Title:
セレクティッドインターネットプロトコル（ＩＰ）トラフィックオフロード（ＳＩＰＴＯ）およびローカルＩＰアクセス（ＬＩＰＡ）モビリティーのための方法および装置
Document Type and Number:
Japanese Patent JP6582076
Kind Code:
B2
Abstract:
Methods and apparatus are described for supporting wireless transmit/receive unit (WTRU) mobility between Home (evolved) Node Bs (H(e)NBs) that are configured to communicate with a Local Gateway (L-GW). The H(e)NBs and/or L-GW may belong to one or more Local H(e)NB Networks (LHNs). A WTRU may receive services including Selected Internet Protocol (IP) Traffic Offload (SIPTO) or Local IP Access (LIPA) services from the L-GW via one or more H(e)NBs. The WTRU may continue to receive SIPTO or LIPA services after a handover to another H(e)NB that may be in communication with the same L-GW and may belong to the same LHN. The WTRU may receive information related to the LHN or the L-GW to allow continuation of SIPTO or LIPA services as the WTRU moves among H(e)NBs and/or out of the LHN. The WTRU may receive and/or maintain one or more LHN Lists.
