A device for controlling the access of user equipments to broadcast MBMS-type services includes i) a detector for determining whether general information, related to a MBMS service and broadcast by the radio access network, contains configuration information for a MICH-type, notification transport channel dedicated to the MBMS service and ii) a controller for either forcing the user equipment to periodically monitor a MCCH-type logical channel which carries control information related to the service, in the event that the configuration information for the MICH channel is not determined, in order to retrieve information necessary for accessing the MBMS service; or at least suggesting that the user equipment monitor the MICH channel in the event that its configuration information is determined, in order to retrieve update information for the MCCH channel making it possible to monitor the MCCH channel, so as to retrieve the information necessary for accessing the MBMS service.

Device and method for controlling user equipment access to services of the MBMS type offered by a mobile network

A method for controlling the transmission timing of a radio link on an air interface between a radio terminal and a radio access node, in a radio access node adapted to transmit a plurality of radio links to a radio terminal with substantially simultaneous transmission timings, is disclosed. It is determined whether predetermined conditions are met so that a substantially simultaneous transmission of a first and second radio links to said radio terminal can be selected. Responsive to this determination, a substantially simultaneous transmission of the first and second radio links is selected.

Method and apparatus for controlling the transmission of radio links in a radio-communication system

In a method for multicast service continuity in a radio communications system, each radio network controller has a first identifier of each multicast service whose activation was previously requested by at least one radio terminal () via said radio network controller and is adapted to notify radio terminals in a corresponding coverage area of the start of at least one session relating to one of said multicast services, reported by a core network, said notification incorporating the first identifier of said service. With respect to a radio terminal () entering the coverage area of a drift radio network controller () after having been in the coverage area of a serving radio network controller (), the radio terminal having previously requested activation of a multicast service via the serving radio network controller, the first identifier of said service is sent from the serving radio network controller to the drift radio network controller.

Uninterrupted multicast service in a radiocommunication system

The invention concerns a method which consists, in a radio communication system comprising a core network, at least one radio network controller connected to the core network and configured to control radio communications with terminals and at least one operation center capable of supervising said radio network controller, in: transmitting from the operating center to a radio network controller, a coded list of terminal identifiers; transmitting the coded list to the control network from the radio network controller; decoding the coded list at the core network; detecting at the core network a radio communication under the control of the radio network controller, with a terminal identified in the decoded list; and instructing the radio network controller, from the core network, to start a recording of events concerning the detected communication.
