Abstract: A UE activates a PS Data Off service to block downlink and uplink services except the exempted services determined by the HPLMN. To activate PS Data Off, the UE sends an indication to the MME or SGSN, or additionally to a S-CSCF or an IMS network. The UE may receive a confirmation of the PS Data Off activation and/or a list of exempt services. The MME may contact the HSS to notify about the activation of the PS Data Off and receive indication of support of the service or list of exempted services and send the indication and/or packet filtering per PDN to PDN GW(s). The PDN GW may contact a PCRF to get policy rules. The HSS may provide a list of exempt services to the S-CSCF.
