Abstract
Methods and apparatus for notifying a mobile station (MS) of service flow parameters supported by neighbor base stations, such that the MS may select a suitable neighbor base station (BS) candidate (i.e., a target BS) for performing a handover are provided. The notification may occur via handover messages, such as a BS Handover Request (MOB_BSHO-REQ) message or a BS Handover Response (MOB_BSHO-RSP) message, with a Service Level Supported field added, indicating the service flow parameters supported by the neighbor BSs. In this manner, service quality levels of data exchanges may be maintained as an MS is handed over from one BS to another.
Claims84
A method for indicating supported services of a neighbor base station (BS), comprising:
- determining whether a plurality of service parameters are supported by the neighbor BS;
- and
- transmitting a handover message indicating the supported service parameters for the neighbor BS.
A computer-program product for indicating supported services of a neighbor base station (BS), comprising a computer-readable medium having instructions stored thereon, the instructions being executable by one or more processors and the instructions comprising:
- instructions for determining whether a plurality of service parameters are supported by the neighbor BS;
- and
- instructions for transmitting a handover message indicating the supported service parameters for the neighbor BS.
An apparatus for wireless communications, comprising:
- means for determining whether a plurality of service parameters are supported by a neighbor base station (BS);
- and
- means for transmitting a handover message indicating the supported service parameters for the neighbor BS.
A base station, comprising:
- logic for determining whether a plurality of service parameters are supported by a neighbor base station (BS);
- and
- a transmitter front end configured to transmit a handover message indicating the supported service parameters for the neighbor BS.
A method for determining at least one neighbor base station (BS) candidate for handover, comprising:
- receiving a handover message indicating, for each of a plurality of neighbor BSs, a plurality of service parameters that are supported by each neighbor BS;
- and
- based on the supported service parameters indicated by the handover message, selecting the at least one neighbor BS candidate for handover from the plurality of neighbor BSs in the handover message.
A computer-program product for determining at least one neighbor base station (BS) candidate for handover, comprising a computer-readable medium having instructions stored thereon, the instructions being executable by one or more processors and the instructions comprising:
- instructions for receiving a handover message indicating, for each of a plurality of neighbor BSs, a plurality of service parameters that are supported by each neighbor BS;
- and
- instructions for selecting, based on the supported service parameters indicated by the handover message, the at least one neighbor BS candidate for handover from the plurality of neighbor BSs in the handover message.
An apparatus for wireless communications, comprising:
- means for receiving a handover message indicating, for each of a plurality of neighbor base stations (BSs), a plurality of service parameters that are supported by each neighbor BS;
- and
- means for selecting, based on the supported service parameters indicated by the handover message, at least one neighbor BS candidate for handover from the plurality of neighbor BSs in the handover message.
A mobile device, comprising:
- a receiver front end configured to receive a handover message indicating, for each of a plurality of neighbor base stations (BSs), a plurality of service parameters that are supported by each neighbor BS;
- and
- logic for selecting, based on the supported service parameters indicated by the handover message, the at least one neighbor BS candidate for handover from the plurality of neighbor BSs in the handover message.
