Abstract:
A method for reducing energy consumption of mobile devices using a phase-continuous early paging indicator (EPI) is provided. For each of at least one paging occasion either A) an EPI indicative that a page is present in the paging occasion is transmitted during an EPI occasion in advance of the paging occasion, the EPI comprising at least one phase-continuous tone for the EPI occasion, and a page is transmitted during the paging occasion, or B) an EPI indicative that a page is not present in the paging occasion is transmitted during an EPI occasion in advance of the paging occasion, the EPI comprising at least one phase-continuous tone for the EPI occasion. A mobile device is configured to monitor for an EPI that comprises at least one phase-continuous tone for an EPI occasion in advance of its paging occasion in order to determine if a page is potentially present.
