摘要： The present disclosure relates to methods and arrangements for re-establishing packet data transfer between a radio base station and a wireless device following radio link failure, the radio base station having pre-configured wireless device information. The RBS receives a request for re-establishment of the radio link from the wireless device. One or more DRBs are selected for re-establishment based on the pre-configured wireless device information. The RBS transmits a radio link re-establishment response to the wireless device comprising information about the selected one or more DRBs. The selected one or more DRBs are re-established upon receipt of a re-establishment confirmation from the wireless device, whereupon packet data transfer is resumed.

摘要： According to the invention data in a number of logical downlink intended for one or more mobile terminals are received in a first mapping unit, where at least a first High Speed Radio Network Temporary identity is allocated to these logical downlink channels addressing a group of mobile terminals for allowing transmission of channel data for reception by mobile terminals. A mobile terminal then reads, from a Broadcast Control Channel, necessary information including a High Speed Radio Network Temporary identity allocated to at least one logical downlink channel, where at least said first identity exists among possible identities. It then listens to a high speed shared control channel for the read identity. In case it detects the identity, the terminal follows a scheduling command, receives data on a high-speed downlink shared channel and processes said data.

摘要： Methods and apparatus for determining a security algorithm to be used for secured communications between a wireless terminal and a second node while the wireless terminal is dually connected to a first node and to the second node. An example method, implemented in the first node, includes determining (610) a first set of security algorithms, the first set including those algorithms supported by the wireless terminal. A second set of security algorithms is also determined (620), where the second set includes those security algorithms that are supported by the second node. In some embodiments, this determining (620) includes receiving information from the second node, the information identifying which security algorithms are supported by the second node. At least one security algorithm is then indicated (630) to the second node, wherein the indicated security algorithm is chosen from the intersection of the first and second sets.

摘要： For protecting transmission of a control message (60) in a mobile communications network between a first access node (10a) and a user equipment, an indication of at least one protected time-slot for transmitting the control message may be transmitted in response to a need for transmitting the control message (60). The indication is transmitted between the first access node (10a) and a second access node (10b). Transmission of the indication prompts reduction of spectral interference caused by the second access node (10b) during the at least one protected time-slot (30).
