9. An apparatus in a user equipment, comprising:
processing circuitry configured to:
obtain residence parameter information of the user equipment on a target edge computing node of a vehicle-to-everything (V2X) system including a plurality of network levels, the residence parameter information including a ratio of an estimated residence duration of the user equipment accessing the target edge computing node and a message transmission frequency of the user equipment; and
determine one of the plurality of network levels that is a network level of the target edge computing node as a network access level of the user equipment when the ratio of the estimated residence duration and the message transmission frequency is within an access threshold range, the user equipment being configured to access a core network of the V2X system through an edge computing node belonging to the determined network access level during movement of the user equipment, wherein
the target edge computing node is one of a roadside unit (RSU) in the V2X system, a gateway node of a first network level in the V2X system configured to connect with a cluster of road side units, a gateway node at a second network level in the V2X system for connection to a cluster of gateway nodes at the first network level, and a core network node at a core network level in the V2X system.
