摘要： A Radio Network Controller (RNC) in a high speed wireless communication system includes an apparatus to perform method for changing a serving cell in the high speed wireless communication system. The RNC receives UpLink (UL) cell change determination information representing UL channel states from a serving Base Station (BS) and a target BS. The UL is received if a UL soft handover of a Mobile Station (MS) is initiated depending on a DownLink (DL) channel quality of the MS. The RNC can determine UL cell change timing of the MS using the UL cell change determination information. Thereafter, the RNC can send an instruction of a UL cell change of the MS to the serving BS and the target BS.

摘要： Disclosed is a method for optimizing hard handoffs, e.g., between Mobile Switching Centers in a CDMA network. In the method, preliminary conditions for a hard handoff test are first set up. Idle handoffs are then performed in a hard handoff area, log data for the idle handoffs is analyzed and adjustments to communication equipment are made accordingly. Next, hard handoff tests are conducted in a traffic state in the hard handoff area. Log data of the hard handoff tests are analyzed and further adjustments to communication equipment are made if hard handoff performance during the hard handoff tests is determined to be unsatisfactory. A final hard handoff confirmation test is then performed in the hard handoff area following the latter communication equipment adjustments.

摘要： An apparatus is configured to allocate an IDentification (ID) cell to avoid duplication of a preamble Pseudo Noise (PN) code in a broadband wireless communication system. The apparatus selects one sector inside the system. A temporary ID cell for the selected sector is selected. Whether an ID cell of a sector to which an ID cell has been already allocated inside a minimum unit group for ID cell allocation is the same as the temporary ID cell is determined. Whether PN codes of sectors inside a neighbor list of the selected sector are the same as temporary PN codes determined using the temporary ID cell are determined. When the temporary ID cell is not duplicated and the temporary PN codes are not duplicated, the selected temporary ID cell is allocated as an ID cell of the selected sector.

摘要： An apparatus and method for determining operation of location update in a broadband wireless communication system are provided. The apparatus includes a receiver, an interpreter, and a determiner. In an idle mode, the receiver receives a paging advertisement message from a Base Station (BS). The interpreter identifies paging group identification information included in the paging advertisement message. The determiner determines one of execution and non-execution of a location update process due to a change of a paging group if the paging group identification information is different from paging group identification information included in a previously received paging advertisement message.
