A user equipment "UE" comprising: a processor configured such that the UE receives a broadcast message from a non-Evolved Universal Terrestrial Radio Access "E-UTRA" access device, the broadcast message providing handover synchronization information of the non-E-UTRA access device related to one or more E-UTRA access devices, the handover synchronization information comprising an indicator indicating a synchronization state, wherein the synchronization state is a synchronized state or an unsynchronized state, and a list of the one or more E-UTRA access devices having the synchronization state indicated by the indicator, the synchronization state indicating whether the one or more E-UTRA access devices in the list are synchronized with the non-E-UTRA access device; and the processor further configured such that the UE: determines whether the non-E-UTRA access device and a target E-UTRA access device of the one or more E-UTRA access devices are synchronized based on the indicator; when the non-E-UTRA access device and the target E-UTRA access device are synchronized, determines whether a system frame number of the target E-UTRA access device is odd or even based on a timing offset between the non-E-UTRA access device and the target E-UTRA access device; and performs a random access procedure for an inter-radio access technology "RAT" handover from the non-E-UTRA access device to the target E-UTRA access device based on the received message and using an odd or even system frame number as determined. a processor configured such that the UE receives a broadcast message from a non-Evolved Universal Terrestrial Radio Access "E-UTRA" access device, the broadcast message providing handover synchronization information of the non-E-UTRA access device related to one or more E-UTRA access devices, the handover synchronization information comprising an indicator indicating a synchronization state, wherein the synchronization state is a synchronized state or an unsynchronized state, and a list of the one or more E-UTRA access devices having the synchronization state indicated by the indicator, the synchronization state indicating whether the one or more E-UTRA access devices in the list are synchronized with the non-E-UTRA access device; and the processor further configured such that the UE: determines whether the non-E-UTRA access device and a target E-UTRA access device of the one or more E-UTRA access devices are synchronized based on the indicator; when the non-E-UTRA access device and the target E-UTRA access device are synchronized, determines whether a system frame number of the target E-UTRA access device is odd or even based on a timing offset between the non-E-UTRA access device and the target E-UTRA access device; and performs a random access procedure for an inter-radio access technology "RAT" handover from the non-E-UTRA access device to the target E-UTRA access device based on the received message and using an odd or even system frame number as determined. determines whether the non-E-UTRA access device and a target E-UTRA access device of the one or more E-UTRA access devices are synchronized based on the indicator; when the non-E-UTRA access device and the target E-UTRA access device are synchronized, determines whether a system frame number of the target E-UTRA access device is odd or even based on a timing offset between the non-E-UTRA access device and the target E-UTRA access device; and performs a random access procedure for an inter-radio access technology "RAT" handover from the non-E-UTRA access device to the target E-UTRA access device based on the received message and using an odd or even system frame number as determined. determines whether a system frame number of the target E-UTRA access device is odd or even based on a timing offset between the non-E-UTRA access device and the target E-UTRA access device; and performs a random access procedure for an inter-radio access technology "RAT" handover from the non-E-UTRA access device to the target E-UTRA access device based on the received message and using an odd or even system frame number as determined.
