Abstract: Disclosed is a method of forming access routers into a virtual-IP zone in a Hierarchical Mobile IP (HMIP) system. The method includes reporting a higher-than-threshold state message to a mobility anchor point by each access router if the number of mobile nodes located in its region and the number of mobile nodes being handed over exceed a predetermined threshold; the mobility anchor point sending a virtual-IP zone forming command for grouping access routers into one group to the access routers if a state report message indicating a higher-than-threshold state is received; and the access routers receiving the virtual-IP zone forming command simulcasting an identical virtual-IP zone's network prefix included in the virtual-IP zone forming command, for grouping.

Abstract: Provided is a handover method, in which a call manager of a network having a Circuit Switching (CS) network, a Long Term Evolution (LTE) network, and an Internet Protocol Multimedia Subsystem (IMS) network, provides handover, from the LTE network to the CS network, to a terminal that uses one radio channel. The handover method includes upon receiving a request for handover from the terminal via a node of the LTE network, establishing a line to a Mobile Switching Center (MSC) of the CS network; sending, to the call manager, a request for a change in a session to another party's terminal in communication with the terminal, to establish an Internet Protocol (IP) bearer between the call manager and the other party's terminal; and sending a handover command to the terminal during the establishment of an IP bearer, to establish a radio channel to the base station of the CS network.

Abstract: Provided is a broadcasting system based on a network using an Internet protocol (IP). In the broadcasting system, a broadcast transmitter previously transmits first access information including a first network address for transmitting a general notification message and second access information associated with management of the broadcasting system, to a broadcast receiver. If a general notification event occurs, the general notification message is generated and the generated general notification message is transmitted to the broadcast receiver via one of a broadcast network and an interaction network using the first network address. The broadcast receiver receives a general notification message based on the first network address in data received from the broadcast transmitter.

Abstract: A roaming service method in a mobile broadcasting system and a system thereof are provided. A terminal receives a service guide from a corresponding visited service provider (Visited SP) when the terminal moves to a roaming area. The terminal transmits a roaming request message for requesting a purchase item allowable for individual services to a home service provider (Home SP) based on the received service guide. Upon receipt of the roaming request message, the Home SP negotiates roaming availability and allowable scope for each individual service with the Visited SP where the terminal is located, based on the roaming request message. The Home SP transmits the roaming availability and allowable scope for the individual service, negotiated with the Visited SP, to the terminal.
