Description

—种控制DLNA设备服务权限的方法和DLNA设备 - the kind of control equipment service DLNA DLNA device and method permissions

技术领域 FIELD

[0001] 本发明涉及数字移动网络联盟(DLNA),尤其涉及一种控制DLNA设备服务权限的方法和DLNA设备。 [0001] The present invention relates to a digital mobile network alliance (DLNA), in particular, it relates to a control method DLNA device and service permissions DLNA device.

背景技术 Background technique

[0002]数字移动网络联盟(DLNA,DIGITAL LIVING NETWORK ALLIANCE),其宗旨是Enjoyyour music,photos and videos,anywhere anytime。 [0002] Digital Mobile Network Alliance (DLNA, DIGITAL LIVING NETWORK ALLIANCE), whose purpose is Enjoyyour music, photos and videos, anywhere anytime. DLNA 由索尼、英特尔、微软等公司发起成立、g在解决个人PC,消费电器,移动设备在内的无线网络和有线网络的互联互通。 DLNA by Sony, Intel, Microsoft and other companies initiated the establishment, g interoperable connectivity solutions in personal PC, consumer electronics, mobile devices, including wireless and wired networks.

[0003] UPnP是面向易用性设计的DLNA网络协议集的核心部分,是设备连入DLNA网络的最普适的方式,是设备通过DLNA网络通信的公共协议。 [0003] UPnP is a DLNA network protocol set for ease of design of the core part, the device is connected to the most universal way DLNA network, the device is communicating through a common protocol of the DLNA network. UPnP建立在被广泛接受和普遍适用的互联网协议之上,来自不同厂商的设备非常容易就可以工作在一起,从而实现“任何时间,任何地点”的内容共享和计算。 UPnP builds on widely accepted and universally applicable Internet protocol, devices from different manufacturers is very easy to work together to achieve content "anytime, anywhere" and shared computing. UPnP从设备的寻址、查找、控制、事件、表现五个方面定义了DLNA网络设备间互操作机制。 UPnP from addressing equipment, find, control, event, performance in five areas defined in the operating mechanism of interaction between DLNA network devices.

[0004] UPnP规定如果ー个DLNA设备加入DLNA网络获得IP地址,需要运用SSDP协议定时发送广播自己的部分设备信息和服务信息,以便感兴趣的DLNA控制点能找到。 [0004] UPnP DLNA provides that if a device is added ー DLNA network to obtain IP addresses, you need to use SSDP broadcast regularly sends out some of the equipment information and service information of their own, in order to DLNA control point of interest can be found. 而如果一个DLNA控制点加入DLNA网络获得IP地址,会运用SSDP协议发送一个搜索请求在网络上捜索其感兴趣的设备。 If a DLNA DLNA network control point is added to obtain an IP address, use SSDP protocol to send a search request over the network its interest Dissatisfied cable device.

[0005] DLNA控制点通过接收DLNA设备接收到搜索请求后返回的发现消息,可了解设备类型、设备名称和ー个指向具有XML格式的设备描述文档的指针。 Returning discovery message [0005] DLNA DLNA device by receiving a control point search request is received, the device type can be appreciated, a device name and a pointer to a ー device description document of the XML format. DLNA控制点为了对DLNA设备了解的更多,要依据发现消息中所述指向具有XML格式的设备描述文档的指针找到所述设备描述文档,从所述设备描述文档中读取更多的描述信息。 DLNA control point of the DLNA device in order to know more, according to the discovery message in a pointer to a device description file in XML format to find the device description document, reading additional information from the device description document description . 描述信息的范围很广,一般都是由设备的制造厂商提供的,可包括:控制的模式名称和模式号码、设备序列号、制造厂商名称、厂商的WEB的URL,以及所嵌入的设备或服务的描述信息和设备控制、设备事件、设备表达的URL。 Describes a wide range of information, generally provided by the manufacturer of the device, may include: a mode control mode number and a name, serial number, manufacturer's name, URL WEB manufacturers, as well as embedded devices or services description information and device control, device events, expressed device URL.

[0006] DLNA控制点找到上述设备描述信息后,会从设备描述信息中提取出要进行的操作并获悉所有的服务。 [0006] DLNA found after the above-described control point device description information, extracts the information from the device description in the operation to be performed and informed all services. 如果DLNA控制点要控制某个DLNA设备,DLNA控制点会先向该DLNA设备发送服务控制消息一个服务控制请求,请求DLNA设备开始服务;然后DLNA控制点按DLNA设备表达的URL发送相应的控制消息,控制消息就是放置在XML文件中的SOAP格式的信息;最后,DLNA控制点接收DLNA设备返回的服务结果,指示服务是成功或失败。 If the control point to control a DLNA DLNA device, the control point will first DLNA DLNA device transmitting the service control message controls a service request, the service request starts a DLNA device; DLNA control point then sends a corresponding control message expressed by URL DLNA device the control information is placed in the SOAP format message XML file; Finally, the control point receives a service result DLNA DLNA device is returned, indicating success or failure of the service.

[0007] 由于UPnP协议没有规定安全保障机制,所以使支持UPnP协议的DLNA设备完全暴露在无保护的状态下,以致任何跟DLNA设备在同一个网段的DLNA控制点都能对其所有服务进行控制操作。 [0007] Since the UPnP protocol does not specify security mechanism, so the supports UPnP protocol DLNA device is fully exposed to the unprotected state, so that all its services can be carried out any DLNA device with DLNA control point in the same network segment control operations. 因此如何保障DLNA设备的安全成为亟待解决的问题。 So how to protect the safety of DLNA device becomes a problem to be solved.
