The present invention concern methods and apparatuses for transporting and using time zone information in an internet protocol multimedia subsystem, IMS, network. When a call session control function, CSCF, node receives a request message related to a user equipment, UE, the CSCF node retrieves and stores time zone information associated with the UE. The time zone information is sent by the CSCF node to at least one other IMS network node, which is then able to support time zone based services and/or charging associated with the UE. The CSCF node may optionally create an Attribute Value Pair, AVP, including the stored time zone information and send a charging message including the AVP to a charging node, to enable usage of the time zone information in charging. |
