Abstract
A method of performing an uncontrolled handover data integrity of a target Base Station (BS) is provided. The method includes receiving an initial access request message from a Mobile Station (MS) by the target BS, performing a negotiation for establishing a handover data integrity path with a serving BS through a serving Access Service Network-Gateway (ASN-GW) by the target BS, and generating a main data path and a first handover data integrity path with the serving ASN-GW according to a result of the negotiation by the target BS.
Claims24
A method to perform handover data integrity by a target base station (BS), the method comprising:
- receiving, from a mobile station (MS), an initial access request message if a handover indication message is not received from the MS by a serving BS;
- transmitting, through a gateway, first information related to handover data integrity which is supported by the target BS, to the serving BS;
- receiving, through the gateway, second information related to handover data integrity which is supported by the serving BS based on the first information, from the serving BS;
- and
- determining a handover data integrity scheme from the second information;
- transmitting, to the serving BS, the handover data integrity scheme;
- performing, through the gateway, a negotiation to establish a data path with the serving BS based on the handover data integrity scheme.
A method to perform handover data integrity by a serving base station (BS), the method comprising:
- receiving, through a gateway, first information related to handover data integrity which is supported by a target BS, from the target BS;
- transmitting, through the gateway, second information related to handover data integrity which is supported by the serving BS based on the first information, to the target BS;
- and
- receiving a handover data integrity scheme, which has been determined based on the second information, from the target BS;
- and
- performing, through a gateway, a negotiation to establish a data path with a target BS if the serving BS does not receive a handover indication message from a mobile station (MS) based on the handover data integrity scheme.
A target base station (BS) to perform an uncontrolled handover data integrity, the target BS comprising:
- a receiver configured to:
- receive an initial access request message from a mobile station (MS) if a handover indication message is not received from the MS, and
- receive, through a gateway, second information related to handover data integrity which is supported by a serving BS based on first information related to handover data integrity which is supported by the target BS, from the serving BS;
- a transmitter configured to:
- transmit, through the gateway, the first information to the serving BS,
- transmit a handover data integrity scheme determined from the second information to the serving BS;
- and
- a controller configured to:
- determine the handover data integrity scheme, and
- perform a negotiation to establish a data path with the serving BS through the gateway based on the handover data integrity scheme.
A serving base station (BS) to perform an uncontrolled handover data integrity, the serving BS comprising:
- a receiver configured to:
- receive, through a gateway, first information related to handover data integrity which is supported by a target BS, from the target BS, and
- receive a handover data integrity scheme, which has been determined based on second information, from the target BS;
- a transmitter configured to transmit, through the gateway, the second information related to handover data integrity which is supported by the serving BS based on the first information, to the target BS;
- and
- a controller configured to perform a negotiation to establish a data path with the target BS through the gateway if the serving BS does not receive a handover indication message from a mobile station (MS) based on the handover data integrity scheme.
