Abstract: Methods and systems are described for injecting a signal, such as a test or calibration signal, into data sent by a scheduling unit to a radio unit in a radio access network. Monitoring, mapping, and/or prediction of data traffic can be carried out by components of the radio unit. It can then be determined what injection points for the signal will do the least harm to the regular data traffic.

Abstract: Embodiments of the present disclosure provide method and apparatus for antenna calibration. A method implemented at a first network device. The method includes receiving a first radio signal generated by the first network device via a receiver connected to an antenna of the first network device. The method further includes receiving at least one second radio signal from at least one second network device via the antenna of the first network device. The method further includes determining an impairment related to the antenna of the first network device based on the received first radio signal and the at least one second radio signal. There is a line of sight (LOS) path between the antenna of the first network device and the antenna of each of the at least one second network device.

Abstract: A control node and method therein to split and distribute processing task to multiple calculating nodes for synchronization of their data processing in a calculating system are disclosed. The calculating system includes a primary system input interface, a secondary system input interface, the control node and the multiple calculating nodes which are independent and perform data processing in parallel. The control node receives a second processing task from the secondary system input interface and splits the second processing task into a number of execution requests according to the number of the multiple calculating nodes. The control node queries any one of the multiple calculating nodes for a time reference retrieved from a time source common to all of the multiple calculating nodes and calculates an execute time for the execution requests to be processed in the multiple calculating nodes.

Abstract: A method performed by a wireless communication device (UE) adapted to operate in association with a cellular communication network supporting supplementary services is disclosed. The UE is adapted to configure settings of the supplementary services offered by a first type of cell using a first communication protocol, i.e. a layer 3 protocol as specified in 3GPP TS 24.010, in a first list, to configure settings of the supplementary services offered by a second type of cell using a second communication protocol, i.e. a XCAP protocol as specified in 3GPP TS 24.623, in a second list and to keep a third list of settings of the supplementary services used to synchronize the first and second lists when the UE switches from the first type of cell to the second type of cell.

Abstract: A method of a short message service (SMS) manager is disclosed for a wireless communication device supporting a plurality of SMS communication modes, wherein the method comprises receiving, from an application of the wireless communication device, an SMS transmission instruction comprising an SMS payload and an SMS message type characterizer, which comprises at least one of an SMS broadcast flag and an SMS grouping identifier.

Abstract: A SIP-based method for supplementary services configuration is extended by the introduction of means for a network to service supplementary services interrogation requests from a UE by responding to a SIP INVITE sent by the UE. The response may be a SIP message and include, e.g., in the SIP message body a machine-readable representation of the interrogated service's current configuration.

Abstract: A method of a short message service (SMS) manager is disclosed for a wireless communication device supporting a plurality of SMS communication modes. In one aspect, the method comprises receiving (from an application of the wireless communication device) an SMS transmission instruction comprising an SMS payload and an SMS message type characterizer which comprises at least one of an SMS broadcast flag and an SMS grouping identifier. The method also comprises selecting one or more of the plurality of SMS communication modes based on the SMS message type characterizer and causing transmission of the SMS payload as an SMS message using the selected one or more SMS communication modes.

Abstract: There is provided multimedia communications service handling in a user equipment. An on-going multimedia communications service is handled by the user equipment. During the handling a request for establishing a further multimedia communications service is received by the user equipment. The on-going multimedia communications service and the further multimedia communications service require access to a resource in the user equipment only capable of serving only one on-going multimedia communications service at a time. At least one of the on-going multimedia communications service and the further multimedia communications service is associated with a non-default application for executing multimedia communications services on the user equipment. Handling of the on-going multimedia communications service and the further multimedia communications service is then coordinated.
