  • 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: 8649309
    Abstract: An apparatus and method for creating a data path for a broadcasting service in a cellular network is provided. In a method for creating a data path to provide a broadcasting service in a cellular network, a broadcast server transmits a session start request message to an Access Service Network-GateWay (ASN_GW) before transmission of Multicast and Broadcast Service (MBS) data, to request a multicast connection setup. The ASN_GW establishes a multicast connection between the broadcast server and the ASN_GW on the basis of information of the session start request message. The ASN_GW transmits a session start response message to the broadcast server in response to the session start request message, after establishment of the multicast connection between the broadcast server and the ASN_GW. The ASN_GW transmits a path registration request message to at least one base station associated with a broadcast zone, to request MBS data path establishment and air resource reservation.

  • 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.
