Abstract
For a mobile communications system, a method of allowing a mobile station in idle state to perform handoffs in a more efficient manner is provided. This is achieved by receiving, from a source base station via a first channel, channel information of a second channel that is a different type of channel than the first channel, the second channel being used for transmitting overhead messages by at least one neighboring base station; determining a target base station among the one or more neighboring base stations; and receiving the second channel from the target base station by using the channel information.
Claims22
A method of supporting handoff when a mobile station is in idle mode, the method comprising:
- receiving and storing configuration information of neighboring base stations;
- while checking a strength of pilot channels of the neighboring base stations, detecting a pilot signal strength of a target base station that is greater than that of a source base station;
- checking whether configuration information of the target base station exists among the stored configuration information of the neighboring base stations;
- and
- determining how to perform idle handoff based upon the checking.
The method of 15, wherein the information is provided in a quantity that matches the total number of neighbor base stations.
A method of supporting handoff when a mobile station is in idle mode, the method comprising:
- detecting a pilot signal strength of a target base station that is greater than that of a source base station upon checking pilot channel strengths of multiple neighboring base stations;
- determining whether configuration information of the target base station exists in previously stored configuration information received from the neighboring base stations;
- and
- performing handoff using the stored configuration information of the target base station if the configuration information exists, or returning to a system determination sub-state if the configuration information fails to exist.
The method of 17, wherein the parameters for each neighbor base station are respectively provided, such that the total number of parameters match the total number of neighbor base stations.
