Abstract: Service node for a telecommunication network (15) and method for determining a group of n user terminals (21) which are closest to a point of interest (22). First, a search range with an upper limit (24) is set. Then in an iterative manner, a current search cell of the set of cells (1-10) is determined and the search cell is queried for user data. The user terminals (21) are added to a set of found user terminals, and if the set of found user terminals comprises n or more user terminals (21), the upper limit (24) of the search range is adjusted to the nth lowest distance. This is repeated until no further possible cell (1-10) can be determined. The set of criteria can be set and matched with obtained user data to find a closest user terminal (21) having a specific role.

Abstract: The present invention relates to a scheduler selector and a method for improving network quality by controlling intercellular interference of a multi-cellular mobile radio communication network.

Abstract: A method and apparatus for counting Media Access Control (MAC) address moves at line rate is described. According to one embodiment of the invention, a line card in a network bridge receives a frame at a port having a source MAC address that is associated with a different port of the network bridge. The line card signals a control card of the network bridge that the source MAC address has moved. The control card processes the source MAC address move and increments a MAC address move counter. If the MAC address move counter exceeds a MAC address move count threshold for a given time interval, the control card signals each line card in the network bridge to count each frame they receive on any port having that source MAC address. Other methods and apparatuses are also described.
