Abstract:
1. A communication management apparatus connected to a mobile communication network and a wireless LAN, wherein the mobile communication network includes an authentication apparatus for providing authentication service, and a service server for providing other services, said communication management apparatus comprising: a communication section which, upon reception from a wireless LAN gateway of a connection request reception notification indicating the reception of a connection request from a mobile unit, obtains information indicating a service, provided by the service server of the mobile communication network, that is available to a mobile unit that has sent the connection request; a terminal address determining section which sets a mobile-unit IP address identifying the mobile unit within the wireless LAN when the communication section obtains the information indicating the service; a filter setting section which generates filter information in which information identifying the mobile unit is associated with a mobile-communication-network-service IP address or port number to be used in the service indicated by the information obtained by the communication section, the filter information being an indicator for a switching determination in which packets received by the wireless LAN gateway from the mobile unit for accessing a service provided by the service server of the mobile communication network should be transmitted to a gateway connected to the mobile communication network, and in which packets received by the wireless LAN gateway from the mobile unit for a purpose other than a service provided by the service server of the mobile communication network should be transmitted to a public packet switched network; and a WAG communication section which transmits the filter information set by the filter setting section to the wireless LAN gateway.
