| 20100097973 | METHOD AND APPARATUS FOR IDLE MODE NOTIFICATION IN CELLULAR COMMUNICATIONS SYSTEM - 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. | 04-22-2010 |
