Description

一种D2D业务授权的方法及近距离通信服务器Method for D2D service authorization and short-distance communication server 技术领域Technical field
本文涉及但不限于通信领域，尤指一种设备到设备(Device to Device，简称为D2D)业务授权的方法及近距离通信服务器。This document relates to, but is not limited to, the field of communication, especially a device to device (D2D) service authorization method and a short-range communication server.
背景技术Background technique
临近区域的终端利用设备到设备(Device to Device，简称为D2D)直接通信能够给终端带来很多好处，比如更高的速率，更低的延迟以及更小的功耗，同时也极大地提高了运营商的无线资源效率，D2D的Relay(中继)模式有利于运营商提高无线覆盖；对于应用来说利用D2D通讯过程中的临近信息可以开发出更加吸引人的新业务。公共安全(Public Safety)***也可以利用D2D技术实现没有无线覆盖的情况下终端之间的通讯。Direct communication between devices in the vicinity using Device to Device (D2D for short) can bring many benefits to the terminal, such as higher speed, lower latency and lower power consumption, and greatly improved. The radio resource efficiency of the operator, D2D's Relay mode helps operators to improve wireless coverage; for applications, the use of proximity information in the D2D communication process can develop more attractive new services. The Public Safety system can also use D2D technology to enable communication between terminals without wireless coverage.
图1是根据相关技术中和3GPP(The 3rd Generation Partnership Project，第三代合作伙伴计划)相关的D2D架构示意图，如图1所示，重点网元的功能说明如下：FIG. 1 is a schematic diagram of a D2D architecture related to 3GPP (The 3rd Generation Partnership Project) according to the related art. As shown in FIG. 1 , the functions of the key network elements are as follows:
终端：也叫用户设备(User Equipment，简称为UE)，支持终端和终端之间通过空口直接发现对方，无需通过网络，终端和终端间可直接进行通信。Terminal: It is also called User Equipment (UE). It supports the direct discovery of the other party through the air interface between the terminal and the terminal. It does not need to go through the network, and the terminal and the terminal can communicate directly.
核心网网关：也叫分组数据网网关(Packet Data Network Gateway，简称为PDN GW)，设置为为终端提供接入PDN网络的接入点，主要功能包括为终端分配IP地址，将终端发上来的数据包，通过IP转发到对应的PDN网络，将PDN网络发下来的数据包，根据不同的流(flow)映射到不同的承载(bearer)，然后发送到终端。The core network gateway: also called the Packet Data Network Gateway (PDN GW), is configured to provide the access point for the terminal to access the PDN network. The main functions include assigning an IP address to the terminal and sending the terminal up. The data packet is forwarded to the corresponding PDN network through IP, and the data packet sent by the PDN network is mapped to different bearers according to different flows, and then sent to the terminal.
归属签约服务器(Home Subscriber Server，简称为HSS)，位于归属网，主要功能是提供用户和应用的签约信息和认证信息。The Home Subscriber Server (HSS) is located in the home network. The main function is to provide subscription information and authentication information for users and applications.
近距离通信服务器(Prose function)，该服务器位于PDN GW外面，主要功能包括了D2D业务授权、为终端请求的应用分配临时code(编码)，设置为终端广播、协助进行D2D发现以及计费等功能。目前一个公共陆地移动 网络(Public Land Mobile Network，简称为PLMN)只部署一个近距离通信服务器。Proxity server (Prose function), which is located outside the PDN GW. The main functions include D2D service authorization, temporary code (coding) for the application requested by the terminal, setting for terminal broadcast, assisting with D2D discovery, and accounting. . Currently a public land move The Public Land Mobile Network (PLMN) only deploys one proximity communication server.
图2是根据相关技术中的一种D2D业务授权过程示意图，如图2所示，该流程包括如下步骤：FIG. 2 is a schematic diagram of a D2D service authorization process according to the related art. As shown in FIG. 2, the process includes the following steps:
步骤S202，终端和PDN GW之间建立连接，并从PDN GW获取用户IP地址之后，向归属近距离通信服务器发送授权请求。终端根据归属近距离通信服务器的完全合格域名或全称域名(Fully Qualified Domain Name，简称为FQDN)，通过DNS查询到对应的IP地址，然后和该地址进行通信。归属近距离通信服务器的FQDN可以静态配置在终端中，也可以根据归属PLMN ID推导出来。归属近距离通信服务器的IP地址也可以配置在终端中。该授权消息中包含有用户当前驻留的PLMN信息和用户标识IMSI(International Mobile Subscriber Identification Number，国际移动用户识别码)。Step S202, a connection is established between the terminal and the PDN GW, and after the user IP address is obtained from the PDN GW, an authorization request is sent to the home short-range communication server. The terminal queries the corresponding IP address through the DNS according to the fully qualified domain name or the Fully Qualified Domain Name (FQDN) of the home proximity communication server, and then communicates with the address. The FQDN of the home proximity communication server may be statically configured in the terminal or may be derived from the home PLMN ID. The IP address of the belonging proximity communication server can also be configured in the terminal. The authorization message includes the PLMN information currently reserved by the user and the IMSI (International Mobile Subscriber Identification Number).
