  • Patent number: 8996019
    Abstract: The invention relates to a method in a communication node (10,200,201,202,211,212,222) for commonly managing resources in a radio access network between different network access technologies, which communication node (10,200,201,202,211,212,222) is comprised in a radio access network of a radio communications network. The communication node receives (71) from a first local resource manager (111) of a first network access technology, a first report of information regarding resources needed per service associated with the first network access technology, which service is associated with a first local service priority. The communication node (10,200,201,202,211,212,222) then receives (72) from a second local resource manager (112) of a second network access technology, a second report of information regarding resources needed per service associated with the second network access technology. The service is associated with a second local service priority.

  • Patent number: 8694044
    Abstract: A first communication device and a method in a node serving a first cell of a first frequency for controlling transmission power of a user equipment in the first cell, comprising receiving data relating to a second cell of the first frequency from the user equipment and determining to power regulate the user equipment. Determining to power regulate the user equipment is based on determining that the second cell is a cell to which a soft handover cannot be performed and determining that the user equipment is within a range of a cell border of the first cell. That being the case, the method further comprises transmitting a control message to the user equipment to control the transmission power of the user equipment.
