In one non-limiting aspect thereof the exemplary embodiments of this invention provide a method, a computer program product and a mobile station operable in accordance therewith to originate a request at the mobile station to terminate reception of a Multimedia Broadcast/Multimedia Service radio bearer; and to transmit the request to a wireless network that is the source of the Multimedia Broadcast/Multimedia Service radio bearer. In another non-limiting aspect thereof the exemplary embodiments of this invention provide a method, a computer program product and a wireless network node operable in accordance therewith to receive a request from a mobile station to terminate reception of a Multimedia Broadcast/Multimedia Service radio bearer and, in response, to send the mobile station a PACKET TBF RELEASE message that includes an identification of the mobile station and a TBF_RELEASE_CAUSE value defined as Stop Receiving MBMS Radio Bearer.

Method, apparatus and computer program for terminating mobile station receipt of multimedia broadcast/multimedia service (MBMS) service bearer

A system and method for minimizing signalling loads due to mutual exchanges of information between neighboring cells in which the same session is transmitted, and for reducing the time required to transmit MBMS neighbor cell information messages in a serving cell when a higher level of signalling occurs, wherein all broadcast control channel (BCCH) carriers indicated in a BCCH allocation are monitored by a mobile station (MS). A list of the cells having the strongest non-serving carriers is updated as often as the duration of the running average for measurements of the BCCH allocation. Base transceiver station identity codes (BSICs) and neighboring cell indexes of BCCH carriers are added to an uplink radio link control/medium access control (RLC/MAC) message that is transmitted to a network. As a result, the network is provided with the identity of which cell the mobile station is most likely to reselect to upon reception of the uplink RLC/MAC control message carrying the BSICs and neighboring cell indexes of the neighboring non-serving BCCH carriers of the mobile station.

Enhanced assisted cell change

The problem of synchronization of the handover of the CS and PS resources to the same target cell during DTM handover is solved without affecting the performance of the CS handover. The mechanism of synchronizing the handover of the PS and CS resources is supported by the following functions: (1) resource indications on the CS and PS handover signalling to indicate to target cell network nodes that the CS and PS handover is ongoing at the same time for the same MS; (2) allocated resources indications on the CS and PS handover signalling to indicate to the source cell nodes that there are resources available in the target cell for CS and PS resources; (3) management of the synchronization of the CS and PS handover in the source and target cell.

Combined handover of the circuit-switched (CS) and packet-switched (PS) resources

The invention relates to control of transmission power in cellular networks, specifically in cells having transmitters in several frequency bands. The invention allows the network to control the maximum transmission power of a mobile station in more than one frequency band.

Power control

A method and mobile terminal are disclosed for use in a wireless communication system in order for the mobile terminal to be able to transition from a dual mode, in which a packet switched connection and circuit switched connection are used together, to a single mode in which packets are transferred. The mobile terminal is for receiving minimum system information necessary to perform the transition in an uninterrupted manner, instead of an interrupted manner. This system information is broadcast to the mobile terminal on a regular basis, and is also sent to the mobile terminal partly or entirely by point-to-point transfer if a piece of the minimum system information is missing due to inadequate broadcast reception or some other reason. This system information is then employed by the mobile terminal to transition from the dual mode to the single mode in the uninterrupted manner.

Enhancement of dual transfer mode when circuit switched resources are released

A system and method for reducing idle mode power consumption for mobile stations (MS) that have joined a Multimedia Broadcast/Multicast Service (MBMS) session and are waiting for the session to start. The invention is also directed to reducing the power consumption of an MS for which an MBMS session is inactive. In alternative aspects of the invention, the power consumption of mobile stations is reduced in the absence of ongoing MBMS session activity. Reduced power consumption is achieved by eliminating the need to read notification messages from an MBMS specific notification paging group when the notification message is for a different MBMS session than the paging group that the MS has currently joined.

Enhanced pre-notification procedure for GERAN MBMS

In case of both circuit-switched and a packet-switched connection handover from a source () to a target () radio access network or base station subsystem a new target ID indication message () is sent to a core network node () either from a core network element () or from the target radio access network or base station subsystem, depending on whether there is an interface (Gs) between the core network element and the core network node. In one embodiment, in contrast to the prior art, the new target ID indication message is mandated to only identify one target base station or target radio access network.

Utilizing a same target cell during circuit-switched and packet switched handover

A method and terminal are disclosed for use in a wireless communication system, in order for the terminal to transition from a dual mode, in which a packet switched connection and circuit switched connection are used, to a single mode in which packets are transferred. The mobile terminal is for receiving minimum system information necessary to perform this transition in an uninterrupted manner. This system information is sent to the mobile terminal automatically or on a regular basis, and is additionally sent to the mobile terminal partly upon request of the mobile terminal. A release indication is sent to the terminal separately from the system information, notifying the terminal that the circuit switched connection will be released, at which point a timer is started. The system information is employed by the mobile terminal to transition from the dual mode in the uninterrupted manner, if the timer has not expired.

Enhanced handling of system information messages when moving from dual transfer mode to packet transfer mode

Controlling the output power level of a dual transfer mode (DTM) capable terminal involves generating a network message. The network message may be a circuit-switched (CS) handover command and/or a point-to-point signaling message. A maximum output power level value is associated with the network message. The network message is transferred from the network to the terminal. A packet-switched (PS) output power level of the terminal is determined using the maximum output power level value received via the network message.

System, apparatus, computer program product and method for controlling terminal output power

A mobile terminal and method are disclosed for use in a wireless communication system in order for the mobile terminal to be able to transition to a dual mode, in which a packet switched connection and circuit switched connection are used together, from a single mode in which packets are transferred. A packet associated control channel is used to convey a radio link control or multiple access control (RLC/MAC) message, and meanwhile packet switched resources are maintained. Then a dual transfer mode assignment message is received, as a result of using the packet associated channel to convey the radio link or multiple access control message.

Enhancement of packet transfer mode when circuit switched resources are requested

A mobile device, system, and method are disclosed for use in a wireless communication system during the mobile device's transition from a dual mode, in which a packet switched connection and circuit switched connection are used together, to a single mode in which packets are transferred. When the circuit switched connection is released, packet resources are allocated by converting timeslots used for circuit switched connection traffic into timeslots used for packet data traffic. Also included is a new alert signal within an existing message to the mobile device during the circuit switched connection release phase, before completion of the circuit switched connection release phase, in order to inform the mobile device that the converting step will occur after release of the circuit switched connection.

Mobile device, system and method for enhanced channel allocation when radio resource connection is released while in dual transfer mode

A system and method for minimizing the gap in service during the reception of an MBMS session due to the reselection of a neighboring cell in which that MBMS session is not ongoing, wherein a mobile station (MS) indicates its target cell and MBMS service id (i.e., BSIC, neighboring cell index, and Temporary MBMS Group Identity (TMGI)) to a network by sending this information to the network in an RLC/MAC message, e.g., a packet downlink ACK/NACK or with a new message. If the network has resources available for allocation, the network is permitted to allocate these resources for the MBMS session indicated by the MS and send corresponding MBMS neighbor cell information to the MS upon receipt of the packet downlink ACK/NACK or the new message. When the MS receives the MBMS neighbor cell information, it will then reselect to the target cell identified by the MBMS neighbor cell information.
