与UDR交互。Step 606: The NEF invokes the parameter creation or update process of the unified data management, and the interaction here may be the interaction with the UDM or the interaction with the UDR.
