Abstract:
1. A method of communication, comprising: receiving a handover message at an access terminal, wherein the handover message identifies a plurality of access points that have been prepared for handover, and wherein the handover message comprises configuration information for the plurality of access points that have been prepared for handover; receiving, prior to a determination of signal conditions indicating handover of the access terminal, an advance handover command from a serving access point instructing the access terminal to perform a conditional handover operation associated with the received handover message upon occurrence of a handover condition, wherein the handover condition relates to whether a serving access point received signal strength is less than or equal to a first signal strength threshold for a first defined period of time and whether a received signal strength of a signal received from one or more of the plurality of access points that have been prepared for handover is greater than or equal to a second signal strength threshold for a second defined period of time; determining whether the handover condition has occurred; and executing, by the access terminal, the conditional handover operation upon occurrence of the handover condition for an access point selected from the plurality of access points that have been prepared for handover by connecting, autonomously from the serving access point based on the advance handover command, to the selected access point according to the configuration information.
