摘要： The present invention relates to methods and devices for mobility management UE in a cellular communications system. A user equipment maintains (21) at least two sets of mobility trigger parameters. Each set of mobility trigger parameters corresponds to a predetermined user equipment speed range. The user equipment determines (22) a speed range that the speed of the user equipment falls into and selects (23), based on the determined speed range, at least one set of mobility trigger parameters to be used for performing mobility-based decisions. If the user equipment is in connected mode a network base station may select a set of mobility trigger parameters to be used for performing handover decisions based on a determined speed range of the user equipment. Advantages are that ping-pong mobility decisions may be avoided and it is sufficient to determine a range for the UE speed, which is less complicated than determining an accurate speed of the UE particularly in idle mode.

摘要： A method in a wireless terminal (110) for sending a measurement report to a serving base station (130) before handover is provided. The wireless terminal (110) and the base station (130) are comprised in a cell in a wireless communications system. The wireless terminal (110) is arranged to use a standard size message or a reduced size message for sending a measurement report before a handover. The wireless terminal (110) obtains (601) information about the cell size and/or the system load. When the cell size exceeds a predetermined value or when the system load exceeds a predetermined value, the wireless terminal (110) sends (605) a measurement report to the base station (130), using the reduced size message.

摘要： Mobility parameters, such as those used in handoff decisions, are based on the speed of User Equipment (UE) (10), measured at two points. UE speed estimates are taken at both the UE (10) and base station (12), and the two speeds compared. If the speeds match (or differ by less than a predetermined amount), one or more mobility parameters are adapted based on the UE speed. These parameters may include time to trigger (TTT), time to satisfy (TTS), measurement time, forgetting factor, β, measurement period (Tm), handover prohibit timer, MeasurementReportingmargin, HOmargin, hysteresis, and the like. The UE speed comparison may be performed at the UE (10) or at the base station (12). In one embodiment, a plurality of UE speed ranges are defined (e.g., low, medium, high), with corresponding mobility parameter values associated with each range.

摘要： The method according to the present invention provides synchronization in a heterogeneous mobile network, for the purpose of interoperability, of a wireless local area network, in which a medium is reserved for a certain service or user in radio channel reservation periods (702) of variable duration, to a radio access network, transmitting data in transmission time intervals of pre-defined duration (603). The variable duration of a radio channel reservation period (702) is defined such that it ends by a pre-defined time period (609) before the end of a transmission time interval (603). The method may be implemented in an access point (1400) of a heterogeneous network as well as in a mobile station (1500).

摘要： The invention relates to a method for selecting a radio access point of a network, and a method for transmitting information on at least two radio access points of a network to a mobile terminal. Further the invention relates to an adapted mobile terminal and control entity for performing the methods, respectively. To minimize the transmission delays of acknowledgement messages sent from a mobile terminal to a control entity, the invention provides an access point selection mechanism that determines for a respective one of the at least two radio access points, a selection criterion associated to the respective radio access point. This selection criterion may be based on a transmission delay for sending acknowledgement messages via a respective access point to a control entity. Based on the determined selection criterion the mobile terminal selects one of the at least two radio access points, and sends an acknowledgement message to the control entity through the selected radio access point.
