Local media rendering of a multi-party call, performed by a Client User Equipment. The media is encoded by each party in the call, and sent as a media stream to a Media server, and the media server receives a request for media streams from each Client User Equipment, each media stream in the request associated with a client priority. The Media server selects the media streams to send to each Client User Equipment, based on the request, and further such that the number of streams does not exceed a determined maximum number, which is based, e.g., on the available bandwidth.

Local media rendering

The invention involves local media rendering of a multi-party call, performed by a Client User Equipment (). The media is encoded by each party in the call, and sent as a media stream to a Media server (), and the media server receives a request for media streams from each Client User Equipment, each media stream in the request associated with a client priority. The Media server selects the media streams to send to each Client User Equipment, based on the request, and further such that the number of streams does not exceed a determined maximum number, which is based e.g. on the available bandwidth.

The present invention relates to cellular mobile radio systems, and more especially it relates to Code Division Multiple Access, CDMA, cellular mobile radio systems, particularly to transmission power control in such systems. A method and apparatus transmitting TPC bits with inherent out-of-sync information and transmission power differential determined on the basis of soft handover status information and out-of-sync status information is disclosed. An associated method and apparatus receiving the TPC bits and controlling transmission power accordingly is presented.

Method and system of transmission power control

The present invention is related to cellular radio communication network and a method and apparatus for ranking a set of neighbor cells associated with a first cell in the cellular radio communication network. For each cell member in said neighbor cell set, handover statistics reflecting how frequent said cell member is involved in handovers aiming at modifying active sets including at least said first cell to include said cell member are registered (). Based at least in part on the registered handover statistics for the different cell members in the set of neighbor cells, the cell members of said set of neighbor cells are ranked (). The invention also includes a method for controlling mobile station measurements wherein neighbor cells are selected for inclusion in a monitored set based on said ranking.

Method of ranking neighbor cells as candidates for an hand over

The present invention is related to cellular radio communication network and is a method for determining a Monitored set (MS) of cells associated with an Active set (AS) of cells by a particular ranking of the neighbouring cells associated with each of the cells in the Active set. A neighbouring cell list is created which contains for each active cell its neighbouring cells. These cells can be in a random order and can include other active cells. A scanning operation is done starting with the neighbouring cell (Cor C) on top of the list which belongs to the strongest active cell (C), whereby this cell will be included in the Monitoring set if certain conditions (3,4; respectively, FIG.). Next, the list associated with the next strongest active cell (C) is considered. This scanning is repeated until the maximum size of the Monitoring set has been reached.
