Abstract
A system and method is disclosed for providing a continuous high speed packet data handoff for a mobile station in a wireless network. The system comprises a packet data handoff controller in a source base station that is capable of handing off high speed packet data on a supplemental channel. The packet data handoff controller executes a handoff by sending handoff messages that contain supplemental channel configuration information and Radio Link Protocol (RLP) configuration information. The packet data handoff controller activates a non-retransmission mode of the Radio Link Protocol (RLP). The target base station receives the high speed packet data call starting at a selected Radio Link Protocol (RLP) frame.
Claims20
For use in a wireless network communications system comprising a mobile station, a source base station that is capable of communicating with said mobile station and with a target base station, and a target base station that is capable of communicating with said mobile station and with said source base station, an apparatus for handing off a high speed packet data call from said source base station to said target base station, said apparatus comprising:
- a source base station that is capable of handing off a supplemental channel to a target base station;
- and
- a target base station that is capable of receiving said supplemental channel when said supplemental channel is handed off from said source base station.
For use in a wireless network communications system comprising a mobile station, a source base station that is capable of communicating with said mobile station and with a target base station, and a target base station that is capable of communicating with said mobile station and with said source base station, a method for handing off a high speed packet data call from said source base station to said target base station, said method comprising the steps of:
- providing a source base station that is capable of handing off a supplemental channel to a target base station;
- providing a target base station that is capable of receiving said supplemental channel when said supplemental channel is handed off from said source base station;
- and
- handing off a high speed packet data call from said source base station to said target base station on said supplemental channel.
For use in a wireless network communications system comprising a mobile station, a source base station that is capable of communicating with said mobile station and with a target base station, and a target base station that is capable of communicating with said mobile station and with said source base station, a method for handing off a high speed packet data call from said source base station to said target base station, said method comprising the steps of:
- providing a source base station that is capable of handing off a supplemental channel to a target base station;
- providing a target base station that is capable of receiving said supplemental channel when said supplemental channel is handed off from said source base station;
- activating a non-retransmission mode of a Radio Link Protocol (RLP) in said source base station and in said target base station;
- sending supplemental channel configuration information from said source base station to said target base station;
- sending Radio Link Protocol (RLP) configuration information from said source base station to said target base station;
- handing off a high speed packet data call from said source base station to said target base station on said supplemental channel;
- and
- receiving in said target base station said high speed packet data call on said supplemental channel starting at a selected Radio Link Protocol (RLP) frame identified in said Radio Link Protocol (RLP) configuration information.
