Provided are an information transmission method and apparatus, an information processing method and apparatus, a terminal, a network element, and a storage medium. The information transmission method includes encapsulating non-access stratum (NAS) information and access resource (AS) parameter information in a vendor-specific protocol (VSP) packet, where the NAS information includes NAS system information and NAS customization information, and the AS parameter information is used for wired side resource negotiation; encapsulating establishment signaling of a wired access network control plane channel in a vendor-specific network control protocol (VSNCP) packet; and transmitting, through the VSP packet and the VSNCP packet, the NAS information and the AS parameter information.
