An apparatus for managing a security policy of a firewall according to an embodiment includes a rule request module that receives one or more requested rules to be applied to a firewall, a rule merge module that merges a pre-applied rule of the firewall and the one or more requested rules when the number of rules applied to the firewall exceeds a maximum number of rule registrations of the firewall due to the requested rule, and a firewall interface module that receives the pre-applied rule from the firewall and provides the pre-applied rule to the rule merge module, and re-registers a merged rule merged through the rule merge module in the firewall, and the rule merge module is configured to merge the pre-applied rule and the one or more requested rules so that a security vulnerable space occurring due to the merging is minimized.

Apparatus and method for managing security policy of firewall

An apparatus for accessing a wireless network includes an access manager configured to request access to a wireless network according to a wireless network access condition including at least one desired service set identifier (SSID); and a wireless network access module configured to search for at least one wireless network corresponding to the at least one desired SSID, and access the searched at least one wireless network.

Apparatus and method for accessing wireless network

Provided are a system and method for setting an adaptive set of handoff parameters. The system includes a user terminal configured to transmit an authentication request to a network and receive a set of handoff parameters from the network; an access point (AP) belonging to the network and configured to receive the authentication request from the user terminal, transmit the authentication request to a central management server, receive the set of handoff parameters from the central management server, and transmit the set of handoff parameters to the user terminal; and the central management server, which is configured to store and manage a plurality of network-specific sets of handoff parameters for one or more networks, authenticate the user terminal using the authentication request received from the AP, and transmit a set of handoff parameters of a network to which the authenticated user terminal connects to the AP.

System and method for setting adaptive handoff parameters

A channel allocating method for random access is disclosed, which is suitable for allocation of uplink RACH in a radio access network and by which random access processing performance in a radio access network is enhanced using RACH of new structure. The present invention includes the steps of setting up a channel area (I) dedicated for new access attempt among random access channels of a prescribed frame (t) and allowing a mobile terminal to attempt access to an access point via a prescribed random access channel corresponding to the channel area (I).

Channel allocating method for random access

A reserved channel allocating method in a mobile radio communication system which can adaptively control the allocation of the number of reserved channels using a fuzzy logic controller in accordance with the fluctuant handoff traffic density. According to this method, the traffic density of handoff calls is identified for a period determined by a base station, and the ratio of the number of normal channels for processing initial calls and the handoff calls to the number of reserved channels for processing the handoff calls is adjusted in accordance with the traffic density of the handoff calls.