步骤S204，如果归属近距离通信服务器中没有用户签约信息，则归属近距离通信服务器向归属签约服务器发送获取用户数据请求，以请求用户签约信息，请求中带有用户标识IMSI；Step S204, if there is no user subscription information in the home proximity communication server, the home proximity communication server sends a request for acquiring user data to the home subscription server to request the user subscription information, and the request carries the user identifier IMSI;
步骤S206，归属近距离通信服务器接收到获取用户数据响应，获取签约信息之后，存储在本地数据库中。Step S206, the home proximity communication server receives the response of acquiring the user data, and after acquiring the subscription information, is stored in the local database.
步骤S208，归属近距离通信服务器需要根据获取的PLMN列表向所在的本地近距离通信服务器和/或拜访近距离通信服务器(简称本地/拜访近距离通信服务器)发送授权请求，以获取授权信息及授权的有效时间。Step S208: The home proximity communication server needs to send an authorization request to the local proximity communication server and/or the proximity communication server (referred to as the local/visit proximity communication server) according to the acquired PLMN list to obtain authorization information and authorization. Effective time.
步骤S210，本地/拜访近距离通信服务器返回授权响应，并返回授权的有效时间。In step S210, the local/visited proximity communication server returns an authorization response and returns the validity time of the authorization.
步骤S212，根据用户签约信息和本地配置，归属近距离通信服务器返回授权响应，该授权响应包括该用户的D2D授权信息，该授权信息包括信息：完全授权允许D2D业务的PLMN列表以及用户当前所在位置的本地PLMN列表，以及每个PLMN对应的授权有效时间。UE收到授权信息后，为每个PLMN启动定时器，当定时器超时后，UE需要重新向归属近距离通信服务器发送授权请求。 Step S212, the home proximity communication server returns an authorization response according to the user subscription information and the local configuration, and the authorization response includes D2D authorization information of the user, where the authorization information includes information: a PLMN list that fully authorizes the D2D service and a current location of the user. The list of local PLMNs, and the authorized validity time of each PLMN. After receiving the authorization information, the UE starts a timer for each PLMN. After the timer expires, the UE needs to resend the authorization request to the home short-range communication server.
如果步骤S208中需要向多个本地/拜访近距离通信服务器进行授权，则重复S208-S210的步骤。If it is necessary to authorize a plurality of local/visit proximity communication servers in step S208, the steps of S208-S210 are repeated.
之后，终端将根据授权结果，决定是否发起D2D业务。After that, the terminal will decide whether to initiate D2D service according to the authorization result.
相关技术中当归属近距离通信服务器收到UE的重新授权请求消息后，归属近距离通信服务器仍然需要向所在的本地/拜访近距离通信服务器获取授权信息及授权的有效时间，这就造成了归属近距离通信服务器与本地/拜访近距离通信服务器会产生不必要的信令；另外在归属近距离通信服务器向UE返回重新的授权信息后，UE需要停止已经为授权PLMN启动的授权定时器，然后重新为每个授权PLMN重新启动定时器，UE并且根据重新授权的结果，来决定是否发起D2D业务或者停止已经进行的D2D业务，这也在一定程度上增加了UE的实现复杂度。In the related art, after the home proximity communication server receives the re-authorization request message of the UE, the home proximity communication server still needs to obtain the authorization information and the authorized validity time from the local/visited proximity communication server, which results in attribution. The proximity communication server and the local/visited proximity communication server may generate unnecessary signaling; further, after the home short-range communication server returns the re-authorization information to the UE, the UE needs to stop the authorization timer that has been started for the authorized PLMN, and then The timer is restarted for each authorized PLMN, and the UE decides whether to initiate the D2D service or stops the D2D service that has already been performed according to the result of the re-authorization, which also increases the implementation complexity of the UE to some extent.
针对相关技术中业务授权中归属近距离通信服务器与本地/拜访近距离通信服务器会产生不必要的信令或者UE重新获取授权信息的实现复杂度，目前尚未提出有效的解决方案。For the implementation of the related art, the proximity communication server and the local/visit proximity communication server may generate unnecessary signaling or the implementation complexity of the UE re-acquiring the authorization information, and no effective solution has been proposed yet.
