Method and system for supporting multiple time zones and charging method and system in ims
The disclosure provides a method for supporting multiple time zones in an ip multimedia subsystem (ims). The method comprises: a proxy call session control function (pcscf) network element sends a session initiation protocol (sip) message including time zone information to a control layer network element exclusive of the pcscf network element (201); after obtaining the time zone information, the control layer network element receiving the sip message sends an sip message including the time zone information to a service layer network element (202); and the service layer network element receives the sip message sent from the control layer network element and obtains the time zone information included in the sip message (203).
