Abstract: A method and arrangement in a Radio Network Controller (RNC) for monitoring radio link (RL) synchronization for each RL as soon as it is added to a User Equipment's (UE's) Active Set. When a new RL is added, each RL in the Active Set sends an Active Set Update Complete message to the RNC. When the RNC determines that a Radio Link Restore Indication message is not received from the Target NodeB serving the new RL, the RNC starts an initRlSyncT timer set for a defined time period and monitors incoming messages to determine whether the Radio Link Restore Indication message is received for the new RL before the initRlSyncT timer expires. If so, the method ends; but if not, the RNC instructs associated NodeBs and the UE to remove the new RL from the UE's Active Set.

Abstract: A radio network controller (RNC) receives a request to activate a packet data protocol (PDP) context for a wireless device operating in a forward access channel state. The RNC sends the request to activate PDP context to a core network node (CN). The RNC receives a request to assign a radio access bearer from the CN. The RNC sends a response to the request to assign a radio access bearer to the CN and initiates a timer. If the CN accepts the request to activate the PDP context prior to timer expiry, the RNC stops the timer and sends the wireless device the accept message followed by a request to reconfigure a radio bearer. Otherwise, if the timer expires, the RNC sends the wireless device the request to reconfigure the radio bearer followed by the accept message.

Abstract: Devices and methods for intelligent handover requests and management are disclosed. IRAT handover failure can be prevented by ensuring that user equipment (UE) is asked to handover to a target cell that it has already measured, and that resource allocation in the base station sub-system (BSS) is made in the correct cell. For instance, a radio network controller (RNC) can maintain cell identification and corresponding node information when an updated measurement control message is sent to the UE. According to certain aspects, a relocation cancellation message can be sent from an RNC to a mobile switching center (MSC) if a new measurement report, such as a 3a report, is received by the RNC.
