Problems solved by technology

In the process of state migration in sequence, on the one hand, regardless of whether there is uplink or downlink data, the uplink and downlink data transmission clocks are always on in the active held state and active free state, which undoubtedly increases energy consumption; on the other hand, Every time a migration from the Active held state to the Active free state takes more than 10s of migration time, this long migration time will undoubtedly increase the burden on the system processor

Embodiment Construction

[0063] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0064] figure 2 It is the state machine migration schematic diagram of the ONU of the embodiment of the present invention; figure 2 Briefly introduce how the ONU enters the Asleep state from the Active held state and enters the Listen / Watch state from the Active held state.

[0065] When the ONU is successfully registered in the GPON / XGPON system, it enters the Active held state, and when it receives the energy saving indication message sent by the OLT and when the timer expires (Thold expires), it will migrate from the Active held state to the Active free state. And wait for the local LSI and LPI / LDI instructions of the ONU in this state. Wherein, th...

Abstract

Disclosed in embodiments of the present invention are an ONU state transition method, an ONU, and a computer storage medium, the method comprising: when an ONU is at a total sleep state and only downlink data are detected, controlling the ONU to transit from the total sleep state to a free active state, and then transit from the free active state to a semi-sleep state; and when the ONU is at the semi-sleep state and no downlink data is detected, controlling the ONU to transit from the semi-sleep state to the free active state, and then transit from the free active state to the total sleep state.

Description

technical field [0001] The invention relates to optical network unit (ONU, Optical Network Unit) technology, in particular to an ONU state transition method and the ONU. Background technique [0002] The Gigabit Passive Optical Network (GPON, Gigabit-Capable PON) / 10 Gigabit Passive Optical Network (XGPON, 10Gigabit-Capable PON) system is an optical network transmission system with a bus topology, that is, an optical cable terminal equipment (OLT , Optical Line Terminal) to connect multiple ONUs. Due to the large number of ONUs in the GPON / XGPON system, if the ONU can be designed as a device that can effectively save energy, the entire GPON / XGPON system will greatly reduce energy consumption. [0003] figure 1 It is a schematic diagram of state machine migration of an ONU in the prior art. Such as figure 1 as shown, [0004] When the ONU receives a local sleep indication (LSI, Local Sleep Indication) message, it means that there is no data to be transmitted on the uplink...
