Radio access technology interworking

摘要

Radio access interworking technologies allow a target network to notify a source network that a mobile device has moved from source network to target network, wherein mobile device does not need to perform notification to source network. Further, source network can provide a first subset of overhead information to mobile device and, after moving to target network, mobile device can receive a second subset of overhead information from target network. Further, mobile device can perform prehashing prior to moving to target network based on a channel list received from source network.

主权项

1. A method for inter radio access technology interworking, comprising:
receiving, at a mobile device, a channel list from a source network, wherein the channel list includes a plurality of communication traffic channels for facilitating communication between the mobile device and a target network; calculating a target traffic channel of the target network by a processor based at least in part on performing a hash operation on one of the plurality of communication traffic channels of the received channel list, prior to the mobile device performing a handoff from the source network to the target network; storing the target traffic channel as prehash information; receiving, from the source network, a redirection message that comprises a channel list message; notifying the source network to suspend a session; and moving to the target network identified in the redirection message.
