Abstract:
1. A method of configuring proximity detection in a user equipment (UE) transitioning from one radio resource control (RRC) cell state to a different RRC cell state within a wireless communication system, the method comprising: receiving proximity detection configuration information from a network of the wireless communication system to configure proximity detection in the UE; configuring the proximity detection in the UE based on the proximity detection configuration information, receiving a radio bearer reconfiguration message as part of a procedure to configure the UE from using a first RRC cell state complying with a third generation (3G) wireless specification to using a second RRC cell state complying with the 3G wireless specification, in response to the radio bearer reconfiguration message, reconfiguring the proximity indication reporting in the UE based on the first RRC cell state or the second RRC cell state; and invalidating or deleting the received proximity detection configuration information when the UE transitions to a RRC cell state different from the second RRC cell state indicated by the radio bearer reconfiguration message.
