Low capacity mobile assisted handoff in a cellular communications network
TLDR
In this article, a handoff control method for a telecommunications network consisting of a land system and a plurality of mobile stations is presented, where each cell is divided into a first region where evaluation of measurement values is performed and a second region where the evaluation of values is not performed.Abstract:
A method of controlling handoff in a telecommunications network is provided, the network including a land system and a plurality of mobile stations, the land system including a plurality of cells, the method comprising the steps of dividing each cell into a first region where evaluation of measurement values is performed and a second region where the evaluation of measurement values is not performed, performing an evaluation of measurement values when a mobile station enters the first region, and controlling the handoff based on the evaluation of measurement values.read more

Mobile communication method and radio base station
TL;DR: In this article, different methods for determining whether or not a synchronization state is established in the uplink, are used depending on whether a dedicated uplink dedicated resource is set up.
Patent
Soft hand-off in cellular mobile communications networks
TL;DR: In this article, the authors proposed a soft hand-off operation involving more than one of the said base transceiver stations (20) of the network, in which the mobile station (40) includes, in one or more such uplink signals transmitted thereby, respective signal measures for all of the BSs involved in the operation, each signal measure serving to indicate the performance of a communications channel between the mobile node and BSs concerned.

Measurement reporting in a telecommunication system
Oscar Salonaho,Kari Sipilä +1 more
TL;DR: In this article, the authors present an idea to specify at least two different triggers for sending a measurement report from the mobile station to the network. But the idea is to specify the triggers to be used in different measurement report types.
Patent
Imminent change warning
TL;DR: In this paper, the authors present a method for notifying a digital cellular telephone user of an imminent communication disconnection by generating at least one condition indication representative of at least 1 communication condition, analyzing the condition indication, determining whether a communication disconnections is imminent, enhancing quality of received communication signals when possible, and notifying the user of a user's inability to disconnect the phone.

Mobile communication method, radio base station, and mobile station
Mikio Iwamura,Anil Umesh +1 more
TL;DR: In this article, the authors proposed a mobile communication method which includes the steps of: transmitting simultaneous transmission capability information from a mobile station UE to a radio base station eNB, the simultaneous transmissions capability information indicating whether or not the UE can transmit uplink data signals via multiple carriers in the same sub-frame.

Neighbor-assisted handoff in a cellular communications system
Anna Fallgren,Claes Andersson +1 more
TL;DR: In this paper, a handoff system where handoff requests are initiated not only by a home or serving base station, but also by neighboring base stations is proposed. But the handoff request may come from a home base station because of a poor call connection or from a neighboring base station due to a possible strong call connection.

Method and apparatus for handing-over a radio connection from one radio cell to another radio cell of a digital radio transmission system
TL;DR: In this paper, the reception quality of the co-channel message transmission channels of remote base stations is additionally measured in the mobile station during the existence of a radio connection to a near base station.
Patent
Mobile assisted handoff
TL;DR: In this paper, a method for communication and handoff in a cellular mobile radio system and a base station and a mobile station for communication, in which time slot identifier codes are transmitted in bursts in times slots in frames of radio channels used for time division communication channels was proposed.
