Embodiment 1

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

[0057] For the PON system, the long light emission of the ONU is a serious problem of the system, which may reduce the bandwidth utilization of the PON network, or may lead to the paralysis of the PON system. The ONU with long light emission may be in one of two states, the two states are the successfully registered ONU and the non-registered ONU, which should be determined 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, the suggestions are as follows:

[0061] a) All unregistered ONUs enter the sleep st...

Embodiment 2

[0068] Embodiment 2: Application in ONU authentication mechanism

[0069] The sleep and wake-up mechanism of ONU improves the ONU silence mechanism of telecom enterprises. Use the sleep and wake-up mechanism of the ONU to make the illegal ONU in the sleep state, completely eliminate the opportunity for the ONU to continuously try to register, and at the same time ensure that the OLT can conveniently enable the ability of the ONU device to try to register when it enters the wake-up state. For the registration of the ONU, The OLT completely actively controls its registration, which means that the ONU can only try to register after receiving the command from the OLT's sleep state to wake-up state. This function is very convenient for engineering construction, and can also ensure the security of the network, which can greatly reduce the chance of ONU trying to register. Details are as follows:

[0070] 1. If the unregistered ONU in the sleeping state is required to enter the wak...

Embodiment 3

[0081] Embodiment 3: Realize flexible ONU service control capability

[0082] For ONUs that work normally, they wait to forward service data streams at any time. Utilize the sleeping / wake-up mechanism of the ONU to facilitate the control of services through the ONU state transition, and the source for triggering the transition can be the OLT or the ONU. Described as follows:

[0083] 1. The ONU application enters the sleeping state

[0084] 1) The OLT sets and registers the ONU sleep / wake state description table;

[0085] 2) The ONU sets the status register;

[0086] 3) The ONU applies to enter the sleeping state;

[0087] 4) The OLT gives a permission response to the application of the ONU, and modifies the state description table to change the state description parameters of the ONU;

[0088] 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.

[0089] 2. The O...

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 steps under 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 network, in particular to a method for realizing sleeping and waking up of an optical network unit. Background technique [0002] Due to its large transmission capacity, small transmission channel loss, strong environmental adaptability (adaptation to high / low temperature, adaptation to acid-base environment, etc.), strong anti-interference ability, and good safety, it is favored by users. favor. With the decline of optical fiber transmission costs and the increase of user demand for services, the fiberization of the access network has been greatly promoted, and the passive optical network technology uses passive optical devices to increase the bandwidth of the access network. Reduce the point of failure of the access network, so the passive optical network is the most potential wired access technology for broadband optical access. [0003] Passive Optical Network (PON) technologies main...
