Abstract
The present invention concern methods and apparatuses for transporting and using time zone information in an internet protocol multimedia subsystem, IMS, network. When a cali session control function, CSCF, node (115, 125) receives (501 ) a request message related to a user equipment, UE, the CSCF node (115, 125) retrieves (502) and (503) stores time zone information associated with the UE. The time zone information is sent (504) by the CSCF node (115, 125) 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 (115, 125) may optionally create (505) an Attribute Value Pair, AVP, including the stored time zone information and send (506) a charging message including the AVP to a charging node, to enable usage of the time zone information in charging.
