配置方法和装置 Configuration method and device

技术领域 Technical field

本发明实施例涉及通信技术领域，尤其涉及一种配置方法和装置。 The embodiments of the present invention relate to the field of communications technologies, and in particular, to a configuration method and apparatus.

背景技术 Background technique

治安出警、火灾救援、医疗急救等社会公共安全服务时的通信，会遇到窃听、冒充消息发送人、恶意删除、篡改消息内容等安全因素和由于信号占线造成的时间损失。地震、海啸等场景下，设备损坏造成没有网络覆盖，因此，上述的公共安全场景中的通信，无论是否有网络覆盖，都需要在专门的通信网络下进行。目前，一种长期演进（Long Term Evolution, 简称： LTE) 的增强技术，称为近距离服务（Proximity-based Service, 简称： ProSe) ，可以满足公共安全通信的需求， ProSe 支持下的公共安全通信（ProSe Public Safety通信）允许用户设备（User Equipment, 简称： UE)处于无网络覆盖时，可以不经过网络设备而是直接与对方传输信息。当有网络覆盖时， UE在进行 ProSe Public Safety通信之前， UE的归属网络需要为 UE进行授权以及配置通信参数。 When public security, fire rescue, medical emergency, and other social public safety services communicate, it will encounter security factors such as eavesdropping, pretending to be a sender, malicious deletion, tampering with message content, and time loss due to signal busy. In the earthquake, tsunami, etc., the equipment is damaged and there is no network coverage. Therefore, the communication in the above public security scenario, whether or not there is network coverage, needs to be carried out under a special communication network. At present, an enhanced technology of Long Term Evolution (LTE), called Proximity-based Service (ProSe), can meet the needs of public safety communication, and public safety communication supported by ProSe. (ProSe Public Safety communication) allows user equipment (User Equipment, UE for short) to transmit information directly to the other party without going through the network equipment when there is no network coverage. When there is network coverage, the UE's home network needs to authorize the UE and configure communication parameters before performing ProSe Public Safety communication.

当 UE漫游至拜访地网络时， UE向拜访地网络近距离服务发现和通信控制 ( Visited Proximity-based Service Discovery and Communication control Functionality, 简称： V-PDCF) 网元注册请求， V-PDCF从归属地网络近距离月艮务发现禾口通信控制 ( Home Proximity-based Service Discovery and Communication control Functionality, 简称： H-PDCF)网元中获取 UE的上下文信息，然后向 UE发送注册成功消息，以指示 UE已经获得了在当前拜访地网络内进行 ProSe Public Safety通信的授权，并且还为 UE分配进行 ProSe Public Safety通信的通信参数。从而 UE可以在拜访地网络下进行 ProSe Public Safety通信。 When the UE roams to the visited network, the UE accesses the Visited Proximity-based Service Discovery and Communication Control Functionality (V-PDCF) network element registration request, and the V-PDCF is from the home location. The network information of the UE is obtained in the network element of the Home Proximity-based Service Discovery and Communication Control Functionality (H-PDCF), and then a registration success message is sent to the UE to indicate that the UE has already Authorization to perform ProSe Public Safety communication within the current visited network is obtained, and communication parameters for performing ProSe Public Safety communication are also assigned to the UE. Thus, the UE can perform ProSe Public Safety communication under the visited network.

然而，现有技术中每个网络支持的 Public Safety通信策略不同，该通信策略属于网络的保密信息，拜访地网络可以从归属地网络获取 ProSe Public Safety通信的策略和配置参数，从而造成归属地网络的商业信息的泄露。发明内容 However, in the prior art, the Public Safety communication strategy supported by each network is different, and the communication strategy belongs to the network confidential information, and the visited network can obtain the ProSe Public Safety communication policy and configuration parameters from the home network, thereby causing the home network. The disclosure of business information. Summary of the invention
