RAN Rule and Condition Match Reporting for LTE-WLAN Interworking Control and Management

摘要

Methods for LTE-WLAN interworking control and management are proposed. In one novel aspect, a mobile termination (MT) can use an AT command to report the change of a RAN rule and/or a RAN condition match. A terminal equipment (TE) can use the AT command to query a list of matches and current RAN measurement values. A RAN rule match means one or more than one of RAN rules satisfy the threshold provided by the network according to TS36.304 description, or change from satisfied to unsatisfied. A RAN condition match means all RAN rules within a RAN condition are all satisfied according to TS36.604 description, or if any of the RAN condition change from satisfied to unsatisfied. If the reporting is enabled by TE, an unsolicited result code (URC) is sent from MT to TE whenever changes in the current RAN rule or RAN condition match occur.

主权项

1. A method comprising:
transmitting an ATtention (AT) command by a terminal equipment (TE) in a mobile communication network supporting multiple radio access technologies (RATs), wherein the AT command is related to a list of matches of radio access network (RAN) rules or RAN conditions based on a list of RAN offloading parameters; receiving a response including the list of matches from a mobile termination (MT), wherein the list of matches indicates whether a RAN rule match or a RAN condition match has changed for traffic steering between a first RAT and a second RAT; and performing RAT selection and steering data traffic based on the list of matches of RAN rules and RAN conditions.
