Multi-link terminal, method for allocating an address for a multi-link terminal, network access device and medium

A method for allocating an address for a multi-link terminal, comprising:

• receiving, by a second logical entity affiliated with a network access device, an association request message sent by the multi-link terminal, wherein the association request message comprises a MAC address of the multi-link terminal, and the MAC address comprises a link information bit for indicating that the MAC address is an address of the multi-link terminal;
• allocating, by the network access device, addresses and association identifiers for logical entities affiliated with the multi-link terminal;
• and
• sending, by the second logical entity, an association response message to the multi-link terminal, wherein the association response message comprises the addresses and the association identifiers allocated by the network access device for the logical entities affiliated with the multi-link terminal, wherein the addresses for the logical entities comprise respective link information bits, and the link information bits in the addresses for the logical entities are respective link identifiers,
• wherein the allocating, by the network access device, the addresses and the association identifiers for the logical entities affiliated with the multi-link terminal comprises:
• allocating the addresses for the logical entities affiliated with the multi-link terminal according to link identifiers and the MAC address of the multi-link terminal in the case that the link information bit in the MAC address of the multi-link terminal indicates that the MAC address is an address of the multi-link terminal, wherein the link identifiers are respective link identifiers corresponding to operable links of the network access device;
• and
• allocating the association identifiers for the logical entities that have been allocated with the addresses.
