Abstract
A time stamp of a message from a sending mobile device may be modified to correlate with the time zone occupied by a recipient mobile device. A message from a sending mobile device may be received at a message center. The message center may then route the message to a switch that manages the recipient mobile device, in which the switch is in a time zone that is different from the time zone occupied by the recipient mobile device. Accordingly, the switch may update a time stamp of the message to correlate with the time zone occupied by the recipient mobile. Following the update, the switch may transfer the message with the updated time stamp to the recipient mobile device.
Claims25
A computer-implemented method, comprising:
- receiving at a switch a sending mobile device message from a message center, the switch managing a recipient mobile device of the message, the switch being in a first time zone that is different from a second time zone occupied by a recipient mobile device;
- updating a time stamp of the message at the switch to correlate with the second time zone occupied by the recipient mobile device;
- and
- transferring the message with the time stamp to the recipient mobile device.
A computer-readable medium in a switch storing computer-executable instructions that, when executed, cause one or more processors to perform acts comprising:
- receiving a message having a time stamp that indicates a time value and a time zone designation for the time value at the switch, the switch and a recipient mobile device of the message being in different time zones;
- when the time zone does not match an additional time zone occupied by the recipient mobile device of the message, updating at least the time value in the time stamp to correlate with the additional time zone and transfer the message to the recipient mobile device;
- and
- when the time zone matches the additional time zone, transfer the message to the recipient mobile device without updating the time stamp.
A computer-implemented method, comprising:
- detecting a mobile device establishing a communication link with a switch of a mobile telecommunication network;
- obtaining a location code and cell identifier combination for the mobile device that indicates a current location area of the mobile device;
- correlating the location code and cell identifier combination to a time zone using a code mapping table that associates each location code and cell identifier combination of a plurality of location code and cell identifier combinations with a corresponding time zone;
- and
- sending time data that correlates with the time zone to the mobile device.
A switch comprising:
- one or more processors;
- and
- a memory that includes a plurality of computer-executable components, the plurality of computer-executable components comprising:
- a time stamp extraction component that extracts a time value and a time zone designation from a time stamp of a message for a recipient mobile device that is in a different time zone from the switch;
- a time zone comparison component that compares a time zone indicated by the time zone designation to an additional time zone occupied by the recipient mobile device;
- a time stamp update component that replaces the time stamp with a modified time stamp, the modified time stamp including a replacement time value that is adjusted based on a time difference between the time zone and the additional time zone, and an additional time zone designation for the additional time zone;
- and
- a function module that delivers the message with the modified time stamp to the recipient mobile device.
