Abstract

A method for registering and controlling registration data for new and roaming pagers in a paging system. Messages for the pagers pass through an input messaging switch to the pager's home messaging switch, from which the messages are sent to an output messaging switch to be transmitted to the pagers. When a pager roams into and area, it sends out a registration message that is received by an output messaging switch. The output messaging switch then contacts the home messaging switch for the pager. The pagers are programmed with a home identifier, which they transmit as part of their registration message. The home identifier can be converted to the address of the pager's home node in home messaging switch. In this way, an output messaging switch knows which home messaging switch to contact when it receives a registration message from the pager. The home identifier in a pager can be reprogrammed through an over-the-air procedure. The home identifier in a pager can be reprogrammed through an over-the-air procedure. The home messaging switches an output messaging switches are able to send messages to one another in order to update and synchronize registration data. When a messaging switch is searching for a pager or a pager record, it can send a request message to multiple other messaging switches and will receive a response from only the messaging switch that has the required data. A special home node may be designated for the registration of new pagers.
