Methods and messages for performing handovers between an unlicensed mobile access network (UMAN) comprising a first radio access network and a second radio access network. URR (UMA radio resource) handover messages are exchanged between a mobile station (MS) and a UMA network controller (UNC) operating in the UMAN. The MS may access the UMAN via a wireless access point (AP) that is communicatively coupled to the UNC via an IP network. The URR handover messages are sent between the MS and the UNC using an Up interface comprising a set of layered protocols over an underlying IP transport. The handover methods include both handover from a UMAN to the second radio access network, and handover from the second radio access network to the UMAN.

A method to facilitate user equipment (UE) handoff within a packet data communication system includes determining, at a source relay node, that the UE is to undergo a handoff from the source relay node to a target entity and sending, by the source relay node, a first request to a network node serving the UE. The sending is performed responsive to the determination that the UE is to undergo the handoff, such that the first request is configured to cause the network gateway node to store packet data addressed to the UE. Further operations include sending, by the target entity, a second request to the network, such that the second request is configured to cause the network to forward the stored packet data to the target entity, and receiving, at the target entity from the network, the stored packet data for wirelessly transmitting to the UE.

According to a particular embodiment, a method for assisting in a handoff is provided that includes receiving signaling from one or more access points, which may transmit information to a mobile station. The information may be used to execute a handoff from an enterprise network to a cellular network or from the cellular network to the enterprise network.

A system and method for determining timing offset errors in a low earth orbit satellite system based upon Doppler and Doppler rate of change is provided. A user terminal determines first and second timing offsets respectively associated with first and second satellite beams from respective first and second satellites. Next, the user terminal determines the Doppler and Doppler rate of change associated with the first and second satellite beams. A timing offset is estimated from the measured Doppler and Doppler rate of change and is then compared with the user terminal's own determined timing offset. If the comparison does not produce a value within a predetermined threshold, a beam identification error is declared.

A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a cellular station. The controller selects a downlink reference signal associated with a candidate beam among a plurality of downlink reference signals including Channel State Information-Reference Signal (CSI-RS) resources, Synchronization Signal (SS) blocks, or Physical Broadcast Channel (PBCH) blocks, and determines one from a plurality sets of Physical Random Access Channel (PRACH) preambles and RACH occasions for the selected downlink reference signal according to an association configured between the downlink reference signals and PRACH resources. Also, the controller uses the determined set of PRACH preamble and RACH occasion to perform a PRACH transmission to the cellular station via the wireless transceiver.

A mobile node (MN), a take-over point of attachment (PoA) and handover methods thereof for use in a heterogeneous wireless network system are provided. The heterogeneous wireless network system comprises a gateway, a first wireless network and a second wireless network which is heterogeneous to the first wireless network. The first wireless network and the second wireless network comprise the take-over PoA and an original PoA respectively. The take-over PoA and the original PoA have an overlapping service area. The MN receives a network service from the gateway via the original PoA so far. As soon as the MN enters the overlap service area, the MN builds a link with the take-over PoA in the data-link layer immediately so that the original PoA may handover to the take-over PoA without interrupting the network service.
