Abstract

Methods may be used by a Multi Radio Resource Management function for assisting the control of a User Terminal's access to an access network domain in a radio communications network. The MRRM function is arranged to communicate with a first radio access network domain to which a first authorization entity, A1, authorizes UTs access, and to communicate with at least a second radio access network domain to which a second authorization entity, A2, authorizes UTs access. The methods include receiving at least one radio resource information message, RRIM, from the second access network domain, the message comprising at least one parameter value, X₂, of at least one radio resource parameter, P₂, related to the traffic load and/or the radio resource consumption and/or the characteristics of at least one radio traffic channel, associated with said second access network domain. The methods further includes: defining a criterion, C, for granting the UT access to the second access network domain, wherein C is a function of at least X₂; establishing whether C is fulfilled or not for UT; and instructing A2 that UT is authorized to access the second access network domain if C is fulfilled for UT and instructing A2 that UT is not authorized to access the second access network domain if C is not fulfilled for UT.
