Abstract:
1. A method for use in user equipment (UE) comprising first and second radio technology components on a single platform, comprising: detecting a Long Term Evolution (LTE) handover when a signal strength measure for a source becomes worse than a first absolute threshold and that a signal strength measure for a target becomes better than a second absolute threshold due to in-device coexistence interference, when a signal strength measure for the target becomes better than an offset relative to a signal strength measure for the source due to in-device coexistence interference, or when a signal strength measure for the source becomes worse than an absolute threshold due to in-device coexistence interference, or an Inter-Radio Access Technology (Inter-RAT) handover when a signal strength measure for the source becomes worse than an absolute threshold due to in-device coexistence interference; sending a message to request handover for the first radio technology component from the source to the target for a proposed minimum holding time; receiving a handover command message to handover the first radio technology component from the source to the target for a specified minimum holding time to establish a coexistence mode for the first and second radio technology components; and enabling the first radio technology component to handover the first radio technology component to the target for the specified minimum holding time so that the first radio technology component is not handed back to the source during the specified minimum holding time, thereby enabling the radio resources on the UE to be used by the second radio technology component without interference from/to the first radio technology component.
