Title:
【発明の名称】パケット交換通信ネットワークにおけるネットワーク制御ハンドオーバのための方法と装置
Document Type and Number:
Japanese Patent JP2003514443
Kind Code:
A
Abstract:
A method and apparatus for facilitating network controlled handover in a wireless network employs packet switching and use of shared resource, such as timeslots, and provides network element controlled handover of a mobile unit (28), such as by a base station system (14, 16), by providing packet routing for a plurality of mobile units to facilitate handover of at least one mobile unit. The base station system (14,16) employs a memory (308), such as a database or other suitable memory, that contains stored radio resource requirement data (309), such as PDP context information, on a per mobile unit basis. By having the packet routing, storage and maintenance of shared radio resource requirement data (309) on a permanent basis at the base station system level in a network, network controlled handovers can occur without the control of the packet switched network element that provides packets to the base station system.
