Dynamic adjustment of the maximum period between overhead-message transmissions on a paging channel

摘要

Exemplary methods and systems are disclosed herein that may help to prevent pages to the same mobile station from being repeatedly shed in order to send overhead messages. An exemplary method may involve a base station: (a) detecting a page-shedding event; (b) in response to detecting the page-shedding event, adjusting a maximum period between overhead-message transmissions; and (c) transmitting at least one overhead message according to the adjusted maximum period between overhead-message transmissions. A page-shedding event typically involves an overhead message being sent in a given paging-channel slot instead of a page that was previously scheduled for the given paging-channel slot. Preferably, in order that a page is not repeatedly shed in the same slot during the slot cycle, the maximum period between overhead-message transmissions may be adjusted such that the slot cycle duration is not a multiple of the maximum period.

1. A method comprising:
initially transmitting, by a base station, one or more overhead messages according to a first duration of a maximum period between overhead-message transmissions, wherein each of the one or more overhead messages must be sent at least once during the duration of every maximum period; the base station subsequently detecting a page-shedding event; in response to detecting the page-shedding event, the base station adjusting the maximum period between overhead-message transmissions from the first duration to a second duration, wherein a adjusting the maximum period between overhead-message transmissions comprises setting the maximum period between overhead-message transmissions equal to a period of which a slot cycle duration of the base station is not a multiple; the base station transmitting the one or more overhead messages according to the adjusted maximum period between overhead-message transmissions; and after transmitting the at least one overhead message according to the adjusted maximum period between overhead-message transmissions, the base station readjusting a maximum period between overhead-message transmissions back to a default period.
