[0024] In this embodiment, a master-slave device communication method for FTTR running on the above-mentioned mobile terminal or network architecture is provided. FIG3 is a flow chart of the master-slave device communication method for FTTR according to an embodiment of the present disclosure. As shown in FIG3 , the flow chart includes the following steps:

[0025] Step S302: A corresponding OMCI channel is established between the FTTR master device and the slave device according to the uplink mode of the slave device;

[0026] In an exemplary embodiment, a corresponding passive optical network management and control interface OMCI channel is established according to the uplink mode of the slave device, including: when the uplink mode of the slave device is Ethernet or wireless, the master device establishes a passive optical network management and control interface OMCI channel with the slave device based on the Ethernet frame; when the uplink mode of the slave device is a passive optical network PON, the master device establishes an OMCI channel with the slave device based on the GEM frame.

[0027] Step S304: The master device receives an attribute value change AVC notification from the slave device via the OMCI channel.

[0028] In an exemplary embodiment, the master device receives an attribute value change AVC notification from the slave device through the OMCI channel, including: the master device receives the AVC notification from the slave device through the OMCI channel, and the AVC notification includes at least an operation status attribute field of the access node port entity of the slave device.

[0029] In actual implementation, the operation status attribute field of the AVC notification can be used to indicate whether the status of the slave device is a deactivated state or an activated state.

[0030] In an exemplary embodiment, the types of the access node port entity include at least: an Ethernet access node port entity; a wireless access node port entity; and a PON access node port entity.

[0031] In an exemplary embodiment, an Ethernet access node port entity includes at least: a managed entity number attribute field, an operation status attribute field, a management status attribute field, a maximum bit rate attribute field, a current bit rate attribute field, and a duplex mode attribute field; a wireless access node port entity includes at least: a managed entity number attribute field, an operation status attribute field, a management status attribute field, an access frequency band attribute field, a wireless signal strength attribute field, an access channel attribute field, and an uplink and downlink negotiated rate attribute field; and a PON access node port entity includes at least: a managed entity number attribute field, an operation status attribute field, and a management status attribute field.

[0032] In actual implementation, different types of access node port entities may have different field settings, and the field content may be adjusted according to actual conditions.

[0033] Step S306: The master device receives the serial number of the slave device according to the AVC notification and completes the SN authentication of the slave device's secondary node.

[0034] In an exemplary embodiment, the master device receives the serial number of the slave device based on the AVC notification and completes the SN authentication of the slave device's auxiliary node, including: when the AVC notification indicates that the operating status of the slave device is activated, the master device sends a query message to query the serial number of the slave device; the master device receives the serial number reported by the slave device; and the master device performs SN authentication on the slave device.

[0036] In actual implementation, if the slave device has been registered on the master device, the authentication will be successful; if the slave device has not been registered on the master device, the authentication will fail.

[0037] Step S308: The master device initiates master information block (MIB) synchronization to the slave device based on the SN authentication, so as to enable communication between the master device and the slave device.

[0038] In an exemplary embodiment, after the master device initiates master information block (MIB) synchronization to the slave device, the method further includes: the master device sending a configuration instruction or query message to the slave device; and the master device receiving alarm information or AVC notification reported by the slave device.
