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. ## Claims ### Claim 1 A User Equipment UE, configured to support PS Data Off, said UE configured to perform at least one of: send a PS Data Off indication towards a Packet Core Network, indicating whether the user wants the blocking of uplink and downlink PS Data for non exempted services or not, send a PS Data Off indication towards a IMS Network, indicating whether the user wants the blocking of uplink and downlink PS Data for non exempted services or not. ### Claim at position 2 2-32. (canceled) ### Claim 33 An apparatus comprising: at least one processor; and at least one memory including computer program code. the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: receive an indication indicating whether packet switched data off is activated for a user equipment, receive an indication indicating a list of exempted services which are allowed in case packet switched data off is activated for said user equipment, select an appropriate terminating access domain for said user equipment, taking into account said list of exempted services, in case packet switched data off is activated for said user equipment. ### Claim 34 (depends on 33) An apparatus according to claim 33, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform: receive at least one of said indications, from a serving call session control function. ### Claim 35 (depends on 33) An apparatus according to claim 33, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform: receive at least one of said indications, via third party registration. ### Claim 36 (depends on 33) An apparatus according to claim 33, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform: receive at least one of said indications, during a IMS registration procedure. ### Claim 37 (depends on 33) An apparatus according to claim 33, wherein said apparatus is comprised in a terminating access domain selection function of a service centralization and continuity application server. ### Claim 38 An apparatus comprising: at least one processor; and at least one memory including computer program code. the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: receive at least one of an indication indicating whether packet switched data off is activated for a user equipment, and an indication indicating a list of exempted services which are allowed in case packet switched data off is activated for said user equipment, send at least one of said indications towards a service continuity application server, to cause a terminating access domain selection function of said service centralization and continuity application server to select an appropriate terminating access domain for said user equipment. ### Claim 39 (depends on 38) An apparatus according to claim 38, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least one of: receive said indication indicating whether packet switched data off is activated for a user equipment, in a SIP message, receive said indication indicating a list of exempted services which are allowed in case packet switched data off is activated for said user equipment, from a home subscriber server. ### Claim 40 (depends on 38) An apparatus according to claim 38, wherein said apparatus is comprised in a serving call session control function. ### Claim 41 An apparatus comprising: at least one processor; and at least one memory including computer program code. the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: send towards a call session control function an indication indicating a list of exempted services which are allowed in case packet switched data off is activated for a user equipment. ### Claim 42 (depends on 41) An apparatus according to claim 41, wherein said apparatus is comprised in a home subscriber server.
