Abstract: A handover apparatus is provided, comprising: means for receiving a handover request message from a first network element; means for sending a handover indication message to a second network element while sending a handover acknowledgement message to the first network element. The present disclosure manages to reduce the handover delay so as to enable fast handover for dual connectivity.

Abstract: Selective bearer splitting may be of benefit to various communication systems. For example, selective bearer splitting may beneficial to small cell systems of the third generation partnership project (3GPP) or similar systems. A method may include determining a capacity information regarding capacity of an interface between a first base station and a second base station. The method may also include selecting, on a per user equipment's bearer service basis, a data splitting point for at least one of a plurality of bearer services for a user equipment, based on the condition of the interface.

Abstract: Various communication systems may benefit from appropriate restriction on use. For example, certain wireless communication systems may benefit from radio-access-technology-specific access restrictions. A method can include registering a user equipment with a network element. The registering can include identifying user equipment capabilities. The method can also include receiving a response from the network element indicating restriction on use of at least one radio access technology.

Abstract: Methods and apparatus management of dual connectivity in wireless communications. A master base station belonging to a wireless communication network including the master base station and a secondary cell group including at least one secondary base station, configures one or more secondary cell group bearers for a secondary base station. Configuring the secondary cell group bearer includes configuring an inactivity timer for the secondary cell group. The inactivity timer is configured to indicate that, if no activity has occurred on the secondary cell group bearer during pendency of the inactivity timer, the secondary cell group bearer is to be released. The master base station then signals the configuration to the secondary base station.

Abstract: Data forwarding may be useful in many communication systems. Thus, for example, data forwarding support may be useful in dual connectivity in, for example, the third generation partnership project (3GPP) and more particularly to dual connectivity with enabled downlink (DL) data back forwarding. A method can include receiving, by a first network node, an indication indicating that for at least one split bearer, data received prior to the indication is to be forwarded to a second network node. The indication can also indicate that the at least one split bearer should be kept or maintained at the first network node. The method can also include, in response to the received indication, forwarding the data for the at least one split bearer received prior to the

Abstract: A method and apparatus can be configured to detect that a signaling strength of a first network entity has dropped below a threshold. The method can also include transmitting a measurement report to the first network entity. The method can also include receiving radio-resource-control reconfiguration information from the first network entity. The method can also include transmitting a scheduling request to a second network entity, wherein a random-access-channel procedure is avoided.
