METHOD AND APPARATUS FOR IDLE MODE NOTIFICATION IN CELLULAR COMMUNICATIONS SYSTEM
First Claim
1. A method for idle mode notification by a Base Station (BS) in a cellular communications system, the method comprising:
- configuring a Multicast/Broadcast Service MAP (MBS-MAP) for MBS; and
transmitting an idle mode notification to at least one user in an idle mode using the MBS-MAP,wherein the idle mode notification indicates that the user at least one of waits for the next MBS-MAP and switches to a unicast channel to perform network reentry.

Abstract
An apparatus and method for idle mode notification in a cellular communications system is provided. A user transmits, prior to entering an idle mode, a de-registration request message to a Base Station (BS) which then transmits a Dynamic Service Addition REQuest (DSA-REQ) message to the user and adds the user to a multicast group for the idle mode, and enters the idle mode. The BS transmits an idle mode notification to the user using a Multicast/Broadcast Service MAP (MBS_MAP), and the user receives the idle mode notification, wherein the user switches to a unicast carrier to perform network reentry if the idle mode notification is a network reentry notification. The idle mode notification is considered as a service of an MBS type. When a user enters the idle mode, the BS actively invites the user to join the multicast group for idle mode notification if the MBS operates on a dedicated carrier.
