A network entity apparatus and corresponding method and computer program product are also envisaged.

Apparatuses, methods and computer program products related to improvements in autonomous denial prohibition mechanisms

Apparatus, methods and computer program products operate an electronic device to receive through from a wireless communications network a prioritized list of radio access technologies; to store the prioritized list of radio access technologies in a memory of the electronic device; and to consult the prioritized list of radio access technologies during cell selection and reselection operations. In variants the radio access technologies listed in the prioritized list of radio access technologies can be E-UTRAN, UTRAN or GERAN. In a further variant to consult the prioritized list may mean to compare at least one of a signal measurement and a quality measurement with at least one threshold established for a certain radio access technology appearing in the prioritized list, and to select/reselect to the certain radio access technology only if the at least one of the signal measurement and the quality measurement exceeds the threshold.

Apparatus, method and computer program product providing priority setting for multi-rat interworking

There is provided a mechanism for controlling communications conducted in multiple frequency bands so as to decrease an interference level between the communications. When an interference situation caused between a first set UL communications performed on at least two different frequency bands and a DL communication performed on another frequency band is determined, a frequency carrier deactivation processing is conducted so as to deactivate either one of carriers of the at least two frequency bands of the set of UL communications. The deactivation processing includes for example an autonomous denial on the UE side or an interference reporting with deactivation on the eNB side.

Interference control mechanism in multi-band communication

A method, receiving device, network element, system and computer program product for controlling discontinuous reception at a receiving device of a communication network are disclosed. A regular discontinuous reception cycle of a discontinuous reception scheme is set, and this regular discontinuous reception cycle is switched to a shorter temporary discontinuous reception cycle or is switched off, in response to an event which triggers a reply of the communication network to the receiving device. Thereby, delays of network replies can be shortened or controlled in case discontinuous reception (DRX) cycles are implemented at the receiving device.

Method and system for providing reply-controlled discontinuous reception

The negative impacts on a user equipment (UE) caused by the UE's support in network self-configuration and optimization is limited to an acceptable level by controlling user equipment measurements in a network to configure neighbor lists; requesting one or more measurements; the user equipment performing measurements in one or more adjacent cells in response to one or more measurement requests; reporting the measurements; and identifying cells in the network to be included in the neighbor list such that the user equipment measurements support network self-configuration and optimization.

Mechanisms for controlling communications conducted in multiple frequency bands so as to decrease an interference level between the communications. When an interference situation caused between an UL communication performed on at least one frequency band and a DL communication performed on another frequency band is determined, a partial denial processing is conducted so as to deactivate a dedicated part of resource blocks used for the first communication on the at least one frequency band of the first communication in the case of an interference situation being determined. The first communication is then continued in parallel to the second communication, on the basis of resources different from the dedicated part of resource blocks deactivated in the partial denial processing.

A mechanism for synchronizing transmission of frames in a telecommunications network including a mobile station, a radio network controller, at least one base station. The mobile station and each base station have a corresponding timing reference. The mechanism includes or performs the steps of establishing a connection-specific timing reference which is common to all nodes involved in the connection; determining, for the base stations an offset between the timing reference of the base station in question and the CFN; and using the offset in the base stations, to compensate for the difference between the timing references.

Frame synchronization mechanism

A method of operating a mobile station in a WCDMA system. The mobile station has a rake receiver () having a plurality of demodulator fingers (). One of the demodulator fingers monitors a neighbouring cell and other demodulator fingers monitor an assigned cell. When the mobile station is in an idle mode, if it is stationary, activity of the demodulator is reduced by switching off the demodulator finger which monitors the neighbouring cell.
