摘要： The teachings relates to method (40) in a target network (node16) of a target core network in a first domain during handover, in the first and in a second domain, of a communication device (20) from a source radio access network to a target radio access network. The source radio access network comprises a source access node (11) and the target radio access network comprises a target access (node12). The method (40) comprises determining (41) whether the communication device (20) has access admission to the target core network; when a hand over fails generating (42) a hand over failure message comprising an information element “Independent domain HandOver”, where in the information element is set to a predefined value indicating whether the hand over failed due to lack of access rights or for other reasons than lack of access rights. The teachings also relates to devices and further to methods in source nodes.

摘要： Techniques for performing radio link measurements while a wireless device is operating in an extended DRX mode are disclosed. An example method, implemented by a wireless device in a wireless communication network, comprises waking up (510) in advance of a scheduled DRX on-time, and outside of any other scheduled DRX on-time, for at least one measurement interval, performing (520) radio link measurements during the at least one measurement interval, and determining (530) whether the wireless device is in an in-synch or out-of-synch status. In some embodiments, the in-synch or out-of-synch status and/or a radio-link failure are selectively reported to upper layers of the mobile terminal's protocol stack, e.g., to an RRC layer.

摘要： A network node serves a cell of a mobile network. The network node indicates an offset value to a user equipment in the cell. The offset value is added to a channel quality value measured by the user equipment for triggering a handover from the cell to a further cell of the mobile network. The network node increases the indicated offset value until a handover of the user equipment to the further cell of the mobile network is triggered. After the handover to the further cell, the network node receives an indication of a channel quality of a downlink control channel of the further cell as experienced by the user equipment, e.g., in control signalling of a further handover of the user equipment back to the cell or in a request to protect radio resources of the downlink control channel.

摘要： A telecommunications network has a packet switched domain for handling packet based calls and a circuit switched telephony domain for handling circuit switched calls. A node of the packet switched telephony domain decides whether to terminate a call to a user equipment using a packet based connection to the user equipment or using a circuit switched connection to the user equipment. In response to deciding to terminate the call using the circuit switched connection, the node sends, to a further node controlling routing of calls between the packet switched telephony domain and the circuit switched telephony domain, an indication that services related to the call are controlled in the packet switched telephony domain. In accordance with the indication, the further node may then adapt its control signalling with respect to a node of the circuit switched telephony domain.

摘要： A method of authorizing a message received at a node in a wireless network is disclosed. The message from a sender device is formed by a plurality of symbols and includes a first message integrity indicator located at a predetermined distance from the start of the message such that further symbols of the message are included after the first message integrity indicator. The position of the first message integrity indicator in the message is determined, and a cryptographic operation is performed on at least some of the symbols of the message before the first message integrity indicator so as to generate a second message integrity indicator before the first message integrity indicator is received. The first and second message integrity indicators are compared, and an indication that the message is not authorized is provided if the second message integrity indicator does not match the first message integrity indicator.

摘要： A technique for handling a status of a connection for a call is provided. The connection has a signal path and a media path towards a terminating side. The signal path includes nodes at least some of which are to be informed of the status by a signal packet that is forwarded towards the terminating side of the connection on the signal path. One node inserts a media resource in the media path of the connection. The media resource provides media for announcing the status of the connection at the terminating side of the connection. The node includes in the signal packet, which signals the status to one or more of the nodes that are further towards the terminating side, a suppression indicator controlling suppression of media resource insertion at the one or more nodes. The node transmits the signal packet towards the terminating side on the signal path.

摘要： The present disclosure relates to methods and to wireless devices for device-to-device communication. One of the methods includes configuring direct control messages and reference signals, based on capability and state of the wireless device with regards to device to device communication. The method further includes associating, in the wireless device, at least one direct control message to a synchronization reference signal, configuring the at least one direct control message and/or the synchronization reference signal, such that a recipient can identify the association between the at least one direct control message and the synchronization reference signal, using the configuration of the direct control message and/or the synchronization reference signal. The at least one direct control message is then transmitted.

摘要： A method of operating a first wireless communication device to perform D2D discovery includes obtaining multiple discovery message detection results, and determining a D2D discovery status of a second wireless communication device based on the multiple discovery message detection results. Using multiple discovery message detection results to determine the D2D discovery status of the second wireless communication device significantly increases the reliability of D2D discovery, thereby increasing the likelihood that a device available for D2D communication will be detected, while reducing the likelihood of false detections.

摘要： Systems and methods for control signal outer-loop adjustment are disclosed. In some embodiments, a method of operation of a network node in a cellular communications network is provided. The method includes transmitting a control signal and a data signal to a wireless device. The method also includes detecting an ambiguous state of reception of the control signal by the wireless device based on a feedback of reception of the data signal. The method also includes, in response to detecting the ambiguous state of reception, updating a link adaptation (LA) parameter used to choose a coding scheme and power level for transmission of information in the control signal. By updating the LA parameter in response to detecting the ambiguous state of reception, the network node may provide improved performance.

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.
