A method, apparatus, and computer program for controlling device-to-device connections and associated quality-of-service parameters are presented. The quality-of-service parameters of an end-to-end connection through a plurality of different radio access networks are aligned in connection with changing a communication mode to a direct device-to-device connection.
摘要:
A method of controlling device-to-device communications between user equipment, including using a network control element, which is common to a plurality of networks, including controlling any of the following functions: network access control functions, connection set-up, resource allocation, mode switching, handover, security and/or charging. Also a method of controlling handovers or connections in a device-to-device communications between a first and a second user equipment wherein the control is performed, at least in part, said first or second user equipments. Alternatively the user equipment may send reports a handover/connection is initiated/controlled based on said report.

摘要:
Apparatus and method for communication are provided. The method includes storing a machine type communication channel access profile of user equipment configured to utilise machine type communication with a network when the equipment has not an active connection with the network. The access profile is based on active UE contexts including serving-cell contexts of the device on the last access occasion. The access profile is synchronised between the user equipment and the network.
摘要:
The present invention proposes methods and devices for mobile communication deployed on shared bands, which enhance reliability of channels such as control channels. According to an aspect thereof, at a communication terminal, a list of channels useable for communication is maintained, information on the usability of a currently used channel is obtained, and it is switched to one of the channels of the list of useable channels if the currently used channel becomes unusable. The invention encompasses also corresponding computer products as well as methods, devices and computer products residing at a network node.

An apparatus for providing network assisted local communication offloading to unlicensed bands may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured, with the processor, to cause the apparatus to perform at least receiving information indicative of channel conditions associated with primary communication involving at least one primary mobile communication device and a network communication node, and determining, at a secondary mobile communication device, primary communication resources to be utilized for secondary communication by the secondary mobile communication device based on the information indicative of the channel conditions. A corresponding method is also provided.
摘要:
A method for providing improved wireless connectivity for wireless devices operating in a heterogeneous multi-RAT environment may include receiving, at a network device, information indicative of one or more radio access technologies detected by a user equipment (UE) in corresponding locations where the received information is received in connection with a session initiation protocol (SIP) procedure, and causing provision of the received information to an access network discovery and selection function (ANDSF). A corresponding apparatus and computer program product are also provided.
摘要:
The invention concerns a method and an apparatus implementing the method. In the method at least one synchronization signal is received from a base station to a mobile node, which determining timing based on the at least one synchronization signal, for example, a group of orthogonal frequency division multiple access resource elements. The mobile node transmits an uplink radio resource reservation request to a base station. The mobile node receives from the base station an assignment of a radio resource dedicated for radio transmission to a remote node, the radio resource being within a band having a transmission power upper limit. The mobile node transmits a signal to the remote mobile node on the radio resource based on the timing determined.
