摘要： In a mobile network with a plurality of access networks (210, 220), a control node (110) which is controlling access of a user equipment (300) to that one of the access networks (210, 220) which is currently used by the user equipment (300) determines an access capability of the user equipment (300) in said access network (210, 220), e.g. support of voice communication over packet switched access. The control node (110) provides an indication of the determined access capability to a subscriber database (150) associated with the user equipment (300). The indication may then be retrieved from the subscriber database (150) and be used to control termination of a connection to the user equipment (300).
