Handling time information in communications systems

摘要

A method of handling time information in a communications system (100) comprising: receiving a message at a proxy entity such as a P-CSCF (110, 112, 114) in an IP Multimedia Subsystem (IMS) core network (108); determining a time zone offset between a local time of a terminal and a core network time; providing the time zone offset to a network element (116) in the core network; and generating a time stamp in the network element adjusted to correspond to the local time.

1. A method of handling time information in a communications system comprising:
receiving a request message requesting a communication service at a proxy call session control function entity in a core network, the proxy call session control function entity being one of a plurality of proxy call session control function entities of the communications system that serve respective visited networks, the visited networks having respective time differences with respect to a core network time; including in the request message at the proxy call session control function entity a time zone offset between a local time and the core network time, the time zone offset being a time difference with respect to the core network time, expressed in plus or minus units of time, or zero, between the local time and the core network time; and providing the request message requesting the communication service including the time zone offset to a different network element in the core network to enable a time stamp to be generated in the core network adjusted to correspond to the local time.
