Method and apparatus for controlling the application of selected IP traffic offload and local IP access

摘要

A method and apparatus are described for controlling the application of Selected Internet Protocol (IP) traffic offload (SIPTO) or Local IP Access (LIPA) services for a wireless transmit/receive unit (WTRU). The SIPTO and LIPA services may be performed over packet data network (PDN) connections. A user of the WTRU may be prompted to accept or reject the usage of the SIPTO or LIPA services. The user of the WTRU may request switching from SIPTO or LIPA services to non-SIPTO or non-LIPA services.

1. A method for use in a wireless communication network, the method comprising:
detecting that a connection with a defined IP network is suboptimal due to using a Selected Internet Protocol (IP) Traffic Offload (SIPTO) or Local IP Access (LIPA) service; determining that a new optimal connection is needed with a same defined IP network; and causing establishment of the new optimal connection with the same defined IP network based on the determination, on a condition that there are service flows that do not require IP address preservation, the new optimal connection is utilized, and on a condition that there are service flows that do require IP address preservation, the suboptimal connection is maintained.
