Methods and Systems for Responding to Handover Events During Positioning Sessions

摘要

Disclosed are systems, methods and devices for responding to changes in a wireless access type occurring in connection with a handover event affecting a mobile terminal while the mobile terminal is engaged in a position determination session with a location server. If a first positioning protocol employed in the position determination session is not supported or enabled by the changed wireless access type, the position determination session may be resumed or restarted using a second positioning protocol supported or enabled by the changed wireless access type.

主权项

1. A method of position determination for a terminal comprising:
detecting a handover of the terminal from receiving service through a first wireless access type to receiving service through a second wireless access type while said terminal is in a position determination session with a location server according to a first positioning protocol, wherein the second wireless access type is different from the first wireless access type; and in response to detecting the handover, initiating a transition to application of a second positioning protocol instead of said first positioning protocol, wherein the second positioning protocol is enabled or supported by the second wireless access type.
