US 7,352,717 B2 · Performing network control at active base transceiver stations and a base station controller

Abstract

A method for performing network control in wireless communication systems and a network entity for performing the same. The method and network entity pool at least one network parameter at the network entity, from at least two active set base transceiver stations and determine a current status of a mobile in the wireless communication system, using the pooled network parameters. The active set base transceiver stations may include a serving base transceiver station and a target base transceiver station. The network parameter may be a confidence metric and/or an error metric for each of a plurality of hypotheses, a power up/power down signal, and/or a measured signal-to-noise ratio and/or energy parameter of a pilot signal from the mobile. The current status of the mobile to be determined may be the mobile's decision to switch to the target base transceiver station transceiver or which base transceiver station transceiver the mobile is currently communication with. The network entity may be a base station controller or a base transceiver station in the active set of base transceiver station transceivers for the mobile in question.

Dependent claims

A method of performing network control in which at least one network parameter from at least two active set base transceiver stations are pooled at a base station controller, the method comprising:

determining a current status of a mobile in a wireless communication system, using each of the at least one pooled network parameters, each of the at least one pooled network parameters including a confidence metric for each hypothesis of a plurality of hypotheses that is reported by each of the at least two active set base transceiver stations to the base station controller,
wherein the confidence metric associated with each hypothesis is accumulated after every N slots of at least one frame;
wherein the at least two active set base transceiver stations include a serving base transceiver station and a target base transceiver station and the current status of the mobile is its intention to switch to the target base transceiver station;
and
wherein determining the current status of the mobile includes adding the accumulated confidence metric for each of the plurality of hypotheses and selecting the hypothesis with a largest cumulative value of the accumulated confidence metric.
