A source virtual machine (VM) hosted on a source server is migrated to a destination VM on a destination server without first powering down the source VM. After optional pre-copying of the source VM's memory to the destination VM, the source VM is suspended and its non-memory state is transferred to the destination VM; the destination VM is then resumed from the transferred state. The source VM memory is either paged in to the destination VM on demand, or is transferred asynchronously by pre-copying and write-protecting the source VM memory, and then later transferring only the modified pages after the destination VM is resumed. The source and destination servers preferably share common storage, in which the source VM's virtual disk is stored; this avoids the need to transfer the virtual disk contents. Network connectivity is preferably also made transparent to the user by arranging the servers on a common subnet, with virtual network connection addresses generated from a common name space of physical addresses.

Methods and apparatus provide paging control to a femto radio base station (28fj) of a radio access network (24). Paging to a femto radio base station (28fj) is controlled by maintaining a paging control database (46) of allowed user equipment units for which paging is permitted in a cell of a femto radio base station (28fj). The paging control database (46) is used to determine if a paging message for a target user equipment unit is to be forwarded to the femto radio base station. The database (46) thus serves to redefine the effective paging area by preferably including in the effective paging area only those femto radio base station for which the target user equipment unit is listed as a paging-allowed user equipment unit.

Methods and apparatus for efficient two-stage paging wireless communications systems are described. Wireless terminals are assigned to paging groups. A few first paging message information bits are modulated (using non-coherent modulation) into a first paging signal and communicated from a base station to wireless terminals. WTs wake-up, receive the first paging signal and quickly ascertain whether its paging group should expect a second paging signal, if so, the WT is operated to receive the second paging signal; otherwise, the WT goes back to sleep conserving power. The base station modulates (using coherent modulation) a number of second message information bits into a second paging signal and transmits the signal to WTs. From the information in first and second paging signals, a WT can determine that it is the paged WT and process the paging instructions. The intended paged WT can transmit an acknowledgement signal on a dedicated uplink resource.

Semi-connected state operation for UEs in multiple-access networks is described. In the semi-connected state, UEs may monitor system information and paging, and mobility may be UE-controlled. Base stations may determine whether to transition UEs from the connected state to the semi-connected state based on capabilities, priority, data connections, or loading conditions. Base stations may maintain context information and logical traffic connections for UEs while UEs continue to be served by the base station in the semi-connected state. Thus, when a transition from the semi-connected state to the connected state occurs, the base station does not have to re-establish security parameters, nor re-establish logical traffic connections within the network for carrying control plane and user plane data for the UE. Context information for semi-connected state UEs may be shared between neighboring base stations or base stations within a context area. The techniques may be applied to LTE / LTE-A networks.
