Embodiment 1

[0056] Example 1: Alleviating the problem of ONU long light emission

[0057] For a PON system, the long-term light emission of the ONU is a serious problem in the system, which reduces the bandwidth utilization rate of the PON network at light level, and may lead to the paralysis of the PON system at worst. A long-luminous ONU may be in one of two states. The two states are a successfully registered ONU and a non-registered ONU, which should be determined and solved step by step according to the situation. After the OLT device confirms whether any ONU is in the long-lighting state according to the judgment method defined by the manufacturer, the following steps are taken:

[0058] 1) The OLT sets the ONU sleep / wake state description table to mark the state of the currently registered ONU;

[0059] 2) The ONU sets the sleep / wake status register.

[0060] 3) In order to ensure the service flow of the online ONU, it is recommended as follows:

[0061] a) All unregistered ONUs...

Embodiment 2

[0067] Embodiment 2: Application in ONU Authentication Mechanism

[0068] The sleep and wake-up mechanism of the ONU improves the ONU silence mechanism of telecom enterprises. Using the sleep and wake-up mechanism of the ONU, the illegal ONU is put into a sleep state, which completely eliminates the chance of the ONU trying to register continuously. At the same time, it can also ensure that the OLT can conveniently enable the ONU device to attempt registration when it enters the wake-up state. For ONU registration, The OLT fully controls its registration, that is to say, the ONU can try to register only after receiving the command from the OLT to change from the sleeping state to the awake state. Such a function is not only very convenient for engineering construction, but also ensures the security of the network, which can greatly reduce the chances of the ONU trying to register. Details are as follows:

[0069] 1. If the unregistered ONU in the sleeping state is required t...

Embodiment 3

[0080] Embodiment 3: Realize flexible ONU service control capability

[0081] For the ONU that is working normally, it is always waiting to forward the service data flow. Using the sleep / wake mechanism of the ONU, it is convenient to control the service through the ONU state transition. The source of triggering the transition can be the OLT or the ONU. Described as follows:

[0082] 1. The ONU application goes to sleep

[0083] 1) OLT settings register ONU sleep / wake state description table;

[0084] 2) ONU sets the status register;

[0085] 3) The ONU application enters a sleeping state;

[0086] 4) The OLT gives a permission response to the application of the ONU, and modifies the state description table and changes the state description parameters of the ONU;

[0087] 5) The ONU receives the response message from the OLT, modifies the local register---changes its own state description parameters, and enters the sleeping state.

[0088] 2. The ONU applies to enter the ...

Abstract

The invention discloses a method for realizing a sleeping and waking mechanism of an optical network unit (ONU) of a passive optical network, which comprises: arranging a register on an ONU device specially used for storing a sleeping / waking state parameter of the ONU device; arranging a descriptive list for the sleeping / waking state of the ONU device on an OLT; and then, adopting different stepsunder the triggering case of the ONU device from the sleeping state to the waking state or from the waking state to the sleeping state. The invention enhances the ability of the OLT to control the ONU and enhances the judging ability of the ONU in the meantime.

Description

technical field [0001] The invention relates to the technical field of passive optical networks, in particular to a method for realizing sleep and wake-up of optical network units. Background technique [0002] Optical fiber is favored by users because of its large transmission capacity, small transmission channel loss, strong adaptability to the environment (adaptation to high / low temperature, adaptability to acid and alkali environments, etc.), strong anti-interference ability, and good safety. favor. With the decline in the cost of optical fiber transmission and the increase in user demand for services, the optical fiberization of the access network has been greatly promoted, and the passive optical network technology uses passive optical components to improve the bandwidth of the access network. To reduce the failure points of the access network, passive optical network is the most potential wired access technology to realize broadband optical access. [0003] Passive ...
