Preferred embodiment

The 1905.1 Protocol, also known as the Institute of Electrical and Electronics Engineers (IEEE) standard converged digital home network heterogeneous technology, defines an abstraction layer for multiple home networking technologies. This abstraction layer provides a common data and control service access point for heterogeneous home network technologies. These heterogeneous home network technologies include: IEEE Std 1901TM-2010, IEEE Std 802.11TM-2012, IEEE Std 802.3TM-2008 And MoCA, and this standard is extensible. In addition, the standard specifies all procedures, protocols and guidelines to simplify the user experience: such as adding devices to the network, creating new encryption keys, extending network coverage, and providing network management functions such as: Neighbor Discovery , topology discovery, interface selection, QoS negotiation and network control management.

The automatic configuration protocol based on the 1905.1 protocol provided by the embodiment of the present invention (Protocols for

IEEE 802.11 access point autoconfiguration with IEEE Std 1905.1) is part 10 of the 1905.1 protocol, which uses CMDUs to transfer Registrar's IEEE 802.11 parameters to Enrollee to establish the initial configuration of the Enrollee IEEE 802.11 interface or to update its existing configuration. This action provides an automated way to set up extended service sets for multiple APs and keep them in sync. 1905.1 The automatic configuration protocol consists of two phases: Obtaining the Registrar discovery phase and the configuration phase of IEEE 802.11 parameters in the 1905.1 network environment where the Registrar (registration) is reachable; the IEEE 802.il parameter configuration phase mainly completes the Registrar and Enrollee (involved) Configuration transfer. The 1905.1 abstraction layer provides a transparent transport protocol for WSC frames M1 and M2.

5502, Registrar CPE responds to Auto config search resp (bandl) after receiving the Auto config search req of Enrollee API and Enrollee AP2, then API and AP2 think Registrar is available; S503, API and AP2, after the Registrar exists, send a wireless Ml message (Auto config wps) to the CPE;

S504, the CPE encapsulates its wireless configuration into a wireless M2 message (Auto config wps), and sends it to the API and AP2;

After the API and AP2 receive the M2 message, they are configured according to the wireless configuration in the M2 message. The M2 message includes an SSID name, an encryption method, a key, and the like.

S505-S508 is a radio frequency (band2) configuration process. After both band1 and band2 are configured, the configuration of Registrar CPE and Enrollee AP is synchronized.
