Method, system, mobile communication terminal and a node adapted for en-to-end quality access selection of an access network

The invention claims a from one or more it is able to mobile communication station for providing service access network selects the access network method for the: Confirming the terminal to each access network the radio quality; For each access network determining at least one node the use of the power factor; For each access network based on the access network said determined by making use of the power factor and said determined by the radio quality to determine whether the user sensitive data quality; And based on the determined a user of the sense quality selects the access network when at least one of. So as to improve the user sensitive data quality.
