WIRELESS DATA SESSION HANDOFF USING LOCATION UPDATE MESSAGE

摘要

A High Rate Packet Data (HRPD) wireless access network station (400) that accepting a data session handoff from a CDMA2000 1x base station. The wireless access network station (400) receives, from an access terminal (120), a location notification message with a valid Previous Access Network Identifier (PANID). The wireless access network station (400) further receives session parameters from a remote access network having a previous data session with the access terminal and determines if the PANID is consistent with the session parameters received from the remote access network. The wireless access network station (400) further has a data session controller (402,416) that, in response to determining the PANID is not consistent with the session parameters, establishes an RF traffic channel and connects a data session between the access terminal (120) and a Packet Data Serving Node (208) based upon the PANID received from the access terminal.
