  • Patent number: 9408110
    Abstract: A network includes a Mobile Station (MS) for sending a Service Flow (SF) modification request message to a Base Station (BS) to modify an SF. The BS sends a path modification request message to a serving SF Authorization (SFA) when there is the information on the SF. The BS also sends an SF modification response message comprising a Confirmation Code ‘Reject SF not found’ to the MS when there is no information on the SF. The serving SFA sends a resource reservation request message to an anchor SFA when there is the information on the SF, and sends a path modification response message comprising a Failure Indication (FI) ‘Requested Context Unavailable’ to the BS when there is no information on the SF. The anchor SFA sends a resource reservation response message comprising the FI ‘Requested Context Unavailable’ to the serving SFA when there is no information on the SF.

  • Patent number: 9100915
    Abstract: An apparatus and method for a base station to control a state of a mobile station based on a traffic condition of the mobile station are provided. The terminal operation control method includes controlling a terminal having ongoing traffic while the terminal is in an awake state, determining whether a pseudo awake timer of the terminal expires, wherein the pseudo awake timer counts a time for which the terminal in the awake state has no traffic, withdrawing, when the pseudo awake timer expires, a resource allocated to the terminal, and transitioning the state of the terminal to a pseudo awake state.

  • Publication number: 20120281627
    Abstract: A method and apparatus for providing a Voice over Internet Protocol (VoIP) service using a Payload Header Suppression (PHS) method in a mobile communication system are provided. The method includes extracting header information by analyzing a Session Description Protocol (SDP) offer message that is included in a Session Initiation Protocol (SIP) signaling message received from a Worldwide Interoperability for Microwave Access (WiMAX) system, generating a Classification (CS) rule based on the extracted header information, determining whether to generate a new service flow based on the extracted header information, generating a PHS rule using a Dynamic Service Addition (DSA) when the new service flow is generated, and generating the PHS rule using a Dynamic Service Change (DSC) when the new service flow is not generated, and transmitting the generated CS rule and PHS rule to the WiMAX system.

  • Patent number: 8270353
    Abstract: An apparatus and method are provided for load balancing in a broadband communication system. In an initial network entry/network reentry/handover, whether to allow a user terminal and whether to allow each service flow are checked. The channel state and load state of candidate frequency assignments and subcells are detected. The ranging status of a corresponding frequency assignment or a corresponding subcell is set according to whether to allow the user terminal. The allowable candidate frequency assignment and subcells are selected and transmitted.

  • Publication number: 20120039301
    Abstract: A method for controlling a Hybrid Automatic Repeat Request (HARQ) of a mobile communication system is provided. The method includes establishing a default Best Effort (BE) connection, transmitting, when a Dynamic Service Addition (DSA) is request for a new service, an Advance Air Interface_Registration-Request (AAI_DSA-REQ) message including HARQ channel mapping information from a base station to a mobile station, and transmitting, when the AAI_DSA-REQ message is received from the base station, an Advance Air Interface_Dynamic Service Addition-Response (AAI_DSA-RSP) message from the mobile station to the base station in order to establish a HARQ channel based on the HARQ channel mapping information.
