Abstract
A method and apparatus facilitate soft handover in a CDMA RAN (100) based on a requested set of soft handover parameters from a plurality of sets of soft handover parameters associated with a corresponding plurality of radio configurations. A mobile station (140) can request a set of soft handover parameters associated with a radio configuration. Candidate base stations (BTS 1-BTS N) can be added to an active list based on the soft handover parameters.
Claims19
A method for facilitating the transfer of handoff parameters associated with a handoff of a call including a wireless communication unit from a first base station to a second base station in a Radio Access Network (RAN), the method comprising:
- notifying the first base station of a chosen one of a plurality of radio configurations chosen for operation by the wireless communication unit for use during the call, the notifying performed during a call setup procedure associated with the call;
- the plurality of radio configurations having a corresponding plurality of sets of handoff parameters associated therewith;
- and
- receiving a first one of the plurality of sets of handoff parameters associated with the chosen one of the plurality of radio configurations transferred from the first base station to the wireless communication unit.
A method for facilitating the transfer of handoff parameters associated with a soft handover of a call including a wireless communication unit in a Code Division Multiple Access (CDMA) Radio Access Network (RAN), the method comprising:
- maintaining a set of soft handover parameters for each of a plurality of radio configurations associated with the CDMA RAN to form a plurality of sets of soft handover parameters;
- receiving a notification of a chosen one of the plurality of radio configurations chosen for operation by the wireless communication unit;
- and
- transferring a first one of the plurality of sets of soft handover parameters corresponding to the selected one of the plurality of radio configurations to the wireless communication unit.
An apparatus for facilitating a handoff of a call including a wireless communication unit in a Code Division Multiple Access (CDMA) Radio Access Network (RAN), the apparatus comprising:
- an RF interface communicatively coupled to the CDMA RAN;
- a memory;
- and
- a processor communicatively coupled to the memory and the RF interface, the processor configured to:
- maintain a set of soft handover parameters for each of a plurality of radio configurations associated with the CDMA RAN to form a plurality of sets of soft handover parameters.
