Abstract: In a handover of a mobile station (12) from a base station (14-1) to a base station (14-2), the base station (14-2) determines ANCH2 to be allocated to the mobile station of a operation frequency band of the base station (14-2), and notifies the mobile station of the determined ANCH2 via a CCH. The mobile station shifts, when a timeslot of ANCH2 is different from a timeslot of ANCH1, a operation frequency band of the mobile station in the timeslot of ANCH2 from a operation frequency band of the base station (14-1) to a frequency band which contains ANCH2. The mobile station then establishes a connection to the base station (14-2) via ANCH2, disconnects the connection to the base station (14-1), and completely shifts the operation frequency band to the frequency band of the base station (14-2).

Abstract: Systems and methodologies are described that facilitate automatically configuring a network configuration parameter (e.g., cell size parameter, . . . ) in a wireless communication environment. Size of an area served by a cell associated with a base station can be detected automatically by the base station. For example, size of the area served by the cell can be detected based upon location information of UE(s) served by the cell, a path loss between the base station and the UE(s) served by the cell, and/or a transmit power level of a reference signal sent by the base station. Moreover, a value of a network configuration parameter (e.g., cell size parameter, . . . ) can be automatically assigned by the base station as a function of a comparison between the size of the area served by the cell and a set of thresholds. For instance, the set of thresholds can be configurable by a network operator.

Abstract: A data segment of a data packet destined for an egress port of an egress node may be received at a first ingress node. An egress statement vector and an ingress statement vector may be identified at the first ingress node. A determination may be made, based on the egress statement vector and ingress statement vector, whether the first ingress node is authorized to transfer the data segment to the egress port before the other data segments of the data packet are received at the first ingress node. The data segment may be transferred to the egress port before the other data segments of the data packet are received at the first ingress node when the determination indicates the first ingress node is authorized. The data segment may be stored in a buffer of the first ingress node when the determination indicates the first ingress node is not authorized.

Abstract: Levels of power reduction for signals to be transmitted from a mobile communications device via radio channels in a digital wireless communications system, where each signal is modulated according to one of a number of modulation configurations, are determined. For each modulation configuration a first estimate of a power reduction is calculated (101), and the calculated first estimates are storied (102) in the device. The method comprises the steps of determining (103) a limited set of modulation configurations, said limited set comprising modulation configurations that have been determined likely to be used in practice; calculating (104) for each modulation configuration of the limited set an optimized estimate of a power reduction; and storing (105) the calculated optimized estimates in the device. In this way the power consumption of the device is reduced while keeping a look-up table at a reasonable size.
