These PON system architectures generally include OLTs, ONUs, and optical distribution networks (ODNs).

[0005] However, in the related art, in the fiber to the room (FTTR) scenario, the uplink rate from the ONU to the OLT is 1.25G, and the downlink rate from the OLT to the ONU is 2.5G, that is, the uplink and downlink rates are asymmetric.

How to achieve an uplink rate of 2.5G from the ONU to the OLT in the FTTR scenario has become a problem that needs to be solved.

[0056] Table 9 Upstream_Overhead message

[0057] In an exemplary embodiment, the OLT sends configuration information to the ONU; wherein the configuration information is used to set a bandwidth map (BWmap) partition for the ONU; wherein the maximum value of the allocation structure of each BWmap partition is D, and when a BWmap is constructed for each physical layer frame (PHY), the ONU is instructed to define multiple different burst allocation series in the BWmap partition according to ascending order of start time, the value range of the start time is 0 to 19438, the maximum value of the allocation structure in each BWmap partition is W, the maximum value of the allocation structure in a burst allocation series is Y, the maximum value of the allocation structure of the ONU in the BWmap partition is Z, and the maximum value of the burst allocation series of the ONU in the BWmap is U; wherein D, W, Y, Z, and U are variables.

[0058] It should be noted that, in this embodiment, based on the above-mentioned additional restrictions when constructing the BWMap for each PHY frame, different values ​​can be assigned to the variables D, W, Y, Z, and U. For example, if the maximum number of allocation structures in a burst allocation series is Y=8, and the maximum number of allocation structures for each given ONU in the BWmap is Z=64, then the maximum number of burst allocation series for each given ONU in the BWmap is Z / Y=8; if the maximum number of burst allocation series for each given ONU in the BWmap is U=8, and the maximum number of allocation structures for each given ONU in the BWmap is Z=64, then the maximum number of allocation structures in a burst allocation series is Z / U=8; if a burst The maximum number of allocation structures in an allocation series is Y = 16, and the maximum number of allocation structures for each given ONU in BWmap is Z = 64, then the maximum number of burst allocation series for each given ONU in BWmap is Z / Y = 4; if the maximum number of burst allocation series for each given ONU in BWmap is U = 16, and the maximum number of allocation structures for each given ONU in BWmap is Z = 64, then the maximum number of allocation structures in a burst allocation series is Z / U = 4; if each BWmap partition can contain a maximum of D = 2047 allocation structures, and the maximum number of allocation structures for each given ONU in BWmap is Z = 64, then the maximum number of ONUs is D / Z = 32.

[0059] In an exemplary embodiment, the OLT allocates an SN request bandwidth to the ONU, and the OLT receives a first message sent by the ONU in response to the SN request bandwidth; when the allocation identifier of the SN request bandwidth is a preset value, the difference between the end time and the start time when the OLT receives the first message is a sixth value or a seventh value.

[0060] For SN request bandwidth response, when the allocated allocid (bandwidth allocation identifier) ​​is 253, 254, or 255, it can also be other appropriate values. The StartTime (start time) and StopTime (end time) values ​​meet the requirements shown in Table 10, that is, the difference between StartTime and StopTime is 6 or 12;

[0061] Table 10 SN requested bandwidth

[0062] In an exemplary embodiment, the OLT allocates a ranging request bandwidth to the ONU, and the OLT receives a second message sent by the ONU in response to the ranging request bandwidth; when the allocation identifier of the ranging request bandwidth is equal to the ONU identifier, the difference between the end time and the start time of the OLT receiving the second message is the sixth value or the seventh value.

[0063] For the ranging request bandwidth response, when the allocated allocid (bandwidth allocation identifier) ​​is equal to the ONU-ID, the values ​​of StartTime and StopTime also meet the requirements shown in Table 11, that is, the difference between StartTime and StopTime is 6 or 12.

[0064] Table 11 Ranging Request Bandwidth

[0065] In an exemplary embodiment, the OLT receives the bandwidth demand of the ONU and allocates bandwidth to the ONU; or, the OLT allocates bandwidth to the ONU according to the bandwidth demand of the wireless local area network air interface.

[0066] In an exemplary embodiment of the present disclosure, the OLT allocates bandwidth to the ONU using the dynamic bandwidth allocation (DBA) function. The bandwidth allocation can be adjusted according to the wireless local area network (WLAN) usage of the master and slave FTTR devices. That is, the bandwidth can be allocated based on the WLAN usage or the future bandwidth usage reported by the slave device and the bandwidth demand of the WLAN air interface. For example, when the WLAN service demand traffic occupies a large amount, the corresponding allocation mechanism is found according to the WLAN service correspondence, and uplink scheduling information is provided. If more bandwidth is required, the master device will increase the bandwidth allocation accordingly after receiving the information.

[0067] Through the embodiments of the present disclosure, since the OLT sends a configuration message to the ONU, the configuration message is used to indicate the uplink rate from the ONU to the OLT in the uplink rate set. The uplink rate in the uplink rate set includes not only 1.25G but also 2.5G. Therefore, the problem in the related art that the ONU cannot operate at an uplink rate of 2.5G can be solved, thereby achieving the effect of sending an uplink rate set including 1.25G and 2.5G to the ONU by the OLT to indicate that the uplink rate from the ONU to the OLT is 1.25G or 2.5G.

[0075] In an exemplary embodiment, the method further includes: the ONU receives the SN requested bandwidth allocated by the OLT, and the ONU sends a first message to the OLT in response to the SN requested bandwidth; when the allocation identifier of the SN requested bandwidth is a preset value, the difference between the end time and the start time of the ONU sending the first message is a sixth value or a seventh value.

[0076] In an exemplary embodiment, the method further includes: the ONU receiving a ranging request bandwidth sent by the OLT, and the ONU sending a second message to the OLT in response to the ranging request bandwidth; when the allocation identifier of the ranging request bandwidth is equal to the ONU identifier, the difference between the end time and the start time of the ONU sending the second message is a sixth value or a seventh value.
