System and method for reducing energy consumption of mobile devices using early paging indicator

摘要

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.

1. A method in a network component, the method comprising:
performing at least one of: A) for each of at least one paging occasion: transmitting, during an early paging indicator occasion in advance of the paging occasion, an early paging indicator indicative that a page is present in the paging occasion, the early paging indicator comprising at least one phase-continuous tone over the early paging indicator occasion; transmitting a page during the paging occasion; or B) for each of at least one paging occasion: transmitting, during an early paging indicator occasion in advance of the paging occasion, an early paging indicator indicative that a page is not present in the paging occasion, the early paging indicator comprising at least one phase-continuous tone over the early paging indicator occasion,wherein:
a given paging occasion is associated with a group of mobile devices, the group of mobile devices comprising a plurality of subgroups of mobile devices within the group; the transmitted page is for at least one mobile device of at least one subgroup; for each subgroup for which a page is to be transmitted during the paging occasion, transmitting, during the early paging indicator occasion in advance of the paging occasion, an early paging indicator indicative that a page is present in the paging occasion comprises transmitting an early paging indicator specific to the subgroup that comprises at least one phase-continuous tone over the early paging indicator occasion and that is indicative that a page is present in the paging occasion for the subgroup; and for each subgroup for which no page is to be transmitted during the paging occasion, transmitting, during the early paging indicator occasion in advance of the paging occasion, an early paging indicator indicative that a page is not present in the paging occasion comprises transmitting an early paging indicator specific to the subgroup that comprises at least one phase-continuous tone over the early paging indicator occasion and that is indicative that a page is not present in the paging occasion for the subgroup.
