ABSTRACT:
A system and method of using one-way or two-way paging to establish communications with a mobile party and sensing duplicate pages. A one-way or two-way paging device operates to compare an incoming page with pages that have been received within a predetermined, and preferably subscriber adjustable, time interval. If the incoming page is determined as being identical to a page received and stored by the pager within the preceding predetermined time interval, then the incoming page is deemed a duplicate page, and is therefore disregarded. If the incoming page is determined as not being identical to any pages received within the predetermined time interval, then the page is deemed a new page, which is stored by the pager for comparison to any pages subsequently received within the predetermined time interval, and the paging device notifies the subscriber of the new page. In another embodiment, when a page is sent out to a two-way paging device by the paging system, the paging system updates a database which contains paging information for pages sent out to each subscriber. A two-way paging device that identifies an apparent duplicate page sends a reverse page query to the paging system, requesting confirmation as to the invalidity of the apparent duplicate page. The reverse page includes information that identifies the apparent duplicate page, and the paging system compares this information with that stored in the database to determine whether two separate pages matching the apparent duplicate page were transmitted by the paging system.
