CODING OF HANDOVER MESSAGES BETWEEN NODES OF DIFFERENT RADIO ACCESS TECHNOLOGIES
First Claim
1. A method for establishing a wireless connection with a user equipment (UE) in a communication system including a source base station operating according to a first radio access technology (RAT), the method comprising:
- receiving, at the source base station, a handover message that comprises an indication of a default configuration for establishing a connection with a target base station and an indication that the connection with the target base station is via a second RAT different from the first RAT; and
transmitting, by the source base station, a handover command to the UE based at least in part on the handover message.

Abstract
Techniques are provided for efficient handover of a user equipment (UE) between base stations that operate using different radio access technologies (RATs). A handover message to a UE may indicate that the UE is to be handed over from a source base station operating according to a first RAT to a target base station operating according to a second RAT. The handover message may be configured to be transmitted using the first RAT and include embedded information, that is transparent to the first RAT, for the handover to the target base station using the second RAT.

13. A method for establishing a wireless connection with a target base station in a communication system including a source base station operating according to a first radio access technology (RAT), the method comprising:
-
receiving, at a user equipment (UE), a handover command from the source base station, the handover command comprising an indication of a default configuration for establishing a connection with the target base station and an indication that the connection with the target base station is via a second RAT different from the first RAT; applying, at the UE, a configuration associated with the second RAT based at least in part on the indication of the default configuration and the indication that the connection with the target base station is via the second RAT; and initiating, by the UE, handover to the target base station via the second RAT based at least in part on the configuration associated with the second RAT. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. An apparatus for establishing a wireless connection with a user equipment (UE) in a communication system including a source base station operating according to a first radio access technology (RAT), the apparatus comprising:
-
a processor; memory in electronic communication with the processor; and instructions stored in the memory and executable by the processor to cause the apparatus to; receive, at the source base station, a handover message that comprises an indication of a default configuration for establishing a connection with a target base station and an indication that the connection with the target base station is via a second RAT different from the first RAT; and transmit, by the source base station, a handover command to the UE based at least in part on the handover message. - View Dependent Claims (23, 24, 25, 26)

27. An apparatus for establishing a wireless connection with a target base station in a communication system including a source base station operating according to a first radio access technology (RAT), the method, comprising:
-
a processor; memory in electronic communication with the processor; and instructions stored in the memory and executable by the processor to cause the apparatus to; receive, at a user equipment (UE), a handover command from the source base station, the handover command comprising an indication of a default configuration for establishing a connection with the target base station and an indication that the connection with the target base station is via a second RAT different from the first RAT; apply, at the UE, a configuration associated with the second RAT based at least in part on the indication of the default configuration and the indication that the connection with the target base station is via the second RAT; and initiate, by the UE, handover to the target base station via the second RAT based at least in part on the configuration associated with the second RAT. - View Dependent Claims (28, 29, 30)
