Title:
移動体データ通信ネットワーク内でのハンドオーバ中にヘッダ圧縮コンテキストを制御する方法
Document Type and Number:
Japanese Patent JP4435477
Kind Code:
B2
Abstract:
A method of an equipment for controlling header compression context during handover in a data exchange between a transmitter and a transmitter and a receiver of an IP mobile data network wherein data packets are transferred comprising a header portion and an information portion. The transmitter comprises a header compressor and the receiver comprisesa header decompressor arranged for operating in accordance with a header compression scheme. In the case of a handover the header compressor is notified of the initiation of a handover and starts transmitting packets arranged for controlling the header compression context between the header compressor and header decompressor. After completion of the handover, the header compressor is notified of the completion of the handover and resumes header compression in accordance with the header compression scheme during normal data exchange not involving a handover.
