Abstract:
The present invention relates to a broadband wireless access system, and more particularly, to a method in which an advanced mobile station efficiently acquires information on a peripheral legacy base station in a mobile communication system in which a legacy system and an advanced system coexist. According to one exemplary embodiment of the present invention, a method in which a mobile station receives, from a serving base station operating in a mixed mode, information on a peripheral base station in a mobile communication system in which a legacy system and an advanced system coexist comprises: a step of receiving a second message containing time information for receiving, through a second region of the serving base station, a first message broadcasted through a first region of the serving base station; and a step of receiving the first message through the first region of the serving base station using the time information. The first message contains system information on the base station existing near the serving base station and supporting only the legacy system and/or on the first region of the base station existing near the serving base station and operating in the mixed mode.
Abstract:
A method of communicating information in a wireless mobile communication system is disclosed. More specifically, the method includes a network for establishing handover management modules in a source network and a target network and transmitting a handover request message from the handover management module of the source network to the handover management module of the target network. Furthermore, the network is used for receiving a handover response message from the handover management module of the target network to the handover management module of the source network, wherein the handover response message includes an internet protocol address information and transmitting a handover confirmation message from the handover management module of the source network to a mobile terminal, wherein the handover confirmation message includes the internet protocol address information.
Abstract:
A method of transmitting network information in a broadband wireless access system is disclosed, in which a base station transmits mobile IP information received from a HA or FA to a mobile station in an idle mode. The present invention includes the steps of receiving a request for entering an idle mode from a mobile station, transmitting information of an admission for entering the idle mode to the mobile station, receiving the network information from a mobility agent, and transmitting a paging message including the network information.
