摘要： An operating method, a base station, and terminal of a cell of a first communication system for a handover between the first communication system and a second communication system are provided. The method includes, when a terminal initiates a handover between the first communication system and the second communication system, transmitting, by the base station, a message, requesting to measure a signal level of a downlink, to the terminal, when a signal level measured by the terminal falls below a preset threshold, requesting, by the base station, a handover to the second communication system over a core network, receiving, by the base station, a message, including radio channel parameters the that is required when the terminal accesses to the second communication system, from the second communication system, and forwarding, by the base station, the message, including the radio channel parameters of the second communication system, to the terminal.

摘要： An apparatus and method for determining operation of location update in a broadband wireless communication system are provided. The apparatus includes a receiver, an interpreter, and a determiner. In an idle mode, the receiver receives a paging advertisement message from a Base Station (BS). The interpreter identifies paging group identification information included in the paging advertisement message. The determiner determines one of execution and non-execution of a location update process due to a change of a paging group if the paging group identification information is different from paging group identification information included in a previously received paging advertisement message.

摘要： An apparatus and a method for handover between a broadband wireless communication system and a heterogeneous communication system are provided. An operating method of a base station for the handover between a broadband wireless communication system and a and a heterogeneous communication system includes when a terminal enters a border cell, sending a message requesting to measure a signal level of a downlink, to the terminal, when a signal level measured by the terminal falls below a preset threshold, requesting a handover, to a corresponding heterogeneous communication system, over a core network, receiving a message, including channel allocation information for the handover, from the corresponding heterogeneous communication system, and forwarding the message, including the channel allocation information, to the terminal. Hence, when the terminal gets out of the service coverage area of the broadband wireless communication system, it can be handed over to the heterogeneous communication system seamlessly.
