The present invention relates to an arrangement in a communications system participating in user station (UE;1) service request and/or access procedures and comprising a number of packet data support nodes (10), a number of charging and/or policy handling nodes (30) and a number of application functions (20) handling mobility management and call control of mobile user stations requesting and/or accessing services. The packet data support node(s) (10) comprise(s) means adapted to send first mobile user station identity related information over a first interface (Gx,Gy; Gx/Gy) to a charging and/or policy handling node (30), at reception of a request for bearer services from a mobile user station (1). The application function(s) (20) comprise(s) means for, at reception of a request for a service session (SIP) from a mobile user station (1), sending second mobile user station identity related information to the charging and/or policy handling node (30), over a second interface (Rx,Rx/Gq). The policy and/or charging handling node (30) comprises verification means (32) adapted to establish whether the request for a bearer service to the packet data support node (10) and the request for a service session to the application function (20) (AF; P/S/I-CSCF) originate from one and the same mobile user station (1).
