Abstract: A method and user equipment in a mobile telecommunications system for conducting a multimedia broadcast/multicast service (MBMS) session. An MBMS-uplink channel is introduced for transmitting from the user equipment, MBMS participation requests prior to the session and acknowledgment messages when MBMS messages are received. Relevant charging information is collected from the user equipment using broadcast/multicast services when an acknowledgment message is received. The telecommunication system then sends a decoding key to the user equipment for decoding at least a part of the data that is broadcast by the MBMS service.

Abstract: A method and apparatus for reducing handover interruptions when a mobile device executes handover including a random access procedure is described herein. When handover is desirable, a time offset associated with a random access opportunity is determined. The time offset relates the timing of the next random access opportunity to the frame timing of a target access point. Based on the time offset, a network element, e.g., the mobile device, a serving access point, or a mobility management entity, determines a handover start time. Handover is executed at the determined start time to generally align the beginning of the handover execution with the beginning of the next random access opportunity, and therefore, to reduce handover interruption.

Abstract: A retransmission correction performed by counting means (70) provided in a controlling radio network controller (RNC) (4a-c) within a radio access network (3) in the counting of multimedia service joined mobile terminals (7) located in a cell (6) for a PTP/PTM transmission decision, in the case of a repetition of a multimedia service session. The retransmission correction uses an estimated number of the mobile terminals having received a previous transmission of said multimedia service session from any radio network controller.

Abstract: In a multi-access communication system, a terminal is kept reachable through a first access network, which is most resource efficient one of the available access networks for keeping the terminal reachable. The terminal scans passively for the existence of usable base stations for other access networks of the system and reports data associated with such existences to the first access network. When a request for a call to the terminal is received, a paging is performed in the first access network. The paging message comprises information about preferred access network, based on the reported data of the existence of usable base stations or access points of other access networks. The terminal connects to the preferred access network and performs a call set-up directly in the preferred access network.

Abstract: A radio base station transmits data symbols to a mobile terminal on multiple frequency carriers, e.g., in accordance with the MC-WCDMA or cmda2000 3x air interface protocols. The radio base station instructs the mobile terminal to report channel quality measurements obtained by the terminal for the multiple carriers over the same uplink channel during successive reporting intervals. According to one embodiment, the mobile terminal reports channel quality by receiving data symbols transmitted on a plurality of frequency carriers in a multi-carrier CDMA environment and measuring channel quality for the different frequency carriers. The mobile terminal reports individual ones of the channel quality measurements over the same uplink channel during successive reporting intervals.

As disclosed, control of measurement occasions are decided on by the UE using Discontinuous Reception during Forward Access Channel reception. Using aspects of the disclosed embodiments, each UE individually decides when to perform inter-frequency/RAT measurements (provided performance requirements on cell reselection are met). Outer coding procedures may then be performed to recover data lost during the measurements.

Abstract: In a mobile communication network (SYS) data transmission between a radio base station (RBS) and a subscriber station (UE) is carried out by successively transmitting frames. The radio network controller (RNC) inserts at the beginning of the respective frames an indicator flag (MOP) indicating to the subscriber stations (UE) whether the frame or a succeeding frame contains data which must be read and decoded by the subscriber stations (UE). The subscriber station can by reading and decoding the indicator flag (MOP) determine that there is no necessity to read data from the present frame or a succeeding frame and can therefore use the time period of one or more frames to save network resources or to perform inter-frequency measurements on another frequency. The invention finds particular application in a WCDMA mobile communication system.

Abstract: The present invention provides event-based or driven reporting of mobile station measurements. A mobile station measures one or more radio-related parameters for one or more cells in a radio access network. The mobile station evaluates the measured radio-related parameter with respect to a predetermined condition or event and determines that the predetermined condition is satisfied or that the event has occurred. Based on that evaluation, the mobile radio sends a report to the radio access network. Accordingly, the occurrence of an event and/or the satisfaction of a condition triggers the sending of the report to the network. That way, the network receives the information so that it can take timely and appropriate action without sending outdated or redundant measurement reports that do not convey relevant or new information.
