Abstract: The invention relates to methods and arrangements for an event triggered DRX cycle adjustment. A user equipment located in a serving cell of a mobile communications network monitors downlink communication at predetermined time intervals when operating in discontinuous reception mode. The user equipment also performs communication parameter measurements regarding at least one of the serving cell and one or more neighbour cells. After the occurrence of a first event, the user equipment sends at least one of measurement data and a first event report to the network. The sending is triggered by the occurrence of the first event. The monitoring is caused to be performed at shortened time intervals after the occurrence of a second event, wherein the second event is defined to indicate a higher probability of receiving a handover command than the first event.

Abstract: The invention provides, according to one aspect, a method of scheduling information in a communication system at serving cell change. When a serving cell changes for a user equipment (UE), it is determined whether the new serving cell belonged to the previous serving enhanced data channel (EDCH) radio link set (RLS). The user equipment then sends scheduling information (SI) in the first MAC-e protocol data unit (PDU) sent in uplink after completion of the serving cell change only when it is determined that the new serving cell did not belong to the previous serving EDCH RLS. In other words, the UE sends the SI at serving cell change only when the base station (node B) has also changed.

Abstract: A notification unit conveys a transmit timing of a signal to a target radio apparatus. A receiver receives the signal transmitted from the target radio apparatus with a neighborhood of the transmit timing conveyed.

When a state in which the receive timing lags the estimated receive timing occurs more than a predetermined frequency, the determining unit instructs the target radio apparatus to start a handover.

Abstract: An access terminal establishes a session with a first radio access network (RAN). As a result, the access terminal receives a Unicast Access Terminal Identifier (UATI) assigned by the first RAN and establishes configuration settings for radio communications between the access terminal and the first RAN. The access terminal moves from the first RAN to a second RAN. Before the access terminal has a session established with the second RAN, the access terminal receives a request from a user to originate a call. In response, the access terminal sends the second RAN a connection request that includes the UATI assigned by the first RAN. The second RAN evaluates the UATI included in the connection request and determines that it was previously assigned to the access terminal by another RAN. Based on this determination, the second RAN grants the connection request by assigning a traffic channel to the access terminal.
