Application: Method and apparatus for providing multi virtual local area network service supporting device to device communication (Patent ID: US20240098022A1)
The patent filed by KT Corp. describes a method and apparatus for providing a multi virtual local area network (VLAN) service to user equipment. The method involves storing VLAN routing information that includes user equipment information and session information, receiving data from a user equipment, determining if the data is a VLAN routing target based on the extracted information, and transmitting the data to the corresponding destination user equipment. The system uses session identifiers, IP addresses, network identifiers, and VLAN group identifiers to route the data effectively between user equipments subscribing to the multi VLAN service.
Furthermore, the apparatus includes a memory to store VLAN routing information and a processor to create VLAN routers for relaying communication between user equipments in the same VLAN group. The routers determine if the received data is a VLAN routing target based on the extracted user equipment and session information, converting session identifiers as needed. Additionally, the apparatus includes a packet detection circuit to analyze data based on packet detection rules and forward it to the appropriate VLAN router. The system also handles scenarios where the VLAN group identifiers are not identical, discarding data if necessary. Overall, the method and apparatus described in the patent aim to efficiently provide a multi VLAN service to user equipments by utilizing detailed routing information and intelligent routing mechanisms.
