摘要： In a communication system, a Mobile Station (MS) transmits a Multicast/Broadcast Service (MCBCS) authentication information transmission request message to an MCBCS server, and receives MCBCS authentication information from the MCBCS server in response to transmission of the MCBCS authentication information transmission request message. The MCBCS authentication information is information that the MCBCS server has derived using MCBCS MS profile information managed by an Authorization, Authentication and Accounting (AAA) server according to the MCBCS authentication information transmission request message, and the MCBCS MS profile information includes a random seed allocated to at least one MCBCS channel serviceable by the MS.

摘要： A method for performing a handoff between a wireless local area network (LAN) including an access router (AR) supporting an Internet protocol (IP) routing function and a mobile communication network including a packet data service node (PDSN) connected to a base station system (BSS), for supporting the IP routing function. An access terminal (AT) detects its movement from the wireless LAN to the mobile communication network, and exchanges information for tunneling between the AR and the PDSN, with the PDSN. The PDSN sets up a tunnel for packet delivery between the PDSN and the AR, and delivers packets to the AT through the set tunnel.
