Description

一种通信系统的远程带外管理方法及系统 Remote management method and a system band of a communication system

技术领域 FIELD

[0001] 本发明属于通信技术领域,涉及一种通信系统的远程带外管理方法及系统。 [0001] The present invention belongs to the field of communication technology, relates to a communication system for remote management methods and systems with the outer.

背景技术 Background technique

[0002]目前使用的网络管理手段基本上都是带内管理,即控制管理信息与数据信息使用同一通道进行传送。 [0002] Network management tools currently in use are substantially in-band management, i.e. management information and control data transmitted using the same channel. 常用的HP Openview网络管理软件就是典型的带内管理系统,该系统中数据信息和管理信息都是通过网络设备以太网端口进行传送。 HP Openview common network management software is a typical in-band management system, the data information and management information systems are transmitted through the Ethernet port network devices. 带内管理的最大缺陷在于:当该通道出现故障中断时数据信息和管理信息都无法正常传输。 The biggest drawback in-band management is: When the channel fails interrupting data information and management information can not be transmitted properly.

[0003] 例如在宽带接入系统中,用户接入设备(如MODEM)的远程管理十分重要。 [0003] For example in a broadband access system, the user access device (e.g., MODEM) remote management is very important. 用户设备所对应的通信链路处于整个宽带接入系统的末端,这段链路的情况最为复杂多变,突发噪声或窄带噪声都可能引起链路中断。 Corresponding to the user equipment at the end of a communication link over a broadband access system, where this link is the most complex, the burst noise or a narrowband noise may cause a link break. 此时可能需要调整数据链路的通信模式(如调制编码方式),以降低数据率的方式来换取系统抗干扰性的提高。 At this time, the communication mode may need to adjust the data link (e.g., modulation and coding scheme), the way to reduce the data rate to improve the noise immunity of the exchange system. 但是由于原先的链路(采用原先的通信模式)已中断,无法将控制信息通过原先的链路传递给远端的用户接入设备,也就无法将用户接入设备设为新的通信模式。 However, due to the original link (using the original communication mode) has been interrupted, the control information can not be transmitted to the distal end of the previous link of the user access device, the user will not be able to access the device as a new mode of communication. 此时只能派检修人员如户去调试,这不仅成本高,而且十分麻烦耗时。 At this point you can only send maintenance personnel to debug, such as households, which is not only costly, time-consuming and cumbersome.

[0004] 为克服上述缺陷,技术人员想到了带外管理的方式。 [0004] In order to overcome the above drawbacks, the art thought embodiment of band management. 带外管理的核心理念是通过不同的通道传送控制管理信息和数据信息,控制管理信息和数据信息完全独立,互不影响。 The core concept of band management channel is transmitted through different management information and control data information, control and management information and data information is completely independent of each other. 当传送数据信息的通道(即带内通道)出现故障时,仍可以利用另一条通道(即带外通道)来管理设备,系统监测和恢复。 When transferring data channel information (i.e., channel band) fails, you can still use the other path (i.e., channel band) to the management device, system monitoring and recovery. 因此带外管理可以弥补带内管理的不足。 So-band management can make up for lack of in-band management. 但是一般情况下,远程带外管理的路径在物理上是与带内管理的路径是分开的,这无疑会直接增加运营商的成本。 But under normal circumstances, the path to the remote band management is physically in-band management paths are separate, which undoubtedly will directly increase the cost of the operator.
