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.

A method, system, and mobile station are presented for informing a packet control unit (PCU) whether the dual transfer mode (DTM) capable mobile station has an ongoing circuit switched connection and is in dedicated mode. The packet control unit will typically be located at a base station. Upon entering the dedicated mode, the mobile station alerts the PCU of entry into the dedicated mode, using a mobility management (MM) procedure. This mobility management procedure is utilized for alerting the PCU about the dedicated mode, regardless of physical movement of the mobile station such as movement from one cell to another.

The invention relates to a method for controlling the use of transmission resources, wherein transmission resources for a transmission between a first entity (200) and a second entity (204) can be used by at least a first connection (205) and a second connection (219), comprising checking (208, 211) whether QoS requirements of said first connection (205) can still be guaranteed when said transmission resources are jointly used by said first connection (205) and said second connection (219), and controlling (212) the use of at least one portion of said transmission resources by at least one of said first (205) and second connections (219), accordingly. Said connections may for instance be packet-switched (205) and circuit-switched (219) connections in a General Packet Radio System that is capable of Dual Transfer Mode (DTM).

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.

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.

The present invention discloses a system and method of re-distributing power output by a portable mobile communications device while operating in dual transfer mode (DTM). The device determines if more than one uplink slot is active 320 and if DTM is active 330. If so, power can be separately regulated 350 for packet switched and carrier switched uplink slots. The device determines whether the circuit switched slot is being used for a voice call that is not in a handsfree or speakerphone mode 510 and evaluates factors associated with the current operating conditions 520. New power settings are calculated 530 based on the mode for the active circuit switched slot and the factors associated with the current operating conditions of the device. The new power settings are then applied 540 to the active uplink slots such that power is re-distributed on a per slot basis that is not necessarily divided equally among all active slots.

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.

The invention provides a method and a system for acquiring neighbor cell information. The method comprises the following steps that: an ENB (Evolved Node B) indicates a user to read system information block (SIB) information sent by a network side according to basic neighbor cell information acquired in an automatic neighbor relation (ANR) measuring process; and the ENB receives the SIP information reported by the UE to update the neighbor cell information. The ENB can indicate the UE to acquire the neighbor cell information by reading the SIB information so that the ENB can select a suitable moving manner and a target cell when the UE moves according to supporting capabilities of each neighbor cell on PSHO (Packet Service Handover), VOIP (Voice Over Internet Protocol), DTM (Dual Transfer Mode), HSDPA (High Speed Downlink Packet Access), HSUPA (High Speed Uplink Packet Access) and the like, so that the use experience of a user and the whole performance of the system are improved.

A method for the handover of dedicated as well as shared resources for a communication device. The communication device simultaneously uses circuit switched and packet switched bearer services of a communication network according to a certain connection mode. The method comprises performing a handover procedure, wherein a change from old resources used by the communication device to new resources to be used by the communication device is effected simultaneously for dedicated as well as shared resources .

The present invention discloses a node (207, 217) for achieving co-existence of single radio voice call continuity, SR-VCC, solutions in a communication system between a source cell of a first radio access network that supports packet switched voice and a target cell of a second radio access network that supports at least circuit switched voice. The node (207, 217) is operable to perform bearer splitting by separating voice bearers from non-voice bearers based on information about support for dual transfer mode, packet switched handovers and voice over internet protocol related enhancements in the target cell.
