A method performed by a source Radio Network Controller (RNC) for handling a relocation of a User Equipment (UE) connection from the source RNC to a target RNC to serve the UE in an ongoing wireless communication is provided. An interface between the source RNC and the target RNC is available. When all radio links in the ongoing wireless communication are controlled by the target RNC and a triggering condition is fulfilled for relocation of the UE connection from the source RNC to the target RNC, the source RNC decides () to discontinue to use said interface. Then a core network is used for sending () to the target RNC, a triggering of the relocation procedure for relocating the source RNC to the target RNC to serve the UE. A Radio Resource Control (RRC) configuration defined by the target RNC to be used after the relocation to the target RNC is then obtained () via the core network. The RRC configuration, defined by the target RNC, is sent () to the UE enabling the UE to switch from an RRC configuration defined by the source RNC to the RRC configuration defined by the target RNC.

In a vehicular network having a plurality of connected user equipment, experiencing a change in an available bandwidth a method for adapting to the change is performed comprising the steps of collecting information about the users and the bearers, detecting a change in bandwidth available for the local network, identifying user equipment in the local network to be affected by said detected change, notifying the identified user equipment of an adaptation of the bandwidth for the identified user equipment, and finally adapting the bandwidth of each identified user equipment.

Method and arrangement for adapting to variations in an available bandwidth to a local network

Systems and methods are provided for reducing signal distortion during tandem free operation signal transmission from a first mobile station to a second mobile station over a network; the systems and methods reduce the signal distortion in tandem free operation mobile to mobile communications that occurs when there is a loss of synchronicity between a plurality of transcoder rate adapter units that is caused by oscillation of the transcoder rate adapter units between different functional states during signal transmission. The systems and methods of the invention reduce the time gaps that are associated with these oscillations, resulting in reduced signal distortion and improved signal transmission.
