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 the 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, wherein the position determination session with the location server according to the first positioning protocol further comprises: determining a positioning measurement, communicating a position estimate to the location server or communicating the positioning measurement to the location server, or any combination thereof; and in response to detecting the handover, initiating a transition to application of a second positioning protocol instead of the first positioning protocol, wherein the second positioning protocol is enabled or supported by the second wireless access type.
