Method and apparatus in a distributed messaging system for reducing networking traffic required to obtain subscriber information

摘要

4Dummy subscriber information records (226) are programmed (502) into a database of a local controller (110), and templates (222) are also stored (504) in the database. Each template includes a range of subscriber numbers (406, 408) belonging to subscribers of a home controller (120) different from the local controller, and a pointer (412) to a corresponding dummy subscriber information record (226). When the local controller receives (506), from a message originator, a subscriber number that falls within the range of subscriber numbers of one of the templates, the local controller obtains (508) subscriber information (418, 420) from one of the dummy subscriber information records through the pointer of the one of the templates.
