Method of uplink IP packet filtering control in mobile terminal
First Claim
1. A method for controlling uplink IP packet filtering, comprising:
- an information receiving operation of receiving IP address information allocated to a user equipment, and filtering information required for delivering an uplink IP packet received from the user equipment; and
a filtering operation of determining a packet data network and a bearer to which the IP packet received from the user equipment is delivered, based on the IP address information and the filtering information,wherein the filtering operation comprises;
checking a source IP address of the received IP packet;
checking if an address allocation type for the user equipment is dynamic-stateful autoconfiguration and there is a packet data network having no IP address currently allocated to the user equipment when the source IP address is not set;
delivering the received IP packet through a default bearer when there is the packet data network as the check result; and
discarding the received IP packet when there is no packet data network.

Abstract
A method for controlling uplink IP packet filtering in a mobile terminal in a 3GPP Evolved Packet System (EPS) is provided, including an information receiving operation of receiving IP address information allocated to user equipment, and filtering information required for delivering an uplink IP packet received from the user equipment; and a filtering operation for determining which packet data network and a bearer the IP packet is delivered to, based on the IP address information and the filtering information. In a 3GPP evolved packet system supporting a default bearer function, a packet data network to which an uplink IP packet is delivered and a bearer identifier can be efficiently determined when the user equipment simultaneously accesses one or more packet data networks and is allocated several IP addresses, resulting in effective uplink packet filtering.
