Abstract:
A method of operating a telecommunications network comprises performing, at a sending node (20), compression on at least a portion of a header portion of the packet and encryption on at least a portion of the packet in a manner whereby the compression and the encryption are bound to an extent that, at a receiving node (22), verification of decompression and decryption of the packet are interdependent.

Abstract:
User equipment in a wireless communication system monitors scheduling information and locally detects a change in link data rate of the uplink channel based on the monitored scheduling information. In this way, a change in link data rate can be detected directly without significant delay. This direct or early detection of a rate change is then combined with an appropriate system reaction. The information of the detected change in link data rate is preferably utilized for adapting the application data rate of an IP application running in the user equipment. As an alternative, or as a complement, data packets are classified based on relative importance and selected for transfer of information over the uplink channel based on the classification of data packets and in dependence on the detected change in link data rate.
Abstract:
A method in a user equipment for handling a scheduling request is provided. The user equipment comprises a buffer. After receiving data arriving into the buffer to be transmitted to a base station, the user equipment triggers a scheduling request. The scheduling request is pending until it is cancelled. The user equipment cancels the pending scheduling request in response to determining that either the scheduling request is accounted for in a buffer status report to be included in a scheduled data transmission to be transmitted to the base station, or all data will be included in a scheduled data transmission to be transmitted to the base station.
Abstract:
A method (400) for use in a cellular system with at least one controlling node (110), eNodeB, which controls user terminals, UEs (130), in a cell (120). According to the method, a UE can be in one of at least two different states (410), an idle state, a DRX state, and an "on duration" state. A UE (130) can receive at least a first (420) and a second (425) type of traffic from its eNodeB (110). If (415) the first type of traffic is received by a UE during an on duration period, the UE assumes the idle (DRX) state at the end of the on duration period, and if (430) the second type of traffic is received by the UE during an on duration period, the UE prolongs the current on duration period by a certain amount of time.
Abstract:
The embodiments of the present invention relate to a method and arrangement in a telecommunication system, in particular to methods and arrangements relating to overlapping MBSFN-areas. A notification mechanism is introduced that allows a user equipment to distinguish notifications for different MBSFN areas and different MBMS Control Channels. The user equipment then knows already upon reception of the notification whether it has to wake up and read a specific MBMS Control Channel. The embodiments of the present invention thus support multiple MBSFN areas per cell while still maintaining the benefits of reduced battery consumption in the UE due to said MBMS notification mechanism.
